A multi-variable adaptive controller is derived as the explicit solution to a minimax dynamic game. The minimizing player selects the control action as a function of past state measurements and inputs. The maximizing player selects disturbances and model parameters for the underlying linear time-invariant dynamics. This leads to a Bellman equation that can be solved explicitly for the case with un
Coherent extreme ultraviolet (XUV) radiation can be generated in a tabletop configuration via high-order harmonic generation (HHG) in gases. While HHG is inherently inefficient, increasing the conversion efficiency (CE) is crucial for many applications, such as coincidence spectroscopy [1] and coherent imaging [2], which require high XUV throughput. Previous calculations suggest that one way to im
Three different semiconductor nanowires are combined into a single optoelectronic artificial neuron. Our device provides a path towards low power computations with significantly reduced circuit footprint, thus addressing critical limitations in neuromorphic photonics. The false-coloured scanning electron micrograph shown in Figure 1a depicts the fabricated nanowire neuron. Two pin-doped InP nanowi
Photonics-based approaches to neuromorphic hardware offer advantages in speed and connectivity but often suffer from large device footprints.[1] Here, we present an ultra-compact artificial neuron built from semiconductor nanowires. A scanning electron micrograph of the nanowire device is presented in Figure 1a. Inside the dashed box, we show the neuron built from three III-V nanowires - two InP p
This paper provides a practical guide on how to effectively use the MARRYS helmet for recording and analyzing jaw movements in speech research. Rather than introducing the device itself, which has been described in detail in Gudmundsson et al. (2024), this guide focuses on the setup, data collection, and analysis workflows essential for successful experimental work. Applications include language l
Methanol can be produced renewably and used in compression ignition (CI) engines as a replacement for fossil diesel. However, methanol is a low cetane fuel, creating challenges in achieving stable operation, particularly at low load. One potential solution is through surface ignition via a glow plug. In this work, experiments were conducted on a methanol-fueled 2.1 L single cylinder engine instrum
Robotic systems often face execution failures due to unexpected obstacles, sensor errors, or environmental changes. Traditional failure recovery methods rely on predefined strategies or human intervention, making them less adaptable. This paper presents a unified failure recovery framework that combines Vision-Language Models (VLMs), a reactive planner, and Behavior Trees (BTs) to enable real-time
Decarbonising the built environment is essential to mitigating the climate crisis, as buildings significantly contribute to greenhouse gas emissions. Adaptive reuse presents a sustainable alternative to demolition and new construction. This study evaluated the Global Warming Potential (GWP) of an adapted building through renovation and operation across three scenarios, compared to a reference scen
Semiconductors use on-chip components, referred to as instruments, for test, debugging, firmware programming, configuration and other important functions. The instruments are needed to ensure proper device operation, however, they may be exploited by an adversary in an attack. With many different actors involved in semiconductor development and manufacturing, it becomes important to restrict acces
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
The integration of machine learning (ML) into software operations (MLOps) has significantly increased the demand for data to train and test models, making data sharing and reuse essential to mitigate the high costs of data collection and preprocessing. This study aims to advance the understanding of data sharing within an MLOps context by examining the establishment and governance of a data ecosys
In this study we investigated the tongue and jaw movements during heavy metal growling in comparison to modal voice to enlighten us about the relationship between the laryngeal and oral articulator. Similarly to harsh voice, growling employs supraglottic structures like the ventricular and aryepiglottic folds. Previous research suggests that the tongue dorsum assists in laryngeal constriction by r
Ensuring functional safety is crucial for the deployment of autonomous systems in real-life dynamic environments, as they must operate reliably and safely among humans. However, existing safety systems are designed with a closed-world assumption and can over-constrain the system by shutting down the robot at every safety violation, limiting the robot’s ability to complete its tasks. To address thi
Konstruktiv länkning, studentaktivitet och föreläsningar är tre grundstenar i högre utbildning. Men föreläsningen som undervisningsform har kritiserats: ”Det finns gott om högskolepedagogisk litteratur som förklarar varför föreläsningen är olämplig för att stimulera lärande. Ändå fortsätter vi föreläsa”, skriver Andreas Håkansson (2017, s. 40) i en artikel som trots allt landar i att denna undervi
De senaste 20 åren har humanioraintegrering i professionsutbildning varit på frammarsch i Sverige, både som forskningsfält och högskolepedagogisk praktik. Detta syns bland annat på bildandet av ett antal tvärvetenskapliga centra och program med sådan integrering i fokus. Den akademiska litteraturen om humanioraintegration i professionsutbildning visar att utvecklingen i Sverige är en del av en int
