Assume that we have two perspective images with known intrinsic parameters except for an unknown common focal length. It is a minimally constrained problem to find the relative orientation between the two images given six corresponding points. To this problem which to the best of our knowledge was unsolved we present an efficient solver. Through numerical experiments we demonstrate that the algori
Den här rapporten redovisar det arbete som utförts av Andreas Byström och Josefin Salomonsson inom ramen för civilingenjörsprogrammets examensarbete. Arbetet har utförts på Scania, avdelningen för specialfordon från november 2009 till april 2010. Scania har en lång bakgrund som leverantör av militära fordon till försvarsmakter världen över. Scanias militära lastbilar är uppbyggda av samma grundstThis report is a result of a Master Thesis project in mechanical engineering by Andreas Byström and Josefin Salomonsson. The thesis was carried out at Scania CV AB at the department for Special Vehicles and the Division of Machine Design at the Department of Design Science at LTH from November 2009 to April 2010. Scania has a long tradition of designing and deliver vehicles to national defence fo
This report is part of a Master Thesis Project in Mechanical Engineering with Industrial Design at the Faculty of Engineering LTH at Lund University. The project was performed in collaboration with Hammarplast Consumer Ab, a Swedish company founded in 1947 manufacturing household items in plastic. Hammarplast Consumer Ab is part of the Orthex group, which is the leading Nordic company within t
Biochar is a recalcitrant carbon rich solid product widely praised for the ability to improve soil fertility and sequester carbon, thereby improving crop yields and mitigating climate change. In addition to this, gaseous by products from production can be combusted for energy. Despite the recent global peaks in biochar research, studies focused on temperate regions are relatively scarce and few Eu
There is a lot of discussion going on how to adapt to the changing climatic conditions, especially in countries where financial resources are limited. The built environment has been identified as a key area of intervention. As disasters, such as typhoons, can devastate entire cities, it is essential that the most important buildings in these cities, the lifelines so to speak, are resilient and can
Assume that we have two perspective images with known intrinsic parameters except for an unknown common focal length. It is a minimally constrained problem to find the relative orientation between the two images given six corresponding points. We present an efficient solution to the problem and show that there are 15 solutions in general (including complex solutions). To the best of our knowledge
Modern wind turbines are designed to withstand approximately for a lifetime of 20 years [1]. However, a very long design life of 100 years or more can be expected for high-quality concrete foundations. Thus there is a big difference in lifetime between wind turbines and foundations. There is a significant economic benefit of replacing the out-of-date wind turbine with a new turbine of better power
Growing US-Israeli tension over continued East Jerusalem settlement construction – which the White House appears unable to stop – underscores a deeper reality: The two-state solution is no longer possible. What are the alternatives? For the past few years, the idea of a “parallel states” structure has been discussed, suggesting a scenario with a two-states structure on the same land, both states c
In this chapter we summarize the solution developed by team KTH for the Amazon Picking Challenge 2016 in Leipzig, Germany. The competition, which simulated a warehouse automation scenario, was divided into two parts: a picking task, where the robot picks items from a shelf and places them into a tote, and a stowing task, where the robot picks items from a tote and places them in a shelf. We descri
Limited-slip differentials (LSD) are normally placed in high-end and race cars to improve the handling, by reducing the differential speed and balancing the torque between the driving wheels. However, electrical-activated LSD struggles to continuously eliminate the differential speed over extended periods of time. To overcome this, BorgWarner proposed a dual-functional clutch pack, featuring two d
Platelets express Toll-like receptor 4 (TLR4), and this has been shown to be responsible for the thrombocytopenia induced by lipopolysaccharide (LPS) administration in vivo. We studied the role of LPS in mediating platelet phagocytosis by THP-1 cells in vitro by flow cytometry. Opsonization of platelets with an IgG monoclonal (W6/32) antibody or with IgG autoantibody-positive sera from patients wi
As young people increasingly relocate due to work, study and shifting life circumstances, they are constantly adapting to new living environments and spatial layouts. This project explores how lighting design can support this evolving “nomadic” lifestyle — helping individuals establish a sense of home more quickly within unfamiliar spaces. It further investigates how lighting and furniture can bec
Background We present 2DDB, a bioinformatics solution for storage, integration and analysis of quantitative proteomics data. As the data complexity and the rate with which it is produced increases in the proteomics field, the need for flexible analysis software increases. Results 2DDB is based on a core data model describing fundamentals such as experiment description and identified proteins. The
Fiber-reinforced polymers are highly demanding composites in aerospace and automotive areas because of their excellent mechanical properties such as stiffness and strength-to-weight ratio. The drilling remains the major machining operation applied to composites to provide high-quality holes for joints between parts. Due to composites plied structure, the drilling is accompanied with unusual form m
Digital Subscriber Lines (DSL) are today one of the most important means for delivering high-speed data transmission. Dynamic Spectrum Management (DSM) is an emerging technique for dealing with crosstalk, one of the technology's most harmful problems. DSM judiciously designs users' power spectral densities so that the overall system performance is improved. This works aims at presenting a new insi

The central inquiry in the current paper is a critical design-for-all challenge: how might universal design contribute to providing equitable healthcare for women suffering from pelvic floor injuries during birth?
