Because of that, researchers have been searching for alternative solutions aiming the rational use of finite resources and the development of new technologies. In this study, the effects of glass waste and "rock dust" were investigated, both pulverized in high energy mill for stabilization of a typical clayey soil. Accordingly, UCS and tensile strength by diametral compression were conducted on soil specimens together with the addition of 10% and 50% of glass and rock. The results showed that 10% of glass content increased up to 21% on UCS compared to soil "in natura". Furthermore, by adding "rock dust" waste, the strength also improved up to 60% on UCS and 8% on TS. In particular, the mechanical parameters indicated 10% of content, on either glass or rock waste, to be the effective amount on stabilization of clayey soil.

Adequate lubrications require lubricant (oil) with sufficient film strength to withstand bearing pressure and viscosity index low enough to allow adequate flow when subjected to heat. The system consist of the tanks (storage, settling, sump and head), lube-oil pumps, strainers, oil coolers, piping, valves, and fittings, lubricating oil purifier, sub system and condition monitoring devices amongst others. The lubricating oil system for a tug boat whose transmitting power is about 955KW was calculated mathematically to obtain the flow rate of the shaft line bearing cooling oil, stern tube bearing cooling oil, main engine camshaft bearing cooling oil and main engine camshaft bearing cooling oil. Modelled equations were employed to obtain the camshaft lube-oil pump capacity, surface area and storage tank. The cylinder lube-oil storage and density tanks were estimated to be 1m 3 while the transfer pump is calculated to be approximately 0.4m 3 /hr. The various suction and discharge diameters and velocities of pumps in the lubricating oil system were determined; it was observed the suction pipe diameter is always bigger than the discharge pipe diameter while the discharge velocity is higher than the suction velocity for all the pumps including the camshaft lube-oil pump, cylinder oil transfer pump and main lube-oil transfer pump. This is a clear indication that the said design process met the international standard for the design of such a tug boat. Similarly the shaft line bearing cooling oil pipe, piston bearing cooling oil pipe and main engine lube-oil pipe discharge velocities were seen to be at the acceptable limits obeying the classification rules. All designs were done in accordance to the Lloyd's specification rules and regulations for a sea going tug boat.

WATER-DIESEL EMULSION: A REVIEW

This reduction has been enforced by the legislating organizations around the world that gradually have made the manufacturers transform their engines to today's complex high‐tech products. One of the most challenging area to meet the legislations is the emissions of the diesel engines which are the products of the combustion of diesel fuel. More restrictions have been imposed by some governments to reduce these emissions to a level such that will not cause any harmful impacts for the environment after releasing them to the atmosphere. This paper examines the effects of combusting a mixture of diesel fuel, water, and surfactant which forms emulsion on the nitrogen oxides NOx, carbon monoxide CO, carbon dioxide CO2, sulfur oxides SOx emissions and particulate matter (PM) from a compression ignition (CI) or diesel engine. Previous research has attributed the observed reduction of these emissions to a suppression of the flame temperature due to quenching effects from the water, thereby reducing thermal NOx formation and other pollutants. The focus of this review paper will be on experiments were previously conducted using a diesel engine with pure diesel fuel and compare it to the emulsion of water-diesel. Furthermore, results from the testing diesel fuel that mixed with varied ratios of water balanced with a surfactant to stabilize the emulsion will be presented and discussed. Three different samples of water-diesel emulsion were used with 10 % water and 90 % diesel, 20 % water and 80% diesel, and 30 % water and 70 % diesel (by volume) respectively to conduct the experiments in the lab. The purpose was to see the impact of adding the water from 10 % up to 30 % (by volume) to the diesel fuel making the emulsified fuel to investigate the impacts on the emissions and the performance of the engine. The data shows a significant NOx emission reduction when using the emulsion water diesel fuel in the range from 20% to 30 % water (by volume) in diesel. These results are correlated with a thermodynamic first law analysis to estimate the adiabatic flame temperature of the standard fuel and fuel-water emulsion cases. Results indicate that thermal NOx is indeed reduced by quenching and flame temperature suppression confirming reports in the literature. Recommendations are given for further studies, including improving the fuel—water emulsion and considerations for long-term testing.

