DEPLOYING HEALTH MONITORING ECU TOWARDS ENHANCING THE PERFORMANCE OF IN-VEHIC...cscpconf
Electronic Control Units (ECUs) are the fundamental electronic building blocks of any
automotive system. They are multi-purpose, multi-chip and multicore computer systems where
more functionality is delivered in software rather than hardware. ECUs are valuable assets for
the vehicles as critical time bounded messages are communicated through. Looking into the
safety criticality, already developed mission critical systems such as ABS, ESP etc, rely fully on
electronic components leading to increasing requirements of more reliable and dependable electronic systems in vehicles. Hence it is inevitable to maintain and monitor the health of an ECU which will enable the ECUs to be followed, assessed and improved throughout their lifecycle starting from their inception into the vehicle. In this paper, we propose a Health monitoring ECU that enables the early trouble shooting and servicing of the vehicle prior to any catastrophic failure.

The Munsell color system provides a standardized way to describe colors based on three attributes: hue, value, and chroma. Albert Munsell developed the system in the early 1900s to bring order and precision to communicating about color. The Munsell system arranges all colors in a three-dimensional color space and allows any color to be accurately specified using a numerical notation of its hue, value, and chroma. The system finds wide application in fields like art, design, agriculture, science, and quality control.

Natural and mordant dyes have been used throughout history to color textiles. Natural dyes are extracted from plants, insects, and minerals and produce a limited range of dull colors with poor fastness. Mordants, such as alum, iron, tin, and copper, are used to improve color fastness when applied before or during dyeing. Modern extraction techniques, like supercritical CO2 and subcritical water, more efficiently extract dyes compared to traditional methods. The dyeing process involves pre-treating, mordanting, and dyeing fabrics to bond the natural dyes to fibers using mordant-dye chemical reactions.

fabric structure and design solution by mk39@MelkamuKenito
The document appears to be a design assignment solution submitted by Melkamu Kannito. It includes solutions to 3 questions:
1) Constructing a 40/40 diaper design with a drafting and lifting plan using a 5/5 twill weave.
2) Developing a 22/22 diamond design with a drafting and lifting plan using a 6/6 twill weave.
3) Constructing a Brighton honeycomb design with a drafting and lifting plan using a warp motif repeat size of 32.
This document discusses weaving solutions and answers questions about various weaving topics. It addresses questions about shedding mechanisms in multiphase looms, quality control systems, common weaving faults and their remedies, and parts of terry weaving machines. For each topic, it provides explanations and details in response to the specific questions asked.
Multiphase looms overcome limitations of single phase looms by forming multiple sheds across the fabric width simultaneously, allowing multiple weft yarns to be inserted in parallel. They are classified as parallel shed or wave shed looms depending on whether they form sheds in the warp or weft direction. Parallel shed looms form sheds parallel to each other in the warp direction, while wave shed looms form a shed wave in the weft direction using circular or flat machine designs. Multiphase looms allow higher production rates than single phase looms of up to 5000 meters per minute.
This document provides information on extra warp and weft figured fabrics. It discusses two methods of producing these fabrics: 1) using extra warp threads and 2) using extra weft threads. For extra warp fabrics, a separate warp beam is needed along with a dobby mechanism. For extra weft, a drop box mechanism is required. Both methods allow figuring in single or multiple colors. The document provides examples of motif designs and how the ground and extra threads interlace to produce the final figured fabric pattern.
This document discusses cotton fiber length, including factors that affect it, methods to measure it, and its influence on yarn and fabric properties. It describes how cotton length is determined by genetics and affected by environmental conditions. Methods to measure length include direct measurement of single fibers or preparing fiber bundles. Longer fibers contribute to stronger yarns and fabrics with better uniformity, less hairiness, and improved handle and luster. Shorter fibers increase processing waste and yield weaker, less even yarns.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

6. Introduction
In this material we are going to see what role
electronics has in knitting process .
Before that let’s get introduced to electronics
including computers, computer elements and circuits.
What are electronics and electronic system?
Electronics is the science that deals about electrical
devices and circuits ,including electronic knitting
machines, that operates by controlling the flow of
electrons or other electrically charged particles.
Electronic system: is the group of components
connected together to perform certain task or
function.

