It is based on the measurement of Electrical Bio-Impedance (EBI) on radial artery. Reconstruction of the CAP curve from the EBI data is provided by an introduced spectral domain transfer function (TF). The TF estimation algorithm and the Augmentation Index (AI) evaluation method are described. Proposed approach is less dependent on the operator and more convenient than traditional tonometry based method. It allows continuous and long term monitoring of the AI and CAP variations. Feasibility and accuracy of the technique was evaluated in clinical surroundings by comparing invasively measured CAP and AI data with non-invasive EBI based estimates. Clinical experiments were conducted in the Heart Centre of the East-Tallinn Central Hospital during scheduled coronary angiography. Age of the patients varied randomly between 43 and 80.","PeriodicalId":348260,"journal":{"name":"2014 14th Biennial Baltic Electronic Conference (BEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128067579","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 based on the method of redefining products suggested before. It is known that a behavior of a subcircuit of a combinational circuit is presented by the incompletely specified Boolean function. It means that there are the input Boolean vectors of a circuit on which the value of the subcircuit output has no effect on the value of the circuit output. It is set up that the on-set vectors of a subcircuit incompletely specified Boolean function are represented by all test patterns for the stuck-at 0 fault at a subcircuit output and the off-set vectors are represented by all test patterns for the stuck-at 1 fault at the same output. This result may be used for structural combinational circuit minimizing and for partially programmable circuit design.

Our new method exploits optical beams produced by an Optical Built-In Logic-Block Observation (OBILBO) register based on the captured data presented on the outputs of all stages of the registers in the BILBO. Then it is possible to send the captured data to remote system equipped with optical sensors in real time way. The final captured response data can also be used for final comparison with stored data of a golden circuit. Preliminary simulation results showed that faults are concurrently detected without affecting normal system operation and without having recourse to any external or internal Automatic Test Pattern Generation (ATPG).","PeriodicalId":348260,"journal":{"name":"2014 14th Biennial Baltic Electronic Conference (BEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121856720","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}

First, we briefly introduce the motivation for handling permanent and transient faults within a combined architecture. Then, based on the well known TMR scheme, we present the difference in modeling the reliability for permanent and transient faults. Subsequently, we introduce two distinct methods for modeling both fault types together and explain how the calculation of the reliability can be done. Both models vary in their accuracy and complexity. Furthermore, we apply the proposed modeling strategies to a more complex system, where permanent fault compensation is used to keep transient fault detection/masking unaffected. Modeling this system with both methods is discussed for varying system parameters and failure rates. The results show that in particular situations the use of the simple model is sufficient and makes system modeling less time consuming. But in some cases the inaccuracy of the simplified model will cause an excessively optimistic estimation of the reliability.","PeriodicalId":348260,"journal":{"name":"2014 14th Biennial Baltic Electronic Conference (BEC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114490816","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 method allows cell balancing in both battery operating modes, recharging and driving modes. To verify the applicability of the method, computer simulation was conducted analysing how the system balances during a driving period, by following a real current profile measured from a real REVAi driving. The obtained results show how at the end of the driving period the system is already balanced, allowing a subsequent high speed charge and avoiding a later equalisation stage. Finally, the integration of the balancing system into a higher level system, based on a multiport converter topology is discussed.","PeriodicalId":348260,"journal":{"name":"2014 14th Biennial Baltic Electronic Conference (BEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130142111","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}
