Modelling of Stator Coil–To–Ground Faults in Induction Motor
Authors: Stanislav Kocman  , Pavel Pečínka
Published: September 2021

Three–phase squirrel cage induction motors are the most widespread types of electrical motors which can be found in both industrial and tertiary applications. There are some reasons why they are so often used, such as simple construction, nearly maintenance-free, advantageous price and the possibility to feed them directly from the AC network. Even if their reliability is very high, some unexpected breakdowns can occur during their operation. In this paper, coil–to–ground faults of motor stator winding have been taken into consideration. These failures have been modelled in several points of one stator phase using COMSOL software. As seen from simulation results these failures have a significant impact on current distribution in stator phases causing changes in rotor currents, motor inner torque, speed, etc., depending strongly on the actual point of the failure.

Published: September 2021

Currently, in the literature, there are no general guidelines for the optimal hydraulic design of Archimedean screw turbines (AST) used in hydrokinetic applications. Therefore, this study is aiming at selecting the most significant geometric factors, such as the diameter ratio between the inner (???????? ) and the outer (????????) diameters (i.e., ????????/????????), the axle length (????) and the blade stride (????), influencing the AST performance by using a central composite face-centered (CCF) experimental design combined with the response surface methodology (RSM). The statistical analysis of variance (ANOVA) test identified with a significance level of 0.05 that the most significant variables on the performance of the turbine were ???? and ????????/????????. The AST efficiency was evaluated by means of the power coefficient (????????), which was calculated by means of computational fluid dynamics (CFD) methods coupled with the 6-degrees of freedom (6-DoF) approach. The second-order polynomial model was used to predict the ???????? and the coefficient of determination (???? 2 ) was found to be 97.4%.

Nowadays, wind turbine fault detection strategies aresettled as a meaningful pipeline to achieve required levels of effi-ciency, availability, and reliability, considering there is an increasinginstallation of this kind of machinery, both in onshore and offshoreconfiguration. In this work, it has been applied a strategy that makesuse of SCADA data with an increased sampling rate. The employedwind turbine in this study is based on an advanced benchmark,established by the National Renewable Energy Laboratory (NREL)of USA. Different types of faults on several actuators and sensed bycertain installed sensors have been studied. The proposed strategy isbased on a normality model by means of an autoencoder. As of this,faulty data are used for testing from which prediction errors werecomputed to detect if those raise a fault alert according to a definedmetric which establishes a threshold on which a wind turbine workssecurely. The obtained results determine that the proposed strategyis successful since the model detects the considered three types offaults. Finally, even when prediction errors are small, the model isable to detect the faults without problems.

Published: September 2021

Instantaneous power theory has a central role in power systems analysis. Among mathematical settings used for the development of this theory, quaternion algebra has been used for describing electrical variables in recent works. In this context, this paper aims to describe three-phase power in a quaternion framework. We analyze quaternion power for balanced and unbalanced delta loads, comparing the expressions obtained to the usual expressions of complex power. The quaternion power expression obtained also makes it natural to introduce a decomposition of the unbalanced load in terms of a balanced component and an unbalanced load with null average power. It is also shown that delta unbalanced loads are equivalent to time-varying balanced loads. The results obtained extend the power systems theory in the quaternion domain and emphasize the advantages of using this framework.
Impact of harmonic distortion on the supraharmonic emission of pulse-width modulated single-phase power electronic devices
Authors: E. Kaufhold  , J. Meyer  , P. Schegner
Published: September 2021

This study demonstrates the frequency coupling in pulse width modulated (PWM) single-phase converters and inverters. As current state of the art, the harmonic frequency range, e.g. from fundamental frequency up to 2 kHz,is typically assessed separately from the so-called supraharmonic frequency range, i.e. above 2 kHz up to 150kHz. The frequency coupling between theharmonic and supraharmonic frequency range has not been thoroughly studied and is currently often neglected in the design process as well as for the analysisof the emission of power electronic devices.
The aim of this study is to analyse the behaviour of the frequency coupling between the harmonic and the supraharmonic range. In addition, laboratory measurements ofa commercially available single-phase inverter forphotovoltaic applicationsare shown to verify the findings.

Published: September 2021

This paper proposes a fast and accurate optimal sizing design of 1.5 MW Permanent Magnets Synchronous Generator (PMSG) for a grid-connected wind application. A design strategy inspired from the output space mapping technique is adopted. A fast analytical model is used and detailed to determine the parameters and the performances of the PMSG. Then, the results are validated by a precise finite element model and adjusted iteratively until coherence between the two models is obtained. A multi-objective particle swarm optimization algorithm is deployed with aim of reducing the total losses and weight of the generator. The algorithm's parameters and results are given and analyzed. Three optimal machines are chosen and tested using a 2D-finite element model. The main design parameters of the optimal generators are given and discussed. Good efficiency and optimal designs are obtained for the sized machines thanks to the adopted design strategy.

