Book Description :

As the Czech ambassador to the United States, H. E. Petr Gandalovic noted in his foreword to this book that Mla Rechcgl has written a monumental work representing a culmination of his life achievement as a historian of Czech America. The Encyclopedia of Bohemian and Czech American Biography is a unique and unparalleled publication. The enormity of this undertaking is reflected in the fact that it covers a universe, starting a few decades after the discovery of the New World, through the escapades and significant contributions of Bohemian Jesuits and Moravian brethren in the seventeenth and eighteenth centuries, the mass migration of the Czechs after the revolutionary year of 1848, and up to the early years of the twentieth century and the influx of refugees from Nazism and communism. The encyclopedia has been planned as a representative, a comprehensive and authoritative reference tool, encompassing over 7,500 biographies. This prodigious and unparalleled encyclopedic vade mecum, reflecting enduring contributions of notable Americans with Czech roots, is not only an invaluable tool for all researchers and students of Czech American history but is also a carte blanche for the Czech Republic, which considers Czech Americans as their own and as a part of its magnificent cultural history.

Book Description :

No comprehensive study has been undertaken about the American learned men and women with Czechoslovak roots. The aim of this work is to correct this glaring deficiency, with the focus on men and women in medicine, applied sciences and engineering. It covers immigration from the period of mass migration and beyond, irrespective whether they were born in their European ancestral homes or whether they have descended from them. This compendium clearly demonstrates the Czech and Slovak immigrants, including Bohemian Jews, have brought to the New World, in these areas, their talents, their ingenuity, the technical skills, their scientific knowhow, as well as their humanistic and spiritual upbringing, reflecting upon the richness of their culture and traditions, developed throughout centuries in their ancestral home. This accounts for their remarkable success and achievements of theses settlers in the New World, transcending through their descendants, as this publication demonstrates. The monograph has been organized into sections by subject areas, i.e., Medicine, Allied Health Sciences and Social Services, Agricultural and Food Science, Earth and Environmental Sciences and Engineering. Each individual entry is usually accompanied with literature, and additional biographical sources for readers who wish to pursue a deeper study. The selection of individuals has been strictly based on geographical vantage, without regards to their native language or ethnical background. Some of the entries may surprise you, because their Czech or Slovak ancestry has not been generally known. What is conspicuous is a large percentage of listed individuals being Jewish, which is a reflection of high-level of education and intellect of Bohemian Jews. A prodigious number of accomplished women in this study is also astounding, considering that, in the 19th century, they rarely had careers and most professions refused entry to them.

Book Description :

This is a comprehensive history of immigrants from the historic lands of the Bohemian Crown and its successor states, including Czechoslovakia and the Czech Republic, based on the painstaking lifetime research of the author. The reader will find lots of new information in this book that is not available elsewhere. The title of the book comes from a popular song of the famous Czech artistic duo, Voskovec and Werich, who described America in those words when they lived here, reflecting on their love for this country. It covers the period starting soon after the discovery of the New World to date. The emphasis is on the US, although Canada and Latin America are also covered. It covers the arrival and the settlement of the immigrants in various states and regions of America, their harsh beginnings, the establishment of their communities, and their organization. A separate section is devoted to the contributions of notable individuals in different areas of human endeavor, including Bohemians, Moravians, Bohemian Jews, and the Slovaks. These people excelled in just about every facet of human undertaking. Even though a total number of these immigrants were fewer than other ethnic groups, their accomplishments were phenomenal. Nothing like this has ever been published since the time Thomas Capek wrote his classic The Cechs (Bohemians) in America some one hundred years ago.

Book Description :

From the authors' abstract: "This analytical study looks at the importance of Deep Space Operations and recommends an approach for senior policy leaders. Section 1 presents a capability requirements definition with candidate solutions and technology strategies. Section 2 recommends an acquisition and organizational approach. Section 3 provides an extended strategic rationale for deep space operations as a national priority." And from the Introduction: [this essay] "presents capability requirements, potential solutions, and strategic rationale for achieving movement and maneuver advantage in deep space. In this context, deep space is anything beyond geosynchronous Earth orbit (GEO). Driving the research are two primary assumptions underpinning the need for investment in deep space propulsion. The first assumption is that growing international activity, commerce, and industry in space extends the global commons, thus creating a military-economic imperative for the United States Department of Defense (DoD) to expand its protection of U.S. interests by defending space lines of communication. Although there are wide-ranging reasons to expand the space-faring capabilities of the human species, from the capitalistic to the existential, the fact of its occurrence offers the U.S. immense strategic opportunity. Section 1, operating on this assumption, recommends capability-based requirements for deep space operations given a projected future operating environment.The second driving assumption underpinning this study is that improved movement and maneuver capabilities in deep space offer a wide array of benefits for the current National Security Enterprise, and for this reason alone demands attention in the form of disciplined investment. Furthermore, because the core functional capability required for deep space operations is in-space propulsion, the requirement necessitates a materiel solution.

