Willow Garage - Essay Example Among the positive values that other companies should emulate is sharing information as well as not concentrating on monetary gains. This way such companies remain productive and relevant, which in turn increases their consumer base relating to more profits. There is a common clichà © that knowledge is power, and information not shared is useless. This, in my opinion, is the light that guided the Willow Garage in its endeavors. The company availed ROS, which was associated with a library of information and tools that equip other researchers with the necessary software needed to develop robot applications. In addition, ROS also provided visualizers, device drivers, package management and message-passing that facilitated engineers’ understanding of video, 3D data and camera (Tobe, 2011). By availing this information, other robotics researchers are able to build off from the company’s foundation, as opposed to starting their research work afresh (Ashlee, 2014). In so doing, Willow garage emerges as the greater party compared to other companies. This is because it shares its findings with the world. In other words, it is more concerned with the advancement of robotics for the benefit of the world than building its own name. F urthermore, the work of the company is not lost as other researchers carry on with it. Similarly, companies should share their work and findings with others so that in the occurrence of any event leading to shutting down of the company, others can continue their legacy. Most businesses are profit-oriented. Because of this, most of their dealings are quantitative as opposed to qualitative. Such businesses do not care much about quality of their products and services. Moreover, their dealings are often confidential so that their competitors do not get wind of their work. In cases where they avail some of their information, there is always a cost involved. This is contrary to Willow Garage’s

The Prefabricated Houses Term Paper Example | Topics and Well Written Essays - 3750 words

The Prefabricated Houses - Term Paper Example One of these types of buildings is known as "prefabricated house" that kind of housing can be finished in short period and manufactured off-site in advance. It consists of standard sections that can be easily shipped, assembled, and dis-assembled. Moreover, the cost of  prefabricated  unit  is equivalent to  30-40%  of the cost of typical unit. This paper explores prefabricated housing, benefits, types, installation procedure, misconceptions, and future prospects. Prefabricated Houses Defined Prefabrication is a process of assembling the components of a particular structure in a factory and transporting the finished assemblies or sub-assemblies to the construction site where the final product is to be installed. The process is an alternative to the traditional on-site construction practice where raw material is gathered and assembled on location of construction (Daab, 2008). The primary principle of prefabrication is grouping comparable construction tasks and applying assem bly line techniques on construction site where skilled labor is available. The process is also called off-site manufacture (OSM). The practice is more effective when modularization is also employed, that is, the process of repeating units of form throughout the structure, or when several replica of the same basic structure are to be built (West 1). According to Callcutt Review of House building Delivery (2007) prefabrication is time-saving, economical, and provide high quality end product. In addition, the process has a potential to offer faster construction, cleaner and safer working conditions, reduced housing faults, reduced construction waste, and more energy efficient homes. On the other hand, some of the challenges of prefabricated housing include: interface detailing, handling and supply chain logistics, transportation to location, investment ability, and social stigma (West 1).Schweitzer and Michael state: "The earliest known examples of successful prefabricated housing in A merica came soon after, however, the "great house" of Edward Winslow was sent from England to Cape Ann northeast of Boston in 1624 to provide for the fishing fleet already operating there. The building was reportedly moved several times subsequently and parts of its supposedly were built into a house in Salem, Massachusetts, still standing today, more than 300 years later."