Opis:: W pracy zaprezentowano zastosowanie algorytmów ICP (Iterative Closest Point) i algorytmu SIFT w lokalizacji robota mobilnego. W prowadzonych pracach przyjęto założenie, że robot przemieszcza się w przestrzeni 3D i jest wyposażony w skaner laserowy 3D. Klasyczny algorytm ICP jest czasochłonny, ale połączenie go z algorytmem SIFT znacząco zmniejsza czas obliczeń i jednocześnie zapewnia porównywalną dokładność wyniku. Ponieważ metoda SIFT wymaga zapisywania danych w postaci obrazu zaproponowano kilka metod przekształcenia skanu 3D do obrazu i przetestowano wpływ danej metody na poprawność oraz czas obliczeń.
In this paper the applications of ICP (Iterative Closest Point) algorithm and SIFT algorithm for mobile robot localization are presented. It is assumed that the robot is equipped with 3D laser range scanner and it acts in 3D space. Classical ICP method is time consuming but using SIFT methods for features detection makes the process of localization more effective. Before the process of localization starts the 3D data are transformed into 2D image. In the paper a few method of data transformation are presented. The influence of data transformation in process classification is presented in the paper.

Opis:: Objectives: The method for the determination of As, Al, Cd, Ni, Pb (toxic elements) and Cr, Co, Cu, Fe, Mn, Zn (essential elements) in human urine by the use of Inductively Coupled Plasma Mass Spectrometry (quadrupole ICP-MS DRCe Elan, Perkin Elmer) with the dynamic reaction cell (DRC) was developed. Materials and Methods: The method has been applied for multi-element analysis of the urine of 16 non-exposed healthy volunteers and 27 workers employed in a copper smelter. The analysis was conducted after initial 10-fold dilution of the urine samples with 0,1% nitric acid. Rhodium was used as an internal standard. The method validation parameters such as detection limit, sensitivity, precision were described for all elements. Accuracy of the method was checked by the regular use of certified reference materials ClinCheck®-Control Urine (Recipe) as well as by participation of the laboratory in the German External Quality Assessment Scheme (G-EQUAS). Results: The detection limits (DL 3s) of the applied method were 0.025, 0.007, 0.002, 0.004, 0.004, 0.086, 0.037, 0.009, 0.016, 0.008, 0.064 (μg/l) for Al, As, Cd, Cr, Co, Cu, Fe, Mn, Ni, Pb, Zn in urine, respectively. For each element linearity with correlation coefficient of at least 0.999 was determined. Spectral interferences from some of the ions were removed using DRC-e with addition of alternative gas: methane for cobalt, copper, cadmium, chromium, iron, manganese, nickel and rhodium, and oxygen for arsenic. Conclusions: The developed method allows to determine simultaneously eleven elements in the urine with low detection limits, high sensitivity and good accuracy. Moreover, the method is appropriate for the assessment of both environmental and occupational exposure.

Opis:: A simple procedure using α and γ spectrometry for the determination of natural radionuclides in two Polish geothermal water samples from Mszczonów and Cieplice, as well as in deep well groundwater from the city of Łódź, was described. The 222Rn radionuclide was directly extracted from 10 cm3 water samples to a scintillator solution placed in scintillation vials and determined by an liquid scintillation (LSC) technique with α/β separation. The activity concentrations of three radium nuclides: 228Ra(228Ac), 226Ra(222Rn), 224Ra, as well as 210Pb and 228Th were measured by γ spectrometry with an HPGe detector after their preconcentration on hydrated MnO2. 210Po was deposited on a silver disc from dissolved MnO2 precipitate after γ-spectrometry analysis and measured by α spectrometry. The concentration of 210Pb in the examined samples was below the detection limit of the method (< 6.2 mBq/dm3), whereas activity of its decay product 210Po was in the range 0.35–1.4 mBq/dm3. Higher activities of 228Ra (46.7 mBq/dm3), 226Ra (67.8 mBq/dm3) and 224Ra (22.4 mBq/dm3) were observed for the deep well water in Łódź in comparison to those for geothermal water samples from Cieplice and Mszczonów. However, concentrations of all the measured radionuclides were below World Health Organization (WHO) reference activities (0.1 Bq/dm3 for 228Ra and 1 Bq/dm3 for 226Ra and 226Ra).

