در این پایان نامه سعی شده است به منظور کشف فعال بودن فرستنده ی مبتنی بر مخابرات ofdm در کانال، یک آشکارساز کارآ با داشتن مشخصه های مورد نیاز رادیوشناختی طراحی گردد. از جمله این مشخصه ها زمان حقیقی بودن عملیات و بنابر این پیچیدگی محاسباتی کم آشکارسازهاست. با توجه به ویژگی های مخابرات ofdm، کانال مخابراتی مورد استفاده و نیازمندی های رادیوشناختی اقدام به طراحی آشکارساز umpi می کنیم که به دلیل وابس...
The unbalanced magnetic pull (UMP) is one of the main vibration sources motorized spindle. A calculation model UMP in a synchronous spindle considering magneto-thermal coupling proposed this paper. finite element analysis models electromagnetic field and temperature are first established. Then two-way method effect variations on material properties motor proposed. An experiment conducted to ver...
This paper evaluates the literature on international unconventional monetary policies (UMPs). Introducing market segmentation, limits-to-arbitrage, and time-consistent policy in standard models permits a theoretical role for UMP. Empirical studies provide compelling evidence that UMPs influenced asset prices tail risk desired manner. Calibrated modeling vector autoregressive (VAR) exercises imp...

BACKGROUND AND AIMS The distinction between benign and malignant gastrointestinal stromal tumours (GISTs) is often unclear at the clinical and histopathology levels. GISTs are believed to arise from the stem cells of Cajal. In order to define genetic biomarkers and identify target genes related to GIST progression, we analysed and compared benign and malignant GISTs with verified follow up data...
A lexicostatistical classification is proposed for 20 languages and dialects of the Lezgian group of the North Caucasian family, based on meticulously compiled 110-item wordlists, published as part of the Global Lexicostatistical Database project. The lexical data have been subsequently analyzed with the aid of the principal phylogenetic methods, both distance-based and character-based: Starlin...
BACKGROUND AND AIM The pathological diagnosis of papillary thyroid carcinoma (PTC) is usually easily achieved. However distinguishing the follicular variant of papillary carcinoma (FVPC) from other follicular thyroid lesions is an area of controversy. In this study we investigated the role of CD56 and claudin-1 in discriminating the FVPCs from other solitary follicular patterned nodules. We als...
New high resolution, very high signal-to-noise spectra of ultra-metal-poor (UMP) giant stars HD 115444 and HD 122563 have been gathered with the High-Resolution Echelle Spectrometer of the McDonald Observatory 2.7m Telescope. With these spectra, line identification and model atmosphere analyses have been conducted, emphasizing the neutron-capture elements. Twenty elements with Z > 30 have been ...
