(1,2)-PDS in graphs with the small number of vertices of large degrees
(Wydawnictwa AGH, 2025) Bednarz, Urszula; Pirga, Mateusz
We define and study a perfect $(1,2)$-dominating set which is a special case of a $(1,2)$-dominating set. We discuss the existence of a perfect $(1,2)$-dominating set in graphs with at most two vertices of maximum degree. In particular, we present a complete solution if the maximum degree equals $n-1$ or $n-2$.

»10 praktycznych sposobów na integrację Romów«, czyli analiza współczesnej sytuacji społeczności romskich z perspektywy antropologii darów
(Wydawnictwa AGH, 2014) Witkowski, Maciej
The article is based on the results of ethnographic fieldwork in the local Bergitka Roma settlements in Poland and their social environment conducted over the past three years Roma communities in Poland are currently a subject of intensive interactions with the »mainstream society«, whose aim is socio-economic integration. Just as in the classic study of Marcel Mauss we also have to deal with an expected value exchange here. Mainstream society gives a gift in the form of funds for »integrative practices« and hopes that on the basis of reciprocity, Roma communities abandon those elements of their traditional way of life which can be problematic in a »democratic« and »integrated« society. Ihc exchange of gifts is usually more of a symbolic action than satisfying »objective« needs. It is rather a sign of mutual recognition, a tactic to build social bonds. The text shows how the existing practice of integrating by gifts sometimes leads to moral humiliation.

2-splittable and cordial graphs
(2010) Cichacz-Przeniosło, Sylwia
E. Miller and G. E. Stevens proved in [E. Miller, G. E. Stevens, Some graphs for which even size is sufficient for splittability, Congressus Numerantium 173 (2005), 137–147] the existence of certain families of $2$-splittable caterpillars. In this paper we characterize other families of $2$-splittable caterpillars. Moreover, we show that for some of them there exists a friendly labeling inducing two isomorphic subgraphs.

2D Electrical Resistivity Tomography interpretation ambiguity - example of field studies supported with analogue and numerical modelling
(Wydawnictwa AGH, 2013) Bania, Grzegorz; Ćwiklik, Michał
Single Electrical Resistivity Tomography (ERT) survey was carried out in the Manor and Park Complex in Nowa Huta (Krakow Branice, Poland). It was applied at a small distance and parallel to the longer wall of a monumental building containing an empty 3 m deep basement. Analogue modelling was performed in order to recreate the field study at the proper scale. The laboratory set-up consisted of a water tank where electrodes were mounted to the particular plate, which rested on water surface. The basement model was made out of a non-conducting material. The default and robust inversions were tested and these variants were also considered with the use of numerical modelling. Laboratory experiments have confirmed that zones visible in the interpreted field section are caused by the influence of the building cellar located next to the survey line. Zones of this kind are additionally disturbed by the local geological structure. The experiment has pointed out, among others, that as the distance between the survey line and the underground body increases, the inversion results are still burdened by an object influence. Thus, similar situations can be verified with the use of analogue modelling presented in this paper or 3D numerical one.

3-biplacement of bipartite graphs
(2008) Adamus, Lech; Leśniak, Edyta; Orchel, Beata
Let $G=(L,R;E)$ be a bipartite graph with color classes $L$ and $R$ and edge set $E$. A set of two bijections $\{\varphi_1 , \varphi_2\}$, $\varphi_1 , \varphi_2 :L \cup R \to L \cup R$, is said to be a $3$-biplacement of $G$ if $\varphi_1(L)= \varphi_2(L) = L$ and $E \cap \varphi_1^*(E)=\emptyset$, $E \cap \varphi_2^*(E)=\emptyset$, $\varphi_1^*(E) \cap \varphi_2^*(E)=\emptyset$, where$\varphi_1^*$, $\varphi_2^*$ are the maps defined on $E$, induced by $\varphi_1$, $\varphi_2$, respectively. We prove that if $|L|=p$, $|R|=q$, $3 \leq p \leq q$, then every graph $G=(L,R;E)$ of size at most $p$ has a $3$-biplacement.

