    Opis:
    Foil bearings are a variety of slide bearings, in which an extra compliant foil set is applied between journal and bush, in order to improve the selected static and dynamic properties. Bearings of this type are investigated by engineers and researchers from all over the world since many years - both from simulation as well as experimental point of view. Due to the complexity of construction, the reliable simulation models are still being searched for. This paper discusses the most important stages of elaboration of the structural supporting layer of the foil bearing as well as results of verification tests. The main goal of the conducted study was assessment of reliability of the elaborated numerical model, in order to ensure that in future it could play a role of a reliable research tool, which could be used for elaboration of the numerical model of the entire foil bearing.

    Opis:
    Glass is used as an emerging structural member in the civil engineering construction industry. Fear and unconsciousness are the main hindrance to apply glass structure practically. Some safety glasses with the elastic interlayer material have the ability to carry higher loads than steel. So, it is high time to adopt this as a major load carrying structural member. At the beginning of this inspection elaborately presents the manufacturing process, basic properties and classification of glass for structural use. Reviewed portion of this work includes the recent research on the basic components of glass structure such as glass beam, glass column, glass slab or pavilion, glass walkway, glass panel, glass façade, curtain wall and glass frame under static or dynamic performances. The specific connection between glass with other materials and special types of different glass related composite structures like glass-concrete, glass-timber, glass-steel and glass-fiber are discussed. Special features of dynamic responses like effect of blast loading, wind born debris attack or cyclic loading and fire hazards of glass structure are also attached. Design guidelines and some practical applications are included to create interest, attention and courage for both structural engineer and architect. In recent years, a large number of glass related sophisticated developments have occurred in Europe. Since, An attempt has been taken to find out the huge research gaps in this sector so that this could fill in the future in order to spread glass design industry all over the world.

    Opis:
    The paper presents the results of the experimental static axial crush performance of unfilled and filled composite tubes. Composites are widely used as materials for energy absorbing structures because of their low density and a very high absorbed energy in relation to the mass ratio. Foamed materials are used in order to additionally increase their efficiency, because of stabilizing the progressive crush. It was proved by many authors that various foamed materials positively influence the energy absorption. In this work authors took effort to evaluate a very different material as a filler of common composite elements . elastomers. Elastomers are materials characterised by very high crush strains and viscoelastic properties. The tube shaped specimens made of epoxy composite, reinforced with carbon or glass fabrics were filled with elastomers of 40; 60; 70 and 90. ShA hardnesses. The influence of the elastomer hardness and the filling degree on the energy absorption factor (EA) was evaluated. The degree of filling the specimens with elastomers is determined by a different size of the elastomer perforation. Elastomers have a negative impact on the energy absorbed by the composite tubes.

    Opis:
    The use and the combination of new, high efficient materials for crashworthiness is of great interest nowadays. Foamed materials are commonly used to increase efficiency of composite materials. Based on the results obtained by Brachos and Douglas, it can be concluded that the sum of the energy absorption capabilities of the foamed filling and unfilled composite tubes is smaller than the energy absorbed by the tubes filled with the same filling. The paper presents the results of the experimental investigations into the influence of filling the tubes with different materials on the impact energy absorption capability. The tube shaped specimens made of epoxy composite, reinforced with carbon or glass fabrics were filled with foamed aluminium or foamed poly(vinyl chloride). It was proved that the foamed materials increase the energy absorption and the absorbed energy of the tubes filled with foams is greater than the sum of the energy absorbed by the composite tube without filling and the foamed material itself investigated separately, when the wall thickness is more than 2 mm. The investigations of the filled tubes with the thickness of walls equal to 1 mm showed lower absorbed energy values because the crushing force had decreased during the crush. The investigations were executed to show what are the effects of filling composite energy absorbing elements in the shape of tubes with foamed materials. Additionally, influence of tube wall thickness and crush mechanism were studied.

