Range Image Technique for Change Analysis of Rock Slopes Using Dense Point Cloud Data

The use of a terrestrial laser scanner is examined to measure the changes of rock slopes subject to a wave attack test. Real scenarios are simulated in a water flume facility using a wave attack experiment representing a storm of 3000 waves. The stability of two rock slopes of different steepness was evaluated under the set conditions. For quantification of the changes of the slopes after the wave attack test, terrestrial laser scanning was used to acquire dense 3D point cloud data sampling for slope geometries before and after the wave attack experiment. After registration of the two scans, representing situations before and after the wave attack, the cloud-to-cloud distance was determined to identify areas in the slopes that were affected. Then, a range image technique was introduced to generate a raster image to facilitate a change analysis. Using these raster images, volume change was estimated as well. The results indicate that the area around the artificial coast line is most strongly affected by wave attacks. Another interesting phenomenon considers the change in transport direction of the rocks between the two slopes: from seaward transport for the steeper slope to landward transport for the milder slope. Using the range image technique, the work in this article shows that terrestrial laser scanning is an effective and feasible method for change analysis of long and narrow rock slopes.

Raman Spectroscopy for Pharmaceutical Quantitative Analysis by Low-Rank Estimation.

Raman spectroscopy has been widely used for quantitative analysis in biomedical and pharmaceutical applications. However, the signal-to-noise ratio (SNR) of Raman spectra is always poor due to weak Raman scattering. The noise in Raman spectral dataset will limit the accuracy of quantitative analysis. Because of high correlations in the spectral signatures, Raman spectra have the low-rank property, which can be used as a constraint to improve Raman spectral SNR. In this paper, a simple and feasible Raman spectroscopic analysis method by Low-Rank Estimation (LRE) is proposed. The Frank-Wolfe (FW) algorithm is applied in the LRE method to seek the optimal solution. The proposed method is used for the quantitative analysis of pharmaceutical mixtures. The accuracy and robustness of Partial Least Squares (PLS) and Support Vector Machine (SVM) chemometric models can be improved by the LRE method.

Land uplift induced by injection: a feasible method to evaluate the security of CO2 capture and sequestration projects

Technology of CO2 capture and sequestration (CCS) is one of the many solutions to reduce greenhouse gases and alleviate the current global warming, but its security is important and needs to be evaluated. A simulator which links TOUGHREACT and FLAC3D was used to simulate the process of coupled temperature-hydrologic-mechanics (THM) in CCS. A test on laboratory scale was set up and water was injected into compacted sand covered by low permeability clay to study the land uplift displacement. The results were used to verify the accuracy of the simulator for calculating the THM coupling. The effects of injection quantity, injection time, and injection mode on land uplift were also studied on the constructed model. At last, a land uplift evaluation system was built to quantify the CO2 escape if any. The evaluation process can be divided into five steps: model generalization, acquisition of model parameters, numerical modeling, simulation and analysis, monitor comparison, and evaluation of model results. The major output of this study will provide a feasible method for quantitative analysis of CO2 leakage in CCS projects.

End Track Following Control Method for Multi-axis Machining of Linear Cutting Tools

In the process of linear tool multi-axis machining, it is prone to local interference, resulting in poor curvature matching of the machining end trajectory, tool path tracking control performance is not good, based on critical tool axis vector decomposition, a linear tool end path following control method for multi-axis machining is proposed. The tool axis spatial distribution model of complex curved surface channel parts is constructed, and the local interference suppression is carried out by using two-dimensional feasible pendulum tool domain analysis method. The curve and surface are the critical elements on the multi-axis machining interference surface of linear cutter. The intersection curve equation between the pendulum cutter plane and the surface to be processed is constructed, and the optimal tool parameter selection is realized by using the discrete characteristic point distribution of the surface of the critical cutter axis. Combined with the critical tool axis vector decomposition method, the end trajectory following control of linear tool multiaxial machining is realized. The simulation results show that the output stability of the end track following control of linear tool multiaxial machining is good by using this method. The precision and efficiency of multi-axis machining are improved significantly.