(57) Types of Prefabricated Housing According to BRE and UK Department for Communities and Local Government (Callcutt, 2007) there are three types of prefabricated systems used by housing market. It includes volumetric systems, partial modularization, and prefabrication of elements. Volumetric systems include completely assembled three-dimensional modular units manufactured in a factory and installed on location. Partial modularization includes standardized units or elements while prefabrication of elements refers to an assortment of individual systems including 'frames' and 'structural insulated panels (SIP)'.Eac h of these systems has its own pros and cons, however, all of these are important for prefabricated housing market because of their use in isolation or combination as hybrid techniques(Callcutts,2007). Three types of prefabricated housing market sections include modular, penalized, and precut. A modular home system consists of three-dimensional unit. It includes interior and exterior walls, plumbing, wiring, and other kinds of utility

Vocabulary Parent Letter Essay Example for Free

Vocabulary Parent Letter Essay Vocabulary words and knowledge are critical in reading comprehension and vitally important that new and young readers develop a large ‘word bank’ and effective vocabulary learning strategies. That being said, we will have an emphasis on vocabulary words in our classroom this year. There are several effective vocabulary learning strategies that we will be using in the classroom, I encourage you to employ these strategies at home assisting in the reading comprehension and vocabulary development of your young reader. Effective Vocabulary Learning Strategies: †¢Pre-teaching Vocabulary Word – teaching your child unfamiliar words prior to the reading experience. An adult should preview the reading material determine unfamiliar words then define and discuss the words. This provides understanding of the word for the child as well as establishing connotation. It also gives the adult feedback on how well the child understands the word. †¢Repeated Exposure to Words – The more we are exposed to a word, the stronger our understanding become. A child needs to hear and use a word several times before it becomes part of their vocabulary. Provide multiple opportunities for the child to use a new word in written and spoken form. †¢Keyword Method – Like pre-teaching, the keyword method rather than having a child remember the definition, it encourages the adult to give a ‘word clue’ to help them understand the word. The idea behind the keyword method is to create an easy cognitive link to the word’s meaning that the reader can access efficiently during a reading experience. †¢Root Analysis – Many English words are derived from Latin or Greek roots. They contain a ‘core’ root or use prefixes or suffixes. Adults, when working with the student should focus on the commonly occurring roots, prefixes and suffixes. When a reader is able to break down unfamiliar words into their prefixes, suffixes and roots they can begin to determine their meanings. †¢Restructuring Reading Material – This strategy is particularly effective for struggling readers improving their vocabulary. Sometimes grade level materials contain too many unfamiliar words. Adults can restructure the material. Portions of the difficult words can be replaced with ‘easier’ synonyms to help the reader understand the overall text. Also, particularly challenging words can easily be ‘looked up’ while reading the text. Taking a few minutes to read with your child, using these strategies will truly aid their vocabulary development and reading comprehension for years to come. Let’s work together as a team to ensure that your child becomes an independent, lifelong learner.

Dispersion Properties of the Propagation of Linear Waves

Dispersion Properties of the Propagation of Linear Waves ABSTRACT In electron-positron plasmas some of the plasma modes are decoupled due to the equal charge to mass ratio of both species. The dispersion properties of the propagation of linear waves in degenerate electron–positron magnetoplasma are investigated. By using the quantum hydrodynamic equations with magnetic fields of the Wigner–Maxwell system, we have obtained a set of new dispersion relations in which ions’ motions are not considered. The general dielectric tensor is derived using the electron and positron densities and its momentum response to the quantum effects due to Bohm potential and the statistical effect of Femi temperature. It has been demonstrated the importance of magnetic field and its role with the quantum effects in these plasmas which support the propagation of electromagnetic linear waves. Besides, the dispersion relations in case of parallel and perpendicular modes are investigated for different positron-electron density ratios. Keywords: Quantum Plasma; Dispersion relation ; Electron –Positron 1- INTRODUCTION Electron-positron (e-p) plasmas are found in the early universe, in astrophysical objects (e.g., pulsars, super