Current Balancing Control for Interleaved Half-Bridge Submodules in Modular Multilevel Converters
Authors: Viatkin Aleksandr , Ricco Mattia , Mandrioli Riccardo , Kerekes Tamas , Teodorescu Remus , Grandi Gabriele
Published: March 2022

This paper presents a closed-loop current balancing control for Modular Multilevel Converters with Interleaved half-bridge Sub-Modules (ISM-MMC). The new control loop solves the well-known problem of proper current balancing among interleaved half-bridge legs in each ISM-MMC submodule while preserving a simple and reliable structure. In addition to that, a novel capacitor voltage balancing strategy for MMCs is developed. The new algorithm contains main advantages of the classical capacitor voltage balancing methods while provides an opportunity to decouple two balancing tasks of ISM-MMC, namely capacitor voltage and interleaved legs current balancing. The proposed control methods feature good dynamic performance and are compliant with a digital processor's operational constraints. The effectiveness of the new balancing methods was verified during extensive numerical simulations and experimental tests on a laboratory prototype by the corresponding system response under the input/output characteristics variation and interleaved current control perturbation.
Interleaved Half-Bridge Submodules with Sensorless Leg Current Balancing in Modular Multilevel Converters

Published: March 2022

A new state observer-based current balancing method for Modular Multilevel Converters with Interleaved half-bridge Sub-Modules (ISM-MMC) is presented in this paper. The developed observer allows estimating currents through interleaved half-bridge legs in each submodule of ISM-MMC basing only on arm current and submodule’s capacitor voltage measurements. Then, the interleaved current balancing control uses the estimated currents to reduce the interleaved currents imbalance caused by upstream control actions. This technique minimizes the number of required current sensors in ISM-MMC, thereby reducing the converter's cost, weight, and volume. Capabilities of the proposed interleaved currents sensorless balancing control has been tested against standard parameter tolerances of the composing passive elements. The feasibility of the proposed method is verified by extensive simulation and experimental tests.
Reconstructing Semi-Markov Maps with Arbitrary Branch Monotonicity from Density Sequences
Authors: McDonald Andre , van Wyk Anton
Published: March 2022

This paper presents a novel solution to the inverse Frobenius-Perron problem of reconstructing an unknown nonlinear and ergodic map from causal sequences of probability density functions generated by the map. The original solution to this problem successfully reconstructs members of the canonical map class (i.e., a subset of the piecewise linear semi-Markov maps), provided all the map's branches are monotonically increasing. The original solution constructs a matrix estimate of the map's Frobenius-Perron operator, which governs the evolution of density functions under iteration of the map, from the density sequences. The one-dimensional map is reconstructed from this matrix. In contrast, the proposed solution constructs a higher-order matrix estimate of the Frobenius-Perron operator. A member of the newly proposed class of generalized hat maps, a superset of the canonical maps, is constructed from this matrix estimate. The proposed solution successfully distinguishes between increasing and decreasing map branches and enlarges the class of maps that can be successfully reconstructed to canonical maps with any subset of decreasing branches. When used to reconstruct any piecewise linear semi-Markov map, the proposed solution generates a map with consistent invariant density and power spectrum mode characteristics, regardless of the unknown map's canonicity or branch monotonicity. Numerical examples that illustrate the proposed solution's characteristics are presented.
Home Automation System Architecture based on FIWARE and Multi-Agent Systems
Authors: Martins Sofia , Kokkinogenis Zafeiris , Rosssetti Rosaldo
Published: March 2022

The continuous migration of people towards cities has led to an increase in resource consumption among homes, primarily in terms of energy and water. This phenomenon calls for resource management solutions in an attempt to drive sustainable consumption patterns. Among these solutions lie Home Automation Systems (HAS) capable of monitoring and controlling different appliances so as to deliver services such as appliance control and security surveillance. As in most HAS architectures today, these appliances are uniquely identified and connected to the Internet, as in Internet of Things (IoT) networks. Though, despite their potential, such architectures generally fail to address four essential features altogether: easy adaptability, access to remote services, interoperability and software portability. In this work, we propose a reference HAS architecture which implements the previous features. Our approach is based on the synergy between the FIWARE IoT middleware and a multi-agent system (MAS), leading to an autonomous IoT (AIoT) system. To demonstrate the applicability of this architecture and to evaluate its potential to drive sustainable resource consumption, we have deployed a Home Energy Management System (HEMS) in accordance with the proposed architecture, and gathered results of various simulations of a home environment managed by the HEMS. Our results suggest that the HEMS can aid home-owners in decision making, raise awareness as of their resource consumption profiles, and provoke behavioral changes leading to more sustainable consumption patterns.
Os Judeus Portugueses de Hamburgo
Authors: Martins Hugo
Published: March 2022

