The aim of the thesis was to build a test environment to be used by the company Cactus Uniview. The test environment should be a tool (software) for testers in the development department, the test environment should be able to ensure the quality of the tool Cactus Eye. Cactus Eye is connected to a PLCs and can be used to control many PLCs. Cactus Uniview uses a virtual test environment (entirely b
En liten molekyl med en stor uppgift Alla människor ser olika ut, vi har olika hårfärg, är olika långa och har olika hudfärg. Har du någonsin undrat vad det är som gör dig till dig? Svaret är till stor del dina gener. Vi består av celler och varje cell i din kropp har alla dina gener som behövs för att skapa dig. Man kan likna en gen vid ett recept som cellen använder för att veta hur den ska ti
Inom industrin används många typer av värmekällor. Det kan vara öppna lågor, IR strålning, resistiv uppvärmning eller induktionsvärmning. Induktionsvärmningen är en värmingstyp med hög energidensitet, låg investeringskostnad, snabb uppstartstid och hög flexibilitet. Ett serieresonant induktionsvärmningssystem består i sin enklaste form av en växelspänningskälla, en spole, en kondensator och objekt
New products on the market are likely to be simulated in a computer sometime during the development process. The environment for which the physical model of the product is developed may not always be the optimal for control simulations of the model. To be able to export models from one environment to another a common model definition must be defined. The Functional Mock-up Interface, FMI, provides
The aim with this Master’s Thesis work was to conduct research about different available authenticators, as well as implementing a multi-factor authenticator into the currently used login-application. The research included biometric authentication technologies, and investigation of how to implement these to create a highly secure and customizable multi-factor authentication for My Axis-accounts fo
Background: The recently established international cystatin C calibrator makes it possible to develop non-laboratory specific glomerular filtration rate (GFR) estimating (eGFR) equations. This study compares the performance of the arithmetic mean of the revised Lund-Malmo creatinine and CAPA cystatin C equations (MEAN(LM-REV+CAPA)), the arithmetic mean of the Chronic Kidney Disease Epidemiology Co
Hyperresponsiveness and inflammation are major pathophysiological features of both allergic rhinitis and asthma. The mechanisms behind these are not fully understood. The aims of this thesis were to investigate if cytokines involved in the allergic response can induce airway hyperreactivity by affecting the airway smooth muscle directly and to identify novel mediators involved in allergic airway i
In the work described in the present thesis, laser techniques for combustion engine diagnostics were developed and applied. The main techniques were laser-induced incandescence (LII) and laser-induced fluorescence (LIF), used for both flame and engine diagnostics. A novel technique was developed, one in which the relative fuel distribution, as measured by planar laser-induced fluorescence (PLIF),
Popular Abstract in Swedish Rätt förhållande mellan mängden bränsle och luft är viktigt i dagens förbränningsmotorer för att den katalytiska avgasreningen skall fungera. Motorer i serieproduktion mäter syrehalten i avgaserna för att få en uppfattning om blandningsförhållandet. Denna utvecklar en metod att skatta blandningsförhållandet genom mätning av cylindertrycket. Man kan på så sätt få snabbarThis thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. The net heat release profile is computed from the cylinder pressure trace and quantifies the
Objectives To reanalyze randomized controlled trials on the use of umbilical artery Doppler velocimetry in high-risk pregnancies and determine which high-risk pregnancies benefit from the use of Doppler velocimetry, Methods Searching Medline, the Cochrane Library and Embase we found 13 randomized controlled trials on the use of Doppler velocimetry in high-risk pregnancies. Of these, six included p
Popular Abstract in Swedish 1: Tomas Åkerud, doktorand vid Lunds Universitet, har utvecklat en metod för att mäta hur snabbt läkemedelsmolekyler och fettsyror (de naturliga bindarna) tar sig in i och lämnar bindingsfickan i ett protein som är viktigt för fettsyrametabolismen i människa. Proteinet, adipocyt-fettsyrabindande protein (A-FABP), har som funktion att transportera fettsyror, som inte är Nuclear magnetic resonance spectroscopy (NMR) has been used to determine the kinetics of ligand binding to the adipocyte fatty acid-binding protein (A-FABP), as well as the oligomerisation and inter- and intramolecular dynamics of the low molecular weight-protein tyrosine phosphatase (LMW-PTP) in solution. NMR spectroscopy is sensitive to dynamic processes on timescales ranging from picoseconds t
Background. Giant cell tumor of bone (GCTB) is an aggressive primary osteolytic tumor. GCTB often involves the epiphysis, usually causing substantial pain and functional disability. Denosumab, a fully human monoclonal antibody against receptor activator of nuclear factor. kappa beta ligand (RANKL), is an effective treatment option for patients with advanced GCTB. This analysis of data from an ongo
In this chapter, the author analyses a new Swedish curriculum for schools that was presented in 2011 and came into effect the same year. Basically the focus in the subject of music is on playing music, creating music, and listening to music. But key citations within the subject of music show a return to some ideas from the beginning of the 20th century regarding nationalism, a Nordic ethnocentric
Background Compared with placebo, prophylactic treatment with bisphosphonates reduces risk of skeletal events in patients with multiple myeloma. However, because of toxicity associated with long-term bisphosphonate treatment, establishing the lowest effective dose is important. This study compared the effect of two doses of pamidronate on health-related quality of life and skeletal morbidity in pa
Popular Abstract in Swedish Avhandlingen handlar om tes av periodicitet och trend inom långminne-processer. Med hjälp av diskret wavelet transform och periodogram presenteras vi två test för periodicitet och tre test för trend. Vi utvärderar vår test samt studerar deras egenskaper delvis genom att använda oss av datorintensiva metoder såsom Monte Carlo och delvis genom att jämföra dem med andra liThis thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. The first approach we consider to analyse such processes is by using the band periodogram, which divides the periodogram into different intervals or bands, matchi
