heory predicts that electrons emitted from independent electron sources (metallic contacts) can nevertheless interfere. This interference is manifest in an exchange contribution to the shot noise correlation of currents at different contacts of a mesoscopic conductor. A geometry has been proposed in which second order (single particle) interference due to superposition of amplitudes is absent but
Background: Clearance of tissue granulocytes is central to the resolution of airway inflammation. To date the focus has been on apoptotic mechanisms of cell removal and little attention has been given to alternative processes. The present study explores transepithelial migration as a mechanism of cell clearance. Method: Guinea pig tracheobronchial airways where eosinophils are constitutively pres
In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. Multiservice broadband networking generally refers to the ability to handle widely disparate traffic streams s
The objective of this paper is to apply the Virtual Reference Feedback Tuning (VRFT) to Multiple-Input Multiple-Output (MIMO) control strategies in wastewater treatment plants (WWTPs). Using the Benchmark Simulation Model No. 1 (BSM1) as a case study, the proposed data-driven approach provides reduced-order controllers only using a batch of input-output data points (i.e. manipulated variable-contr
Structural and electronic properties of a small anatase TiO2 nanocrystal sensitized by the ruthenium dye N3 (Ru(4,4‘-dicarboxy-2,2‘-bipyridine)2(NCS)2) have been investigated using density functional theory (DFT) with support from Hartree−Fock (HF) and time dependent DFT (TD-DFT) calculations. Significant structural adjustments of both the dye and the nanocrystal are predicted to be induced by the
Current developments in genetics and genomics entail a number of changes and challenges for society as new knowledge and technology become common in the clinical setting and in society at large. The relationship between genetics and ethics has been much discussed during the last decade, while the relationship between genetics and the political arena-with terms such as rights, distribution, experti
Drawing on the literature on active objects and combining it with an ethnographic study of engineering work, this paper offers an alternative and complementary understanding of the problem of control in knowledge-intensive work. This problem concerns largely the question of how creative processes of knowing are enabled on behalf of the organization. The dominant response to this question revolves
Background. Well-specified and unambiguous treatment protocols are essential both for current practice and for the future development of radiation therapy. In order to provide assistance for writing good protocols, irrespective of treatment intention and complexity, up-to-date guidelines are highly desirable. Methods. We have analysed the radiotherapy work-flow, including clinical and physical asp
A full understanding of the properties of substellar objects is one of the major challenges facing astrophysics. Since their discovery in 1995, hundreds of brown dwarfs and extrasolar planets have been discovered. While these discoveries have enabled important comparisons with theory, observational progress has been much more rapid than the theoretical understanding of cool atmospheres. The reliab
Quinoa stalk (Chenopodium quinoa Willd.) from agricultural crop residue, totora (Schoenoplectus tatora) and o-macrophytes (aquatic flora) from Lake Titicaca (on the Bolivian Altiplano) were studied in a wet anaerobic co-digestion process together with manure front llama, cow and sheep. Anaerobic semi-continuous experiments were performed in (10) 2-1 reactors at a temperature of 25 degrees C with 3
In seeking to advance the understanding of the production, diffusion and negotiation of meaning in and between organisations, we introduce below the notion of mise-en-sens. Mise-en-sens refers to the performing art term of mise-en-sce` ne and builds on the French term sens denoting meaning as well as direction. Starting from a qualitative analysis of how Swedish wind farm developers manage the per
In the area of environment adaptations for people with physical disabilities, it is of vital importance that the design is optimized considering the human-environment interactions. All involved persons in such a planning process must be given sufficient support in understanding the information, so that everyone can participate actively. There is an apparent risk that discussions will be kept betwe
We propose a rational fabrication method for nanoimprinting moulds by scanning probe lithography. By wet chemical etching, different kinds of moulds are realized on Si( 110) and Si( 100) surfaces according to the Si crystalline orientation. The structures have line widths of about 200 nm with a high aspect ratio. By reactive ion etching, moulds with patterns free from the limitation of Si crystall
Bridge splitting in chloroform of the orthometalated chloro-bridged complex [Pt(mu-Cl)(2-Me2NCH2C6H4)](2) (1), with ethene, cyclooctene, allyl alcohol and phosphine according to 1 + 2L --> 2 [PtCl(2-Me2NCH2C6H4)(L)], where L = C2H4 (3a), C8H14, (3b), CH2CHCH2OH (3c), and PPh3 (4a and 4b) gives monomeric species with L coordinated trans or cis to aryl. With olefins the thermodynamically stable isom
The Tyranny of Small Steps (TYST) behaviour has been investigated. Explained through a systemic perspective, the behaviour TYST is an unwanted change to a system through a series of small activities that may be independent from one another. These activities are small enough not to be detected by the 'surveillance' within the system, but significant enough to encroach upon the 'tolerance zone' of t
The fractional dispersion model for natural rivers, extended by including a first order reaction term, contains four parameters. In order to estimate these parameters a fractional Laplace transform-based method is developed in this paper. Based on 76 dye test data measured in natural streams, the new parameter estimation method shows that the fractional dispersion operator parameter F is the contr
This study deals with changes in the plant cover and its net carbon sequestration over 30 years on a subarctic Sphagnum-mire with permafrost near Abisko, northernmost Sweden, in relation to climatic variations during the same period. Aerial colour infrared images from 1970 and 2000 were compared to reveal changes in surface structure and vegetation over the whole mire, while the plant populations
This paper describes a solution to the application of rapid detection of bicycles in low resolution video. In particular, the application addressed is from video recorded in a live environment. The future aim from the results in this paper is to investigate a full year of video data. Hence, processing speed is of great concern. The proposed solution involves the use of an object detector and a sea
In this study, a new strategy for fault detection and isolation is presented. This strategy is based on the design of a Lüneburg observer which is implemented via pole placement using linear matrix inequalities. Two residuals are formulated based on the state estimation error in order to be utilized in detecting and isolating faults happened on the system. Fault detection problem solves by change
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
