A non-Gaussian time series with a generalized Laplace marginal distribution is used to model road topography. The model encompasses variability exhibited by a Gaussian AR(1) processwith randomly varying variance that follows a particular autoregressive model that features the gamma distribution as its marginal. A simple estimation method to fit the correlation coefficient of each of two autoregres

Popular Abstract in Swedish Denna avhandling skall främst ses som ett bidrag till diskussionen om en framväxande ny "kulturaliserad" ekonomi. Avhandlingens syfte är att genom att analysera produktion och konsumtion av mejerivaror följa hur en ny ekonomi formas och tar plats i vardagen samt se vilka kulturella värderingar och föreställningar som skapas i denna process. Den teroetiska inspirationen This dissertation is to be regarded as a contribution to the discussion about a "cultural economy". The aim of the study is to gain a perspective as to how a new economy can be shaped and take its place in everyday life, as well as identify the cultural values and ideas created in the process, by analysing the production and consumption of dairy products. Theoretical inspiration is derived from st

The Las Cuevas site is a Maya administrative and ceremonial center active during the latter part of the Late Classic period (700-900 AD) in Western Belize. It is of particular interest because a large cave resides directly beneath the largest temple in the site core. This paper presents the use of phase shift variation laser scanning technology (Faro Focus 3D) for the acquisition of the cave’s net

Kapitlet behandlar 3 aspekter av globalisering: (1) Det växande antalet internationella organisationer, som avsatt en omfattande internationell tjänstemannakår; (2) internationella frågors intrång på nationella administrativa organs dagordning; (3) icke-statliga akörers vidgade roll i det internationella umgänget.

1. Background The workgroup of Traffic Psychology is concerned with the social, behavioral, and perceptual aspects that are associated with use and non-use of bicycle helmets, in their various forms and under various cycling conditions. 2. Objectives The objectives of WG2 are to (1) share current knowledge among the people already working in the field, (2) suggest new ideas for research on and eva

This paper treats fault detection in DC distributed power systems, with emphasis on ground faults. The difficulty of detecting ground faults arises from the fact that the AC sources and loads are ungrounded or have heavy impedance to ground, on the converter side, to effectively block zero sequence currents otherwise flowing between the AC systems. A grounding scheme for the DC distribution system

Popular Abstract in Swedish Aneurysm är ett sjukdomstillstånd som är känt sedan ca 2000 år före vår tideräkning, och bukaortaaneurysm (bråck på stora kroppspulsådern i buken) beskrivs i publikationer från 1500-talet. På 1800-talet försökte man sig på att behandla med ligering, tyvärr med dåligt resultat, och först på 1920-talet beskrivs den första lyckade ligeringen. Behandling med graftrekonstrukThe incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. AAA:s, range 40-55 mm were studied in relation to gender. No difference in AAA diameter was found. However, body surfac

Popular Abstract in Swedish Fysik försöker förklara naturfenomen med matematiska beskrivningar som beror på systemet som studeras. Även om vi till exempel vet hur man beskriver rörelsen av ett fallande äpple, blir övervägandet av detaljer som ett fallande äpple knappast relevant när man försöker beräkna jordens rörelse runt solen. Å andra sidan spelar partikelfysik ingen roll i beskrivandet av äppThis thesis considers numerical simulations of high energy particle collisions, and improvements in the description of multiple collimated jets of hadrons in collision events in particular. In the event simulation software called event generators, the structure of multi-jet events is determined through an interplay of the input calculation, parton showers and phenomenological hadronisation models.

We present a family of protograph based LDPC codes that can be derived from permutation matrix based regular (J,K) LDPC convolutional codes by termination. In the terminated protograph, all variable nodes still have degree J but some check nodes at the start and end of the protograph have degrees smaller than K. Since the fraction of these stronger nodes vanishes as the termination length L increa
