Most law firms are struggling when it comes to diversity and inclusion. There fewer women in compared men. The majority of lawyers—81%—are White, despite White people making up only about 65% the school population. Lawyers color remain underrepresented with historic high being 28.32%. By comparison, 13.4% United States population is Black 5.9% Asian. biases that perpetuate this lack begin durin...
Attributed scattering feature models have shown potential in aiding automatic target recognition and scene visualization from radar scattering measurements. Attributed scattering features capture physical scattering geometry, including the non-isotropic response of target scattering over wide angles, that is not discerned from traditional point scatter models. In this paper, we study the identi...
Mobile communication platforms of ships, aircrafts, ground vehicles, or individual agents of both military and public services often operate in highly dynamic conditions with constantly changing infrastructure and access to communication resources. Efficient techniques for rapid and yet stable communication of such fleets with their control centres and between cooperating vehicles within the fl...
Similar to direct sequence code division multiple access (DS-CDMA), site diversity can be applied to a multicarrier-CDMA (MCCDMA) cellular system to improve the bit error rate (BER) performance for a user with weak received signal power, thus resulting in an increased link capacity. In this paper, the downlink site diversity reception using frequency-domain equalization based on minimum mean sq...
Synthesis of shape morphing compliant mechanism is inherently different from typical single output problems, due to the multiple output points along the morphing boundary. Two synthesis approaches, using a fixed initial discretization mesh and using a load path representation, have been developed previously to simultaneously address the topology, size, and geometry aspects of a compliant mechan...
It is well known that the third generation partnership project (3GPP) for WCDMA FDD has chosen Space Time Transmit Diversity (STTD) (known also as open loop transmit diversity) and Feedback Mode Transmit Diversity (FBTD) (known also as closed loop transmit diversity) as transmit diversity techniques for two transmit antennas. In this paper, we look into the performance of closed loop transmit d...
In recent years the Internet has grown to a very large and complex system. Covering all continents and an ever increasing number of users, the Internet consists of many important subjects to study. One such subject is the Border Gateway Protocol which assists in routing traffic from one source in the network to another destination in the network. However, previous studies have not focused on ho...
Multihoming, the practice of connecting to multiple providers, is becoming highly popular. Due to the growth of the BGP routing tables in the Internet, the way to multihome in IPv6 is required to preserve the scalability of the interdomain routing system. A proposed method is to assign multiple provider-dependent aggregatable (PA) IPv6 prefixes to each site, instead of a single provider-indepen...
Wireless sensor networks are composed by a high number of very simple nodes. A paradigm for the nodes transceiver technology is to be energy aware and cost conscious. In this paper we consider a nonlinear transceiver structure which is a key technology for low-cost and power efficient network nodes. We use a phase detection receiver with a branch dependent metric which benefits from the knowled...
