The stability of a fishery system was investigated using two forms of a stochastic computer simulation model that was individually based in terms of the fishing boats. Fish catch was partitioned among boats according to two catch processes: an unranked process in which all boats had equal ability to catch fish and a ranked catch model in which a boat’s ability to catch fish depended on its weal...

Excessive vibration of turbomachinery blades causes high cycle fatigue (HCF) problems requiring damping treatments to mitigate vibration levels. Based on the technical challenges and requirements learned from previous turbomachinery blade research, a feasibility study of resonant damping control using shunted piezoelectric patches with passive and active control techniques has been conducted on...

Introduction / objectives The frequent use of peripheral venous catheters (PVC) generate a significant number of infections. Since 2005, a standard recommendation edited by the French Society for Hospital Hygiene has been promoted in healthcare facilities (HCF). In 2009, the French Group for Evaluation of Practices concerning Hospital Hygiene (GREPHH) has provided an evaluation tool for PVC pra...

The multimedia applications require the network to provide a trustworthy service suitable to meet their Quality of Service and real-time requirements, managing efficiently the available resources. In this paper we present a performing solution for the multimedia support over IEEE 802.11e networks that aims to combine both its Medium Access Control functions, Enhanced Distributed Channel Access ...

Designing algorithms capable of efficiently constructing minimal models of CNFs is an important task in AI. This paper provides new results along this research line and presents new algorithms for performing minimal model finding and checking over positive propositional CNFs and model minimization over propositional CNFs. An algorithmic schema, called the Generalized Elimination Algorithm (GEA)...

The upcoming new standard IEEE 802.11e aims at providing Quality of Service (QoS) support in 802.11 Wireless LANs. While the QoS mechanisms in 802.11e, namely the EDCF and the HCF, have already been defined in the standard draft, the challenge lies in the configuration of these mechanisms in order to provide the desired services. In this paper, we deal with the configuration of the EDCF in orde...

Questions about the overcrowded situation of fresh­ man were hurled at Fr. James Riehle, director of Student Housing, last night at an informal rap session in Sorin Hall. He opened the floor immediately for questions, and the barrage did not halt until two hours later. In response to the present housing situation he stated that as of September 12 there were 28 beds available and a problem of so...

Modern wireless networks are offering a wide range of applications that require the efficient integration of multimedia and traditional data traffic along with QoS provision. The IEEE 802.11e workgroup has standardized a new QoS enhanced access scheme for wireless LANs, namely Hybrid Control Function (HCF). HCF consists of the Enhanced Distributed Channel Access (EDCA) and the Hybrid Control Ch...