Vector control strategy of the 5-Phase 2-Level VSI
Authors: Jan Iwaszkiewicz  , Adam Muc
Published: September 2021

The paper describes an example of the vector control strategy applied to five-phase two-level inverters. Two base methods are discussed. The first one is based on the standard space vector transformation, while the other uses state vectors which enable the definition of the basic physical quantities of the inverter. The proposed notation system offers an universal simplification of vector identification. It comprises a standardized proposal of notation and vector marking. This tool may be really useful for the description of inverter states and makes it possible to reach correlation between state and space vectors. All vectors are defined by use of the same digits. The proposed mathematical tool has been verified during simulation tests performed with the use of the PLECS program.

This study presents the effect of political and social globalisation on Foreign Direct Investment (FDI) inflow in developing countries. The eminence of decomposed globalisation element in the FDI area is argued here. New insights into empirical evidence are offered by dropping economic globalisation as one of the decomposed components. A panel data of 42 developing countries from 1984 until 2016 was used by applying the CSARDL approach. The study is also on the impact of political and social globalisation in developing countries by splitting them into two income stratification: Upper Middle-income Countries and Lower Middle-Income Countries by incorporating financial development as a moderating variable. It documents that political globalisation postulates a U-shaped relationship after addressing the Cross-Sectional Dependence (CD) problem, while social globalisation reverses the U-shaped relationship. It was found that political globalisation and social globalisation are conditional to the level of income rather than the overall developing countries’ stream. Besides, the prominent role of financial development in promoting FDI inflow, especially to income level, was observed. We suggest that developing countries should increase the capacity to absorb political and social globalisation in promoting FDI.

The diversity of a board provides good information for decision-making. In addition, having individuals from different backgrounds and having unique knowledge sets, experiences and skills lead to better governance. The objective of this study was to investigate trends of diversity in the boardroom in publicly listed Malaysian companies. The study was conducted on a sample of 337 companies listed on Bursa Malaysia with 674 observations from 2015 & 2016. The findings show that the diversity of boards with respect to gender, age, education, and ethnicity is beneficial. Most corporations prefer to appoint men to the board of directors. The results of the study show that when it comes to age and ethnicity, diversity becomes a priority for companies to compete in the open market. In addition, the findings indicate that knowledge, which is related to education and qualifications, is a very important element for sitting in the boardroom. In addition, education, diversity has a positive significance in a family firm. Family members need to be better qualified to ensure that the company is able to survive in the market for longer periods. Keywords: board diversity, family firm, education diversity, age diversity

Authors:   Dire Dawa University, Ethiopia, Tesega Mekuanent
Published: September 2021

Foreign direct investment (FDI) is an important source of external financing and an important factor for the economic development of a country. FDI is highly important especially for developing countries as it brings modern technologies and management skills in addition to narrowing the financial gaps. In this sense the knowledge of what determines FDI will have a tremendous significance. With the objective of empirically determining the long-run and short-run relationships between financial development, trade openness and FDI inflows in Ethiopia this study employed the ARDL model. The findings indicated that private sector credit, M2 and trade openness have a positive and significant influence on FDI inflows in the long-run while M2, and trade openness has a positive and significant influence on FDI in the short-run too. Current period private sector credit had no impact on FDI while the one period lag of it has a positive significant effect on FDI. Likewise, the causality test results disclose the presence of bi-directional causal relationships between private sector credit and FDI, and between M2 and trade openness. Furthermore, the findings indicate a one direction Granger cause from M2 to FDI. Policy makers are advised to consider trade openness and financial development measures in their quest for more FDI inflow. Keywords: FDI, trade openness, financial development, ARDL, Ethiopia

Cryptocurrency (CCY) as a new key player in the currency system that has drawn the attention of scholars to examine its influence, relations and the opportunities that it may provide. However, a financial theoretical framework to connect CCY with financial theory is missing. This paper fills this gap by providing a review for the theoretical framework introduced in the literature to position CCY in investment and finance theories. This is done by studying the CCY literature and providing a critical feedback on the overall contributions in the area and possible venues for improvement. We report a need for a long-term analysis for CCY as this asset class is fairly new and sufficient data may not be available. Moreover, a better connection and linking with finance theories is required as it is significantly deficient. The promising potential of blockchain/ CCY stresses the need for interdisciplinary research including business, legal and information technology disciplines. In addition, the Covid-19 pandemic opens the door for further research to investigate the role of CCY as a hedge in the times of crises.

