Corrosion behavior of aluminum alloy joined by activated gas tungsten arc welding أبوسفيان محمد ويس

Aluminum and Aluminum alloys are used extensively in different industries such as transportation, automotive, marine and architectural applications owing to their good mechanical properties, light weight, high strength, appropriate weldability, high toughness, and their excellent corrosion resistance. As a part of the fabrication process, welding is one of the most important manufacturing technologies used in the aluminum alloy industry. However, the welding process can change the microstructure of aluminum alloy and chemistry of aluminum alloy, and could lead to deterioration in mechanical properties and affect the corrosion behavior of Aluminum alloys.
The purpose of this research is to study the corrosion behavior and the mechanical properties of welded Aluminum alloy.

SPARE PARTS MANAGEMENT BY USING ANALYTIC HIERARCHY PROCESS خالد محمد سليمان جادالمولى
Spare parts management plays an important role in achieving the desired plant availability at an optimum cost.  It has been observed in many industries that the non-availability of spare parts, as and when required for repairs, contribute to as much as 50% of the total down time and also cost more than 50% of the total maintenance cost. Therefore, the first objective of this paper is to identify the control characteristics of spare parts such as criticality and specificity.  The second objective is to propose a multi-criteria decision making model to quantify the criticality of spare parts.  The third objective is to propose a multi-criteria decision making model to develop a manufacturing strategy of spare parts.  The proposed models are based on the analytic hierarchy process (AHP) using the Expert Choice software.  Finally, a case study will be conducted at general water desalination establishment to validate the proposed models.  These models will help the decision maker to select the right strategy which will lead to reduce the total down time and total maintenance cost.  ...
AN EFFECTIVE GREEN SUPPLY CHAIN AT ENERGY PRODUCTION خالد محمد سليمان جادالمولى
There is a national and international move towards green energy production and supply chains. Achieving an effective green supply chain at production energy consists of two main steps. This paper will concern of the first step, which includes the identifying of the green requirements (GR) and green factors (GF) of green supply chain, determining GRs priority weights, and testing the stability of the environmental requirements priority ranking. Therefore, the first objective of this paper is to identify GRs and GFs. The second objective is to propose a multi-criteria decision making model to determine GRs priority weights. The third objective is to perform a sensitivity analysis to test the stability of the environmental requirements priority ranking. Finally, a case study will be conducted at power energy industry to validate the proposed model. This model will help the decision maker to achieve an effective green supply chain at energy production. ...
Effect of Laser Speed on Hardness and Corrosion Resistance of Similar and Dissimilar Stainless and Carbon Steels Welding خالد محمد سليمان جادالمولى
The present study was undertaken to investigate the effect of laser welding speed on the hardness and corrosion resistance of similar and dissimilar materials. Similar and dissimilar Sheets from stainless steel 304 and plain carbon steel A36 are laser welded. Laser welding are carried out at different speed. Hardness measurements (micro and macro Hardness HV) are performed on all specimens after laser welding with different conditions. Linear polarization and Tafel plot tests are performed on welded specimens. Regression equations and experimental correlations between welding speed, hardness and corrosion resistance are developed. ...
Identification of fault location in a Multi-Terminals Network using Morphological Gradient Technique خالد محمد سليمان جادالمولى
This paper presents a simple, effective and fast technique based on morphological gradient to identify fault location in a multi-terminals network. Mathematical Morphology Gradient (MMG) relaying algorithm and other related algorithms such as tripping and fault location schemes are also presented in this paper. The proposed technique relies on measuring the minimum stamping time between relay indices to identify the faulty zone. The technique is evaluated through extensive simulation study using alternative transient program (ATP). Simulation results show that, the proposed technique has the capability of monitoring complex power systems and effectively identifying fault location in real time. ...
A new current-based technique for discriminating between internal faults and inrush current within power transformers خالد محمد سليمان جادالمولى
ABSTRACT: In rush current may lead to a false operation of the power transformer differential protection relay. Hence, it is very essential to distinguish in rush current from various internal transformer faults in order to improve the reliability of the differential protection scheme. This paper presents a new current-based technique to discriminate transformer inrush current from transformer internal faults. The proposed technique relies on converting the three phase transformer currents on both sides into modal current components using Clarke’s transformation to produce three current modes, namely, ground mode, aerial mode 1 and aerial mode 2. The features extracted from the three modes are then applied to the inrush discrimination equation proposed in this paper. The robustness of the proposed technique is evaluated through extensive simulation studies on a 132/15 KV, 155MVA power transformer using an Electromagnetic Transient Program (EMTP-ATP). Simulation results show the effectiveness of the new proposed technique in discriminating magnetizing in rush current from other transformer internal faults. ...
Computational Intelligence & Intelligent Systems Research Group a.iliyasu

The Computational Intelligence & Intelligent Systems (CIIS) Research Group is a newly established group funded by the Prince Sattam Bin Abdulaziz University (PSAU) via the Deanship for Scientific Research (DSR).

Computational intelligence (CI), as a discipline, refers to a set of nature-inspired paradigms that allow a computer to learn a specific task from data or experimental observation. The process might be too complex for mathematical reasoning, it might contain some uncertainties during the process, or the process might be stochastic in nature [2]. In solving these problems, ci methodologies adopt reasoning that mimics human thought using non-exact and non-complete knowledge to adaptively control actions.

To surmise, CI could be seen as the use of computing resources to resolving complex problems in a manner that mimic human thought and approach. Indeed, this is the intelligence intended in CI.

Intelligent systems are systems that rely on the use of CI (and artificial intelligence (AI)) methodologies to observe, learn and act upon environmental considerations. In other words, IS use knowledge learned to emulate the decision-making ability of a human expert. Most intelligent systems are developed based on the DRP principle - deduction, reasoning (or learning) and problem solving/decision making steps.

 Today, intelligent systems are in almost every aspect of human life ranging from medical diagnosis, autonomous device and operations, robotics, navigation, communication, warfare, gaming, etc.

Combined, the twin concepts of computational intelligence (CI) and intelligent systems (IS) connote the use of the CI methodologies (hard or soft) to realise systems capable of or surpassing human thought and reasoning...
