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 an environment friendly working atmosphere and minimum energy consumption. Keeping all the above things in mind one of the important and pivotal industries of any generation, a galvanizing industry has been redesigned. This paper deals with a bolt galvanizing industry designed automatic with the help of PLC.

Due to progress in the vehicular technology, vehicles have gradually become a popular form of transportation in people's daily life. The stability and the performance of the vehicles has been the subject of much attraction. Road vehicle engines are controlled by engine management system (EMS) in which fault identification & diagnosis is the vital part. The pressure of the engine intake system always demonstrates the engine condition and affects the volumetric efficiency, fuel consumption and performance of internal combustion engines. Conventional engine diagnostic technology already exists through analyzing the differences between the signals and depends on the experience of the technician. Obviously the conventional detection is not a precise approach for pressure detection when the engine in operating condition. In this paper, a system is consisted of pressure signal feature extraction using discrete wavelet transform (DWT) and fault recognition using the neural network technique. To verify the effect of the proposed system for identification, the radial basis function network (RBFN) is used. It has been observed that the training procedure can be accomplished in short time. Also, the conventional flaw of too much reliance on the experience of technicians can be reduced.

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 beam in a genetic algorithm controller which works on the principle of evolution. Here Finite Element Analysis is used to model the crack. The result from the Genetic Controller has been compared with the Finite Element Analysis result. It has been found out that the results are in close agreement with each other.

Spacecraft attitude control system simulator helps to create an environment utilized for simulating attitude control system of satellites. A set of three inertial wheels is used as primary actuators for the attitude control. A flywheel is a disk with significant moment of inertia which is used as a storage device for rotational energy, i.e. momentum can be imparted on it or taken away from it. The hardware simulator provides a real-time freedom of motion in the axis of rotation. The spacecraft simulators are widely used to develop and verify spacecraft control techniques required by modern spacecraft applications. The simulator find many applications in various ongoing research flywheel energy management, non linear compensation of an under actuated system, the problems of attitude and orbit control and development of inertial wheels. The simulator provides the flexibility to experimentally implement many types of control techniques. The simulator is employed to develop, improve and carry out the objective tests of the actuators and the algorithms developed for the attitude control of the spacecraft.

Increasing volume of web has resulted in the flooding of huge collection of web documents in search results creating difficulty for the user to browse the necessary document. Clustering is a solution to organize search results in a better way for browsing. It is a process of combining similar web documents into groups. For web page clustering, terms (features) can be extracted from different parts of a web page. Giansalvatore, Salvatore and Alessandro[1] have extracted terms from entire web page for clustering Stanis law Osinski et al.,[2] have considered terms only from snippets. A new method is introduced in this paper which extract terms from URL, Title tag and Meta tag to produce clusters of web documents. The reason for selecting these parts of a web page is that they contain keywords which are available in a web page. Clustering algorithm used in this paper is K-means. Proposed method of clustering is compared with snippet based clustering in terms of intra-cluster distance and inter-cluster distance.

In this paper, we propose a dynamic and efficient compiler based scheduling algorithm for multicore processors.Here, scheduler takes sub-blocks of a basic block which can be executed independently and maps these sub-blocks on to multiple cores to achieve less execution time. Instructions inside the sub-blocks are in Static-Single Assignment (SSA) form and have only true dependency, but all sub-blocks are disjoint. Scheduler is dynamic because, before mapping subblocks on to cores it checks the register requirement and cycles required for execution of each block and merges the sub-blocks if required which will lead to many outshoots. Despite having a number of new features, this algorithm has admissible time complexity, is economical in terms of the number of core used and is suitable for a wide range of graph structures.

This paper proposes an approach to recognize handwritten Tamil Character recognition. Handwritten Tamil character recognition refers to the process of conversion of handwritten Tamil character into printed Tamil character. It is difficult to process handwritten characters due to the great variations in writing styles, different size and orientation angle of the characters. In the proposed system the scanned image is preprocessed and segmented into paragraphs , paragraphs into lines, lines into words and words into character image glyph. Each character image glyph is subjected to feature extraction procedure, which extracts the features such as character height, width, number of horizontal and vertical lines, horizontally and vertically oriented curves, number of circles, number of slope lines, image centroid and special dots.

Petri nets generating all the 2^n binary n-vectors as their marking vectors are not only of theoretical interest but also are of practical importance. In this note, we demonstrate the existence of a disconnected 1-safe Petri net whose reachability tree is homomorphic to the n-dimensional complete lattice L_n. This makes the problem of characterizing the 1-safe Petri nets that generate all the binary n-vectors as marking vectors exactly once appear more intricate.