nova remnants, and active galactic nuclei, in ÃŽ ³ -ray bursts, and at the center of the Milky Way galaxy [1]. In such physical systems, the e-p pairs can be created by collisions between particles that are accelerated by electromagnetic and electrostatic waves and/or by gravitational forces. Intense laser-plasma interaction experiments have reported the production of MeV electrons and conclusive evidence of positron production via electron collisions. Positrons have also been created in post disruption plasmas in large tokamaks through collisions between MeV electrons and thermal particles. The progress in the production of positron plasmas of the past two decades makes it possible to consider laboratory experiments on e-p plasmas [2]. The earlier theoretical studies on linear waves in electron–positron plasmas have largely focused on the relativistic regime relevant to astrophysical contexts [3]. This is largely due to the fact that the production of these electron–positron pairs requires high-energy processes. In laboratory plasmas non-relativistic electron–positron plasmas can be created by using two different schemes. In one scheme, a relativistic electron beam when impinges on high Z-target produces positrons in abundance. The relativistic pair of electrons and positrons is then trapped in a magnetic mirror and cools down rapidly by radiation, thus producing non-relativistic pair plasmas. In another scheme positrons can be accumulated from a radioactive source. Such non-relativistic electron–positron plasmas have been produced in the laboratory by many researchers. This has given an impetus to many theoretical works on non-relativistic electron–positron plasmas. Stewart and Laing [4] studied the dispersion properties of linear waves in equal-mass plasmas and found that due to the special symmetry of such plasmas, well known phenomena such as Faraday rotation and whistler wave modes disappear. Iwamoto [5] studied the collective modes in non-relativistic electron–positron plasmas using the kinetic approach. He found that the dispersion relations for longitudinal modes in electron–positron plasma for both unmagnetized and magnetized electron–positron plasmas were similar to the modes in one-component electron or electron–ion plasmas. The transverse modes for the unmagnetized case were also found to be similar. However, the transverse modes in the presence of a magnetic field were found to be different from those in electron–ion plasmas. Studies of wave propagation in electron–positron plasmas contin ue to highlight the role played by the equal mass of electrons and positrons. For example, the low frequency ion acoustic wave, a feature of electron–ion plasmas due to significantly different masses of electrons and ions, has no counterpart in electron–positron plasma. Shukla et al [6] derived a new dispersion relation for low-frequency electrostatic waves in strongly magnetized non-uniform electron–positron plasma. They showed that the dispersion relation admits a new purely growing instability in the presence of equilibrium density and magnetic field inhomogeneties. Linear electrostatic waves in a magnetized four-component, two-temperature electron–positron plasma are investigated by Lazarus et al in Ref. [7]. They have derived a linear dispersion relation for electrostatic waves for the model and analyzed for different wave modes. Dispersion characteristics of these modes at different propagation angles are studied numerically. In this work, The dispersion properties of the propagation of linear waves in degenerate electron–positron magnetoplasma are investigated. By using the quantum hydrodynamic equations with magnetic fields of the Wigner–Maxwell system, we have obtained a set of new dispersion relations in which ions’ motions are not considered. The general dielectric tensor is derived using the electron and positron densities and its momentum response to the quantum effects due to Bohm potential and the statistical effect of Femi temperature. 2- MODELING EQUATIONS We consider quantum plasma composed of electrons and positrons whose background stationary ions. The plasma is immersed in an external magnetic field . The quasi-neutrality condition reads as . From model, the dynamics of these particles are governed by the following continuity equation and the momentum equation: (1) (2) Here and are the number density, the velocity and the mass of particle respectively () and is the plank constant divided by. Let electrons and positrons obey the following pressure law: Where, is the Fermi thermal speed, is the particle Fermi temperature, is the Boltzmann’s constant and is the equilibrium particle number density. We have included both the quantum statistical effects through Fermi