The book describes the science gateway building technology developed in the SCI-BUS European project and its adoption and customization method, by which user communities, such as biologists, chemists, and astrophysicists, can build customized, domain-specific science gateways. Many aspects of the core technology are explained in detail, including its workflow capability, job submission mechanism to various grids and clouds, and its data transfer mechanisms among several distributed infrastructures. The book will be useful for scientific researchers and IT professionals engaged in the development of science gateways.
At the end of the year 2008, we have seen a strategic step towards a funct- ning HPC infrastructure on Tier-0 level in Germany. Based on an agreement ( Verwaltungsabkommen") between the Federal Ministry of Education and " Research (BMBF) and the state ministries for research of Baden-Wurttem- .. berg, Bayern, and Nordrhein-Westfalen, a budget of overall 400 Million Euro had been allocated - equally shared between federal and state authorities in a ?ve year time frame - to establish the next generation of HPC systems at the Gauss Centre for Supercomputing (GCS) - consisting of the three nat- nal supercomputing centres HLRS (Stuttgart), NIC/JSC (Julich), and LRZ .. (Munich). As part of that strategic initiative, in May 2009 already NIC/JSC has installed the ?rst phase of the GCS HPC Tier-0 resources, an IBM Blue Gene/P with roughly 300. 000 Cores, this time in Julic .. h, With that, the GCS provides the most powerfulhigh-performance computing infrastructure in - rope already today. HLRS and its partners in the GCS have agreed on a common strategy for the installation of the next generation of leading edge HPC systems. Over the next few years, HLRS and LRZ as the other two GCS centers will upgrade their systems accordingly. The plan is to have a Tier-0 HPC system within GCS operating at any time in this ?ve year period. Asanintermediatestep,HLRShasreplacedmostoftheirNECSX-8nodes by the NEC SX-9/12M192, a system with roughly 20 TFLOPs peak.
This unique, practical guide for postdoctoral researchers and graduate students explains how to build and perfect the necessary research tools and working skills to build a career in academia and beyond. It is based on successful training workshops run by the authors: first, it describes the tools needed for independent research, from writing papers to applying for academic jobs; it then introduces skills to thrive in a new job, including managing and interacting with others, designing a taught course and giving a good lecture; and it concludes with a section on managing your career, from how to manage stress to understanding the higher education system. Packed with helpful features encouraging readers to apply the theory to their individual situation, the book is also illustrated throughout with real-world case studies to enable readers to learn from others' experience. It is a vital handbook for everyone seeking to make a successful scientific career.
Why is it that, while women in the United States have generally made great strides in establishing parity with their male counterparts in educational attainment, they remain substantially underrepresented in the fields of science, technology, engineering, and mathematics (STEM)? Why is it that, in proportion to the PhDs they obtain in STEM, they attain fewer administrative and managerial positions in academia and industry than their numbers warrant and, moreover, are more likely leave the field once started in their careers? In the culture and context of women s advancement and satisfaction with careers in STEM, the data show that many challenges and obstacles remain.By showcasing the stories of eight women scientists who have achieved successful careers in the academy, industry and government, "Women Breaking In" offers vivid insights into the challenges and barriers that women face in entering STEM while also describing these women s motivations, the choices they made along their paths, and the intellectual satisfactions and excitement of scientific discovery they derive from their work."Women Breaking In" underscores issues aspiring women scientists will encounter on their journeys and what they can do to forestall potential obstacles, advocate for change, and fulfill their ambitions. And it speaks to the question: What can be done to encourage more women to specialize in science, mathematics, and engineering? In doctoral granting institutions, where women must start if they hope to earn advanced degrees, "Women Breaking In" can serve both as a student text and as guide for department chairs and deans who are concerned about organizational climate and culture and their impact on retention in STEM fields. At a broader level, this book offers advice and inspiration to women contemplating entering STEM fields, as well to the teachers, researchers, and administrators responsible for nurturing these women, growing enrollments in their disciplines, and developing creative and intellectual capital that the nation needs to compete in the global marketplace."
