memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs
Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

9. Paper Pulp
● Paper pulp is a lignocellulosic fibrous material prepared by
separating cellulose fibers from wood fibers or recycled materials
through the pulping process.
● Paper pulp made from wood fiber is usually a combination of paper
pulp from softwood and hardwood.
● Softwood provides strength while hardwood provides softness to
tissue paper.
● Recycled paper pulp is recycled paper which has been processed to
removing unwanted elements and freed the paper fibres.
Bleach
● Bleach is chemical material used to lighten the color or whiten the
tissue paper.
● Bleach commonly used in tissue paper production is chlorine dioxide
and hydrogen peroxide.

MANUFACTURING
PROCESS
15. •Pulping
1.Trees are logged and cut into chips, which are then grounded into fine flakes,
which are then soaked and pulled-apart (retted). Paper pulp is generated from wood
fibre or recycled materials.
2.Stirred together these fine retted flakes in a mixer tank with a large quantity of
water and other chemicals generates.
3.The manufacturer adds chemicals such as sodium sulphide, limestone, and others
while the wood pulp is still in the mixing tank, to soften, strengthen and colour the
paper.
16.
17. •Pressing
1.The prepared pulp is then poured over fast moving belts made from highly porous
materials that are driven over huge drums heated by a flow of steam. The pulp is poured
uniformly and consistently across the width of the belt/drum. All the water escapes
through the pores, leaving just the fibres on the belt in the form of a delicate fabric.
2.The tissue is then transferred on to a massive heated roller called a Yankee. The heat
of the Yankee makes the fabric dry almost instantly.
3.The tissue paper is then transferred on to a core to form a large diameter roll.
4.Adjust the draw speed of the roll can let you get a thicker or thinner tissue as per your
goal.
5.The rolls are then put onto the converting machine.
18.
19. •Converting
1.The tissue is taken and its plies are split and passed through an embossing roller.
2.Embossing softens the toilet tissue and can be used to create decorative patterns.
3.The plies are removed and held together with glue. The tissue is then perforated by
doctor blades, enabling the sheets to be easily pulled apart.
4.The tissue can then be made into either flat surfaces or wound around a cardboard
tube to create a cylindrical rolls.
5.Many different roll sizes and sheet counts are produced on the winding machines.
6.The large roll is fed into a doctoring system and cut by a large rotating doctor blade
into individual rolls.
