Web Services composition has received much interest from both the academic researchers and industry to support cross-enterprise application integration. Promising research projects and their prototypes are being developed. At the same time the web service environment is getting more dynamic as numerous web services are being published by the service providers in the Internet. To meet the users requirements regarding on-demand delivery of customized services, dynamic web service composition approaches have emerged. But still many compositional issues have to be overcome like dynamic discovery of services, compositional correctness, transactional supports etc. In this paper we discuss some of these issues and then investigate some of the representative dynamic web service composition approaches. We evaluate those approaches on the basis of the issues and present how the future research can benefit by addressing those issues of dynamic web service composition.
Several similarity measures such as Euclidean Distance, Histogram Intersection, Cosine or Quadratic Distances are usually used to calculate the images similarity rating. However, each of the distances has their own li...

The paper presents modern advanced development methods of control systems that minimizes the cost of development of applications which are widely applicable in industrial control of whole range of processes. Unlike the classical way of design and testing control algorithms which are based on expensive RT measurement cards or dSpace, this solution is based on industrial controllers WinPLC/WinPAC. This enables so called rapid-prototyping of control algorithms directly from Matlab-Simulink into target platform. It was used muItiplatform control system REX as a bridge between Matlab and the target platform. The paper describes whole design of control algorithms and control schemes, simulation of prepared schemes, uploading control schemes into target platform of WinPLC. Also possibilities of remote data transfer and data storage are mentioned. The real measurement on hydraulic industrial system proved its limits that were also explained in this paper.
