Evaluation of Cost Effective Material for Maintenance of Flexible Pavement
-Mr. Vikram D. Deshmukh ; Prof. G. N. Kanade
Roads represent an important infrastructure facility in all countries. Two important parameters for good pavements are pavement design and materials. A good design of bituminous mix is expected to result in a mix which is adequately strong, durable and at the same time environment friendly and economical in order to maintain the pavement. This work is undertaken to prepare cost effective material for maintenance of flexible pavement, by using industrial wastes such as steel slag and foundry sand as a replacement material for fine aggregate in bituminous mix and ground granulated blast furnace slag as a replacement material for fillers in bituminous mix. Fillers play an important role in engineering properties of bituminous paving mixes. Conventionally stone dust, cement and lime are used as filler play an important role in engineering properties of bituminous paving mixes. Conventionally stone dust, cement and lime are used as fillers. Now-a-days disposal of different wastes produced from different Industries is a great problem. These materials pose environmental pollution in the nearby locality because many of them are non-biodegradable. In recent years, applications of industrial wastes have been considered in road construction with great interest in many industrialized and developing countries. The use of these materials in road making is based on technical, economic, and ecological criteria. India has a large network of industries located in different parts of the country and many more are planned for the near future. Several million metric tons industrial wastes are produced in these establishments. If these materials can be suitably utilised in highway construction, the pollution and disposal problems may be partly reduced. Keeping in mind the need for bulk use of these solid wastes in India, it was thought expedient to test these materials and to develop specifications to enhance the use of these industrial wastes in road making, in which higher economic returns may be possible. The possible use of these materials should be developed for construction of low-volume roads in different parts of our country. Read More...

ANSYS of the Tata LPK 2518 Truck Chassis for Stresses and Weight Reduction using Fem Tool
-Gurlal Singh ; Zakir Hamid War
Chassis is one of the important parts that used in automobile industries. It is a rigid structure that forms a skeleton to hold all the major parts together. Chassis is a major component in a vehicle system. It should be rigid enough to withstand the shock, twist, vibration and other stresses. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, maximum stress, maximum equilateral stress and deflection are important criteria for the design of the chassis. This work involved Transient analysis to determine key characteristics of a chassis. The static characteristics include identifying location of high stress area. This paper presents the Transient load analysis of TATA LPK 2518 truck ladder chassis using ANSYS workbench and stress, Weight reduced by optimization in design. This has been carried out with limited modifications. We have taken Aluminium Alloy 6063-T6 for the chassis. Load applied on chassis is 9.26 N. The necessary design changes required to enhance the load carrying capacity of the vehicle has been recommended successfully. Read More...

Taguchi Based Optimization of Process Parameters for Friction Stir Welding of AA7075 and C11000
-Santosh N. Bodake ; Prof. Dr. A. J. Gujar
AA 7075 is an aluminium alloy, with zinc as the main alloying constituent. It has high strength, with similar to many steels, have good fatigue strength and average machinability, but has less resistance to corrosion than many other Al alloys. AA7075 are frequently used in transport applications such as marine, aviation and automotive due to their high strength to density ratio. Strength and light weight also desirable in fields such as Rock climbing equipment, bicycle components and airframes are commonly made from 7075 aluminium alloy. AA 7075 has low weldability due to reduced solidification microstructure, and when welded by fusion welding techniques go down its mechanical properties. Friction stir welding (FSW) is solid state, reliable joining techniques to retain the properties of the alloy as there is no melting of metal takes place, welding takes place due to the forging effect. As process parameter affects a lot on strength of joint so it is important to optimize process parameters. Process parameters for friction stir welding are tool pin profile, tool rotary speed, welding speed, and welding axial force, tool tilt angle and Tool shoulder. From above process parameters of FSW tool rotary speed, welding speed, and welding axial force effects most on mechanical strength. Current work deals with experimental investigation of optimization of friction stir welding process (FSW) to arrive at desirable mechanical properties of aluminum 7075 and C11000 plates. Responses recorded are Ultimate tensile strength, and hardness of weld zone. After conducting experimentation testing is done to measure ultimate tensile strength and micro Vickers hardness. Results are analysed in Minitab 16 for optimizing process parameters. Read More...

