Problem-Based Learning (PBL) method emphasizes students' own activity in learning about problems, setting up their own learning goals and actively searching for and analyzing information. In this paper, we describe and discuss our experiences on applying PBL, especially the seven steps method widely used in medical faculties, in an introductory computer(More)
Smart environments require collaboration of multi-platform sensors operated by multiple parties. Proprietary event processing solutions lack interoperation flexibility, leading to overlapping functions that can waste hardware and communication resources. Our goal is to show the applicability of standard RDF and SPARQL – including SPARQL 1.1 Update – for(More)
We describe an implementation of an introductory programming course using the seven steps method of problem-based learning (PBL). In that method students working in small groups learn programming by trying to make sense of complex real-world problems, so-called cases. We outline the organization of the course and give examples of possible cases. We then(More)
Ubiquitous domains such as smart spaces, location-aware mobile systems, or internet-of-things are characterized by large and volatile sets of heterogeneous and independently behaving entities like devices, services, and other identified objects. This study focuses on efficient implementation of an event processing system to manage interaction among these(More)
—Information is produced and maintained in a building project in a concurrent and loosely coupled manner by a set of parties representing different disciplines. The multiple partial models produced in a project are interrelated since they represent different aspects of a same building. The standard conceptual schema of buildings – Industry Foundation(More)
