  Authors: S.Ilaiyavel, A.Venkatesan
  JERS/ Volume I/ Issue I/ July-September, 2010/01-04  
 

ABSTRACT
Phosphating is the most widely used metal pretreatment process for the surface treatment and finishing of ferrous and non-ferrous metals. Due to its economy, speed of operation and ability to afford excellent corrosion resistance, wear resistance, adhesion and lubricative properties. It plays a significant role in automobile, process, and manufacturing industries. Manganese phosphate based coating decrease the coefficient of dry sliding friction considerably. The application of phosphate coating also improves the adhesive bonding of plain carbon steels. Phosphating is widely used method of reducing wear on machine elements and moving parts. Phosphate coating function as lubricants, in addition their ability to retain oil and soaps further enhance this action. Heavy manganese phosphate coatings supplemented with proper lubricants are most commonly used for wear resistance applications. The manganese phosphates widely used in automotive industry are the best to improve the ease of sliding and the reduction of associated wear of two steel surfaces sliding one against the other.This review addresses the various wear resistance application aspects of phosphating.

 

STRENGTHENING THE BACK BONE OF INDIAN ECONOMY THROUGH APPLICATION OF GIS IN AGRICULTURE

  Authors: Himanshu Hora
  JERS/ Volume I/ Issue I/ July-September, 2010/05-14  
 

ABSTRACT
India has agriculture as the main occupation. Basically, the farmlands are divided into small regions and some lands located close to the river, in the dry / wetly areas, hill areas, moderate rainfall areas, others. Land units being small, it provides farmers with a meager output, out of which some of the income is lost due to middlemen. The main crops grown here are vegetables, wheat, flowers, sugarcane, spices and others. Modern farming is about optimizing agricultural production. For this it is necessary to acquire knowledge of the whereabouts of assets and demands, analyzing this information for enhancing further business opportunities. This is where GIS can be used. In case of India, apart from the other agricultural benefits that GIS integrates water quality information, soil maps, crop and yield maps, etc. GIS could help in using various facts specific to India, like: It being a pilgrimage place, draws lacs of people annually thus demanding huge quantities of grains, flowers, spices, etc. Its proximity to a huge market like New Delhi, “Dynamic logistic” capital of India, upcoming national airport at different places in India can be utilized for exporting the flowers and vegetables, which have a small shelf life. GIS is used to compile the above mentioned factors for boosting the output, the trade, finding suitable markets, reducing the number of middlemen and thereby benefiting the farmer.

  Authors: Telang A K*, Rehman A, Dixit G, Das S
  JERS/ Volume I/ Issue I/ July-September, 2010/35-46  
 

ABSTRACT
Brake technology just like suspension & fuel system technology has come a long way in recent years. Automobile braking systems normally use brake discs of steel or grey cast iron, which are then paired with composite organic brake pads. These types of materials are suitable for use in braking systems with moderate loads, but vehicle manufacturers are tending to design increasing number of vehicles with more braking power. In addition, a history of high operating costs for on - highway vehicles and for aircrafts has encouraged designs for weight reduction with long service of braking systems. Redesigning of the braking system by substitution of lighter material like aluminum and carbon composite brakes primarily have been responsible for this state of the art technology, which is being used in aircrafts and formula one racing cars 1).The requirement is of the materials that have light weight, are strong, abrasion resistant and are not corroded easily. Composite materials provide such unique combination of properties. In this review the alternate materials for automobile brake applications with special attention to aluminum composites has been done.

 

ARTM: THE FUTURE OF RAILWAY TICKET COUNTER

  Authors: Ashish Parikh*, Ashish Joshi , L.C Patidar
  JERS/ Volume I/ Issue I/ July-September, 2010/47-50  
 

ABSTRACT
Smart cards are now a day is being used in many fields for identification, authentication, and data storage purpose. This paper is mainly concerned on utilities of smart cards in procuring railway tickets. Looking at the history, when the first railway opened, tickets were simply slips of paper with all the details written in by hand. Then, a more efficient system that consisted of small pieces of card, each pre printed with the entire journey details and stored in racks. Then, to speed up ticket issue would be to have a ticket machine in the counter. Tickets would be printed on demand and so reduce the number of tickets held in stock. But, there is always a great rush at ticket counters. Whether local or long distance trains, the queue is maximum for unreserved tickets. In such traffic conditions, there exists a problem that clerks must be assigned at ticket windows at all times, thus resulting in an increase in labor cost”. With these two issues in mind, it is the primary object of the present invention to provide an automatic ticket vending machine that will available railway tickets in public space such as shopping center/malls, airports, grocery stores, petrol/gas filling stations, restaurants, or any other place where large number of people may gather. The move is aimed at reducing the rush at ticket counters. To encourage usage of ticket machines and reduce the need for salespersons, machine prices may in some cases be lower than those at a ticket counter. This new idea invented automatic railway ticket machine.

