Learning styles in fact to face and online environments

Presentation Stakeholders in the training business have condemned online instruction in view of different reasons. In any case, it is rising that distinctions in understudy attributes might be a noteworthy supporter of the apparent deficiency of web based learning. One characteristic is understudy learning styles; if teachers find out about the connection between learning styles and training condition (on the web or eye to eye) at that point they may improve their outcomes.Advertising We will compose a custom paper test on Learning styles in certainty to confront and online situations explicitly for you for just $16.05 $11/page Learn More Relationship between learning styles and instruction condition (online versus conventional) The hypothetical model of learning style parts expresses that learning styles are subject to three key variables: understudy inspiration, task commitment and intellectual handling propensities (Aragon et. al. 2002, p. 233). They portray understudy inspiration as a learner’s state of inspiration when introduced by another undertaking. Some of the time, understudies may exhibit autonomous inspiration conduct or ward conduct. In different situations, inspiration could be avoidant or participatory. On occasion, it might be synergistic or serious. Undertaking commitment is the degree to which an understudy will focus on specific parts of their instruction. This might be demonstrated by their energy, fixation levels or the manner in which they take an interest in class. A student’s level of uneasiness, their mentality, focus, booking, testing methodologies and numerous different components outline the degree of errand commitment (Aragon et. al. 2002, p. 236). Psychological control is the way wherein a student forms data. The understudy for the most part shows this by their intelligent perception, which is one’s capacity to consider what they have watched. In specific conditions, this boundary could be showed as solid expe rience. Theoretical conceptualisation is likewise another method of exhibiting intellectual control, and the furthest edge of this range is dynamic experimentation. It is adroit to know whether online understudies have a more prominent inclination for intelligent perception or solid experience or whether they like to test effectively in class. A similar data is very valuable for customary understudies, too. Aragon et. al. (2002) completed an investigation of the contrasts between online students’ learning styles and conventional understudies. They discovered â€Å"traditional understudies were progressively viable at utilizing supporting materials and procedures than their online counterparts† (Aragon et. al. 2002, p. 236). In this manner, study helps are more appropriate in up close and personal settings than in online networks. Moreover, â€Å"online understudies like to utilize intelligent perception more than their eye to eye counterparts† (Aragon et. al. 20 02, p. 237). This implies the degree to which online understudies learn by observing and doing is more noteworthy than it is among conventional students.Advertising Looking for article on dialects?

This implies the web, as a strategy for showing conveyance, is equivalent with â€Å"learning by thinking† (Aragon et. al. 2002, p. 237). Up close and personal students have a more prominent inclination for dynamic experimentation contrasted with their online companions. This implies instructors in the customary condition should encourage educating through doing. On the other hand, instructors in the online network should grasp more reflection (Aragon et. al. 2002, p. 243). End Differences between favored learning styles in the up clo se and personal condition versus the online condition demonstrate that understudies obtain information in an unexpected way. In this way, teachers must consolidate those inclinations in the manner in which they convey material to their understudies. The two settings can yield positive outcomes if educators utilize the correct methodology. The primary distinction between the two gatherings is intellectual control as vis-à-vis understudies lean toward a hands-on approach while online understudies do well with intelligent reasoning.

We will compose a custom exposition test on The Rise and Decline of the Socialist party in America or then again any comparable theme just for you Request Now Communism as a political thought depends on agreeable proprietorship and redistribution of merchandise, administrations, and creation. The Socialist Party of America was one group whose roots are situated in communism. Made in 1901, the SPA was framed by the blend of the Social Democratic Party of America, a brief development, and the Social Labor Party, a working man’s party. This mix pulled in new individuals, just as individuals from the dynamic and populist parties, which made up most of the SPA. The ascent of the Socialist Party of America was filled by the working keeps an eye on want for an idealistic culture. Battle guarantees for open responsibility for, better sanitation, and a government managed savings program, at nearby levels, prompted the party’s highpoint in 1912. These little triumphs were brief. The American residents feeling of independence and pride just as a need securing news individuals and bolster set the wheels of disappointment moving. The party’s steadfast restriction to inclusion in World War I and the ejection of its individuals prompted The Socialist Party’s last second. Group polarization inside the gathering disabled a once brought together front, lastly President Roosevelt’s â€Å"New Deal† enactment successfully quieted the American Socialist gathering. The ancestry of the Socialist Party of America (SPA) can be followed back to the mid 1850s. The United States was a clamoring country brimming with circumstance. Interminable new eginnings and opportunities spoke to European residents who were searching for a superior life. Looking for a superior life, a blast in 1850 brought 1,713,000 outsiders through Ellis island, carrying alongside them their philosophical thoughts of socialisml . The bombed German transformation of 1848 acquired the displacement of Germans to America.

Alongside Germans, Italians, Finns, Jews, Hungarians, Ukrainians, Bohemians and Russians came to America toting their communist values2. Finns were especially solid in their communists thoughts.

