This thesis introduces results from a design-based, task design research study in mathematics education, within which silent video tasks were defined, developed, and implemented in upper secondary school mathematics classrooms. It discusses a research ...

The cyclically-repeated song of the male humpback whale (Megaptera novaeangliae) is an important social display on their breeding grounds, functioning in male-male interactions and/or as a reproductive display to attract females. The songs are gradually ...

Background Sleep and physical activity are essential functions of human health. According to International recommendations, adolescents should sleep 8-10 hours each night and engage in moderate to vigorous physical activity for at least 60 minutes ...

This thesis is a study of the interface between sociolinguistics and syntax, focusing on 19 th -century Icelandic and the implementation of a national standard language from a syntactic perspective. Icelandic is noted for relatively successful and ...

Soils are an important natural capital that provides multiple services to humans including provisioning food, feed and fibre, water filtration and stabilizing climate. Soil security and soil sustainability are the basis for obtaining many of the UN ...

The purpose of this thesis is to develop spatio-temporal statistical models for glaciology, using the Bayesian hierarchical framework. Specifically, the process level is modeled as a time series of computer simulator outputs (i.e., from a numerical ...

Reduction of the size of magnetic bits for data storage, transfer and processing of information down to the nanoscale would lay the foundation for large advances in information technology, both in terms of processing speed and energy efficiency. ...

Scientific communities engaging in big data analysis face numerous challenges in managing complex computations and the related data on emerging and distributed computing infrastructures. Large-scale data analysis requires applications with simplified ...

In the ΛCDM concordance model cold and collision-less dark matter (CDM) accounts for about four fifths of the Universe’s total matter content, while visible baryonic matter makes up the final fifth. The ΛCDM model successfully describes how large ...

Thermal anomalies are observed at many volcanoes, resulting from geothermal and magmatic activity, and are usually difficult to quantify since the measurement of heat fluxes from the ground to the atmosphere is subject to large uncertainties. However, ...
