Opis:
A microstructural model of Red Blood Cell (RBC) behaviour was proposed. The erythrocyte is treated as a viscoelastic object, which is denoted by a network of virtual particles connected by elastic springs and dampers (Kelvin-Voigt model). The RBC is submerged in plasma modelled by lattice Boltzmann fluid. Fluid – structure interactions are taken into account. The simulations of RBC behaviour during flow in a microchannel and wall impact were performed. The results of RBC deformation during the flow are in good agreement with experimental data. The calculations of erythrocyte disaggregation from the capillary surface show the impact of RBC structure stiffness on the process.

Opis:
The aim of this research is to examine the relationships between authenticity, subjective happiness, and life satisfaction. The participants were 347 university students. In this study, the Authenticity Scale, the Subjective Happiness Scale, and Satisfaction with Life Scale were used. The relationships between authenticity, subjective happiness and life satisfaction were examined using correlation analysis and Structural Equation Model (SEM). In correlation analysis, authentic living was found positively related to subjective happiness. On the other hand, self-alienation, accepting external influence was found negatively correlated to subjective happiness. Besides subjective happiness and life satisfaction have positive relation. Structural Equation Model showed that self-alienation, accepting external influence results in a decrease subjective happiness on life satisfaction whereas rise in authentic living lead to subjective happiness, so subjective happiness also brings life satisfaction. According to standardized beta coefficients (β= -.49), the most significant predictor of subjective happiness was self-alienation. Results were discussed in the light of the related literature.

Opis:
Thailand hosts over 50 percent of the world’s top OEM automotive parts suppliers and additionally is home to over 2,400 Tier 1-3 manufacturers and suppliers. Given the significance of these numbers and Thailand’s leading ranking and contribution to the global automotive industry, research was undertaken to determine how manufacturing clusters and innovation capability effect competitive advantage as it relates to automotive production part management. Multiple objectives were established which included the study of the effects and overall influences of the various variables on competitive advantage as well as the development of a structural equation model (SEM) to define how innovation and manufacturing clustering affects the competitive advantage within the Thai automotive parts molding sector. Quantitative methods analysis was conducted on the data from 240 automotive production and components suppliers’ questionnaires collected from industry managers with the research results partially obtained from the analysis by use of (PLS)-graph. Qualitative research was also obtained by use of purposive sampling from in-depth interviews from ten senior managers. The results obtained indicated that clusters and innovation capability has a significant and positive effect on competitive advantage. Thus, the findings from the research illustrate that if an organization focuses on clusters, there will be a knock-on effect within the automotive parts groups leading to the increase in innovation capability, which creates a greater competitive advantage, not only for the enterprises, but also for Thai society as well.

Opis:
A structural equation model was used to verify both the direct and indirect influences on research and development and innovation capabilities that affect Thai automotive parts enterprises competitive advantage. Thailand’s automotive sector is a major driver of the economy with a multi-thousand network of both domestic and international companies contributing a significant amount to both domestic and Asian economic growth. After peaking in 2013 and reaching the Top 10 automotive nations, there has been a slide backwards. Competition is fierce and the pace of change ever quickening. Therefore, the researchers sought to determine how the automotive parts sector needed to improve in capability, skills and infrastructure to maintain a sustainable competitive advantage. From the structural equation model analysis of 220 regional automotive parts sector managers and use of AMOS software, it was determined that research and development combined with innovation plays key roles in the industry’s profitability and survivability. Additionally, there must be support across a wide sector of the economy, including universities, government agencies and institutions. Once championed as the ‘Detroit of Asia’, Thailand’s recognized success as a global automotive hub is a classic case of a well-executed industrial plan but that lead can potentially slip away without embracing new technologies and innovative thinking.

