Vienna Point I Brno - upper rough construction

Cílem mé bakalářské práce je stavebně-technologické řešení vrchní hrubé stavby objektu Vienna Point I. Konkrétní řešení závisí na vhodné volbě pracovního postupu pro montáž ocelové konstrukce, který bude v ideálním poměru nákladů a časové náročnosti. Pracovní postup z velké míry ovlivní strojní sestava, širší dopravní vztahy a zařízení staveniště.The aim of my thesis is the construction and technological solutions upper shells of buildings Vienna Point I. The specific solution depends on an appropriate choice of the workflow for the erection of steel structure, which will be an ideal cost and time involved. Workflow largely affect the mechanical assembly, wider transport links and site equipment.

Campus MU Brno (green stage) - construction technological project

Předmětem této diplomové práce je řešení stavebně technologického projektu pro hlavní technologické etapy stavby Univerzitní kampus Bohunice (zelená etapa). Jedná se o stavbu složenou z devíti pavilonů, které jsou mezi sebou vzájemně propojeny dvěma koridory. Koridory současně spojují stavbu zelené etapy s předchozí modrou etapou. Všechny stavební objekty jsou částečně podsklepeny a se třemi nadzemními podlažími. Výjimku tvoří SO IV-309, který je tvořen čtyřmi nadzemními podlažími s opláštěním tvaru eliptického válce s plochou střechou uprostřed střešního opláštění. V diplomové práci se zabývám konkrétněji právě tímto stavebním objektem, který jsem řešil z hlediska časového, finančního, technologického postupu vrtaných pilot a zařízení staveniště. Ostatní části projektu jsou navrženy na celou stavbu.The subject of this thesis is the solution of building technology project for the construction of the main processing stages University Campus Bohunice (green stage). It is a building consisting of nine pavilions which are mutually connected by two corridors. Corridors simultaneously combine green building stage with blue previous stage. All buildings are partial basement and three floors. Exceptions are SO IV-309, which consisted of four storeys with casing of an elliptic cylinder with a flat roof in the middle of the roof sheathing. In my thesis I deal specifically this very building object, which I discussed in terms of time, financial, technological progress bored piles and building equipment. Other portions are designed to project the whole building.

Soil Microbial Communities and Enzyme Activities after Long-Term Application of Inorganic and Organic Fertilizers at Different Depths of the Soil Profile

Fertilization is a key factor for sustaining productivity in agroecosystems. A long-term experiment in cambisol following periodical application of several types of fertilization has been running at the experimental site since 1954. In this study, we determined the impact of applied inorganic and/or organic fertilizers on the activity of soil enzymes and on the structure of microorganisms at depths of 0-30 cm and 30-60 cm. Single-factor comparison showed that use of inorganic and/or organic fertilizer had an insignificant e_ect on the activities of soil enzymes (at depths 0-30 cm and 30-60 cm) and also on the structure of microbial communities at both depths studied. Only soil respirations exhibited stimulation by combined fertilization. The results, irrespective of sampling depth (0-60 cm), showed that application of combined organic and inorganic fertilization stimulated the activity of glucosidases and use of inorganic fertilizer inhibited the activity of arylsulphatases. Respirations were stimulated by application of organic fertilizer and combined fertilization. Nevertheless, principal component analyses, which calculate with multidimensional data, revealed di_erences in samples treated by sole mineral fertilizer compared to other variants, especially in the lower layer. In general, our results indicate that use of combined fertilization may improve biological characteristics in deeper parts of soil profile and possibly increase biological activity in agroecosystems.O

Impulzní neuronové sítě pro klasifikaci dat z rozhraní mozek-počítač a obrazových dat

Impulzní neuronové sítě jsou slibným konceptem nejen z hlediska lepší simulace biologických neuronových sítí, ale také z hlediska překonání současných nevýhod umělých neuronových sítí, jako je vysoká spotřeba energie nebo pomalá doba odezvy. Článek se zaměřuje na potenciální přínosy impulzních neuronových sítí při klasifikaci evokovaných komponent zpracovávaných v mnoha tradičních experimentech rozhraní mozek-počítač. Jsou prezentovány experimenty s různými architekturami impulzních neuronových sítí a dále optimalizačními přístupy nad datovými sadami rozhraní mozek-počítač a obrazovými datovými sadami. Dosažené výsledky jsou uvedeny a diskutovány. Nejlepší dosažená přesnost byla 64,86 % pro datovou sadu evokovaných komponent a 97,09 % pro obrazovou datovou sadu.Spiking neural networks are a promising concept not only in terms of better simulation of biological neural networks but also in terms of overcoming the current disadvantages of artificial neural networks, such as high energy consumption or slow response time. The paper focuses on the potential benefits of spiking neural networks in the classification of event-related components processed in many traditional brain-computer interface experiments. Experiments with various spiking network architectures and optimization approaches over specific brain-computer interface and image datasets are presented, and their results are provided and discussed. The best accuracy achieved was 64.86% for the event-related component dataset and 97.09% for the image dataset

The energetic use possibilities of wood from apple tree pruning and some other

Effect of Growing <i>Miscanthus x giganteus</i> on Soil Microbial Communities in Post-Military Soil

Growing a second generation energetic plant Miscanthus x giganteus (Mxg) in former military sites appears to be a promising way to use such areas with synergic phytoremediation of contaminants (organic pollutants, potential toxic metals). Effect of Mxg growth on soil microbial communities during a two-year pot experiment with real post-military soil (Sliač, Slovakia) and the effect of potential toxic metal concentration was studied by analyses of microbial activities and phospholipid fatty acids (PLFA). Year-on-year positive changes in microbial community structure and state were detected (higher ratios of G+/G&#8722; bacteria and fungal/bacterial PLFA, and a decrease of stress indicators trans/cis and cy/pre PLFA). Portion of gram-positive bacteria correlated negatively with potential toxic metal concentrations; however, the concentration of potential toxic metals was not identified as the main stress factor&#8212;the access to bioavailable nutrients was more important. Overall, Mxg growth generally exhibited a positive effect on soil microorganisms