Into the nineteenth century, German foreigners settling in Midwestern urban communities, for example, Milwaukee, Wisconsin, Dayton, Ohio, and St. Louis, Missouri put fourth significant sources of info and gave body to the development of communism in the United States. Foreigners to the United States were not by any means the only ones looking for change. The way of thinking ot communism in the states was seen witn no enthusiasm by American itizens. This has to do with the character of American culture and our perspectives. American culture has kept up a confidence in independence, financial progression, and equivalent open door in the marketplace4. To put it plainly, Americans put their confidence in private enterprise. Be that as it may, private enterprise doesn't generally bargain everybody a reasonable hand and there are irregularities in the market. This prompted arrangement of radical, outsider communist based developments in America’s customary two gathering political range. These outsiders were seen as radical in light of the fact that during the 1850’s to the 1930’s there was an outflow of profound doubt towards the development and ntervention of states by residents concerning their private affairs5. Options in contrast to communism were made. The Progressive party’s projects of unassuming state mediation through government authoritative order to protect singular rights, innovative qualities, and the major entrepreneur structure, spoke to numerous Americans as a moderate option to socialism6. The Populist party was one other outsider development the fiddled with communist thoughts. Running on a foundation of government mediation to counterbalance financial difficulties and forestalling neediness in cultivating and orking class families eventually prompted most of the gathering comprising of cultivating and common laborers families. Numerous Populists would leave to become socialists7. Out of these developments, a man named Eugene V. Debs would step forward to touch off and join what might at last be known as the Socialist Party of America. Eugene â€Å"Gene† Victor Debs Was conceived in Terre Haute, Indiana on November fifth, 1855 and kicked the bucket October twentieth, 1926 in Elmhurst, Illinois at 70 years old years old. Debs was one of the establishing individuals from the Industrial Workers of the World (IWW), an establishing individual from the American Railway Union and a democrat in the Indiana General Assembly. Eugene Debs would abandon a heritage just like the most notable Socialist in the United States8. In 1894, the American railroad vehicle maker Pullman Company diminished hours and wages yet not leases on lodging for their laborers. This brought about a strike by the representatives who at that point had Joined Debs’s American Railway Union. The strike was separated by President Grover Cleveland and Debs was detained for neglecting to contradict the strike as pioneer of the ARU9. In jail Debs sat back by perusing work composed by Karl Marx. Discharged in 1895, Debs had become a communist who accepted apitalism ought to be supplanted by another helpful framework. Debs was for pushed radical change, however was against the progressive brutality upheld by some notable left-wing political movements10. In 1897 Debs Joined Victor Berger to frame the Social Democratic Party (SDP). The SDP was a brief communist development that ran Eugene Debs as a competitor in the 1900 presidential political race. In the wake of accepting just . 6% of the votes, the Social Democratic gathering joined with the much littler group, the Socialist Labor Party of Americal 1 making the Socialist Party of America SPA) in 1901. The recently made SPA pulled in individuals with different connections to communism. Between the years ot 1 to 1912, the gathering developed trom 1 individuals to under 1 The segment areas of proposals voters went from the East coast toward the West coast with most of gathering individuals being in Midwestern states. The SPA drew support from Progressives, Populist ranchers over the heartland, associations and unionists with the most democratic 2 quality originating from foreigners. 13 The communist Journal Appeal to Reason14, a blend of articles and concentrates from radical communism based writers, for example, Karl Marks and Tom Paine, was selling 500,000 duplicates per week. Along these lines giving an approach to publicize their thoughts and gathering stage. The quality of the SPA was controlled by the individuals who utilized a vote to cast their voice. Neighborhood level triumphs dabbed the guide from East to West. New York state and New Jersey were two expresses that had reliable SPA voters because of workers. The Midwest end up being the place the most noteworthy centralization of SPA individuals dwelled. Ohio, Michigan, Illinois and Wisconsin were the solid holds comprised of German migrants and Populist ranchers. SPA individuals running as competitors attempted to speak to the working man. Open responsibility for, better city sanitation administrations for poor people, better work principles and a standardized savings program chose 70 chairmen into officel 5. SPA triumphs at the government level were little. Eugene Debs ran as a presidential competitor in each political race somewhere in the range of 1900 and 1912, and once in 1920. 1900’s political decision was bleak. Debs got just . 6% of the well known vote. In 1904 Debs Ran again and got an expansion in votes, 402,810 3% of the mainstream vote. Voter turnout in the 1908 political decision was marginally higher, 420,793 decisions in favor of Debs. The appointment of 1912 demonstrated the Socialist Party of Americas highpoint. There was 117,984 individuals from the SPA, and Eugene Debs got an aggregate of 901 ,551 votes, 6% of the mainstream vote. This was the most noteworthy appearing of any presidential competitor in any United States political decision. 6 At the flare-up of World War I in 1914, the SPA took a firm resistance against the war. They were against every single universal war yet not restricted to class fighting. This restriction to the war made enrollment decrease and began struggle inside the gathering itself. In 1919, The left Wing Section of the Socialist party developed as a group inside the Socialist Party of America. During a political decision to choose new board individuals from the SPA, it was seen that the Left Wing Section of the Socialist party was going to pick up most of seats. Those not in the group ruled against this and said that votes were thrown in false habits. These votes were not counted and the entire political decision was dismissed.

