Published: October 2018

A design of industrial control system is a complex process which is usually divided into specific design steps. Results from antecedent step are generally inputs for the next step and there could be also other influences among steps. So there is a strong dataflow within an automation project especially if the range of designed system is large from the point of view of the signals count, components, variables, alarms and other messages etc. The ability of effective and reliable data transfer between the steps has significant influence on effectivity and quality of the design of an industrial control system. The main goal of the paper is an analysis of the design steps during the industrial control system design, definition of the dataflows between particular steps and description of a concept of automated system for data transmission within the design. The proposed concept is presented and evaluated on pilot industrial control system design project.
The regenerated noise of HVAC elements and its measurement in pipeline track
Authors: Drabek Pavel
Published: October 2018

HVAC systems may spread unwanted noise that needs to be reduced. One of the components of wide range noise can be a regenerated noise which is a secondary sound source usually caused by air flowing through a device. This regenerated noise associated with airflow is indeed a dynamic function of velocity. Therefore, HVAC designers try to prevent these problems by sizing ductwork or duct configurations so that air velocity is low. Nevertheless, in certain situations, this approach is not possible and it is necessary to deal with the regenerated noise further. This article discusses an alternative way of measuring regenerated noise of various duct elements in the pipeline track without being connected to a reverberation chamber. It should be emphasized that this method is not new but information about it is very limited and therefore almost unused.

Published: October 2018

Demand for affordable and sustainable energy is growing. Even though the technology of construction and insulation of buildings is continuously improving, heating is still a significant issue for large part of Europe. Building modern heating systems as well as upgrading existing ones requires incorporating new technology and smart control systems with sophisticated control algorithms. An essential part of the control systems are models that allow the simulation to verify proposed actions or use series of simulation experiments to find the optimal solution. Several simulation tools are specializing in the field of energy already, and some general tools can also be used. This article shows two methods of own prediction mechanism of the heat demand of individual consumers (buildings). Modelling of individual buildings is the basis of the simulation model of district heating which is being developed. The fundamental idea is to build a modular model for specific district heating and start from the endpoints - from the individual consumption objects that will be interconnected through the distribution model with other parts of district heating system such as other consumers and producers. It is assumed that the heat demand is the most challenging part of the prediction, and therefore the accuracy and quality of these models will be the most significant to the accuracy of the entire future result.

Published: October 2018

Embedded systems are subjecting to various kinds of security threats. Some malicious attacks exploit valid code gadgets to launch destructive actions or to reveal critical details. Some previous memory encryption strategies aiming at this issue suffer from unacceptable performance overhead and resource consumption. This paper proposes a hardware based confidentiality protection method to secure the code and data stored and transferred in embedded systems. This method takes advantage of the I/D-cache structure to reduce the frequency of the cryptographic encryption and decryption processing. We implement the AES engine with composite field arithmetic to reduce the cost of hardware implementation. The proposed architecture is implemented on EP2C70 FPGA chip with OpenRisc 1200 based SoC. The experiment results show that the AES engine is required to work only in the case of I/D-cache miss and the hardware implementation overhead can save 53.24% and 13.39% for the AES engine and SoC respectively.

The security system (SS) model was proposed and its basic elements characterized to maintain the current security level of the information resources. The desired current security feature of the SIO shall be obtained by generating appropriate security technical and organizational configurations from the set of permissible solutions. The proposed concept, which takes into account the impact of not only basic security elements of the information resources (e.g. types of resources, security attributes, risks, vulnerability), but also changes in the working conditions of the information system and security system as well as the entire security and quality management environment of the organization, constitutes own proposal of the authors.
Game Semantics in Teaching of Classical First Order Predicate Logic to Stu- dents of Computer Science
Authors: Glivická Jana
Published: October 2018

Game-theoretical interpretation of logical semantics has been first suggested in 1950s. Although it is well know among professionals, it is often excluded from introductory courses in logic. In this paper we examine whether and to what extent would including game semantics in the syllabus of an introductory course of predicate and propositional logic prove to be beneficial to students’ understanding of the subject. To that purpose, we have exposed two groups of undergraduate students of computer science to game semantics as part of recitations for the course Propositional and Predicate Logic. We focus mainly on how this affects students’ mastery of two particular topics – alternating quantification and restricted quantification. Observations were made during the recitations to evaluate any changes in students’ approach to solving relevant problems in classroom. Moreover, before the final test of the recitations one of the groups was given a brief review of game semantics and the other was not. We have measured the difference in performance of these two groups and the results support the hypothesis that game semantics helps students master certain topics of predicate logic. We reference some of the later research in psychology and pedagogy to help us explain this effect.
Method for assessing efficiency of the information security management system
Authors: Kiedrowicz Maciej , Stanik Jerzy
Published: October 2018

