This study is an approach to investigate the viable impacts of Grub screw manufacturing. Due to
increase in demand of grub screw in industry it leads the manufacturer to upgrade the exiting process of
manufacturing the grub screw. A method and apparatus for manufacturing a screw capable of mass-producing a
multiple screw bolt such as a so-called grub screw, grinding and slotting for use therein. By making the existing
machine semi automatic to increase the production rate as well as to reduce the man power required for the
production process. Grub screw manufacturing process consists of COLD FORGING, SLOTTING, GRINDING
and ROLL THREADING. Slotting machine cuts the slot on the top of screw head. The feeding mechanism demands
human effort causing slow production rate and time consuming process. To eliminate this we come up with semiautomatic bowl feeder. As similar problem is faced in the grinding process we decided to combine the slotting
and grinding machine into one. This project is focused on increasing the production rate with minimal man power
by consuming less amount of time compared with the existing process. For this purpose, an optimized design of
existing machine is made consisting of cost effective & quality materials.

Need of Lapping Machine for Valve Component: A Case StudyIJMER
ABSTRACT: Lapping process is characterized by its low speed, low pressure, and low material removal rate. This process
is used in achieving finer surfaces and closer fits, correction of minor imperfections, and maintaining close tolerances.
During the process of lapping, the mechanisms of surface formation and removal rate are decisively influenced by
the movement type of the individual grains within the lapping abrasive. A gate valve is used to start and stop the flow of
fluid. So the wedge and seat ring of a valve are in continuous pressure of fluid flow and due to opening and closing of valve
these component get wear and they need lapping during reconditioning. This paper will share the need, requirement and
application of lapping during the reconditioning of valve.
This paper will explore the current working condition of lapping machine in valve industry. It will elaborate the
effect of abrasive particals, working speed, surface roughness and other related parameters. What are the difficulties they
are facing during the valve reconditioning related to lapping, will be disscussed.Current set up and the changes required in
this model are suggested with the proposed model.
Key words: Lapping process, wedge, seat ring, abrasive particles.

“Design and Fabrication of Pedal Operated Groundnut Decorticator Machine”IJMERJOURNAL
ABSTRACT : In India, groundnut is grown on a small scale by farmer. The major problem in groundnut production in our country like India is the lack of groundnut processing machines available to farmers. The main aim of this project is to design and fabricates a low cost groundnut decorticator machine which will help small farmer to decorticate finished groundnut instead of unfinisheds groundnut. This groundnut decorticator machine works on quick return mechanism main working of this project. In which we made a pendulum with rubber pad is fitted on a shaft. The rubber pad is used for free crushing of groundnut and to reduce the damage of groundnut. If we go on continuous work we got greater output in very short time. The study reveal that pedal operated groundnut decorticator gave an output of 49 kg/hour which was more than hand operated decorticator. This machine requires less effort to decorticate groundnut with higher output. The performance of machine was evaluated in terms of throughput capacity, decorticating efficiency and damage percentage. By keeping this point in our mind we think that we should make such machine whose production capacity is more and machine get pedal operated. The small scale farmers and can start their business by investing less capital.

Design and Fabrication Multi Spindle Drilling Machineijtsrd
Generally, the growth of Indian manufacturing sector is largely depends on productivity and quality. Productivity depends upon various factors, one of the major factors is efficiency with which the operation activities are carried out in the industry. Productivity can be highly improved by reducing the machining time and combining the operations etc. As the name indicates multi spindle drilling machines have two spindles driven by a single power head, and these two spindles holding the drill bits are fed into the work piece simultaneously. We can drill two holes at a time with provision of varying centre distance between two drilling spindle. It has advantage of portability. In the conventional manner only one drill can be drilled at a time, but with increase in productivity demands a special purpose machine is needed which will increase productivity by performing multiple operations in one cycle. The Multi spindle drilling machine is an ideal solution to the above problem which is used to perform multi drilling operations at a time.

Structural and Morphological Studies of Nano Composite Polymer Gel Electroly...vivatechijri
n today’s society, we stand before a change in energy scarcity. As our civilization grows, many
countries in thedeveloping world seek to have the standard of living that has been exclusive to a few nations, so
their arises a need in thedevelopment of technology that is compatible enough with the resources provided by
nature in order to have sustainabledevelopment to all class of the society. In order to overcomethe prevailing
challenges of huge energy crises in near future, there is an urgent need for the development of electrical
vehiclesor hybrid electrical vehicles with low CO2 emissions using renewable energy sources. In view of the
above, electrochemicalcapacitors can fulfil the requirements to some extent.Preparation of nano composite
polymer gel electrolyte is the best optional product to overcome these problems. When fillers are added or
dispersed to the polymer gel electrolyte, amorphous or porous nature of electrolyte increases which enhances
the liquid absorbing quality of polymer and helps in removing the drawbacks of polymer gel electrolytes such as
leakage, poor mechanical and thermal stability etc. In this work dispersion of SiO2 nano filler is done in the
[PVdF (HFP)-PC-Mg (ClO4)2] for the synthesis of nano composite PGE [PVdF (HFP)-PC-MgClO4- SiO2].
Optimization and characterization was carried out by using various techniques.

