Autoliv Electronics AB utvecklar, tillverkar och säljer produkter till fordonsindustrin. När en produkt utvecklas utförs en rad olika miljötålighetstester. Dessa miljötålighetstester skall simulera alla miljöfaktorer som produkten stöter på under sin livscykel. Miljöfaktorerna som testas är mekaniska, kemiska, elektriska och termiska.De mekaniska miljöfaktorerna innefattar vibrationer, stötar, fall och slag. När vibration och stöttest utförs används en vibrator.

The Secret Fashion Council blends spirituality with fashion, art and design. This jewellery collection shows the connections between parapsychology and quantum physics, based on the study of matter and energy, that everything in the universe is built of vibrations. Many believe psychics have the ability to sense this. By using the skills of a psychic, the Secret Fashion Council invites the wearer to have the jewellery ?read? and evaluated in a most special way, tracing the wearer?s spiritual past, present and future.

In order to detect movements and vibrations on different appliance, especially robots and self-going devices are used different sensors. One of the most used movement sensors are accelerometers. They are three different types of accelerometers one-axes, two-axes and three-axes. They can be analogue or digital. Husqvarna AB uses an accelerometer to detect movements of their self-going lawnmower Automower.

This study aims to explore managers? experiences and perceived conditions for exercising leadership in both hybrid and physical work environments. The empirical material consists of eleven semi-structured interviews and four policy documents. The sample includes eleven managers, of whom six work in a physical environment and five in a hybrid setting. The study follows an inductive approach, where the interviews were first collected and later analyzed by identifying patterns and connecting them to theories on different leadership styles, monitoring, and trust.

Denna studie unders?ker den upplevda tryggheten hos kvinnor vid Fr?lunda Torgs sp?rvagnsh?llplats i G?teborg och identifierar en rad olika faktorer i den fysiska milj?n som p?verkar deras upplevelse. Med en feministiskt geografisk infallsvinkel och teoretiska ramar som inkluderar Broken Window-teorin, CPTED syftar studien till att bidra till en ?kad f?rst?else f?r hur Fr?lunda Torgs sp?rvagnsh?llplats uppfattas och kan utformas fr?n kvinnornas perspektiv. Genom semistrukturerade intervjuer, analyserar studien kvinnors upplevelser av trygghet och otrygghet vid sp?rvagnsh?llplatsen Fr?lunda Torg.

The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.

Autonoma och fj?rrstyrda fartyg blir successivt vanligare inom sj?fart. Denna utveckling st?ller stora krav p? den funktionella s?kerheten hos styrsystem. S?rskilt viktigt ?r det att ?verg?ngarna mellan olika k?rstationer sker p? ett tillf?rlitligt s?tt f?r att undvika farliga systemtillst?nd.

Efter riksdagsvalet 2022 ingick Moderaterna, Kristdemokraterna, Liberalerna och Sverigedemokraterna ett politiskt samarbetsavtal, det s? kallade Tid?avtalet. Avtalet representerar en politisk kurs?ndring i svensk v?lf?rdspolitik, d?r fr?gor om kriminalitet, migration och effektivisering av v?lf?rden ges en central plats. Syftet med denna studie ?r att analysera hur socialt arbete och v?lf?rd representeras i Tid?avtalet och vilka implikationer dessa representationer har f?r socionomers professionella roll och social arbetares yrkesetik.

Many new surveillance technologies are being rapidly implemented in Sweden. Despite surveillance posing a potential threat to personal integrity, public support for surveillance in Sweden remains strong. However, little attention has been directed towards what causes these attitudes. One possible cause is that Swedish officials have unanimously shifted their framing of surveillance, from emphasising threats to personal integrity to instead emphasising its usefulness to maintain peace and security. According to framing theory, such communication can be used to legitimise policies and sway public opinion.

Husqvarna is a world leading producer of chainsaws with a well-established brand name. Husqvarna now has an interest in investigating the possibiltiy to expand their production of chains and guide bars to include cutting equipment for timber-harvesters.This project is a technical study which aims to answer questions about cutting equipment for timber-harvesters that have been decided in cooperation with Husqvarna. The questions have mainly been focused on forces, cutting speeds, service and maintenance -as well as general questions regarding the size of the Swedish market.Two methods have been applied to answer the questions. Interviews with retailers of harvesters, producers of harvester heads and harvester drivers.The main findings in this project show that there is a relatively small selection of harvester chains on the Swedish market. In contrast to the selection of harvester chains the selection of guide bars is quite large.

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.
