Systematic mapping of technologies for supporting choreographic composition

Technology has increasingly occupied other areas of sciences and humanities, including art and dance. Over the years, initiatives to use technological applications in artistic performances have been observed and this research is developed regarding this context and the challenge of using technology to support the artist’s imagined creations. The systematic mapping of the literature carried out is part of a broad search for studies that portray the interdisciplinarity of these two universes, aiming to find technologies that support the choreographic composition process, focusing on tools that work together with the choreographer’s activities. The methodology consisted of using search terms in research repositories, which initially returned 635 publications, which were filtered by inclusion and exclusion criteria, to undergo further analysis. Eighteen tools were identified and explored in which the main applicability was the simulation of movements through graphic animation. From the operating mode of these applications, the challenges of the existing relationship between technology and the creation of dance were discussed. This study only incorporates technologies that act as a support tool by sharing the compositional effort, which creates the opportunity for future investigations into other ways of using technology in dance creation. The main contribution of this paper is identifying and classifying the main integration strategies of technology and dance composition, as well as summarizing the data and discussing its implications, been the identification of the lack of involvement of artists (end users) in the early stages of the development process the most relevant finding.
Hydrodynamics of Young Supernova Remnants and the Implications for their Gamma-ray emission

Supernovae (SNe) are generally classified into Type I and Type II. Most SNe (~ 80%), including all the subtypes of Type II, and Type Ib/c, arise from the core-collapse of massive stars. During their lifetime, mass-loss from these stars considerably modifies the medium around the stars. When the stars explode as SNe, the resulting shock wave will expand in this wind-modified medium. In contrast, Type Ia SNe will expand in a relatively uniform medium, but the dynamics are different from those of core-collapse SNe. For young supernova remnants, the properties of the ejecta as well as the surrounding medium are important in determining the subsequent evolution of the SN shock wave, and the dynamics and kinematics of the remnant. This will influence the acceleration of particles at the SN shocks, and consequently affect the gamma-ray emission from the remnant. Herein we discuss the expected properties, especially the density structure, of the medium around various types and sub-types of SNe, as suggested by current stellar evolution models. Using analytic and semi-analytic models and numerical simulations, we investigate how these affect the kinematics of the SN shock waves, assess the impact this would have on the production of cosmic rays, and show how it influences the time-evolution of the hadronic gamma-ray emission from the remnant. In the case of SNRs evolving in a wind medium, the emission should reach a maximum early on, and thereafter decrease with time. For SNe in a constant density medium, the emission would be expected to increase with time upto the advent of the Sedov stage.
Speckle projection profilometry used for detecting magnetic circuit drop height of relay with high reflective surface

Abstract. Aiming at the problem of camera pixel saturation caused by the high reflective area on the metal surface of a relay, we adopt speckle projection profilometry to detect the magnetic circuit drop height of the relay. The main problem is solved through a detailed analysis of characteristics according to different speckle gray values, speckle sizes, and shapes to effectively distinguish the confusion between the speckle reflection spots and background light reflection spots. The enhanced normalized cross-correlation sub-pixel algorithm is used to get a dense matching pair of points of the right and left images, and three-dimensional reconstruction is based on the triangulation parallax principle. The random sampling consensus algorithm and European clustering algorithm are used to segment the point cloud to obtain the core and yoke iron planes and measure the distance between the two planes. We measured two standard blocks with height difference of 1 mm, and the error is within 2% by the proposed method. The correctness is verified through real-time measurement for a magnetic circuit drop height of the relay assembly line.
OPTIMAL MASS CONFIGURATIONS FOR LENSING HIGH-REDSHIFT GALAXIES

We investigate the gravitational lensing properties of lines of sight containing multiple cluster-scale halos, motivated by their ability to lens very high redshift (z ∼ 10) sources into detectability. We control for the total mass along the line of sight, isolating the effects of distributing the mass among multiple halos and of varying the physical properties of the halos. Our results show that multiple-halo lines of sight can increase the magnified source-plane region compared to the single cluster lenses typically targeted for lensing studies and thus are generally better fields for detecting very high redshift sources. The configurations that result in optimal lensing cross sections benefit from interactions between the lens potentials of the halos when they overlap somewhat on the sky, creating regions of high magnification in the source plane not present when the halos are considered individually. The effect of these interactions on the lensing cross section can even be comparable to changing the total mass of the lens from 1015 M☉ to 3 × 1015 M☉. The gain in lensing cross section increases as the mass is split into more halos, provided that the lens potentials are projected close enough to interact with each other. A nonzero projected halo angular separation, equal halo mass ratio, and high projected halo concentration are the best mass configurations, whereas projected halo ellipticity, halo triaxiality, and the relative orientations of the halos are less important. Such high-mass, multiple-halo lines of sight exist in the Sloan Digital Sky Survey.
Lived Experiences of Combat-Related Amputees: A Phenomenological Study