The present book investigates the social and religious history of the Portuguese-Jewish community of Hamburg during what may have been the most important period of its history - the second half of the seventeenth century. The political and economic rise of this small but influential community of New Christian bankers and merchants is analysed against the backdrop of its institutional dynamics, in an overall perspective never before conceived. The political, religious, economic, legal, charitable and disciplinary history of the community is thus explored through the analysis of the protocol books of the Portuguese Nation of Hamburg, written between 1652 and 1682. This is the intimate and fascinating journey of their everyday lives, hopes and challenges, as brought to us by their leaders.

Published: March 2022

The diagnosis of cystic echinococcosis (CE) is based on imaging, but it is recommended to use serological test to support imaging in inconclusive cases. We performed a retrospective analysis of serology results of patients with CE lesions, seen from January 2016 to March 2020, to evaluate the contribution of the serology in the diagnosis accuracy and sensitivity of CE. Sera from eligible patients, including 86 patients with probable CE lesion, were used, with 2 commercial seroassays (NovaLisaTM Echinococcus IgG; NovaTec Immunodiagnostica, Germany and Western Blot; ECHINOCOCCUS Western Blot (WB) IgG from LDBIO diagnostics). Sensitivity of seroassays to liver cyst wasn’t significantly higher than lung cyst, but a statically significant correlation has been found between positive CE serology and complicated cysts (82% versus 55% p<0.001). Sensitivity and diagnostic accuracy of ELISA test combined to Western blot (WB) were higher than those obtained with ELISA test alone (65% versus 82% p= 0,001). Combining a first level seroassays as ELISA test with a high specific test as WB provide the best diagnosis accuracy for CE.

Authors: Pole Maddi , Blamires Julie , Dickinson Annette
Published: March 2022

The aim of this quality improvement practice project was to improve noted delays in the time to antibiotic administration in paediatric febrile neutropenic patients seen at King Faisal Specialist Hospital and Research Centre (KFSH&RC), Saudi Arabia. Larrabee’s 6-step Model for Change of evidence-based practice guided the project. Clinical audit, nursing knowledge survey, comprehensive literature and international clinical guideline review were used to identify and design a clinical care pathway for paediatric febrile neutropenic patients at KFSH&RC. Post-implementation clinical audit showed a reduction in time to antibiotic administration and increased self-efficacy and knowledge among nursing staff in relation to managing the care of febrile neutropenic patients. This reflects similar improvements seen internationally in other centres following the introduction of a clinical pathway. This nursing led practice change was the first of its kind for KFSH&RC. It demonstrated that with support from key stakeholders, Larrabee’s model for evidence- based practice change can be used for introducing a nurse-led clinical care pathway in Saudi Arabia. Highlights •A new clinical care pathway introduced in Saudi Arabia improved time to antibiotic administration in paediatric febrile neutropenic patients. •Implementing a nurse-led clinical care pathway increased nurses’ confidence with managing children with febrile neutropenia and the skills and knowledge related to the accessing and delivering medication via central access devices •With key local stakeholder support evidence-based change frameworks such as that proposed by Larrabee can be used to improve nursing management in Saudi Arabia.

