3 An Inventory Model for Defective Items with Trade Credit and Inflation
W. Ritha, I.Antonitte Vinoline

Abstract-This paper develops an inventory model with imperfect items under the effect of inflation and time value of money in which demand is a deterministic function of selling price and advertisement cost. Here we have considered shortages are allowed and the holding cost is time dependent. In this process, a certain fraction of purchased items are defective. These items are reworked or refunded if they reach the customer. In this article, the model is considered with finite replenishment rate under progressive payment scheme within the cycle time. Here, the retailer is allowed a trade credit offer by the supplier to buy more items. This model aids in minimizing the total inventory cost by finding the optimal cycle length, the optimal time length of replenishment, and the optimal order quantity. The optimal solution of the model is illustrated with the help of numerical example.

4 New Approach on the Upgrading Policy for Redesigning the Components With Reliability and Quality Considerations
W.Ritha, S.Sutha

Abstract-On the performance based contracts, the manufacturer is highly responsible for the reliability and quality of the systems. She detects that the reparable component in the system has a poor reliability performance. To make the system reliable and quality, she decides to upgrade the performance of the system by redesigning the components with the latest technology. We introduce a model for studying the upgrading the system. It is done by replacing the reparable components preventively at time 0 and replacing one-by-one correctively. The inventory kept in stock after replacing at time 0 are decided to replace when an old components failed. The corrective replacement is performed either with the inventory kept in stock after replaced at time 0 or with the new ordered inventory. To enhance the quality of the system, it was decided to procure the high technology inventory. We assumed that the new high technical components have higher salvage value than other new components. We analyzed the minimum total cost which includes procurement/replenishment costs of the new components and high technological components, upgrading costs, repair costs of the new components, inventory holding costs and downtime costs. Through the numerical study, we derive the insights on which of the two replacements is the best one and we show how this depends on the reliability and quality of the components.

K.Gowri Ganesh

Abstract-In the daily newspapers, we come across several cases of house burglary, while people are away from houses (or) even when aged people/ ladies alone inside houses, causing heavy loss of valuables like gold jewels, silver articles and cash and also at the cost of life aged/ladies. Nowadays house burglaries on the increase in Cities and metros. In villages and small towns, people have their own conventional system of securing their houses/preventing such burglaries. In many establishments and shops, CCTV cameras have been installed to secure their properties, which on many occasion help only to do postmortem after the burglary has happened. So the aim of the project is to prevent the house burglary, as said by the golden saying “Prevention is better than Cure”. Our Paper implies a new design, which has a sensor kept at top of the door and the keypad present at the side of the door, which helps to sense the person standing in front of the door. If the owner or the tenant is inside the house, the system senses the person and the automatic calling bell is enabled. It is easy to know that the person visited our house. If the owner or the tenant is not present inside the house, a person enters a correct pin at key pad installed at the side of the door and unlocks the house. If the pin is not entered in 10 minutes, the camera turns on and it is on standby mode. If the person attempts to break the door, the vibration sensor installed at the backside of the door becomes active and the camera starts recording and alerts messages are sent to the owner or tenant, neighbor and the police with details of location of the house using GSM Module. In my case, the lock of house is operated Not by Manual KEY but DIGITAL ELECTRONIC KEY WITH NUMBERS. This electronic number locking system is common in Europe, UK, USA and Australia. We hope that this system will help to prevent the House Burglary.

13 Regulation of Voltage in Multi Distributed Energy Resources by Using Adaptive Voltage Control Technique
N. Karuna Sri, G.Poorna Chandra Rao

Abstract-In this paper adaptive voltage control method has been proposed to dynamically modify the control parameters of a single Distributed energy (DE) to respond to system changes such that the ideal response can be achieved. Theoretical analysis shows that a corresponding formulation of the dynamic control parameters exists; hence, the adaptive control method is theoretically solid. Then, control methods have been discussed in the case of multiple Distributed energy resources regulating voltages considering the availability of communications among all the Distributed energy resources. When communications are readily available, a method is proposed to directly calculate the needed adaptive change of the Distributed energy resource control parameters in order to achieve the ideal response. When there is no communication available, an approach to adaptively and incrementally adjust the control parameters based on the local voltage changes is proposed. Since the impact from other Distributed energy resources is implicitly considered in this approach, multiple Distributed energy resources can collectively regulate voltages closely following the ideal response curve.

