Static mixers are an attractive alternative for the mixing of chemicals in water treatment plants. The attraction comes from the fact that static mixers do not require an external input of energy and do not have moving parts. Static mixers consist of mixing elements fixed on the inside of a pipe of channel. The elements do not move. Chemicals, added just upstream of the mixers, mix with the bulk fluid because of the complex, three-dimensional fluid motion generated by the elements. The goal of this project is to explore the use of static mixers in two of the key processes in drinking water treatment: for the mixing of coagulants for destabilization and the mixing of disinfectants for the inactivation of Cryptosporidium parvum oocysts in disinfection. The role of mixing in both of these processes is not well understood. But for each process experimental and theoretical evidence suggests that, at least in some circumstances, the mixing environment provided when chemicals are introduced into the flow will affect the resulting destabilization or inactivation.

Far too many programmers and software designers consider efficient C++ to be an oxymoron. They regard C++ as inherently slow and inappropriate for performance-critical applications. Consequently, C++ has had little success penetrating domains such as networking, operating system kernels, device drivers, and others. "Efficient C++" explodes that myth. Written by two authors with first-hand experience wringing the last ounce of performance from commercial C++ applications, this book demonstrates the potential of C++ to produce highly efficient programs. The book reveals practical, everyday object-oriented design principles and C++ coding techniques that can yield large performance improvements. It points out common pitfalls in both design and code that generate hidden operating costs. This book focuses on combining C++'s power and flexibility with high performance and scalability, resulting in the best of both worlds. Specific topics include temporary objects, memory management, templates, inheritance, virtual functions, inlining, reference-counting, STL, and much more. With this book, you will have a valuable compendium of the best performance techniques at your fingertips. 0201379503B04062001

This book is devoted to the discussion and studies of simple and efficient numerical procedures for large deflection and elasto-plastic analysis of steel frames under static and dynamic loading. In chapter 1, the basic fundamental behaviour and philosophy for design of structural steel is discussed, emphasising different modes of buckling and the inter-relationship between different types of analysis. In addition to this, different levels of refinement for non-linear analysis are described. An introduction is also given to the well-known P-&dgr; and P-&Dgr; effects. Chapter 2 presents the basic matrix method of analysis and gives several examples of linear analysis of semi-rigid pointed frames. It is evident from this that one must have a good understanding of first-order linear analysis before handling a second-order non-linear analysis. In chapter 3, the linearized bifurcation and second-order large deflection are compared and the detailed procedure for a second-order analysis based on the Newton-Raphson scheme is described. Chapter 4 introduces various solution schemes for tracing of post-buckling equilibrium paths and the Minimum Residual Displacement control method with arc-length load step control is employed for the post-buckling analysis of two and three dimensional structures. Chapter 5 addresses the non-linear behaviour and modelling of semi-rigid connections while several numerical functions for description of moment versus rotation curves of typical connection types are introduced. The scope of the work in chapter 6 covers semi-rigid connections and material yielding to the static analysis of steel frames. Chapter 7 studies the cyclic response of steel frames with semi-rigid joints and elastic material characteristics. In the last chapter the combined effects of semi-rigid connections and plastic hinges on steel frames under time-dependent loads are studied using a simple springs-in-series model. For computational effectiveness and efficiency, the concentrated plastic hinge concept is used throughout these studies.

Among the known disinfectants, ozone has been demonstrated to be very effective in inactivating protozoans. Current and proposed regulations impose additional treatment requirements for Cryptosporidium parvum . These regulatory trends tend to place more stringent performance demands on disinfection systems and have therefore increased the need for improvements in the design. The static mixer offers one alternative method for improving the efficiency of the dissolution of ozone and optimizing its use in the disinfection process. The overall objective of this research was to quantify the potential benefits of ozone application through the use of static mixers in terms of increased transfer efficiency, disinfection capacity, and enhanced chemical reactions at laboratory-, pilot-, and full-scale systems. Specific goals were to identify and quantify the effect of several water quality parameters and environmental/engineered factors on the disinfection capacity of the ozone-static mixer system and assess bromate formation under optimum conditions for microbial inactivation.The results showed that a static mixer provided (1) rapid and efficient dissolution of gaseous ozone and (2) generation of a homogeneous dissolved ozone solution. These conditions led to higher CTs resulting in enhanced inactivation as compared to fine bubble diffusion contactors. It was found that a static mixer, when integrated with a well-designed, continuous-plug flow ozone contactor, could achieve excellent and predictable Cryptosporidium parvum inactivation. In such systems, applying low ozone doses (GBP 0.5 mg O3/mg C) combined with a pH of GBP 7.0 can provide adequate microbial inactivation while keeping bromate formation below the current MCL (10 ppb.

