This paper presents a scheduling model for computer music systems. We give an overview of planning and scheduling issues in computer-aided music creation and rendering, and propose strategies for executing actions and computations in music composition or performance contexts. Introduction It is well known that the notion of scheduling can imply different levels and complexity in planning tasks ...

Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...

Tight time and cost constraints force chemical process industries to continuously reduce their experimental effort during chemical process development and to facilitate the application of model-based process technology. Nevertheless, the effort of setting up a detailed mathematical model for a chemical process remains still high due to the large variety of chemical process units and physical ph...

As the complexity of systems increase, the need for computer-aided techniques in software system definition, design, ·and construction becomes apparent. It is the ultimate task of software engineering to develop tools and procedures which reduce the effort invol ved in production of effective software. Effective software must possess characteristics of correctness, reliability, efficiency, docu...

This paper describes an expert system that helps designers select a manufacturing process in the early stage of product design. First, the paper focuses on net-shape manufacturing processes and identifies the major factors that affect the selection of an appropriate process. Examples of these factors include shape, production volume, and material. A versatile methodology should consider all the...

The selection of proper materials for different components is one of the most challenging tasks in engineer’s activity. The traditional approach to the selection of materials required looking through the literature and material safty data sheets.With the development of information technology, engineering work has also changed. It involves not only arduous browsing catalogues and guides but also...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...

Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...
