The need for better image processing techniques has lead to the emergence of many approaches and techniques, which aim to achieve faster, cheaper and more user-friendly operations. Multiscale analysis for edge detection is a powerful approach to image recognition. However, this approach suffers huge computational and time cost which, consequently, jeopardise its efficiency. This paper presents a new technique in image processing that aims to reduce high computational cost, to provide rapid 3-dimensional objects recognition and has a wide domain of applications. The novel Automatic Edge Detection Scheme (AEDS) combines neural network technology with multiscale analysis, to achieve automatic recognition of high and low contrast images that contain two or three-dimensional objects. The AEDS is based on applying scale space analysis using the Laplacian of a Gaussian edge detection operator, together with a neural network model. This technique will be utilised to detect foetal head and abdominal circumferences. Monitoring the development of a baby during gestation using ultrasound scan, provides vital information on the growth of the foetus and can predict any abnormalities such as Down's syndrome. Providing a fast, user-friendly and low-cost system for the automatic detection, prevents the possibility of human errors in obtaining foetal measurements. In addition, the new automatic image recognition technique can be efficiently applied in other fields.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128101083","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 increased applicability is a result of both improved laser technology, and in particular the availability of low cost, high power, semiconductor lasers, and a greater understanding of the way in which laser energy interacts with materials used in soldering. This paper considers the requirements for a typical laser soldering system and the types of laser which may be used, with particular emphasis on the relevant characteristics of semiconductor lasers. It then considers the ways in which laser energy interacts with the different materials used and how heat is transferred within joints. It is shown that an understanding of the heat transfer processes is essential to the successful application of the technique. The range of applicability of laser soldering is illustrated by the description of three industrial laser soldering systems developed by the authors and by consideration of the potential for future applications.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125105432","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}

MMS introduces the concept of a Virtual Manufacturing Device (VMD) providing a common view of all physical devices. Wide spread use of MMS in industrial plants depends heavily on real-time support. This paper presents an approach to the implementation of an MMS server for shop-floor devices that takes into account real-time requirements. Our MMS server has a dynamically reconfigurable software architecture of a Real-Time Control Operating System (RTCOS). It is based on Microware's OS-9 real-time multitasking operating system kernel. In our framework, multiple reconfigurable control sub-systems represent multiple Virtual Manufacturing Devices (VMD). The sub-systems can be developed independently of target driver devices. This paper focus on the software architecture of our Real-time Control Operating system MMS Server called RCOMS and discusses the advantages of our approach compared to other MMS implementations.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121682474","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}
