We present a modular architecture for image understanding and active computer vision which consists of the following major components: Sensor and actor interfaces required for data–driven active vision are encapsulated to hide machine–dependent parts; image segmentation is implemented in object–oriented programming as a hierarchy of image operator classes, guaranteeing simple and uniform interf...

The aim of this talk is to draw the attention of the scientific community to an ambitious project to develop multipurpose software for graph theory. The basic idea of this computer system is to verify graph-theoretic properties for sets of graphs. A user specifies a property using a simple Formalised Graph Language. No programming skills are required. The next step is to specify a graphbase, a ...

We present a quantitative method for selecting optimum configurations of computer systems. For each configuration we specify a set of requirements reflecting user’s needs. The level of satisfaction of requirements is called the global preference score. Using this indicator and the total cost of each configuration we solve the following optimization problems: (1) select a configuration which max...

Abstract: fabricated. Modifications carried out in different parts of the old system in order to control mostof the growth parameters with more accuracy. The fabricated system was used to grow sapphiresingle crystals with almost 10 mm in diameter and 50 mm in length. The crystallinity andstructure of the grown crystals were characterized by computer aided single crystal X-raydiffraction techniq...

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...
