Computer languages and computer graphics have become the primary modes of human-computer interaction. This book provides a basic introduction to "Real and Virtual Environment" computer modelling. Graphics models are used to illustrate both the way computer languages are processed and also used to create computer models of graphic displays. Computer languages have been bootstrapped from machine code, to high-level languages such as Java, to animation scripting languages. Integrating graphic and computer models takes this support for programming, design and simulation work, one step further, allowing interactive computer graphic displays to be used to construct computer models of both real and virtual environment systems. The Java language is used to implement basic algorithms for language translation, and to generate graphic displays. It is also used to simulate the behaviour of a computer system, to explore the way programming and design-simulation environments can be put together.

The book is a developed history of the radiological sciences - covering the back-story to Roentgen's discovery, the discovery itself and immediate reception the early days of radiology leading to classical radiology (the pre-digital world). The 1970s as the 'golden decade' of radiology will be covered in detail, with the development of CT, MRI and modern interventional radiology. It will appeal to interested members of the public, to those working in the field, and to historians of medicine and science.

A Case for Mixed-Audience with Reference to the Warning Passages in the Book of Hebrews discusses the nature of the warnings in Hebrews and how these warnings relate to the theological question of the eternal security of believers. The main argument is that these warnings are intended to target a particular segment of the author's community, about whose appropriation of and subsequent attitude toward the Christian message he was deeply concerned. That is to say, while the book of Hebrews is addressed as a message of encouragement to the community as a whole, its warnings are aimed at a certain element in the community whose salvation is threatened by a possible dangerous course of action. The book implies that while the author is persuaded that the majority in the community are genuine believers, there are some about whose salvation he doubts; hence the «case for a mixed-audience. What is threatened, therefore, is not a salvation already possessed, but the salvation of those in danger of coming up short. Theologically, the work falls within the sphere of the Calvinistic-Arminian debate regarding the assurance of salvation and the perseverance of the saints. It argues strongly for the Calvinistic position, but does so within the confines of the discipline of biblical studies, and lends extensive exegetical support to the Calvinistic position on the warning passages. The book is highly recommended for Bible College and seminary students and professors, as well as pastors and lay leaders who must give answers to their parishoners on those tough warning passages in Hebrews.

The Polish composer Henryk Górecki (born 1933) achieved world-wide renown in 1992 when his Third Symphony, written in 1976, was recorded on CD and became an international bestseller. It is now one of the best known musical compositions of recent years, yet Górecki's other music is still relatively little known. This study, the first detailed account of his works in any language, provides biographical information as background to the music, and is by a leading enthusiast for Górecki's music.

Evolutionary biomechanics is the study of evolution through the analysis of biomechanical systems. Its unique advantage is the precision with which physical constraints and performance can be predicted from first principles. Instead of reviewing the entire breadth of the biomechanical literature, a few key examples are explored in depth as vehicles for discussing fundamental concepts, analytical techniques, and evolutionary theory. Each chapter develops a conceptual theme, developing the underlying theory and techniques required for analyses in evolutionary biomechanics. Examples from terrestrial biomechanics, metabolic scaling, and bird flight are used to analyse how physics constrains the design space that natural selection is free to explore, and how adaptive evolution finds solutions to the trade-offs between multiple complex conflicting performance objectives. Evolutionary Biomechanics is suitable for graduate level students and professional researchers in the fields of biomechanics, physiology, evolutionary biology and palaeontology. It will also be of relevance and use to researchers in the physical sciences and engineering.

Witold Lutoslawski was one of the most important composers of the twentieth century, whose significance extends far beyond his native Poland. His vita is just as captivating as his compositionally path-breaking music. Witold Lutoslawski (1913-1994) was one of the most important composers of the twentieth century. His significance extends far beyond his native Poland: his classical music was premiered by internationally renowned performers likethe LaSalle Quartet and Krystian Zimerman, and his symphonies, concertante, chamber, instrumental and vocal music are produced by the leading labels of the recording industry. Lutoslawski's vita is just as captivating as his compositionally path-breaking music. He lived through the Second World War and brutal German oppression of Poland, negotiated the challenges of Soviet influence and fluctuating local politics during Poland's post-war transition to communism, and finally strove for a new voice in the post-Stalin Thaw of the mid-1950s. Lutoslawski's Worlds is a landmark volume which looks at the multi-faceted spheres that informed the composer's life and works andrepresents a new departure in the study of his music. Throughout his life, he steered musicologists away from the connections between his extraordinary biography and concert music. He also sought to minimize scholarly attention to the many other spheres of creative activity - popular music, theatre music, film scoring, propaganda music, and educational music - that occupied him. In this volume, for the first time, the world's leading Lutoslawski scholars consider the full range of his musical output and the biographical, cultural and historical contexts in which those musics were created. It contends that all of Lutoslawski's worlds are equally worthy of study, because each represents an opportunity better to understand the life and music of a figure of paramount importance to the critical and cultural history of twentieth-century music.

This book looks at Polish music since 1937 and its interaction with political and cultural turmoil. In Part I musical developments are placed in the context of the socio-political upheavals of inter-war Poland, Nazi occupation, and the rise and fall of the Stalinist policy of socialist realism (1948-54). Part II investigates the nature of the 'thaw' between 1954 and 1959, focusing on the role of the 'Warsaw Autumn' Festival. Part III discusses how composers reacted to the onset of serialism by establishing increasingly individual voices in the 1960s. In addition to a discussion of 'sonorism' (from Penderecki to Szalonek), it considers how different generations responded to the modernist aesthetic (Bacewicz and Lutoslawski, Baird and Serocki, Gorecki and Krauze). Part IV views Polish music since the 1970s, including the issue of national identity and the arrival of a talented generation and its ironic, postmodern slant on the past.
