This master thesis is on Statistical Process Control (SPC). The objective is to evaluate if SPC can be used in a process that produces plates for heat exchanger, the process evaluated is located at Alfa Laval Lund AB. The products are produced in the process by punching and shearing metal coils. An ambition in the project is also to increase the knowledge about Statistical Process Control at Alfa

Cardiovascular diseases are accountable for almost 50 % of the mortality number in Europe which is why research on its causes is highly prioritised. For practical and ethical reasons, in vitro study models are of high importance to enable research on cardiac abnormal behaviours. To meet this issue, researchers from Imec, Belgium, developed Neuray-II, the second generation of a biocompatible chip w

This report is the result of a masters project conducted at the Division of Structural Mechanics at Lund University. The purpose of the project was to integrate a FEM mesh generator with the Python version of the code library CALFEM and improve the mesh visualisation capabilities of said library. This report describes how the mesher software Gmsh and the visualisation library visvis were integrate

The migration of people by sea is not a new phenomenon. Since early days, people whose lives have been under threat or people in search of better living conditions often have taken this route. However, today States are trying to prevent every attempt of irregular migration as they have established policies of interception at sea. They often engage in interceptions without taking into consideration

China’s economic reform has opened fresh flood into global market and its recent performance in overseas investment attracts world attention. Through a comparison in motivation, location choice and market entry mode with other Asian economies, as well as theoretical explanations from institutional perspective, this study intends to discover their similarities and differences, thus how unique China

This paper attempts to describe how young entrepreneurs in high-tech startups frame strategic decisions. Furthermore it seeks to identify how different types of decisions/situations affect the application of different types of logics. Lastly it aims to explore how and why these frames change over time if they do. The insights should indicate how decision-making in practice relates to existing theo

After the 1980s, neoliberalism became the dominant philosophy of development across the world. Whereas the widespread implementation of neoliberal economic policies contributed immensely for a maximization of world economic integration and activity, critics argue that the ideology was also responsible for dramatically widening the inequality gap between and within nations, as well as for the incre

There are many valuable substances present in nature such as antioxidants. The conventional method for extracting the antioxidants employs organic solvents. Subcritical Water Extraction (SWE) is a sustainable method for extraction of high valuable compounds. This method uses subcritical water as a solvent instead of organic solvents but leaves the compounds in a water solution. Keeping the antioxi

Helsingborg, a coastal city in southern Sweden, has initiated a twenty-five yearlong re-development project called H+, aiming to convert the southern industrial harbor space into a new, livable urban neighborhood and city center. The winning plan for the H+ project, titled ‘The Tolerant City,’ is an inherently social redevelopment that requires innovative and collaborative strategies, as well as a

Models for materials with nonlinear electromagnetic response are examined. Three simple physical causes for nonlinear behavior are presented: electronic polarization, molecular direction and electrostriction. Some introductory results and approximations for nonlinear, dispersive media are given, such as the phase-matching criterion, Miller's rule, the Born approximation and the slowly varying ampl

Popular Abstract in Swedish Kärleksdofter och varningsljud i bekämpning av nattfjärilar Jag har studerat hur populationer av skadegörande nattfjärilar kan bekämpas med miljövänliga metoder där djurens egna sinnessystem manipuleras. Liksom många andra insekter kommunicerar nattfjärilar med artspecifika doftsignaler (feromoner) vid parning. Honan avger doften i enstaka nanogram (miljarddels gram!) The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. segetum under natural and pheromone-based mating disruption conditions was monitored by harmonic radar. Individual males were equi

Popular Abstract in Swedish Papillomvirus infekterar ett brett spektrum av ryggradsdjur, såsom människa, olika ap-arter, ko, älg, elefant, ren och bofink. Dessa virus kan ge så vitt skilda symptom som cancer och vårtor. De indelas efter vilken art de infekterar, och inom arterna efter skillnad i DNA-sekvens mellan olika isolat (typer). Hittills har 92 humana papillomvirus (HPV) typer beskrivits, oPapillomaviruses are a diverse, epitheliotropic group of viruses. Some genotypes are the main cause of anogenital cancer in humans; others can induce skin lesions. In order to investigate the occurrence of subclinical skin infections with human papillomavirus (HPV), a pair of degenerate primers (FAP59/64) was designed. Moist cotton-tipped swabs were used as a gentle method of sample collection. Di

New calorimetric methods for direct measurement of solubility and solvent activity are presented. The classical role of calorimetry for measurements of enthalpic parameters is abandoned and the technique is instead used for assessing thermodynamic quantities related to the chemical potential of a substance in a solution. Isothermal calorimetry is here employed as a general analytical method where

In this paper, robotic sensor fusion of acceleration and force measurement is considered. We discuss the problem of using accelerometers close to the end-effectors of robotic manipulators and how it may improve the force control performance. We introduce a new model-based observer approach to sensor fusion of information from various different sensors. During contact transition, accelerometers and

Dendritic cells (DC) are a heterogeneous lineage of bone-marrow-derived leukocytes that serve as the link between innate and adaptive immunity. They are professional antigen-presenting cells that play an important protective and regulatory role in both health and disease. This thesis is based upon six original papers that deal with the function and transcription of human DCs, with focus on their r

The chapter makes use of the theoretic horizons of radical democrac, especially as found in the works of Chantal Mouufe, to conceptually explore the emergence of citizens' identities as active agents in the context of extra-parliamentarian political engagement using the Internet

Popular culture and tourism are intertwining. The use of film and literature amongst destination marketing organisations is a global trend, but how can we understand this phenomenon and all the processes involved? Up to now popular culture and tourism have been researched mainly from a single media perspective. However, it is difficult to separate the impact of one media product from that of anoth