In the face of difficulties of teaching and learning due to the impact of Covid-19, online lessons have become vital. This has also affected the teaching of Mandarin as a foreign language at universities. Since Mandarin is considered as a difficult language to learn especially to non-native learners, teaching online has posted an even greater challenge to Mandarin language instructors. This study thus examines the use of a combination of platforms and applications online, customised to create an online learning system called ‘Pocket Mandarin’ to facilitate online Mandarin learning at the beginner level. The purpose is primarily to enable learning to take place in a fun and interactive manner by means of online flashcards, pronunciation, games and quizzes placed in an LMS platform called Padlet. To better understand how ‘Pocket Mandarin’ can effectively facilitate online teaching and learning among EFL basic learners at the tertiary level, a survey method was applied and it consisted of 5 parts which are students’ motivation, students’ attitude, cognitive development, design and interface as well as expectations. The results show that ‘Pocket Mandarin’ was positively accepted by the students who found the lessons motivating, upbuilding, cognitively applicable, with exceptional design and interface and was better than their initial expectations. Thus, there is great potential for the ‘Pocket Mandarin’ to be widely used at a greater scale.

The necessity of a proper physical training of athletes and their harmonious development of also implies making them accustomed with the practice of circuit training within handball specific training sessions. This ensures the mastery of a complex set of exercises and its methods of execution. Aims: We started from the premise that the chaining of several handball specific exercises within a training circuit can be beneficial for the development of conditional and coordinative abilities of the male U17 handball players. Methods: The method used was mainly the experimental one, speed testing in different directions was performed, with emphasis on execution, acceleration and force speed, as well as agility and general coordination. Data interpretation was performed by applying the statistical-mathematical method, the method of graphical representations. Results: The results show a statistically significant difference between mean results obtained by the subjects of the two groups in the "Training circuit 1" test for testing speed in different directions, with emphasis on execution, acceleration and force speed, as well as agility and general coordination, the average being 31.98 sec. for the experiment group and 34.48 sec. for the control group. As a result, the average of the experiment group is lower by 2.51 sec. (7.27%). Conclusions: The higher the motor skill indicators, the more the technical-tactical abilities of male U17 handball players will make the difference in achieving maximum efficiency.
El país como ningún otro: un análisis empírico del regionalismo yucateco

Se presume que los habitantes del estado de Yucatán tienen una identidad local propia, construida a través de los años por diferentes factores y que ha sobrevivido al afán integrador del nacionalismo mexicano. Sin embargo, a pesar de lo mucho que se ha escrito sobre tal identidad subnacional, ni se ha probado empíricamente ni se han especificado los componentes que la forjan. Este artículo pretende llenar el espacio existente identificando cuatro componentes de la identidad yucateca (regionalismo, etnocentrismo, internacionalismo, conservadurismo) para después, por medio de encuestas, examinar de forma empírica las bases demográficas de tres de los componentes señalados anteriormente. Finalmente, se analiza si hay un cambio generacional en los niveles de la identidad yucateca entre cohortes jóvenes y viejas motivados por la globalización económica y cultural.

This paper presents a hybrid computational model  based on regression techniques, machine learning and  physicomathematical algorithms developed for assistance in locating victims in the Brumadinho tragedy in 2019. The physicomathematical model, which provided results to help search teams, is based on integral and vector calculus, and fluid mechanics concepts. In addition, from data provided by the physicomathematical algorithm, two hybrid model were developed. One of them uses regression statistical and the  other one uses support vector regression which is a type of machine learning. With good prospects of the advances in research, it is  expected in future work, a more accurate model that can be used in other possible situations of dam-break. Moreover the model can be applied to situations involving computational fluid dynamics in general

Introduction

Previous cardiovascular disease (CVD) and myocardial involvement are common in coronavirus disease-19 (COVID-19). We investigated relationships between CVD, cardiac biomarkers and outcome in COVID-19.

Methods

We analyzed n = 252 patients from a multicenter study and provided comparison according to the presence or absence of underlying CVD. Cardiac biomarkers high-sensitivity Troponin [upper reference of normality (URN) 35 pg/ml for Troponin I and 14 pg/ml for Troponin T] and natriuretic peptides (Nt-pro-B-type natriuretic peptide, URN 300 pg/ml and B-type natriuretic peptide, URN 100 pg/ml) were both available in n = 136.

