A timely and comprehensive reference guide for IC designers dealing with the increasingly widespread demand for integrated low power management Includes new topics such as LED lighting, fast transient response, DVS-tracking and design with advanced technology nodes Leading author (Chen) is an active and renowned contributor to the power management IC design field, and has extensive industry experience Accompanying website includes presentation files with book illustrations, lecture notes, simulation circuits, solution manuals, instructors’ manuals, and program downloads
LTE Services
LTE (Long Term Evolution) is commonly marketed as 4G. LTE and LTE Advanced have been recognized by ITU-R and ITU-T (International Telecommunications Union – Telecommunications) as the principal solution for the future mobile communication networks standards. They are thus the framework of what the marketing calls 4G and possibly also 5G. This book describes various aspects of LTE as well as the change of paradigm, which it is bringing to mobile communications, focusing on LTE standards and architecture, OFDMA, the Full IP Core Network and LTE security.
Polymer Extrusion
Extrusion is by far the most important and the oldest processing and shaping method for thermoplastic polymers. This process concerns almost all synthetic polymers, as well as elastomers or food materials. Single-screw extrusion is mainly used nowadays to manufacture finished goods or semi-finished products. More than 90 million tons of thermoplastics are therefore processed every year. Twin-screw extrusion may be divided into two systems: contra-rotating systems used within the context of PVC extrusion, for the manufacture of pipes or profiles; and co-rotating systems experiencing nowadays a very significant development, because of their significant adaptability and flexibility, which enables the manufacture of specific materials (polymer alloys, thermoplastic elastomers, filled polymers, nanocomposites). Extrusion is carried out by passing molten polymer through a tool called die that will give the product its final shape (films and sheets, rolled products, and electric cables). Thanks to the design of dies, we obtain at the output a product with controlled dimensions, uniform speeds and homogeneous temperatures. The book will discuss the same production types, but only in the case of coextrusion flows, i.e. multilayer stratified products. First of all, we will present in this book the physics of the mechanisms at stake, then propose more or less complex models in order to describe these mechanisms and then go forward in the interpretation of results and the control of condition flows.
Highway Engineering
The repair, renovation and replacement of highway infrastructure, along with the provision of new highways, is a core element of civil engineering, so this book covers basic theory and practice in sufficient depth to provide a solid grounding to students of civil engineering and trainee practitioners. Moves in a logical sequence from the planning and economic justification for a highway, through the geometric design and traffic analysis of highway links and intersections, to the design and maintenance of both flexible and rigid pavements Covers geometric alignment of highways, junction and pavement design, structural design and pavement maintenance Includes detailed discussions of traffic analysis and the economic appraisal of projects Makes frequent reference to the Department of Transport’s Design Manual for Roads and Bridges Places the provision of roads and motorways in context by introducing the economic, political, social and administrative dimensions of the subject
Building Procurement
As an industrial process, construction is unique in that the method of procurement of any built asset (building, infrastructure or process plant) defines many of the subsequent management processes that take place during the building phase – a very different situation to the purchase of goods and services in most other industries. The procurement process is therefore central to the success of any construction project and many of the problems which impact construction projects can be traced back to the procurement phase, so a good understanding of the methods of procurement and the influence it has on project success is essential for all those working in the industry. Much has changed in the global construction industry since publication of the first edition of Building Procurement, for example the global liquidity & banking crisis and the debt burden of many major economies. This new edition has been rewritten to take account of these significant developments, but at its core it continues to provide a critical examination and review of current procurement practices in the UK, continental Europe (including EU procurement procedures), China and the USA. It retains its original strong emphasis on the need for clients to establish achievable objectives which reflect the project business case and focuses on development of suitable strategies and management structures to meet those objectives in the current construction climate. Building Procurement will be essential reading for senior undergraduate and postgraduate students of construction management and practitioners working in all areas of construction management. Review of the first edition «…a thorough and comprehensive investigation of building procurement…» Construction Management and Economics
