Dropping the Gloves, Driving the Play? Reassessing the Role of Fighting in Modern NHL Games
Get PDFThis paper investigates the evolving role of fighting in NHL hockey by analyzing over one million play-by-play events from the 2021-22 to 2023-24 seasons. Using Corsi as a proxy for offensive activity, we find that fights are associated with short-term increases in game intensity - particularly for trailing teams. A logistic regression model further shows that fights are more likely in games with more hits and when score differentials are large. These findings suggest that fighting continues to shape game momentum and fan experience in subtle and measurable ways
Att ha ett eget djur och att vara ett: Representationer av barns och djurs relationer i filmen Tjorven, Båtsman och Moses
Get PDFArtikeln fokuserar på barn och djurs relationer till varandra i den svenska klassiska barnfilmen Tjorven, Båtsman och Moses (1964). Den utgår från mediestudier, barndomssociologi och djurstudier för att studera hur representationer av barns och djurs relationer formas av föreställningar och av funktioner i filmens narrativ. Med inspiration från visuell diskursanalys visas den mångfasettering av representationer av barns och djurs relationer som filmen erbjuder. Både barn och djur innehar huvudroller, visar egen handlingskraft och utvecklas som karaktärer genom filmen. Föreställningar om både barn och djur används som viktiga byggstenar i narrativet. En aspekt av barn-djur-relationen som tydliggörs är hur viktigt det är för barnen att ha ett eget djur. Även djuren behöver bevisa sig som personligheter med omsorg och tillgivenhet för barnen för att de ska kunna skapa relationer med barn i filmberättelsen. Analysen visar därmed hur relationer byggs upp, mellan vilka barn och vilka djur de formas och hur relationerna även i sin mångfasettering är färgade av snäva föreställningar om hur barn och djur förväntas vara
Kentaurer i Ödesryttarna: Rumslighet och kroppslighet i häst-människa-relationer
Get PDFIn my work with the first out of two trilogies of Soul Riders by Helena Dahlgren, I examine how the human-horse relationship forms centaurs in the story. The centaur is formed when two individuals in a complex web of parries and responses become so coordinated in their movements that it is no longer possible to distinguish where one body’s movement ends and where the other’s begins. The concept is based on Bornemark’s theory of the centaur as a phenomenological being, in other words, as an experience of the body. With support from Donovan’s and Mane’s theories, I further argue that the horses in the books are regarded as subjects in a dialogue that violates the humanistic idea that man, due to his rationality, stands above the animal in a hierarchical order. With that in mind, I am presenting the connection between horse and rider as a bodily and a subjective transformation, a shift that defies the notion that the rational human and the non-rational non-human (the horse) would be binary opposites. But the centaur is not unconditional, an argument that is supported by the fact that some of the equipages in the books fail to form centaurs. If the rider tries to make the horse submit to the human will by using tools that injure the horse, their movements will not create a united body. My aim is to show that viewing the horse as a subject, and letting the distinction between human and animal dissolve is a prerequisite for the centaur.

Att tämja den vilda hästen: Didaktiska relationer i hästboken som äventyr och vardagsrealism: Walter Farleys Svarta hingstens son (1947) och Lisbeth Pahnkes Britta, Silver och Billy (1971)
Get PDFIn many horse/pony stories there is a recurring narrative figure, a trope: the taming of a wild horse. In the process of taming, the wild horse interacts with domesticated/domesticating humans, and this process is shaped by didactic relations, imbued with power and emotion. This text will explore, through comparative analysis and close reading, and by looking into the didactic discourse at play, how the process of taming the wild horse is represented in Walter Farley’s Son of the Black Stallion (1947) and Lisbeth Pahnke’s novel Britta, Silver och Billy (1971). How are human-animal didactic relations represented and depicted within these two differing examples of the horse/pony book genre? Also, what are the didactic aspects of the horse/pony book genre in relation to its readers? And, how are the qualities of being wild represented in these two novels, where Farley writes within the frames of the adventure story, more geared towards an audience of boys, and Pahnke’s narrative is closer to the everyday realism of the riding school and more appealing for girl readers? How are the didactic elements, implicit in the horse/pony book-genre as well as the riding practice, involved in the taming process? The results of the study display a presence of realistic didactic elements in Farley’s adventure story while aspects significant of the adventure story are found within the frame of the realistic novel by Pahnke, and these elements and aspects interact with the ways in which the didactic authority is presented in the process of taming. This is also connected to how the legitimacy of the didactic position is achieved, related to gender, age and experience. The study also reveals a difference regarding the perception of wildness between the pony and the thoroughbred horse.

