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. We tested the implemented solution on the...

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 and proved to be sufficient in most situations,...

This paper deals with the problem of storing and distribution of geographic point cloud data. A scalable file based database system for storing and accessing a large amount of point cloud geographic data was developed. The principle of the system is briefly described and the results of experiments with different file formats and their impact on the overall performance of the system as well as to space...

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 describe RDL philosophy, implementation,...