Opis:: The Permian carbonate-hosted Farsesh barite deposit is located southeast of the City of Aligudarz in the prov-ince of Lorestan, Iran. Structurally, this deposit lies in the Zagros metallogenic belt and the Sanandaj-Sirjan Zone. Barite mineralisations occur as open-space filling veins, and as massive and replacement ores along fractures, faults and shear zones of the Permian carbonate host rocks. In order to determine the structure, in addition to pe-trographic and fluid-inclusions studies, an ICP-MS analysis was carried out in order to measure the major as well as the trace and rare earth elements. The Farsesh barite deposit has a simple mineralogy, of which barite is the main mineral, followed by calcite, dolomite, quartz, and opaque minerals such as Fe-oxides. Replacement of bar-ite by calcite is common and is more frequent than space-filling mineralisation. Sulphide minerals are minor and mainly consist of chalcopyrite and pyrite, which are altered by weathering to covellite, malachite and azurite. Petrographic analysis and micro-thermometry were carried out on the two-phase liquid/vapour inclu-sions in ellipsoidal or irregularly shaped minerals ranging in size from 5–10 μm. The measurements were conducted on fluid inclusions during the heating and subsequent homogenisation in the liquid phase. The low homogenisation temperatures (200–125°C) and low to moderate salinity (4.2–20 eq wt% NaCl) in-dicate that the barite had precipitated from hydrothermal basinal water with low to moderate salinity. It appears from the major and trace elements that geochemical features such as Ba and Sr enrichment in the barite samples was accompanied by depletion of Pb, Zn, Hg, Cu and Sb. The geochemistry of the rare earth elements, such as low ΣREE concentrations, LREE-enrichment chondrite-normalised REE patterns, the negative Ce and positive Eu anomalies, the low Ce/La ratio and the positive La and Gd anomalies, suggest that the Farsesh barite was deposited from hydrothermally influenced sea water. The Farsesh deposit contains low-temperature hydrothermal barite. The scatter plots of the barite (close to sea water) in different areas on the CeN/SmN versus CeN/YbN diagram support the possibility that the barite was formed from seawater-bearing hydrothermal fluids.

Opis:: In this paper two scanning strategies (stop-scan, continuous scanning) of Small Mobile Mapping System (SMMS) are discussed. SMMS registers 3D scans to provide accurate metric maps. This strategies have been implemented and evaluated in INDOOR environment. First is stop-scan fashion – SMMS stops, acquires data and moves forward to next position. The second approach is scan acquisition during motion. The data acquired in these approaches are registered using GPGPU ICP algorithm. As a result the comparison of the two registered point clouds with ground truth data is demonstrated.

Opis:: The U-Pb system is a useful chronometer for understanding the formation history of chondritic materials. Modern studies showed that the formation ages of chondrites (4.55–4.56 Ga) effectively equal the formation age of the solar system. Recently, researchers have undertaken U-Pb isotopic studies of phosphates separated from equilibrated ordinary chondrites, which are the major hosts for U and are enriched by an order of magnitude or more relative to the bulk rock (typical U concentrations of 0.1–3 ppm in phosphates). The observed Pb-Pb model ages for these phosphates range from 4.563–4.502 Ga, with an analytical precision of 1 Ma and the U-Pb system is apparently concordant. They also argued that the Pb-Pb ages of the phosphates from several H chondrites show a negative correlation with metamorphic grade. They concluded that thermal processing of the equilibrated chondrites took place over a 60 Ma interval and grain size of the phosphates increases with the degree of metamorphism. In the Leoncin meteorite, apatite reveal the 207Pb/206Pb age, which is 4549±61 Ma. The obtained apatite age in the Leoncin meteorite reflects the early solar system formation process. Moreover, the age is an example of the early solar system metamorphism, which confirms a slightly younger event of secondary changes of the parent body for this meteorite. It is also the first isotopic age of a Polish meteorite.

