    The aim of this research is to develop realistic models of aerodynamic cross-coupling e ects that can be incorporated in real-time or near real-time simulations of Unmanned Aerial Vehicles (UAVs) in close formation flight. These would permit the assessment of the risks and issues associated with wake vortex evolution and encounter and the analysis of their consequences on the design of automatic control systems and the development of safe and reliable operating procedures. A number of wake vortex modelling techniques that can be used in formation flight simulations are reviewed. A novel Wake Vortex Model (WVM) is developed, implemented, verified, validated and successfully integrated within a Matlab/Simulink simulation environment. The code, named ELL because it is based on Weissinger’s extended lifting line theory, meets the following requirements: (i) it is generic and can easily be adapted to accomodate any wing planform and air vehicle configuration; (ii) it is computationally rapid enough to be used in real-time or near real-time simulations; (iii) and it is sufficiently representative to support studies of aerodynamic interaction between multiple air vehicles during formation reconfiguration and air-to-air refuelling simulations. Simulink test scenarios of two Aerosonde UAVs are developed to test and validate the use of ELL within simulation models, and the simulation environment is interfaced with visualisation tools in order to facilitate the evaluation of multiple air vehicle dynamic interaction

Firstly the concept is discussed and the meaning of the concept coming from certification is clarified then the term is emphasized and the terms which are meeting the responsibilities created by certification are determined. As the profession of certified public accountancy is a kind of self-employment, the similarities and differences between its responsibilities and the other self-employments’ are examined in details. These examined professions are the professions of a lawyer, a doctor, an architect and a building contractor. In the continuation of the work, short histories of some certified public accountants from Turkey, America, England, Germany and France are investigated. Afterwards the law system of public accountancy is taken as a subject in a general way and then is considered at length. All of these are forming the first part of the dissertation. In the second part of the dissertation the legal basis of certified public accountants’ responsibilities stemming from certification is investigated. All laws about ‘independent accountancy’, and ‘certified public accountancy’ –especially the certified public accountants’ responsibilities, coming from certification, in the investigation of the regulations, notifications and civil jurisdictions about the law numbered as 3568 and the two-hundred twenty-seventh clause of tax procedure law- are explicated, the differences in laws, regulations and notifications are displayed, the differences in civil jurisdictions are analyzed. Furthermore in this part Ministry of Finance’s operation upon the professional law is revealed and TURMOB’s works realized after its establishment are studied. In the and third part, re-construction of certified public accountants’ responsibilities derived from certification and the responsibility in the Code of Obligations are dealt with. Besides it is manifested that the responsibility of certified public accountants will concern with either their professional care or their professional faults; and any behavior excluding this is not going to be proper to the fair judgment and positive la

    In this study, the road surface irregularities (pits, bumps, holes, speed breakers, etc.) is intended to be detected and identified with a system to be placed on the vehicles. For this purpose; a vibration-sensitive system is designed consisting of sensors, processor, and GPS receiver as hardware and the algorithms to be used for analyzing the obtained data. With the use of 3-dimensional acceleration sensors in the system, the measurements at the vehicles (vehicle speed/acceleration, the severity of the concussion and location information) are transferred to a database and then the resulting data are analyzed. Exact locations of pits and bumps are determined and their magnitudes are estimated

    The economic impact of military expenditures

    Get PDF
    The author addresses three questions about military spending in developing countries: What are the levels of (and trends in) military spending as a percentage of gross national product? What impact does peacetime military spending have on growth, government spending on social welfare and infrastructure, and other key economic variables? What major factors influence the level of military spending? The author finds that military spending as a share of GNP generally fell in the 1980s, even in the Middle East and North Africa. The mean level of military expenditure as a share of GNP (MES) was 3.9 percent, well below the peak of 5.3 percent in 1976. In 1989, MES averaged only 2.7 percent in Latin America and 2.0 percent in sub-Saharan Africa - the two regions with the most severe economic problems. He finds no evidence of a negative relationship between military spending as a share of GNP and the peacetime growth rate of developing countries - except where military spending is high. He finds that higher shares of MES are not associated with lower shares of government spending on education, health, and infrastructure. As MES increases, government spending as a share of GNP increases, which allows the level of spending on health, education, and infrastructure to be maintained. The author finds some evidence that increased military spending in the developing countries has a weak negative impact on investment and the balance of trade. He finds no evidence of a statistically significant relationship between military spending and inflation. The most important determinant of peacetime military spending is the spending level of neighboring countries - in other words, the potential external threat. Regional conciliation and disarmament may be an important step toward reduced military spending.Achieving Shared Growth,Economic Growth,Peace&Peacekeeping,Health Monitoring&Evaluation,Economic Theory&Research

