Design of reliable and robust controller for electric vehicle in urban and sub urban areas is very much challenging task due to time varying load torque requirement at the wheel of the vehicle. In this paper indirect field oriented vector control of induction motor, PI speed control with anti-windup scheme and hysteresis current control scheme have been proposed for three phase induction motor ...

Owing to overflows from combined sewer pipe systems, water quality of receiving waters, including urban rivers, has become worse year by year. Appropriate countermeasures that can mitigate the overflows, therefore, must be developed promptly. The authors have investigated a distributed simulation model of water quality and stormwater runoff in urban sewer pipe systems. First, a surface routing ...

The traditional way of controlling urban traffic is using centralised control approaches: There is a single control centre where decisions are made about the traffic control in the whole urban area. Currently, this paradigm is shifting towards more decentralised hierarchical approaches with smaller control centres serving sub-regions of the intersection network in a city. The paper reviews poss...

Field strength measu rements were conducted in the mov ing trai n in the UHF band in the urban and sub-urban regions of western India. The observed signal levels were compared wi th those predicted from methods like Hata, Wal fish and Bertoni, Uni form theory of diffract ion, Ibrahim and Parsons, Egli and Blomquist and Ladell and suitable methods were ident ified. These studies will be use ful ...

Data from the urban renewal experience in Syracuse, New York are used to examine the impact of race on patterns of intra-urban migration. The results show that, overall, the migration patterns exhibited an exponential decay in frequency with increasing distance. Both blacks and whites display this pattern, but blacks tend to cluster more closely around the point of origin. Indirect evidence is ...

With research to suggest that urban greenspace use can affect the health and wellbeing of adults, it is important to investigate this association in children. Compared with factors such as physical activity, research considering greenspace and its association with the health and wellbeing of children from urban areas is relatively rare. This study examined the health-related quality of life of ...
