In the current practical science, the accuracy in the formability of metal alloys being the goal when using electromagnetic forming (EMF) technology, which is a high-speed processing technology that uses Lorentz forces to achieve plastic deformation of sheet metal;according to the previous analysis, the results have shown that in most cases, the Lorentz force acting on the workpiece (metal) is not uniform, there are uneven axial deformations of the metal plates which prevent the rapid advancement of today’s technology. In this article, we presented some advanced analyzes which will lead us to improve the technical solution for the problems of non-uniform axial deformations of the metals in the traditional tube electromagnetic forming technology (EMF). A field shaper is used as a practical forming tool to influence the magnetic field and magnetic pressure distribution, thereby improving the forming ability and result during the electromagnetic forming (EMF) process and we see that induced eddy current control is realized by changing the structural parameters of the magnetic field shaper;which improves the strength and controllability of the magnetic force that acts on the workpiece;thereby a greater radial magnetic pressure can be achieved with field shaper than the case without it;the field shaper regulates the electromagnetic force, the distribution of the magnetic pressure decreases, and the uniform force area of the tube increases which effectively enhances the uniform range of the pipe electromagnetic bulging and the electromagnetic induction coupling between the coil and the metallic workpiece is generally required to produce the Lorentz forces. Using COMSOL Multiphysics® simulation software helped us to accurately represent the real world, simulating multiple physical effects that happened in this model during the process.

This paper proposes a technique for indoor localization based on a visible light positioning approach. The strategy relies on using lighting luminaires that modulate the luminous flux at different frequencies. A light sensor is then used to gather the illuminance signal used as input for a previously trained Artificial Neural Network (ANN) to estimate the position of the sensor. The work's main contribution is using an illuminance estimator based on the lighting distribution of the luminaires to perform the training procedure of the ANN. The lighting distribution is obtained through the .IES file provided by the manufacturer, i.e., the same file used for lighting designs. Therefore, by using characteristics of the environment and the .IES file, the proposed system can provide data to train accurately the ANN used in the positioning method. The results attested to the satisfactory performance of the proposed localization technique as it produced mean distance errors of 1.51cm and 0.79cm considering 0% and 70% walls' reflectance levels, respectively.

The components outage of an energy system weakens its operation probability, which can affect the sizing of that system. An optimal sizing framework is presented for an autonomous hybrid photovoltaic/hydrokinetic/fuel cell (PV/HKT/FC) system with hydrogen storage to supply an annual load demand with forced outage rate (FOR) of the clean production resources based on real environmental information such as irradiance, temperature, and water flow. The sizing problem is implemented with the objective of cost of energy (COE) minimization and also satisfying probability of load supply (PLS) as a reliability constraint. The FOR effect of the photovoltaic and hydrokinetic resources is evaluated on the hybrid system sizing, energy cost, reliability, and also storage contribution of the system. Meta-heuristic horse herd optimization (HHO) algorithm with perfect capability on exploration and exploitation phases is used to solve the sizing problem. The results proved that the PV/HKT/FC configuration is the optimal option to supply the demand of an autonomous residential complex with the minimum COE and maximum PLS compared with the other system configurations. The results demonstrated the overlap of hydrogen storage with clean production resources to achieve an economic-reliable power generation system. The findings indicated that the COE is increased and the PLS is decreased due to the FOR increasing because of reducing the generation resources operational probability. The results demonstrated that the hydrogen storage level is increased with FOR increasing to maintain the system reliability level. © 2022, The Authors. All rights reserved.

Because of the harsh environmental impacts of fossil fuels, price fluctuation, and resource limitation, renewable energy resources (RERs) are considered the ultimate solution to overcome these challenges. RERs are also abundant and environmentally friendly. It has been reported that the growth rates in renewable energy installations have increased by 8–9% annually since 2010, reaching a cumulative capacity of 2.9 TW by 2020 and exceeding the growth rate for fossil resources. In this work, the different RERs have been critically discussed in terms of their operation principles, advantages, disadvantages, and associated environmental impacts, focusing on wind and solar energies as the most deployed RERs. Barriers to the full deployment of RERs to replace fossil resources are discussed. Based on the discussion presented on RERs, the contribution of deploying RERs towards the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) is also critically discussed. A total of 80 indicators have been identified for RERs' contribution toward the achievement of SDGs. © 2023 The Author(s)

Transitioning the energy sector to zero or net-zero emission of greenhouse gasses (GHG) and substantially reducing other pollutants is a massive, costly, and long-term effort. The typical starting point and centerpiece of energy decarbonization is the electric power sector. The sector is a large direct GHG emitter. It already has many technological, non-carbon emitting alternatives that are rapidly declining in capital and operating costs and improving in performance, making electricity the least expensive and accessible energy carrier to decarbonize. This paper explores what the modeling community should do to inform this transition. The underpinning premise of this paper is that policymakers genuinely want to be informed from the modeling community about their range of options, their ability to achieve various objectives, and possible unintended outcomes. Since the goal of the modeling community is to help inform policymaking, it is important that they hear the needs of policymakers, be it economic, technological, or social goals. © 2021 Elsevier Inc.

