Active flux based adaptive and non-adaptive observer for sensorless interior permanent magnet synchronous machine drive
Authors: Vyas Deepak , Morawiec Marcin , Ayana Tadele , Wogi Lelisa , Guzinski Jarosław
Published: September 2024

The use of the interior permanent magnet synchronous machine (IPMSM) drive has profoundly increased in a large number of applications due to numerous advantages. Owing to the disadvantages of mechanical sensors, sensorless control techniques are employed to enhance the performance of the IPMSM drive by removing the effect of noise and gain drift due to the sensor, increasing reliability, cost saving, and reducing overall size. This article presents the comparative analysis between the adaptive observer and non-adaptive extended electromotive force (EEMF) observer based on the active flux concept in a stationary reference frame (α–β). Moreover, the effect of slot harmonics and non-sinusoidal distribution of rotor flux is present in the three-phase IPMSM, this problem is considered as the control system disturbances in this article. Due to the non-sinusoidal distribution of flux and slot harmonics, the observer structure in the rotating reference frame (d–q) fails to estimate at the low-speed operation range. Comparative analysis between adaptive and non-adaptive observer structures is provided for a wide speed range. The effectiveness of the observer structures is examined using the classical field-oriented control scheme. In the end, simulation and experimental results are demonstrated to validate the performance of the sensorless control scheme using the adaptive and non-adaptive observer structures for the three-phase IPMSM drive setup.

Published: September 2024

Introduction

Perfusion index (PI) is used as assessment of epidural anaesthesia efficacy in human medicine, but its usefulness in dogs is unknown. The aim of this study was to evaluate the usefulness of PI in determining epidural anaesthesia effectiveness.

Material and Methods

This is prospective cross-over experimental study. Five healthy adult beagle dogs were anaesthetised and an epidural catheter was inserted in the lumbosacral area and adjusted so that the end of the catheter was placed at the fourth lumbar vertebra. Single-port catheters were used in the control group and multiple-port catheters were used in the treatment group. A PI probe was placed on a hind leg, and the catheter placement was confirmed via computed tomography. The treatment group received a bolus dose of lidocaine, and the control group received saline, via epidural catheter. The PI value was recorded every 5 min until 30 min after lidocaine injection.

Results

The PIs of the hind limbs were not significantly different over time, nor were they between the control and lidocaine-injected groups at any point in time.

Conclusion

The PI is not useful in determining the efficacy of epidural anaesthesia in dogs under general anaesthesia. In the future, finding a reliable method to evaluate the success of regional anaesthesia, even in patients under general anaesthesia, will be necessary.

Published: September 2024

Introduction

This study aimed to determine the bacterial diversity of chicken carcasses and their surrounding environment at various stages along a poultry slaughter line.

Material and Methods

Amplicon sequencing of the 16S rRNA gene was employed to assess the shifts in bacterial community diversity at both phylum and genus levels. Samples were collected from September to November 2021, targeting carcass surfaces at various operational stages (post-defeathering, post-evisceration, post-water chilling, and post-cooling), as well as from the internal environments and air of these units. The study took place in a vertically integrated poultry slaughterhouse in Konya, Turkey.

Results

Microbial diversity increased after the chilling and storage stages as a result of redistribution of the microorganisms after the physical effect of the slaughtering stages. The final product sample taken after storage had the highest bacterial abundance. The abundance at this stage was found to be strongly correlated with that at other slaughtering stages, as well as with the abundance in chilling water and on the personnel’s hands. The common genera in chicken carcasses during slaughter stages were Macrococcus, Acinetobacter, Enterococcus, Escherichia-Shigella, Psychrobacter, Streptococcus, Lactococcus and Ligilactobacillus. Microbiome data in environmental samples indicated that the genera in highest relative abundance were Bacillus, Anoxybacillus, Acinetobacter and Psychrobacter. In air samples, the storage room had the highest diversity and in this place Bacillus spp. and Staphylococcus spp. were in the majority.