    Bio-economic efficiency of creep supplementation of forage legumes or concentrate in pasture-based lamb production system

    No full text
    Supplemental feeding of lambs with forage legumes or grains provides a potential option to increase proportion of prime lambs and profitability in intensive pasture-based lamb production systems. A two-year study in the Central Anatolian Region of Turkey compared the effects of creep grazing/supplementary feeding of either alfalfa, birdsfoot trefoil (BFT), or a feed concentrate on the performance of pasture-fed suckling lambs and their dams. The lambs that grazed the base pastures alone without access to any supplemental feeding served as the control group. In both years, creep feeding/grazing commenced in early June following a 42-day pasture grazing period (Period 1) and continued until mid-summer for two separate periods of 21 days each (Periods 2 and 3). Creep supplemented lambs grew faster than those that grazed pasture alone, with no significant difference across all creep supplementation treatments. Across the years, the lambs grew at 229, 222, 219 and 161 g per head d-1 for alfalfa, BFT, concentrate and control groups respectively. None of the lamb feeding strategies affected the performance of ewes. Results from a bio-economic optimization model however showed that supplementing the pasture with BFT and alfalfa in Periods 2 and 3 respectively, maximized economic returns with an extra profit of US$82.22 per lamb above those that grazed the pasture alone

    The Linkages Among Intellectual Capital, Corporate Governance and Corporate Social Responsibility

    No full text
    The purpose of present study is to explore the linkages among Intellectual Capital (IC), Corporate Governance (CG) and Corporate Social Responsibility (CSR) through direct and indirect empirical inquiry. In related literature, IC has been conceptualized within different perspective of assessments. Empirical studies conducted on IC have previously analyzed IC in terms of its measurability and linkage with firm performance. On the other hand, CG and CSR have been evaluated by using their rating value such as CG and/ or CSR Index. Since their importance for all stakeholders became more and more necessary for preventing organization from any types of chaotic environment, there is a need to comprehend their interrelated dynamics. Empirical investigation is conducted on manufacturing firms listed in Istanbul Stock Exchange from 2007 to 2011. Empirical results do support a positive relationship among these important constructs

    Zuhud in Tasawuf as Ethical Bureaucracy to Create Non Corrupted Behavior in Indonesia

    Indonesia is a country that is very large and spacious with a wide variety of cultures and customs vary. A variety of cultures and customs is proof that Indonesia is built with very high ethical values.  Ethics is a reflection of the Indonesian hierarchy of dignity and it should be maintained as a nation's personal identity. Along with the times, ethics comes with a more varied formation. Ethics is also developed in the dynamics of bureaucracy in Indonesia. But, after Indonesia's independence, the more ethical decline, particularly in relation to bureaucracy. To help smooth and in order that the research is comprehensive, the authors used a qualitative research approach as a tool. In addition, in order to balance the research, the author pairs this approach with the type of hermeneutic method, a method that examines the text and studies the behavior of the object. As a result, corrupt behavior becoming into behavior they always do, service to the community to be not optimal, as well as their responsibilities as officers are very low. In this case, I found the application and implementation of the zuhud principles are important in everyday life and/or ethics of their bureaucracy. Zuhud consists of principles of simplicity, integrity, and a strong sense of responsibility when it is done with sincerity and in accordance with the guidance Sharai. However, before the zuhud implemented and applied in bureaucratic ethics and everyday life, first need to be instilled positive attitudes toward zuhud value ​​themselves. Zuhud did not mean anti-world an sich, but the zuhud is able to present a moderate stance between the importance of the world and the hereafter as well
