Traditionally, multiple IC chips are needed to build transmitters (Tx) used in wireless communications. The difficulty with a full Tx integration is that each Tx building block uses different technology. A power-detection circuit will exploit the Schottky diode, while the modulator IC is integrated with BiCMOS or SiGe. Likewise, the digital control loop is implemented in CMOS. Now that directco...

Due to climate change energy efficiency is becoming increasingly important. This is particularly true for the building system control sector, where a large energy saving potential exists. Model Predictive Control (MPC) is a new control technique in this sector that minimises the building energy use while taking into account comfort and other constraints through the use of a simplified building ...

The widespread use of building integrated photovoltaics appears likely as a result of the continuing decline in photovoltaic manufacturing costs, the relative ease in which photovoltaics can be incorporated within the building envelope, and the fact that buildings account for over 40 percent of the U.S. energy consumption. However, designers, architects, installers, and consumers need more info...

The major motivation for database programming language (DBPL) research is to facilitate the construction and maintenance of large dataintensive applications. To fully bene t from DBPLs, supporting methodologies and tools are needed. This paper reports requirements for such methodologies and tools that were experienced when constructing a multiauthored, multi-levelled Thesaurus Application (TA) ...

Knowledge base building environments must progress in two important directions: (i) increased participation of domain experts in the knowledge design process through new computational models and effective man-machine interfaces; and (ii) automated knowledge acquisition tools to facilitate the overt expression of knowledge. This paper presents the integration of a knowledge acquisition methodolo...

Operating a building efficiently means co-ordinating the physical plants with constantly changing needs. Building energy management is performed in different ways, on European scale, since design, manufacture, engineering, installation, commissioning and maintenance processes are contemporary involved, and it reflects the wide variations in climate, building type, space per capita, control and ...
