Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

This essay concerns dance as an exhibition object by examining the permanent exhibition at The Museum of Dance in Stockholm, Dansmuseet. Due to its dependence on the temporality and movement of the lived body, dance does not easily lend itself to being exhibited in a traditional exhibition display; and since the live dance performance itself is ostensibly absent at the exhibition display, other means of representation must be relied upon in order to evoke the exhibition visitors? experiences of time and movement as well as the feeling of dance. Starting from a phenomenological first-person perspective, as an exhibition visitor, I present three ways in which such experiences may come about. The cross-section of the experience evoked and the means that trigger them are intermedial, spatial, and performative taking their departure in the visitor?s pre-understanding of dance..

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

This paper deals with an object donated by a group of members of the public to the Royal Armoury in Stockholm, Sweden. The donators claimed to own a horse bit that had been used by King Gustav II Adolf's mount in the battle of Lützen, where the King was killed. The bit was a gift to the donators' ancestor, the farmer and politician Petter Jönsson, from the King of Sweden, Oscar I, in the 1850's. In this paper, the donated bit is examined and found unlikely to be the bit used at Lützen. The examination also revealed that the bit now worn by the horse in its display is a prop, included in the group of objects in the 19th century, and that the original bit probably was lost in a fire in 1648.

The purpose is to explore and describe norms and values concerning emotions and emotional expression inSweden and Greece from an emotionsociological perspective. Do emotional regimes on a national level existand if they do, how do they differ? To answer this question qualitative interviews have been conducted withnine Greek/Swedes, men and women of different ages, who have lived in both countries and who speak bothlanguages. A quantitative survey study, employing a survey previously used in a Swedish study about emotions,has also been undertaken. Previous studies have shown that emotional regimes do differ historically and acrosscultures, but no study so far has focused on the differences between examples of North European and SouthEuropean cultures.The theoretical framework consists mainly of Hochschild´s theories about feeling/display rules and emotionwork, but the analysis also draws on Collin´s theory of interaction ritual chains and on Sociology of Emotionsmore broadly.The results suggest that different national regimes can be distinguished primarily in terms of display rules andin the skills of emotional alternations.

En ambient display är menad att fungera för användaren enbart genom att hen snabbt överblickar produkten. Denna form av display är perfekt att nyttja i dagligvaruhandeln där utbuden ständigt växer samtidigt som konsumenten snabbt vill hitta det den söker. I denna studie utforskas fördelarna med att använda färg och symbolkombinationer, som skapar en ambient display, istället för text när det kommer till att kategorisera i tidningssektionen. Feature- integrationsteorin beskriver hur den ambienta displayen ger stöd för användarens kognitiva processer, den är mer effektiv genom att den låter konsumenten använda det perifera seendet i sitt sökande.Tidningssektionen är en produkt användaren inte nyttjar frekvent och denna design fungerar genom att kunden redan ska veta hur den önskade kategorin är representerad, det är därför väldigt viktigt att inlärningen sker snabbt. I studien framkommer vikten av att skapa bra associationer mellan färg och kategori, vilket har en extremt signifikant påverkan på inlärningsförmågan hos användaren.Studien utvärderar även vilka färg- och kategorikombinationer som är lämpliga för Tidsam, distributör av tidningar.

Beacon AB has been producing Gobos for some time. A Gobo is a small round sheet used in projectors almost like a slide. It is used mostly in the commercial and entertainment business. Today these Gobos are created by using a film (also called mask). A digital exposure machine called LIOS has been developed to make it possible to create Gobos using direct exposure.

This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.

Kvinnor har sedan 1980 fått tjänstgöra som officer i Sveriges försvarsmakt. Trots detta är fortfarande de kvinnliga officerarna och soldaterna i klar minoritet i organisationen. FN:s säkerhetsråd har arbetat fram två resolutioner som båda strävar efter att involvera kvinnor i större omfattning när det gäller arbeten vid kris, krig och konflikter. Inte enbart att öka andelen kvinnor i hjälpande trupper, utan även involvera lokalbefolkningen. Hur ser då verkligheten ut vid de internationella insatserna? I detta arbete presenteras en fallstudie om MOT Juliette, ett kvinnligt observationsteam som under sju månader tjänstgjorde i Afghanistan.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

Background/Problem: Since the IT-burst in 2000 it has been recession within IT-consultant firms (Sif 2004). The tendency is, however, changing slightly and IT-consultants firms are getting more assignments again (Arbetsmarknadsstyrelsen ? AMS, 2004). IT-consultants firms are however still related to stressed per-sonnel (Handelskammaren 2004; Hallstedt 2001). Another critical factor is the communication between management and workers.

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

AimThe specific questions in the theoretic part were:What is contained in the terms "balance and balance skill" and how can this skill be measured?The specific questions in the empirical part were:How does balance skill in different age categories of children correlate with biological and physiological parameters such as age, gender, body height, weight and level of physical activity?MethodsLiterature search based on books and scientific papers related to the questions posed above. Selection was made at libraries and on?line through "Pubmed". Specific search words were used.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..
