The developed system uses a space-varying approach in real-time analysis of 2D nonstationary signals, related to the space/spatial-frequency (S/SF) domain tool based on the 2D cross-terms-free Wigner distribution. The system is based on the correspondence of the filter's region of support (FRS) to the local frequency (LF) of the filtered signal. By implementing the LF estimation, the system performs filtering of nonsationary 2D signals. The estimation has been implemented by the sliding matrix operation, which presents the central part of the developed design. The developed filter permits multiple FRS detection in the observed 2D signal point. In this way it enables a very efficient real-time filtering of nonstationary monocomponent and multicomponent FM signals, highly concentrated in the S/SF space and exposed to the high white noise. The design is proven through the verification of the sliding matrix operation. It is also tested by the simulation on the multicomponent highly nonstationary noisy signal filtering.","PeriodicalId":136720,"journal":{"name":"Eurocon 2013","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132036651","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 human-to-human interaction emotion perception is the perception on the emotion of the other people, which, due to the nature of emotions is not so precise. On the other hand, perception on emotions in human-computer interaction is still an open problem. A lot of work is done in direction of finding suitable model for perceiving emotions based on different input signals and classification models. Here, only sound signals are considered. Still, the percentage of the classification of emotion in natural environment isn't satisfactory. Finding a suitable model for emotion classification based on emotion evaluation is the objective of this paper. We investigated the available methods for finding the most important sound features and introduced a novel approach to finding them. Our approach includes knowledge from psychological studies that analyzed the human perception on emotions. A classifier based on the features selected with the new approach is introduced and evaluated in comparison to others. The future usage and improvement on the emotion classifier build is also examined.","PeriodicalId":136720,"journal":{"name":"Eurocon 2013","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124178958","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 these platforms, the FPGAs serve as accelerators of complex algorithms, making it possible to process a vast amount of sensing data in real time. In medical applications that rely on sensors, both privacy and security are of utmost importance. However, the execution of cryptographic primitives on nodes solely based upon microcontrollers clocked at a low frequency can affect the overall power consumption of the platform. In this manuscript, we present the design of a cryptographic accelerator based on FPGA and aimed to be coupled to a microcontroller. It provides the most secure implementation of the IEEE 802.15.4 security suite together with an Elliptic Curve Cryptography (ECC) engine to perform key establishment. Furthermore, we provide a comparison on performance and energy consumption of cryptographic primitives in commercial nodes and in the proposed design. Our results suggest that the controlled execution of cryptographic algorithms on FPGAs clocked at a low frequency improves the performance and energy consumption of the state-of-the-art implementations based on the MICA and Tmote nodes. However, our results also reflect two inherent limitations of this type of design: the very nature of the bus logic can undermine the expected improvement on performance as well as the communication link between the microcontroller and the FPGA can make the platform vulnerable to physical attacks.","PeriodicalId":136720,"journal":{"name":"Eurocon 2013","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070390","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}
