This empirical analysis examines the use of the live-streaming application Periscope in three crises that occurred in 2015. Qualitative and quantitative analyses of tweets relating to the Amtrak derailment in Philadelphia, Baltimore protests after Freddie Grey’s death, and Hurricane Joaquin flooding in South Carolina reveal that this recently deployed application is being used by both citizens ...

In August 2007, several horses showed pyrexia and respiratory signs while in post-arrival quarantine in Australia. Subsequent investigations diagnosed equine influenza by serology and PCR in two quarantine stations. A common origin in a shipment of horses from Japan was indicated.

OBJECTIVE Introducing message prompts at the 'point-of-choice' (POC) between stairs and escalators increases stair choice in 'public-access' settings (e.g. malls). For nationwide campaigns, plentiful POCs appear needed. We audited the availability of POCs in public-access settings across England. METHODS Boundaries for 25 urban areas (population=6,829,874) were verified using Ordinance Survey...

this research presents and solves a new mathematical model for school bus routing problem (sbrp). sbrp is a specific case of vehicle routing problem (vrp). despite prevalent models, this model includes location and routing simultaneously. besides, the vehicles are non-homogenous. in addition, instead of locating schools which are the depots, we consider locating bus stops that are mentioned &ap...

With the expansion of E-mobility technology, demand for Medium-Voltage (MV) Electric Buses (E-buses) charging infrastructure has significantly increased. In this regard, effective connection E-bus chargers to a medium voltage power grid is essential provide fast and carry out multiple processes simultaneously. One main building blocks DC-DC converter stage responsible regulating flow matching d...

Social systems have recently attracted much attention, with attempts to understand social behavior with the aid of statistical mechanics applied to complex systems. Collective properties of such systems emerge from couplings between components, for example, individual persons, transportation nodes such as airports or subway stations, and administrative districts. Among various collective proper...

BACKGROUND With an increasing proportion of the population living in cities, mass transportation has been rapidly expanding to facilitate the demand, yet there is a concern that mass transit has the potential to result in excessive exposure to noise, and subsequently noise-induced hearing loss. METHODS Noise dosimetry was used to measure time-integrated noise levels in a representative sample...

Bus Rapid Transit (BRT) is a rapidly growing national trend in the provision of public transportation. At present, with more than 150 New Start Rail Projects currently in the FTA pipeline, a wide range of alternatives is necessary to fulfill the demand for cost-effective rapid public transportation. As a lower cost, high-capacity mode of public transportation, BRT can serve as an option to help...