METHODS FOR DETECTION OF COMMON ADULTERANTS IN FOODvivatechijri
Food is essential forliving. Food adulteration deceives consumers and can endanger their health. The
purpose of this document is to list common food adulterant methods commonly found in India. An adulterant is
a substance found in other substances such as food, cosmetics, pharmaceuticals, fuels, or other chemicals that
compromise the safety or effectiveness of that substance. The addition of adulterants is called adulteration. The
most common reason for adulteration is the use of undeclared materials by manufacturers that are cheaper than
the correct and declared ones. The adulterants can be harmful or reduce the effectiveness of the product, or
they can be harmless.

An Alternative to Hard Drives in the Coming Future:DNA-BASED DATA STORAGEvivatechijri
Demand for data storage is growing exponentially, but the capacity of existing storage media is not keeping up, there emerges a requirement for a storage medium with high capacity, high storage density, and possibility to face up to extreme environmental conditions. According to a research in 2018, every minute Google conducted 3.88 million searches, other people posted 49,000 photos on Instagram, sent 159,362,760 e-mails, tweeted 473,000 times and watched 4.33 million videos on YouTube. In 2020 it estimated a creation of 1.7 megabytes of knowledge per second per person globally, which translates to about 418 zettabytes during a single year. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for quite a century. Running data centres takes vast amounts of energy. In short, we are close to have a substantial data-storage problem which will only become more severe over time. Deoxyribonucleic acid (DNA) are often potentially used for these purposes because it isn't much different from the traditional method utilized in a computer. DNA’s information density is notable, 215 petabytes or 215 million gigabytes of data can be stored in just one gram of DNA. First we can encode all data at a molecular level and then store it in a medium that will last for a while and not become out-dated just like floppy disks. Due to the improved techniques for reading and writing DNA, a rapid increase is observed in the amount of possible data storage in DNA.
The usage of chatbots has increased tremendously since past few years. A conversational interface is an interface that the user can interact with by means of a conversation. The conversation can occur by speech but also by text input. When a chatty interface uses text, it is also described as a chatbot or a conversational medium. During this study, the user experience factors of these so called chatbots were investigated. The prime objective is “to spot the state of the art in chatbot usability and applied human-computer interaction methodologies, to research the way to assess chatbots usability". Two sorts of chatbots are formulated, one with and one without personalisation factors. the planning of this research may be a two-by-two factorial design. The independent variables are the two chatbots (unpersonalised versus personalised) and thus the speci?c task or goal the user are ready to do with the chatbot within the ?nancial ?eld (a simple versus a posh task). The results are that there was no noteworthy interaction effect between personalisation and task on the user experience of chatbots. A signi?cant di?erence was found between the two tasks with regard to the user experience of chatbots, however this variation wasn't because of personalisation.

Cross Platform Development Using Fluttervivatechijri
Today the development of cross-platform mobile application has under the state of compromise. The developers are not willing to choose an alternative of either building the similar app many times for many operating systems or to accept a lowest common denominator and optimal solution that will going to trade the native speed, accuracy for portability. The Flutter is an open-source SDK for creating high-performance, high fidelity mobile apps for the development of iOS and Android. Few significant features of flutter are - Just-in-time compilation (JIT), Ahead- of-time compilation (AOT compilation) into a native (system-dependent) machine code so that the resulting binary file can execute natively. The Flutter’s hot reload functionality helps us to understand quickly and easily experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM). With the help of Flutter, we believe that we would be having a solution that gives us the best of both worlds: hardware accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems.

Recommender System (RS) has emerged as a significant research interest that aims to assist users to seek out items online by providing suggestions that closely match their interests. Recommender system, an information filtering technology employed in many items is presented in internet sites as per the interest of users, and is implemented in applications like movies, music, venue, books, research articles, tourism and social media normally. Recommender systems research is usually supported comparisons of predictive accuracy: the higher the evaluation scores, the higher the recommender. One amongst the leading approaches was the utilization of advice systems to proactively recommend scholarly papers to individual researchers. In today's world, time has more value and therefore the researchers haven't any much time to spend on trying to find the proper articles in line with their research domain. Recommender Systems are designed to suggest users the things that best fit the user needs and preferences. Recommender systems typically produce an inventory of recommendations in one among two ways -through collaborative or content-based filtering. Additionally, both the general public and also the non-public used descriptive metadata are used. The scope of the advice is therefore limited to variety of documents which are either publicly available or which are granted copyright permits. Recommendation systems (RS) support users and developers of varied computer and software systems to beat information overload, perform information discovery tasks and approximate computation, among others.

