The Measurement Method for the Size of the Hole on the Part Surface Based on Grating Image Processing

With the development of manufacturing industry, the high precision size measurement for the holes on the surface of mechanical parts is required. A method for measuring size of the hole based on double projection is proposed in this paper. The CCD camera separately collects grating images which projected onto the part surface in two directions. The phase-shift method is used to calculate the phase of grating images in two directions, and the reconstructed three-dimensional shapes in the two directions are merged to measure the hole dimension. Experiment results show that the measurement accuracy of the thickness is 0.04mm, and the hole size can reach to 0.1 mm.

Supernova neutrino detection in XENONnT neutron and muon Vetoes

The current phase of the XENON Dark Matter Project, named XENONnT, will be operative in 2020 in the underground Laboratori Nazionali del Gran Sasso (LNGS). It is a multi-ton detector for direct search of Dark Matter, consisting of a double phase liquid-gas xenon Time Projection Chamber (TPC) which contains 5.9 tons of liquid xenon target mass, inserted in a cryostat surrounded by a tank containing 700 tons of water doped with Gd sulphate. Its aim, as that of its precursor XENON1T, is to detect elastic scattering of Weakly Interacting Massive Particles (WIMPs) off xenon nuclei. The presence of two Veto sub-systems, the muon Veto instrumented with 84 photomultiplier tubes (PMTs) and the neutron Veto with other 120 PMTs, allows to reduce the background for WIMPs search through muon and neutron tagging, while the presence of Gd sulphate increases the neutron capture cross section. Thanks to the large xenon target used and the presence of the two Vetoes, XENONnT will be able also to detect all flavours of Supernova neutrinos. Here the results from Monte Carlo simulations of XENONnT detection efficiency are presented for Supernova neutrinos through their inverse beta decay interactions in water of the two Veto sub-systems.

Integrable boundary conditions for the B2 model**Supported by the National Program for Basic Research of MOST (Grant Nos. 2016YFA0300600 and 2016YFA0302104), the National Natural Science Foundation of China (Grant Nos. 11934015, 11975183,11547045, 11774397, 11775178, 11775177 and 91536115), Australian Research Council (Grant No. DP 190101529), the Major Basic Research Program of Natural Science of Shaanxi Province (Grant Nos. 2017KCT-12, 2017ZDJC-32), and

New integrable B2 model with off-diagonal boundary reflections is proposed. The general solutions of the reflection matrix for the B2 model are obtained by using the fusion technique. We find that the reflection matrix has 7 free boundary parameters, which are used to describe the degree of freedom of boundary couplings, without breaking the integrability of the system. The new quantization conditions will induce the novel structure of the energy spectrum and the boundary states. The corresponding boundary effects can be studied based on the results in this paper. Meanwhile, the reflection matrix of high rank models associated with Bn algebra can also be obtained by using the method suggested in this paper.

Isomorphism, Diversification, and Strategic Ambiguity: Goal Setting of Chinese Higher Education Institutions in the Double World-Class Project

China has launched several national academic excellence initiatives since the 1990s, aimed at creating world-class universities. These projects contributed to the achievements of Chinese universities over the past decades and deeply influenced the field of Chinese higher education. This study focuses on the most recent Double World-Class (DWC) project and assesses the impacts of this project on the diversification of leading Chinese universities. Drawing on institutional organization theories, we analyzed how institutions set their goals for the DWC project in development plans. Findings demonstrate that on the one hand, the DWC project reinforced universities’ resource dependence on the government, which lead to universities adopting similar structures and practices. On the other hand, facing the intensified competition with domestic peers for the limited slots in the DWC project, Chinese universities differentiated their goals and orientations as they seek to highlight their competitive advantages. Findings highlight both the benefits and challenges brought by the strong nation-state policies in the pursuit of world-class universities.

Radical imagination and “otherwise possibilities” in qualitative research

This humanscript is an attempt to extend the limits of our qualitative research, theorizing and praxis alongside youth engaged in social justice projects. Research must bend, shift, and transform to the needs and will of communities–especially youth–whose voices in research are often maligned or misrepresented, if heard at all. Imagination and creativity are pathways to “otherwise” possibilities or alternative approaches to qualitative research theories, methodologies, and methods. This article offers three vignettes drawn from research projects with youth of color wherein three key commitments emerge: Double Dutch methodology, desire-based frameworks and projects in humanization, storying and listening. These are commitments to doing qualitative research with youth in more humanizing and creative ways.

