With the rapid growth of the wireless mobile applications, wireless voice has begun to challenge wireline voice, whereas the desire to access e-mail, surf the Web or download music (e.g., MP3) wirelessly is increasing for wireless data. While second generation (2G) cellular wireless systems, such as cdmaOne1, GSM2 and TDMA3, introduced digital technology to wireless cellular systems to deal with the increasing demand for wireless applications, there is still the need for more spectrally efficient technologies for two reasons. First, wireless voice capacity is expected to continue to grow. Second, the introduction of high-speed wireless data will require more bandwidth.

District energy (DE) systems use central heating and/or cooling facilities to provide heating and/or cooling services for communities. The advantages of district energy over conventional heating and cooling include improved efficiency, reliability and safety, reduced environmental impact, and for many situations better economics. DE systems can be particularly beneficial when integrated with cogeneration plants for electricity and heat, i.e., with combined heat and power (CHP) plants. One of the main impediments to increased use of cogeneration-based district energy is a lack of understanding of the behavior of integrated forms of such systems. This book is aimed at providing information on district energy and cogeneration tech- nologies, as well as systems that combine them.

为Delphi2005做了改动 DSPack 2.3.3 (Sep 2004). DSPack is a set of Components and class to write Multimedia Applications using MS Direct Show and DirectX technologies. DSPack is designed to work with DirectX 9 on Win9X, ME, 2000, and Windows XP operating systems. Now VMR (Video Mixing Renderer) is available on all Windows Operating Systems. DSPack 2 is designed to work with Delphi 5,6,7 and CPP Builder 6.

We propose and analyze several timestamping of an MPEG-2 Transport Stream transmitted strategies for performing over a packet-switched network using the PCR-unaware encapsulation scheme, and analyze their effect on the quality of the recovered clock at the MPEG-2 Systems decoder.

The original NuLib has been ported to many different systems. Version 3.2.5 is functionally similar to v3.2.4, but the source code and documentation were cleaned up by Devin Reade, making it easier to build. NuLib2 is generally superior, but NuLib does have the advantage of running under 16-bit MS-DOS and GS/OS.

In case you haven t realized it, building computer systems is hard. As the complexity of the system gets greater, the task of building the software gets exponentially harder. As in any profession, we can progress only by learning, both from our mistakes and from our successes. This book represents some of this learning written in a form that I hope will help you to learn these lessons quicker than I did, or to communicate to others more effectively than I did before I boiled these patterns down.

This is an example how one could hide a process on Windows based operation systems from task viewers like ProcDump (G-RoM, Lorian & Stone) or ProcessExplorer (SysInternals). It could e.g. be used as some kind of dump protection. The way to get this done is very different on NT and 9x machines.
