Steady State Visual Evoked Potential Based Brain Computer Interface System
Abstract: The steady-state visual evoked potential (SSVEP) is a brain response that can be measured by an electroencephalogram (EEG) when a subject looks at periodic luminance- or contrast-modulated stimuli. In this study, flickering Light Emitting Diode (LED) is used as visual stimulation. Mostly, brain response is recorded using an electroencephalograph (EEG) and recorded in the brain's occipital lobe which is associated with human vision. The study encompasses key stages, beginning with …

Kinetic drum composting of Kitchen and garden waste
Abstract: This paper discusses the drum filling process as one of the best method of biodegradable waste management technique, as it reduces tones of biodegradable waste from environment. And some fundamental investigations are established to demonstrate the potential of harvesting electrical energy from by waste. The energy is harvested by embedding moisture Sensor into the plant (compost) to allow flow of ions and hence generate electricity. In addition, it is shown …

Organic Light Emitting Diodes (OLEDs)
Abstract: This paper gives the brief analysis of Organic Light Emitting Diodes (OLED) .OLED is a special type of solid-state lighting source. An OLED device is typically formed in a sheet with emissive organic layer(s) located between a cathode and anode and deposited on a substrate. The substrate can be rigid such as glass or metal or flexible made of a polymer plastic. The number of emissive layers depends on the …

Electroluminescence
Abstract: Electroluminescence (EL) is a kind of luminescence which is an optical and electrical phenomenon in which light is emitted by certain materials due to the passage of an electric current or a strong electric field. The mechanism behind electroluminescence is the radiative recombination, or spontaneous emission. The electrons get excited and release their energy as photons. The holes and electrons before recombining are separated either by doping the given material …
