Low rank approximation is an important tool in many applications. Given an observed matrix with elements corrupted by Gaussian noise it is possible to find the best approximating matrix of a given rank through singular value decomposition. However, due to the non-convexity of the formulation it is not possible to incorporate any additional knowledge of the sought matrix without resorting to heuris

The purpose of this research is to conduct a critical study which focuses on getting deeper insights into in-application advertising, especially, to understand the details of making in-application advertising, and to develop the existing advertising model for applying to the in-application advertising specifically.

Title: Virtual Reality as presentation tool for architects Authors: Adrian Norlund och Lisa Rask Supervisor: Fredrik Wikberg, Department of Building Construction, Faculty of Engineering (LTH) Question formulation: - Will the audience get a better idea of an object in VR compared to current presentation techniques? - What is most useful for architects, Oculus Rift, Google Cardboard or VR room (CAVE

The purpose of this thesis is to develop knowledge about visual information seeking and how it might be affected by socio-technical circumstances, with its focus on GeoGuessr players’ research through Google Street View. The study asks two research questions: 1. How do GeoGuessr players use Google Street View to do research? and 2. How can Google Street View’s socio-technical circumstances affect

The Learning with Errors problem (LWE) is one of the main candidates for post-quantum cryptography. At Asiacrypt 2017, coded-BKW with sieving, an algorithm combining the Blum-Kalai-Wasserman algorithm (BKW) with lattice sieving techniques, was proposed. In this paper, we improve that algorithm by using different reduction factors in different steps of the sieving part of the algorithm. In the Rege

Drawing on modelling of age at death in skeletal remains, this article unveils hitherto unrecognized demographic patterns in the Nordic Corded Ware complex. This population formed part of the European Corded Ware complex that has been linked to disruption observed in the archaeological and genetic record. The newly developed methods of transition analysis 3 (TA3) and death rate ratio (DRR) were usDrawing on modelling of age at death in skeletal remains, this article unveils hitherto unrecognized demographic patterns in the Nordic Corded Ware complex.