Opis:
Przedmiotem zainteresowania badaczy ilościowych są najczęściej zależności między pojedynczymi zmiennymi pomiarowymi. W niniejszym artykule zaprezentowano alternatywne podejście – modelowanie równań strukturalnych (SEM) techniką ważonych najmniejszych kwadratów ze skorygowaną średnią i wariancją (WLSMV). Umożliwia ono badanie zależności między bateriami zmiennych (konstruktami teoretycznymi), włączając zmienne kategorialne. Analizie poddano wyniki badania przeprowadzonego w 2015 roku, koncentrując się na określeniu determinant samodzielnego podejmowania decyzji w gospodarstwie domowym. Zbadano, jak stosunek emocjonalny do pracy zawodowej, pozycja tamże, siła charakteru, proaktywna postawa wobec otoczenia oraz waga wyglądu zewnętrznego wpływają na chęć samodzielnego podejmowania decyzji w gospodarstwie domowym. Analizę przeprowadzono również w podziale na dwa obszary decyzyjne: finansowy i pozafinansowy.
Relationships between separate variable are the common subject to quantitative researchers. In this article an alternative approach is demonstrated: structural equation modelling (SEM) by weighted least squares means and variance adjusted estimation (WLSMV), which makes possible to assess relationships between batteries of variables (theoretical constructs), including categorical ones. Analysis is based on the results of a research carried out in 2015 and the focus is put on determinants of unilateral decision-making in the household. The study examines the way factors, such as: mental attitude towards work, position at work, strength of character, open attitude towards others, importance of own appearance, affect willingness to making decisions in the household. Analysis is also performed for financial and non-financial decisive areas separately.

Opis:
The presence of a binary variable in the cointegrated VAR (CVAR) model is most often interpreted as the structural break affecting the data generating process. It is proved in the paper that to enjoy this interpretation the binary variable must appear simultaneously inside and outside the cointegration space. In order to test for the break we advocate to employ the Wald statistic, however, its critical values and the power had to be simulated separately for the possible change of the constant, the trend, and both. The experiments were designed for different sizes of the cointegrating space, number of variables, the span of the break, normally and t-distributed errors. It is shown that the power of the test depends mostly on the magnitude of the break and the sample size while other factors are of secondary importance. In order to test for the break at unknown period the supWald statistic was proposed.

Opis:
The main objective of this study was to develop a spatial temperature distribution of the Karkonosze Pluton to indicate optimum locations for HDR systems at drillable depth. HDR geothermal technology makes it possible to extract heat from the Earth in areas where no hydro-geothermal resources are present. To produce electricity in a binary cycle, system temperatures of > 100°C are usually required. In this paper, the authors have analysed the potential opportunities for applying HDR technology in the area of the Karkonosze Pluton, which is regarded as an optimum location for the application of the HDR concept (due to the potential for stimulation offered by the mechanical properties of the granites, radiogenic heat production, modern tectonic activity, and the thickness of the pluton). The model used in the analysis, which takes into account a hypothetical assessment of the manner and paths of fluid migration within the pluton, provides an insight into the spatial distribution of subsurface temperatures. It thus allows the location of relatively shallow high-temperature zones, which are optimal for the efficient application of HDR technology, to be identified. With respect to this technology, the Szklarska Poręba area and the NE part of the pluton seem to be better targets than the Cieplice central area, where the model indicated much lower temperatures (e.g. at a depth of 5,000 m, estimated temperatures in the vicinity of Szklarska Poręba were about 185°C and in the vicinity of Cieplice they were about 140°C).
Celem badań było opracowanie przestrzennego rozkładu temperatur plutonu Karkonoszy dla wskazania optymalnej lokalizacji dla systemu HDR na głębokościach osiągalnych wierceniami. Geotermalna technologia HDR umożliwia wykorzystanie ciepła wnętrza Ziemi na obszarach pozbawionych płynów termalnych głównie a aspekcie produkcji energii elektrycznej w systemach binarnych. Dla efektywnej pracy takich systemów wymagana jest temperatura górotworu powyżej 100°C. W artykule autorzy analizowali potencjalną możliwość zastosowania technologii HDR na obszarze plutonu Karkonoszy, który potraktowano jako optymalny dla zastosowania systemu HDR – głównie wskutek mechanicznej podatności granitów na procesy sztucznego szczelinowania, wysoką produkcję ciepła radiogenicznego, współczesną aktywność tektoniczną oraz znaczną miąższość plutonu. Prezentowany, hipotetyczny model strukturalno-termiczny uwzględniający sposób i drogi migrujących płynów pokazuje przestrzenny rozkład wgłębnych temperatur w obrębie plutonu. Umożliwia to lokalizację stref wysokich temperatur położonych względnie płytko, a zatem optymalnych dla efektywnego zastosowania technologii HDR. W tym kontekście, strefa plutonu w rejonie Szklarskiej Poręby oraz jego część NE przedstawiają się korzystniej niż strefa centralna w rejonie Cieplic, gdzie przeprowadzone modelowanie wskazuje temperatury znacznie niższe (np. w strefie Szklarskiej Poręby na głębokości 5000 m temperatury około 185°C natomiast w strefie Cieplic około 140°C).

