Author Affiliation: Department of Electrical Engineering, Indian Institute of Technology, Kanpur, India. Abstract: This letter presents a new method for the generation of reference voltage for a dynamic voltage restorer (DVR). These voltages, when injected in series with a distribution feeder by a voltage source inverter, can tightly regulate the voltage at the load terminal against imbalance o...

In this paper, we explore a new approach to abstract machines and optimal reduction through streams, ubiquitary objects in mathematics and computer science. We first define a sequential abstract machine capable of performing directed virtual reduction (DVR) and then we extend it to its parallel version, whose equivalence is explained through the properties of DVR itself. The result is a formal ...

The routing protocols in use today operate on implicit trust among the different routers. Specifically, the distance vector routing (DVR) protocols compute routing tables in a distributed manner, based on this implicit trust. This trust model however fails to ensure the factual correctness of the routing updates, which is very critical for secure routing. We propose a neighbor update propagatio...