  Authors: Prof.Indrajit Patel, Dr.C D Modhera
  JERS/ Volume I/ Issue I/ July-September, 2010/60-70  
 

ABSTRACT:
The sustainability issue for concrete construction industry is not arrived due to one or more reasons related to the material or the technology itself. This includes it consumes large quantities of precious natural materials; the fundamental binder in concrete is cement, a significant contributor to greenhouse gas emissions that are implicated in global warming and climate change. Majority of concrete structures suffer from durability issues which have an adverse effect on the resource productivity of the industry. Use of industry waste like fly ash, silica fume, grounded furnace slag to partly replace cementing material concrete system addresses all three sustainability issues, its adoption will enable the concrete construction industry to become more sustainable.The use of high volume fly ash (HVFA) concrete opts in very well with sustainable development. High volume fly ash concrete mixtures contain lower quantities of cement and higher volume of fly ash (up to 60%). The use of fly ash in concrete at proportions ranging from 35 to 60% of total cementations binder has been studied extensively over the last twenty years and the properties of blended concrete are well documented. The replacement of fly ash as a cementations component in concrete depends upon several factors. The design strength and workability of the concrete, water demand and relative cost of fly ash compared to cement. From the literature it is generally found that fly ash content in the cementitious material varies from 30-80% for low strength (20MPa) to high strength (100MPa). Use of High Volume Fly Ash (HVFA) concrete is very popular in countries like Japan, Canada and other developed nation since last century but due to certain limitations of application area the same has been not popularize worldwide. The limitations include slower early strength development, poor resistance to impact and abrasion and contribution to flexural as well.

  Authors: K.Lakshmi* and Dr. S.Vasantharathna
  JERS/ Volume I/ Issue I/ July-September, 2010/71-82  
 

ABSTRACT
With the fast changing technologies in the power industry, economic dispatch and unit commitment schedules become more complex and competitive problems. The generic Unit Commitment Problem (UCP) under restructured environment can be defined as to schedule the generators economically in order to maximize the profit of Generation Companies (GENCO’s)based on forecasted information such as power demand and prices. Generation Companies solves economic dispatch and unit commitment problem not for minimizing the total production cost as traditional but for maximizing their own profit. Hence, power prices become an important factor in decision making process. This paper presents a hybrid method between Lagrange relaxation and Genetic algorithm to schedule the optimal generating units. Simulations are carried out to evaluate the performance of the proposed technique. The results for 10 generating units -24 hours IEEE test system are compared with those obtained from traditional unit commitment.

AN EFFECTIVE APPROACH FOR IMAGE RECONSTRUCTION AND REFINING USING DEMOSAICING

  Authors: M.Jayasudha, S.Alagu
  JERS/ Volume I/ Issue I/ July-September, 2010/98-110  
 

ABSTRACT
The proposed work uses Demosaicing process for restoring full-color images from incomplete color samples acquired by single-sensor digital cameras. In the demosaicing process red, green and blue components of the image are acquired and interpolated to reconstruct the image. To restore a full-color image from its CFA samples, the two missing color values at each pixel are usually estimated from their neighboring CFA samples. This process is commonly referred to as CFA demosaicing (or CFA interpolation).and it has a substantial impact on the quality of the color images produced by a single –sensor digital cameras. If demosaicing is not performed properly, the restored images will suffer from visible artifacts, most dominated by zipper effects and false colors. The reconstructed images are affected by some visible and annoying artifacts. In this work a new effective algorithm is used to reduce these artifacts. This algorithm improves the performances of the demosaicing reconstruction. A refining step is included to further improve the resulting reconstructed image. It provides better performance with low computational cost.

