Adapting pipes are a significant part of any pipe-line network and they are the sources of substantial hydraulic losses. They are designed for a manufacturing simplicity, regardless of flow. This paper concerns with lowering of hydraulic losses of adapting pipes by means of the shape optimization. Several methods of a mathematical optimization are tested and due to the complexity of the task and the need of the computational distribution among several computers, the gradient based algorithm is used. These methods loop together with a CFD software then automatically explore the design space. Several optimizations of diffusers with different opening angles, shape parameterizations and boundary conditions are made for the better insight on hydraulic losses. In three chapters there is description of development of parametric description of bend by means of Bezier surfaces. At the end optimum shape is found with hydraulic losses were decreased about 22%, which was not validated by experiment. In the final chapter is application of developed software on the shape optimization of Kaplan draft tube.

In those diploma work work tie together on the work of bachelor degree, in which I'm proposed one-family house frame wood - construction. Thesis treat of production documentation one-family house. Work includes part graphical, that contains project part and production. Here are plotted all peripheral and inner wall and circumscribed all appropriate machinery appurtenances, that concern production documentation. In text parts come out constructive system and his outlines for realization construction. Be here composition construction siding, that are further thermally- technically advised in software -- warm. Work is supplemented about accompanying and technical report.

This thesis was composed for detection and verification available methods determination volume of chopped wood. The results individual methods were comparated out of point of view accuracy among themselves. The main was appraisal applicability individual methods in practice, on particular measurement. In this verification individual methods were found conversion numbers (coefficients) for chopping wood loose fill into a graduated container and conversion numbers for stacked chopping wood. Partial aim of this thesis was determine factors affecting size conversion numbers for loose fill chopping wood and subsequently these factors verified by measurement. This thesis was prepared at the school forest district Valšovice, on which is manufactured and sell chopping wood loose fill from a conveyor belt into a container or tractor tailer.

This diploma thesis deals with four chosen types of vertical sheathing of houses in the passive standard and their overall thermo-technical and economic evaluation. At first, the materials which may be used in wood constructions of vertical sheathing of a house are described. Further, a design and thermo-technical assessment of each of the structures is performed. Wooden structures using environmentally friendly insulation are designed for three types of vertical sheathing and the system Ytong with external insulation is proposed for the fourth type, currently often used in the construction of passive houses in the Czech Republic. In order to comprehensively assess the building envelope, the composition of the roof and floor on the ground will be designed. The other part deals with the evaluation of the building envelope, separately for all four vertical sheathing options. An economic comparison of the envelope options based on the creation of itemized budgets will be carried out. Finally, the pros and cons of using each of the proposed envelope compositions will be evaluated.
