Radio frequency identi cation (RFID) is a rapidly emerging technology that enables au- tomatic remote identi cation of objects. Passive and semi-passive RFID systems can be distinguished from other forms of wireless systems, because the RFID tags (transponders) communicate by way of backscatter. In addition, passive tags derive their energy from the RF energy emitted by the reader. RFID technology can provide a fully automated data capture and analysis system. Compared to a passive RFID system, an open platform semi-passive UHF RFID tag can provide identi cation, security, low-power (compared to a wireless sensor net- work(WSN)), medium range and medium processing speed. However, the eld of semi- passive RFID is still under development, and has yet there are no open development platforms available. This thesis develops a prototype of a semi-passive UHF RFID tag that is compatible with the leading UHF RFID standard EPCglobal Gen 2 Class 1. I alsot has the exible I2C and analog digital converter(ADC) interface, which allows the additional of external analog and digital sensors. The sensor data can be read by microcontroller and stored at memory. Standard reader can get sensor data by sending QUERY and READ command to tag. Test results of our open platform semi-passive UHF RFID tag demonstrated that it can achieve a read rate above 50% when an open platform semi-passive UHF RFID tag is placed four meters from the reader antenna and the reader output power is set to 21 dBm. In addition, the proposed semi-passive open platform RFID tag consumes very little power (4.9 mA in 2V with system frequency set to 8MHz).

Die Technische Universität Chemnitz setzt seit vielen Jahren auf den Einsatz von Open-Source-Software im gesamten Campus. Da liegt es nahe, dass auch die Universitätsbibliothek Chemnitz auf frei verfügbaren Code zurückgreift. Die Möglichkeiten für Bibliotheken, Anwendungen und Dienstleistungen auf Open Source zu stützen, haben sich in den letzten Jahren deutlich verbessert, da zahlreiche spezielle Softwarelösungen für Bibliotheken entwickelt wurden. Neben dem Katalog auf VuFind-Basis, dem ERMSystem Coral und weiteren im internen Bereich eingesetzten Speziallösungen wird seit April 2013 auch eine interaktive Standortkarte auf Grundlage von Open-Source-Code in der Universitätsbibliothek Chemnitz eingesetzt.

Open source software is becoming a credible and realistic alternative to proprietary software in municipalities. The aim of this thesis is to explore the strategies and logical issues that inspire and motivate municipalities to migrate into or integrate use of open source software. The research approach used in the study is an explorative, comparative case study performed in the three Swedish municipalities of Falköping, Alingsås and Kungälv, which considers implementation and use of OpenOffice in administration. The methodologies used in the case study were in-depth interviews with Chief Information Officers in the municipalities and document analysis. The interviews were combined with the tool of SWOTanalysis to further focus on the reasons for choosing OpenOffice as an application program. There is certainly not a unique strategy to migrate into or integrate use of Free/Open Source Software. Since each municipality is autonomous in the process of decision-making, various strategic planning or guidelines are use in different municipalities. In the municipalities of Alingsås and Kungälv the strategic planning is used for leading the processes of implementation of new software applications. However, in Falköping municipality, the procedures are guided by a set of guidelines. The lower Total Cost of Ownership and the Free/Open Source Software’s freedoms besides many other advantages, make the municipalities stimulated to migrate into use of OpenOffice suite. In contrast, there are some drawbacks and barriers, such as shortage of internal and external standardization and lack of user knowledge and familiarity, which demotivate the municipalities to take this decision. To lower costs of IT administration seems to be the most significant factor in motivating municipalities to migrate into use of OpenOffice. More research is needed in order to find out the consequences of implementation of OpenOffice in municipalities as well as to investigate if Total Cost of Ownership really is decreased by the use of Open Office.

Living Lab är en öppen innovationsmiljö där innovationer samproduceras, testas och verifieras av användarna, tillsammans med företag och akademin i en kontext som representerar innovationens tänkta användningsområde. Genom samverkan kan olika värden skapas för företagen. Syftet med uppsatsen var att undersöka hur Living Lab skapar värde för företag och vilka värden företag kan identifiera ur de användarcentrerade aktiviteterna. Uppsatsen karaktäriseras av en kvalitativ ansats och grundar sig i en explorativ undersökning med djupintervjuer där fyra företag ligger till grund för uppsatsens resultat. Uppsatsen har visat att Living Lab skapat värden för företag genom att de fått mer tilltalande produkter, identifierat nya användarkategorier och samordnat resurser med företag. Living Lab är därmed värdeskapande för företag genom stöd för utvärdering, ny- och vidareutveckling av innovationer. Samverkan mellan användare, företag och akademin öppnar upp för ett kunskapsutbyte vilket skapar värde för företag då kompetensutveckling äger rum och en djupare kunskap om användarna kan erhållas

Denna rapport visar hur ett företag kan gå tillväga för att sammanställa utvecklingen av proprietär tillägg till öppen källkod. Rapporten presenterar en strategi för hantering av extern källkod. Examensarbetet har utförts på Ericsson AB i Linköping och har gått ut på att sammanställa deras internutveckling av protokollavkodare till Wireshark. I rapporten presenteras hur ett program som licensierats under öppen källkod kan utvärderas. Vidare ges en kort introduktion till de legala grunderna för öppen källkod. Rapporten tar även upp de risker som kan associeras med öppen källkod. Examensarbetet resulterade praktiskt i ett system som sammanställde Ericssons internutveckling av proprietär tillägg till öppen källkod.

Open innovation has been widely debated in management literature. However, little attention has been given to how small and medium sized enterprises manage to open up their innovation process. Consequently, various questions remain unanswered. In particular, we want to shed light on the following issue: how small and medium-sized enterprises manage organizational changes in their journey from closed to open innovation. A literature review examines how small and medium-sized enterprises open up their innovation process based on nine perspectives. Then, the reference framework addresses the organizational changes embedded in evolving from closed to open innovation. In this sense, we use acknowledged concepts on organizational change research to carry out an in depth-case study on a small and medium-sized enterprise evolving in the sports equipment industry. The results demonstrate that, in its journey from closed to open innovation, the small and medium-sized enterprise has had to stimulate and to manage changes to four company’s dimensions i.e. corporate culture, networking, organizational structure, and knowledge management systems. The paper concludes by highlighting the diverse organizational changes undertaken by the company on these four dimensions. Based on this paper’s conclusion, managerial implications and discussion for future research are drawn.

Using design patterns is a widely accepted method to improve software development. There are many benefits of the application of patterns claimed in the literature. The most cited claim is that design patterns can provide a common design vocabulary and therefore improve greatly communication between software designers. Most of the claims are supported by experiences reports of practitioners, but there is a lack of quantitative research concerning the actual application of design patterns and about the realization of the claimed benefits. In this paper we analyze the development process of over 1000 open source software projects using version control information. We explore this information to gain an insight into the differences of software development with and without design patters.
