ABSTRACT This project focuses on the development of a web based attendance register system‚ called mobile student attendance monitor. This project is motivated due to the fact that the student’s attendance record is the most important element which can reflect their academic achievement in the institutions. Mostly‚ the attendance register is circulated in the lecture rooms by the lecturers. This is a very time consuming method and not ideal for a large number of students in a big lecture hall.

Networks Lecture 2 Antennas and Propagation The notes in this document are based almost entirely on Chapter 5 of the textbook [Sta05]. Rappaport’s text is also a good reference for wireless signal propagation [Rap95]. 1 Antennas An antenna is an electrical conductor or a system of conductors that radiates/collects (transmits or receives) electromagnetic energy into/from space. An idealized isotropic antenna radiates equally in all directions. The directivity of an antenna is captured by its

WHAT ARE NANOSENSORS? Another wonderful invention of nanotechnology are nanosensors these are biological‚ chemical or surgical sensory edges or points which are used to detect and transfer nano particle information to the other devices such as microscopic/macroscopic world. There basic purpose is to develop medical nano products such as silicon computer chips and nano robots fabrications. Now a days there are many techniques which claims to develop nanosensors which involves top-down lithography

types of antennas. There are mainly two types of antennas: omnidirectional‚ and directional. Omnidirectional antennas are installed on most WLANS with AP’s that have them. Omnidirectional antennas do just what they sound like‚ which is transmit data in all directions at the same time. The signal can go horizontally and vertically; and up and down. However‚ there can be a dead spot in a minute area directly above the antenna which has no signal. One common example of this type of antenna is the dipole

INTRODUCTION: ENERGY FROM THE SUN The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the earth. Solar energy can be converted into other forms of energy‚ such as heat and electricity. In the 1830s‚ the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. Solar energy can

In an exhibit at the Tate Gallery in 1976‚ there is a make-believe artist‚ perhaps even well-known places his art work in a museum. This artwork is assembled with 120 bricks‚ and is arranged in a rectangular form on the floor. It is 2 bricks high‚ 6 across and 10 lengthwise‚ and therefore he calls it a “Pile of Bricks.” At the same time‚ a bricklayer’s assistant does something identical to what the previous well known artist did‚ but he is absolutely unaware of this incident. Therefore this

ABSTRACT The field of human computer interaction has been undergoing a new renaissance lately. While many companies have‚ and continue to spend millions to develop highly visually appealing GUIs and state-of-art interaction systems for the common users since the inception of desktops‚ the development of interactive systems for the disabled has taken a kick start relatively recently. And the Eye gaze systems are one of the most pivotal inventions in this context. The Eye gaze System is a communication
