Abstract: This paper presents a study on behavior of short columns strengthened with GFRP techniques. Relatively recent materials like fiber reinforced polymers (FRP), have been used to strengthen circular short columns. Glass fiber external sheets were used in the circumferential direction to confine circular columns. Six specimens were tested under an axial load. The main concentric purpose of this study is to evaluate the effect of GFRP confining with different techniques in strengthening deficient columns (low compressive strength concrete). This study achieved comparison between GFRP strengthened columns (strips/jacket) and control columns. Two techniques were used external confinement, using external strips of GFRP wraps and GFRP jackets. Test results revealed that the two techniques enhances the axial load carrying capacity of the columns significantly for both reinforced and unreinforced specimens. Test results, comparisons and analysis are shown herein.

ABSTRACT: The fracture toughness is a critical material property that determines engineering performance. Because of the unique and distinctive mechanical properties of bulk Metallic glasses (BMGs), they have received substantial attention over a few decades. However, many of them exhibit poor plasticity because the deformation of these materials are highly confined to few shear bands. In this study, two kinds of bulk metallic glasses namely Cu-based and Zr-based Bulk Metallic Glass with no plastic strain are adopted as matrixes. Both of them were reinforced by crystalline TiNb with the same volume fraction and particle size. The data obtained by the loading tests showed that the plastic strain of Zr-based BMGCs was much higher than the Cr-based BMGCs. In this research we are relating changes in the plastic strain to the fracture toughness of the material. In the composite having high fracture toughness, the strength of the main crack is reduced due to the formation of micro-cracks on the surface of the specimen which simultaneously resulted in a large plastic strain in the Zr-based BMGCs. On the contrary, for the Cr based BMGCs, crack propagated rapidly throughout the volume, so no such micro-cracks were generated and thus the plastic strain generated in the latter was much less than the Zr-based BMGCs.

Abstract: As crimes are becoming more sophisticated and unrestricted in nature, there is a growing demand for better technology to fight crime. Technology to detect crime can be classified into 'hard' and 'soft' technology. This paper further explores the methods used in USA to prevent crime and whether if such methods will be adaptable in a developing country like India. India has a notorious reputation for being a popular heinous crime zone, a trend that is consistently on the rise. The current crime terrain necessitates the use of sophisticated technology to ensure public safety and crime prevention. Given this backdrop, the study emphasizes on the introduction of 'hard' and 'soft' technology to detect crime in India, through various primary and secondary data. I have adopted Delhi, as a sample city to study the crime patterns and provide suggestive theories and strategies that can be adopted to prevent crime.

ABSTRACT: Machine vision has been adopted in numerous industries since it eliminates need of human involvement and provides considerable accuracy along with splendid speed. Laser triangulation has brought a new era in measurement enabling measurement in third dimension. Still due to nonlinearities present in camera and laser sensor, it is difficult to apply this principle universally for large range of heights. In this regard, a piecewise linear calibration system is proposed in this paper. This system enables the sensor to cover considerably large working range with more precision. Actual set of objects are measured and readings are compared with respect to error and standard deviation.

Abstract: Polyvinyl chloride (PVC) is rated second only after poly ethylene (PE) as volume leader in the plastic industry. Waste PVC poses serious environmental problem because of its high chlorine content (56%) and non-biodegradable nature. Treatment of waste PVC by incineration or pyrolysis produces toxic chloro emissions which adversely affect environment, ecology and human health. Catalytic degradation of PVC was performed using a fluidized bed reactor with catalyst such as Fe2O3, ZSM-5, Pd/Aℓ2O3 in the temperature range 100 – 430°C. Arrangement was made to adsorb liberated chlorine on CaCO3. The effect of feed to catalyst ratio and temperature were evaluated for the maximum liquid yield. Maximum liquid yield of 12.17% was obtained using catalyst ZSM-5 at 3:1 feed to catalyst ratio.

