In the paper we present a non-linear parameter estimation method to determine the parameters of a full-car suspension system. Since there are non-measured variables that are necessary for the identification, special numerical techniques need to be applied, such as a numerical integration of the measured signals. It is also shown that the selection of the sampling time might be critical in this type of application. Based on the results of this identification procedure the road disturbance can be reconstructed. The road roughness estimation is based on this signal using autoregressive model.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131668543","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 main goal of a FL coprocessor is to speed up the operations typical for FL algorithms. Current implementations of FL algorithms are dedicated and general purpose. The main drawback of solutions based on dedicated hardware is lack of configurability. Software implementation on general purpose processors is slow for many applications. The basic components of the FL coprocessor presented in this paper are designed in Handel-C using Celoxica's DK Design Suite. The inference engine inside the FL coprocessor is a Mamdani-type engine and the FL coprocessor only supports trapezoid and triangular membership functions. With the DK Design Suite, area estimations are analyzed and throughput is increased by applying pipelining and parallelism transformations.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128370793","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}

However, in most feature extraction methods, covariance matrices must be estimated. When training samples are limited, this estimation is inherently biased, thereby generating ineffective features. In this paper, we propose a new feature extraction method for high dimensional hyperspectral data when limited training samples are available. In the proposed method, we construct a feature matrix using available training samples. The proposed method calculates the difference vector feature matrix using weighted difference vectors among the training samples. Experimental results show that the proposed method improves classification accuracy even if the size of training sample is very small.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129607158","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}

It is supposed that the first vehicle plays leading role while the other members have local controllers trained for keeping a safe tracking distance between themselves and the preceding one. In the model investigated the connection between the vehicles acts like an elastic spring without \"reaction forces\", i.e the (n + 1)th member's motion is influenced by that of the nth member but the members do not affect the motion of the preceding ones. It is supposed that the leading vehicle can freely move, and the aim is to guarantee smooth motion for the last cart of the platoon that may be followed by a participant of the road communication whose driving comfort has to be kept in mind. The carts are modeled as rigid bodies while their loads are represented by masses connected to their carts by elastic springs of dynamic friction. It is shown that the simple semi-mechanistic connection between the carts can result in instable motion due to the resonance in the interaction between the loads and the carts. This effect can be eliminated if the acceleration of the preceding cart is also taken into account in the motion of the actual one. Furthermore, if an adaptive controller of lucid geometric interpretation akin to Soft Computing Solutions is also applied the last cart can trace the nominal trajectory with very good precision.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"171 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120917881","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 procedure induces a logic (as a set of true formulas). In the present paper we analyze the semantic of this logic. By representing the logic of interest through commutative lattices we show that it is a complete and sound logic, which does not have a finite independent axiomatization.
