This paper refers to the present state of historical buildings situated in the Karviná and Ostrava region and also to the problems of these buildings caused first of all by surface vibrations generated by mining-induced seismicity in the Karviná region and by technical seismicity caused by industrial activities and transportation in the Ostrava region. Designing of earthquake-resistant structur...

This project serves as a literature review on the transformation and synthesis of magnetite from hematite under hydrothermal conditions as well as with Pulsed Laser Deposition (PLD) and milling. Magnetite forms over a similar range of elevated temperatures regardless the method that is used to synthesize it, including nonheterogeneous, loosely controlled environments such as a ceramics kiln. Ba...

Blasting operations generate seismic effects in underground mines. These effects apply additional dynamic loads on the support system, which should bear both static and dynamic loads. Static loads are caused by the weight of the superincumbent strata, while dynamic loads occur as a result of blasting in the mining area. Identification of the origin and determination of the support system behavi...

Structural vibration control is one of the most important features in structural engineering. Real-time information about seismic resultant forces is required for deciding module of intelligent control systems. Evaluation of lateral forces during an earthquake is a complicated problem considering uncertainties of gravity loads amount and distribution and earthquake characteristics. An artificia...

3 This paper investigates the performance of a novel semi-active damping device at mitigating non4 simultaneous multi-hazard loads. The device, termed modified friction device (MFD), has been previously 5 proposed by the authors. It consists of a variable friction system based on automotive drum brake technol6 ogy. The device has been demonstrated in a laboratory environment, and its dynamic be...
