Розглядаються методи використання нечіткої логіки для вирішення задач керування електромеханічними системами. Як засіб для підвищення якості функціонування автоматизованих електромеханічних систем використовується один з сучасних принципів автоматичного управління - адаптивне управління, що реалізується за допомогою інтелектуальних технологій формування адаптивних алгоритмів регулювання та управління, а саме технологій нечіткого управління (Fuzzy-control). Побудовано дві моделі систем управління: класична двоконтурна система стабілізації швидкості обертання двигун постійного струму - керований випрямляч з пропорційно-інтегральним регулятором і система стабілізації системи двигун постійного струму-керований випрямляч на основі нечіткого регулятора швидкості. Моделювання систем стабілізації і подальший аналіз перехідних процесів здійснювався за допомогою середовища моделювання Matlab Simulink. Після проведення необхідних математичних розрахунків і вибору найбільш оптимальних передавальних функцій, для кожного елемента була розроблена повна функціональна схема класичної двухконтурной системи стабілізації швидкості досліджуваної системи двигун постійного струму – керований випрямляч. Проводиться порівняльний аналіз основних показників якості перехідного процесу для класичної і нечіткої систем управління з метою виявлення переваг і недоліків останньої. Досліджуються дві системи керування: класична двоконтурна система стабілізації швидкості обертання з пропорційно-інтегральним регулятором і система стабілізації на основі нечіткого регулятора швидкості. Моделювання систем стабілізації і подальший аналіз перехідних процесів здійснюється у середовищі моделювання Matlab Simulink з використанням блоку інтелектуального керування Fuzzy Control Toolbox.

Tutkija ja tiede suomalaisessa yhteiskunnassa vuonna 2020
Authors: Poutanen Mikko J. , Juntunen Tapio , Lahtinen Mikko 
Published: April 2020

Pääkirjoituksen johtavana teemana on tieteen ja tutkijoiden asema vuoden 2020 alussa. Vuosina 2013, 2016 ja 2019 julkaistujen tiedebarometrien löydösten mukaan suomalaisten luotto tieteeseen on vankkaa. Kansalaisten tiedevastaisuudesta ei voi puhua, jos vuoden 2019 raportissa (Tiedebarometri 2019) seitsemän kymmenestä vastaajasta ilmoittaa seuraavansa tiedettä laajasti, niin luonnon, yhteiskunnan kuin taloudenkin osalta. On kuitenkin huomattava, että Tiedebarometri liikkuu abstraktilla tasolla: Vuoden 2019 raportin johdannossa todetaan, että ”tekstissä ei määritellä mitä tiede on tai mikä on tai ei ole tiedettä”. Näin ollen vastauksissa on tiettyä tulkinnallisuutta siitä, millainen mielikuva vastaajalla on ”tieteestä”. Tiedebarometrissa todettiin myös, että tiedepolitiikka kiinnosti vähiten, mikä saattaa vaikuttaa siihen, että tiedettä arvostavat tuntevat kuitenkin kovin vähän tieteen sisäisiä mekanismeja (Tiedebarometri 2019, 13).
Samaan aikaan avoimen tieteen julkaisukäytänteet tuovat tutkimustietoa entistä helpommin saataville. Avoimen tieteen (open access) laajempaa merkitystä suomenkielistä tutkimusta julkaisevien tieteellisten yhdistysten ja seurojen taloudelliselle kestävyydelle ei kuitenkaan ole ehditty tarkasti kartoittaa. Avoin julkaiseminen on ehdottomasti kannatettavaa, mutta sitä voidaan kehittää vain julkaisijoiden resurssien ja tieteellisten yhdistysten toimintalogiikan puitteissa. Kolmantena teemana pääkirjoituksessa käsitellään lyhyesti myös tiedolla johtamisen problematiikkaa.

