Semantically-enriched Service-Oriented Business Applications

Process planning and control has a key role at building a proper manufacturing both in theoretical and practical manner. Quality and effectiveness of completing end-user requirements depend on process control and quality assurance which is mostly supported by computer aided systems. However complex software solutions supporting manufacturing, process control and quality assurance are often placed separated at different participants of the supply-manufacturing-distribution process. Software solutions and systems used by the participants can be different in many ways like the platform they are built on. Re-integration of the whole process (processes might be partitioned into supply, production, distribution, etc. parts corresponding due to the specialization of the participants) indicates the need for integration of these separated systems. Therefore an integration solution must be conceptualized and used for ensuring proper co-working via well defined communication between these systems.

Integrated enterprise resource planning systems

The last 20 years have seen a lot of changes in the life of organizations. The always strong competition to be on the edge increased due to the saturation of the consumer markets. The new way to improve everyday working is computer-based information systems, which have become essential for survival in the last couple of years. This paper presents the short history of ERP systems first. From computer support in separated areas, through understanding the importance of big information (data) storages to proving the unique advantages of integration we arrive to the most modern ERPs. The demands (new challenges) and capabilities are examined and compared. On the other hand the creation of some practical examples and solutions are also presented. The full life-cycle (planning, development, testing, installation and continuous expansion) of the printed circuit board support system at the Department of Electronic Technology of Budapest University of Technology and Economics (BUTE) is shortly described. Lastly a modern concept and a new model are presented based on the view of business and workflow processes

Electrochemical migration of Ag in Na2SO4 environment

The effect of sulphate ion concentration on electrochemical migration (ECM) of silver was investigated by applying an in-situ optical and electrical inspection system. It was found that dendrites grow not only in an electrolyte solution with low sulphate ion concentration but also in electrolytes with medium and high or even saturated sulphate ion concentrations. According to the Mean-Time-To-Failure (MTTF) values, the migration susceptibility was decreased with the increase of sulphate ion concentration in case of low and medium concentration levels. However, the ECM susceptibility was increased at saturated concentration level.

Automatic transformation generation in service oriented architecture

Enterprise application integration (EAI) is one of the most current topics in information technology today. Applying Service Oriented Architecture (SOA) is a fair headway in EAI, but involving the productive enterprise systems (ES) into such integration scenarios still raises a lot of open issues: the data representation probably differs in participating ESs, which indicates the need for detection of semantically related concepts between them, the appropriate services of the SOA architecture must be found to the right place of the chain of the collaborative business process and the composed process containing semantic services must be prepared for the process run-time, etc. In this paper we present an approach which extends SOA standards by attaching semantic metainformation to the services of ESs. The main part of our work is the adaptation of the services from legacy systems into our semantically enriched SOA environment. The focus is set on automatic finding of semantic related pairs between global schema concepts and the concepts of services. Furthermore a method for generation of transformation rules between the services data schema and our semantic global schema is also introduced.
