Representing 3D shape deformations by high-dimensional linear models has many applications in computer vision and medical imaging. Commonly, using Principal Components Analysis a low-dimensional subspace of the high-dimensional shape space is determined. However, the resulting factors (the most dominant eigenvectors of the covariance matrix) have global support, i.e. changing the coefficient of a

Humanitära interventioner, alltså militära ingripanden i en stat utan dess samtycke för att skydda befolkningens mänskliga rättigheter, har under de senaste årtiondena varit omdiskuterade. Interventionernas förespråkare menar att vi alla har en moralisk skyldighet att hjälpa människor i nöd. De som är kritiska till interventionerna menar att dessa innebär en kränkning av en av folkrättens hörnstenHumanitarian interventions, that is to say military interventions in a state, without its permission, to protect the population’s human rights, have during the past decades been controversial. The advocates of the interventions regard it as everyone’s duty to help humans in need. The interventions’ critics argue that the interventions are a violation of one cornerstone of the international law, th

The Swedish transport administration (Trafikverket) uses turnkey contracts as a tool in their work with the assignment from the Swedish government to increase innovation and productivity in the construction sector which railway is included in. Qualitative interviews of the three different actors: clients (Trafikverket), constructors and consults have been made for the study. This is to get a pictu

The problem of finding appropriate probabilities for crossover and mutation with respect to resampling may be addressed using the Markov chain model. Our efforts in this direction lead through a simplification of the mixing matrix incorporating both probabilities. We present the simplification and discuss some of its ramifications. We expect that it may lead to some improvement of the computationa

Feedback in server systems has during last years gained much interest in order to fulfill still increasing demands on performance and optimization regarding, for example, quality of service (QoS) requirements. In this paper we investigate a feedback–based prediction scheme for controlling a single server queue. This control structure has the benefit over other previously suggested control structur

This paper presents a low complexity, yet power efficient technique to boost the flexibility of a pipelined ADC. It also presents an implementation proposal with simulated results for a reconfigurable pipelined ADC. The proposed ADC architecture is a combination of the conventional pipelined ADC and the cyclic ADC, giving it a very low level of complexity, a high level of component reuse and subst

Waste in form of fat, oil and grease (FOG) is generated where food is prepared or consumed, e.g. in households. If collected properly, the household FOG could be interesting for biogas production. This fraction has been source-separated and collected separately in a residential area in Malmö, Sweden. The biogas potential has been evaluated by mesophilic digestion experiments. Both single-substrate

Canonical bases, also called SAGBI bases, for subalgebras of the non-commutative polynomial ring are investigated. The process of subalgebra reduction is defined. Methods, including generalizations of the standard Gröbner bases techniques, are developed for the test whether bases are canonical, and for the completion procedure of constructing canonical bases. The special case of homogeneous subalg

The type of mixed mode fracture, which is of a main interest for concrete, is a type of fracture, where shear as well as tensile stresses act in a damage zone, which has been created due to pure tensile stresses, and which is perpendicular to the direction of these stresses. While this damage zone still transfers tensile stresses, a shear deformation takes place, which also causes shear stresses.

Popular Abstract in Swedish De ökande kraven på högre datahastigheter inom trådlös kommunikation ställer allt högre krav på både radiosändare och mottagare, då dessa behöver utnyttja fler frekvensband med större bandbredd vid högre frekvenser. Fokus i denna avhandling ligger på högfrekvensdelen av radiomottagaren, som består av lågbrusförstärkare, blandare, och oscillatorer vid mikrovågsfrekvenserThe increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. Tra

I klinisk praxis görs palpation per rektum rutinmässigt på vuxna patienter vid akut buk. Vi utvärderade evidensen för detta genom en systematisk litteratursökning och identifierade 16 relevanta originalstudier. Dessa visade att det saknas evidens för diagnostisk nytta av rektalpalpation vid akut buk, inklusive misstänkt appendicit. Rutinmässig rektalpalpation bör inte göras vid akut buk hos vuxna

Iii analysis-by-synthesis linear predictive coding (AbS-LPC) an LPC synthesis filter is combined with an analysis-by-synthesis search of the excitation signal. The synthesis filter is an estimator for the speech signal given the excitation. However in most AbS-LPC algorithms this estimator has no explicit model of the quantization noise, which is present in the excitation signal. This paper descri

The current research considers the approximate string matching search for important subsequences from DNA sequences, which is essential for numerous bioinformatics computation tasks. We tested several approximate string matching algorithms and furthermore developed one for DNA data. Run times of the algorithms are important, since the amount of data is very large.
