Virtual worlds and avatar-based interactive computer games are a hype among consumers and researchers for many years now. In recent years, such games on mobile devices also became increasingly important. However, most virtual worlds require the use of proprietary clients and authoring environments and lack portability, which limits their usefulness for targeting wider audiences like e.g. in consumer...
Privacy is a major quality attribute of any software. Since personal data of users are collected, stored, processed, and transferred by the applications they use, they need to be assured that proper data protection is in place. Since privacy principles should be taken into account and incorporated into application design, this paper aims to promote privacy by design and presents a development of privacy...
A real-time system should operate correctly within deadlines. A failure in response will lead to loss of human life or a big damage to the property. The systems are sometimes considered only mission critical, with mission being very expensive. A Mission Critical System needs study real time software which is highly complex and is vital for the success of the mission. The mission capability depends...
In this paper we present the design, implementation and deployment of a runtime environment for computational models based on the Eclipse Equinox OSGi framework. The runtime was developed against the background of necessities and tasks in the field of steelmaking, but can be used in other domains also. We will discuss the requirements the platform had to fulfill as well as its architecture and selected...
Simulation systems of thermal power plants now have low using ratio just as operation simulation of generating unit. In this paper OPC technique is used to connect simulation system and distributed control system (DCS) in order to get data shared by different industry systems. In this way the connected system can be utilized for training of engineers, verification test of control strategy, and DCS...
The size of unified modeling language (UML) models used in practice is very large and ranges up to hundreds and thousands of classes. Querying of these models is used to support their quality assessment by information filtering and aggregating. For both, human cognition and automated analysis, there is a need for fast querying. In this context performance of model queries becomes an important issue...
This paper shows how model-driven software development (MDSD) can be applied in the bioinformatics field since biological data structures can be easily expressed by means of models. The existence of several heterogeneous data sources is usual in the bioinformatics context. In order to validate the information stored in these data sources, several formalisms and simulation tools have been adopted....