Abstract: Automation in industries needs faster approach for object inspection. So, for such applications we generally go for machine vision. But, accuracy is also very important. Pixel accuracies are sometimes insufficient to describe the exact dimensions of an object or fall short. In such cases, there is an urgency to device a method which will take care of subpixel accurate measurements. Here, we have come up with such a novel approach to find subpixel accurate edges of a circular object. This we achieved by exploiting local pixel intensity values. Subpixel order of 20th was easily achieved i.e. measurements up to 20 times that of a pixel could be made. We achieved measurements up to 30 microns.

Abstract: This paper aims to improve the penetration of account holders in rural India for financial inclusion under the PradhanMantri Jan DhanYojana (PMJDY) by the mechanism of diversifying the already installed Automatic Teller Machine (ATM) which are underutilized in certain location of Urban area owing to less than optimum threshold of number of hits per day for sustainability & operation of ATMs resulting in huge financial loss to the bank and government infrastructure expenditure. Thus a mechanism has been devised to diversify the underutilized ATMs to such a location where installation of these ATM increases the convenience, confidence & penetration of account holders for people in rural India. Thus, different parameters of diversifying an ATM such as number of prospective account holders, potential area (location) and percentage of literacy rate were taken to analyze the installation of diversified machine which was earlier used in urban location resulting in identifying the optimum number and locations of ATM so as to ensure an equitable distribution of ATM within a geographic region in rural India.

ABSTRACT: Many organizations have installed wired linear networks as a part of communication within the organization and have always faced some kind of technical faults and these faults are needed to be detected easily. If any network fails or fault occurs in linear network, it causes to fail whole network system. To identify the fault occurred in linear network we need to check each network individually from the main server or backbone network to each network until we identify the fault or error. In the process of identification of fault or error all system remains in unused states. To check each network and solve the error in network is time consuming process as well as headache to the networking professionals. Our project will make it easier to notify the problems at the specific location and also will restore the whole network.

Abstract: Steganography is the method of hiding the message in a cover file. Modern methods of steganography are: Image Steganography, Audio Steganography, and Video Steganography. In this paper we are focusing on “Audio Steganography”.In Audio Steganography system, secret messages are embedded in digital sound. In this paper, the secret message is embedded by altering the least significant bit of a sound file. Audio Steganography software can embed messages in WAV, AU, and even MP3 formats. Our approach is to hide message in audio file by Least Significant Bit (LSB) insertion along with asymmetric key based RSA algorithm. The idea behind this paper is to enhance the security of information that has to be sending to receiver.

ABSTRACT: An emissions and performance study was performed to show the effects of injection pressure, nozzle hole inlet condition (sharp and rounded edge) and nozzle included spray angle on particulate, NOX, and BSFC. The Simulations were conducted on a fully instrumented single-cylinder version of the Caterpillar 3406 heavy duty engine at 75% and 25% load at 1600 RPM. Commercial validation tool FLUENT was used for numerical simulation. This tool solves the basic governing equations of fluid flow that is continuity, momentum, species transport and energy equation. Using finite volume method Turbulence was modeled by using standard k-έ model. Injection was modeled using LaGrangian approach. The reaction was modeled using non –premixed combustion which considers the effects of turbulence and detailed chemical mechanism into account to model the reaction rates. The specific heats for all the species was approximated by using piecewise polynomials. The fuel system consisted of an electronically controlled, common rail injection system with an injection pressure of 160 M Pa. Particulate versus NOX trade-off curves were generated for each case by varying the injection timing. The 75% load results showed the expected decrease in particulate and flattening of the trade-off curve with increased injection pressure. However, in going from 90 to 160 M Pa, the timing had to be retarded to maintain the same NOX level, and this resulted in a 1 to 2% increase in BSFC. The rounded edged nozzles were found to have an increased discharge coefficient. By adjusting the injection pressure, it was possible to compare the performance of the rounded and sharp edged nozzles with the same mass rate of injection profiles. Interestingly, the sharp edged nozzle gave significantly lower particulate emissions and lower BSFC at lower injection pressures. However, as the injection pressure was increased the difference in particulate became smaller and the rounded edged nozzles gave lower BSFC. Two nozzle spray angles with included angles of 125 and 140 degrees were studied. The effects of spray angle on particulate and NOX emissions were found to be small at high load, but differences were seen at light load. These results are interesting because the spray in the 125 degree case is directed so as to give significant spray impingement on the piston bowl wall, while the 140 degree nozzle has minimal wall impingement.

