Opis:
Acoustic measurements such as scale modeling measurements require a particular type of miniature omnidirectional sound source. The most important aspects of those devices are small sizes (usually below 100 mm in diameter) and different frequency ranges compared to traditional, omnidirectional sound sources used in room acoustics. The required frequency range differs regarding the used scale factor in different models, which leads to the troubles in frequent source changes and the need for a unique source design for every model. The project will present the recent achievement in miniature omnidirectional sound sources development. The optimal sound sources for the given measurement functions were developed based on the previous numerical simulations and experiments such as FEM sound directivity simulations or transducers' parameters tolerance testing. The sound sources presented are used for applications such as acoustic sound insulation scale measurements (frequency range 800 ÷ 63 000 Hz), scaled reverberation chamber measurements (300 ÷ 80 000 Hz), or acoustic reduction models measurements (400 ÷ 70 000 Hz). The paper will cover a detailed technical explanation of the laboratory environment's source construction aspects and validation measurements.

Opis:
Temporally and spatially unstable thermal conditions lead to inhomogeneous thermoelastic changes in the workpiece geometry. Consequently, non-negligible geometric deviations are evident, especially when measuring large workpieces with narrow tolerances, which often take place in non-climatized production environments and thus make thermal monitoring indispensable. Accurate determination of the thermoelastic behaviour for complex and large geometries is a challenging task with computationally effortful or less accurate existing solutions. Thus, the development of innovative measurement and modelling approaches is subject of current research, whereat physical validation is a prerequisite. Therefore, the authors developed a method, enabling the emulation of typical process heat cycles on a turbine housing in combination with a geometric measurement system. The idea is to provide reproducible and reversible thermal conditions on a representative large workpiece and to investigate the resulting geometric deformation in an economically viable way. Throughout this study, an analogy test rig is presented, integrating different temperature sensors, two geometric measurement systems and thermal deformation models into one demonstrator. The demonstrator's first applications show insightful results, revealing accordance, but also unexpected deviations between the predicted and measured quantities. Moreover, it provides great potential for validation of more complex modelling approaches and innovative thermal condition monitoring systems for large precision workpieces.

Opis:
Regulation models based on the human cognitive systems and ethics are embodied in social institutions. Among the issues of the processes of urbanization, secularization, anti-war speeches, the fight against poverty and discrimination, spirituality became an important subject of research especially in the Post-Soviet sociological space, where the common elements of the social development were widely represented in different kinds of research, but the impact of religion and spiritual activity was underappreciated and was almost not studied. Some of the approaches and terms were borrowed from the Western sociology, as well as the liberal approach of market economy was initially studied on the basis of materials copied from American and European textbooks. Very soon scholars discovered that the notion of spirituality had different connotations on the territory of the former Soviet republics, where the hunger for spirituality was inherited (Mariański 2009: 149-179) since the omnipresent and ubiquitous communist ideology concerned the social life, including the religious activity of the populations of the former Soviet Union regions. Spirituality also began to awaken interest of social science as the knowledge of the organization of social life. Since the USSR collapse, the concepts of, spirituality as well as new spirituality become an important novelty for the sociological science, sociological reviews and conferences. At the same time, spirituality started to be used as an argument in the political and economic discussions that provoked the critics of this concept among scholars as well as inspired scepticism in society. The presented paper deals with the cognitive approach and combines the sociological approach with analysis of spirituality and the economic analysis of the intellectual systems and computing machines, especially, the “cognitive” processes of machine learning with the use of software for human beings to determine the requirements for the regulation mechanisms of the behavior human beings and machines in the digital era.

Opis:
Reliable estimation of coal and rock mechanical properties at field scale is a prerequisite for numerical modelling of rock behaviours associated with longwall extraction. This paper describes a systematic approach from data collection, laboratory testing to rock mass properties derivation for simulation of longwall extraction, taking two longwall panels at Quang Ninh coalfield in Vietnam for example. The mechanical properties are verified through comparison with published data of the field, indicating close agreements. A simple numerical model is further developed to demonstrate the proper use of the obtained data. The simulation suggests that the ratio of model length to excavation length should be in the range of 2.5–5; uniaxial compressive strength, deformation modulus and tensile strength can be reduced by a factor of 5.0, 2.13 and 2.0, respectively; and a calibration and validation process must be performed to match in-situ longwall’s behaviours. The approach can be applied for derivation of reliable rock mass properties for numerical simulation of underground excavations.
Rzetelne oszacowanie właściwości mechanicznych węgla i skał w skali polowej jest warunkiem koniecznym do numerycznego modelowania zachowań skał związanych z eksploatacją ścianową. W artykule, opisano systematyczne podejście od gromadzenia danych, badań laboratoryjnych do wyznaczania właściwości górotworu w celu symulacji eksploatacji ścian, na przykład na dwóch panelach ścianowych na polu węglowym Quang Ninh w Wietnamie. Właściwości mechaniczne są weryfikowane poprzez porównanie z opublikowanymi danymi polowymi, wskazując na bliskie uzgodnienia. Dalej rozwijany jest prosty model numeryczny w celu zademonstrowania właściwego wykorzystania uzyskanych danych. Symulacja sugeruje, że stosunek długości modelu do długości wykopu powinien zawierać się w przedziale 2,5–5; jednoosiową wytrzymałość na ściskanie, moduł odkształcenia i wytrzymałość na rozciąganie można zmniejszyć odpowiednio o współczynnik 5,0, 2,13 i 2,0; oraz należy przeprowadzić proces kalibracji i walidacji, aby dopasować zachowanie ściany na miejscu. Podejście to można zastosować do wyprowadzenia wiarygodnych właściwości górotworu do numerycznej symulacji podziemnych wyrobisk.

