Primary cutaneous B-cell lymphomas (CBCLs) are divided into three main types according to the WHO-EORTC classification: marginal zone B-cell lymphoma (MZL), follicle centre lymphoma (FCL), and diffuse large B-cell lymphoma, leg-type (DLBL) (1–4). A new tumour, lymph node, metastasis (TNM) staging system (Table SI (available from: other than mycosis fungoides and Sezary syndrome was recently pro...
BACKGROUND Alcohol consumption during pregnancy can result in a range of adverse pregnancy outcomes including Fetal Alcohol Spectrum Disorders (FASD). Risky drinking among Russian women constitutes a significant risk for alcohol-exposed pregnancies (AEP). Russian women report that obstetrics and gynecology (OB/GYN) physicians are the most important source of information about alcohol consumptio...
In this paper, the effect of number and fault current limiter(FCL) location has been investigated in order to have maximum reduction of short circuit current level in all buses in a real network. To do so, the faulty buses were identified in terms of short circuit current level by computing short circuits on the desired network. Then, while the fault current limit was modeled, its optimal locat...
During development, processor architectures can be tuned and configured by many different parameters. For benchmarking, automatic design space explorations (DSEs) with heuristic algorithms are a helpful approach to find the best settings for these parameters according to multiple objectives, e.g. performance, energy consumption, or real-time constraints. But if the setup is slightly changed and...
Recently the hybrid multi-port DC circuit breaker (MP-DCCB) is becoming popular in protecting HVDC grids, thanks to their reduction of power electronics devices. In this paper, an enhanced current-limiting DCCB (MP-CLCB) for multiple line protection proposed. The integrated fault current limiter (FCL) inside MP-CLCB can clear faster with slightly increased costs. To reduce energy dissipation re...
Fault currents of inverter-interfaced distributed generators (IIDGs) depend on inverter controllers. Thus, IIDGs fault are different than those synchronous-based DGs, both from the magnitude and waveshape perspectives. In event short-circuit faults, droop-based switch between a voltage source current source, which increases complexity non-linearity calculation (SCC). This paper proposes new SCC...
Remaining useful life (RUL) prediction is of great significance for prognostic and health management (PHM) as it can achieve more reliable effective maintenance strategies. With the advances in field deep learning, data-driven methods have provided promising results. Hence, this research presents a approach based on learning models predicting RUL mechanical systems effectively. Multiple separab...
این پایان نامه نوع هوشمندی از محدود کننده های جریان اتصال کوتاه (fcl) را معرفی می کند که شامل بخش رزونانسیlc موازی و یک مقاومت سری با خازن است. بر خلاف انواع محدود کننده های جریان خطایی که تا کنون معرفی شده، در این نوع هوشمند به جای تشخیص خطا به صورت ذاتی و یا با کمک سیستم های تشخیص مداری، از تحلیل سیگنال های جریان اتصال کوتاه رخ داده در شبکه توسط تبدیل موجک استفاده شده است. سپس یک شبکه عصبی مص...
The algorithms of the present generation practical differential relays are based on two methods. first method is ratio harmonic content current, and second one length time interval between zero-crossing points called gap-detection method. However, these methods suffer from installation fault current limiters (FCLs) in power system transformer (CT) saturation phenomenon. This paper deals with a ...
