در چند سال اخیر نیاز به استفاده از منابع انرژی تجدیدپذیر نظیر انرژی خورشیدی، پیل های سوختی و انرژی بادی افزایش یافته است. از این میان پیل های سوختی به دلیل عدم آلودگی، بازدهی بالا و مستقل بودن از شرایط آب و هوایی، منابع انرژی بسیار مفیدی هستند. روش مرسوم برای کنترل این پیل ها استفاده از یک مبدلdc/dc می باشد.در کاربردهای سه فاز مانند درایو موتورهای ac، یک اینورتر هم باید در مسیر مبدل dc/dc قرار ...
In this paper we argue that researchers in Intelligent Data Analysis (IDA) in Medicine and Pharmacology should consider textual databases as an additional source of knowledge. We describe three areas where medical knowledge extraction from textual databases can be fruitful: finding new applications for existing drugs, evolution of medical knowledge in time, and drug risk assessment. We evaluate...

introduction more and better production of food is one of the necessities of today's world. since production of agricultural products of one region depends on the air and climatic factors, it is important to examine the role of climate in agriculture (mohammadi et al., 2004: 123). in relation to agroclimatology, numerous studies by different scientists and agricultural climatologists have ...
This paper presents an image blending approach which combines optimal seam finding and transition smoothing for merging a set of aligned source images into a composite panoramic image seamlessly. In this approach, graph cut optimization is used for finding optimal seams in overlapping areas of the source images to create a composite image. If the seams in the composite image are still visible, ...
The studied area located in south and south western Arak town and are the part of Sanadaj-Sirjan Zone. The plutonic rocks in Astaneh and Boroujerd areas are quartz diorite, granodiorite and monzogranite. In addition to plutonic rocks, subvolcanic rocks of rhyodacite composition are present in Astaneh area. In general, in these areass mineral assemblage is the same in different units. The common...
