This paper describes recent development in the Webclopedia QA system, focusing on the use of knowledge resources such as WordNet and a QA typology to improve the basic operations of candidate answer retrieval, ranking, and answer matching.

the first step in mining activities is rock excavation in both mine development and production. constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

We demonstrate aberration-free dynamic focusing with a low-cost 19-channel continuous-surface micromachined membrane deformable mirror (MMDM). A lookup table of the optimum control voltages for various focal lengths is obtained with an adaptive optics algorithm. Diffraction-limited imaging resolution is achieved owing to the capability of the MMDM for aberration compensation. The measured speed...

This paper aims at explaining how to follow an agent-oriented process to develop a multi-agent mechanism design system. ADELFE methodology is devoted to adaptive multi-agent systems in which adaptation is enabled by cooperative self-organization. Two main works are emphasized. First, the analysis leads to the agent identification by studying the interactions both between the system and its envi...

Booth encoded Multiplier is used to reduce the hardware utilization in chip level designing in VLSI projects. The present project is focusing on designing and developing a powerful Booth encoded multiplier integrated with Carry Select Adder [CSLA]. Primarily the on hand Booth encoding multiplier is used in multiplication operations based on signed numbers only. The multipliers such as braun arr...

this study intended to carry out a survey of engineering college libraries that have computerized their operations and services. it provides an implicit view of the professional experiences of the engineering college librarians in computerizing their house keeping operations. information was collected using a structured questionnaire mailed to 128 engineering college librarians, of which 102 (7...
