Finding vulnerabilities in open source software is an important part of software security. Software security is in turn a vital part in risk management and making risk assessments. The purpose of this thesis is to help organisations make decisions about vulnerabilities they have in their software programs by helping them make their own risk assessment. Our research uses the Common Vulnerability Sc
The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin. An alternative to these non-ren
The Internet of Things is coming. With it comes security challenges not present on common, more capable, devices such as desktop computers or servers. We argue that traditional channel security needs to be complemented with object security to cope with the constrained nature of small devices and Low Power Lossy Networks. The main reason for a partial transition to object security being heavy use o
This thesis mainly focuses on the protection strategies of microgrids for the Swedish power system in the medium voltage distribution system and specifically on the three-phase fault and earth faults protection strategies. For the analysis of both faults, different grid-connected, and islanding operations are simulated using DIgSILENT Power Factory. The simulation shows that using a distance prote
This paper explores the intersection of new urban spaces and new modalities of ‘homelessness’ in Japanese cities. We argue that the recent social phenomenon of “net café refugees” (netto kafe nanmin – people who substitute ‘manga cafes’ for their domestic residence) is conditioned by new forms of leisure, information technology, social manners, and the longterm contraction of the Japanese domestic
Supersymmetri (SUSY) är en av de teoretiskt bäst motiverade modellerna för fysik bortom standardmodellen (BSM), och en lovande kandidat för upptäckt vid Large Hadron Collider (LHC). ATLAS-kollaborationen har utfört omfattande sökningar efter SUSY-signaturer med hjälp av data från proton-proton kollisioner i LHC, tagna under 2010, 2011 och 2012 års tid vid energier på 7 TeV och mer nyligen 8 TeV. DSupersymmetry (SUSY) is one of the best theoretically motivated beyond the Standard Model (BSM) scenarios, and a favored candidate to be discovered by the experiments at the Large Hadron Collider (LHC). The ATLAS collaboration has been extensively searching for SUSY signatures using 2010, 2011 and 2012 data from LHC proton-proton collisions at a center-of-mass energy of 7 TeV and recently at 8 TeV
To guarantee that the products in the IKEA catalogue are available when requested, IKEA needs to plan and secure capacity. IKEA has developed a process called ONE Supplier Capacity Process to solve supplier capacity issues in a more proactive way. The thesis is focused on suppliers’ in the category Frames and Mirrors with frames in Greater China. Purpose The purposes of the thesis are fourfold: •
The main purpose of this thesis is to describe different numerical methods for solving the time-dependent Schr¨odinger equation. We introduce and describe two different basis representations (spectral and pseudospectral). These basis representations are then used in the different methods we take up for discussion. We consider methods in which the Hamiltonian is constructed in a spectral basis and
When experience is insufficient or not present at all, making decisions becomes difficult. Capability assessments are tools to inform decisions in all situations regarding risk management, but the use of them in Sweden is discussed. With experiments made in the microworld MikroRisk, conclusions can be made about the investment patterns induced by a capability assessment under the conditions of bot
A search for the lepton-flavor violating decays Bs0→φμ±τ is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9 fb-1. The τ leptons are selected using decays with three charged pions. No significant excess is observed, and an upper limit on the branching fracti
This chapter explores the evolution and effectiveness of Sweden's climate policy mix for decarbonizing the transport sector—a major contributor to national greenhouse gas (GHG) emissions. Despite early leadership in climate policy, Sweden faces challenges in aligning policy implementation with ambitious goals, such as a 70 % reduction in transport emissions by 2030. The chapter shows that Sweden's
This paper is concerned with the numerical computation of the Titchmarsh-Weyl M matrix. We show how an algorithm may be developed which relates solutions of an initial-value problem to an approximation of the M matrix. In some special cases we compare the results from our algorithm with results obtained using special functions.
In digital control systems, the state is sampled at given sampling instants and the input is kept constant between two consecutive instants. With the optimal sampling problem, we mean the selection of sampling instants and control inputs, such that a given function of the state and input is minimized. In this paper, we formulate the optimal sampling problem and we derive a necessary condition of t
The activated sludge process is the main process in most urban wastewater treatment systems. It is considered complex in nature, and building its mathematical model in practice becomes difficult. A simple and easy way to build the simulation models for the system is needed. In this paper, a LabVIEW based simulator for the system is presented. LabVIEW offers a highly efficient, simple and flexible