Results

Mean age was 69 ± 16 years (56% men, 31% with previous CVD). Raised hs-Troponin and natriuretic peptides were detected in 36 and 50% of the cases respectively. Age, chronic obstructive pulmonary disease, hemoglobin, hs-Troponin and natriuretic peptides were independently associated with underlying CVD (P < 0.05 for all). Compared with the normal biomarkers subgroups, patients with isolated hs-Troponin elevation had higher in-hospital mortality (31 vs. 4%, P < 0.05), similar CVD prevalence (15 vs. 11%) and trend towards higher D-dimer (930 vs. 397 ng/ml, P = 0.140). Patients with both biomarkers elevated had higher age, D-dimer, CVD and in-hospital mortality prevalence compared with other subgroups (all P < 0.05 for trend). Outcome analysis revealed previous CVD [model 1: OR 2.72 (95% CI 1.14–6.49), P = 0.024. model 2: OR 2.65 (95% CI 1.05–6.71), P = 0.039], hs-Troponin (log10) [OR 2.61 (95% CI 1.21–5.66), P = 0.015] and natriuretic peptides (log10) [OR 5.84 (95%CI 2.43–14), P < 0.001] to be independently associated with in-hospital mortality.

Conclusion

In our population, previous CVD was part of a vulnerable phenotype including older age, comorbidities, increased cardiac biomarkers and worse prognosis. Patients with isolated increase in hs-Troponin suffered higher mortality rates despite low prevalence of CVD, possibly explained by higher COVID-19-related systemic involvement.
Pandemic as an impulse for the development of sustainable tourism along the Danube river

Published: September 2021

The coronavirus (COVID-19) pandemic is a challenge to the world – primarily from the medical and economic point of view – but also to the search for new forms of tourism and the urban environment. Prior to mass vaccination, the main strategy to manage a pandemic were non-pharmaceutical interventions. Global travel restrictions and "home" regulations have caused the most serious disruption to the global economy since World War II. International travel bans affecting more than 90% of the world's population, widespread restrictions on public gatherings and community mobility have severely curtailed tourism since March 2020. Evidence of impacts on air transport, shipping and accommodation has been devastating. World tourism fell by 35-90% in 2020 compared to 2019. Yet, there are differences between countries. Tourism is particularly sensitive to measures against pandemics due to limited mobility and social distances. The paper compares the effects of COVID-19 with previous epidemics, pandemics or other types of global crises. It examines how a pandemic can change the society, economy, tourism and its projection into the territory. It discusses why COVID-19 is analogous to the ongoing climate crisis and why the mass growth tourism model needs to be questioned. The method to improve responsible access to our planet and ensure safe recreation for its population is sustainable tourism. The Danube Region has a great potential for the development of sustainable tourism in Slovakia with its transport accessibility, connection to the Danube River and through it to the surrounding areas. However, the potential of the region lies mainly in its hitherto underused cultural and natural conditions, as well as in the exploitation of the abilities of its inhabitants. The presented study analyzes the mentioned conditions and points out the possibilities of their development.

The accumulation potency of zinc nanoparticles in Nile tilapia (Oreochromis niloticus) was previously studied but their impacts on proximate chemical composition in muscle tissue by describing the dose-dependent accumulation and the protective role of vitamins (E + C), have not been investigated. Therefore, this study was carried out to assess the protective role of vitamins (E + C) on Zn accumulation in muscle and gill tissues of O. niloticus exposed to three sub-lethal concentrations (1/8 LC50, 1/4 LC50, and 1/2 LC50) of zinc oxide nanoparticles (ZnO NPs) compared to zinc oxide bulk particles (ZnO BPs) as well as their effects on the induced chemical composition alterations for different experimental periods (7, 14, 21, and 28 days). The data displayed that fish exposed to the different sub-lethal concentrations of ZnO NPs or ZnO BPs have a significant increase (P<0.05) in Zn ions accumulation in muscle and gill tissues compared to control group but Zn was accumulated in gill tissue higher than muscle tissue at all exposure periods. Also, Zn accumulation was higher in fish tissues exposed to ZnO NPs than ZnO BPs. On the other hand, groups supplemented with vitamins (E + C) showed a significant decreasing (P<0.05) in accumulated Zn levels compared to groups without supplementation. The values of these supplemented groups returned to similar levels established in the control at low concentrations but still higher than control at the high concentrations. Furthermore, the results showed that moisture and ash content slightly increased while protein and fat decreased in fish exposed to ZnO NPs or ZnO BPs compared to control group. In conclusion, the findings supported that a combination of vitamins (E + C) reduced Zn accumulation and ameliorated chemical composition alterations in O. niloticus fish.
