I t is well known tha t copper (I I) acetate monohydrate has a binuclear bridged structure [1, 2] in which two copper atoms are bonded by four acetate groups and the water molecules are linked to copper atoms in axial terminal positions (Fig. 1). The salient feature of this structure is the close approach of the neighbouring copper atoms Cu—Cu = 2.64 Á, owing to which there is direct copper—cop...

This paper presents two approaches to modelling of mobile robot dynamics. First approach is based on physical modelling and second approach is based on experimental identification of mobile robot dynamics features. Model of mobile robot dynamics can then be used to improve the navigational system, especially path planing and localization modules. Localization module estimates mobile robot pose ...

In this paper a predictive controller for real-time target tracking in mobile robotics is proposed based on adaptive/evolving Takagi-Sugeno fuzzy systems, eTS. The predictive controller consists of two modules; i) a conventional fuzzy controller for robot motion control, and ii) a modelling tool for estimation of the target movements. The prediction of target movements enables the controller to...

The problem of species recognition in paleoanthropology has been the subject of numerous studies. In the current study, we have used the complex topography of the mandibular fossa to assess its potential as a species-specific indicator. Six landmarks were registered using a microscribe 3Dx digitizer on four extant species: Pan paniscus, Pan troglodytes, Gorilla gorilla, and two ethnical groups ...

An automatic system aimed at producing a compact tridimensional description of indoor environments using a mobile 3D laser scanner is described in this paper. The resulting description is made up of a Multi-Level Map (ML map) and a series of planar patches extracted from the map. We propose a novel plane detection algorithm, based on the efficient RANSAC algorithm, that operates directly over t...

A high-quality human-robot interface is essential for the success of search and rescue operations in urban environments that are too challenging for fully-autonomous operation. Teleoperating multiple robots greatly increases the complexity of the human’s cognitive task, since the operator’s concentration is divided among multiple robots. Thus, simply adding more robots to the system does not ne...

In this paper we consider problem of exploration and mapping of unknown polygonal environments. To construct a map of unknown environment we first must have exploration algorithm, and we have to choose a map representation method. Unknown environment needed to be explored is an indoor office environment. We use line map representation method since it is easy to represent office environment usin...

INTRODUCTION This study assessed the three-dimensional changes in the dental arch of patients submitted to orthodontic-surgical treatment for correction of Class II malocclusions at three different periods. METHODS Landmarks previously identified on upper and lower dental casts were digitized on a three-dimensional digitizer MicroScribe-3DX and stored in Excel worksheets in order to assess th...

Currently, two-dimensional photographs are most commonly used to facilitate visualization, assessment and treatment of facial abnormalities in craniofacial care but are subject to errors because of perspective, projection, lack metric and 3dimensional information. One can find in the literature a variety of methods to generate 3-dimensional facial images such as laser scans, stereo-photogrammet...

We present a fast multi-robotic exploration methodology for 2D and 3D terrains. An asynchronous exploration strategy is introduced which shows significant improvements over the existing synchronous ones. A per-time visibility metric is being utilized by the algorithm. The metric allots the same weight for points for next view whose visibility over time ratios are equal. The outcome of this is t...
