En smartphone, lätt att personifiera

Take your phone out from your pocket and look at it. Chances are that a certain California-based company made it; in 2013, it was quite likely. If you flip it over and remove the shell you have added (or look through the protective film), you might also learn that it was assembled in China. Flip it over again and look at the picture of something or someone you find great affection for, protected by yet another thin film. While who made it and who assembled it might vary, and it does not matter from now on, the other parts about protective barriers and personalization might be more accurate.

Ute och cyklar? : på jakt efter en metod att mäta upplevelse

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

Modellering av sträckriktning med hjälp av FEM

Målet med detta examensarbete är att bedöma möjligheten för generell modellering av riktning av tunna stålband med hjälp av finita element metoden (FEM). Detta är ett delmoment inom ett EU-projekt rörande bandformskontroll i kallvalsning och kontinuerliga glödgningslinjen. I detta arbete har fokus legat på att skapa en modell som löses med FEM för ett befintligt riktverk på Outokumpu Stainless i Långshyttan för att se om möjligheten för allmän modellerering av riktning med hjälp av FEM är möjlig. Valsningsförsök på ett stålband har gjorts på LuCoil i Luleå där planhetsfel medvetet har valsats fram och uppmätts. Detta stålband har sedan riktats vid försök på Outokumpu Stainless i Långshyttan och data från riktningen har samlats in.

Konstruktion av instrument för dragprov på nervceller

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

Modellbaserad drivlinereglering

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

En undersökning om fallolyckor med gångtrafikanter

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

Smarta elnät i Sverige : Energibranschens förutsättningar och förväntningar

The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.

Vem bedömer de äldres rätt till särskilt boende? : En kvalitativ innehållsanalys

Uppsatsen syftar till att redogöra för den subjektiva upplevelsen av att bli bedragen i en nära relation och är således en fenomenologisk ansats. Undersökningen har baserats på tre kvalitativa intervjuer, där de intervjuade redogjort för sin subjektiva upplevelse av att bli bedragen samt definierat begreppet otrohet. Vi har utgått från teorier om skam, skuld och stigma för att kartlägga hur upplevelsen påverkat självet. Scheffs teorier om sociala band har använts för att beskriva påverkan på individens förhållanden till andra. Vi har upptäckt att en monogam relation inte är ett krav för att otrohet ska uppfattas.

Betongbjälklag med limmad matta : olika behandlingars effekt på alkalitet, fukthalt och emissionsbildning

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Erfarenheter av utedrift med köttdjur i Sverige och Kanada :

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

Jakten på idémetoder : Bland böcker, bloggar och bröderna Härén

SyfteSyftet är att belysa och lyfta fram olika metoder som hjälper människor att bli skickligare på att ta fram nya idéer.FrågeställningMåste vi vänta på att äpplet ska falla ner i huvudet på oss för att vi ska få bra idéer, eller finns det några metoder som kan hjälpa oss att ta fram idéer på löpande band? Dessa två frågor är drivkraften i vår jakt genom böcker, bloggar och bröderna Härén. Böckerna beskriver kreativitet och hur människor kan göra för att bli mer kreativ. Men hur tillämpar bloggare kreativitet i verkligheten? Vad säger Fredrik och Teo Härén angående kreativitet och idémetoder?ResultatKreativitet uppkommer genom att göra saker på nya sätt eller att vi gör nya saker vi inte prövat på förut.

En socialpsykologisk studie om organisationsvisionens betydelse för sociala relationer i arbetsvardagen

In this study, we have considered the impact the organization`s implementation of its vision of the psychosocial work enviroment has been for the relations between the employees. We have primarily relied on a hermeneutic approach to understand our empirical data, and when we have interpreted and made a socialpsycological analysis on our collected empirical data. We have used Smith´s Institutional Ethnography, Sheff`s Social bonds and Asplund`s theory of Social responsivity. To collect the empirical data we have combined quantitative and qualtitative methods and a textanalysis at a visiondocument in the aim of capture both the depht and the breadth of our chosen fields of study. The results we have found shows that the psycosocial work environment within the organization can be seen as interplay between individual and enviroment and between individuals as well and that this interaction is influenced by the organizational culture that is created by the organization`s political vision.

Design av utomhusträdgård i Dubai :

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.
