The world is changing distinctly and manufacturing is facing significant challenges. Current manufacturing paradigms need to develop towards better agility to meet current market demand. The relevant research has been launched and the resulting new approaches, like smart manufacturing, digital manufacturing and the cognitive factory, are introduced. However, today’s real challenge to manufactur...

Empirical optimizers like ATLAS have been very effective in optimizing computational kernels in libraries. The best choice of parameters such as tile size and degree of loop unrolling is determined by executing different versions of the computation. In contrast, optimizing compilers use a model-driven approach to program transformation. While the model-driven approach of optimizing compilers is...

This research uses object-oriented simulation to derive the migratory patterns of animal populations. These patterns are then compared with the trajectories of aquatic pollutant releases to yield quantitative biological impact assessments. These estimates are more realistic than those based on assumptions of uniform or random distributions of animals in a region--a common approach to this probl...

In model reference control, the objective is to design a controller such that the closed-loop system resembles a reference model. In the standard model-based solution, a plant model replaces the unknown plant in the design phase. The norm of the error between the controlled plant model and the reference model is minimized. The order of the resulting controller depends on the order of the plant ...

this study aimed to identify and test expectancy motivational model as a theoretical framework to explain the reasons motivating expected information consumer’s behavior for the selection and use of document delivery services of shahid chamran university, ahvaz. in this study, explanatory survey method was used. in order to test the hypotheses and analysis of model’s data, covariance structural...

In den letzten Jahren hat die von der OMG proklamierte, modellgetriebene Softwareentwicklung Model Driven Architecture (MDA) bzw. das Model Driven Engineering (MDE) in vielen Bereichen der Informatik an Bedeutung gewonnen. Bei diesem Vorgehen steht das Modell des zu realisierenden Systems im Vordergrund, welches iterativ mittels geeigneter Werkzeuge und Sprachen erstellt und präzisiert wird. Ab...

As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...

water is the most essential component for sustaining lives of humans and other living creatures. supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. but sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. th...
