The indiGo project offers a solution for tackling resistance against and problems while executing process models: eParticipative Process Learning. Via moderated, web-based discussions, consensus about a process is created and process models are reviewed to achieve better understandability or other quality aspects. Furthermore, problems during the execution of a process are solved collaborativel...

Aspect Oriented Programming (AOP) was introduced 10 years ago and many research projects have focused on broadening AOP and its target areas. However, few applications in the Grid computing world adopt AOP in comparison with very vigorous research of AOP. Therefore, we present a case study that covers a general networking problem in the Grid computing. AOP provides a novel solution of the probl...

Recent research into distortion-oriented displays (DODs) and non-linear magnification techniques has considered extending their application to large three-dimensional datasets. Inherent properties of three-dimensional datasets introduce some difficulties that do not occur in 2 0 environments. This paper considers the Occlusion Problem that of context data hiding, or occluding, some or all of th...

Important features of networks, e.g., length of shortest paths, centrality, are defined in a graph theoretical way. Bipartite graphs are frequently applied, not only in computer science (e.g. PetriNets), but in other sciences as well. They are used to represent various problems, for example, in medicine or in economy. The relations between customers and products can be represented by bipartite ...

In this paper, we present a programming paradigm for AI problem solving based on computational concepts drawn from Affective Computing. It is believed that emotions participate in human adaptability and reactivity, in behaviour selection and in complex and dynamic environments. We propose to define a mechanism inspired from this observation for general AI problem solving. To this purpose, we sy...

Nowadays spatial data is becoming as a key element for effective planning and decision making in all aspects of societies. Spatial data are those data which are related to the features on the ground. In this way, a Geographic Information System (GIS) is a system that captures, analyzes, and manages any spatially referenced data. This paper analyzes the architecture and main features of Geograph...

The paper describes a software package called LaGO for solving nonconvex mixed integer nonlinear programs (MINLPs). The main component of LaGO is a convex relaxation which is used for generating solution candidates and computing lower bounds of the optimal value. The relaxation is generated by reformulating the given MINLP as a block-separable problem, and replacing nonconvex functions by conve...

Background: Hospital as the gravitational center of the health and treatment system and an open system involving complex processes and various (qualitative and quantitative) resources, needs an effective leadership style and an approperiate strategy to solve the organizational disagreements and conflicts in order to achieve its basic objectives. The object of this research is to study the relat...
