Renblåsning och rotorkanalform

Regenerativ värmeväxling med rotor har ett varvtalsberoende överföringsflöde med frånluft till tilluft, vilket elimineras med ett renblåsningsflöde. Det är inte självklart att en rotor blir renblåst även om renblåsningsvolymen för en rotorkanal är större än rotorkanalens volym. Syftet med denna arbetsrapport är att komplettera en tidigare arbetsrapport med titeln Ren- blåsning med diffusion TV

On Volume Average Relations in Continuum Mechanics, Part II

This paper continues the analysis of volume average relations that was initiated in [1]. In this paper, as well as in the previous one, results from various investigations, presented in the literature, have been reviewed and extended and they have, in some cases, been more precisely stated and rigorously proven. Some of the results in the present paper are believed to be entirely new. The key obje

Supply Chain Security Programs - Comparing business and authority certifications

A new topic that during the last years has come to the attention of researchers is supply chain security. Stakeholders are progressively realizing the importance to join the authority regulations issued by governments (e.g. AEO) to reduce transport delays at Customs or other business certifications (e.g. TAPA) to reduce theft or counterfeiting. However the differences and impacts of security certi

Exception Handling in Recipe-Based Batch Control

Exception handling constitutes a large part of the design and implementation effort in batch production, but so far little work has been carried out to specify this area. This paper proposes an internal model approach for unit supervision using Grafchart. It also discusses exception handling at the recipe level.

Implementing an embedded GPU language by combining translation and generation

Dynamic languages typically allow programs to be written at a very high level of abstraction. But their dynamic nature makes it very hard to compile such languages, meaning that a price has to be paid in terms of performance. However under certain restricted conditions compilation is possible. In this paper we describe how a domain specific language for image processing in Python can be compiled f

Intensification of the biogas process by improved process monitoring and biomass retention

Popular Abstract in Swedish Riksdagen har beslutat att Sveriges energisystem ska ställas om. Målet är ett ekologiskt uthålligt samhälle där staten verkar för en säker, effektiv och miljövänlig tillförsel och användning av energi. Detta görs bland annat genom att stödja forskning om förnybara energikällor. Biogasen är här ett av flera möjliga alternativ och har också utnämnts till det mest miljöanpThe utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. There is a large unused potential of organic waste that is suitable for biogas production and the anaerobic digestion process has the potential of bec

Resilience and Religion in a Forced Migration Context : A narrative study of religiousness as a resilience factor in dealing with refugee experiences from a post-migration perspective of Bosnian refugees in Sweden

Popular Abstract in English Every level of human existence is affected by forced migration. It affects the central aspects of our outer and inner life. However, scientific research focused on the inner life of forced migrants, in particular the one regarding the impacts of forced migration on the most significant values that we hold in life, is often marginalized in forced migration studies. In anUntil recently studies regarding the pathological aspects of refugee experiences have led the psychology field of forced migration, giving little space to positive factors like the resilience and well-being of individuals faced with these adversities. This doctoral thesis emphasizes good health rather than disease and aims at deepening the understanding of resilience and health as opposed to the d

Protection of Photosystem II from Photodamage during the Assembly of the Water Oxidizing Complex

Photosystem II catalyses the light driven oxidation of water, which is a key reaction in oxygenic photosynthesis. This enzyme is, however, exposed to light induced degradation, which decreases the efficiency of the photosynthetic process. The work presented here deals with the situation when photosystem II is at a high risk of photodamage due to impaired electron donation from the water oxidising