Disk-integrated Thermal Properties of Ceres Measured at Millimeter Wavelengths

Published: April 2020

Abstract
We observed Ceres at three epochs in 2015 November and 2017 September and October with Atacama Large Millimeter/submillimeter Array (ALMA) 12 m array and in 2017 October with the ALMA Compact Array (ACA), all at ∼265 GHz continuum (wavelengths of ∼1.1 mm) to map the temperatures of Ceres over a full rotation at each epoch. We also used 2017 October ACA observations to search for HCN. The disk-averaged brightness temperature of Ceres is measured to be between 170 and 180 K during our 2017 observations. The rotational light curve of Ceres shows a double-peaked shape with an amplitude of about 4%. Our HCN search returns a negative result with an upper limit production rate of ∼2 × 1024 molecules s−1, assuming globally uniform production and a Haser model. A thermophysical model suggests that Ceres’s top layer has higher dielectric absorption than lunar-like materials at a wavelength of 1 mm. However, previous observations showed that the dielectric absorption of Ceres decreases toward longer wavelengths. Such distinct dielectric properties might be related to the hydrated phyllosilicate composition of Ceres and possibly abundant micrometer-sized grains on its surface. The thermal inertia of Ceres is constrained by our modeling as likely being between 40 and 160 thermal inertia units, much higher than previous measurements at infrared wavelengths. Modeling also suggests that Ceres’s light curve is likely dominated by spatial variations in its physical or compositional properties that cause changes in Ceres’s observed thermal properties and dielectric absorption as it rotates.
Nodal Precession in Closely Spaced Planet Pairs
Authors: Bailey Nora , Fabrycky Daniel 
Published: April 2020

Abstract
Planet–planet perturbations can cause planets’ orbital elements to change on secular timescales. Previous work has evaluated the nodal precession rate for planets in the limit of low α (semimajor axis ratio; 0 < α ≤ 1). Our simulations show that systems at high α (or low period ratio), similar to multiplanet systems found in the Kepler survey, have a nodal precession rate that is more strongly dependent on eccentricity and inclination. We present a complete expansion of the nodal precession rate to fourth order in the disturbing function and show that this analytical solution much better describes the simulated N-body behavior of high-α planet pairs; at α ≈ 0.5, the higher-order solution, on average, reduces the median analytical error by a factor of 7.5 from linear theory and 6.2 from a similar expansion assuming low α. We set limits on eccentricity and inclination where the theory is precisely validated by N-body integrations, which can be useful in future secular treatments of planetary systems.
Higher Radial Harmonics of Sausage Oscillations in Coronal Loops
Authors: Lim Daye , Nakariakov Valery M. , Yu Dae Jung , Cho Il-Hyun , Moon Yong-Jae 
Published: April 2020

Abstract
Impulsively excited sausage oscillations of a plasma cylinder with a smooth radial profile of Alfvén speed are analyzed with a numerical solution of the initial-value problem for a partial differential equation of the Klein–Gordon type, describing linear magnetoacoustic oscillations with a fixed axial wavelength and an azimuthal mode number. The range of analyzed ratios of Alfvén speeds outside and inside the cylinder is from 2 to 10. Both trapped and leaky regimes of the oscillations are considered. It is shown that even in the long-wavelength limit, i.e., for axial wavenumbers much smaller than the cutoff values, damping times of higher radial sausage harmonics could be significantly greater than the oscillation periods, i.e., several oscillation cycles could be present in the signal. The quality factors decrease with decfreasing ratios of Alfvén speeds outside and inside the cylinder. Oscillation periods of the second and third radial harmonics remain practically independent of the axial wavelength even when the wavelength is shorter than the radius of the cylinder. The ratios of oscillation periods of fundamental and higher radial and axial harmonics are found to be significantly different, up to a factor of two in the long-wavelength limit. It is concluded that higher radial harmonics could be responsible for the departure of observed sausage oscillation signals from a harmonic shape, especially during the first several cycles of the oscillation. Even in the absence of spatially resolved data, higher axial and radial harmonics can be distinguished from each other by the period ratios.

We investigate these quantities within a minimum model for the core of NSs consisting of neutrons, protons, electrons, and muons using an explicitly isospin-dependent parametric equation of state (EOS) constrained by available nuclear laboratory experiments and the latest astrophysical observations of NS masses, radii, and tidal deformabilities. We found that the absolutely maximum muon mass M

We found that the most important but uncertain nuclear physics ingredient for determining the muon contents in NSs is the high-density nuclear symmetry energy.
Transition from Ordered Pinched to Warped Magnetic Field on a 100 au Scale in the Class 0 Protostar B335

Abstract
We present our observational results of the 0.87 mm polarized dust emission in the Class 0 protostar B335 obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) at a 0.″2 (20 au) resolution. We compared our data at 0.87 mm with those at 1.3 mm from the ALMA archive. The observed polarization orientations at the two wavelengths are consistent within the uncertainty, and the polarization percentages are systematically higher at 1.3 mm than 0.87 mm by a factor of ∼1.7, suggesting that the polarized emission originates from magnetically aligned dust grains. We inferred the magnetic field orientations from the observed polarization orientations. We found that the magnetic field changes from ordered and highly pinched to more complicated and asymmetric structures within the inner 100 au scale of B335, and the magnetic field connects to the center along the equatorial plane as well as along the directions that are ∼40°–60° from the equatorial plane. We performed nonideal MHD simulations of collapsing dense cores. We found that similar magnetic field structures appear in our simulations of dense cores with the magnetic field and rotational axis slightly misaligned by 15° but not in those with the aligned magnetic field and rotational axis. Our results suggest that the midplane of the inner envelope within the inner 100 au scale of B335 could be warped because of the misaligned magnetic field and rotational axis, and the magnetic field could be dragged by the warped accretion flows.
A Deep Exposure in High Resolution X-Rays Reveals the Hottest Plasma in the ζ Puppis Wind