It is proved to be NP-hard and has several hard and soft constraints. A given set of events, class-teacher meetings and resources are assigned to the limited space and time under hard constraints which are strictly followed and soft constraints which are satisfied as far as possible. The feasibility of timetable is determined by hard constraints and the soft constraints determine its quality. Difficult combinatorial optimization problems are frequently solved using Genetic Algorithm (GA). We propose Partial Feasibility Preserving Genetic Algorithm (PFP-GA) combined with tabu search to solve hdtt4, " hard timetabling " problem a test data set in OR-Library. The solution to this problem is zero clashes and maintaining teacher's workload on each class in given venue. The modified GA procedures are written for intelligent operators and repair. The PFP-GA in association with Tabu Search (TS) converges faster and gives solution within a few seconds. The results are compared to that of using different methodologies on same data set.

Like other types of structures, they are susceptible to various types of defect and damage such as cracking, corrosion, chemical attack and time-dependent material degradation, which may impair their structural integrity and affect their service life. The presence of cracks in a cylindrical structure can considerably affect its behavior. The effects of these imperfections on load carrying capacity and safety are thus important considerations in the design of cylindrical shell structures. This present work presents a finite element study on the vibration, buckling and fracture behavior of a cracked cylindrical shell with clamped type supports and subject to a time varying rotating speed. Vibration, linear elastic buckling and fracture parameters of a cracked cylindrical shell with time-varying rotating speed are analyzed. The effects of constant rotating speed, crack length and orientation of crack and length-diameter ratio of the cylindrical shell on the free-vibration and buckling behaviors are investigated.

It is based on generating all partial products and their sum in one step. The implementation is done using cadence Virtuoso tool. The power dissipation of 8x8 bit Vedic multiplier obtained after synthesis is compared with conventional multipliers such as Wallace tree and array multipliers and found that the proposed Vedic multiplier circuit seems to have better performance in terms of power dissipation.

EXPERIMENTAL STUDY ON THE ANALYSIS OF HEAT ENHANCEMENT IN CORRUGATED TWISTED PIPES

The major challenge in designing a heat exchanger is to make the equipment more compact and achieve a high heat transfer rate using minimum pumping power. In recent years, the high cost of energy and material has resulted in an increased effort aimed at producing more efficient heat exchange equipment. Furthermore, as a heat exchanger becomes older, the resistance to heat transfer increases owing to fouling or scaling. The heat transfer rate can be improved by introducing a disturbance in the fluid flow thereby breaking the viscous and thermal boundary layer. However, in the process pumping power may increase significantly and ultimately the pumping cost becomes high. Therefore, to achieve a desired heat transfer rate in an existing heat exchanger at an economic pumping power, several techniques have been proposed in recent years and are discussed under the classification section. In this work, a study of transient heat transfer in double tube heat exchanger has enhanced. The inner tube of the setup was made with corrugation on both inner and outer walls by twisting the pipe from one end, which gives the more swirling motion to the fluid particles flowing over it. The flow inside the pipe was considered as turbulent, and the analysis was done experimentally and theoretically by using the ANSYS workbench. The experimental results were compared with the experimental values taken in the setup done by considering the inner tube as normal pipe. In both heat exchangers the values were taken and compared with the theoretical analysis. Temperature distribution and heat transfer rate were calculated and the details of the study have been discussed in this paper.

