Vida quotidiana i marginalitat femenina a la València del segle XV
Authors: Peirats Navarro Anna Isabel 
Published: August 2021

Abstract
This article focuses on the description of the other view of Valencia in the 15th century, that of social marginalization, which, in addition to excluding a large part of society suffering from contagious diseases, could be manifested in a more concrete way for exercising various trades that are considered as immoral. The following pages offer a description of two female groups, particularly treated as vile and despicable: the healers, sorceresses and witches, whose strength was considered to have a demonic origin, and the prostitutes, dedicated to cover a “minor evil” in society, but seen as unworthy by society, because of the practical exercise of their trade.
As for the healers, both the sermons of St. Vincent and the texts of didactic and moralizing literature attack this profession, which, on the other hand, was required on many occasions. In this sense, Jaume Roig’s Spill presents a whole series of superstitious practices, exercised by women doctors. This natural inclination of women to superstition, understood as an exponent of popular culture, reaches its maximum expression from the idea, widespread in medieval Europe, that women become witches, renounce God and worship the devil.
Another group described in this article is that of prostitutes, whose profession is understood, from the Church Fathers, such as St. Augustine, and preachers such as St. Vincent, as a lesser evil, in order to avoid worse evils on the side of lust. Prostitutes, especially if they were muslims, were marginalized, punished, and considered vile women, because they had strayed from a honest life. The only possible alternative was to leave the brothel and be confined in a monastery, as is the case of the monastery of “Les Repenedides”, which was founded in Valencia in 1345, where prostitutes had to remain in prison for at least one year, in order to achieve social reintegration and grace before God.
Als marges de la història de l’art

Published: August 2021

Abstract
Bibliography on the pictorial production in the city and the kingdom of Valencia focuses on the altarpiece painting. Painters who embellished other devices – such as coffers, boxes, shields, flags, armours or curtains – have not been displaced from the history of Valencian painting, but they need to be considered on a case-by-case basis. This paper examines the painter of coffers’ profession between 1390 and 1430. For this purpose, we are going to consult archival documents published by Josep Sanchis Sivera and Lluís Cerveró Gomis in different journal volumes, as well as to look up information from the documentary collections on Valencian medieval painting edited by Ximo Company, Joan Aliaga, Lluïsa Tolosa, Milagros Cárcel Ortí and Juan Vicente García Marsilla. The aim is to read the documents in which the painters of coffers are mentioned – mainly inventories and judicial sentences or obligations – in order to suggest new questions about this medieval profession.
Metagovernance of migration policy in the Asia Pacific region: an analysis of policy tools
Authors: Fawcett Paul 
Published: August 2021

ABSTRACTThis article considers how nation states steer transnational forums by examining how the Australian government has ‘metagoverned’ the Bali Process on People Smuggling, Trafficking in Persons and Related Transnational Crime, a multilateral forum with 50 plus members (nation states and international agencies) that was created in 2002 to promote policy dialogue, information sharing and practical cooperation on irregular migration in the Asia Pacific region. A ‘tools-based approach’ is used to analyse the Australian government’s metagovernance of this forum across four dimensions: nodality; authority; treasure; organisation. The overall finding is that Australia has accumulated steering capacity across each of these dimensions and that a ‘tools-based approach’ to metagovernance offers a promising way of understanding differences in steering capacity within transnational forums.

Abstract

Purpose. The purpose of this work is to investigate the feasibility of TOPAS-nBio for track structure simulations using tuple scoring and ROOT/Python-based post-processing. Materials and methods. There are several example applications implemented in GEANT4-DNA demonstrating track structure simulations. These examples are not implemented by default in TOPAS-nBio. In this study, the tuple scorer was used to re-simulate these examples. The simulations contained investigations of different physics lists, calculation of energy-dependent range, stopping power, mean free path and W-value. Additionally, further applications of the TOPAS-nBio tool were investigated, focusing on physical interactions and deposited energies of electrons with initial energies in the range of 10–60 eV, not covered in the recently published GEANT4-DNA simulations. Low-energetic electrons are currently of great interest in the radiobiology research community due to their high effectiveness towards the induction of biological damage. Results. The quantities calculated with TOPAS-nBio show a good agreement with the simulations of GEANT4-DNA with deviations of 5% at maximum. Thus, we have presented a feasible way to implement the example applications included in GEANT4-DNA in TOPAS-nBio. With the extended simulations, an insight could be given, which further tracking information can be gained with the track structure code and how cross sections and physics models influence a particle’s fate. Conclusion. With our results, we could show the potentials of applying the tuple scorer in TOPAS-nBio Monte Carlo track structure simulations. Using this scorer, a large amount of information about the track structure can be accessed, which can be analyzed as preferred after the simulation.