An Analysis of Speech Act Classification Used By The Characters In “Onward” Movie
Authors: Sakiti Galuh Fitriana
Published: March 2022

Introduction: Film is a symbol of real life portrait. This can be a debatable choice for the subject of discourse analysis because it resembles real-life conditions. Onward film is one of the films that depicts the use of English as a dialogue and highlights speech that conveys the classification of speech acts. Purpose: The purpose of this study was to investigate the types of speech acts uttered by the main character. In addition, this study will also investigate the purpose of characters using speech acts. Methods: This study uses a qualitative research with a pragmatism approach. The author applies the pragmatism theory developed by Yule (1996) with the types of speech acts: Declaration; Representative; Instruction; Commissive and Expressive. Results: The results reveal that; 1) Five speech acts are found in the film Onward with a total of 14 dialogues; 2) there are several purposes, each of which is used by the characters, the use of statements is mostly spoken by the police because only the police have a special role in the Onward Film. Conclusion: The use of representative speech acts used by the characters is to state what the speaker believes to be true or not. Directive speech acts are used by characters to ask someone to do something by ordering, suggesting, ordering, or asking. Commissive is used by characters to commit themselves to doing something they will do later. Finally, the use of expressiveness in the film Onward is to express feelings of pain, pleasure, sadness, and pleasure.

Determination of the stress-deformed state of cylindrical parts at circular oscillation of a sectorial working tool
Authors: Zaides S.A. , Ho Minh Quan
Published: March 2022

It is described the effect of the frequency of circular oscillations of a sectorial working tool on the stressstrain state of cylindrical parts. As a result of computer modeling, it was revealed that under the same loading conditions, the action of a working tool with different frequencies of circular oscillations creates different values of temporary and residual stresses. In the case of movement in one direction of the tool and the workpiece, the minimum value of stresses is formed, and with their oncoming movement, the value of the maximum stresses increases by 15...40 %. The resulting value of the residual stresses generally increases. With an increase in the frequency of circular oscillation of the working tool, the intensity of residual stresses increases by 1.2...2 times. The intensity of deformation changes in direct proportion to the value of the frequency of the circular oscillation and the depth of plastic deformation reaches 2.1...2.8 mm.

Исследование оптических изображений морских сюжетов с учетом статистических свойств сигнала для мониторинга морских глубин и затянувшихся объектов в настоящее время является актуальной темой, которой может быть использована для создания систем охраны окружающей среды через подводную экосистему. Среди различных областей исследований кодирование изображений широко применяются для сжатия и обеспечения надежной доставки видеоинформации по каналам связи. Одной из проблем, с которыми приходится сталкиваться при подводной связи, является низкая скорость передачи данных в акустических каналах, особенно при съемке изображений в глубоких водах, где нехватки света представляет собой серьёзную проблему для качественного восстановления сжатых изображений. Двумерное дискретное косинусное преобразование является основным механизмом, который используется для сжатия изображений. В работе приводится результаты тестирования алгоритмов сжатия с применением двух разных модификации путём изменения размера сегментов, подвергающихся спектральной обработке для обеспечения оперативной доставки и необходимой битовой скорости передачи с учетом пропускной способности канала связи.

The study of optical images of marine scenes, taking into account the statistical properties of the signal for monitoring the depths of the sea and lingering objects, is currently an urgent topic that can be used to create environmental protection systems through the underwater ecosystem. Among various fields of research, image encoding is widely used to compress and ensure reliable delivery of video information through communication channels. One of the problems that one has to face with underwater communication is the low data transfer rate in acoustic channels, especially when shooting images in deep waters, where the lack of light is a serious problem for high-quality restoration of compressed images. Two-dimensional discrete cosine transform is the main mechanism that is used for image compression. The paper presents the results of testing compression algorithms using two different modifications by changing the size of segments undergoing spectral processing to ensure prompt delivery and the required bit rate, taking into account the bandwidth of the communication channel.

Silica-rich garronite-Na was found together with epistilbite in Miocene basaltic rock from Shiratobana, Hirado Island, Nagasaki Prefecture in Japan for the first time. Garronite-Na occurs as an anhedral crystal that covers the center of a small cavity in altered basaltic rock, whereas the epistilbite covers the inside of the cavity. Electron probe microanalysis of the garronite-Na gives an empirical formula of (Na1.99K0.27)Σ2.26Ca1.61(Fe0.01Al5.31Si10.64)Σ15.96O32·14.3H2O on the basis of O = 32. Its Na/Ca molar ratio varies from 1.00 to 1.53, and its unit-cell parameters (space group I2) calculated from X-ray powder diffraction data are a = 9.983(11) Å, b = 10.089(14) Å, c = 10.070(10) Å, and β = 90.223(3)° with a calculated density of 2.183 g/cm3. Garronite-Na from Hirado Island formed from an alkaline high-silica solution in the later stages of hydrothermal zeolitization associated with volcanic activity.
A proxy measure of striatal dopamine predicts individual differences in temporal precision
Authors: Sadibolova Renata , Monaldi Luna , Terhune Devin B.
Published: March 2022

