Title of Document: THE DEVELOPMENT AND TESTING OF THREE TECHNIQUES FOR ATTACHING SOLAR-POWERED GSM SATELLITE TRANSMITTERS ON SURF SCOTERS Kevin M. McBride, Master of Science, 2014 Directed By: Dr. Mary Ann Ottinger, Department of Animal Sciences Implanted satellite transmitters are used in seaducks to track migration routes, breeding, and wintering grounds. However, high mortality rates, handli...

In multiple-input single-output (MISO) wireless power transfer (WPT) via magnetic resonant coupling (MRC), multiple transmitters are deployed to enhance the efficiency of power transfer to the electric load at a single receiver by jointly optimizing their source currents to constructively combine the induced magnetic fields at the receiver, known as magnetic beamforming. In practice, since the ...

The Brownie tag-recovery model is useful for estimating harvest rates but assumes all tagged individuals survive to the first hunting season; otherwise, mortality between time of tagging and the hunting season will cause the Brownie estimator to be negatively biased. Alternatively, fitting animals with radio transmitters can be used to accurately estimate harvest rate but may be more costly. We...

In this study, a reconfigurable power divider (RPD) enabled energy efficient direction modulation (DM) transmitter for orthogonal frequency division multiplexing (OFDM) modulated data transmission is proposed. The RPD can smartly select the output ports and operate as or switch with appropriate control conditions. Hence, able to recycle in ‘OFF’ state antennas, which otherwise wasted convention...

Since they appeared, wireless technologies have deeply transformed our society. Today, wireless internet access and other wireless applications demand increasingly more traffic. However, the continuous traffic increase can be unbearable and requires rethinking and redesigning the wireless technologies in many different aspects. Aiming to respond to the increasing needs of wireless traffic, we a...

The digestive tract is supplied by extrinsic and intrinsic sensory neurones that, together with endocrine and immune cells, form a surveillance network that is essential to gut function. This article focuses on the responses of extrinsic afferent neurones to chemical insults of the gastrointestinal mucosa and their pathophysiological relevance to mucosal integrity and abdominal pain. Within the...

Radio-telemetry is often used to track birds, and several investigators have examined the possible effects of radio-transmitters on birds. One approach to this question is to determine if transmitters induce physiological stress. Using hematological indicators of stress (heterophil-lymphocyte [H/L] ratios), studies of captive birds have revealed no evidence that radio-transmitters cause stress....
