In current decade, demand in material characteristics like light weight, superior strength to weight ratio, improved surface properties and enhanced wear resistance for complex engineering applications like automobile, aerospace and nuclear are researcher’s interest. However, performance of hybrid composites depends on right combination of reinforcements. Silicon carbide, silicon nitride, boron nitride and titanium carbide are few reinforcements available at present. In this work, Al356 is reinforced with SiC and B4C to enhance the mechanical properties, surface hardness and wear resistance. This hybrid composite is prepared by stir casting technique and the morphology of composite is studied using optical microscope to investigate the dispersion of reinforcements. In the present study, the wear and friction characteristics of hybrid composites are investigated using pin on disc dry wear tests by varying the load and speed and the results are tabulated for load vs mass loss, load vs wear rate and load vs wear coefficient. The results report that wear rate of hybrid composites are lower than that of binary composites. Mechanical properties, surface hardness and wear characteristics of aluminium hybrid composites are compared with that of aluminium binary composites available at present.
Aluminium Matrix Composites (AMC’s) are widely used in aerospace, automotive,
structural and marine applications due to their high strength to weight ratio, corrosion
resistance. In AMC one of constituent is aluminium or its alloy which forms a network
called as matrix phase and other constituent is embedded in matrix made of harder material
generally ceramic or non metallic material called as reinforcement. Various processing
techniques are available for manufacturing of AMC’s. Stir casting is one of the economical
and extensively used methods to enhance attractive properties of AMC’s. This paper
presents an overview of stir casing process, process parameter and preparation of AMC
using aluminium alloy as matrix phase and alumina (Al2O3) as reinforcement by varying
their proportion.

Evolution of automobile production has been driven by competitive materials. Light-weight alloys are
continuously developed as most sustainable for automotive sector. Aluminum is being used as a successful
material in automotive applications due to its low weight, higher strength, good corrosion resistance and
formability to suit different design requirements. Since aluminium has the potential to be used as replacement
of the current automotive materials like steel and cast iron, its demand has increased greatly. In a further
development aluminium metal matrix composites (MMCs) were developed and these have improved wear
resistance, high fatigue strength and better thermal stability, as compared with those of aluminum. In
automobile sector, wear is a major problem, specifically in engineering assemblies and materials used for this
purpose should have good tribological properties. To this effect Al MMCs have attracted significant attraction
since they have improved wear resistance. Metal matrix composites are usually produced with secondary
particles in the form of either continuous or discontinuous fiber or particles. From the viewpoint of good
mechanical properties aluminium matrix is generally reinforced by oxide or carbide, nitride or boride
ceramics (like Al2O3, SiC, Si3N4, TiC, TiB2. Reinforcement of the matrix with only one of these
reinforcements may not yield desired properties and the matrix may need to be augmented with other
reinforcements also. Graphite and SiC are the reinforcements used widely in automotive industries to achieve
better mechanical and tribological properties and dampen the vibrations with less operational costs.
Aluminum metal matrix composite can be produced by various methods including powder metallurgy,
conventional casting technology, etc. Among the casting methods semisolid processing of composites yields
better mechanical strength. This review deals with various manufacturing methods of metal matrix composites
processing and insight on semisolid processing and its process parameters.

INVESTIGATION ON WEAR RESISTANCE BEHAVIOR OF SIC FILLED HYBRID COMPOSITESIAEME Publication
Polymer composites and hybrid polymer composites are replacing many of the monolithic materials and alloys due to their higher strength to weight ratio, while apparently exhibiting excellent strength to corrosion and wear resistance. Investigation was carried out through experimental study on Silicon Carbide (SiC) filled, different combination of hybrid composites to determine the ‘two body’ abrasive wear behavior. Freshly fabricated Glass-Jute-Epoxy, Glass –Sisal-Epoxy and Glass-Rubber-Epoxy composites with different weight percentage of silicon carbide filler was subjected to two body abrasive wear test under normal room temperature in dry condition on pin-on-disc equipment using 300 grit SiC sand papers. Abrasive paper was stuck on to the rotating disc and test specimen was attached to the flat surface of the pin. The effect of filler content on the (0%,5%,10% ) was studied for 20N load for different sliding distance (25m,50m,75m,100m). The results reveal that the material with increases in filler content is prone to higher wear resistance. The polymer composites with 10% SiC showed least wear loss in all the combination under consideration and lowest wear loss was achieved in glass rubber epoxy and10% SiC combination.

