Introduction Mathematical modelling has become recognized as an important component in applied mathematics curricula during the past ten years. Evidence of this fact is the existence of several textbooks in modelling published in recent years. The need for such a course stems from the neglect of modelling concepts in most undergraduate courses in which time constraints usually do not allow the inclusion of modelling with the theory and techniques. At Florida State University, the course Mathematical Modelling of Scientif ic Problems, a junior level course (with prerequisites of calculus, including some ordinary d i f f erential equations), has been introduced to f i l l this void. The computer can play a v i ta l role in a modelling course without downgrading the role of qualitative analysis. As a calculation and graphing device the computer can free time for concentration on modelling concepts such as formulation, result analyses and modification. The results of computer runs often suggest the form of an analysis that can generalize and render understandable the specific results of a few \"model runs;\" see Greenspan (1971). The computer can indicate the degree to which approximations made in an analysis are in fact realized. The computer could indicate that a part icular model is absurd and this save the modeller the effort of considering the model at a l l . As part of the CAUSE project at FSU, a package of mathematical modelling modules have been developed during the past 3 years. They consist of FORTRAN programs which produce digital and graphical output with l i t t l e computer experience required by the user. The modules play a variety of roles in the course. The instructor can use them to generate examples of material discussed in class. The students can use them to answer their own questions such as \"What would happen i f our","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"276 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":"128342892","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}

In a computer automated spectrometer, in addition to the several advantages, one is able to use new techniques in digital data manipulation to improve the quality of the spectral data. In this paper, the interfacing of an Hewlett-Packard Model 8460A microwave spectrometer with an Intel 8085 MPU based microcomputer is discussed. The two important objectives of this work were to enable a relatively inexperienced operator to obtain the data by running the experiment and to take advantage of the power of digital techniques available. The microcomputer has 64K bytes of dynamic random access memory. Among the other accessories are a dual floppy disk drive, a decwriter and a video monitor. The data acquisition is accomplished using AltairT'M'8800 Analog to Digital/ Digital to Analog (AD/DA) converter. The hardware interface with the microwave spectrometer system is done through a programmable I/0 board, using two Intel 8255 I/O chips. The components of a microwave spectrometer and its operation will be discussed briefly. Of the various components, the Sweep Control unit is of particular importance. This unit accepts the frequency command from the computer in BCD code and processes it to select a specific frequency. The corresponding analog output from the spectrometer is digitized and stored in a floppy diskette. To display this spectral data, the microcomputer is also interfaced with an X-Y plotter. The algorithm used in developing the software for the data acquisition from the spectrometer is given below. i. START; 2. Set the experimental conditions; 3. Initialize the I/O ports for output; 4.
