The document analyzes thickness profile data from two Tata Steel plants - Tarapur and Jamshedpur - using box plots and control charts. Box plots of strip thickness data for various coil thicknesses like 1mm, 1.5mm, and 2mm show that Jamshedpur coils have tighter distributions and fewer outliers compared to Tarapur coils. Control charts also indicate that Jamshedpur coils have more symmetrical and convex thickness profiles across coil widths that are closer to specifications, making them more suitable for customers following lean manufacturing principles. The analysis concludes that Jamshedpur has superior strip thickness profiles and widths that provide competitive advantages in today's global market.
THE METHOD FOR OPTIMUM DESIGN OF RESIN INJECTION MOLDING PROCESS CONDITIONS U...meijjournal
In recent years, the demand for plastic products has increased, and along with the deepening of academics,
mass production, weight reduction, and high precision are progressing. In the fields of design development
and production technology, there are many issues related to quality assurance such as molding defects and
product strength. In particular, in the resin molding process, there is a high degree of freedom in product
shape and mold structure, and it is an important issue to create quality functions that apply analysis of
complex multidimensional information. In this study, the important factors of the resin molding process
related to the optimization of resin strength are extracted by applying the multivariate analysis method and
robust parameter design. As a result of verification of the proposed method, it is clarified that uniformization
of the resin filling density in the mold is extremely important for stabilizing the resin strength.
Design of Different Types of Corrugated Board Packages Using Finite Element T...SIMULIA
From a structural point of view, corrugated board would fit on the category of sandwich structures, which in sectors as aeronautics or construction are today commonly analysed using simulation tools that are based on the Finite Element Method. However, in spite of similarities to applications in other materials, FEM simulation of corrugated board is a high challenging modelling task due not only to the need of addressing properly the complex mechanical modelling of paper itself, but also because of phenomena that are directly related to the corrugated structure, as the relationships between local and global instability failure modes. The present paper, through a set of application examples, shows how different Abaqus modeling capabilities (SC8R elements, composite sections, connector elements, …) can be applied for solving the different difficulties that arise when modelling corrugated board. The integration of these capabilities has led to the development of virtual prototypes for the two most common corrugated board packages: B1 boxes and agricultural trays. From the experience in these box types, and taking advantage from the inherent modelling simplicity of the composite layered models together to the flexibility offered by the available modelling techniques in Abaqus, these virtual prototypes have been extended as a design tool for very different types of corrugated board packages.

Machining of duplex stainless steels: a comparative studyRasper Dellshad
This paper investigates the machining of super duplex EN 1.4410, standard duplex EN 1.4462 and austenitic EN 1.4404 stainless steels through a two-phase experimental study. In the first phase, a new methodology based on Mamdani fuzzy interference of classified chip shapes in chip breaking charts to predict the chip volume ratio is presented. Chip volume ratios, specific cutting pressures, cutting powers and resultant cutting forces are considered as performance characteristics and converted into single indices using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), Grey Relational Analysis (GRA), VIKOR method and Utility Analysis (UA). An expert system based on fuzzy rule modelling approach is then adopted to combine the computed indices into a single Universal Characteristics Index (UCI). Results showed that converting the output of different Multiple Attribute Decision Making (MADM) methods into a single UCI index is a simple and efficient technique in determining an optimal combination of the cutting parameters. Constrained simulated annealing optimization procedure is then employed to evaluate the optimal process parameters thereby satisfying conflicting requirements of each of performance factors. First ranking UCI values are analyzed and compared with the output of multi-objective optimization techniques (MOO) using Weighted Sum Method. A remarkable improve in reduction of cutting power consumption, specific cutting pressure, resultant cutting forces are reported when first rank UCI value is directly reported as optimum point instead of performing conventional optimization. In the second phase, cutting force and machine current consumption signals are adopted as indirect cutting tool wear monitoring techniques to graph the tool wear progression. Results showed that the tool life strongly affected by cutting speed and workpiece material.

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.

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.
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.

I. INTRODUCTION
Six Sigma is a quality improvement programme with a
goal to reduce the number of defects as low as 3.4 parts
per million. Six Sigma is a methodology provides
businesses with the tools to improve the capability of their
business processer. The Six Sigma approach was first
developed in the late 1980s within mass manufacturing
environment in Motorola. In Six Sigma, the purpose of
process improvement is to increase performance and
decrease performance variation. The DMAIC
methodology consists of, succinctly, in defining (D) and
measure (M) the problem, analyse (A) Plan for data
collection; analyse the data and establish and confirm the
“vital few” determinants of performance, improve (I) the
process to remove the root causes and control (C) or
monitor the process to prevent the reappearance of
defects. Box Plot is one of the statistical tools used for Six
Sigma data analysis, useful in identifying outliers and
comparing distributions.
John Tukey introduced the box plot as part of his toolkit
for exploratory data analysis (Tukey, 1970), but it did not
become widely known until formal publication (Book-
Exploratory Data Analysis, Tukey, 1977). In 20th century
Box Plot has become one of the most frequently used
statistical graphics. When comparing distributions
between batches, Tukey’s boxplot is commonly used. Box
plot is based on robust statistics, i.e. it is more tolerant (or
robust) to the presence of outliers. It gives an indication of
shape of distribution in terms of symmetry. It is an
excellent means to determine if there are similarities (or
differences) between two or more data sets by juxtaposing
their box plots.
Fig. a: Box plots illustrate the signal (the center) and noise
(the spread of data from the center) in their representation
yet according to Biehler (2004) the interpretation of
spread can result in five different views, namely: location
information, regional spreads and densities, global spread
as a deviation from the median, median upward and
downward spread, and classification information.
Figure a.
A Box Plot, the input data set is split to quartiles as in
boxplots, the median, 25th, and 75th percentiles are
marked with line segments across the box. (“Minimum”,
first quartile (Q1), median, third quartile (Q3), and
“maximum”) It can also tell you if your data is
symmetrical, how tightly your data is grouped, and if and
how your data is skewed. Box Plot graph only work well
when there is enough data to provide the statistics.
II. CASE STUDY
The purpose of this case study is to comprehend the Strip
profile of two Tata Steel plant i.e. Tarapur and
Jamshedpur plant CRCA coil. Strip profile is defined as
variation in thickness across the width of the strip. It is
usually quantified by a single value, the crown, defined as
the difference in thickness between the centre line and a
line at least 40 mm away from the edge of the strip
(European Standard EN 10 051).
As Tata Steel company manufacture the CRCA coil in
negative side of thickness, which directly benefit to
customer end. Most of customer depend lower side
thickness within tolerances for their manufacturing
product or component specially by Stamping, Auto,
Electical lamination industries.

In todays globalisation world, as competition intensifies,
providing quality products and services has become a
competitive advantage and a need to ensure survival. The
strip profile is one of the parament in sheet metal
industries which increase profit (increase in number of
parts/ components due to negative thickness with in
specification limits) without any exertion. Tata steel
mostly focuse on strip profile in negative side rolling as
per market demand. Jamshedpur coil Strip and Width
profile is much better and close to the median, by Control
Chart shows the convex curves which represent the work
roll crown and rolling methods.
