  • Effect of uniaxial compression in the transmittance of a novel terahertz sensor for structural health monitoring

    2013 Loughborough Antennas & Propagation Conference (LAPC)

    In this paper we present a study of a novel THz passive wireless micro-sensor that responds to uniaxial compressions. The sensor can work in two different modes of operation, namely, by variations of the resonance frequency or by variations of the intensity of the transmitted signals with respect to the applied compression. We develop a theoretical method to predict the transmittance and resonance frequency of the unit cells of the sensor. This method takes into account the rectangular shape of…

    In this paper we present a study of a novel THz passive wireless micro-sensor that responds to uniaxial compressions. The sensor can work in two different modes of operation, namely, by variations of the resonance frequency or by variations of the intensity of the transmitted signals with respect to the applied compression. We develop a theoretical method to predict the transmittance and resonance frequency of the unit cells of the sensor. This method takes into account the rectangular shape of the wires in the structure, as well as the dispersion and losses. A numerical study is performed which demonstrates that, when the sensor works in the resonance frequency mode, its sensitivity is independent of the number of layers considered and has a value of 380 GHz/μm. In the intensity control mode, the sensor behaves in a non-linear manner and variations in the transmittance of the order of five to ten times are obtained when the sensor is compressed to 70% of its original size.

  • Multiclass Electrooculography Using Common Spatial Pattern

    Telecommunications and Signal Processing (TSP), 2012 35th International Conference on

    In this paper we apply common spatial pattern (CSP) to the classification of electrooculography (EOG) signals with four distinct classes, namely, eye blinks (EB), eye rotation clockwise (ERC), vertical eye movement (VEM) and horizontal eye movement (HEM). We first describe the CSP and Linear Discriminant Analysis (LDA) algorithms with two classes. We apply the classification method to a database with 9 subjects to evaluate the system performance for long trials (15 s) and short trials (3 s). In…

    In this paper we apply common spatial pattern (CSP) to the classification of electrooculography (EOG) signals with four distinct classes, namely, eye blinks (EB), eye rotation clockwise (ERC), vertical eye movement (VEM) and horizontal eye movement (HEM). We first describe the CSP and Linear Discriminant Analysis (LDA) algorithms with two classes. We apply the classification method to a database with 9 subjects to evaluate the system performance for long trials (15 s) and short trials (3 s). In both cases the performance was above 86%. We then generalize the method to the multiclass situation (four classes). It is shown that 100% accuracy is obtained (in the scope of the used data set) when the classifier is trained with 8 subjects and tested with another. Even in the extreme situation, when only one subject is used to train the classifier, the system can perform with an accuracy of 84.3%.

    Being the first ever Google DevFest on Portuguese Territory we intended to elevate and innovate to an international level from the start, developing key competences alongside the international speakers and promoting a spirit of constant learning, giving a broad perspective of the current technologies being used and developed by Google and using them for a greater cause, not only for young students but also for professionals who wish to refresh their knowledge and innovate in their industries with a Google-sized skill set.