3-dimensional surface magnetic susceptibility distributions with depth to investigate anthropogenic pollutants boundary in Abuja Metropolis
(Wydawnictwa AGH, 2016) Jatto, Solomon Sunday; Sule, Peter Ojo; Ahmed, Lawal Aminu
Changes in the magnetic susceptibility of topsoil, especially in urban areas, are greatly affected by the deposition of anthropogenic metallic dust arising from industrial activities, the burning of fossil fuels, car wear, and tyre abrasion. In this study, magnetic susceptibility measurements were carried out in vertical soil profiles of 30.0 cm depth from the surface at 10.0 cm intervals in about 431 locations within the Abuja metropolis with a view to investigate the penetration ability of magnetic pollutants in the ground. From the obtained data, 3-D surface contour maps were plotted for different depths. The results show a magnetic susceptibility decrease from the surface down the ground to the depth of 30.0cm, most of the recorded susceptibilities were of an anthropogenic origin rather than pedogenic activities. This indicates that the anthropogenic dust depositions are mostly a surface phenomenon and may therefore not pose a risk to groundwater aquifers and near surface wells.

3D block modelling of the Sin Quyen IOCG deposit, North Vietnam
(Wydawnictwa AGH, 2023) Dương Văn, Hào; Nguyẽ̂n, Dinh Chau; Klityński, Wojciech; Zygo, Władysław; Nowak, Jakub
The IOCG Sin Quyen deposit is located in the Red River shear zone of North Vietnam. The ore bodies are known as hydrothermal veins and are hosted in Proterozoic metapelite. A block modelling approach was used to build a 3D model of the ore bodies. An analysis was carried out on Surfer® 11 computer software using the archival data recorded from several dozen boreholes distributed within the study area, as well as data obtained from the mineral and chemical analysis of 50 samples collected recently in the deposit. The ore bodies generally trend in a NW-SE direction with an average azimuth of 107° and dip of around 70°. The Cu content in the ore bodies is inhomogeneous. In the bed extension direction, the exponential correlation of Cu concentration in ore bodies is recognized within 2,500 m, while in the direction perpendicular to the bed strike, the exponential dependence is observed on 500 m of distance. The high-grade mineralisation of copper within the ore bodies is often at the altitude interval from ∼100 m to ∼150 m above sea level (asl). These bodies are also rich in uranium and gold bearing minerals. The total resources of Cu, U and Ag were estimated and amount to 361,000; 12.7 and 11.87 tonnes respectively. The model indicates the downward extension of some ore bodies to below 300 m beneath the ground surface.

3D marine cadastral system to support marine spatial planning implementation in Indonesia - a case study of Penanjung Bay, Indonesia
(Wydawnictwa AGH, 2023) Kurniawan, Agung; Pranowo, Widodo Setiyo; Hardjo, Karen Slamet; Santoso, Agus Iwan; Khakhim, Nurul; Purwanto, Taufik Hery; Setiyadi, Johar
The ocean is a formation that has a volume and consists of a surface layer of water, a column, and a bottom. Visualization of the sea on a digital map is important to support the acceleration of marine spatial planning (MSP), which is generally two-dimensional on a flat plane. A marine cadastre is defined as an instrument used in managing spatial boundaries, which describes, visualizes, and realizes legally defined boundaries as well as rights, restrictions, and responsibilities related to activities in the marine environment. Therefore, visualization in 3D will open a wider perspective than conventional maps. The 3D marine cadastral system was built using the Penanjung Bay pilot project and the QGIS2ThreeJS plugin with JavaScript. The results obtained can provide a 3D visualization of the position and boundaries for each component of the marine cadastre in Penanjung Bay with a broader picture of the sea spatial layout in the region.

3D Microstructure Reconstruction of Tetragonal Zirconia Polycrystalline
(AGH University Press, 2025) Grabowski, Grzegorz
The microstructure of a material is fundamental to its properties and behavior under mechanical and thermal loads. Understanding the internal structure of a material and controlling the microstructure at the stage of ceramic materials synthesis are essential for designing materials with desired properties. This study focuses on the three-dimensional reconstruction of the microstructure of yttria-stabilized tetragonal zirconia polycrystalline (TZP). The goal was to create accurate digital models of the microstructure which could be used for further material analysis. The study utilized images obtained through scanning electron microscopy (SEM), on the basis of which the fundamental stereological parameters were determined. The microstructure reconstruction was performed using the Laguerre tessellation method, allowing for the generation of three-dimensional digital models of the microstructure that represent the material’s internal structure. The results confirm that, based on the basic stereological parameters obtained from two-dimensional cross-sections, three-dimensional reconstruction of the microstructure of polycrystalline zirconia is possible. This work, therefore, represents a step towards the effective design of ceramic materials with high performance parameters, through the control and optimization of their microstructure.

