Neural Networks have become very famous topic of interest since last few years and are being implemented in almost every technological field to solve wide range of problems in an easier and convenient way. Such a great success of neural networks has been possible due to their sophisticated nature as they can be used with ease to model many complicated functions. The neurons are interconnected by the fibrous structures called dendrites by the help of special gapped connections called synapses. The electric impulses (called Action Potentials) are used to transmit information from neuron to neuron throughout the network.
Introduction to Image Processing
Image processing is a method to convert an image into digital form and perform some operations on it, in order to get an enhanced image or to extract some useful information from it. It is a type of signal dispensation in which input is image, like video frame or photograph and output may be image or characteristics associated with that image. The image processing is not just confined to area that has to be studied but on knowledge of analyst. Association is another important tool in image processing through visual techniques. So analysts apply a combination of personal knowledge and collateral data to image processing.
Home Automation : An Overview
Home automation is a term used to describe the working together of all household amenities and appliances. For example, a centrally-controlled LCD panel can have the capability to control everything from heating, air conditioning, security systems, audio systems, video systems, lighting, kitchen appliances, and home theatre installations.It is essential that different controllable appliances be interconnected and communicate with each other. The basic aim of Home automation is to control or monitor signals from different appliances, or basic services. A smart phone or web browser can be used to control or monitor the home automation system.
Introduction to Robotics
Other than the sci-fi movies, the robots can be seen around us assembling the cars, in bottling factory etc. The robots have been in the industry for last two decades because of their continuous working ability in an atmosphere, where humans are not even able to stand for minutes, without any supporting equipment, like space.Basic structure of robots is very much similar to humans. How do humans sense? For example a human sees something and sends neural signals to the brain via neurons and reacts accordingly. The development of all these senses in Robots artificially is achieved through Sensors.
PLC : An Overview
Programmable logic controller is a digital computer used for the automation of various electro-mechanical processes in industries. These controllers are specially designed to survive in harsh situations and shielded from heat, cold, dust, and moisture etc. The hardware components of a PLC system are CPU, Memory, Input/Output, Power supply unit, and programming device. PLC consists of a microprocessor which is programmed using the computer language. A visual programming language known as the Ladder Logic was created to program the PLC. The program is written on a computer and is downloaded to the PLC via cable. These loaded programs are stored in non – volatile memory of the PLC.
Mechatronics : An Overview
Mechatronics refers to the successful combination of mechanical systems and electronics. In mechatronics, traditional systems of mechanical engineering are [[wysiwyg_imageupload::]]fused together with components from computer science, mathematics and electrical engineering. Mechatronics provides solutions that are efficient and reliable systems. Mechatronic systems mostly have microcomputers to ensure smooth functioning and higher dependability. Few examples of mechatronics system are automated guided vehicles, robots, digitally controlled combust engines and machine tools with self-adaptive tools, aircraft flight control and navigation systems, and smart home appliances.
Bluetooth Technology : An overview
Bluetooth is a wireless technology used to transfer data between different electronic devices. The distance of data transmission is small in comparison to other modes of wireless communication. This technology permits hands free headset for incoming voice calls, ability of printing and fax, and automatic synchronization of PDA. A Bluetooth device is comprise of an adapter. A Bluetooth adapter can be available in the form of a card to connect the device or integrated into an electronic device. Link Management Protocol (LMP) is responsible for peer – to – peer message exchange when the electronic devices interfere in each other’s radio range.
Biometrics : An Overview
Though most important application related with biometrics is that of security, it is used as the computer interface too. A range of Biometric applications are being used for authenticating person’s identity. With the use of various features including fingerprints, face, signature, and iris, a person is identified. When someone uses biometrics for the first time, it’s called enrollment. In this stage, information is stored by the individual. In succeeding uses, information in biometric system is compared and detected with one stored in the enrollment. One should make sure that storage as well as retrieval of the information is done in a secure manner.
Wireless Communication and types
Wireless communication is among technology’s biggest contributions to mankind. Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors. The transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication). Some of the devices used for wireless communication are cordless telephones, mobiles, GPS units, wireless computer parts, and satellite television. The growth of wireless network has enabled us to use personal devices anywhere and anytime.
RFID : An Overview
RFID is a tracking technology used to identify and authenticate tags that are applied to any product, individual or animal. Radio frequency Identification and Detection is a general term used for technologies that make use of radio waves in order to identify objects and people. Purpose of Radio frequency Identification and Detection system is to facilitate data transmission through the portable device known as tag that is read with the help of RFID reader; and process it as per the needs of an application. Information transmitted with the help of tag offers location or identification along with other specifics of product tagged – purchase date, color, and price. Typical RFID tag includes microchip with radio antenna, mounted on substrate.
