Mathematics

MATHEMATICS
          Mathematics is the science that deals with shapes, quantities and arrangements. Archmedes is known as the father of Mathematics (287BC-212BC). Mathematics seek and use patterns to formulates new conjuctures.They resove truth or false by using mathematical proof. Mathematics developed by counting, calculation, Measurements, Shapes and motion of physical objects. 
Definition
Mathematics has no general accepted definition. Until 18th century Aristotle defined mathematics as "the science of quantity". Many mathematicans take no interest in definition they simply say "Mathematics is what Mathematican do".
Three leading definition of mathematics today are logicist, intutionist, and formalist.
Logicist - In terms of Benjamin peirce, the definition of mathematics in terms of logic are "the science that draws necessary conclusion" and also said that " All mathematics is symbolic logic" by Mathematician Rusell.
Intutionist - L.E.J.Brouwer, defines "Mathematics is the mental activity which consists in carrying out construct one after the other".
Formalist - Haskell Curry, defines Mathematics as "the science of formal systems".
Mathematics include in many fields such as Natural science, Engineering, Medicine, Finance and Social Sciences.The Mathematics can be classified as 
1.Pure Mathematics
* Number Theory
* Algebra
* Geometry
* Arithmetic
* Combinatorincs
* Topology
* Mathematical Analysis
2.Applied Mathematics
* Calculus
* Statistics and probability
* Set theory
* Trigonometry
Rules in Mathematics
The main rules in Mathematics is BODMAS. 
*Brackets (parts of the calculation always comes first)
*Orders (numbers involving powers or squares)
*Division
*Multiplication
*Addition
*Subtraction
Skills developed by studying Mathematics
*Critical thinking

Human Factors in Designing User-Centric Engineering Solutions

Human factors play a pivotal role in the design and development of user-centric engineering solutions. The integration of human-centered design principles ensures that technology not only meets functional requirements but also aligns seamlessly with users' needs, abilities, and preferences. This approach recognizes the diversity among users and aims to create products and systems that are intuitive, efficient, and enjoyable to use. In this exploration, we will delve into the key aspects of human factors in designing user-centric engineering solutions, examining the importance of user research, usability, accessibility, and the overall user experience. User Research: Unveiling User Needs and Behaviors At the core of human-centered design lies comprehensive user research. Understanding the target audience is fundamental to creating solutions that resonate with users. This involves studying user needs, behaviors, and preferences through various methodologies such as surveys, interview...

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...
