The reconstruction design of timber structures of the existing building
Bartlová, Jana ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The content of this work was to carry out construction-technical survey of timber structures of the existing building in order to design an appropriate procedure for their reconstruction. The survey showed construction in an unsatisfactory to disrepair, so further work also includes the static calculation of new structures proposed instead of the current. Timber structure in the building has form of staircase, roof and ceiling construction. Newly designed the following types of stairs and roof trusses from which the lower belts are used as ceiling beams. The new proposal also includes possible roofing, roofing options, developed one of them. The work also includes drawings, bill of materials and cost estimate staircase structure and truss. Specialization in the field of civil engineering is represented by drawings of the new truss and passport (view of current state) whole object on parcel ST.74 / 1, land Tišnov (okr.Brno-venkov), the content of which was the basis for this work.

Non-destructive Detection Methods of Biological Activities Wood-destroying Insects
Kintr, Jindřich ; Král, Bohumil (referee) ; Fiala, Pavel (advisor)
The subject of this thesis is to study a non destructive methods and methodologies of detection biological wood pests. Analyzed method of detection in this thesis is non destructive acoustic detection. For scanning the activity of wood pests a sensor with piezoelectric converter is used and for scanning the ambient sound a sensor with an electret microphone is used. The signals from these sensors are subtracted in a differential amplifier. In this thesis we can find a method determine the similarity of two signals and a laboratory measuring of detection of activity of a wood pests (Hylotrupes bajulus).

Non-destructive Detection Methods of Biological Activities Wood-destroying Insects
Soja, Radim ; Friedl, Martin (referee) ; Fiala, Pavel (advisor)
This work contains studying the methods of non-destructive detection of activity in the construction of wood-destroying pests structural element . Detection is performed acoustic detection vital activities beetle larvae krovového . To suppress / eliminate unwanted acoustic noise are proposed methods of differential sensing and acoustic signal processing to suppress unwanted signals and are used to four sensors with piezoelectric transducer as the sensing element . The basic idea of the proposed method is to utilize the effect , in which there is between the individual sensors in the read signal to the phase shift . Once you're into the sensor and signal processing of sensor signals are fed to a differential amplifier , and the operation of subtraction .
