background : one of the best ways to control the malaria disease and to be protected human against anopheles mosquito biting is the use of repellents. throughout repellents, herbal ones may be an appropriate and safe source for protection. methods : chemical constituents of achillea vermiculata and satoreja hortensis were determined by using gas chromatography-mass spectrometry. efficacy and t...
Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI) plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote bac...
In IP-based media delivery services, we often deal with predictable network load and traffic, making it beneficial to use advance reservations even when network failure occurs. In such a network, to offer reliable reservations, fault-tolerance related features should be incorporated in the advance reservation system. In this paper, we propose an optimized protection mechanism in which backup pa...
This paper deals with an optimal linear insurance demand model, where the protection buyer can also exert a time-dynamic costly prevention effort to reduce her risk exposure. is expressed as stochastic control problem that consists in maximising exponential utility of terminal wealth. We assume reduces intensity jump arrival process and interpret this dynamic self-protection. solve by using pro...
