It is well known that computers which control systems are greatly affected by delays and jitter occurring in the control loop. In the literature, a deadline reduction approach has been considered as one solution to reducing the jitter experienced by a task and therefore obtaining better loop stability in the control loop. Here, in order to improve the sensitivity of the deadlines, we propose another solution for reducing the deadline of a task when all tasks are scheduled with the Deadline Monotonic Algorithm. This is performed for a specific asynchronous scenario for harmonic periodic tasks. We compare the results to those for the synchronous scenario.","PeriodicalId":270103,"journal":{"name":"2009 Fourth International Conference on Systems","volume":"2 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127716669","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 this paper is to compare different methods to combine the results of both classifiers – both paralanguage and facial expressions. A prototype of the dialog system was developed in the Department of Computer Science . The proposed system is fully automatic, user-independent and real-time working. Several experiments show that the speech recognition quality is increased by using nonverbal information.

Leaving Aristotelian logic aside and introducing an aporetic view in this “primary paradigm of reality perception” lead to a whole new set of problem-solving methodologies.This paper is a short version of one part in a series dealing with System Thinking and Acting and the connections with and differences to the application of daoistic thinking models.","PeriodicalId":270103,"journal":{"name":"2009 Fourth International Conference on Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116894683","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}
