Comparative study of AODV with malicious environment and the USOR

Dr K Butchi Raju

By the performance analysis of two protocols AODV and USOR implemented in ns2 we made a comparison between them. USOR is efficient as it uses a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that USOR can well protect user privacy against both inside and outside attackers. Successful implementation of unlinkability and unobservability property of USOR not only has satisfactory performance compared to AODV, but also achieves stronger privacy protection than the existing systems when in the malicious environment. Usage of the stronger encryption techniques in unobservable protocol makes the more data secure. In this paper we are going to compare the protocols AODV and USOR. The performance of the network mainly refers by using the packet delivery function and the over head of the packet to reach the destination. Here we are analyze overhead and packet delivery function of the two protocols and made the comparison between them.

Many e-Government services till date have been created based on the existing services and own understandings, rather than based on citizenâ€™s need and interests. Very little data is available about local government officials and citizenâ€™s want and need. The proposed study will analyze the use of IT and e-Governance practices, develop & document the conceptual model of e-Govt, define components, component attributes, and the component relationships for each model. The model will be based on the citizenâ€™s viewpoint which is expected to be quite different from a model based on a government agencyâ€™s viewpoint.

Study on Chemical Treatments of Jute Fiber for Application in Natural Fiber Reinforced Composites (NFRPC)

Research and studies on the use of natural ï¬bers as replacement to man-made ï¬ber in ï¬ber-reinforced composites have increased and opened up further industrial possibilities. Natural ï¬bers have the advantages of low density, low cost, biodegradability, recyclable, low pesticide and thus environmentally friendly. However, the main disadvantages of natural ï¬bers in composites are the poor compatibility between ï¬ber and matrix and the relative high moisture sorption. Therefore, chemical treatments are considered in modifying the ï¬ber surface properties. In this paper, the different chemical modiï¬cations and treatments on jute ï¬bers for use in natural ï¬ber-reinforced composites are reviewed. Chemical treatments including alkali, permanganate treatments and others are discussed. The chemical treatment of ï¬ber aimed at improving the adhesion between the ï¬ber surface and the polymer matrix may not only modify the ï¬ber surface but also increase ï¬ber strength. Water absorption of composites is reduced and their mechanical properties are improved.

Experimental Study on Strength Characteristics of Self Curing Concrete with Cement Replacement by Fly Ash

P. Manzoor, Dr. E. Arunakanthi

Curing is an important process in construction. It regulates the strength properties of concrete. More water (with the domestic usage quality)is required for the curing process in construction. Large quantity of water is required in construction only in the curing stage. During the curing process, large amount of water is wasted as evaporation. Scarcity of water around the globe gives insufficient quantity and inefficient quality of water for domestic purpose. In this situation, water for curing purpose is a joke. For this many experiments are done on self curing concrete. Self curing agents like polyethylene glycol etc., is used in concrete. These agents retard the water loss from concrete, so that sufficient amount of water (poured at the time of mixing of concrete) is retarded and sufficient for curing of concrete in later stages. Polyethylene Glycol-400 is used in this experiment as a self curing agent. It is a harmless polymer and easily available in laboratory chemical suppliers and its effectiveness is very high even in the small quantities. The effectiveness of PEG-400 is high up to 0.5% of weight of cement. Many experiments are done on conventional concrete to convert into self curing concrete without any replacement of fly ash. Now-a-days fly ash is used as a cement substitute. The objective of the present experimental study is to analyse the possibility of using fly ash in the place of cement in self curing concrete up to 30% (because is code-10262:2009 gives fly ash replacement in concrete up to 20%). This experimental study was carried out on the three mixes-conventional mix, self curing concrete mix with PEG-400 (0.3%of weight of cement as constant),self curing concrete with replacement of cement by fly ash up to 30% with PEG-400 (at 0.3% of weight of cement is taken as constant). The obtained results are describing the comparisons between the strength characteristics of the conventional concrete specimen with curing, self curing concrete with no fly ash without curing and self curing concrete with fly ash ( in place of cement upto30%by weight) without curing. These results are taken at constant proportions of self curing agent, i.e.PEG-400 (0.3% by weight of cement).

Enhancing the surge margin of a Centrifugal Compressor with different Blade Tip Geometry

Ibrahim Shahin

The reliability operation for small fuel cells and hybrid fuel cell with gas turbine requires centrifugal compressor surge prevention. This study concerns a high speed centrifugal compressor stage with different blade tip geometries. The investigations were performed with unsteady three-dimensional, compressible flow simulations. A novel parameterization method has been developed to alter the tip geometry of an impeller blade. Different tip geometries are investigated includes flat tip blade, main blade winglet, main and splitter blade winglet and finally pressure side grooved tip. The performance and internal flow results are presented at surge, design and near choke points. The conclusion is that the tip geometry has a significant effect on the compressor performance and the operation stability at lower flow rates. The pressure ratio and surge margin for the blades with winglet have been improved, and decreased for the grooved tip geometry. More uniform flow at impeller outlet with winglet blade. The use of winglet tip displaces the tip leakage vortex away from the blade and weakening the impingement effect. The winglet tip reduces the aerodynamic losses by unloading the tip section, reducing the leakage flow rate and turning the leakage flow in a more stream wise direction.

