Key management is the base of wireless sensor network security, key pre-distribution way is a high feasibility method in key management. The network connectivity rate, resilience against node capture and the storage consumption are important performance indicators in key pre-distribution way. However, most of the existing key pre-distribution schemes of wireless sensor network have the problems...

Electric vehicles are one of the most complicated electric devices to simulate due to the significant number of different processes involved in electrical structure of it. There are concurrent processes of energy consumption and generation with different onboard systems, which make simulation tasks more complicated to perform. More accurate simulation on energy consumption can provide a better ...

Accounting for the CPU consumption of applications is crucial for software development to detect and remove performance bottlenecks (profiling) and to evaluate the performance of algorithms (benchmarking). Moreover, extensible middleware may exploit resource consumption information in order to detect a resource overuse of client components (detection of denial-of-service attacks) or to charge c...

A cross-sectional population-based study was carried out among individuals aged 20 to 69 years in the urban area of Pelotas, Rio Grande do Sul, Brazil. The objective was to analyze characteristics of hypertensive patients in relation to management of arterial hypertension. Among the 1,968 interviewees, 380 were hypertensive (19.3%), and 44.1% of these always consulted the same physician. Of the...

Accurate prediction of the future electricity consumption is crucial for production electricity management. Since the storage of electrical energy is very difficult, reliable and accurate prediction of power consumption is important. Different approaches for this purpose were used. In this paper, Grey model (1,1) based on grey system theory has been used for forecasting results. Annual electric...

BACKGROUND Excessive alcohol consumption is responsible for considerable harm from chronic disease and injury. Within most developed countries, members of sporting clubs participate in at-risk alcohol consumption at levels above that of communities generally. There has been limited research investigating the predictors of at-risk alcohol consumption in sporting settings, particularly at the non...

A variety of energy management systems are currently available for domestic domain, and many are concerned with real-time energy consumption monitoring and display of statistical and real time data of energy consumption. Although these systems play a crucial role in providing a detailed picture of energy consumption in home environment and contribute to influencing energy consumption behavior, ...
