Preventing layer-3 wormhole attacks in ad hoc networks with multipath DSR
… when the multipath Dynamic Source Routing (DSR) protocol is used and finds suspicious behavior related to such attacks. It does not require any major protocol modification, nor as much cryptographic processing as the solutions previously proposed.

Quantifying the expression of dissimilatory sulfite reductase as a metric for sulfate reduction rates
… expression of dissimilatory sulfite reductase (dsr mRNA), a critical enzyme in the sulfate reduction pathway, can serve as an indicator of the rate of sulfate reduction in natural systems. We grew Desulfovibrio vulgaris in fed-batch reactors under electron-donor limiting conditions. To simulate …

Control Applications and Economic Evaluations of Distributed Series Reactors in Unbalanced Electrical Transmission Systems
… transmission lines. Distributed Series Reactor (DSR) control is a new smart grid technology that can be applied to control flows in the transmission system. DSRs can be used to balance phase flows in a single line as well as to control the distribution of flow in parallel flow paths. This …

A fast non-dominated sorting guided genetic algorithm for multi-objective power distribution system reconfiguration problem
… Distribution system reconfiguration (DSR) determines the status of both sectionalizing switches (which are normally closed) and tie switches (which are normally open). DSR has great benefits in both normal and abnormal operations (outages). DSR is a multi-objective, non-linear problem. …

EXPLORING THE MASTER CURVE PARAMETERS FOR EFFICIENT PERFORMANCE GRADING OF ASPHALT BINDERS FROM THE UNITED STATES OF AMERICA
… This study utilized Dynamic Shear Rheometer (DSR) testing to obtain rheological indicators such as Tδ=30°, Tδ=45°, Intermediate Temperature Performance Grade (ITPG), and master curve parameters under slow and fast cooling rates. Significant correlations between DSR indicators at different …

Enhancing Competitive Intelligence Using Geospatial Analysis and Social-Media Corpora
… research paper uses the design-science-research (DSR) approach to design and build the proposed artifact. From DSR lens, the artifact is evaluated using a mixed-method to examine the constructed artifact. Findings indicated participants had positive reactions to system usability, user experience, …

Sources of Nest Failure in Mississippi Sandhill Cranes, Grus canadensis pulla: Nest Survival Modeling and Predator Occupancy
… and egg inviability. Mean daily survival rate (DSR) was 0.72. The best approximating models included covariates for season date, temperature and nest age. DSR decreased with increasing season date, increasing nest age, and decreasing temperature. Hypotheses related to effects of renesting, human …