Study on aerodynamic noise of axial flow fan in ship signal cabinet
Authors: Zhu Zenghui , Li Shu 
Published: August 2021

AbstractIn order to study the aerodynamic noise characteristics of axial flow fan in the ship signal cabinet, the aerodynamic noise theory analysis and experimental research were carried out. By comparing and analyzing the vibration and noise spectrum of cabinet, it was determined that the noise of cabinet mainly came from the aerodynamic noise of axial flow fan in the cooling unit of rotating cage. The noise control of cabinet was studied by using the optimal design of the fan installation structure and the application of sound-absorbing cotton. The results show that the noise of fan was discrete noise. The noise increased 2.91 dB(A) when the net was installed in the fan inlet, meanwhile, the energy ratio of high-frequency noise (6000 to 14000 Hz) increased significantly. The sound was sharp. The noise of fan became smaller with the decrease of speed. The peak frequencies of fan noise spectrum were the multiple frequency of fundamental frequency and shaft frequency at different speeds. The sound pressure level was the largest at the fundamental frequency. That is, the noise of fan came from its blades. The noise reduction was 4.24 dB(A) by applying the sound-absorbing cotton on the inner wall of cabinet. The effects of noise reduction were obvious in the 200 to 2000 Hz range. The research results can provide theoretical and experimental support for the optimal design of ship signal cabinet.

Abstract
The output power of wind power and photovoltaic is randomness and uncertainty, which brings severe challenges to power generation planning and scheduling of power system. The concentrating solar power (CSP) station with heat storage has the same scheduling as the traditional unit. Through reasonable scheduling of CSP stations, the uncertainty of wind power and photovoltaic power generation can be effectively suppressed, and new energy consumption can be promoted. This paper comprehensively considers the market power sales benefits, grid-connected environmental benefits and system operation and maintenance costs of the wind power-photovoltaic-CSP combined system, a dispatching model is established with the objective of optimizing the grid connected benefits of the combined system. Aiming at the shortcomings of particle swarm optimization (PSO) that is easy to be premature, an improved particle swarm optimization (IPSO) algorithm is formed by adding convergence factor and improving inertia weight to optimize the scheduling model. The results show that the grid connection benefit of the combined system increases by 237784yuan per day after adding CSP. The convergence speed of the IPSO used in this paper has been greatly improved.

Published: August 2021

Abstract
Substation plays an important role in the power system as the pivot of the power grid. With the continuous expansion of the power grid, the intelligent inspection system based on robots is widely used in the substation industry. However, the existing inspection robot has some drawbacks, such as low battery capacity, weak obstacle performance, slow movement speed, and blind areas during the inspection. This paper proposed some measurements aimed at these drawbacks, such as optimizing the robot performance, adding the image acquisition PTZ (Pan, Tilt, and Zoom camera) in fixed point, using the AR (Augmented Reality) glasses assistance. These approaches improve the efficiency and quality of the existing intelligent inspection system in the substation.

Published: August 2021

Abstract
As one of the important equipment to ensure the normal operation of substation, the performance of grounding grid has been highly concerned. In recent years, researchers propose that the theory of electromagnetic induction can be used to diagnose and identify the corrosion fault of substation grounding grid. In this paper, a fault classification model based on LS-SVM optimized by PSO is proposed to identify the corrosion fault of grounding grid. Firstly, the wavelet packet transform principle is used to filter the original data, and the wavelet packet energy is used to construct the fault eigenvalue as the input of the fault classification model. Based on LS-SVM, a corrosion fault classification model is constructed, and particle swarm optimization method is used to optimize the parameters of the model, which solves the problem of traditional SVM parameter optimization. Through the practical application in substation, the model proposed in this paper can identify the corrosion of grounding grid conductor without excavation and power failure, which provides an effective scheme for engineering application.

Published: August 2021

Abstract
Single-photon light detection and ranging system has been widely used in three-dimensional (3D) imaging for its advantages in weak echo detection and high resolution. However, long-range imaging is a great challenge due to the device performance limits and strong solar irradiance. In this paper, we experimentally demonstrate a single-photon imaging system with an operation wavelength of 1064 nm in daytime. An all-fiber optical system with a two-dimensional rotation platform is designed to realize a wide scanning. And a sub-pixel scanning method is used to improve spatial resolution. Image reconstruction is based on the iterative shrinkage-threshold algorithm; herein the noise threshold is self-adaptive to the received photon-counting distribution. Multi-range information can be retrieved from each pixel and 3D point cloud is finally generated. Results show that the range resolution is 38 cm and the spatial resolution is about 7.4 cm at the distance of 2.13km, three times of the diffraction limit of the optical system.

Published: August 2021

Abstract
Traditional cylinder head gasket design is based on the assumption that the mating surfaces’ form is ideal plane. However, high definition metrology (HDM) shows that the top surface of cylinder blocks and the bottom surface of cylinder heads are far from ideal plane and presents a macro form error. To compensate the macro form error of the mating surfaces, a gasket design optimization method is proposed in this paper. It mainly consists of two modules. The first module is surface alignment and gap calculation. Measured surface topography is aligned by control point registration and the control points are found by region labelling algorithm. The second module is gasket design optimization based on surface gap. A case study shows the details of the proposed gasket design optimization method.
