We developed an analytical theory for the many-body potential of mean force (POMF) between N spheres immersed in a continuum chain fluid. The theory is almost exact for a T polymer solution in the protein limit (small particles, long polymers), where N-body effects are important. Polydispersity in polymer length according to a SchulzFlory distribution emerges naturally from our analysis, as does t
Grating interferometer based imaging with X-rays and neutrons has proven to hold huge potential for applications in key research fields conveying biology and medicine as well as engineering and magnetism, respectively. The thereby amenable dark-field imaging modality implied the promise to access structural information beyond reach of direct spatial resolution. However, only here a yet missing app
Selecting the appropriate analytical methods for characterizing the assembly and morphology of polymer-based vesicles, or polymersomes are required to reach their full potential in biotechnology. This work presents and compares 17 different techniques for their ability to adequately report size, lamellarity, elastic properties, bilayer surface charge, thickness and polarity of polybutadiene-polyet
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
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
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
We present a numerical scheme for the solution of the initial-value problem for the “bad” Boussinesq equation. The accuracy of the scheme is tested by comparison with exact soliton solutions as well as with recently obtained asymptotic formulas for the solution.
Induction heating is used in many industrial applications to heat electrically conductive materials. The coupled electromagnetic-thermal induction heating process is non-linear in general, and for ferromagnetic materials it becomes challenging since both the electromagnetic and the thermal responses are non-linear. As a result of the existing non-linearities, simulating the induction heating proce
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
In this paper, we present a global solution to a nonlinear H-infinity optimal control problem for control-affine systems with an associated potential function. We also give a closed-form expression for an optimal controller and demonstrate its potential for sparsity. This paper thus advances a recent result which considers the same problem restricted to systems with symmetric state matrix and nonl
With the increasing portfolio of options when looking for new mobile apps and web tools their is a need to excel. One of the possible solutions is to capture and hold on to the users by introducing gamification that motivates the user and gives them the opportunity to feel more engaged with a product. This master thesis examines a possible gamification design for the software solution KLAR. KLAR c
Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c