Since we do not know the exact details of loads [4] acting on a structure at any time, there is always some uncertainty about the total loads on structure. Thus random variables (means stochastic variable) of loads and other parameters are the main criteria of design variables [18]. They vary with space and time. The input variables is never certain and complete. The safety factor provided in the existing codes and standers primarily based on practice, judgment and experience, may not be adequate and economical. Using the techniques presented earlier, we can design or analyze individual members in the contest of structural reliability [2][3][22][24]. However we are not examined how the system performs [23] or how to calculate the reliability of the structure as a whole.

Finite Volume Method (FVM) with 3D Volume of Fluid (VOF) model has been used to formulate/simulate the complex interface in multiphase flow. The effect of important factors which govern the drop dynamics on a solid surface (like fluid properties: density, surface tension, viscosity and the surface characteristics: surface material, contact angle, roughness) have been studied extensively. Effects of shear strength in terms of air inlet velocity and drop size have also been studied by varying the Reynolds number of inlet air flow and drop volume respectively. Phase contours at different time instant have been produced for each of the case study. Again, the velocity contours and velocity vectors have also been generated for better understanding of the present phenomena. The acquired velocity by the droplet at different time instants has been calculated and the variation of the acquired velocity with time instants is plotted. Again it has been observed that depending upon various boundary conditions and external effects, it may possible to move the drop in any desired direction as per the requirement in various engineering applications like micro pumps, printers, coating devices etc.

If the object is video then the name given to this technique is video watermarking. The information which is hidden in the object and isn't seen by anyone then it is called as an invisible watermarking. In this paper, we are using the LSB, SS (Spread Spectrum) and DWT technique for embedding the information into the video and also work on the rational distortion. Today distortion is the biggest problem. This distortion can be destroyed the hide information. The reason of distortion is transmission channel, hackers, viruses etc. In my proposed work, we are working on the rational 6 th order model distortion. We are finding the PSNR, SSIM (Structural similarity index measure), Correlation, BER (Bit Error Rate), MSE (Mean Square Error) parameters for the distorted watermarked video and also detects the watermark (hide) information from the distorted watermarked video.

Over the last decade, micromachining technology has been increasingly used for the development of highly efficient cooling devices called heat sink because of its undeniable advantages such as less coolant demands and small dimensions. One of the most important micromachining technologies is micro channels. Hence, the study of fluid flow and heat transfer in micro channels which are two essential parts of such devices, have attracted more attentions with broad applications in both engineering and medical problems. Heat sinks are classified into single-phase or two-phase according to whether boiling of liquid occurs inside the micro channels The microchannel heat sink is designed for electronic chips that could be effectively cooled by means of forced convection, by water flowing through the microchannels. This project presents a Computational Fluid Dynamics (CFD) flow simulation modeling, where water is made to flow across different cross-sectional microchannel heat sinks placed on heat source. The flow simulation of water and convective heat transfer are carried by using commercial software " Solid Works Flow Simulation ". In the CFD process stacked microchannels of various cross-sections viz., rectangular, triangular, pentagonal and circular are designed, then by defining the computational domain, boundary conditions as inlet mass flow (1e-5 kg/s),outlet pressure (static pressure) and heat flux(750w/cm2) and by considering the parallel and counter flow direction of water in different cross-sectional microchannels the temperature drop in heat sink, pressure drop across the channels and amount of volumetric heat transfer coefficient are analyzed and compared.

Experimental works were conducted to investigate the effect of Copper-Oxide (CuO) nanoparticles volume concentration and the operating temperatures on the rate of Nano fluids heat transfer in a radiator heat Exchanger. CuO nanoparticles were mixed with the base fluid water and also Sodium Lauryl Sulphate (SLS) powder was added to enhance the mixing process and stabilize the dispersion of the Nano fluids. Experimental runs were conducted at varying operating temperatures which include that, CuO-water at different temperature such as 40℃, 50℃, 60℃, 70℃, 75℃, 78℃, 80℃, 83℃. Among the operating temperatures selected for study 80℃, gives the best performance in heat transfer and the convection heat transfer coefficient. The results of the current work generally indicate that Nano fluids have the potential to enhance the heat transfer of a compact heat exchanger. Results indicate that, best overall heat transfer coefficient for the radiator is obtained at a hot fluid inlet temperature of 80℃, and at a flow rate of 0.075kg/sec.

Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks. Using cloud-powered technologies means you need to provide your service provider with access to important business data. Meanwhile, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in procuring and accessing cloud services can also give nefarious users the ability to scan, identify and exploit loopholes and vulnerabilities within a system. For instance, in a multi-tenant cloud architecture where multiple users are hosted on the same server, a hacker might try to break into the data of other users hosted and stored on the same server. The following paper deals with the service models of cloud computing along with types of cloud computing & characteristics of cloud. Further challenges and security issues in cloud computing is also discussed and at last conclusion and future demand for research in the field of cloud computing.

Ethanol blends E5, E10, E15, E20, E22 were tested and found considerable reductions in the pollutant levels of CO, CO2, HC. The results indicate better combustions in petrol engine with ethanol blends. The reductions in HC and CO were to the extent of 80% to 90% compared to pure petrol fuelled IC engine.

WATER-DIESEL EMULSION: A REVIEW

Due to its impact on human health and the nature surrounding us, diesel engine emissions have bee... more Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organizations around the world that gradually have made the manufacturers transform their engines to today's complex high‐tech products. One of the most challenging area to meet the legislations is the emissions of the diesel engines which are the products of the combustion of diesel fuel. More restrictions have been imposed by some governments to reduce these emissions to a level such that will not cause any harmful impacts for the environment after releasing them to the atmosphere. This paper examines the effects of combusting a mixture of diesel fuel, water, and surfactant which forms emulsion on the nitrogen oxides NOx, carbon monoxide CO, carbon dioxide CO2, sulfur oxides SOx emissions and particulate matter (PM) from a compression ignition (CI) or diesel engine. Previous research has attributed the observed reduction of these emissions to a suppression of the flame temperature due to quenching effects from the water, thereby reducing thermal NOx formation and other pollutants. The focus of this review paper will be on experiments were previously conducted using a diesel engine with pure diesel fuel and compare it to the emulsion of water-diesel. Furthermore, results from the testing diesel fuel that mixed with varied ratios of water balanced with a surfactant to stabilize the emulsion will be presented and discussed. Three different samples of water-diesel emulsion were used with 10 % water and 90 % diesel, 20 % water and 80% diesel, and 30 % water and 70 % diesel (by volume) respectively to conduct the experiments in the lab. The purpose was to see the impact of adding the water from 10 % up to 30 % (by volume) to the diesel fuel making the emulsified fuel to investigate the impacts on the emissions and the performance of the engine. The data shows a significant NOx emission reduction when using the emulsion water diesel fuel in the range from 20% to 30 % water (by volume) in diesel. These results are correlated with a thermodynamic first law analysis to estimate the adiabatic flame temperature of the standard fuel and fuel-water emulsion cases. Results indicate that thermal NOx is indeed reduced by quenching and flame temperature suppression confirming reports in the literature. Recommendations are given for further studies, including improving the fuel—water emulsion and considerations for long-term testing.

It is proved to be NP-hard and has several hard and soft constraints. A given set of events, class-teacher meetings and resources are assigned to the limited space and time under hard constraints which are strictly followed and soft constraints which are satisfied as far as possible. The feasibility of timetable is determined by hard constraints and the soft constraints determine its quality. Difficult combinatorial optimization problems are frequently solved using Genetic Algorithm (GA). We propose Partial Feasibility Preserving Genetic Algorithm (PFP-GA) combined with tabu search to solve hdtt4, " hard timetabling " problem a test data set in OR-Library. The solution to this problem is zero clashes and maintaining teacher's workload on each class in given venue. The modified GA procedures are written for intelligent operators and repair. The PFP-GA in association with Tabu Search (TS) converges faster and gives solution within a few seconds. The results are compared to that of using different methodologies on same data set.

