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.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Classification of Microprocessors
Classification on the basis of Hardware and architecture:
RISC Processor: RISC stands for Reduced Instruction Set Computer. It is designed to reduce
the execution time by simplifying the instruction set of the computer. Using RISC processors, each
instruction requires only one clock cycle to execute results in uniform execution time.
Examples-
Power PC: 601, 604, 615, 620
DEC Alpha: 210642, 211066, 21068, 21164
MIPS: TS (R10000) RISC Processor
PA-RISC: HP 7100LC
SISC Processor: CISC stands for Complex Instruction Set Computer. It is designed to
minimize the number of instructions per program, ignoring the number of cycles per instruction.
The emphasis is on building complex instructions directly into the hardware.
The compiler has to do very little work to translate a high-level language into assembly level
language/machine code because the length of the code is relatively short, so very little RAM is
required to store the instructions.
Examples-
IBM 370/168
VAX 11/780
Intel 80486

Special Processor: These are the processors which are designed for some special purposes.
Few of the special processors are briefly discussed –
Coprocessor: A coprocessor is a specially designed microprocessor, which can handle its particular
function many times faster than the ordinary microprocessor.
For example − Math Coprocessor.
Input/output Processor: It is a specially designed microprocessor having a local memory of its
own, which is used to control I/O devices with minimum CPU involvement.
For example −
DMA (direct Memory Access) controller
Keyboard/mouse controller
Transputer (Transistor Computer): A transputer is a specially designed microprocessor with its
own local memory and having links to connect one transputer to another transputer for inter-
processor communications.
DSP (Digital Signal Processor): This processor is specially designed to process the analog signals
into a digital form. This is done by sampling the voltage level at regular time intervals and
converting the voltage at that instant into a digital form. This process is performed by a circuit
called an analogue to digital converter, A to D converter or ADC.

Integrated Circuits
An integrated circuit (IC), sometimes called a chip or microchip, is a semiconductor wafer on which
thousands or millions of tiny resistors, capacitors, and transistors are fabricated. An IC can function
as an amplifier, oscillator, timer, counter, computer memory, or microprocessor. A particular IC is
categorized as either linear analog or digital, depending on its intended application.

Chapter-5
History of Integrated Circuits
Integrated circuits developed from transistor technology as scientists sought ways to build more
transistors into a circuit. The first integrated circuits were patented in 1959 by two Americans-Jack
Kilby, an engineer, and Robert Noyce, a physicist-who worked independently. Integrated circuits
had caused a great revolution in electronics in the 1960's as transistors had caused in 1950's. The
circuits were first used in military equipment and space craft and helped make possible the first
human space flights of the 1960's.
Fig.5: Jack Kilby's original integrated circuit
Most integrated circuits are small pieces, or “chips,” of silicon, perhaps (0.08 to 0.15 sq in) long, in
which transistors are fabricated. Photolithography enables the designer to create tens of thousands
of transistors on a single chip by proper placement of the many n-type and p-type regions. These are
interconnected with very small conducting paths during fabrication to produce complex special-
purpose circuits. Such integrated circuits are called monolithic because they are fabricated on a
single crystal of silicon. Chips require much less space and power and are cheaper to manufacture
than an equivalent circuit built by employing individual transistors. Integrated circuits (ICs) make
the microcomputer possible; without them, individual circuits and their components would take up
far too much space for a compact computer design.
13. P a g e | 13
Advantage of Integrated Circuits:
The major advantages of integrated circuits over those made by interconnecting discrete
components are as follows:
Extremely small size – Thousands times smaller than discrete circuits. It is because
of fabrication of various circuit elements in a single chip of semiconductor material.
Very small weight owing to miniaturised circuit.
Very low cost because of simultaneous production of hundreds of similar circuits on
a small semiconductor wafer. Owing to mass production of an IC costs as much as
an individual transistor.
More reliable because of elimination of soldered joints and need for fewer
interconnections.
Lower power consumption because of their smaller size.
Easy replacement as it is more economical to replace them than to repair them.
Increased operating speed because of absence of parasitic capacitance effect.
Close matching of components and temperature coefficients because of bulk
production in batches.
Improved functional performance as more complex circuits can be fabricated for
achieving better characteristics.
Greater ability of operating at extreme temperatures.
Disadvantages of Integrated circuits:
The major disadvantages of integrated circuits over those made by interconnecting discrete
components are as follows:
Limited power rating as it is not possible to manufacture high power (say greater
than 10 W) ICs.
Need of connecting inductors and transformers exterior to the semiconductor chip as
it is not possible to fabricate inductor and transformers on the semiconductor chip
surface.
Operation at low voltage as ICs function at fairly low voltage.
Quite delicate in handling as these cannot withstand rough handling or excessive
heat.
Need of connecting capacitor exterior to the semiconductor chip as it is neither
convenient nor economical to fabricate capacitances exceeding 30pF. Therefore, for
higher values of capacitance, discrete components exterior to IC chip are connected.
High grade P-N-P assembly is not possible.
Low temperature coefficient is difficult to be achieved.
Large value of saturation resistance of transistors.
Voltage dependence of resistor and capacitors.

Digital Logic Families
A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates
constructed using one of several different designs, usually with compatible logic levels and power
supply characteristics within a family.
Logic Families indicate the type of logic circuit used in the IC.
The main types of logic families are:
TTL(Transistor Transistor Logic)
CMOS (Complementary MOS)
ECL (Emitter Coupled Logic)
MOS(Metal-Oxide Semiconductor)
Transistor Transistor Logic (TTL)
Transistor–transistor logic (TTL) is a class of digital circuits built from bipolar junction
transistors (BJTs) and resistors. It is called transistor–transistor logic because transistors
perform both the logic function (e.g., AND) and the amplifying function (compare with
resistor–transistor logic (RTL) and diode–transistor logic (DTL)).

Emitter Coupled Logic (ECL)
In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar
transistor logic family. ECL uses an overdriven BJT differential amplifier with single-ended
input and limited emitter current to avoid the saturated (fully on) region of operation and its
slow turn-off behavior.

Metal-Oxide Semiconductor (MOS)
It is a three-layer sandwich of a metal, an insulator (usually an oxide of the substrate), and a
Semiconductor substrate, used in integrated circuits.

Positive and Negative Logic
The binary signal at the input and the output of any gate has one of the two values, except during
the transition one signal value represents logic 1 (one) and other logic 0 (zero), depending upon the
positive and negative logic the higher signal level ‘H’ and lower signal level ‘L’ differs.
The table below shows the two assignments that define positive and negative logic systems.
Positive Logic Negative Logic
H = 1 H = 0
L = 0 L = 1
A logical operation has two different implementations depending on if positive or negative logic is
used:

Characteristics of Logic Families
The main characteristics of Logic families include:-
Fan-Out
Power Dissipation
Propagation Delay
Noise Margin
Fan-Out:- It specifies the number of standard loads that the output of the gate can drive without
impairment of its normal operation.
Power Dissipation: - It refers the power consume by the gate which must be available from the
power supply.
Propagation delay: -It is the average transition delay time for the signal to propagate from input to
output when the signals change in value.
Noise Margin: - It refers the limit of the noise voltage which may be present without impairing the
proper operation of the circuit.