temperature and the quantum diffraction in the –dependent. If we set equal to zero and equal the temperature of electrons and positrons, we obtain the classical hydrodynamic equation. Assuming that the plasma is isothermal, the Fermi speeds for different particles may be equal. Using the perturbation technique, assume the quantity representing (n, u, B, E) has the following form where is the unperturbed value and is a small perturbation . Assuming the equilibrium electric field is zero and linearizing the continuity and the momentum equations, we have: (3) (4) Multiplying equation (4) by and Simplifying, we can obtain the following equation: (5) where, , , and Assuming, , then the three components of the fluid velocity can be written as: (6a) (6b) (6c) Where, and The current density and the dielectric permeability of the medium are given: (7) (8) where is the unit tensor. So, we can obtain the dielectric tensor as follows: (9) Where, Then, according to equations (8), (9) The propagation of different electromagnetic linear waves in quantum plasma can be obtained from the following general dispersion relation: (10) Where, is the plasma frequency and . 3- DISCUSSION In this section, we focus our attention on the discussion of some different modes in two cases that the wave vector parallel and perpendicular to the magnetic field . (3.I) Parallel modes So, this case leads to, with . Therefore the general dispersion relation (10) becomes: (11) This gives two dispersion relations. The first one () investigates the dispersion of electrostatic quantum waves included the quantum effects as follows (12) By neglecting the quantum effects, equation (11) describes the following well-known classical modes The second dispersion equation gives: (13) Equation (13) is similar to the dispersion of left and right waves (L- and R- modes). Owing to the symmetry between the positively and negatively charged particles, the dispersion relation for the right circularly polarized wave is identical to the left circularly polarized wave. It has been noted that no quantum effects on these modes. For unmagnetized plasma , the dispersion relation becomes: (14) (3.II) Perpendicular mode In this case, we have So, the general dispersion relation (10) becomes: (15) Where it has the following new elements , , , , , , , In the case of unmagnetized plasma , we have the following two dispersion equations: (16) and (17) The equation (16) is the well known dispersion relation which investigates the propagation of electromagnetic waves in classical unmagnetized plasma.The damping is absent because the phase velocity of the wave obtained from this equation is always greater than the velocity of light, so that no particles can be resonant with the wave. This results is analogous to the one-component electron plasma [5]. While the other relation (17) indicates the dispersion of the waves in electron-positron plasma under the quantum effects. 4- NUMERICAL ANALYSIS AND RESULTS In this section, we are going to investigate the above dispersion relations numerically. Introducing the normalized quantities , , , , and the plasmonic coupling () which describes the ratio of plasmonic energy density to the electron Fermi energy density, we rewrite some of the dispersion relations in both of parallel and perpendicular modes. (4.I) Parallel modes In the first, equation (12), () becomes: (18) Where, . The dispersion relation (17) has two positive solutions, Fig 1, for positron electron density ration with and .One of solutions of the dispersion equation (19) can be investigated in Fig. (2) to study the parallel modes for different density ratios with in quantum plasma . The solution of the normalized dispersion equation (17) has been also displayed in 3D figure (3) for quantum unmagnetized plasma . It is clear from the previous figures that the dispersion relations depend strongly on the density ratio of positron to electron. As the positron density is increased to equal to the electron density, the phase velocity has been increased. In the beginning, with very small positron density the wave frequency equals the electron plasma frequency and decreased with positron density increased. Besides, in the Fig. (4), the dispersion relation of parallel modes is shown for different quantum ratios , in the case of positron-electron density ratio and equal velocities of them . It is clear that the phase velocity of the mode is increased with the increases of plasmonic coupling ratio. (4.II) Perpendicular mode In the case of perpendicular modes, equation (15) can be normalized and solved numerically (here, ). Figure (5) displays the dispersion curves of electromagnetic modes under the effect of different density ratios in classical plasma. Also, the