BSIT-3R2 September, 2015 Ultrasonic Radar System By: GROOk Contact Information: Abstract: This project is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. Keywords: I. Instroduction The idea of making an Ultrasonic RADAR appeared to us while viewing the technology used in defense, be it Army, Navy or Air Force and now even used in the automobiles employing features like automatic/driverless parking systems, accident prevention during driving etc.
Radar systems come in a variety of sizes and have different performance specifications. Some radar systems are used for air-traffic control at airports and others are used for long range surveillance and early-warning systems. A radar system is the heart of a missile guidance system. Small portable radar systems that can be maintained and operated by one person are available as well as systems that occupy several large rooms.
The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems; marine radars to locate landmarks and other ships; aircraft anti-collision systems; ocean surveillance systems, outer space surveillance and rendezvous systems; meteorological precipitation monitoring; altimetry and flight control systems; guided missile target locating systems; and ground-penetrating radar for geological…...

...Accountability and Ethics Computer Addiction and Cyber Crime Nick Nykodym The University of Toledo Sonny Ariss The University of Toledo Katarina Kurtz The University of Toledo This research explores the relationship between computer addiction and cyber crime. There is evidence of computer addiction in medical settings, scholarly journals and legal proceedings. Reviewing the history of computer addiction has shown that computer addiction can be related to cyber crime. This paper will define computer addiction, show how various cyber crimes, especially those against businesses and organizations, can be motivated by computer addiction and propose further research on how managers can deal with cyber crime in a business, by recognizing addictive behaviors and computer addiction in their employees. HISTORY OF COMPUTER ADDICTION Computer addiction is an idea that has been in existence for years. Since the 1970s, avid computer programmers and hackers have been called “addicts” by both psychologists and the general public (Reed, 2002, p. 135). In 1976, Weizenbaum wrote about computer programmers who could sit and work at their computer terminals for twenty or thirty hours at a time. This behavior however, was viewed at the time as useful to technology and society. Computers, once seen as huge government machines that only very knowledgeable people could use, transformed into user-friendly tools that could be used by the everyday person. It became more common to see computers in......

...Computers types I, Computer: Definition A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are: § It responds to a specific set of instructions in a well-defined manner. § It can execute a prerecorded list of instructions (a program). § It can quickly store and retrieve large amounts of data. Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. Modern computers are electronic and digital. The actual machinery (wires, transistors, and circuits) is called hardware; the instructions and data are called software. All general-purpose computers require the following hardware components: § Central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions organized in programs ("software") which tell the computer what to do. § Memory (fast, expensive, short-term memory): Enables a computer to store, at least temporarily, data, programs, and intermediate results. § Mass storage device (slower, cheaper, long-term memory): Allows a computer to permanently retain large amounts of data and programs between jobs. Common mass storage devices include disk drives and tape drives. § Input device: Usually a keyboard and mouse, the input device is the conduit through which data and instructions enter a computer. § Output device: A display screen, printer, or other device that lets you see what the computer has accomplished.

...Computers in Our World Our world is constantly evolving. The only thing in life that is constant is change, and Computers are no different. Even though computers have only existed in the last seventy years, many believe computers have changed the world more than any other technological advance. Over the past seventy years, computers have made a quick evolution into our world with several major advancements. Just as with all things, however, there was a beginning to the computer generation. Computers were invented to solve “complex mathematical problems using calculators within a computer(De la Bedoyere,1). Computers now can do anything within a large box. A desktop computer has many external parts joined together. A computer consist of a mother board,the motherboard controls and processes what is typed and clicked and programs running. The middle of the motherboard consist of all the work being processed. Including work and data which is sent through the motherboard to the Central Processor unit (CPU). The computer has to hold memory also to save things within computers. The Ram is a major component in saving information but only works when the computer, is running. The reason a Ram is used is to save and store information,so that when it is being worked on it wont be erased. A Computer also has external and internal drives that can read information. When the computer came out for personal use, it made it better for communication possibilities(ceruzzi,6,7) 1939 was an......

... THE HISTORY OF COMPUTER One of the earliest machines designed to assist people in calculations was the abacus which is still being used some 5000 years after its invention. In 1642 Blaise Pascal (a famous French mathematician) invented an adding machine based on mechanical gears in which numbers were represented by the cogs on the wheels. Englishman, Charles Babbage, invented in the 1830's a "Difference Engine" made out of brass and pewter rods and gears, and also designed a further device which he called an "Analytical Engine". His design contained the five key characteristics of modern computers:- 1. An input device 2. Storage for numbers waiting to be processed 3. A processor or number calculator 4. A unit to control the task and the sequence of its calculations 5. An output device Augusta Ada Byron (later Countess of Lovelace) was an associate of Babbage who has become known as the first computer programmer. An American, Herman Hollerith, developed (around 1890) the first electrically driven device. It utilised punched cards and metal rods which passed through the holes to close an electrical circuit and thus cause a counter to advance. This machine was able to complete the calculation of the 1890 U.S. census in 6 weeks compared with 7 1/2 years for the 1880 census which was manually counted. In 1936 Howard Aiken of Harvard University convinced Thomas Watson of IBM to invest $1 million in the development of an electromechanical version of Babbage's......

