In the present work we have selected a collection of statistical and mathematical tools useful for the exploration of multivariate data and we present them in a form that is meant to be particularly accessible to a classically trained mathematician. We give self contained and streamlined introductions to principal component analysis, multidimensional scaling and statistical hypothesis testing. Wit
Efter HSVs utvärdering av CI- utbildningarna fick högskolorna ett tydligt uppdrag att vid uppföljningen redovisa hur hållbar utveckling kommer in i utbildningarna. I planeringsförutsättningarna för de 5-åriga civilingenjörsutbildningarna vid LTH finns kravet på examination av minst 6 hp inom området.
The paper describes a novel method for self tuning cylinder pressure based heat release computation that is suitable for online usage in e.g. combustion phasing control applications. The method estimates the polytropic exponents and cylinder pressure offsets immediately preceding and succeeding the combustion event respectively using a fast nonlinear least squares method. The polytropic exponent a
Embedded systems are a characteristic but intangible part of an embedding environment. This poses a severe testing problem that gets further aggravated in embedded networks. The co-presence of hardware and software needs both behavioral and structural aspects to be covered, preferably by a single on-chip paradigm. The paper investigates the potential role of neural networks and introduces a Built-

Denna uppsats kartlägger de centrala faktorerna som påverkar styrelsens storlek i noterade större bolag. Ett flertal variabler har identifierats som centrala för styrelsestorleken. De främsta faktorerna är ökat intresse för styrelsens funktion bland allmänheten, ökad opinion kring mångfald i styrelsen samt förändring av styrelsens funktion
Inom späd- och småbarnspsykiatrin behandlas familjer av en mängd olika anledningar. Det kan bero på dåligt mående hos föräldern, att känslorna för barnet inte är så starka som förväntat, att relationen mellan barn och förälder är konfliktfylld eller att det finns en oro över barnets symtom. Föreliggande studie syftade till att undersöka och beskriva den kliniska populationen inom två späd- och småIn child and infant mental health clinics families are treated for a variety of reasons. It may be that the feelings expressed for the child by the parent may not be as expected, due to the mental health problems of the parent, or that the relationship between the child and parent is filled with conflict, or that there is a parental concern for the child's symptoms. This study aimed at investi
There is an urgent need to ensure sustainable consumption patterns in western countries such as Sweden. Movements around the world demanding leaders to take action for the survival of our planet also puts pressure on companies to act responsibly. Since consumption patterns are influenced by the decisions made by companies on how to do business the choice of business model can promote or hinder mor
The conference series European Conference on Scientific Publishing in Biomedicine and Medicine (ECSP) was originated at the Faculty of Medicine, Lund University, Sweden and was for the first time launched in Lund in 2006. The mission to be highly relevant for researchers was retained at the second meeting, hosted by University of Oslo, Library of Medicine and Health Sciences. The meeting focused o
This thesis investigates the topic of joint positioning and radio channel estimation and prediction. Both positioning and radio channel estimation have a long history of research with many publications but the combination of the two has so far at large been left unexplored. The reason for studying this topic is twofold: improvement of positioning and improvement of radio channel prediction. Positi
Under de senaste åren har det skett en ökning av antalet unga kvinnor som använder sig av vitt nikotinsnus i Sverige. Det har gjorts uttalanden kring att detta är ett problem för folkhälsan då unga riskerar att bli beroende av en skadlig produkt. En del av problemet samt de diskussioner som uppdagats kring ämnet har varit bristen på marknadsförings- och försäljningsregler, vilket har gett företag Over recent years, there has been an increase in young women’s use of white nicotine pouches in Sweden. Statements have been made about this being a problem for public health since young people risk addiction to a harmful product. Part of the problem and discussion has been the lack of marketing and sales regulations, which has given companies the full ability to target specific groups. Considerin
