Familial factors in anorexia nervosa: a community-based study

A group of 51 cases with teenage anorexia nervosa (AN; including a total population of cases from one birth cohort) were compared with a sex-, age-, and school-matched group of 51 cases on familial factors. The subjects were examined at age 16 and 21 years. In the first study, mothers of both groups were interviewed regarding physical and psychiatric disorders among first-degree relatives. In the

Efficiency of Off-Board, High Power, Electric Vehicle Battery Chargers with Active Power line Conditioning Capabilities

Abstract in UndeterminedA comparison is made of battery charger topologies for electric vehicles. The chargers are all off-board, and capable of active power line conditioning and bi-directional power flow to compensate local utilities during peak power loads. The active power line conditioning capability is important, since an increase of battery chargers based on ordinary diode rectifiers would

Cylinder Individual Efficiency Estimation for Online Fuel Consumption Optimization

Engine efficiency is often controlled in an indirect way through combustion timing control. This requires a priori knowledge of where to phase the combustion jiff different operating points and conditions. With cylinder individual efficiency estimation, control strategies aiming directly at fuel consumption optimization can be developed. This paper presents a method to estimate indicated efficienc