Conclusion

This study may provide some useful information to pinpoint the critical contamination sources in the poultry slaughtering process.
Numerical Study on the Effect of Weight Variables on the Roll Damping Coefficients for a Fishing Vessel
Authors: Seo Janghoon , Park Dong-Woo
Published: September 2024

The roll damping coefficient is essential when considering the viscous effect in the potential-based hydrodynamic analysis of fishing vessels; it is an important factor in the roll motion response. The present study performs free roll decay simulations, altering weight variables using Computational Fluid Dynamics (CFD) to investigate the correlation between the roll damping coefficient and the weight variation of a fishing vessel. The time series of roll amplitude and roll damping coefficient are compared, for varying vertical and longitudinal centres of gravity and radii of gyration in roll motion. As the vertical centre of gravity increases, both the roll decay period and the roll damping coefficient also increase. The roll decay period tends to increase with the increase in the radius of gyration during roll motion, while the roll damping coefficient exhibits a decrease. A longitudinal centre of gravity has a limited effect on free roll decay characteristics. The roll damping coefficients between the maximum and minimum combinations of weight variables show significant differences. The findings of the present study could enhance the understanding of the safety of fishing vessels based on their loading conditions. Consequently, future research could further improve the results obtained in the present study by considering various hull shapes and speeds.
Determination of Propeller-Rudder-Hull Interaction Coefficients in Ship Manoeuvring Prediction
Authors: Kołodziej Radosław , Hoffmann Paweł
Published: September 2024

The assessment of ship manoeuvring properties is a crucial part of the process of ship design and is usually first carried out during the model test phase of the project. According to the International Maritime Organisation (IMO), the manoeuvrability of the ship can be assessed on the basis of the standard trial manoeuvres. In order to do this, free running model tests or captive model tests are used, in conjunction with a mathematical model of ship motion; this is considered to be a reliable prediction method. In recent years, numerical-based methods have also been widely used in ship hydrodynamics and constantly improving computing power and more accurate fluid dynamics models have made the simulation of more complex cases possible. The study presented in this paper focuses on the determination of propeller-rudder-hull interaction coefficients based on the Mathematical Modelling Group (MMG) standard method in ship manoeuvring prediction. The identification of the parameters uses both captive model tests and a simplified numerical method, as well as regression formulas. The results of 35° turning and 10°/10° zig-zag manoeuvres, obtained with the use of each prediction method, are then compared. The test case used in the study is the container type cargo ship equipped with a single propeller and rudder. The model scale, for which the referenced model tests were carried out, is equal to 1:25 and a NACA 0020 rudder profile was used. This research highlights the advantages and disadvantages of each presented prediction method and their potential for future improvement.
Increasing the Economic Efficiency of Marine Power Plants Using Waste Heat Boilers with Controlled Flow Separation
Authors: Kuznetsov Valerii , Kuznetsova Svitlana
Published: September 2024

Heat recovery of exhaust gases from main and auxiliary marine diesel engines is an effective way to improve the technical and economic parameters of marine power plants. Improvements in engine efficiency necessitate an increase in the weight-size parameters of the waste heat boilers, which makes it difficult to recover heat. Intensification of the heat transfer process is considered to be an effective way to reduce these indicators. By utilising mathematical modelling, this paper shows the effectiveness of using profiled heating surfaces of waste heat boilers for this purpose. The use of elliptical heating surfaces with a mechanism of controlled flow separation, in the form of a triangular notch, is proposed. This will reduce surface drag and increase the overall thermal-hydraulic efficiency of the heat transfer processes. It is shown that the use of such surfaces in waste heat boilers makes it possible to increase the efficiency of marine power plants in tankers with a deadweight of about 45,500 tons up to 1.5% absolute and container ships with a deadweight of about 122,000 tons up to 2.5% absolute.
Do Chairs Reduce a Navigator’s Mobility? Pilot Study on the Influence of Navigation Bridge Design on Lookout Routines
Authors: Stopa Michał
Published: September 2024

Despite technological progress in the maritime industry, navigators are still the final link of the decision-making chain and rely not only on equipment, but also on human senses. Visual observation of the vessel’s surroundings still plays a crucial role in navigation. Four different ships in service were visited to investigate the work of professional navigators and carry out a pilot experiment on real crews to test the methods for future full-scale research. The main objective was to better understand the influence of bridge design on lookout routines of navigators, while the additional goals were to check the presence of navigators in certain parts of the bridge and to determine if it is reasonable to forbid navigators to sit, as the practice is still used on some ships. Considering space limitations and differences in layouts of the wheelhouse, rarely mentioned in this kind of study, the movement of watch-keeping officers was analysed. In total, twenty observations were made to generate the heatmaps of presence during the routine duties. The results of the research indicate that many factors, including bridge design and layout of equipment, might affect lookout routines but it is possible to find similar patterns on the bridges of different shapes and arrangements. The pilot experiment confirms that it is reasonable to carry out a full-scale study, as there is still room for improvement in the area of ergonomic bridge design. Better understanding of modern lookout and movement routines might lead to the development of adequate ergonomic regulations and result in increased work comfort and the well-being of seafarers.

