Inom kanotsporten är synkronisering av paddeltag i en kanot med fler än en kanotist väldigt viktig för att uppnå en så hög hastighet som möjligt. Hans Rosdahl från Gymnastik- och Idrottshögskolan har därför gett i uppdrag att utveckla en mobilapplikation som ger respons till kanotisten som använder applikationen om dennes paddeltag är synkroniserad med frontkanotisten. En förstudie har därför utförts för att bland annat undersöka de olika sensoralternativen som fanns tillgängliga och en applikation inom operativsystemet Android har utvecklats. Applikationen ansluter sig till IMU-sensorer, Intertial Measurement Unit, som sitter på varje paddel och som mäter tröghetskrafterna för att bestämma orientering av sensorn. Applikationen tar emot IMU-data från sensorerna som sitter på användarkanotistens och frontkanotistens paddlar och varje sensor avgör när ett paddeltag har utförts genom orienteringen på sensorn. Denna sensordata som visar ett utfört paddeltag används för att beräkna tidsskillnaden är på paddeltagen från båda kanotister. När tidsskillnaden har räknats ut får användaren visuell respons på mobilskärmen om denne är synkroniserad med frontkanotisten eller inte och på vilken nivå synkroniseringen ligger. / Synchronisation of paddle stroke is an important aspect within the sports of paddling with multiple paddles in one boat to maximise the velocity. Hans Rosdahl from The Swedish School of Sport and Health Sciences, GIH, therefore provided a task to develop a mobile phone application that offers feedback to the paddlers using the application if their paddle stroke is synchronised with the paddler in front. A pre-study has been carried out to investigate possible sensor alternatives that are available, and an application has been developed for the mobile operative system Android. The application connects to an IMU, Inertial Measurement Unit, sensor that measures inertia to determine the orientation of the sensor node. The application receives sensor data from the IMU from the user paddler’s and the front paddler’s sensor nodes and each sensor determines when a paddle stroke has occurred using its orientation. The data showing a stroke is used to calculate the time difference between these strokes to evaluate if the user is synchronised with the front paddler or not. After this evaluation, the user receives a visual response of their synchronisation level on their screen.

Two trigonal tritopic ligands with different conformational degree of freedom: conformationally labile H3tcbpa (tris((4-carboxyl)phenylduryl)amine) and conformationally obstructed H3hmbqa (4,4′,4′′-(4,4,8,8,12,12-hexamethyl-8,12-dihydro-4H-benzo[9,1]quino-lizino[3,4,5,6,7-defg]acridine-2,6,10-triyl)tribenzoic acid) are assembled with square-planar paddle-wheel nodes with the aim of selective engineering of the frameworks with tbo and pto underlying net topologies. In the case of H3tcbpa, both topological types were obtained forming non-interpenetrated MOFs namely DUT-63 (tbo) and DUT-64 (pto). Whereas synthesis of DUT-63 proceeds under typical conditions, formation of DUT-64 requires an additional topology directing reagent (topological modifier). Solvothermal treatment of the conformationally hindered H3hmbqa ligand with the Cu-salt results exclusively in DUT-77 material, based on the single pto net. The possibility to insert the salen based metallated pillar ligand into networks with pto topology post-synthetically results in DUT-78 and DUT-79 materials (both ith-d) and opens new horizons for post-synthetic insertion of catalytically active metals within the above-mentioned topological type of frameworks.