ABSTRACT: An experimental investigation has been done to vortex tube refrigeration set-up. The vortex tube is counter flow type which is being designed and fabricated. Vortex tube is a simple mechanical device used for the refrigeration as well as heating purpose. It uses a compressed gas which is being segregated into two streams of hot gas and cold gas at opposite ends. Here air is used as a working fluid. Various parameters affect the performance of Ranque-Hilsch vortex tube (RHVT). These parameters can be classified into two types viz. working parameters and geometrical parameters. The working parameters include inlet pressure of compressed air, cold mass fraction, ambient air temperature while the geometrical parameters includes diameters of nozzle, hot side and cold side, lengths of hot side and cold side, conical angle of valve. The effect of mentioned parameters is being discussed in this paper. UPVC (unplasticised polyvinyl chloride) material is being used as piping material since it has a very low thermal conductivity. The performance of vortex tube is being studied and investigated in this paper.

ABSTRACT: The effects of thermal processing methods and duration on some nutritional and anti-nutritional composition of African breadfruit seed (Treculia africana) flour were investigated. Matured African breadfruit seeds were sorted, washed and drained. The drained seeds were dehulled manually to obtain a full fat dehulled breadfruit seed. With the initial nutritional and anti-nutritional compositions determined, the samples were divided into three portions of 600g each of the breadfruit seed. The three portions were boiled, roasted and autoclaved respectively. The boiled and autoclaved samples were dried in an oven set at 60oC for 15mins. Similar quantity was left raw to serve as control. All samples were milled into flour of particle size 1mm mesh. The flours were analyzed for their nutritional and anti-nutritional composition using standard methods. The results showed that the raw sample contained 3.33%, 4.33%, 15.67%, 4.64%, 25.62% and 43.49% of moisture, ash, crude fat, crude fibre, crude protein and carbohydrate (CHO) respectively. It also contains 1.49mg/100g, 1.30TUI/mg, 32.03mg/100g, 2.07mg/100g, 4.00% and 3.24mg/100g of Hydrogen cyanide (HCN), Trypsin inhibitors, Tannin, Phytate, Alkaloids and Oxalate respectively. Boiling and autoclaving yield a better fat and CHO content, with boiling for 90mins having the highest fat content of 18.50%. Increase in thermal processing duration also resulted to a significant (P<0.05) decrease in crude fibre and ash content. Roasting was more effective in reducing moisture content as roasting for 90mins significantly (P<0.05) reduced moisture content to as low as 1.67%. There was a significant decrease (P>0.05) in anti-nutritional composition of the flour irrespective of the thermal processing methods and duration. Boiling and autoclaving for 90mins significantly (P<0.05) reduced hydrogen cyanide content to as low as 0.48mg/100g and 0.80mg/100g respectively and reduced phytate to 0.79mg/100g and 0.57mg/100g respectively. Statistically, no significant difference (P>0.05) was observed in the mean values of the boiled and autoclaved samples for tannins. It was concluded that either of the thermal processing methods used in the study can be used as a safe processing method for African breadfruit seed. Boiling or autoclaving of breadfruit seed prior consumption or conversion into flour is recommended in terms of increased nutrients and reduced anti-nutrients.

ABSTRACT: An estimated seventy percent of Indian economy depends on agriculture. Since there is growing Indian population, which is increasingly dependent on the agricultural yield, production of the crops must be enhanced. In order to grow more the diseases must be analysed in prior. Diseases are analysed using different image processing techniques. One such technique is proposed here. The proposed framework has been implemented in three phases. First, image segmentation is performed using K means clustering to identify the diseased regions area. In the next step features are extracted from segmented regions using feature extraction techniques such as GLCM. These feature are then used for classification into healthy or disease affected type. Experimental results of classification using Support Vector Machines show that our proposed technique is quite significantly better than any other existing techniques used for Plant Disease Detection and Identification and Support Vector Machines provides very accurate classification results.

