Abstract— In our present work, we propose a nature inspired population based speech enhancement technique to find the dynamic threshold value using Teaching-Learning Based Optimization (TLBO) algorithm by using shift invariant property of dual tree complex wavelet transform (DT-CWT). The performance of these proposed methods are evaluated in terms of Perceptual Evaluation of Speech Quality (PES...

This paper provides a framework for optimization of Induction Hardening parameters by using Intelligent Techniques. Heat Treatment of Iron Alloy is carried out for improving Mechanical and Metallurgical properties like Ductility, Toughness, Hardness, and Tensile Strength etc. These properties play a important role for selection of material in Manufacturing Field. Induction Hardening on iron all...

In this study, we proposed a discrete teaching-learning-based optimisation (DTLBO) for solving the flowshop rescheduling problem. Five types of disruption events, namely machine breakdown, new job arrival, cancellation of jobs, job processing variation and job release variation, are considered simultaneously. The proposed algorithm aims to minimise two objectives, i.e., the maximal completion t...

The early detection of the transformer faults with high accuracy rates guarantees continuous operation power system networks. Dissolved gas analysis (DGA) is a technique that used to detect or diagnose based on dissolved gases due electrical and thermal stresses influencing insulating oil. Many attempts are accomplished discover an appropriate correctly fault types, such as Duval Triangle metho...

Abstract Different with the plain flexible job-shop scheduling problem (FJSP), FJSP routing flexibility is more complex and it can be deemed as integrated process planning (job shop) (IPPS) problem, where job shop two important functions are considered a whole optimized simultaneously to utilize in manufacturing system. Although, many novel meta-heuristics have been introduced address this corr...

بخش اورژانس یکی از شلوغ‌ترین بخش‌های یک بیمارستان است و بهبود عملکرد این تأثیر بسیاری در کیفیت ارائه خدمات دارد. اخیراً پژوهشگران به­‌دلیل تمرکز مهندسی تاب‌آوری مدیریت ناب بر کارایی سیستم‌ها توجه بسیار زیادی به دو دیدگاه کنار یکدیگر داشته‌اند. هدف پژوهش، رویکردی یکپارچه برای ارزیابی مبتنی شاخص‌های با ارتقای رضایت شغلی کاهش هزینه‌های درمانی واحد خصوصی است. منظور، ابتدا شناسایی مؤثر، مدل مفهومی مس...
