Electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. The critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. Switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...
در جامعه¬ی کنونی به علت مسائل و مشکلات زیست محیطی تمایل زیادی در جهت تولید خودرو¬های هیبریدی ایجاد شده است. تا کنون تلاش¬های زیادی در جهت بهبود عملکرد سیستم تولید و انتقال توان خودرو¬های هیبریدی انجام پذیرفته است. در خودرو¬های هیبریدی کنونی با استفاده از یک چرخ-دنده خورشیدی قدرت¬های موتور احتراق داخلی و دو ماشین الکتریکی با یکدیگر ترکیب و به محور چرخ¬ها انتقال پیدا می¬کند. در این شرایط موتور اح...
Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...
ÐThis paper begins with an overview of realistic fault models for dual-port memories, divided into single-port faults and faults unique for dual-port memories. The latter faults cannot be detected with the conventional single-port memory tests; they require special tests. A precise notation for all faults, such that ambiguities and misunderstandings will be prevented, has been emphasized. Next,...
The use of artificial intelligence techniques, with the increase data generation capacity and advancement computational resources, has enabled industries to develop improve products without compromising laboratory industrial resources. In this paper, a supervised machine learning (ML) based technique was used predict yield strength (YS), ultimate tensile (UTS), elongation (EL) dual phase steels...
Security First Network Bank (SFNB) (http://www.sfnb.com) went on-line in October 1995 as the world’s first on-line bank. The paper discusses how the security architecture was designed and implemented using the most currently available security technologies. The encryption technologies used to transport information across the Internet are widely known. Less widely known is how to protect the sys...
In this paper, a simple dual-band dual-polarized aperture stacked patch antenna with double sided notch is presented. This antenna is suitable for operation in telecommunication base stations. One of the bands covers the GSM band, while the other covers both DCS and UMTS bands. The proposed antenna shows good port decoupling of less than -30dB for dual linear polarization over its operating ban...
امروزه با افزایش نیاز به خودروهای سواری، میزان سوخت فسیلی استفاده شده در خودروها نیز افزایش یافته است. از طرفی با توجه به بحران های انرژی و کمبود سوخت های فسیلی در آینده و همچنین افزایش آلودگی هر چه بیشتر هوا و آسیب دیدن لایه ازون، نیاز به یک راهکار جایگزین برای خودروهای احتراقی بیش از بیش احساس می گردد. در ابتدا خودروهای برقی که در آنها از باتری قابل شارژ به عنوان منبع انرژی استفاده می گردد به...
In this paper, a co-axial dual-mechanical ports flux-switching permanent magnet (CADMP-FSPM) machine for hybrid electric vehicles (HEVs) is proposed and investigated, which is comprised of two conventional co-axial FSPM machines, namely one high-speed inner rotor machine and one low-speed outer rotor machine and a non-magnetic ring sandwiched in between. Firstly, the topology and operation prin...
