The performance of Markov chain Monte Carlo (MCMC) algorithms like the Metropolis Hastings Random Walk (MHRW) is highly dependent on the choice of scaling matrix for the proposal distributions. A popular choice of scaling matrix in adaptive MCMC methods is to use the empirical covariance matrix (ECM) of previous samples. However, this choice is problematic if the dimension of the target distributi

For many problems in geostatistics, land cover classification, and brain imaging the classical Gaussian process models are unsuitable due to sudden, discontinuous, changes in the data. To handle data of this type, we introduce a new model class that combines discrete Markov random fields (MRFs) with Gaussian Markov random fields. The model is defined as a mixture of several, possibly multivariate,

The log-Gaussian Cox process (LGCP) is a popular point process for modeling noninteracting spatial point patterns. This paper extends the LGCP model to handle data exhibiting fundamentally different behaviors in different subregions of the spatial domain. The aim of the analyst might be either to identify and classify these regions, to perform kriging, or to derive some properties of the parameter

Enligt HSVs rapport ”Kartläggning av distansverksamheten vid universitet ochhögskolor” från 2011 är genomströmningen i landets distansutbildningar betydligt lägre än motsvarande för campusutbildningar. I detta paper kommer jag att belysa fenomenet genomströmning genom att rikta blicken mot MOOCs, en annan typ av nätbaserade kurser än de som vanligtvis diskuteras i sammanhanget. MOOCs erbjuder en m

A method was developed, which drives the selection of appropriate solar control mechanisms based on theanalysis of overheating due to solar heat gains. The aim of the method is to maintain adequate thermalcomfort levels in highly glazed spaces. Two thermal comfort models, Predicted Mean Vote and AdaptiveModel, were chosen to set the thermal comfort boundaries included in the method. Moreover, in o

About 25,3 % of the Mozambican population is suffering from undernourishment even though a sufficient amount of food and specifically fruits are produced. Post-harvest losses are estimated to 25 % to 40 % and part of the production is not even harvested due to a short season. A solution has to be found to improve fruit preservation and allow the population to consume what is harvested later. Dryin

Solar fruit drying has the potential to reduce food insecurity in developing nations. One possible technique for drying fruit is to use solar dryers. This technique is easy to use without requiring high investments. However, the drying technique can be challenging. One problem is that the drying rate could be different depending on where in the dryer the process takes place. At the beginning of th

Historian David Lowenthal (1985) has pointed out the past is often perceived and represented as “a foreign country” in which cultural heritage is implicitly understood to be bound to geographical territories and associated notions of what it implies to have roots, an identity, and a place in which to belong. This is the paradigmatic background against which so many heritage museums have been found

Seattle is currently the fastest growing city in the United States attracting a large pool of young international professionals – many of whom are working in the IT industry. However, Seattle is also home to a large Nordic community, immigrants once attracted by the agricultural, forestry, and fishing industries. At present however, the city is pulling in a highly educated young Nordic population

In the last decade, museums that were established in the 20th century by immigrants from the five Nordic countries have become increasingly concerned with broadening their audiences and more actively engaging their visitors. Efforts to do this have varied from offering traveling exhibitions produced in the Nordic countries, film programs, festivals, concert series, cocktail hours, culinary confere

This essay compares Han Shaogong’s A Dictionary of Maqiao, Yu Hua’s China in Ten Words, and Xiaolu Guo’s A Concise Chinese-English Dictionary for Lovers from the perspective of philosophy of language. Drawing on Ludwig Wittgenstein’s concept of language games, Zhuangzi’s therapeutic skepticism and J. L. Austin’s theory of speech acts, the essay includes analyses of propaganda as linguistic magic,

To make well-informed decisions on the implementation of solar energy on roofs within the urban environment, a new method was developed and described that could support such decision-making. This method takes both the mutual shading and shading from external objects into account. The method consists of the following six steps: 1) construction of the scene, 2) performance of annual solar irradiatioTo make well-informed decisions on the implementationof solar energy on roofs within the urban environment, anew method was developed and described that couldsupport such decision-making.
