WHAT IS COLOR GOOD FOR? Although our distant ancestors probably first used color vision to find fruit in trees, it is still useful to us. Even though most of us will never have to defuse a bomb (Figure 1), colors are used to send all sorts of important messages in the modern world. Traffic lights turn from green to red to tell us to stop (Figure 2), warning lights turn orange on the car dashboa...

Methods of light treatment such as light schedule, intensity or illuminance, and color are important factors that influence avian productivity. Therefore, artificial illumination has been widely used in modern poultry husbandry. Although progress had been made in understanding of the effects of light schedule and intensity on avian growth, effects of light color on avian growth are not clear. I...

This paper describes a working prototype device, PopCAD, for straightforward, tangible 3-dimensional input and design. PopCAD is a paper-based pop-up computational artifact that can be carried about easily and unfolded into its "working" instrumental form. When unfolded, PopCAD allows the user to switch on LED lights in a 3D spatial array; the positions of these lights are sent to a desktop com...

Electricity has become are indispensable component in the lives of all today. Street lights are one of the most crucial parts for public sector and urban areas. The traditional street lighting System which controlled manually has disadvantages like high power consumption, high cost and there is no effective monitoring system. This paper is proposes an Automatic Solar Panel Based LED Street Ligh...

There is great concern over growing road accidents and associated fatalities. In order to reduce accidents, improve congestion and offer smooth flow of traffic, several measures, such as providing intelligence to transport, providing communication infrastructure along the road, and vehicular communication, are being undertaken. Traffic safety information broadcast from traffic lights using Visi...

The present work aims to explore the potential improve quality of purslane microgreens by combining water salinity and LED lighting during their cultivation. Purslane plants were grown in a growth chamber with light insulated compartments, under different sources on 16 h d−1 photoperiod—fluorescent lamps (FL) two treatments, including red blue (RB)) spectrum red, far (RB+IR) lights spectrum—whi...
