Winter road maintenance practitioners have expressed a strong interest in obtaining weather and road condition forecasts and treatment recommendations specific to winter road maintenance routes. These user needs led the Federal Highway Administration (FHWA) Office of Transportation Operations Road Weather Management Program to support the development of a prototype winter road Maintenance Decis...

Abstract – Free Space Optical (FSO) communication technology becomes a promising solution for the future optical broadband networks. This work is focused to carry out the investigation of the performance of Orthogonal Frequency Division Multiplexing (OFDM) FSO system using Optical Single Sideband (OSSB), Optical Double Sideband (ODSB) and Optical Vestigial Sideband (OVSB) modulation scheme by e...

Relationships between yearly malaria incidence and (1) climate data from weather station and (2) satellite-based vegetation health (VH) indices were investigated for prediction of malaria vector activities in Bangladesh. Correlation analysis of percent of malaria cases with Advanced Very High Resolution Radiometer- (AVHRR-) based VH indices represented by the vegetation condition index (VCI-moi...

Ground transportation of pigs at early ages is typical in modern swine production because the young animals are often produced in one part of the country and finished in another. One challenge associated with this practice is the profit-stripping incidence of mortality and compromised animal welfare due to stress stemming from unfavorable transporting conditions. The objective of this study was...

A human-in-the-loop simulation was conducted to evaluate a concept for introducing multi-sector trajectory planning operations into en route air traffic facilities in the NextGen Mid-Term timeframe. Multi-sector planning tools and procedures for local area traffic flow management were developed, and then tested using two different service provider team configurations. In one condition, local ar...

Thermal building simulation currently uses Typical Meteorological Year (TMY) data to guide the design decision-making process or for compliance with energy standards. TMY data usually excludes extremes and in many cases are gathered from microclimatic contexts that are not sufficiently representative of the project sites (e.g., airports), adding uncertainty in the analyses. To enable a quantifi...

As weather deteriorates, breeding animals have a diverse array of options to ensure survival. Because of their mobility, birds can easily abandon territories to seek out benign conditions away from the breeding site. The timing of abandonment, however, may have repercussions for territory size, mate quality, reproductive success, and survival. There is a large body of evidence indicating that t...