other equation (16) can be solve numerically to give two real solutions. One of them is the same solution approximately of equation (15) (which is clear in Figure (6). The other solution of dispersion equation (16) is displayed in figure (7). It is clear in the figures that the dispersion curves at depend essentially on the positron-electron density ratio . As the positron density increases to equal electron density, the wave frequency is increased to be bigger than the plasma frequency. On the dispersion curves (figures (5) and (6)), it has been noted the phase velocity of modes (+ve slope of the curves) decreases as density ratio increases. But, on the figure (7), the phase velocities of these modes (-ve slope) are the same with changes of the density ratio. They tend to zero with large wave number which means that these modes cannot propagate in plasmas. Figure (8) investigates the dispersion relations of the electromagnetic waves in electron-positron plasma under the quantum effects. It is clear that, in the case of classical plasma, the wave frequency decreases as wave number increases (the phase velocity is negative). But, in the case of quantum plasma (for small ratio ), the wave frequency deceases as wave number increases (the phase velocity is negative). Then, the phase velocity and group velocity tends to zero at definite wave number () depends on the quantum ratio (). For high quantum ratio, the phase velocity starts to be +ve and increases again. 5-CONCLOUSION In this work, The dispersion properties of the propagation of linear waves in degenerate electron–positron magnetoplasma are investigated by using the quantum hydrodynamic equations with magnetic fields of the Wigner–Maxwell system. The general dielectric tensor is derived using the electron and positron densities and its momentum response to the quantum effects due to Bohm potential and the statistical effect of Femi temperature. We have obtained a set of new dispersion relations in two cases that the wave vector parallel or perpendicular to the magnetic field to investigate the linear propagation of different electromagnetic waves. It is clear that the quantum effects increase or decrease the phase velocity of the modes depends on the external magnetic field. Besides, it has shown that the dispersion curves at depend essentially on the positron-electron density ratio such as the positron density is increased to equal electron density, the wave frequency of the modes is increased..

Heineken out of Burma :: essays research papers

Heineken out of Burma The action groups 'A Seed Europe' and the Dutch action group 'XminY' started a campaign in February 1996, called "Heineken out of Burma!". The investment plans of the Dutch brewer Heineken Inc. in Burma (Myanmar), were said to provide material support and legitimacy to the violent dictatory rulers of the country. Heineken sees Burma as an emerging market, that must be entered without delay. Western beer markets are becoming saturated and the potentials for growth in Asia are enormous. Competitors, such as Carlsberg and San Miguel, are likewise turning their investments towards Asia. The political opposition in Burma, lead by Nobel Price laureate Aung San Suu Kyi, calls on foreign companies not to invest in Burma for the time being, however. International embargoes can support the internal opposition against the regime, she says. Heineken has a 42% share in the Asian Pacific Brewery Ltd (APBL). This, in turn, owns 60% of the shares of the Myanmar Brewery Ltd (MBL). The remaining 40% of the shares belong to UMEHL: the Union of Myanmar Economic Holdings Ltd. UMEHL is lead by the military rules of the country. APBL wants to invest 15 million US dollars in a brewery in Burma. That can only be done in the form of a joint-venture with UMEHL. The military rulers force this construction onto APBL. Forty percent of the profits that the brewery will yield in the future will thus flow towards the dictators. Heineken did not deny that the Burmese regime is guilty of gross violations of human rights. On the contrary, Heineken shared the analyses of the action groups and said to be very concerned about the human rights situation in Burma. There is one difference, however: the action groups concluded that Heineken should cancel its investments in Burma, but Heineken did not intend to do so. "We sincerely believe that we can reconcile our policy in Burma with our corporate values and norms", so Heineken's press officer before the Dutch media. The action groups say: "By investing in Burma at this moment, and by embarking on a joint venture with UMEHL, Heineken makes itself an accomplice in the tragedy of the Burmese people". This complicity consists in particular of two points.