Experimental Study on Strength Characteristics of Self-Compacted Concrete with Polyethylene Glycol as a Self Curing Agent
-Srivathsa H U ; Sushma S; Yashwanth Kumar J; Varadaraj D R
With growing population, industrialization, and urbanization, there is corresponding growth in the demand for infrastructure. Insufficient compaction dramatically lowers ultimate performance of concrete in spite of good mix design. Placing the fresh concrete requires skilled operatives using slow, heavy, noisy, expensive, energy-consuming and often dangerous mechanical vibration to ensure adequate compaction to obtain the full strength of the hardened concrete. Self-compacting concrete (SCC) is an innovative concrete that does not requires vibration for placing and compaction. The performance of concrete depends on method of curing also. In conventional curing spraying of water/ keeping under wet condition is followed. A new technique called Self Curing (SC) which provides additional moisture in concrete for more effective hydration of cement. An attempt has been made to study the strength characteristics of M20 grade concrete by partially replacing cement with polyethylene glycol as self-curing agent in percentages of 0.5 to 2.

Effect of Non-Linear Soil Types on Seismic Response of Bridge Pier Supported on Well Foundation
-Abdullah Khan ; Rohit Rai
For both steel and RCC Bridges passing rivers or creeks, common practice in many countries is to provide concrete wells to support the bridge girders. For many bridges that are strategically important in terms of defense or trade, it is essential that they remain functional even after a strong earthquake hits the structure. The present state of the art for design of well foundation is still marred with a number of uncertainties where a simplistic pseudo static analysis of its response only prevails, though it is a well-known fact that load from super structure, character of soil and its stiffness plays an important role in defining its dynamic characteristics. The present paper is thus an attempt to present a dynamic analysis model trying to cater to a number of such deficiencies as cited above and also provide a practical model (amenable to design office application) that can be used to estimate the pier, well and soil's dynamic interaction.

-Elton Asher Jose Menezes ; Aniket Arvind Patil; Akash Chaware; Abid Ghori; Shreedatta Sawant
Weather is an important aspect of our human lives. Human can adapt to different climatic conditions but they also need to dress appropriately for them; so the weather conditions should be known to them. Weather Analysis using Twitter data aims to gather a series of Tweets based on a particular location and generate the weather condition/ conditions that the Tweets are making a reference to. An Unsupervised Learning Approach will be used in-order to automatically classify the Tweet/Tweets of a particular location into appropriate weather categories i.e. Sunny, Windy, Cold, Humid, Hot, Chilly, Cool. To achieve Unsupervised Learning Approach a Data Set will be given to a Classifier , like Naive Bayes/K-Nearest Neighbor in-order to determine which weather conditions the tweet or set of tweets belong to and also to help the classifier improve its accuracy in determining the correct output overtime. In order for classification, pre-processing steps will be carried out on the Tweet/Tweets obtained. The pre-processing steps consist of Removal of Stop Words, Removal of Hashtags, Removal of '@'symbol etc. The Steps will be explained in detailed throughout this document. Training of the Classifier involves having a set of Tweets that are already classified into the appropriate weather conditions. Once the Classifier has been trained; the test data is given to the classifier to determine the appropriate categories that the Tweet/Tweets fall under and what is the weather condition that the person/group of people belonging to that particular location are talking about.

Designing and Implementation of 9 Level Multi Level Inverter with IPD Topology
-Shantanu Khatri
The multi-level inverter system is very promising in ac drives, when both reduced harmonic contents and high power are required. A multilevel inverter is a power electronic system that synthesizes a desired output voltage from several levels of dc voltages as inputs. Recently, multilevel power conversion technology has been developing the area of power electronics very quickly with good potential for further developments. As a result, the mainly attractive applications of this technology are in the medium to high voltage ranges. Multi-Level Inverters (MLI) are today used in medium and great power applications. There are three major topologies of multi level inverters; they are capacitor clamped, diode camped and cascaded. Throughout this research work implement the nine-level asymmetric cascaded multi level inverter with IM for various kinds of level-shifted PWM techniques in Matlab Simulink. As the number of levels will augment, the synthesized output waveform has more steps that produce a staircase wave that approaches the required waveform. Also, as more steps are added to the waveform, the harmonic distortion of the output wave decreases, similar to zero as the number of levels will increase. As the number of levels will increase, the voltage that can be spanned near between devices serial also increases. Read More...

