Loom is machine or device which is used to produce woven fabric. It is the central point of whole process of cloth production. In other word, a loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing hand looms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom. The main task of looms is to clutch the twist threads under pressure to enable the progress of interweaving of the woof strands. The loom's system and exact form can differ to some extent; however it still performs the basic application.

Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns ("wales") of knitting, rather than a single row ("course"). For comparison, knitting across the width of the fabric is called weft knitting
A line along which two or more fabric parts are joined by sewing is called seam.
Again A stitch line where fabrics are joined together by various fabric arrangements.
So we can say that the line of joining fabric is called seam.
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.

Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas.

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
4. Shed and Shedding:
Shed: Devidation of warp threads into two parts for
insertion of weft threads is called shed.
Shedding: the mechanism of shed is called
shedding.
It is the first primary motion of weaving.
6. TYPES OF SHED:
There are four types of shedding.
Center close shed
After inserting a pick, both the lines meet at the center
between the highest and lowest line of a divided warp.
Bottom close shed
This kind of shed is known as a stationary bottom
with a rising and falling top.
Semi open shed
A stationary bottom line is refined, but threads from
the top line either pass to the bottom at one movement
or carried out to the top. The remaining threads move
down.
Open shed
In this types of shed, the warp threads from two
stationary lines, one at the top and another at the
bottom. After inserting a pick change are made by
carrying threads from one fixed line to other.

7. A→ Bottom line of warp
B→ Rising and falling line
C→ An arrow showing
the space passed
through
1.Bottom close shed:
This type of shedding is produced by
giving motion only to threads that are to
form the upper line. Under this condition,
the warp is level on the bottom line.
Hence in order to form a top shed, it is
necessary to move some threads
through a space equal to twice the depth
of a shed, once up and down, before a
fresh selection is made. A shed of this
kind is known as stationary bottom with
a rising and falling top.
8. Advantages:
Alternate tightening and slackening the warp threads produce a
covered cloth
Produce fire fabric (silk)
Used in hand loom
Disadvantages:
More stress or tension on the top warp line and less tension on the bottom
warp line.
More chance of breakage on top warp line
Unequal warp tension produces poor quality fabric
Loom speed/ waving speed is slower
Not possible to produce compact fabric
More power consumption
More time required
9. 2. Center close shed:
This type of shed is produced by imparting an upward movement
to those threads which are to form the top line and the downward
movement to the threads which are to form the bottom line. Then
after inserting a pick, both the lines meet at the center between the
highest and lowest lines of a divided warp.
A→ Closed warp line
B, C→ Upper and lower lines of a divided warp respectively
D→ Arrow showing the half distance of a shed in an upward direction
E→ Arrow showing the half distance of a shed in a downward direction
10. Advantages:
Equal tension on the top and bottom warp
line
Less time required so high production
Less wear of the m/c
Less power consumption
Less tear of the threads
Disadvantages:
Beat up takes place in the closed shed
condition
There is chance of weft being moved
backward
Compact fabric can not be produced by this
shed
11. 3. Semi-open shed:
In this shed, the stationary bottom is retained but threads for the top line either passes to
bottom at one movement and again carried to the top mid way and again carried to top. In this
shed close and open shed occurred simultaneously. In it the stationary bottom line is retained,
but threads for the top line either pass to the bottom at one movement, or are arrested midway
and again carried to the top. Such a shed can be formed as expeditiously as an open shed, for
the upward movement begins and ends with the downward through movement, and the
arrested downward movement is converted into an upward movement immediately the falling
threads are in the same plane as the rising ones. They all reach the top together but the strain
upon them is not equally distributed.
A→ Stationary bottom line
B→ Top point
C→ The point where downward movement ceases in threads
D, E→ Showing the movement of through healds
F→ Arrow showing the threads which are to lift for the next pick
12. Advantages:
Equal tension on the top and bottom warp
line
All the warp yarns are not required to move
up and down in every pick
Beat up takes places in the cross-shed
condition
The loom can run at a faster speed
Possible to produce compact fabric
Less complexity or disturbance in the
shedding mechanism
Used in power, dobby & jacquard loom
For fancy fabric
Less power consumption
Less tear of threads
Disadvantages:
Unusable movement
13. 4. Open shed:
In open shed, the warp threads form two stationary
lines, the top line and the bottom line and changes are
made by carrying the threads from one fixed line to the
other without any interval.
A, B→ Stationary warp line
C, D→ Arrows which show the movement of rising
and falling warp to equal the distance between A & B
14. Advantages:
Beat up takes place in cross-shed condition
Equal tension on the top and bottom warp line
The loom can run at a fastest speed
Extensively used in tappet shedding mechanism
Basic fabric (twill, sateen, plain) can be produced.
Less power consumption
Less wear of the weaving m/c
Disadvantages:
High breakage rate
If higher no of healds are used then the warp in back healds
are more strained than the front ones
Leveling apparatus should be added to open shed to place
the headls in one plane
