In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by the scientists of Riga Technical University (RTU). LAMO comprises geological and hydrogeological data provided by the Latvian Environment, Geology and Meteorology Centre (LEGMC) for the active groundwater zone of Latvia. In 2013–2015, LAMO was notably upgraded. The density of hydrographical network (rivers, lakes) wa...

The studies reported here used an interference paradigm to determine whether a long-term consolidation process (i.e., one lasting from several hours to days) occurs in the learning of two implicit motor skills, learning of a movement sequence and learning of a visuo-motor mapping. Subjects learned one skill and were tested on that skill 48 h later. Between the learning session and test session,...

The goal of this chapter is to present a design space for tools and methods supporting remote usability evaluation of interactive applications. This type of approach is acquiring increasing importance because it allows usability evaluation evenwhen users are in their daily environments. Several techniques have been developed in this area for addressing various types of applications that can be ...

Ziel dieses Graduiertenkollegs ist die interdisziplinäre Erarbeitung und klinische Einführung neuer computergestützter Verfahren in der Weichteilchirurgie. Möglichkeiten der Operationsplanung, der interaktiven Bildgebung, der Telemanipulation, der Robotik und der Navigation führen zu tiefgreifenden Veränderungen des chirurgischen Arbeitsplatzes und werden längerfristig auch das Leistungsprofil ...

— In this paper, we describe a new methodology applied to solving in-class problems. The aim is to increase the student's participation and motivation, and, consequently, the acquisition of knowledge and skill in digital systems. We present the use of an interactive docent tool, Educlick, which has been adapted to these problems' classes. Educlick is based on the use of electronic answer remote...

Early Intervention (EI) services for children birth through two years of age are mandated by Part C of the Individuals with Disabilities Education Act (IDEA); however, personnel shortages, particularly in rural areas, limit access for children who qualify. Telerehabilitation has the potential to build capacity among caregivers and local providers as well as promote family-centered services thro...

Examples show that integral forms can be efficiently proved positive semidefinite by the WDS method, but it was unknown that how many steps of substitutions are needed, or furthermore, which integral forms is this method applicable for. In this paper, we give upper bounds of step numbers of WDS required in proving that an integral form is positive definite, positive semidefinite, or not positiv...

Nowadays, Effectiveness and benefits of mobile phone technologies appeared more than expected. During the recent decade, using of mobile phone improved from telephone call tools to a remote control, transfer messages and financial transactions tools. One of the most important challenges in the mservices area is the security issue. Different papers have discussed various aspects of secured netwo...

Recently, functional endoscopic sinus surgery is the state of the art in the surgical treatment of endonasal pathology. For a more accurate access planning including 3D measures of the cavity, especially in complex cases of tumor diseases, a segmentation of the paranasal sinus is certainly a useful tool. Unfortunately, this structure is quite complicated and difficult to segment. In our contrib...
