  • One of the major challenges in TRECstyle question-answering (QA) is to overcome the mismatch in the lexical representations in the query space and document space. This is particularly severe in QA as exact answers, rather than documents, are required in response to questions. Most current approaches overcome the mismatch problem by employing either data redundancy strategy through the use of Web or linguistic resources. This paper investigates the integration of lexical relations and Web knowledge to tackle this problem.

  • Freeform fabrication technology does not require pre-formed mandrels or tooling; instead, it builds physical objects directly from computer graphical data. This type of technology is also known as layer manufacturing, since it constructs the three- dimensional object layer by layer (Jacobs, 1992; Beaman et al., 1997). The technology has proved that it can help to rapidly provide feedback on design concepts, discover inconsistencies in the design, modify the design, and eliminate inconsistency before fabricating the design.

  • Aluminium alloys have undergone a dramatic transformation in areas of extrusion, machining, welding, heat treatment, structural changes, created by ultra fine particles and enhanced corrosion resistance. Hence, these alloys have made rapid gains in European automotive and space industry. These developments have been described by experts in the book with new data and attractive graphics. The effect of processing parameters, including welding and deep rolling on their performance have been highlighted to alleviate the concerns of manufacturers and designers for new applications.

  • Information Technology, which is one of global competitive technologies in Korea, was introduced to utilize the production area more efficiently. Chang (2006) has reported a using of a wireless internet environment and PDA system to exchange real time information data between the workers. Shin (2006) has presented a prototype of block tracking system for pre-erection area using of PDA and GPS to chase the location of each block and to exchange the pre-erection work order.

  • Because the photopolymer used in the SL process tends to curl or sag as it cures, models with overhangs or unsupported horizontal sections must be reinforced with supporting structures: walls, gussets, or columns. Without support, parts of the model can sag or break off before the polymer has fully set. Provision for forming these supports is included in the digitized fabrication data. Each scan of the laser forms support layers where necessary while forming the layers of the model.

  • The hole closing reported in this letter is certainly not caused by deposition of carbon-rich material by the electron beam, a common phenomenon in electron microscopy. The observation that large pores expand is in direct contradiction with potential contamination growth. Secondly, electron-energy-loss spectra (EELS) locally obtained on the material that filled a nanopore clearly show the presence of silicon and oxygen,but the absence of any carbon (detection limit was less than 2%).

  • It is inconceivable today to imagine designing buildings without the use of computers. They are used at every step of the architectural process, from conceptual design to construction. Three­ dimensional modeling and visualization, generative form finding, scripted modulation systems, structura and thermal analyses, project management and coordination, and file-to-factory production are just some of the digital practices employed by architects and building consultants.

  • Phase diagrams, thermodynamic data in graphical form, are one of the basic tools of the metallurgist, materials scientist, and materials engineer. They can be used for alloy design, selection of hot-working and fabricating parameters, prediction of performance, guidance in selection of hot-working and fabricating parameters, prediction of performance, guidance in selection of heat-treating process parameters, solving performance problems, including failure analysis, and for many other purposes.

  • The fundamental aim of microengineering — to take a design from a computer aided design (CAD) software package and manifest it in a physical manner — may be achieved through one of a number of different fabrication or micromachining technologies. Many of these technologies employ a process known generally as photolithography , or a variation of this process, to transfer a two-dimensional pattern from a mask into the structural material.
