Abstract:

Railway sleepers have important roles within the complex railroad. Dynamic interaction among Rail, sleeper and ballast supports are vital for the construction of dynamic model track capable of predicting its responses to impact loads due to wheel flats, wheel burns, irregularities of the rail. Railway track deteriorates over time due to the dynamic loading of passing wheeled vehicle. to ensure the secure passing of trains, the track must well design and managed.The objective of this thesis is to determine the stress in wooden rail sleeper by the considering Ballast, Sub ballast, and soil with

The topic of this diploma thesis is the architectural study of the cycling arena – velodrome – as a part of The Hněvkovský sports ground in Brno-Komárov. The new velodrome is situated next to the existing bicycle motocross ground and serves as a facility for the track cycling, indoor cycling and BMX. The core of the velodrome consists of the 250-meter wooden steeply banked track, which, together with other sports ground’s parameters fits the requirements of International Cyling Uninon for hosting international competitions.

Abstract:

The extraction and recovery of trace organic material from semi-solid and solid matrices is often the slowest and most error-prone step of an analytical method. The conventional liquid extraction techniques for solids and semi-solids materials (Soxhlet) have two main disadvantages. The first, large volumes of organic solvent are required, which can lead to sample contamination and "losses" due to volatilization during concentration steps. The second, to achieve an exhaustive extraction can require several hours to days. With the development of sophisticated instrumentation with detection limi

Abstract:

Optimization and improvement techniques have been employed to improve truck transportation in the forest industry. Most studies in this area focus on log transportation and there is not much literature available on wood chip transportation which is distinct from log transportation in several ways : chip-truck transportation usually considers a longer planning period, requires a more complex driver scheduling, involves strict limitations on truck unloading capacity, and considers service priorities for major suppliers. The objective of this thesis is to model and improve truck transportation of

Abstract:

Incineration is a mainstream strategy for solid waste management in Sweden and all over the world. Improved knowledge and understanding about the distribution of trace elements (in ashes) during incineration, and how trace element partitioning respond to the changes in waste composition, are important in terms of combustion process optimization and plant efficiency. Moreover, determination of chemical association of trace elements in ashes are vital for avoiding environmental concerns and to promote possible reuse.

Experiment har tidigare utförts på materialet och det har visat att en bräda av KL-trä, som idag inte tillverkas, klarar ett högre stämpeltryck än en vanlig bräda av konstruktionsvirke, vilket skulle kunna vara en lösning på problemen vid tryck vinkelrätt fiberriktningen i höga träbyggnader.
