Calibrating the Cosmos : How Cosmology Explains Our Big Bang Universe
Calibrating the Cosmos describes hard science, but is gently written. It explains in clear, non-mathematical language the measurements and the interpretation of the resulting data that have led to the current understanding of the origin, evolution and properties of our expanding Big Bang universe. Many people have a sketchy idea of the work of cosmologists, but Professor Levin’s experience in teaching both scientific and liberal arts students has enabled him to impart much of our current thinking without resorting to difficult mathematics. Theoretical concepts are emphasized, in particular the symmetries of homogeneity and isotropy enjoyed by our universe on the largest scales, how these symmetries lead to only one quantity being needed to describe the growth of the universe from its infancy to the present time, and how the so-called parameters of the universe are the ingredients used to construct the model universes to which ours – the real thing – is compared.
Calculus of one variable
Aimed at first-year undergraduates in mathematics and the physical sciences, the only prerequisites are basic algebra, coordinate geometry and the beginnings of differentiation as covered in school. The transition from school to university mathematics is addressed by means of a systematic development of important classes of techniques, and through careful discussion of the basic definitions and some of the theorems of calculus, with proofs where appropriate, but stopping short of the rigour involved in Real Analysis.The influence of technology on the learning and teaching of mathematics is recognised through the use of the computer algebra and graphical package MAPLE to illustrate many of the ideas.
Calculus and mechanics on two-point homogenous riemannian spaces
The present monograph gives a short and concise introduction to classical and quantum mechanics on two-point homogenous Riemannian spaces, with empahsis on spaces with constant curvature. Chapter 1-4 provide the basic notations from differential geometry for studying two-body dynamics in these spaces. Chapter 5 deals with the problem of finding explicitly invariant expressions for the two-body quantum Hamiltonian. Chapter 6 addresses one-body problems in a central potential. Chapter 7 studies the classical counterpart of the quantum system of chapter 5. Chapter 8 investigates some applications in the quantum realm, namely for the coulomb and oscillator potentials.

Business processes : An archival science approach to collaborative decision making, records, and knowledge management
Collaborative decision making processes are a form of communication inside organizations. Their functioning can teach lessons for the design of electronic office systems. Those processes are open ended and therefore decide themselves on their form. Like oral deliberations which cannot be modelled in advance any open ended communication process needs means for common control over the further advancement and the ending of the process.The book is a reworked English version of a thesis for the official qualification for university professorship accepted by the German University of Administrative Sciences Speyer.

