by Steve Souders

Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to:Make Fewer HTTP RequestsUse a Content Delivery NetworkAdd an Expires HeaderGzip ComponentsPut Stylesheets at the TopPut Scripts at the BottomAvoid CSS ExpressionsMake JavaScript and CSS ExternalReduce DNS LookupsMinify JavaScriptAvoid RedirectsRemove Duplicates ScriptsConfigure ETagsMake Ajax CacheableIf you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable."If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore."-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector"Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance."-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation

High Tech Trash: Digital Devices, Hidden Toxics, and Human Health

by Elizabeth Grossman

The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients.High Tech Trash is a wake-up call to the importance of the e-waste issue and the health hazards involved. Americans alone own more than two billion pieces of high tech electronics and discard five to seven million tons each year. As a result, electronic waste already makes up more than two-thirds of the heavy metals and 40 percent of the lead found in our landfills. But the problem goes far beyond American shores, most tragically to the cities in China and India where shiploads of discarded electronics arrive daily. There, they are "recycled"-picked apart by hand, exposing thousands of workers and community residents to toxics.As Grossman notes, "This is a story in which we all play a part, whether we know it or not. If you sit at a desk in an office, talk to friends on your cell phone, watch television, listen to music on headphones, are a child in Guangdong, or a native of the Arctic, you are part of this story."The answers lie in changing how we design, manufacture, and dispose of high tech electronics. Europe has led the way in regulating materials used in electronic devices and in e-waste recycling. But in the United States many have yet to recognize the persistent human health and environmental effects of the toxics in high tech devices. If Silent Spring brought national attention to the dangers of DDT and other pesticides, High Tech Trash could do the same for a new generation of technology's products.

High Tech and High Heels in the Global Economy: Women, Work, and Pink-Collar Identities in the Caribbean

by Carla Freeman

High Tech and High Heels in the Global Economy is an ethnography of globalization positioned at the intersection between political economy and cultural studies. Carla Freeman's fieldwork in Barbados grounds the processes of transnational capitalism--production, consumption, and the crafting of modern identities--in the lives of Afro-Caribbean women working in a new high-tech industry called "informatics. " It places gender at the center of transnational analysis, and local Caribbean culture and history at the center of global studies. Freeman examines the expansion of the global assembly line into the realm of computer-based work, and focuses specifically on the incorporation of young Barbadian women into these high-tech informatics jobs. As such, Caribbean women are seen as integral not simply to the workings of globalization but as helping to shape its very form. Through the enactment of "professionalism" in both appearances and labor practices, and by insisting that motherhood and work go hand in hand, they re-define the companies' profile of "ideal" workers and create their own "pink-collar" identities. Through new modes of dress and imagemaking, the informatics workers seek to distinguish themselves from factory workers, and to achieve these new modes of consumption, they engage in a wide array of extra income earning activities. Freeman argues that for the new Barbadian pink-collar workers, the globalization of production cannot be viewed apart from the globalization of consumption. In doing so, she shows the connections between formal and informal economies, and challenges long-standing oppositions between first world consumers and third world producers, as well as white-collar and blue-collar labor. Written in a style that allows the voices of the pink-collar workers to demonstrate the simultaneous burdens and pleasures of their work, High Tech and High Heels in the Global Economy will appeal to scholars and students in a wide range of disciplines, including anthropology, cultural studies, sociology, women's studies, political economy, and Caribbean studies, as well as labor and postcolonial studies.

