The purpose of this paper is to propose models for project scheduling when there is considerable uncertainty in the activity durations, to the extent that the decision maker cannot with confidence associate probabilities with the possible scenarios. Our modeling techniques stem from robust optimization, which is a theoretical framework that enables the decision maker to produce solutions that will...
The scheduling of outbound baggage at international airports is a challenging tasks in the airport industry. The issue is to control the incoming baggage flow in order to balance the workload over the system. The resource consumption of the different activities, which have to be scheduled, are depending on the arrival process of the baggage. Because of high complexity we suggest a decomposition heuristic...
SDMA (spatial division multiple access) is a principle of radio resource sharing that relies on the division of the space dimension into separated communication channels. It can be used with common frequency division multiple access (FDMA), time division multiple access (TDMA) or code division multiple access (CDMA) techniques. Main terrestrial communication standards already implement SDMA. SDMA...
We have previously observed that the α 2 agonist BHT-920 induced paradoxical relaxations of rat arteries. The present study was designed to assess the responses to various α2-adrenergic/imidazoline receptor ligands in isolated rat peripheral resistance arteries. Segments of mesenteric or femoral arteries (internal diameter 250-300 μm) were studied in a myograph (mesenteric) or an arteriograph...
