Transportasi merupakan sesuatu hal yang sangat penting dalam menunjang kehidupan masyarakat sehari-hari. Dengan adanya transportasi orang bisa melakukan aktivitas dengan lebih cepat dan efisien karena dengan adanya transportasi akan mempermudah orang dalam berpindah tempat dari satu tempat ke tempat lain yang dituju dalam waktu yang relative singkat. Tetapi transportasi juga dapat menimbulkan beberapa permasalahan yaitu seperti kecelakaan berlalu lintas. Masalah kecelakaan lalu lintas merupakan masalah yang serius, karena akibat dari kecelakaan menyebabkan beberapa aspek baik langsung maupun tidak langsung. Angka Kecelakaan lalu lintas di Kabupaten Karangasem tahun 2019 meningkat cukup signifikan (Polres Karangasem 2020). Meningkatnya angka kecelakaan di Kabupaten Karangasem pada tahhun 2019 maka perlu dilaksanakan penelitian untuk dapat mengetahui tingkat kecelakaan dan lokasi dimana sering terjadinya kecelakaan lalu lintas. Sehingga dapat mengurangi angka kecelakaan lalu lintas di Kabupaten Karangasem. Penelitian ini dilaksanakan dengan menganalisa data kecelakaan yang diperoleh dari Polres Karangasem dari tahun 2016 sampai dengan 2020. Dari data tersebut akan dibuatkan rekapan kecelakaan lalu lintas yang terjadi di ruas jalan padang bai serta dibuatkan pembobotan kecelakaan lalu lintas berdasarkan Angka Ekuivalen Kecelakaan (AEK) kemudian diperoleh jumlah kecelakaan lalu lintas dan bobot tertinggi kecelakaan per KM. KM dengan jumlah kejadian kecelakaan terbanyak dan bobot tertinggi merupakan daerah rawan kecelakaan lalu lintas. Berdasarkan analisa data, diperoleh bahwa pada KM 25 paling banyak terjadi kecelakaan dengan jumlah 6 kejadian kecelakaan lalu lintas dengan bobot 64. Sehingga lokasi dari daerah rawan kecelakaan lalu lintas di ruas jalan raya padang bai yaitu pada KM 25.
A quantitative approach to testing effects of different expertise levels, playing positions, and game situations on shared tactical knowledge in football teams
Authors: Steiner Silvan , Weidtmann Samuel 
Published: November 2022

According to the social cognitive view, the organization of sports team behavior is underpinned by the existence of shared knowledge. This study considers tactical position knowledge as an example of shared macro-level plans involved in organizing team behavior. A coach- and a team-referenced measure of sharedness in tactical knowledge are introduced to test whether expert sport teams share knowledge to a higher degree than weaker sport teams (RQ1), whether the time spent performing a common task predicts shared knowledge (RQ2), whether role-specific specializations are mirrored in the degree to which athletes share tactical knowledge (RQ3) and whether tactical knowledge is shared to different degrees in defensive as opposed to offensive game situations (RQ4).
Members of 17 football teams (N = 296) participating in championships at different levels of the Swiss National Football Federation took part in the scenario-based, cross-sectional study. Participants marked the positions of their team members according to their tactical playing strategy. Data were analyzed using multiple regression and mixed linear model procedures.
Teams playing at the professional level had significantly more consistent ideas about their teams’ tactical positions than those at the amateur level. Within the amateur level, no consistent pattern of increasing consensus as the playing level increased was found. Sharedness in tactical knowledge increased with the duration of team membership when considering the team-referenced congruency measure. However, the effect was low. Overall, there was a pattern of defenders and midfielders agreeing with their team reference positions more than did goal keepers and forwards. Sharedness was generally higher in defensive situations than in offensive situations.
The presented approach to measuring shared knowledge offers new insights into a yet under-researched field. It can be adopted to answering research questions in other sports and situations involving other measures of team performance assumed to be affected by shared knowledge.
The judgmental failures of the Western European states towards the Russian Federation by perceiving it through European values.
Authors: Chabska Katarzyna 
Published: November 2022

