This paper proposes an Adaptive Neural Fuzzy Inference System (ANFIS) model for diagnosis of combined Inter Turn Short Circuit (ITSC) and Broken Rotor Bar (BRB) faults in a Squirrel Cage Induction Motor (SC-IM). The signal the stator current is obtained from really healthy faulty SC-IM. Experimental tests have been set up using 1.5 Hp/380 V three-phase SC-IM with different ITSC BRB under loadin...

Diabetic retinopathy (DR) is a retinal disease representing one of the main causes vision loss in developed countries. In early stage DR, disruption blood barrier (BRB) observed, and it will lead to vascular permeability visual impairment. Therefore, protection against breakdown BRB may be useful strategy for prevention DR. Matrix metalloproteinases (MMPs) plays an important role degradation ex...

Learning emotion assessment is a non-negligible step in analyzing learners’ cognitive processing. Data are the basis of learning assessment. However, existing models cannot balance model accuracy and interpretability well due to influence uncertainty process data collection parameter errors. Given above problems, new based on evidence reasoning belief rule base (E-BRB) proposed this paper. Firs...

The Behavior of conventional braced frames, are not the same in tension and compression. This problem can be improved by prevention of buckling under compressive loads, which is called buckling restrained brace(BRB). In this field TTD metal damper also have much attention due to simplicity in construction and execution. This damper is recommended because of accessing to better performance than ...

Depending on the tectonic activities, most buildings subject to multiple earthquakes, while a single design earthquake is suggested in most seismic design codes. Perhaps, the lack of easy assessment to second shock information and sometimes use of inappropriate methods in estimating these features cause successive earthquakes mainly were ignored in the analysis procedure. In order to overcome t...

در طراحی سازه¬ها تحت بارهای جانبی، جذب انرژی توسط سیستم¬های جاذب انرژی از مهمترین بحث¬های مطرح می¬باشد. از جمله سیستم¬های باربر جانبی، مهاربندها می¬باشند. مهاربندهای مقید در برابر کمانش brb)) و مهاربندهای از جنس آلیاژهای حافظه¬دار شکلی (sma)، سیستم¬های جدید در این زمینه می¬باشند. در این تحقیق به مقایسه¬ی دو سیستم مهاربندی پرداخته شده است. سیستم باربر جانبی در این تحقیق قاب خمشی همراه با مهاربند...

قاب های دارای مهاربند مقاوم در برابر کمانش (brbf) از جمله سیستم های مقاوم در برابر بارهای جانبی می باشند که در سال های اخیر مورد توجه مهندسان قرار گرفته است. brb شامل هسته فولادی است که با مکانیسمی از کمانش فشاری آن جلوگیری شده است. این مهاربند ها به دلیل عدم کمانش، ظرفیت تقریبا یکسان در فشار و کشش و ظرفیت بالای استهلاک انرژی، رفتار مناسبی در برابر زلزله از خود نشان می دهند. البته این مهاربندها...

The purpose of the present study was to characterize rat organic anion transporter (Oat) 3 (Oat3, Slc22a8) in the efflux transport at the inner blood-retinal barrier (BRB). Reverse transcription-polymerase chain reaction analysis showed that rat (r) Oat3 mRNA is expressed in retinal vascular endothelial cells (RVECs), but not rOat1 and rOat2 mRNA. The expression of Oat3 in the retina and human ...

PURPOSE Stem cell factor (SCF) has been recently acknowledged as a novel endothelial permeability factor. However, the mechanisms by which SCF-induced activation of the SCF cognate receptor, cKit, enhances endothelial permeability have not been fully elucidated. This study aimed to investigate the role of Src in SCF-induced breakdown of the blood-retinal barrier (BRB). METHODS In vitro endoth...