Microstructure and tribological properties of Al-TiB2 nano surface composite fabricated by Friction Stir Processing (FSP) were evaluated. To vary the percentage of TiB2 three different slot thickness viz. 1mm, 1.5 mm and 2mm were considered. Microstructural evaluations showed a nearly uniform distribution of TiB2 in the aluminium matrix after FSP with the addition of composite powder. Microhardness test results shoes FSW of Al6061-T6 alloy with 2mm groove width has more hardness. tribological properties were evaluated at two different sliding velocities 0.314m/s and 0.48m/s and results shows that at lower loads there is no much difference in wear rate of surface composite made with different slot sizes but with increase in load and sliding velocity wear rate was increased , however, larger slot Al6061-TiB2 Surface composites show better wear resistance.
Characterization of Al/WC/Fly ash Metal Matrix Compositesijtsrd
Metal matrix composites are formed by combination of two or more materials (at least one of the materials is metal) having dissimilar characteristics. In this present investigation, aluminium (Al 6061) as base matrix metal and tungsten carbide (WC) particulate, fly ash as reinforcements. Fabrication of MMCs was done by stir-casting process. The Tungsten Carbide particulate was added in proportions of 1%, 2%, and 3% and Fly ash was added in proportions of 2%, 4%, and 6% on mass fraction basis to the molten metal. The different combination sets of composites were prepared. Mechanical properties like tensile strength and hardness were studied for both reinforced and unreinforced Al 6061 samples. Microstructure examination was carried by using Scanning Electron Microscope (SEM) to obtain the distribution of tungsten carbide particulate and fly ash in base matrix. From the results, it was found that the tensile strength and the hardness of the prepared metal matrix composites increased with increase in tungsten carbide and fly ash content. The Scanning Electron Micrographs of the samples indicated uniform distribution of tungsten carbide and fly ash particles in the base matrix without voids before testing and with voids after testing.

PEDESTRIAN DETECTION IN LOW RESOLUTION VIDEOS USING A MULTI-FRAME HOG-BASED D...AM Publications
Detecting pedestrians in low resolution videos is a challenging task, due to the small size of pedestrians in the images and the limited information. In practical outdoor surveillance scenarios the pedestrian size is usually small. Existing state-of-the-art pedestrian detection methods that use histogram of oriented gradient (HOG) features have poor performance in this problem domain. To compensate for the lack of information in a single frame, we propose a novel detection method that recognizes pedestrians in a short sequence of frames. Namely, we take the single-frame HOG-based detector and extend it to multiple frames. Our detector is applied to regions containing potential moving objects. In the case of video taken from a moving camera on an aerial platform, video stabilization is first performed to register the frames. A classifier is then applied to features extracted from spatio-temporal volumes surrounding the potential moving objects. On challenging stationary and aerial video datasets, our detection accuracy outperforms several state-of-the-art algorithms.
The aim of this paper is to help the blind people to identify and catch the public transport vehicles with the help of Light Fidelity technology. It is a Navigation aid. When the bus arrives at the bus stand, transmitter in the bus transmits the light signals and receiver in the stick, receives the light signals and a sound signal is generated through the speaker present in the stick. The sound message contains the bus number and the destination of the bus. In addition to this, if the person is absconded or lost, details of the location will be sent to his/her family members by pressing a button. This is made possible with the help of Global System for Mobile (GSM). Finally, presence of water can be detected along the blind person’s path, with the help of water sensors.
EFFECT OF SILICON - RUBBER (SR) SHEETS AS AN ALTERNATIVE FILTER ON HIGH AND L...AM Publications
A digital radiography delivers a radiation dose to patients; therefore it poses potential risk to the patients. One effort to reduce dose is carried out using a radiation filter, e.g. Silicone Rubber (SR) sheet. The purpose of this research was to determine the impact of the SR sheet on the high contrast objects (HCO) and the low contrast objects (LCO). The dose reduction was determined from attenuation x-rays before and after using the SR sheet. Assessment of HCO and LCO was observed from CDR TOR phantom at tube voltage of 48 kVp and tube current of 8 mAs. The physical parameter to assess image quality was the Signal to Noise Ratio (SNR) value in LCO. The maximum x-ray attenuation using the SR sheet is 48.82%. The visibility of the HCO remains the same, namely 16 objects; however the LCO slighly decreases from 14 objects to 13 objects after using the SR sheet. The SNR value decreases with an average value of 15.17%.Therefore, the SR sheet as a alternative filter has no effect on the HCO and has realtively little effect on the LCO. Thus, the SR sheet potentially is used for radiation protection in patients, especially on examinations that do not require low contrast resolution.

