This thesis presents the results of an investigation into BIM standardisation needs and procedural supporting mechanisms that may enable design, construction and operating (DCO) organisations to advance their deployment of Building Information Modelling (BIM) technology, and improve construction project outcomes. To achieve sustainable development requires effective information management. Buildi
The growing complexity of industrial robot work-cells calls for the use of advanced orchestration techniques to promote flexibility and reusability. This paper presents a solution based on service-oriented platforms that endorses the separation of concerns, coordination and execution. The execution is kept inside each individual device and their functionality is exposed via automatic generation of
Aims: To establish a cardiac cell culture model for simulated ischemia and reperfusion and in this model investigate the impact of simulated ischemia and reperfusion on expression of the calcium handling proteins FKBP12 and FKBP12.6, and intracellular calcium dynamics. Methods: HL-1 cell cultures were exposed to normoxia (as control), hypoxia, simulated ischemia (HEDA) or HEDA + reactive oxygen sp
Competition is an integrated part of most civilizations, from sports to education. Often competition arise whether or not it was intended and higher education is no exception from this. Should teachers acknowledge this and try to introduce competition as a part of the course or should they try to prevent competition, even spontaneously arisen competition? In this paper an overview of effects of co
In this chapter a technology for the enhancement of video data obtained at low light levels is presented. The method was inspired by the way in which nocturnal animals adaptively sum intensities, spatially and temporally, to improve vision at night. Due to the low photon count under these conditions the visual input is dark and unreliable, which leads to noisy low contrast images. The noise become
This article describes results of the work on knowledge representation techniques chosen for use in the European project SIARAS (Skill-Based Inspection and Assembly for Reconfigurable Automation Systems). Its goal was to create intelligent support system for reconfiguration and adaptation of robot-based manufacturing cells. Declarative knowledge is represented first of all in an ontology expressed
We present a comparative exploratory analysis of two proximity networks of mobile phone users, the Proximates network and the Reality Mining network. Data for both networks were collected from mobile phones carried by two groups of users. Periodic Bluetooth scans were performed to detect the proximity of other mobile phones. The Reality Mining project took place in 2004-2005 at MIT, while Proximat
Popular Abstract in Swedish Växter påverkar marken rent mekaniskt genom att jordstrukturen ändras när en rot växer, men också kemiskt genom att rötterna utsöndrar organiska molekyler. De organiska molekylerna ökar näringstillgången för mikroorganismerna i marken och därmed ändras tillväxthastigheten och biomassan hos mikroorganismerna. I området runt rötter, rhizosfären, råder det därför en hög miMicrobial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. I have shown that the thymidine and leucine incorporation techniques are w
Resource optimization mechanisms, as admission control and traffic management, require accurate performance models that capture the dynamics of the system during high loads. The main objective of this paper is to develop an accurate performance model for database servers in a telecommunication service management system. We investigate the use of a server model with load dependency. Concurrent requ
Popular Abstract in Swedish Slemhinnorna i näsan, bihålorna, nasofarynx (nässvalgrummet), örontrumpeten och främre delen av mellanörat, är beklädda med celler på vars yta det finns flimmerhår (cilier). De ciliebeklädda slemhinnorna är täckta av ett tunt slemskikt som transporteras av ciliernas rörelser. I slemskiktet fastnar inandade partiklar, bakterier och döda celler, och transporteras av cilieThe aim with this thesis was to investigate effects of vasoactive mediators on mucociliary activity and blood flow in rabbit and human experimental models. Mucociliary activity in vivo and ciliary beat frequency (CBF) in vitro were measured with photoelectric techniques. Blood flow was measured with laser Doppler flowmetry. Substance P (SP) and methacholine increased human nasal blood flow. Pretre
This paper presents a 3rd-order, 3-bit continuous time (CT) Delta-Sigma modulator for an LTE radio receiver. By adopting a return-to-zero (RZ) pulse in the innermost DAC, the modulator shows a reduced sensitivity to loop-delay variations, and the additional loop delay compensation usually needed in CT modulators can be omitted. The modulator has been implemented in a 65nm CMOS process, where it oc
Popular Abstract in Swedish Kost, livsstil, antioxidanter och riskfaktorer för cancer De flesta forskare är överens om att våra matvanor spelar en betydande roll för risken att insjukna i cancer. Däremot är forskarna inte överens om vad och hur man bör äta för att förebygga cancer. En populär teori under det senaste decenniet har varit den så kallade antioxidantiahypotesen. Man har förstått att This thesis examines associations between a number of epidemiological or biological markers of cancer risk and oxidative stress, in order to achieve a better understanding of how diet, lifestyle, and genetic factors contribute to the occurrence of oxidative stress. Data from the Malmö Diet and Cancer (MDC) cohort was used. The MDC study is a population-based cohort study which uses a detailed modi
This paper describes an attempt to provide more intelligence to industrial robotics and automation systems. We develop an architecture to integrate disparate knowledge representations used in different places in robotics and automation. This knowledge integration framework, a possibly distributed entity, abstracts the components used in design or production as data sources, and provides a uniform
Evolutionary molecular studies of island radiations may lead to insights in the role of vicariance, founder events, population size and drift in the processes of population differentiation. We evaluate the degree of population genetic differentiation and fixation of the Canary Islands blue tit subspecies complex using microsatellite markers and aim to get insights in the population history using c
Popular Abstract in Swedish IgA-nefropati (IgAN) är den vanligaste formen av primär inflammation av njurarna och Henoch-Schönlein purpura (HSP) den vanligaste formen av kärlinflammation i barndomen. HSP kan också drabba njurarna och kallas då Henoch-Schönlein nefropati (HSN). Orsaken till båda sjukdomar är inte helt klarlagd ännu. Båda kännetecknas av vävnadsinlagringar med immunoglobulin A (IgA)IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis and Henoch-Schönlein purpura (HSP) the most common form of vasculitis in childhood. HSP may affect kidneys, a complication termed Henoch-Schönlein nephropathy (HSN). Renal pathology in HSN resembles that seen in IgAN. The pathogenesis of IgAN and HSP is so far unclear. Both are characterized by tissue deposits of undergly
Model-based systems in control are a means to utilize efficiently human knowledge and achieve high performance. While models consisting of formalized knowledge are used during the engineering step, running systems usually do not contain a high-level, symbolic representation of the control and most of its properties, typically named numerical parameters. On a system level and beyond the plant data,
Combining attribute grammars with object-oriented programming supports a new kind of declarative programming, allowing compilers to be built in a highly extensible manner. By leveraging a base compiler, extended languages can be supported at a relatively low cost. Recent work shows the applicability of the technique to general-purpose programming languages like Java. In this article, we illustrate
The objective of the study was to test whether live plants on computer workstations with and without window view had restorative effects. Guided by Stress Recovery Theory and Attention Restoration Theory a mixed randomized experiment was conducted exploring restorative effects of plants, including mediating effects of perceived fascination. Eighty-five participants carried out a 1-hr work session
Alterations in cellular pathways related to both endocrine and vascular endothelial growth factors (VEGF) may contribute to breast cancer progression. Inhibition of the elevated levels of these pathways is associated with clinical benefits. However, molecular mechanisms by which endocrine-related pathways and VEGF signalling cooperatively promote breast cancer progression remain poorly understood.