When a new extraordinary and outstanding theory is stated, it has to face criticism and skeptism, because it is beyond the usual concept. The fractional calculus though not new, was not discussed or developed for a long time, particularly for lack of its application to real life problems. It is extraordinary because it does not deal with 'ordinary' differential calculus. It is outstanding because it can now be applied to situations where existing theories fail to give satisfactory results. In this book not only mathematical abstractions are discussed in a lucid manner, with physical mathematical and geometrical explanations, but also several practical applications are given particularly for system identification, description and then efficient controls. The normal physical laws like, transport theory, electrodynamics, equation of motions, elasticity, viscosity, and several others of are based on 'ordinary' calculus. In this book these physical laws are generalized in fractional calculus contexts; taking, heterogeneity effect in transport background, the space having traps or islands, irregular distribution of charges, non-ideal spring with mass connected to a pointless-mass ball, material behaving with viscous as well as elastic properties, system relaxation with and without memory, physics of random delay in computer network; and several others; mapping the reality of nature closely. The concept of fractional and complex order differentiation and integration are elaborated mathematically, physically and geometrically with examples. The practical utility of local fractional differentiation for enhancing the character of singularity at phase transition or characterizing the irregularity measure of response function is deliberated. Practical results of viscoelastic experiments, fractional order controls experiments, design of fractional controller and practical circuit synthesis for fractional order elements are elaborated in this book. The book also maps theory of classical integer order differential equations to fractional calculus contexts, and deals in details with conflicting and demanding initialization issues, required in classical techniques. The book presents a modern approach to solve the 'solvable' system of fractional and other differential equations, linear, non-linear; without perturbation or transformations, but by applying physical principle of action-and-opposite-reaction, giving 'approximately exact' series solutions. Historically, Sir Isaac Newton and Gottfried Wihelm Leibniz independently discovered calculus in the middle of the 17th century. In recognition to this remarkable discovery, J.von Neumann remarked, "...the calculus was the first achievement of modern mathematics and it is difficult to overestimate its importance. I think it defines more equivocally than anything else the inception of modern mathematical analysis which is logical development, still constitute the greatest technical advance in exact thinking." This XXI century has thus started to 'think-exactly' for advancement in science & technology by growing application of fractional calculus, and this century has started speaking the language which nature understands the best.
In the 25 years since the 'Bodmer Report' kick-started the public understanding of science movement, there has been something of a revolution in science communication. However, despite the ever-growing demands of the public, policy-makers and the media, many scientists still find it difficult to successfully explain and publicise their activities or to understand and respond to people's hopes and concerns about their work. Bringing together experienced and successful science communicators from across the academic, commercial and media worlds, this practical guide fills this gap to provide a one-stop resource covering science communication in its many different forms. The chapters provide vital background knowledge and inspiring ideas for how to deal with different situations and interest groups. Entertaining personal accounts of projects ranging from podcasts, to science festivals, to student-run societies give working examples of how scientists can engage with their audiences and demonstrate the key ingredients in successful science communication.
In this innovative and groundbreaking work, the structure and evolution of scientific theories is examined in meticulous detail and rigorously analysed as never before. For the first time, scientific revolutions are presented as a natural consequence of the evolution of scientific theories and described with mathematical precision. Many new techniques are introduced and with the more precise understanding of the nature of the scientific enterprise obtained thereby, old philosophical problems are cast into a new light and shown to be susceptible to the same rigorous approach by which they may be completely solved. Numerous real examples from the sciences are given and discussed in detail, culminating in some startling results concerning the future development of science and that Holy Grail of physics, the possibility of a final, all-embracing Theory of Everything. Written in an eloquent and engaging style interspersed with occasional flashes of delicious humour, this book is destined to become a classic in the Philosophy of Science. It will doubtless be appreciated equally by philosophers and scientists alike as well as a wider, less specialised audience. Truly an important document and a major contribution to the literature; this is a work for the twenty-first century.
Indigenous peoples have passed down vital knowledge for generations from which local plants help cure common ailments, to which parts of the land are unsuitable for buildings because of earthquakes. Here, Hendry examines science through these indigenous roots, problematizing the idea that Western science is the only type that deserves that name.

As we enter the 21st century, there is an urgent need for new approaches to mathematics education emphasizing its relevance in young learners' futures. Modeling Students' Mathematical Modeling Competencies explores the vital trend toward using real-world problems as a basis for teaching mathematics skills, competencies, and applications. Blending theoretical constructs and practical considerations, the book presents papers from the latest conference of the ICTMA, beginning with the basics (Why are models necessary? Where can we find them?) and moving through intricate concepts of how students perceive math, how instructors teach-and how both can become better learners. Dispatches as varied as classroom case studies, analyses of math in engineering work, and an in-depth review of modeling-based curricula in the Netherlands illustrate modeling activities on the job, methods of overcoming math resistance, and the movement toward replicable models and lifelong engagement. A sampling of topics covered: How students recognize the usefulness of mathematics Creating the modeling-oriented classroom Assessing and evaluating students' modeling capabilities The relationship between modeling and problem-solving Instructor methods for developing their own models of modeling New technologies for modeling in the classroom Modeling Students' Mathematical Modeling Competencies offers welcome clarity and focus to the international research and professional community in mathematics, science, and engineering education, as well as those involved in the sciences of teaching and learning these subjects.