Abstract This phenomenological study examines the characteristics that contribute to the development of resiliency in veterans of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) who experienced combat-related amputations. The project comprised recorded semi-structured, in-depth interviews with 10 OIF and OEF veteran male amputees. We transcribed the interviews and analyzed the resulting data yielding six emergent themes: grief, will to live and fight, amputation adjustment issues, social support as a protective factor, coping skills, and posttraumatic growth. This study’s results contribute to the body of knowledge on resiliency, which may improve therapeutic interventions to help veterans overcome traumatic events, such as combat-related amputation.
Laminated bamboo lumber in compression perpendicular to the grain direction: Experimental investigation and the finite element analysis

ABSTRACT Localized damage may occur due to the fact that laminated bamboo lumber (LBL) has a lower compressive strength perpendicular to the grain direction than it does parallel to the grain. In this study, the transverse compressive performance of LBL under entire-surface compression and local-surface compression is investigated. Load–displacement curves, stress–strain relationship, detailed failure modes, and basic mechanical properties are obtained. The results show that despite the compressive strength and elastic modulus being nearly the same in the two transverse orientations, the failure patterns are distinct due to the layer structure. Ramberg-Osgood relation is utilized to fit the stress–strain curves. Proportional limit strength is determined indicating that specimens compressed locally have a greater load-bearing capability. Based on the finite element analysis and theoretical study, the mechanism of the enhancement in proportional limit strength is revealed. Equations for determining the bearing load of a specimen under local compression in the elastic stage are derived from the simulation data and logit model, considering the contact length and geometric size of the specimen. Additionally, parametric tests are conducted to determine the effect of bearing shape, bearing area, and loading mode on the stress distribution and bearing capacity.

Effects of dust on radiation transfer in the Martian atmosphere. II. Heating due to absorption of the visible solar radiation and importance of radiative effects of dust on the Martian meteorological phenomena.

The complex index of refraction of the Martian dust particles suspended in the atmosphere is estimated. Using this parameter, we solve the multiple scattering equations and investigate quantitatively heating of the Martian atmosphere due to absorption of the visible solar radiation. Our results show that the atmosphere is strongly heated up by absorption of solar radiation due to dust, and that the thermal structure of the Martian atmosphere would be almost determined by the balance between heating and cooling caused by radiative effects of dust. It is also pointed out that the thermal effects due to dust would induce strong thermal tide. Analyses of the Mariner 9 data indicate fairly good agreement with our results. A new general circulation model for Mars including the thermal effects of dust should be required at the moment.
Numerical method for hyperbolic conservation laws via forward backward SDEs

It is well known that for solutions of semi-linear parabolic PDEs, there are equivalent probabilistic interpretations, which yields the so called nonlinear Feymman-Kac formula. By adopting such formula, we consider in this work a novel numerical approach for solutions of hyperbolic conservation laws. Our numerical method consists in efficiently computing the viscosity solutions of conservation laws. However, instead of solving the viscosity problem directly (which is difficult), we find its equivalent probabilistic solution by adopting the Feymman-Kac formula, which relies on solving the equivalent forward backward stochastic differential equations. It is noticed that such framework possesses the following advantages: (i) the viscosity parameter can be chosen sufficiently small (say $10^{-10}$); (ii) the computational procedure on each discretized time level can be \textit{completely parallel}; (iii) the traditional CFL condition is dramatically weakened; (iv) one does not need to handle the transition layers and discertizations of derivatives. Thus, high accuracy viscosity solutions can be efficiently found. Several numerical examples are given to demonstrate the effectiveness of the proposed numerical method.
Do Education Investment and Welfare of Labor Affect Productivity Growth in Indonesia?

Increasing the education budget in Indonesia has become the focus of economic politics because it is a fundamental issue. Education, as a significant component of labor productivity, plays a vital role in driving the welfare of the workforce due to the increase in the Total Factor Productivity (TFP). This paper aims to test the quality of tertiary education by using World Bank and APO data. This paper provides an overview of tertiary education that influences TFP when juxtaposed with several other control variables and uses the ARDL (Autoregressive Distributed Lag) test. The results show that TFP growth is significantly positively affected by the improvement of tertiary education quality and production capital but is significantly affected by the welfare of the workforce. This study implies that the government must allocate an adequate budget to improve education quality in Indonesia.How to Cite:Aji, R. H. S. , Baharin, R. , Yussof, I. , & Mohd Saukani, M. N. (2022).

