In wildland fires, burning particles of vegetative material can be lofted by the fire plume and are subsequently transported horizontally by cross wind. Depending on the state of the firebrands (flaming, smoldering, inert hot, inert cold) upon landing they bear the potential to cause secondary fires. The present work introduces the reader to existing theoretical analyses of the problem of combusti
To meet national and international emission targets, the Swedish building sector needs to drastically reduce its carbon dioxide emissions, and to do so, a change in building techniques and materials is needed. Bio-based materials contribute to less emissions than conventional materials, like steel and concrete, but remain rather unknown to modern building sciences. This study aimed to increase kno To meet national and international emission targets, the Swedish building sector needs to drastically reduce its carbon dioxide emissions, and to do so, a change in building techniques and materials is needed.

The major driver of the climate and biodiversity crisis is our unsustainable production and consumption patterns, but the need to transition to a circular and resource- efficient economy has not been sufficiently addressed by policymakers. Policies supporting circular industrial transition are still rare, not the least in contrast with the recent momentum gained by green industrial policy in EU an
Existing studies on China’s COVID-19 response have gravitated to a macro-level,formal institutional analysis, focusing either on the effectiveness of the policy in early stage virus containment or on the growing negative impacts of COVID policy practices on China’s socio-political landscape at the late stage. Using serial interviewsaccompanied by online observations and documents, this thesis redi
Air pollution is a global health problem and in Mozambique, indoor air pollution is primarily causedby cooking over an open fire. This study examines the potential of coconut charcoal as a cleanercooking fuel and as a possible source of income for women in the village of Linga Linga, Mozambique.Previous research conducted in the village identified a need to investigate the willingness of thecommunAir pollution is a global health problem and in Mozambique, indoor air pollution is primarily caused by cooking over an open fire.

In this master's thesis a fully automated method is presented for seg-menting bones and cartilage in magnetic resonance imaging (MRI) of theknee. The knee joint is the most complex joint in the human body andsupports the weight of the whole body. This complexity and acute task ofthe knee joint leads to a disabling disease called Osteoarthritis among theadult population. The disease leads to loss o
The problems of de-blurring, de-noising, compression and segmentation are fundamental problems in image processing. Each of these problems can be formulated as a problem to find some approximation of an initial image. To find this approximation one needs to specify the approximation space and in what space the error between the image and its approximation should be calculated.Using the space of Bo
In this thesis, two emerging non-volatile memories, being the resistive random access memory and a ferroelectric capacitor were characterized at cryogenic temperatures. This was carried out due to the demand for non-volatile CMOS compatible cryogenic memories for quantum computing applications. Both devices exhibit good switching characteristics, endurance >10^7 cycles and multilevel capability. M
This masters thesis deals with mathematical signal detection in the field of NQR,Nuclear Quadrapole Resonance, which is a non-invasive spectroscopic technique usedto identify specific substances. The thesis has two main focuses, where the first isto propose novel methods for parameter estimation, especially for identification ofunknown signals. These extend the existing Capon and APES methods for
High humidity, high ash content and low heating values are the major disadvantages of using lignite without ant pretreatment. High moisture content and low energy density make some of the biomass resources disadvantages in direct energy production. In this thesis, the main aims to reduce the disadvantages of both sources and obtain fuel with different structural/physical properties by hydrothermal
The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines.To simulate the proton beam and for crea
Power electronic converters are pivotal while designing any charging scheme, regardless of the battery capacity and application. Nowadays, Power Factor Correction (PFC) converters have become popular for various battery charging systems due to their simple configurations. Single-Ended Primary-Inductor Converter (SEPIC) and Cuk PFC converters are preferred over buck-boost converters in this regard
Vehicle models are often bound by non-disclosure agreements with manufacturers.This thesis presents a vehicle model based on vehicle data gathered for the NationalAdvanced Driving Simulator in Ohio and therefore it is not bound by such limitationsand can be used in future research projects.The development and validation of the vehicle model requires understanding of thesubsystems studied, componen
Ready-to-eat (RTE) leafy greens offer an appealing way to integrate leafy greens into meals. Unfortunately, these leafy greens canget contaminated with human pathogens such as Salmonella, and Shiga toxin producing Escherichia coli (STEC) at any stage along themanufacturing chain, potentially leading to serious foodborne diseases. Currently, there is no single step in the production and processing
År 2045 har Sverige som mål att ha netto-noll utsläpp av växthusgaser. Från och med år 2019 betyder det att utsläppen måste minska med 6–10 % per år. År 2018 stod bygg- och fastighetssektorn i Sverige för 21 % av landets utsläpp av växthusgaser, vilket motsvarade 11,8 miljoner ton koldioxidekvivalenter. Om de utsläpp på 5,8 miljoner ton koldioxidekvivalenter som genererades på grund av import av s
Modern-day opportunities allow musicians to divert from normalised, widespread perceptions of their artistic needs and pursue diverse career paths. This thesis uses autoethnographic methods to explore a classical pianist's navigation between contrastingfields, such as international relations, higher education management, and music and performance.Artistic citizenship and discourse theory have been
This thesis presents a collation of two extant handwritings of the text Kitāb al-Ǧumal, a mystical treatise by the ninth century Sufi thinker Abū ʿAbd Allah Muḥammad ibn ʿAlī al-Tirmiḏī, also known al-Ḥakīm al-Tirmiḏī. The two handwritings are: (1) a manuscript from the Arabic collection at the Bibliothèque Nationale de France in Paris, comprising two and a half folios of relatively difficult to
Research on early postwar documentation efforts related to the Second World War and the Holocaust conducted by survivors of Nazi persecution has expanded over the past two decades. Yet, research on how knowledge circulatedtween these efforts – especially across various “borders” – is still nascent. This chapter seeks to gain a better understanding of the role of women’s informalworks during the ea
Poddcast "Öppet fall" från Lunds universitet, Juridiska fakulteten: Ett gift par som inte kan få egna barn beger sig till en fertilitetsklinik för att göra en provrörsbefruktning. Kvinnan vill sätta in två ägg men mannen går bara med på ett ägg. Trots det säger hon till kliniken att sätta in två ägg och blir gravid med tvillingar. Mannen accepterar inte att bli pappa till barnen eftersom han inte