Like other types of structures, they are susceptible to various types of defect and damage such as cracking, corrosion, chemical attack and time-dependent material degradation, which may impair their structural integrity and affect their service life. The presence of cracks in a cylindrical structure can considerably affect its behavior. The effects of these imperfections on load carrying capacity and safety are thus important considerations in the design of cylindrical shell structures. This present work presents a finite element study on the vibration, buckling and fracture behavior of a cracked cylindrical shell with clamped type supports and subject to a time varying rotating speed. Vibration, linear elastic buckling and fracture parameters of a cracked cylindrical shell with time-varying rotating speed are analyzed. The effects of constant rotating speed, crack length and orientation of crack and length-diameter ratio of the cylindrical shell on the free-vibration and buckling behaviors are investigated.

A conventional multiplier consumes more power. This paper presents a low power 8 bit Vedic Multiplier (VM) based on Vertically & Crosswise method of Vedic mathematics, a general multiplication formulae equally applicable to all cases of multiplication. It is based on generating all partial products and their sum in one step. The implementation is done using cadence Virtuoso tool. The power dissipation of 8x8 bit Vedic multiplier obtained after synthesis is compared with conventional multipliers such as Wallace tree and array multipliers and found that the proposed Vedic multiplier circuit seems to have better performance in terms of power dissipation.

EXPERIMENTAL STUDY ON THE ANALYSIS OF HEAT ENHANCEMENT IN CORRUGATED TWISTED PIPES

The major challenge in designing a heat exchanger is to make the equipment more compact and achieve a high heat transfer rate using minimum pumping power. In recent years, the high cost of energy and material has resulted in an increased effort aimed at producing more efficient heat exchange equipment. Furthermore, as a heat exchanger becomes older, the resistance to heat transfer increases owing to fouling or scaling. The heat transfer rate can be improved by introducing a disturbance in the fluid flow thereby breaking the viscous and thermal boundary layer. However, in the process pumping power may increase significantly and ultimately the pumping cost becomes high. Therefore, to achieve a desired heat transfer rate in an existing heat exchanger at an economic pumping power, several techniques have been proposed in recent years and are discussed under the classification section. In this work, a study of transient heat transfer in double tube heat exchanger has enhanced. The inner tube of the setup was made with corrugation on both inner and outer walls by twisting the pipe from one end, which gives the more swirling motion to the fluid particles flowing over it. The flow inside the pipe was considered as turbulent, and the analysis was done experimentally and theoretically by using the ANSYS workbench. The experimental results were compared with the experimental values taken in the setup done by considering the inner tube as normal pipe. In both heat exchangers the values were taken and compared with the theoretical analysis. Temperature distribution and heat transfer rate were calculated and the details of the study have been discussed in this paper.

Since we do not know the exact details of loads [4] acting on a structure at any time, there is always some uncertainty about the total loads on structure. Thus random variables (means stochastic variable) of loads and other parameters are the main criteria of design variables [18]. They vary with space and time. The input variables is never certain and complete. The safety factor provided in the existing codes and standers primarily based on practice, judgment and experience, may not be adequate and economical. Using the techniques presented earlier, we can design or analyze individual members in the contest of structural reliability [2][3][22][24]. However we are not examined how the system performs [23] or how to calculate the reliability of the structure as a whole.

Finite Volume Method (FVM) with 3D Volume of Fluid (VOF) model has been used to formulate/simulate the complex interface in multiphase flow. The effect of important factors which govern the drop dynamics on a solid surface (like fluid properties: density, surface tension, viscosity and the surface characteristics: surface material, contact angle, roughness) have been studied extensively. Effects of shear strength in terms of air inlet velocity and drop size have also been studied by varying the Reynolds number of inlet air flow and drop volume respectively. Phase contours at different time instant have been produced for each of the case study. Again, the velocity contours and velocity vectors have also been generated for better understanding of the present phenomena. The acquired velocity by the droplet at different time instants has been calculated and the variation of the acquired velocity with time instants is plotted. Again it has been observed that depending upon various boundary conditions and external effects, it may possible to move the drop in any desired direction as per the requirement in various engineering applications like micro pumps, printers, coating devices etc.

