Vad tänker du på när du hör ordet solprognos? För vissa är det viktigt i planeringen av semestern, andra kanske för att skydda sig mot farlig UV-strålning. Vad många inte vet är att solprognoser är en viktig komponent i vårt energisamhälle där förnyelsebara energikällor som solkraft och vindkraft ökar kraftigt runt om i världen. Att göra träffsäkra prognoser för inkommande solstrålning har dock viSolar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for

Den mer än 700 m mäktiga lagerföljden på Gotland är erosionsresterna av vidsträckta karbonatplattformar som bildades i den Baltiska bassängen under silurperioden. Detta arbete fokuserar på stratigrafin och bergarterna i borrkärnan Tallbacken-1 som togs upp vid Stora Vede av Sveriges geologiska undersökning år 2006. Analys av kalkstenens mikrofacies tillsammans med analys av geofysiska data (gamma

Sustainability has become a leading concept in development policy and practice. The most recognized definition of sustainable development was coined by the Brundtland Commission in 1987. It provides normative guidelines for a common sustainability agenda and sees responsibility for, and benefits from, this common effort as universal. The agenda addresses stakeholders worldwide and its all-encompas

Because of increasing pressures on marine life and habitats, the overall health of the global ocean has over the latter years received attention internationally. It is therefore of relevance to analyse how the type of human-nature relationship towards the ocean is presented through what can be coined as Blue Growth. The aim of this research is to critically discuss what human-nature relationships

The purpose of this paper is to provide a foundation for modelling train delays as multivariate time series. A pertinent issue with this kind of analysis is that the individual time series do not follow the Gaussian normal distribution. Since the normal distribution constitutes an assumption of classical time series methods, these cannot be applied blindly to the data. The solution explored by the

Building sustainable, collaborative solutions to contemporary sustainability challenges requires a new generation of future professionals or ‘change-agents,’ the engagement of non-academic stakeholders, and academic facilitation. Educational reform is needed in order to enhance students’ competencies in becoming effective sustainability professionals. Effective collaborative platforms have the pot

Kunskap om markens uppbyggnad är viktig både för konstruktions och prospekteringsändamål. Geofysiska undersökningsmetoder kan användas för att skapa en överblick att basera vidare undersökningar på. I den här studien används likströms resistivitet och inducerad polarisation, IP. Datan är inverterad med en Cole-Cole modell i programmet ÅrhusInv och använd för att karakterisera berggrunden vid ÖnnesFor both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. In this study direct current resistivity and induced polarization data, inverted with a Cole-Cole model in program AarhusInv, are used to characterize the bedrock at Önneslöv in Scania,

The language learning process by third age learners has recently become a field of interest for linguistic research. However, it has been studied mostly regarding psychological and cognitive considerations (stress, motivation, attention, memory, etc.), rather than according to language internal factors. The present study aims to provide a contribution by investigating the mastery of Italian gramma

Society is facing diverse vital societal challenges, which has led to an increased focus on how policy makers should target these challenges. Innovation policies have gone through a development from firm based R&D towards a more systematic and transformative approach towards innovation. This research has investigated how policy instrument in the form of innovation programs have been experience
