1 Khan, Faisal HabibCommercial and industrial applications getting ready for direct-current power distributionThis paper describes design trends in several classes of power-electronic appliances that will increase the appeal for distributing dc power in buildings. In the commercial sector information technology (IT) power conversion architectures are moving from multi- to single-voltage supplies, initially...Direct current power distribution; Commercial applications2004-01-01
2 Harrison, Reid R.Fly like a flyTHIS FALL, several biologist colleagues of mine plan to build a movie theater for houseflies. In fact, it's a miniature IMAX theater-complete with a panoramic screen-inside of which they'll place a tiny rotating cage, a downsized version of the ones that astronauts use to simulate tumbling in spa...2005
3 Furse, Cynthia M.Statistical comparison of capacity predictions for realistic MIMO channelsThe impact of antenna polarization on channel capacity is explored in multiple-input, multiple-output (MIMO) systems. An idealized polarization model involving branch power rations (BPR's) and channel cross-coupling is incorporated into channel-specific capacity calculations. Results are compared f...2007-01-01
4 Simpson, Jamesina J.FDTD calculations of the diffraction coefficient of vibrating wedgesThe full-vector Maxwell's equations finite-difference time-domain (FDTD) method is employed to calculate diffraction coefficients of vibrating conducting and dielectric wedges. Two-dimensional FDTD models of right-angle wedges are constructed to include total-field scattered-field incident plane-wav...2011-01-01
5 Furse, Cynthia M.Leaky fields from damaged shieldsIn a world where wireless devices appear to dominate society, it is wires that truly rule and connect our lives. Certainly the spread of cellular phones, Bluetooth technology, wireless sensor networks, and advances of ion-lithium battery capabilities have made common daily devices more disconnecte...2011
6 Furse, Cynthia M.Reflectometry for structural health monitoringAging wiring and structural cables in buildings, aircraft and transportation systems, consumer products, industrial machinery, etc. are among the most significant potential causes of catastrophic failure and maintenance cost in these structures. Smart wire health monitoring can therefore have a subs...2011-01-01
7 Furse, Cynthia M.Feasibility of spread spectrum sensors for location of arcs on live wiresSpread spectrum methods are an important emerging class of sensors that have the potential to locate small, intermittent faults on energized aircraft power circuit wires. Previous work has demonstrated the use of these methods for hard faults (open and short circuits). This paper extends that work ...Spread spectrum sensors; Wire fault location; Live wires2005-12
8 Furse, Cynthia M.Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wiresThe length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective. Short-circuited ...Aging aircraft wire; Capacitance sensors; Fault detection; Inductance sensors2009-08
9 Furse, Cynthia M.Application of phase detection frequency domain reflectometry for locating faults in an F-18 flight control harnessThe performance of a phase-detection frequency-domain reflectometer (PD-FDR) for locating open and short circuits (hard faults) in a Navy F-18 flight control harness has been tested, and the analytical expressions for accuracy verified. Nine different types of aircraft wires appear in this harness:...Phase detection; Frequency domain reflectometry; PD-FDR; Wire fault location; Aging wire; Flight control harness2005-05
10 Furse, Cynthia M.Measurement and modeling of multiuser multiantenna system in aircraft in the presence of electromagnetic noise and interferenceThis paper evaluates the accuracy with which the performance of a multi-user multi-antenna system can be predicted with and without considering co-channel interference and noise (Gaussian, α- stable and Cauchy) using a site-specific 3D ray-tracing algorithm as well as with statistical models with G...2011-01-01
11 Furse, Cynthia M.Measurement and modeling of interference for multiple antenna systemThis paper provides a detailed signal model based on network theory to predict the multi-antenna capacity in the presence of co- and adjacent channel interference. This model expands on previous channel models by including the simultaneous effects of interference, antenna matching, efficiency, direc...2010-01-01