Opis:
The present work focuses on the modeling and analysis of mechanical properties of structural steel. The effect of major alloying elements namely carbon, manganese and silicon has been investigated on mechanical properties of structural steel. Design of experiments is used to develop linear models for the responses namely Yield strength, Ultimate tensile strength and Elongation. The experiments have been conducted as per the full factorial design where all process variables are set at two levels. The main effect plots showed that the alloying elements Manganese and Silicon have positive contribution on Ultimate tensile strength and Yield strength. However, Carbon and Manganese showed more contribution as compared to Silicon. All three alloying elements are found to have negative contribution towards the response- Elongation. The present work is found to be useful to control the mechanical properties of structural steel by varying the major alloying elements. Minitab software has been used for statistical analysis. The linear regression models have been tested for the statistical adequacy by utilizing ANOVA and statistical significance test. Further, the prediction capability of the developed models is tested with the help of test cases. It is found that all linear regression models are found to be statistically adequate with good prediction capability. The work is useful to foundrymen to choose alloying elements composition to get desirable mechanical properties.

Opis:
This paper deals with a Structural Decomposition (SDA) applied to the analysis of the freight traffic demand in an Input Output (IO) modelling context. After reviewing the basic definitions of IO models and some methodological references for their application in the freight transport field, the paper proposes the application of the SDA in the perspective of a freight corridor. This application takes place downstream of an IO model that directly relates the quantities of goods transported along the corridor with the functioning of the reference economic system. Considering the evolution of tons annually trans-ported in a certain time interval, the SDA model allows to isolate the specific effects related to: intensity of freight traffic typical of the corridor; technological structure of the production sectors; characteristics of the final demand in relation to its overall level, sectoral structure and allocation between components. The SDA model is applied to a case study considering the total volumes of goods annually in transit at the Brenner pass between 2000 and 2014. The evaluation of the polar forms of the multiplicative decomposition and their geometric mean allow to quantify the effects of each factor on the variation of the tonnage in terms of indexed value, absolute variation and percentage contribution compared to the base year (2000). The relative influences on freight traffic at the Brenner pass are therefore highlighted, both in terms of total volumes transited and impacts attributable to each of the decomposition factors introduced, with particular evidence also in the event of periods of economic and financial crisis. The SDA specified in the paper and the related case study provide useful elements for studying the traffic demand of goods through a freight corridor, helping in outlining the effects of the different driving forces related to the economic system and affecting freight transport demand trends.

Opis:
The paper analyses the consequences of structural change in the presence of non-stationary stochastic processes I(1) or I(2). The structural change may concern the deterministic structure (in particular, the trend and the constant term) as well as the process generating the stochastic part. The focus of the paper is on the case of a discrete change in a regime for which the moment of switch is known. A change in the deterministic part does not alter the character of the cointegration relationships but its consequences for cotrending and cobreaking are interesting. The consequences of a change in the stochastic part are more complex, because then the stochastic process as well as the deterministic structure of the VECM are modified. The restrictions are analysed for both cases.

