This paper describes software architecture of using GPRS technique to provide wireless data communication for a traffic data collection system. The development of the communication software was based on two scenarios: Centralized Database Management (CDM) and Distributed Data Management (DDM) systems. They were used effectively to improve the current “download on demand” and post event analysis working mode. A “close to the real time” data transmission was achieved. As the essential requirement of an Intelligent Traffic System (ITS), the application of the GPRS technique enabled the user to access the real time traffic data uploaded from multiple road side traffic data collection units. In this study, the authors have successfully developed and tested the communication software of a proposed CDM system and the software architecture of the DDM system was also discussed. For the DDM system, the interface and communication software were designed using Unified Modeling Language and developed as an Object-oriented system based on the .NET platform. The database part was developed using Microsoft SQL. The reliability and the performance of the DDM system were evaluated against proposed hardware configurations.

This paper presents investigations into the implementation of input shaping schemes for anti-sway control of a gantry crane system. A lab-scale gantry crane is considered in the experimental work. An unshaped bang-bang input voltage is used to determine the characteristic parameters of the system for design and evaluation of the input shaping schemes. The input shaping schemes with different derivatives were designed based on the properties of the system. Implementation results of the response of the gantry crane with the input shaping schemes are presented in time and frequency domains. The performances of the input shaping are examined in terms of level of swing angle reduction, and time response specifications. Finally a comparative assessment of the input shaping schemes with different derivatives is discussed and presented.

Supercontinuum is said to have generated when several nonlinear effects like self – phase modulation, cross –phase modulation, four – wave mixing, stimulated Raman scattering etc. lead to extreme spectral broadening of ultrashort optical pulses. In this paper, we have numerically demonstrated the effect of variation in the wavelength of optical pulses on the supercontinuum generation in SC – 5.0 – 1040TM, a highly nonlinear PCF.

A lot of semantic information is lost due to keyword centric approach of information indexing. Web search should be based on ‘context’ of the query and not only on the keywords in query. It is only possible when a context from a query as well as document is sensed and which requires a context based indexing approach. A model for contextual indexing has been proposed which will try to find direct and indirect associations between keywords/concepts in a document and their related contexts with respect to query, thereby helping web searching become more relevant and precise.

Shim6 is a host-centric multihoming solution for IPv6 networks which has been chosen by the IETF as a multihoming solution for the future Internet. Shim6 employs REAchability Protocol (REAP) for failure detection and recovery. REAP enables multi-addressed hosts which are involved in a communication to detect and recover path failures without breaking the transport layer sessions. One concern about deploying shim6 is the performance of REAP in large networks like campus or enterprise networks. We modeled and simulated this protocol by using stochastic activity networks (SAN) and performed an analysis of its performance. This paper presents the results of the simulation. We also investigated the effect of send timer and initial probes on the performance.

one of the differences of freight modeling to passenger modeling is its complex pattern in supply chain process. Probability of tour is a function of network and impedances among destinations and fleet constraints. It is obvious that in network with passage restrictions (in residential streets and collectors) for heavy vehicles, the number of destinations in each tour (tour length) will increase and instead it may increase the cost of the users. This paper discusses about activities of major agents, in freight movement, in our case study which is the second major city in Iran. Cost of shippers and number of destinations in tour, will be compared in two states. The first state is no restriction and the second state is passage restriction in some residential streets.

The objective of this research is to propose a new data conjugate sub carrier mapping technique that combines ICI self cancellation method using data allocation in space-time-frequency block codes (STFBC) MIMO-OFDM system. It aims to achieve maximum diversity order and to compensate integrated effect of FO for ICI reduction in the system. Using theoretical derivation of the Common Phase Error (CPE), ICI and Carrier to Interference Ratio (CIR), a simulation model is then being used to compare with data conjugate adjacent method. The results show that the ICI contained in the received signals can be effectively reduced using the propose data conjugate method. Thus, the proposed method outperforms the adjacent method by approximately reducing the ICI at high signal to noise ratio (SNR) and CIR.
