A new bus scheduling algorithm, developed by a University of Southern California engineer, aims to reduce waiting times and improve transit reliability. The algorithm analyzes the impact of slack time on buses and finds that building in between 15 and 20 percent slack time is optimal, depending on total round trip travel time.
A comprehensive study by University of Texas researchers reveals 237 complex motivations for human sex, including physical, emotional, and insecurity-based factors. The findings challenge common assumptions about the simplicity of human sexuality.
The University of Georgia has received a $1.9 million grant to educate consumers about natural gas usage and billing practices. Ten UGA Extension agents will provide face-to-face guidance on safety practices, gas maintenance, and preventing unnecessary disconnections.
Researchers develop novel nanoscale architectures using spin-wave buses for efficient interconnectivity and low power consumption. The breakthrough enables the design of fully interconnected networks of processors on a single chip, overcoming current limitations in spintronic architectures.
Researchers develop wireless public transport network protocol allowing vehicles to create a communication network. The system can learn from user behavior and adapt to traffic conditions, providing a more attractive option for commuters.
A study by UCLA found that children on school buses are exposed to high levels of diesel pollution, comparable to urban areas. The researchers analyzed six buses and found that intake fraction values were significantly higher than typical U.S. urban areas.
A new UC study reveals that children inside school buses inhale significantly more exhaust pollutants than those outside, particularly among older buses. The researchers found that for every metric ton of pollution emitted by a school bus, kids on that bus inhale comparable or larger amounts of pollution.
A study by Professor Michael Waterson found that fast food chains like McDonald's and Burger King locate closely together in shopping districts due to competition. The larger the population area, the sooner a McDonald's outlet opens, but this effect diminishes as population increases.
Researchers at Georgia Institute of Technology have developed a solution to stop noisy brakes once and for all. The new system uses a simple piezoceramic actuator to apply bursts of a 'dithering' frequency, suppressing vibrations that cause squeal.
The study found that conventional diesel buses produce nitrogen oxide pollutants contributing to photochemical smog and fine soot particles. Laser sensors measured pollutant levels in exhaust plumes from different bus types, revealing varying pollution problems.
A year-long evaluation of hybrid buses in NYC's fleet found a 10% higher in-service fuel economy and 36% lower oxides of nitrogen emissions. However, maintenance costs were significantly higher due to the maturity level of the technology, but are expected to decrease as it advances.
A meta-analysis of three studies found that low-intensity ultrasound therapy significantly reduces healing time for non-operative fractures. The treatment group showed a mean time to healing that was 6.41 times shorter than the control groups.
Johns Hopkins engineering undergraduates develop a restraining bar system that could reduce school bus injuries by protecting children without seat belts. The device features a pivoting bar with a manual-release lever, designed to keep children secure during head-on collisions or rollover accidents.
