Lithium-ion (Li-ion) batteries are becoming increasingly popular as a reliable source of energy for portable electronic devices. Compared to alternative battery technologies Li-ion batteries provide one of the best energy-to-weight ratios, exhibit no memory effect, and have low self-discharge when not in use. These beneficial properties, as well as(More)
This paper provides a comprehensive review of battery management systems for grid-scale energy storage applications. ABSTRACT | The current electric grid is an inefficient system that wastes significant amounts of the electricity it produces because there is a disconnect between the amount of energy consumers require and the amount of energy produced from(More)
Lithium-ion batteries are an important technology to facilitate efficient energy storage and enable a shift from petroleum based energy to more environmentally benign sources. Such systems can be utilized most efficiently if good understanding of performance can be achieved for a range of operating conditions. Mathematical models can be useful to predict(More)

Carcinoma in situ (precancerous lesion) of true vocal cord in a nonsmoker adolescent female without any history of prior neck irradiation is rare. A 16-year-old female patient without any of the known risk factors presented with history of gradual-onset hoarseness of voice unrelieved by symptomatic treatments for 1 year. Contrast-enhanced CT scan of neck(More)
