ANN Control Strategy for THD Reduction in Microgrid. []


Micro-grid system is currently considered as alternate solution to fulfil the shortage of power today. It consists of several small Distributed generations integrated with storage systems to act as single entity. In a dc microgrid PWM inverter with conventional PI controller is incorporated to convert dc-ac. In this paper a microgrid is modelled with renewable energy generations such as Photo Voltaic, Wind Turbine and Fuel cell with Battery Energy Storage systems. A Neural Network control is implemented with ten-layer network to generate the pulses to control the voltage and current harmonics. The model is developed in MATLAB/Simulink and the results are compared with the conventional PI controller and analysis is made that the ANN controller improves the inverter performance.

Evaluation and Selection of Contractors for Petroleum Projects in Egypt Using Multi Criteria Decision Making (MCDM) Techniques []


Selection of the best-value contractor is pivotal to all industries, especially those involving various stakeholders and costing billions of dollars. The best-value contractor is defined as the one that can achieve the perfect combination of requirements that ensure the successful implementation of the project within a realistic cost and acceptable quality. Although it may incur extra costs, to the owners, due to reworks and incomplete project scope, the lowest bid method has been adopted for awarding project contracts in the Egyptian market, especially in the public sec-tor. The oil and gas industry is the lifeblood of industrialized nations; hence, successful delivery of the complete project scope according to the required standards and technical specifications is extremely crucial. Investigation of the best-value contractor selection approaches within the oil and gas market has been scarcely discussed in the literature. The current study fills this knowledge gap by employing multi-criteria decision-making (MCDM) techniques to provide a decision support tool for contractor selection within the Egyptian oil and gas sector. The MCDM techniques include the analytical hierarchy process (AHP); the technique of order preferences by similarity to the ideal solution (TOPSIS); the weighted sum method (WSM); and the weighted product method (WPM). The study has been deployed on two actual petroleum sector projects in Egypt. The results confirm that the AHP technique provides a significant benefit by considering the individual preferences of all decision-makers (i.e., bidding committee members when weighting the criteria) mitigating the drawbacks of the existing methodologies. The results also confirm that MCDM techniques of TOPSIS, WSM, and WPM have captured all the decision-makers’ preferences of bidders where the best-qualified bidder is the one achieving the required combination of requirements to execute the contract. In conclusion, MCDM techniques provide an advantage over the lowest bid strategy as they provide a valuable tool for decision-makers to select best-value contractors.

Policy Analysis of BRIN's Talent Management Program for The Performance Target Achievement of Indonesian Science and Technology Human Resources []


The National Research and Innovation Agency (BRIN) is an Indonesian government agency responsible for science and technology, has formulated several strategies to achieve strategic targets and performance indicators as stated in the BRIN Strategic Plan 2022-2024, and efforts to realize Indonesia's 2045 vision, especially the pillars of Human Development and Mastery of Science and Technology. There are a number of challenges to implementing this policy, for example the lack of science and technology human resources (Researchers, Engineers, etc) with doctoral qualifications, there are only 10.56%, far from the BRIN target for 2023 of 18% and 20% in 2024. BRIN has developed a strategy to realize this goal, for example recruiting researchers with doctoral qualifications. In addition, BRIN also has 6 (six) programs related to the research mobility strategy. The initial evaluation process has been carried out in 3 (three) programs. In the Independent Learning Campus Merdeka (MBKM), Research Assistant (RA), and Research Talent and Innovation (BARISTA) programs there are still various problems, such as the lack of response from researchers in the Research Organization Unit, unclear target number of participants, inefficient administration process, special problems regarding financial aspects and allowances, monitoring and evaluation system constraints, problems related to information technology, output proposal constraints, the BRIN internal research group admitted that they were not familiar with this program, constraints on the comprehensiveness of planning documents (technical instructions, or implementation). These various problems must be fixed immediately, so that the program can run more optimally in the future. Optimization steps need to be carried out on aspects related to program socialization, financial support or appreciation, mechanisms for resolving administrative problems to support the smooth running of the program, improving planning documents, implementation or technical guidelines, clear target participants, improving the quality of monitoring and evaluation systems, improving the quality of information technology the policy evaluation process at the beginning of the program is expected to achieve improvements in the quality and sustainability of the talent management program at BRIN.

