Dynamisk simulering med hjälp av RPS-beräkningar för radiovågors utbredning i urban miljö

Militära insatser i urban miljö kommer troligen att öka alltmer. Detta kräver soldater till fots eftersom dessa lättare kan förflytta sig via och mellan byggnader. Varje deltagande soldat kommer att behöva egen radioutrustning. Då stadsmiljö är ett relativt outforskat område vad gäller militär radiokommunikation är det viktigt att öka förståelsen för radiovågors utbredning i stadsmiljö. Härtill har institutionen för Informationsöverföring på FOI köpt in programmet Radiowave Propagation Simulator (RPS).

Tillgänglighet och varsamhet i vardagens stadsmiljöer

This graduate thesis deals with the challenges facing us as we gradually make our urban environments withtheir many public buildings, such as shops, cafés and cinemas, more accessible for disabled people. Theperspective taken is that of the conservationist, who in her or his profession looks to the cultural andhistorical characteristics in buildings and building environments. In order to gain better accessibility, changesin the physical fabric need to be made, with consideration for the cultural and historical characteristics.The introduction presents the subject of considarate accessibility. The second chapter deals with the legalaspects concerning the protection of buildings as well as the accessibility for disabled people. Severalinterviews with different participants are presented here, aiming to tie the legislation to the reality of theconservationist, the disabled, the civil servant working with accessibility issues and the property owner,whose responsibility it is to make the adjustments necessary to improve accessibility.

Val av energisystem för en hållbar stadsdel : En fallstudie av Östra Sala backe

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

Utveckling av ett användbart IT-stöd : för att stödja operativa arbetsrutiner

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

Stråket - Utveckling av gång- och cykelförbindelse mellan Kungsmarken/Marieberg och Amiralen i Karlskrona

Det pågår en diskurs om att reducera bilismen och det blir därför allt viktigare att skapa hållbara gång- och cykelstråk. Detta eftersom bilismen påverkar staden negativt ur ett miljö- och trygghetsmässigt perspektiv. Då Karlskrona kommun avser att etablera ett nytt resecentrum med 450 närliggande bostäder i området Gullberna ökar behovet av ett väl fungerande gång- och cykelstråk för detta och omkringliggande områden. Det är därför av stor vikt att utveckla det gång- och cykelstråk som sträcker sig mellan bostadsområdena Kungsmarken och Marieberg via framtida Gullberna stationsområde och vidare mot halvexternt handelsområdet Amiralen för att tillgodose den nya befolkningsökningen i och med nybyggnation av bostäder och resecentrum..

Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden

Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.

Energiförbrukning för putsade, odränerade träregelväggar i fuktigt respektive torrt tillstånd

In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.

"Jag blir den du säger att jag är" : Intagnas upplevelser kring bemötande och maktutövning på kriminalvårdsanstalt.

Prisons are for many an unknown world, and few know about the prison culture which includes unwritten rules, power structures, interactions and relationships between inmates and correctional employees.While many think that Swedish prisons are too comfortable,inmates are facing extreme stress due to surveillance and detention, by depriving inmates their possibility to shape their own lives. When the inmates is deprived of control over their own life?s the penal system have great power to shape and to influence the inmates.The purpose of this paper is to investigate prisoners' experiences of treatment and exercise of power in prisons. Starting point is to examine what are the kinds of relationships between prison officers and inmates from a power perspective, if there is any difference between the closed and open prisons and how the inmates affected by the structures that exist.Based on my overall purpose, and with my informant´s stories which revealed a number of similar points, four main headings were developed; Mass media and society´s view, and unknown world, interaction between inmates and prison officers and consequences.Prison officers with the role as a contact persons as well and other staff which work close to the inmates play a significant role by supporting through motivational interviewing and can help the inmates to gain insight about their life situation and actions. My informant?s underlined that a good contact person can either help or discourage.Inmates who contributed with their experiences express that there is a big difference between open-and closed prisons.

Driving forces of land use : underlying factors in peri-urban land use

Swedish agriculture faces future challenges regarding food production and land use. Increased competition for agricultural land creates complex situations, where conflicts may arise when productive crop land is in demand not only for food production but also energy- and fodder production. On top of that there is an obvious conflict of goals between agricultural production and non-agricultural exploitation of agricultural land. In several emerging economic regions it is noticeable how agricultural land is being expropriated for development of urban settlement and infrastructure, carrying potentially significant long-term effects. During the last decade the exploitation of agricultural land in activities other than food production has increased in Sweden and is expected to continue in the same manor. Approximately 700 hectare of land in Sweden is diverted from food production, annually, and in 2013, the Uppsala Municipality showed the greatest change in land use of all municipalities (SCB, 2013).

Kalibrering av en transient GT-Power modell av en SI PFI turbo motor

I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.

Föräldraskap, kön och jämställdhet i Maria Svelands Bitterfittan

The aim of this Masters´ thesis is to examine parenthood, gender and equality. The analysis is based on the novel Bitterfittan. The primary theoretical points of departure are Judith Butler?s theory about doing gender and Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes. I use Lisbeth Bekkengen?s thesis in which the nuclear family is seen as an institution which is upheld by two structures; that is the social relationships man-woman and parent-child, and also by two discourses; on the one hand a notion that fathers and mothers are principally different and on the other hand the child focus.

Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