Quantitative analysis of peri-tumor fat in different molecular subtypes of breast cancer

Background and purposesThe aim of this study was to develop morphological analytic methods to analyze the tumor-fat interface and in different peritumoral shells away from the tumor, and to compare the results among three molecular subtypes of breast cancer. Materials and methodsA total of 102 women (mean age 48.5 y/o) with solitary well-defined breast cancers were analyzed, including 46 human epidermal growth factor receptor 2 (HER2) (+), 46 HER2(−) hormonal receptor (HR) (+), and 10 triple negative (TN) breast cancers. The tumor lesion, the breast, the fibroglandular and fatty tissue were segmented using well-established methods. The whole breast fat percentage and the peri-tumor interface fat percentage were measured. Three shells (SH1, SH2, SH3) surrounding the convex hall of the three dimensional (3D) tumor were defined and in each shell the volumetric percentage of fat was calculated. The peri-tumor interface fat percentage and the volumetric percentage of fat in the three peri-tumoral shells were compared among different subtypes. ResultsIn the TN group, the fat percentage on the tumor boundary was 43 ± 20% and 78 ± 12% for two dimensional (2D) and 3D measurement, respectively, which were the highest among the three subtypes but not significantly different. The fat percentage in SH2 and SH3 in the TN group was 82 ± 7% and 85 ± 7%, which was significantly higher compared to the two other two subtypes. The results remained after controlling for the whole breast fat percentage. ConclusionsThis study provided a feasible method for quantitative analysis of peri-tumoral tissue characteristics. Because of small patient number, the finding that TN tumors had the highest peri-tumor fat content among the three subtypes needs to be further verified with a large cohort study.

Economic Analysis of Power Plants Under Different Loads Based on Structural Theory

The economy analysis of coal-fired power plants is usually based on traditional thermal balance method, which only considers the thermodynamic factors but ignores the economic factors such as cost. In this paper, to have a more comprehensive and accurate evaluation on the production performance and economical efficiency of thermal systems, the cost analysis method based on the Structural Theory of Thermoeconomic is applied to a 300MW thermal power generating unit in Yunnan province. The thermoeconomic model and the exergetic cost model for the plant based on the Fuel—Product concept have been defined to quantify the productive interaction between different devices. By calculating the thermoeconomic cost of four typical different working conditions and analyzing the distributions and change rules of generating cost, the Structural Theory of Thermoeconomic is proved scientific and useful and offers a set of feasible and reliable analysis method for the performance analyses and improvement of power plants.

Integrated energy performance optimization of a passively designed high-rise residential building in different climatic zones of China

This paper mainly focuses on investigating the influence of weather conditions on the sensitivity analysis and optimization of a typical passively designed high-rise residential building. A holistic passive design approach combining a variance-based factor prioritizing and surrogate model based multi-objective optimization was previously proposed to explore the green building solution in the hot and humid climate of Hong Kong. The design approach is further extended for application into a broader spectrum of climates across the mainland of China, including the severe cold zone, cold zone, hot summer cold winter zone, temperate zone as well as hot summer warm winter zone. The relative weight analysis is first compared with the Fourier Amplitude Transformation Analysis (FAST) in prioritizing the weighting of design inputs for different climatic zones. The relative weight analysis is then proved a feasible alternative sensitivity analysis method when its corresponding multiple linear regression (MLR) model can achieve good prediction performance. Furthermore, a tuning program in R is developed to improve the prediction performance of surrogate models with the Support Vector Machine (SVM) algorithm under above climatic zones. The model fitting performance with SVM is proved to be greatly improved by modifying the Sigma and C parameters. Finally, optimum design options under the five climatic zones are discussed in relation to the outdoor thermal, ventilation and solar radiation conditions. This research explored the applicability of the proposed passive design optimization approach in diverse climates, and can therefore prompt decision-makers’ endorsement as a national green building design tool in the early planning stage.

CHANGE ANALYSIS OF LASER SCANS OF LABORATORY ROCK SLOPES SUBJECT TO WAVE ATTACK TESTING

Abstract. For better understanding how coastal structures with gentle slopes behave during high energy events, a wave attack experiment representing a storm of 3000 waves was performed in a flume facility. Two setups with different steepness of slope were compared under the same conditions. In order to quantify changes in the rock slopes after the wave attack, a terrestrial laser scanner was used to obtain 3D coordinates of the rock surface before and after each experiment. Next, through a series of processing steps, the point clouds were converted to a suitable 2D raster for change analysis. This allowed to estimate detailed and quantitative change information. The results indicate that the area around the artificial coast line, defined as the intersection between sloped surface and wave surface, is most strongly affected by wave attacks. As the distances from the sloped surface to the waves are shorter, changes for the mildly sloped surface, slope 1 (1 : 10), are distributed over a larger area compared to the changes for the more steeply sloped surface, slope 2 (1 : 5). The results of this experiment show that terrestrial laser scanning is an effective and feasible method for change analysis of rock slopes in a laboratory setting. Most striking results from a process point of view is that the transport direction of the rocks change between the two different slopes: from seaward transport for the steeper slope to landward transport for the milder slope.

