This master thesis covers the process followed in the re-design and optimization of a structural part in a supercar. The part reviewed is the Rear Cross Frame currently in production of all Koenigsegg’s supercars. In the new revision of the part, the material is Carbon Fiber. The version currently in production is made of steel. The shape has been modified to fit the Carbon Fiber manufacturing req
Syfte: Studien undersöker om det på ett reliabelt sätt går att använda en modifierad version av Pati-ent Attachment to Therapist Rating Scale (PAT-RS) för att skatta anknytningsmönster från patient till terapeut utifrån inspelade psykoterapisessioner från fjärde sessionen under en korttidsterapi. Metod: Två oberoende observatörer har skattat anknytningsmönster från patient till terapeut utifrån 30Objective: This thesis investigates if it is possible to use a modified version of Patient Attachment to Therapist Rating Scale (PAT-RS) estimating attachment style between patient and therapist dur- ing an early stage of short term psychotherapy in a reliable way using recorded psychotherapy ses- sions. Method: Recorded material from 30 psychotherapy sessions have been separately estimated by two
This research tests two different focus groups with the purpose of developing quantitative online surveys suitable for a specific target group. Depending on where in the development process of the survey the researcher is, somewhat different focus groups should be used. If the researcher is far into the development of the survey a focus group with the questionnaire template as discussion basis cou
This research examines how focus groups can be used as a tool for designing quantitative online surveys suitable for a specific target group. Depending on where in the development process of the survey the researcher is, somewhat different focus groups should be used. If the researcher is far into the development of the survey a focus group with the questionnaire template as discussion basis could
The purpose of the study is to see if International Accounting Standards for Small and Medium sized entities are suitable for entities in Macedonia, with the emphasis on accounting quality. This thesis has an inductive approach. A qualitative method was selected as a strategy and semi-structured interviews were conducted in order to gather relevant information from the respondent. Hereto, we concl
Biopolymers are interesting materials from a sustainable point of view. Especially since consumers increasingly demand environmental friendly packages as well as more convenient packages with easy open and close features on the packages. The demands for convenient packages lead to more and more plastics in the packaging industry. The purpose with this project is to find out typical properties of
In this study, a synthesis process based on the microemulsion method (ME) was developed with the aim to produce controlled-size starch nanoparticles (SNPs). Several formulations were tested for the preparation of the W/O microemulsions varying the organic/aqueous phase ratios and co-stabilizers concentrations. SNPs were characterized in terms of size, morphology, monodispersity and crystallinity.
We introduce an improvement to the FxFx matrix element merging procedure for pp →tt¯ W production at NLO in QCD with one and/or two additional jets. The main modification is an improved treatment of jets that are not logarithmically enhanced in the low transverse-momentum regime. We provide predictions for the inclusive cross section and the tt¯ W differential distributions including parton-shower
Oxidation of SO2.nH2O/HSO3-/SO32- by Pt(CN)4Cl22- has been studied at 25-degrees-C and 1.0 M ionic strength in acidic aqueous solution by use of stopped-flow spectrophotometry. The stoichiometry of the reaction is 1:1 according to Pt(CN)4Cl22- + HSO3 + H2O --> Pt(CN)42- + 2Cl- + HSO4- + 2H+. It is first-order with respect to both [Pt(IV)] and [S(IV)]. The pH-dependence in the region 0.3 < pH < 4.5
The group of small poor cods and pouts from the genus Trisopterus, belonging to the Gadidae family, comprises four described benthopelagic species that occur across the North-eastern Atlantic, from the Baltic Sea to the coast of Morocco, and the Mediterranean. Here, we combined molecular data from mitochondrial (cytochrome b) and nuclear (rhodopsin) genes to confirm the taxonomic status of the des
Listeners are constantly trying to predict what the speaker will say next. We concurrently measured the electrophysiological and haemodynamic correlates of syntactic pre-activation, investigating when and where the brain processes speech melody cues to upcoming word order structure. Pre-activation of syntactic structure was reflected in a left-lateralised pre-activation negativity (PrAN), which was
Carbon dioxide expanded liquids (CXLs) is a relatively recent type of solvent used in separation processes such as extraction. It combines the benefits of high solubility in the organic liquid with enhanced mass transfer mediated by the compressed CO2. In this work, we investigate the solubility of curcumin in CO2-expanded ethanol and for this purpose an equipment setup was built and used for expe
A low-cost microstrip patch antenna array is proposed in this paper for automotive radar applications in ISM 24 GHz band. The elements of the center-fed array are connected in series to make a compact design with low complexity by obviating Wilkinson power divider. This approach also helps to reduce the dielectric losses of the array. A full-wave electromagnetics (EM) software EMPIRE XPU is used i
An LTE-enabled smartphone is a software-defined radio system that must cover a large number of frequency bands with different duplex differences. A proposed adaptive wideband duplexer needs a circulator to create the required initial isolation. To replace this an LC-based tunable low-isolation device is presented in this paper, providing the required tuning range for LTE Band I, II, III and VII. T
Popular Abstract in Swedish Beräkningar av högre ordning i kiral störningsteorin med tre kvarkar presenteras. De relevanta frihetsgraderna i denna teorin är de lättaste pseudo-skalära mesonerna, pionen och kaonen. Syftet med dessa beräkningar är dubbelt. För det första, att kunna bestämma de erforderliga lågenergi-konstanter som krävs för att uppnå högre precision i förutsägelserna från denna teorHigher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. Secondly, testing the validity of the chiral expansion in the strange quark mass, with emphasis on the valu
Influence of sintering temperature on both phase composition and structure of ceramic matrix composites based on cubic boron nitride with binders in a form of Al and the Ti, Cr, V carbides are investigated by methods of physical materials science. As the object of study, three cBN–TiC–Al, cBN–Cr3C2–Al, cBN–VC–Al compositions containing 60% vol. cBN are selected. The composites are obtained by high
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into biorefineries they can be a keystone in a future bioeconomy based on renewable resources instead of fossil fuels. In order to achieve this, pulp mills have to close their loops
This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the
