Creator:: Lewis, James M.
Abstract:: The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the L1 and L2 caches as well as main memory. The heavy load placed...
Resource Type:: Masters Thesis

Creator:: Gatimu, Kevin
Abstract:: Mobile devices are becoming more prevalent and complex. As a result, the wireless communication aspect of these devices is becoming increasingly signiﬁcant. At the same time, video demands in terms of availability and quality are also on the uprise. High deﬁnition (HD) video is the standard of choice for meeting...
Resource Type:: Masters Thesis

Creator:: Gatimu, Kevin
Abstract:: The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

Creator:: Johnson, Taylor N.
Abstract:: Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

Creator:: Khanna, Rahul, 1966-
Abstract:: Advances in low-power digital integration and microelectro-mechanical systems (MEMS) have paved the way for micro-sensors. These sensors are equipped with data processing capabilities along with sensory circuits. Sensor data are processed on these individual sensors and transmitted to the target (sink). Lowcost integration and small sizes of these sensors have...

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...
Resource Type:: Dissertation

Creator:: Gruss, Daniel S.
Abstract:: Time-dependent electronic transport is increasingly important to the state-of-the-art device design and fabrication. The development of nanoscale sensing, the harnessing and control of structural fluctuations, and the advancement of next-generation materials all require a treatment of quantum dynamics beyond the level of traditional methods and a more nuanced approach to...
