This study applied linear programming method as an optimization package to analyze the operational processes of wheat flour mill industry, with functional models developed using defined variables constraints of wheat flour x_1, baking flour x_2 and semolina x_3 for objective functions. Furthermore, a proficient operational process of wheat flour mill industry based on raw materials requirements and production cost using linear programming method with MATLAB application to optimize the operational process of wheat flour production plant by maximizing raw material resources and minimizing production cost using a modified milling process flow chart for enhanced products yield from the milling of the whole wheat grains, and a monthly analysis of the available wheat resource for production and machine hours operated during each month. The results after computing the average supply of wheat and available machine hours as variables and modelled into linear programming equations for optimization showed increase in semolina production, reduction in wheat flour production and reduction in production cost of baking flour respectively. In addition, the profit generated showed a significant increase in the months of December at ₦164,850.00 (highest) when the machine hours and wheat available were at its peak. Thus, baking flour was found to be the least profitable among the three products monthly and recommendations suggested a reduction in its production cost to enable profitability in its production

The paper aims to evaluating the performance of palm oil based- waste cooking oil biodiesel as alternative diesel engine fuel. The methodology of the study was experimental. The waste oil was two-step transesterified and chemically analyzed to establish physico-chemical properties of biodiesel. The test fuels were evaluated for brake specific fuel consumption (BSFC) and brake thermal efficiency (ηth) at varying brake power on test rig consisting of Mazda engine coupled with a power take off propeller inserted in the power take off shape to Froude hydraulic dynamometer. The results showed that at all brake power, the BSFC decreased as strength of diesel increased in the blend. At brake power of 15KW, brake specific fuel consumption (kg/KWh) for BD25, BD50, BD75, BD100 and AGO were 0.41, 0.40, 0.38, 0.44 and 0.37 respectively. The brake thermal efficiency, at that instant of brake power of 15KW, were 22.2, 21, 20.8, 23.8 and21.5 for BD25, BD50, BD75, B100 and AGO in that order. As the load increased, brake thermal efficiency (ηth) increased for all the test fuels utilized while the brake specific fuel consumption decreases. These characteristics were closely associated with physico-chemical properties of the biodiesel. In conclusion, waste palm oil biodiesel demonstrated characteristics of lean, cleaner but high performance fuel in IC engine.

Food and drug administration (FDA) benchmark study for biomedical flow transition. An idealized medical device is presented and CFD predictions of pressure and velocity are compared against experimental measurements of pressure and velocity. The fluid flow transitions considered laminar (Re=500), transitional (Re =2000), and turbulent (Re=6500) with various turbulence fluid flow simulation models of laminar, k-omega, k-omega SST and k-epsilon based on inlet throat Reth. = 500, 2000 and 6500. Axial velocity at centreline for Reth = 500, 2000 and 6500 at line X =0, showed maximum difference of 77.4% for velocity at centerline at 0.08m and 19% for wall pressure at -0.09m sudden expansion at laminar region of Re = 500. Good agreement with simulation happened at 65.6% and 17.2% transition Re =2000. At turbulent region Re = 6500, all models were in good agreement at 49.6% velocity centerline and 8.10% pressure drop, But in laminar legion, downstream of the simulation of Reth =6500, other models disappeared which demonstrated K-epsilon model is best at higher Reynolds turbulent region. Emphatically, from 0 to -120N/m2 counterbalanced at Reth = 500 wall pressure showed negligible axial pressure gradient at centerline with drop in normalization point of experimental data.

In recent years, networked control systems have grown in importance and received increased interest as a new research subject. The process of integration of control and communication in networked control systems has posed a significant theoretical challenge for traditional control theory in terms of system design and analysis. The installation of networked control systems becomes an essential intermediate step toward the final convergence of control, communication, and computing as a result of this integration. We begin by covering the fundamentals of networked control systems, followed by an overview of current research in the subject. We hope that this brief lesson will serve as a catalyst for further research and development of networked control systems, both theoretically and in terms of practical applications.

Textile industry is a significant source of revenue in Bangladesh. More effort is being put into producing high-quality woven fabrics. The generation of fiber balls is a significant challenge in the fabrication of woven fabrics. It causes coloring issues in woven fabrics as well as fabric rejection. The method of fiber ball generation during weaving has been described in this article. The advancements in the weaving process that are required to prevent ball formation and to weave virtually flawless cloth have also been explored.

This paper presents the evolution of protective relays used for the protection of Power Transformer, Over Head Equipment (OHE) and Shunt Capacitor Bank in Indian Railways Electrical Distribution Systems. Initially during electrification Indian Railways adopted 1-Φ, 25KV, 50Hz AC system and electromagnetic relays (EM Relays) for feeder protection of OHE available at that time. But over the period of time with the drastic growth in traffic and sharp increase in demand for more electrical power to heavy goods trains haulage, the above said protective system doesn’t catered the requirements like speed, sensitivity, reliability, post fault data analysis. Hence Indian Railways over the years have undergone a paradigm shift in protective relay schemes. The journey of evolution from EM relays and static relays to the latest state of art integrated Numerical relays which were approved by RDSO are dealt here.

With the advent of multiple emerging technologies, we are on the verge of 4IR. This revolution exposes new challenges as well as exciting opportunities. Only the countries with expertise in these emerging technologies can successfully meet the challenges and exploit the opportunities. Blockchain technology is widely regarded as one of the core and foundational technologies that will be one of the driving forces for the upcoming 5IR (Fifth Industrial Revolution). Realizing its potential, many developed as well as developing countries around the world have started exploring how blockchain technology can prepare them for the future challenges and benefit them to solve many existing complex problems to achieve the SDGs (Sustainable Development Goals) by 2030. This paper is an effort to recognize the need to explore blockchain technology in order to advance its technical capacity, increase efficiency in e-Governances and foster innovations.

Project-Based Learning (PBL) is a teaching and learning approach that has many advantages for students, and it can be applied in ergonomic disciplines since they require a more innovative teaching approach. Thus, following a PBL approach and phases of concepts´ generation from the literature, this work aimed to develop a framework that connects four phases of concepts´ generation with appropriate methods. The result of this work (the framework) was applied in five case studies, with 198 students in ergonomics classes. As conclusions, it can be said that the framework directs professors in a structured way and contributes to a greater fixation of theory by students, as well as a greater understanding of their practice.

The analytical model using the Second Law of Thermodynamics is applied to determine the thermal performance of a gasket plate heat exchanger. The gasket plate heat exchanger under analysis was initially projected for milk pasteurization, with water as a refrigerant, a mass flow rate equal to 0.42 kg/s, and a few plates equal to 20. The present work aims to determine the thermal performance of the heat exchanger, varying the number of plates, the flow rate of the refrigerant fluid, and using nanofluid with variations of volume fractions of aluminum oxide. Thermal efficiency, thermal effectiveness, generation entropy rate, heat transfer rate, and refrigerant and milk outlet temperatures were determined for comparison. In addition, the physical configuration of the plate heat exchanger, concerning the size and heat exchange area of the plates, was maintained.
