The effect of temperature on bacterial self-healing processes in building materials
(IOPscience, 2020)
This paper is focused on the bacterial induced calcitation for the crack healing. The bacteria applied for this purpose are from group which is adapted for growth in the high pH environment as a concrete in hydration phase ...
Development of Urban Electric Bus Drivetrain
(ERGO NOMEN, 2019)
The development of the drivetrain for a new series of urban electric buses is presented in the paper. The traction and design properties of several drive variants are compared. The efficiency of the drive was tested using ...
Scientific astrophysical payloads for pico and nano-satellites
(SISSA-The International School for Advanced Studies, 2014)
The picosatellites, recently in development at many institutes and universities (e.g. Schmidt et al. 2009 and Schilling 2006), require a miniaturized payload. We present and discuss an idea for a suitable scientific payload, ...
Digitized Astronomical Photographic Archives as Large Area Sky Survey of Large Amount of Astronomical Data
(SISSA-The International School for Advanced Studies, 2014)
We report here on an investigation of astronomical plate archives and tests of the scanning devices for digitization of archival astronomical plates. These archives represent huge database of
historical astronomical data, ...
Climate at ecologically relevant scales: A new temperature and soil moisture logger for long-term microclimate measurement
(Elsevier, 2019)
Climate measurements are needed at a scale at which organisms live and die. Currently available climate sensors, however, are not well suited for long-term field measurements at such a scale. We have therefore developed a ...
Optimal unions of hidden classes
(Physica-verlag, 2019)
The cluster analysis is a traditional tool for multi-varietal data processing. Using the k-means method, we can split a pattern set into a given number of clusters. These clusters can be used for the final classification ...
Využití fotografie při ověřování proslunění
(Společnost pro techniku prostředí, 2020)
Proslunění bylo v minulosti možné stanovit či ověřit pouze pomocí grafických pomůcek. Využívány byly diagramy slunečních drah pro ruční použití i diagramy implementované do počítačových programů. V poslední době je možné ...
Riziko křehkého porušení železobetonových prvků konstrukčně vyztužených na účinky smyku a kroucení
(BETON TKS, 2020)
V oblastech železobetonových konstrukčních prvků, kde nevzniknou trhliny od posouvající síly a/nebo krouticího momentu, není dle ČSN EN 1992 třeba počítat smykovou výztuž a postačuje provést pouze minimální (konstrukční) ...
Affiliation of Optimum Risk Engineering Tools to technical Facility Management Main Targets Achievement
(IARAS, 2020)
: THE STUDY OF ACCIDENTS AND FAILURES OF COMPLEX TECHNICAL FACILITIES HAS SHOWN THAT IN MANY CASES, THESE PHENOMENA OCCUR WHEN THE TECHNICAL FACILITY INTEGRAL RISK EXCEEDS THE CERTAIN CRITICALITY RATE, I.E. ALSO IF LARGER ...
Destructive and non-destructive experimental investigation of polypropylene fibre reinforced concrete subjected to high temperature
(Elsevier, 2019)
Long-term exposure to high temperature results in the change in both strength properties and mechanical behaviour of concrete. The aim of this paper was to focus on the performance of selected concrete composites, particularly ...
