THE EXECUTION OF THE MULTILEVEL FAST MULTIPOLE ALGORITHM USING FOURIER ANALYSIS TO SOLVE PLANE WAVE SCATTERING FROM PERFECT ELECTRIC CONDUCTOR SURFACES

The multilevel fast multipole algorithm (MLFMA) is an algorithm employed to speed up the matrix-vector multiplication required to solve equations using an iterative method. In this algorithm, the Green's function is approximated by an expression that separates the receiver point from the source point. Each problem has a unique Green's function, which means derivations are required to get the approximation. As a result, although the algorithm is the same for all problems, each problem requires a new code. To solve these issues, the MLFMA is executed by approximating the Green's function using a Fourier series. The proposed approach is to finding the approximation is straightforward. In addition, the code will always be the same regardless of the problem. In this study, electromagnetic wave scattering from two- and three-dimensional perfect electric conductor surfaces was solved using the proposed approach, the conventional approach, and the method of moments. The results revealed that the suggested method is precise and faster compared to the method of moments and slightly slower than the MLFMA for a large number of unknowns.

Evaluation of a novel mobile phone application for blood pressure monitoring: a proof of concept study.

To provide information about the clinical relevance of blood pressure (BP) measurement differences betweena new smartphone application (OptiBP™) and the reference method (automated oscillometric technique) using a noninvasive brachial cuff in patients admitted to the emergency department. We simultaneously recorded three BP measurements using both the reference method and the novel OptiBP™(test method), except when the inter-arm difference was > 10mmHg BP. Each OptiBP™ measurement required 1-min and the subsequent reference method values were compared to the values obtained with OptiBP™ using a Bland-Altman analysis and error grid analysis. Among the 110 patients recruited, OptiBP™ BP values could be collected on 61 patients (55%) and were included in the statistical analysis. The mean of differences (95% limits of agreement) between the reference method andthe test method were - 0.1(- 22.5 to 22.4mmHg) forsystolic arterial pressure (SAP), - 0.1(- 12.9 to 12.7mmHg) fordiastolic arterial pressure (DAP)and - 0.3(- 18.1 to 17.4mmHg) formean arterial pressure (MAP).The proportions of measurements in risk zones A-E were 86.9%, 13.1%, 0%, 0%,and0% for MAPand89.3%, 10.7%, 0%, 0%,and0% for SAP. In this pilot study conducted in stable and awake patients admitted to the emergency department, the absolute agreement between the OptiBP™ and the reference method was moderate. However, when BP measurements were made immediately after an initial calibration, error grid analysis showed that 100% of measurement differences between the OptiBP™ and reference method were categorized as no- or low-risk treatment decisions for all patients.Trial Registration: ClinicalTrials.gov Identifier: NCT04121624.

Conceptual Metaphor «Human Being – Nature» In Literary Text: Pragmatics and Functions

The relevance of the study is determined by the anthropocentrism of the modern scientific paradigm of linguistics and the need to establish correlations of the constituents of linguistic consciousness and objects of the external world in the structuring and functioning of the conceptual metaphor in the literary text. Conceptual metaphor is a mental topological projection of interacting areas of linguistic consciousness and the surrounding world. The purpose of the article is to study the functional and pragmatic potential of metaphorical models built on the basis of the conceptual metaphor «Human Being – Nature» in a literary text. The material for the study was the literary texts of the novels of I.S. Turgenev’s “Rudin”, “Fathers and Sons”, “Smoke”, “Virgin Soil”, containing representative metaphorical micro and macro contexts. The complex of research methods includes the method of continuous sampling, deductive-inductive method, conceptual analysis, and the method of linguistic interpretation. The functions of metaphorical contexts, which are based on the conceptual metaphor Human - Nature, consist in the possibility of representing the inner world of characters, their general cultural potential, social status and origin; the use of metaphors in the speech of characters (external and internal) allows us to talk about the figurative perception of the world by these heroes, about the level of their emotionality and linguistic creativity, since metaphors are a kind of human thinking patterns. Analysis of the implementation of the conceptual metaphor «Human Being- Nature» in a literary text allows one to discover and describe the priority cognitive structures of the author’s linguistic consciousness and values inherent in the individual author’s picture of the world. Research prospects are in the possibility of identifying priority conceptual metaphors in the individual author’s picture of the world on the basis of literary texts in order to identify and describe the dominants of linguistic consciousness and the value picture of the world of a particular author

