A CASE FOR DOMAIN-INDEPENDENT DETERMINISTIC MULTIAGENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)The notion of planning using multiple agents has been around since the very beginning of planning itself. It has been approached from various viewpoints especially in the multiagent systems community. Recently, domain-independent ... -
A case study of implementing a renovation concept
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)There is an untapped potential for reducing GHG emissions by district renovation. It needs a detailed Energy Master Planning (EMP) of the district and support for the decision-making processes. If applied in a comprehensive ... -
A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments. The tension is common reason of failure ... -
A geometry projection method for designing and optimizing additively manufactured variable-stiffness composite laminates
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)A method for designing laminates is presented using geometry projection to optimize the layout of additively manufactured variable-stiffness composite laminates. By considering fiberreinforced bars as geometric primitives, ... -
A guideline to support the use of off-site solutions for façade retrofitting through BIM-enabled processes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The Architecture, Engineering and Construction sector requires an intense innovation process to reduce costs, intervention times, and improve energy performance. This is particularly true to increase the rate of deep ... -
A HEADRACE TUNNEL RECONSTRUCTION IN TURKEY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)The operation of a hydro power project in North Turkey started in 2015, included the 12km long headrace tunnel. An 8km long lower tunnel section was excavated by double shield TBM technology with 8.7m ID. Due to problems ... -
A methodological approach for life cycle assessment of refurbishment measures - from building to neighbourhood and municipal level
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Life cycle assessment (LCA) in the building sector has become a widely used method for quantifying environmental impacts of a building over its entire life cycle. Currently, however, no standardized procedure exists for ... -
A modular extension of a finite element contact implementation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The structural mechanics module of the OOFEM finite element software has been developed to include various algorithms for solving contact mechanics problems. After developing small strain contact algorithms in the 2D domain ... -
A Multi-Wavelength View of the XMM-Newton Galactic Plane
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present an X-ray survey of the Galactic Plane conducted by the Survey Science Centre of the XMM-Newton satellite. The survey contains more than 1300 X-ray detections at low and intermediate Galactic latitudes and covering ... -
A new performance test to evaluate the sulfate resistance of concrete by tensile strength measurements
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Concrete structures without sufficient durability can be damaged by sulfates in groundwater and from surrounding rock layers. To evaluate the performance of a concrete mixture, precise and performance-oriented test methods ... -
A New Review of Old Novae
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)Novae are certainly very exciting at the time of their eruptions, and there is much work left to be done in understanding all of the details of that part of their existence, but there is also much to be learned by looking ... -
