Den digitala strategin : En rapport om arbetet med en digital strategi för ett litet, nystartat företag
Social media, such as Facebook, Instagram and Twitter, have become popular platforms for social communication, and, increasingly, also important channels for business marketing. For a business intending to use social media for marketing, however, developing a strategy and building a trademark can be a challenge. This report describes how a small, newly established business enterprise can develop a digital strategy with clear goals and practical guidelines. The report describes a digital strategy for Gelato Scarfó and shows how this strategy is made concrete through a set of guidelines. The guidelines develop a trademark for identification and loyalty, and give advice on how new materials can be made consistent with the trademark..

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
Äldre och den nya världen : En kvalitativ innehållsanalys av medieanvändande hos den äldre generationen
AbstractTitle: The old generation and the New World - A qualitative content analysis of media usage of the older generationKeywords:Digital natives, digital immigrants, diffusion of innovation, content analysisThis study has its focus on how the older generation looks at today's media society and the use of today's media. Through a method of qualitative content analysis based on questionnaires, the aim is to examine what the older generation thinks about today's media, how they use them, and whether there are differences in groups according to age and previous work.The study selected theories bases on Marc Prenskys idea of ??digital natives, digital immigrants and Everett M Rogers book on "Diffusion of Innovation". These theories take up the difference on digital natives and digital immigrants and the spread of new technological ideas takes place through communication over different channels in time among causes people in a social system.The result of the study shows that many older people are good at making use of today's media, but also that many may feel alienation of today's media society. Development has proceeded rapidly in recent years and for the older generation it's sometimes hard to keep up.The conclusion of the study is that the older generation may need more help to discover how today's media can facilitate everyday life and enrich it with more communication despite the fact that it takes place through a screen..
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Pre-internationalisering : En fallstudie om beslutsfattare i små och medelstora företag och drivkrafterna mot en internationalisering
AbstractThis study is about describing the pre- internationalization phase and to studycompanies that are in this phase. We are trying to capture characteristics of decisionmakersin the pre- internationalization phase, to then compare the theoretical materialwith empirical material from case companies. Then in the final stages of the thesis, wewant to account for if we managed to answer our research questions. In the method, wegive a description of the approach selected in conjunction with the study. The study isqualitative and we used both primary and secondary data, with a deductive approach.The theory chapter will consider the most relevant theories that are related to the topic,which is internationalization, pre-internationalization, international entrepreneurship,and the psychology behind personalities, attitudes, and how these can affect theorganization's strategic decisions.
Gummitryck eller Photoshop : Kan gummitryck motiveras om det går att få samma resultat digitalt?
The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.
Passage Retrieval en studie av index
The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.
Digitala verktyg - Hjälp eller stjälp: Fyra lärares tankar om digitala verktyg i musikundervisningen i åk 6-9
This study shows the thoughts, hopes and wishes of two male and two female music teachers, in grades 6 ? 9 from four different cities of Sweden. The emphasis lays on usage of digital tools. As the schools now stand before lots of changes in its curriculums; the use of digital tools was the main thing that caught my interest. How has the schools interpreted what this means? What does this mean in terms of purchases for the schools? We already know that many schools are lacking proper facilities to conduct music lessons so this ads on even larger needs.

Studie av konstruktion och implementering av CORDIC-algoritmer
Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..
Scandinavium : Sveriges största inomhusarena
Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot. Nowadays most of the architectspresent all their works digitally and not with hand drawn material, as they didbefore the pc boom.Digital visualisation technique pushes the limits, when it is about presentingarchitecture projects virtual reality.This report studies how digital visualization technique is used among thearchitects today.Together with architects from ABAKO architect firm in Gothenburg, Sweden,interviews has been made to give answers about what they think about digitalvisualization technique. What are the opportunities, advantages- anddisadvantage with this digital technique?The answers from the architects, together with work that has been done withdigital visualization technique in a project called Project Sofiedal, shows thatthis technique has big opportunities when it comes to create nice looking VRpresentations. The result in this report also shows that this digital technique ismore time demanding compared to hand drawn presentations.The investigation shows that digital visualization technique is a goodcompliment when it is about showing the citizens how future projects willaffect the surrounding.

Total hälseneruptur: Resultat efter operativ respektive konservativ behandling.
ABSTRACTBackground: On behalf of the Orthopedic clinic, Västerås, a study has been conducted with focus on comparing the results after conservative and surgical treatment due to complete achillestendon rupture.Aim: To compare results when testing the active and passive range of motion, calf muscle endurance, estimation of pain related to the achillestendon and self-efficacy to be physically active for individuals who have undergone conservative or surgical treatment after complete achillestendon rupture.Method: 14 individuals afflicted by complete achillestendon rupture in 2010 were recruited as a purposive sample. Examination were conducted of: Ankle range of motion with a goniometer, calf muscle endurance through a toe-raise test, estimation of pain intensity related to the achillestendon by VAS and self-efficacy to be physically active through ?Exercise self-efficacy scale?. P-value and the median were calculated.Result: The results of ankle range of motion and calf muscle endurance were based on the difference between the injured and the healthy side. When testing active plantarflexion the conservative group had a median of 4 ? and the surgical group had a median of 10 ?.
Relationen mellan utformningen av digitala bibliotek och användarnas behov. En intervjustudie vid Göteborgs universitets digitala bibliotek.
The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.
