A modified carry save array is used in conjunction with Booth's algorithm to reduce the partial product addition and interconnection. A special rounding technique called Trailing-1's Predictor is used to speed up the final addition and rounding. This chip uses a new layout methodology for easy design structure and improved GaAs technology layout density. The combination of the fast arithmetic architecture and compact layout style achieves 4ns multiplication time with 3.5 W power dissipation at 75/spl deg/C. The area is 2.43 mm by 3.77 mm (excluding pads) and uses 28000 transistors to give a density of 3056 transistors/mm/sup 2/ for 0.8/spl mu/m GaAs technology.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124414187","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}

We have discussed an additive fuzzy clustering model previously. The merits of the additive fuzzy clustering models are (1) the amount of computations for the identification of the models are much fewer than in a hard clustering model and (2) we obtain a suitable fitness by using fewer number of clusters. This paper proposes a general class of the clustering model, in which aggregation operators are used to define the degree of simultaneous belongingness of a pair of objects to a cluster. We discuss some required conditions for the aggregation operators. T-norms are concrete examples for satisfying these conditions. Moreover, the validity of this model is shown by investigating a characteristic of the model and numerical applications.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115597657","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 three specific techniques from the field of artificial intelligence used to produce the adaptive process control systems are: (1) fuzzy logic, (2) genetic algorithms, and (3) neural networks. Fuzzy logic is a technique in which the human \"rule-of-thumb\" approach to decision making is modelled. Genetic algorithms are search algorithms based on the mechanics of natural genetics that are able to rapidly locate near-optimum solutions to difficult problems. Neural networks are crude paradigms of the mammalian brain that have been used to model industrial systems. This paper provides an overview of the architecture used to achieve adaptive process control, and demonstrates its effectiveness in the control of an industrial motivated titration system.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115978828","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}

For this purpose, histograms of texture element's properties are used. Compactness property of an element has been used for characterisation. The compactness depends upon its perimeter. A novel method based on perimeter contribution, to compute the value of perimeter is presented. The perimeter value computed using the proposed method is closer to the actual, than the perimeter value computed using the conventional methods. The value of perimeter using proposed method is also more consistent than the conventional methods. The value of compactness using the proposed method are not only closer to actual value but also more consistent under affine transformations. Invariant histogram of compactness using the invariant value of compactness characterises texture invariant of scaling and rotation.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133566787","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}

If the rotational motion is known, the data can be corrected by resampling from the polar grid on which the data is collected, to a rectangular grid. A focused ISAR image can be then formed by using a 2D FFT. In practice the rotational motion is not known a priori and so it must be estimated from the data itself. This paper presents a technique for estimating the target's rotational motion. The rotational motion is modelled as a quadratic, the parameters of which are set by minimising the entropy of a single cross range profile of the data. The minimum entropy cross range profile is the best focused cross range profile which should result in a focused ISAR image. Alternatively the entropy of the image itself could be minimised, but this has not been considered as it is computationally intensive.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130736671","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}
