Recent developments new telescopes advanced calibration software have completely changed data quality that was never possible old ...

Lettuce is a horticultural crop that has many enthusiasts and widely cultivated using hydroponic systems. One important factor for plant growth the need sufficient light to support process of photosynthesis. Efforts overcome lack use artificial comes from LED lights. This study aims determine effect ultraviolet lamp power on lettuce plants. was divided into two groups: control group without irr...

In recent years, along with the rapid development of LED technology, indoor positioning systems based on visible light communication (VLC) have been researched. In this paper, we propose an accurate indoor positioning method using white-light LEDs and a dual image sensor. Indoor LED lights are located at the ceiling in a room and broadcast information on their positions using VLC technology. A ...

Indoor farming is becoming a popular alternative approach in food production to meet the demand of a growing world population. Under this production system, artificial light provides the main source of illumination in sustaining plant growth and development. The use of light-emitting diodes (LEDs) is a popular source of artificial light for indoor farms due to its narrow light spectra, modular ...

11 generating contextual information which can be used to make applications which are adaptive and far more exible. The third generation of multimedia applications will not only exploit improvements in the network technology, but more importantly will take advantage of any contextual or location information made available. As mentioned earlier, this information will come from agents interpretin...
