یافتن رابطه بین وضعیت و تحول پوشن سپهر و شرایط جوّی در سطح زمین، علاوه بر اینکه درک ما را از چگونگی عملکرد لایه های گوناگون جوّ و دینامیک آنها افزایش می دهد، پیامدهایی برای بهبود پیش بینی وضع هوا و اقلیم در هر منطقه دربر دارد. هدف اصلی پژوهش حاضر، شناخت این پیامدها با تمرکز بر منطقه جنوب غرب آسیا است. در این پژوهش، داده های روزانه بازتحلیل ncep/ncar شامل فشار، دما، دمای کمینه، رطوبت نسبی، آهنگ با...
This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular Extended Difference Family Quasi-Cyclic Low-Density Parity-Check codes. The key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. Cryptanalytic methods show that the improved cryptosystem has a significant security advantage over Ra...
The conversion method from Non-Audible Murmur (NAM) to ordinary speech based on the statistical voice conversion (NAM-toSpeech) has been proposed towards realization of “silent speech telephone.” Although NAM-to-Speech converts NAM to intelligible voices with similar quality to speech, there is still a large problem, i.e., difficulties of the F0 estimation from unvoiced speech. In order to avoi...
The finding that liver necrosis caused by the environmental glutathione (GSH)-depleting chemical, bromobenzene (BB) is associated with marked impairment in O- and S-methylation of BB metabolites in Syrian hamsters raises questions concerning the role of methyl deficiency in BB toxicity. N-Acetylmethionine (NAM) has proven to be an effective antidote against BB toxicity when given after liver GS...
Non-audible murmur (NAM) is an unvoiced speech received through body tissue using special acoustic sensors (i.e., NAM microphones) attached behind the talkers ear. Although NAM has different frequency characteristics compared to normal speech, it is possible to perform automatic speech recognition (ASR) using conventional methods. In using a NAM microphone, body transmission and the loss of lip...
The role in longevity and healthspan of nicotinamide (NAM), the physiological precursor of NAD+, is elusive. Here, we report that chronic NAM supplementation improves healthspan measures in mice without extending lifespan. Untargeted metabolite profiling of the liver and metabolic flux analysis of liver-derived cells revealed NAM-mediated improvement in glucose homeostasis in mice on a high-fat...
Non-Audible Murmur (NAM) is an unvoiced speech signal that can be received through the body tissue with the use of special acoustic sensors (i.e., NAM microphones) attached behind the talker’s ear. In a NAM microphone, body transmission and loss of lip radiation act as a low-pass filter. Consequently, higher frequency components are attenuated in a NAM signal. Owing to such factors as spectral ...
In order to realize a new human communication style using Non-Audible Murmur (NAM) that cannot be heard by people around a speaker, we perform conversion from NAM to ordinary speech (NAM-to-Speech). NAM-to-Speech has a possibility of realizing “non-speech telephone” that is a technique for communicating each other by talking in NAM and hearing in speech. In this paper, we apply a statistical co...
.در این مطالعه برای یک دوره 10 ساله (1388-1378)، بارش با استفاده از داده های تاریخی بارش در زیرحوزه های اسکندری و قلعه شاهرخ واقع در بالادست حوزه آبخیز سد زاینده رود با استفاده از سیستم استنتاج فازی-عصبی (anfis) و شبکه های عصبی مصنوعی (anns) پیش بینی شده است. همچنین بهترین ترکیب ورودی به منظور پیش بینی بارش، با استفاده از الگوریتم ژنتیک مشخص شده است.سپس دبی رواناب تولید شده ناشی از بارش پیش بین...
The cellular mechanisms whereby excess maternal nutrition during pregnancy increases adiposity of the offspring are not well understood. However, nicotinamide (NAM), a fundamental micronutrient that is important in energy metabolism, has been shown to regulate adipogenesis through inhibition of SIRT1. Here we tested three novel hypotheses: 1) NAM increases the adipogenic response of human umbil...
