Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue. In order to minimize the loss of revenue due to disturbances in utilities, the optimal supply of utilities
Popular Abstract in Swedish I avhandlingen utvecklas en begreppsapparat som syftar till att utvidga vetenskapens möjligheter att studera människors formaliserade praktik i såväl religiösa som profana sammanhang. Begreppet ritual blir en term att se och tänka med. Författaren applicerar sin begreppsapparat på de medeltida isländska släktsagorna där skapandet av allianser mellan personer är ett viktTo make it possible to classify an action as a ritual act we need to know exactly what constitutes it. In this thesis I try, with the aid from literature of the field called ritual studies and the sagas of Icelanders, to sort out what these constituent elements best should consist of if we want to use the term ritual as an analytical tool in the production of knowledge with scientific criteria. Ri
SO2 dry deposition was studied over short vegetation, in Portugal, by means of the concentration gradient method. The experimental study involved one first phase of long-term measurements carried out in a grassland and, subsequently, a second period of several 1997 intensive field campaigns performed in three places representing different climate and surface conditions. Temporal and spatial patter
Structural best management practices (BMPs) are now commonplace for stormwater management in new suburban developments; however, their installation in older central areas is limited. Here, the effect of disconnecting impervious areas from a combined sewer in favour of a new open stormwater system is investigated. The site, an inner city suburb of Malmo, Sweden, consists of council offices and apar
During the Quaternary period, ice sheets centred over the Barents and Kara seas expanded several times onto mainland Russia and blocked northflowing rivers, such as the Yenissei, Ob, Pechora and Mezen. Large ice-dammed lakes with reversed outlets, e.g. toward the Caspian Sea, formed south of these ice sheets. Some lakes are reconstructed from shorelines and lacustrine sediments, others mainly from
To study and simulate cognitive development, it is useful to find a natural domain where many cognitive functions are needed and, but where the complexity of the environment and task is reasonable. We suggest that childrens games constitute a suitable domain. The ability to play is a very fundamental part of children's daily life and it is crucial for the future development of our behaviors in Bek
This report describes the work carried out within the research project ``Merging Real-Time and Control Theory for Improving the Performance of Embedded Control Systems''. The overall objective of the work has been to develop integrated control and scheduling methods for improving the performance of real-time control systems with limited resources. The work has fallen into three categories. First,
The paper focuses on the changing economic geographies of the outer city of Copenhagen. The outer city is not a well-defined place but can be understood as a set of processes transforming the urban economic landscape outside the built- up area. Several central and interrelated economic processes transform the outer city. The paper examines the changing industrial dynamics and location spaces withi
Popular Abstract in Swedish Det mesta av det genetiska materialet i en eukaryot cell finns samlat till kärnan och är organiserat i kromosomer. Varje gång en cell delas kopieras kromosomerna så att de båda resulterande cellerna får ett bibehållet kromosomantal. Den mekanism som styr denna replikeringsprocess förmår dock inte kopiera de yttersta kromosomändarna, vilket resulterar i att dessa blir koTelomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. However, they contain a sequence resembling the consensus binding sequence of the major t
Abstract in UndeterminedA comparison is made of battery charger topologies for electric vehicles. The chargers are all off-board, and capable of active power line conditioning and bi-directional power flow to compensate local utilities during peak power loads. The active power line conditioning capability is important, since an increase of battery chargers based on ordinary diode rectifiers would
The present dissertation delineates how the fairy tale character, Little Red Riding Hood, has appeared in different screen versions. It is a thematic and historical analysis of the development of film versions and other traces of the story 1901 to 2001, focussing particulary on the representation of Red Riding Hood herself. The story of this little girl, mostly dressed in different red garments, i
In breast tomosynthesis1 (BT) a number of 2D projection images are acquired from different angles along a limited arc. The imaged breast volume is reconstructed from the projection images, providing 3D information. The purpose of the study was to investigate and optimize different reconstruction methods for BT in terms of image quality using human observers viewing clinical cases. Sixty-six cases
Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Kadmium är en giftig metall vilken finns i mat som vi rekommenderas äta mycket av, exempelvis sädesprodukter, grönsaker och skaldjur. Våra matjordar är kontaminerade med kadmium och föroreningen kommer att kvarstå under mycket lång tid framöver. Kadmium skadar framförallt njurarna och skelettet och kan antagligen även orsaAbstract: Cadmium (Cd) is ubiquitous in the environment. Human exposure in non-smokers occurs mainly via intake of healthy food like vegetables, cereals, and shellfish. Adverse health effects on kidney and bone at low-level environmental Cd exposure are well-documented in adults. There is considerable inter-individual variation in both metabolism (toxicokinetics) and toxicity (toxicodynamics) of C
In this paper, we study event-based PID control from an optimal stochastic control perspective. The purpose is to better understand what implementation features are critical for achieving good event-based PID performance. For this end, we formulate an LQG control design problem for a double integrator process with an integral disturbance, where the solution is an ideal PID controller. We then cons
Cyclin-dependent kinases (CDKs) are activated by cyclins, which play important roles in dictating the actions of CDK/cyclin complexes. Cyclin binding influences the substrate specificity of these complexes in addition to their susceptibility to inhibition or degradation. CDK/cyclin complexes are best known to promote cell cycle progression in the mitotic cell cycle but are also crucial for importa
Under de två senaste decennierna har vattenfärgen ökat dramatiskt i södra Sverige. Vattenfärgen bestäms främst av koncentrationen av humuspartiklar. Humus påverkar råvattenkvalitén och kostnaden för att producera dricksvatten har ökat markant p.g.a. de ökande humushalterna. Det är därför av stort intresse för samhället att kartlägga vad som kommer hända med DOC koncentrationerna i framtiden och peDuring the last two decades the watercolour have increased dramatically in southern Sweden. The watercolour is manly determined by the DOC (Dissolved Organic Carbon) concentration. DOC affects the raw water quality, and because of the increasing trends, the cost for producing drinking water of high quality has risen considerably. It is therefore of great interest for society to understand what wil
In his thesis I have analyzed the US-led invasion and occupation of Iraq, as well as the widespread opposition and armed resistance against the former, starting off from the assumption that the actions and policies of the occupation in many ways fosters popular opposition and armed resistance. I have analyzed the actions and policies of the occupation since the invasion as well as the aims and und
Populärvetenskaplig sammanfattning: Jordens klimat står under ständiga variationer och förändringar, och det är inte alltid lätt att sära på orsak och verkan bland den mängd av faktorer som styr klimatet. För att kunna reda ut ursprunget till de förändringar som sker, måste de bakomliggande processerna vara väl kända. Sedan är det möjligt att genom matematiska modeller uppskatta de individuella prSeveral studies have analysed the relationship between Normalised Difference Vegetation Index (NDVI) and radiative surface temperature. A main goal for most studies have been to find the best method for carrying out land cover classifications and to study land cover changes, based on a combination between the two parameters. Since atmospheric components have a significant influence on both paramet
