Consider a stationary normal process ξ(t) with mean zero and the covariance function r(t). Properties of the sample functions in the neighborhood of zeros, upcrossings of very high levels, etc. have been studied by, among others, Kac and Slepian, 1959 [4] and Slepian, 1962 [11]. In this paper we shall study the sample functions near local maxima of height u, especially as u → -∞, and mainly use si
The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1.6 litre single cylinder engine based on a heavy duty six cylinder Volvo, was used for the tests. As follows the experimental work was
Popular Abstract in Swedish Konceptet fjärrvärme inbegriper central värmeproduktion från vilken värme distribueras ut till de enskilda förbrukarna via ett rörsystem. Ett grundläggande krav, med hänsyn till fjärrvärmens konkurrenskraft, är att vinsten som görs i den storskaliga värmeproduktionen, jämfört med lokal värmeproduktion, överstiger kostnaderna för värmedistributionen. DistributionskostnadThe concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. Since the distribution cost per delivered kWh increases as the heat density of an area
Cancer represents a collection of malignancies characterized by an aberrant expansion of cells. This unrestrained growth is the result of the acquisition of several pro-survival features and the evasion of cellular fail-safe mechanisms, collectively known as the hallmarks of cancer. In the clinical setting, disease management has heavily relied on the sole targeting of malignant cells but, except
The sustainable use of groundwater relies on building up three stages: exploration, development and management. The exploration is crucial to understand the capabilities and limitations of aquifer units; e.g. volume of available water and potential yield, distinction of recharge and discharge zones, and the groundwater quality are developed in this stage. In the Altiplano, groundwater is probably
Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. Most natural organic waste can be used in anaerobic digestion. In developing count
Investments in infrastructure projects in developing countries are often seen as risky by private investors and local capital markets are not fully developed. Consequently, financial resources and guarantees are often to a large extent provided by financial institutions. Financial and economic analysis is important in assessing infrastructure investment proposals in order to assure that they are f
The rapid population growth in China during the last decades has put an enormous pressure on cultivation production and water supply. Many regions in China are therefore facing water scarcity and shortage of arable land. One of such regions is Gansu and it is considered as the driest and poorest province in China. This arid and semi-arid region is signifying a very uneven annual precipitation patt
This study reports an impact evaluation carried out for a large-scale research infrastructure, the Brazilian Sirius Synchrotron Light Source, one of two fourth-generation synchrotron light sources in the world. We focus on the economic impacts and spillovers resulting from highly qualified procurements presented to different types of suppliers who participated in the design and construction proces

Importance: The concept of embolic stroke of undetermined source (ESUS) unifies a subgroup of cryptogenic strokes based on neuroimaging, a defined minimum set of diagnostic tests, and exclusion of certain causes. Despite an annual stroke recurrence rate of 5%, little is known about the etiology underlying recurrent stroke after ESUS. Objective: To identify the stroke subtype of recurrent ischemic
This thesis contributes to the quantitative finance literature and consists of four research papers.Paper 1. This paper constructs a hybrid commodity interest rate market model with a stochastic local volatility function that allows the model to simultaneously fit the implied volatility of commodity and interest rate options. Because liquid market prices are only available for options on commodity
Magnetkameran är en fantastisk medicinsk bildutrustning som kan producera detaljerade bilder av insidan av kroppen. Förutom bilder av vävnaden och dess struktur så kan magnetkameran också användas till att mäta olika egenskaper hos vävnaden. Om en vävnadsegenskap mäts i varje bildpixel så kan den resulterande bilden (parameterkartan) visas och användas för medicinsk bedömning, vilket kallas för kvThe magnetic resonance imaging (MRI) scanner is a remarkable medical imaging device, capable of producing detailed images of the inside of the body. In addition to imaging internal tissue structures, the scanner can also be used to measure various properties of the tissue. If a tissue property is measured in every image pixel, the resulting property image (the parameter map) can be displayed and u
The aim of this work was to develop a model suited for detailed studies of aerosol dynamics, gas and particle phase chemistry within urban plumes, from local scale (1x1 km(2)) to regional scale. This article describes and evaluates the trajectory model for Aerosol Dynamics, gas and particle phase CHEMistry and radiative transfer (AD-CHEM). The model treats both vertical and horizontal dispersion p
Over the last few decades, increasing rates of change in the structure and function of ecosystems have been brought about by human modification of land cover, of which a major component is vegetation. Metrics derived from linear regression models applied to high temporal resolution satellite data are commonly used to estimate rates of vegetation change. This approach implicitly assumes that vegeta
Background: Several attempts to increase the locoregional control in locally advanced lung cancer including concurrent chemotherapy, accelerated fractionation and dose escalation have been made during the last years. As the EGFR directed antibody cetuximab has shown activity concurrent with radiotherapy in squamous cell carcinoma of the head and neck, as well as in stage IV NSCLC combined with che
Popular Abstract in Swedish Luftburna partiklar från transportsektorn och energiproduktion kan ge upphov till negativa hälsoeffekter hos människor och påverka det globala klimatet. Partiklarnas kemiska och fysikaliska egenskaper förändras när de åldras i atmosfären och ny partikelmassa kan bildas från ämnen som tidigare var i gasfas. Det övergripande syftet med den här avhandlingen är att öka kunsEmissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. The overall aim of this thesis was to investigate how atmospheric transformation and combustion conditions a
