  • This, as befits a first chapter in a book on Tomcat, is a short history of dynamic web content and how Tomcat fits into that history. Once you’ve dealt with that, you’ll learn about Tomcat’s architecture and its modular approach to configuration. The Web isn’t solely made up of static pages that show the same document to every user; many pages contain content generated independently for each viewer. Although static files still have their place, many useful and necessary web sites would be unable to function without dynamic content....

  • Concrete has been in use as a primary building material since Roman times. As it is strong in compression but weak in tension, it was used in arches, vaults and walls where it is stressed principally in compression. In the mid-nineteenth century, it was discovered that iron and later steel bars could be embedded in the concrete, effectively giving it tensile strength. This allowed it to be used in beams and slabs, where it worked in bending. Buildings, bridges, retaining walls and many other structures were made in this reinforced concrete.

  • Heat transfer is a fundamental part of thermal engineering. It is the science of the rules governing the transfer of heat between systems of different temperatures. In thermodynamics, the heat transferred from one system to its surroundings is assumed as a given process parameter. This assumption does not give any information on how the heat is transferred and which rules determine the quantity of the transferred heat. Heat transfer describes the dependencies of the heat transfer rate from a corresponding temperature difference and other physical conditions....

  • Cell membranes act as barriers to most, but not all, molecules. The development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell. Cell membranes are differentially (or semi-) permeable barriers separating the inner cellular environment from the outer cellular (or external) environment.

  • Chapter 1 is for readers who have less background in partial differential equations (PDEs). It contains materials which will be useful in understanding some of the jargon related to the rest of the chapters in this book. A discussion about the classification of the PDEs is presented. Here, we outline the major analytical methods. Later in the chapter, we introduce the most important numerical techniques, namely the finite difference method and finite element method. In the last section we briefly introduce the level set method.

  • The state-of-the-art of controlled radical polymerization (CRP) in 2011 is presented. Atom transfer radical polymerization, stable radical mediated polymerization, and degenerate transfer processes, including reversible addition fragmentation chain transfer are the most often used CRP procedures. CRP opens new avenues to novel materials from a large range of monomers. Detailed structure-reactivity relationships and mechanistic understanding not only helps attain a better controlled polymerization but enables preparation of polymers with complex architectures.

  • Summary of Mechanics 0) The laws of mechanics apply to any collection of material or ‘body.’ This body could be the overall system of study or any part of it. In the equations below, the forces and moments are those that show on a free body diagram. Interacting bodies cause equal and opposite forces and moments on each other. Linear Momentum Balance (LMB)/Force Balance ˙ Equation of Motion Fi = L t2 t1 I) The total force on a body is equal to its rate of change of linear momentum. L Net impulse is equal to the change in momentum. When there is no...

  • There are many different types of upholstered chairs and sofas, and they vary widely in quality. Most of the quality characteristics are similar for all upholstered items. There are, however, a few home furnishing items such as recliners and sleeper sofas that have additional quality characteristics. A high price tag does not necessarily indicate quality. High-quality and low-quality upholstered furniture can be found in all price ranges. High-quality upholstery is difficult to evaluate because you cannot see inside the furniture. There are, however, methods of determining quality.

  • It has long been recognised that an appreciation of the role of structure is essential to the understanding of architecture. It was Vitruvius, writing at the time of the founding of the Roman Empire, who identified the three basic components of architecture as firmitas, utilitas and venustas and Sir Henry Wooton, in the seventeenth century1, who translated these as ‘firmness’, ‘commodity’ and ‘delight’.

  • It can be argued that no company has dominated its own little portion of computer networking as completely as Cisco Systems. Market research has estimated that 70 percent of the Internet runs on Cisco hardware. This is an amazing statistic when you consider the number of manufacturers vying for market share in this arena. To put this number in perspective, imagine that seven out of every ten cars on the highway today were produced by a single car manufacturer. Why is Cisco hardware so popular? First and foremost is reliability.
