A novel, very simple monopulse feed is presented consisting of a microstrip-patch antenna and a monopole, both inside a single cup. The patch is used for the sum (data) channel while the monopole provides the difference (tracking) information. The proposed monopulse feed can be used with circularly-polarized signals and/or in dual-polarization systems, where the two orthogonal linear polarizations carry independent, incoherent information.

COBISS.SI-ID: 11250004This chapter presents the methodology for transformation of behavioural cues into Social Signals (SSs) in human-computer interaction that consists of three steps: acquisition of behavioural cues, manual and algorithmic pre-selection of behaviour cues, and classifier selection. The methodology was used on the SS class {hesitation, no hesitation} in the interaction between a user and video-on-demand system. The first step included observation of the user during interaction and obtaining information about behavioural cues. The second step was the manual and algorithmic pre-selection of all cues that occurred into a subset of most significant cues. The last step involved the selection of an appropriate classifier. For example, a logistic regression model was obtained in combination with four features. In this way, we proved the resulting features explain over 90% of the variability of the hesitation.

COBISS.SI-ID: 10970964Optical satellite images are becoming increasingly important in remote observation of environment, and they find practical use in fields such as forestry, agriculture, civil protection, and insurance. In response to the increasing need for automatic and fast satellite image processing we have developed and implemented a fully automatic image processing chain STORM that performs all processing steps from sensor-corrected optical images to web-delivered map-ready images and products without operator's intervention. The paper focuses on the adaptation of the processing chain to very high resolution multispectral images, and demostrates the usage of WorldView2 satellite data.

COBISS.SI-ID: 38464301Motion tracking systems, in connection to the biomechanical biofeedback, help in accelerating motor learning. Requirements about various parameters important in real-time biofeedback applications are discussed. Special focus is given on feedback loop delays and its real-time operation. Optical tracking and inertial sensor tracking systems are presented and compared. Real-time sensor signal acquisitions and real-time processing challenges, in connection to biomechanical biofeedback, are presented. This paper can serve as a starting point for determining the adequate combination of technical equipment and its specifications that work favorably for the operation of the planned real-time biofeedback application.

COBISS.SI-ID: 11253332User context and user location in particular play an important role in location-based services (LBS). The location can be determined by various positioning methods. These are typically evaluated with average positioning error or percentile values, which are not the most suitable metrics for evaluation of how a positioning method functions in the semantic space. Therefore, we propose a new method for evaluation of positioning accuracy in the semantic space. We focus on two types of semantic user locations that are widely available in urban areas: the street address and the categories of the surrounding points of interest (POIs). We demonstrate its use on ten different positioning methods. The evaluation suggests that approach with the street addresses is more promising approach due to either sparse or unevenly distributed POIs.
