The stopping powers in silicon of heavy ions, with atomic numbers ranging from 4 to 29, have been determined using a time-of-flight elastic recoil detection analysis (TOF ERDA) set-up. In transmission geometry, the energy loss of heavy elastic recoils in the self-supporting silicon foil of known thickness is measured over a continuous range of recoil energies using time-of-flight (TOF) spectrometr

As offshore wind farms continue to grow in scale and number, wake interaction between turbines represents a significant source of power loss and increased fatigue risk. Consequently, there has been an increased interest in wake control strategies. Wake control strategies aim to mitigate these effects but their comparative effectiveness across power, wake velocity and turbulence intensity is not we

Byggbranschen står för en betydande del av vår klimatpåverkan, både globalt och i Sverige, där en stor andel av samhällets utsläpp av växthusgaser och avfall som genereras kan kopplas till sektorn. I Sverige är den största andelen av avfallet från byggbranschen jord- och schaktmassor och hanteringen av massor inom anläggningsprojekt står för ungefär 16% av de totala utsläppen i projektet. Masshant

This timely book explores the contribution of international human rights and investment law to advancing climate action. It presents a unique perspective on climate change in an international law context, analyzing areas of law that are critical to the achievement of the Paris Agreement’s goals in the absence of sufficient state ambition.

Many circuits in integrated-circuit design require a time-shifted or multi-phase clock. In time-interleaved ADCs, multiple phases enable a higher effective aggregate sampling rate without increasing the individual clock rate. In contrast, in SerDes links, bit throughput increases while keeping each lane at a lower base clock. In 5G and 6G wireless equipment, multiple phases can be used to drive a

We present a generic way to obtain level lower bounds for (promise) CSP hierarchies from degree lower bounds for algebraic proof systems. More specifically, we show that pseudo-reduction operators in the sense of Alekhnovich and Razborov [Proc. Steklov Inst. Math. 2003] can be used to fool the cohomological k-consistency algorithm. As applications, we prove optimal level lower bounds for c vs. ℓ-c

Monitoring insect populations and diversity are important to assess ecosystem health. Traditional trapping and manual identification methods are slow and labor-intensive. Entomological lidar offers an automated alternative for monitoring insects in flight, but classifying species remains a challenge. Building empirical databases through catch-and-release methods is impractical due to the enormous

This thesis investigates whether the unilateral credit valuation adjustment (CVA) of plain-vanilla interest rate swap portfolios can be approximated accurately using a pre- computed library of basis-swap CVAs, avoiding the cost of full Monte Carlo revaluation. The approximation is constructed to require only a yield curve, a swaption volatility surface, and counterparty CDS spreads as inputs. The

Modern Artificial Intelligence (AI) technologies have a rapidly growing impact on a wide range of human activities. AI methods are being used in varied domains such as healthcare, material science, infrastructure engineering, social media, surveillance technologies, and even artistic expression. They have been used for the purposes of drug discovery via protein folding prediction, power usage opti

This thesis investigates acoustic beamforming algorithms for loudspeaker arrays aimed at creating steerable directed sound fields under practical size constraints. Simulations evaluated delay-and-sum (DS), least-squares (LS), contrast-control (CC), acoustic-energy-difference (AED), and sound-power-minimisation (SPM) using beamwidth, acoustic contrast, and efficiency in the range 300-3400 Hz. After

Air quality is affected by airborne particles and gases such as PM2.5, volatile organic compounds (VOC), and nitrogen oxides (NOx), as well as environmental factors such as humidity and temperature, all of which influence human health and the spread of airborne diseases. While research grade air quality instruments provide accurate measurements, they are often large, expensive and difficult to uti

The Swedish Sea Rescue Society’s (SSRS) maritime Search and Rescue (SAR) op- erations can be enhanced through the use of fixed-wing unmanned aerial vehicles (UAVs), which offer extended range and rapid area coverage. However, recovering such aircraft aboard small, moving rescue vessels remains a significant challenge due to continuous wave-induced motion (pitch, roll, and yaw) and the absence of c