  Authors: Simarjit Kaur, Sukhjit Singh
  JERS/ Volume I/ Issue I/ July-September, 2010/111-117  
 

ABSTRACT
Security is a major issue in highly computational resource sharing environment. Computer-based access controls can prescribe not only who or what process may have access to a specific system resource, but also the type of access that is permitted. Access control is a security measure that protects shared resources against un-authorized accesses. The resources that are protected by access control are usually called objects, whereas the entities whose accesses are regulated are termed users (or subjects). Access control [6] is required to preserve and protect the confidentiality of the information of the system and its resources. Access control is implemented by using simulated grid environment.

  JERS/ Volume I/ Issue I/ July-September, 2010/118-127  
 

ABSTRACT
A supply chain is a network of four -departments, which is involved in various activities like product procurement to distribution of final product. The purchasing has gained importance in supply chain management due to the factors like globalization and technological changes. In this paper the supplier selection for the leading glass product manufacturing industry is taken. Here, a versatile technique namely “Analytical Hierarchy Process” has been used to select the best vendor. When any vendor for a particular item make changes for the parameters like price, quality and performance improvement to deliver better quality product to customer, the whole hierarchy process for arriving at developing ranking of vendors is to be performed again for finding out the best vendor. So, a suitable standard programming logic was developed to meet current requirement. The package can be executed seven number of times with changing input parameters values thus serving the purpose.

  Authors: Shinde B. R, Jadhav K. M.
  JERS/ Volume I/ Issue I/ July-September, 2010/128-137  
 

ABSTRACT
Acoustical parameters such as adiabatic compressibility’s, specific acoustic impedances, intermolecular free lengths and solvation numbers have been estimated using standard relations from measured values of Ultrasonic velocities, densities and viscosities in wide range of concentrations at 303.15, 308.15, 313.15 and 318.15K temperatures for ZnSO4 + water system to study the ion-solvent interactions. It is observed that ion-solvent interactions are increases in increasing temperature and the concentration of Zn++ ions in water. However in very dilute solutions there is weak ion-solvent interactions and for moderate concentrations U increases steadily, which shows that ion-solvent interactions increases with concentrations suggesting structure promoting nature of Zn++ ions in cluster of water molecules.

ABSTRACT
Data are any facts, numbers, or text that can be processed. Data analysis is to find relationships among the data objects and then perform the remaining analysis like; clustering, classification, or anomaly analysis. A cluster is a set of objects in which each object is closer to every other object, and an entire collection of clusters is referred as clustering. On review of the papers and journals, it was found that the investors are finding difficulty in selecting better performing company for investment. Hence the objective of the research work was set to develop the clusters of NIFTY companies for better investment. Price per earnings ratios were calculated for all the 50 NIFTY companies during years 2008-2009 & 2009-2010. The specimen calculated Price per earning ratios for Reliance power was 171.70 and clustering of companies under sector wise were made based on the financial ratio analysis and clustering analysis. It was found that all 50 NIFTY companies were clustered and distributed as 11, 21 & 18 numbers for the P/E ratio <10, P/E ratio between 10-20 & P/E ratios >20 respectively for the year 2008-09 and 03, 18 & 29 respectively for the year 2009-10. Based on results, an investor is suggested to select a company and sector from the list for better investment. The recommended company for investment is reliance power (power-generation and distribution sector), since this company performed well in the years 2008-09 and 2009-10.

  JERS/ Volume I/ Issue I/ July-September, 2010/165-170  
 

ABSTRACT
Due to the tremendous demand and acute scarcity of fossil fuels, an attempt has been made to carry out the preparation of Bio Diesel from Rice Bran Oil. Now days, the use of microwave heating in reactions has gained much importance. So the effect of the microwave heating has been studied for the preparation of the Bio Diesel from Rice Bran Oil. The oil is reacted with commercial grade Methanol in the presence of Potassium hydroxide catalyst to undergo transesterification by operating the microwave at various powers from 160W to 800W. The Bio Diesel yield at various microwave input powers is compared. The rice bran oil and its bio diesel were analysed using Gas Chromatography and also their physical properties were determined by standard methods and compared to that of petroleum diesel. From the experimental results, it is observed that the maximum yield is obtained at the lowest input power of 160W. The yield decreases with increasing power and is least at 800W. The Rice Bran oil gave a maximum yield of 93.8%of methyl esters at the power of 160W. The properties of the Bio Diesel produced met all the specifications as specified by IS 15607: 2005.
