1. Radegård, Madeleine. Habitatanvändning av svartmes (Periparus ater) och entita (Poecile palustris).

Degree: Environmental and Life Sciences, 2017, Karlstad University

Competition is common between closely related species, no less between birds. For tits in temperate forests, competition for food and space is usually stronger during winter, as foraging opportunities are few. Many species with an otherwise broad diet, therefore,  start eating the same available food items and thus increase their overlap in the use of food resources. The purpose of this study was to investigate whether coal tits and marsh tits compete with each other. The observations were made in 10 selected locations with varying types of forests. In the study, 20 entrants and 20 blacks were observed for 5 minutes per individual. Every minute the position of the individual was noted in the tree.The results indicate an asymmetrical competition between the species because marsh tits changed its habitat use and were found lower in trees in the presence of coal tits, whereas coal tits did not change its habitat use in the presence of marsh tits. The movement by the Marsh tits can then reduce competition and give both species a better chance of living together.  

Konkurrens är vanligt mellan närbesläktade arter, inte minst mellan fåglar. Konkurrensen om mat och boplatser blir oftast starkare på vinterhalvåret då det är svårare att hitta mat och många arter som annars föredrar olika sorters föda då börjar äta samma sort. Syftet med denna studie var att undersöka om svartmes och entita konkurrerar med varandra. Observationerna gjordes på 10 utvalda platser med varierande skogstyper. I studien observerades 20 entitor och 20 svartmesar i 5 minuter per individ. Varje minut noterades individens position i trädet. Resultaten visar att det kan förekomma en asymmetrisk konkurrens mellan arterna då entitan flyttade sig nedåt i höjdnivå i närvaro av svartmes, medan svartmes inte ändrade plats i närvaro av entita. Entitans nedflyttning kan då minska konkurrensen och ge båda arter bättre möjlighet till samlevnad.

2. Hageskog, Mia. BikeLab : Ett cykeluthyrningssystem för en hållbar livsstil, miljö & ekonomi.

Degree: Design, 2015, Linnaeus University

Med intentioner att utveckla mer hållbara städer har man på många ställen världen över satsat på mer miljövänliga transportsystem och tjänster. Denna rapport kommer att ta upp ett förslag på system för en cykeluthyrningstjänst i Växjö, med fokus på studenters beteenden och rörelsemönster. Syftet med detta system är att gynna en miljömässig, ekonomisk och socialt hållbar tillväxt för Växjö stad.

With the intention to develop more sustainable cities, many places across the world have invested in more environmentally friendly transport systems and services. This report will showcase a proposal for a system, a bicycle rental service in Sweden, with focus on students behavior and movement patterns. The purpose of this system is to promote an environmental, economic and socially sustainable growth for the City of Växjö.

3. Leung, Philip. SecuRES: Secure Resource Sharing System : AN INVESTIGATION INTO USE OF PUBLIC LEDGER TECHNOLOGY TO CREATE DECENTRALIZED DIGITAL RESOURCE-SHARING SYSTEMS.

Degree: Information and Communication Technology (ICT), 2015, KTH

The project aims at solving the problem of non-repudiation, integrity and confidentiality of data when digitally exchanging sensitive resources between parties that need to be able to trust each other without the need for a trusted third party. This is done in the framework of answering to what extent digital resources can be shared securely in a decentralized public ledger-based system compared to trust-based alternatives. A background of existing resource sharing solutions is explored which shows an abundance third party trust-based systems, but also an interest in public ledger solutions in the form of the Storj network which uses such technology, but focuses on storage rather than sharing. The proposed solution, called SecuRES, is a communication protocol based on public ledger technology which acts similar to Bitcoin. A prototype based on the protocol has been implemented which proves the ability to share encrypted files with one or several recipients through a decentralized public ledger-based network. It was concluded that the SecuRES solution could do away with the requirement of trust in third parties for all but some optional operations using external authentication services. This is done while still maintaining data integrity of a similar or greater degree to trust-based solutions and offers the additional benefits of non-repudiation, high confidentiality and high transparency from the ability to make source code and protocol documentation openly available without endangering the system. Further research is needed to investigate whether the system can scale up for widespread adoption while maintaining security and reasonable performance requirements.

Projektet ämnar lösa problemen med oförnekbarhet, integritet och konfidentialitet när man delar känsligt data mellan parter som behöver lita på varandra utan inblanding av betrodd tredje part. Detta diskuteras för att besvara till vilken omfattning digitala resurser kan delas säkert i ett decentraliserat system baserat på publika liggare jämfört med existerande tillitsbaserade alternativ. En undersökning av nuvarande resursdelningslösningar visar att det existerar många tillitsbaserade system men även en växande andel lösningar baserade på publika liggare. En intressant lösning som lyfts fram är Storj som använder sådan teknologi men fokuserar på resurslagring mer är delning. Projektets föreslagna lösning, kallad SecuRES, är ett kommunikationsprotokoll baserat på en publik liggare likt Bitcoin. En prototyp baserad på protokollet har tagits fram som visar att det är möjligt att dela krypterade filer med en eller flera mottagare genom ett decentraliserat nätverk baserat på publika liggare. Slutsatsen som dras är att SecuRES klarar sig utan betrodda tredje parter för att dela resurser medan vissa operationer kan göras mer användarvänliga genom externa autentiseringstjänster. Själva lösningen garanterar integritet av data och medför ytterligare fördelar såsom oförnekbarhet, konfidentialitet och hög transparens då…
