Sammanfattning : This thesis' main theme is successful principal leadership in secondary schools within the Swedish education system. Successful principal leadership is examined from three perspectives: What are the processes of a successful principal? Do the leadership processes relate to successful academic and social outcomes of schools? What are the prerequisites for successful principal leadership? The Frame Factor Model and the three concepts of prerequisites, processes and outcomes constitute an overarching framework. LÄS MER
Sammanfattning : Word embedding is a technique for associating the words of a language with real-valued vectors, enabling us to use algebraic methods to reason about their semantic and grammatical properties. This thesis introduces a word embedding method called principal word embedding, which makes use of principal component analysis (PCA) to train a set of word embeddings for words of a language.

Sammanfattning : In a real-time system, it is crucial to ensure that all tasks of the system hold their deadlines. A missed deadline in a real-time system means that the system has not been able to function correctly. If the system is safety critical, this could potentially lead to disaster. LÄS MER
Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER
Sammanfattning : Ice sheets have strong influence on the climate system. Numerical simulation provides a mathematical tool to study the ice dynamics in the past and to predict their contribution to climate change in the future. Large scale ice sheets behave as incompressible non-Newtonian fluid. LÄS MER
