The paper presents novel studies on the impact of different ignition control parameters on combustion stability and spark plug wear. First, experimental results from a 32.4-liter biogas fueled large bore single cylinder spark ignition engine are discussed. Two different ignition systems were considered in the experiment: a DC inductive and an AC capacitive. The spark plugs used in the experiment w

To reduce the load on the UAV operator during long-term search and rescue missions, an on-board automatic system is considered that generates control signals for positioning an additional video camera with a narrow field of view. The requirements for the system of automatic detection of the area of interest are defined. Various methods for detecting objects in images are considered, analyzed and c

Background: Cleft lip with cleft palate (CLP) is a congenital condition that affects both the oral cavity and the lips. This study estimated the prevalence and mortality of CLP using surveillance data collected from birth defect registries around the world. Methods: Data from 22 population- and hospital-based surveillance programs affiliated with the International Clearinghouse for Birth Defects S

Enabling resilient autonomous motion planning requires robust predictions of surrounding road users' future behavior. In response to this need and the associated challenges, we introduce our model titled MTP-GO. The model encodes the scene using temporal graph neural networks to produce the inputs to an underlying motion model. The motion model is implemented using neural ordinary differential equ

Given their flexibility and encouraging performance, deep-learning models are becoming standard for motion prediction in autonomous driving. However, with great flexibility comes a lack of interpretability and possible violations of physical constraints. Accompanying these data-driven methods with differentially-constrained motion models to provide physically feasible trajectories is a promising f

Aim: To determine the prevalence of neurobehavioral symptoms at 6.5 years in children born extremely preterm (EPT, <27 weeks' gestation). Methods: Population-based cohort study of infants born EPT in Sweden from 2004 to 2007. Of 486 survivors 375 were assessed and compared with 369 matched term-born controls. EPT children free from neurosensory and intellectual disabilities (neurodevelopmental dis

Deltas play a critical role in the ambition to achieve global sustainable development given their relatively large shares in population and productive croplands, as well as their precarious low-lying position between upstream river basin development and rising seas. The large pressures on these systems risk undermining the persistence of delta societies, economies, and ecosystems. We analyse possi

Abstract in UndeterminedThe success of the Wii and of the iPhone together with the persisting problem of displaying information on the small screens of mobile devices is currently pushing the development of non-visual interaction channels such as gestures, tactile/haptic interaction and sound. This development presents both potential and risk, since new channels of interaction may result either in

We present a comparative analysis of the unfolding and inactivation of three cutinases in the presence of guanidine hydrochloride (GdnHCl) and bis(2-ethylhexyl) sodium sulfasuccinate (AOT). Previous investigations have focused on the cutinase from Fusarium solani pisi (FsC). In addition to FsC, the present study includes the cutinase from Humicola insolens (HiC) and a mutant variant of HiC (mu HiC

Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos

Hållbar utveckling är idag ett centralt begrepp och en vision inom alla tänkbara samhällsområden. Det utgör kärnan i svensk planeringslagstiftning. Såväl kommunalt översiktsplanearbete som regionalt utvecklingsarbete har tydliga perspektiv för en hållbar utveckling. Sveriges samhällsorganisation kan karaktäriseras av ett timglas med en stark stat, starka kommuner och en svag regional nivå i mitten

The etiology of exercise-induced rib stress fractures (RSFs) in elite rowers is unclear. The purpose of the study was to investigate thoracic muscle activity, movement patterns and muscle strength in elite rowers. Electromyographic (EMG) and 2-D video analysis were performed during ergometer rowing, and isokinetic muscle strength was measured in seven national team rowers with a history of RSF and

Context. Extremely metal-poor (EMP) stars preserve a fossil record of the composition of the ISM when the Galaxy formed. It is crucial, however, to verify whether internal mixing has modified their surface composition, especially in the giants where most elements can be studied. Aims. We aim to understand the CNO abundance variations found in some, but not all EMP field giants analysed earlier. Mi

Non-linearity in the energy response of a Si p-i-n charged particle detector has been studied for incident particles with Z(1) between 3 and 26, and energies between 0.1 and 0.7 MeV per nucleon. Although the data closely followed a straight line relations, fitting of the data to a third order polynomial revealed that the response exhibited a persistent curvature that acted to reduce the energy int

The differences in fuel consumption and exhaust emissions for residential areas with different street network designs were investigated. Five areas with three different designs, including a traditional grid network and designs feeding the traffic in from a surrounding street and from a centrally located street, were considered. Differences in total fuel consumption and amount of exhaust emissions

This paper presents an investigation method for studying cascading effects in incidents, which is to some extent lacking in the scientific literature. Several incident investigation methods are reviewed and used to influence the presented method. The usefulness of the method is demonstrated in a case study for a recent event in Sweden, a severe flooding event in the city of Malmö in south of Swede

Popular Abstract in Swedish Vad innebär politik efter det internationella? Många samtida perspektiv på internationell politik konvergerar i synen på 'det internationella' som en överspelad idé, men divergerar i synen på vilken typ av politik som växer fram i dess ställe. Den moderna staten har varit avgörande för betydelsen av säkerhet, territorialitet och auktoritet - begrepp konstituerande för iWhat does a politics after the international mean? Many strands of contemporary scholarship converge on the image of the international as obsolete, but strongly diverge on the contours of the kinds of politics that are superseding it. The modern state has been pivotal to the meaning of security, territory and authority?concepts central to the idea of the international?but they do not necessarily h
