Using Software-Defined Networking And Openflow Switching To Reroute Network Traffic Dynamically Based On Traffic Volume Measurements, Ihab Al Shaikhli Jan 2019

Using Software-Defined Networking And Openflow Switching To Reroute Network Traffic Dynamically Based On Traffic Volume Measurements, Ihab Al Shaikhli

Master's Theses

Traditional switching and routing have been very effective for network packet delivery but does create some constraints. for example, all packets from a given source to a given destination must always take the same path. Within a traditional Ethernet network, a tree topology must be used. Software-Defined Networking (SDN) has the potential to bypass this tree-topology limitation by placing the control of the switches and their forwarding tables under a central device called a controller. SDN also allows for sets of controllers. the controller can identify individual network flows and issue commands to the switches to, in effect, assign individual …


Opioid Misuse Detection In Hospitalized Patients Using Convolutional Neural Networks, Brihat Sharma Jan 2019

Opioid Misuse Detection In Hospitalized Patients Using Convolutional Neural Networks, Brihat Sharma

Master's Theses

Opioid misuse is a major public health problem in the world. In 2016, 11.3 million people were reported to misuse opioids in the US only. Opioid-related inpatient and emergency department visits have increased by 64 percent and the rate of opioid-related visits has nearly doubled between 2009 and 2014. It is thus critical for healthcare systems to detect opioid misuse cases. Patients hospitalized for consequences of their opioid misuse present an opportunity for intervention but better screening and surveillance methods are needed to guide providers. The current screening methods with self-report questionnaire data are time-consuming and difficult to perform in …
