Characterisation of RF propagation in metal pipes for passive RFID systems (2008)
Darmindra D. Arumugam*and, Daniel W. Engels
Abstract: In this paper we extend the theory of Radio Frequency (RF) propagation as it relates to propagation within metal circular pipes. This work is motivated by a need to understand the operation...
Abstract Parallel Processor Scheduling with Delay Constraints (2008)
Daniel W. Engels, Jon Feldman, David R. Karger, Matthias Ruhl
We consider the problem of scheduling unit-length jobs on identical parallel machines such that the makespan of the resulting schedule is minimized. Precedence constraints impose a partial order on...

Techniques for scheduling with rejection (1998)
Daniel W. Engels, David R. Karger, Stavros G. Kolliopoulos, R. N. Uma, Joel Wein
Abstract. We consider the general problem of scheduling a set of jobs where we may choose not to schedule certain jobs, and thereby incur a penalty for each rejected job. More specifically, we focus...
