This paper presents a hybrid metaheuristic algorithm (HMA) for Multi-Mode Resource-Constrained Project Scheduling Problem (MRCPSP) in PERT networks. A PERT-type project, where activities require resources of various types with random duration, is considered. Each activity can be accomplished in one of several execution modes and each execution mode represents an alternative combination of resou...

Sustainable development is a development that meets the needs of present generation while not compromising the ability of future generations to also meet their needs. There are 2 cases of sustainability. Case-1 is due to the discrepancy of environment and Case-2 is due to the change of environment. User, usage context and cultural aspects play important roles in the sustainability of system. Di...

In this paper we discuss the Wireless Mesh Network developed in the scope of the IBBT Wireless Building Automation project. This WMN is designed as a high datarate wireless backbone interconnection between the other wireless networks used in the WBA architecture. We will demonstrate that switched Ethernet is a technology that, with minimal effort, can be used as a base for WMNs. We will also ta...

We present the results of a study that focuses in on issues of validity of the motivation towards the environment scale (MTES) in the context of Flanders (the Flemish-speaking community in Belgium). The instrument was developed almost two decades ago in Canada, and is designed to measure the self-determined motivation of people for performing pro-environmental behaviors, but has not yet been ap...
