results of different studies demonstrate that the world-class organizations have better performance in encountering challenges of twenty-first century. therefore developing such features is strongly recommended to iranian firms. most of experts believe that to achieve to world-class situation, the most important factor is marketing, and all organizations should assess themselves about world-cla...

Data in object-oriented programming is organized in a hierarchy of classes. The problem of object-oriented pattern matching is how to explore this hierarchy from the outside. This usually involves classifying objects by their run-time type, accessing their members, or determining some other characteristic of a group of objects. In this paper we compare six different pattern matching techniques:...

Locomotion in mammals is controlled by a spinal central pattern generator (CPG) coupled to a biomechanical limb system, with afferent feedback to the spinal circuits and CPG closing the control loop. We have considered a simplified model of this system, in which the CPG establishes a rhythm when a supra-spinal activating drive is present and afferent signals from a single-joint limb feed back t...

A Haskell program may fail at runtime with a pattern-match error if the program has any incomplete (non-exhaustive) patterns in definitions or case alternatives. This paper describes a static checker that allows non-exhaustive patterns to exist, yet ensures that a pattern-match error does not occur. It describes a constraint language that can be used to reason about pattern matches, along with ...

In recent years, there has been increased interest in using data mining techniques to extract frequent patterns from temporal sequences. Previous work mainly considers finding global patterns, where every record in the temporal sequence contributes to support the patterns. However, local patterns, which are frequent only in some time durations, are actually very common in practice and are poten...

We present a photorefractive (PR) memory setup that permits the storage of N = 64 images of 128 X 128 binary pixels in a BaTiO3 crystal by the deterministic phase-encoding technique.`-4 Because of the absence of any moving mechanical parts this multiplexing method permits a reliable and very fast random access to the images. This memory could be used in digital computing or for pattern recognit...

The miscibility-immiscibility phase transition in binary Bose-Einstein condensates (BECs) can be controlled by a coupling between the two components. Here we propose a new scheme that uses coupling-induced pattern formation to test the Kibble-Zurek mechanism (KZM) of topological-defect formation in a quantum phase transition. For a binary BEC in a ring trap we find that the number of domains fo...

We study a neural-network model including Gaussian noise, higher-order neuronal interactions, and neuromodulation. For a first-order network, there is a threshold in the noise level (phase transition) above which the network displays only disorganized behavior and critical slowing down near the noise threshold. The network can tolerate more noise if it has higher-order feedback interactions, wh...