ObjectivesThe purpose of this article is to show the Western European judgmental failures towards Russia by perceiving it through European values. These failures have a negative impact on European security and all of them appeared because Russia was considered the European state and the European values were put in Russia. In fact, the Russian Federation is only a geographic part of Europe, but no longer a part of European civilization.MethodsThe research was conducted by analyzing the relationship between Western European countries and the Russian Federation, as well as analyzing the general condition of Russian society and Russian foreign policy.ResultsThis article states that Western European countries made a critical mistake by adopting
European values to the Russian Federation. This hypothesis was composed by addressing the following question: What is the grand strategy of the Russian Federation? What are judgmental failures and what are their types? What judgmental failures were made by Western Europe towards Russia?ConclusionsThe Russian Federation for the past years has been treated by the Western European states as a strategic business partner, however as it can be seen now, this approach was misleading and was a complete failure in terms of European security. Countries such as France and Germany had not seen Russia as an enemy of the West.

Published: November 2022

Las turbinas Hidrocinética son máquinas hidráulicas que aprovechan energía cinética de las corrientes de agua por pasada, no requieren infraestructura de obras civiles para su instalación y son ideales para aprovechar energía en potencias pequeñas de 1 a 10 kW. Se adecua para abastecer energía hasta tres familias para uso en iluminación y electrodomésticos.
El diseño y fabricación de estas turbinas tiene falencias por no existir un procedimiento detallado, más aún en países en vías de desarrollo donde se utiliza tecnología apropiada para su aplicación.
El presente proyecto desarrolla un procedimiento de selección de alabes para la turbina acorde a la eficiencia de los coeficientes de sustentación y arrastre desarrollados por algoritmo Xfoil, luego esta selección se procede al análisis de potencia que desarrolla la turbina de acuerdo a la metodología BEM, particularmente da un énfasis al procedimiento del cálculo de la potencia para distintas condiciones de rotación en función del ángulo de ataque del fluido en alabe y así mismo analiza el ángulo de paso del álabe.
El presente estudio logra clarificar el comportamiento de la turbina hidrocinética para distintas rotaciones y velocidades de agua de río, puede aprovechar mejor la potencia, quiere decir que el programa desarrollado, puede lograr graficar una curva de potencia de la turbina hidrocinética con el fin de establecer la rotación óptima, ángulo de ataque, ángulo de paso y diámetro de la turbina.
el programa desarrollado en Excel permite también exportar la geometría del alabe optimizada para una potencia y velocidad de agua, exportarla mediante macros en Visual Basic para el software de diseño SolidWorks la geometría final, con el fin de hacer los análisis a resistencia mecánica y comportamiento con el fluido en softwares ANSYS CFD.
Para este estudio se hizo una revisión de aproximadamente 60 tesis y se llegó a la conclusión que no existe un procedimiento claro para determinar la potencia en función de las anteriores variables.
La metodología utilizada es absolutamente teórico analítico con la metodología BEM, pero se realizó las verificaciones en software ANSYS CFD el comportamiento del fluido dentro la turbina para completar y establecer las presiones que ejerce el flujo de agua en los álabes y de tal manera de poder analizar la residencia de los álabes y se puede validar la estela de agua con el fin de descartar la turbulencia que podría provocar vibraciones en el rotor con software Qblade.

Published: November 2022

En Ecuador en los últimos años se ha evidenciado cada vez más, que el agua aprovechable es más escaza y con una distribución inequitativa, ya que no se encuentra en los sectores de mayor desarrollo agrícola, para esto, se realizan obras de almacenamiento de agua para diferentes usos, como la agricultura, una de estas obras es el embalse San Vicente en la provincia de Santa Elena.
Los enfoques utilizados en este documento buscan determinar si las condiciones del área de estudio son aptas para transportar agua desde el embalse hasta un determinado punto el cual puede ser un reservorio en la comuna Salanguillo.
El estudio determinó que la evaluación de la ruta optima es un problema complejo de criterios múltiples con objetivos en conflicto que necesitan equilibrio, utilizando la evaluación multicriterio (EMC) para evaluar los diferentes factores necesarios para encontrar rutas óptimas, y luego se usó el análisis de ruta de menor coste para encontrar la ruta optima, que no es necesariamente la de la distancia más corta.
Bajo los criterios planteados, no existe una ruta óptima para conducir el agua por gravedad desde el embalse San Vicente hasta un punto especifico de la comuna Salanguillo, principalmente por factores topográficos del área de estudio.

