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.

NUMBER SYSTEM
&
DEFINATIONS
3. Digital Number System
Many number system are in use in digital technology. The
most common are the decimal, binary, octal, hexadecimal
system.
4. OTHER NUMBER SYSTEM
Base-2 binary system
Base3 tritary system Base-11 undecimal system
Base-4 quaternary system Base-12 duodecimal system
Base-5 quinary system Base-13 tridecimal system
Base-6 senary system Base-14 tetradecimal system
Base-7 septenary system Base-15 pentadecimal system
Base-8 octal system Base-16 hexadecimal system
Base-9 nonary system
Base-10 decimal system Base-20 The vigesimal system
Base-36 hexatridecimal system
5. The decimal system is composed of
10 symbols. These 10 symbols are
0,1,2,3,4,5,6,7,8,9; using these
symbols as digits of a number of a
number. The decimal system also
called base 10 system because it has
10 digits, has evolved naturally as a
result of the fact that people have 10
finger .
In fact, the word “digit” is derived
from the Latin word for “finger.”
6. Positional Notation
The decimal system is a positional –value system in which the
value of a digit depends on its position….
642 in base 10 positional notation is:
6 x 102 = 6 x 100 = 600
+ 4 x 101 = 4 x 10 = 40
+ 2 x 10º = 2 x 1 = 2 = 642 in base 10
The power
indicates
the position of
the number
7. MSD & LSD
Stands for Most significant digit and least significant digit
respectively e.g. 2735.214.
2 carries the most weight or value so 2 is MSD and 4 carries the
least weight or value so 4 is LSD .
8. CONVERSION
Decimal to binary , octal and hexadecimal
Conversion from decimal system into other system. It involves using
successive division by the radix until the dividend reaches 0. At each division, the remainder
provides a digit of the converted number, starting with the least significant digit.
For example: convert 3710 to binary
37 / 2 = 18 remainder 1 (least significant Bit)
18 / 2 = 9 remainder 0
9 / 2 = 4 remainder 1
4 / 2 = 2 remainder 0
2 / 2 = 1 remainder 0
1 / 2 = 0 remainder 1 (most significant Bit)
The resulting binary number is: 100101 THAT WE START FROM MSB TO LSB
9. EXAMPLE: CONVERT (177)10 TO OCTAL
Conversion of decimal fraction to octal fraction is carried out in the same
manner as decimal to binary except that now the multiplication is carried
out by 8.
SOLUTION:
177 / 8 = 22 remainder is 1
22 / 8 = 2 remainder is 6
2 / 8 = 0 remainder is 2
The resulting binary number is: (261)8
11. What if 642 has the base of 13?
6 x 132 = 6 x 169 = 1014
+ 4 x 131 = 4 x 13 = 52
+ 2 x 13º = 2 x 1 = 2
2+52+1014 = 1068 in base 10
642 in base 13 is equivalent to 1068
in base 10
12. Binary Number System
Base = 2
2 digits { 0, 1 }, called binary digits or “bits”
Weights
Weight = (Base) Position
Formal Notation
Groups of bits 4 bits = Nibble
8 bits = Byte
13. Converting Binary to Decimal
What is the decimal equivalent of the binary number 1101110?
1 x 26 = 1 x 64 = 64
+ 1 x 25 = 1 x 32 = 32
+ 0 x 24 = 0 x 16 = 0
+ 1 x 23 = 1 x 8 = 8
+ 1 x 22 = 1 x 4 = 4
+ 1 x 21 = 1 x 2 = 2
+ 0 x 2º = 0 x 1 = 0
= 110 in base 10
14. Conversion of binary to octal and hex Conversion
Conversion of binary numbers to octal and hex simply requires
grouping bits in the binary numbers into groups of three bits for
conversion to octal and into groups of four bits for conversion to
hex.
Groups are formed beginning with the LSB and progressing to the
MSB.
10101011 10 101 011

16. Conversion of binary to hexadecimal
Convert the binary number 0110101110001100 to hexadecimal
Divide into groups of 4 digits 0110 1011 1000 1100
Convert each group to hex digit 6 B(11) 8 C(12)
6B8C in hex
17. Calculator Hint
If you use a calculator to perform the divisions by 2, you
can tell whether the remainder is 0 or 1 by whether or not
the result has a fractional part. For instance, 25/2 would
produce 12.5. Since there is a fractional part (.5 ), the
remainder is a 1. If there were no fractional part, such as
12/2=6 then the remainder would be 0.
18. Octal refers to a numbering system that has a base
of eight. This means it only uses the eight numerals
0,1,2,3,4,5,6,7 for each digit of a number.
19. Conversion:
Converting Octal to Decimal:
What is the decimal equivalent of the octal number 642?
6 x 82 = 6 x 64 = 384
+ 4 x 81 = 4 x 8 = 32
+ 2 x 8º = 2 x 1 = 2
= 418 in base 10
Example: convert (632)8 to decimal
= (6 x 82) + (3 x 81) + (2 x 80)
= (6 x 64) + (3 x 8) + (2 x 1)
= 384 + 24 + 2
= (410)10
20. 1) Convert (634)8 to binary equivalent?

21. Calculator Hint
If a calculator is used to perform the division , the result will
include a decimal fraction instead of a remainder. The
remainder can be obtained, However, by multiplying the
decimal fraction by 8, for example 266/8 produces 33.25.The
remainder becomes 0.25 * 8 =2.
We need this hint when we convert decimal system into octal
system..
26. DEFINATIONS:
Digital Signal: A digital
signal is a physical
signal that is a representation
of a sequence of discrete values.
Analog Signal: Analog signal
is a continuous signal w.r.t
time. An Analog signal have
its changing value at every
instant of time
27. Active high and low:
Active high: It can call as positive
logic. The high voltage +5v
represent logic high that is 1 and
lower 0v represent the logic low
that is 0.
Active low: it can call as negative
logic . The higher voltage
represent as logic low that is o
and lower voltage represent as
logic high that is 1..
28.
29. Duty Cycle
A duty cycle is the percentage of
one period in which a signal is active. A
period is the time it takes for a signal to
complete an on-and-off cycle. As a
formula, a duty cycle may be expressed as:
D=T/P *100
where is the duty cycle, is the time the
signal is active, and is the total period of
the signal. Thus, a 50 % duty cycle means
the signal is on 50 % of the time but off
50% of the time.
