The reduction of the consumed energy in modern selforganizing communication systems in a dense urban environment is a challenging task that requires coordination in management operations for the most effective use of network resources. Configuration and performance optimization tasks affect energy consumption of specific components and energy-related metrics of different devices. We propose a n...

Fueled by the widespread deployment of information communication technologies, the notion of collaborative consumption has become popular in recent years. Traditionally, individuals have viewed ownership as the most desirable way to access products. In recent years, individuals have shown a robust appetite for collaborative consumption. While the prevalence of collaborative consumption activiti...

OBJECTIVES To compare the effects of a computer-assisted dieting intervention (CAD) with and without self-management training on dieting among 55 overweight and obese adults. METHODS Random assignment to a single-session nutrition intervention (CAD-only) or a combined CAD plus self-management group intervention (CAD+G). Dependent variables were the number of servings from various food groups ...

Dynamic Power Management (DPM) is a technique to reduce power consumption of electronic system by selectively shutting down idle components. In this article we try to introduce back propagation network and radial basis network into the research of the systemlevel power management policies. We proposed two PM policiesBack propagation Power Management (BPPM) and Radial Basis Function Power Manage...

This paper presents an original approach to reduce energy consumption in an IEEE 802.15.4/ZigBee cluster tree network related to a backbone network. Our approach uses an enhanced mobility management of end devices combined with a rate adaptation algorithm. The mobility management approach anticipates link disruption and relies on a speculative algorithm that does not require scanning neighbor c...

Fuelwood is the principal energy resource for mil­ lions of households around the world, yet its use, availability and management remain poorly understood in many areas. We document fuelwood consumption, growth/yield and standing biomass in a Bhutanese village and alpine area used season­ ally by villagers where the government is concerned about harvesting in a recently designated national park...