Quantification and evaluation of atmospheric pollutant emissions from open biomass burning with multiple methods: a case study for the Yangtze River Delta region, China

Abstract. Air pollutant emissions from open biomass burning (OBB) in the Yangtze River Delta (YRD) were estimated for 2005–2015 using three (traditional bottom-up, fire radiative power (FRP), and constraining) approaches, and the differences among those methods and their sources were analyzed. The species included PM10, PM2.5, organic carbon (OC), elemental carbon (EC), CH4, non-methane volatile organic compounds (NMVOCs), CO, CO2, NOx, SO2 and NH3. The interannual trends in emissions with FRP-based and constraining methods were similar to the fire counts in 2005–2012, while those with the traditional method were not. For most years, emissions of all species estimated with the constraining method were smaller than those with the traditional method except for NMVOCs, while they were larger than those with the FRP-based method except for EC, CH4 and NH3. Such discrepancies result mainly from different masses of crop residue burned in the field (CRBF) estimated in the three methods. Chemistry transport modeling (CTM) was applied using the three OBB inventories. The simulated PM10 concentrations with constrained emissions were closest to the available observations, implying that the constraining method provided the best emission estimates. CO emissions in the three methods were compared with other studies. Similar temporal variations were found for the constrained emissions, FRP-based emissions, GFASv1.0 and GFEDv4.1s, with the largest and the lowest emissions estimated for 2012 and 2006, respectively. The temporal variations in the emissions based on the traditional method, GFEDv3.0, and the method of Xia et al. (2016) were different. The constrained CO emissions in this study were commonly smaller than those based on the traditional bottom-up method and larger than those based on burned area or FRP in other studies. In particular, the constrained emissions were close to GFEDv4.1s that contained emissions from small fires. The contributions of OBB to two particulate pollution events in 2010 and 2012 were analyzed with the brute-force method. Attributed to varied OBB emissions and meteorology, the average contribution of OBB to PM10 concentrations in 8–14 June 2012 was estimated at 37.6 % (56.7 µg m−3), larger than that in 17–24 June 2010 at 21.8 % (24.0 µg m−3). Influences of diurnal curves of OBB emissions and meteorology on air pollution caused by OBB were evaluated by designing simulation scenarios, and the results suggested that air pollution caused by OBB would become heavier if the meteorological conditions were unfavorable and that more attention should be paid to the OBB control at night. Quantified with Monte Carlo simulation, the uncertainty of the traditional bottom-up inventory was smaller than that of the FRP-based one. The percentages of CRBF and emission factors were the main source of uncertainty for the two approaches. Further improvement on CTM for OBB events would help better constrain OBB emissions.

Predicting the soil water retention curve from the particle size distribution based on a pore space geometry containing slit-shaped spaces

Abstract. Traditional models employed to predict the soil water retention curve (SWRC) from the particle size distribution (PSD) always underestimate the water content in the dry range of the SWRC. Using the measured physical parameters of 48 soil samples from the UNSODA unsaturated soil hydraulic property database, these errors were proven to originate from an inaccurate estimation of the pore size distribution. A method was therefore proposed to improve the estimation of the water content at high suction heads using a pore model comprising a circle-shaped central pore connected to slit-shaped spaces. In this model, the pore volume fraction of the minimum pore diameter range and the corresponding water content were accordingly increased. The predicted SWRCs using the improved method reasonably approximated the measured SWRCs, which were more accurate than those obtained using the traditional method and the scaling approach in the dry range of the SWRC.

Dilatrometric sintering study and characterization of alumina-nickel composites

Alumina-nickel composite samples (with 0, 10 and 20 vol.% of Ni) are prepared via slip casting method. Nickel and aluminium oxide powders were used as precursors and diammonium hydrocitrate and citric acid were used as dispersants. The obtained materials were analysed by dilatometry, X-ray diffraction and SEM. The densities were measured by Archimedes method and the hardness and fracture toughness were determined by using Vickers hardness tester. Special attention was paid to the linear shrinkage and the effective coefficient of thermal expansion measurements. The shrinkage curves were obtained by dilatometry test in a heating mode. It was shown that the increased amount of Ni particles in Al2O3-Ni composite structure causes reduction of starting densification temperature, increasing temperature of maximum densification and decreasing total shrinkage of the sample during sintering.