Visual Speech Recognition for Daily Indonesian Words Based on Combination of Double Difference and Image Projection Method

In visual speech recognition, there are two approaches to lip feature extraction, which are based on appearance and shape. The appearance-based approach is usually better, because it provides visual features that not only include lip structure but also the visibility of the teeth and tongue. However, the disadvantage of this approach is that it produces too many features. Integration of double difference and horizontal-vertical image projection, is part of the appearance approach, in addition to using image projection as dimensional reduction. In previous study, the method has succeeded in recognizing 5 daily indonesian words, with data in form of videos recorded inside the room. In this study, we used the same words with 5 additional new words recorded outside the room. MLP (Multi Layer Perceptron) and SVM (Support Vector Machine) are used as classifiers. The word recognition process is evaluated using 10-fold cross validation. The method tested reached 88.92% on classification accuracy and 0.9948 on AUC (Area Under ROC Curve).

1919 in dynamic East Asia: March First and May Fourth as a starting point for revolution

The March First Movement and the May Fourth Movement are like mirrors reflecting each other’s relationship. This article uses the concept of “simultaneity” in global history to reevaluate the significance of both events in world history. It also examines the differences exhibited by the simultaneity of the two events from the perspective of an “interconnected East Asia.” After entering the world-system, imperial Japan, semi-colonial China, and colonial Korea occupied different positions within its hierarchical structure. Here we need to pay attention to the status-diverse but mutually influential conditions in East Asia. To see through the complexity of (semi)colonial modernity and find the inherent opportunities to overcome modernity, it is useful to analyze the “double project” of adapting to modernity and overcoming modernity. Since the 1920s, the two events have been continually reinterpreted in the vein of socio-historical changes. The question of how to remember the two is not only a historical question but also a practical question for the present. Now is truly the methodological turning point in exploring and reinterpreting the two events. The author will use the terms “March First Revolution” and “May Fourth Revolution” in an attempt to tackle this issue. The mass gatherings that took place during March First and May Fourth provide sufficient evidence to support the use of “revolution” to describe them. Although March First and May Fourth are part of two respective histories of Korea and China, at the same time they are part of East Asia’s and the world’s interconnected history.

Alternative continuous- and discrete-time neural networks for image restoration

ABSTRACTThis paper presents alternative continuous- and discrete-time neural networks for image restoration in real time by introducing new vectors and transforming its optimization conditions into a system of double projection equations. The proposed neural networks are shown to be stable in the sense of Lyapunov and convergent for any starting point. Compared with the existing neural networks for image restoration, the proposed models have the least neurons, a one-layer structure and the faster convergence, and is suitable to parallel implementation. The validity and transient behaviour of the proposed neural network is demonstrated by numerical examples.

‘하나님의 케노시스’(divine kenōsis)의 신학적 문제점과 대안으로서의 ‘하나님의 맞추심’(divine accommodation)

The aim of this study is to point out the theological problems of ‘divine kenōsis’ which expands kenōsis into an intrinsic attribute of God, and then to suggest Calvin’s ‘divine accommodation’ as an alternative notion to overcome it. The concept of ‘divine kenōsis’ that appeared in the violent and barbarous age of the twentieth century began to deconstruct the traditional and classical notion of God who is absolute, unchangeable, and impassible, and to create new divine image in which God is emptying Himself.BR This study analyzes the theological problems of ‘divine kenōsis’ into three points. First, ‘divine kenōsis’ can be misused as a dominant ideology to justify and legitimize the marginalized people’s suffering, by creating the image of the suffering God. A divine image better suited for people suffering is the omnipotent God who nurtures, sustains, and empowers all creatures, rather than the self-emptying God who suffers with them. Second, the concept of ‘divine kenōsis’ is raised on an assumption that God and creatures are in an incompatible or competitive relations. So, this concept shears God down to human size and makes God intrinsically powerless and vulnerable, by assuming that God operates in relation to creatures along the same line. Third, ‘divine kenōsis’ is the result of ‘double projections’; in other words, it is humanly constructed by both ‘primary projection’ that projects worldly attributes onto God and ‘reverse projection’ that re-projects the projected God’s attributes back onto the world. Therefore, it is just a product of an ‘idolatrous project.’BR ‘Divine accommodation’ suggested by John Calvin is an alternative notion to overcome the limitations of ‘divine kenōsis.’ This notion explains how God can accommodate to human, without declining His omnipotent divinity. In brief, ‘divine accommodation’ effectively remove tension between God’s omnipotence and His love, rejecting an image of the vulnerable God, a competing picture in which God and creature strive against each other in the same plane, and idolatrous anthropomorphic projections.