Opis:: Zawartość fosforu w węglu jest bardzo ważnym parametrem jakości węgli stosowanych jako składniki mieszanek wsadowych przy produkcji koksu. Fosfor jest niepożądanym składnikiem zwłaszcza węgli koksowych, ponieważ podczas koksowania 98% fosforu przechodzi do koksu, a następnie w procesie wielkopiecowym do stali, powodując jej kruchość. W związku z tym jedyną możliwością obniżenia poziomu fosforu w mieszankach wsadowych jest dobór składników o niskiej zawartości tego pierwiastka. Istnieje wiele metod analitycznych wykorzystywanych do analizy zawartości fosforu w paliwach stałych. W pracy podjęto próbę porównania metody miareczkowej i metody spektrometrii emisyjnej. Na podstawie uzyskanych wyników opracowano charakterystykę obu metod badawczych, obejmującą takie parametry statystyczne jak powtarzalność i odtwarzalność metody, granice oznaczalności, niepewności rozszerzone wyniku pomiaru oraz współczynnik zmienności dla metody miareczkowej i spektrometrycznej. W celu określenia dokładności metod, porównano uzyskane wyniki analiz z wartościami certyfikowanymi.
The phosphorus content of the coal is a very important parameter used to evaluate the quality of coal utilized as a component of blends in the production of coke batch. Phosphorus is an undesirable component, particularly, of coking coals because during coking 98% of the phosphorus enters the coke, and then, in the blast furnace process, the steel making it fragile. Therefore, the only way to reduce the level of phosphorus in the compound is the selection of a batch of components having a low content of this element. There are many analytical methods used for the analysis of phosphorus in solid fuels. This paper attempts to compare titration and emission spectrometry methods. The obtained results allowed to develop characteristics of both research methods, including statistical parameters such as repeatability and reproducibility of the method, the limit of quantification, extended uncertainties of the measurement result as well as the coefficient of variation for titration and spectrometric methods. In order to determine the accuracy of the methods the obtained results of analyses were compared with the certified values.

Opis:: The magnetron sputtering technology has been applied to obtain five kinds of thin, nickel-rich layers on tungsten powder substrate. Circular plates (30 mm in diameter) of pure nickel (99.9%), inconel 600 (72% Ni, 17% Cr, 10% Fe), inconel 601 (63% Ni, 25% Cr, 7.6% Fe), inconel c-276 (51% Ni, 16.5% Cr, 17% Mo) and incoloy H / HT (35% Ni, 23% Cr, 39.5% Fe) were used as sputtering targets. The nickel-based layers have been deposited on pure tungsten powder (2 g; fraction 20-50 µm). After 2 hours of sputtering, the produced layers have been dissolved in 2M HCl solution. The obtained solutions were then analyzed on Ni2+, Cr3+, Fe2+ or Mo2+ ions. The analysis data allows for evaluation of the thickness of the obtained coatings.

Opis:: The article presents the results of preliminary tests obtained from the analysis of ash coming from the combustion of various types of waste in household furnaces. The aim of this work was to examine the influence of various types of waste burned in household furnaces on the elemental composition of the generated ash. As part of the research, analyses of ash generated from the incineration of mixed waste, plastics, wood, textiles, rubber waste and paper were made. The content of selected metal ions: Mn, Cu, Mo, Zn, Cd, Tl, Cr, Co, Ni, As, Sn, Sb, Pb, V was determined in the tested samples, according to PN-EN ISO 17294-2: 2016-11 standard. The highest concentrations of zinc were found in the large-sized waste, rubber and textile ash samples and highest concentrations of copper were found in the plastic and paper ash samples. The highest concentrations for elements such as copper, lead, cobalt and chromium were recorded for samples of rubber and large-sized waste containing e.g. varnished furniture boards. The obtained results showed that depending on the waste incinerated, the content of selected metals was significantly different, and the highest concentrations were noted for samples of large-sized waste, waste from segregated plastics and waste from rubbers.
