This study concerns text, language, and learning in a linguistically heterogeneous upper secondary class in Sweden where students aged 16 to 17 are studying biology. One starting point for the dissertation is the importance of language in all school subjects. Another premise is that language as a resource for learning and communication is a high challenge for students who are studying through thei

Samhörigheten mellan de nordiska länderna är etablerad sedan länge och det är många som pendlar, flyttar eller gör affärer över gränserna i Norden. Det finns också ett omfattande politiskt och rättsligt samarbete. Trots detta uppstår det ibland juridiska svårigheter, ofta kallade gränshinder, för den som vill röra sig över de nordiska gränserna. Det kan exempelvis handla om problem i anslutning ti

The Swedish Joint Facilities create a common resource system for externalities of the individual property, such as common roads, bridges, residential services (waste disposal, car park, community places), irrigation and drainage schemes, and hunting ground. In a historical perspective, such facilities belonged to the village community, and remained as externalities when the society forced an inter

Popular Abstract in Swedish Den här avhandlingen handlar om kryptering, strömchiffer, metoder för att analysera (knäcka) och konstruera bättre chiffer. Det finns flera olika metoder för att hemliggöra meddelanden. Det klassiska sättet är att två personer som vill kommunicera delar en hemlig nyckel som används för att både kryptera och dekryptera meddelanden. Denna metod kallas symmetrisk krypteriStream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. The first attack is performed on SOBER-t16 and SOBER

The red admiral (Vanessa atalanta) is a migratory butterfly that can be found in North America, North Africa, Europe and some parts of Asia. In Europe the main part of the population spend winter in the Mediterranean region and the following spring leave this area to breed further to the north. At least one new generation is then produced in the summer region before they return to the south again

The authors present a tool for transistor sizing for the purpose of speed optimization. The tool, called SLOP (switch-level optimization), is based on a switch-level simulation program for CMOS circuits. Consequently, the results are always verified by simulation. It gives the delay-area curve and the final sizes of each transistor according to the maximum width limitation specified by the user. E
