The problem of distributivity for different classes of aggregation operators is a topic that is currently being investigated by a significant number of researchers. The main issue of this paper is the characterization of all pairs of aggregation operators (G, H) where G is a semi-t-operator which is left or right distributive over semi-nullnorm H. The presented results also contain some previous research concerning distributivity of semi-t-operators over semi-nullnorm as the special case.

The paper present a novel approach using quaternions to model the error of a coordinate measuring machine. The intermediate angular error (pitch, roll and yaw) are calculated using quaternions. The positional error are interpolated using techniques from computer aide geometric design. The intermediate translational and angular errors are combined into homogeneous transformation matrices used for correcting the measurement errors.

Humanoid robots are the most illustrative representatives of complex cyber-physical systems. They are high-dimensional and highly coupled non-linear systems. Moreover, walking humanoid robots are underactuated with friction-limited unilateral contacts with the ground. These facts justify the need for hard real-time control of a robot's motion. Even the smallest delay in calculating the reference motion or setting the output control variable can lead to a catastrophic outcome. For this reason, most of the existing robotic control systems are real-time and custom made, intended for a specific robot (or family of robots). There is no platform offering a general tool to design the model of versatile configurations of robots and to use it in the model-based control algorithms in hard real-time. In this paper, a software tool for modelling of an articulated system consisting of several open branched kinematic chains for a hard real-time OS is proposed. The model of the robot can possess an arbitrary number of links. The software is developed on top of the QNX Neutrino real-time operating system, thus providing the precise execution of time-critical events. In the experiment, the advantages of using the general model by modelling one real robotic configuration with multiple branched kinematic chains will be shown. The processing performance during the on-line motion planning will be tested on a real-time platform running on ARM Cortex-A8 processor. The results will be compared with similar software running in a non-real-time simulation environment.

This paper raises the question about the worth of digital content and online curriculum from the point of students. It examines whether or not they have different attitudes towards the use of printed and digital materials. The research presented in this paper was conducted by electronic survey in May-June 2016 and was based on simple random sampling; the target group involved full time and part time students studying pedagogy, economics or engineering. The research focused on students' attitudes towards digital content and online curriculum, in order to determine how effective is the learning when the previous incorporated into learning process. We got N=105 analyzable answers within the deadline. The survey consisted of 16 closed questions.

This paper puts in the focus two important segments of information and communication technology. The first segment is monitoring of data centers and the second one is usage of open source hardware. The reason for combining these two segments is effort to explore the efficiency of open source hardware platforms in these environments. The advantages of open source hardware platform as a tool for rapid prototype development and combination of variety of technologies were taken as the main starting point for this research. This paper describes the model for data center temperature monitoring with the usage of open source hardware. The prototype system is partially implemented in accordance with the presented model.

Recently, the concept of energy harvesting has started to be considered and utilized in a variety of applications. The energy of the ambient has been exploited, employing different harvesting techniques, in order to provide the inexhaustible supply for the range of electronic devices. Concerning the energy stored in the electromagnetic field, among the known and prominent harvesting approaches, the inductance assemblies have been recognized for their simplicity, reliability and easiness in the production of various forms. This paper presents the simulation framework for the inductive sensor analysis, using the partial inductance approach for performance examination. The simple, planar, rectangular geometry is analyzed, regarding the potential increase of the overall sensor's inductance. The obtained results demonstrate fine agreement with previously reported findings.

An aim of the paper is to present a simple algorithm for creating a heaven-and-hell-origami-like object (H&H OLO) as a possible model for reconfigurable, self-folding, origami robot. It is an original, by happy chance resulting side-product of a research of synographs on an elliptic curve basis. The whole object has an analytical representation with the help of the explicit equations of the object components as well as through the simple linear transformations. Designing and creating robots, cyber-physical systems (CPSs) and others are potential branches of the next use, development and feedback inspiration.

Emerging as the most debated topic in IT these days, cloud computing services have become a business challenge for many enterprises. Different factors play the role of influence in the organizations on whether to adopt cloud computing services or not. The aim of this research is to investigate the current implementation strategies and adoption of Cloud computing services in Turkey. When cloud computing is adopted strategically, the changes are seen throughout the organization, therefore also changing the business aspect. This research also examines how strategy, people, processes, the already used technology and the organizational structure play a role in this transformation.

Navigation has always been important to people. Thus, it is hard to succeed in navigation without Global Positioning System. Although, Global Positioning System can be efficiently used in outdoor environments the indoor navigation is still in its infancy. Nevertheless, the indoor navigation is one of many open challenges in the 21st century that affects to the major technological advances. However, several indoor positioning solutions have been built over the last decade, but they are still neither accurate enough nor inexpensive for consumer use. Therefore, this paper proposes a novel suggestion that should have a great potential for applying mesh technology in the indoor navigation systems in order to improve the accuracy and the computational capabilities of devices.
