The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

To work in an unpredictable work environment requires communication that functions well. In every organization it?s important that employees receive information that is relevant yet not confusing. Due to that, our ambition with this study is to understand how rescue effort organizations communicate in meetings; and whether their communication is clear or not. Our subject for this case study is the Emergency Services in the region of Karlstad.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Denna underso?kande designstudie utforskar hur visuellt material till en simulator kan komma att se ut och hur va?gen fram till det fa?rdiga designen kan se ut. Simulatorn som sta?r i centrum fo?r just denna studie kallas fo?r Simulerade Provokationer (SimProv) och har la?rarstudenter som huvudsaklig ma?lgrupp. I SimProv kan la?rarstudenten som anva?ndare va?lja mellan fyra olika handlingar i en klassrumssituation.

This report contains a programming improvement work in a LabVIEW? fire testing furnace control system for SP Fire Technology in Borås. Here materials and products behaviour are tested and evaluated, being exposed to fire. For this task, UGNET is being used for control and surveillance of the testing furnace system. System hardware has been updated gradually through the years, while the software has been neglected.

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

Vid dimensionering av lokal brand enligt bilaga C, i EN 1991-1-2, så erfordras en värmeutveckling som beräknas i bilaga E. Boverket hänvisar dock i Europeisk konstruktionsstandard, EKS, 9 att bilaga E inte får användas utan rekommenderar i stället att Boverkets allmänna råd om brandbelastning, BBRBE, bör användas. En problematik vid användandet av BBRBE, är att den inte innehåller några beräkningsmetoder för värmeutvecklingen. Det åvilar därför projektören att vid varje enskilt fall vid analytisk dimensionering använda sig av relevanta beräkningsmetoder för att beräkna effektutvecklingen vid lokal brand.Syftet med det här examensarbetet är därför att utreda och jämföra beräkningsmetoder i Eurokod för lokal brand i hyllställningar i livsmedelsbutiker med simuleringar i FDS, Fire Dynamics Simulator, för att komma fram till slutmålet som är att fastställa en metod för att ta fram brandeffektkurvor och temperatur-profiler vid dimensionering av lokal brand. En metod som baseras på ekvationer från bilaga C och bilaga E i EN 1991-1-2.

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
