TL;DR: In this paper, a simplified cost minimization methodology based on the thermoeconomic concept is applied to calculate the economic costs of all the internal flows and products of the system by formulating thermo economic cost balances.
Abstract: In this paper, the thermoeconomic concept is applied to the optimization of a double-effect H 2 O/LiBr VAR system, aimed at minimizing its overall product cost. A simplified cost minimization methodology based on the thermoeconomic concept is applied to calculate the economic costs of all the internal flows and products of the system by formulating thermoeconomic cost balances. Once these costs are determined, the system is thermoeconomically evaluated to identify the effects of the design variables on cost of the flows and products. This enables to suggest changes of the design variables that would make the overall system cost-effective. Finally, an approximate optimum design configuration is obtained by means of an iterative procedure. The result shows significant improvement in the system performance. The sensitivity analysis shows that the changes in optimal values of the decision variables are negligible with changes in the fuel cost.

TL;DR: A modified CSO is being proposed in this paper where two thirds of the population swarms are being updated by a tri-competitive criterion unlike CSO, which confirms the superiority of MCSO over many other state-of-the-art meta-heuristics, including CSO.
Abstract: Display Omitted The proposed work (MCSO) is motivated by the Competitive Swarm Optimizer (CSO).2/3rd of the swarm are updated in MCSO every time by a tri-competitive criteria.Both CEC 2008 and CEC 2010 benchmark functions have been solved using MCSO.Statistical results confirms the superiority of MCSO with faster convergence rate.Clearly, MCSO maintains good balance between exploration and exploitation search. In the recent literature a popular algorithm namely Competitive Swarm Optimizer (CSO) has been proposed for solving unconstrained optimization problems that updates only half of the population in each iteration. A modified CSO (MCSO) is being proposed in this paper where two thirds of the population swarms are being updated by a tri-competitive criterion unlike CSO. A small change in CSO makes a huge difference in the solution quality. The basic idea behind the proposition is to maintain a higher rate of exploration to the search space with a faster rate of convergence. The proposed MCSO is applied to solve the standard CEC2008 and CEC2013 large scale unconstrained benchmark optimization problems. The empirical results and statistical analysis confirm the better overall performance of MCSO over many other state-of-the-art meta-heuristics, including CSO. In order to confirm the superiority further, a real life problem namely sampling-based image matting problem is solved. Considering the winners of CEC 2008 and 2013, MCSO attains the second best position in the competition.

TL;DR: Simulation results suggest that proposed scheme is working satisfactorily and Lyapunov stability theory is used and required condition is derived to ensure the stability of error dynamics.
Abstract: This paper aims at synchronization and anti-synchronization between Lu chaotic system, a member of unified chaotic system, and recently developed Bhalekar–Gejji chaotic system, a system which cannot be derived from the member of unified chaotic system. These synchronization and anti-synchronization have been achieved by using nonlinear active control since the parameters of both the systems are known. Lyapunov stability theory is used and required condition is derived to ensure the stability of error dynamics. Controller is designed by using the sum of relevant variables in chaotic systems. Simulation results suggest that proposed scheme is working satisfactorily.

TL;DR: In this article, the authors discuss the effect of COVID-19 on socioeconomic implications and the impact of lockdown on the food supply chain and agri-business and summarize the suggestions needed to control and deduce the impact.
Abstract: Background The COVID virus epidemic has produced another era on the planet while we sort out the outcomes in various parts of our everyday life. The food industry and food supply chain do not incorporate an exception. Considering a food supply chain, the business activities and supply of various food products have been suspended due to restriction of demand, closing the food production facilities, financial restrictions. Scope and approach According to the spreadability of the pandemic, every nation must understand the seriousness of the circumstance. This work aims to discuss the effect of COVID-19 on socioeconomic implications and the impact of lockdown on the food supply chain and agri-business. The paper also summarizes the suggestions needed to control and deduce the impact of COVID-19. For now, the chance of transmission through the food area is viewed as immaterial, and following Covid in workspaces isn't considered as a need by public authorities. However, the unfriendly impacts on the climate, food frameworks and individuals along the food store network are obvious. Key findings and conclusion A food supply chain facilities should concentrate on facilities like maintenance of employees' safety and health, change of conditions in working. To prevent the increment of food prices, the protectionist policy should avoid. We have also suggested a PDS system to overcome food supply chain disruption. In conclusion, the supply chain should respond and overcome the challenging situation in the food supply chain.
