Rechargeable batteries are essential for the increased demand energy storage technologies due to their ability adapt intermittent renewable energies into electric devices, such as vehicles. To boost battery performance, applying external fields assist electrochemical process has been developed and exhibits significant merits in efficiency cycle stability enhancement. This perspective focuses on...

Ambient intelligent systems continuously gain importance in a variety of application domains. Nowadays one of the most important ambient intelligence domains is assisted living, which involves devices and services supporting elderly people during their everyday life. Typical assisted living applications include health monitoring, remote nursing, and alarm systems. Model-driven design methodolog...

We present an OpenGL-assisted visibility culling algorithm to improve the rendering performance of large polygonal models. Using a combination of hierarchical model-space partitioning, OpenGL-assisted view-frustum culling, and OpenGL-assisted occlusion culling, we achieve a significantly better performance on general polygonal models than previous approaches. In contrast to these approaches, we...

We use stochastic geometry to analyze the performance of a partial decode-and-forward (PDF) relaying scheme applied in a user-assisted relaying setting, where an active user relays data through another idle user in uplink cellular communication. We present the geometric model of a network deploying user-assisted relaying and propose two geometric cooperation policies for fast and slow fading ch...

A n estimated 600 000 Americans are victims of sudden , unexpected out-of-hospital cardiac arrests each year. 1 Emergency medical services (EMS) providers attempt resuscitation in 360 000 of these " EMS-treated " individuals. EMS crews declare another 240 000 victims dead on arrival because the cardiac arrest was unwitnessed and the victim's body shows physical signs that death has not just occ...
