Information Resources Management (IRM) is the concept that information is a major corporate resource and must be managed using the same basic principles used to manage other assets. Furthermore it is a process that links business information needs to information system solutions. However there is no step-by-step guideline for implementing IRM, in this paper(More)
A new algorithm along with its hardware scheme has been proposed for consecutive generation of the symbol addresses involved in the symbol interleaving process of a digital video broadcast terrestrial (DVB-T) standard modulator. Advantages achieved through the utilization of this architecture in a DVB-T modulator design outperforms the one presented in the(More)
One of the key characteristics of the projects, especially construction projects, is executing the scope of work in a specific amount of time. As project time overrun may have bad consequences for the project performing organization such as cost overrun, damage of company’s reputation, etc. it is important to clarify between causes of excusable delays and(More)
We presented a concatenated encoder design which is used for all digital video broadcast (DVB) applications, no matter what the media of transfer is. It is composed of a scrambler, Reed-Solomon encoder, convolutional interleaver, and punctured convolutional encoder. Two novel architectures are provided for the scrambler and punctured convolutional encoder(More)
The purpose of this paper is to rank construction projects‟ success in a post delivery phase. To attain this objective, a data envelopment analysis (DEA) approach is used. The model‟s output is a project success index which is calculated based on five project success criteria. These criteria which are determined by a two-round Delphi questionnaire survey(More)