This collection of surveys consists in part of extensions of papers presented at the conferences on convexity at the Technische Universitat Wien (July 1981) and at the Universitat Siegen (July 1982) and in part of articles written at the invitation of the editors. This volume together with the earlier volume "Contributions to Geometry" edited by Tolke and Wills and published by Birkhauser in 1979 should give a fairly good account of many of the more important facets of convexity and its applications. Besides being an up to date reference work this volume can be used as an advanced treatise on convexity and related fields. We sincerely hope that it will inspire future research. Fenchel, in his paper, gives an historical account of convexity showing many important but not so well known facets. The articles of Papini and Phelps relate convexity to problems of functional analysis on nearest points, nonexpansive maps and the extremal structure of convex sets. A bridge to mathematical physics in the sense of Polya and Szego is provided by the survey of Bandle on isoperimetric inequalities, and Bachem's paper illustrates the importance of convexity for optimization. The contribution of Coxeter deals with a classical topic in geometry, the lines on the cubic surface whereas Leichtweiss shows the close connections between convexity and differential geometry. The exhaustive survey of Chalk on point lattices is related to algebraic number theory. A topic important for applications in biology, geology etc.

The concluding selection relates the urgent need to measure, evaluate and protect the quality of drinking water and describes a new state standard of drinking water quality."
"Provides the reader with a lucid and accessible entre to the
contentious issues surrounding the role of religion in American
public life." "A readable book that will be a valuable addition to university
libraries and useful reading in courses on science and
values." "Insightful and penetrating." "Goldberg's expertise in the legal system, science, and
contemporary social issues allows him to frame public debates in
their proper perspectives. His presentations of the relations
between law and religion offer insights that tend to be ignored and
he convincingly shows that religious values have a central place in
today's controversies." "This interesting book makes a strong demand on religiously
inclined readers . . . warning not to justify things of the spirit
by signs material. . . . Goldberg's warning is one to take
seriously." "An original, forthright argument that American religion has
sold its soul to science. . . . A well-reasoned counterweight to
recent science-worshipping titles." American religion, Steven Goldberg claims, has fallen into a trap. Just at the moment when it has amassed the political strength and won the legal right to participate effectively in public debate, it has lost its distinctive voice. Instead of speaking of human values, goals, and limits, it speaks in the language of science. In the United States, science has extraordinary influence and respect. American religious leaders seeking prestige for their point of view regularly couch their responsesto technological developments, or defend their faith, in scientific terms. They claim, for instance, that medical studies demonstrate the power of prayer, that science validates the Bible, including its account of creation, and that patenting the genetic code is dangerous because genes are the essence of who we are. But when ministers, priests, and rabbis expound on double-blind studies and the genetic causes of behavior, they do not elevate religion, Goldberg maintains, they trivialize it. Seduced by Science examines how, by allowing scientific discourse to set the terms of the debate, American religious leaders facilitate religion's move away from its more appropriate and important concerns of values, morality, and humility. Science can tell us a lot about what "is "but precious little about what "ought to be" and our religious leaders often miss the chance to add an important voice from a faith-based perspective to the public debate that follows scientific advances. Discussing the most recent and pressing collisions between science and religion-such as the medicinal benefits of prayer, the human genome project, and cloning-Goldberg raises the timely question of what the appropriate role of religion might be in public life today. Tackling the legal aspects of religious debate, Goldberg suggests ways that religious leaders might confront new scientific developments in a more meaningful fashion.
THE MATHEMATICAL BIOLOGY OF DIATOMS This book contains unique, advanced applications using mathematics, algorithmic techniques, geometric analysis, and other computational methods in diatom research. Historically, diatom research has centered on taxonomy and systematics. While these topics are of the utmost importance, other aspects of this important group of unicells have been increasingly explored in the biological sciences. While mathematical applications are still rare, they are starting take hold and provide an extensive avenue of new diatom research, including applications in multidisciplinary fields. The work contained in this volume is an eclectic mix of analytical studies on diatoms. Mathematical treatment of the various biological disciplines covered in this book range from implicit, but succinct studies to more elaborate detailed computational studies. Topics include growth models, nanostructure, nanoengineering, cell growth, araphid diatoms, valve ontogeny, diatom metabolism, diatom motility, synchronization, diatom kinematics, photonics, biogenic sensors, photochemistry, diatom light response, colony growth, siliceous unicells, algal kinetics, diatom structure, diatom imaging, functional morphology, geometric structure, biomineralization, high-resolution imaging, non-destructive imaging, and 3D structure. This wide-ranging volume provides an introductory as well as an advanced treatment of recent interests in diatom research. The mathematical research in this volume may be applicable to studies of other unicells, biomechanics, biological processes, physio-chemical analyses, or nanoscience.
The editors of this volume argue that future research into complex animal societies and intelligence will change the perception of animals as gene machines, programmed to act in particular ways and perhaps elevate them to a status much closer to our own. At a time when humans are perceived more biologically than ever before, and animals as more cultural, are we about to witness the dawn of a truly unified social science, one with a distinctly cross-specific perspective?
