Ledarskapsutbildning ? till nytta eller nöje för Kommunstyrelsens ordförande? : En uppsats om betydelsen av ledarskapsutbildning

Many IT projects that have been developed in recent years are often considered to be unsuccessful. According to a study by Exido up to the 72% of all IT projects are considered to be failed. A failed IT projects means that the organizations that have ordered the new system may have higher costs or/and the system will not be ready in time. If costs are too high the new system might not be installed in the organization or if the system is not completed within the specified time frame the organization can become stagnant.In this paper we conduct an investigation of the failure of IT projects there we will examine where, in the systems development lifecycle four different phases, projects fail. We will conduct an empirical study of each phase, where we describe the key steps in the process; we will also investigate failed IT projects that are linked to the current phase.

Versaler, gemener & siffror: ett arbete om att skapa nya bokstavsformer i ett typsnitt

Vi befinner oss i en tid där behovet att kommunicera ständigt ökar och det gäller att hitta nya sätt att visuellt kommunicera. Vi ville därför undersöka om det är möjligt att på tre månader skapa nya bokstavsformer från grunden. Resultatet är 68 bokstäver och siffror vars uttryck och egenskaper presenteras och jämförs. Ni kommer att få en inblick i processen för detta komplexa och detaljrika hantverksyrke. Vi kommer avslutningsvis ge tips på vad ni ska tänka på vid framtagning av nya bokstavsformer..

Ett kommunikationssystem för fiberoptisk överföring av bilddata förvärvad av en miniatyriserad undervattensfarkost

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Implementering av ERP-system i offentlig sektor : Kritiska faktorer och mått att beakta för framgång

ERP-system (Enterprise Resource Planning Systems) spelar en allt större roll för organisationer och att implementeringen av dem blir framgångsrika är av stor betydelse för ett företag. Det finns exempel där en misslyckad implementeringsprocess medfört att hela företag försatts i konkurs.Följaktligen har flera studier gjorts gällande ERP-implementeringar. Ibland syftar artiklarna till att visa på rekommenderade tillvägagångssätt genom att redogöra för implementeringens kritiska framgångsfaktorer ? de moment, aktiviteter eller liknande som genom studien identifierats som avgörande för en framgångsrik implementering. Majoriteten av studierna har berört organisationer i privat sektor.Författarna till denna uppsats ansåg att det fanns starka argument för att dessa studiers resultat inte med nödvändighet är applicerbara på organisationer i offentlig sektor, utan att de kritiska framgångsfaktorerna kan skilja sig åt eller ha olika prioriteringsgrad i respektive sektor.

CMS och UX : tekniker för hur man utformar en god användarupplevelse

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

LEED i Sverige och i byggprojektet Borgarfjord 3.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Problem och hinder vid införande av CRM-system

I en global värld där närmaste konkurrenten bara är ett musklick bort från den potentiella kunden är behovet av att kunna marknadsföra på ett bra sätt elementärt.Försäljaren vill behålla befintliga kunder inom företaget och behovet av att göra sighörd har ökat betydligt. Detta har bidragit till att en ny marknad vuxit fram med stöd från informationssystem med funktioner som tillhandahåller möjligheten att rikta sin marknadsföring mot en speciell kund. Systemen kallas CRM-system, CRM står för Customer Relationship Management. Många större organisationer känner behovet av att införa denna typ avsystem i den egna organisationen. Kompetensen och insikten om vilka förändringar ett CRM-system innebär för organisationen är ofta mycket låg och införandet resulterar ofta i utebliven framgång.

Utveckling av ett centraliserat informationssystem

CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.

Delegering av arbetsmiljöuppgifter : - En studie av arbetsmiljöuppgiftsfördelningen på Metso Paper Karlstad AB mot bakgrund av gällande rätt

Delegation of assignments regarding the work environment is a complex topic that is difficult to illustrate. It is not explicit mentioned in the law and the established practice are ambiguous and vague. This has caused a lot of confusion, not only for private companies but also for executives within public administration.Metso paper Karlstad Inc. gave us the assignments to investigate their delegation system and to analyze the need of change before a planed readjustment. The purpose of this essay is therefore to investigate how the proposed delegation system is constructed and whether it fulfills the demands established by Swedish law.

En jämförelse av Sveriges och Storbritanniens producentansvar för förpackningar :

The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries. In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits. The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.

Underutnyttjande av vårdens informationssystem : Informationslogistik och samordnad vårdplanering

Förväntad effekt av vårdens elektroniska IT-system är ökad patientsäkerhet, vårdkvalitet och tillgänglighet. Ett första villkor för att kunna uppnå detta är att IT-systemet används. I denna studie granskas ett underutnyttjat IT-system, använt för informationsöverföring mellan olika huvudmän vid samordnad vård- och omsorgsplanering.Granskningen baseras på teorier om hur individers intention och vilja till att använda ett IT-system initieras eller upprätthålls genom omgivningens påverkan.Resultatet visar att IT-användare i den patientnära vården (mikrosystemet) saknar adekvat tekniskt, organisatoriskt (mesosystemet) och ledningsstöd (makrosystemet), vilket kan förklara underutnyttjandet..
