High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. This thesis explores sc
A phenomenological model for explaining the magnetic properties of MnAs nanocrystals embedded in GaAs is proposed. It is shown that experimental data of DC magnetization as a function of temperature, obtained according to zero-field-cooled and field-cooled protocols, can be understood assuming a transition of the system from a low temperature state in which very slow dynamics is observed(frozen st
Investigations of past fires suggest that building occupants faced with a fire have problems defining the severity of it, especially in the early stages of the fire. An experiment was therefore carried out to study people’s ability to estimate fire growth, and their perceived ability to extinguish a fire using a portable fire extinguisher. A total of 535 persons, namely 304 men and 231 women, were
Sophisticated statistical analyses are common in ecological research, particularly in species distribution modeling. The effects of sometimes arbitrary decisions during the modeling procedure on the final outcome are difficult to assess, and to date are largely unexplored. We conducted an analysis quantifying the contribution of uncertainty in each step during the model-building sequence to variat
The focus in this thesis is on how medical patient records have developed and changed due to the modernization processes in the Swedish health care system during the period 1900– 1986. The processes are followed and analyzed by the written means of communication in use. These are: handwritten text by the physician; type written text produced by a new profession (the medical secretary), and lastly
The eighteenth century marks a watershed in European intellectual history. It witnessed the development of many civil rights ideas that were prerequisites for the emergence of modern political systems. One principle that appears to be supported by numerous empirical examples is that evolving political pluralism fostered the right to express one’s views with a certain degree of freedom. This articl

With the increasing share of renewable energy sources in the energy system, an increased demand for stabilizing the grid frequency has grown, suggesting a future need for balancing services, such as manual Frequency Restoration Reserve (mFRR). A promising actor able to offer such balancing service is combined heat and power (CHP) plants due to their dispatchable power capabilities. This thesis aim
Objective: Emerging research suggests that rheumatoid arthritis (RA) is associated with intestinal dysbiosis. This prospective pilot study evaluates changes in intestinal microbial composition in patients with RA initiating treatment with either methotrexate (MTX) or a tumor necrosis factor inhibitor (TNFi). Methods: Consecutive patients, fulfilling the 2010 American College of Rheumatology/EULAR
Active pre-chamber configurations are considered a valuable solution for improving the operation of the internal combustion engine, in the view to overcome the many challenges it has been made to face. Combining this technology with the use of natural gas, a fuel that has increasing availability and interest in the market share, it is possible to burn ultra-lean mixtures (with air-to-fuel ratios,
Introduction Longer travel times are associated with increased adverse maternal and perinatal outcomes. Geospatial modelling has been increasingly used to estimate geographic proximity in emergency obstetric care. In this study, we aimed to assess the correlation between modelled and patient-reported travel times and to evaluate its clinical relevance. Methods Women who delivered by caesarean sect
In Sweden and elsewhere in the world the construction industry has encountered criticism due to its lower productivity gains in comparison to other industries. This is why continual improvement of processes and forms of cooperation are important, as is utilisation of technologies giving greater efficiencies. The focus in Sweden has mainly been on the construction of multifamily buildings, both bec
A new type of high-performance robots has been developed by ABB Robotics, the Robotics Lab at Lund University and Güdel AG, Switzerland. In all parts of the project, ranging from the simulation of the kinematic configuration and reachable workspace, and kinematic and dynamic calibration/grey-box identification, and to code generation of controllers and optimal switching strategies for hybrid contr
The student template in brief The student template in brief The first page in the template is a page you can use (make sure that page has no notes!) in the event of technical difficulties. If you are to publish your presentation on Canvas, the law requires you to make it accessible. Adapting for accessibility is important as it enables people with different abilities to participate fully. On the f
