Nurses spend much more time dealing with patients compared with other healthcare personnel. This group has a significant role in identification of threatening complexities of patients, removing medical errors and in keeping patients safe, on the other hand, a considerable amount of human errors is committed by nurses (1). Therefore, nurses have to face with many occupational risks compared with...

Fragmentation usually couples two separate processes, the loss of area and the decrease in the connectivity of the remaining patches. The well established pattern of species-area relationships (SPAR) clearly show that a loss of area will result with a decrease in biodiversity. However, the effect of fragmentation per se on biodiversity is less clear. In the literature, fragmentation per se has ...

The advantages of satellites in multicast and broadcast service provision has attracted a lot of interest within the satellite community and motivated a re-examination of the role of mobile satellite systems with regard to terrestrial networks. This paper reports on the approach taken by the IST project SATIN towards the definition of a suitable architecture for the delivery of multicast/broadc...

We consider a general adversarial stochastic optimization model. Our model involves the design of a system that an adversary may subsequently attempt to destroy or degrade. We introduce SPAR, which utilizes mixed-integer programming for the design decision and a Markov decision process (MDP) for the modeling of our adversarial phase. © 2005 Elsevier B.V.

The performance shaping factors (PSFs) of the standardized plant analysis risk-human reliability (SPAR-H) method are unclearly defined, which contributes to uncertainty human (HRA) in nuclear power plants (NPPs). This work proposes an expert-based modification approach for redefining PSFs based on four criteria terms less overlap, hierarchy, flexibility, and digitalization. For demonstration, p...

We present the development and application of small buoy systems for wave energy harvesting (free-floating or slackly moored), to produce about 1 KW per unit at full scale. These systems are targeted for powering distributed marine surveillance and instrumentation networks, and should be simple in concept, easily deployable, storm resilient, and low maintenance. Our work involved design, experi...