Back Analysis and Application of Confined Aquifer Hydrogeological Parameters Based on Pumping Test

Hydrogeological parameters are important factors for engineering dewatering design. There is often a big difference in calculated hydrological parameters value due to the complexity and diversity of calculation of hydrogeological itself. In order to offset the disadvantage of low search efficiency and large amount of calculation by the traditional back analysis methods in geotechnical engineering, the back analysis method combining the Nelder–Mead algorithm and finite element method is studied. The back analysis code is developed by the software MATLAB, in which the finite element code of ABAQUS is embedded as a module. Using the proposed method in this paper, the hydrogeological parameters of the confined aquifer were calculated and compared with the theoretical analytic solution according to unsteady pumping test data. The results show that the parameter searching efficiency and the convergence precision of the proposed method have an obvious improvement and the inverse results meeting accuracy requirements can be obtained with less iterations. And results of theoretical method and numerical back analysis method are basically in the same order of magnitude, but the inverse result is smaller than the theoretical. The method proposed in this paper is effective. The proposed method is a feasible method for back analysis of stress, seepage and displacement in geotechnical engineering.

Micellar liquid chromatographic method for the determination of ephedrine and pseudoephedrine in human serum by direct inject of the sample with simple dilution

ABSTRACTA micellar high-performance liquid chromatographic method was developed to simultaneously determine ephedrine and pseudoephedrine in human serum. The serum sample pretreatment was a simple dilution in a micellar solution, filtration, and direct injection, thus avoiding time-consuming and tedious steps. Hence, there is no need to use an internal standard. The serum samples were analyzed using a mobile phase containing 1.50 × 10−1 mol/L sodium dodecyl sulfate and 0.02 mol/L sodium dihydrogen phosphate with 7.5% (v/v) 1-propanol at pH 3.0, running at 1.0 mL/min by an Inertsil C18 (150 × 4.6 mm, 5 µm) column at 30°C. The UV wavelength was set at 210 nm. The developed method was validated by linearity (r > 0.9990) and intra- and inter-day precisions of ephedrine and pseudoephedrine (relative standard deviation; RSD%, 0.04–10.40, and RSD %, 0.30–10.25, respectively), LODs for ephedrine and for pseudoephedrine was 2.63 and 2.70 µg/mL, respectively; lower limit of quantification for ephedrine and for pseudoephedrine was 4.38 and 4.51 µg/mL, respectively. Finally, the proposed method was applied to investigate ephedrine and pseudoephedrine in real human serum samples after oral administration of Kechuanning Koufye including Ephedra herb. It is environmentally friendly, easy-to-handle, and feasible method for routine analysis in clinical laboratory.

Fast Genome-Wide Third-order SNP Interaction Tests with Information Gain on a Low-cost Heterogeneous Parallel FPGA-GPU Computing Architecture

Complex diseases may result from many genetic variants interacting with each other. For this reason, genome-wide interaction studies (GWIS) are currently performed to detect pairwise SNP interactions. While the computations required here can be completed within reasonable time, it has been inconvenient yet to detect third-order SNP interactions for large-scale datasets due to the cubic complexity of the problem.In this paper we introduce a feasible method for third-order GWIS analysis of genotyping data on a low-cost heterogeneous computing system that combines a Virtex-7 FPGA and a GeForce GTX 780 Ti GPU, with speedups between 70 and 90 against a CPU-only approach and a speedup of approx. 5 against a GPU-only approach. To estimate effect sizes of third-order interactions we employed information gain (IG), a measure that has been applied on a genome-wide scale only for pairwise interactions in the literature yet.