Social media platform and Our right to privacyvivatechijri
The advancement of Information Technology has hastened the ability to disseminate information across the globe. In particular, the recent trends in ‘Social Networking’ have led to a spark in personally sensitive information being published on the World Wide Web. While such socially active websites are creative tools for expressing one’s personality it also entails serious privacy concerns. Thus, Social Networking websites could be termed a double edged sword. It is important for the law to keep abreast of these developments in technology. The purpose of this paper is to demonstrate the limits of extending existing laws to battle privacy intrusions in the Internet especially in the context of social networking. It is suggested that privacy specific legislation is the most appropriate means of protecting online privacy. In doing so it is important to maintain a balance between the competing right of expression, the failure of which may hinder the reaping of benefits offered by Internet technology

A Study of Tokenization of Real Estate Using Blockchain Technologyvivatechijri
Real estate is by far one of the most trusted investments that people have preferred, being a lucrative investment it provides a steady source of income in the form of lease and rents. Although there are numerous advantages, one of the key downsides of real estate investments is lack of liquidity. Thus, even though global real estate investments amount to about twice the size of investments in stock markets, the number of investors in the real estate market is significantly lower. Block chain technology has real potential in addressing the issues of liquidity and transparency, opening the market to even retail investors. Owing to the functionality and flexibility of creating Security Tokens, which are backed by real-world assets, real estate can be made liquid with the help of Special Purpose Vehicles. Tokens of ERC 777 standard, which represent fractional ownership of the real estate can be purchased by an investor and these tokens can also be listed on secondary exchanges. The robustness of Smart Contracts can enable the efficient transfer of tokens and seamless distribution of earnings amongst the investors. This work describes Ethereum blockchainbased solutions to make the existing Real Estate investment system much more efficient.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
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!

Abstract : This study is an approach to investigate the viable impacts of Grub screw manufacturing. Due to
increase in demand of grub screw in industry it leads the manufacturer to upgrade the exiting process of
manufacturing the grub screw. A method and apparatus for manufacturing a screw capable of mass-producing a
multiple screw bolt such as a so-called grub screw, grinding and slotting for use therein. By making the existing
machine semi automatic to increase the production rate as well as to reduce the man power required for the
production process. Grub screw manufacturing process consists of COLD FORGING, SLOTTING, GRINDING
and ROLL THREADING. Slotting machine cuts the slot on the top of screw head. The feeding mechanism demands
human effort causing slow production rate and time consuming process. To eliminate this we come up with semi-
automatic bowl feeder. As similar problem is faced in the grinding process we decided to combine the slotting
and grinding machine into one. This project is focused on increasing the production rate with minimal man power
by consuming less amount of time compared with the existing process. For this purpose, an optimized design of
existing machine is made consisting of cost effective & quality materials.
Keywords - Grub Screw, Semi Automatic, Reduce Human Efforts, Bowl Feeder, Cost Effective, Better
Efficiency, Increase Productivity & Consuming Less Time.
I. INTRODUCTION
Grub Screws are a sort of fastener, in some ways like a bolt, typically product of metal, and characterized by a
helical ridge, referred to as a male external thread. Grub Screws are accustomed fasten materials by digging in
and wedging into a material when turned, while the thread cuts grooves within the fastened material that will
help pull fastened materials together and stop pull-out.
1.1 Project Background
The concept of Grub screws came into existence since olden times, predating the metal screw by at least several
hundred years. Screw manufacturing is being chosen for this study and it is among the most established
manufacturing industry, screw can be categorized as non-permanent joint or fastener, it is used to join parts that
can be easily disassembled. Screw can join metal part with non-metal part, it can join any parts together from any
kinds of material, and Screw is non-permanent join so it is suitable for design that need disassemble for
maintenance purpose. That is why it widely used in industries, home appliance, automotive industries, and
electronic industries and building structures.

