The cable equation is one the most fundamental mathematical models in the neuroscience, which describes the electro-diffusion of ions in denderits. New findings indicate that the standard cable equation is inadequate for describing the process of electro-diffusion of ions. So, recently, the cable model has been modified based on the theory of fractional calculus. In this paper, the two dimensio...
گسترش شهرها و صنایع در سال های اخیر باعث افزایش مشترکان انرژی الکتریکی از یک سو و از سوی دیگر رشد چشمگیر بارهای صنعتی و غیر صنعتی گردیده است. این مسئله مهم در کنار مسائل فراوانی همچون جلوگیری از تخریب محیط زیست، زیبایی محیط پیرامون و افزایش قیمت زمین خصوصا در شهرها، منجر به استفاده از تکنولوژی های جدیدی در جهت انتقال توان الکتریکی گردیده است. یکی از مهمترین گزینه های موجود جهت رفع این مشکلات، ا...
Cable winding is an alternative technology to create stator windings in large electrical machines. Today such cable winding is performed manually, which is very repetitive, time-consuming and therefore also expensive. This paper presents the design, function and control system of a developed cable feeder tool for robotized stator cable winding. The presented tool was able to catch a cable insid...
Introduction. To achieve a functional atraumatic cochlear implantation, intracochlear pressure changes during the procedure should be minimized. Postinsertional cable movements are assumed to induce intracochlear pressure changes. The aim of this study was to observe intracochlear pressure changes due to postinsertional cable movements. Materials and Methods. Intracochlear pressure changes were...
In the mining process of an underground coal mine, dynamic load often causes great damage to roadway and affects normal mine. this paper, deformation surrounding rocks under static different disturbance intensities is studied by numerical simulation. The results show that same condition, greater strength is, more obvious roof displacement subsidence is. With increase in propagation distance, am...
This paper proposes a SUGPDS model based on Detection and Isolation algorithm smart sensors, namely micro phasor measurement unit, sensing switching device, data concentrator, ZigBee technology, etc. for the identification, classification, isolation of various fault occurs in underground power cable distribution system. The proposed is quick tool supervising, managing, controlling faults issues...
