Abstract: Color blindness, or color vision deficiency, is an inability to see the difference between certain colors. Men are more likely to be born with color blindness. Most people with color blindness can't distinguish between certain shades of red and green. Less commonly, people with color blindness can't distinguish between shades of blue and yellow. For that it’s a significant barrier to effective computer use. Several research works dealing with blind color user interfaces are currently conducted. However, requirements engineering for such interfaces is still missing. The work presented in this paper is part of an automated blind color user interface generation project which explores suitable input requirements document notations, simplifies the generating process, and outputs generated color blind user interface. It aims to define functional and nonfunctional requirements for powerful color blind user interface and their UML specification. Thus, different recent techniques that deal with these interfaces are selected according to their relevance and up to date, then they are analyzed, the lack of requirements engineering for these interface was stated, and a solution is proposed. It consists of requirements elicitation and specification with UML notations. A case study evaluating the proposed approach is presented. The obtained results confirm the power and positive impact of such requirements engineering on researches in this domain.

Abstract: The feature model is one of the most important concepts in software product line development process, as it helps to represent commonalities and variabilities among software products. Several research works are currently conducted to generate a feature model of a software product line from its requirements document. However, the generated feature models do not include data and actors aspects which are essential parts of any software product line. The work presented in this paper is part of an automated feature model generating project which explores suitable input requirements document notations, simplifies the generating process, and outputs generated feature model formalism. It aims to propose a powerful feature model that should be the target of any automated process generating a feature model. Thus, in this work, different recent techniques that automatically generate feature models are analyzed. The lack of data and actors in these generated feature models was stated, and a feature model, aimed to be a good generated target, integrating data and actors with other conventional features is proposed. A case study evaluating the proposed target feature model formalism is presented.

Abstract: The Goal Model (GM) of software is one of the important concepts in the software requirements specification, as it helps in representing the software goals and the relationships between them. Several research works were conducted to generate GM of software from its requirements document. However, the generated GMs merge behavior and soft goals aspects. This merging leaded to tangled and complex generated GMs that are difficult to maintain. The work presented in this paper proposes a GM formalism handling this insufficiency. It is part of an automated GM generating project where it focuses on the target GM. Thus, in this work, different recent techniques that automatically generate GMs are analyzed, their merging, tangling, and complexity of maintenance were stated, and a GM formalism facing these challenges is proposed. It separates goals clearly into behavior goals, soft goals, and constraints aspects. An evaluating case study, which is a partial concrete and real word domain requirements specification, is presented. This separation of concerns leaded to valuable results: complexity reduction, improvement of the understandability, simplicity of maintenance, and raising up the expressiveness power.

Abstract: Most large-scale systems including self-adaptive systems utilize feature models (FMs) to represent their complex architectures and benefit from the reuse of commonalities and variability information. Self-adaptive systems (SASs) are capable of reconfiguring themselves during the run time to satisfy the scenarios of the requisite contexts. However, reconfiguration of SASs corresponding to each adaptation of the system requires significant computational time and resources. The process of configuration reuse can be a better alternative to some contexts to reduce computational time, effort and error-prone. Nevertheless, systems’ complexity can be reduced while the development process of systems by reusing elements or components. FMs are considered one of the new ways of reuse process that are able to introduce new opportunities for the reuse process beyond the conventional system components. While current FM-based modelling techniques represent, manage, and reuse elementary features to model SASs concepts, modeling and reusing configurations have not yet been considered. In this context, this study presents an extension to FMs by introducing and managing configuration features and their reuse process. Evaluation results demonstrate that reusing configuration features reduces the effort and time required by a reconfiguration process during the run time to meet the required scenario according to the current context.

Research Title: Numerical Experiments on the Optimum Design and Location of a Passive Vibration Absorber Applied to Multi Degrees of Freedom System Under Base Excitation

Abstract: Numerical experiments are used to investigate the optimal design parameters and the location of a passive vibration absorber and its application to reduce resonant vibration amplitudes of a base excited, discrete, Multi Degrees of Freedom (MDOF) vertical system. Attaching a passive vibration absorber (simple undamped resonator) to the system’s end mass (top mass) is preferable when dealing with the vibrations of multi degrees freedom systems. As the absorber is moved closer to the primary system's farthest end, the amplitude reduction results get better. The numerical analysis is less sensitive to slight variations in mass ratio than minor variations in the absorber’s natural frequency, according to perturbation analysis on two degrees of freedom system. Introducing damping to the used passive vibration absorber has no discernible effect on the absorber’s effectiveness

Research Title: Development of Polymeric-Based Formulation as Potential Smart Colonic Drug Delivery System

