Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

Swarm based techniques have huge application domain covering multiple disciplines, which include power system, fuzzy system, forecasting, bio-medicine, sociological analysis, image processing, sound processing, signal processing, data analysis, process modeling, process controlling etc. In last two decades numerous techniques and their variations have been developed. Despite many variations are...

In computer vision to create a knowledge base usable by information systems, we need a data structure facilitating the information access. Artificial intelligence community uses the ontologies to structure and represent the domain knowledge. This information structure can be used as a database of many geographic information systems (GIS) or information systems treating real objects for example ...

This paper introduces an eecient indexing organization which provides for parallel retrievals. Given a p-processor massively parallel computer, our organization allows a maximum of p retrievals to be performed concurrently and thus achieves an approximate speed up of p in the best case. The index structure is based on the multi-B-tree index structure. It is compatible with current automatic ret...

Resolving the excessive energy consumption of modern computer systems has become a substantial challenge. Therefore, various techniques have been proposed to reduce power dissipation and improve energy efficiency of computer systems. These techniques affect the energy efficiency across different layers in a system. In order to better understand and analyze those techniques, it is necessary to o...

< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

The properties of a two dimensional dynamical system are described. The structure of the system is explored through the study of t-lines and their images under the transformation operator, Φ6. The analysis of t-line, Lt, images leads to a closed form parametrization for the discriminant curve of the cubic. The parametrization, λ(s), is utilized to study the action of Φ6 on the discriminant curv...

We have developed a web server (ProteinDBS) for the life science community to search for similar protein tertiary structures in real time. This system applies computer visualization techniques to extract the predominant visual patterns encoded in two-dimensional distance matrices generated from the three-dimensional coordinates of protein chains. When meaningful contents, represented in a multi...
