This paper proposes a methodology for practical siting and sizing of Hybrid energy systems (HESs) consist of: wind turbine (WT), photovoltaic (PV) and combined heat and power (CHP) units. In this method, the interaction of Plug-in Electric Vehicles (PIEVs) in the electric distribution system is considered. Electric Vehicle are seen to have some negative impacts on electric distribution system p...

This paper describes a distributed security infrastructure for mobile agents. The first property of the infrastructure is believability; this means that mechanisms are provided for authenticating information furnished by an agent. A second security property is survivability. This means that an agent computation can be programmed to survive attacks by malicious hosts on individual agents; this i...

در سال های اخیر، کاربرد مدل های هیدرولوژیکی توزیعی بر پایه فیزیکی افزایش یافته است. با این حال بسیاری از سوالات در خصوص واسنجی و صحت سنجی صحیح مدل های توزیعی و ارزیابی عدم قطعیت پارامترهای تخمینی، هنوز هم ناشناخته است. به خصوص برای مدل های پیچیده، تخمین پارامترها به طور صحیح، کاهش فضای پارامتری و استفاده از الگوریتم های موثر و کارآمد به منظور کاهش عدم قطعیت و تسهیل فرآیند واسنجی امری ضروریست. ه...