The perception of time is characterized by pronounced variability across individuals, with implications for a diverse array of psychological functions. The neurocognitive sources of this variability are poorly understood, but accumulating evidence suggests a role for inter-individual differences in striatal dopamine levels. Here we present a pre-registered study that tested the predictions that spontaneous eyeblink rates, which provide a proxy measure of striatal dopamine availability, would be associated with aberrant interval timing (lower temporal precision or overestimation bias). Neurotypical adults (N = 69) underwent resting state eye tracking and completed visual psychophysical interval timing and control tasks. Elevated spontaneous eyeblink rates were associated with poorer temporal precision but not with inter-individual differences in perceived duration or performance on the control task. These results signify a role for striatal dopamine in variability in human time perception and can help explain deficient temporal precision in psychiatric populations characterized by elevated dopamine levels.
Reading about minds: The social-cognitive potential of narratives
Authors: Eekhof Lynn S. , van Krieken Kobie , Willems Roel M.
Published: March 2022

It is often argued that narratives improve social cognition, either by appealing to social-cognitive abilities as we engage with the story world and its characters, or by conveying social knowledge. Empirical studies have found support for both a correlational and a causal link between exposure to (literary, fictional) narratives and social cognition. However, a series of failed replications has cast doubt on the robustness of these claims. Here, we review the existing empirical literature and identify open questions and challenges. An important conclusion of the review is that previous research has given too little consideration to the diversity of narratives, readers, and social-cognitive processes involved in the social-cognitive potential of narratives. We therefore establish a research agenda, proposing that future research should focus on (1) the specific text characteristics that drive the social-cognitive potential of narratives, (2) the individual differences between readers with respect to their sensitivity to this potential, and (3) the various aspects of social cognition that are potentially affected by reading narratives. Our recommendations can guide the design of future studies that will help us understand how, for whom, and in what respect exposure to narratives can advantage social cognition.
Problems when fixing the response bias parameter z in drift diffusion analysis
Authors: Alexandrowicz Rainer W. , Gula Bartosz
Published: March 2022

In a simulation study, Stafford et al. (Behavior Research Methods, 52, 2142–2155, 2020) explored the effect of sample size on detecting group differences in ability in the presence of speed–accuracy trade-offs using the Drift Diffusion Model (DDM) and introduced an online tool to perform a power analysis. They found that the DDM approach was superior to analyzing the observed response times and response accuracies alone. In their simulation, they applied the EZ method to estimate the model parameters. In this article, we demonstrate that the EZ method, which cannot estimate the response bias parameter of the DDM, causes severe estimation bias for all parameters if the true response bias is not 0.5. Moreover, the bias patterns differ between EZ and the equivalent maximum likelihood estimation with z fixed at 0.5. This should be taken into consideration when using the otherwise excellent power analysis tool for experimental designs, in which z≠ 0.5 cannot be ruled out or even stipulate it.

On the transitional forms of “fading” economic relations in the theoretical model of Noonomy
Authors:   Lomonosov Moscow State University, Khubiev K.A.
Published: March 2022

The Coronavirus Crisis and the Fourth Industrial Revolution, as the main drivers of global trend changes, have called for new scientific approaches to understanding the “new normal.” Theories based on the values of methodological individualism have shown their limitations and even their insolvency in the face of the new challenges. The virus was most successful in its spread where it encountered an individualism that had degenerated into egoism. The emergence of Noonomy, among other concepts, was a reaction to the insufficient potential of existing theories in the face of the challenges of the new era. The theoretical model of Noonomy relies on a perfect technology that provides citizens with the necessary benefits of life and frees them from the need for forced labor in production, and on new people, with creative motivation at the forefront and free from individualism. The article focuses on the fact that the transition from the current state of the economy, economic science and economic man to Noonomy and creative man is a great distance from the transitional states. The necessity of their research represents a global scientific task. The author justifies the necessity of such research, highlights some existing transitional forms and notes the emergence of new forms based on an evolving reality.