High Power Continuous Wave Fiber Laser System - Free Essay Example

Introduction of High Power Fiber Laser The optical fiber with very high surface-to-volume ratio and a strong waveguide effect provides the fiber based laser source the potential to generate high power laser beam with high quality. In addition to the capacity of generating raw optical power with high beam quality, the fiber laser system has other appealing features, such as supporting robust and compact system designs, allowing ultrashort pulse operation, offering a board wavelength tunability, and providing high gains. Those features stimulate the research on the high power fiber lasers system, and lay the foundation of novel appealing applications, such as remote material processing, aerospace and defense. In the past decade, a remarkable increase of the powers produced by fiber lasers with high beam quality has been achieved (see Fig.1). As a result, the high power laser becomes strong counterpart of the solid-state bulk laser, and penetrates rapidly into areas that formerly other lasers were used. Fig. 1. Progress in output power from diffraction-limited and near-diffraction-limited Yb-doped fibers . Literature Review In the early 1960s, the first fiber laser was demonstrated by Snitzer . The doped fiberà ¢Ã¢â€š ¬Ã¢â€ž ¢s potential for high optical gain was revealed by David Payne and co-researchersà ¢Ã¢â€š ¬Ã¢â€ž ¢ working on Neodymium- doped fibers in mid 1980s . In 2009, the high power fiber laser, which based on a specifically silica-host ytterbium-doped fiber-based laser (YDFL), obtained 10 kW output in the single-mode (SM) regime. Although architectures are different, the high-power fiber lasers and amplifiers are mostly archived with rare-earth-doped (RE-doped) double-clad fibers. The double-clad fiber, which was initially demonstrated in 1988, provided the option of cladding pumping, and proved to be one of the key technologies for power scaling. The structure of this double cladding is that the active RE-doped core is surrounded by a much larger à ¢Ã¢â€š ¬Ã…“inner claddingà ¢Ã¢â€š ¬? (see Fig. 2), and are encircled together by out cladding. The pump beam emitted by fiber-coupled high-power diode bars or other kinds of laser diodes is coupled into the inner cladding, and confined within it by an outer cladding. The confined pump beam will be absorbed into the core while it propagates along the fiber. The laser light is generated in the central core, and the laser light can have very good beam quality à ¢Ã¢â€š ¬Ã¢â‚¬Å" even diffraction limited beam. Thereby, by means of double cladding configurations one realized the conversion from low brightness pump to high brightness single-mode fiber laser output. As the spatial and angular pump acceptance [can be expressed as the product of area and the square of the numerical aperture (NA)] for the inner cladding is significantly improved to the core pump, Such conversion is more effective, and close to 5 orders have been demonstrated experimentally. Among high power RE-doped fiber lasers, the YDFL is notable in term of high power. The Ybà ¢Ã¢â€š ¬Ã¢â€ž ¢s broad absorption band extends from 900 to 980 nm (see fig 3), covering high power pump LDà ¢Ã¢â€š ¬Ã¢â€ž ¢s best performance wavelengths, offers a low quantum defect [energy difference between pump and laser photons] for pumping with 9xx nm LD and lasing above 1040nm. This superior property offers the potential for achieving very high power efficiencies and reducing thermal effects. In addition, lasing at wavelength above 1040nm, the Yd ion shows a simple four à ¢Ã¢â€š ¬Ã¢â‚¬Å"level structure, that excludes excited state absorption and also a variety of detrimental quenching processes allowing high doping concentrations, which means high pump absorption per unit length. On the contrary, the small quantum defect also has a usually unwanted consequence: the significant quasi-three-level behavior, especially when lasing at short wavelengths (less then 1040nm), that will cause a high threshold and decrease the power efficiency. Fig. 2. Structure of a double-clad fiber and principle of cladding-pumping The Nd doped laser emitting at 1060 nm is a four-level system, which means a lower laser threshold. Associated with the relatively advanced state of 808 nm diodes for pumping Nd:YAG, this made Nd the choice for high power fiber lasers in early stage. Todayà ¢Ã¢â€š ¬Ã¢â€ž ¢s high power pump diodes in 9 xx nm are sufficiently bright to make threshold unimportant for most quasi-three-level high power fiber lasers. These overcome the obstacle of ytterbiumà ¢Ã¢â€š ¬Ã¢â€ž ¢s higher threshold and raise advantages of a lower quantum defect and higher doping concentration with quench-free. The first single-mode Yb doped fiber laser with output power over 100 W was demonstrated in 1999 , and it illustrated that the advantages of Yb doped double cladding structure can support for further increase in the average power by scaling the size of the optical fiber and the power of pump diode source. Soon after that, the power of cladding pumped YDFL obtained the kilowatt level. Thereafter, by invest igating the large-area core design and fabrication, the single-mode operation in kilowatt level was realized that would not have been possible for Nd doping. Figure 3: Absorption and emission cross sections of ytterbium-doped germanosilicate glass, as used in the cores of ytterbium-doped fibers. Another sophisticated technique which is adopted in all double-clad fiber lasers at 3 kW and above, is tandem-pump [in-band pumping with high-brightness pump sources, such as one or several fiber lasers, or thin disk laser]. The tandem pump makes it possible to pump close to the emission wavelength so that the quantum defect heating will be low resulting in a reduced thermal load. Actually, some advanced solid-state lasers, such as thin disk laser, is well matched with requirements of in-band high brightness pumping source, and 1 KW level output thin disk laser pumped fiber laser have been realized. Nonlinearities are an issue to further increase the CW output power of the fiber laser. The fiber laser considered above such as in Fig. 1 has operated with linewidths in the 1à ¢Ã¢â€š ¬Ã¢â‚¬Å"10 nm range. In such system with cw operating, excepting at the extremely high powers or long delivery fibers, the stimulated Raman scattering (SRS) is a weak effect and is relatively easy to prevent. However, for output power above 10 kW, the Raman gain can become so high (tens of decibels) that a considerable part of the power is transferred to a longer-wavelength Stokes wave, reducing the power in the signal wavelength. There are some applications need single frequency sources which can provide light power with narrower spectral line width, such as coherent beam combination of multiple single frequency fiber sources with high power. This scheme offers a promising method for further power scaling, and consequently this stimulates interest in single-frequency power scaling. For narrow bandwid th, especially at linewidths less than 10 MHz, the SBS is the dominate nonlinearity and the severe obstacle for high power single-frequency fiber sources. The SBS can be suppressed with shorter fiber and larger mode field area, and output power of hundred watts has been reported with such schemes .However, this power is still less comparing with the bulk solid state laser. There are several options for SBS mitigation, including straining the fiber in order to broaden the SBS gain bandwidth, and reducing overlap between the optical and acoustic fields. The highest power high-gain fiber amplifier can archive 1.7KW. It was realized by combination of the modest spectral broadening with phase modulation and the fiber with enlarged effective mode area. The most effective way to mitigate nonlinearities (excluding self-focusing) is to enlarge the effective mode area by optimizing geometry designs and material choices of fiber structure. Unlike the passive power delivery fiber, this task is more challenge for active fiber, as doping-induced refractive index changing, and thermal stability will be issues. A straightforward design approach to maintain pure single-mode operation is to increase the core diameter, with the NA reducing correspondingly. However, the downside is the waveguide effect gets weaker, and consequently light is easier lost from the core when the fiber