The Laser Interferometer Gravitational wave Observatory (LIGO) is a network of first generation interferometric detectors aiming to make the first direct observations of gravitational waves. Progress in the commissioning of the detectors has brought them within a factor of two of their design sensitivity near 150Hz during the most recent science run of the instruments in March of 2005. Further ...

Recent measurements highlight the importance of batteryaware evaluation of energy efficiency in wireless sensor networks. However, existing battery models been not investigated in the context of the low duty cycle, short duration loads that are typical of sensor networks. We evaluate three battery models with regard to their applicability in the WSN context. Our evaluation focuses on how the mo...

In this work, molecular dynamics (MD) simulations were employed to investigate the effects of duty cycle changes and utilization of tantalum nitride interlayer on the surface roughness and adhesion of Ta coating deposited by pulsed-DC plasma assisted chemical vapor deposition. To examine the simulation results, some selected deposition conditions were experimentally implemented and characterize...

In the paper, we propose an energyefficient communication protocol, called Scheduling-based Low duty cycle Energy Efficient Protocol (SLEEP). The proposed protocol ensures that a node wakes up at specific times and transmits only when the receiving node is awake to receive a message, while ensuring that the channel capacity is fairly distributed among participating nodes. The protocol is simple...

Coexistence of Wi-Fi and LTE in unlicensed spectrum (LTE-U) is recently drawing significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices transmit their signals only in predetermined duty ...

The Wireless Body Sensor Network (WBSN) is an incredible developing data transmission network for modern day communication especially in Biosensor device networks. Due to energy consumption biomedical transfer have impacts of sink nodes get loss information on each duty cycle because Traffic interruptions. reason behind the popularity WBSN characteristics contains number sensor transmit various...
