Abstract With the development of urbanization, problem urban traffic congestion is becoming more and serious. An improved k-means clustering algorithm was proposed to solve that traditional center could easily be affected by fall into local optimal solution. Based on big data New York City taxis, operational characteristics are analyzed. The experimental results show K-means has a better analys...

Migration is a hallmark life history strategy of a diverse range of organisms, and also ubiquitous in ontogenic processes including normal embryonic development as well as tumor progression. In such scenarios, individual organisms/cells typically respond to long range (and often noisy) environmental cues. In addition, individuals may interact socially with one another leading to emergent group-...

background and aim: carbon monoxide is colorless and odorless gas. in high concentrations, co is deadly poisonous and in low concentrations can cause fatigue, headache, dizziness and seizures. carbon monoxide has a high affinity to combines hemoglobin which can decrease oxygen capacity in blood. to address this problem, human body begins to produce red blood cells, this can increases blood visc...

Short distance trips are crucial for urban mobility and accessibility. They can contribute to integrated transportation (the “last mile” problem), and more generally to urban ad-hoc ride sharing scenarios [1]. Since no transport provider covers short distance trips where demand arises, private car use is flourishing in recent decades, with all the known disadvantages of traffic congestions, res...

We have developed a novel method, (ECIS/taxis), for monitoring cell movement in response to chemotactic and chemokinetic factors. In this system, cells migrate in an under-agarose environment, and their positions are monitored using the electric cell-substrate impedance sensor technology to measure the impedance change at a target electrode, that is lithographed onto the substrate, as the cells...

A escala global el incremento masivo de vehículos motorizados, se ha convertido en una las primordiales amenazas para la salud pública, no son escasas ciudades donde los accidentes tráfico vigorizan esta problemática como un tema social crítico. Con objetivo proponer plan educación y prevención accidentabilidad conductores taxis, realizó estudio descriptivo cooperativa taxis San Francisco Milag...

This research focuses on utilizing typically overlooked taxi manifest data to analyze taxi operations with respect to transit, and also presents alternative uses for the data in transportation planning. Taxi travel characteristics are explored for Arlington, Virginia, a county containing both urban and suburban qualities. Previous research contends that manifest data can provide valuable quanti...
