7. Learning not to fear : extinction, erasure, and the recovery of fear memories
Sammanfattning : Much of the progress in understanding the mechanisms underlying the formation and persistence of fear memories comes from studies of Pavlovian conditioning and extinction. Recently, considerable interest has been turn to strategies that facilitate the development and persistence of extinction. LÄS MER
8. Distributed Coded Caching with Application to Content Delivery in Wireless Networks
Sammanfattning : The amount of content downloaded to mobile devices, mainly driven by the demand for video content, threatens to completely congest wireless networks and the trend of ever increasing video traffic is expected to continue unabated for many years. A promising solution to this problem is to store popular content closer to end users, effectively trading expensive bandwidth resources for affordable memory, a technique known as caching. LÄS MER
9. Investigations of Issues Relevant to the Application of Photon Echoes in Information Technology
Sammanfattning : Photon echoes have been studied both experimentally and theoretically, with the main part of the work centred around the concept of using photon echoes for all-optical data storage and processing. The four basic Boolean operators, AND, OR, NOT and XOR have been experimentally demonstrated using photon echoes. LÄS MER
10. Coding and Transmission Strategies for Secrecy
Sammanfattning : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model.
