Self-adaptive software systems monitor their operation and adapt when their requirements fail due to unexpected phenomena in their environment. This paper examines the case where the environment changes dynamically over time and the chosen adaptation has to take into account such changes. In control theory, this type of adaptation is known as Model Predictive Control and comes with a well-develope
The unnecessary and disproportionate use of pre-trial detention is a global issue that affects developed and developing countries alike. According to World Prison Brief, Cambodia has ranked 12th (among 217 countries) making it become a country with one of the highest percentages of pre-trial detainees: 71.8 percent to be exact. The excessive and unnecessary use of pre-trial detention in the Kingdo
Sverige har länge haft en hög andel förnybar energi och är ett av de medlemsländer i den Europeiska unionen (EU) som kommit längst i sin energiomställning. För att nå EU:s klimat- och energimål samt hantera ett förändrat geopolitiskt läge har det reviderade Förnybarhetsdirektivet, (RED III) antagits. Direktivet kräver att medlemsstaterna utser så kallade accelerationsområden där tillståndsförfaranSweden has for a long period of time obtained and maintained a high share of renewable energy and is one of the member states in the European union (EU) that has made the most progress in its energy transition. To meet the EU´s climate and energy targets and address a shifting geopolitical landscape, the EU has adopted the revised Renewable Energy Directive, (RED III). The directive requires membe
Elevators has for a long period of time been regarded as unsafe to use as a means of egress. This is an opinion that has shifted in the last couple of years as technical solutions has been found to the initial problems when using elevators as an escape route. This report investigates the possibility to replace a staircase with emergency elevators as a means of egress in a buildning. The report als
There is an urgent need to start generating energy within cities in order to pave the way for a more sustainable and resilient society. Renewable energy by means of active solar energy systems (solar thermal, ST and/or photovoltaics, PV) can be generated using roofs and facades of buildings. In this study, the annual solar energy potential of typical Swedish city blocks was analysed in order to de
We present a method to rapidly fabricate a large number of thermoplastic microfluidic systems where horizontal microchannels are separated by a porous membrane for modelling biological barriers. We optimize and combine solvent bonding, milling and laser cutting to fabricate in excess of 100 devices in two days. The optimized protocol relies on a commercial solvent blend, retention grooves for solv
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
This paper presents the characterization and optimization of acoustic capture of platelet-derived microparticles (PMPs) from human plasma. The technique is compared to a standard preparation protocol using differential centrifugation on biobank samples from patients with ST-elevation myocardial infarction (STEMI). The main advantages of this new method are the capability of rapidly capturing micro
Avhandlingen har titeln ”Konsten att upprätthålla löneskillnader mellan kvinnor och män” och är en rättssociologisk studie av vad som stått i vägen för likalöneprincipen, när internationella konventioner och EU-rätten medfört krav på förändringar av kollektivavtal och lagstiftning. Avhandlingens syfte har varit att undersöka och förstå hur löneskillnader mellan kvinnor och män skapas och återskapaThis dissertation, entitled “The Art of Preserving the Gender Pay Gap,” is a study in the sociology of law. It examines the obstructions to the principle of equal pay that persist in the face of international conventions and EU legislation that have mandated changes to legislation and collective bargaining agreements. The dissertation seeks to investigate and explain how the pay gap between women
Many ships today rely on Global Navigation Satellite Systems (GNSS), for their navigation, where GPS (Global Positioning System) is the most well-known. Unfortunately, the GNSS systems make the ships dependent on external systems, which can be malfunctioning, be jammed or be spoofed. There are today some proposed techniques where, e.g., bottom depth measurements are compared with known maps using
The emergence of new high brilliance and high coherence facilities such as X-ray Free Electron Lasers (XFELs) and 4th generation synchrotrons open a new era in X-ray optics. Dynamical diffraction effects before disregarded are starting to play a role in the beam control of large scale facilities. In the case of XFEL facilities the temporal characteristics of the dynamical diffraction by thin perfe
Structural Health Information (SHI) may be provided by various sources such as e.g. structural health monitoring, inspections, testing and digital technologies and networks as by the Industry Internet of Things (HOT). SHI holds a high potential for industrial, life safety and sustainability value and facilitates an optimal and intelligent life cycle management of infrastructure and machinery syste
BackgroundMajor depressive disorder (MDD) is associated with increased allostatic load (AL; a measure of physiological costs of repeated/chronic stress-responding) and metabolic dysregulation (MetD; a measure of metabolic health and precursor to many medical illnesses). Though AL and MetD are associated with poor somatic health outcomes, little is known regarding their relationship with antidepres
This paper reports simultaneous detection of ultra violet (UV) absorbance and native UV-excited fluorescence in an electrophoresis microchip using UV transparent integrated waveguides. Absorbance detection enables detection of a wide range of analytes. When exposed to UV light, some compounds also exhibit native fluorescence, which is here detected simultaneously. Calibration curves were measured
This paper presents an adaptive video encoder that can be used to compare the behavior of different adaptation strategies using multiple actuators to steer the encoder towards a global goal, composed of multiple conflicting objectives. A video camera produces frames that the encoder manipulates with the objective of matching some space requirement to fit a given communication channel. A second obj
This study explores the effectiveness of combining Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) for identifying internal erosion processes in embankment dams. A small-scale test dam was built in Älvkarleby, Sweden, with deliberately embedded but undisclosed defects to test monitoring capabilities. Daily ERT and IP measurements were collected during 4.5-year years, and anal