-Vrajesh Bhandari
The number of industry applications in which induction motors are fed by static frequency inverters is growing fast and, although much has already been done within this field, there is still a lot to be studied/ understood regarding such applications. The advance of variable speed drives systems engineering increasingly leads to the need of specific technical guidance provision by electrical machines and drives manufacturers, in this paper we have studied and developed a Simulink model with PWM inverter and find out the various characteristics and analysis them. This paper presents control of a three phase induction motor using single phase inverter with constant volts hertz control (V/F) method and pulse width modulation. Frequency control with flux proportional to V/f and voltage proportional to the speed seems to be the best solution. PWM gives a high quality output voltage. Single phase inverter output gives a better feed to the induction machine without extra components needed on the motor and also produces a higher starting torque and reduced speed pulsation amplitude.

An Approach to Image Enhancement using Discrete Wavelet Transform
-Ambesh Tiwari ; Shyam Shankar Dwivedi
Image enhancement helps in bettering the visibility of any part or feature of the image by improving the information in visual parts or features. Several techniques offer contrast regulation as a way which proves to be a cogent tool to improve the quality of an image. So image enhancement by applying various algorithms and techniques make an image individually looks better than the original image. This research work presents a novel DWT based image enhancement technique. The approach presented in this work is simple and robust and can be used to improve the perceptual visual quality of low resolution images. The images used in implementation are standard test images of 256x256 pixel values but of low visual perceptibility. The power log transformation evaluates the threshold value from the frequency (wavelet) transformed coefficients of the input image. This threshold values is used to transform the decomposition vector obtained from the 2-d multilevel wavelet decomposition. This modified vector is then reconstructed to obtain the enhanced image pixels. At last histogram equalization method is applied to improve the visual appearance of the image. The performance the algorithm has been evaluated using a Mean Square Error and Peak Signal to noise measures. The PSNR value is close to 40 db for almost all images which shows a good improvement over previous methods. Read More...

Tilting Angle Measurement of Wagon Tippler
-Mr. Santosh kumar Kushwaha
This paper proposed for tilting angle measurement of wagon tippler using absolute encoder in place of limit switch arrangement. The unloading cycle starts when the wagon is positioned over the tippler table, wagon along with the table rotates and discharges the material into the underground hopper. There wagon tipplers rotates about 0 to 180º. To measure the tilting angle an absolute encoder mounted on the rotating shaft. Absolute optical encoder rely on multiple light sources and photo detector assemblies, as well as code disks with segment patterns arranged as a series of annular rings. This code disk variant provides an absolute measurement by using a binary output to represent each individual shaft angle as the disk rotates between a radial arrangement of photo detectors and a linear sequence of light sources. The length of the rotational arcs for both opaque and transparent segments on the disk decrease based on their radial distance from the shaft. The accuracy of the shaft position generally depends on the quantity of the disk's annular rings, and as the disk rotates the light that passes through each ring produces a continuous signal stream. The electronics array then converts this stream of output into a binary code. Absolute encoders have code disks that retain the last angular position of the shaft from the point at which it stopped moving, even if the system shuts down. This provides a fail-safe by preserving data in case of power failure or malfunctions. Read More...

Fasteners used in Various Place on Steel Structure Elements
-Dr. Sanjeev Gill ; Dr. Rajiv Kumar
In this various elements of steel structure like tension member, compression member and flexural member are connecting by fasteners or connectors. Many a times, built-up sections are provided to meet the requirements of heavy loads and long spans. Such sections also need to be connected together to act in unison as one unit. The forces exerted by one element on another are transferred through these fasteners, which should therefore be adequate to transmit the forces safely. Only properly connected and detailed members and connections can transfer the forces safely from top to the foundation. Different types of fasteners available for making connections are rivets, bolts, pins and welds. Today, steel structures are constructed with bolting or welding or by combination of both. To simplify the analysis and design, a number of assumptions and approximations are made based on experimental results, past performance and ductility of steel. The ultimate aim of connection design is to produce a joint that is simple, compatible, feasible, easy to fabricate and is safe and economical. Read More...

-Pratik Prasad Kamat ; Punit Dilip Korgaonkar; Rachana Rajan Mulik; Chinmay Pradeep Pednekar; Tejas Kiran Pathak
In the current internet community, due to attack made on data communication secured data transfer is limited. Hence data hiding method such as steganography is chosen which ensures secured data transfer. However, existing steganographic systems have become more predictable, have a limit on length of secret message for a given cover file which opens door for advanced techniques such as audio steganography. Limitation of current steganographic system is that, if the method used is deduced by attacker then extraction of secret message may be known. Therefore, the proposed system uses steganography along with cryptographic approach to make data more secure such that even if the steganographic method is deduced by attacker, it would still be in encrypted form.

