Kommersialisering och outsourcing av hushållsarbete : RUT-avdrag, migrantarbete och exploatering inom den svenska städindustrin

Privat städhjälp var tidigare ett marginellt fenomen på svensk arbetsmarknad. Precis som den kommersiella städningen så utfördes den framförallt av kvinnor och i synnerhet av invandrarkvinnor. Ersättningen var låg och utbetalades ofta svart och de som använde sig av privat städhjälp var i första hand välbärgade svenska familjer. För majoriteten av svenska hushåll var däremot städning och annat hus

Large Eddy Simulation of Thermoacoustic Instabilities in Bluff-Body Stabilized Flames

The present study investigates the thermoacoustic instability for triangular bluff-body stabilized flames using high fidelity Large Eddy Simulations with finite-rate chemistry. The study includes premixed propane-air combustion, studying the triggering of the thermoacoustic instability for different parameters such as, incoming turbulence intensity, inlet velocity and temperature, and equivalence

LES of Supersonic Combustion in a Mach 2 Cavity-Based Model Scramjet Combustor with Conjugate Heat Transfer and Radiative Heat Transfer

Here we report on reactive Large Eddy Simulations (LES) of flow and combustion in the US Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves combustion of ethylene (C2H4) injected into a cavity from its slanted trailing edge. It has previously been studied experimentally with multiple techniques including particle image velocimetry, shadowgrapy, OH pl

Characterization of Non-Wide-Sense Stationarity for Distributed Massive MIMO Channels

Distributed massive multiple-input multiple-output (MIMO) communication is envisioned as one of the key paradigms of future MIMO systems. To investigate non-wide-sense stationarities (non-WSSs) in distributed massive MIMO channels, this paper first presents an indoor channel measurement campaign, where distributed arrays with a total of 128 elements were implemented. Then relying on the correlatio

Partiell ogiltighet och partiellt upphävande av skiljedom - En kritisk analys i ljuset av NJA 2025 s. 554 (Blue Gas Holding) och NJA 2025 s. 540 (Rydbergs)

Skiljeförfarandet är ett eninstansförfarande som syftar till att snabbt och effektivt åstadkomma en slutlig och bindande skiljedom. Av denna anledning kan en skiljedom inte angripas på materiella grunder. Till skillnad från många utländska skiljeförfarandelagar har en part möjlighet att väcka både ogiltighets- och klandertalan mot skiljedomen som helhet eller i viss del, om skiljenämnden har brustArbitration is a single instance procedure aimed at achieving a final and binding award promptly and efficiently. For this reason, an arbitral award cannot be challenged on substantive grounds. Unlike many foreign arbitration laws, a party may bring an action for invalidity or an action to set aside an arbitral award, in whole or in part, if the arbitral tribunal has failed to comply with procedur

Ray-tracing-assisted High-Resolution Parameter Estimation for Dynamic Millimeter-Wave Channels

An accurate description of the wireless channel is essential to the development of modern wireless systems. In order to mathematically model the propagation channel, one important prior step often done is high-resolution parameter estimation. The estimation accuracy of this step has a significant impact on how well the channel models can represent reality. In this paper, we address this by improvi

Experiments and Large Eddy Simulation of Supersonic Combustion in the Small-Scale Flight Experiment

Supersonic combustion is a critical area of research for advancing high-speed flight technologies, particularly for the development of scramjet engines for hypersonic vehicles. This study employs Finite Rate Chemistry (FRC) Large Eddy Simulation (LES) together with different experimental techniques to study the supersonic flow and thermochemical processes in the Small Scale Flight Experiment (SSFE

Improving neural network efficiency with multifidelity and dimensionality reduction techniques

Design problems in aerospace engineering often require numerous evaluations of expensive-to-evaluate high-fidelity models, resulting in prohibitive computational costs. One way to address the computational cost is through building surrogates, such as deep neural networks (DNNs). However, DNNs may only be an effective surrogate when sufficient evaluations of the high-fidelity model are required suc

Indirect Approach to Mixed-Integer Optimal Control

We study mixed-integer optimal control problem using indirect approaches. The proposed method relies on splitting algorithms which separate the mixed problem into two solvable pieces and then iteratively alternating between the two. The algorithm gives approximated local solutions, and provides lower and upper bounds estimations of the global optimum. Simulations are provided to validate our appro

SIGNATURE KERNEL CONDITIONAL INDEPENDENCE TESTS IN CAUSAL DISCOVERY FOR STOCHASTIC PROCESSES

Inferring the causal structure underlying stochastic dynamical systems from observational data holds great promise in domains ranging from science and health to finance. Such processes can often be accurately modeled via stochastic differential equations (SDEs), which naturally imply causal relationships via 'which variables enter the differential of which other variables'. In this paper, we devel

Staging, Accommodating or Caring : Reviewing the Human Labor Involved in Shaping Robots into Agents

This review examines the hidden and invisible labor humans perform to enable robots to function as agents within Human-Robot Interaction (HRI). While robot agency is often framed as internal and autonomous, this perspective overlooks the relational dynamics that sustain robot functionality in real-world settings. Drawing on feminist theory, the review highlights how humans frequently share the res

How Consumer Culture Grows : The Eigendynamik of Consumption

The current climate crisis has generated social pressure to slow consumption down. Despite this, consumer culture is continuously developing and growing. How is this possible? Our paper provides theoretical clues to this question by developing a novel model of thought for consumption growth, based on Georg Simmel’s notion of Eigendynamik.

Transphobia : A ”New Antisemitism”

In this paper, I explore similarities and differences between contemporary transphobic and anti-Jewish discourses. While scholars have shown entanglements between homophobic and antisemitic discourses in the European 19th century, as well as similarities between contemporary homonationalist and Western philosemitic discourses, less attention has been paid to how anti-trans and anti-Jewish discours
