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
Greedy random adaptive memory programming search for the capacitated clustering problem
No full textIn the capacitated clustering problem (CCP), a given set of n weighted points is to be partitioned into p clusters such that, the total weight of the points in each cluster does not exceed a given cluster capacity. The objective is to find a set of p centers that minimises the total scatter of points allocated to these centers. In this paper, we propose a merger of Greedy Random Adaptive Search Procedure (GRASP) and Adaptive Memory Programming (AMP) into a new GRAMPS framework for the CCP. A learning process is kept in charge of tracking information on the best components in an elite set of GRAMPS solutions. The information are strategically combined with problem-domain data to restart the construction search phase. At early stage of constructions, priorities are given to problem-domain data and progressively shifted towards generated information as the learning increases. GRAMPS is implemented with an efficient local search descent based on a restricted λ-interchange neighbourhood. Extensive experiments are reported on on a standard set of bench-marks from the literature and on a new set of large instances. The results show that GRAMPS has an efficient learning mechanism and is competitive with the existing methods in the literature. © 2003 Elsevier B.V.

Recovery and germination rates of seeds of Mediterranean medics and clovers offered to sheep at a single meal or continuously
No full textMeasurements were made of the recovery and germination rates of seed of eight species of annual medic (Medicago spp.) and three of clover (Trifolium spp.) after ingestion by sheep. Recovery of medic seed was measured as the number of seeds collected from faeces after feeding, in addition to a basal diet, either (i) 200 g of pods at a single meal, or (ii) a quantity of pods estimated to contain 30000 seeds at a single meal or (iii) 200 g of pods daily for 21 days. Only the first method was applied to the clovers. There were large differences (P < 0.001) in seed recovery between species, from < 2 % to nearly 20 % in medics, and up to 59 % in T. campestre, which has low single-seed mass. Although there was a curvilinear decrease in seed recovery as single-seed mass increased (r2 = 0.80), the high recovery of M. rotata, a fairly large-seeded species, suggests that there are important differences between species, irrespective of seed size. When 200 g of medic pods was offered to sheep at a single meal, mean seed recovery was slightly lower than when 200 g of medic pods was offered daily for 21 days. Seed recovery of medics was much higher (P < 0.001) when 30000 seeds were offered at one meal. Germination rate before ingestion was 1.9-6-5 % (P < 0.001) for hard-seeded medics and 2-7-9.7 % (P < 0.001) for clovers with low single-seed mass; passage through the digestive tract increased (P < 0.001) germination rate in both medics and clovers
Response of Mediterranean grassland to phosphate and stocking rates: biomass production and botanical composition
No full textThree rates of phosphate (0, 25, and 60 kg/ha P2O5) were applied phosphorus-deficient native grassland at Tel Hadya, in northern Syria, and biomass productivity, botanical composition and number of legume seeds in the soil were monitored for five seasons (1984/85-1988/89). The experiment was grazed at low (0.8 sheep/ha per year) and high (1.7 sheep/ha per year) stocking rates from the second to the fourth seasons of the experiment; in the fifth season, the low and high stocking rates were increased to 1.1 and 2.3 sheep/ha per year, respectively. The experimental site was typical of native grassland within the cereal zone of west Asia, where cropping is not possible because of shallow, stony soils and steep slopes.
The results showed that annual applications of phosphorus, even as low as 25 kg P2O5/ha, alleviated the deficiency in soil P and resulted in improved pasture production, even in dry years. Legume production showed the greatest response to P, increasing by 0.3-3 times the production of the control treatments. By the fifth season, legume seed mass had increased threefold and number of seeds sixfold in the P-treated plots, compared with the first season, while in the control plots there was little change. Rain-use efficiency on the P-treated plots was more than double that of the controls by the fourth and fifth seasons.
Practical application of the results depends on whether (i) legumes are as frequent in native grasslands, as a whole, as they are at Tel Hadya, (ii) the P deficiency observed at Tel Hadya is widespread, and (iii) grazing of communally owned grasslands can be controlled. It is suggested that all three criteria will often be fulfilled and, therefore, that grassland productivity in west Asia could be substantially increased. Furthermore, the results suggest that above-ground cover and soil organic matter will also increase after P application, both of which will help to reduce soil erosion and thereby increase the sustainability of livestock production in west Asia
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