...CHAPTER 1 INTRODUCTION TO INFORMATION TECHNOLOGY 1.1 Introduction Modern civilization has become so complicated and sophisticated that to survive one has to be competitive. This compels people to keep themselves informed of all types of happening in the society. And this in turn entails the need for an infrastructure of information. This is the point where information technology or IT becomes most important, as it is the infrastructure that allows us to get information accurately and in time. Before we define information technology, it is important to understand the notion of Data, Information, Technology, and Knowledge. In everyday conversation, people use the terms data and information interchangeably. However, some computer professional make a distinction between the two terms. Data It is the words, numbers, letters, symbol, sound, video and graphics that describe people, events, things and ideas. It is raw facts about people, objects, and events that have little or no meaning. It is the raw material used to create useful information. It becomes information when you use it as the basis for initiating some action or for making a decision. Information It is defined as the words, numbers, letters, symbol, sound, video and graphics used as the basis for human action or decisions. It is data that have been processed and presented in a form suitable for human interpretation, often with the purpose of revealing trends or patterns that can be used in decision-making. It is data...

...Computer Computer A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. Contrary to popular belief, computers existed from antiquity. Any tool used for calculation could be referred to as a computer. The earliest computers were tally sticks in use since around 20,000 BC. Mechanical analog computers started appearing in first century and were used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small...

...ages before, when there were no computers or any other technologies. So much we have advanced that now every information is just a click away and is in your hands 24/7. All this advancement was possible only with the introduction of a small device called the “Computer”. Computers Image Curtsey: Basically, computer is a device that accepts the message by the imputer and processes this message and stores the information at the storage devices and later gives an output of the message through the output devices. A simple explanation of the computer. Normally, a computer consists of a processing unit called the Central Processing Unit or the CPU and a form of memory. In the years between 1940 and 1945 were the first electronic digital computers developed. The initial sizes were as big as a room and consumed power as much as today’s personal computers. Initially, computer was related to a person who carries out calculations or computations and as such the word computer was evolved in 1613 and continued till the end of 19th century. Later it as re-described as a machine that carries computations. The early computers were limited in their functions. It was the fusion of automatic calculation and programmability that produced the first computers that were recognized in 1837. Charles Babbage in 1837 was the first to introduce and design a fully programmed mechanical computer, his analytical engine. Due to......

Computer Classification

...CLASSIFICATION OF COMPUTERS By the type of data they manipulate · Digital computers. A computer that stores data in terms of digits (0's and 1's) and proceeds in discrete steps from one state to the next. The states of a digital computer typically involve binary digits which may take the form of the presence or absence of magnetic markers in a storage medium, on-off switches or relays. In digital computers, even letters, words and whole texts are represented digitally. They have the ability to store large quantities of data. · Analogue computers. A computer that uses electrical or mechanical phenomena to model the problem being solved, or more generally by using one kind of physical quantity to represent another. They perform arithmetic operations and logic comparison by measuring changes in physical magnitude e.g. electronic voltage, pressure change, temperature changes etc. · Hybrid computers. Are designed by interconnecting the digital computer and analog computer's element directly into one processor using a suitable interfacing circuitry. I.e. both the digital and analog features are built within the same computer processor. They are advantageous in that they combine both the functional capabilities of the digital and analogue computers, though they are more expensive By the purpose for which they are designed for · Special purpose or dedicated computers A computer that is designed to operate on a restricted class of problems. They carry out special processing......

...Assembly Language Programming Lecture Notes Delivered by Belal Hashmi Compiled by Junaid Haroon Preface Assembly language programming develops a very basic and low level understanding of the computer. In higher level languages there is a distance between the computer and the programmer. This is because higher level languages are designed to be closer and friendlier to the programmer, thereby creating distance with the machine. This distance is covered by translators called compilers and interpreters. The aim of programming in assembly language is to bypass these intermediates and talk directly with the computer. There is a general impression that assembly language programming is a difficult chore and not everyone is capable enough to understand it. The reality is in contrast, as assembly language is a very simple subject. The wrong impression is created because it is very difficult to realize that the real computer can be so simple. Assembly language programming gives a freehand exposure to the computer and lets the programmer talk with it in its language. The only translator that remains between the programmer and the computer is there to symbolize the computer’s numeric world for the ease of remembering. To cover the practical aspects of assembly language programming, IBM PC based on Intel architecture will be used as an example. However this course will not be tied to a particular architecture as it is often done. In our view such an......
