The benefits of an investment in an energy efficient durable good depend on the life of the investment. If the expected length of ownership is mis-estimated, this will bias calculations of the benefits of energy efficiency, including estimates of the energy efficiency gap. This paper estimates how expected ownership length affects household appliance choices. I leverage the fact that some types...

BACKGROUND The mechanisms of action of oral appliance therapy in obstructive sleep apnoea are poorly understood. Videoendoscopy of the upper airway was used during wakefulness to examine whether the changes in pharyngeal dimensions produced by a mandibular advancement oral appliance are related to the improvement in the severity of obstructive sleep apnoea. METHODS Fifteen patients with mild ...

This study compared the effects of 2 treatment protocols for correcting Class II disharmony. The first phase of treatment consisted of functional jaw orthopedics with either the Twin-block or the stainless-steel crown Herbst appliance; the second phase consisted of comprehensive fixed-appliance therapy in both protocols. Each of the 2 samples comprised 28 consecutively treated Class II patients...

SUMMARY The aim of this study is to describe a novel approach to revise maladaptive soft-tissue contour around an ileostomy. A patient with permanent ileostomy suffered from significant defects in soft-tissue contour due to scarring and wound contraction. He underwent autologous fat grafting to achieve sealing of his stoma appliance and improve cosmesis. Due to numerous surgeries, the stoma app...

We report from an ethnographical study of mobile service technicians at Telia Nära examining the process of travelling as a mobile activity, for the purpose of designing for new mobile IT use. Taking a point of departure from information appliance as a vision for designing information technology and activity theory as a framework for grasping activities in context elaboration is made upon how t...

INTRODUCTION Nocturnal enuresis has been found a common symptom among children with breathing problems and sleep apnea. The purpose of this study was to evaluate the therapeutic and placebo effects of slow maxillary expansion on nocturnal enuresis. MATERIAL AND METHODS Four children with enuresis aged 7-12 years were selected. Rigid acrylic expansion appliances were fabricated and delivered t...

Smart grid, which consists of many small microgrids, leads to a more stable and secure grid. In this paper, we proposed a game theoretic approach using a novel combinational pricing signal for the demand side management in a microgrid. We classified the appliance in a smart grid into appliance with elastic energy demand and appliance with inelastic appliance. We use game-theoretic approach to a...

Appliance-level power usage monitoring may help conserve electricity in homes. Several existing systems achieve this goal by exploiting appliances’ power usage signatures identified in labor-intensive in situ training processes. Recent work shows that autonomous power usage monitoring can be achieved by supplementing a smart meter with distributed sensors that detect the working states of appli...

Non-intrusive appliance load monitoring (NIALM) is to identify major energy guzzlers in a house or building without introducing extra metering cost. To develop an easy-to-use and scalable solution to energy disaggregation for contemporary large-scale appliance groups, we propose a Semi-Intrusive Appliance Load Monitoring (SIALM) approach in this paper. Based on a simple power model, a Sparse Sw...

Remote controls facilitate interactions at-a-distance with appliances. However, the complexity, diversity, and increasing number of digital appliances in ubiquitous computing ecologies make it increasingly difficult to: (1) discover which appliances are controllable; (2) select a particular appliance from the large number available; (3) view information about its status; and (4) control the app...
