We would like to thank the editors and referees for their considerable efforts that improved our paper, and all of the discussants for their feedback, and their thoughtful and stimulating comments. Linear models are central in applied statistics, and inference for adaptive linear modeling is an important active area of research. Our paper is clearly not the last word on the subject! Several of ...

The replacement of the disappearing incandescent lamps will be realized at a significant scale by compact fluorescent lamps (CFLs). Light regulation is a popular feature that is easily provided by incandescent lamps using a simple electronic equipment, the dimmer. Dimming can be achieved by (dimmable) CFL lamps as well, however this is done in a completely different way than in case of the form...

This paper presents a high-frequency electronic ballast for HID lamps. A new fixed frequency dimming method with low EMI features is developed in this research. The proposed electronic ballast has the advantages of high power density, simple circuit and low EMI features. The circuit operating principle and design procedures are described in detail. A laboratory prototype was built and tested. T...

to measure soil water content (or soil matric suction) in thin layers of about 30mm, conventional gypsum blocks are not suitable. to carry out the task, mini-gypsum blocks were constructed using plaster of paris in an innovative fashion. a power relationship was found between the soil water content and the mini-gypsum blocks’ readings in kω. the calibration results showed that readings of m...

A brightness shift is demonstrated for moving ramp stimuli. The data suggest that the transient visual response to changing luminance is combined with the sustained response to produce an overall impression of brightness. We attribute the brightness shift to the saturation of the transient response: a limitation on the maximum transient when responding to rapid brightening or dimming. The brigh...

As a kind of renewable energy, the development and utilization solar energy are valued by many countries. To accurately provide basis for use in mainland China, optimized empirical model is adopted to analyze variation trends spatial patterns radiation (SR) during 1961–2016 based on data 31 SR sites 500 sunshine duration (SD) stations. The results indicate that there obvious discrepancies annua...

Community development efforts associated with the reduction in poverty and injustice historically have not benefited from the productivity and efficiency as well as private industry and government. Recently, declining entry barriers and Web ubiquity has spurred IS use for community development. This mini-track is designed to explore those uses and to encourage additional thoughts and models for...
