Visible and Infrared Light Detection
Abstract: A circuit is made to detect either visible or infrared light. It is designed by using different light detectors, such as, infrared phototransistor, visible phototransistor, and photoresistor. If no light is shining on the detector in the circuit, the green LED is flashing. When the light is shining on the detector, the red LED starts flashing instead of the green one. Op-amp LMC 6482 builds up a simple voltage follower …

Oil lubricating tribology And additives for lubricating oil
Abstract: Numerous goods that are characterised by hundreds of basic chemicals and additions fall under the umbrella phrase "lubricating oil." Lubricating oils can either be synthetic or mineral-based. This article focuses on petroleum-based lubricating oils, which are composed of 80–90% petroleum hydrocarbon distillates and 10–20% additives and are used to lubricate a variety of internal combustion engines. Lubricating oil exposure occurs mostly through inhalation and skin contact in both occupational and …

BER Performance of Hybrid 2×8 SCM/WDM System Based on Raman Amplifier
Abstract: AbstractWhen subcarrier multiplexing (SCM) is combined with wavelength division multiplexing (WDM) the resultant hybrid multiplexing strategy can benefit from readily available commercial components. Hybrid SCM/WDM systems are quite useful for LAN and MAN applications. They can provide broadband integrated services to the subscriber. This paper investigates the performance of two module SCM transmitter that consist of eight binary phase shift keying modulated data streams each transmitted at a speed of …

Effect of Surface Wettability on the Surface-Driven Capillary Flow in SU-8 Microchannels
Abstract: AbstractSU-8 microfluidic devices have been fabricated by the maskless lithography. Passive capillary flow is suitable to manipulate liquid in the lab-on-a-chip systems. The surface-driven capillary flow of dyed water in each microfluidic device has been recorded and analysed. The measured static water contact angles are 72.6°and 81.2° on the hydrogenated amorphous carbon (a-C:H) deposited flat surface and Si-a:C:H deposited flat surface respectively. Either, a-C:H or Si-a:C:H has been deposited on …

Fourier Transform and Optical Analogy of the Sharply Pulsed E.P. Seismic Signals Propagating Through The Core of Earth
Abstract: AbstractLike light rays that encounter a water surface, seismic rays are governed by the laws of reflection and refraction. Eventually, there exist wave properties within these. Due to rigorous BIS (breakdown of integrated system) processes, severe consequences like earthquakes occur. The waves that are generated in an earthquake down into the interior of the earth are called earthquake waves or seismic waves. In the present paper, the author will consider …

Multi-way Protection Scheme to Handle Multiple Failures for Cost-Efficient Fiber-Wireless (FiWi) Access Networks
Abstract: AbstractFiber Wireless (FiWi) access networks prove themselves as promising broadband access networks. These networks enable users to access services in “Anywhere-Anytime” fashion. FiWi networks offer higher bandwidth and better flexibility at much lower price than passive optical network. As FiWi supports high data rate (typically about Gigabits per second), any failure may results in huge data loss. Therefore, to protect such loss of data, we need to design a more …

A Resource Efficient Fast Recovery Strategy for Survivable WDM Networks
Abstract: ABSTRACT In WDM networks when failure occurs, huge amount of data is lost in a fraction of second. Therefore, the failed connection request must be re-routed through backup route as soon as possible. For achieving fast connection recovery, the primary lightpath is either link or segmented protected. However, the strategies result in inefficient utilization of resources. In this paper, we present a resource efficient parallel signaling-shared path protection (PS-SPP) based …

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 …

Text based Graphical Password System to Enhance Security
Abstract: A graphical password is a type of authentication that requires the user to choose from a set of images in a certain order. For most people, remembering a graphical password is easier than remembering a text-based password. Passwords with graphics may be more difficult to remember. offer better security than text-based passwords. Humans can remember pictures much better than the text. To create passwords more memorable and less vulnerable to …
