New material includes multiple linear regression using MREG, principal-components analysis, Monte Carlo integration, parameterization of the force field, and molecular modeling software. Major areas covered include: * Error, Statistics, and the Floating-Point Number System * Curve Fitting * Multiple Linear Regression Analysis * Numerical Integration * Numerical Solution of Differential Equations * Matrix Methods and Linear Equation Systems * Random Numbers and Monte Carlo Simulation * Simplex Optimization * Chemical Structure Information Handling * Mathematical Graph Theory * Substructure Searching * Molecular Mechanics and Molecular Dynamics * Pattern Recognition * Artificial Intelligence and Expert Systems * Spectroscopic Library Searching and Structure Elucidation * Graphical Display of Data and of Molecules Whatever your area of research, this comprehensive, lucidly written book offers an indispensable resource of computer applications that will facilitate your work.
The latest edition of this classic, definitive reference work for all those involved in environmental health, is opened by a new chapter which discusses the changing approaches to Environmental Health. There are other new chapters on risk assessment and the epidemiology of non-infectious diseases with new introductory chapters both for food safety and occupational health and safety which place those activities into the rapidly changing conceptual and organisational contexts. There is additional work on meat hygiene to highlight developments in that area and substantial material on the enforcement function and on air pollution. There are also new organisational case studies.
From the first digital computer to the dot-com crash—a story of individuals, institutions, and the forces that led to a series of dramatic transformations. This engaging history covers modern computing from the development of the first electronic digital computer through the dot-com crash. The author concentrates on five key moments of transition: the transformation of the computer in the late 1940s from a specialized scientific instrument to a commercial product; the emergence of small systems in the late 1960s; the beginning of personal computing in the 1970s; the spread of networking after 1985; and, in a chapter written for this edition, the period 1995-2001. The new material focuses on the Microsoft antitrust suit, the rise and fall of the dot-coms, and the advent of open source software, particularly Linux. Within the chronological narrative, the book traces several overlapping threads: the evolution of the computer's internal design; the effect of economic trends and the Cold War; the long-term role of IBM as a player and as a target for upstart entrepreneurs; the growth of software from a hidden element to a major character in the story of computing; and the recurring issue of the place of information and computing in a democratic society. The focus is on the United States (though Europe and Japan enter the story at crucial points), on computing per se rather than on applications such as artificial intelligence, and on systems that were sold commercially and installed in quantities.

his textbook is designed to teach a first course in Information Technology (IT) to all undergraduate students. In view of the all-pervasive nature of IT in today’s world a decision has been taken by many universities to introduce IT as a compulsory core course to all Bachelor’s degree students regardless of their specialisation. This book is intended for such a course. The approach taken in this book is to emphasize the fundamental “Science” of Information Technology rather than a cook book of skills. Skills can be learnt easily by practice with a computer and by using instructions given in simple web lessons that have been cited in the References. The book defines Information Technology as the technology that is used to acquire, store, organize, process and disseminate processed data, namely, information. The unique aspect of the book is to examine processing all types of data: numbers, text, images, audio and video data. As IT is a rapidly changing field, we have taken the approach to emphasize reasonably stable, fundamental concepts on which the technology is built. A unique feature of the book is the discussion of topics such as image, audio and video compression technologies from first principles. We have also described the latest technologies such as ‘e-wallets’ and ‘cloud computing’. The book is suitable for all Bachelor’s degree students in Science, Arts, Computer Applications, and Commerce. It is also useful for general reading to learn about IT and its latest trends. Those who are curious to know, the principles used to design jpg, mp3 and mpeg4 compression, the image formats—bmp, tiff, gif, png, and jpg, search engines, payment systems such as BHIM and Paytm, and cloud computing, to mention a few of the technologies discussed, will find this book useful. KEY FEATURES • Provides comprehensive coverage of all basic concepts of IT from first principles • Explains acquisition, compression, storage, organization, processing and dis-semination of multimedia data • Simple explanation of mp3, jpg, and mpeg4 compression • Explains how computer networks and the Internet work and their applications • Covers business data processing, World Wide Web, e-commerce, and IT laws • Discusses social impacts of IT and career opportunities in IT and IT enabled services • Designed for self-study with every chapter starting with learning objectives and concluding with a comprehensive summary and a large number of exercises.