Employment Law HRM Strategy Essay

Employment law is critical to an organization allowing it to fulfill needs and business ventures applicable to state and federal laws. In this paper we will be discussing the laws that allow and disallow seasonal employees from another country to be able to work in the state of Georgia. In the paragraphs below I will explain to you the reader the scenario listed above, I will set a plan in accordance to the HRM situation, justify my approach to HR management, state the competitive advantage, and describe the situation that may occur from not properly following the appropriate laws. Everyone has the right to work, and there are many opportunities in this country. In order to enjoy these liberties workers need to be documented in order to be legally able to work without consequence to them, and the company that they are occupying a position. Employment law consists in the body of laws and rules regulating civil rights and non-union related conduct in the workplace (Stewart, 2012). Civil rights include a workplace free from discrimination and harassment for people who fit into one of the legally protected class (Stewart, 2012). Conduct law refers to equal and fair pay immigrant and employment at will laws (Stewart, 2012). These laws are the laws that are pertaining to the laws that are corresponding with the situation of seasonal employees from another country. The Migrant and Seasonal Agricultural Worker Protection Act (MSPA) provides employment-related protections to migrant and seasonal agricultural workers and is administered and enforced by the Wage and Hour Division of the U. S. Department of Labor (DOL,2012). Within the confines of the law I came up with a plan for seasonal workers, first these are the parameters that we must follow. Every non-exempt farm labor contractor, agricultural employer, and agricultural association must: * Disclose the terms and conditions of employment to each migrant worker in writing at the time of recruitment and to each seasonal worker when employment is offered, in writing if requested; * Post information about orker protections at the worksite; * Pay each worker the wages owed when due and provide each with an itemized statement of earnings and deductions; * Ensure that housing, if provided, complies with substantive federal and state safety and health standards; * Ensure that each vehicle, if transportation is provided, meets applicable federal and state safety standards and insurance requirements and that each driver be properly licensed; * Comply with the terms of any working arrangement made with the workers; and * Make and keep payroll records for each employee for three years (DOL. 012) The plan that we will use to manage the situation will be by appointing two or three HR professionals, and a project manager to oversee the project. They will coordinate events as per the MSPA which regulates the seasonal workers. The MSPA requires farm labor contractors, agricultural employers, and agricultural associations, who recruit, solicit, hire, employ, furnish, transport, or house agricultural workers, as well as providers of migrant housing, to meet certain minimum requirements in their dealings with migrant and seasonal agricultural workers (DOL, 2012). Our plan resembles closely to what is already in state as per state, federal and local legislations. Human resource is the greatest asset that any organization possesses and it must ensure that this potential is harnessed to the maximum to contribute positively towards the growth of the organization (Amillionlives, 2010). Every non-exempt farm labor contractor, agricultural and seasonal agricultural association must; disclose the terms and conditions of employment to each migrant worker in writing at the time of recruitment and to each seasonal worker when employment is offered in writing (DOL, 2012). HR management would use this information to aide in writing the offers of employment for the migrant and farm workers. There are many competitive advantages of HRM practices meets the employment laws, typically business are more competitive with a structured HRM practice in place. Having an HRM in place makes it easier to organize employment according to the laws. An effective HRM in a competitive advantage will use information provided from the Department of Labor (DOL), one instance that would be useful in this situation is Employers must provide each migrant and seasonal day-haul worker with a written disclosure at the time of recruitment that describes the terms and conditions of his or her employment. When offering employment, the employer must provide such isclosure to all seasonal workers upon request. The disclosure must be written in the worker’s language. If the HRM is effective they will be able to utilize different commodities of the job in order to provide the service as per employment laws and contract obligations. If the situation of the need for seasonal employees who may be from another country were not to follow proper laws could result in major fines and penalties to the company. Ethics related problems are faced by the organizations whenever there is a practice of using favoritism rather than ability or job performance for managerial decisions regarding employment, promotion, pay and discipline. These problems can be reduced and eliminated by maintaining the highest standards of professional and personal conduct, encouraging employers to make fair and equitable treatment of all. Severe penalties may arise from the state and federal departments for not following proper protocol. Immigration may also be informed of the situation due to the fact that they are dealing with non-citizen workers. In the paragraphs above I have explained to you the reader the scenario of the seasonal workers, provided a plan, justified the approach of HR management, competitive advantage, and provided the consequences that may arise from not following proper laws and protocol.
