Przydatność różnych typów sieci neuronowych w klasyfikacji gleb
(Wydawnictwa AGH, 2006) Gruszczyński, Stanisław
The application of three neural networks algorithm in task soils classification, on the basis of features obtained from analog cartographic documentation, is presented. The MLP (Multi-Layer Perceptron) type net and PNN (Probabilistic Neural Network) give the best classification results among examined algorithms. The PNN and SOM (Self-Organizing Map) combination of net operational results gives more deep classification relations within sphere this study, based among others on fuzzy relationships visualization between complexes in analyzed area.
Emisja zanieczyszczeń z procesu grafityzacji elektrod węglowych w piecach LWG (Castnera). Część 2. Wybrane substancje pyłowe
(Wydawnictwa AGH, 2006) Mazur, Marian ; Oleniacz, Robert ; Bogacki, Marek ; Szczygłowski, Przemysław
In the paper the measurement results of quantity of dust pollutants originated and emitted to air from resistor stoves of type LWG (Castner) during graphite process of coal electrodes were introduced. The investigation was carried out for total dust, total tar substances and polycyclic aromatic hydrocarbons (PAHs). The measurements were performed both before and after the flue gas control system (catalytic burning and wet cleaning). Thus changes of the substance concentrations in the gases for the cleaning system were estimated. As a result of the investigation was conclusion that the graphite process of coal electrodes in LWG stoves is not a significant source of dust emissions. Although there is occurred increasing of total tar substances and PAHs concentrations in the gases and changing of PAHs profile within the catalytic reactors using for the flue gas burning.
Ocena wpływu remontów oraz zabezpieczeń profilaktycznych na trwałość budynków murowanych w LGOM
(Wydawnictwa AGH, 2006) Wodyński, Aleksander ; Firek, Karol ; Kocot, Wojciech
The paper presents the results of research concerning building impacts, i.e. preventive maintenance conducted by mining companies and renovation work, on the durability of the traditional building development in the Legnica-Głogów Copper District. The basis for the research was an established database containing information about damage, wear and potential causes of damage and anomalies in 930 residential buildings, a typical town, suburban and rural development within the region the traditional masonry structure and 370 farm buildings, mainly barns, stables, and cowsheds. In the research a quantitative analysis was made of the effects of building impacts on the durability of the LGOM building development. An methodology was applied, which involved a comparative analysis of durability estimated on ground time trends of the technical wear of selected groups of buildings. For example, the influence renovation works on the durability was evaluated on the basis of comparative analysis of the progression over time of technical wear of buildings with preventive maintenance. The analysis for the investigated group of renovated buildings showed a relative 12.6% increase in the average durability in comparison with the not renovated buildings. This means that after fifty years of utilization the absolute difference in the average wear would be 4.9%.
Ocena i prognozowanie stanu gleb na potrzeby planów i programów
(Wydawnictwa AGH, 2006) Gruszczyński, Stanisław
The environmental assessment of effects of the plans and programs realization is relatively novelty in Polish Environmental Impast Assessment practice. In the next few years one might await a considerable increase of demand of this kind of studies. The evaluation of the present state and also the prognosis of future soils states needs methodological basis, including the applied procedures settling a reliable description of forecast transformation and their effects. The paper presents some aspects of this problem, putting interest mainly on digital methods data processing and information integration.
Badania właściwości dynamicznych wysokich kominów żelbetowych
(Wydawnictwa AGH, 2006) Oruba, Rajmund
The problem of dynamic measurements of industrial reinforced concrete chimneys H = 100+300 m was described in the paper. These measurements enabled to evaluate natural frequency, vibration forms and vibration damping of this objects. Dynamic characteristics are needed to diagnose and safety evaluation of chimneys. This problem is very important in regions of paraseismic mining shocks, e.g. at Legnicko-Głogowski Copper District (LGOM). The particular notice in the paper was put on the vibration excitation of chimneys in their natural scale. Examples of organization of investigations and arrangement of testing measurement equipments were given. Authors presented dynamic measurement results of 16 high reinforced concrete chimneys.
