This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

The purpose with this disertation is to find if there are selected factors which can force companies to grow. We have chosen five factors which we think can force the companies; market, strategy, profitability, demographic and institutional factors. We want to examine if there are differences between small and larger companies, and if there are differences between the lines of business.The intention to growth is also influenced by different factors. The organization and the board have an effect on the development. There are also factors that can obstruct the growth, for example control.

The 1900s saw two incidents of states using their military in civil disorder situations, which resulted in the killing of unarmed citizens. May 14, 1931 in Ådalen, marks a significant part of Swedish history and its view of the use of military force.  On that day, a peaceful protest march escalated, which resulted in live firing by the military stationed there to uphold law and order. This resulted in the deaths of five civilians and the prohibition of the use of military force in incidents of civil disorder. In 1972 in Northern Ireland a similar event took place on January 30, which is commonly known as Bloody Sunday. The Troubles were raging and resulted in protests for civil rights by nationalists.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..

This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.

Background: In the martial art of Muay Thai, techniques are used with hands, elbows, knees and kicks. The contestants are divided into different weight classes and experience levels. The Swedish martial arts association has decided that techniques with elbow are not allowed in B-class. Why is it so?Objective: The aim of this study was to investigate whether the martial arts delegation decision to restrict techniques with elbows to the head in the B-class is justified.

In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.

Syftet med uppsatsen är att jämföra hur grunderna för ansvarsfrihet från skadestånd vid fullgörelsehinder är uppbyggda i olika normsystem för att utifrån en komparativ analys komma fram till vilket system som är bäst tillämpbart i en situation liknande den i scenariot med den försenade vaccinleveransen som jag beskrivit i inledningen till uppsatsen.De regler jag valt att studera för en komparativ jämförelse är kontrollansvaret i den svenska köplagen 27 § och CISG art. 79, modellagarna PECL och Unidroit Principles regler om force majeure och hardship, standardklausulerna i ICC 2003 Force Majeure and Hardship Clauses samt den engelska läran om frustration. Att jag valt att studera teorin om hardship beror på att teorin är starkt sammankopplad till reglerna om force majeure och kontrollansvar. Jag har valt PECL och UNIDROIT som exempel på hur modellagar kan vara upplagda. Fler modellagar och principer finns.

This thesis provides a comparison of the old Planning and Building act (PBA) from 1987 with the new PBA, which entered into force in May 2011. The essay consists of a descriptive part that presents the regulation of both laws. The new PBA consists of several differences compared to previous regulation. This thesis will, however, primarily be centred around the regulation regarding building permit appeals and the possibility of building permit, to gain legal force.In the old PBL, there were no regulations that result in a building permit decision could be made effective. Instead, a building permit could, long after the decision had been made, be over-challenged.

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.
