Evacuation models can be reliably used if they are sufficiently validated for the application in question (e.g. Fire Safety Engineering). To be useful, an evacuation model should therefore be an accurate enough representation of the real-world behaviour of evacuees. The scope of this work was to determine how accurately the model crowd:it (making use of the Optimal Steps Model) provides a represen
Molecular imprinting technology is a field where polymer technology is utilised to synthesise high affinity particles, much like antibodies. This project has dealt with the imprinting of the neurotransmitter molecules serotonin and histamine. Serotonin polymers were synthesised using methacrylic acid and acrylamide as functional monomers relying on hydrogen bonding for the imprinting effect. None
Syftet med mitt master projekt i industriell design vid IKDC var att utveckla och uppgradera produkten trygghetslarm. Detta larm skall kunna göra det möjligt för äldre och rörelsehindrade att bo kvar i hemmiljön, med tryggad kontakt till hemtjänsten när olyckan är framme. Bakgrunden till valet av projekt är bland annat personliga skäl, då trygghetslarm varit livsavgörande för några av mina släktin
The road haulage industry is a fundamental part of today’s society. The companies of haulage stand before a challenge, as the environmental and economic sustainability demands are increasing. The automotive industry tries to meet these demands by developing intelligent systems that will decrease the fuel consumption. The two systems, predictive controller and platooning, are two intelligent solut
Huvudsyftet med denna rapport är att förutsäga antalet spelare i nå- gon instans av DICE: s spelplattformar, t.ex. Battlefield 3 för PC, 15 minuter i framtiden. Denna förutsägelse kan användas av företaget vid köp av molnservrar on-demand för att visa dem hur mycket de behöver köpa. Flera olika prognosmodeller undersöks och utvärderas på historisk data från 2011 till 2015. En annan fokuspunkt är hThe main goal of this thesis is to predict the number of players in some instance of DICE’s gaming platforms, e.g. Battlefield 3 for PC, 15 minutes in the future. This prediction may be used by the company when buying on-demand cloud servers to tell them how much they need to buy. Several different prediction models are examined and evaluated on historical data from 2011 to 2015. Another focus poi
In the last couple of years it has become more and more common to use control theory in computing systems, for instance operating systems, web servers and databases. The reason for this is to make these systems more robust and stable. This is of interest because we today are more dependent on computing systems in our everyday life, and therefore put higher demands on them. A lot of focus has been
In this report we study systems governed by the Saint-Venant shallow water equations interacting with boundary conditions including control. We derive closed form formulas for the open-loop behavior. These formulas rely on first, second and third order approximations which are based on a perturbation that we develop. Properties of these solutions are studied and comparisons with existing non-linea
Background The EU’s 20-20-20 targets determine that Finland’s share of energy consumption from renewable energy sources is to be 38 % by 2020, a target that the government intends to reach by expansion of wind power. The government has a beneficial feed-in tariff in place as an incentive for rapid wind power expansion, which has made both domestic and international developers evaluate the business
Resultatet av studien visar att det finns komparativa skillnader på tre olika nivåer. (1) På den nationella nivån framhålls den för arbetstagaren extensiva svenska arbetsrätten och den generösa sjukförsäkringen som potentiella orsaker till att sjukfrånvaron är högre i Sverige än i Danmark. (2) På den organisatoriska nivån konkluderas att de svenska organisationerna har starkare tonvikt på hälsa oc
The study aims to explore the relationship between migration and the quality of education, considering the lowering quality of higher education in Georgia as one of the main ‘push-factors’. The research itself tries to identify the main motivations of why Georgian students migrate. Furthermore, the main gaps and disadvantages of the higher education system of Georgia are investigated. The findings
This dissertation utilizes a new dataset on the belongings of early modern households, gathered from southern Sweden, to map the development of wealth and material living standards over the course of the early modern period. Together, the four papers making up the main part of the dissertation depicts a significantly more economically dynamic early modern period – especially eighteenth century – tThis dissertation utilizes a new dataset on the belongings of early modern households, gathered from southern Sweden, to map the development of wealth and material living standards over the course of the early modern period.

Neural firing rates are thought to represent values which code information. There are drawbacks with using biophysical events to represent numbers. (1) Rate code (like any sequence) is inherently slow to read. (2) At short intervals, the code becomes unintelligible biophysical noise. (3) Transmission times. The vital contribution of the cerebellum to skilled execution and coordination of movements
The Restricted Syndrome Decoding Problem (RSDP) is a variant of the well-known syndrome decoding problem. It has been recently turned into a post-quantum signature scheme named CROSS by Baldi et al.. It is a scheme highlighted for being computationally friendly and providing a compact signature and public key size. This paper investigates an Oracle-based definition of the RSDP that has already pro
We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method for detecting the entanglement dimensionality through certification of the Schmidt number. Its key feature is that the computational cost is independent of the Schmidt number under consideration. Secondly, we provide a m
Pancreatic ductal adenocarcinoma has one of the worst survival rates among adult cancers, with only 11% in the United States surviving five years after diagnosis. The majority of patients are diagnosed with late-stage disease, since early-stage pancreatic ductal adenocarcinoma is typically either asymptomatic or presents with non-specific symptoms. Pancreatic ductal adenocarcinoma thus remains a h
In this concluding chapter, we draw together the threads of the different assessments carried out by the contributors and propose directions for future research. After a brief overview of the content of the chapters, we revisit and complicate the initial taxonomy we offered, attempting to suggest instead a more abstract classification that could serve as a basis for future assessments. Moreover, w
The clinical commissioning of beams for neutron capture therapy involves the measurement and analysis of a large amount of data in various geometries and using various detectors. We have attempted methods and considerations common to the radiotherapy field, while particular care and attention is given to the specifics of the field of neutron capture therapy. This chapter provides an introduction a
BACKGROUND: The tau-PET radiotracer [18F]flortaucipir enables in vivo detection of tau pathology in Alzheimer's Disease (AD) and has recently been FDA- and EMA-approved for clinical use. To support its implementation, we assessed tau-PET's positive predictive value (PPV) and negative predictive value (NPV) for clinico-pathological AD while accounting for age, amyloid-status, and pre-PET diagnostic
The T-REX neutron spectrometer at the European Spallation Source will use Multi-Grid Technology, which is a voxelised proportional counter relying on 10B4C coatings to detect neutrons scattered by the sample under investigation. Measurements of the position dependence of pulse-height and relative detection efficiency of a Multi-Grid prototype of the T-REX spectrometer are presented for two differe
