An integrated optimization model is newly developed in this research to improve passenger transfer efficiency of an urban rail station by minimizing average waiting time of transfers in this station with rationalizing the arrival and departure time of trains in view of transfer passenger flows and their feeder services. Corresponding algorithm is also designed to search for the optimal solution...

Abstract This study aims to measure air bacteriological concentration, determine the effect of temperature, humidity, and wind speed on identify genus bacteria found around Gegerkalong waste transfer station. Sampling at stations was based a radius 0, 10, 30 60 meters East, West, South North station 09:00, 12:00 18:30 with 3 replicates. The method used concentration settling plate method. resul...

This paper presents the development of expert system to assist in the operation of solid waste transfer station. The knowledge based consists of a rule-based expert system for the diagnosis of site selection and problems of transfer station and subsequent identification of remedial control actions. Siting criteria are used to identifying and evaluating potential development sites. It is general...

the main goal of the present study is to identify characteristics of the inter-station horizontal magnetic responses and the vertical magnetic data, as two types of magnetotelluric transfer functions, in the modeling procedure. through consideration of model responses and two-dimensional inversion of synthetic data, sensitivity of the data components in detecting different geophysical structure...

The Engineering Test Satellite VIII (ETSVIII), scheduled for launch in 2004, has been developed to expand the advanced fundamental technologies required in future space exploitation, including mobile communications technology and high-precision satellite positioning technology [1]. This will be the first Japanese satellite to be equipped with an onboard atomic clock (the High Accuracy Clock: HA...

In this paper, a new traffic separation mechanism is proposed for IEEE 802.11e networks. Such Traffic Separation Mechanism (TSm) allows the coexistence of CSMA default stations with real-time stations in the same network domain. A station implementing the proposed TSm scheme has the same operating behavior as a default IEEE 802.11e network station, except in what concerns the evaluation of the ...

We successfully contract timetable networks with realistic transfer times. Contraction gradually removes nodes from the graph and adds shortcuts to preserve shortest paths. This reduces query times to 1ms with preprocessing times around 6 minutes on all tested instances. We achieve this by an improved contraction algorithm and by using a station graph model. Every node in our graph has a one-to...

Even though solid waste management has become a major public health and environmental concern in urban areas of Ethiopia, only 2% of the population receive solid waste management services. The primary objective of this study is to assess solid waste management practices of Bahir Dar City. The technique of multistage random sampling has been employed to draw 350 households for this study, with b...

an investigation has been carried out on the temperature of a biscuit on the cooling line of razavi food industries company. for thispurpose, the time variations of biscuit’s top surface temperature in traveling from oven to packing station on the conveyor packing station by conveyors has been studied. the fourier field equation for transient heat transfer is used as the basis for the determini...