Abstract
This paper reports on the γ-ray properties of the 2018 Galactic nova V392 Per, spanning photon energies ∼0.1 GeV–100 TeV by combining observations from the Fermi Gamma-ray Space Telescope and the HAWC Observatory. As one of the most rapidly evolving γ-ray signals yet observed for a nova, GeV γ-rays with a power-law spectrum with an index Γ = 2.0 ± 0.1 were detected over 8 days following V392 Per’s optical maximum. HAWC observations constrain the TeV γ-ray signal during this time and also before and after. We observe no statistically significant evidence of TeV γ-ray emission from V392 Per, but present flux limits. Tests disfavor the extension of the Fermi Large Area Telescope spectrum to energies above 5 TeV by 2 standard deviations (95%) or more. We fit V392 Per’s GeV γ-rays with hadronic acceleration models, incorporating optical observations, and compare the calculations with HAWC limits.

Abstract
We report on results from a 1 yr soft X-ray observing campaign of the ultraluminous X-ray pulsar NGC 300 ULX-1 by the Neutron star Interior Composition Explorer (NICER) during 2018–2019. Our analysis also made use of data from Swift/XRT and XMM-Newton in order to model and remove contamination from the nearby eclipsing X-ray binary NGC 300 X-1. We constructed and fitted a series of 5 day averaged NICER spectra of NGC 300 ULX-1 in the 0.4–4.0 keV range to evaluate the long-term spectral evolution of the source, and we found that an absorbed power-law model provided the best fit overall. Over the course of our observations, the source flux (0.4–4.0 keV; absorbed) dimmed from 2 × 10−12 to below 10−13 erg s−1 cm−2 and the spectrum softened, with the photon index going from Γ ≈ 1.6 to Γ ≈ 2.6. We interpret the spectral softening as reprocessed emission from the accretion disk edge coming into view while the pulsar was obscured by the possibly precessing disk. Some spectral fits were significantly improved by the inclusion of a disk blackbody component, and we surmise that this could be due to the pulsar emerging in between obscuration episodes by partial covering absorbers. We posit that we observed a low-flux state of the system (due to line-of-sight absorption) punctuated by the occasional appearance of the pulsar, indicating short-term source variability nested in longer-term accretion disk precession timescales.
Multiple Regions of Nonthermal Quasiperiodic Pulsations during the Impulsive Phase of a Solar Flare

Abstract
Flare-associated quasiperiodic pulsations (QPPs) in radio and X-ray wavelengths, particularly those related to nonthermal electrons, contain important information about the energy release and transport processes during flares. However, the paucity of spatially resolved observations of such QPPs with a fast time cadence has been an obstacle for us to further understand their physical nature. Here, we report observations of such a QPP event that occurred during the impulsive phase of a C1.8-class eruptive solar flare using radio imaging spectroscopy data from the Karl G. Jansky Very Large Array (VLA) and complementary X-ray imaging and spectroscopy data. The radio QPPs, observed by the VLA in the 1–2 GHz with a subsecond cadence, are shown as three spatially distinct sources with different physical characteristics. Two radio sources are located near the conjugate footpoints of the erupting magnetic flux rope with opposite senses of polarization. One of the sources displays a QPP behavior with a ∼5 s period. The third radio source, located at the top of the postflare arcade, coincides with the location of an X-ray source and shares a similar period of ∼25–45 s. We show that the two oppositely polarized radio sources are likely due to coherent electron cyclotron maser emission. On the other hand, the looptop QPP source, observed in both radio and X-rays, is consistent with incoherent gyrosynchrotron and bremsstrahlung emission, respectively. We conclude that the concurrent, but spatially distinct QPP sources must involve multiple mechanisms which operate in different magnetic loop systems and at different periods.
Stellar Obliquity from Spot Transit Mapping of Kepler-210
Authors: Valio Adriana , Araújo Alexandre 
Published: November 2022

