This paper deals with the problem of mobile device time synchronization with millisecond accuracy. We created a solution that will allow synchronizing time on mobile phones depending on accelerometer sensor precision. Our solution is suitable for multiple mobile sensor measurement where the time accuracy of synchronization between mobile phones is needed.(More)
It has been planned that the whole region of Slovak Republic's surface would be scanned, and there arose a need for storing the resulting data and making it publicly available. For this purpose, a scalable file-based database system for storing and accessing a large amount of geographic point cloud data was developed. The principle of the system was tested(More)
In this paper we describe fast and easy graph visualization layout we developed. We called it radius degree layout (RDL). RDL can be used for static and also for dynamic (interactive) visualization. RDL is easy to implement in 2D and 3D visualization, it is CPU efficient, also for large graphs, and we can easily orientate in graph using it. In this paper we(More)
We introduce a new fully automated online media monitoring system MNSight. We explain how the system works, for who is designated, its architecture and scalability. We show that it is easily accessible media monitoring system for the companies and also for general public which monitors at this moment Slovak internet media and collects over 2000 articles per(More)
