According to its significance, robotics is always an area of interest for research and further development. While robots have varying types, design and sizes, the six degrees of freedom (DOF) serial manipulator is a famous robotic arm that has a vast areas of applications, not only in industrial application, but also in other fields such as medical and exploration applications. Accordingly

This work assesses the economic sustainability of industrial factories in Egypt based on the Analytical Hierarchical Process (AHP). The authors designed an economic sustainability index calculator (ESIC) using Unified Modelling Language (UML) and implemented the software using Visual basic of Applications (VBA) tool to the code the program. UML was used for the system analysis and design only

The increased usage demand for digital multimedia has induced significant challenges regarding copyright protection, which is the copy control and proof of ownership. Digital watermarking serves as a solution to these kinds of problems. Among different types of digital watermarking, visible watermarking protects the copyrights effectively, since the approach not only prevents pirates but also

Technological revolution has reached all life activities starting from day planning reaching communication, entertainment, industry, and transportation. Each of previously mentioned categories get improved in a way making human life easier and safer. In the use of automatic control, several researches focused on automating vehicles’ systems to make driving easier and safer. The availability of

Human's health information is considered momentous information, which is represented in medical systems. The amount of medical image information available for analysis is increasing with the modern medical image devices and biomedical image processing techniques. To prevent data modification from unauthorized persons from an insecure network, medical images should be encrypted efficiently. In this

Designing a proper public transportation system is a main concern for many countries with large population size like Egypt. Therefore, the online based transportation business for individuals is highly growing in Egypt and the concept of online reservation in the transportation field has arisen. In this paper, a model in the analysis phase for an online public bus reservation system (OPBRS) is

Laminar unsteady incompressible flow past two-cylinders in tandem is investigated numerically. The vortex shedding over the cylinders' arrangement is studied at various Reynolds numbers and blockage ratios while changing the distance between the two cylinders. The output from the numerical simulations is used to feed different regression methodologies to find the optimal approach for the proposed

Hitec molten salt is a ternary eutectic mixture salt that is used as an energy storage medium in concentrated solar power plants to improve the system performance and reduce the operational cost. Thus, the heat transfer performance represented in Nusselt number has been investigated numerically under different inlet temperature and velocity conditions with constant uniform side heat flux. Also

High quality education should be the top priority for any nation seeking prosperity. This paper aims to present a conceptual model for e-learning system for developing countries. This is achieved adopting an object-oriented approach and Unified Modeling Language (UML). The functional and dynamic views of the system are presented and explained within this framework. The functional system includes

A new Finite element model for HVAC applications is introduced. The model incorporates flow turbulence, buoyancy effects and unsteadiness. Also, the model accommodates complicated boundaries due to complex geometries and perforated tiles. Experimental validation is provided and extensive results for flow and temperature contours are presented. Temporal and spatial resolution prove that the model