This paper introduces a first and second law based transient mathematical model for 4-stroke compression ignition internal combustion engines (CI-ICE) driven by diesel/biodiesel/biogas mixtures to allow for the maximization of system performance. In this way, the CI-ICE morphology that provides easier access to the currents that flow through it is sought, according to constructal law. The total entropy generated in the CI-ICE cycle was calculated by adding the entropy generation in all strokes. An optimization problem was formulated based on the variation of operating and geometric parameters, and the objective functions were the effective and 2nd law efficiencies, and , as well as the destroyed exergy fraction, . The optimal ranges found for the bore-stroke, compression and conrod-crank ratios were;, and in which with for D100 (pure diesel), and with for B50D25NG25 (biodiesel/diesel/natural gas blend). The maxima and minimum found were sharp, since and varied up to 71% and 69% in comparison to their maximum values, respectively, and up to 45% in comparison to its minimum value within the adopted ranges of variation of the optimized parameters. Such large variations stress the importance of considering the optimized CI-ICE morphology in actual design, i.e., CI-ICE constructal design. © 2024, The Authors. All rights reserved.

The accuracy of weather-dependent power flow analysis for large interconnected systems can be significantly improved by including more electrical devices exposed to weather variables such as ambient temperature, wind speed and solar irradiance. The innovative part of the proposed approach is the combination of factors such as a voltage regulating transformer model, freely available weather data to feed the weather-dependent power flow algorithm, and a geographic visualization tool to display the results. To demonstrate the effectiveness of the proposed approach, the IEEE 118-bus system is used to analyze and compare the results of the weather-dependent power flow model versus a conventional power flow. In this case, it is used in the stationary analysis, the power flow temperature algorithms are performed in spatial visualization schemes. The results show that weather conditions directly affect the power system performance

Energy demand is increasing and it raise a climate change issue. Greenhouse emissions, depleted fossil energy resources, increasing fossil energy cost are reasons to maximize the utilization of renewable energy source. Hydropower extend an alternative energy source to cover the growing energy demand and release no emission at the same time for maintaining the climate change. In recent years, major focus of hydropower research is moving to small hydropower, as large hydropower opportunities are exploited and have high capital expenditure to build. A water vortex stream is a common phenomenon that we can see everyday life. Water flow out from the bathtub through outlet or water flow down in the sink after we finish washing the dishes, that is what we call vortex flow. and is a free-surface flow, homogenous fluid that contained water and air. This water vortex can be applied in low head small hydropower plant, recently known as gravitational water vortex power plant. River off Gravitational Water Vortex power plant (GWVPP) is one of low head turbine that can be used to generate electricity in small scale, pico-hydro. This study is focus on basin geometry. Models are developed to investigate the outlet diameter, depth discharge and basin geometry. It is found out that parameter of the basin should refer to source, which are flow rate, and the head of the water. It shows that spiral geometry for the basin gives symmetric and strong vortex and can be used as an alternative of conical basin. © 2020 IEEE.

Development program for construction of irrigation channel gives big opportunity for development of renewable energy from small low head hydropower source. The use of hydropower gives no negative impact to environment, especially for greenhouse emission. A gravitational vortex hydropower is the object of this study, with the focus on the water intake channel using rectangular geometry. An experimental study was conducted to find the influencing parameters on the intake section of the gravitational vortex hydropower. A set of parameters were varied to determine which parameters affecting the water surface at the intake channel. By analyzing the results of the experiments, the influence of parameters on the water intake channel of gravitational vortex hydropower was found. A performance curve for differentiation of flow type and identification of surface contour has been made. Based on the results of the experiment, placing a strainer at 5 cm distance gave 60% higher output power since this setting could reduce the wave speed. Recommendation to have further study in non-dimensional parametric should be considered for increasing efficiency of the gravitational vortex hydropower. © 2020 IEEE.

Significant population and economic growth, caused increasing of energy demand. Depletion of fossil fuel moreover coupled by climate change issue that caused by increasing carbon emission, become necessity to continuously encourage achieving renewable energy mix in energy primer. Large potentials of hydro renewable energy source and small utilization of it, micro-hydro and pico-hydro power plant are suitable to develop especially in country side. The research gap in the current turbine application chart is a challenge for Gravitational Water Vortex power Plant (GWVPP) strong existence in pico-hydro power, besides conventional turbine design has been developed into it. However, development in vortex flow and basin geometry design has a robust design for the past 10 years of research. Researches have been conducted in few countries that proofed GWVPP has less capital investment and low operational and maintenance cost, however the parameter of the GWVPP still need further development since the power output efficiency still low. Since basin opening and outlet diameter are the main parameters to define basin geometry, inlet channel need to do further research. The research will improve the recent gaps;therefore, vortex turbine could be developed accordingly that would result immediate improvements for renewable energy growth in Indonesia through GWVPP. © 2020 IEEE.