Abstract
Stellar obliquity, the angle between the stellar spin and the perpendicular to the planetary orbit, also known as the spin–orbit angle, holds clues to the formation and evolution of planetary systems. When a planet transits a star periodically, it may cross in front of a stellar spot, producing a noticeable signal on the transit light curve. Spot transit mapping can be used to measure stellar obliquity. Here we present the analysis of Kepler-210, a K-dwarf star with two mini-Neptune-size planets in orbit. Interestingly, the spot mapping from the outer planet, Kepler-210 c, resulted in a spot distribution with no spots detected at longitudes >38°, whereas the spots occulted by Kepler-210 b displayed all range of longitudes. The best explanation for this was that Kepler-210 c exhibited an inclined orbit, while the orbit of Kepler-210 b was parallel to the stellar equator. Thus, transits of Kepler-210 c occulted different latitude bands of the star. The observed maximum spot topocentric longitude of 38° implied an orbital obliquity of 18°–45° for Kepler-210 c. Further considering a symmetric spot distribution in latitude with respect to the stellar equator, the obliquity was restricted to 34.°8, implying a maximum spot latitude of 40°. The differential rotation profile calculated from the oblique orbit for Kepler-210 c agreed with that obtained from the spots occulted by Kepler-210 b. Combining results from both planets yields a rotational shear of ΔΩ = 0.0353 ± 0.0002 rad day−1 and a relative rotational shear of 6.9%. The causes of the Kepler-210 c misalignment remain to be explained.
Statistical Analysis of the Radial Evolution of the Solar Winds between 0.1 and 1 au and Their Semiempirical Isopoly Fluid Modeling

Published: November 2022

Abstract
Statistical classification of the Helios solar wind observations into several populations sorted by bulk speed has revealed an outward acceleration of the wind. The faster the wind, the smaller this acceleration in the 0.3–1 au radial range. In this paper, we show that recent measurements from the Parker Solar Probe (PSP) are compatible with an extension closer to the Sun of the latter Helios classification. For instance, the well-established bulk speed/proton temperature (u, T
p) correlation and bulk speed/electron temperature (u, T
e) anticorrelation, together with the acceleration of the slowest winds, are verified in PSP data. We also model the combined PSP and Helios data using empirical Parker-like models for which the solar wind undergoes an “isopoly” expansion: isothermal in the corona, then polytropic at distances larger than the sonic point radius. The polytropic indices are derived from the observed temperature and density gradients. Our modeling reveals that the electron thermal pressure has a major contribution in the acceleration process of slow and intermediate winds (in the range of 300–500 km s−1 at 1 au) over a broad range of distances and that the global (electron and proton) thermal energy alone is able to explain the acceleration profiles. Moreover, we show that the very slow solar wind requires, in addition to the observed pressure gradients, another source of acceleration.

computed with the ÆSOPUS code under the assumption of thermodynamic equilibrium. In comparison to the previous version, ÆSOPUS
1.0, we updated and expanded molecular absorption to include 80 species, mostly using the recommended line lists currently available from the ExoMol and HITRAN databases. Furthermore, in light of a recent study, we revised the H− photodetachment cross section, added the free–free absorption of other negative ions of atoms and molecules, and updated the collision-induced absorption due to H2/H2, H2/H, H2/He, and H/He pairs. Using the new input physics, we computed tables of Rosseland mean opacities for several scaled-solar chemical compositions, including Magg et al.'s most recent one, as well as α-enhanced mixtures. The differences in opacity between the new ÆSOPUS
2.0 and the original ÆSOPUS
1.0 versions, as well as other sets of calculations, are discussed. The new opacities are released to the community via a dedicated webpage that includes both precomputed tables for widely used chemical compositions and a web interface for calculating opacities on the fly for any abundance distribution.

Abstract
We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars at a distance of 12.5 kpc, and further characterized it with Gaia astrometry and follow-up spectroscopy. Specter is a 25° × 1° stream of stars that is entirely invisible until strict kinematic cuts are applied to remove the Galactic foreground. The spectroscopic members suggest a stellar age τ ≳ 12 Gyr and a mean metallicity

≈ −2.6, Specter is by far the least-luminous dwarf galaxy stream known. We estimate that dozens of similar streams are lurking below the detection threshold of current search techniques, and conclude that spectroscopic surveys offer a novel means to identify extremely low surface brightness structures.
