In this thesis, we address three main security problems related to cryptography andcloud storage. To tackle the challenge posed by a quantum computer, we needencryption that is resistant to quantum computers. This category of cryptographyis called post-quantum cryptography. In the first paper, we solve a challengein one of the lattice-based cryptographic protocols called Nth-degree Truncatedpolyno
Microplastic (MP) pollution is increasingly recognized as a critical issue in coastal environments, where complex interactions between ocean currents, winds, waves, and human activities govern the transport and deposition of synthetic particles. Although previous studies in Asia have documented MPs accumulation linked to riverine discharge, tourism pressures, and monsoonal circulation, limited wor
Purpose: The aim of this study was to assess the suitability of Gafchromic EBT3 films for reference dose measurements in the beam of a prototype high dose-per-pulse linear accelerator (linac), capable of delivering electron beams with a mean dose-rate (Dm) ranging from 0.07 to 3000 Gy/s and a dose-rate in pulse (Dp) of up to 8 × 106 Gy/s. To do this, we evaluated the overall uncertainties in EBT3
Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS. One drawback of the existing
Context. Ultra-hot Jupiters present a unique opportunity to understand the physics and chemistry of planets, their atmospheres, and interiors at extreme conditions. WASP-12 b stands out as an archetype of this class of exoplanets, with a close-in orbit around its star that results in intense stellar irradiation and tidal effects. Aims. The goals are to measure the planet's tidal deformation, atmos
Popular Abstract in Swedish Nästa år är det 400 år sedan Galileo Galilei för första gången riktade ett teleskop mot objekt på himlen. Allt sedan dess har teleskopet varit det viktigaste instrumentet för astronomins utveckling och med dess hjälp har vår kunskap om universum revolutionerats. Tack vare utvecklingen av teleskopet under dessa århundraden har allt ljussvagare objekt kunnat studeras, ochThis thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. The aim of this project was to gain hands-on knowledge in the development of a real adaptive optics system and eventua
Popular Abstract in English Jordan is a country with a rapidly growing economy, modernization and growing population. The rapid increase in volumes of solid wastes and a steady increase in the cost and logistical difficulties with the associated risk to human health is a source of concern. The increasing solid waste generated in Jordan has not been accompanied with adequate sanitation facilities aJordan is a country with a growing population that is undergoing rapid modernization. The increased volume of solid waste and associated logistical difficulties, the steady growth in the cost of waste management and the risk to human health are sources of concern. The increasing amount of solid waste generated in Jordan has not been accompanied by adequate sanitation facilities or management progr
Bygg kabelkonstruktioner i trä! I dagens samhälle blir det allt viktigare med hållbara lösningar för att lyckas bromsa den globala uppvärmningen. Stål och betong står båda för stora klimatutsläpp och har efter industrialiseringen varit det dominerande valet av material för stora byggnader. Ett alternativt, hållbart material som lyfts fram att kunna vara framtidens material är trä. Ett exempel på eIn the design of a building there are many parameters that effect the material efficiency. The choice of structural solution and material are two of the parameters that will be investigated further in this rapport. Suspension structures is one type of structural solution that has high material efficiency, here the bending stiff properties of timber could also be utilized in order to increase the s
Uppsatsen behandlar svenska internationella privat- och processrättsliga (IP-rätt) frågor rörande den svenska kollektiva arbetsrätten, varmed förstås den relation mellan arbetsgivare och fackförening samt de tvister som därur kan uppstå. Huvudfrågorna är de som traditionellt anses utgöra den IP-rättsliga problematiken, vilka utgörs av jurisdiktionsfrågan, lagvalsfrågan och verkställighetsfrågan. JThis thesis addresses a private international law perspective of questions and problems related to cross-border collective labour law disputes in Sweden. This means, in Swedish terminology1, that the researched issues are the questions of jurisdiction, choice of law and enforceability in disputes arising from the relation between an employer and a workers' union. Collective labour law in Swede
Sammanfattning Instansordningsprincipen är en förvaltningsrättslig princip som huvudsakligen medför att parterna i ett förvaltningsmål är förhindrade att tillföra nytt processmaterial i högre instanser. Principen är, emellertid, inte uttryckligen lagstadgad i Förvaltningsprocesslagen (1971:291), FPL. Istället är det upp till förvaltningsdomstolarna att tolka de uttalande som finns i förarbetena tiSummary The principle of the court hierachy is a principle within administrative law whose intention is to prevent the parties to add new case material in the higher instances. The principle, however, is not explicitly stated in the Administrative Court Procedure Act (1971: 291), FPL. Instead, the administrative courts are given the task to interpret various statements contained in the legislative
The Philippines is an island nation in South East Asia consisting of more than 7 000 separate islands. The Philippines is the country in the world that is most often struck by tropical storm; every year between 6 and 9 typhoons hit land in the Philippines. In November 2013 the super typhoon Haiyan hit the nation, killing 10 000 people and causing massive destruction to parts of the infrastructure
In this project the aim was to design a concrete 3d printer. This report focuses on the extruder part of the printer and the printing material. The basic principle of 3d printing is that it is an additive manufacturing technique, on the contrary to the traditional subtractive manufacturing techniques. The potential benefits of concrete 3d printing compared to the techniques that are used today are
Urbaniseringen innebär att det blir mer och mer hårdgjorda ytor i städer, vilket ökar belastningen på dagvattennätet. Vidare så innebär klimatförändringarna ytterligare utmaningar då nederbörden i Sverige antas öka. För att hantera detta föreslås hållbara dagvattenlösningar varav gröna tak kan vara en del. Detta skapar ett behov att på ett enkelt sätt modellera avrinningen från gröna tak. I detta

In fact, AB Svenska Spel and Oddset are calculated to possess only 6-7% of the Swedish live-betting market and at the same time a considerable part of the unregulated foreign bookmakers turn
Main title: Trading-intense housing environments. City centers tend to condense – these pieces of land are attractive for many different purposes. Co-using of buildings becomes more and more usual. For instance there are on-going investigations regarding how to create attractive residential environments close to shopping areas with high traffic density. In many places, the vision is a mixed-use ne
This thesis describes experiments involving laser-plasma-based acceleration of electrons and protons, using the techniques of laser wakefield acceleration (LWFA) and target normal sheath acceleration (TNSA). By using extremely high accelerating field strengths, up to the order of TV m-1, it is possible to reach high kinetic particle energies over very short distances.The multi-terawatt laser syste
Irradiating a flame via microwave radiation is a plasma-assisted combustion (PAC) technology that can be used to modify the combustion chemical kinetics in order to improve flame stability and to delay lean blow-out. One practical implication is that combustion engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. Furthermore,