    Opis:
    To further optimise the bullet-proof performance of textile reinforced composites, multi-directional friction tests of aramid and ultrahigh molecular weight polyethylene (UHMWPE) yarns were carried out by the slope method. The influence of the included angle between the high-performance yarns on the static friction coefficient for aramid and UHMWPE yarns was studied by measuring the friction coefficient. The relationship between the static friction coefficient and the included angle among the high-performance yarns was discussed. The results showed that the friction coefficient of aramid yarns was higher than that of UHMWPE yarns. Especially, at the same included angle between high-performance yarns, the static frictional coefficient of aramid yarns is 50% higher than that of UHMWPE yarns. In accordance with expectations, the static friction coefficient decreases with the increased included angle between high-performance yarns, and the included angle of high-performance yarns changes from 0º to 90º. The trend of rapid decline appeared when the included angle between high-performance yarns changed from 0º to 15º. For the actual result, the static friction coefficient of aramid and UHMWPE yarns is less than 0.3, which needs to be improved to increase the bullet-proof performance of textile composites.

    Opis:
    Fault diagnosis and condition monitoring of synchronous machines running under load is a key determinant of their lifespan and performance. Faults such as broken rotor bars, bent shafts and bearing issues lead to eccentricity faults. These faults if not monitored may lead to repair, replacement and unforeseen loss of income. Researchers who attempted to investigate this kind of machine stopped at characterizing and deduced ways, types and effects of rotor eccentricity fault on the machine inductances using the winding function method. A modified closed-form analytical model of an eccentric synchronus reluctance motor (SynRM) is developed here taking into cognizance the machine dimensions and winding distribution for the cases of a healthy and unhealthy SynRM. This paper reports the study the SynRM under static rotor eccentricity using the developed analytical model and firming up the model with finite element method (FEM) solutions. These methods are beneficial as they investigated and presented the influence of the degrees of static eccentricity on the machine performance indicators such as speed, torque and the stator current and assess the extent to which the machine performance will deteriorate when running with and without load. The results show that static eccentricity significantly affects the machine’s performance as the degree of eccentricity increases.

    Opis:
    Green high performance fiber reinforced cementitious composites (GHPFRCC) are a new class of sustainable cementitious composites, employing a high volume of fly ash to replace cement. In addition to increasing the sustainability of the construction environment, GHPFRCC exhibits a high tensile ductility and multiple cracking behaviors in the strainhardening state. These materials can effectively improve the structural energy dissipation capacity and structural durability. In this study, the optimum mixture ratio of GHPFRCC is presented established using an orthogonal experiment for a specific engineering application. The described GHPFRCC sustains the mechanical performance of concrete and is employed as the outer cladding to strengthen concrete columns. The finite element analysis of the material was based on the software ABAQUS and pseudo static experiments were conducted to exhibit retrofitting of GHPFRCC applied in the rehabilitation of seismic-damaged concrete columns. The computed and experimental results showed that GHPFRCC, while incorporating high volume fly ash, can retain significant multiple cracking behaviors. The energy dissipation capacity of the GHPFRCC reinforced concrete (RC) column is better than the comparable unreinforced column.

    The performance of buckling load of tubular structures under quasi-static axial loading is quite appreciable, numerous tubes of various cross-section have been extensively investigated and corrugated sections have been designed to further improve the performance. In this paper, a carefully designed set of key performance indicators (KPIs) is utilized to assess and compare the buckling load of circular and corrugated tubes. A series of diagrams related to KPIs with various parameters of tubes are presented to demonstrate the influence of sectional configuration on the performance of tubes as well as the effect of the material on the potential of the same. The work is inestimable to engineering designs and applications, and further studies on the buckling load of other configurations.

    Opis:
    The presented preliminary research concerns the accuracy and reliability of new ultra-fast static positioning module - POZGEO-2 - in case of processing GPS data collected outside the ASG-EUPOS network. Such a case requires extrapolation of the network-derived atmospheric corrections which limits correction accuracy and, therefore, has adverse effect on the carrier phase ambiguity resolution. The presented processing tests are based on processing 5-minute long observing sessions and show that precise positioning can be supported up to 35 km from the ASG-EUPOS borders. This means that precise positioning with POZGEO-2 module can be assured for the most of the border areas of Poland.
    W pracy prezentowane są badania dotyczące dokładności i wiarygodności pozycji wyznaczanej z wykorzystaniem nowego modułu ultra-szybkiego pozycjonowania - POZGEO-2 opracowanego dla systemu ASG-EUPOS. Przedstawione testy obliczeniowe dotyczą szczególnego przypadku wyznaczania pozycji, gdy użytkownik znajduje się poza granicami sieci stacji referencyjnych. W takich warunkach wymagana jest ekstrapolacja sieciowych poprawek atmosferycznych. Wpływa to negatywnie na dokładność tych poprawek i może doprowadzić do sytuacji, w której wyznaczenie nieoznaczoności będzie niemożliwe. Prezentowane badania oparte są na pięciominutowych sesjach obserwacyjnych i pokazują, że poprawki mogą być ekstrapolowane dla obszarów położonych do około 35 km od granic sieci ASG-EUPOS. Oznacza to, że w praktyce precyzyjne pozycjonowanie ultra-szybkie z użyciem modułu POZGEO-2 może być zapewnione dla niemal całego obszaru Polski.

