Convergence is a topic that many point to as the driving force behind modern product development. The merger of similar devices into a single product form can create a number of advantages for both producers and consumers, but successful design must take more than just this into account. Convergence is the evolution of a product through a disruptive and uncertain environment of technology and user needs. While the digital revolution has certainly been the biggest recent disrupter to society and design, there are signs of convergence in both form and function that have occurred across many products, and product categories. Producers and consumers always clamor for devices that are useful and convenient, take advantage of the latest technologies, and yet remain intuitive, attractive, and easy to use. This paper will dissect the meaning of convergence in product design and provide a framework for understanding and dialog. Combined with an extensive survey and product mapping, this definition will then be used to delineate approaches and principles for the effective design of evolving products in today's changing environment. The findings of this paper will help designers make decisions when considering the trade-offs between aesthetics, functionality, and ease of use in technology based products.

The goal of the Q-weak experiment is to make a measurement of the proton's weak charge ($Q^p_W = 1-4\sin^2\theta_W$) to an accuracy of ~4%. This would represent a ~0.3% determination of the weak mixing angle ($\sin^2\theta_W$) at low energy. The measurement may be used for a precision test of the Standard Model (SM) prediction on the running of $\sin^2\theta_W$ with energy scale. The Q-weak experiment operates at Thomas Jefferson National Accelerator Facility (Jefferson Lab). The experiment determines the proton's weak charge by measuring the parity violating asymmetry in elastic electron-proton scattering at low momentum transfer $Q^2 = 0.026 (GeV/c)^2$ and forward angles (~8 degree). The anticipated size of the asymmetry, based on the SM, is about 230 parts per billion (ppb). With the proposed accuracy, the experiment may probe new physics beyond Standard Model at the TeV scale. This thesis focuses on my contributions to the experiment, including track reconstruction for momentum transfer determination of the scattering process, and the focal plane scanner, a detector I designed and built to measure the flux profile of scattered electrons on the focal plane of the Q-weak spectrometer to assist in the extrapolation of low beam current tracking results to high beam current. Preliminary results from the commissioning and the first run period of the Q-weak experiment are reported and discussed.

The main objective of the study is to analyze the role of family planning program in reducing maternal mortality in Bangladesh. A conceptual framework has been developed in which family planning is shown to be integrated in reducing maternal mortality. This study found that the risk factors of maternal mortality e.g. unwanted pregnancy, high parity, and early and old age at child birth still prevail in Bangladesh. It is hypothesized that the prevalence of these factors can be substantially reduced by a proper practice of family planning. There is a high level of unmet need for family planning Bangladesh, and its removal will substantially help in reducing maternal mortality in the country. The risk factors of maternal mortality are strongly associated with lack of family planning practice and other socio-economic and demographic background characteristics of women. By using data from the Bangladesh Demographic and Health Survey (BDHS) of 2004 and the Bangladesh Maternal Health and Maternal Mortality Survey (BMMS) of 2001 the study has analyzed the relationship of the risk factors of maternal mortality, namely wantedness of pregnancy, age at child birth, parity and birth interval with various socio-demographic factors. The analysis has shown that use status of family planning is influenced by the risk factors of maternal mortality. Wantedness of pregnancy has been found to be significantly related with age at birth, parity and birth interval. It has been also found that the risk factors of maternal mortality also affect on antenatal care. The study has identified some policy implications regarding family planning and maternal mortality, and has made appropriate recommendations. One of the major aspects of the strategies to reduce maternal mortality through family planning is to provide family planning services to all women, regardless of any group affiliation. Fulfilment of unmet for family planning has been recommended as an important strategy to reduce maternal mortality in the country. It addition, it is also recommended to raise the age at marriage and child birth, to space births and to limit family size by empowering women through education.

This thesis deals with the relationship of exchange rate theory regarding the currency pair EUR / USD. The theoretical part defines the fundamental issue of exchange rates, exchange-rate regimes and the foreign exchange market, where the exchange rates are made. The crucial part of the theory is devoted to economic theories causing currency movements. In conclusion of the theoretical part attention is also given to econometric methods and statistics time series analysis. The analytical part of the thesis examines the short and long term relationships of purchasing power parity, the theory of parity of interest rates and monetary approach to the exchange rate for the currency pair EUR / USD. A regression analysis is used for investigating short-term relationships, and is applied to the relative changes in the value of the currency pair EUR / USD and the changes in the relative values of the theory of exchange rate determination. The long-term equilibrium relationship is analyzed by using a cointegration analysis, specifically the Engle-Granger and Johansen tests. The estimated results are evaluated and discussed in the final part of the thesis.

The paper analyses validity of main exchange rate theories in case of the Czech crown. Investigated relationships comprise purchasing power parity, interest rate parity and real interest monetary model. Technical part of the analysis involves cointegration, namely Johansen's method based on vector autoregressive models. Two currency pairs are in the focus: CZK/EUR and CZK/USD. Empirical calculations did not prove the absolute validity of the theories but pointed out to other factors of exchange rate, such as convergence process, impacts on inflation targeting decisions, non-monetarist determinants and the recent financial crisis.

In 1999, France, after a long and dragging debate, revised its Constitution in order to enable the installation of gender quotas in elected political bodies. In 2000 'parity laws' were enacted. They defined the parameters of these quotas that applied strictly to elections of proportional electoral system, such as elections into municipal councils with over 3.500 inhabitants, regional and European elections, and Senate elections in areas with three and more senators. In elections with plurality voting system, such as legislative elections and Senate elections with one or two senators, the parity was supposed to be achieved by imposing of financial penalty for those political parties that would not comply with the parity laws. This diploma thesis describes a public discussion that had taken place in France before the adoption of the gender parity imposed by the law. It compares four major political parties- the Republicans, Socialist party, The Greens and the National Front. The research analyzes their compliance with parity laws and their implementation on their candidate lists in parliamentary as well as Senate elections. The aim of this diploma thesis is to show and compare the rhetoric and the actions of the studied political parties with regards to the parity. The research analyzes the lists of...

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Next generation satellite communication systems require efficient coding schemes that enable high data rates, require low overhead, and have excellent bit error rate performance. A newly rediscovered class of block codes called Low Density Parity Check (LDPC) codes has the potential to revolutionize forward error correction (FEC) because of the very high coding rates. This paper presents a brief overview of LDPC coding and decoding. An LDPC algorithm developed by Goddard Space Flight Center is discussed, and an overview of an accompanying VHDL development by L-3 Communications Cincinnati Electronics is presented.

A large literature has related the failure of interest rate parity in the foreign exchange market to the existence of a time-varying risk premium. Nevertheless, most modern open economy DSGE models imply a (near) perfect interest rate parity condition. This paper presents a stylized two-country incomplete-markets model in which countries have strong precautionary motives because they face international liquidity constraints, the presence of which successfully generates a time-varying risk premium: the country that has accumulated debt after experiencing relative worse times has stronger precautionary motives and its asset carries a risk premium.
