Innovation In Egyptian Linear Construction Projects: Enablers, Obstacles, And Suggested Improvements, Saeed Ahmed Elshinawy, Mohammed Elsayed Elsharkawy Assis. Prof., Adel Ibrahim Eldosouky Emeritus Professor

Journal of Engineering Research

Abstract- This research aims to investigate the obstacles, enablers, and suggested improvements for innovation in the Egyptian linear construction projects. The study is motivated by the need to understand the dynamics of innovation within these projects and identify practical approaches to overcome obstacles to innovation.

Owners, contractors, and consultants involved in linear construction projects constituted the target population of the study. A structured questionnaire was used to collect data from a representative sample of 70 participants.

It is found that time and budget constraints, along with traditional tendering and procurement methods were significant obstacles to innovation, while technological and technical …

Real Records Scaling Factors Optimization To Fit The Syrian Design Spectra Using Genetic Algorithm, Seraj Jdyd

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

After selecting real seismic records it is necessary to scale these records to match the intensity of the earthquake expected for the site. Generally, scaling can be made by ground motions uniform scaling in time domain which is simply scaled up or down the ground motions uniformly to best match (in average) the target spectrum within a period range of interest. It’s an engineer’s job to find the best scaling factors to best match the target spectrum, which is a complex task, so we employed the Genetic Algorithm (GA) in finding those scaling factors to achieve the best results.
