Large battery packs composed of Lithium-Ion cells are continuously gaining in importance due to their applications in Electric Vehicles (EVs) and smart energy grids. To ensure maximum lifetime, safety and performance of the battery pack, complex embedded system architectures consisting of sensors, power electronics and microcontrollers are integrated into the pack as Battery Management System (BMS).Active cell balancing is a recently developed method that reduces losses by reducing the hardware components and providing more software control.

In this paper, we prove coincidence and common fixed point theorems for two pair of multivalued and single valued mappings in complete partial metric spaces. These results improve, extend and generalize the corresponding results in the literature. Moreover, an example is provided to illustrate the usability of main results.

Background : To increase the country's energy production, the State of Niger has built a 7MW photovoltaic solar power plant connected on grid of the Nigerien electricity company in the department of Malbaza, Tahoua region (130 58'3.54 ”North and 5031'11.95 " East). Objective: In order to analyze the operation of this plant, a study of energy production was carried out in this article. Methods: The study was based on data on energy production as a function of irradiation and temperature from January 1, 2019 to December 31, 2019.

Introduction: The elderly population of the world increasing gradually. The situation of elderly population of Nepal also is in increasing trend as in other countries.

Background: Prevalence of cerebral palsy (CP) in developing country is high. It is one of the most common causes of childhood physical disability. Purpose: To establish a registry of CP in Kafrelsheikh Governorate except Kafrelsheikh city-Egypt. Subject and Methods: One hundred and three children with CP of both genders who were receiving physical therapy in Kafrelsheikh Governorate except Kafrelsheikh city participated in the study. Their ages ranged from one month to 18 years. They were subjected to confidential modified Australian Registry Form.

Background: The central venous accesses technique uses a direct visualization puncture. With the advent of the ultrasound (US)-guided puncture, a high variation rate in the anatomical position (AP) of the right internal jugular vein (RIJV) was observed compared to the right common carotid artery (RCCA). Objective: This study describes the rate of AP variability in RIJV, compared with previous studies and descriptions.

Coronavirus Disease 2019 (COVID-19), caused by a novel corona virus (SARS-CoV-2), is a highly contagious disease. Most of the infected patients have mild symptoms including fever, fatigue and cough. But in severe cases, patients can progress rapidly and develop to the acute respiratory distress syndrome, septic shock, metabolic acidosis and coagulopathy. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative agent of corona virus disease 2019 (COVID-19), which was declared a global pandemic by the World Health Organization on 11th March 2020.

Road traffic injuries (RTI) are worldwide health and constitute an oversized majority of the deaths caused by all injuries. Every year the lives of approximately 1.35 million people are died as a result of a road traffic crash. Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. we are introducing the automated alert device for vehicle accidents. The proposed system detects the accident and sends the data in less time to emergency services like 108 in India.
