Imbibing intelligence to these devices is through a system called “PLC SYSTEM”. It is the evolution or further development of the computing system. Its applications provide marvelous opportunities for ingenious use of computer technology. Almost every new system introduced is an example of PLC System.

PLC SYSTEM are combinations of hardware and software that are mounted on compact electronic circuit boards integrated into devices. They are engineered or intended to perform one specific function in a specific environment. An important decision in the design of an plc system is the selection of the hardware configuration around which the rest of the system is to be built. It is a chip that contains a PLC , some memory & I/O interface circuitry useful in  applications and is often called an ‘PLC BASED Control System’ as they perform important control functions, and are based similar to  micro controller.

Abstract

The field automation has stretched its wing across all direction. This automation is not a new word, it was born when the great Creator created this universe, galaxies and solar system. The revolution of earth is considered to be an automated system. And this automated system is now used here as a safety system for vehicle. It is the evolution or further development of the computing system. Its applications provide marvelous opportunities for ingenious use of computer technology in the name of PLC based systems.. Almost every new system introduced is an example of PLC based System. These systems are more intelligent and autonomous PLC based Systems are combinations of hardware and software that are mounted on compact electronic circuit boards integrated into devices. They are engineered or intended to perform one specific function in a specific environment. An important decision in the design of an PLC based system is the selection of the processor(s) around which the rest of the system is to be built. It is a chip that contains a microprocessor, some memory & I/O interface circuitry useful in PLC based applications and is often called an „PLC BASED SYSTEM” chips as they perform important control functions, and are based on micro controller.

The current topic “Automation of car” that we are going to present is one of the fine examples of PLC based System.

Autonomous car: There are many paradigm shifts taking place due to information explosion and the concept of autonomous vehicle is one shift. The car, which is PLC based, can simulate the human driver completely and direct the vehicle on the road.

Autonomous vehicle is the drastic change in technical brilliance and developments in different fields with PLC BASED SYSTEM as pioneer.

Abstract

To ability to control the transport of individual electrons in Single Electron Tunneling (SET) based circuits creates the conditions for Single Electron Encoded Logic (SEEL). This paper involves the implementation of full adder using SEEL elements. In SEEL the designing of linear equations for a specific logic circuit with the representation of positive, negative weights and desired threshold value can be implemented with a single electron box. The concept of SEEL realizes the logic behaviour by controlling the capacitance of bias for adjusting the gate threshold to realise the desired logic with inverting or non-inverting buffer. The re-configurability of gates is done by varying the bias capacitance. After introduction of the threshold gate and buffer/inverter, which serve as basic circuit blocks, SEEL implementations as the full adder are proposed and verified by simulation. Finally, the area, switching delay, speed power product and power consumption of the elements are compared with SEEL 1-bit full adder to n-bit adder.

Abstract

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers together forms an OFDM symbol. Each sub-carrier in an OFDM system is modulated in amplitude and phase by the data bits. The process of combining different sub-carriers to form a composite time-domain signal is achieved using Fast Fourier transform. In this paper we propose an idea for implementing complex multipliers and FFT computers using [bit serial approaches and distributed arithmetic concepts]. Usually multiplication is done by successive additions or by design of parallel multipliers. Instead we propose a [Bit Shift Accumulation] technique based on [Modified BOOTH'S Algorithm] to implement [Complex Multipliers]. By this way the [speed of multiplication] performed is increased and the [chip area consumed] is decreased which results in [low power consumption]. Fast Fourier transforms are taken using RADIX 4 butterfly using [our Complex multiplier] as and when the bit arrives thus increasing the speed of OFDM transceivers.

Abstract

We introduce a novel approach for image registration for high dynamic range (HDR) videos. We estimate a translation vector between two low dynamic range (LDR) frames captured at different exposure settings. By using row and column histograms, counting the number of dark and bright pixels in a row or column, and maximizing the correlation between the histograms of two consecutive frames, we reduce the two-dimensional problem to two one-dimensional searches. This saves computation time, which is critical in recording HDR videos in real-time. The robustness of our estimation is increased through application of a Kalman filter. A novel certainty criterium controls whether the estimated translation is used directly or discarded and extrapolated from previous frames. Our experiments show that our proposed approach performs registration more robustly on videos and is 1.4 to 3 times faster than comparable algorithms.