ABSTRACT: Concrete is most widely used construction material in the world. However, it has low tensile strength, low flexural strength, low ductility and low energy absorption. An intrinsic cause of poor tensile behaviour of concrete is its low toughness and the presence of defects. Therefore to improve its strength, toughness and ductility fibres are used in concrete. Fibre reinforced concrete is a composite material consisting of cement based matrix with an ordered or random distribution of fibres. The addition of fibres increases the properties of concrete such as flexural strength, impact strength and shrinkage strength. In this present experimental work of investigation the main objective is to study the flexural strength of concrete using different fibres with same aspect ratio for all the fibres and to study the effect of alternate wetting and drying for 30 cycles on Flexural strength of concrete using different fibres such as steel fibre, glass fibre and Polyproplyene fibre with variation of fibre percentage from 0%, 1%, 1.5% and 2% and comparing their strength with 28 days strength of concrete without alternate wetting and drying. From the experimental investigation it is clearly observed that there is very good enhancement in flexural strength for all combinations of fibres and all percentage variation of fibres.

ABSTRACT: Wireless mesh networks (WMNs) are multi-radio, multi-hop networks with the ability of dynamically self configuring, self tuning, self-healing and self organizing. In WMN, transfer of data takes place to and from the access points (APs). Since wireless mesh networks are ad-hoc in nature, many routing protocols used for ad-hoc networks like AODV (Advanced on Demand Vector) are also used for WMNs by considering only the shortest route to destination. Data transfer through these protocols leads to congested routes and overloaded APs. Since, routing is a multi constraint problem. In order to reduce congestion and make routing decisions more reliable, routing decisions should be based on more than one constraint. For ensuring the route reliability, it is necessary to find out the route that lasts for longer time. This report is based on fuzzy logic, we have proposed a reliable routing scheme in order to obtain reliable route in WMNs. In this scheme for each node in wireless mesh network, we consider three parameters i.e. node residual energy, hop count and throughput. The proposed routing scheme maintains a reliable path from source to destination thus enhancing network life time and reduces number of packet loss during packet transmission. Simulation results indicate that proposed routing scheme has significant reliability enhancement as compared to other routing algorithms such as AODV. The simulation results show that the proposed routing scheme is effective and reliable.

ABSTRACT: A single phase multilevel inverter for dcto ac conversion is developed with minimum number of power electronic devices and isolated DC sources with implementation using FPGA. The total harmonics of the output waveform is reduced by increasing the switching modes with reduced devices. The H-Bridge multilevel inverter has two inverters connected in cascade. The proposed inverter can output more numbers of voltage levels in the same number of switching devices by using this conversion. The number of gate driving circuits is reduced, which leads to the reduction of the size and power consumption in the driving circuits. The total harmonic of the output waveform is also reduced. The proposed inverter is driven by the hybrid modulation method.The hybrid modulation algorithm is simulated using MATLAB/Simulink. The VHDL code for each of this topology was written and synthesized using Xilinx ISE software. Behavioral Simulation was performed on the architecture and after verifying the results this VHDL code was downloaded to SPARTAN 3A DSP board.

ABSTRACT: In the modern era of fast computing data storage and data retrieval is occurred due to cloud computing. Cloud computing is a pool of computing resources available on demand with the use of internet. it is a term used for the consumption of utility computing resources. it is used to maximize the effectiveness of the shared resources which is currently available on cloud. it relaxes the companies from investing money on heavy infrastructure rather they can used the same resources on shared basis..in the wide use of cloud computing threat comes to storage of data in the cloud server as it not known to the cloud user where there data will be stored they usually reluctant to store their data on cloud. to gain their trust cloud providers are facilitating various user confidentiality methods to stored their data..one technology is being used is data swapping. it is a strategy for protecting the micro data confidentially which is yet to be released. the purpose of data swapping is to create uncertainty in the minds of the intruder. it is a method to adjust the data values by swapping fraction of records between the records so that the intruder won't get the actual data rather gets scrambled data.
