In [2,3] we describe and prove the convergence of a Jacobi-type procedure for the t r iangular izat ion of an arb i t rary matrix. The t r iangular izat ion procedure requires that in order to t r iangular ize a matrix of order n, i ts two principal submatrices of order (nl ) have to be tr iangularized f i r s t . After the two submatrices have been tr iangular ized, a rotation V( l ,n) is applied i f the element anl of the result ing matrix is s t i l l non-zero. The rotat ion V( l ,n) w i l l make some of the below diagonal elements of the two principal submatrices nonzero, and hence they have to be tr iangular ized again. Theoret ical ly, i t takes an i n f i n i t e series of plane rotat ions to t r iangular ize a matrix of order 3 [3] , and hence i t needs an i n f i n i t e sequence of i n f i n i t e series of plane rotat ions to t r iangular ize a matrix of order n for n > 3. Also switching back and forth among submatrices of lower order is timeconsuming i f the procedure is implemented on computers. Here we s l i gh t l y modify this procedure so that i t can be best implemented on computers, and then, we describe the modified procedure and i ts computer implementation, along with some numerical results. We also give an exp l i c i t expression for the reduction subdiagonal norm ( ~ laajl 2) for an arb i t rary in a>j matrix under one single transformation of A' = V*(k,m)AV(k,m), and an explanation is drawn from this expression as to why the t r iangular izat ion process is handicapped as the subdiagonal norm becomes su f f i c ien t l y small compared to the superdiagonal norm (o~jia j 1 2 ) . _ We shall only describe the procedure for a matrix of order 3, since i t is very t r i v i a l to generalize i t to a matrix of order n > 3.

Each of these cycles has been implemented under considerable time pressure, and consequently, neither a careful theoretical definition nor a needs assessment have ever been made.The author contents that a post-hoc evaluation of the fit of the existing system into a theoretically \"ideal\" model may be performed. The criteria for such a fit, including the comparative costs, are being developed. It is expected that the step-by-step procedure for the analysis should prove useful in other settings, and it may help avoid costly system revisions which may not be necessary.This analysis is proposed by:1. Defining the educational goals of instruction for the academically disadvantaged students who utilize the Center;2. Determining the needs of administrators, instructors, and students in the special admissions program;3. Theoretically developing a computer-managed instructional system and a computer-assisted testing system to support the determined needs;4. Comparing the \"ideal\" system with the existing system in terms of needs met and cost; and5. Recommending a continuation, modification, or replacement of the existing system.","PeriodicalId":166583,"journal":{"name":"Proceedings of the 16th annual Southeast regional conference","volume":"32 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116654226","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}

One increasingly popular solution to this problem is creation of an on-line student registration system and its accompanying data base. Under such a system, student registration may be spaced over an entire semester or, with the availability of more display terminals, conducted over a time span of several days.This paper describes the development of such a system as a class project in advanced information processing. The purpose of this project was threefold:1. To acquire a working knowledge of a data base management system (in this project, DMS II00).2. To gain experience in the use of structured programming, modular programming and team operation techniques.3. To actually implement an on-line registration system using existing equipment at Mississippi State University and demonstrate its effectiveness to the school registrar and other interested parties.","PeriodicalId":166583,"journal":{"name":"Proceedings of the 16th annual Southeast regional conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127714023","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}

GRASP: an interactive system for graphic specification of software GRASP:一个用于软件图形说明的交互式系统

The system is perhaps unique in that programs are graphically displayed in the form of D-charts as the user enters text from a terminal. The philosophy motivating the design of GRASP is summarized by the following principles: (1) to improve programmer effectiveness, \"high-level languages\" must give way to \"high-level systems\" for software development; (2) to avoid obsolete or inaccurate documentation, changes to \"source code\" should be automatically generated as the result of changes made to a program's description; (3) to insure greater understanding of a program's fuction and behavior, the principles underlying structured programming should be applied in its design and organization; (4) documentation of a program should not be static if the program itself is not static; therefore, the program should be viewed as a \"data-base\" from which the programmer can extract information immediately relevant to his concern and comprehension of the program.GRASP will ultimately support a command language which will: (1) describe software modules in terms of single-entry/single-exit control structures; (2) edit data and program files; (3) interactively execute programs or program modules; (4) obtain information about programs; and (5) translate programs into conventional high-level languages.At the present time, we have succeeded in implementing the part of GRASP that provides for the description and display of program modules as single-entry/single exit control structures. The system is being developed on an IBM 370/165 and is currently accessable via a Tektronics terminal.","PeriodicalId":166583,"journal":{"name":"Proceedings of the 16th annual Southeast regional conference","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124412622","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}