When Curtis Brooks starts receiving phone calls from his older brother Wilt, who’s been dead a week, he’s sure it’s to help him find evidence that will lead to a murderer’s arrest. But Wilt claims he wasn’t murdered; his calling, meant to help him adjust, is standard protocol for newly deceased at the Aftermart--a kind of inescapable, ever-expanding Walmart filled with discontinued products. Wilt’s death ruled a homicide, Curtis embarks on a dangerous plan to find the killer, which soon has him scheming against a billionaire and floundering toward love with his brother’s ex-girlfriend Suzy, all while struggling through high school and his single mom’s poor choices. Why does Wilt help Curtis win over Suzy, even as he organizes a rebellion at the Aftermart? Who’d wanted him dead? Curtis risks his life to answer these questions, in the process forging a bond with his brother unlike any they’ve ever had.

Optimal control theory is a technique being used increasingly by academic economists to study problems involving optimal decisions in a multi-period framework. This book is designed to make the difficult subject of optimal control theory easily accessible to economists while at the same time maintaining rigor. Economic intuition is emphasized, examples and problem sets covering a wide range of applications in economics are provided, theorems are clearly stated and their proofs are carefully explained. The development of the text is gradual and fully integrated, beginning with the simple formulations and progressing to advanced topics. Optimal control theory is introduced directly, without recourse to the calculus of variations, and the connection with the latter and with dynamic programming is explained in a separate chapter. Also, the book draws the parallel between optimal control theory and static optimization. No previous knowledge of differential equations is required.

This book is concerned with the static and dynamic analysis of structures. Specifi cally, it uses the stiffness formulated matrix methods for use on computers to tackle some of the fundamental problems facing engineers in structural mechanics. This is done by covering the Mechanics of Structures, its rephrasing in terms of the Matrix Methods, and then their Computational implementation, all within a cohesivesetting. Although this book is designed primarily as a text for use at the upper-undergraduate and beginning graduate level, many practicing structural engineers will find it useful as a reference and self-study guide. Several dozen books on structural mechanics and as many on matrix methods are currently available. A natural question to ask is why another text? An odd devel opment has occurred in engineering in recent years that can serve as a backdrop to why this book was written. With the widespread availability and use of comput ers, today's engineers have on their desk tops an analysis capability undreamt of by previous generations. However, the ever increasing quality and range of capabilities of commercially available software packages has divided the engineering profession into two groups: a small group of specialist program writers that know the ins and outs of the coding, algorithms, and solution strategies; and a much larger group of practicing engineers who use the programs. It is possible for this latter group to use this enormous power without really knowing anything of its source.

iming, timing, timing! That is the main concern of a digital designer charged with designing a semiconductor chip. What is it, how is it T described, and how does one verify it? The design team of a large digital design may spend months architecting and iterating the design to achieve the required timing target. Besides functional verification, the t- ing closure is the major milestone which dictates when a chip can be - leased to the semiconductor foundry for fabrication. This book addresses the timing verification using static timing analysis for nanometer designs. The book has originated from many years of our working in the area of timing verification for complex nanometer designs. We have come across many design engineers trying to learn the background and various aspects of static timing analysis. Unfortunately, there is no book currently ava- able that can be used by a working engineer to get acquainted with the - tails of static timing analysis. The chip designers lack a central reference for information on timing, that covers the basics to the advanced timing veri- cation procedures and techniques.

Embedded memories are one of the fastest growing segments oftoday's new technology market. According to the 2001 InternationalTechnology Roadmap for Semiconductors, embedded memories will continueto dominate the increasing system on chip (SoC) content in the nextseveral years, approaching 94% of the SoC area in about 10 years.Furthermore, the shrinking size of manufacturing structures makesmemories more sensitive to defects. Consequently, the memory yieldwill have a dramatic impact on the overall Defect-per-million level, hence on the overall SoC yield. Meeting a high memory yield requiresunderstanding memory designs, modeling their faulty behaviors, designing adequate tests and diagnosis algorithms as well as efficientself-test and repair schemes."Testing Static Random Access Memories" covers testing of one ofthe important semiconductor memories types; it address testing ofstatic random access memories (SRAMs), both single-port andmulti-port. It contributes to the technical acknowledge needed bythose involved in memory testing, engineers and researchers. The bookbegins with outlining the most popular SRAMs architectures. Then, thedescription of realistic fault models, based on defect injection andSPICE simulation, are introduced. Thereafter, high quality and lowcost test patterns, as well as test strategies for single-port, two-port and any p-port SRAMs are presented, together with somepreliminary test results showing the importance of the new tests inreducing DPM level. The impact of the port restrictions (e.g., read-only ports) on the fault models, tests, and test strategies isalso discussed.Features:
