Transfer of learning between unimanual and bimanual rhythmic movement coordination: transfer is a function of the task dynamic.
Under certain conditions, learning can transfer from a trained task to an untrained version of that same task. However, it is as yet unclear what those certain conditions are or why learning transfers when it does. Coordinated rhythmic movement is a valuable model system for investigating transfer because we have a model of the underlying task dynamic that includes perceptual coupling between the limbs being coordinated. The model predicts that (1) coordinated rhythmic movements, both bimanual and unimanual, are organised with respect to relative motion information for relative phase in the coupling function, (2) unimanual is less stable than bimanual coordination because the coupling is unidirectional rather than bidirectional, and (3) learning a new coordination is primarily about learning to perceive and use the relevant information which, with equal perceptual improvement due to training, yields equal transfer of learning from bimanual to unimanual coordination and vice versa [but, given prediction (2), the resulting performance is also conditioned by the intrinsic stability of each task]. In the present study, two groups were trained to produce 90° either unimanually or bimanually, respectively, and tested in respect to learning (namely improved performance in the trained 90° coordination task and improved visual discrimination of 90°) and transfer of learning (to the other, untrained 90° coordination task). Both groups improved in the task condition in which they were trained and in their ability to visually discriminate 90°, and this learning transferred to the untrained condition. When scaled by the relative intrinsic stability of each task, transfer levels were found to be equal. The results are discussed in the context of the perception–action approach to learning and performance

The steel construction of a sports hall
Obsahem bakalářské práce je návrh a posouzení konstrukčních prvků ocelové sportovní haly situované v Liberci. Objekt má obdélníkový půdorys s rozměry 42,0 x 31,2 m a výšku 11,7 m. Nosná konstrukce je tvořena sloupy a obloukovými příhradovými vazníky. Vzdálenost příčných vazeb je 5,25 m. Statický výpočet zahrnuje posouzení hlavních nosných částí včetně detailů a spojů. Konstrukce je navržena z oceli S235 a S355. Opláštění tvoří sendvičové panely.The subject of this bachelor’s thesis is the design and assessment of the structural elements of the steel sports hall, which is situated in Liberec. The plan dimensions of the structure are rectangular 42,0 x 31,2 m. The height of the structure is 11,7 m. The supporting structure consist of columns and arched truss girders. The distance of each cross links is 5,25 m. Statics calculation contains assessment of the main load-bearing parts of the structure, including details and joints. The structure is made of steel class S235 and S355. The cladding consist of sandwich panels.
