We describes theoretical and experimental results for the extrinsic calibration of sensor platform consisting of a camera and a laser range finder. The proposed technique requires the system to observe a planar pattern in several poses, and the constraints are based upon data captured simultaneously from the camera and the laser range finder. The planar pattern surface and the laser scanline on...

Detection of early symptoms in cervical cancer is crucial for early treatment and survival. To find symptoms of cervical cancer in clinical text, Named Entity Recognition is needed. In this paper the Clinical Entity Finder, a machine-learning tool trained on annotated clinical text from a Swedish internal medicine emergency unit, is evaluated on cervical cancer records. The Clinical Entity Find...

A dynamic systenl for integrating natural language and vision is presented, specifically aimed toward supporting an interpretative model and a set of conceptual tools, which may consistently represent those qualitatively different aspects of natural language, which are opaque and therefore difficult to identifi’. Qualitative reasoning about conmmnication via natural language is being proposed a...

Abstract We apply a new galaxy group-finder to the Main Galaxy Sample of SDSS. This algorithm introduces freedom assign halos galaxies that is self-calibrated by comparing catalog complementary data. These include clustering data and measurements total satellite luminosity from deep-imaging present constraints on galaxy-halo connection for star-forming quiescent populations. The results group d...

Current cultural, social, and economic trends challenge traditional concepts of learning and lifelong learning. This paper draws on the twofold nature of learning in a knowledge society and explores options for technological support. The concept of Second-Order Learning Objects is introduced as a potential means to foster generative learning. Generative learning goes beyond that what is already...