High Throughput Imaging Technology (Advances in Optics and Optoelectronics)

by Yutong Li Zhengjun Liu

This book highlights a comprehensive introduction to high-throughput imaging, with the focus on the principles and methods. High-throughput imaging has become a research trend in the field of optics. It combines fast imaging, super-resolution imaging and large field of view imaging, improving the performance of the imaging system in many aspects. The development of a fast and high-throughput imaging system requires integration of optics, mathematics, programming, and other related science and technology. They bridge the theory and the system and realize the software-hardware integration, finally achieving high-performance imaging. An effective evaluation criterion of high-throughput imaging is the spatio-temporal bandwidth product, which provides guidance for research. The imaging technology with better comprehensive performance is the key target of research. Nowadays, new super-resolution imaging technologies and high-throughput imaging technologies have been emerging one after another, together with a number of new technical indicators. However, the integration and cascade of various technologies is still a very difficult challenge, and different technologies are difficult to be used in combination because of differences in physical space and technical means. Creating an imaging system with fast and high-throughput imaging capability is an urgent research task, which has important economic and social benefits for practical applications such as observing the dynamic (transient) process of large-size targets and on-line detection. High-throughput imaging is one of the major research goals of global research teams in optical imaging. This book summarizes latest research advances and introduces a variety of imaging methods targeting key problems, bringing together new theories and technologies in the aspects of high resolution, large field of view and fast imaging. The book provides a handy reference and systematic handbook for graduate students, researchers, and technicians engaged in the study, research and work in optical imaging.

High-Impact eportfolio Practice: A Catalyst for Student, Faculty and Institutional Learning

by Bret Eynon Laura M. Gambino

At a moment when over half of US colleges are employing ePortfolios, the time is ripe to develop their full potential to advance integrative learning and broad institutional change. The authors outline how to deploy the ePortfolio as a high-impact practice and describe widely-applicable models of effective ePortfolio pedagogy and implementation that demonstrably improve student learning across multiple settings. Drawing on the campus ePortfolio projects developed by a constellation of institutions that participated in the Connect to Learning network, Eynon and Gambino present a wealth of data and revealing case studies. Their broad-based evidence demonstrates that, implemented with a purposeful framework, ePortfolios correlate strongly with increased retention and graduation rates, broadened student engagement in deep learning processes, and advanced faculty and institutional learning. The core of the book presents a comprehensive research-based framework, along with practical examples and strategies for implementation, and identifies the key considerations that need to be addressed in the areas of Pedagogy, Professional Development, Outcomes Assessment, Technology and Scaling Up. The authors identify how the ePortfolio experience enhances other high-impact practices (HIPs) by creating unique opportunities for connection and synthesis across courses, semesters and co-curricular experiences. Using ePortfolio to integrate learning across multiple HIPs enables students reflect and construct a cohesive signature learning experience. This is an invaluable resource for classroom faculty and educational leaders interested in transformative education for 21st century learners.

High-Level Models of Unconventional Computations: A Case Of Plasmodium (Studies in Systems, Decision and Control #159)

by Krzysztof Pancerz Andrew Schumann

This book shows that the plasmodium of Physarum polycephalum can be considered a natural labelled transition system, and based on this, it proposes high-level programming models for controlling the plasmodium behaviour. The presented programming is a form of pure behaviourism: the authors consider the possibility of simulating all basic stimulus–reaction relations. As plasmodium is a good experimental medium for behaviouristic models, the book applies the programming tools for modelling plasmodia as unconventional computers in different behavioural sciences based on studying the stimulus–reaction relations. The authors examine these relations within the framework of a bio-inspired game theory on plasmodia they have developed i.e. within an experimental game theory, where, on the one hand, all basic definitions are verified in experiments with Physarum polycephalum and Badhamia utricularis and, on the other hand, all basic algorithms are implemented in the object-oriented language for simulations of plasmodia. The results allow the authors to propose that the plasmodium can be a model for concurrent games and context-based games.

