Capacity shortages in electricity grids can impose significant costs on society due to missed investments in industry. Due to limited profit opportunities and long lead times, grid reinforcements are not a viable solution to the problem, which must therefore be prevented through efficient use of existing grid resources. Local flexibility markets can financially compensate electricity users to shif
Cold attics are a common element present in the Swedish residential building stock. They are known to be prone to mould problems due to their low ventilation and are one of the main channels through which buildings lose heat. One of the strategies that can help solve cold attic problems and at the same time contribute to solving the housing crisis is their conversion into habitable spaces. This re
Predicting the next location of human mobility and its semantic information can support recommendations for location-based services and trajectory mining, such as human mobility pattern recognition and sequential anomaly detection. Previous studies have ignored the implicit correlation between location and spatiotemporal information thereby limiting the model performance in terms of location predi
The increased competition caused by the global economy we are facing has forced companies to develop well established corporate strategies. Merging or acquiring a company has for a long time been used by organizations as one of the main strategic tools for expanding globally or for entering new markets. The problem is that over 50 percent of the Mergers and Acquisitions (M&A) fail by deliverin
Social work is often described as a moral practice. In human service organisations social workers have room to evaluate and judge people with social problems. Thus, social work assumes processes of categorization and preconceptions of clients. These processes could have the consequence that client's individual characteristics are overlooked in favor of properties associated with the category t
Who cares about the people with a gambling abuse? Gambling abuse is a problem that has been getting more and more attention in the media and through the people that work with the subject. The Swedish state has monopoly on gambling in Sweden but the Internet makes it possible for international gambling companies to reach customers in Sweden. This in return makes it harder for the Swedish state and
This study focuses on the human factors associated with elevator use during evacuation in residential buildings. An online survey is conducted to explore seven factors that may influence people’s choice of elevators in China and the United Kingdom, including floor height, waiting time for elevators, crowd density in front of elevators, mobility limitations, instructions, fire location concerning p
Bus Rapid Transit, in short BRT, is a transport mode that has the potential to support a modal shift. In Sweden, there has been a growing interest in BRT, particularly in smaller to medium-sized cities. The challenge lies in the absence of a clear definition of how this kind of system should be designed in a Swedish context. Consequently, there have been efforts to create guidelines and assessment
In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. Consideration must be given to whether compromised security is an unavoidable effect of instant payments or if both obj
Abstract in Danish Nytter rollatorer og elkørestole? Mennesker med gangbesvær kan opleve manglende muligheder for at udføre aktiviteter, som er forudsætningen for at leve et godt liv og deltage i samfundslivet på lige fod med andre borgere. Desuden vil nedsat mobilitet føre til inaktivitet, der har helbredsmæssige konsekvenser. Derfor sættes der fra samfundets side ind med rehabilitering, blandt Rollator and powered wheelchair interventions are often applied to make participation possible for citizens with limited walking capacity. However, the research-based knowledge about outcomes is insufficient for societal prioritisation purposes and for quality development of assistive technology within occupational therapy contexts. In this thesis outcomes in terms of user satisfaction, participat
A microwave-assisted extraction (MAE) method has been developed for determination of zearalenone in wheat and corn by LC-MS with an atmospheric pressure chemical ionization interface (APCI). Matrix effects were minimized by use of matrix-matched standard curves for quantification of the analyte. The limit of quantification (LOQ) of the method was 30 ng g(-1) in wheat and 20 ng g(-1) in corn. The r
Background. Decompressive craniectomy (DC) is an option for the treatment of increased intracranial pressure resulting from an acute neurological insult, including insults caused by trauma. When the brain swelling has receded, the skull is reconstructed with a wide choice of materials, each with its own advantages and disadvantages in terms of cost, cosmetic appearance, biocompatibility, implant s
A positive relationship between daily physical activity and aerobic fitness exists in adults. Studies in children have given conflicting results, possibly because of differences in methods used to assess daily physical activity and fitness. No study regarding daily physical activity and fitness in children has been published, where fitness has been assessed by direct measurement of maximum oxygen
Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. The adaptive behaviour of the involved microorganisms imposes further difficulties in terms of time-varying process parameters. Mathematical models and computer simulation
E-GIS is a Leonardo pilot project, within Geographical Information Science (GIS), to be implemented over a three year period, 2002-05. The main objectives of the project is to establish co-operation between European Universities and GIS user organisations and to develop modularised courses intended for Internet based learning, establish links of communications between the partners in the project i
Background: Reported improvements in outcome in stroke patients treated in hospital are often attributed to advances in stroke care. However, secular trends in patient characteristics that are present already on admission to hospital may also contribute to improved outcome. Methods: Time trends for baseline data (289,854 stroke admittances) in Riks-Stroke, the Swedish national quality register for
Objective - To investigate the feasibility of monophasic action potential ( MAP) mapping using an electro-anatomical mapping system ( CARTO) in obtaining information on global dispersion of atrial repolarization and to evaluate the role of dispersion of repolarization in the genesis of paroxysmal atrial fibrillation ( PAF). Methods and results - Right atrial MAPs were recorded from 53 +/- 18 sites
