Cílem této práce bylo analyzovat funkcnost routování síte Miwi Pro. Pro potreby analýzy jsem navrhl zpusob získávání statistických dat z jednotlivých prvku síte a urychlený mechanismus obnovení routovacích pravidel pri premístení zarízení v rámci síte. Sber statistických dat vyžadoval návrh a implementaci protokolu pro výmenu informací mezi koordinátory v rámci síte. Pro obnovu routovacích pravidel po premístení zarízení jsem navrhl algoritmus, který obnoví pravidla pro každý prvek v síti a tím povolí testování jednotlivých prvku síte mimo jejich koncové stanovisko.The main goal of this thesis was to analyze routing functionality of MiWi Pro network. I needed to find a way to get statistical data from network items for purpose of analysis and develop faster mechanism to reload routing rules after replacing part of the network. Gathering of statistical data required design and implementation of protocol needed to exchange information between coordinators inside the network. I developed an algorithm which reloads routing rules after replacing part of network and allows to test individual network items outside of their final location in the network.

2-Chloro-N-(2,6-dimethyl­phen­yl)benzamide

In the title compound, C15H14ClNO, the dihedral angle between the benzoyl and the aniline rings is 3.30 (18)°. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into chains running along the a axis

UNIFORM SMARTPHONE CONTROLLER FOR WEB-BASED VIRTUAL REALITY PURPOSES

This work introduces a uniform smartphone controller interface integrated into LIRKIS G-CVE web-based global collaborative virtual environments. In general, VR controllers provide various kinds of interaction techniques to manipulate virtual objects. Mostly, those aim focus on controlling the virtual context and the interaction with 3D GUI integrated in the virtual environment. With respect to web-based virtual reality, the progress in development of uniform interfaces is raising thanks to emerging web technologies and frameworks with cross-platform support. Although there are many manufacturers of VR controllers, their usage is often limited only for specified display device. Our intention is to cover multiple devices through only one simple controller interface, that is capable to provide a variety of interactions for web-based VR. In this study we proposed Enhanced Smart Client Interface designed for providing fully immersive interaction through smartphones. We performed several experiments focused on user experience and usability under two cloud platforms. Results obtained from experiments performed in our study confirm that utilization of our interface is mostly affected by the server response time. Based on the results this solution is suitable for further development and improvements

Mixed Reality: A Known Unknown

Mixed reality (MR) is an area of computer research dealing with the combination of real-world and computer-generated data (virtual reality), where computer-generated graphical objects are visually mixed into the real environment and vice versa in real time. This chapter contains an introduction to this modern technology. Mixed reality combines real and virtual and is interactive, real-time processed, and registered in three dimensions. We can create mixed reality by using at least one of the following technologies: augmented reality and augmented virtuality. The mixed reality system can be considered as the ultimate immersive system. MR systems are usually constructed as optical see-through systems (usually by using transparent displays) or video see-through. Implementation of MR systems is as marker systems (real scene will be added with special markers. These will be recognized during runtime and replaced with virtual objects) or (semi) markerless systems (processing and inserting of virtual objects is without exact markers. Additional information is usually needed, for example, image and face recognition, GPS coordinates, etc.). The chapter contains also a description of mixed reality as an advanced computer user interface and the newest collaborative mixed reality
