SSAB Tunnplåt AB manufactures high strength steel to e.g. beams to trailers, containers, trucks and cars. In high strength steel designs the ratio width to thickness is also high and therefore the risk for local buckling is high. When buckling occurs the stress will re-distribute and large deformation will occur. It is therefore important to take buckling into consideration when dimensioning high
The primary objective of this study is to compare the accuracy of two risk models, International Heart Transplantation Survival Algorithm (IHTSA), developed using deep learning technique, and Index for Mortality Prediction After Cardiac Transplantation (IMPACT), to predict survival after heart transplantation. Data from adult heart transplanted patients between January 1997 to December 2011 were c
Master project made at Lund Institute of Technology Department of Design Sciences, division of Industrial Design in cooperation with Basecamp Explorer. Basecamp Explorer wanted me to be involved in the development of the interior of the guest tents in their camp in Masai Mara, Kenya and the Pyrenees, France. Basecamp Explorer runs ecological tourism destinations on a handful of places in the world
Estimation of radiation damage to electronics is complex and requires knowledge of several disciplines. Such estimation is important in the assessment of design and construction of systems in radiatory applications. This can be used to approximate the lifetime of electronics and to develop strategies for both ensuring reliability of the equipment and for financial optimization. To understand the i
Title: Returns on Assets and Returns on Stocks: Based on Swedish Market. Authors:Tatiana Studyanikova and Eirini Sarantopoulou. Advisor:Hossein Asgharian. Key Words: Returns on assets (ROA), returns on stocks (ROS), variation, principal component analysis, firm-specific level. Purpose: Examine whether common factors of returns on stocks and returns on assets explain most of the variation in return
Popular Abstract in English Cancer diagnostics is an increasingly important task in the modern world due to an increasing cancer incidence and because diagnostics and treatment are given higher priority. There are many requirements to a diagnostic system. First of all it is important to provide an accurate diagnosis to be able to choose the right treatment. In addition, it is preferable that the mOptical coherence tomography (OCT) is a non-invasive optical imaging technique providing approximately 10 micrometer resolution of tissue in vivo. Within ophthalmology, OCT has already proven its value and is routinely used for diagnosing retinal diseases. In many other areas the potential of OCT is explored worldwide, while the technique itself is further developed with improved imaging speed, re
This master’s thesis project report deals with the design of multiplier for the reference signal to the Phase Locked Loop (PLL) used in WLAN application. The reference multiplier designed is based on a newly proposed architecture of dual loop feedback Delay Locked Loop (DLL) in which multiplication is performed within the loops. To lock the DLL, input signal is required to be delayed only for threKamal Kumar Gupta DLL Based Reference Multiplier for the use in a PLL for WLAN applications In modern wireless communication system, a frequency synthesizer/multiplier is one of the main building blocks of the system. For on-chip application, a frequency synthesizer is used as local oscillator (LO) to generate precise frequency from a single base frequency source, usually a crystal oscillator. Th
This bachelor thesis contains an introduction into supersymmetric quantum mechanics(SUSYQM). SUSYQM provides a different way of solving quantum mechanical problems. The thesis explains the basic concepts of SUSYQM, such as the factorization of a Hamiltonian, the definition of its superpotential and the shape invariant potentials. The SUSYQM framework was applied to some problems such as the infini
Children in an asylum process are especially exposed in society. Therefore, a high standard is expected of the law enforcer’s investigation and assessment of the best interest of the child, within the rules for residence permit in the Aliens Act (2005:716). The regulation of the best interest of the child in the Aliens Act (2005:716) protect the child’s right to health and development which to a