The article addresses the issue of efficiency assessment of the security system (SS) in terms of the Information Security Management System (information resources of the information system in an organization). It is assumed that the purpose of such security system is to achieve a declared level of protection of the information system resources. Therefore, the level of security of information system in a given organization shall be determined by the efficiency assessment of the security system. The efficiency of the security system mainly depends on the functional properties of its components and other factors occurring in its environment. The article mainly focuses on security configuration, i.e. technical configuration and security organization configuration. The thesis was adopted that the efficiency of the security system may be considered as a set-theoretic efficiency sum of the security configurations invoked in such system. Additionally, it was assumed that a prerequisite for the desired measures (indicators) of the efficiency assessment of the SS shall be to propose such measures and develop appropriate ways (methods) of their calculation. The efficiency measure for the SS as well as two methods of efficiency assessment of the SS were proposed in the article.

A novel parallel algorithm for 3D modelling electromagnetic purification of water
Authors: Kudryashova’ Tatiana , Polyakov Sergey , Tarasov Nikita
Published: October 2018

The computational fluid dynamic research in this work has focused on the problem of full-scale three-dimensional modelling water purification processes by the electromagnetic method. Presently, this method of purification was used in the final stage of processing for the production of ultrapure water. In spite of many field experiments, detailed data on such processes can be obtained only by the mathematical modelling. This way allows us to take into account many aspects, for example: real three-dimensional geometry, physical structure of the purification system, heterogeneous composition of the impurities, etc. And also, the mathematical modelling helps to optimize many parameters in order to improve a design of the purification system. Within the framework of the modelling problem, one of the important aspects is the correct description of the three-dimensional flow inside a specific purification system. For this purpose, various mathematical models and numerical approaches are implemented. In this paper, the flow calculation was realized on basis of the Navier-Stokes equations.

Published: October 2018

This paper presents a multi-sensor decentralized fusion unbiased finite impulse response (UFIR) filter for discrete time-invariant state-space models. Fusion is provided in the minimum variance sense. By calculating the cross covariance between any of two local filters for the extended state-space model, linear optimal weights are derived to fuse local UFIR estimates. Simulation conduced for a two-state polynomial model shows that the proposed fusion UFIR filter has higher robustness than the fusion Kalman filter against errors in the noise statistics and temporary model uncertainties.
Time-domain aliasing and anti-aliasing effects in differentiating a band-unlimited signal
Authors: Shtrauss Vairis
Published: October 2018

In this paper, we investigate time-domain errors occurring in the two extreme discrete-time differentiation modes of band-unlimited signals: in the full-band processing mode and in the processing mode with ideal anti-aliasing filtering (AAF) with a cut-off at the Nyquist frequency. We disclosed that regardless sampling frequency the error from AAF is greater than the aliasing error. It is found that type IV differentiators designed by three commonly known digital filter design methods approximately equally process the high frequency portion of the signal above the Nyquist frequency with nearly equal aliasing errors having a weak dependence on differentiator length. In contrast, the differentiators very differently compute the derivatives of the low frequency portion bellow the Nyquist frequency providing rather dissimilar the common differentiation accuracy. The results show that the differentiators derived by using maximal linearity constraints are more accurate than those designed by the Parks-McClellan algorithm and the impulse response truncation method.

Ziel der Studie Um ein Online-Portal zur Vorbereitung auf die stationäre psychosomatische Rehabilitation zu entwickeln, wurden Informationsbedarf und Online-Nutzungsverhalten von Rehabilitanden untersucht.

Methodik Vier Fokusgruppen mit Rehabilitanden (N=31) sowie zwei mit Behandlern (N=18) wurden durchgeführt und qualitativ-inhaltsanalytisch ausgewertet.

Ergebnisse Insgesamt wurden 419 Aussagen von Rehabilitanden und 333 Aussagen von Behandlern kodiert und kategorisiert. Aktuelle Informationsmaterialien zur Rehabilitation wurden von Rehabilitanden als zu ausführlich und schwer verständlich eingeschätzt. Unsicherheit bestand vor allem hinsichtlich der Wirksamkeit und Nachhaltigkeit der Behandlung. Rehabilitanden und Behandler unterschieden sich dahingehend, dass die Behandler von Kurerwartungen ihrer Rehabilitanden ausgingen, während diese eher von einer aktiven Bewältigungsorientierung berichteten.

