OBJECTIVES Test the influence of darkness in the street robbery crime event alongside temperature. METHODS Negative binomial regression models tested darkness and temperature as predictors of street robbery. Units of analysis were four 6-hr time intervals in two U.K. study areas that have different levels of darkness and variations of temperature throughout the year. RESULTS Darkness is a k...

introduction: this study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the italian version of the nose scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction.     materials and methods: data was obtained from a total of 233 adult patients, (1...

Wireless sensor networks are gaining increasing attention in both industry and academia. One of the main issues that prevents the ubiquitous use of wireless sensor networks is that wireless sensors typically have limited energy supplies. Hence, it is of great importance to save energy and prolong the network lifetime while maintaining the application’s Quality of Service (QoS). For wireless sen...

Sensor sleeping is a widely-used and cost-effective technique to save energy in wireless sensor networks. Protocols at different stack levels can, either individually or simultaneously, make the sensor sleep so as to extend the application lifetime. To determine the best choice for sensor sleeping under different network conditions and application requirements, we investigate single layer and m...
