Rechargeable batteries are now widely used as the power supply source in many portable electronic equipments such as Laptops, cell phones and digital cameras. Charging circuits depend on the batterys chemistry and the most popular rechargeable batteries are Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), and Lithium-Ion (Li-Ion). This application report discusses the method to charge a Li-I...

In this paper we are proposing an efficient and novel architecture for dynamic invocation and discovery of web services in mobile. While we are handling with the mobile, we need to consider the resources of the mobile, these battery services are not flexible or optimal like desktops or laptops. We implemented a proxy between service and mobile client for dynamic invocation and discovery of serv...

The Bluetooth protocol is one of the better-known technologies in the field of pervasive computing and is now beginning to emerge in the consumer electronics marketplace in devices such as digital cameras, mobile phones and laptops. This paper examines the performance of the Bluetooth protocol using a simulator developed as part of the University of Berkeley’s Network Simulator (ns) [1]. In par...

This raises questions about how why people screens the viewing experiences they gain from doing so. To address questions, we draw 200 semi-structured interviews with film audience mem...

State-of-the-art software tools for neuronal network simulations scale to the largest computing systems available today and enable investigations of large-scale networks of up to 10 % of the human cortex at a resolution of individual neurons and synapses. Due to an upper limit on the number of incoming connections of a single neuron, network connectivity becomes extremely sparse at this scale. ...
