Modern RF and microwave measurement techniques / edited by Valeria Teppati, ETH Zurich, Andrea Ferrero, Politecnico di Torino, Mohamed Sayed, Microwave and Millimeter Wave Solutions.
No full textengineering bookfair2015Includes bibliographical references and index.xxv, 447 pages :"This comprehensive, hands-on review of the most up-to-date techniques in RF and microwave measurement combines microwave circuit theory and metrology, in-depth analysis of advanced modern instrumentation, methods and systems, and practical advice for professional RF and microwave engineers and researchers. Topics covered include microwave instrumentation, such as network analysers, real-time spectrum analysis, sampling oscilloscopes and microwave synthesizers; linear measurements, such as VNA calibrations, noise figure measurements, time domain reflectometry and dielectric measurements; and non-linear measurements, such as load- and source-pull techniques, broadband signal measurements, and non-linear NVAs. Each technique is discussed in detail, and accompanied by state-of-the-art solutions to the unique technical challenges associated with its deployment. With each chapter delivered by internationally recognised experts in the field, this is an invaluable resource for researchers and professionals involved with microwave measurements"-- Provided by publisher
Double actuated planar single legged hopping robot forward speed and hopping height control
No full textThis paper shows a control method for controlling the forward speed and hopping height of a double actuated planar single legged hopping robot (SLHR).A full representation of the SLHR dynamic performance under the effect of its passive components within appropriate selected initial conditions is shown as the paper discusses the steps for selecting these initial values based on simple ballistic equations. Two types of control algorithms are used to control both actuated robot joints. First a PD control algorithm is tuned to force the hip revolute joint to track the desired trajectory which is related directly to the robots forward speed. Second an energy based controller is introduced to control the knee joint providing the thrust force for the robot to reach its desired apex height. The paper shows a robot good dynamic performance at its different operation modes

A Proposed Data Mining Technique to Improve Decision Support System in an Uncertain Situation
No full textDecision Support System (DSS) is equivalent synonym as management information systems (MIS). Most of imported data are being used in solutions like data mining (DM). Decision supporting systems include also decisions made upon individual data from external sources, management feeling, and various other data sources not included in business intelligence. Successfully supporting managerial decision-making is critically dependent upon the availability of integrated, high quality information organized and presented in a timely and easily understood manner. Data mining have emerged to meet this need. They serve as an integrated repository for internal and external data-intelligence critical to understanding and evaluating the business within its
environmental context. With the addition of models, analytic tools, and user interfaces, they have the potential to provide actionable information that supports effective problem and opportunity identification, critical decision-making, and strategy formulation, implementation, and evaluation. The proposed system will support top level management to make a good decision in any time under any uncertain environment

نموذج مقترح لقرارات هيكل رأس المال للشركات الصغيرة والمتوسطة الحجم في الدول النامية " دراسة تطبيقية في مصر"
No full textThe Purpose of this thesis is to contribute to the limited research of determining the factors that affect the capital structure decisions of the Egyptian small and medium enterprises. Although the traditional theories of capital structure are useful in explaining the capital structure decisions of the companies, but it is showed that they mainly explained these decisions of large enterprises in developed economies, so the researcher tries to specify the main determinants of capital structure of SMEs in the Egyptian context. The study has been performed by investigating the capital structure of a sample of 27 SMEs that are listed in the NileX index, the only index for the Egyptian SMEs. The data was collected over the period 2010 – 2016. The results showed evidence that some of managerial attitudes and characteristics are considered from the drivers of the capital structure decisions of the Egyptian SMEs. Aversion to external control has a negative impact on the willingness to seek external financing while managerial growth intentions and strength of the managerial relationships with others positively affect the leverage. Also, the results showed a limited evidence on the effect of corporate governance mechanisms on the capital structure, CEO duality positively affect the leverage. Firm specific factors and country specific factors are considered from the determinants of the capital structure decisions of the Egyptian SMEs.Under the supervision of:

China goes global : the partial power / David Shambaugh.
No full texteconomic&political bookfair2016Includes bibliographical references (p. 319-381) and index.xvi, 409 p. ;"Most global citizens are well aware of the explosive growth of the Chinese economy. Indeed, China has famously become the "workshop of the world." Yet, while China watchers have shed much light on the country's internal dynamics--China's politics, its vast social changes, and its economic development--few have focused on how this increasingly powerful nation has become more active and assertive throughout the world. In China Goes Global, eminent China scholar David Shambaugh delivers the book that the world has been waiting for--a sweeping account of China's growing prominence on the international stage. Thirty years ago, China's role in global affairs beyond its immediate East Asian periphery was decidedly minor and it had little geostrategic power. As Shambaugh charts, though, China's expanding economic power has allowed it to extend its reach virtually everywhere--from mineral mines in Africa, to currency markets in the West, to oilfields in the Middle East, to agribusiness in Latin America, to the factories of East Asia. Shambaugh offers an enlightening look into the manifestations of China's global ambitions: its extensive commercial footprint, its growing military power, its increasing cultural influence or "soft power," its diplomatic activity, and its new prominence in global governance institutions. But Shambaugh is no alarmist. In this balanced and well-researched volume, he argues that China's global presence is more broad than deep and that China still lacks the influence befitting a major world power--what he terms a "partial power." He draws on his decades of China-watching and his deep knowledge of the subject, and exploits a wide variety of previously untapped sources, to shed valuable light on China's current and future roles in world affairs"-- Provided by publisher."In China Goes Global, eminent China scholar David Shambaugh delivers the book that the world has been waiting for--a sweeping account of China's growing prominence on the international stage.
