It is very important to obtain very good low-rate codes with increased speed, due to its importance in modern communication systems. This paper proposes an effective method to achieve very-low-rate convolutional codes, with minimum generator polynomials and higher speed.
Human necessities are increasing day by day where as the factories are running out of resources. To meet these demands industries need to improve the quality and quantity of their production. One of the reliable and faster methods is by virtue of automation which not only increases the production level but also helps us to maintain space usage. At the same time industries needs to take care of creating...
The slab reheating in furnace can be modeled in the form of a partial differential equation. Artificial Neural Network based solutions are suggested as alternatives to numerical techniques. A trial solution of the differential equation is formed by embedding into it the boundary conditions. Then the network is trained to satisfy the differential equation. Simulated results are provided.
Abstract- Newer generations of diagnostic machines are based on digital technologies for data acquisition and consequently with the emergence of digital archiving systems for preservation of diagnosis is rapidly increasing. The goals of Content-Based Image Retrieval (CBIR) systems is to process on collections of images, extract features and based on visual queries, extract relevant image from a repository...
The principle behind the radiosurgery treatment is to irradiate the diseased target with radiation. The intensity of the dose received should be fairly low for each beam to protect the surrounding normal tissues. It is basically used for the treatment of brain tumors and other lesions. A classical radiosurgical system makes use of a rigid skeletal fixation of the region to be irradiated. This procedure...
Damage to structures may occur as a result of normal operations, accidents, deterioration or severe natural events such as earthquakes and storms. Most often the extent and location of damage may be determined through visual inspection. However, in some cases this may not be feasible. The basic strategy applied in this study is to train the first three natural frequencies of the cracked cantilever...
Power control in wireless sensor networks is vital to maintain reliable communication links and to maximize the battery life. Transmitting at high power not only reduces the lifetime of the nodes and that of the network, but it also introduces excessive interference. Hence it is essential for each node to transmit at minimal transmit power, thereby reducing interference and maintaining network connectivity...
The optical burst switching (OBS) based metro network is proposed to bridge the 'metro gap' between high performance core and LAN (local area network). Many media access protocols (MAC) have been suggested in literature for OBS based ring networks. This paper proposes a new MAC protocol for wavelength division multiplexing (WDM) based OBS metro ring network. The performance is analyzed through simulations...
Grid Computing refers to the combination of computer resources from multiple administrative domains to reach a common goal. Grids which are a form of distributed computing contains collection of resources that are available for an application to perform tasks. The resources in the grid are generally heterogeneous, geometrically dispersed and belong to different administrative domains. The important...
Fingerprints are being extensively used for person identification in a number of commercial, civil, and forensic applications. Most of the current fingerprint verification systems utilize features that are based on minutiae points and ridge patterns. However, this technology suffers from the problem of handling incomplete prints and often discards any partial fingerprints obtained. The major challenges...
The demand for health-monitoring wearable devices is increasing worldwide among scientists and clinicians. Low-power, low-voltage and low-noise attributes are important concerns that need to be addressed in circuits used for continuous personal health monitoring applications, to achieve long battery life. So the need for low-power low-voltage bio-amplifiers is increasing. These amplifiers receive...
Pulse Width Modulation is a method of controlling the amount of power to a load without having to dissipate any power in the load driver. PWM signals are widely used in telecommunications, power control systems, voltage regulation and in audio signal processing. This paper deals with the optimized power control in mobile applications. PWM power control systems became reality with the advent of modern...
Modulo Ten Search is a searching algorithm for finding a particular value in a list by performing modulus Ten of the number . Here the list will be partitioned into ten list based on modulo ten of the number. It searches an item by first taking modulo ten values and finally it undergoes a linear search method. A positional notation is required, but because integers can represent strings of characters...
The biological Deoxyribo Nucleic Acid (DNA) strand is found to be a promising computing unit. An attempt has been made in this paper to solve Chinese postman problem (CPP). In this paper, the thermodynamic properties of DNA have been utilised, along with other biochemical operations to obtain the optimal solution. Thermodynamics properties of DNA strand helps to use actual numerical values for distance...
Stiction is a common problem in spring diaphragm or piston operated control valves in process industries. A method is proposed by fitting an ellipse to the controlled variable (PV) and controller output (OP) plot and the maximum width of the ellipse is the apparent stiction .The mathematical modeling of the work is done with reference to the M. A. A shouktat choudhury valve stiction model. In this...
VLSI design techniques are the key to re-engineering the digital gadgets of any kind which are needed to be operated with lower power to ensure a longer backup time. Power reduction in Arithmetic Logic Unit (ALU) is needed for this requirement. Multipliers and adders are the most important structures which use a larger fraction of power in such arithmetic units. This paper analyses the use of an ancient...
In this paper, a system is developed which is implemented using PLC to automate the control of source changeover scheme in a Thermal Power Plant. In Thermal power plants, Fuel handling in the form of keeping good stock and supplying the same to the plant Boilers is a challenging task. For carrying out these tasks, electrical power is required to run conveyors for fuel transport from and to various...
The unified Modeling Language -Real Time (UML-RT) is a modeling Software -real time intensive systems. A real time system is any system that responds and acts in a timely manner. Thus time is a resource of fundamental concern and activities must be scheduled and executed to meet their timely requirements. Real time systems are often confronted with a need for concurrent execution activities to fulfill...
