چکیده
must be profitable. But how profitable and how successful spam campaigns are has not been quantitatively measured. One reason that this has yet to have been studied is that designing a methodology for the inquiry into the strategies and success of spammers has presented a number of knotty problems for researchers. But in a bold move, CNS faculty researchers Geoffrey Voelker and Stefan Savage (pictured above, l-r) deduced that “the best way to measure spam is to be a spammer.” Savage and Voelker reported the first such analysis based on this daring technique in their recent paper presented at the 2008 ACM conference on Computer and Communication Security, “Spamalytics: An Empirical Analysis of Spam Marketing Conversion.”

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
متن کاملDesign of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملTechnologies and Foundations for Robust and Secure Networked Systems
Any piece of complex software can be expected to fail given the perfect combination of programming bugs, administrative errors, and unusual system demands. Though built to be robust and tested under a number of scenarios, not every parameter of input or use can be foreseen by programmers. However, the cost of software failures in the production mode can be ruinously high in terms of lost revenu...
متن کاملDevelopment of RMPC Algorithm for Compensation of Uncertain Time-Delay and Disturbance in NCS
In this paper, a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance. The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain time-delays and system disturbances. The continuous system with time-delay is discretized using uncertainty po...
متن کاملRobust Model for Networked Control System with Packet Loss
The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...