Business Ethics of Innovation
Firms that operate in a market economy often depend upon innovations in order to achieve competitive advantages that sustainably secure their survival. Business ethics is thus largely concerned with questions about the decisional freedoms involved in innovation processes. Innovations oftentimes raise novel questions about the role of the state or the structure of society. Business ethics needs to provide a framework for balancing the different perspectives, values, and interests at stake. This balance must be achieved at the level of the firm in order to facilitate adequate long term decisions, but it should also be sought at higher, including regulatory, levels. Achieving this balance will require an ethical framework for entrepreneurial action.
Buried Waste in the Seabed – Acoustic Imaging and Bio-Toxicity : Results from the European SITAR Project
Buried waste on the seabed is a major source of pollution. But, very often, waste sites are not known until a serious problem occurs, or are not adequately mapped. Recent examples around Europe include WWI and WWII ammunition dump sites (e.g. Beufort Dyke in the UK), dumped nuclear submarines in the Arctic Seas, clandestine or hidden toxic-waste in the Baltic Sea and the North Sea.. Even if properly documented, waste sites evolve with time (dumped material can move with currents and tides, especially on a scale of decades; toxic-material barrels can corrode and leak). This book shows the results of a concerted EU-funded effort to tackle this problem and find innovative ways to identify and map toxic waste sites ona the seabed, whether they have been covered with sediments or not. These results are applicable to any region on the seabed in the entire world.
Buildings : Theory and Applications
This book treats Jacques Tits's beautiful theory of buildings, making that theory accessible to readers with minimal background. It includes all the material of the earlier book Buildings by the second-named author, published by Springer-Verlag in 1989, which gave an introduction to buildings from the classical (simplicial) point of view. This new book also includes two other approaches to buildings, which nicely complement the simplicial approach: On the one hand, buildings may be viewed as abstract sets of chambers with a Weyl-group-valued distance function; this point of view has become increasingly important in the theory and applications of buildings. On the other hand, buildings may be viewed as metric spaces. Beginners can still use parts of the new book as a friendly introduction to buildings, but the book also contains valuable material for the active researcher.
Building the Inclusive City : Governance, Access, and the Urban Transformation of Dubai
This book is an anthropological urban study of the Emirate of Dubai, its institutions, and their evolution. It provides a contemporary history of disability in city planning from a non-Western perspective and explores the cultural context for its positioning. Three insights inform the author’s approach. First, disability research, much like other urban or social issues, must be situated in a particular place
Building a Resilient and Sustainable Agriculture in Sub-Saharan Africa
What are the challenges and action points for agricultural sustainability in Sub-Saharan Africa? This collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. Each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on Africa’s sustainable transformation process, which is in line with the international development agenda. Although agriculture remains the main source of income for Africa’s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. This volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for Africa’s food security and structural transformation.
Buchi neri nel mio bagno di schiuma : L’enigma di Einstein = Black holes in my bubble bath : Einstein's riddle
Einstein's Enigma, or black holes in my foam bath, tells the story of the theory of gravitation, from its beginnings to the latest developments in astrophysics, focusing on Albert Einstein's theory of general relativity and the physics of black holes. Through engaging conversations and diagrams scribbled on paper napkins, the rudiments of relativity, space-time and many aspects of modern physics follow one another. In skits narrated with pedagogical skill and remarkable literary talent, the reader will come across the informal lessons that a cosmopolitan astrophysicist gives to his friend Alfie, a free lance organizer of research projects. Join in the intellectual fun and get excited with sparkling ideas, while with your imagination you enjoy a relaxing soak in this magical tub!
Browning Agents and Active Particles : Collective Dynamics in the Natural and Social Sciences
Lays out a vision for a coherent framework for understanding complex systems'' (from the foreword by J. Doyne Farmer). By developing the genuine idea of Brownian agents, the author combines concepts from informatics, such as multiagent systems, with approaches of statistical many-particle physics. This way, an efficient method for computer simulations of complex systems is developed which is also accessible to analytical investigations and quantitative predictions. The book demonstrates that Brownian agent models can be successfully applied in many different contexts, ranging from physicochemical pattern formation, to active motion and swarming in biological systems, to self-assembling of networks, evolutionary optimization, urban growth, economic agglomeration and even social systems.
Brouwer meets Husserl : On the Phenomenology of Choice Sequences
Can the straight line be analysed mathematically such that it does not fall apart into a set of discrete points, as is usually done but through which its fundamental continuity is lost? And are there objects of pure mathematics that can change through time? The mathematician and philosopher L.E.J. Brouwer argued that the two questions are closely related and that the answer to both is "yes''. To this end he introduced a new kind of object into mathematics, the choice sequence. But other mathematicians and philosophers have been voicing objections to choice sequences from the start. This book aims to provide a sound philosophical basis for Brouwer's choice sequences by subjecting them to a phenomenological critique in the style of the later Husserl.
Broadband Opto-Electrical Receivers in Standard CMOS
Broadband Opto-Electrical Receivers in Standard CMOS starts from the basic fundamentals, necessary for the design of opto-electronic interface circuits. The book continues with an in-depth analysis of the photodiode, transimpedance amplifier (TIA) and limiting amplifier (LA). To thoroughly understand the light detection mechanisms in silicon, first a one-dimensional and second a two-dimensional model is developed. Analytical design equations are derived to guide the design of the amplifying circuits. For the TIA, the focus lies on the sensitivity-speed trade-off. For the LA, a high gain-bandwidth is pursued. Several practical design examples reveal the subtleties and challenges encountered during the design of high-performance analog circuits.
Broadband Fixed Wireless Access : A System Perspective
Broadband Fixed Wireless Access provides a systematic overview of the emerging WiMax technology, and much of the material is based on the practical experiences of the authors in building broadband wireless systems. This material will be of significant interest to network architects and developers of broadband fixed wireless access products. With the adoption of the IEEE 802.16 standard and the advent of next generation equipment, the WiMax technology has been growing in interest. The authors discuss applications at microwave frequencies between 2 and 11 GHz that could be attractive options for operators without an existing access infrastructure for reaching end users with broadband services. This introductory volume demystifies the technology and provides technical exposure to the various system trade-offs. Additionally.

Research with high brilliant photon beams are used, for example for practical applications in pharmacy, electronics and nanotechnology. Such practical relevance promoted the design and construction of now more than 50 such facilities worldwide. Overview and specialized talks on the status and highlights of newly constructed light sources (ALBA, SPEAR3, European XFEL Facility, Siberian Synchrotron Radiation Center, CANDLE), on instrumentation and development of experimental techniques, and frontier research in life and material sciences using synchrotron radiation have been presented.
Bridging divides : Maritime canals as invasion corridors
Maritime canals dissolve natural barriers to the dispersal of marine organisms, thus providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. The introduction of alien species has proved to be one of the most profound and damaging of anthropogenic deeds - with both ecological and economic costs. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.
