Data Bandwidth Reduction Techniques For Distributed Embedded Simulatio
… benefits were quantified in terms of the bandwidth reduction ratio BR=N/I obtained from the comparison of the OneSAF Testbed Semi-Automated Forces (OTBSAF) simulator under DIS requiring a total of N bits and a testbed modified for the Concurrent Model approach which required I bits. In the …

A two-dimensional finite element mesh generator with automatic transitioning capability
… transition from low to high density areas. A bandwidth reduction routine is included to renumber the generated nodes most efficiently. An output file is created of node, element, and nodal load definitions which is organized for input to a finite element program.

Impact of ground plane serrations on radiation and impedance characteristics of a slot antenna over a conductive back plane
… is applied to a thin slot or dipole antenna, the bandwidth is significantly reduced. In the case of the slot antenna, this bandwidth reduction is due in part to reactive energy stored in parallel plate modes. The stored energy can be reduced by treating the edge of the ground plane with …

Image Chipping with a Common Architecture for Microsensors (CAuS)
… extend the system's lifespan, communication bandwidths are often limited. In order to reduce the required bandwidth, much of the signal processing necessary to achieve a desired functionality must be performed within the microsensor platform itself. This thesis effort provides this crucial …

Time-Offset Fractional-N PLLs for Heterodyne FMCW SAR
… assessed, namely: time domain zeroing, PLL loop bandwidth reduction, and a novel method termed range-Doppler spur masking. A subset of these suppression techniques were applied to measured SAR data sets, including car-borne data measured in Iowa, USA and airborne data captured in Oudtshoorn, …

Elimination of Edge Effects Using Spline Wavelets Which Maintain a Uniform Two-Scale Relation
… method of decomposition results in significant bandwidth reduction on solving an associated linear systems. Image distortion is reduced by employing natural spline projection. Finally, a hybrid projection scheme is proposed, which particularly for large systems further lowers operation count. …

Low-power and application-specific SRAM design for energy-efficient motion estimation
… algorithms provide 4.3x area, 56x on-chip bandwidth and 151 x off-chip bandwidth reduction. Second, a highly-parallel motion estimation design targeting ultra-low voltage operation and supporting AVC/H.264 and VC-1 standards are considered. Hardware reconfigurability along with frame and …

Development of high-speed vertical-cavity surface-emitting diode laser and vertical-cavity transistor laser for shortreach optical interconnects
… °C are included. The device demonstrates 30 GHz bandwidth at RT and over 20 GHz at 115 °C. The bandwidth reduction is attributed to the increased carrier recombination and photon lifetime at higher temperature. Bit error ratio (BER) measurements are used to correlate data rate with device optical …

QoS provisioning in multimedia streaming
… traffic, though usually compressed/encoded for bandwidth reduction, still consumes most of the bandwidth. In addition, compressed video streams typically exhibit highly variable bit rates as well as long range dependence properties, thus exacerbating the challenge in meeting the stringent QoS …

Finding regions of interest while video conferencing in bandwidth constrained environment
… however many of them suffer from low bandwidth availability. Since, video conferencing is a network intensive application, it is not always possible to maintain the level of user satisfaction when the available network bandwidth is low. In such situations, the large video frames do not …