is bent. More works on fiber designs for addressing these challenges are related to photonic crystal fibers techniques. It is possible to make single mode operation in a multi-mode supported fiber, by building up preferentially amplify, or attenuate for specific mode, while the mixing or coupling between modes should be controlled to minimum. There have been works focu sed on using differential gain by selective RE doping across the core , and differential-bend-loss by controlled bending of the fiber. The leakage channel and chirally coupled core fibers are designed to selectively couple propagation mode to high loss mode. The high order mode but not the fundamental mode is coupled to leaky mode, which will substantially be attenuated. The multifilament core and multicore fiber arrange filaments or cores in a two-dimensional array. There are evanescent-field coupling among cores, and the overall structure can exhibit single-mode guidance with large mode area. Academic Objectives From the aspect of power generation, Investigation of advanced fiber for mitigating nonlinearity will be still the most critical issue in increasing the output power for cw fiber lasers. It has been estimated that the maximum single core output powers of the ytterbium doped fiber laser should be at several tens of kilowatts level based on present technique. However, single-mode operation is not indispensable for lots of high power lasers applications. The single or near single mode operation in the MM fiber which is developed by balancing the mode quality, the achievable power, and the damage threshold of the fiber, can offer possibilities to archive higher output power. In addition to that, as the emission wavelength of well developed thin disk laser is still covered by the Yb ionà ¢Ã¢â€š ¬Ã¢â€ž ¢s absorption band and is more close to the emission band of the Yb ion, the research on novel architecture using thin disk laser to tandem pump the special designed Yb doped fiber laser al so offers the potential to increase output power of fiber laser and develop novel fiber laser with useful function. The proposed research will focus on advanced fiber, especially for the evanescent-field coupled waveguides, also called multi-core fibers (MCF). The main aim is to design and realize novel types of active MCF for increasing the output power of fiber laser with good beam quality, and for suppressing the SBS effect. Besides that, Based on the advanced thin-disk laser, and the novel MCF fiber, the investigation on the novel laser architectures will also be performed. The Outline of the Project According to the above proposed objectives, the research work can be divided to two main phases. The first phase will be focused on fiber design and fabrication, and the expected deliverable is the novel active fiber with improved performance in nonlinearity mitigation and bending resistant. The other phase is about the novel fiber laser architecture, and investigation of the novel tandem pump configuration based on thin-disk laser will be performed. Mathematical Model and Design Strategy The main nonlinearities for cw operating fiber laser is SRS and SBS. Although both of them can be mitigated by the enlarged mode area, the SBS is still too strong for increasing the power of single frequency laser in the LMA fiber. The proposed research aimed to suppress the SBS in the LMA fiber for mitigating both SRS and SBS. According to the previous research, the SBS threshold can be expressed by : (1) The ÃŽÂ ±u is acoustic attenuation coefficient for the acoustic mode of order u, Aeff is the optical effective mode area, G(Ñ ´max) is the SBS effective gain coefficient at the peak frequency, K is the polarization factor. We can see form the equation. Beside the mode area, the SBS can be suppressed by increasing the acoustic loss, reducing the overlap integral, and the SBS effective gain coefficient. The is the normalized overlap integral of the electric and acoustic fields and it can be expressed as : (2) The E0 is the optical field associated with the fundamental mode, and à ?u the field of a longitudinal acoustic eigen-mode of order u. The overlap integral can be changed by modifying the fiber refractive index profile and acoustic velocity profile. The acoustic loss can be changed by glass composition design. As different dopants have different effects on optical and acoustic properties, it is possible to create suitable dopants profile in the core and cladding to reducing the overlap integral or increasing the acoustic loss. Table 1 is some common dopants used for making silica glass based fibers. The profile of the optical and acoustic field can be indicated by optical and acoustic refractive indices. Similar to the optical refractive index, acoustic refractive index is defined as na(r) = VL Silica /VL (r) , where VL(r) is the longitudinal acoustic velocity in the core, and VL Silica is the longitudinal acoustic velocity of pure silica glass. Table 1. Trend of optical and acoustic refractive index change of different dopants in silica GeO2 P2O3 TiO2 B2O3 F2 Al2O3 Optical refractive index à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Å" à ¢Ã¢â‚¬  Ã¢â‚¬Å" à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ Acoustic refractive index à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Ëœ à ¢Ã¢â‚¬  Ã¢â‚¬Å" One straightforward approach to modify the loss for optical and acoustic field of a fiber structure is created a type of optical guiding and acoustic anti-guides with a dopant material(Fig 4 (a)), such as Al2O3, and it has been demonstrated in . The other approach is to reduce optical and acoustic field overlap, with different dopants in the core (Fig 4 (b)). The resultant optical and acoustic refractive index profiles of above approaches are shown below. (b) Fig. 4. Dopant designs for reducing the overlap of the optical and acoustic fields The strategies shown in fig 4 are based on single core fiber. There are quite a few research works on improving the effective mode field in single core fiber, and it is little room to enlarge the effective mode field areas further without detrimental effect in single core fiber LMA. Recently, multicore fiber based LMA has been investigated as passive delivery fiber , and as active fiber in the novel laser architecture. The supported optical mode field of MCF can be designed by core size and core interval; the profile of the acoustic and optical field can be modified by the distribution of dopants and doping area size; and the loss of the optical and acoustic can be controlled by doping material. Thus, it is worth investigating a novel active MCF supporting a few modes or only single supermode with the reduced overlap between the acoustic and optical field. Optical Index Al Yb Ge F/B Acoustic Index Fig 5 the schematic of the proposed 19 core double cladding fiber A fiber design strategy to suppress the SBS is shown in Fig 5. An optical guide while acts as an acoustic anti-guide in the effective optical field areas of MCF will be fabricated by manipulating dopants in core and cladding, for example as shown in fig 5, by choosing Al2O3 in core and GeO2 in cladding. Because the fields of optical and acoustic are separated, the interaction between the optical and acoustic waves is weaker. Furthermore, the MCF will be designed to support a few modes or only one supermode, that benefits for manipulating refraction index to increase threshold of the SBS in the single mode MCF, as the à ¢Ã‹â€ Ã¢â‚¬  n=neffà ¢Ã‹â€ nclad of single mode MCF is larger than single mode single core fiber(SMF), for example, the index difference à ¢Ã‹â€ Ã¢â‚¬  n=neffà ¢Ã‹â€ nclad is 3.69ÃÆ'—10à ¢Ã‹â€ 4 in the case of the 19-core fiber reported in and only 1.60ÃÆ'—10à ¢Ã‹â€ 4 for the SMF, providing more room of à ¢Ã‹â€ Ã¢â‚¬  n for manipulating dopants. Finally, the reference value of parameters such as the diameter of each core, the core interval, and the doped areas of each core, will be archived by numerical calculation. Numerical Calculation The optical field in the waveguide can be solved by numerical calculation the Maxwell equations. Like the optical field, by numerical calculating the nonlinear acoustic equation, the acoustic field can be obtained. After that the SBS threshold can be calculated with equation (1), (2). From the nonlinear acoustic equation, we can obtain the equation that determines the