The reduction of the surface oxide on Rh(111) by H-2 was observed in situ by scanning tunneling microscopy (STM) and high-resolution core level spectroscopy (HRCLS). At room temperature, H-2 does not adsorb on the oxide, only in reduced areas. Reduction starts in very few sites, almost exclusively in stepped areas. One can also initiate the reduction process by deliberately creating defects with t
The present work aims to study preparation of thin MIP films on a gold-coated QCM resonator in a well-controlled and reproducible manner. A surface-bound photo-radical initiator was used to furnish an imprinting polymerization in a dilute solution of template, functional monomer and crosslinker. Prior to polymerization, the photo-initiator was covalently coupled to a self-assembled monolayer of ca
This paper presents results of an all-sky search for periodic gravitational waves in the frequency range [50, 1190] Hz and with frequency derivative range of similar to[-20, 1.1] x 10(-10) Hz s(-1) for the fifth LIGO science run (S5). The search uses a noncoherent Hough-transform method to combine the information from coherent searches on time scales of about one day. Because these searches are ve
This is a collection of projects that were written by students participating in our course on Gender in Science and Technology at Lund University. The course is based on a collaboration between the Department of Physics, the Science Faculty and the Department for Gender Studies, the Social Science Faculty. It is something of a record breaker in longevity, since in the autumn of 2014 it will run fo
Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical problem. In the literature there are man
This thesis describes analysis of data from the DELPHI Very Small Angle Tagger (VSAT) calorimeter at LEP1. The VSAT consists of four Silicon-Tungsten calorimeter modules symmetrically positioned 7.7 meters away from the interaction point. It measures elastically scattered electrons and positrons, Bhabha events, within the polar angular region between 5-12 mrad. Trigger efficiency and reconstructio
We apply first- and second-order splitting schemes to the differential Riccati equation. Such equations are very important in e.g. linear quadratic regulator (LQR) problems, where they provide a link between the state of the system and the optimal input. The methods can also be extended to generalized Riccati equations, e.g. arising from LQR problems given in implicit form. In contrast to previous
The purpose of the present study was threefold: (a) to replicate the finding by MacLeod and Rutherford (1992) that low trait-anxious individuals, in contrast to high trait-anxious individuals, show a selective attention away from subliminally presented threat words at elevated levels of stress; (b) to test the hypothesis that this effect is due to individuals with repressive coping-style rather th
A very simple and extremely computationally efficient algorithm for blind separation of two speech sources from two mixtures is presented in this paper. The algorithm exploits the approximate W-disjoint orthogonality of speech signals and assumes specific sensors (microphones) setting that allows the sources to possess a feature we call cross high-low diversity. Two sources are said to be cross hi
A novel method is presented and explored within the framework of Potts neural networks for solving optimization problems with a non-trivial topology, with the airline crew scheduling problem as a target application. The key ingredient to handle the topological complications is a propagator defined in terms of Potts neurons. The approach is tested on artificial problems generated with two real-worl
Progressive supranuclear palsy and Parkinson's disease have distinct underlying neuropathology, but both diseases affect cognitive function in addition to causing a movement disorder. They impair response inhibition and may lead to impulsivity, which can occur even in the presence of profound akinesia and rigidity. The current study examined the mechanisms of cognitive impairments underlying disin
The aim of this thesis was to elucidate developments in epidemiology, clinical manifestations and complications in Chlamydia trachomatis (C.trachomatis) and Mycoplasma genitalium (M.genitalium) infection. In study I the frequencies of non-gonococcal salpingitis, gonococcal salpingitis and ectopic pregnancy (EP) were observed over a period of 28 years and correlated to the prevalence of Neisseria g
The aim of this study was to investigate if it is possible to dry concrete samples in a microwave aven without damaging the concrete. This method could, if it is possible, fadilitate the work in many laboratories today. In the beginning of the work a theoretical study over the behavior of the microwaves is done. Same different areas in the construction business where it is possible to use microwav
Följande rapport behandlar Kårhuset vid Lunds Tekniska Högskola. Byggnaden består av fem plan och är byggd i mitten av 90-talet. Kårhuset innehar verksamheter av varierande karaktär, exempelvis föreläsningssalar, restaurang, kontor och bastu, vilket resulterar i att byggnaden har en hög besöksromsättning. Målet med rapporten är att framställa en brandteknisk riskanalys avseende personsäkerheten,The following report is an evaluation of the fire safety of Kårhuset, Faculty of Engineering at Lund University. The aim of the evaluation is to review the personal safety, which means investigating whether the available time for evacuation out of the building is enough, in case of fire. Further on, the evaluation relies on a qualitative risk analysis, where three worst credible cases were discove
Risk is of large importance for financial institutions and there are many different measures that can be used. A popular one is value at risk (VaR), which is the maximum likely loss for a portfolio of financial assets. Different methods of estimating it has been suggested, one often described is the variance-covariance method. Here a method based on a generative model called generative adversarial
Rendering and simulating an ocean as realistic as possible is a desirable effect to many outdoor scenes of movies and video games. The difficulties with simulating a plausible ocean arise from the complex behavior and scaling of the ocean waves. The length of the waves may vary from being just a few millimeters up to several kilo meters long and the waves can for instance break and line up with th
Natural light brings a sense of presence to the physical environment. The interaction between natural light and form puts us in connection with place in a way that can not be simulated or replaced with artificial light. This relationship has fascinated and engaged architects of all times, you could claim that the question of light and form lies at the core of architecture. It is hard to work with
In myoelectric prosthesis design, there is often a trade-off between control robustness and range of executable movements. As a low movement error rate is necessary in any real application, this often results in a quite severe limitation on the dexterity of the user. One possible remedy for this could come from the use of multi-label machine learning methods, where complex hand movements can be ex
