background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

This paper focuses on the impact of rainfall on the temporal and spatial distribution of taxi passengers. The main objective is to provide guidance for taxi scheduling on rainy days. To this end, we take the occupied and empty states of taxis as units of analysis. By matching a taxi's GPS data to its taximeter data, we can obtain the taxi's operational time and the taxi driver's income from eve...

In the study of taxi subsidy scheme for "ease taxi difficult" issue,from the driver’s angle,regard income levels, soliciting risk,self-selection, technical level these evaluation factors as an evaluation index.Fuzzy comprehensive evaluation model based on the law of entropy,analyze the date of drivers’ satisfaction before and after the taxi subsidy scheme,the conclusion of the implemented of th...

Several epidemiological studies have shown that the prevalence of ischemic heart disease is higher in occupational drivers than in people with other occupations. Although occupation categories can be surrogate measures for coronary risk factors, the relationships between taxi driving and severity of coronary heart disease (CHD) has not been investigated. Even more important, the contribution of...

Airport surface congestion results in significant increases in taxi times, fuel burn and emissions at major airports. This paper describes the field tests of a congestion control strategy at Boston Logan International Airport. The approach determines a suggested rate to meter pushbacks from the gate, in order to prevent the airport surface from entering congested states and to reduce the time t...

Every week I hear people complain about meetings. Here’s something to consider: What would happen to your organization if it became difficult to have face-to-face meetings? Some organizations have taken steps in this direction by holding meetings in rooms without chairs, imposing short time limits, or limiting the size of the groups. But what if an organization went further and penalized people...

Taxi is a flexible way of transportation; however, with the fast growth of urban areas, the task of finding new passenger quickly becomes a challenging task for taxi drivers. In this work, we propose a recommendation system to assist taxi drivers searching for the next pick-up. With an inference engine based on a naïve Bayesian classifier, we analyze taxi-GPS traces collected in Lisbon, Portuga...

Taxi service is an important mode of modern public transportation. However, operated by a large number of selfcontrolled and profit-driven taxi drivers, taxi systems are quite in efficient and difficult to analyze and regulate. While there has been some work on designing algorithms for improving taxi system efficiency, the state of the art algorithm, unfortunately, cannot scale up efficiently. ...

The Triticum aestivum L. endoxylanase inhibitor (TAXI) discovered by Debyser and Delcour [(1997) Eur. Pat. filed April 1997, published as WO 98/49278] and Debyser, Derdelinckx and Delcour [(1997) J. Am. Soc. Brew. Chem. 55, 153-156] seems to be a mixture of two different endoxylanase inhibitors, called TAXI I and TAXI II. By using Aspergillus niger as well as Bacillus subtilis endoxylanases for...

Electrification of transportation is critical for a lowcarbon society. In particular, public vehicles (e.g., taxis) provide a crucial opportunity for electrification. Despite the benefits of eco-friendliness and energy efficiency, adoption of electric taxis faces several obstacles, including constrained driving range, long recharging duration, limited charging stations and low gas price, all of...