High-Level Subject Access Tools and Techniques in Internet Cataloging

by Judith Ahronheim

Is your library's portal as efficient as it could be? High-Level Subject Access Tools and Techniques explores the potential and early development of high-level subject access. It examines Web tools and traditionally maintained library structures that facilitate the automated relation of resources to high-level subject categories based on the descriptive metadata that already exists in traditional library records. It includes a research study of high-level subject browse structures, as well as hands-on reports of actual projects and development activities and an examination of the environment in which demand for high-level subject access arises. From the editor: As the World Wide Web and graphic user interfaces developed in the 90s, libraries began to build gateways for their online resources. These gateways allowed library users to employ the browse, point, and click approach to resource discovery that they had come to expect from online tools. Most of these interfaces amounted to little more than hand-constructed lists of links. Today, many libraries offer access to users through a set list of broad topics, sometimes called a high-level browse display. Methods for populating these subject categories remain crude and their maintenance requires considerable resources. As a result, libraries have begun to look at ways of applying traditional techniques associated with cataloging to these new interfaces. Several goals are involved in these developments. Many hope to reuse data from library catalogs and thus limit maintenance burdens. Others seek to apply a more standard set of tools and principles to the construction of portals to allow greater cooperation among institutions that want to interoperate with each other. This pathbreaking book examines vital issues in high-level subject access, including: subject trees and their relationship to the structure inherent in Dewey Classification emerging patterns in the development of browsing services, including a hierarchy of subjects that is not based in classification, a map that relates data from catalog records to the subject hierarchy, and tools for extracting data from a catalog and storing it in a separate database to produce a more flexible display task-based (as opposed to materials-based) subject lists the social issues that are associated with choosing categoriesbased on the nature and activity of an institution's library users the political issues involved in selecting disciplines or topics for a browsing service And presents fascinating case studies of: Columbia University's efforts to build an automatically generated browsable display based on Library of Congress Classification as it occurs in catalog records the High-Level Thesaurus Project (HILT), in which a group of libraries, archives, and museums attempted to find a common method for high-level subject access via portal

High-Level Verification

by Sorin Lerner Sudipta Kundu Rajesh K. Gupta

Given the growing size and heterogeneity of Systems on Chip (SOC), the design process from initial specification to chip fabrication has become increasingly complex. This growing complexity provides incentive for designers to use high-level languages such as C, SystemC, and SystemVerilog for system-level design. While a major goal of these high-level languages is to enable verification at a higher level of abstraction, allowing early exploration of system-level designs, the focus so far for validation purposes has been on traditional testing techniques such as random testing and scenario-based testing. This book focuses on high-level verification, presenting a design methodology that relies upon advances in synthesis techniques as well as on incremental refinement of the design process. These refinements can be done manually or through elaboration tools. This book discusses verification of specific properties in designs written using high-level languages, as well as checking that the refined implementations are equivalent to their high-level specifications. The novelty of each of these techniques is that they use a combination of formal techniques to do scalable verification of system designs completely automatically. The verification techniques presented in this book include methods for verifying properties of high-level designs and methods for verifying that the translation from high-level design to a low-level Register Transfer Language (RTL) design preserves semantics. Used together, these techniques guarantee that properties verified in the high-level design are preserved through the translation to low-level RTL.

High-Order Finite Difference and Finite Element Methods for Solving Some Partial Differential Equations (Synthesis Lectures on Engineering, Science, and Technology)

by Ulziibayar Vandandoo Tugal Zhanlav Ochbadrakh Chuluunbaatar Alexander Gusev Sergue Vinitsky Galmandakh Chuluunbaatar

The monograph is devoted to the construction of the high-order finite difference and finite element methods for numerical solving multidimensional boundary-value problems (BVPs) for different partial differential equations, in particular, linear Helmholtz and wave equations, nonlinear Burgers’ equations, and elliptic (Schrödinger) equation. Despite of a long history especially in development of the theoretical background of these methods there are open questions in their constructive implementation in numerical solving the multidimensional BVPs having additional requirement on physical parameters or desirable properties of its approximate solutions. Over the last two decades many papers on this topics have been published, in which new constructive approaches to numerically solving the multidimensional BVPs were proposed, and its highly desirable to systematically collect these results. This motivate us to write thus monograph based on our research results obtained in collaboration with the co-authors. Since the topic is importance we believe that this book will be useful to readers, graduate students and researchers interested in the field of computational physics, applied mathematics, numerical analysis and applied sciences
