  • Research on ion channels has exploded in the last few decades and it is now clear that ion channels play essential roles in cell biology and physiology, with their dysfunction being the root cause of many human diseases. Understanding human biology in the post-genome sequencing era requires that the function of the protein products encoded by these recently sequenced genes be quantified.

  • 3D Channel effects read and manipulate the additional channels of information, includingz- depth, surface normals, object ID, texture coordinates, background color, unclamped RGB, and material ID. You can matte 3D elements along a z axis, insert other elements in a 3D scene, blur areas in a 3D scene, isolate 3D elements, apply a foggy effect with depth, and extract 3D channel information for use as parameters in other effects.

  • Sounding, Sampling and Simulation In the earlier chapters we discussed the characteristics of mobile radio channels in some detail. It emerged that there are certain parameters which provide an adequate description of the channel and it remains now to describe measuring equipment (channel sounders) that can be used to obtain experimental data from which these parameters can be derived.

  • The local media action plan set out the Government‘s thinking earlier this year on how it could enable a new market of local TV services. The action plan was largely a consultative exercise that considered the principles of local TV. It discussed the options the Government could take to incentivise the market, such as changing the wider regulatory structures or other steps to help create a new framework for local TV.

  • The idea of the role of various ICTs to communicate information was further developed in the follow-up research (R8347), in which respondents were asked to rank the importance of types of information pertinent to rural livelihoods. It can be seen from Table 7 and Table 8 that there is a great deal of similarity in the types of information regarded as most important in both countries. Note that priority information needs tend to relate to social matters.

  • To set up a Fast Etherchannel we must configure each of the ports exactly the same. They must be in the same VLAN, the same spanning tree parameters, the same duplex method, the same speed, and so forth. There is also one other requirement that is difficult to obtain from documentation, ALL PORTS IN THE CHANNEL CANNOT BE TRUNKS. If any of the ports we wish to configure in the Channel are set to trunk the Channel will not work. This does not mean we cannot trunk over the Fast Etherchannel, it simply means we must set up trunking after...

  • Parameter Synchronization for Flat Fading Channels In Chapters 14 and 15, important aspects of digital receiver synchronization for fading channels are discussed. The two sections of Chapter 14 concentrate on linear sync parameter estimation for the flat fading case, i.e., flat fading channel estimation. The derivation of many of the algorithms presented here draws from the ideas and results of Chapter 12.

  • Estimation theory gives one approach to characterizing random variables. This was based on building parametric models and describing the data by the parameters. An alternative approach is given by information theory. Here the emphasis is on coding. We want to code the observations. The observations can then be stored in the memory of a computer, or transmitted by a communications channel, for example.

  • Mobile Satellite Communication∗ In principle communications satellites provide the same connectivity as terrestrial (wireless and wireline) networks. The advantages of satellites, such as fast wide-area coverage, flexible transmission parameters and cost independence due to distance, are compared with the disadvantages, such as restricted channel capacity because of the frequencies available, orbital positions, need for line-of-sight connectivity and high initial investment besides relatively long signal propagation times.

  • The increasing demand for communications services and the desire for increased data throughput in modern communications systems has fueled research and development into the use of adaptive antenna arrays. Since frequency bandwidth is in short supply and is expensive to acquire, the ability to separate users based on their spatial parameters is very attractive for wireless networks. Adaptive antenna arrays offer the ability to increase the Signal-to-Noise Ratio (SNR) of a wireless communication link while at the same time permit the cancellation and removal of co-channel interference. ...
