Failures due to instability phenomena will happen suddenly and can cause the whole structure to collapse. It’s therefore in the engineer’s best interest to have a good knowledge about these phenomena. One example of instability phenomena is column buckling, which is the main focus of this thesis. The main cases that are being evaluated have a single brace in the middle of a timber column with hi
Knapp-Moving is interersted in changing their testloop. They are currently using an old PLC and want to change to a more modern PLC. The PLC that the company is currently using is a Siemens s7-300 and it's our job to change the system to a Siemens s7-1200. When we have rebuilt and implemented the new system we are going to investigate if their new bought motors are more efficient than the old
This Master´s Thesis has been carried out at the Division of Machine Design, Department of Design Science, LTH and is about studying the signification and importance of “proof of concept” and its place in the product development process. The first part of this assignment consisted of examining existing product development methodologies and to find out to what extent the proof of concept activity i
Nitrous oxide (N2O) is one of the three primary anthropogenic greenhouse gases. The agricultural sector accounts for 75.7 % of all anthropogenic N2O emissions in Germany (Umweltbundesamt, 2012). Thus, accurately estimating N2O emissions as well as mitigation strategies for N2O are crucial. This study optimizes the process-based model DNDC to simulate N2O emissions by conventional winter wheat and
Urban mobility as we know it is changing. On the one hand, challenges persist ranging from climate change, increasing urbanization and demographic change. On the other hand, recent technological advances enable novel approaches to mobility altogether. This paper investigates Personal Rapid Transit (PRT) as one such innovative mobility form in the context of the changing urban mobility paradigm. Du
The healthcare sector, currently accounting for about seven percent of global GDP expenditure, faces growing demand pressures driven by factors such as ageing populations and growing prevalence of chronic diseases. Consequently, the sector is increasingly looking for innovations that can simultaneously improve the efficiency and quality of care. Healthcare innovations could in turn make large cont
This study aims to answer two research questions with focus in Sida’s International Training Program: Child rights, classroom and school management, the two questions regard the knowledge transfer process. The first one focuses on how the participants of the program express knowledge and knowledge transfer and the second one highlights what contextual factors that affect the processes on three dif

The RADASS (Remote Access Dual Automatic Switch Spray) system is thought to be the future solution for frozen rail switches. Frozen switches are a yearly reoccurring issue and cause long delays in rail traffic, which require a vast amount of personnel and resources to fix. Spraying chemicals manually by railway workers is the most common method to deal with the issue; the system intends to automat
Minskning av barnfattigdom har de senaste decennierna varit ett hett ämne på den politiska dagordningen i rika länder. Trots att Sveriges barnfattigdom är låg, relativt till andra länder, innebär den enorma samhälleliga förluster i form av minskat humankapital. I denna uppsats har barnfattigdomen i Sveriges kommuner undersökts och analyserats för åren 2007 till 2012. Infallsvinkeln är ny och ger e
Multi-atlas segmentation is a widely used method that has proved to work well for the problem of segmenting organs in medical images. But standard methods are time consuming and the amount of data quickly grows to a point making use of these methods intractable. In this work we present a fully automatic method for segmentation of the pericardium in 3D CTA-images. We use a multi-atlas approach base
Arbetet är en examensuppsats på termin sex vid Ekonomiska Högskolan Lund, systemvetenskapligt kandidatprogram. Arbetet skall skänka ett mindre kunskapsbidrag inom Informatik och behandla kritiska framgångsfaktorer för ERP-implementationer. Vi har utgått ifrån en förundersökning på rådande empiri inom ämnet för att avgränsa oss till ett urval nyckelfaktorer, som sedan undersökts med datainsamling i
Chemiluminescent emission from OH*, CH* and C2* radicals and its dependence on the equivalence ratio is being investigated in the current study. The aim of this project is to use the results for combustion control on marine vessels and safety checks. The study was conducted in collaboration with Kockumation, a leading company in developing control systems for running boilers and steam turbines on
Inom den Svenska byggindustrin har Betonghandboken Material länge tjänat som ett naturligt val av hjälpmedel för ingenjörer som har stött på ett betongtekniskt problem. Den senaste utgåvan av Betonghandboken material publicerades 1994. Detta gör att många av de kunskaper vi har idag inom betongområdet går outnyttjade då man använder sig av Betonghandboken. Det finns ett behov att sammanfatta de ku
As part of the development of the European electricity grid, the EU has decided that ‘Smart Meters’ should be installed in 80% of the households of the EU by 2020. It is expected that this will lead to a reduction of energy use in the residential sector in the order of 10%. Driven by the so-called ‘Information-Deficit’ model, a critical assumption in this policy development is that provision of in
This report describes a bachelor thesis project realized as the final exercise in the Computer Science program at Lunds Tekniska Högskola, Campus Helsingborg. The thesis work was done as an Android app-development project at Telavox in Malmö, a company active in the IP-Telephony business. The purpose of the project was to develop an Android application to be used by the sellers at the company. The
Inter-governmental climate talks have, over a twenty-year period, had little success in implementing measures to mitigate human-induced climate change. Their fundamental perspective, one of economic rationality, has not provided a compelling or effective basis for achieving their desired goals. Over the same interval, at the local scale, various constituencies have come together to address climate

This research draws attention to the way undocumented Albanian immigrant women experience their everyday life in Greece. Which are the structural factors experienced by Albanian undocumented immigrant women that defines their everyday life in Greece and what strategies are used by these women in order to resist these macro-structural factors. Qualitative interviews were held with 11 undocumented A