REPRESENTATION OF THE BLOCK DATA ENCRYPTION ALGORITHM IN AN ANALYTICAL FORM F...AM Publications
The article presents the study of cryptographic transformations of the Kuznyechik algorithm in relation to differential analysis and the translation of their representations into a more convenient form for cryptanalysis. A simplification of the type of transformations of the algorithm to algebraic the form, in which cryptanalysis software will be more effective. Since the description of the algorithm in the analytical form allows for 16 cycles of execution of the shift register with linear feedback, each of which will be carried out 16 operations of multiplication and 15 operations of addition, reduced to 16 multiplying and 15 the operations of addition. The result is an algebraic form of a linear transformation (from a shift register with linear feedback to the multiplication of the matrix in a finite field). In the future, the algebraic type of transformation can be used to effectively carry out differential cryptanalysis.
Optical character recognition (OCR) is process of classification of optical patterns contained in a digital image. The process of OCR Recognition involves several steps including pre-processing, segmentation, feature extraction, classification. Pre-processing is for done the basic operation on input image like noise reduction which remove the noisy signal from image. Segmentation stage for segment the given image into line by line and segment each character from segmented line. Future extraction calculates the characteristics of character. A Radial Basis Function Neural Network (RBFNN) is used to classification contains the database and does the comparison.
Surveillance refers to the task of observing a scene, often for lengthy periods in search of particular objects or particular behaviour. This task has many applications, foremost among them is security (monitoring for undesirable behaviour such as theft or vandalism), but increasing numbers of others in areas such as agriculture also exist. Historically, closed circuit TV (CCTV) surveillance has been mundane and labour Intensive, involving personnel scanning multiple screens, but the advent of reasonably priced fast hardware means that automatic surveillance is becoming a realistic task to attempt in real time. Several attempts at this are underway.
SIMULATION OF ATMOSPHERIC POLLUTANTS DISPERSION IN AN URBAN ENVIRONMENTAM Publications
Interest in air pollution investigation of urban environment due to existence of industrial and commercial activities along with vehicular emission and existence of buildings and streets which setup natural barrier for pollutant dispersion in the urban environment has increased. The air pollution modelling is a multidisciplinary subject when the entire cities are taken under consideration where urban planning and geometries are complex which needs a large software packages to be developed like Operational Street Pollution Model (OSPM), California Line Source model (CALINE series) etc. On overviewing various works it can be summarized that the air pollutant dispersion in urban street canyons and all linked phenomenon such as wind flow, pollutant concentrations, temperature distribution etc. generally depend on wind speed and direction, building heights and density, road width, source and intensity of air pollution, meteorological variables like temperature, humidity etc. A unique and surprising case is observed every time on numerous combinations of these factors. The main aim of this study is to simulate the atmospheric pollutant dispersion for given pollutant like carbon monoxide, sulphur dioxide and nitrogen dioxide and given atmospheric conditions like wind speed and direction. Computational Fluid Dynamics (CFD) simulation for analysing the atmospheric pollutant dispersion is done after natural airflow analysis. Volume rendering is done for variables such as phase 2 volume fraction and velocity with resolution as 250 pixels per inch and transparency as 20%. It can be observed that all the three pollutant namely nitrogen dioxide, sulphur dioxide and carbon monoxide the phase 2 volume fraction changes from 0 to 1. The wind velocity changes from 3.395×10-13 m/s to 1.692×102 m/s. The dispersion of pollutants follow the sequence Sulphur dioxide>Carbon monoxide>Nitrogen dioxide.

ANALYSIS ON LOAD BALANCING ALGORITHMS IMPLEMENTATION ON CLOUD COMPUTING ENVIR...AM Publications
Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
