Active Campus Using Mobile Technology

Abstract :

The traditional university campus is designed to develop a thriving community of lerners ,but modernity has introduced many stresses .Mobile computing holds the potential to make strong a campusâ„¢s traditional institutions of community through a process of indirect mediation i.e using personal wireless devices.These paper introduces Active-campus, a suite of personal services for maintaining an educational community. The design and implementation of ActiveCampus is described, which i ....etc

Active pixel sensor

An active-pixel sensor (APS), also commonly written active pixel sensor, is an image sensor consisting of an integrated circuit containing an array of pixel sensors, each pixel containing a photodetector and an active amplifier. There are many types of active pixel sensors including the CMOS APS used most commonly in cell phone cameras, web cameras and in some DSLRs. Such an image sensor is produced by a CMOS process (and is hence also known as a CMOS sensor), and has emerged as an alternative to charge-coupled device (C ....etc

Adaptive active phased array radars are seen as the vehicle to address the current requirements for true ?multifunction? radars systems. Their ability to adapt to the enviournment and schedule their tasks in real time allows them to operate with performance levels well above those that can be achieved from the conventional radars. Their ability to make effective use of all the available RF power and to minimize RF losses also makes them a good candidate for future very long range radars. ....etc

When reference signal for the FxLMS algorithm is taken from an acoustic sensor convergence can be very slow due to great eigen value spread. Using a non acoustic sensor, Such as a tachometer, cancellation of narrow band noise in the sensed fundamental frequency and harmonically related ones can be achieved very fast, although other periodic noises and underline broad band noise will remain.

Backward prediction errors resulting at the various stages of an adaptive lattice predictor(ALP) represent a a time-domain orthogonalization of the input ....etc

In this paper, the implementation of a shunt active power filter with a small series reactor for a three-phase system is presented. The system consists of multiple non-linear loads, which are a combination of harmonic current sources and harmonic voltage sources, with significant unbalanced components.The filter consists of a three-phase current-controlled voltage source inverter (CC-VSI) with a filter inductance at the ac output and a dc-bus capacitor. The CC-VSI is operated to directly control the ac grid current to be sinuso ....etc

RFID

Indoor localization has been an active area of research for several years. Especially as an enabling technology for location based services, indoor location support is of high interest for many business cases as well as for emergency/security scenarios. Location sensing represents a core component of ambient computing architectures, smart-environments and ubiquitous/pervasive computing architectures. The proliferation of wireless technologies, mobile computing devices, and the Internet has fostered a growing interest in location-aware s ....etc

active pixel sensor (APS)

An active pixel sensor (APS) is an image sensor consisting of an integrated circuit containing an array of pixels, each containing a photodetector as well as three or more transistors. Since it can be produced by an ordinary CMOS process, APS is emerging as an inexpensive alternative to CCDs.

Architecture
Pixel: The standard CMOS APS pixel consists of three transistors as well as a photodetector.
The photodetector is usually a photodiode, though photogate detectors ar ....etc
