The effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. The third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. Equations of motion of the plate are obtained with the help of calculus of variation. Parametric study ...

Scientific support depot location and reasonable spare parts transportation are the keys to improving level of complex systems. The current equipment system has problems chaotic warehouse layout low efficiency parts. reliability completeness parts’ historical data hard believe. In order deal with cognitive uncertainty caused by asymmetry data, this paper adopts theory optimize volume. Under con...

The sparse nature of location finding in the spatial domain makes it possible to exploit the compressive sensing (CS) theory for wireless location. CS-based location algorithm can largely reduce the number of measurements while achieve a high level of localization accuracy, which makes the CS-based solution very attractive for indoor positioning. In this paper, a novel CS-based fingerprinting l...

Information systems open up a broad range of possibilities for new forms of organization and electronic business on a global scale. Traditional organizational boundaries are dissolving and new organizational forms are emerging. Business “any time & any place” often seems to be the logical consequence. The gradual dissolution of temporal and spatial constraints in business processes, however, pa...