Correlation of Workplace surveillance with Psychological Health, Productivity, and Privacy of employees. []


“Employee monitoring has raised concerns from all areas of society – business organizations, employee interest groups, privacy advocates, civil libertarians, lawyers, professional ethicists, and every combination possible. Each advocate has its own rationale for or against employee monitoring whether it be economic, legal, or ethical.” (Martin & Freeman, 2003). Surveillance plays an important role in managing the scenario of business and employment. No one likes to be under the watchful eye of the company's surveillance, but it is difficult to discuss surveillance without considering all sides of the subject. In the future, there will be more behind-the-desk jobs than field jobs and companies would be surveilling the employees more often (Obudho, 2017). Firms use numerous methods to control employees’ activities to ensure increased productivity, performance, and profitability (Gichuhi, Senaji, & Ngari, 2016). Through employee engagement in the workplace there is assurance that employees are committed to their organizational goals, and values, motivated to add to organizational achievement, and at the same time to improve their individual sense of well-being (Gichuhi, Senaji, & Ngari, 2016). To achieve an optimal workplace surveillance system, companies use different techniques from simple camera monitoring to complex systems consisting of email monitoring, phone call monitoring, screen sharing, etc. Organizations use surveillance to increase efficiency, reduce risks, and maximize profits (Alex Rosenblat, 2014).

The Human Firewall []


Hackers / fraudsters frequently use Phishing, Vishing, Smishing and social engineering attacks to gain an access into a target system or network. This type of attack is a marvellous challenge to protect, as the weakness mostly lies within us (humans), not in the technology. A robust security system contains more than just hardware or software; there must always be a “wetware” defence element as well. The “human firewall” is a concept in security awareness that enables a team to fight against hackers in a proactive as well as reactive fashion. The first part of the research is targeted in creating a safer connected world by protecting our customers, ourselves, and the future from all possible form of Cybercrime to be one step closer to be the best-connected Company across the globe. By deploying a simple 18-month plan to build and deploy the Human Firewall, With the Sponsorship of Kevin Brown - Director of BT Security to start off with the feasibility check of the research with the team. Through this research currently we are deploying the brilliant Human Firewall for our internal customers and Our People. Through our internal workplace group, we did a trial with our brilliant community members who shared their opinion and some great feedback which helped us a lot. This research shows the importance and usefulness of Human awareness to build and deploy the strongest Human Firewall across BT. The benefit is not only limited to design and manage employee behaviour but also it has a huge impact on the personal front of all the employees to spread awareness across all their loved ones, friends, and family members to stay safe from all these cyber-attacks.

Factors Affecting Inflation Rate – Evidence from Pakistan by ARDL Approach []


The economy of Pakistan is suffering from many economic problems and in this regard inflation is also one. So, it is an attempt to capture the actual determinants of inflation by taking supply of money, population growth rate, imports of agricultural inputs, government expenditures and exports as an independent variable and consumer price index as proxy variables for inflation. These independent variables are significantly at the back of this problem and this study proposed how government can control the high price level to maintain the high living standard for the common people. We can say that it is an attempt to see how these independent variables are determining the inflation in the economy of Pakistan. Key words: inflation, supply of money, population growth, exports, imports JEL Code: G2, R23, Q41, F1

A Deep Learning Model for Detecting Anomalies in the Banking Sector Using A Feed-Forward Neural Network []


The evolution of anomalies in the banking sector has resulted in the execution of several criminal activities in cyberspace. Since several users go online to access the services offered by government and financial establishments, there has been a considerable growth in malicious website attacks over the past few years. In other to solve this problem, this paper presents a Deep-Learning model for detecting anomalies (e-banking phishing, and fraudulent transactions) on two datasets. The datasets were segmented into X_train and y_train, X_test and y_test which holds 60% data for training and 40% testing data. The system model was trained by using the Feed Forward Neural Network, which had a precision of approximately 97% on the phishing dataset and 99% on the fraudulent dataset. The trained model was exported to the web using flask, which is a suitable python framework for web applications so that users can check for malicious websites and legitimate website URLs. The work can be extended further by training other models and employing different machine learning algorithms to determine the algorithm with the optimum accuracy result.
