The main links with your PC and the outside world are the centronic port, used for connecting the printer, the RS232 port, used for the mouse, and the games port for a joystick. This book explores how these input/output (I/O) ports can be put to use through a range of other interfacing applications. This is especially useful for laptop and palmtop PCs which cannot be fitted with internal I/O cards. A novel approach is taken by this book, combining the hardware through which the ports can be explored, and the software programming needed to carry out a range of experiments. Circuits are provided for simple testing tools, and three experimental boards - which can also be purchased ready-made. Ready-to-run TurboPascal programs are available on the Newnes web site. A huge range of applications... Less

It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new... Less

In the early days of computing, technicians in white coats controlled refrigerator- sized computers housed in sealed rooms, far from ordinary users. Today, computers are inexpensive commodities, like television sets,and ordinary people control and interact with them. This new paradigm has led to a burgeoning demand for graphics- intensive and highly interactive interfaces. Developing User Interfaces is targeted at the programmer who will actually implement, rather than design, the user interface. Most user interface books focus on psychology and usability, not programming techniques. This book recognizes the need for programmers to collaborate with usability experts and psychologists, so topics such as the principles of visualization, human perception, and usability evaluation are touched...

In the small world of micrometer to nanometer scale many natural and industrial processes include attachment of colloid particles (solid spheres, liquid droplets, gas bubbles or protein macromolecules) to fluid interfaces and their confinement in liquid films. This may lead to the appearance of lateral interactions between particles at interfaces, or between inclusions in phospholipid membranes, followed eventually by the formation of two-dimensional ordered arrays. The book is devoted to the description of such processes, their consecutive stages, and to the investigation of the underlying physico-chemical mechanisms. The first six chapters give a concise but informative introduction to the basic knowledge in surface and colloid science, which includes both traditional concepts and some... Less