7. Introduction
The basic elements of electronics are
Resistors
Capacitors
Inductors
Diodes
Transistors and others
Note: these and another elements of electronics are
properly connected to each other to create a complete
path in which an electrical currents pass called circuit.

we do have different circuit that can perform
a task they are designed for.
Flip flop
Silicon circuit board
Logic gates
Optoelectronic devices and more

9. computer and microprocessor
Some elements of computer
The internal working of every computer can be broken
down into three parts:
- CPU (central processing unit),
-memory, and
- input/output devices.
In every computer there are three types of buses:
address bus (bidirectional)
data bus(unidirectional), and
control bus

11. microprocessor
Microprocessor:
Is a computer processor that integrates CPU operation in
single circuit chip. It manages information and controls what
computer does.
microprocessors vary in their memory ,processing speed
and another features.
Integrated circuit:
tiny complex connection of electronic components designed
on very small sized material. This smaller sized circuit can
perform a huge task with no need of being equal in size with
the operation. Moreover the chip is versatile which mean
that performs different tasks with no need for one-to-one
relation with the task it perform.

12. motion and its control in knitting machines
Originally there was mechanical programming and
control to knitting machines . For such system had
different drawbacks (will be seen next slides) the
system that could solve the problem as well as
provides new technologies has been designed . The
electronic system gave better control of the motion
when it’s compared with system controls before it.
Therefore let’s see what disadvantage the mechanical
control have and what better and new things do an
electrical system provided.

13. Disadvantage of mechanical
control
the limitations of mechanical movements are
- expensive to manufacture
- slow and cumbersome in operation,
- difficult to adjust or alter
- subject to friction and wear.
5/11/2019

14. mechanical programming
• Mechanical pattern and programming data for
controlling knitting machines is stored in the form of
- punched cards
- chains
- rack-wheels(wheels one above another).
-peg drums
- element butt arrangements
5/11/2019

15. Continued…
these data storage system are
-expensive in material,
-bulky in space on the machine or in storage
- time-consuming to handle and alter
- slow in operation
-provide restricted facilities.

16. Transition
In short ,Electronic controls replace mechanical controls due to
the fact that
the mechanically-controlled power flat machine is time-
consuming and costly during machine changes and its
more limited facilities provide less scope for adjustment.
In contrast, the electronically-controlled power flat
machine offers quick response to size, style and pattern
changes with versatile and infinitely variable adjustment of
its electronically-controlled functions under the guidance
of the main computer software programme and the
back-up support of its memory.
It is therefore more able to efficiently meet the
exacting requirements for knitting shaped garments.

convenient power-supply.
compatibility with existing mechanical components.
micro-miniaturization of circuitry (designed in very small size).
economical data storage.
In addition, electronic systems do not require

Electronic selection or machine control
is compatible with higher running speeds
eliminates complex mechanical arrangements then
reducing supervisory requirements.
It provides greater versatility as regards design
parameters
simplifies the modification of repeat sequences and
size, style and pattern-changing operations
In some cases, enables changes to occur whilst the
machine is knitting.

20. The compatibilityof electronicsignals and
knitting data
Electronic devices process information as binary digital logic
signals that exist in two states, ON or OFF.
This can be directly translated as
- 1 or 0,
- YES or NO,
- TRUE or FALSE,
- magnetic ATTRACTION or REPULSION.
This information can just as conveniently be translated into
knitting states such as
KNIT or TUCK,
TUCK or MISS.
The binary digits can be arranged in the form of a programme
where they can be encoded and converted into symbols to
compose, for example, a knitting design or a machine
programme.
5/11/2019
21. Continued…
For instance:
If the following logical circuit is assumed to work inside the
knitting machine. An output that will be found at E depends
on what is given as an inputs from A-D. the state of an
inputs can never be out of either on(1) or off(0).
Then for the following particular logical circuit the binary
inputs can give either KNITT/ TUCK or TUCK/MISS for

22. Microprocessors and computers
The most important use of electronics is in
microprocessor and computer systems.
A computer:
can receive, store, retrieve, and communicate
enormous quantities of information at phenomenal
speeds.
It can manipulate, rearrange, select, and transform
this information.
It performs arithmetical or logical processes ( with
ALU)accurately at high speed after receiving the
instructions (programme) and values (data) without
the need for further intervention by the operator
5/11/2019

23. Continued… (…computer)
Flexibility in processing of data occurs because the
system can be programmed to produce YES or NO
decisions, based on the result of comparing and
testing monitored data, that then determine the choice
of two alternative courses of action in the program of
the system.
These alternative courses within the main program
sequence may include counted loop sequences,
branching or jumping out of the main sequence, and
selection of stored sub-routines.
5/11/2019

24. Continued… (…computer)
It is these facilities that give electronically-controlled
knitting pattern preparation and needle selection
their extensive capabilities as compared with
previously available methods.
Inputs include switches, sensors on knitting
machines, keyboards, light pens, tapes and discs; and
outputs include actuators on knitting machines, lights,
digital and graphical displays, tapes, and printers.
Outside the system, the digital impulses may be
changed from parallel to serial, or even analogue,
form, or may be converted into light, sound, radio or
carrier waves, or mechanical movements.