Authors: Drešček Marko , Miroševič Špela , Rifel Janez , Orešković Stjepan , Švab Igor , Homar Vesna
Published: September 2024

Introduction

Tobacco use is a major global health problem, contributing to premature death and disability. In Slovenia, the prevalence of smoking is higher than the EU average, emphasizing the need for effective tobacco control measures. The aim of this study was to identify the characteristics of patients most likely to benefit from pharmacotherapy for smoking cessation.

Methods

We performed cross-sectional analysis of factors associated with successful smoking cessation using pharmacotherapy for Slovenian smokers. A total of 176 (24.6%) smokers with an average age of 50 years agreed to receive pharmacotherapy for their smoking cessation attempt and were enrolled in the study. Participants were followed up at 4-week intervals during treatment and for 24 weeks after completion of pharmacotherapy.

Results

Attempts to quit smoking with prescription medications were successful in 24.4% of those willing to try. Female smokers, older persons, those with more children, with a lower self-perception of health, a higher number of cigarettes per day and a higher nicotine dependence were more likely to attempt to quit smoking. However, the strongest predictors of smoking cessation success were lower nicotine dependence, which was tested using the Fagerström test for nicotine dependence, and higher adherence to pharmacotherapy.

Conclusion

Nicotine dependence and adherence to pharmacotherapy are the strongest predictors of a successful smoking cessation attempt. Identification of potential responders, prescription of pharmacotherapy and follow-up are applicable in the primary healthcare setting.

Authors: Rotar Pavlič Danica , Maksuti Alem , Kopčavar Guček Nena , Albaradi Islam , Stepanović Aleksander
Published: September 2024

Background

The use of e-cigarettes has been rapidly expanding in recent years. The reasons people in Slovenia chose to use electronic cigarettes have not been studied to date. This study examines e-cigarette users' attitudes regarding their health risks.

Objectives

The aim of the study was to examine the users' standpoint towards e-cigarettes and their understanding of the impact on people's health.

Methods

This qualitative study consists of 15 semi-qualitative interviews. Fifteen active or former tobacco smokers and/or e-cigarette users were interviewed using semi-structured interviews between 1 December 2019 and 30 April 2020. Data were analysed using qualitative content analysis. The employed inductive analysis consisted of coding, creating categories and abstraction; that is, framing a general description of the research topic through generating categories.

Results

Data show that the interviewees do not have a unified opinion regarding the use and harmful effects of e-cigarettes. They agree that e-cigarettes are less harmful than regular cigarettes, but do not believe that they completely eliminate harmful effects for people that smoke regularly. The results also show that vaping is typical of young people, who use e-cigarettes as an important element of their subculture.

Conclusions

The use of e-cigarettes in Slovenia is still a matter of public debate, because the advantages and harmful effects of using e-cigarettes are not yet well known. National guidelines for reducing the harmful effects of e-cigarettes are needed.

Algebraic thinking ability are important for students to master and use algebraic concepts in various situations. Students with good algebraic thinking ability will find it easier to solve real-world problems and understand more abstract mathematical concepts. This study aims to describe students' algebraic thinking ability on linear equation material. Thus, the type of research used is phenomenology with a qualitative descriptive approach. The participants in this study consisted of 37 students; six students with heterogeneous abilities (high, medium, low) were then selected. The research subjects were determined by purposive sampling based on the pattern of answers representing the phenomenon that occurred. Data were collected using algebraic thinking ability tests and interviews to fulfill the validity of the data. The results showed that: 1) students with high algebraic thinking ability can use all indicators of algebraic thinking well. 2) students with medium algebraic thinking ability have difficulty in the indicators of analytical thinking, modeling, and dynamic thinking. 3) students with low algebraic thinking ability have difficulty in all indicators of algebraic thinking, namely generalization, modeling, abstraction, analytical thinking, dynamic thinking, and organization. So, teacher efforts are needed to provide students with an understanding of algebraic thinking so that students can solve math problems well.

