Low Power Wake-Up Signaling For Dense Sensor Networks, Ahmed M. Abuseta Ammar Dec 2011

Low Power Wake-Up Signaling For Dense Sensor Networks, Ahmed M. Abuseta Ammar

Graduate Theses, Dissertations, and Problem Reports (ETD)

In wireless sensor networks, nodes are required to reduce their idle listening time in order to minimize energy consumption and increase their lifetime. The idle listening time is decreased by making the nodes remain in sleep mode and wake up only when they are required to sense or transmit information about an event. This strategy requires the source node to send a wake-up signal before it transmits data to the network. This wake-up signal requires energy and the objective of this work is to lower this signal's energy consumption.;In order to achieve this, this work uses Near Field Magnetic Induction …

Entertaining A False Reality: A Social Comparison Examination Of Beauty Pageant Participation And The Effect On Body Dissatisfaction, Depression, And Self-Esteem, Angela Everhart

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study investigated the effects of beauty pageant participation on body dissatisfaction, depression, and self-esteem among women. A group of 20 women who participated in reality show beauty pageants as adults was compared with another group of 20 women who had never participated in beauty pageants. Pageant participants scored higher on body dissatisfaction as well as self-esteem. Neither group had mean depression scores in the clinically significant range. These findings suggest that beauty pageant participation among young adult women may influence their body dissatisfaction and self-esteem but may not have a significant effect on depression.