A strip yield model implementation by the present authors is applied to predict fatigue crack growth observed in structural steel specimens under various constant and variable amplitude loading conditions. Attention is paid to the model calibration using the constraint factors in view of the dependence of both the crack closure mechanism and the material stress-strain response on the load history. Prediction capabilities of the model are considered in the context of the incompatibility between the crack growth resistance for constant and variable amplitude loading.
Opracowany przez Autorów model pasmowego płynięcia został zastosowany do prognozowania rozwoju pęknięć zmęczeniowych obserwowanych w badaniach zmęczeniowych próbek ze stali konstrukcyjnych w warunkach obciążeń stało- i zmiennoamplitudowych. Skoncentrowano się głównie na kalibracji modelu przy użyciu odpowiednio dobranych współczynników skrępowania uwzględniających zarówno mechanizm zamykania się pęknięcia jak i naprężeniowo-odkształceniową charakterystykę materiału właściwą dla danej historii obciążenia. Wyniki prognoz przy użyciu tak skalibrowanego modelu zostały poddane gruntownej ocenie z uwzględnieniem różnic w rozwoju pęknięć obserwowanych w przypadku obciążeń stało- i zmiennoamplitudowych.

Opis:
The present paper addresses the analysis of structural vibration transmission in the presence of struc- tural joints. The problem is tackled from a numerical point of view, analyzing some scenarios by using finite element models. The numerical results obtained making use of this process are then compared with those evaluated using the EN 12354 standard vibration reduction index concept. It is shown that, even for the simplest cases, the behavior of a structural joint is complex and evidences the frequency dependence. Comparison with results obtained by empirical formulas reveals that those of the standards cannot accurately reproduce the expected behavior, and thus indicate that alternative complementary calculation procedures are required. A simple methodology to estimate the difference between numerical and standard predictions is here proposed allowing the calculation of an adaptation term that makes both approaches converge. This term was found to be solution-dependent, and thus should be evaluated for each structure.

Internal Model Control
Opis:
The active noise-reducing casing developed and promoted by the authors in recent publications have multiple advantages over other active noise control methods. When compared to classical solutions, it allows for obtaining global reduction of noise generated by a device enclosed in the casing. Moreover, the system does not require loudspeakers, and much smaller actuators attached to the casing walls are used instead. In turn, when compared to passive casings, the walls can be made thinner, lighter and with much better thermal transfer than sound-absorbing materials. For active noise control a feedforward structure is usually used. However, it requires an in-advance reference signal, which can be difficult to be acquired for some applications. Fortunately, usually the dominant noise components are due to rotational operations of the enclosed device parts, and thus they are tonal and multitonal. Therefore, it can be adequately predicted and the Internal Model Control structure can be used to benefit from algorithms well developed for feedforward systems. The authors have already tested that approach for a rigid casing, where interaction of the walls was significantly reduced. In this paper the idea is further explored and applied for a light-weight casing, more frequently met in practice, where each vibrating wall of the casing influences all the other walls. The system is verified in laboratory experiments.

Opis:
Many studies on middle income trap draw attention to the product trap that can be expressed as the fact that countries are stuck in the production and export of unsophisticated products. In this sense, it is stated that the role of a country in the production and export of sophisticated goods is one of the determinant factors to increase the level of income. In the literature, the concept of economic complexity, which is expressed as gaining competitiveness of complex products in terms of production and export, is noteworthy in recent years. In this framework, relationship between the per capita GDP and the economic complexity is examined with regression analysis in this study for selected countries with high-level of income. In the analysis, in which random coefficient panel regression model is applied, a significant relationship was found between the two variables for Austria, Finland, Hong Kong, Japan, Norway, Singapore and Sweden.