Evaluation of alternative conformal mapping for geospatial data in Jordan

AbstractMap projection is required to convert geodetic position of features on the earth’s surface onto a flat sheet to produce a map. Conformality is necessary for many large-scale maps to maintain angles and scale at any point in all directions. However, over extended area there is distortion due to the change of scale from one point to another. This research conducts a comparative analytical study of the recent established conformal projection, Transverse Mercator, in Hashemite Kingdom of Jordan with another proposed one. In fact, the suggested projection will be chosen to represent the area in single zone, balance errors in linear scale to minimize them especially in the capital and other major population centers, and to meet the requirements of modern surveying techniques. The main objective of this study is to apply possibility of Stereographic projection to find out the most suitable system for mapping in Jordan depending on the previous criteria and double projection approach by using ArcGIS system to define its optimum parameters.

Strong Superadditive Deficit of Coherence and Quantum Correlations Distribution**Supported by the National Natural Science Foundation of China under Grant Nos 11775177, 11775178, 11647057 and 11705146, the Special Research Funds of Shaanxi Province Department of Education under Grant No 16JK1759, the Basic Research Plan of Natural Science in Shaanxi Province under Grant No 2018JQ1014, the Major Basic Research Program of Natural

The definitions of strong superadditive deficit for relative entropy coherence and monogamy deficit of measurement-dependent global quantum discord are proposed. The equivalence between them is proved, which provides a useful criterion for the validity of the strong superadditive inequality of relative entropy coherence. In addition, the strong superadditive deficit of relative entropy coherence is proved to be greater than or equal to zero under the condition that bipartite measurement-dependent global quantum discord (GQD) does not increase under the discarding of subsystems. Using the Monte Carlo method, it is shown that both the strong superadditive inequality of relative entropy coherence and the monogamy inequality of measurement-dependent GQD are established under general circumstances. The bipartite measurement-dependent GQD does not increase under the discarding of subsystems. The multipartite situation is also discussed in detail.

Two Matrix-Type Projection Neural Networks for Matrix-Valued Optimization with Application to Image Restoration

In recent years, matrix-valued optimization algorithms have been studied to enhance the computational performance of vector-valued optimization algorithms. This paper presents two matrix-type projection neural networks, continuous-time and discrete-time ones, for solving matrix-valued optimization problems. The proposed continuous-time neural network may be viewed as a significant extension to the vector-type double projection neural network. More importantly, the proposed discrete-time projection neural network is suitable for parallel implementation in terms of matrix state spaces. Under pseudo-monotonicity and Lipschitz continuous conditions, the proposed two matrix-type projection neural networks are guaranteed to be globally convergent to the optimal solution. Finally, the proposed matrix-type projection neural network is effectively applied to image restoration. Computed examples show that the two proposed matrix-type projection neural networks are much superior to the vector-type projection neural networks in terms of computation speed.

A calibration transfer methodology for Standardization of Raman instruments with different spectral resolutions using Double Digital Projection Slit

A calibration transfer procedure is necessary when the established chemometric models are utilized to predict samples measured on different instruments. However, the existing methods are always ineffective for Raman instruments with different spectral resolution. We introduce a simple and reliable calibration transfer method based on Double Digital Projection Slit (DDPS), which can standardize the spectral resolution between different Raman instruments. The DDPS method is validated based on the pharmaceutical and liquid samples measured on two Raman instruments. The resolution of the primary instrument is about 3 times higher than the secondary instrument. Transfer is considered successful since the correlation coefficient (R) and root mean square error of prediction (RMSEP) are close to the corresponding primary prediction results. An attractive potential application of the DDPS method is to improve the prediction accuracy of an ordinary instrument by using the calibration model from a precise instrument with high resolution.

