Upprinnelsen till detta examensarbete var att Otis Stockholm, som också leder den svenska verksamheten, saknade en processkarta för nymontageavdelning. Försök hade gjorts tidigare med att göra en processkartläggning, men man hade då inte kommit hela vägen. Man ville nu från ledningens håll ha en karta på processen så att alla gjorde på samma sätt från projekt till projekt. Processen var uppdelad iThe impetus for this thesis was the identification of the need for a process map for processing new equipment within Otis Sweden. The company had tried before to map their process but had not fully developed the model. This time managers wanted a process map to stabilize the process of managing employees to ensure consistency across projects. The process has been spit in two functions, the sales a

The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. The moisture in the paper is controlled by adjusting the set point of the steam pressure controllers. There exist several commer

The aim of this study is to investigate how Lunds Vokalensemble achieves its goals and in which way the goals influence the choir's work. The study also explores the choir's artistic process. Qualitative interviews and observations were used as a method. Four singers and the director participated to the interviews. The results show that the choir's artistic goals have quite an influenc

Partially due to years of poor water management practices in Moldova, water resources are increasingly becoming a concern. This situation is intensified by the pollution of water bodies that could be used for drinking water supply. An improvement of the water supply system in Moldova’s capital city Chisinau would result in an upgrading of water quality and hence increased health and living conditi

In the newly founded state Kosovo, the women’s rights movement has become a strong voice on gender equality and contributes in important ways to strengthening women’s rights. At the same time, highly gendered political structures restrict the movement’s access to political influence. The purpose of this thesis is to explore how the political opportunities and challenges that the movement faces hav

This study examined how outer and expanding circle cultures were depicted in two English as a foreign language (EFL) textbooks aimed at English 5 in Swedish upper secondary school. Moreover, it was investigated to what extent these depictions aligned with the steering documents by helping students fulfil the aims related to intercultural competence (ICC). In order to develop ICC, students must see

We estimated the CH4 budget in Finland for 2004–2014 using the CTE-CH4 data assimilation system with an extended atmospheric CH4 observation network of seven sites from Finland to surrounding regions (Hyytiälä, Kjølnes, Kumpula, Pallas, Puijo, Sodankylä, and Utö). The estimated average annual total emission for Finland is 0.6 ± 0.5 Tg CH4 yr−1. Sensitivity experiments show that the posterior biosp

Although the existence of a large carbon sink in terrestrial ecosystems is well-established, the drivers of this sink remain uncertain. It has been suggested that perturbations to forest demography caused by past land-use change, management, and natural disturbances may be causing a large component of current carbon uptake. Here we use a global compilation of forest ag

The Global Gridded Crop Model Intercomparison (GGCMI) phase 1 dataset of the Agricultural Model Intercomparison and Improvement Project (AgMIP) provides an unprecedentedly large dataset of crop model simulations covering the global ice-free land surface. The dataset consists of annual data fields at a spatial resolution of 0.5 arc-degree longitude and latitude. Fourteen crop modeling groups provid

Biological nitrogen fixation (BNF) from grain legumes is of significant importance in global agricultural ecosystems. Crops with BNF capability are expected to support the need to increase food production while reducing nitrogen (N) fertilizer input for agricultural sustainability, but quantification of N fixing rates and BNF crop yields remains inadequate on a global scale. Here we incorporate tw

Background: There is limited research on prevention of mental ill-health of school personnel and the systematic management of school work environments. The aim of this study was to assess the effectiveness of implementing the guideline recommendations for the prevention of mental ill-health in schools, in particular, whether there was a difference in adherence to guideline recommendations between

Enhanced warming in the Arctic (Arctic amplification, AA) in the last decades has been linked to several factors including sea ice and the Atlantic Multidecadal Oscillation (AMO). However, how these factors contributed to AA variations in a long-term perspective remains unclear. By reconstructing a millennial AA index combining climate model simulations with recently available proxy data, this wor

The magnitude and distribution of China's terrestrial carbon sink remain uncertain due to insufficient constraints at large scales, whereby satellite data offer great potential for reducing the uncertainty. Here, we present two carbon sink estimates for China constrained either by satellite CO2 column concentrations (XCO2) within the Global Carbon Assimilation System or by remotely sensed soil moi

C4b-binding protein is involved in the regulation of the complement system. It is a multimeric protein composed of seven identical alpha-chains and a single copy of a unique beta-chain. The latter was identified only recently and its structure determined by cDNA cloning. Both subunits in C4b-binding protein belong to the same superfamily of proteins composed predominantly of tandemly arranged shor

Peatlands are important carbon reserves in terrestrial ecosystems. The microtopography of a peatland area has a strong influence on its carbon balance, determining carbon fluxes at a range of spatial scales. These patterned surfaces are very sensitive to changing climatic conditions. There are open research questions concerning the stability, behaviour and transformation of these microstructures,

Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land-based climate change mitigation efforts is highly uncertain. Here, we address this uncertainty by using two land-based mitigation scenarios from two land-use models (IMAGE and MAgPIE) as input to four dynamic globa

Uncertainty in our calculations of a system reveals the limits of our knowledge. This limitation makes model representations of the Earth system challenging and our predictions less reliable. However, despite appearing chaotic and non-linear, a system always follows a deterministic trajectory, which can often be expressed probabilistically. Building on this concept, this thesis applies data assimi
