Multilingual simulation places additional, rigorous requirements on all three integral parts of the simulation universe: tools, model development and design. This paper discusses compatibility criteria for models developed in a particular language and used in a multilingual environment. It investigates major causes of model vs. model or model vs. simulator incompatibilities and presents the necessary conditions for model compatibility.

A new sum-of-sinusoids (SOS) model for modeling fading channel is proposed. Unlike most of RLS analyses, our analysis takes the correlation of the inverse of correlation matrix into account and hence yields an improved recursive formula for the MSE, which can be computed recursively with the information of the second order statistics of fading channels. The steady state MSE of RLS is derived for Clarke's model.

The vision system consists of two types of analog chips: a silicon retina and a simple cell chip. The center-surround concentric receptive fields of the silicon retina are aggregated in the simple cell chip, mimicking the hierarchical architecture in the visual system of the brain. Both chips have 100 times 100 pixels. Using the orientation-selective outputs obtained from the multi-chip system, texture segregation was conducted based on a computational model inspired by neurophysiology. The texture image was filtered by the two orthogonally oriented receptive fields of the multi-chip system and the filtered images were combined to segregate the area of different texture orientation with the aid of field programmable gate array (FPGA). The present multi-chip system is useful to emulate and verify computational models for texture segregation of the cortical cells","PeriodicalId":423693,"journal":{"name":"2006 IEEE International Symposium on Circuits and Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116895347","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 particular, our delay-dependent exponential stability conditions give explicitly the allowable upper bound of the delays that guarantees stability of Cohen-Grossberg neural networks, and are applicable to the case when the non-delayed terms cannot dominate the delayed terms.

In this paper a novel fast global motion estimation algorithm based on iterative least square estimation (ILSE) is proposed for a four-parameter linear global motion model. The basic idea is to design rules to keep the symmetrical structure of processing units during iterative process, which can enormously reduce the computation load without impact on the estimation accuracy. The performance of the proposed fast-ILSE is analyzed and compared with traditional ILSE algorithm using sum of absolute difference (SAD) as criteria. Roughly about 50% addition operation is eliminated during calculation of zoom parameters, and 100% multiplying operation and 75% of adding operations are eliminated during calculation of pan parameters.