KONSEP SALAMATUL FITRAH DALAM AL-QUR’AN (ANALISIS WACANA KRITIS DALAM SURAH YUSUF)
Authors: Said Rukman Abdul Rahman , Bakri Mubassyirah , Bakri Mubarak
Published: September 2024

This article discusses the concept of the salamatul fitrah (nobility or purity of fitrah) in Surah Yusuf. The nobility of fitrah refers to the natural condition of humans who are born with a tendency to seek truth, goodness and beauty. This article reviews how humans can maintain the nobility of their fitrah through taqwa and obedience to Allah. In Surah Yusuf, taqwa is shown by the Prophet Yusuf when he refused the offer of adultery from Potiphar's wife even though it could give her worldly benefits. This concept teaches that humans must always maintain the nobility of their fitrah and always try to get closer to Allah. In Surah Yusuf, the nobility of fitrah can be seen from the character of Prophet Yusuf who always seeks truth and justice in the face of various obstacles. He also showed firmness of faith and patience in the face of severe trials. Apart from that, the concept of nobility of fitrah can also be seen in the attitude of Potiphar (the Egyptian dignitary) who bought Yusuf, as well as in the story of the Prophet Yusuf's brothers who were faced with jealousy and envy which led them to bad actions. In conclusion, the concept of the nobility of fitrah in Surah Yusuf teaches people to always improve themselves and face various tests of life with firmness of faith and patience. It is hoped that this article can provide a deeper understanding of the concept of the nobility of fitrah and how humans can improve it through piety and obedience to Allah.

AbstractThis article discusses the various meanings of fasting or shaum in the Koran. This research departs from the difference in the meaning of shaum between QS. Maryam verse 26 and QS. Al-Baqarah verse 183. Through the analytical descriptive data analysis method with the semantic approach of the Koran, the author tries to analyze in an inclusive and comprehensive manner related to the variations in the meaning of fasting in the Koran. Linguistically, fasting means refraining from something or leaving it, be it refraining from eating, talking or walking. This meaning contained in QS. Maryam verse 26. However, functionally in the Koran, fasting does not only mean withholding, but also the part of worship that must be carried out with the provisions of the applicable Shari'a (QS. Al-Baqarah verses 183-185, 187), and also has an alternative meaning expiation or ransom for prohibited acts (QS. Q.S Al-Baqarah verse 196, Q.S An-Nisa verse 92, Q.S Al-Maidah verse 89).

The Aceh government has put Sharia into effect after receiving permission from the Indonesian government to enact Islamic law. The Aceh government took advantage of this chance to formally incorporate Islamic law into the nation's legal framework. This essay examines the development of Sharia and how it is used today. In this research, additional information in the shape of electronic information, rules, and government websites directly linked to the topics covered in this paper were used as data sources to learn more about Sharia in Aceh. This study incorporates various empirical studies carried out by earlier scholars in the form of papers, books, and other significant material to enhance the data and analysis. The findings of this study revealed that for more than 20 years, the application of Sharia had created a culture that was submissive to Islamic law, with the Acehnese Muslim community increasingly receiving instruction to uphold Sharia through the use of terminology from the "porch of Mecca". Communities that are not Muslim also help Aceh establish Sharia law. In addition to being founded on personal knowledge, adherence to Sharia is also made stronger by the legal penalties imposed for transgressions in the areas of creed, attire, and religion.

This study aims to analyze the urgency of qawa'id fiqhiyyah in the development of Islamic law. The rationale departs from the definition of the fiqhiyyah rule itself, namely a collection of syara' laws from various legal events that have the same 'illat. This meaning assumes that fiqhiyyah rules actually have a role in the development of Islamic law. Bearing in mind that each rule contains 'illat law, legal rationale and also philosophical values that can be used as a basis for establishing a law in a new case. This study uses a normative juridical method, with secondary data in the form of three legal materials, namely primary legal materials, secondary legal materials and tertiary legal materials. The data were taken from the literature as a data source, then analyzed and described systematically. The conclusions drawn are, 1) qawa'idh fiqhiyyah can be used as an alternative in resolving legal issues for which there is no explanation. 2) Qawa'id fiqhiyyah contains quite high dynamic values. 3), Qawa'id fiqhiyyah is able to realize legal elasticity to be applied in various contexts and. 4) Qawa'id fiqhiyyah contains the values of the contextualization of Islamic law.