Application of Prefabricated Vertical Drain (PVD) for Basic Soil Stabilization in the Railway Double Track Construction Project at Km 437 + 300 to Km 438 + 500 Gombong, Kebumen

The subgrade in the railway double track development project in KM 437 + 300 to KM 438 + 500 Gombong, Kebumen is soft land (N-SPT <15) so that it requires efforts to improve the land to avoid land subsidence exceeding the allowable land subsidence, which is equal to 20cm In this research, an effort to repair subgrade uses Prefabricated Vertical Drain (PVD) to accelerate the process of soil congestion due to the load of the railroad pile, the burden of railroad construction, and the burden of the passing railroad. Compression analysis results show that the subgrade will experience a land subsidence of 0.524m. The natural consolidation time needed to achieve a 90% degree of consolidation is 268.9 years. Meanwhile, the time of consolidation to reach a degree of consolidation of 90% using PVD spaced 0.8 m with a triangle and quadrilateral pattern is for 15 weeks and 18 weeks. Planting PVD in both patterns is as deep as 24 m

Construction of Complete Orthogonal Genuine Multipartite Entanglement State**Supported by the National Natural Science Foundation of China under Grant Nos 11775177, 11775178, 11647057 and 11705146, the Special Research Funds of the Department of Education of Shaanxi Province under Grant No 16JK1759, the Basic Research Plan of Natural Science in Shaanxi Province under Grant No 2018JQ1014, the Major Basic Research Program of

With the development of quantum information processing, multipartite entanglement measures are needed in many cases. However, there are still no complete orthogonal genuine multipartite entanglement (GME) bases available as Bell states to bipartite systems. To achieve this goal, we find a method to construct complete orthogonal GME states, and we exclude many equivalent states by leveraging the group theory. We also provide the case of a 3-order 3-dimensional Hilbert space as an example and study the application of general results in the dense coding scheme as an application. Moreover, we discuss some open questions and believe that this work will enlighten extensive studies in this field.

Entropy of Schwarzschild-de Sitter Black Hole with Extra Term Correction**Supported by the National Natural Science Foundation of China under Grant Nos. 11675139, 11605137, 11435006, 11405130 and the Double First-Class University Construction Project of Northwest University.

The thermodynamical quantities are usually considered as the independent ones in the case of the existence of multi-horizons. Comparing the first laws for the event horizon and cosmological horizon of Schwarzschild-de Sitter space-time, we find them share the same values of mass, charge and cosmological constant, which might imply that there exists entanglement between the two horizons. Naturally we attempt to add an extra term, which contributed to the total entropy of the black hole. We recalculate the total entropy and the effective specific heat by taking the globally effective first law and find that they will be emanative when the two horizons approach to each other.

Improvement of fringe quality for phase extraction in double digital fringe projection

A procedure to improve the quality of the extracted phase by a passband filter within the spatial frequency domain is proposed, using the double-digital fringe projection method for obtaining the contour of the surface of different objects. This method requires the digital projection of two fringe patterns to the same object to generate an interference pattern containing moire fringes, which are related to the shape of the measured object. The proposed method pretends to remove remnant frequencies of the projected fringes keeping only the moire pattern.

A local projection for integrating geodetic and terrestrial coordinate systems

This paper develops a system for projecting coordinates from a geocentric coordinate system to a topocentric coordinate system defined by terrestrial measurements. The proposed system uses an extension of the Stereographic Double Map Projection and a parametric least squares estimation to calculate the parameters for the map projection. The Extended Stereographic Double Projection and the projection parameter estimation are implemented and tested. Tests are performed to determine rate that discrepancies occur and the maximum extents of the Extended Stereographic Double Projection. This maximum area is determined to be ∼10 km2 with RMS values of residuals of 0.0029 m in northing and 0.0020 m in easting. Tests are also performed to determine the factor that limits the effective area of the Projection.
