It is our pleasure to present the Proceedings of the International Conference on Information and Digital Technologies (IDT 2016), which was held in Rzeszów, Poland from 5th to 7th July 2016. The Conference IDT 2016was supported by the Polish Section of IEEE (in particular, the Polish Chapter of IEEE Computational Intelligence Society) and European Safety and Reliability Association (ESRA). The local...
This work investigates data compression algorithms for applications in non-volatile flash memories. The main goal of the data compression is to minimize the amount of user data such that the redundancy of the error correction coding can be increased and the reliability of the error correction can be improved. A compression algorithm is proposed that combines a modified move-to-front algorithm with...
One of the crutical issues to get competitive excellence for companies is perfect supply chain performance. The aim of this paper accents on the necessity of the supply chain management and develops a common performance measurements to evaluate the unique nature of the supply chain process. This paper provide models for a better supply chains effectiveness by designing robust and reliable supply chain...
Subsystem of heat supply is one of three subsystems constituting heat supply system together with subsystem of heat production and subsystem of heat distribution. An analysis of failures in the heat supply subsystem has been presented in the article. The analysis of variety, frequency and causes of failures, for individual kinds of district heating network: main ones, distributional ones and heat...
Despite serious and widespread efforts to improve the quality of health care, many patients still suffer preventable harm every day. Hospitals find improvement difficult to sustain, and they suffer “project fatigue” because so many problems need attention. No hospitals or health systems have achieved consistent excellence throughout their institutions. High-reliability science is the study of organizations...
This article describes the development of control system of robotic complex for constructions and buildings printing. Based on analysis of existing approaches authors propose the solution for control system development for 3D-printer with gantry-type construction, which can move on rails. Fully functional model of the control system was created by authors. It includes graph in the form of Petri net...
In the paper an approach to the reliability analysis of multistate systems and their redundancy is presented. First, basic notions concerned with reliability analysis of the ageing multistate systems are introduced. The system risk function and the moment of the system exceeding the critical reliability state are defined. The multistate series system with hot single reserve of its components is analyzed...
In the paper the basic notions of the ageing multistate systems reliability analysis are introduced. The system multistate components and the multistate system reliability functions are defined and the mean values of the multistate system lifetimes in the reliability state subsets and in the particular reliability states are determined. The notions of the multistate system risk function and the moment...
This study proceeds from the database of two patient groups. Patients in first group underwent intraabdominal anastomotic operation technique and they come from a selected hospital in USA. Patients in second group underwent extraabdominal anastomotic operation technique and they come from the Clinic of Surgery at the University Hospital Ostrava (Czech Republic). Both groups have more than 200 patients...
This paper presents the results of numerical and experimental investigation of thermal convection near heat emitting surfaces of an electric device. For the intensification of thermal convection, special vertical channels were formed near the heat emitting surfaces of the device. An experimental test has proved that there is an optimal length of the channels - thermal convection is the most intensive...
In high voltage power cable systems a problem of induced sheath voltages exist. Due to these voltages electric shock and damage of non-metallic outer sheath of the cables may occur. Exposure to voltage of the outer sheath may be very high in case of earth fault with high value of earth current. In order to reduce induced sheath voltages an earth continuity conductor (conductors) along power cables...
The paper deals with a method of reducing the unbalanced magnetic pull for large synchronous hydro generators, in case of rotor eccentricity and/or shape deviation of the rotor and stator. The method is based on a dedicated data acquisition system and virtual instruments developed in LabVIEW environment. Experimental results are presented for a 186 MVA and 500 RPM vertical synchronous hydro generator...
This paper describes the role of NI software and hardware in the implementation of actual learning technologies and the applying of a unified educational platform NI ELVIS II and NI LabView software for active learning technologies in the cognition of professional cycle disciplines.
The IEEE 802.tin standard networks are very popular nowadays. Such networks can use different throughputs and also different frame lengths, when aggregation is used. The fairness estimation seems to be very important tool for wireless network administrator to improve communication conditions in the network In this paper, the authors present results of the fairness calculation, when the time of media...