Expanding an Open-Source Modelica-Compliant Package of Generic Renewable Energy Source Models: Implementation of the REEC_D and REGC_B Models in Modelica and OpenIPSL
No full textPower systems undergoing large-scale renewable deploymentrequire accurate dynamic models of inverter-basedtechnologies such as solar photovoltaic plants, windturbine generators, and battery energy storage systems toperform the require studies that would allow to assess andmaintain power grid stability. The second generation of theWestern Electricity Coordinating Council (WECC) genericrenewable energy system (RES) models provides a generalframework for modeling inverter-based resources in powersystem dynamics and stability studies. In this paper, weexpand the existing Modelica-compliant open-sourceOpenIPSL.Electrical.Renewables package by implementing theRenewable Energy Generator/Converter B (REGC_B) model alongwith the Renewable Energy Electrical Controller (REEC\D)model, according to the second-generation WECC RESframework. Using Modelica's object-oriented features, theimplementation emphasizes modularity and reusability inbuilding scalable power system models using the OpenIPSLlibrary. This work highlights the potential of usingModelica and OpenIPSL to support a standardized, scalabledevelopment of inverter-based RES models within the WECCframework, and extents the only fully Modelica-compliantopen-source package that implements these models
Towards Integration of PeN-ODEs in a Modelica-based workflow
Get PDFHybrid modeling – the combination of first-principle modelsand machine learning – offers the potential to increasemodel accuracy while reducing modeling effort. Althoughapproaches for creating hybrid models from systemsimulation models exist, the unique characteristics ofModelica-based, object-oriented models – such as modularityand reusability – can, as of today, not be utilized. Inthis contribution, we explore approaches for bridging thisgap to enable the use of hybrid models with Modelica. Keychallenges of architecture definition, training environmentand reintegration of the trained machine learning partsinto a Modelica model are addressed. To illustrate ourapproach, we present a case study involving a SCARA robot.This example demonstrates a partially integrated workflowfor hybrid modeling, intended to serve as a foundation andmotivation for further research
Automatic Modelica Package and Model Generation from Templates and Data Files with Python, Exemplified with URDF
Get PDFCreating correct Modelica models and packages fromtemplates and data files describing a multi-physics systemis useful in numerous situations. For example, in layingout power plants, designing airplane air conditioning orchemical reactions. This publication shows twopossibilities of doing this with an example from roboticsdesign and simulation. The URDFModelica library containstemplates for links, joints and whole robots that can bemobile or stationary. The library also has a Python scriptthat takes a valid URDF file as input. With minimal manualprocessing of this input file, a complete robot simulationpackage is created automatically. Alternatively, the inputfile, translated to a Modelica record, can be used to setthe parameters and connections of a generic robot model.The URDFModelica library has already been successfully usedfor quick generation of first Modelica simulations ofexisting robots or robots yet to be fully developed. Thegeneral structure and approach can be adapted to otherapplication domains without much effort. It is planned torelease URDFModelica as open source Modelica library
FMI Meets SystemC: A Framework for Cross-Tool Virtual Prototyping
Get PDFAs systems become more complex, the demand for thoroughtesting and virtual prototyping grows. To simulate wholesystems, multiple tools are usually needed to coverdifferent parts. These parts include the hardware of asystem and the environment the system interacts with. TheFunctional Mock-up Interface (FMI) standard forco-simulation can be used to connect those tools.The control part of modern systems is usually a computingunit, such as a System-on-a-Chip (SoC) or MicrocontrollerUnit (MCU), which executes software from a connected memoryand interacts with peripherals. To develop the softwarewithout requiring access to the physical hardware,full-system simulators, so-called Virtual Platforms (VPs),are commonly used. The industry standard framework for VPdevelopment is SystemC TLM. SystemC provides interfaces andconcepts that enable modular design and model exchange.However, SystemC lacks native FMI support which limits theintegration into broader co-simulation environments.This paper presents a novel framework to control andinteract with SystemC-based VPs using the FMI. We present acase study showing how a simulated temperature sensor in aSystemC simulation can obtain temperature values from anexternal tool via FMI. This approach allows the unmodifiedtarget software to run on the VP and receive realisticenvironmental input data such as temperature, velocity, oracceleration values from other tools. Thereby, extensivesoftware testing and verification is enabled. By havingtests ready and the software pre-tested using a VP once thephysical hardware is available, certifications like ISO26262 can be done earlier
Design and Simulation Validation of Steam Power Systems Based on MBSE
Get PDFSteam power systems, as one of the critical power systemsin industrial applications, require rigorous design andverification processes. Model-Based Systems Engineering(MBSE) provides a structured approach to decomposing systemarchitecture from top to bottom and enablingmulti-disciplinary collaborative design, ensuring preciserequirement management and efficient design processes. Toaccelerate the iterative design and verification of steampower systems, this paper employs the SysML language toconduct requirement, functional, structural, and parametricanalyses, thereby completing the system architecturedesign. The seamless transformation from system designarchitecture to system simulation architecture is achievedbased on the SysML-to-Modelica tool. Additionally, Modelicasimulation technology is utilized to construct simulationmodels and perform dynamic scenario analyses of the system.Innovatively, this paper proposes a closed-loop technicalapproach for steam power system design, simulation, andverification, which effectively optimizes system design andimproves the efficiency of both design and verificationprocesses
