Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have three main limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically.

Introduction: Prehospital and hospital emergency care guidelines have been developed for patients with suspected hip fracture. Initial radiography can identify a number of patients with other injuries, generally pelvic fractures and hip contusions. Little is known about the prognosis for these patients. The aim of this study is twofold: i) to investigate the injury pattern of patients assessed in

In the first part of this thesis discrete time hedging is considered. In paper A an adaptive hedging scheme where the hedge portfolio is re-balanced when the hedge ratios differ by some amount, here denoted eta, is investigated. An expression of the normalized expected mean squared hedging error as eta tends to zero is derived. The result is compared to an earlier result on discrete time hedging o

This paper analyzes Donald Trump’s evolving rhetoric on undocumented migration during the Biden administration, building on previous literature related to the use of language to delegitimize migrants. Employing a discourse analysis based on Laclau and Mouffe’s discourse theory, we examine Donald Trump's remarks surrounding illegal immigrants in the United States through 7 major speeches from 2

The HIBEAM/NNBAR collaboration at the European Spallation Source (ESS) aims to discover processes of baryon number violation, such as neutron-antineutron oscillations, and it furthermore includes searches for sterile neutrons, ultralight axion dark matter particles, and nonzero neutron electric charge. The following investigation presents the characterization of the HIBEAM time projection chamber

The F-FCSR stream cipher family has been presented a few years ago. Apart from some flaws in the initial propositions, corrected in a later stage, there are no known weaknesses of the core of these algorithms. The hardware oriented version, called FCSR-H, is one of the ciphers selected for the eSTREAM portfolio. In this paper we present a new and severe cryptanalytic attack on the F-FCSR stream

We study photoionization of argon atoms excited by attosecond pulses using an interferometric measurement technique. We measure the difference in time delays between electrons emitted from the 3s(2) and from the 3p(6) shell, at different excitation energies ranging from 32 to 42 eV. The determination of photoemission time delays requires taking into account the measurement process, involving the i

One of the fundamental processes in nature is the photoelectric effect in which an electron is ripped away from its atom via the interaction with a photon. This process was long believed to be instantaneous but with the development of attosecond pulses (1 as 10(-18) s) we can finally get an insight into its dynamic. Here we measure a delay in ionization time between two differently bound electrons

The semen coagulum proteins have undergone substantial structural changes during evolution. In primates, these seminal vesicle-secreted proteins are known as semenogelin I (SEMG1) and semenogelin II (SEMG2). Previous studies on the common marmoset (Callithrix jacchus) showed that ejaculated semen from this New World monkey contains semenogelin, but it remained unclear whether it carries both genes