longitudinal acoustic eigen-modes. The acoustic modes that contribute to the SBS associated with the optical fundamental mode have constant azimuth. Neglecting the damping factor, the radial distribution of such a mode can be expressed as: (3) The ÃŽÂ ©u is the acoustic frequency and the ÃŽÂ ²u is the propagation constant of the acoustic mode, VL(r) is the longitudinal acoustic velocity profile across the fiber. The wave equation for optical field in waveguide is derived from the general Maxwell and can be written as: (4) The EO is the optical field, ko=2p/l is the wave number of the optical field, and no(r) is the refraction index profile across the fiber. The optical mode is efficiently backscattered by the acoustic mode when the phase-match condition, ÃŽÂ ² = 2ÃŽÂ ²u, is fulfilled, where ÃŽÂ ² is the propagation constant of the optical field. The ÃŽÂ ² is determined by the optical wavelength ÃŽÂ », the effective refractive index no,eff, and it can be expressed as: ÃŽÂ ² =kono,eff=2pno,eff/l. Determined by the structure, the acoustic field in the proposed 19 core fiber is confined in the inter cladding, and the acoustic index can affect the confining effect. As the position of inter cladding is fixed, once the doping concentration is chosen, the acoustic field will be determined. The optical field in the MCF is determined by both the doping concentration and the geometry structure of the MCF. It is the geometry structure of the MCF provides the extra room to design the optical field with desired mode. The field of a longitudinal acoustic (à ?u) can be numerical calculated with finite-element method. beside the finite-element method, previous research has indicated the à ?u can be solved by utilizing the solver for optical scalar wave equation after defining a few new terms for acoustic wave. to numerical solve the equations (4), as numerical calculation by the finite element method is still valid when strong coupling exists between the different cores, the mode structure of the optical filed in the MCF is also calculated by finite-element method based on commercial available software such as Fimmwave or Comsol-Multiphysics. After knowing the à ?u and the EO, the can be calculated by taking the à ?u and E0 into equation (2). Finally, taking the into equation (1), the Pth of the designed fiber can be obtained. The theoretical M2 propagation factor can be computed with the method in. For a doping state, different Pth value and mode structures can be achieved for different geometry parameter, such as single core diameter and core interval. Optimizing the geometry parameter is necessary to get the high Pth value with good mode structures. Finally, repeatedly implementing above step for different doping condition, a series of optimized reference parameters can be obtained. The home institute IFSW has equipped the fiber manufacturing facility à ¢Ã¢â€š ¬Ã¢â‚¬Å" consisting of a modified chemical vapor deposition (MCVD) preform production lathe and the new commissioned drawing tower. The prototype of the proposed double-clad MFC fiber will be produced in the IFSW by the stack and draw technique. Investigation on the Laser Architectures The mode field mismatch and high operation power set the obstacles on employing the state of art fiber communication components in the high power laser architecture. Beside that some of critical components for high laser, such Bragg gratings in the LMA cores, large mode area pump coupler or combiner for high power diode are still in the initial stages. Above aspects cause the architecture for the exited high power laser is limited comparing with well developed communication band fiber laser. Most of the previous research on increasing the output power focused on developing the LMA fiber. As the difficulty of increasing the output power by enlarging the mode field is increasing continuously, it is time to consider improve the laser output from other aspect. The high brightness power scalable thin disk laser acting as the in-band pumping source can generate less quantum defect heat than 9ÃÆ'—ÃÆ'—nm laser diode, providing the potential to developing novel or improving existed laser structure by using components which are thermal damage or degradation sensitive. Thus there are rooms to increase the output power or improve the efficiency by developing the laser architecture with thin disk laser and special designed high power components. One of proposed architecture improvements is to replace the butt-coupled HR-mirror in the existed laser with the Bragg grating in the core of the double cladding fiber. Fig 6 (a) the butt-coupling mirror based laser architecture Fig 6 (b) the FBG based laser architecture FBG1,2 reflectors for the laser radiation; FBG3 reflectors for the pump light; The reflection rate of the FBG1 is around 99%, that of FBG2is around 50%. For the butt-coupled mirror based laser architecture (Fig 6 (a)), as the butt-coupled mirror will reflect both the pump light and the laser radiation on a very small area, the energy densities will be extremely high in core and cladding near the conjunct point. To withstand such high power densities, special material substrate such as the sapphire is needed to remove the heat very quickly. Even though, the core power density is still close to the damage threshold of the mirror coating. Furthermore, as the pump wavelength is closed to the laser radiation wavelength, to fabricate the dichroic mirror will be rather difficult. Although the Bragg grating inside the fiber core still has the problem of thermal damage, the damage threshold of FBG will be higher than mirror face. Considerable power increasing is expected for replaying mirror with the Bragg grating. From the aspect of fabrication, the wavelength of the Bragg grating is determined by the mask period and the refraction index of the fiber core, it will be easy to fabricate two FBG with spectrum interval larger than 4nm, which is enough to separate the in band pump light and laser radiation. Finally the FBG also can provide the facility to control the laser wavelength, and the laser output wavelength will be determined by the corresponded reflector. In fig 6 they are FBG1,2. Fig 7 the proposed hybrid laser architecture DMCF: doped multicore double cladding fiber, SMF: single-mode fiber, PMSF: polarization maintained single mode fiber ISO1: polarization dependent optical isolator, Amp: amplifier, DM: dichroic mirror, BS: beam splitter,Li (i = [1; 5]): plus lenses, FBG1: fiber Bragg grating for laser radiation, FBG2: fiber Bragg grating for pump light, PZT: Piezoelectric Ceramics Limited by components, many well developed communication fiber laser techniques such as wavelength tuning and polarization stabilizing cannot be projected to high power fiber laser area directly. A promising method to solve the problem is to develop hybrid architecture which employs a low power single mode fiber feedback loop to control the high power laser. By applying the advanced communication laser techniques in the single mode feedback loop, the high power fiber laser with wavelength tuning and polarization stabilizing can be realized. The proposed hybrid laser architecture with wavelength tuning and polarization stabilizing is shown in fig 7. The thin disk emitted pump light is coupled to the double cladding fiber with a dichroic mirror and a plus lens. The FBG in pump wavelength is employed in the far end of the active fiber. A small part of the emitted beam is reflected and coupled to the feedback loop whereas the most of power is coupled out from the laser cavity. The lens set (L4 to L6) constitutes a free-space imaging system for projecting the far field of the DMCF onto the input face of the SMF. Polarization independent optical isolators and circulator in the feedback loop determined the light traveling direction and eliminated the unwanted reflected light. Furthermore, the polarization independent optical isolator shapes the light to single polarization state, which will be persevered in the feedback loop by polarization maintained fiber. The FBG1 is fixed in a stretch preloaded piezoelectric ceramics, and the reflected wavelength can be tuned slightly by driving the PZT with Bi-directional signal. After passing th e feed pack fiber, the DMCF will amplify the seed laser radiation, and consequently power will be scaled and the polarization can be preserved.