If the object is video then the name given to this technique is video watermarking. The information which is hidden in the object and isn't seen by anyone then it is called as an invisible watermarking. In this paper, we are using the LSB, SS (Spread Spectrum) and DWT technique for embedding the information into the video and also work on the rational distortion. Today distortion is the biggest problem. This distortion can be destroyed the hide information. The reason of distortion is transmission channel, hackers, viruses etc. In my proposed work, we are working on the rational 6 th order model distortion. We are finding the PSNR, SSIM (Structural similarity index measure), Correlation, BER (Bit Error Rate), MSE (Mean Square Error) parameters for the distorted watermarked video and also detects the watermark (hide) information from the distorted watermarked video.

Over the last decade, micromachining technology has been increasingly used for the development of highly efficient cooling devices called heat sink because of its undeniable advantages such as less coolant demands and small dimensions. One of the most important micromachining technologies is micro channels. Hence, the study of fluid flow and heat transfer in micro channels which are two essential parts of such devices, have attracted more attentions with broad applications in both engineering and medical problems. Heat sinks are classified into single-phase or two-phase according to whether boiling of liquid occurs inside the micro channels The microchannel heat sink is designed for electronic chips that could be effectively cooled by means of forced convection, by water flowing through the microchannels. This project presents a Computational Fluid Dynamics (CFD) flow simulation modeling, where water is made to flow across different cross-sectional microchannel heat sinks placed on heat source. The flow simulation of water and convective heat transfer are carried by using commercial software " Solid Works Flow Simulation ". In the CFD process stacked microchannels of various cross-sections viz., rectangular, triangular, pentagonal and circular are designed, then by defining the computational domain, boundary conditions as inlet mass flow (1e-5 kg/s),outlet pressure (static pressure) and heat flux(750w/cm2) and by considering the parallel and counter flow direction of water in different cross-sectional microchannels the temperature drop in heat sink, pressure drop across the channels and amount of volumetric heat transfer coefficient are analyzed and compared.

Experimental works were conducted to investigate the effect of Copper-Oxide (CuO) nanoparticles volume concentration and the operating temperatures on the rate of Nano fluids heat transfer in a radiator heat Exchanger. CuO nanoparticles were mixed with the base fluid water and also Sodium Lauryl Sulphate (SLS) powder was added to enhance the mixing process and stabilize the dispersion of the Nano fluids. Experimental runs were conducted at varying operating temperatures which include that, CuO-water at different temperature such as 40℃, 50℃, 60℃, 70℃, 75℃, 78℃, 80℃, 83℃. Among the operating temperatures selected for study 80℃, gives the best performance in heat transfer and the convection heat transfer coefficient. The results of the current work generally indicate that Nano fluids have the potential to enhance the heat transfer of a compact heat exchanger. Results indicate that, best overall heat transfer coefficient for the radiator is obtained at a hot fluid inlet temperature of 80℃, and at a flow rate of 0.075kg/sec.

Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks. Using cloud-powered technologies means you need to provide your service provider with access to important business data. Meanwhile, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in procuring and accessing cloud services can also give nefarious users the ability to scan, identify and exploit loopholes and vulnerabilities within a system. For instance, in a multi-tenant cloud architecture where multiple users are hosted on the same server, a hacker might try to break into the data of other users hosted and stored on the same server. The following paper deals with the service models of cloud computing along with types of cloud computing & characteristics of cloud. Further challenges and security issues in cloud computing is also discussed and at last conclusion and future demand for research in the field of cloud computing.