Abstract
We have obtained a very deep exposure (813 ks) of ζ Puppis (O4 supergiant) with the Chandra HETG Spectrometer. Here we report on analysis of the 1–9 Å region, especially well suited for Chandra, which has a significant contribution from continuum emission between well separated emission lines from high-ionization species. These data allow us to study the hottest plasma present through the continuum shape and emission line strengths. Assuming a power-law emission measure distribution that has a high-temperature cutoff, we find that the emission is consistent with a thermal spectrum having a maximum temperature of 12 MK as determined from the corresponding spectral cutoff. This implies an effective wind shock velocity of 900 km s−1, well below the wind terminal speed of 2250 km s−1. For X-ray emission that forms close to the star, the speed and X-ray flux are larger than can be easily reconciled with strictly self-excited line-deshadowing-instability models, suggesting a need for a fraction of the wind to be accelerated extremely rapidly right from the base. This is not so much a dynamical instability as a nonlinear response to changing boundary conditions.
Disk Structure around the Class I Protostar L1489 IRS Revealed by ALMA: A Warped-disk System

Abstract
We have observed the Class I protostar L1489 IRS with the Atacama Millimeter/submillimeter Array (ALMA) in Band 6. The C18O J = 2–1 line emission shows flattened and non-axisymmetric structures in the same direction as its velocity gradient due to rotation. We discovered that the C18O emission shows dips at a radius of ∼200–300 au while the 1.3 mm continuum emission extends smoothly up to r ∼ 400 au. At the radius of the C18O dips, the rotational axis of the outer portion appears to be tilted by ∼15° from that of the inner component. Both the inner and outer components with respect to the C18O dips exhibit the r
−0.5 Keplerian rotation profiles until r ∼ 600 au. These results not only indicate that a Keplerian disk extends up to ∼600 au but also that the disk is warped. We constructed a three-dimensional warped-disk model rotating at the Keplerian velocity, and demonstrated that the warped-disk model reproduces main observed features in the velocity channel maps and the PV diagrams. Such a warped-disk system can form by mass accretion from a misaligned envelope. We also discuss a possible disk evolution scenario based on comparisons of disk radii and masses between Class I and Class II sources.

Abstract
The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we combine a model of the galaxy–halo connection with newly derived observational selection functions based on searches for satellites in photometric surveys over nearly the entire high Galactic latitude sky. In particular, we use cosmological zoom-in simulations of MW-like halos that include realistic Large Magellanic Cloud (LMC) analogs to fit the position-dependent MW satellite luminosity function. We report decisive evidence for the statistical impact of the LMC on the MW satellite population due to an estimated 6 ± 2 observed LMC-associated satellites, consistent with the number of LMC satellites inferred from Gaia proper-motion measurements, confirming the predictions of cold dark matter models for the existence of satellites within satellite halos. Moreover, we infer that the LMC fell into the MW within the last 2 Gyr at high confidence. Based on our detailed full-sky modeling, we find that the faintest observed satellites inhabit halos with peak virial masses below

at 95% confidence, and we place the first robust constraints on the fraction of halos that host galaxies in this regime. We predict that the faintest detectable satellites occupy halos with peak virial masses above

, highlighting the potential for powerful galaxy formation and dark matter constraints from future dwarf galaxy searches.
Clinique des adolescents en souffrance de latence
Authors: Guinard Frédérik 
Published: April 2020

La clinique adolescente attire notre attention sur la raréfaction des mouvements d’exploration de son environnement et de sa vie psychique chez certains sujets inhibés ou ne tolérant pas la frustration. L’intérêt porté aux latences « en souffrance » renouvelle la compréhension de cette période du développement psychosexuel humain qui a longtemps été perçue/conçue comme « silencieuse » et d’envisager les leviers possibles de relance des processus transitionnels associés au travail de latence.
Franchir une frontière à l’adolescence
Authors: Chapellon Sébastien 
Published: April 2020