Saying There Is and There Are in Spanish

It is often said that there is or there are is expressed in Spanish using the verb hay (a form of haber) — and indeed that is usually so. However, there are some instances where forms of the verb estar — typically està ¡ (singular) or està ¡n (plural) — should be used. The difference is one in meaning: Hay is used to refer to mere existence.Està ¡ or està ¡n is used when describing a location. As an example, examine this simple sentence: There is a book. At least in writing, the English is ambiguous — the sentence could be phrased as a book is there, meaning that a book is in a certain location. Or could be interpreted as A book exists. In Spanish a different verb would be used for each interpretation. To say that the book is in a location, use a form of estar: El libro està ¡ allà ­. (The book is there.)But to say it merely exists, use a form of haber, in this case hay: Hay un libro. (A book exists.) Eliminating Ambiguity in Translating There The same principle applies in many other cases where the English might be ambiguous: No hay dinero. (There isnt any money, because it doesnt exist.) El dinero no està ¡. (The money exists, but its not here.)No hay profesor. (Theres no teacher, meaning, for instance, that one hasnt been hired.) El profesor no està ¡. (Theres a teacher, but the teacher isnt here.)Hay dos escuelas. (There are two schools, that is, two schools exist.) Dos escuelas està ¡n allà ­. (There are two schools, meaning, two schools are in the direction that is being pointed to.)Hay vacas en Argentina. (There are cows in Argentina.) Las vacas està ¡n en Argentina. (The specific cows are there, in Argentina.)Sà ³lo hay una cosa importante. (There is only one important thing.) La cosa importante està ¡ en otro lado. (The important thing is on the other side. Here cosa refers to a specific object.) Abstract nouns, or nouns that dont refer to an object that can exist in a specific location, normally are not used with estar, but with hay: Hay muchos problemas. (There are many problems.)No hay felicidad sin amor. (There is no happiness without love.)Hay un montà ³n de cosas que quiero decirte. (There is a pile of things I want to say to you.)Hay dos tipos de dolor: el que te lastima y el que te cambia. (There are two kinds of pain: the kind that  hurts you and the kind that changes you.) Another way of understanding the differences involves looking the grammar of the English being translated. In sentences there is is translated using estar, there is functioning as an adverb of location. If here can be substituted for there and the sentence still makes sense, there is being used for location. However, when there is being used as a dummy word, haber is used in translation. Estar vs. Haber in Other Tenses Although examples in the present indicative tense were used above, the same rules apply in other tenses and in the subjunctive mood. Fui a su casa, pero no estaba. (I went to her house, but she wasnt there.)No habà ­a transportacià ³n porque no comprà © un coche. (There was no transportation because I didnt buy a car.)Si hubiera unicornios, la gente los verà ­an. (If there were unicorns, people would see them.)Quiero que haya paz en el mundo. (I want there to be peace in the world.)No quiero que à ©l està © allà ­. (I dont want him to be there.) A Similar Use of Ser When it is used to indicate mere existence, haber can be used only in the third person in standard Spanish. It is often possible to use ser in a similar way in the first- and second-person plural (we and you, respectively). This use is especially common with numbers. Somos seis. (There are six of us.)Ya somos veinte en la clase. (Now there are 20 of us in the class.)Son ustedes cinco hombres. (There are five of you men.)Si sois siete, te ruego que me digas  ¿cà ³mo puede ser? (If there are seven of you, I beg that you tell me, how this can be?) Key Takeaways Although forms of estar and haber can be used in translating there is and there are, their meanings are not the same.Estar is used when suggesting existence in a location, while haber is used in referring to mere existence.Haber also is used with abstract nouns, which dont refer to objects.