    Opis:
    Bike-fitting methods based on knee kinematics have been proposed to determine optimal saddle height. The Holmes method recommends that knee angle be between 25° and 35° when the pedal is at bottom dead centre in static. Other authors advocate knee angle of 30–40° during maximum knee extension while pedalling. Although knee angle would be 5–10° greater at bottom dead centre during pedalling, no study has reported reference values in this condition. The purpose of this study was to compare these three methodologies on knee, hip, and ankle angles and to develop new dynamic reference range at bottom dead centre. Methods: Twenty-six cyclists volunteered for this experiment and performed a pedalling test on their personal road or mountain bike. Knee, hip, and ankle angles were assessed by two-dimensional video analysis. Results: Dynamic knee angle was 8° significantly greater than static knee angle when the pedal was at bottom dead centre. Moreover, dynamic knee angle with the pedal at bottom dead centre was 3° significantly greater than dynamic knee angle during maximum knee extension. The chosen methodology also significantly impacted hip and ankle angles under most conditions. Conclusions: The results allow us to suggest a new range of 33–43° when the pedal is at bottom dead centre during pedalling. Thus, this study defines clearly the different ranges to determine optimal saddle height in cycling according to the condition of measurement. These findings are important for researchers and bike-fitting professionals to avoid saddle height adjustment errors that can affect cyclists’ health and performance.

    Opis:
    Today, Parallel Kinematic Machines tools (PKMs) appear in automotive and aeronautic industries. These machines allow a benefit of productivity due to their higher kinematics performances than Serial Kinematic Machines tools (SKMs). However, their machining accuracy is lower. Moreover, the compensation of the defects which penalizes the machined parts quality is difficult due to their anisotropic behaviour. Thus, this article deals with the development of methods improving the machined parts quality and the productivity. In order to improve parts quality, the static behaviour of the machine structure is considered with a model taking into account joints and legs compliances. Then, it allows determining a static workspace. About the productivity, the improvement of kinematics performances is performed through an optimization work of the non productive tool path between cutting operations. The computed tool path must verify a minimum time constraint and avoid collisions between the tool and the machined part. All the methods are illustrated with the PKM Tripteor X7 developed by PCI.

    This study is driven by a motivation to examine the key determinants of bank’s performance as proxied by bank’s liquidity (LR), non-performing loans (NPL), capital adequacy ratio (CAR), loan growth (FEXP) and default risk premium (FQL) within the framework of credit creation theory of banking. Using random effect model as an estimation tool on 93 banks in Middle East, Africa and Indian subcontinent over study period from 2009 through 2016, the findings reveal that there are significant relationships between bank’s performance and its loan growth. Both ROA and FEXP are also found to be positively correlated. In contrast, the NPL and CAR are found to be negatively correlated with ROA. As a whole, it is evident that loan growth plays a very important role in supporting bank’s long term performance.
    Celem badania jest przeanalizowanie kluczowych czynników determinujących wyniki banku w zależności od jego płynności (LR), zagrożonych kredytów (NPL), współczynnika wypłacalności (CAR), wzrostu kredytów (FEXP) i premii za ryzyko niewypłacalności (FQL) w ramach teorii bankowej dotyczącej działalności kredytowej. Jako narzędzie oceny, w 93 bankach na Bliskim Wschodzie, w Afryce i na subkontynencie indyjskim, w okresie od 2009 r. do 2016 r. wykorzystano model efektu losowego. Wyniki pokazują, że istnieją istotne zależności między wydajnością banku a zwiększeniem aktywności kredytowej. Na podstawie przeprowadzonych badań stwierdzono, że zarówno ROA, jak i FEXP są skorelowane dodatnio, natomiast NPL i CAR są skorelowane ujemnie z ROA. Reasumując, należy stwierdzić, że zwiększenie aktywności kredytowej odgrywa bardzo ważną rolę we wspieraniu długoterminowej wydajności banku.
