Modeling the tumor growth under angiogenic inhibition is an important step towards designing tumor treatment therapies based on mathematical tools. Our goal is to create a model for tumor growth that describes the underlying physiological processes adequately while being as simple as possible. We propose a second-order model containing linear terms and one bilinear term modeling the dynamics of tumor volume and inhibitor level, and work out the parametric identification process for the model. The parametric identification of the model is done using measurements from experiments on C57Bl/6 mice with C38 colon adenocarcinoma treated with bevacizumab. The control group of the mice received one injection at the beginning of the experiment, these measurement data are used for parametric identification, while the case group of mice received injection at each day of the treatment, these measurements are used to validate the model. The validation showed that the proposed model is capable of describing the tumor growth dynamics.

In this paper, we present the important role of alpha band for the evaluation of the drowsiness degree. By filtering the alpha band and by using the power spectral density of that same band, our data were analyzed using the percentiles as measures of dispersion. A threshold discriminating the two states was found, which helped to highlight the area of the brain responsible for the state of drowsiness for driver. So, in this work, we look to develop a drowsiness monitoring system in the goal to participate in reducing of the big number of road accidents to estimate the drowsiness level by analysis of EEG (electroencephalography) signals records. Finally, the algorithm developed in this work has been tested on twelve samples from the Physionet sleep-EDF database.

Solving the inverse heat conduction problem is the key to determining heat flux on the surface of an object. Unfortunately, it is a typical ill-posed problem, as only numerical approximation methods are available for finding an approximate solution. It is common to use some heuristic methods, such as genetic algorithms, particle swarm optimisation, etc. Although the main mechanisms of these approaches are well-known, the practical implementations raise several questions about the free parameters (population size, elitism, mutation probability/range, etc.). This paper presents the results of several experimental tests to find the appropriate attributes of a genetic algorithm based approach to quickly and reliably solve the inverse heat conduction problem.

The task to distinguish between soft tissues by testing their mechanical properties is often referred to as the primary cognitive role of haptic devices. It is a common view that today's surgical simulators that are using haptic interfaces should rely on simple mechanical models of soft tissues, instead of complex, parameterized finite element models, thus enhancing real-time operation and focusing on the most representative mechanical effects. This paper proposes a user-trial validation method for tissue models and their polytopic representation by creating an experimental framework for soft tissue characterization, using the da Vinci Research Kit. The characterization methdodology relies on haptic feedback from the manipulated real tissue, extending the functionality of surgical simulators using virtual tissue models created by the previously proposed soft tissue modeling method. Results showed that the tissue model represents the tissue behavior sufficiently well for use in haptic simulators, based on user experience. Furthermore, it was concluded that silicon phantoms can mimic the behavior of real tissues in various surgical scenarios, especially when using teleoperation manipulation.

Oil for electricity generation, burning of coal, heat production is the largest sources of greenhouse emission that cause climate change worldwide. Therefore the diffusion of solar PV technologies has become a crucial component for both climate change mitigation and adaptation of the electrical system on a global scale. In this survey, we analyzed the state of the art of the present large scale Photovoltaic application (technology, size, efficiency, cost). We investigated also in detail the commercially available new PV technologies, e.g.: Thin film, Dye-sensitized solar cells (DSSC), organic PV cells (OPV), and their near future's application perspectives. Finally, this paper summarizes the research findings of the new PV technologies' challenge that need to be overcome, on particular stability, efficiency, lifetime and degradation. In order to realize their potential as an economically viable path to harvesting energy from sunlight.

This paper presents the current progress in acquiring and analyzing the data, obtained from smartphone sensor measurements during a drive with a car. The main aim of the research is to create generic rules to identify road state and its quality. Previously, the mobile application has been created, and measurements began. Currently, we acquired data from more than 500km of daily driving and created a road map using binning and basic clustering. The aggregated values on the map contain information about speed, location and peek linear 3-axial acceleration. In the future, we expect to apply Kalman filtering for cleansing the acceleration data and to continue with evaluating other quality metrics.

During the last decade many information systems started applying various biometric identification modules. This type of identification is secure and provides a real possibility to protect a system from an unapproved access. The paper presents a newly developed biometric identification approach that is suitable for many biometric signals. This work describes an evaluation of the approach on low-frequency eye tracking data that had been collected using 30Hz eye tracker as well as a MATLAB library realizing the approach that had been developed.

In architecture, in special tasks of industrial robotics applications, in navigation and control systems of military technology, in solution for manipulation problems of space exploration in many cases we have to deal with definition, measurement of specified points of space. From measurement technology point of view, it is regarded as a classical solution to solve a problem by application of calculation according to the principle of three-dimensional triangulation. A newer possible solution is provided by application of imaging systems, which may give good results with proper software support. In our article we deal with measurement technology problems of a special area. Measurement of parameters of spectacle elements for pyrotechnics is important from the point of view of qualification of applied pyrotechnical tool and of programming of the planned effect. We will describe the results of development by introduction of experiments of parameters according to a new measurement procedure and by comparative analysis of them.
