Photogrammetry and laser scanning, thanks to significant development in last years, are comparable surveying techniques to generate without object contact and with a precision commensurate with scale Digital Terrain Models (DTMs), a fundamental tool to detect, classify and monitoring landslides. The traditional way to survey the territory for landslide detection purposes is aerial or, in some c...

Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...

A digital search tree (DST) is a fundamental data structure on words that finds various applications from the popular Lempel-Ziv’78 data compression scheme to distributed hash tables. The profile of a DST measures the number of nodes at the same distance from the root; it depends on the number of stored strings and the distance from the root. Most parameters of DST (e.g., depth, height, fillup)...

introduction: the aim of this study was to evaluate the morphological changes and quantitatively assess the roughness of dentin after the ablation with a ytterbium-doped potassium yttrium tungstate (yb: kyw) thin-disk femtosecond pulsed laser of different fluences, scanning speeds and scanning distances. method: twelve extracted human premolars were sectioned into crowns and roots along the cem...

The external profile is among the first examined shape parameters of digital search trees in connection with the performance of unsuccessful search of a random query in the early 1970s. However, finer and important properties beyond the mean such as the variance and the limit law have remained unknown. In this extended abstract, we describe the first results for the asymptotic variance and the ...

The purpose of this study was to develop and evaluate a simple method to assess gantry rotation overrun in a single axial CT scanning. The exposure time in the axial scanning was measured at selected nominal rotation times (400, 700, and 1000 ms) using a solid-state detector, the RTI's CT dose profiler (CTDP). CTDP was placed at the isocenter and the radiation dose rate signal (profile) was rec...

Accurate terrain models are a crucial component of studies of river channel evolution. In this paper we describe a new methodology for creating high-resolution seamless digital terrain models (DTM) of river channels and their floodplains. We combine mobile laser scanning and low-altitude unmanned aerial vehicle (UAV) photography-based methods for creating both a digital bathymetric model of the...

Suppose you registered to a large scientific congress and you got from the Web site the conference program containing a long list of papers which will be presented. Which presentations do you choose to attend? Usually either you try to guess the most interesting talks from their titles and authors or you are forced to have a quick look at the conference proceedings. A recommender system able to...

Malware for current smartphone platforms is becoming increasingly sophisticated. The presence of advanced networking and sensing functions in the device is giving rise to a new generation of targeted malware characterized by a more situational awareness, in which decisions are made on the basis of factors such as the device location, the user profile, or the presence of other apps. This complic...

We present personalization aspects in information and video content retrieval and augmentation applications. Our goal is to explore the value of linking related content among different media such as TV and Web. Metadata extraction can make a great difference for personalized user experience. Annotations that provide title, genre, description, and cast can be greatly enriched with detailed infor...