A parallel algorithm for nonlinear convection-diffusion equations

A parallel algorithm for the efficient solution of nonlinear time-dependent convection-diffusion equations with small parameter on the diffusion term is presented. The method is based on a physically motivated domain decomposition that is dictated by singular perturbation analysis. The analysis is used to determine regions where certain reduced equations may be solved in place of the full equation. The method is suitable for the solution of problems arising in the simulation of fluid dynamics. Experimental results for a nonlinear equation in two-dimensions are presented.
H∞ optimal and suboptimal controllers for infinite dimensional SISO plants

This paper presents a simple formula for H/sup /spl infin// optimal and suboptimal controllers for unstable SISO distributed plants, with rational weighting functions. The controller is expressed in terms of i) inner and outer parts of the plant, ii) a finite dimensional spectral factor obtained from the weighting functions, and iii) a rational function satisfying certain interpolation conditions. Under certain genericity assumptions, this rational function is of dimension less than or equal to n/sub 1/+l-1 (n/sub 1/+l in the suboptimal case), where l is the number of unstable poles of the plant and n/sub 1/ is the order of the sensitivity weighting function. There are 2(n/sub 1/+l) (2(n/sub 1/+l+1) in the suboptimal case) linear equations, which determine this rational function. These linear equations can be written directly from the structure of the controller. >
ASSESSMENT OF ENERGETIC NEUTRAL He ATOM INTENSITIES EXPECTED FROM THE IBEX RIBBON

Full sky maps of energetic neutral atoms (ENA) obtained with the Interstellar Boundary Explorer revealed a bright, arc-like Ribbon. We compare possible, though as yet undetected, He ENA emission in two models of the Ribbon origin. The models were originally developed for hydrogen ENA. In the first one, ENA are produced outside the heliopause from the ionized neutral solar wind in the direction where the local interstellar magnetic field is perpendicular to the line of sight. The second model proposes production at the contact layer between the Local Interstellar Cloud (LIC) and the Local Bubble (LB). The models are redesigned to helium using relevant interactions between atoms and ions. Resulting intensities are compared with possible emission of helium ENA from the heliosheath. In the first model, the expected intensity is ∼0.014 (cm2 s sr keV)−1, i.e., of the order of the He emission from the heliosheath, whereas in the second, the LIC/LB contact layer model, the intensity is ∼(2–7) (cm2 s sr keV)−1, i.e., a few hundred times larger. If the IBEX Ribbon needs a source population of He ENA leaving the heliosphere, it should not be visible in He ENA fluxes mainly because of the insufficient supply of the parent He ENA originating from the neutralized solar wind α-particles. We conclude that full-sky measurements of He ENA could give promising prospects for probing the Local Interstellar Medium at the distance of a few thousand AU and create the possibility of distinction between the above mentioned models of Ribbon origin.
Peer Influence in the Adoption of Video Games

The authors investigate how peer influence affects customers' product adoption behaviors in emerging video game platforms. Understanding peer influence is critical to motivating users' willingness to purchase and improving game publishers' marketing performance. While similarities between socially linked users can be viewed as a consequence of social influence, homophily may also contribute to such phenomenon, causing identification difficulties in observational studies. Using data from the world's largest digital distribution platform for video games, the authors leverage state-of-the-art recommender system algorithms and propose an innovative framework to identify social influence in the adoption of video games when a confounding homophily effect is present. The results show that peer influence has a positive impact on platform users' adoption behaviors (i.e., a user tends to adopt a video game that has been purchased by his peers). This study also finds that peer influence would have been overestimated if homophily was not properly controlled.
Geodesic Structure of the Noncommutative Schwarzschild Anti-de Sitter Black Hole I: Timelike Geodesics

By considering particles as smeared objects, we investigate the effects of space noncommutativity on the geodesic structure in Schwarzschild-AdS spacetime. By means of a detailed analysis of the corresponding effective potentials for particles, we find the possible motions which are allowed by the energy levels. Radial and non-radial trajectories are treated and the effects of space noncommutativity on the value of the precession of the perihelion are estimated. We show that the geodesic structure of this black hole presents new types of motion not allowed by the Schwarzschild spacetime.
FRESNEL OPERATOR, SQUEEZED STATE AND WIGNER FUNCTION FOR CALDIROLA KANAI HAMILTONIAN