Book Description :

Spacecraft Dynamics and Control: The Embedded Model Control Approach provides a uniform and systematic way of approaching space engineering control problems from the standpoint of model-based control, using state-space equations as the key paradigm for simulation, design and implementation. The book introduces the Embedded Model Control methodology for the design and implementation of attitude and orbit control systems. The logic architecture is organized around the embedded model of the spacecraft and its surrounding environment. The model is compelled to include disturbance dynamics as a repository of the uncertainty that the control law must reject to meet attitude and orbit requirements within the uncertainty class. The source of the real-time uncertainty estimation/prediction is the model error signal, as it encodes the residual discrepancies between spacecraft measurements and model output. The embedded model and the uncertainty estimation feedback (noise estimator in the book) constitute the state predictor feeding the control law. Asymptotic pole placement (exploiting the asymptotes of closed-loop transfer functions) is the way to design and tune feedback loops around the embedded model (state predictor, control law, reference generator). The design versus the uncertainty class is driven by analytic stability and performance inequalities. The method is applied to several attitude and orbit control problems. The book begins with an extensive introduction to attitude geometry and algebra and ends with the core themes: state-space dynamics and Embedded Model Control. Fundamentals of orbit, attitude and environment dynamics are treated giving emphasis to state-space formulation, disturbance dynamics, state feedback and prediction, closed-loop stability. Sensors and actuators are treated giving emphasis to their dynamics and modelling of measurement errors. Numerical tables are included and their data employed for numerical simulations. Orbit and attitude control problems of the European GOCE mission are the inspiration of numerical exercises and simulations. The suite of the attitude control modes of a GOCE-like mission is designed and simulated around the so-called mission state predictor. Solved and unsolved exercises are included within the text - and not separated at the end of chapters - for better understanding, training and application. Simulated results and their graphical plots are developed through MATLAB/Simulink code.

Book Description :

The proceedings of the 2014 Reinventing Space conference present a number of questions in the context of a constantly innovating space industry, from addressing the future of global cooperation, investigating the impact of cuts in US government spending on the private space sector, and probing the overall future of the commercial launch sector. Space tourism and new technology promise the revival of interest in space development (the Apollo Era was the first period of intense space activity and growth). The need to create dramatically lower cost, responsive and reliable launch systems and spacecraft has never been more vital. Advances in technology are allowing smaller and cheaper satellites to be orbited - from cubesats to nanosatellites to femtosatellites. Thanks to more efficient new launch possibilities, low cost access to space is becoming ever more achievable. Commercial companies and countries are targeting the industry with new funding. Organised by the British Interplanetary Society, the presentations at this conference thoroughly address these challenges and opportunities.

Book Description :

1 1. 1 Introduction The (signal processing and storage) capacity ofthe human brain enables us to become powerful autonomous beings, but only if our brains operate in conjunction with (at least some of) our senses and muscles. Using these organs, we can interact with our environment, learn to adapt, and improve important aspects of our life. Similarly, the signal processing capabilities of modern electronics (computers) could be combined with electronic sensors and actuators to enable interaction with, and adaptation to, the (non-electrical) environment. This willlead to smarter and more powerful automated tools and machines. To facilitate and stimulate such a development, easy-to-use low-cost sensors are needed. The combination of electronic interface functions and a sensor in an integrated smart sensor, that provides a standard, digital, and bus-compatible output, would simplify the connection of sensors to standard electronic signal processors (microcontrollers, computers, etc. ). Currently, the calibration procedure, required for standardization of the sensor output signal level, contributes largely to the production costs of accurate sensors. To enable automation of the calibration procedure, and hence reduce the sensor fabrication costs, a digital calibrationjunction should be included in the smart sensor.
