One of the most important numerical characteristics of dynamical systems used in control theory are the Bohl exponents. By contrast with the Lyapunov characteristics, the properties of the Bohl exponents are much less investigated in the literature. In this paper, we show the example of two-dimensional discrete time-varying linear system with bounded coefficients for which the number of upper Bohl exponents of solutions may be greater than dimension of the system.

Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a mine in order to be isolated from background seismic vibrations on the surface. This allows us to achieve a good sensitivity at low frequencies and high stability of the detector. Bare-bones equipment for the interferometer operation has been installed and the first test run was accomplished in March and April of 2016 with a rather simple configuration. The initial configuration of KAGRA is named iKAGRA. In this paper, we summarize the construction of KAGRA, including the study of the advantages and challenges of building an underground detector and the operation of the iKAGRA interferometer together with the geophysics interferometer that has been constructed in the same tunnel.

Modern, based on biomedical signals interfaces have become recently very complex, however the complexity does not always lead to increased functionality or usability. In particular, when it comes to handicapped users, the currently available solutions are far from satisfactory. In this paper an innovative approach for biomedical signals based interfaced with the implementation of an inexpensive gaming headset Emotiv EPOC was presented. The main goal was to design, and develop an intuitive and user-friendly interface based on implementation of various biomedical signals such as EEG or EMG. The project was primarily intended for handicapped users as a replacement for traditional interfaces such as keyboard or mouse, however its potential use was extended. The proposed system differs from the already existing interfaces mainly because of its versatility to work with various biomedical signals, thus enabling a single interface to be controlled with different devices. Initial investigation has proven that Emotiv EPOC headset could be applied as an inexpensive, easily available on the open market tool for Human-computer Interaction (HCI) systems for the gaming purpose.

We examine online sociality in Quora, a collaborative Q&A platform, through statistical analysis of 248 answers. Quora members interact through technology and with technology, creating different regimes of sociality: a regime of visibility, in which users and technology assemble the ranked list of answers;a regime of recognition, in which members rely on answers and authors' identity to acknowledge value;a regime of interaction, in which members comment on posted answers. We classify answers in three clusters: Sympa, Inspire and Casual. Answer types are related to the socio-technical creation of sociality regimes. © 2014 AISTI.

RETRACTED ARTICLE: Potential of support vector regression for solar radiation prediction in Nigeria

Natural Hazards 2015年第2期77卷 1055-1068页

作者： Olatomiwa, Lanre Mekhilef, Saad Shamshirband, Shahaboddin Petkovic, Dalibor Power Electronics and Renewable Energy Research Laboratory (PEARL) Department of Electrical Engineering Faculty of Engineering University of Malaya Kuala Lumpur Malaysia Department of Electrical and Electronic Engineering Federal University of Technology Minna Nigeria Department of Computer System and Technology Faculty of Computer Science and Information Technology University of Malaya Kuala Lumpur Malaysia Department for Mechatronics and Control Faculty of Mechanical Engineering University of Niš Nis Serbia

In this paper, the accuracy of soft computing technique in solar radiation prediction based on series of measured meteorological data (monthly mean sunshine duration, monthly mean maximum and minimum temperature) taking from Iseyin meteorological station in Nigeria was examined. The process, which simulates the solar radiation with support vector regression (SVR), was constructed. The inputs were monthly mean maximum temperature (Tmax), monthly mean minimum temperature (Tmin) and monthly mean sunshine duration ( $$ \bar{n} $$ ). Polynomial and radial basis functions (RBF) are applied as the SVR kernel function to estimate solar radiation. According to the results, a greater improvement in estimation accuracy can be achieved through the SVR with polynomial basis function compared to RBF. The SVR coefficient of determination R 2 with the polynomial function was 0.7395 and with the radial basis function, the R 2 was 0.5877.

On the Bohl and general exponents of the discrete time-varying linear system

引用

AIP Conference Proceedings 2014年第1期1637卷 744-749页

作者： Michał Niezabitowski Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Automatic Control 16 Akademicka Street 44-101 Gliwice Poland

Many properties of dynamical systems may be characterized by certain numbers called characteristic exponents. The most important are: Lyapunov, Bohl and general exponents. In this paper we investigate relations between certain subtypes of the general exponents of discrete time-varying linear systems, namely the senior lower and the junior upper once. The main contribution of the paper is to construct an example of a system with the senior lower exponent strictly smaller than the junior upper general exponents.

作者： Jerzy Klamka Michał Niezabitowski Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Automatic Control 16 Akademicka Street 44-101 Gliwice Poland

In this paper, finite-dimensional dynamical control system described by semilinear differential state equation with multiple variable delays in control are considered. The concept of controllability we extend on trajectory controllability for systems with multiple point delays in control. Moreover, remarks and comments on the relationships between different concepts of controllability are presented. Finally, simple numerical example, which illustrates theoretical considerations is also given. The possible extensions are also proposed.

Reiteration of Hankel singular value decomposition for modeling of complex-valued signal

AIP Conference Proceedings 2016年第1期1738卷

作者： Michał Staniszewski Agnieszka Skorupa Łukasz Boguszewicz Magdalena Wicher Marek Konopka Maria Sokół Andrzej Polański aSilesian University of Technology Faculty of Automatic Control Electronics and Computer Science Institute of Informatics Akademicka 16 Gliwice Poland bMaria Skłodowska-Curie Memorial Cancer Center and Institute of Oncology Gliwice Branch Department of Medical Physics ul.

Modeling signal which forms complex values is a common scientific problem, which is present in many applications, i.e. in medical signals, computer graphics and vision. One of the possible solution is utilization of Hankel Singular Value Decomposition. In the first step complex-valued signal is arranged in a special form called Hankel matrix, which is in the next step decomposed in operation of Singular Value Decomposition. Obtained matrices can be then reformulated in order to get parameters describing system. Basic method can be applied for fitting whole signal but it fails in modeling each particular component of signal. Modification of basic HSVD method, which relies on reiteration and is used for main components, and application of prior knowledge solves presented problem.

faculty of automatic control, electronics and computer science (AEC), Silesian University of Technology, Poland, is widely recognised as one of the leading polish Higher Education Institution (HEI) units. Recently, the institutional accreditation by the main national accreditation board - Polish Accreditation Council [1,2] - confirmed the highest teaching standards at the faculty. A significant part of assessment was based on the faculty Quality of Education Assurance System (FQEAS) performance. In the paper the faculty development strategy and structure of FQEAS will be presented. The assessment criteria will be discussed and the role of quality assurance system will be indicated. Future work with respect to teaching quality improvement, as well as FQEAS development, will be described. The properties of the presented FQEAS can be easily adopted in other national higher education systems.