The Organizational Culture On Workplace Productivity And...

Business in the 21st century necessitates the exploration of global markets, and employing multicultural teams in order to accomplish corporate goals. This realization has prompted many companies to seek expansion internationally. To remain competitive, the leadership of a U.S. corporation has employed me as a consultant to lead a team to expand their operations in Greece, Germany, Iran, and Singapore. As this expansion unfolds, I would form a culturally diverse leadership team, with the purpose of developing culturally appropriate groups to carry out the expansion goals in these markets. In order to develop a successful global team, I must scrutinize the organizational culture, the necessary leadership style, the impact of the group’s culture on workplace productivity, and the overall impact on the organization itself. Cultural Assessment Since the expansion effort includes several different cultural norms, the leadership team must both recognize these unique characteristics and employ their strengths. Utilizing the GLOBE values for societal practices as measured on a seven-point scale, the team can gain valuable insight for assessing these characteristics strengths. For example, Iran scored the highest Power Distance value (5.43), however this societal practice has the closest range of scores amongst the ones listed, with Singapore scoring the lowest value (4.99), for a difference of 0.44 (House, Hangus, Javidan, Dorfman, and Gupta, 2004).

The Most Painful and Hardest Thing I Ever Had to Do.

The Most Painful amp; Hardest Thing I Ever had To Do. Life is full of pain, sorrow and difficulties. Everyone has experienced something very painful at one time in their life. What was the hardest thing was in my life? I asked the question to myself? Nothing in particular came to my mind, but what do I feel when thinking about† the hardest thing and painful† that I never can forget? Sadness and depression comes to mind. Do you know how it feels to lose someone whom we love the most and are very close to us? I know. My Grandma passed away two years ago. One early morning, while we were sleeping, I received a phone call from India (my native country), and I was informed that I had lost my grandma forever. She died of a heart attack.†¦show more content†¦Ã¢â‚¬ , all kind of questions and lots of advice! There was a time when I thought why does she tell me things over amp; over? It was so annoying sometimes and I also got mad a few times at her. I did try to explain her that I am not a kid anymore, but it never worked! She always kept worrying about me even after I got married and I was a mother of two girls. Why because she loved and cared about me very much. Nobody pretends to know what is ahead of them in life. Sometimes out of the blue a tragedy may strike anyone. That was the first time I had to deal with the experience of death. It hit me in a way I had never felt before. For the first month after her death I felt so lonely. I could not believe that I would never get to see her again. At that moment I understood what death really meant. It steals the life out of someone’s body and we will never see them again. All we have left are just memories. We can remember the best moments spent together. I will always cherish all the memories which was the best part of my life. And always be thankful of her because she raised me to be a better person. She was a strong, loving, and caring woman and had many things to give to others. Years passed, and the grief became a dull ache instead of a heart wrenching pain. The ache began to fade. Life began to brighten again, and we were able to move on, carrying the memory of our beloved one with us.

