The use of mobile devices is often limited by the capacity of the employed batteries. The battery lifetime determines how long one can use a device. Battery modeling can help to predict, and possibly extend this lifetime. Many different battery models have been developed over the years. However, with these models one can only compute lifetimes for specific discharge profiles, and not for worklo...

It is necessary to form an energy system in order to deliver the electrical power to a region that delivering energy to them from the national grid is not possible. At the moment, using the hybrid renewable energy systems (HRES) is the suggestion of more articles and scientific books because of environmental problems, nearing to the end of fossil fuels, and challenges including unpredictability...

Electrochemical energy storage systems are categorized into different types, according to their mechanisms, including capacitors, supercapacitors, batteries and fuel cells. All battery systems include some main components: anode, cathode, an aqueous/non-aqueous electrolyte and a membrane that separates anode and cathode while being permeable to ions. Being one of the key parts of any new electr...

STUDY DESIGN A cross-sectional study design was used. OBJECTIVE The objective was to examine the influences of body anthropometrics, axial disc area, and lifting strength on disc degeneration and to compare these with the effects of lifetime physical demands and age. SUMMARY OF BACKGROUND DATA Although recent studies have shown that heredity is a dominant factor in disc degeneration, the co...

If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would have significant impact on the design, implementation and integration of energy storage devices. Here, we establish a paradigm change in battery assembly by fabricating rechargea...

Dedicated To my wife, Dohee Kwon v Acknowledgement First of all, I would like to express my deep gratitude to my advisor, Dr. Arumugam Manthiram, for having guided me to finish my research successfully and provided me precious support and constant encouragement. Without his support, it would have taken much longer to finish my work.

Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...
