This thesis evaluates three interest rate models the HW1F, HW2F, and CIR++ from a risk management perspective. Through simulation, we examine their ability to generate realistic yield curves, as well as their impact on exposure metrics and CVA in different market environments. The CIR++ model consistently produces the highest and most conservative PFE estimates while also maintaining calibration
The anterior cruciate ligament (ACL) is the most frequently injured ligament in the knee, mainly due to its role as a primary joint stabiliser. In sports science, non-contact ACL injuries are commonly linked to change-of-direction (COD) manoeuvres, especially in multidirectional team sports. Given the long rehabilitation times and risk of long-term consequences, ACL injury prevention remains a maj
Merging of maps, such as 3D point clouds obtained from Structure-from-Motion or visual SLAM, can enhance robustness and expand covered areas in applications like multi-robot systems or augmented reality. When direct data fusion is difficult, an alternative approach is to align pose trajectories. This work investigates the use of rotation averaging as a method for indirect map merging, especially f
This thesis presents the design and implementation of a web-based simulator, developed to support students in the introductory course in automatic control at LTH. The simulator is meant to serve as a preparatory tool for the laboratories that revolve around two interconnected water tanks, and provides an interactive environment for students to explore system dynamics and PID control prior to atten
Climate change is intensifying globally, leading to rising temperatures. The Arctic being a vulnerable and extreme environment faces an enhanced warming effect, referred to as the Arctic amplification. In this rapidly changing environment, high amounts of carbon (1,460 – 1,600 Pg C) are stored in permafrost. This is four times the amount of carbon being emitted by humans in modern times. Increasin
This thesis investigates how high-level planning principles can be deterministically and algorithmically incorporated into a sampling-based motion planner by modifying the structure of the RRT* algorithm. In particular, the requirement to always end a planned route by a reversing maneuver can be directly imposed through the expansion and connection logic of bidirectional search-trees, rather than
Among the multidimensional effects that forced displacement has on population welfare, the economic ones may be measured in various ways: one of them is assessing the effect of being a forced migrant in the probability of accessing the labor market in the destination communities in Colombia. This is obtained through the estimation of a logit model which uses data from the “Survey in marginalized a
The advent of AlphaFold and consumer large language models have elicited unprecedented development of artificial intelligence (AI). AI has had substantial impact in every area of research, including in molecular biology. This is principally in thanks to contributions to the Protein Data Bank and various genome sequence databases, providing an astronomical amount of data for model training. These d
The paper considers the solution of the boundary value problem (BVP) consisting of the Helmholtz equation in the region D with a rigid boundary condition on ∂D and its reformulation as a boundary integral equation (BIE), over an infinite cylindrical surface of arbitrary smooth cross-section. A boundary integral equation, which models three-dimensional acoustic scattering from an infinite rigid cyl
This paper reviews historical developments and recent challenges in full scale bridge testing and introduces results- and hypotheses related to an ongoing bridge testing research project. This research project encompasses full scale bridge testing in conjunction with bearing capacity analysis as well as related contact- and non-contact monitoring procedures combined with a decision analytical appr
The problem of finding maximum (or minimum) witnesses of the Boolean product of two Boolean matrices (MW for short) has a number of important applications, in particular the all-pairs lowest common ancestor (LCA) problem in directed acyclic graphs (dags). The best known upper time-bound on the MW problem for n× n Boolean matrices of the form O(n2.575) has not been substantially improved since 2006
Due to the ongoing urbanisation, the urban environment will consist of extended impervious areas, such as roof tops, roads and parking lots. During rainfall events these kinds of impermeable areas will cause a faster and larger response in runoff, which can lead to an increased load on the storm-water system and thus increase the risk of flooding. In certain areas, the situation will be further wo
There have been several studies which indicate a preferential invasion towards younger red blood cells (RBCs) for the malarial parasite, P. Falciparum. Knowledge about a preferential mechanism could aid in the development of novel anti-malarial drugs. While the preference in these reports has been studied with density-separation of red blood cells, separating the cells by deformability may be a mo
It is said that coreference is difficult to explain, but easy to comprehend; everyoneknows coreference, they just don’t know that they do. We trained a computer toknow it too! Coreference resolution is the identification of phrases that refer to the same entity in a text. Current techniques to solve coreferences use machine-learning algorithms, which require large annotated data sets. Such annota
The constantly increasing awareness of protecting the environment has put electrical roads in the spotlight as an alternative solution to fossil driven means of transport. Dan Zethraeus has developed an innovative idea for a prototype electrical road which conductively supplies power to the cars whilst driving. The concept is to place a line of short rail segments in the middle of the drive lanes
