Low energy buildings have attracted lots of attention in recent years. Most of the research is focused on the building construction or alternative energy sources. In contrary, this paper presents a general methodology of minimizing energy consumption using current energy sources and minimal retrofitting, but instead making use of advanced control techniques. We focus on the analysis of energy savings that can be achieved in a building heating system by applying model predictive control (MPC) and using weather predictions. The basic formulation of MPC is described with emphasis on the building control application and tested in a two months experiment performed on a real building in Prague, Czech Republic

Novák, A. - Simon, L. - Kadlec, F. - Lotton, P.: Nonlinear System Identification Using Exponential Swept-Sine Signal. IEEE Transactions on Instrumentation and Measurement. 2010, vol. 59, no. 8, p. 2220-2229. ISSN 0018-9456.

The work is the result of the Antonin Novak's double degree Ph.D. in collaboration between the Czech Technical University in Prague and Laboratoire d'Acoustique de l'Université du Maine (LAUM).

In this paper, a method for nonlinear system (NLS) identification using a swept-sine input signal was proposed. The method uses a nonlinear model, namely, the generalized Hammerstein model made of power series associated with linear filters. Simulation results showed that the method identifies the nonlinear model of the system under test and estimates the linear filters of the unknown NLS. The method has also been tested on a real-world system: an audio limiter. Once the nonlinear model of the limiter is identified, a test signal can be regenerated to compare the outputs of both the real-world system and its nonlinear model. The results showed good agreement between both model-based and real-world system outputs.

Although the published method has been originally designed for the field of audio engineering, its efficiency and simplicity represent a high potential for nonlinear systems identification in many field of physics. For instance, the method has been successfully used for non-destructive testing of diverse materials.The method is now used not only in field of science and research, but it has also found its place in industrial application. A French company Orkida Audio (info@orkidia-audio.com), a start-up dealing with an innovative loudspeaker technology, has adapted the method as a main measurement tool.

3D+time computed tomography can provide patient-specific motion information for radiotherapy planning. The motion is extracted through image registration. We have improved the robustness of the image registration by using a global problem formulation. The work has been done in collaboration with the Leon Berard Cancer Center, Lyon, which permits us to test our methods on real patient data. The importance of this problem for the clinical practice is also attested by the number of citations (32 according to WoS, 54 according to Google Scholar).

Hanzálek, Z. - Burget, P. - Šůcha, P.: Profinet IO IRT Message Scheduling With Temporal Constraints. Industrial Informatics, IEEE Transactions on. 2010, vol. 6, n

Published in WoS-Q1 journal with 11 citations in WoS (more than IF of the journal, which is 8.785) including citiations in 4 other IEEE Transactions. 28 heterocitations by Scholar. The article describes an algorithm to create a message schedule for Profinet IRT, which was unique at the time of the publication. This was the primary work on Profinet IRT, which continued in a series of other activities such as the establishment of the Certified Profinet Training Centre (certified by Profibus & Profinet International) in 2011. The related Certified Profinet Engineer course has been provided for more than 50 participants from Czech Republic, Austria, Turkey, India and the total turnover in terms of commercial agreements has been more than 1 million CZK since then. In 2014 another commercial project for 0,5 million CZK has been done for Profibus Nutzerorganisation, whose objective was to develop a tool, which is called IRTcheck, to check the Profinet IRT message schedule with respect to other parameters describing the characteristics of the involved devices. This tool has been used by major automation manufacturers like Siemens, WAGO, Phoenix Contact, Beckhoff, Molex, Hilscher whose development teams have been using the tool. From the point of view of PI an important fact is that the parameters generated by different Profinet IO Controllers, i.e. from different manufacturers, comply with the Profinet standard and thus the interoperability of the devices and the controllers is ensured. The tool is available for the members of PI for free.

We present a method to localize a thin surgical tool such as a biopsy needle or a microelectrode in a 3-D ultrasound image. This is an important practical problem, with application in computer guided surgery and medical robotics. The method is both faster and more robust then previously known alternatives, by combining shape an intensity modeling, random sampling and consensus (RANSAC), and local optimization. The work has 17 heterocitations according to WoS (35 according to Google Scholar). It is a result of a collaboration with the CREATIS team at INSA, Lyon, France and an ultrasound equipment manufacturer GE Medical Systems.

The paper presented at prestigious Faraday Discussions conference (conference with 100 years tradition; 5 minutes of presentation is followed by 30 min discussion, which is recorded and published; IF of journal 4.6) deals with tribological behaviour of novel smart low-friction coatings with self-adaptive nanostructure. We have used combination of advanced surfaces characterization to describe and understand frictional mechanism of the coatings in different environment. Alloying of WSC self-adaptive film with chromium significantly reduces its performance in humid air. Based on our experimental findings, we question the role of doping metal as oxygen getter during deposition or sliding in humid air. In discussion, we challenge historical model of friction reduction with load based on material shear strength; we believe that nanoscale tribochemistry is key factor controlling tribological behaviour. Our finding indicate that ultrathin tribolayer (nanometer scale) is responsible for low friction. It opens new possibilities for theoretical simulations, since we can downscale problem to few atomic layers (see our last work on simulation, e.g. Levita et al, J Phys Chem C 118 (2014) 13809–13816 or Cammarata&Polcar, Inorganic Chemistry 54 (2015) 5739–5744).
