Procedural Generation of 2D Creatures

Käesoleva bakalaureusetöö raames arendati 2D olendite genereerimise süsteem ning selle süsteemi implementatsioon programmeerimiskeeles JavaScript. Süsteem tekitab mitmekesiseid olendeid ning nendega seotud andmed, sealhulgas skelett, geomeetria ja tekstuur. Bakalaureusetöö sisaldab süsteemi kirjeldust. Süsteemi iga sammu kohta on välja toodud tähtsamad põhimõtted ning seletatud mõned implementatsiooni üksikasjad.Töös analüüsitakse süsteemi tervikuna ning selle implementatsiooni. Tuuakse välja süsteemi probleemid ning nõrgad kohad ja mõõdetakse implementatsiooni jõudlust. Töö lõpus tuuakse välja süsteemi kasutusvõimalused ja võimalused selle edasi arendamiseks.The purpose of this thesis is the development of a system capable of generating a large variety of 2D creatures and their associated data, such as skeletons, meshes and textures. A JavaScript implementation of the system was developed for this thesis. This thesis contains a description of the developed system and a description of each step of the generation process and its principles with some additional notes about the specifics of the implementation.The creature generation system as a whole and its implementation are analysed and their advantages and drawbacks brought out. The performance of the implementation is also tested. Several possible improvements are proposed at the end of the thesis, as well as possible uses

Electrochemomechanical Behavior of Polypyrrole-Coated Nanofiber Scaffolds in Cell Culture Medium

Glucose-gelatin nanofiber scaffolds were made conductive and electroactive by chemical (conductive fiber scaffolds, CFS) and additionally electrochemical polypyrrole deposition (doped with triflouromethanesulfonate CF3SO3−, CFS-PPyTF). Both materials were investigated in their linear actuation properties in cell culture medium (CCM), as they could be potential electro-mechanically activated cell growth substrates. Independent of the deposition conditions, both materials showed relatively stable cation-driven actuation in CCM, based on the flux of mainly Na+ ions from CCM. The surprising result was attributed to re-doping by sulfate anions in CCM, as also indicated by energy-dispersive X-ray (EDX) spectroscopy results. Overall, the electrochemically coated material outperformed the one with just chemical coating in conductivity, charge density and actuation response

Comparative Analysis of Fluorinated Anions for Polypyrrole Linear Actuator Electrolytes

Either as salts or room temperature ionic liquids, fluorinated anion-based electrolytes have been a common choice for ionic electroactive polymer actuators, both linear and bending. In the present work, propylene carbonate solutions of four electrolytes of the three hugely popular anions—triflouromethanesulfonate, bis(trifluoromethane)sulfonimide, and hexafluorophosphate were compared and evaluated in polypyrrole linear actuators. The actuation direction, the characteristics—performance relations influence the behavior of the actuators. Isotonic Electro-chemo-mechanical deformation (ECMD) measurements were performed to study the response of the PPy/DBS samples. The highest strain for pristine PPy/DBS linear actuators was found in range of 21% for LiTFSI, while TBAPF6 had the least cation involvement, suggesting the potential for application in durable and controllable actuators. Interesting cation effects on the actuation of the same anions (CF3SO3−) were also observed
