Robotic soccer, and RoboCup in particular, has been a research topic for almost a decade, with an upsurge during the last few years. RoboCup is usually viewed as being a means to research, education, and dissemination. We analyse RoboCup in each of these perspectives. Firstly, we show that RoboCup is a good research challenge. Second, we conclude that RoboCup is not always useful in education. ...

Background. Environmental pollution with toxic compounds poses a danger to nature and humans. Various technologies for soil purification from metals are being developed. Objective. The work was aimed study the possibility of lawn grass using Cr(VI). Methods. Plant seeds (Festuca rubra L. 45%, Festuca arundinacea Schreb. 25%, Lolium perenne 20%, Poa pratensis 10%) were sown in container at 24 °C...

     Developing strategies to tackle water stress in lawns in arid climate regions is significantly important. In such conditions, using growing media amendments as well as native plants can relieve drought stress in different growing stages of the plants. This study was carried out to investigate the effects of some types of soil amendments on the emergence and early seedling establishment of ...

We present a method for navigating an autonomous agent based on the textures present in an environment. Specifically, the autonomous agent in question is that of a robotic lawn mower. If we can successfully differentiate the textures of the cut and uncut lawn surfaces, then we can track the boundary between them and mow in a pattern as a human would. The system uses the wavelet transform as the...

The authors give a history of the so-called tennis ball problem, and discuss its relation to lattice path enumeration. We also prove a conjecture related to a solution of the symmetric case, namely when the number of balls removed each turn is exactly half the number inserted. Key words: Tennis Ball Problem, lattice path, Finite Operator Calculus 1 The Tennis Ball Problem-History The tennis bal...
