The authors feel that this system, the Motor Carrier Information System (MCIS), has successfully combined the advantages of several available data processing concepts to produce a very useful regulatory tool.Although the next section does provide a brief overall description of the MClS, this paper deals specifically with only one phase of the system, the handling of ICC Regulated Carriers. It should become clear that the techniques used within the MCIS readily lend themselves to any data processing application where data can be separated into two categories: (1) Identification information (fairly fixed in length) and (2) free format text (unlimited in length, with possible subdivisions).","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125876541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This instructional system is designed to enable individuals with a wide range of abilities to achieve an eighth-grade level of competence in reading, math, and language skills. PLATO, a multimedia computer-based educational delivery system, is the focal point of the Basic Skills curriculum.The major purposes of the field test were to 1) determine the operational feasibility of remote PLATO sites in high schools, 2) field test the mathematics courseware, 3) provide data showing PLATO's effectiveness in remedial mathematics instruction, and 4) provide an economic analysis for using PLATO in public schools.The three test sites represented a cross-section of Florida high school students in need of remedial mathematics. The participating schools were Paxon Senior High School (Jacksonville), Sarasota Senior High School (Sarasota), and Glades Central High School (Belle Glade), representing an urban, a suburban, and a rural population. Each site was equipped with eight PLATO terminals in one classroom, which were connected to a central computer at Florida State University via a single telephone line.","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126079607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Miles","doi":"10.1145/503838.503867","DOIUrl":"https://doi.org/10.1145/503838.503867","url":null,"abstract":"Computer generation of color patterns, has revived interest in various classical models for color distribution (triangular, circular, pyramidal, conical, spherical etc.). The oldest model is the color spectrum displayed in the heavens by the rainbow: heme frequencies of the refracted visible light determine the color variations. Newton, by observing sunlight passing through a prism developed a down to earth model to demonstrate colors obtained by separating white light into its components. The properties of colors generated by combining primary colored lights (the additive system with primary components, red, green, and blue) were discovered to be different from those in the subtractive system of pigments where reflected light has colors filtered out by pigment combinations used. Here, the primary colors ape cyan, magenta and yellow, respectively. The author will display dual models generated on the Intecolor 8051 for these two systems. I In the additive model, 000 is assigned to black, the console color when no light is present and ill is assigned to white, where the three primaries are supplied in equal strength. In the subtractive system, 000 is assigned to white for the fully reflective surface and Ill, to black which is obtained by filtering with all three pigments covering the white base. The table below shows the duality between the systems.

In the additive system, the binary numbers show which of the blue, green or red light guns are turned on to produce the desired light status on a black cathode ray tube screen. In the subtractive system, the three digits from left to right tell you which additive primary colors are filtered out in the pigments combined to produce color reflections when applied to a white reflecting canvas.

{"title":"General image manipulation functions in a geographic information system","authors":"D. Scott","doi":"10.1145/503838.503856","DOIUrl":"https://doi.org/10.1145/503838.503856","url":null,"abstract":"Historically, potential computer users with wide ranges of applications have found the computer very complex and difficult to use. In addition, their prohibitive costs have driven away many people who could have used them. Newer computers are even more complex, but they tend to be easier and cheaper to use. As such, their range of applicability has increased dramatically. Where the first computer was used to solve very demanding and time-comsuming scientific ballistic applications, today's computers are used in scientific applications, in business applications, and even in automobiles and washing machines. The large number of areas in which computers are being introduced is partly due to the availability of computers which can do the application. However, in some instances, it is the nature of the application that creates the demand for a computer to do the job. For instance, some jobs, such as very large payroll or inventory systems, are very cumbersome and error prone if done manually. The amount of data is simply too much for a human staff. One specific example of an application where computers are becomming necessary is in the area of geographic information processing. Computerized geographic information processing is a logical development in the use of location-specific data. Location specific data is information that is concerned with, or can be distributed over, land areas. Examples of this are land ownership, use, and population. All of these examples of location specific data have traditionally been done by hand. The involvement of computers into these areas was caused by the bulk of data and its need to be easily and quickly retrieved. Moreover, the data for land ownership, which may come from county records, the population data, which may come from the census bureau, and other data such as land use and cover must be frequently merged and manipulated together in a manner which would be very impractical if done manually. This is now beginning to change with the advent of computerized geographic information processing. Several local, state, and federal agencies are now developing, or have recently developed, systems for their own use. The data for the systems has come from both ground-truth and aerial photographs as well as from existing information. Since the launch of the Landsat satellite series, new information is becoming available at a staggering rate. For example, a scene of Landsat data covers an area of about 185 by 185 kilometers square.
