Diagnostic methods for the evaluation of the state of timber structures
Nguyen, Martin ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
This bachelor‘s thesis is focused on description and evaluation of selected diagnostic methods used for a survey of timber structures. The first part describes the structure and properties of wood, damaged by external factors and protection. Another part provides a description of non-destructive, semi-destructive and destructive methods of diagnosis. The practical part applies the selected diagnostical methods on specific particular element of a wooden construction. The aim of this bachelor’s thesis is to become familiar with the survey proces timber elements, verification and their application in practice.

Wood processing processes and problems of production technology of semi-finished products
Šimo, Samuel ; Osička, Karel (referee) ; Chladil, Josef (advisor)
The diploma thesis is focused on the optimization of a new production line of the woodprocessing factory DCP Timber. In the first part, the work approaches wood in terms of itsinternal structure and its physical and mechanical properties. The second part is focused on themost common methods of cutting the wood material. The third part describes the technology ofconvection drying of wood and the impact of this drying on the resulting quality of woodensemi-finished products. The practical part of the thesis is the solution to the inefficientproduction of the machine of the circular saw, which is an important part of the production line.There is a comparison of different cutting tools and their effect on dimensional tolerances. Inthe next point, thanks to mathematical models, the parameters of maximum feed speed andpower of the electric motor of the spreading saw are determined. Finally, a technical andeconomic evaluation is developed where the payback period is calculated in the case ofinvestment in a power unit with higher performance.
