Progression and Regression. Aspects of Advanced Swedish Students' Competence in English Grammar

This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. When the error score for the first test opportunity is compared with th

Degree-of-freedom evaluation of six-port antenna arrays in a rich scattering environment

It has been proposed that six co-located antennas, namely three electric and three magnetic dipoles, can offer up to a six-fold capacity increase in wireless channels, relative to that of single antennas. In other words, six degrees of freedom (DOFs) can be supported by co-located six-port transmit and receive antenna arrays. However, due to the complexity in designing and measuring such a six-por

Kommuners trafikstrategier och användning av hållbarhetsindikatorer

Within the framework of HASTA, a systematic study was conducted about Swedish municipalities’ traffic strategies and use of sustainability indicators to follow up the work on a sustainable transport system. This report analyzes the work of the municipalities with a traffic strategy in order to examine if the municipalities use sustainability indicators or not. Furthermore, the report analyzes in w

Cultural Development, Language Distribution, and Ecology in Pre-Columbian Amazonia

The thesis aims at creating a large-scale GIS database covering Amazonian prehistory between 2000 BC and AD 1700 in order to be able to test the hypothesis of ethnic circumscription described above. This database will be compiled of geographically positioned material from archaeology (datings, ceramic styles, tempering materials, rock art, anthropogenic soils, and other visual aspects of material

Effect of Pin Base-Fillet on Heat Transfer Enhancement of an Internal Blade Pin-Finned Tip-Wall

A common way to cool the tip is to use serpentine passages with 180-deg turn under the blade tip-cap. Improving internal convective cooling is therefore required to increase the blade tip life. In this paper, augmented heat transfer of a blade tip has been investigated numerically. The computational models consist of a two-pass channel with 180-deg turn and pin-fins mounted on the tip-cap, and a s
