Climate mitigation scenarios of drained peat soils

Abstract in UndeterminedThe national inventory reports (NIR) submitted to the UNFCCC show Sweden – which as many other countries has wetlands where parts have been drained for agriculture and forestry purposes, – to annually emit 12 million tonnes carbon dioxide equivalents, which is more GHG’es than industrial energy use release in Sweden. Similar conditions can be found in other northern countri

Dynamic Modelling of Emulsification in High-Pressure Homogenizers

Popular Abstract in Swedish Ett glas mjölk innehåller ungefär tusen miljarder små oljedroppar. Varje droppe är en tusendels millimeter stor. Dropparna är suspenderade i en blandning av vatten, proteiner och lösta molekyler. Små droppar av olja i vatten brukar kallas emulsioner. Emulsioner är vanliga beståndsdelar i livsmedel och finns exempelvis i allehanda mjölkprodukter, såser, smeter och dressiDifferent approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended paper

Optimal solution for the fixed margin problem in digital subscriber lines

Digital Subscriber Lines (DSL) are today one of the most important means for delivering high-speed data transmission. Dynamic Spectrum Management (DSM) is an emerging technique for dealing with crosstalk, one of the technology's most harmful problems. DSM judiciously designs users' power spectral densities so that the overall system performance is improved. This works aims at presenting a new insi

Sporadic Control of Scalar Systems with Delay, Jitter and Measurement Noise

Event-triggered control is a promising alternative to time-triggered control, especially for severely resource-constrained networked embedded systems. Previous work has shown that event-triggered control can reduce both the output variance and the average control rate in scalar linear stochastic systems compared to time-triggered control. It has also been shown how a minimum inter-control interval

“And we found that niche, the bank and I…”

Abstract This paper addresses the importance of networks for entrepreneurs in bankruptcy, based on interviews with entrepreneurs who have experienced at least one bankruptcy. Analysis of the interviews reveals two discursive themes: entrepreneurship and bankruptcy. Entrepreneurship is expressed in terms of initiative and of contacts in business contexts; bankruptcy concerns economic marginalizatio

Building shielding loss measurements and modelling at the 5 GHz band in office building areas

This paper presents narrowband path loss measurements carried out at the 5.1 GHz band. The focus has been on building-shielding loss in office-building areas. Both azimuth and elevation dependence have been studied. The measurement campaign was performed in a multi-storey building on three different floors in an indoor office environment. A helicopter was used to simulate a mobile satellite system

Current issues in pictorial semiotics. Lecture two: The Psychology and Archaeology of Semiosis.

In this lecture, we will discuss the emergence of the semiotic function, both ontogenetically and phylogenetically, and we will consider the part played by the picture sign in this development. In order to demonstrate that pictures are indeed signs, we will explore the basic elements of the sign presupposed but never put into focus neither by Saussure nor by Peirce. Indeed, explorations in the psy

Medical Applications of Laser Spectroscopy

Lasers are finding many applications in medicine and biology. While most laser use focuses on the heat generation of the laser beam interacting with tissue, spectroscopic aspects play a more dominating part in a number of emerging applications. Tumour-seeking agents, such as hematoporphyrin derivative (HPD), in combination with laser radiation provide new possibilities for cancer tumour detection
