We propose a novel hybrid inertial sensors-based indoor pedestrian dead reckoning system, aided by computer vision-derived position measurements. In contrast to prior vision-based or vision-aided solutions, where environmental markers were used-either deployed in known positions or extracted directly from it-we use a shoe-fixed marker, which serves as positional reference to an opposite shoe-mounted camera during foot swing, making our system self-contained. Position measurements can be therefore more reliably fed to a complementary unscented Kalman filter, enhancing the accuracy of the estimated travelled path for 78%, compared to using solely zero velocities as pseudo-measurements. © 2013 by the authors; licensee MDPI, Basel, Switzerland.

The article discusses selected environmental pollution sources in the Badaševica river basin in relation to the quality state of Badaševica River and of Gulf of Semedela. The Badaševica River represents the major freshwater inflow of water into the Gulf of Semedela; consequently, it affects the physico-chemical and bio -logical properties of the sea, but also the flow of polluted water represents a major source of pollution of water and sediments in gulf. The concerned area of Gulf of Semedela is, due to its geographical position, shallowness and weak currents, an extremely sensitive area with low self-cleaning capacity, which further increases the impact of pollution from the hinterland. Fugitive municipal wastewater discharges and leachate from agricultural lands are major polutants. Source

Article discusses causes and consequences of Quaternary sea-level changes. It describes all major markers of the process, which have been ascertained with isotopic studies and observations of geomorphologic particularities, with special interest in Adriatic region. Article also presents some results of sonar surveys in the Slovenian sea, which proved to be valuable in research of underwater relief features, formed before the last sea trangression. Source


Due to a dense population and the presence of various activities, among which tourism and port activities must be highlighted, the Slovenian coast is subject to constant changes. This article analyzes the extent of these changes between 1954 and 2010, which coincides with a time of major coastline changes resulting from intense development of tourism and the commercial port. The analysis was based on a comparison of aerial photographs from 1954 and 2010. The changes were determined and measured on transects 50 meters apart. The land area gained and lost during this time was also calculated and the coastline was classified into four different types based on the level of naturalness and anthropogenic transformations. © 2014,Anton Melik Geographical Institute.
