Finding objects like music albums or wines in large databases is an inherently difficult problem, especially if users do not know exactly what they are looking for. We propose the use of Conceptual Spaces to lay out items spatially and provide a set of techniques for Zoomable User Interfaces to enable navigation within these spaces. Conceptual Spaces place items along meaningful dimensions, so ...

We give an overview of our recent results on model predictive control (MPC) for a class of non-smooth hybrid systems subject to perturbations. More specifically, we consider continuous and non-continuous piecewise-affine (PWA) systems. Most results on MPC for PWA systems involve non-perturbed systems. In this paper we consider perturbed PWA systems with bounded disturbances, i.e., PWA systems w...

Abstract The paper aims is to present the situation of Polish creative sector offices environment against background European examples. research material was developed on basis literature, survey and statistical research. Significant differences between foreign office buildings have been identified in scope workspace arrangements. results classify systematise new functional zones for employees,...

This paper applies fast sparse multidimensional scaling (MDS) to a large graph of music similarity, with 267K vertices that represent artists, albums, and tracks; and 3.22M edges that represent similarity between those entities. Once vertices are assigned locations in a Euclidean space, the locations can be used to browse music and to generate playlists. MDS on very large sparse graphs can be e...

This paper presents an efficient algorithin for coiiiputing the solution to the constrained infinite time linear quadratic regulator (CLQR) problem for discrete time systems. The algorithm coinbiiies multi-parametric quadratic programming with reachability analysis to obtain the optiinal piecewise affine (PWA) feedback law. The algorithm reduces the time necessary to compute the PWA solution fo...

OBJECTIVES To explore the employers' and promoters' perspective of health promotion quality according to the healthy workplace accreditation. METHODS We assessed the perspectives of 85 employers and 81 health promoters regarding the quality of health promotion at their workplaces. The method of measurement referenced the European Network for Workplace Health Promotion (ENWHP) quality criteria...
