Our research is geared towards applying techniques at the cross roads between econometrics, statistics and graph theory in order to improve the tools for analyzing the key factors that influence the state of the economy as seen through the gross domestic product. The novelty of our approach is characterized by decomposition of the key sectors of the GDP and building a spatial representation of the relationships between them in the form of a complex graph.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126393803","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 paper applies the Relaxed TP model transformation based Control Design Framework that supports both the complexity-accuracy trade-off of the TP model representation and convex hull manipulation separately executable on all components of the control system to be derived. Some specialization and further relaxation of the framework is also proposed here for frequent cases when all components of the system is handled in TP model form. The framework is also extended with a TP model interpolation technique to perform a systematic convex hull manipulation. The overall investigation is done on the complex NATA model of the three degree of freedom aeroelastic wing section model including Stribeck friction. The paper concludes and via the example proofs that both the complexity and the convex hull strongly influences the feasibility of the design. Further the paper proofs that the separate convex hull manipulation of the given model done for controller and the observer design also has to be taken into consideration.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127927736","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}

Singularities arise when solving inverse positioning and inverse orientation as well.

The transformed problem is regularized in singular configurations, thus the inverse orientation problem becomes well-conditioned in every configuration. The methodology is illustrated on an Euler wrist.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125910848","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}

For this purpose, the C language is used very often. The further steps of the synthesis procedure are based on some kind of data flow graph representation of the task. Therefore, transforming C-code into a graph representation (as systematic as possible) is crucial step in the whole synthesis procedure. One of the difficulty in formalizing transformation algorithm is that the C-code may contain nested loops. The existing solutions suffer from the difficulty of handling such loop nest hierarchy. We present a method, which can solve systematically the transformation from the C-code into a multi-rate data flow graph representation by handling the nested loops. The main steps of the method are illustrated by a simple example.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122180950","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 work is using open source frameworks and libraries such as WebRTC (Web Real-Time Communication), JSARToolKit (JavaScript Augmented Reality Toolkit), Three.js and NanoDICOM. The system builds a 3D model from the slices of a patient's DICOM imagistic investigation files, superimposes the model on the body area of interest using Augmented Reality and sends the camera images remotely. The main advantage consists in real-time viewing of imagistic patient information by assisting physicians or medical students. Virtually attaching the 3D model to a specific area of the body allows the model to rotate and move in the same time with the patient. The proposed application does not depend on any operating system and runs inside a browser window without any closed source plug-in, allowing it to be accessed on any computer or mobile device that has a suitable browser.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130953937","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}

To achieve the desired goal multi-stage image processing techniques are used. The vascular network and the red regions are highlighted using morphological methods, so these can be segmented with region growing algorithms. Mask is generated that contains only the blood vessels. The red blobs of original images are classified using the generated binary image and their produced skeleton. Our goal is to detect as many as possible microaneurysms taking their shape and size into account. Experiments with manual settings on the test images showed approx. 50% of detection performance, and it can be further improved by development of pre-processing and increasing classification criteria. The developed system can help the manual evaluation of microaneurysms, hence can accelerate of the work of doctors.","PeriodicalId":163447,"journal":{"name":"2014 IEEE 9th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123613157","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}
