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.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
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.

2.1 Structure of Raspberry Pi
6. 6
Step 1:
Plug in a monitor (via HDMI) and a keyboard and mouse
(via USB).
● Need an interface to the device.
Step 2: Get an operating system.
● Raspberry Pi needs an OS.
● OS image must be present on the micro SD card.
Refer : https://youtu.be/y45hsd2AOpw
2.2 Installation
7. 7
Installing an Operating System
Use New Out- Of-Box Software (NOOBS)
● Normally comes preinstalled on micro SD bundled with Raspberry Pi boards.
● Otherwise, download it for free from https://projects.raspberrypi.org/en/projects/noobs-install.
● If NOOBS is not preinstalled on micro SD, you’ll need to:
1. Format the micro SD(need an SD reader)
2. Extract the NOOBS download
3. Put it on the micro SD
8. 8
● From this pop up window user can select
any OS , but most recommended one is
Raspbian.
● Like this way NOOBS will install an
operating system on your microSD card.
9. 9
Raspi- Configuration
● Raspi- config is a tool which lets you set up various setup/boot options for the Raspberry
PI.
● It will run automatically when you boot the Raspberry Pi with a new micro SD card for the
first time.
10. 10
❖ Expand Filesystem - Reformats your micro SD card filesystem to allow access to all the memory.
❖ Change User Password - Raspberry Pi starts with one user account ( username: “pi”) with a
default password (“raspberry”).
❖ Enable boot to Desktop/Scratch
● Console is default boot option.
● Desktop is the graphic interface.
● Scratch is a programming environment for kids.
If you use desktop you can invoke console too. But you use console , then you can only get
console.
11. 11
● There are 40 pins in Raspberry Pi 3 B+ model.
● Basically there are,
○ power and ground pins
○ GPIO pins
○ Other multi functional pins
● Anyhow there are 2 ways to number these
pins.
1. GPIO.BOARD
Number of pins in their order on the
board.(as shown under Pin#)
1. GPIO.BCM
The Broadcom SoC number.(
No.shown after GPIO)
● In here we used board numbering system.

Set pin mode
➔ Set a pin to act as an INPUT or OUTPUT pin.
◆ GPIO.set up (pin no, GPIO.OUT)
Ex: GPIO.set up (13, GPIO.OUT)
◆ GPIO.set up (pin no, GPIO.IN)
Ex: GPIO.set up (13, GPIO.IN)
Pin Direction
➔ Assign a value to pins set as OUTPUT pins. (3.3v / 0 v)
◆ GPIO.output(pin no, True)
Ex:GPIO.output(13, True)
◆ GPIO.output(pin no, False)
Ex:GPIO.output(13, False)
Let’s begin with GPIO pins

14. Reading an input pins
GPIO.setup( pin no , GPIO.IN)
value = GPIO.input(pin no.)
● This can read value on input pin.
● But in Raspberry pi there is no analog to digital converter. So it can only read digital
values.

Period (T) = time for one cycle
Freequency (f) = number of cycles per second
2.4 Pulse Width Modulation (PWM)
f = 1 / T
16. 16
● Pulse - one cycle
● pulse width - HIGH/ON period of pulse
● Raspberry Pi generates only digital signals as high or low. But there are some devices,
which respond to analog. But we can't generate analog from this. So, one way to deal with
that is to send a pulse width modulated signal. User can make the signal go from high
to low really fast.
Duty Cycle = Pulse width / Period * 100%
17. 17
● Imagine these are duty
cycles of pulses for three
iLEDs. In here the pulses
have with same frequency
as well as same time period.
● Only difference is their duty
cycles. It make differences in
LEDs intensity as follows:
L2>L1>L3

PWM Initialization
● Mark pin for PWM.
pwm_obj = GPIO.PWM( pin no ,
frequency)
● Start generating PWM signal
according to given duty cycle(0-100).
pwm_obj.start(duty cycle)
PWM Control
● Assign new duty cycle.
pwm_obj.ChangeDutyCycle(50)
Frequency Control
● Need to do it manually.
while True:
GPIO.output( pin no. , True)
time.sleep(0.5)
GPIO.output( pin no. , False)
time.sleep(0.5)
● This will give a 1Hz pulse.

● A compact implementation of
python 3.
● Created for usage in
microcontrollers.
● Originally Created by Australian
programmer Damien George.
● Only include subset of python
libraries.
➔ Basically it’s a stripped and trimmed
version of python in order to work
with embedded devices with limited
resources.
➔ Support many devices like ESP32,
ESP8266, PyBoard, Wipy-pycom

Reading an input pins
1. Reading Digital values
P2= Pin (0, Pin.IN) #create input pin on GPIO2
print(P2.value()) #get value, 0 or 1
1. Reading Analog values
● ADC functionality available on pins 32-39.
from machine import ADC
adc = ADC(Pin(32)) # create ADC object on ADC pin
adc.read() # read value, 0-4095 across voltage range 0.0v - 1.0v
adc.atten(ADC.ATTN_11DB) # set 11dB input attenuation (voltage range roughly 0.0v - 3.6v)
adc.width(ADC.WIDTH_9BIT) # set 9 bit return values (returned range 0-511)
adc.read() # read value using the newly configured attenuation and width
30. 30
ADC.atten(attenuation)
This method allows for the setting of the amount of
attenuation on the input of the ADC. The possible
attenuation options are:
● ADC.ATTN_0DB: 0dB attenuation, gives
a maximum input voltage of 1.00v - this
is the default configuration
● ADC.ATTN_2_5DB: 2.5dB attenuation,
gives a maximum input voltage of
approximately 1.34v
● ADC.ATTN_6DB: 6dB attenuation, gives
a maximum input voltage of
approximately 2.00v
● ADC.ATTN_11DB: 11dB attenuation,
gives a maximum input voltage of
approximately 3.6v
ADC.width(width)
This method allows for the setting of the number of
bits to be utilised and returned during ADC reads.
Possible width options are:
● ADC.WIDTH_9BIT: 9 bit data
● ADC.WIDTH_10BIT: 10 bit data
● ADC.WIDTH_11BIT: 11 bit data
● ADC.WIDTH_12BIT: 12 bit data - this is
the default configuration
32. 32
● PWM can be enabled on all output-enabled pins.
● Currently the duty cycle has to be in the range of 0-1023.
from machine import Pin, PWM
pwm0 = PWM(Pin(0)) # create PWM object from a pin
pwm0.freq() # get current frequency
pwm0.freq(1000) # set frequency
pwm0.duty() # get current duty cycle
pwm0.duty(200) # set duty cycle
pwm0.deinit() # turn off PWM on the pin
pwm2 = PWM(Pin(2), freq=20000, duty=512) # create and configure in one go
