In schools the temperature of the indoor air is one of the most important factors in terms of the indoor climate. The resulting indoor air temperature is depending on many factors; the temperature of the supply air being one of the more significant one. One fan-assisted natural ventilation system includes a supply air system where the outdoor air should be passively heated respectively cooled when
The paper gives an overview of ongoing research and research performed during recent years at Växjö University, Sweden, within a PhD study. Results from various experimental and numerical studies relating to the behaviour of dowel-type joints are presented.
The results are discussed in relation to the expected behaviour of the joints according to the current version of EC5. Possible impli
Stories can be told in different ways, and through various versions reflect various aspects of reality. Realities encountered in different ways are remembered differently, and the different memories create new memories and new remembered realities. So the question in this paper is: How do people in Sweden and Norway tell the stories of the two great Orthodox saints St Anna of Novgorod and St Olav?
Gestures, i.e. the symbolic movements that speakers perform while they speak, form a closely interconnected system with speech, where gestures serve both addressee-directed (‘communicative’) and speaker-directed (‘internal’) functions. This article aims (1) to show that a combined analysis of gesture and speech offers new ways to address theoretical issues in second language acquisition (SLA) and
We study the effects of local vertex corrections to the self-energy of the electron gas. We find that a vertex derived from time-dependent density-functional theory can give accurate self-energies, provided, however, a proper decay at large momentum transfer (large q) is built into the vertex function. (The local-density approximation for the vertex fails badly.) Total energies are calculated from
This paper shows a novel methodology to reduce the power consumption and complexity in unrolled CORDIC architectures. It is a methodology is based on removing adder and subtractor stages starting from the first stage. The stages are replaced with a number of MUXes. Three to four stages can be removed with substantial reduction in complexity and power consumption. The methodology is applicable on C
In this paper a model reduction algorithm in the nu-gap metric is considered. The metric was originally developed to evaluate robustness of a controller for a given plant. In fact, the nu-gap metric induces the weakest topology in which stability is a robust property. All in all the nu-gap metric is perhaps the best metric to evaluate the distance between two systems in a closed loop setup. In the
The myriad of interpersonal relationships in tourism, between tourists, between tourists and locals, and between tourists and the service providers, are essential, generic components of the tourist experience. However, interpersonal relationships are emerging as a commercial value in the tourism industry as well, expressed for example in rural commercial home type of businesses, and in wellness-or
