Körfältsbreddens påverkan på bussars framkomlighet

Kollektivtrafiken spelar en central roll i ett hållbart transportsystem, särskilt när det gäller att uppnå globala hållbarhetsmål och nationella transportpolitiska mål. I täta stadsmiljöer leder begränsat gatutrymme till konkurrens mellan olika transportmedel, såsom mellan cykelbanor, gatuparkering och dedikerad bussinfrastruktur. En viktig faktor som påverkar bussars framkomlighet är körfältsbredPublic transport plays a key role in creating sustainable urban transport systems, particularly in meeting global sustainability targets and national transport policy goals. In dense urban environments limited street space leads to competition between different modes of transport such as between cycle lanes, on-street parking, and dedicated bus infrastructure. One important factor affecting bus ma

Underhållsstandard i kommuner - Initiering av underhållsåtgärder

Denna uppsats undersöker vilka skadetyper från skadeinventeringar som initierar underhåll, samt hur väl Trafikverkets riktlinjer för spårdjup och IRI (International Roughness Index), som vanligtvis används på nationella vägar, speglar underhållsbehov i kommuner. Malmö, Sveriges tredje största stad, förvaltar ett omfattande vägnät på cirka 100 mil, där cirka 3 % årligen underhålls eller byts ut, inThis thesis investigates which damage types in condition surveys trigger maintenance and how well the Swedish Transport Administration’s standards for rut depth and IRI (International Roughness Index), typically used on national roads, reflect maintenance needs in municipalities. Malmö, Sweden’s third-largest city, maintains an extensive road network of about 1000 kilometers, with 3% repaired or r

Cirkulära anläggningsmaterial - Undersökning av sekundära ballastmaterial inom anläggningsbranschen genom upprättandet av testväg

Vid byggnation av vägar och järnvägar i Sverige idag används nästan uteslutande ändliga resurser som bergkross eller naturgrus som ballastmaterial. Det är av stort intresse att undersöka om till exempel återvunnet material och restprodukter från industrier skulle kunna användas i stället. För detta ändamål byggdes en testväg i november 2024 inne på en avfallsanläggning i Helsingborg. Vägen, som foDuring construction of roads and railways in Sweden today, mainly finite resources such as crushed rock or natural gravel, are being used as ballast material. It is of great interest to investigate whether, for instance, recycled materials and residual products from industries could be used instead. For this purpose, a test road was constructed in November of 2024 in a waste facility in Helsingbor

Off-Shell Recursion with Orthogonal Multiplet Bases for Computing Gluon Amplitudes

När två protoner, accelererade till nära ljusets hastighet, krockar i den 27 km långa partikelacceleratorn under den fransk-schweiziska gränsen vid CERN, världens centrum för partikelfysik, så bildas dussintals energetiska sub-atomära partiklar. Den vanligaste partikeln som bildas kallas för gluon, efter engelskans "glue" som betyder lim. Detta namn har den fått eftersom den fungerar somCalculating the color factor of matrix elements for gluon processes is difficult since the gauge group of QCD, SU(3), is non-Abelian. The most commonly used methods for treating color structure all scale as the square of a factorial with the number of gluons, making calculations with more than a few gluons too time-consuming to carry out on demand. This thesis will provide an alternative approach

On the resolution to Tsirelson's problem

Correlations between two quantum agents, Alice and Bob, are typically modeled by assigning each a separate Hilbert space and representing their joint system as a tensor product of these spaces. Alternatively, one can let Alice and Bob act on a single Hilbert space, and require that their measurement operators commute. Tsirelson's problem asks whether any such commuting correlation can be appro

Exhaled breath particles as a diagnostic tool for bronchiolitis obliterans syndrome in lung transplant recipients: a longitudinal study

Background: Long-term survival after lung transplantation is significantly shorter compared with other solid organ transplantations. Chronic lung allograft dysfunction (CLAD), including bronchiolitis obliterans syndrome (BOS), remains the major barrier to survival. CLAD is diagnosed according to ISHLT's guidelines: a 20% drop in FEV1 using spirometry for CLAD grade 1. Given the difficulties of con

Ephemeral space sanctification and trespassing gender boundaries in a Muslim city

A distinct feature of Muslim cities is demarcated separation between zones of public economic and private domestic activities. Such spatial distinction has been the organic extension of a social structure with limited presence of women in public zones. However, separation of spaces in the Muslim city and the way it is utilized, shaped and reproduced by men and women is not a simple case of dividin

Design, Integration, and Multiphase Modeling of Phase Change Material (PCM) for Thermal Management of BEV Inverter

With the rapid advancement of electromobility sector, the power density and heat generation of electronic chips is significantly rising. Due to its higher load and lower thermal mass, electronics chips in BEV inverters, such as MOSFETs, are increasingly susceptible to rapid temperature rises. Through the utilization of latent heat absorption, Phase Change Material (PCM) offers a promising passive

Purification of the Hylobius abietis TRPA1 ion channel

Hylobius abietis is a common pest in the forestry industry, damaging countless of conifer seedlings each year. By solving the structure of the nociceptor, HaTRPA1, a repellent could be developed to replace environmentally dangerous pesticides. To solve the structure, a large amount needs to be purified. Previous problems plaguing previous studies include low protein yield and contamination from Co

The water sensitive future of Lahijan

The emergence of the modern urban water system in Iran, albeit facilitated access to clean water and accelerated discharge of waste- and stormwater, it left some negative imprints on country’s urban and natural environment. Among which larger stress on natural water cycles and pollution of water resources are of great importance. More importantly, such impacts are occurring when cities are going t