Based on the technique of integration within an ordered product (IWOP) of operators, we introduce the Fresnel operator for converting a kind of time-dependent Hamiltonian into the standard harmonic oscillator Hamiltonian. The Fresnel operator with the parameters A, B, C, D corresponds to classical optical Fresnel transformation, these parameters are the solution to a set of coupled partial differential equations set up in the above-mentioned converting process. In this way, the Caldirola–Kanai Hamiltonian has been easily converted into the standard harmonic oscillator Hamiltonian. And then the exact wave function solution of the Schrodinger equation governed by the Caldirola–Kanai Hamiltonian is obtained, which represents a squeezed number state. The corresponding Wigner function is derived by virtue of the Weyl ordered form of the Wigner operator and the order-invariance of Weyl ordered operators under similar transformations.
Vorticity structure and evolution in a transverse jet

Transverse jets arise in many applications, including propulsion, effluent dispersion, oil field flows, and V/STOL aerodynamics. This study seeks a fundamental, mechanistic understanding of the structure and evolution of vorticity in the transverse jet. We develop a high-resolution three-dimensional vortex simulation of the transverse jet at large Reynolds number and consider jet-to-crossflow velocity ratios r ranging from 5 to 10. A new formulation of vorticity-flux boundary conditions accounts for the interaction of channel wall vorticity with the jet flow immediately around the orifice. We demonstrate that the nascent jet shear layer contains not only azimuthal vorticity generated in the jet pipe, but wall-normal and azimuthal perturbations resulting from the jet–crossflow interaction. This formulation also yields analytical expressions for vortex lines in the near field as a function of r. Transformation of the cylindrical shear layer emanating from the orifice begins with axial elongation of its lee side to form sections of counter-rotating vorticity aligned with the jet trajectory. Periodic roll-up of the shear layer accompanies this deformation, creating complementary vortex arcs on the lee and windward sides of the jet. Counter-rotating vorticity then drives lee-side roll-ups in the windward direction, along the normal to the jet trajectory. Azimuthal vortex arcs of alternating sign thus approach each other on the windward boundary of the jet. Accordingly, initially planar material rings on the shear layer fold completely and assume an interlocking structure that persists for several diameters above the jet exit. Though the near field of the jet is dominated by deformation and periodic roll-up of the shear layer, the resulting counter-rotating vorticity is a pronounced feature of the mean field; in turn, the mean counter-rotation exerts a substantial influence on the deformation of the shear layer. Following the pronounced bending of the trajectory into the crossflow, we observe a sudden breakdown of near-field vortical structures into a dense distribution of smaller scales. Spatial filtering of this region reveals the persistence of counter-rotating streamwise vorticity initiated in the near field.
Augmented reality and brain-computer interfaces for human-robot collaboration in manufacturing contexts

The most practical methods to allow manipulators to work together in the same workspace and collaborate with humans on the same tasks are brain-computer interfaces (BCIs) and augmented reality (AR). This paper provides a theoretical introduction to AR and BCI technologies in human-robot collaboration (HRC), fully demonstrating the practicability of AR-HRC and BCI-HRC solutions in manufacturing workspaces, including key advantages and future interests. Results show that these solutions have great potential to improve the current manufacture situation and impact the future research of HRC.
FrameRank: A Text Processing Approach to Video Summarization

Video summarization has been extensively studied in the past decades. However, user-generated video summarization is much less explored since there lack large-scale video datasets within which human-generated video summaries are unambiguously defined and annotated. Toward this end, we propose a user-generated video summarization dataset - UGSum52 - that consists of 52 videos (207 minutes). In constructing the dataset, because of the subjectivity of user-generated video summarization, we manually annotate 25 summaries for each video, which are in total 1300 summaries. To the best of our knowledge, it is currently the largest dataset for user-generated video summarization. Based on this dataset, we present FrameRank, an unsupervised video summarization method that employs a frame-to-frame level affinity graph to identify coherent and informative frames to summarize a video. We use the Kullback-Leibler(KL)-divergence-based graph to rank temporal segments according to the amount of semantic information contained in their frames. We illustrate the effectiveness of our method by applying it to three datasets SumMe, TVSum and UGSum52 and show it achieves state-of-the-art results.
Strong deflection gravitational lensing

In this work are reviewed several aspects of gravitational lensing produced by astrophysical bodies that strongly curve the spacetime in their vicinity. When an object with a photon sphere (e.g. a black hole) is interposed between a source and an observer, in addition to primary and secondary images due to small deflections of the light rays, there are two infinite sets of images called relativistic, produced by light passing close to the photon sphere, which undergoes a large deflection. The positions and magnifications of relativistic images can be obtained numerically or analytically, in the latter case by an approximate method called strong deflection limit. This method is applied to the study of lensing by non-rotating black holes and also by rotating ones. For the latter, is also of interest to study the deformation of the shadow cast by the black hole, which depends on the rotation parameter.
