The onset of micro-sleeps can be detected by decreasing activity of alpha brain waves and increasing activity of delta brain waves. To develop an automated system for micro-sleeps detection an analysis tool for EEG recordings has been developed. The system has been tested in several experiments of drivers in a car simulator. The developed prototype, experiments and experimental results will be reported in this paper.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121924611","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}

These images often suffer from low quality, intensity inhomogeneity and artefacts. Due to this, edges of segmented objects may be corrupted. Conventional methods for image processing are therefore insufficient. The newly developed method suited for automatic circular object detection and segmentation is capable to keep the original arterial borders, while precisely segmenting the eventual pathology. Hough transform was used for artery detection. Active contour based on level set methods was adjusted according to our needs and applied for the object segmentation.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126912630","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}

Due to the relatively large operating cost of fine-grained parallelism, the systems are often task-oriented. With the recent appearance of more synchronous platforms for parallel computing, we propose a language supported task system optimization for strictly synchronous multi-core architectures equipped with hardware accelerated multi-prefix operations and other finite resources (with respect to concurrent access). The purpose of this system is to dynamically manage the error prone allocation of such resources, yet provide reasonable performance speedups without placing the burden of resource management to the programmer. Our system compiles several specialized versions of accelerated functions that are dynamically picked by the runtime task system based on the tasks' requirements and the resource availability.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126508237","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}

There are already various technologies that can be used to gather data and more or less precisely estimate the user's location. In our work, we use Bluetooth Low Energy beacons. When these transmitters are properly placed in the environment, their signal can serve as a data input. We designed a feed-forward artificial neural network that processes this data and produces estimated coordinates that denote the position of the user. Experiments show, that our approach achieves the best average precision of 1.21 meters which is comparable to results reported by other known approaches.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130245353","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 makes it more difficult to analyse data related to returning visitors, such as number of sessions per user, time from last session, etc. We propose a method for deduplication of records from the same user based on mix of device factors and mouse usage biometrics. Another issue of website visits data comes from multiple users using a shared computer. We tackle this problem with a method that splits records based on mouse movement features in order to distinguish visitors. The paper provides preliminary results for both methods that show promising improvements in making the visitors statistics more precise.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114226284","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 our earlier work, a definition of \"exact HT\" has been introduced for both given grids (XsizexYsize) and (PsizexΘsize) of the input image and of the HT result, respectively, considering the (ρ,θ)-HT like a Radon transform (RT). A few iterative approaches have been also proposed there to approximate the exact HT for reducing the performance complexity to not much bigger one than cubic. However, these approaches become less acceptable with increasing of the input image grid as in the case of astronomical images, e.g. when HT is applied for identification of flare stars in archive images of stellar chains. In this work an analytic solution is proposed for distribution of the exact (ρ,θ)-HT model into the chosen HT-grid of the output. Notwithstanding that its complexity remains traditionally cubic, i.e. ~XsizeYsizeΘsize, the proposed exact HT can perform faster than many recent approaches to HT or RT, based on Fractional Fast Fourier Transform and been of square complexity, if high enough requirements for preciseness are required.","PeriodicalId":291570,"journal":{"name":"Proceedings of the 17th International Conference on Computer Systems and Technologies 2016","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127555511","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 system was continuously used in an exhibition at the Visconti Castle of Pavia (Italy) from 14th June to 29th November 2015.

The main purpose of the system is to facilitate the classification of the unknown food products to the set of predefined classes related to different client groups. In our case these classes are food products appropriate/not appropriate for children, adults below 60 years with high physical activity, low physical activity, adults above 60, etc but the system is not limited to these classes and can be used with any other classification hierarchy. The base metric that the system uses to compare food products was thoroughly presented in our previous publication [5].