Various Effect of Foam Concrete other than Ordinary Concrete
-Dr. Sanjeev Gill ; Dr. Rajiv Kumar
In this paper the Foam concrete is a type of aerated lightweight concrete; foam concrete does not contain coarse aggregate and canbe regarded as an aerated mortar. Foam concrete is produced when pre-formed foam is added to slurry, the function of foam is to create an air voids in cement–based slurry. Foam is generated separately by using foam generator; the foaming agent is diluted with water and aerated to create the foam. The cement paste or slurry set around the foam bubbles and when the foam being to degenerate, the paste has sufficient strength to maintain its shape around the air voids. The foam concrete mixture becomes too stiff with lower content, causing bubbles to break, whereas the mixtures becomes too thin to hold the bubbles with high water content, leading to the separation of bubbles from the mixture, water-cement (w/c) ratio usually ranges from 0.4–1.25. Foam concrete can be designed to have any density within the dry density range of 300–1850 kg/m3. In this investigation two foam concrete mixtures are produced with and without sand and attempts have been made for selecting the proportions of foam concrete mix for the target plastic density of 1900 kg/m3. 18 cube specimens are prepared and tested for mixtures, then their physical as well as specific structural properties were investigated, Specific Strength concrete and the results are reported.

Analysis and Simulation of Variable Frequency Measurement for Induction Motor
-Vrajesh Bhandari
Induction motors and Variable Frequency Drives (VFDs) are widely used in industry to drive machinery trains. However, some mechanical trains driven by VFD motor systems have encountered torsional vibration problems. This vibration can induce large stresses on shafts and couplings, and reduce the lifetime of these mechanical parts. Long before the designed lifetime, the mechanical train may encounter failure. This thesis focuses on VFDs with voltage source rectifiers for squirrel-cage induction motors of open-loop Volts/Hertz and closed-loop Field Oriented Control (FOC). Induction motor loss segregation and efficiency measurement requires loading dynamometers and other equipment such as a variable voltage sinusoidal power supply. These are expensive and not often available even when a loading device is accessible. Variable frequency drives are now widely used for operating induction machines and are more widely available and less expensive. Read More...

Design and Fabrication of Wooden Lathe Machine
-Suraj Srivastava ; Vaibhav Singh
Lathe machine is one of the most versatile and widely used machine tool all over the world. It is commonly known as Mother of all Machines. An engine lathe is the most basic and simplest form of the lathe. It derives its name from the early lathes, which obtained their power from engines. Besides the simple turning operation, lathe can be used to carry out other operations also, such as drilling, reaming, boring, taper turning, knurling, screw thread cutting, grinding etc. The Light Weight (wood) lathe machine is introduced to lessen the human suffering and to improve economic and technological standard, and for years Nigeria recognized that she was economically and technological poor and has been economically dependents on the western world for survival in terms of technology. To discourage this importation of technological equipment placed embargo on the importation of certain goods and this inspired our people to recognized indigenous technology though our fore father used axe, cutlass and some other sharp tools from designing woods. It is the acknowledgement of this fact that led to the design of wood lathe machine, even though this project of design and fabrication of Light Weight Lathe machine is a copied design, we tried to improve more on this machine so that it can design wood with little or no stress, utilizing the available material in order to reduced cost for production purposes and durability.

