Kompetensf?rs?rjning under digital transformation En kvalitativ studie om hur sm? och medelstora managementkonsultbolag i Sverige arbetar med kompetensf?rs?rjning
The aim of this thesis is to analyze how small and medium-sized management consulting firms in Sweden work with human resource management during digital transformation. By interviewing companies, this study explores their approach to attracting, recruiting, and developing competence. The results showed that management consulting firms have good access to candidates, made possible by having a strong corporate culture and attractive working conditions - Crucial parts for attracting talent. Social media and networking are frequently used for marketing and attracting interesting candidates. Digital tools and social media showed to be useful during the recruitment process, but personal contacts and networking still play a central role.
Chatt - ett nytt sätt att kommunicera med bibliotekarien
This thesis presents a new way of providing library users with reference services, namely chat (text based digital reference service in real time). Our research questions focus on the role of reference service, a comparison of chat reference to other reference forms, and the interest for real-time, digital reference. Our literature review covered the areas of digital reference and reference theory, the results of which showed that an ongoing debate hardly exists among Swedish librarians on the topic of reference work. We interviewed librarians from the three different Swedish chat reference projects existing at the time of our study. Most interviewees were very positive about chat reference.
Kunskapssyn och behov av IKT-verktyg
In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Grafisk utvecklingsplattform för signalbehandling - Design och implementation
We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Optimerad bildsökning ? Bör vissa egenskaper prioriteras vid sökning efter en viss kategori av bilder?
As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..
Digitala servicescapes : En undersökning om samspelet mellan dramaturgi, storytelling, och servicescapes i en digital miljö
Denna undersökning utgår ifrån Mary Jo Bitners servicescape-modell om hur fysiska miljöegenskaper formade efter en berättelse eller tema påverkar serviceverksamheter. För att sedan implementera modellen i en digital miljö. Resultatet av att nyttja teorierna kring servicescapes på exempelvis serviceverksamheter ger besökare möjlighet att fly undan vardagen, medvetet eller omedvetet, genom en kombination av olika sinnen. I undersökningen såg vi att besökarens självmedvetenhet kunde jämföras med Mihaly Csikszentmihalyis teorier om ?flöde?, där medvetandetillståndet hos en individ blir uppslukat av individens aktivitet.
Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata
Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.
Information och interaktion. En studie av högstadieelevers informationssökning och informationsanvändning.
The aim of this master thesis is to examine information seeking andinformation use among high school pupils in two Norwegian highschools. The main research question focuses on different kinds ofinteraction or lack of interaction in the pupils? information seeking andinformation use.The theoretical framework of the thesis is based on a socioculturalperspective which allows for a specific focus of various forms ofinteraction. I investigate interaction in relation to concepts such associal practices, previous experiences and meaning making. Theempirical material consists of data from a large scale questionnaire (n=217) and in-depth interviews with six pupils.The results show that these pupils are used to interact with digital tools.The pupils trust printed sources more than digital ones, but at the sametime they prefer digital sources since these are easier to handle, it isquicker to locate information and this is easier to understand.
Modulgenerator för generering av Brent Kung-adderare
För att snabba upp addering av tal, vilket är en vital del inom signalbehandling finns olika algoritmer. En sådan algoritm är Brent Kungs vilken har en tidsfördröjning proportionell mot log2(N). I rapporten jämförs några olika varianter av adderare med avseende på grinddjup, vilket är proportionelltmot propageringstiden. En modulgenerator för Brent Kung-adderare implementeras med Skill-kod i Cadence. Modulgeneratorn kan genera adderare av obegränsad ordlängd och är även teknologi oberoende.
Digital kompetens : Om elevers ordbehandlingsfärdigheter i grundskolan
Syftet med denna undersökning var att undersöka den digitala kompetensen hos en grupp elever i årskurs nio på en skola i Stockholmsområdet. Utöver detta undersöktes några utvalda variabler för att avgöra deras eventuella inverkan på den digitala kompetens eleven tillägnat sig. Begreppet digital kompetens utnyttjas bland andra av EU-parlamentet och organisationen OECD vilka publicerat varsin skrift rörande nyckelkompetenser för livslångt lärande. Dessa två ger, tillsammans med en norsk undersökningsgrupps publikation, en gemensam definition av begreppet digital kompetens. Denna undersökning fokuserade dock enbart på ordbehandling, ett område inom den digitala kompetensen.Den empiriska undersökningen genomfördes med hjälp av en provliknande enkät där eleverna fick besvara frågor rörande ordbehandling.
DIGITALA RUM OCH RUMSLIGA DIGITALISERINGAR - hur hemmet tar plats p? Instagram
In a world obsessed with the visual our homes have gone viral. Through the frame of Instagram family members seems switched to furnitures and the so-called smartphone surely opened the door to new, digital places. Social media has become part of the life of many and, as an effect, also of the way we do our homes. In the era of digitalization, the concept of sharing has gotten some new dimensions where the borders of private and public, here and there, becomes blurred. Why do people post pictures of their homes on Instagram? How is it performed and what boundaries are pushed in the process? These have been some of the main topics guiding this thesis.
Det moderna biblioteket inätverkssamhället : En studie över kulturpolitikers och bibliotekariers åsikter om bibliotekens användande av sociala medier
?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts. This is analyzed from Castells theories about the network society and the digital divide.In summary, the study concluded that the majority of the culture politicians and librarians believe that social media is a part of the future of the library.
