Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following features: Y Precise tuning of station frequencies Y Exact digital frequency display Y Keyboard entry of desired frequency Y Virtually unlimited station memory Y Up/down scanning through the band Y Station ‘‘searc...

In this work, a DC microgrid consists of solar photovoltaic, wind power system and fuel cells as sources interlinked with the utility grid. The appropriate sizing positioning electric vehicle charging stations (EVCSs) renewable energy (RESs) are concurrently determined to curtail negative impact their placement on distribution network’s operational parameters. station location problem is presen...

With the escalating contradiction between growing demand for electric buses and limited supporting resources of cities to deploy charging infrastructure, it is a great challenge decision-makers synthetically plan location decide on expansion sequence stations. In light decisions stations having long-term impacts deployment layout city traffic networks, comprehensive framework planning locations...

This paper deals with the real-time optimal operation of active distribution networks (ADNs) hosting hybrid hydrogen-electricity refuelling stations by benefiting from renewable energy sources (RESs), conversion facilities, and storage systems. The stations, which are controlled ADN operator, supply electricity hydrogen for electric vehicles (EVs) (HVs), respectively. In addition, deployment wa...

Lastik tekerlekli toplu taşıma sisteminde çığır açan BRT sistemi, raylı sistemlere göre proje ve uygulamada daha esnek ekonomik seçenekler sunmaktadır. Bu nedenle ulaşım otoritelerinin sisteme olan rağbetinin her geçen gün artmasına, diğer yandan yolculuk sürelerinin kısa, sefer sıklığının fazla olması da yolcuların ilgisine yol açmaktadır. kadar yoğun talep gören sistemde, araç kuyruklarının o...

noise is one of the major hazardous occupational exposures and one of the occupations at risk is the transportation industry. however, few studies have measured and reported the amount of noise exposure in drivers. in this study, we evaluated noise exposure among the public transportation bus drivers of one major iranian city, kerman, southeast iran. eighty public transportation buses in the st...

Transit is one of the vital service sectors of the present and the future US economy, and it holds tremendous social significance as an estimated 25% US citizens rely on some form of a transit system. Owing to their inherent flexibility and low capital costs, bus transit system are most attractive to meeting the growing transportation requirements. Despite their vital importance, conventional b...

The theory of logistic transportation systems deals with models of phenomena connected with movement of goods and persons. The developed model of the transportation system is expected to simulate a real system, but also should help us to solve given transportation tasks. In order to describe transportation system (rail, bus or air), as a routine a connection graphwould be used. Vertices of the ...

The Last Mile Problem (LMP) refers to the provision of travel service from the nearest public transportation node to a home or office. We study the supply side of this problem in a stochastic setting, with batch demands resulting from the arrival of groups of passengers who request last-mile service at urban rail stations or bus stops. Closedform approximations are derived for the performance o...

The Distributed Queue Dual Bus protocol, the media access protocol of the current I E E E 802.6 standard for Metropolitan Area Networks, has two major drawbacks. First, it is not able t o utilize the full bandwidth. Also, it needs considerable t ime until a f a i r distribution o f bandwidth t o the stations is achieved. I n this study a protocol for dual bus networks is proposed which does not...