25. Continued… (…computer)
Although it is possible to directly program a system by
using an input devices, the processor (and probably
the knitting machine) will be held waiting during this
time-consuming operation.
It is therefore preferable to record the program and
data in an auxiliary memory store such as a tape(disc).
Its contents(content of the memory or the pattern
stored in it) can be rapidly inputted electronically into
internal memory, as required.
whilst using a direct input keyboard or switches for
minor amendments or alterations during the running
of the programme

Some systems are programmed to interact with the
operative who is thus able, within specified and
guided limits, to change values of data, with the effects
of the amendments being visually indicated by the

27. The computerized knitting machine
Although knitting is still a mechanical action between
the yarn and the knitting elements, the design of
tomorrow’s machines will be increasingly influenced
by the facilities offered by electronics as shown below.

Motion bulkiness
• Thus, whereas on mechanically controlled knitting
machines nearly all the mechanical movements are linked
to the revolution of the machine or traverse of the cam
carriage, electronic controls can be dispersed and
separately operated.
Process stages
• In addition, their operation can be smoothly introduced in
a series of gradual steps and not in a restricted number of
large steps, as is the case with mechanical drive systems.
Note: In short mechanical systems can have few huge and
complicated stages per operation but electronic systems
separates the operation into sub smaller operations that
makes it easier.

The electronically-controlled knitting machine can be part
of a network of management communication links.
Process control
A single control unit can control a complete bank of
machines if necessary .Unlike the mechanically-controlled
machine which stands alone and has no means of receiving
and transmitting electronically generated data .

Design description with Cartesian co-ordinate
The position is defined and located by two numbers
in the Cartesian co-ordinate system.
• On the horizontal (X) axis, the numbering increases
positively from zero towards the right,
• whilst on the vertical(Y) axis, the numbering increases
positively upwards from zero at any point on the
design.
• Generally, an input device is employed that can be
moved by hand in the direction of either axis, with its
location and movement over the screen being
indicated by a special character symbol termed a
cursor.

It provides a much quicker response to customer
requests(quick knit sample development) than is
possible with traditional knit sampling techniques
whilst postponing the expensive knitting operation

39. The Stoll CADpatternpreparationsystem
The Stoll SIRIX is a complete design, patterning and
programming system originally specially developed
from Apple II PC software.
It is used in every application in V-bed flat knitting.
It uses icons and windows to graphically support the
generation and development of knitting programmes
for Stoll CMS electronic flat machines.
It simplifies pattern drafting and speeds-up the
processes required in the production of knitted fabric
and garments.
Fabric depiction and programme drafting is carried
out on-screen, without the need to interrupt
production on the machine.

In Stoll CAD system
Patterns can be designed using jacquard colors and the Sintral
programming language, or directly by defining stitches and
modules.
These can then be transformed automatically into a knitting
programme simply by pressing a button.
Sintral is the text editor, which facilitates the creation of knitting
programmes using plain language instructions.
Designs or programmes are analyzed, processed and tested, then
automatically translated into Sintral, then presented to the
monitor or loaded into the machine.
The design programme is a ‘Paint’ programme that provides a
palette of colors, shades, brush shapes and sizes, and design
tools.

Using the yarn programme, yarn types, shades, and
textures can be generated and stored to closely simulate
knitted panels, in advance of the knitting process.
Sophisticated color printers can produce realistic images of
the garment which, it is hoped, will reduce the time-
consuming process of swatching and sample development
on the knitting machine.
Once the design is completed, a model can be called-up
onto the screen whose three-dimensional appearance
simulates the wearing of a garment made from the design.

The Shima Total Design System is a totally-integrated
knit production system.
It allows all stages to be integrated into a smooth work-
flow.
Shima integrates planning, design, evaluation,
production, and sales promotion .
1. The designer creates concept drawings. This can be
done by using computer-graphic paint software and a
pressure-sensitive airbrush .the concept drawing is
realized by knit technicians with capability of the
machine. Then, How does the designer communicate
