Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

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.

REMARKS
24. Industrial Attachment Report Page 24 of 56
HAMS WASHING & DYEING LTD.
No live industry can keep place with the advance of technology without continuous
renewal & transformation of its production facilities. Existing equipments must be kept on the
defensive, compelled always to justify its tenure against the challenge of new & more modern
machines. If any piece of existing equipment fails to meet this challenge, it must be displaced,
regardless of its age or condition & regardless of whether it is physically “worn out”.
Keeping the above in view, this industry is always replacing its existing machines in
order to increase productivity & improve quality.

FUNCTIONS OF MAINTENANCE PERSONNEL
Inspection or Check-Ups:
° External inspections: Watching and detecting defects form abnormal sound,
vibration, heat, smoke etc when machine is in operation.
° Internal inspections: Inspection of parts such as gears, bushes, bearings,
tolerances in the parts etc. when machine is under pre-planned shutdowns.
° Inspections of important machines: Machines, which can disrupt whole of the
production, are delicate and require much time for the repair. Attentions are given
for inspection of these machines and schedule for inspection, cleaning lubrication
are done rigidly.
° Inspections of ordinary machines: Frequency of inspection of ordinary
machines is kept as low as they do not affect the production.
49. Industrial Attachment Report Page 49 of 56
HAMS WASHING & DYEING LTD.
Lubrication: Mechanical components like gears, bearings, bushes and other friction
surfaces etc. give good performance for long periods when they are systematically
lubricated. Systematic lubrication means the application of right type of lubricants at the
right time, at right place and in right quantity. For lubrication, a lubrication schedule
should be prepared and that should be followed strictly. Here lubrication is done
whenever is needed.
Planning and scheduling: Every preventive maintenance work should be pre-planned
in detail on the basis of the analysis done on the past records. A scheduled programme
thus prepared should be followed strictly. Thus programme should be in detail specifying
the point-requiring daily, weekly, monthly, half yearly or yearly attention.
Records and analysis: Good record keeping is essential for good maintenance, as it
helps in for casting maintenance. For this purpose following records are generally
maintained:
° Operation manual
° Maintenance and instruction manual
° History Cards and History Registers
° Spares Procurement Registers
° Spare Procurement Register
° Inspection Register
° Log books
° Defect Register etc.
Training of Maintenance personnel: For the success of maintenance a sound
training is essential for the maintenance personnel. Hence the technicians and
supervisors are trained to carry out maintenance, inspection and repaired in a systematic
way.
Storage of Spare Parts: Sometimes machine remains idle for want of spare parts for
considerable time and thus it affects considerable loss of production. Hence it is essential
to keep the spare parts so as to avoid loss of production.
50. Industrial Attachment Report Page 50 of 56
HAMS WASHING & DYEING LTD.
Maintenance practices are made from the following ways:
Capital replacement: capital replacement is undertaken if analysis reveals that the
retention of equipment no more remains an economical proposition.
Provision of stand-by-capacity: Stand by capacity is often provided for items of
equipment that we are critical to production. It is sometimes an economical maintenance
practice to install such spare capacity to be put into operation while the original unit is
under repair or is over-hauled.
Break-down maintenance: Break-down maintenance practice allows a machine or
any other facility to run without much of routine attention, till it actually breaks down to
be then put back into commission.
Scheduled maintenance: Scheduled maintenance system provides for inspection,
overhaul lubrication, and servicing of certain machines at predetermined dates. Over-
hauling of machines, cleaning of tanks and white washing of buildings is normally done
in this manner.
Planned maintenance: Planned maintenance visualise the work contained in a future
job determines the best method to be adopted and skills required for its execution;
estimates the time, material and costs involved assigning jobs to individuals;
programmes the work to specific time periods on the basis of priority and after
ascertaining production requirements; arranges for availability of material tools and man-
power and for release of machines in time.
Preventive maintenance: It consists of routine actions taken in a planned manner to
prevent breakdowns and to ensure operational accuracy to the extent it is economically
and practically possible to do so.

CAPACITY & OTHER TECHNICAL DETAILS
WATER: Water is supplied by pump. Pump supplies water on the basis of pressure.
Pump pressure ranges 0-10 bar. The pump is operated at 2-4-bar pressure. 3 motors are
used for uniform water supply. These are automatic on-off system motor. When the
pressure is reduced to the desired level (2 bars) then the motor is turned on. Similarly
when the pressure is above the desired level (4 bars) then the motor is turned off. So, it
has variable water supply capacity & supplies water as required.
The water, which is used for cooling, is brought to a tank & again supply by a pump.
There are 3 deep tube wells used in this project. Water is directly used in washing &
dyeing & other subsequent process.
02 PCs. Deep Tube wells are submersible, Made in ITALY, BG brand with 30 Horse
Power.
01 PC. Deep Tube well is submersible, Sigma branded, Made in ITALY with 42 Horse
Power.
STEAM: Heat generation is a very important factor for washing and dyeing process.
Steam is a very efficient & easy way to transfer heat. There is a boiler to generate steam.
By pipe line the generated steam is supplied to the washing and dyeing machines &
where it is necessary. The boiler has the capacity to generate steam 1.5 Tons/Hr.
Technical details about the boiler:

REMARKS
There is problem with water supply in the company. The supply of water is not
sufficient, which create problem in washing and dyeing. The quality of water is not up to the
level. The hardness & presence of iron in water is high. A water treatment plant is very essential

to continue the production without disturb & to increase the production.
The generator of the industry is too old to supply the electricity fluently. Sometimes it
trip without any warning. So, it’s necessary to have a new generator for the industry.
The boiler also very old to maintain it high bar pressure. It should be replaced with
modern boiler for better service.
