Chairman, Department 1iCVmittee on Graduate Students J1UN 28 1973 ) " I n an e An Evaluation of Text Processing Systems David Urbani Submitted to the Alfred P.Sloan School of Management on May 11, 1973 in partial fulfillment of the requirements for the degree of Master of Science. ABSTRACT Until recently, computers have been used almost exclusively for data processing functions. The payoffs for automating accounting procedures and scientific calculational procedures was large enough to justify the relatively expensive early computer systems. However, as economies of scale and new technology lower the effective cost of computer systems, new and more imaginative applications are being developed. Text processing is one of these applications, and it is to this subject that this thesis is directed. Text processing is the application of computer technology to the production of textual information. There is a wide range of systems and capabilities available today which can be divided into three groups: automatic typewriters, mini-computer supported terminals, and multi-purpose computer supported terminals. Several systems of each type were evaluated and compared. Also, several common, and some not so common, uses of text processing were explored. Since each system has its own advantages and disadvantages, the matching of application requirements to system capabilities is the best method of system selection.

  • A Study of Six University-Based Information Systems 6
    NBS TECHNICAL NOTE 781 A Study of Six University-Based Information Systems NATIONAL BUREAU OF STANDARDS 1 The National Bureau of Standards was established by an act of Congress March 3, 1901. The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, and the Office for Information Programs. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consistent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. The Institute consists of a Center for Radiation Research, an Office of Meas- urement Services and the following divisions: Applied Mathematics — Electricity — Mechanics — Heat — Optical Physics — Nuclear 2 2 3 Sciences — Applied Radiation — Quantum Electronics * — Electromagnetics — Time 3 3 3 and Frequency — Laboratory Astrophysics — Cryogenics . THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measurement, standards, and data on the properties of well-characterized materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; and develops, produces, and distributes standard reference materials.

    Network Working Group 25 January 1971 Request for Comments: 90 R. T. Braden NIC 5707 CCN AS A NETWORK SERVICE CENTER A. INTRODUCTION CCN, the Campus Computing network of UCLA, will shortly be connected to the ARPA Network as a host of the "Service Center" type. The purpose of this RFC is to describe the hardware and software available at CCN and the services we are now planning to provide to other Network Hosts. These services and their implementation priority were chosen in consultation with a particular site (RAND) which plans to use CCN via the Network. We would welcome requests and comments from other sites. B. CCN HARDWARE CCN operates an IBM 360/91KK, i.e., a Model 91 CPU with a 4 million byte fast memory. CPU Speed: Highly program-dependent; 2-6 Mips, with 3 Mips as a useful average. The upper end of this range occurs heavy floating point in the inner loops. The decimal arithmetic operation of a 360 should be avoided as they are executed interpretively by the 91. Memory Speed: Memory is interleaved 16 ways and extensively buffered. Effective memory fetch time is 600 ns in lower 2 million bytes, 900 ns in upper 2 million bytes. I/O Con- figuration a) 6 2860 Selector Channels b) 1 2870 Multiplexor Channcl (with 16 control unit RPQ) c) 5 2314 Disk Storage Units (i.e., 40 disk drives). d) 1 2301 Drum (Systems residence and catalog only.) e) 5 (245x) 9 track tape drives (80O bpi) f) 3 (240x) 7 tracts tape drives (200/556/800 bpi) g) 1 2291 (Modified 2250 CRT) Operator/ Maintenance Console.

  • Chad Is Our Most Important Product
    CHAD IS OUR MOST IMPORTANT PRODUCT An Engineer’s Memoir of Teletype Corporation Jim Haynes The author operating W5YM in 1957 1 I. How it all started When I was growing up in a small town I thought it was an awfully boring place. Now I realize that I had some opportunities that probably would not have been available in a larger city. For one thing, it was possible for a kid to hang out at the newspaper office, telephone office, telegraph office, or radio station and watch a Teletype machine in operation. Things were slow enough that the people who worked there usually had time to answer questions. When I wanted to understand how a Teletype machine worked the wire chief at the telephone office let me borrow the “green book”1. After reading all about selector cams and swords and code bars and pull bars I could drop in to the Western Union office where the manager, a friend of the family, let me play with a little-used printer and see in action all the parts I had read about. Another advantage to living out in the sticks was that television arrived very late. This allowed a pretty good news stand to remain in full operation through most of my teen years. Jack’s News Stand carried several magazines of interest: Radio-Electronics, Radio & Television News, and the amateur radio magazines QST and CQ. Hugo Gernsback’s Radio-Electronics ran a series of articles by Ed- mund C. Berkeley about digital computers, which gave me an early introduction to binary arithmetic, Boolean algebra, and logic circuits.

  • Programming Language) 1 APL (Programming Language)
    APL (programming language) 1 APL (programming language) APL Paradigm array, functional, structured, modular Appeared in 1964 Designed by Kenneth E. Iverson Developer Kenneth E. Iverson Typing discipline dynamic Major implementations IBM APL2, Dyalog APL, APL2000, Sharp APL, APLX Dialects A+, Dyalog APL, APLNext Influenced by mathematical notation [1] [2] [3] [4] Influenced J, K, Mathematica, MATLAB, Nial, PPL, Q APL (named after the book A Programming Language)[5] is an interactive array-oriented language and integrated development environment which is available from a number of commercial and non-commercial vendors[6] and for most computer platforms.[7] It is based on a mathematical notation developed by Kenneth E. Iverson. APL has a combination of unique and relatively uncommon features that appeal to programmers and make it a productive programming language:[8] • It is concise, using symbols rather than words and applying functions to entire arrays without using explicit loops. • It is solution focused, emphasizing the expression of algorithms independently of machine architecture or operating system. • It has just one simple, consistent, and recursive precedence rule: the right argument of a function is the result of the entire expression to its right. • It facilitates problem solving at a high level of abstraction. APL is used in scientific,[9] actuarial,[8] statistical,[10] and financial applications where it is used by practitioners for their own work and by programmers to develop commercial applications. It was an important influence on the development of spreadsheets, functional programming,[11] and computer math packages.[3] It has also inspired several other programming languages.[1] [2] [4] It is also associated with rapid and lightweight development projects in volatile business environments.[12] History The first incarnation of what was later to be the APL programming language was published and formalized in A Programming Language,[5] a book describing a notation invented in 1957 by Kenneth E.
