- PostTransparent Photovoltaic Windows(2023) Kaminska, Kinga; Nilsson, Elin; Rehnberg, Isak; Chalmers tekniska högskola; Chalmers University of Technolog; Albinsson, Bo; Albinsson, BoThe rapid development of photovoltaics has inspired new innovative ways to capture the sun’s energy. One such measure, that has proven benefits but has remained a niche and whose future potential is relatively unknown, is transparent photovoltaics (TPV). Current research is mainly focused on integrating windows with TPV since it could lead to a significant increase of available area for photovoltaics, especially in dense cities. This project provides an overview of TPV windows utilizing CdTe thin films in order to assess the future potential of TPV windows, identify barriers that hinders the technology from diffusing and determine potential environmental impacts associated with production and utilization. The project concludes that TPV windows exhibits great potential regarding energy output in climates with high solar radiation. Development is rapid with different materials and techniques looking like viable options in the future. However, the short life-span and the challenge to maintain efficiency in larger windows hinders the technology’s diffusion. There are also signs of potential environmental impacts for CdTe TPV in the form of toxicity windows but further research is required to draw weighted conclusions.

- PostThe Open Source Licenses of Popular DBMSs(2023) Weckner, Christian; Chalmers tekniska högskola; Chalmers University of Technolog; John, Jobin; John, JobinDatabase Management Systems have been a critical part of digital infrastructure for decades. They are a necessary tool to efficiently work with large amounts of data. Through the years, as the way data is used has changed, so has the DBMSs. Today, there are hundreds to choose from, each with pros and cons, support for different data models. As they are just pieces of software, some are use commercial licenses, while others use Open Source licenses. On DB-Engines.com, there is a ranking of the most popular DBMSs, based on certain criteria. 18 of these were chosen, and had their licenses analyzed. Out of the 18, 12 were licensed as Open Source. Breaking the Open Source DBMSs down further, 8 used permissive licenses, 2 used copyleft licenses, and 2 used licenses which are actually disputed. The Open Source Initiative have criticized the two new licenses, called the Server Side Public License and the Elastic License. These were created as a response to the growth of the Software as a Service-industry, and claims to combat the theft Open Source software. The response to these licenses have been fairly negative, despite their claims of openness. How they will affect the DBMS landscape, and Open Source software in general, remains to be seen.
