Integrating graphics into text allows the graphics to be proportioned so that the illustration appears on the same page with the text describing the graphics. When text and graphics appear on the same page, the reader follows the explanation of the graphics; when a reader has to turn to the end of the report to see the graphics, the reader loses the coherence of the report. To integrate graphics and text, information about graphics terminology as well as details about word-processing and graphics programs and printers are needed. The author discusses these topics, as well as preparing slide presentations from graphics.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132909058","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}

More computing power and memory are being squeezed into fewer integrated circuits to provide increasingly more powerful instruments. The PC itself has become a powerful tool in biomedical computing applications. In the future, it will be possible to develop new medical instruments to address problems that were previously not solvable. This possibility exists because microprocessor-based systems continuously increase in computing power and memory and concurrently decrease in size, cost, and power consumption.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116094933","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}

There are two principal methodologies: single photon emission tomography (SPET) and positron emission tomography (PET). Both methods of emission tomography can benefit from a new method of image reconstruction. This method, the maximum likelihood estimator (MLE) method of reconstruction, has the practical advantage that the image noise is smaller in regions of low radioisotope concentration, instead of the rather uniformly distributed noise obtained with conventional filtered backprojection (FBP) reconstruction methods. The author describes the most important mathematical ideas underlying the MLE method and show some results obtained with it, in comparison with FBP results.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126517804","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}

The first model describes the evolution of a manager from an engineer; the second, the evolution of a technology. The third describes the evolution of a product, the fourth, the evolution of an enterprise or industry. The fifth describes the strategic process. The sixth and final 'model' contains a set of simultaneous constraints that limit management influence.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"69 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116253076","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}
