Cell reprogramming technologies have enabled the generation of various specific cell types including neurons from readily accessible patient cells, such as skin fibroblasts, providing an intriguing novel cell source for autologous cell transplantation. However, cell transplantation faces several difficult hurdles such as cell production and purification, long-term survival, and functional integrat

Ontology organizes and formally conceptualizes information in a knowledge domain with a controlled vocabulary having defined terms and relationships between them. Several ontologies have been used to annotate numerous databases in biology and medicine. Due to their unambiguous nature, ontological annotations facilitate systematic description and data organization, data integration and mining, patt

The present study describes the development and testing of a tool for dolphin research. This tool was able to visualize the dolphin echolocation signals as well as function as an acoustically operated “touch screen”. The system consisted of a matrix of hydrophones attached to a semi-transparent screen, which was lowered in front of an underwater acrylic panel in a dolphin pool. When a dolphin aime

Presumed effects of global warming on occupational heat stress aggravate conditions in many parts of the world, in particular in developing countries. In order to assess and evaluate conditions, heat stress must be described and measured correctly.

Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. Wired BMIs are limited in the sense that they restrict the mobility of the subject and they increase the risks for post-surgical co

We had in the present thesis the unique possibility to use, in a socio-economically relatively homogenous population, high quality registry information on a population-based birth cohort (84 039 births during the period 1999-2005) in Scania (Skåne), the most Southern county of Sweden. The aim of the thesis was to investigate whether exposure to air pollution, in an area of low-levels exposures, du

Background: Sharing of data about variation and the associated phenotypes is a critical need, yet variant information can be arbitrarily complex, making a single standard vocabulary elusive and re-formatting difficult. Complex standards have proven too time-consuming to implement. Results: The GEN2PHEN project addressed these difficulties by developing a comprehensive data model for capturing biom

In the realm of wireless communications, the exploration of user equipment (UE) sensing capabilities has emerged as a complementary approach for optimizing the performance of wireless networks. This thesis delves into the potential enhancements achievable by integrating UE sensing capabilities into wireless networks, focusing on detecting Line Of Sight (LOS) and Non Line Of Sight (NLOS) scenarios.

Abstract The principle of fiscal neutrality is at the core of the EU VAT system. Neutrality in the EU VAT system comprises of two main elements, that is, equal treatment of taxable persons in the same situation and giving taxable persons the right to deduct input VAT for cost components. The right to deduction is an important element of the VAT system to achieve fiscal neutrality. Deductibility en

The average Swede uses 140 liters of water everyday. This combined with the usage in industry means that Swedish municipal water treatment plants produce approximately 900 billion liters of clean and safe drinking water every year. This does not include the fact that all water flowing to a treatment plant needs to be treated before being sent back out into the environment. These facts hint at what

Artificial neural networks (ANNs) are widely used nowadays, and the research into improving their performances is continually ongoing. One main goal of ANNs is to have a high generalization performance, which can be estimated through validation. Ensembles can be useful to raise the generalization performance, but the validation of ensembles is often computationally costly if the size of the traini

In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. We use Pythia and Delphes for event generations and detector simulations, and consider both pp and e+e− collision events at 13 TeV. The kinematic studies are based

This paper examines export diversification with main focus on the Economic Community of West African States (ECOWAS), a union promoting economic integration in the region of West Africa. The West African Economic and Monetary Union (WAEMU), another Regional Integration Agreement (RIA), is also of main importance for the study. The study was conducted in order to determine whether ECOWAS and WAEMU,

This project investigates the needs of different stakeholders regarding volunteer work in Sweden as well as implementing a prototype for a volunteer app. The main purpose is to design, create and test a mobile application prototype primarily focused on the end users, the volunteers. This is done by accumulating a lot of data and information using a survey that reached out to 111 volunteers and non

This thesis was performed in collaboration with Phoniro AB, that develops digitally unlocked products that are mainly used in home care service. The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuri

Stroke affects a vast amount of people every year. As a result, many survivors have at least partially lost some of their abilities which are necessary to complete everyday activities. Although rehabilitation can be used to improve those abilities, many survivors claim that conventional methods are demotivating and discouraging. The aim of this project is to develop and test interactive objects, w

In recent years, with corporate scandals and the global financial crisis there is continuous attention in the area of corporate governance which is the new concept in corporate world these days. It is seen as a moral duty and includes supporting the conformity to law and showing ethical guide. Corporate Governance is seen as a significant tool as firms’ financial performance when investors take an

In process industry many control loops are far from optimally tuned. In this master's thesis a tool for rapid process identification and control design has been developed. The tool, which is implemented in Matlab 5.3, identifies a process model out of the step response of the real process. A PI or PID controller can then be designed and evaluated. The tool contains three different automatic de