Schlussfolgerung Online-Portale zur Vorbereitung sollten durch anschauliche Fallbeispiele insbesondere auf die Wirksamkeit und Nachhaltigkeit der psychosomatischen Rehabilitation eingehen.
Sicherheit erfahren, ohne den Halt zu verlieren

Der Transfer aus dem Inkubator stellt Pflegende wie auch das Frühgeborene vor eine große Aufgabe. Das Kind verlässt die haltgebende Unterstützungsfläche und wird
durch den Raum getragen, es muss sich im ungewohnten Feld der Schwerkraft mit seinem ganzen Körper organisieren. Die gewohnte Schwerelosigkeit des Fruchtwassers
ist nicht mehr da. Der sichere, den ganzen Körper umfassende Halt, den es durch die Gebärmutterwände erfahren hat, existiert nicht mehr. Die Pflegende verfolgt
das Ziel, dem Kind Sicherheit und Geborgenheit zu vermitteln, um Stress und Schmerzen zu vermeiden.

Ethische Fragestellungen nehmen in der pflegeberuflichen Praxis einen großen Raum ein. Durch zunehmende medizinische und technische Möglichkeiten kommt es zum
Beispiel auch zu mehr Konflikten im Kontext der lebensverlängernden Maßnahmen. Damit einher geht die Frage nach Verantwortung zum Umgang mit ethischen
Konfliktsituationen bzw. beim Aufkommen ethischer Fragen. Werden diese nicht gelöst, führen sie zu massiven Belastungen – sowohl in der pflegeberuflichen Praxis
als auch im multiprofessionellen Team. Eine Möglichkeit des strukturierten Umgangs mit ethischen Konfliktsituationen bzw. Fragen und damit eine Unterstützung
für alle Beteiligten ist die Inanspruchnahme einer Ethikberatung, die beispielsweise mittels einer ethischen Fallbesprechung durchgeführt werden kann.

La tuberculosis genitourinaria es la segunda forma de presentación más común de tuberculosis extrapulmonar luego del compromiso ganglionar, la epididimitis tuberculosa afecta preferentemente a pacientes con edades comprendidas entre los 30 y 50 años, y al menos un 70% tienen historia previa de tuberculosis pulmonar, la infección tuberculosa del escroto es rara y ocurre en aproximadamente el 7% de los pacientes con tuberculosis por extensión directa desde el epidídimo, planteando problemas de diagnóstico diferencial con procesos más agresivos como las neoplasias testiculares. Reportamos el caso de un hombre de 23 años con masa testicular que emulaba ser de origen neoplásico, llevado a orquidectomía unilateral. La patología describe necrosis y granulomas de caseificación conclusivo para orquiepididimitis tuberculosa, paciente inmunocompetente sin antecedente previo de tuberculosis.

Aims and Objectives: Viability and health of the pulpal tissue after an exposure can be stimulated with biocompatible pulp capping materials. Mineral trioxide aggregate(MTA), though biocompatible with excellent sealing ability, has clinical disadvantages like poor handling properties and long setting time. New pulp capping agents- Biodentine and Theracal have proven to overcome MTA’s shortcomings. This study aimed to comparatively evaluate the sealing ability of Mineral Trioxide Aggregate(Angelus), Biodentine (Septodont) and Theracal(Bisco) when used as pulp capping agents. Materials and Methods: Occlusal cavities were prepared in extracted human third molars. The cavities were divided into 3 groups containing 12 samples each. Pulp capping in samples of group I, II and III was done with MTA, Biodentine and Theracal respectively. All samples were kept in a damp environment for 24 hrs. In each tooth, the root was cut just below the cementum-enamel junction. An aqueous 0.25% solution of Rhodamine-B was put in the open pulp chambers of all the samples and placed upside-down in a damp environment. The dye was left for 3 hrs to permeate toward the interface. After being stained, all samples were rinsed with distilled water and sectioned vertically. A Confocal Laser Scanning Microscope was used to image the samples. Results: No significant difference was found in interfacial microleakage between MTA and Biodentine. Theracal exhibited less interfacial microleakage than the two. Conclusion: Biodentine and MTA exhibit an efficient and durable protection of pulp. Theracal exhibits better sealing ability as a pulp capping agent than MTA and Biodentine.

Introduction: This study was conducted to evaluate clinical and radiographic findings induced by revascularization with and without platelet-rich plasma (PRP). Methods: Twenty patients with nonvital, immature anterior teeth were randomly categorized into 2 groups. Subsequent to minimal instrumentation of the root canal, disinfection was achieved with ledermix paste and followed by revascularization with and without PRP in groups 1 and 2, respectively. The cases were followed up clinically and radiographically at 6- and 12-month intervals. Results: Clinically, all cases were asymptomatic with complete resolution of signs and symptoms (except four cases which were considered as dropout). Radiographically, there was no significant difference in periapical healing, apical closure, and dentinal wall thickening in group I in comparison with group II. However, root lengthening was comparable for both of the procedures. Conclusions: Revascularization is a conservative and an effective method for inducing maturogenesis in nonvital, immature teeth. Supplementations with PRP can potentially improve the desired biological outcome of this regenerative procedure.
