the issue of transmission of hadith, in western views, is an influential factor concerning the historical reliability of hadith. many western scholars dealing with muslim tradition assumed that in the main the hadith had been transmitted orally and consequently through the oral transmission process, it has been distorted and changed. the reason for this idea is the existence of some prophetic h...
noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. a common problem in imaging systems by using cmos or ccd sensors is appearance of the salt and pepper noise. this paper presents cellular automata (ca) framework for noise removal of distorted image by the salt an...
Abstract A modification of transmit filtering in single-carrier (SC) transmission yields an improvement of system performance in aspects of either peak-to-average power ratio (PAPR) or error probability. In this paper, such a novel transmit filtering is introduced in order to reduce PAPR, while maintaining the error probability similar to conventional transmit filter. The filter is determined b...
فرسایش خاک یکی از مهمترین مسایل اقتصادی، اجتماعی و زیست محیطی جهان است. طبق اطلاعات موجود، آسیا بیش از سایر قاره ها مشکل فرسایش دارد و در این میان ایران دارای میزان فرسایش خاک بالاییاست. مدیریت حوزه های آبخیز در کاهش فرسایش مهم می باشد. در کشور ما اکثر حوزه های آبخیز، به ویژه حوزه های آبخیز کوهستانی، فاقد ایستگاه های اندازه گیری به تعداد کافی می باشند و گاه ایستگاه های ناقص برای مدت طولانی فاقد...
the iranian poultry sector has experienced many significant structural changes in recent years. such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. this paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of ardebil (ar), east azerbaijan (ea) and west azerbaijan (wa) ...
Frequent simulation and irritation of NMDA receptors by glutamate mediators can lead to burning pain, allodynia and hyperalgesia, even after stopping the irritant factor. Opioid-induced hyperalgesia and peripheral nerve injuries in lower extremities orthopedic surgeries can also make the same symptoms, which sometimes make it difficult to diagnose it from causalgia (type II complex regional...
In areas of seasonal malaria transmission, the incidence rate of malaria infection is presumed to be near zero at the end of the dry season. Asymptomatic individuals may constitute a major parasite reservoir during this time. We conducted a longitudinal analysis of the spatio-temporal distribution of clinical malaria and asymptomatic parasitemia over time in a Malian town to highlight these mal...
A hybrid data transmission technique for multimedia satellite broadcasting is proposed. The main-channel data and sub-channel data are simultaneously transmitted using QPSK modulation and 2ASK modulation, respectively, but the latter modulation timing is offset by half the main-channel QPSK symbol length in time. The BER performance in a Gaussian channel, the transmission bandwidth, and the tra...