Abstract: Conventional oral formulations are mainly absorbed in the small intestine. This limits their use in the treatment of some diseases associated with the colon, where the drug has to act topically at the inflammation site. This paved the way for the development of a smart colonic drug delivery system, thereby improving the therapeutic efficacy, reducing the dosing frequency and potential side effects, as well as improving patient acceptance, especially in cases where enemas or other topical preparations may not be effective alone in treating the inflammation. In healthy individuals, it takes an oral medication delivery system about 5 to 6 h to reach the colon. A colonic drug delivery system should delay or prohibit the medication release during these five to six hours while permitting its release afterward. The main aim of this study was to develop a smart drug delivery system based on pH-sensitive polymeric formulations, synthesized by a free-radical bulk polymerization method, using different monomer and crosslinker concentrations. The formulations were loaded with 5-amino salicylic acid as a model drug and Capmul MCM C8 as a bioavailability enhancer. The glass transition temperature (Tg), tensile strength, Young’s modulus, and tensile elongation at break were all measured as a part of the dried films’ characterization. In vitro swelling and release studies were performed to assess the behavior of the produced formulations. The in vitro swelling and release evaluation demonstrated the potential ability of the developed system to retard the drug release at conditions mimicking the stomach and small intestine while triggering its release at conditions mimicking the colon, which indicates its promising applicability as a potential smart colonic drug delivery system.

Abstract: This paper deals with smart home energy management through load scheduling and optimal use of available energy sources. In this study, three energy sources were considered: the national electricity grid, photovoltaic (PV) energy, and the storage unit. The PV array can provide the maximum power to the load at a given operating point where the output power changes with temperature, radiation and load. Therefore, a real-time controller is proposed to track the maximum power. An energy management algorithm has been proposed in a smart home to achieve the main goal of making the electricity bill as low as possible. The algorithm involves scheduling loads by assigning a priority to each load. The loads are supplied with the required power according to their priorities and the available energy. The obtained results indicate that supplying the PV system with a fuzzy-based MPPT indicates an increase in system efficiency. The results also showed that the use of energy management based on load scheduling led to a significant reduction in the electricity bill.

Abstract: Extensive research and development in the processes of production and generation of hydrogen are needed to make renewable hydrogen cost-competitive with fossil hydrogen. As a result, developing hydrogen energy from low-cost components and synthesizing it from renewable resources is an important issue that can be considered a global challenge. The current research provided a continuous H2 energy production from waste aluminum in a water medium using copper oxide nanoparticles (CuO NPs) as catalysts in the reaction. CuO NPs have been prepared by a green, easy, inexpensive, and systematic method using Catha edulis L. (Khat) extract as reducing and capping agents. Separately, CuO NPs prepared in an alkaline media using the conventional hydrothermal process have been described and reported for comparison. Multidisciplinary tools were used to characterize the powders for structural, morphological, and surface aspects. CuO NPs were homogeneous, well-dispersed, and have fine diameters with an average of 6 nm, owing to the abundant biomolecules in the plant extract. The synthesized samples were utilized as catalysts for H2 production from industrial waste aluminum with a 1/0.02 ration of Al/CuO by weight. The primary results revealed a higher H2 production yield and rapid rate in alkaline than acidic mediums. Under all conditions, the CuO NPs prepared from the extract had better catalytic activity than those prepared by a conventional method. The results proved that the reaction temperature prompts the reaction kinetics more than other parameters. The optimum H2 yield could be optimized at a temperature of 70C, 1/50 ratio of CuO/waste Al, and near-neutral solutions. The above conditions are ideal for designing a continuous production reactor. The hydrogen generated using industrial waste aluminum in the present system is a cost-effective and sustainable approach.

Faculty: Engineering and Technology

Abstract: Experimental work has been carried out to study the possibility of combining a conventional solar water collector with a hybrid device, developed previously and known as PV/T system, in order to obtain hot water with temperature above 40 °C. The effect of the combination on the productivity of hot water and the produced electricity was found. The formerly developed device, in which there was a multi-purpose solar collector, can produce hot water and electricity. It was connected to the conventional fn-tube collector in series in order to raise the product temperature to a higher level. This development was achieved for the frst time as a combination between a PV/T and a conventional fn-tube collector. Instrumentation to measure temperatures, solar radiation, wind speed and flow rate was installed on the system. It was found that the water temperature was raised from 29 °C to 32 °C in the PV/T collector system and, after flowing through the conventional collector, it was raised to 50 °C and above. It was also found that the power efciency in the case of water flow is always higher than in the case of no water flow.