Public Integrity Auditing and Dynamic †Free Samples to Students

Question: Discuss about the Public Integrity Auditing and Dynamic. Answer: Introduction: The case study is about accounting firm in Australia that is Miller Yates Howarth having office throughout regional centres of NSW and Queensland. Various audit clients of organisation includes mining, agriculture, property and manufacturing industries. One of the most long-standing and significant client of accounting firm is Morgan Fertilizers Pty limited having their operations in Toowoomba, Tamworth and Bathurst in Queensland and NSW. Manager in the audit division that is Jaqui of Miller Yates Howarth is concerned about waste management contractor with Dumparound limited that is investigated by local council regarding their toxic waste. However, the manager is mainly concerned about the contract between waste management company and Morgan Fertilizers Pty. Some of the other issues that Jacqui is concerned about is valuation of inventories. Miller Yates verified stock of Morgan and valuation done by management was accepted by auditing company that did not take into account of subst antial obsolescence (Acito et al., 2013). The major issue identified with valuation of inventories is that cost should be recognized as assets and forwarded until revenue recognition. As per the Australian accounting standard board, inventories are required to be measured at cost or net realizable value, whichever is lower. Inventories cost involves conversion cost, asset cost and any other costs that is incurred on making the asset ready for use. If the part of inventories are damaged then it is not possible to recover the cost of inventories. On other hand, if there is expansion of estimated expenses to make sales, it is not possible to recover cost of inventories. A logical seven step process is suggested by American Association model that takes into account all the ethical issues What are the facts of given case? Model is initiated with step 1 that helps inn establishing the facts of case. Under this step, there is initiation of decision-making process that does not leads to any ambiguity under the case scenario. The fact of case scenario is that engagement of its audit client that is Morgan Fertilizers with waste management contractor, Dumparound limited does not takes into account the specification of damagers that is not signed by later henceforth. Dumparound has been inspected for its toxic disposal of waste that would be damaging environment. This particular aspect regarding contract with waste management organization is inspected and they are concern whether they should interfere and give suggestions relating to their clients business management. In second step, identification of the ethical issues of the given case is done. . Ethical issue in the given case is that whether the audit firm should interfere with the business management of Morgan fertilizers and raise concern for environmental issues hampering communities resulting from waste disposal. If the audit firm does not raises the concern regarding waste disposal and their client contract with Dumparound Limited, then they would be negligent of their professional duties. This is of fact that other entities dealing with Morgan fertilizer would be completely dependant upon the opinion formed by the auditing firm. In the given case, takeover of Morgan fertilizers by oasis Ltd In third step, principles, norms and values related to case is identified. It incorporates decision placement in context of ethical, professional and social behaviour. Values, principles and norms regards that auditors are assumed to have impeccable integrity and assurance that MHY is providing true and fair view of financial situation of Morgan fertilizers while conducting audit. Auditor fails to oblige with their duties concerning stakeholders when they are involved in act of something that interferes with their objectivity. What are alternative course of actions? Alternative course of action is identified in fourth step. First option is that auditing firm should not interfere with business management and continues to carry out audit whether they are being professional on their part and maintains integrity. Second option is to interfere with the business management that their contract with Dumparound limited is not feasible and taking steps accordingly. In next step, it is possible for analyst to depict options that are in accordance with norms or not. Course of action that would be consistent with principles, norms and values is to raise concern about Morgan fertilizer contract with Dumparound limited, as going against environment community work would be unethical on their part (Louwers et al., 2016). Sixth step deals with consequences of outcomes and finally decision is taken in last step. Under option one, auditor would not raise concern about environmental issues and thereby exposing MHY to risk of being in legal and professional trouble (William et al., 2016). This would happen when take over firm that is Oasis ltd would discover the matter. When auditing firm would go for selecting other option, they would present true and fair view of Morgan fertilizes activities along with their financial declaration. However, this would result in creating number of unfortunate consequences on part of their clients and might hamper the operations of business. It would also affect the relationship between auditing firm and clients (DeFond Zhang, 2014). Nonetheless, choosing second option would help in maintaining the confidence of public in audit, enhancing the reputation and social standing of auditors and serving the stakeholders interest. The ethical decision concerning the case is choosing second option. Therefore, auditing firm should raise concern about business management. Report for managing partners of MYZ considering negligence case strength that might be brought by Oasis Ltd: Oasis Limited successfully overtook Morgan Fertilizers and at that very time they were reported of carrying high inventory value in their audited balance sheet. It was discovered after two months of takeover of Morgan business that there was overvaluation of inventories and there was no claim made by auditor regarding inventory quality. It was mentioned that 50% of inventories was held at Bathurst facility of Morgan fertilizers and there were no existence of inventories. Furthermore, there has been over valuation of inventories by 35% at Tamworth facility (Beasley, 2015). Quantity of stocks held at Tamworth facility was not reported by auditor. It is the duty of management of organization to take into account inventories physical confirmation. Basis of preparation of financial statements needs to be established by developing strategies for checking inventories. In order to tally the stock of physical inventories reported to auditors knowledge, it is required by them to review complete techniques for getting suitable and adequate confirmation. Auditors are required to carry out investigation of inventories and inspecting them by being physically present. They are required to evaluate tool that is set by management for controlling and recording inventories and identifying the dependability and reliability of procedures adopted. Furthermore, for evaluating the adjustments concerning inventories between date of physical count and year, auditors are required to adopt an additional measure and they need to be physically available on optional date. It is essential on part of inspection by auditors that they evaluate inward and out ward movement of stocks of Morgan fertilizers from cut-off date until inventories are counted physically (Yuan Yu, 2015). Auditors should evaluate instruction of management and reviewing on internal control with regard to counting and recounting of stocks, stock sheets, tagging, damage items in inventories and their impact on recoding items in financial statements. Valuation of work in progress, procedures of inventories cut-off and inventories movement. Auditors are obliged to refer to audit reports if they faces difficulties in obtaining sufficient and proper evidence regarding to existence and physical count of inventories. While auditing, auditors are evaluated against the standard that obliges them to have professional judgement and maintain integrity while carrying out audit (Hayes et al., 2014). Oasis ltd can bring out negligence charge for not conducting audit as per auditing standards. Auditors are liable to third parties if following points are proved: Any act of negligence of part of employees of audit firm Action taken by third party based on audited financial statement Recklessly ignorance of the facts Intentional preparation of financial statements for enabling action by third party. Conclusion: As per the given case, despite correct verification of stock of Morgan fertilizers by MYH, they would be claimed of conducting audit without considering integrity. The reason is attributable to the fact that obsolescence of stock was not considered and auditing firm accepted valuation done by management. It is also evident from the given case study that Morgan fertilizers on MHY to complete audit within one-month period exercised considerable pressure. Furthermore, Oasis Ltd decisions to overtake Morgan fertilizers was based on audited financial statements and opinion of auditors. Hence, after reviewing all the facts, it is certainly possible on part of Oasis to bring negligence charge against audit firm, MYH. Holding MYH for negligence charge is the sole discretion of court.
