Abstract Sentiment analysis is the process of determining sentiment polarity (positivity, neutrality or negativity) text. As online markets have become more popular over past decades, retailers and merchants are asking their buyers to share opinions about products they purchased. a result, millions reviews generated daily, making it difficult make good decision whether consumer should buy produ...

Brain storm optimization (BSO) and particle swarm (PSO) are two popular nature-inspired algorithms, with BSO being the more recently developed one. It has been observed that an advantage over PSO regarding exploration a random initialization, while is capable at local exploitation if given predetermined initialization. The algorithms have also examined as hybrid. In this work, algorithm was hyb...

مادة آلی محلول رنگی (CDOM) مقیاس مهمی در سنجش کیفیت آب است. می‌توان اذعان کرد CDOM نور موجود لایه‌های را کاهش می‌دهد و فعالیت‌های بیولوژیکی فتوسنتز مختل می‌کند سرانجام، مانع رشد جمعیت فیتوپلانکتون‌‌هایی می‌شود که برای زنجیرة غذای آبزیان ضروری‌اند. بیشتر تحقیق‌هایی تا کنون به انجام رسیده، از طول موج خاصی اندازه‌گیری ضریب جذب استفاده شده است اما، این تحقیق، امکان گسترة‌ وسیعی باندهای طیف مرئی، تع...

Despite the advances mobile devices have endured, they still remain resource-restricted computing devices, so there is a need for technology that supports these devices. An emerging such resource-constrained called fog computing. End can offload task to close-by nodes improve quality of service and experience. Since computation offloading multiobjective problem, we consider many factors before ...

En la Tecnicatura de Asistencia Odontológica, desde el mes marzo en que se declaró Aislamiento Preventivo Social y Obligatorio (APSO) hasta actualidad, implementamos actividades virtuales sincrónicas asincrónicas para desarrollo los contenidos temáticos del programa. Para crear un contexto enseñanza aprendizaje, utilizamos entorno virtual plataforma institucional videoconferencias además presen...

در این مقاله، به‌منظور رفع برخی محدودیت‌های شناسایی ساختمان تصاویر چندطیفی، از دادة SAR به‌منزلة مکمل استفاده می‌شود. روش پیشنهادی، برای استفادة هم‌زمان اطلاعات مفید رادار و استراتژی مبتنی‌بر تلفیق تصاویر، با هدف ساختمان، مطرح همچنین، ازآن‌جاکه انتخاب ویژگی نقش بسزایی طبقه‌بندی عوارض دارد، اغلب روش‌های مرسوم رایج زمینه، مانند الگوریتم ژنتیک، نیازمند داده‌های آموزشی‌اند؛ اما دردسترس‌نبودن همیشگی...

In this paper, cantilever retaining wall design is studied as an important optimization task in civil engineering. The current study explores the efficiency of some recent swarm intelligence techniques: accelerated particle swarm optimization (APSO), firefly algorithm (FA), and cuckoo search (CS). These algorithms are verified using two benchmark case studies. In order to better determine the p...

Recently utilities and end users become more concerned about power quality issues because the load equipments are more sensitive to various power quality disturbances, such as harmonics and voltage fluctuation. Harmonic distortion and voltage flicker are the major causes in growing concern about electric power quality. Power quality disturbance monitoring plays an important role in the deregula...

The electric field distribution of insulator surface is nonuniform, and the maximum visible around two terminals insulator. Using a microvaristor layer one methods control that can reduce stresses to prevent an extension discharges on complete flashover caused by subsequent development arcing. This study targets effect zinc oxide (ZnO) microvaristors along contaminated clean composite insulator...
