The standard UNI EN ISO 7730:2006 classifies the conditions of moderate confined environments by three categories according to the PMV index. The comfort sensation is mainly affected by four variables: air temperature, mean radiant temperature, air velocity, relative humidity. They are all mechanical and thermal quantities therefore they are measured through the same measurement method. In evaluating the PMV index two more variables are taken into account: metabolism and clothing insulation. They can be evaluated by different accuracy levels. Their indirect measure is subjected to more uncertainty than the above four measuring parameters and the distribution is typically non-Gaussian. The paper analyses the uncertainty in PMV measuring through the Monte Carlo simulation. The proposed study identifies the different weight of independent variables showing as their uncertainty, particularly those referred to metabolism and clothing insulation, affects considerably the final values for classifying the moderate environments.","PeriodicalId":205930,"journal":{"name":"2014 23rd International Conference on Robotics in Alpe-Adria-Danube Region (RAAD)","volume":"460 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114498175","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 performance of object recognition largely depends on the training dataset. Usually such training sets are gathered manually by a human operator, a tedious procedure, which ultimately limits the size of the dataset. One reason for manual selection of samples is that results returned by search engines often contain irrelevant images, mainly due to the problem of homographs (words spelled the same but with different meanings). In this paper we present an automated and unsupervised method, coined Trainingset Cleaning by Translation (TCT), for generation of training sets which are able to deal with the problem of homographs. For disambiguation, it uses the context provided by a command like “tighten the nut” together with a combination of public image searches, text searches and translation services. We compare our approach against plain Google image search qualitatively as well as in a classification task and demonstrate that our method indeed leads to a task-relevant training set, which results in an improvement of 24.1% in object recognition for 12 ambiguous classes. In addition, we present an application of our method to a real robot scenario.","PeriodicalId":205930,"journal":{"name":"2014 23rd International Conference on Robotics in Alpe-Adria-Danube Region (RAAD)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115957047","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 want to emphasize that by the vibrodiagnostics method, which is one of the methods for ensuring the operability of the robot, extended life of the industrial robots and energy savings will be reached. The vibration measurements had been realized using the three accelerometers. Their evaluation was done via computer software ScopeWin. FFT transformation was applied for analysis of the spectrum of vibration. The purpose of the paper lies in proposing a comprehensive methodology for the measurement and evaluation of vibration on the industrial robot, and serves as a way to obtain additional recommendations and drafts of the procedures for maintenance and fault diagnosis of the industrial robots.","PeriodicalId":205930,"journal":{"name":"2014 23rd International Conference on Robotics in Alpe-Adria-Danube Region (RAAD)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114931143","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}
