Role Of Technological Revolution In Transport And Communications Development, Mohamad B. Chami
Role Of Technological Revolution In Transport And Communications Development, Mohamad B. Chami
BAU Journal - Science and Technology
The arousal of technology has changed a lot of aspects in human life and has drastically changed its path through a revolution that changed the whole world. This revolution took place in various aspects while affecting significantly the global economy and from those fields that considerably affect the life of human beings in the previous and current centuries are Information and Communication Technology (ICT) and transportation. It is these two factors that play a major role in the economy of countries and dominate the lives of societies in the world. Thus, this paper studies the impact of the technology revolution …

Steel corrosion in reinforced concrete structures can lead to severe deterioration damage under static and seismic loads. In practice, it is essential to mitigate failure risk by quantifying the extent of damage and simulating the structural response of damaged structures. However, numerical modeling of the dynamic behavior of corroded structure is challenging due to high nonlinearity of the problem and its multidisciplinary nature. In addition, corrosion damage exhibits various sources of uncertainty that impede accurate deterministic modeling of the dynamic response of RC structures. Therefore, this study presents a simplified framework, to simulate the non-linear response of corroded structures under …
Optimization Of Supermarket Checkout Counters Using Integrated Greedy Algorithm, Ramzi Fayad, Hadi Abou Chakra
Optimization Of Supermarket Checkout Counters Using Integrated Greedy Algorithm, Ramzi Fayad, Hadi Abou Chakra
BAU Journal - Science and Technology
Supermarkets worldwide are facing a service dilemma whether to increase or decrease their number of counters used at checkouts. A higher number of checkouts will undoubtedly reduce waiting time at checkout, a factor in improving customer satisfaction and service quality but this will come at a cost to the Supermarket. The work conducted in this paper will therefore focus on this tradeoff between improving the customer shopping experience versus the Supermarket Cost and profitability margins. It will do so by using an optimization algorithm that can help find the optimum number of checkouts and utilization of staff resources. The optimization …
An Improvement Of Cross Entropy Thresholding For Skin Cancer, Nancy Aref Zreika N, A. Zreika, Ali El Zaart, Abdallah Al Shakik
An Improvement Of Cross Entropy Thresholding For Skin Cancer, Nancy Aref Zreika N, A. Zreika, Ali El Zaart, Abdallah Al Shakik
BAU Journal - Science and Technology
Image processing procedures in medical diagnosis are used to improve diagnosis accuracy. An example of this is skin cancer detection using the thresholding approach. Thus, research studies involved in identification of inherited mutations predisposing family members to malignant melanoma have been performed in the Cancer Genetics field. Melanoma is one of the deadliest cancers, but could be cured when diagnosed early. A fundamental step in image processing is segmentation that includes thresholding, among others. Thresholding is based on finding the optimal thresholds value that partitions the image into multiple classes to be able to distinguish the objects from the background. …
Unsteady Rotational Motion Of A Micropolar Fluid Inside A Right Circular Cylinder Using State Space Approach, Sarah Ahmad Slayi S.A.Slayi, Emad Ashmawy
Unsteady Rotational Motion Of A Micropolar Fluid Inside A Right Circular Cylinder Using State Space Approach, Sarah Ahmad Slayi S.A.Slayi, Emad Ashmawy
BAU Journal - Science and Technology
In this work, the unsteady rotational motion of an incompressible micropolar fluid inside a right circular cylinder is investigated. The classical no-slip and no-spin boundary conditions are proposed. The problem is solved analytically using the state space approach together with Laplace transform technique. The inverse Laplace transform is carried out numerically using a numerical technique based on Fourier series expansion. Numerical results for the flow field functions are represented graphically for different values of the time and micropolarity parameters.
