OBJECTIVE To describe sociodemographic characteristics and analyze temporal trends in the mortality of motorcyclists injured in traffic accidents. METHODS This was a time-series study with data from 580 motorcyclist deaths in the Brazilian Federal District from 1996 to 2007. The data were obtained from the Mortality Information System. Mortality rates specific for age and sex, the standardize...

Despite the significant increase in mortality among older motorcyclists during the past decade, few studies have addressed specific injuries or mortality rates among all those injured. The purpose of this study is to describe the crash and injury characteristics among a cohort of motorcyclists injured in Maryland, and to determine the influence of age and crash type on mortality, injury pattern...

UNLABELLED This article presents the steps of transforming the material and organizational aspects in the work environment, beyond the social order for the proper development of activities in the Household Distribution Center, the Postmen Motorcyclists. The demand was made by managers from the accident records, establishing the need to identify the working conditions of postmen motorcyclists, r...

This paper introduces the Hocman prototype, which supports mobile interaction among motorcyclists. The design is based on findings from an ethnographic field study. Motorcyclists are a community with a strong social commitment. They use their bikes together, which allows for visual interaction. However, their extreme mobility creates problems in coming together. Recently the group studied have ...

introduction: motorcyclists play an important part in increasing the death toll form road accidents in study is designed to identify the risky behaviors experienced by the motorcyclists which is believed to help promote the safety of them and other members of the community. materials and methods: this was a qualitative study and we selected a sample of motorcyclists from different parts of tehr...

Due to the increasingly important role in monitoring and data collection that sensors play, accurate and timely fault detection is a key issue for wireless sensor networks (WSNs) in smart grids. This paper presents a novel distributed fault detection mechanism for WSNs based on credibility and cooperation. Firstly, a reasonable credibility model of a sensor is established to identify any suspic...

We introduce Hocman, a mobile HTTP peer-to-peer application, which supports social interaction among motorcyclists. The system enables sharing of multimedia content, such as HTML documents, audio clips and images over ad-hoc networks. The design derives from requirements found in an ethnographic fieldwork on motorcyclists. Our understanding of speed, the vast setting and collaborative activitie...

For failure prediction and information interaction problems of multi-equipment health management, fault prediction technology of multi-equipment and multi-parameter was proposed based on the system network. The state judgment and fault diagnosis algorithm is adopted by SOM self-organizing feature map neural network, the network parameters and node structure are changed adaptively, and the real-...
