This master thesis describes nonlinear nite element analysis and ex- perimental verication tests of a corrugated board panel when loaded in-plane. Detailed modelling of a panel, where both the liner and fluting is represented in detail, is compared to simplied shell modelling with a solid core and to experimental tests. In the experimental tests, Stereo- scopic Digital Speckle Photography is used t

A low creep rate and a long lifetime are important mechanical properties for corrugated board and its constituent’s linerboard and fluting. These properties ensure that the package protects the goods during the entire duration of transport and storage. This study involves several creep and tensile tests of linerboard in the machine direction (MD). The objective is to investigate how free or rest

This master dissertation describes the process of implementing a coupling between the boundary element method (BEM) and the finite element method (FEM) for three dimensional time harmonic structure-acoustic models in CALFEM, which is a finite element toolbox to MATLAB. Since no boundary elements earlier have been represented in CALFEM the development and implementation of constant and linear boundar

In this master thesis a two-dimensional finite element model describing nonlinear moisture dynamics in paper materials is developed. The aim of the model is to simulate moisture movement in corrugated board boxes due to fluctuating relative humidity. To evaluate the accuracy of the model a simulation is carried out which is being compared to measurements. For the paper material used in the simulati

The course Software Development for Technical Systems at the division of Structural Mechanics teaches students techniques for implementing finite element applications with both user interface and computational code. Currently Borland Delphi environment is used for the user interface and Fortran is used for the computational part. This master’s thesis is an effort to study methods of integrating Fort

Smarttelefonen används alltmer som redskap i psykoterapeutisk behandling men hittills har ingen kontrollerad studie provat om behandling av social fobi kan förmedlas genom smarttelefon. Denna randomiserade och kontrollerade studie undersökte guidad självhjälpsbehandling vid social fobi förmedlad via smarttelefon med syfte att dels jämföra behandlingar och dels att studera olika patientfaktorers beThe use of smartphones as a tool for administering psychological treatment is increasing, however, there is so far no controlled studies showing that social anxiety disorder (SAD) can be treated in this way. This randomized and controlled study, examines Internet based treatment administered through smartphones for social anxiety disorder. Two different types of treatment are compared, and the imp

Spain has in recent years suffered a deep recession with very low growth rates and a growing public debt. The country has in 2012 taken several fiscal measures in order to help overcome its crisis and reduce the public debt. The objective of this study is to analyze some of these changes; tax rises and spending cuts and the increased taxes I have chosen to analyze are the income tax, capital gains

Jag har intervjuat tre sångpedagoger för att förstå hur de balanserar sångteknik, personligt uttryck och röstideal i sångundervisningen. De forskningsfrågor jag sökt svar på är: Finns det ett eller flera röstideal som eftersträvas i sångundervisningen i allmänhet?; Vilket/ vilka är i så fall dessa röstideal?; Påverkar detta ”röstideal” det personliga uttrycket hos eleven och i så fall på vilket säThe vocal coache's task - A study of the balance between vocal technique, self expression and voice ideals. In my research I have been interviewing three vocal coaches to get an understanding of their way of balancing vocal techniques, self expression and voice ideals in their singing lessons. These are the research questions I sought answers to: Is there one or more voice ideals that is pursu

Using spectra of RR Lyrae stars in the Small Magellanic Cloud (SMC) a metallicity snapshot from an early epoch in the history of the SMC could possibly be obtained. The SMC, one of our closest neighbours in the Local Group of galaxies, offers the opportunity to study another galaxy close-up. The history of the SMC can be traced using the chemical characteristics of its different generations of sta

Uppsatsen undersöker med Foucaults diskursteori och Bourdieus teori om fält den debatt och de uppfattningar som omger två organisationsförändringar på Karlshamns lasarett, som är en del av Blekingesjukhuset. Sjukhuspersonal samt landstingspolitiker har studerats som centrala aktörer i frågan. Syftet är att med hjälp av nämnda teorier blottlägga och förstå den pågående maktkampen kring förändringar

Den 16e januari 2012 gick årets Jerringpris vid idrottsgalan till ryttaren, Rolf Göran Bengtsson. Jerringpriset är priset framröstat av folket för årets idrottsprestation och vinsten blev ett startskott för en enorm debatt i media i Sverige. Sporten ifrågasattes och lika så prestationen hos ryttare. Debatten väckte enorma känslor bland sportfantaster, journalister och rid folk, vilket tydligt fram

Aim: The aim of this research was to explore and evaluate the new expected identities of unmarried urban women in China, by analyzing the changes of marriage law in recent sixty years, particularly in property division in the case of divorce. Methodology: The paper proceeded under the qualitative method and designed a case study in Chengdu. The data from books, journals, policies, newspapers and

Popular summary The fate of non-steroidal anti-inflammatory drugs The knowledge about distribution of drugs between sewage sludge, water phases and water living organisms is vital for predictions of the fate and transport routes of toxic substances to the environment. And the distribution of drugs in the environment can be used as a base for risk assessments and it also can be used to define desir

Den här studien ägnas åt att närmare fördjupa sig i hur kontaktpersoner enligt LSS upplever och ser på betydelsen av en matchningsprocess mellan brukare inom LSS och blivande kontaktpersoner. Rekrytering av kontaktpersoner sker på uppdrag av kommunerna i vårt land. Matchningsprocessen kan skilja sig åt från kommun till kommun och uppdraget att utföra insatsen kan utföras av socialsekreterare inom

Johan Ekeblad was a Swedish diplomat and nobleman during the period of the Swedish Empire in the 17th century who is mostly known for his letters, written in an impressionistic and highly modern style. This paper aims to treat Johan Ekeblad and his writing as a representative of a new form of mentality that emerged amongst Swedes when Sweden due to its new power reemerged on the European scene. Th