Robustness Analysis of License Plate Visual Positioning Method in Vehicle Collision Warning System

Vehicle anti-collision warning system is a key research area of vehicle safety. It is also a necessary means to enhance driving safety and reduce traffic accidents. The visual location method is presented for this system based on license plate image. This method realizes visual positioning with the help of the mounting points of license plate. At the same time, the feasible robust analysis method is proposed for the visual positioning method with license plate frame image. Finally, the robust analysis determines good angles for commutating rotation parameter in the method of license plate image visual positioning. At the same time, it determines good angles for translation parameter and for rotation and translation transform. Therefore, robust analysis determines positions where the visual positioning method has high positioning accuracy. Robust analysis for license plate vision positioning method is useful in analysis of high positioning accuracy positions for the proposed license plate image visual location method combined with plate mounting points. The research content of this paper is beneficial to driver decision-making and improves the safety of collision warning system and intelligent vehicle.

Dynamic Traffic Congestion Simulation and Dissipation Control Based on Traffic Flow Theory Model and Neural Network Data Calibration Algorithm

Traffic congestion is a common problem in many countries, especially in big cities. At present, China’s urban road traffic accidents occur frequently, the occurrence frequency is high, the accident causes traffic congestion, and accidents cause traffic congestion and vice versa. The occurrence of traffic accidents usually leads to the reduction of road traffic capacity and the formation of traffic bottlenecks, causing the traffic congestion. In this paper, the formation and propagation of traffic congestion are simulated by using the improved medium traffic model, and the control strategy of congestion dissipation is studied. From the point of view of quantitative traffic congestion, the paper provides the fact that the simulation platform of urban traffic integration is constructed, and a feasible data analysis, learning, and parameter calibration method based on RBF neural network is proposed, which is used to determine the corresponding decision support system. The simulation results prove that the control strategy proposed in this paper is effective and feasible. According to the temporal and spatial evolution of the paper, we can see that the network has been improved on the whole.

Socioeconomic and religious differentials in marital fertility during the fertility transition: A micro-level study from Western Hungary, 1850–1939

The analysis of fertility decline and its socioeconomic and cultural determinants during the demographic transition is a topic that is rarely researched in Hungary. So far, the question has been examined only at country and regional levels, with the help of aggregate data. Much like the international research on historical demography, little attention has been paid to non-aggregate data and to the micro level. Previous family reconstitution studies, which can be regarded as the most feasible and prevalent method for micro-level analysis in Hungary, focused only on the analysis of pre-transitional fertility. We know, however, that on the one hand, in many communities irreversible fertility decline did not start before World War I, and on the other hand, the analysis of the transitional period offers more opportunities to better understand the background of changing fertility behaviour. The aim of the present paper is to investigate the socioeconomic and denominational differentials in marital fertility in a rapidly industrializing Western Transdanubian community, which was heterogeneous in these respects. The analysis covers the pre-transitional period and the fertility transition, mainly from the second part of the 19th century up to World War II. This period of the Hungarian demographic transition has never been examined at micro level. According to the results, the upper groups of the local society had higher fertility compared to others prior to the transition, but the socioeconomic patterns of childbearing changed during the 1870s–1880s. First, local elite groups began to decrease their family size. They were followed later by local craftsmen and skilled workers, then by smallholders, and finally by semi-skilled and unskilled workers. The fertility of Lutherans was slightly lower than that of Roman Catholics, but this can be explained by the different demographic and socioeconomic composition of these denominational groups. Fertility transition on the spot meant not only parity-specific birth control, but also increasing birth intervals, which was particularly significant in the period of the Great Depression (1929–1933).

A novel feasibility analysis method for black‐box processes using a radial basis function adaptive sampling approach

Feasibility analysis is used to determine the feasible region of a multivariate process. This can be difficult when the process models include black‐box constraints or the simulation is computationally expensive. To address such difficulties, surrogate models can be built as an inexpensive approximation to the original model and help identify the feasible region. An adaptive sampling method is used to efficiently sample new points toward feasible region boundaries and regions where prediction uncertainty is high. In this article, cubic Radial Basis Function (RBF) is used as the surrogate model. An error indicator for cubic RBF is proposed to indicate the prediction uncertainty and is used in adaptive sampling. In all case studies, the proposed RBF‐based method shows better performance than a previously published Kriging‐based method. © 2016 American Institute of Chemical Engineers AIChE J, 63: 532–550, 2017