3D spatial analysis of temporal maintenance for multi-use high-rise buildings - case study
(Wydawnictwa AGH, 2024) Mehmood, Usman; Salleh, Syahiirah; Ujang, Uznir; Azri, Suhaibah; Choon, Tan Liat
Urbanization has sparked an increase in the construction of multi-use highrise buildings which consists of commercial parcels on their lower floors and residential parcels on their higher floors. In contrast to conventional landed houses, the residents of high-rise buildings share common facilities and private parcels or spaces also differ according to ownership or use. The management and maintenance of these spaces are dependent on the ownership of the parcel where each ownership adheres to different rights, restrictions, and responsibilities (RRRs). Therefore, accurate representation and identification of those parcels affected by maintenance or renovation is crucial for assisting management bodies to improve the quality of life within a multi-use high-rise building. This study attempts to implement a temporal maintenance management for highrise building parcels within a 3D spatial database. A 3D space segmentation was done to analyze the ownership and use of space in a high-rise building. Spatial queries were also performed based on the temporal maintenance of the parcels, in addition, 3D spatial relationships were used to determine adjacent parcels that were affected by the maintenance. Thus, the implementation of temporal strata database management with an accurate 3D representation of the space can provide management bodies with concise and comprehensive information on parcels with respect to ownerships and uses.

3D technologies as the future of spatial planning - the example of Krakow
(Wydawnictwa AGH, 2020) Bieda, Agnieszka; Bydłosz, Jarosław; Parzych, Piotr; Pukanská, Katarína; Wójciak, Ewelina
The main goal of the paper is to make a general assessment of the application of 3D technologies in spatial planning. It was performed with the city of Krakow as the case study. The paper describes the outline of the spatial planning system in Poland and the planning conditions of Krakow. The data obtained from laser scanning for Krakow are also briefly characterized. The possibility of using these data for locating high-rise buildings in terms of the protection of Krakow's panorama and within two programs »IT system of the Country's Protection Against Extreme Hazards« (ISOK) and »Integrated spatial data monitoring system for air quality improvement in Krakow« (MONIT-AIR) were analyzed in the paper. The main result of the research is the assessment of what studies or measurements may be used to meet particular spatial planning needs or requirements.

4’ 33’’: John Cage’s utopia of music
(Wydawnictwa AGH, 2016) Palmowski, Michał
The present article examines the connection between Cage’s politics and aesthetics, demonstrating how his formal experiments are informed by his political and social views. In 4’33’’, which is probably the best illustration of Cage’s radical aesthetics, Cage wanted his listeners to appreciate the beauty of accidental noises, which, as he claims elsewhere, »had been discriminated against« (Cage 1961d: 109). His egalitarian stance is also reflected in his views on the function of the listener. He wants to empower his listeners, thus blurring the distinction between the performer and the audience. In 4’33’’ the composer forbidding the performer to impose any sounds on the audience gives the audience the freedom to rediscover the natural music of the world. I am arguing that in his experiments Cage was motivated not by the desire for formal novelty but by the utopian desire to make the world a better place to live. He described his music as »an affirmation of life – not an attempt to bring order out of chaos nor to suggest improvements in creation, but simply a way of waking up to the very life we’re living, which is so excellent once one gets one’s mind and desires out of its way and lets it act of its own accord« (Cage 1961b: 12).;John Cage

A bi-objective portfolio optimization with conditional value-at-risk
(2010) Sawik, Bartosz
This paper presents a bi-objective portfolio model with the expected return as a performance measure and the expected worst-case return as a risk measure. The problems are formulated as a bi-objective linear program. Numerical examples based on 1000, 3500 and 4020 historical daily input data from the Warsaw Stock Exchange are presented and selected computational results are provided. The computational experiments prove that the proposed linear programming approach provides the decision maker with a simple tool for evaluating the relationship between the expected and the worst-case portfolio return.

A Big Data processing strategy for hybrid interpretation of flood embankment multisensor data
(Wydawnictwa AGH, 2016) Chuchro, Monika; Franczyk, Anna; Dwornik, Maciej; Leśniak, Andrzej
The assessment of flood embankments is a key component of a country’s comprehensive flood protection. Proper and early information on the possible instability of a flood embankment can make it possible to take preventative action. The assessment method proposed by the ISMOP project is based on a strategy of processing huge data sets (Big Data). The detection of flood embankment anomalies can take two analysis paths. The first involves the computation of numerical models and comparing them with real data measured on a flood embankment. This is the path of model-driven analysis. The second solution is data-driven, meaning time series are analysed in order to detect deviations from average values. Flood embankments are assessed based on the results of model-driven and data-driven analyses and information from preprocessing. An alarm is triggered if a critical value is exceeded in one or both paths of analysis. Tests on synthetic data demonstrate the high efficiency of the chosen methods for assessing the state of flood embankments.
