Batteries are one of the most important components in many mechatronics systems, as they supply power to the systems and their failures may lead to reduced performance or even catastrophic results. Therefore, the prediction analysis of remaining useful life (RUL) of batteries is very important. This paper develops a quantitative approach for battery RUL prediction using an adaptive bathtub-shap...

the effects of thiamine, ascorbic acid ami their combination an workers who are continuously exposal to lead has been investigated. in this study 60 persons in a battery industry was selected and divided into four equal groups. group i received placebo, group ii thiamine (300 mg), group iii ascorbic acid (250 mg) anil group iv thiamine (300 mg) plus ascorbic acid (250 mg) three times a day (ora...

OBJECTIVE To evaluate lead exposure among lead-acid battery workers in Korea, to evaluate in more detail the erythrocyte pyrimidine 5'-nucleotidase (P5N) test for lead exposure, and to evaluate the abnormal accumulation of erythrocyte pyrimidine nucleotides in the battery workers. METHODS Activity of P5N and other biological variables were examined in 66 exposed workers in a lead-acid battery...

Solar energy, despite being inexhaustible, has a major shortcoming; it is intermittent. As a result, there’s a need for it to be stored for later use. The widely used energy storage in photovoltaic system applications is the leadacid battery and the knowledge of its state-of-charge (SOC) is important in effecting efficient control and energy management. However, SOC cannot be measured while the...

An environmental and biological monitoring of a lead acid battery manufacturing unit was carried out to measure the respirable particulate matter, lead content in working atmosphere and blood lead levels of workers employed in different sections. The results showed high mean air lead concentration in buffing (1444.45 microg/m(3)), plate cutting (430.14 microg/m(3)) and pasting (277.48 microg/m(...
