A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. This thesis aims at testing different methods for classifying UAV images from an agricultural crop site in the so

BACKGROUND: Secondary peritonitis is a severe condition with a 20-32% reported mortality. The accepted treatment modalities are vacuum-assisted closure (VAC) or primary closure with relaparotomy on-demand (ROD). However, no randomised controlled trial has been completed to compare the two methods potential benefits and disadvantages.METHODS: This study will be a randomised controlled multicentre t
Title: Overreaction on the Swedish stock market Seminar date: 2008-01-30 Course: Nek K01- Bachelor Thesis in Economics (15 ETCS) Authors: Advisor: Oskar Herbe and Ludvig Persson Hossein Asgharian Key Words: Overreaction, Anomalies, Market Efficiency, Contrarian investment strategies Purpose: The purpose of this thesis is to test if the overreaction hypothesis as originally described by De Bondt an
The ionization dynamics of Ar and Xe clusters irradiated with intense vacuum ultraviolet light from a free-electron laser is investigated using photoelectron spectroscopy. Clusters comprising between 70 and 900 atoms were irradiated with femtosecond pulses at 95 nm wavelength (similar to 13 eV photon energy) and a peak intensity of similar to 4x10(12) W/cm(2). A broad thermal distribution of emitt
BackgroundOak moss absolute, an extract from the lichen Evernia prunastri, is a valued perfume ingredient but contains extreme allergens. ObjectivesTo compare the elicitation properties of two preparations of oak moss absolute: classic oak moss', the historically used preparation, and new oak moss', with reduced contents of the major allergens atranol and chloroatranol.

A system with property-close source-separation of thirteen different solid household waste fractions in a residential area in southern Sweden, including the implementation of new systems for source-separation of food waste, waste electric and electronic equipment, hazardous waste and fat, oils and grease was monitored over a 2-year period. Continuous weighing of disposed waste and repeated waste c

Breast cancer is a truly heterogenous disease, reflected in the existence of a wide spectrum of phenotypic subsets of tumours with varying intrinsic aggressiveness as well as ability to respond to a given treatment. Recent advances in large-scale genomic and proteomic screening techniques have confirmed this heterogeneity also at a molecular level, but there is still a bottleneck to be overcome be
The free intracellular Ca2+ concentration ([Ca2+]i) was measured simultaneously with isometric force in strips of guinea-pig mesotubarium using the Fura-2 technique. [Ca2+]i and force were maximal at a relatively low (30 mM) concentration of extracellular K+ ([K+]o), and declined at 90 and 140 mM K+. Plateau values of both [Ca2+]i and force were higher in the presence of 5.10(-6) M ryanodine, indi
Popular Abstract in Swedish LUNGVOLYMER OCH LUNGMEKANIK HOS BARN UNDER ANESTESI Avhandlingen är avsedd att fylla luckor i vårt vetande vad gäller normal utveckling av lungvolymer och lungans elasticitet hos barn, från tidiga spädbarnstiden till tonåren. Speciellt har tidigare funnits en brist på data hos barn yngre än skolåldern. Undersökningarna gjordes i narkos och under muskelavslappning. MätnThe thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. Measurements: · Absolute lung volume was obtained with a tracer gas method (sulfur hexaf
We report on the measurement of the inclusive Upsilon(1S) production in Pb-Pb collisions at root s(NN) = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its mu(+)mu(-) decay channel with the ALICE detector at the Large Hadron Collider. Astrong suppression of the inclusive Upsilon(1S) yield is observed with respect to pp collisions scaled by the num
Subacute inhalation study (1 week or 2 weeks) is an important process for screening out inhaled compounds causing lung irritation. To investigate whether the lung weight can be used as an indicator for acute lung injury, we have analyzed retrospectively the lung weight data from 30 studies in rats exposed to dry powder inhalation. The lung weight change was correlated with lung histopathology in t
ABSTRACT: BACKGROUND: Previous studies on healthy people show that vinegar delays gastric emptying and lowers postprandial blood glucose and insulin levels. The aim of this study was to investigate the effect of apple cider vinegar on delayed gastric emptying rate on diabetes mellitus patients. METHODS: Ten patients with type 1 diabetes and diabetic gastroparesis, including one patient who had und
Popular Abstract in Swedish Denna avhandling handlar om hur ljus kan användas för att detektera, diagnosticera och behandla olika medicinska sjukdomstillstånd. Det vi dagligen kallar ljus är bara en liten del av det elektromagenetiska spektret, nämligen den del vi kan uppfatta med våra ögon. Elektromagnetisk strålning med andra våglängder används i stor utsträckning för klinisk diagnostik. RöntgenIn this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. However, the goal is naturally to develop methods useful in the clinic, and thus the emphasis in this thesis has been put on in vivo examinations. Raman spectro
This dissertation focuses on the changes in the organization of the production process that occurred at Volvo Cars and Volvo Trucks in the early 1990s. The changes were directed at the established division of labor – both vertical and horizontal – between different groups of employees: managers, foremen, white and blue-collar workers. The questions posed are primarily concerned with the changes fo
The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. An increased risk of ope
Stem cells have qualities that clearly distinguish them from all other cells. Capabilities like self-renewal, differentiation and migration make them truly powerful. This thesis deals with different aspects of stem/progenitor cells in relation to cancer. Certain types of neural progenitor cells (NPCs) have been shown to possess a potential of tracking glioma cells in the brain. This makes them pot
Assessment of health-related quality of life (HRQoL) in haemophilia is important in order to provide information for clinical decision making and to verify the impact of haemophilia on patients and their families. Advances in haemophilia care and prophylactic treatment have improved HRQoL for the patients and where treatment is available, patients with haemophilia have almost reached the same life
