Modular design of battery pack for electric vehichle (EV) is an important things to consider. Because in modular battery pack, cost to manufacture can be reduced also easiness in handling. Modular battery pack also meant to be easily swapped between every modules. In this paper were presented the thermal analysis of modular battery pack that generate heat during charging or discharging process. Heat flux generated by the batteries will affect its surrounding thus increase the temperature of the batteries. Thermal analysis simulation were conducted to understand the thermal behaviour of the battery module. Thus the heat generated not exceed the maximal operational temperature of the battery cells that can reduce the battery life. The simulation is done by analyzing the heat power generated by the cells, the effect on surrounding air, and heat generated by the current flow in the circuit. Simulation result were showing that the the thermal behaviour of the module battery can be secured under its maximal operating condition. Because thermal stability having the largest effect on reliability on operational condition of battery pack. © 2019 Published under licence by IOP Publishing Ltd.

Background Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021. Methods We used the Cause of Death Ensemble modelling strategy to analyse vital registration data, verbal autopsy data, mortality surveillance data, and minimally invasive tissue sampling data. We used DisMod-MR (version 2.1), a Bayesian meta-regression tool, to analyse incidence and prevalence data identified via systematic reviews, population-based surveys, and claims and inpatient data. We calculated diarrhoeal disability-adjusted life-years (DALYs) as the sum of years of life lost (YLLs) and years lived with disability (YLDs) for each location, year, and age-sex group. For aetiology estimation, we used a counterfactual approach to quantify population-attributable fractions (PAFs). Additionally, we estimated the diarrhoeal disease burden attributable to the independent effects of risk factors using the comparative risk assessment framework. Findings In 2021, diarrhoeal diseases caused an estimated 1.17 million (95% uncertainty interval 0.793-1.62) deaths globally, representing a 60.3% (50.6-69.0) decrease since 1990 (2.93 million [2.31-3.73] deaths). The most pronounced decline was in children younger than 5 years, with a 79.2% (72.4-84.6) decrease in diarrhoeal deaths. Global YLLs also decreased substantially, from 186 million (147-221) in 1990 to 51.4 million (39.9-65.9) in 2021. In 2021, an esti

With the fast proliferation of intermittent renewable energy sources and fluctuations in load demand, power systems need to withstand an increasing number of disturbances that may affect the system frequency. In this paper, the highest acceptable penetration level of wind generation is formulated and calculated with and without considering operating reserve constraints as a function of equivalent governor response and system inertia. Afterward, the feasibility of wind turbine participation in the power system frequency regulation task is investigated and the minimum required wind turbine frequency response is calculated as a function of penetration level. This study uses a discretized model of dynamic system frequency response to estimate the minimum frequency after contingencies. To investigate the proposed methods, some sensitivity analyses are carried out on IEEE 39-bus test system. Simulations results illustrate a more secure and reliable operation of the power system when the wind turbines participate in the frequency regulation task.

In recent years, vision of distribution networks has been changed from passive to highly complex active network. This change results in some challenges in monitoring, control and protection systems that are based on situation awareness of the network conditions. To address these challenges, distribution state estimation (DSE) is a key element. State estimation in traditional distribution systems are largely based on substation measurements and pseudo-measurements (historical data). However, in active distribution network data from phasor measurement units (PMUs) can be used in a cost-effective manner for accurate system state estimation with significant reporting rate. In this paper, traditional linear voltage based SE algorithm (in rectangular form) has been extended in term of inclusion of PMUs for providing accurate estimation in the active distribution network. To evaluate the performance of the proposed voltage based DSE in the active distribution network, the generic 77 -bus UK distribution network has been simulated in Open DSS software, and its power flow results feed to MATLAB software environment. © 2018 IEEE.

This study compared the aroma-active compounds in 14 brands of commercially infant formula and investigated their changes during ambient storage after opening for 2 months. A total of 29 major aroma-active compounds were detected in infant formula. From the PCA and heatmap analysis, a total of 14 brands of infant formula were classified into 3 groups, the second group contained JLB-Y, AY and FH-F, of which 2-furanmethanol and (E,E)-3,5-octadien-2-one were mainly compounds, the third group contained YL and JLB-L, the characteristic flavor compounds in this group were mainly hexanal, heptanal, etc. Aldehydes, as the main volatile substances, account for more than half of the total volatiles. Nearly half of the aldehydes showed more significant changes after storage, e.g. hexanal, octanal, (E)-2-octenal and 3-methylbutyraldehyde. The YL and YP-Q produced more saturated aldehydes after storage, the concentration of hexanal in YL-2m and YP-Q-2m was 2138.5 μg/kg and 2004.1μg/kg, respectively. The concentrations of heptanal, octanal, and nonanal also increased relatively significantly, which may lead to a distinct rancid flavor in YL and YP-Q. Besides, among the ketones, (E,E)-3,5-octadien-2-one showed the greatest change after storage, especially in JLB-L. According to sensory evaluation experiments, the milky flavor of infant formulas decreased and fatty, rancid, fishy and grassy flavors were found to have increased to different extents after storage. The current information gap on the concentration and evolution of volatile compounds in commercially available infant formula is filled by this study.

Voltage unbalance and short circuits in distribution networks adversely affect the performance of grid-tied voltage source inverters (VSIs). Consequently, the dc-link voltage ripple may significantly increase leading to operation of VSI in an unsatisfactory manner. Conventionally in order to maintain the negative sequence current under unbalanced conditions, low-pass/trap filter in the current control loop are required which significantly reduce the controller bandwidth. In order to minimize the dc-link voltage ripple without impairing the controller bandwidth, this paper investigates the design and performance of Proportional-Integral-Resonant (PIR) controller in improving the performance of the VSI under unbalanced condition. The proposed design methodology is validated through simulations and experimental results.
