Experimental study of the frequency limits of a resonant tunneling oscillator
Paul D. Coleman,Steven Goedeke,Thomas J. Shewchuk,Peter Chapin,Joseph M. Gering,Hadis Morkoç +5 more
TL;DR: In this article, an equivalent circuit for a resonant tunneling diode was proposed, which consists of a series of R and C in parallel with a nonlinear negative differential conductance −G, the combination in turn in series with a resistor r. The resistive cutoff frequency predicted by this model depends on both the RC and RG products.

Stable and unstable current‐voltage measurements of a resonant tunneling heterostructure oscillator
T. J. Shewchuk,Joseph M. Gering,Peter Chapin,Paul D. Coleman,W. Kopp,C. K. Peng,Hadis Morkoç +6 more
TL;DR: In this article, an approach is presented to obtain stable, dc currentvoltage (I•V) curves by using a damped microwave circuit to prevent device oscillations which distort the measured I•V curve.

Risk assessment in distributed authorization
Peter Chapin,Christian Skalka,X. Sean Wang +2 more
- 11 Nov 2005
TL;DR: A trust management logic that incorporates formal risk assessment is introduced, which allows risk levels to be associated with authorization elements, and promotes development of a distributed authorization algorithm allowing tolerable levels of risk to be precisely specified and rigorously enforced.

Risk management for distributed authorization
TL;DR: A trust management logic based on the system RT that incorporates formal risk assessment is introduced, which allows risk levels to be associated with authorization, and authorization risk thresholds to be precisely specified and enforced.