1.2 Purpose of Project
Grub Screws are known as industrial fasteners having different types & shapes of heads, lengths and diameters.
These are mostly manufactured from 15B25 Wire. The product is Cold Forged, Slotted, Grinded and Roll
Threaded. These are used for fastening of mixers, Brake caliper, and grinder machine. Grub Screw is headed and
externally threaded, possessing capabilities which permit it to insert into hole and forming its own thread, when
being tightened. The project work presented in this report is based on improvement and optimization of grub
screw in screw manufacturing company. Making a machine was not just our main objective, but making the
current machine optimize and making mechanism more efficient to increase the production was the main reason
for us to select this project.
The manufacturing of Grub screw is done at small scale industry. The current machine in the company is not
much efficient to produce the current production requirement of the Industry. So our main objective was to
accommodate all of this in one project.
So our project deals with optimizing some parts of machine and modifying it for better performance and reducing
its cost, with minimum human efforts and also within the given deadline.
II. PROBLEM STATEMENT
Due to current method of manufacturing Grub Screw, it does not meet the requirement of the market which
affects the rate of production and also there are lot many manual operations for each process to be performed.
Due to which the time required for each operation increases and doesn’t make the required quantity. The main
processes during the manufacturing are cold forging, slotting, grinding and roll threading. During the operation
of Slotting & Grinding the work piece are feed manually. Due to which the time required for each process
increases and leads to slow down the production rate and the manufacturer lacks to produce required quantity
within the given deadline.
2.1 Objectives
Objectives to be minimized are given below
2.1.1 Manually Feeding
As the major process includes the slotting and grinding of the grub screw. Because of there is no head on the
grub screw, feeding of the screw is to be done manually. While feeding in the conventional machine the work
piece slides down and falls into the machine as there is no head. Due to continuous human feeding the work
piece gets stuck into the machine and it leads to stop the machine and reset the machine by adjusting the grub
screw.
2.1.2 Grinding Of the Grub Screw
The current machine in the company is the common vertical bench grinder. So the feeding of the grub screw in
done with the help of a plate which consist of 1360 holes drilled into the metal plate. To fill the plate with the
grub screw which is to be grind from the bottom side (top side is being slotted first) is filled with the help of two
persons which takes time around 10 minutes after that the plate is being mounted on the bench of the vertical
grinder with the help of magnetic bench and the operation is performed 2-3 times by adjusting the feed rate of
the machine after that unloading is done. This takes time of 4-5 minutes .So the total time required for the
grinding process is all about 15-16 minutes, which leads to slow down the process, time consuming & affecting
the production rate.
2.1.3 Roll Threading Operation
In The current process the work piece needs to be feed manually into the machine through a screw which has a
hole through out the length which is provided over the threading die. As there is manual feeding by hand there is
chance of excessive feeding at a time into the machine die which leads to stops the rolling process. Then again
we have to restart the machine by removing the stuck screw from the die so that it can work properly. Again the
whole process leads to slow down the process and affects the production rate by consuming much time.

2.1.4 Hectic Process & Human Safety
As the whole process needs labor support for feeding operation the process is much hectic as well as there are
chances of getting hands into the machine while operating, during the grinding process there is chance of
breaking of the grinding wheel when it comes to end part which risks the life of the human.
III. METHODOLOGY
The solution for all this process is that we have proposed an idea for making this process semi-automatic which
helps to feed the work piece into the machine. We have majorly combined the two process that are 1) Slotting
Operation & 2) Grinding Operation. Because this two are the major time consuming operation in the whole
production process. So that it will help us to achieve the required production rate in the given amount of time.
3.1 Working Mechanism
1. Firstly the conventional industrial cold forging machine gives us the work piece in the form of small bullet
shape structured, of the dimension 16.50 mm-length & 6mm diameter.
2. Now further we have to put the grub screw obtained from the cold forging operation into the rotary table.
Then due to rotation of the plate attached inside which has slots made over the circumference of the plate which
helps the grub screw to hold into position while rotating and to push the screw into the bent pipe so that it could
transfer to further process.
3. When it comes from bent pipe it is transferred to the turn table attached below which again hold the grub
screw into position while rotating. There is a cutter attached at upper position of the turn table .The height of the
cutter can be adjusted with the help of the ball screw which is attached with the cutter.
4. As soon as the Grub Screw comes below the cutter, screw moves with a constant speed and slots are created
after a moment the turn table rotates further and the grub screw is moved further by the guide way provided in
the tangent to the turn table which transfers the grub screw into a conveyor chain system which helps the Grub
Screw to travel from cutter section to the grinding operation.
5. At the bottom part of the conveyor chain the grinders are attached. Due to which the grinding operation is
done simultaneously. Supporting plate is provided to hold the screw in the position, So that the grinding
operation can be done properly without slipping of the Grub Screw.
6. There are 3-Grinders attached at the bottom of the conveyor with the help of the ball screw, so that the feed
of the grinder wheel can be adjusted with the help of ball screw mechanism.
7. After all these operations are complete the grub screw falls into the collector box provided below.
