This paper describes the Multi-Radio Diversity (MRD) wireless system, which uses path diversity to improve loss resilience in wireless local area networks (WLANs). MRD coordinates wireless receptions among multiple radios to improve loss resilience in the face of path-dependent frame corruption over the radio. MRD incorporates two techniques to recover from bit errors and lower the loss rates o...

In this paper we consider a complex supply chain system where facilities produce intermediate-items or enditems that are shipped to other facilities or customers. We consider a complicated production process that can be convergent, divergent and circulatory. In order to facilitate modeling and solving the integrated production-distribution planning problem in the supply chain, extended state ta...

We study the exploitation of polarimetric diversity in passive multistatic radar for detecting moving targets. We first derive a data model that takes into account polarization and anisotropy of targets inherent in multistatic configurations. Unlike conventional isotropic models in which targets are modeled as a collection of uniform spheres, we model targets as a collection of dipole antennas ...

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier block modulation scheme suitable for wireless communications. It is primarily used in high bit rate systems to mitigate inter-symbol interference (ISI) caused due to delay spread. While the ISI caused by delay spread is an annoyance factor, it also provides multipath diversity advantage if the path gains fade independently. Fo...

The interactions between predator diversity and primary consumer abundance can include direct effects and indirect, cascading effects. Understanding these effects on immature Anopheles mosquitoes is important in sub-Saharan Africa, where most cases of malaria occur. Aquatic predators and immature mosquitoes were collected from shallow pools of varying age previously excavated by brickmakers in ...

Providing reliable video communications over wireless ad-hoc networks is becoming increasingly important as these networks become widely employed in military, homeland defense security, and disaster recovery applications. However, wireless ad-hoc networks have a dynamically changing topology that can cause failures of links and nodes, thus resulting in path loss. Additionally, video communicati...

We apply a fully opportunistic relay selection scheme to study cooperative diversity in a semianalytical manner. In our framework, idle Mobile Stations (MSs) are capable of being used as Relay Stations (RSs) and no relaying is required if the direct path is strong. Our relay selection scheme is fully selection based: either the direct path or one of the relaying paths is selected. Macro diversi...

This paper describes an approach for half-duplex cooperative transmission to achieve cooperative diversity in a classical three-node relay channel. Assuming availability of channel state information at the source and relay, the approach makes use of this information to optimize distinct flows through the direct link from the source to the destination and the path via the relay, respectively. It...

Background & Aim: German chamomile is one of the most important medicinal plants. So, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. Determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of German chamomile (Matricaria chamomilla L.) populations...
