The paper consists of a method to implement a control system algorithm for an inertia wheel inverted pendulum. Like any control system application, the transfer function of the plant should be known in order to design the proper controller. The key point of this paper is that the behaviour of the plant is consider unknown, so a system identification should be done at first. Even if the classical way to obtain the transfer function is by writing the physical equations, the result obtained from system identification...

Fused Deposition Modeling (FDM) is one of the most used technology in the 3D printing field. There is many kind of 3D printers with different design and parameters, such work temperature, deposition speed and others. All of these parameters affect the final parts. Produced parts are made from different materials and therefore there are also different mechanical properties. So it depend what for the produced parts are designed, if there are just for design introducing or even for real use as conventional produced p...

Today, growing number of ransomware attacks from the cyberspace is getting more and more attention as the danger of immediate closing of business for attacked organizations rises dramatically. High level encryptions used by current versions of ransomware makes it almost impossible to be decrypted in the real time and probability of production going live again for attacked organization could be low. Estimated revenue up to 1 billion USD in 2016 makes this type of cybercrime activity very popular within the hackersп...

In this contribution, the authors describe a novel method of visualizing any 3D object into a 2D seamless picture with the use of cartographical principles. The method uses properties of a sphere with reflective inner surface, in which a 3D object and capturing camera are placed. A sphere surface is consequently unfolded using cartographic projection allowing to see the whole object in 2D. The method can be applied to any objects, preferably those of non-human origin, e.g. trees with leaves, cave systems, EarthпїЅ...

Currently, the design and development of the user interface is important, but at the same time, an empirical process. Despite the attempts of many authors to give recommendations on the correct design of the interface appearance, there are no recommendations on how to relate the domain and interface, and build the latter without losing the sense of the user's activity. Unlike the existing approaches in this area, the proposed approach to the semantic design takes into account the activity of the user in the domain...

Steganography is part of security science that deals with art of data hiding. Modern steganography can serve as an effective tool for hidden data transfers or watermarking for various computer formats, like JPEG, PNG, and MPEG. But it can be misused for stealing data or information transfer in illegal activities too. Most of today available steganography tools are free for use with easy user interface. This significantly increases the risk of exploiting in business sector. Revealing this data is very difficult and...

Specific models and storage technologies which is possible to save domain semantics are required to create configurable information systems. This is why modern researchers talk about the high cost of domain models in comparison with a program code. But they don't suggest any approaches for including this model as a component of the system itself. Existing approaches for domain modeling during the transition to final stages of a system life cycle tend to lose the semantic component of the data. They only allow to p...
