aE Journal 2015/2016: aE/INTECTURE innovating architecture
No full textThe graduation studio of Architectural Engineering focuses on the integration of (new) technology in architecture. For this purpose, the name aE/ INTECTURE® was devised, which will be developed further as a brand in the coming years. Students start with a technical fascination and translate this into an architectural concept, finally being able to implement this within the environment in a responsible way. ‘If technology is the answer, what is the question?‘ Under the guidance of a team of enthusiastic (guest) lecturers, students search for the dot on the horizon that is necessary for coming up with solutions that improve the quality of the built environment and make it more sustainable. In addition, either the ‘making‘ (make) or ‘the energy and material flow’ (flow) is used and applied as a basis in different contexts.Architectural Engineerin
Condition Monitoring of Helical Gears Using Acoustic Emission (AE) Technology
No full textTechniques such as vibration monitoring, thermal analysis and oil analysis are well
established as means to have been used to improve reliability of gearboxes and extend
time-to-failure. In this area Acoustic Emission (AE) technology is still in its infancy but
the attention shown by researchers towards this method has increased dramatically
because several studies have shown the AE offers the important advantage of improved
sensitivity over more conventional monitoring tools for the early detection and
prediction of gear failure.
Helical gear lubrication is critically important for maintaining the integrity of operating
gears and the oil also prevents asperity contact at the gear mesh thereby protecting the
gears from a deterioration process and surface failures. In gear systems, there are three
types of lubrication regimes: Dry Running, Boundary Lubrication (BL), Hydrodynamic
Lubrication (HL) and Elastohydro-dynamic Lubrication (EHL). The last regime is
associated with the normal operating running condition of gears.
Acoustic emissions were acquired from gears and analysed for different lubrication
regimes (dry, BL, HL and EHL regimes at different temperatures), and corresponding
specific film thicknesses (λ) levels. The results showed an inverse relationship between
AE signal levels and specific film thickness (λ) of the oil. This relation was used to
determine the lubrication regime from the measured AE signals. For instance, dry
running had the highest AE levels which were attributed to the metal-to-metal contact of
the gear mesh. The BL regime had relatively high AE levels which also attributed to the
level of asperity contact is greater than the oil film thickness. The HL regime was
characterized by the lowest AE levels due to the lubricant oil completely separating the
teeth during gear meshing. Finally, the EHL regime showed intermediate AE levels
compared to the BL and HL regimes because the oil film was less than for the HL
regime but greater than for the BL regime.
It is shown that the application of advanced signal processing methods is necessary for
monitoring helical gears; Kurtosis and Spectral Kurtosis were used to investigate the
AE signatures and found to be effective in de-noising (spectral kurtosis) acquired
signals. Acoustic Emission proved to be a powerful tool to detect the oil regime for both
defective and non-defective conditions.
It is concluded that the experimental findings of this research programme will provide
the foundations for significant advancement in the application of AE for the
determining the lubrication regime present within a helical gearbox and for the detection
of developing gear faults. This should give a new impetus in the field of maintenance
and prevention of human and material catastrophes.
Several papers presenting the findings of this research have been published in
international journals and given at conferences
aE Journal 2017/2018: aE/Intecture innovating architecture
No full textDriven by the need to think differently about resources, energy, power generation, the choice of materials, and user involvement, we see the built environment in a new perspective. The program, Architectural Engineering, seeks for innovative and inspiring architectural solutions for social and environmental issues throughout all scales.To achieve this, innovation of the architectural challenge is high on our agenda. Innovation is more than just a technical improvement. How do you implement new current issues in modern architecture? We anticipate new energy, materials, and circularity. We also use the current environment of the metropolis and the countryside. We add new buildings, strengthen existing stock, and work on new components of buildings. From high to low tech. From digital to traditional, looking carefully to the context.Architectural Engineerin
Main motifs in the prose of the leftist author Kang Kyŏng-ae
No full textThe subject of this bachelor thesis is the life and work of the Korean writer Kang Kyǒng-ae, with a focus on her short prose. The aim of this thesis is an analysis of two works - Salt and Darkness - with attention to the context of the author's time. Nowadays, Kang Kyǒng-ae is considered a significant author of the 1930s and her works reflect the phenomenon of Korean emigrants in Manchuria. For a long time, leftist tendencies caused her prose to be neglected, which resulted in a considerably limited number of studies concerned with her work, in comparison to the number of studies about other writers. There are virtually no Czech studies of her work. The text of the thesis initially presents the timeframe of Kang's authorship and then analyzes select works of hers. The analysis of the works focuses on recurring motifs, which are put into a historical and social context. Keywords Kang Kyǒng-ae, Korean 1930s literature, leftist literature, Sogǔm, Ǒdu

Autour du Nepos d'Alburnus, Maior, Panes, fils de Bizo (AE, 20081167=AE, 2007, 1201) : petit-fils ou neveu
No full textInternational audienceIn this article, the author studies again the inscription on a stone of a nepos from Alburnus Maior: Panes, son of Bizo (AE, 2008, 1167 = AE,2007, 1201). If the word nepos very often means « grandson », there are cases where it means « nephew ». The author pays special attention to the Latin kinship terminology in this inscription because names and lines are not Roman but peregrine. So, there is ambiguity as we cannot exactly know the relations between all these names. Now, between a grandfather and his grandson or an uncle and his nephew, there is the same number of generations. It is necessary for one to compare these to other inscriptions and words in addition to nepos (auia, auus, nurus, gener, pater, mater) or only with nepos in Rhenodanubian provinces (Raetia, Pannoniae, Moesiae, Dacia): these 67 inscriptions are in an appendix.The author concludes that the these two possibilities exist here