Opis:
Physical scale models have a large range of application in studies of hydraulic works. In port engineering, they can be used to optimize the general layout of terminals, evaluation of protection structures, simulation of vessel maneuvers and investigation of mooring plans for vessels, among several subjects. Once physical modeling allows a high accuracy in the waves and currents representation as well as their interaction with the bottom and the vessels, the studies of mooring systems in coastal and estuarine ports based on physical modeling tests provide greater reliability in comparison with those grounded on distinct types of models. To highlight the importance of this kind of application, this article presents the case study of the Ponta da Madeira Port (PMP), located in the State of Maranhao, Brazil, developed with the support of the 1:170 scale reduced physical model conceived and calibrated for this area. This study analyzed several alternatives to improve the availability of the northern berth of the Pier III of PMP, including new mooring strategies and the construction of a new improvement structure. The results, which concerned on preliminary tests of the mooring lines tensions, evidenced structural intervention could substantially reduce the risk of mooring lines break, indicating that further investigations concerning different layouts for the improvement structure are promising in order to provide an increase of this berth availability.

Opis:
In the paper, the authors present an ongoing research on the absorption and measurement uncertainty of perforated panels made at different scales. Knowing the similarity criteria describing the relation between a full-size perforated panel and its scaled equivalent, it is possible to conduct the measurements of the elements of significantly reduced size - with an area not exceeding 0.2 m2. This procedure notably decreases the costs resulting from the production, transportation and storing the measurement samples. At the same time, the obtained values of sound absorption coefficient measured for the samples at 1:8 scale will characterize their full-size equivalents of geometry changed according to the derived similarity criteria. The paper discusses the possibilities of measurement of scaled samples.

Opis:
The objects of consideration are thin linearly elastic Kirchhoff-Love-type circular cylindrical shells having a periodically microheterogeneous structure in circumferential and axial directions (biperiodic shells). The aim of this contribution is to formulate and discuss a new averaged general asymptotic-tolerance model for the analysis of selected dynamic problems for the shells under consideration. This model is derived by applying the combined modelling which includes two techniques: the asymptotic modelling procedure and a certain extended version of the known tolerance non-asymptotic modelling technique based on a new notion of weakly slowly-varying function. Contrary to the starting exact shell equations with highly oscillating, non-continuous and periodic coefficients, governing equations of the averaged combined model have constant coefficients depending also on a cell size. The differences between the general combined model proposed here and the corresponding known standard combined model derived by means of the more restrictive concept of slowly-varying functions are discussed.

Opis:
Scale modelling should be a very useful strategy for the design of lunar structures. Preventing structural damages in the lunar environment is crucial and scale models are helpful to achieve this aim. The size of these models must be scaled to take into account the different gravitational levels. Since the lunar gravity acceleration is about one-sixth of the terrestrial one, it follows that the models on Earth will be very smaller than the prototype to be realized on the Moon. This strategy will represent an opportunity for engineers working on lunar structure design, provided that the errors, both computational and experimental, related to the change of scale are quantified, allowing reliable extension of the physical scale modeling results to the prototype. In this work, a three-dimensional finite element analysis of walls retaining lunar regolith backfill is described and discussed, in order to provide preliminary results, which can guide a future experimental investigation based on physical scale-modelling. In particular, computational errors related to the scale effects are assessed, with respect to a virtual prototype of the lunar geotechnical structure, and compared with errors from other sources of discrepancy, like the adopted constitutive model, the variability of the geotechnical parameters and the calculation section used in the 3D analysis. The results seem to suggest the soundness of this strategy of modelling and are likely to encourage new research, both numerical and experimental, supporting the structure serviceability assessment.

Real 3D experiments in small-scale need to be prepared in sense of exactness by exact calculations including mathematic πnon-dimensional groups in order to make a functional small-scale model representing the full scale modelling in the effective way. The interior represented by the cribs made mostly of wood, polymer and other materials common in rooms or offices need to be prepared in sense of their amount, position and porosity. After that the construction of the small-scale model can be started with respect to all the dimensions, amount and proportion of material calculations.

