  • The fundamental value proposition of computer systems has long been their potential to automate well-defined repetitive tasks. With the advent of distributed computing, the Internet and World Wide Web (WWW) technologies in particular, the focus has been broadened. Increasingly, computer systems are seen as enabling tools for effective long distance communication and collaboration. Colleagues (and programs) with shared interests can work better together, with less respect paid to the physical location of themselves and the required devices and machinery....

  • Natural language instructions, though prevalent in many spheres of communication, have only recently begun to receive attention within computational linguistics[5]. Instructions are often accompanied by language intended to signal repetition of the action that they instruct. In order to develop a system that is able to understand instructions, with the goal of executing them, it is necessary to investigate what is meant by various types of repetition, and the different ways in which repetition can be expressed. ...

  • Have you ever noticed the visual harmory of a well design home? Its lines, shapes and colors flow from room to room and create a beautiful whole. Harmony means repetition; this fabric reappears there; a hallway line designing homes since 1969 and knows that repetition ofline and shape applles to graphic design, too.

  • Most of the GNU Emacs integrated environment is written in the programming language called Emacs Lisp. The code written in this programming language is the software—the sets of instructions—that tell the computer what to do when you give it commands. Emacs is designed so that you can write new code in Emacs Lisp and easily install it as an extension to the editor.

  • An enumeration of a collection of items is a complete, ordered listing of all of the items in that collection. The term is commonly used in mathematics and theoretical computer science to refer to a listing of all of the elements of a set. In statistics the term categorical variable is used rather than enumeration. The precise requirements for an enumeration (for example, whether the set must be finite, or whether the list is allowed to contain repetitions) depend on the branch of mathematics and the context in which one is working....

  • Robotics has achieved its greatest success to date in the world of industrial manufacturing. Robot arms, or manipulators, comprise a 2 billion dollar industry. Bolted at its shoulder to a specific position in the assembly line, the robot arm can move with great speed and accuracy to perform repetitive tasks such as spot welding and painting (figure 1.1). In the electronics industry, manipulators place surface-mounted components with superhuman precision, making the portable telephone and laptop computer possible....

  • Now that you’re almost to the end of this guide, let’s look at some ways to continue learning about Unix. Documentation is an obvious choice, but it isn’t always in obvious places. You can save time by taking advantage of other shell features — aliases, functions, and scripts—that let you shorten a repetitive job and “let the computer do the dirty work.”

  • Spreadsheet computer programs or spreadsheets are versatile, powerful tools for doing repetitive or complicated algebraic calculations. They are used in diverse technological fields including manufacturing, design, and finance. Spreadsheets blend the power of high level computer languages with the simplicity of hand calculators. They are ideal for doing "what-if" calculations such as changing a problem’s parameters and comparing the new result to the initial answer.

  • You have probably used a computer for work or fun. Many people use computers for everyday tasks such as balancing a checkbook or writing a term paper. Computers are good for such tasks. They can handle repetitive chores, such as totaling up numbers or placing words on a page, without getting bored or exhausted. Computers also make good game machines because they can play sequences of sounds and pictures, involving the human user in the process. The flexibility of a computer is quite an amazing phenomenon.
