Evolutionary Approach to Efficient Provisioning and Self-organization in Wireless Sensor Networks (WSN)

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...

Identifying and Removing On-chip Network Bottleneck in Throughput Processors

Creator:: Li, Yunfan
Abstract:: The high level of parallelism in throughput processors such as GPGPUs has resulted in significantly changed on-chip data traffic behaviors. This demands new research to identify and address the limiting factors of networks-on-chip (NoCs) in the context of throughput processors. In this work, we ﬁrst quantitatively analyze the performance of...

Investigation of bipolar resistive switching in zinc-tin-oxide for resistive random access memory

Creator:: Murali, Santosh
Abstract:: Resistive random access memory (RRAM) is a non-volatile memory technology based on resistive switching in a dielectric or semiconductor sandwiched between two different metals. Also known as memristors, these devices are potential candidates for a next-generation replacement for flash memory. In this thesis, bipolar resistive switching is reported for the...