Furnaces are useful for melting different materials for casting process. In this research paper, we had done advanced heat transfer analysis of induction furnace wall made of silica ramming mass using explicit finite difference method. We have divided actual geometry of furnace refractory wall into 14 elements and 24 nodes. We have derived explicit finite difference equations for all 24 nodes. We have calculated temperature distribution and thermal stress distribution for all different nodes with respect to time. We have plotted graphs for maximum temperature v/s time and maximum stress v/s time. We found that results indicate the effect of thermal fatigue in the induction furnace wall for silica ramming mass. The analysis is very helpful in understanding how thermal fatigue failure of refractory wall happens.

Elliptic-Curves Cryptography on High-Dimensional Surfaces

Alberto Sonnino, Giorgio Sonnino

We discuss the use of elliptic curves in cryptography on high-dimensional surfaces. In particular, instead of a key exchange protocol written in the form of a bi-dimensional row, where the elements are made up with 256 bits, we propose a Diffie-Hellman key exchange protocol given in a matrix form, with four independent entries each of them constructed with 64 bits. Apart from the great advantage of significantly reducing the number of used bits, this methodology appears to be immune to attacks of the style of Western, Miller, and Adleman, and at the same time it is also able to reach the same level of security as the cryptographic system presently obtained by the Microsoft Digital Rights Management. A nonlinear differential equation (NDE) admitting the elliptic curves as a special case is also proposed. The study of the class of solutions of this NDE is in progress.

Weldability and Post Weld Heat Treatment of T23 Boiler Grade Steel

M.Mohandas Pravin kumar, M.Deepak Kumar, V.Karthik

T23 is a low alloy ferritic steel used for boiler super heater and re-heater tubes and water panels in complex fuelled power plants as they exhibit superior high temperature strength and creep behaviour compared to other low alloy ferritic steels. T23 steel is in bainitic structure which holds greater toughness than tempered martensite and also they possess increased resistance to thermal fatigue. With the help of T23 steel, the weight and piping component of the boiler can be reduced. The microstructure of the weldment without proper Post Weld Heat Treatment (PWHT) was not in equilibrium state which led to the secondary hardening during subsequent exposure at high temperature. So there occurred a significant increase in hardness due to non-tempered weld joints and decrease in toughness. Therefore, Post Weld Heat Treatment for T23 steel is necessary. Using Tungsten Inert Gas (TIG) process, the T23 steel was welded under suitable welding parameters (welding current, voltage and shielding gases). A study was done to know the effect of Post Weld Heat Treatment on T23 steel and also the influence of welding parameters. Hardness of T23 steel was measured. The heat treated specimen is examined through Optical microscope and Scanning Electron Microscope. Finally it was noticed that the Post Weld Heat Treatment has enhanced the mechanical properties as well as the metallurgical arrangement of the T23 steel.

Traditional rice varieties suits best for obtaining flour since they nutritious and well adapted to the local setup. This study reports the impacts of physio-chemicals modifications of rice flour obtained from four traditional rice varieties grown in Sri Lanka in making of bread. Four traditional rice varieties namely Madatuwalu, Kaluhenati, Panchaperumal and Rathdal were selected and grains were soaked in 0.5M or 1M NaHCO3 solution for one hour followed by dehydration at 100oC for one to two hours. Functional properties of the modified rice flour such as, Water Solubility, Swelling Power and Water Absorption Index were determined. The treatments tested were shown significant effects (p < 0.05) on functional properties of all four flour types. Dipping in 1M NaHCO3 solution for one hour followed by dehydration for two hours at 100oC was the best treatment and Madathuwalu was the highest performing flour type for all the functional properties. Hence, Madathuwalu was selected after the application of best treatment to develop rice flour incorporated composite bread. The results showed that composite bread developed by substituting 40% wheat flour with modified rice flour resulted in the similar sensory attributes to bread developed with 100% commercial wheat flour.

Solution processed small molecules have drawn attention from the researcher and give competitive alternative to the polymer counterpart due to their advantages such as well define molecular structure and high purity without batch to batch variation. By incorporating D-A concept for structural framework, the photovoltaic performance of the small molecules had a great progress in recent years. The development of thieno[2,3-c]pyrrole-4,6-dione (TPD) as building block for small molecule Donor-Acceptor (D-A) structural framework had many potential advantages. This feature article reviews summarizes the progress of TPD based small molecules in organic photovoltaic cells.
