Haptic 3D object recognition: A study with blind users

We report results from a subset of an extensive study of the performance of blind persons in different haptic environments. Test tasks included in the study were recognition of simple geometrical objects, realistic VRML models, mathematical surfaces, a si

Unraveling process in the laboratory

Focuses on processes brought about in laboratory settings, either processes implying adaptation to strange or contradictory stimulation. or microprocesses underlying the construction o funfamiliar aspects of the outside world. These methods hae been utilized to an increasing extent, in personality and clinical psychology, as efficient diagnostic tools.

Evidence and transparency in the open public services-reform: perspectives for the third sector

The concepts of ‘transparency’ and ‘evidence of what works’ are key features in the implementation and success of the open public service policy. This paper explores, from the perspective of the third sector, the meaning of these concepts and how we can expect them to be operationalized. Initially, an implementation guided by evidence and transparency seems reasonable and ethical. The practical me

Sum rules and physical bounds on passive metamaterials

Frequency dependence of the permittivity and permeability is inevitable in metamaterial applications such as cloaking and perfect lenses. In this paper, Herglotz functions are used as a tool to construct sum rules from which we derive physical bounds suited for metamaterial applications, where the material parameters are often designed to be negative or near zero in the frequency band of interest.

Couples' approaches to changes in everyday life during the first year after stroke.

Aim: The aim of the study was to identify and describe two couples’ approaches to changes in everyday life during the first year after a stroke. An additional aim was to describe how the couples viewed rehabilitation as well as their own personal training relative to changes in everyday life during the first year at home after stroke. Method: The study design was a prospective longitudinal case st
