Skibot 1.0, a Poling Cross-Country Skiing RobotKalliorinne, Otto January 2022 (has links)
This thesis project covers the development of a cross country skiing robot, with the purpose of being used as an instrument for measuring gliding properties of skis. The robot used in total 4 servomotors to control the motion of right and left arms with poles attached. A general movement pattern generator was developed to construct patterns that resemble the one of a human hand during poling. The final robot is able to generate a poling motion resulting in a forward propulsion, but further development to the design has to be made to use the robot for its intended purpose.

Formal Verification of Hardware Peripheral with Security Property / Formell verifikation av extern hårdvara med säkerhetskravYao Håkansson, Jonathan, Rosencrantz, Niklas January 2017 (has links)
One problem with computers is that the operating system automatically trusts any externallyconnected peripheral. This can result in abuse when a peripheral technically can violate the security model because the peripheral is trusted. Because of that the security is an important issue to look at.The aim of our project is to see in which cases hardware peripherals can be trusted. We built amodel of the universal asynchronous transmitter/receiver (UART), a model of the main memory(RAM) and a model of a DMA controller. We analysed interaction between hardware peripherals,user processes and the main memory.One of our results is that connections with hardware peripherals are secure if the hardware is properly configured. A threat scenario could be an eavesdropper or man-in-the-middle trying to steal data or change a cryptographic key.We consider the use-cases of DMA and protecting a cryptographic key. We prove the well-behavior of the algorithm. Some error-traces resulted from incorrect modelling that was resolved by adjusting the models. Benchmarks were done for different memory sizes.The result is that a peripheral can be trusted provided a configuration is done. Our models consist of finite state machines and their corresponding SMV modules. The models represent computer hardware with DMA. We verified the SMV models using the model checkers NuSMV and nuXmv. / Målet med vårt projekt är att verifiera olika specifikationer av externa enheter som ansluts till datorn. Vi utför formell verifikation av sådan datorutrustning och virtuellt minne. Verifikation med temporal logik, LTL, utförs. Specifikt verifierar vi 4 olika use-case och 9 formler för seriell datakommunikation, DMA och virtuellt minne. Slutsatsen är att anslutning av extern hårdvara är säker om den är ordentligt konfigurerad.Vi gör jämförelser mellan olika minnesstorlekar och mätte tidsåtgången för att verifiera olika system. Vi ser att tidsåtgången för verifikation är långsammare än linjärt beroende och att relativt små system tar relativt lång tid att verifiera.

Genetically Engineered Adaptive Resonance Theory (art) Neural Network ArchitecturesAl-Daraiseh, Ahmad 01 January 2006 (has links)
Fuzzy ARTMAP (FAM) is currently considered to be one of the premier neural network architectures in solving classification problems. One of the limitations of Fuzzy ARTMAP that has been extensively reported in the literature is the category proliferation problem. That is Fuzzy ARTMAP has the tendency of increasing its network size, as it is confronted with more and more data, especially if the data is of noisy and/or overlapping nature. To remedy this problem a number of researchers have designed modifications to the training phase of Fuzzy ARTMAP that had the beneficial effect of reducing this phenomenon. In this thesis we propose a new approach to handle the category proliferation problem in Fuzzy ARTMAP by evolving trained FAM architectures. We refer to the resulting FAM architectures as GFAM. We demonstrate through extensive experimentation that an evolved FAM (GFAM) exhibits good (sometimes optimal) generalization, small size (sometimes optimal size), and requires reasonable computational effort to produce an optimal or sub-optimal network. Furthermore, comparisons of the GFAM with other approaches, proposed in the literature, which address the FAM category proliferation problem, illustrate that the GFAM has a number of advantages (i.e. produces smaller or equal size architectures, of better or as good generalization, with reduced computational complexity). Furthermore, in this dissertation we have extended the approach used with Fuzzy ARTMAP to other ART architectures, such as Ellipsoidal ARTMAP (EAM) and Gaussian ARTMAP (GAM) that also suffer from the ART category proliferation problem. Thus, we have designed and experimented with genetically engineered EAM and GAM architectures, named GEAM and GGAM. Comparisons of GEAM and GGAM with other ART architectures that were introduced in the ART literature, addressing the category proliferation problem, illustrate similar advantages observed by GFAM (i.e, GEAM and GGAM produce smaller size ART architectures, of better or improved generalization, with reduced computational complexity). Moverover, to optimally cover the input space of a problem, we proposed a genetically engineered ART architecture that combines the category structures of two different ART networks, FAM and EAM. We named this architecture UART (Universal ART). We analyzed the order of search in UART, that is the order according to which a FAM category or an EAM category is accessed in UART. This analysis allowed us to better understand UART's functionality. Experiments were also conducted to compare UART with other ART architectures, in a similar fashion as GFAM and GEAM were compared. Similar conclusions were drawn from this comparison, as in the comparison of GFAM and GEAM with other ART architectures. Finally, we analyzed the computational complexity of the genetically engineered ART architectures and we compared it with the computational complexity of other ART architectures, introduced into the literature. This analytical comparison verified our claim that the genetically engineered ART architectures produce better generalization and smaller sizes ART structures, at reduced computational complexity, compared to other ART approaches. In review, a methodology was introduced of how to combine the answers (categories) of ART architectures, using genetic algorithms. This methodology was successfully applied to FAM, EAM and FAM and EAM ART architectures, with success, resulting in ART neural networks which outperformed other ART architectures, previously introduced into the literature, and quite often produced ART architectures that attained optimal classification results, at reduced computational complexity.
