The subject of this article is to find out whether virtual reality can affect phobia of spiders. For this pre-research were performed 20 experiments on a small sample of subjects. Two approaches were used to measure during the experiments. The values of results are represented by this post.

This paper deals with the topics of heat consumption in the municipal heat distribution systems and problems linked with modeling and simulation of systems providing heat supply. These systems will be called SHDC (System of Heat Distribution and Consumption). The significant problem in the controlling mechanism of such systems consists in transport delay of transferring heat media. As a result the control mechanism must operate in prediction kind of mode. Essential parameters, or control variables, are temperature of heat carrier and its flow rate. Their time behavior must be predicted for efficient control of the whole heat energy supply. Main focus will be placed on description of the proposed and implemented computer model of the heat distribution system in the selected agglomeration. This model is proposed as a discrete simulation model and implemented in the form of computer application. Model has been tested on real operational data.