Le fait de devoir quitter sa terre natale pour s’installer dans un pays étranger aux mœurs inconnues, produit des bouleversements psychiques considérables, surtout au moment de l’adolescence ! À cette période de la vie, il est particulièrement ardu de se confronter aux deuils et aux changements qu’impose la migration. En témoigne, le cas d’une adolescente aux prises avec un contexte migratoire douloureux mettant en exergue la fonction contenante du cadre culturel.
Philosophie et vie dans l’ Apologie de Socrate
Authors: Brancacci Aldo 
Published: April 2020

Cet article se propose de mettre en lumière la centralité du thème de la vie, et du rapport entre vie et pensée, dans la philosophie de Socrate. Ce thème est étroitement lié chez Socrate à la justification du sens de sa propre philosophie, qui repose non pas sur un certain « mode de vie », mais sur une série de principes théoriques forts et clairement définis. Or ces principes ne peuvent se réaliser que lorsqu’ils trouvent leur matière d’actualisation et leur instrument de contrôle dans la réalité de la vie. Cela implique l’élaboration d’un nouveau concept de « vie », ainsi que du concept fondamental de « vivre en philosophant » : ce dernier indique une sorte de déplacement continu du plan de la pensée au plan de la vie, et vice versa, du particulier à l’universel, et vice versa, car seul, chacun des deux est insuffisant.
Le tombeau de la famille de Baux à l’Abbaye de Silvacane. Un art funéraire à l’instar des tombeaux comtaux d’Aix-en-Provence sous Charles Ier d’Anjou
Authors: Hartmann-Virnich Andreas , Bonetti Marie-Pierre , Hansen Heike , Molina Nathalie 
Published: April 2020

En 2013, une mission archéologique conduite par les co-auteurs, confiée au Laboratoire d’Archéologie Médiévale et Moderne en Méditerranée (LA3M UMR 7298 Université d’Aix-Marseille/CNRS) et à l’Inrap (Institut national de recherches archéologiques préventives), eut pour objet la réalisation d’une première campagne d’étude du mobilier lapidaire ex situ de l’abbaye cistercienne de Silvacane dans la basse vallée de la Durance. Le classement des éléments architecturaux en tout genre, mal identifiés, très partiellement inventoriés et inégalement préservés, déposés à l’intérieur comme à l’extérieur du monument, a permis de rassembler, d’identifier et de resituer dans leur contexte architectural des fragments appartenant à un tombeau monumental gothique de la famille des Baux, bienfaiteurs de l’abbaye à l’époque de sa fondation. Or, la conception, l’ordonnance, le style, la modénature et le décor sculpté du prestigieux monument funéraire étaient étroitement apparentés à ceux du tombeau d’Alphonse II, comte de Provence, à l’église Saint-Jean-de-Malte d’Aix, commandé par Charles Ier d’Anjou dans les années 1270, détruit à la Révolution mais connu par une gravure publiée au début du XIXe siècle par Aubin-Louis Millin d’après un dessin de la fin du XVIIIe siècle. L’analogie étroite qui lie les deux monuments, et qui pourrait relever de l’intervention d’une même équipe de sculpteurs qu’il est toutefois impossible de prouver, pose la question du commanditaire du monument, posthume sans doute à l’instar du tombeau aixois, et de sa relation avec la famille comtale. En outre, un examen minutieux des murs de la nef de l’église a mis en évidence des traits d’épure gravés dans le parement, dont le tracé s’accorde à la géométrie du remplage du baldaquin couronnant le gisant, ainsi que du remplage des baies du réfectoire de l’abbaye, dont l’architecture appartient à la même époque précoce du gothique méridional que l’église des Hospitaliers d’Aix : un indice des pratiques de chantier de l’équipe qui pose la question de l’emplacement du tombeau à l’intérieur de l’église abbatiale et qui associe la réalisation du monument à l’achèvement du réfectoire. Ces éléments entrent manifestement dans une stratégie dynastique de la famille de Baux nouvellement liée aux comtes angevins.
Les orientations religieuses de Benoît Himfi († 1380/1381). Un tropisme mendiant de bon aloi ?
Authors: Cevins Marie-Madeleine de 
Published: April 2020

Benoît Himfi, chevalier de cour puis comte-ispan et enfin ban de Bulgarie resté pendant quatre décennies au service du roi de Hongrie Louis Ier, a exprimé de multiples façons son soutien aux ordres mendiants au cours de son existence. Plus que la logique d’imitatio regis qui aurait caractérisé le milieu des officiers angevins, il semble avoir traduit ainsi en actes sa volonté d’enraciner topographiquement son lignage ainsi que son attachement aux saints de la dynastie arpadienne.