Opis:
The objects of consideration are thin linearly elastic Kirchhoff-Love-type circular cylindrical shells having a micro-periodic structure in circumferential direction (uniperiodic shells). At the same time the shells have constant structure in axial direction. The aim of this contribution is to formulate and discuss a new nonasymptotic averaged model for the analysis of selected dynamic problems for these shells. This, so-called, general tolerance model is derived by means of a certain extended version of the known tolerance modelling of micro-heterogeneous media. This version is based on a new notion of weakly slowly-varying functions. Contrary to the starting exact shell equations with highly oscillating, non-continuous and periodic coefficients, governing equations of the tolerance model have constant coefficients depending also on a period of inhomogeneity. Hence, the model makes it possible to investigate the effect of a cell size on the global shell dynamics (the length-scale effect). The differences between the general tolerance model proposed here and the corresponding known standard tolerance model derived by means of the more restrictive concept of slowly-varying functions are discussed.
Przedmiotem rozważań są cienkie liniowo-sprężyste powłoki walcowe typu Kirchhoffa- Love’a mające periodycznie mikro-niejednorodną strukturę w kierunku obwodowym. Powłoki takie nazywamy uniperiodycznymi. Celem pracy jest sformułowanie nowego, nieasymptotycznego, uśrednionego modelu służącego do analizy wybranych zagadnień dynamiki takich powłok. Przedstawiony ogólny model tolerancyjny wyprowadzony jest w oparciu o pewną zmodyfikowaną wersję znanej techniki tolerancyjnego modelowania struktur mikro-niejednorodnych. Wersja ta bazuje na nowym pojęciu funkcji słabo wolno-zmiennej. W przeciwieństwie do równań wyjściowych dla analizowanych powłok niejednorodnych mających współczynniki periodyczne, silnie oscylujące i nieciągłe, równania modelu tolerancyjnego mają stałe współczynniki. Ponadto, współczynniki te zależą od parametru długości mikrostruktury. Tym samym umożliwiają badanie efektu skali.

Opis:
The hydroacoustic signatures of ship propellers can be identified experimentally through measurements of cavitation-induced pressure fluctuations and the accompanying noise distribution at model scale. These measurements have to be performed in a cavitation tunnel at the propellers operating conditions and with sufficient accuracy. In comparison, the numerical approach can be used to present a good general idea of the predicted results. Numerical methods can provide highly accurate tools for noise level and propagation prediction, as well as giving insight into the flow field and other key aspects. They are also not influenced by signal conditioning or disturbance sources present in a physical environment. So we trade scope and precision of the results for time and cost reduction. In this paper, we described both experimental and numerical methods currently in use and present advantages and limitations of the practical application of both.

Abstract: In this paper the application of the Extended Finite Element Method (XFEM) to anticipate change of the behaviour of composite with complex internal structure after use of the admixtures was presented. The response to mechanical loadings of bent beams made of hydraulically bonded mixture with rubber admixture was considered. The impact of the rubber granulate on the value of fracture energy was analysed. Moreover, the influence of an interfacial transmission zone quality on the achieved effect was assessed. Calculations were conducted by means of the muli-scale numerical model which was built in ABAQUS finite element method environment. The results derived indicate beneficial effect of rubber granulate on fracture energy of hydraulically bonded mixture.

Opis:
This article presents and assesses 64 different ways for predicting the failure onset in knotty wooden beams. The aim is to provide engineers and modellers a generalview of how to evaluate the failure in wooden structural members with knots.The studied criteria included both the conventional point-based and average stress theories. Special attention was paid to the effect of the elements of the woodmesostructure, i.e. knots and fiber deviation, which can generate singular stress concentrations as notches or cracks would do in fracture mechanics. The case study consisted of predicting the failure onset of bending in structural wooden beams.A previously validated finite element model was used in order to compute the heterogeneous stresses. It was found that the knots caused considerable stress singularities so that the size of the average stress theory influenced the failure predictions by up to 23%. However, the variations generated by distinct phenomenologicalcriteria were in general much smaller. The application of the average stress theory in large stress integration volumes is strongly recommended when predicting the failure in wood members.

Opis:
There exist numerous models of software architecture (box models, ADL’s, UML, architectural decisions), architecture modelling frameworks (views, enterprise architecture frameworks) and even standards recommending practice for the architectural description. We show in this paper, that there is still a gap between these rather abstract frameworks/standards and existing architecture models. Frameworks and standards define what should be modelled rather than which models should be used and how these models are related to each other. We intend to prove that a less abstract modelling framework is needed for the effective modelling of large scale software intensive systems. It should provide a more precise guidance kinds of models to be employed and how they should relate to each other. The paper defines principles that can serve as base for an integrated model. Finally, structure of such a model has been proposed. It comprises three layers: the upper one – architectural policy – reflects corporate policy and strategies in architectural terms, the middle one –system organisation pattern – represents the core structural concepts and their rationale at a given level of scope, the lower one contains detailed architecture models. Architectural decisions play an important role here: they model the core architectural concepts explaining detailed models as well as organise the entire integrated model and the relations between its submodels.
