60GHz wireless communication is a promising technology for multi-gigabit communication in future home networks. It brings possibility of achieving in-door high-definition multimedia applications with high-speed and low-delay experience. However, to maintain the network connectivity with 60GHz links, which are susceptible to propagation and penetration losses, is a major challenge. The quality and robustness of 60GHz links can be effectively improved by employing relay nodes or cooperative nodes in the network. In this paper, taking into consideration the directional transmission character of 60GHz system, we conduct performance analysis and simulations for the 60GHz cooperative communication system. Two cooperative forwarding approaches are analyzed and compared, and the optimal position of the cooperative relay node is proposed.

<p>Este artículo presenta los resultados de diseño y evaluación del desempeño de una red de comunicaciones para Medición Inteligente o AMI (<em>Advanced Metering Infrastructure</em>), empleando el simulador de redes <em>Network Simulator</em>-2 (NS-2). La red de comunicaciones propuesta combina las tecnologías PLC (<em>PowerLine Communication</em>) y HSDPA (<em>High Speed Downlin Packet Access</em>), así como el uso de concentradores de datos (DCs) y de protocolos aplicación y transporte como DLMS/COSEM y TCP-UDP/IP. Los resultados de evaluación indicaron que al introducir dispositivos DCs dentro del diseño de red de comunicaciones, la red presenta un desempeño superior frente a otras que no emplean DCs para concentrar la información de diferentes medidores inteligentes. Finalmente, se observó una mayor cobertura y un menor número de acceso directos a la red de comunicaciones al considerar DCs en el diseño.</p>

This chapter considers how media landscapes in the home have shifted over this century and examines how devices relate to each other and to householders to create dynamic and evolving media ecologies. At the turn of this century, a typical domestic media ecology comprised a cathode-ray television in the living room, perhaps connected to a videocassette recorder; a desktop computer in a home office, perhaps connected to a dial-up modem; and a landline telephone, often located in a communal area in the home. More recently, the home has become a place for high-definition “smart” televisions, intelligent multifunction set-top boxes, game consoles, digital radio, high-speed broadband, cabled and wireless home networks, mobile computing, cloud connections, online government service provision, gesture-controlled games, and much more. How and why have these technologies been appropriated? How has this ongoing appropriation reconfigured the domestic media ecology and the life that is lived within this ecology?

Circuit Function

Most microelectronics devices and circuits operate faster, consume less power, execute more functions and cost less per circuit function when the feature-sizes internal to the devices and circuits are made smaller. This is part of the stimulus for the Very High-Speed Integrated Circuits (VHSIC) program. There is also a need for smaller, more sensitive sensors in a wide range of disciplines that includes electrochemistry, neurophysiology and ultra-high pressure solid state research. There is often fundamental new science (and sometimes new technology) to be revealed (and used) when a basic parameter such as size is extended to new dimensions, as is evident at the two extremes of smallness and largeness, high energy particle physics and cosmology, respectively. However, there is also a very important intermediate domain of size that spans from the diameter of a small cluster of atoms up to near one micrometer which may also have just as profound effects on society as “big” physics.

One of the most important requirements for a high-performance EM, especially an analytical EM using a fine beam probe, is to prevent specimen contamination by providing a clean high vacuum in the vicinity of the specimen. However, in almost all commercial EMs, the pressure in the vicinity of the specimen under observation is usually more than ten times higher than the pressure measured at the punping line. The EM column inevitably requires the use of greased Viton O-rings for fine movement, and specimens and films need to be exchanged frequently and several attachments may also be exchanged. For these reasons, a high speed pumping system, as well as a clean vacuum system, is now required. A newly developed electron microscope, the JEM-100CX features clean high vacuum in the vicinity of the specimen, realized by the use of a CASCADE type diffusion pump system which has been essentially improved over its predeces- sorD employed on the JEM-100C.
