TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

3. FLASHING UP PROCEDURE
(a) Check Certificate of Fitness and its validity date.
(b) Check maximum permissible working pressure which is indicated by a red
line on pressure gauge fitted.
(c) Check and close drain valves.
(d) Open water and steam cocks of water gauge glass and shut its drain cock.
(e) Clean and examine filter in feed water system.
(f) Open feed water tank outlet valve, and ensure water level in tank is at least
half the gauge glass.
(g) Check fuel oil daily service tank level and drain off any water present.
(h) Clean and examine filters in fuel oil system.
(i) Shut main steam stop valve and open air vent.
(j) Switch on power supply. Feed water pump will automatically supply water
to boiler till approximately half gauge glass.
(k) Fuel oil pump will automatically start. Fuel oil, if heavy diesel oil, will
circulate through fuel oil heater till the desired operating temperature
reached.
(l) The blower motor will start and purge furnace for at least 1-2 minutes to
clear any combustible gas accumulated in the furnace and avoid a blow
back.
(m) The burner will be ignited according to an automatic sequence, initially at
low fire rate.
(n) When steam comes out from air vent, shut off air vent and switch to high
fire rate. Steam pressure will gradually increase to normal working
pressure.
(o) Check gauge glass, safety valve, and all automatic safety devices to ensure
they are functioning normally.
(p) Open steam valve very slowly to permit warming through and draining of
the cold steam pipes to avoid damage due to water hammer.

4. TESTING OF GAUGE GLASS
When the boiler is in operation, the steam cocks A, D and water cocks B, E are
open and drain cock C is shut. FIG. 4
(a) First shut both steam and water cocks A, D, B and E. Open drain cock C
to prove that all the gauge cocks are in order. Then, with the drain cock C
still open, cocks B and E should be opened. If water blows out freely from
cock C, cocks B and E are clear. FIG. 4(A).
(b) Shut off cocks B and E and open cocks A and D with the drain cock C
still open. If steam blows out freely from cock C, cocks A and D are clear.
FIG. 4 (B).
(c) To cross test, close cocks D and B, leaving E, A and C open. If water blows
out from cock C, then E, A and the water-column are in order. FIG. 4(C).
(d) Close cocks E and A leaving D, B and C open. If steam blows out from
cock C, then D, B and the water-column are in order. FIG. 4(D).
18. 16
Possible causes of gauge glass indicating incorrect level
(a) If cocks A and D or steam passage is shut or choked, boiler pressure will
press the water level in the glass higher than the real water level of the
boiler. The water level indication in glass will, therefore, be incorrect.
(b) If cocks B and E or water passage is shut or choked, steam will condense
on upper column of glass and accumulate. The apparent water level shown
can be higher than the actual water level, causing false reading.
Water gauge glass should be tested daily at least at every change of
attendant. The safety of boiler operation relies greatly on proper functioning of
the water gauge glass.
5. LOW-WATER LEVEL CUT-OFF SWITCH
This device should be checked daily to ensure it is in normal working order.
Switch off the feed water pump, drain the float control water chamber. If boiler
is tripped off automatically, the device is in good order.
LOWER WATER LEVEL CUT-OFF

6. STEAM PRESSURE TESTING OF SAFETY VALVE
The safe operation of steam boiler depends on the correct functioning of the
safety valve. The safety valve should be lifted daily with the easing gear to
prevent sticking of valve seat and it should be pressure tested weekly as
follows:-
(a) Shut off main steam stop valve.
(b) Adjust steam pressure switch to a setting slightly higher than maximum
permissible working pressure.
(c) With boiler on maximum firing rate, observe the pressure gauge. When
steam pressure reaches m.p.w.p., safety valve will automatically open to
release steam pressure. That means safety valve is set correctly and
working. Maximum permissible working pressure can be obtained from
the Certificate of Fitness.
(d) If the safety valve does not open when the steam pressure reaches the
m.p.w.p., boiler should be stopped immediately, and the easing gear
operated to release steam and lower the boiler pressure. Call the
Appointed Examiner for examination immediately.

7. TESTING OF STEAM PRESSURE SWITCH
This switch should be checked daily to ensure it is functioning properly. During
the initial start, make sure the boiler can be tripped off automatically when
boiler pressure attains the cut-off value of the pressure switch. Cut off pressure
and differential pressure can be adjusted with the adjusting screw on top of the
switch to suit the requirement of the factory.

8. TESTING OF FLAME DETECTOR
The detector should be tested weekly to ensure it is in normal working order.
An easy method of testing is by removing the detector head from the boiler and
shielding the sensing head with hand. If boiler trips off automatically, the flame
detector is in satisfactory condition.
FLAME DETECTOR (FLAME EYE)
9. FIRE-TUBE BOILER EMERGENCIES
(a) When the boiler is steaming with water level not visible in the gauge glass,
shut off the burner immediate1y. Test the gauge glass or test cocks. If low
water level established in the boiler NEVER add water into the boiler right
away. Locate and rectify the fault, wait until the boiler has cooled down,
seek advice of an Appointed Examiner for identifying defect or damage
before flashing the boiler again.
(b) If the steam pressure exceeds the maximum permissible working pressure
without lifting of safety valve, shut off the boiler immediately. Operate the
easing gear to release steam. If safety valve still does not open auto-
matically, release steam from air vent valve and contact an Appointed
Examiner for examination and advice on repair.
22. 20
(c) Boiler water should be tested and chemically treated according to
manufacturer's schedule or on the advice of an Appointed Examiner. This
will avoid corrosion and scale formation on heating surfaces. Wastage of
furnace, fire tubes or boiler shell can develop and cause boiler explosion.
Consult an Appointed Examiner for advice.
10. HANDLING OF BOILER FIRES
(a) First raise fire alarm or shout to let all workers in the factory know of the
fire.
(b) Shut off the main power supply for boiler room. Shut off the fuel oil
isolating valve. Stop the boiler, and switch off the ventilation fan.
(c) Locate the site of fire, and check the cause and nature of fire. Use
appropriate fire extinguishers for different type of fires:─
Oil fire : foam, dry powder etc.
Electric fire : CO2, dry powder etc.
11. IMPORTANT POINTS FOR COMPLIANCE BY WORKERS
AND FACTORY OWNERS
* Don't break the seal of the safety valve, or try to adjust its setting to increase
the boiler pressure. This endangers the safety, will cause over-pressure of the
boiler and may cause boiler explosion with consequent injuries to personnel.
* All automatic safety devices such as safety valve, pressure switch and
low-water cut-off switches should be tested periodically to ensure they are in
good working condition at all times.
* If accident happens to a boiler or its auxiliary, owner must immediately stop
using the boiler and report the accident to the Authority of Boilers and
Pressure Vessels within 24 hours. The owner can be prosecuted and fined a
maximum of $10,000 for not complying this requirement.
