A number system is a writing system that uses symbols to represent quantitative information. The main types of number systems are decimal, binary, hexadecimal, and octal. The decimal system uses the digits 0-9 with a base of 10. The binary system uses only the digits 0 and 1 and is used in computer applications. The hexadecimal system has a base of 16 and uses the digits 0-9 and the letters A-F. The octal system has a base of 8 and uses the digits 0-7.

A number system is a way of representing and organizing numbers. There are several types of number systems, including:
1. Binary Number System: uses only two digits, 0 and 1, to represent numbers.
2. Decimal Number System: uses ten digits, 0 to 9, to represent numbers. It is the most commonly used number system in daily life.
3. Octal Number System: uses eight digits, 0 to 7, to represent numbers.
4. Hexadecimal Number System: uses sixteen digits, 0 to 9 and A to F, to represent numbers.
5. Scientific Notation: represents numbers in a compact form by expressing them as a product of a power of 10 and a number between 1 and 10.
Each number system has its own advantages and disadvantages, and they are used in different applications based on their suitability.
Here are some important things to know about number systems:
1. Number systems are used to represent and store numerical values in computers and other digital devices.
2. The choice of a number system depends on the requirement of a specific application, and each number system has its own advantages and disadvantages.
3. The decimal number system is widely used in daily life, but binary and hexadecimal number systems are more commonly used in computer programming and electronic devices.
4. Converting between different number systems requires an understanding of the place value system, which assigns different values to each digit based on its position in the number.
5. The binary number system is particularly important to understand in the context of computer science, as it is used to represent data in the form of bits, and all data processed by computers is ultimately represented as binary numbers.
6. The hexadecimal number system is commonly used in computer programming because it is more compact and easier to read than binary or decimal representations of large numbers.
7. The octal number system is used less frequently in modern computer systems, but it is still used in some specialized applications.

A number system is a method for writing and representing numbers using digits or symbols in a consistent way. It allows unique representation of numbers and performing arithmetic operations. The main types of number systems are decimal, binary, octal, and hexadecimal, which use bases of 10, 2, 8, and 16 respectively. Number systems are used daily for tasks like making phone calls, budgeting, cooking, using elevators, shopping, and more. [/SUMMARY]

Data representation
1) A computer manipulates data by storing, retrieving, and processing it. Machine code, consisting of binary numbers, is the lowest-level language directly understood by computers.
2) There are four main number systems for representing data in computers: decimal, binary, octal, and hexadecimal. Each has a different base - 10 for decimal, 2 for binary, 8 for octal, 16 for hexadecimal.
3) Converting a decimal number to another base involves repeatedly dividing the number by the new base's value and recording the remainders as the new number in that base. For example, converting 17 to binary is (10001)2.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
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

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.

Advanced control scheme of doubly fed induction generator for wind turbine us...
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.

NUMBER SYSTEM.pptx
- 1. NUMBER SYSTEM A NUMBER SYSTEM IS A WRITING SYSTEM FOR EXPRESSING NUMBERS . IT IS USED TO REPRESENT INFORMATION IN QUANTITATIVE FORM.
- 2. Types of Number System • THERE ARE MAIN 4 TYPES OF NUMBER SYSTEM 1. DECIMAL NUMBER SYSTEM 2. BINARY NUMBER SYSTEM 3. HEXADECIMAL NUMBER SYSTEM 4. OCTAL NUMBER SYSTEM
- 3. DECIMAL NUMBER SYSTEM DECIMAL NUMBER SYSTEM CONSISTS OF TEN DIGITS (0 TO 9) TO REPRESENT A NUMBER WITH THE BASE 10. THE NUMBER IS EXPRESSED IN BASE 10 WHERE EACH VALUE IS DENOTED BY 0 OR FIRST NINE POSITIVE INTEGARS . EX . 435 , 6543 ,5442 , ETC.
- 4. Binary Number System A BINARY NUMBER SYSTEM IS ONE OF THE FOUR TYPES OF NUMBER SYSTEM. IN COMPUTER APPLICATIONS, WHERE BINARY NUMBERS ARE REPRESENTED BY ONLY TWO SYMBOLS OR DIGITS, I.E. 0 (ZERO) AND 1(ONE). THE BINARY NUMBERS HERE ARE EXPRESSED IN THE BASE-2 NUMERAL SYSTEM. FOR EXAMPLE, (101)2 IS A BINARY NUMBER.
- 5. Hexadecimal Number System THE HEXADECIMALNUMBERSYSTEM IS A ANOTHER TYPE OF NUMBER SYSTEM, THAT HAS A BASE VALUE EQUAL TO 16. IT IS ALSO PRONOUNCED SOMETIMES AS ‘HEX’. HEXADECIMAL NUMBERS ARE REPRESENTED BY ONLY 16 SYMBOLS. THESE SYMBOLS OR VALUES ARE 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E AND F.
- 6. Octal number system A NUMBER SYSTEM WHICH HAS ITS BASE AS ‘EIGHT’ IS CALLED AN OCTAL NUMBER SYSTEM. IT USES NUMBERS FROM 0 TO 7. LET US TAKE AN EXAMPLE, TO UNDERSTAND THE CONCEPT. AS WE SAID, ANY NUMBER WITH BASE 8 IS AN OCTAL NUMBER LIKE 248, 1098, 558, ETC.
