Implementing Multiple-Linked Lists in the Minicomputer-Microcomputer String Processor, C. StringFirestone, John H. 01 January 1976 (has links) (PDF)
The report will demonstrate how to implement a basic linked-list data structure in RAM for C. STRING. The result of this implementation is Memory Allocation or Data Management which obtains or releases memory space as required in C. STRING. The basic concepts of data structures such as strings, lists and stacks are discussed and the algorithm for allocation of space is developed. The C. STRING user language TOSCL, and the TOSCL parse algorithm with Data Management is described. Finally, the INTEL's Schottky Bipolar LSI microprocessor is microcoded to implement Data Management.

An interactive information system for tracking student academic progress and aid in course schedulingBehi, Farahzad 01 January 1985 (has links) (PDF)
An interactive information system has been developed for the Computer Engineering Department to promote faster and more accurate means of obtaining academic information on a student or a group of students. It was also developed to provide departmental administrative personnel with information to guide course scheduling. The system has the capability of providing the following information concerning undergraduate students enrolled in the Computer Engineering program of the College of Engineering, University of Central Florida. 1. Basic information about the student, such as, address, telephone number, classification, etc. 2. A student's completed and in-progress courses 3. The grade and other information, such as, equivalent transfer credits or UCD resident credits for each course 4. Name and social security number of all the students working under the same advisor 5. Name and social security number of all the students in the same year of college (classification) 6. Name and social security number of all students that have taken or are taking a certain course 7. Name and number of all students with the same classification taking the same course The system provides the user with the additional capabilities to: 1. Update the information in the student's record by interactive operation 2. Delete a student from the data base 3. Print the sorted name and social security numbers of all the students that have a record in the data base

An associative backend machine for data base managementHurson, Alireza 01 January 1980 (has links) (PDF)
It has long been recognized that computer systems containing large data bases expend an inordinate amount of time managing the resources (viz. central processing time, memory, ... etc.) rather than performing useful computation in response to user I s query. This is due to the adaptation of the classical machine architecture, the so called von Neumann architecture, to a problem domain that needs radically different machine architecture for an efficient solution. The characteristics that distinguish the computation for data base management systems are: massive amount of data, simple repetitive non-numeric operations and the association of a name space with the information space at a high level. The current systems meet these requirements by memory management techniques, specially designed application programs and a sophisticated address mapping methods. This accounts for a large software overhead and the resulting semantic gap between the high level language and the underlying machine architecture. To overcome the difficulties of the von Neumann machines, Slotnick suggested the idea of the hardware backend processing by distributing the processing capabilities outside of CPU and among the read/write cells. These cells act as filters which imp rove the system performance by reducing the processing load on the CPU as well as the amount of data transported back and forth between secondary and main storage. The major contribution of this dissertation is the definition of a backend machine architecture ASLM (Associative Search Language Machine) and the development of a query language ASL (Associative Search Language) which is directly executed by the backend machine using built-in hardware algorithms for query processing and associative hardware for name-space resolution. The language ASL is a high level data base language using associative principles for basic operations. The language has been defined based on the relational data model. ASL is relationally complete, and provides complete data independence. ASL provides facilities for query, insertion, detection and update operations on tuples of variable sizes. Moreover, the structure of the statements in ASL are represented in arithmetic expressions like entities called set expressions. ASLM is designed based on cellular organization, a design similar to Slotnick's idea with an important exception. In the design of ASLM, the processing units (cells) are moved into the backend machine. The general strategy in ASLM is based on the pre-search through the data file and then the execution of the operations on the explicit subfiles which are stored in the associative memory. The generation of the subrelations explicitly eliminates the existence of so-called mark bits in some of the previously designed data base machines. Moreover, it provides fast algorithms for international operations such as join. ASLM is also microprogrammable which gives more flexibility to the system. The design of the ASLM differs from the majority of the data base machines based on Slotnick's idea: first, the separation of the cells from the secondary storage will result in a cost effective system in comparison to the other machines. This also eliminates any restriction on the secondary devices. Second, since cells are independent of each other there is no need for interconnection network between the cells. Third, ASLM is implemented by associative memory, the closeness between associative operations and data base operations reduces the existing semantic gap found in the conventional system, and fourth, ASLM is expandable to the MIMD class of machines.

Creating and Exploring the Educational Potential of a Computerized Pictorial Biology Database / The Educational Potential of a Computerized Biology DatabasePassmore, Graham 08 1900 (has links)
The Bioloqy Department at McMaster University is interested in courses for which students can generate computerized text presentations around a computerized data base of biological images. The student texts are to be added to the pre-existing data base at the end of the semester. This project describes the problems encountered when developing a CD-ROM to contain the images. The images were initially incorporated onto Kodak photo CDs. To place all the images on a single CD-ROM they were compressed into a JPEG file format. The suitability of Asymetrix Multimedia ToolBook 3.0 and Microsoft PowerPoint 4.0 for use by students preparing accompanying text is then assessed.
A development strategy for the data base is then explored. Hypertext is judged to be the environment of choice. Research into the structuring of hypertext to enhance student learning reveals that the development of tutorials to accompany the students' texts and the computerized data base will be a crucial step. Behaviourist and cognitive psychology strategies for learning are used as a platform to suggest a structure for the data base. Finally interface design research is used to outline the format of the student presentations. / Thesis / Master of Science (Teaching)

The Generation and Management of Museum-Centered Geologic Materials and InformationTimm, Sarah Louise 10 April 2012 (has links)
This thesis integrates three disciplines: geosciences, computer science, and museum collections management. Although these are not commonly integrated, by developing their intersection this thesis uniquely contributes a much-needed system for effectively managing geological collections. The lack of effective organization and management of collections can result in a serious problem: not only is history lost, but so is the potential for collection of further data from documented samples using newer analytical techniques. Using the Department of Geosciences at Virginia Tech as a beta testing ground, the electronic geological management system, EGEMS, was developed (Chapter 2). A database such as EGEMS should provide ready access to useful information including, a material's provenance or current location, as well as any published analytical data. Past experiences volunteering in museums have allowed the author to design a system that is easily queried for such information. The organizational scheme and data model integral to the functionality of EGEMS was driven by direct experiences with geological research, in particular the electron microprobe analyses of Mn-rich minerals from the Hutter Mine, Virginia (Chapter 1). The final component of this thesis (Chapter 3) describes a facet of museum science that is most important—communication. This project records the development of a museum exhibit. Titled "The Search for the Mysterious Mineral," this approach relies on pedagogical tools to engage the audience, and to illustrate how the scientific method used by a geologist is the same technique used in any problem solving. The exploration involved in these projects has lead to an enhanced understanding and appreciation for connections among generating, managing, and communicating geological information. / Master of Science
