Nowadays, when the requirements for the production of investment castings are increasingly high, it is necessary to accurately predict and remove defects from the process of casting the metal itself, but also during the production of wax blades. Accuracy and especially the ability to predict defects is key to this production. This paper deals with the current theme of wax mix properties for blade injection simulation. One of the main parameters of a properly executed simulation is to enter the correct initial parameters. For this reason, this article explores the properties of wax mixtures and their subsequent implementation in the process of simulating the blade injection process. [ABSTRACT FROM AUTHOR]

Virtual environments and scenarios which are able to create fully immersive alternative visual, haptic acoustic and even olfactory experience is contained in increasing number of researches nowadays. Potential of appropriate application could be very high. Very specific fusion of sciences is described in this paper. Particularly, immersive virtual reality and technology of polygraph connection considerations are analysed, moreover the framework of this synergy is proposed. Furthermore, suitable methods of virtual crime scenario fast reconstruction are reviewed and possible next research steps are exposed. [ABSTRACT FROM AUTHOR]

The paper deals with the problem creation of a simulation system. The problem is that existing systems, such as Starlogo Nova, Swarm, Mason, TeamBots, Ascape, Stage, V-REP, do not allow in the complex to simulate the physical properties of the object, implement elements of robots, maintain communication between agents, maintain a large number of agents, support the use of clusters and use social-oriented libraries. This ultimately significantly reduces the computational speed. To overcome these difficulties, the structure of a new system of simulation is proposed. At the center of the new system is a calculation module with the possibilities of parallelizing the computational process within a single computer. The module supports distributed computing, if the system is used in a computer network. A variant of the structural scheme of the modeling system is also offered, which includes a calculation module, consisting of a parallel programming support module, a distributed computing support module, an agent module and a simulation environment module. In addition, the proposed structural scheme includes a visualizer, combining the controller/management console and the graphic user interface. The functioning of the system depends on the choice of the basic algorithms that ensure the operation of the simulation system. Offered structure of the system of imitation simulation will allow raising the speed of calculations. Modular system makes it possible to change the configuration of the system with the replacement of some functioning algorithms to others. At the same time, the effective operation of the simulation system, according to the proposed scheme, is not possible without the development of individual software, using high-level programming languages such as C ++ or Java.
