According to Moore’s law, technology scaling is continuously providing smaller and faster devices. These scaled devices are, however, becoming increasingly susceptible to in-field hardware failures from sources such as high-energy particle strikes (or soft-errors). This reliability threat is expected to affect a broad computing market motivating the need for very low cost resiliency solutions. ...

Solutions To Some Sastry Problems On Smarandache Number Related Triangles

In his recent paper[l], Sastry defines two triangles T(a,b,c) and T(a',b',c') to be Smarandache related ifS(a) = Sea'), S(b) = S(b') and S(c) = S(c'). The function S is known as the Smarandache function and is defmed in the following way. For n any integer greater than zero, the value of the Smarandache function Sen) is the smallest integer m such that n divides m!. He closes the paper by askin...

TPOT-RL Applied to Network Routing

Team-partitioned, opaque-transition reinforcement learning (TPOT-RL) is a distributed reinforcement learning technique that allows a team of independent agents to learn a collaborative task. TPOT-RL was first successfully applied to simulated robotic soccer (Stone & Veloso, 1999). This paper demonstrates that TPOT-RL is general enough to apply to a completely different domain, namely network pa...

An Introduction to Hybrid System Modeling Analysis and Control John Lygeros George Pappas and Shankar Sastry

Hybrid systems combine discrete event and continuous time dynamics and can serve as models of large scale systems We provide an overview of modeling analysis and controller synthesis techniques for hybrid systems A modeling language for describing a wide class of hybrid phenomena is rst presented and conditions for existence and uniqueness of executions are provided We then discuss analysis pro...
