Simulation of Exothermic and Insulated Materials Effect on Increasing Efficiency of feeder in Gray Cast Iron
, M.Sc. Thesis Sharif University of Technology ; Davami, Parviz (Supervisor) ; Varahram, Naser (Supervisor)
Abstract
The use of exothermic and insulated materials is one of the most effective methods in increasing feed efficiency. In order to model performance of these materials, we need for information in connection with thermo physical properties, interface resistances and way for releasing heat in exothermic and insulated materials. Due to lack of published information in this area, the purpose of this study is for increasing information in this area and especially in the heat release in these materials. In this investigation first, physical model governing this phenomenon was found. At this stage in order to Model of heat transfer from one dimensional transient heat conduction equation, discreted by...
Intrusion Detection in Data Networks Using Header Space Analysis
, M.Sc. Thesis Sharif University of Technology ; Pakravan, Mohammad Reza (Supervisor) ; Kazemian, Payman (Supervisor)
Abstract
Software Defined Networking (SDN) provides a logically centralized view of the state of the network, and as a result opens up new ways to manage and monitor networks. In this dissertation a novel approach to network intrusion detection in SDNs is introduced that takes advantage of these attributes. This approach can detect compromised routers that produce faulty messages, copy or steal traffic or maliciously drop certain types of packets. To identify these attacks and the affected switches, we correlate the forwarding state of network---i.e. installed forwarding rules---with the forwarding status of packets---i.e. the actual route packets take in the network and detect anomaly in routes....
