Spatio-Temporal Modeling and Device Optimization of Passively Mode-Locked Semiconductor Lasers (Springer Theses)
by Stefan MeineckeThis thesis investigates passively mode-locked semiconductor lasers by numerical methods. The understanding and optimization of such devices is crucial to the advancement of technologies such as optical data communication and dual comb spectroscopy. The focus of the thesis is therefore on the development of efficient numerical models, which are able both to perform larger parameter studies and to provide quantitative predictions. Along with that, visualization and evaluation techniques for the rich spatio-temporal laser dynamics are developed; these facilitate the physical interpretation of the observed features.The investigations in this thesis revolve around two specific semiconductor devices, namely a monolithically integrated three-section tapered quantum-dot laser and a V-shaped external cavity laser. In both cases, the simulations closely tie in with experimental results, which have been obtained in collaboration with the TU Darmstadt and the ETH Zurich. Based on the successful numerical reproduction of the experimental findings, the emission dynamics of both lasers can be understood in terms of the cavity geometry and the active medium dynamics. The latter, in particular, highlights the value of the developed simulation tools, since the fast charge-carrier dynamics are generally not experimentally accessible during mode-locking operation. Lastly, the numerical models are used to perform laser design explorations and thus to derive recommendations for further optimizations.

Spatiotemporal Modeling of Cancer Immunotherapy: Partial Differential Equation Analysis in R
by William E. SchiesserThe focus of this book is a detailed discussion of a dual cancer vaccine (CV)-immune checkpoint inhibitor (ICI) mathematical model formulated as a system of partial differential equations (PDEs) defining the spatiotemporal distribution of cells and biochemicals during tumor growth.A computer implementation of the model is discussed in detail for the quantitative evaluation of CV-ICI therapy. The coding (programming) consists of a series of routines in R, a quality, open-source scientific computing system that is readily available from the internet. The routines are based on the method of lines (MOL), a general PDE algorithm that can be executed on modest computers within the basic R system. The reader can download and use the routines to confirm the model solutions reported in the book, then experiment with the model by varying the parameters and modifying/extending the equations, and even studying alternative models with the PDE methodology demonstrated by the CV-ICI model.Spatiotemporal Modeling of Cancer Immunotherapy: Partial Differential Equation Analysis in R facilitates the use of the model, and more generally, computer- based analysis of cancer immunotherapy mathematical models, as a step toward the development and quantitative evaluation of the immunotherapy approach to the treatment of cancer.
Spears of God
by Howard V. HendrixIn the early decades of the twenty-first century, the most commonly held truth is that knowledge is power. Yet a select few men and women begin to suspect what few will admit: we know nothing at all. The world’s oil resources have dwindled. The rich are turning richer and the power-mongers are becoming more powerful. China and the United States dominate the globe in a geopolitical chess match. The human mind has merged with the cybergrid, yet the human race seems not to have evolved much at all. ...
Special Computer Architectures for Pattern Processing
by King-Sun FuIt has been recognized for a long time that a conventional sequential processor is inefficient for operations on pictorial data where relatively simple operations need to be performed on a large number of data elements (pixels). Though many parallel processing architectures for picture processing have been proposed in the past, very few have actually been implemented due to the costs involved. With LSI technology, it is becoming possible to realize parallel architectures at a modest cost. In the following the authors review some of the proposed architectures for pattern recognition and image processing.

Special Effects: Still in Search of Wonder (Film and Culture Series)
by Michele PiersonDesigned to trick the eye and stimulate the imagination, special effects have changed the way we look at films and the worlds created in them. Computer-generated imagery (CGI), as seen in Hollywood blockbusters like Star Wars, Terminator 2, Jurassic Park, Independence Day, Men in Black, and The Matrix, is just the latest advance in the evolution of special effects. Even as special effects have been marveled at by millions, this is the first investigation of their broader cultural reception. Moving from an exploration of nineteenth-century popular science and magic to the Hollywood science fiction cinema of our time, Special Effects examines the history, advancements, and connoisseurship of special effects, asking what makes certain types of cinematic effects special, why this matters, and for whom. Michele Pierson shows how popular science magazines, genre filmzines, and computer lifestyle magazines have articulated an aesthetic criticism of this emerging art form and have helped shape how these hugely popular on-screen technological wonders have been viewed by moviegoers.

Special Operations from a Small State Perspective
by Gunilla Eriksson Ulrica PetterssonThis book offers different perspectives on the utilization and development of special operations forces (SOF) in small states. Across the chapters, the authors argue that small states can use and develop this very unique capability both at a tactical and operational level, but also as a strategic instrument in the modern complex security environment. The study finds that SOF in small states has a new role to play and that it needs to become a more agile and flexible force, ready to address future security challenges. A reorientation in favour of SOF from a small state perspective is crucial both due to the changing security situation in Europe, and the need to economise military resources.