-Mr. Bhagvat A. Wadekar ; Prof. Mr. Rohan Katwate; Prof. Mr. Avinash S. Patil; Ms. Punam M. Chabukswar
This Paper is about the analysis of Cyclone separator for Spray Dryer with improved design. Industrial spray dryers are used to convert the sludge product into powder form. The size of powder product is in the range of microns and it is necessary to separate the powder from process air. Cyclone, Bag filter and Scrubber are most widely used devices in particle separation process. The cost of bag filter and scrubber is approximately three times that of cyclone. Hence by improving the efficiency of cyclone, the load on Bag filter and Scrubber can be reduced. The primary objective of the present study was to analyze the cyclone separator theoretically and CFD analysis. The second objective was to propose a new design of cyclone which will have greater efficiency than the existing design cyclone. The present cyclone was analyzed in ANSYS Fluent. The results from theoretical and CFD analysis were compared. The second objective was achieved by introducing an invert cone at bottom part. CFD analysis was carried out using the same procedure as mentioned in the case of previous analysis. The trajectory of the particle, flow path of the gas and the drop in pressure were analyzed. The theoretical collection efficiency of the existing cyclone separator was found to be 94.2 %. The efficiency of the existing cyclone from CFD analysis is found to be 95.7 %. The variation in theoretical and CFD results was found to be 7%. The pressure drop in the proposed cyclone separator from CFD analysis is found to be increase by 5 mmwc compare with the CFD results of present cyclone separator. The efficiency of proposed cyclone was found to be 98%. Thus the proposed cyclone separator is 2% more efficient than present cyclone separator. Read More...

Attribute-Based Encryption Access Control Scheme in Cloud
-Mr. Prashant B. Patil ; Prof. Amruta O. Deshmukh
Cloud computing refers to the practice of transitioning computer services such as computation or data storage to multiple redundant offsite locations available on the Internet, which allows application software to be operated using internet-enabled devices. Clouds can be classified as public, private, and hybrid. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centres. It relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Since the cloud computing environment is distributed and untrusted, data owners have to encrypt outsourced data to enforce confidentiality. To achieve practicable access control of encrypted data in an untrusted environment is an urgent issue that needs to be solved. Attribute-Based Encryption is a promising scheme suitable for access control in cloud storage systems. This system proposes a hierarchical attribute-based access control scheme with constant-size cipher text. Read More...

-Shashank Dewangan ; Dr. S. K. Ganguly; Dr. R. Banchhor
Aluminium Hybrid Composites are the new group of metal matrix composites (MMCs) due to their attractive properties like high ductility, high conductivity, light weight and high strength to weight ratio and is a response to the dynamic ever-increasing demand of these super material in the field of aircrafts and marines. Carbon Nanotube (CNTs) are also known for their high strength and stiffness and their low density which when combined together makes CNTs an ideal reinforcement. This work briefly reviews the research revelation of an Aluminium (Al-6061, 99% pure) based hybrid metal matrix composite reinforced with CNTs and TiO2. The Hybrid Aluminium Metal Matrix Composites (AMMCs) is prepared with various CNTs weight percentages (0, 0.5, 1 and 1.5 wt. %) and keeping TiO2 weight percentage fixed to 1%.Stir Casting (SC) is focused in general to successfully fabricate the MMCs. The discussion of this work revolves around tensile test, hardness test, and Scanning Electron Microscope (SEM) of the MMC. The mechanical properties of the fabricated MMCs materials like tensile strength, hardness and impact strength is found by using these experimental methods. It has been observed that the tensile strength of the MMCs increases in the presence of TiO2 and CNTs and increases even more with the increase in the weight fraction of CNTs. Same results have been obtained for hardness and impact strength where there is an increase in them in the presence of TiO2 and CNT and their value increases even further with increase in weight fraction of CNTs.

Effect of Various Polyethylene Glycolon the Compressive and Split-Tensile Strength of Self-Curing Concrete
-Manu Vijay ; Navien S; Sowmyashree C; Harshitha S; Ashok Kumar
Curing of concrete is the process involved in maintaining satisfactory moisture content and maintain favourable temperature for hydration in concrete so as to develop the desired properties of concrete. However, perfect curing is not always possible in all cases. Self-curing concrete is the type of concrete that can cure itself with its retained moisture content. It is prepared with the addition of certain chemicals as self-curing agents. Earlier works conducted on self-curing concrete have indicated that these types of concretes have better strength, reduces rate of evaporation from surface, thermal properties, fire resistance, skid-resistance property improves, reduction in autogenous shrinkage, reduced chloride ion penetrability, improvement in freezing and thawing durability as well as the contact zone between aggregate and cement matrix and reduction in micro-cracking which results in better elastic compatibility compared to conventionally cured concretes. In this project work, the individual effect of curing agents like PEG 400, PEG 4000 & PEG 6000 on strength properties by varying the percentage by 0.5% and 1% were studied. The study shows that PEG 6000 with 0.5% could help in gaining maximum strength of curing. The test results showed that self-curing concrete is best option in places where water scarcity occurs.
