The main target of this paper is to allow renewable energy resources (RES) to participate eff ectively within hybrid micro grids via an optimal proportional integral- derivative (PID) controller. This paper proposes two techniques of optimal PID controllers in a hybrid renewable generation energy system. These techniques are particle swarm optimization (PSO) and lightning attachment procedure optimization (LAPO). The hybrid renewable generation energy system in this study includes a photovoltaic source, wind turbine, and battery storage, which are connected to a point of common coupling via DC/DC boost converters. The controller at the inverter consists of a current controller and voltage source controller, which results in three PID gains at each controller. In order to obtain the PID gains, a time domain objective function is formulated in terms of the voltage, and current errors. The obtained results with the individual advanced optimization LAPO and PSO algorithm are compared. The results display that the developed LAPO algorithms give better results compared to the conventional PSO at the input and output current, voltage, and power. All the results have been taken under several operating conditions of wind turbine (wind speed) and solar sun (changing irradiance and temperature).
Moments and Estimation From Progressively Censored Data of Half Logistic Distribution
Sultan, K.S.,Mahmoud, M.R.,Saleh, H.M. The Korean Reliability Society 2006 International Journal of Reliability and Applicati Vol.7 No.2
In this paper, we derive recurrence relations for the single and product moments of progressively Type-II right censored order statistics from half logistic distribution. Next, we derive the maximum likelihood estimators (MLEs) of the location and scale parameters of the half logistic distribution. In addition, we use the setup proposed by Balakrishnan and Aggarwala (2000) to compute the approximate best linear unbiased estimates (ABLUEs) of the location and scale parameters. Finally, we point out a simulation study to compare between the efficiency of the techniques considered for the estimation.

In this paper, a systematic methodology is proposed for developing an outcome-based undergraduate Industrial and Systems Engineering Program at the Systems Engineering Department of King Fahd University of Petroleum & Minerals (KFUPM) in Saudi Arabia. This program is an upgrade of the Industrial Engineering and Operations Research (IE/OR) option, which has been in existence since 1984 and has been revised several times since then. The methodology and process used is motivated by the Accreditation Board for Engineering and Technology (ABET) 2000 criteria and has been employed to develop the program’s objectives and outcomes. Subsequently, a curriculum is designed that is expected to deliver the objectives and outcomes. The paper presents the methodology, objectives, outcomes and the developed curriculum of the outcome-based program.

Background At the end of 2019, the new Coronavirus disease 2019 (COVID-19) strain causing severe acute respiratory syndrome swept the world. From November 2019 till February 2021, this virus infected nearly 104 million, with more than two million deaths and about 25 million active cases. This has prompted scientists to discover effective drugs to combat this pandemic. Area covered Drug repurposing is the magic bullet for treating severe acute respiratory syndrome coronavirus 2 (SARSCoV2). Therefore, several drugs have been investigated in silico, in vitro, as well as through human trials such as anti- SARS-CoV2 agents, or to prevent the complications resulting from the virus. In this review, the mechanisms of action of different therapeutic strategies are summarized. According to the WHO, different classes of drugs can be used, including anti-malarial, antiviral, anti-inflammatory, and anti-coagulant drugs, as well as angiotensin-converting enzyme inhibitors, antibiotics, vitamins, zinc, neutralizing antibodies, and convalescent plasma therapy. Recently, there are some vaccines which are approved against SARS-CoV2. Expert opinion A complete understanding of the structure and function of all viral proteins that play a fundamental role in viral infection, which contribute to the therapeutic intervention and the development of vaccine in order to reduce the mortality rate.

Objective: Zearalenone (ZEA) is a mycotoxin with potent estrogenic effects. Saffron is an herbal product that has antioxidant activities. The objective of this study was to investigate the protective role of saffron against reproductive toxicity induced by ZEA in female mice. Methods: Ninety 8-week-old female mice were randomly allocated into three treatment groups. The first group received an intraperitoneal injection of ZEA (2.5 mg/kg) on alternate days. The second group received ZEA (2.5 mg/kg) on alternate days plus oral saffron daily (50 mg/kg). The third group was treated with a vehicle of 1% dimethyl sulfoxide (DMSO) on alternate days, as a control. Ten mice were euthanized from each group at 30, 60, and 90 days of treatment. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol ($E_2$), and progesterone (P) were assessed. The uterus and ovaries were examined for changes in size or morphology. Results: Serum levels of LH, FSH, $E_2$, and P in the female mice treated with ZEA plus saffron were significantly higher than in those treated with ZEA alone, and were not significantly different from those treated with 1% DMSO. The female mice treated with ZEA alone showed a reduction in size of the uterus and abnormal architecture of the ovaries. Conclusion: The administration of saffron to female mice resulted in a significant reduction in ZEA-induced alterations in reproductive hormone levels, the size of the uterus, and the morphology of the ovaries.

The extracts of Carica papaya (flower), Barringtonia macrostachya (leaves), Coleus tuberosus (tuber), Mangifera indica (fruit skin) and Eugenia polyantha (leaves) showed strong in vitro anti-tumor promoting activity when assayed using Raji cells (Mooi et al., 1999). The anti-tumor promoting activity of the crude extracts was further analyzed by immunoblotting analysis of Raji cells carrying Epstein-Barr virus genome. The expression of early antigens diffuse (EA-D) and early antigens restricted (EA-R) was determined by performing western blotting of treated Raji cells with human sera of nasopharyngeal carcinoma patients. All the plant extracts were shown to be able to suppress both EA-D and EA-R.

Differential Thermal Analyzer (DTA) is an instrument used to characterize the new materials and it worksbased on the themoanalytic qualitatively technique. In this paper a digital design of a programmable temperature controller for the DTA has been presented. This programmable controller has been designed using very high speedintegrated circuit hardware description language (VHDL) and implemented in a field programmable gate array (FPGA). The heating rate of the DTA can be flexibly selected from the range between 1°C per minute and 15°C per minute. Also, the temperatures are measured with the accuracy of 0.125 degrees. The sampling time between the reference and thefeedback temperatures of the controller has been designed for 2.56 seconds. The simulations and experimental results of the proposed temperature controller are presented.