17 Numerical Study for Nox Reduction in a Marine Diesel Engine Using SCR
Saurabh Verma, NITIN MALVIYA, SANTOSH KUMAR DIXIT

Abstract-Combustion of a modern slow velocity diesel engine produces exhaust gases which encompass gases together with NOx, SOx, CO, CO2. Of these NOx is most crucial due their feasible carcinogenic effect, contribution to photochemical smog formation over towns. This NOx converted to high-quality particles and nitrate aerosols. These particles get thru the lungs and small enough to pass via the tissue and enter the blood. They can then cause inflammations which subsequently purpose heart and lungs failure. The NOx can be reduced each by using pre-remedy like enhancing gasoline valve design, by means of varying the gasoline timing, blending of water with the gasoline and introducing water vapour in the combustion chamber and submit combustion remedy (e.g. SCR, Exhaust gasoline recirculation approach), of those SCR i.e. Selective catalytic reactor is part of the satisfactory tool for folks that are inquisitive about NOx reduction. With the SCR method, the exhaust gasoline is mixed with ammonia NH3 or urea (as NH3 carrier) earlier than passing via a layer of a special catalyst at a temperature among three hundred and 400°C, wherein NOx is reduced to harmless N2 and H2O. The SCR can reduce the NOx emission by ninety to ninety five % however it depends upon the diverse restricting factors like the temp difference of the reactor , the degradation or deactivation of catalyst over the years , SO2 to SO3 conversion which similarly converted to Sulphuric acid, Crystallization of Urea in the injector nozzle.

Ayush Bhardwaj, S.S Kushwah, Aruna Rawat

Abstract-The temperature dissemination delivered by the limited component heat investigation of the model is utilized as a part of the limited component basic examination to evaluate the most extreme passable heat inclination before splitting will start in the solid. Temperature contrasts inside of the solid happen when the heat being created by the solid is scattered to the encompassing environment bringing about the temperature at the surface of the solid to be lower than the temperature at the inside of the solid. In the meantime the heat created is a component of the temperature and time history of the solid. Consequently, singular areas in the solid will encounter diverse levels of heat. The temperature contrast between the solid at the focal point of the component and the solid in the external district will make stresses. On the off chance that the instigated elastic hassles are bigger than the early age rigidity of the solid, splitting will happen.

21 CFD Analysis of Helical Coil Heat Exchanger
Vijay Kant Pandey, Dinesh KumarKoli

Abstract-Heat exchangers are the vital engineering gadgets with wide variety of packages that include power plants, nuclear reactors,and refrigeration and air-conditioning systems, heat recovery system. Helical coil configuration is very powerful for heat exchangers because they could accommodate a large heat transfer region in a small space with high heat transfer coefficient. The study of this investigation is the effect of geometrical parameters on heat transfer in helical coil heat exchanger at three different mass flow rate 0.005, 0.02 and 0.05 kg/s. Helical coil was fabricated by bending 1000 mm length of aluminium tube having 6,8,10 mm tube diameter and each time coil diameter should be 40 mm and at same pitch 15 mm and at same length. The relation between pressure drop and mass flow rate has been obtained for three different curvature ratio 0.15, 0.2, 0.25 at three different mass flow rate.The result shows that by increasing the tube diameter 10 mm and at curvature ratio 0.25 at mass flow rate of 0.05 kg/s there is increase in pressure drop of about 12100 Pa (262.275 %) and Nusselt number also increases about 2.25% in comparison to tube diameter 6 and 8 mm and at mass flow rate 0.005 and 0.02 kg/s. This can increases heat transfer in helical coil heat exchangers. The increase in heat transfer are a consequences of curvature of the coil which induces centrifugal force to act on moving fluid resulting in development of secondary flow. Influence of three different curvature ratio on heat transfer (Nu), Reynolds number and pressure drop have been investigated through CFD and empirical correlation given by different researchers.