Current research paper aimed to investigate determinants of employee’s innovative work behavior in export SMEs. The general problem in some export SMEs was a lack of knowledge implementation and employee innovation to provide problem-solving. It employed a quantitative method with administered questionnaires distributed to 177 employees of the exporting SMEs. The research data were evaluated using SmartPLS 3.2.7. The result shows that transformational leadership was notably associated to organizational commitment, knowledge sharing, as well as innovative work behavior. Also, organizational commitment and knowledge sharing are double mediators between transformational leadership and innovative work behavior. There are some limitations of this research paper, such as the bias effects of using a self-assessment report. The possible implication is that managers need to understand the relationship between variables, particularly mediating mechanisms, to provide insightful information for enhancing positive leadership performance and innovation capability – the originality point toward a mediating linkage of transformational leadership and innovative work behavior. The research paper enrich to a body of knowledge where innovative work behavior was influenced by leadership style and behavior and predictors of organizational behavior.

Efforts with extreme-precision radial velocity (EPRV) instruments to detect small-amplitude planets are largely limited, on many timescales, by the effects of stellar variability and instrumental systematics. One avenue for investigating these effects is the use of small solar telescopes which direct disk-integrated sunlight to these EPRV instruments, observing the Sun at high cadence over months or years. We have designed and built a solar feed system to carry out “Sun-as-a-star” observations with NEID, a very high precision Doppler spectrometer recently commissioned at the WIYN 3.5 m Telescope at Kitt Peak National Observatory. The NEID solar feed has been taking observations nearly every day since 2020 December; data is publicly available at the NASA Exoplanet Science Institute NEID Solar Archive: https://neid.ipac.caltech.edu/search_solar.php. In this paper, we present the design of the NEID solar feed and explanations behind our design intent. We also present early radial velocity (RV) results which demonstrate NEID’s RV stability on the Sun over 4 months of commissioning: 0.66 m s−1 rms under good sky conditions and improving to 0.41 m s−1 rms under best conditions.

We derive a catalog of early-type emission-line stars including 30,023 spectra of 25,867 stars from LAMOST Data Release 7, in which 4189 have Simbad records. The spectra are classified into three morphological types (10 subtypes) based on Hα emission-line profiles. Some spectra contaminated by nebula emission lines such as from H ii regions are flagged in the catalog. We also provide a specific catalog of 20 stars with stellar winds or accretion flows by calculating the terminal and peak velocities based on P-Cygni or inverse P-Cygni profiles. More important, with two color–color diagrams, (H-Ks, J-H) and (Ks-W1, H-Ks), of a collection of known Herbig Ae/Be stars (HAeBes) and classical Ae/Be stars (CAeBes), we propose an updated criterion to separate HAeBes from CAeBes. By the criterion, we select 118 HAeBe candidates and 2636 CAeBe candidates from the sample. We confirm 71 of the 118 HAeBes based on the data from LAMOST (optical spectra) and WISE (photometry and images), 62 of which are newly identified. The 71 identified HAeBes are compiled into a specific catalog, and their SEDs and MIR images are also presented. The distances of 76% confirmed HAeBes are further than 1 kpc, which enlarges the number of known HAeBes in further distance. Most of the 71 HAeBes are located in the Galactic disk while 6 of them have ∣Z
gal∣ > 400 pc. Four HAeBes show the forbidden emission lines of [Fe ii] and [O i], in which J051425.20+411310.7 is a newly discovered B[e]. In addition, four HAeBes having Spitzer IRS spectra all show PAH features.

Authors: Atanasov Milen
Published: March 2022

The development of technologies allows the improvement of the algorithms for the operation of aviation systems for the delivery of special means to air and ground objects. The aim is to increase their efficiency, while facilitating the work of the crew in case of lack of time to complete the task. A mathematical model for the operation of this type of aviation systems for the supply of special equipment has been developed, which allows reducing the volume of the existing protocol for the implementation of the crew. It is proposed to use a common ballistic algorithm, combining different groups of special means of delivery to air and ground sites.
