Real-time Simulations on Ultracapacitor based UPQC for the Power Quality Improvement in the Microgrid
Authors: Kotla Rahul Wilson , Yarlagadda Srinivasa Rao
Published: February 2022

Penetration of renewable energy systems (RES) into microgrid (MG) increases rapidly due to the intensified energy demands by the distribution level consumers. To meet this demand, consumers are erecting small scale distribution renewable energy generating systems (DREGS) which mostly constitutes of solar photovoltaic systems. Injecting power from the DREGS to the MG will rise potential problems like real and reactive power distortions, sag/swells which affect the power quality of the system. Voltage sags and swells are normally caused by MG intermittencies which occur at the high power and low energy situations. In order to maintain the power quality of the MG during intermittencies, an ultracapacitor (UC) is integrated along with a unified power quality conditioner (UPQC) with the DREGS is proposed in this paper. Basically, an ultracapacitor is a high power and low energy density device that will compensate the MG intermittencies. This proposed system deals with the control and design aspects of the ultracapacitor, a bidirectional converter for charging and discharging of UC, and a UPQC. The UPQC will act as a dynamic voltage restorer (DVR) for the MG side and an active power filter (APF) for the load side. The proposed system is designed and modelled using Matlab/Simulink platform and the results were analyzed.

Published: February 2022

For grid-connected applications, Multi-level Inverters (MLI) are mostly used, similarly to join the various RES to the grid as well as to satisfy the load demand MLIs are mostly preferred. This article presents a fuel cell-based high-gain boost converter with a single-phase five-level inverter controlled by CB-PWM techniques. A fuel cell produces a very less amount of power so to boost-up the fuel cell power to the essential power level with the help of a high-gain boost converter. The boost converter produces the required DC output power and that power is a converter to required AC power by using a single-phase five-level inverter. The MLI switches are controlled with the help of MC-PWM techniques and observe the inverter behavior in terms of THD, output ripples, and settling time. The entire work is done in MATLAB/Simulink tool as well as design a small prototype model by using the FPGA board.

Authors: Velasco Gómez Sara María , Pérez Londoño Sandra Milena , Mora Flórez Juan José
Published: February 2022

Objective: This paper presents a qualitative comparison of different recently proposed network protection schemes that are based on the distance function. From this comparison, possible opportunities are identified to develop strategies oriented towards protecting active distribution systems.
Methodology: This research is carried out in two parts: the first is to identify the fundamental theoretical aspects of distance protection, its main problems, and a description of the most important aspects of the relevant strategies proposed in recent years. The second part consists of selecting aspects and elaborating a qualitative comparison of the different protection schemes analyzed. This comparison makes it possible to establish the advantages and disadvantages of each of the relevant proposals used in conventional electrical networks or active distribution networks.
Results: As a result of this research, the most important aspects to consider in the protection design are identified, which therefore strongly affect its performance. These are summarized in a comparative table, which supports future research related to distance protection in active distribution networks.
Conclusions: From this research, it can be stated that the solutions analyzed, despite being relevant within the scope of distance protection applied to active distribution networks, have problems to solve. None of these strategies protects the network for all types of failures in a selective, sensitive, reliable, and cost-effective way while guaranteeing minimum supply interruption to consumers.

Review of Charging Load Modeling Strategies for Electric Vehicles: a Comparison of Grid-to-Vehicle Probabilistic Approaches
Authors: Zuluaga Ríos Carlos David , Florián Ceballos Daniel Felipe , Rojo Yepes Miguel Ángel , Saldarriaga Zuluaga Sergio Danilo
Published: February 2022

Objective: In this paper, we review different approaches to how the penetration of electric vehicles (EV) can be modeled in power networks. We also evaluate and compare experimentally the performance of three probabilistic electric vehicle charging load approaches considering four levels of penetration of EV.

Methodology:  We carry out a detailed search of the state-of-the-art in charging load modeling strategies for electric vehicles, where the most representative works on this subject were compiled. A probabilistic model based on Monte Carlo Simulation was proposed and two more methods were implemented. These models take into account the departure time of electric vehicles, the arrival time and the plug-in time, which were conceived as random variables.  

Results:  Histograms of the demand for charging of electric vehicles were obtained for the three models contemplated. Additionally, a similarity metric was calculated to know the distribution that best fits the data of each model. The above was done considering 20, 200, 2000 and 20,000 electric vehicles on average. The results show that if there are a low penetration of electric vehicles, it is possible to model the EV charging demand using a gamma distribution. Otherwise, it is recommended to use a Gaussian or Lognormal distribution if you have a high VE penetration.

Conclusions: A review of the state of the art of the modeling of electric vehicles under a G2V approach was presented, where three groups are identified: the deterministic approaches, methods that deal with uncertainty and variability, and finally data driven methods were also identified. Additionally, we observed that the EVCP model 3 and the gamma distribution can be appropriate for modeling the penetration of EVs in probabilistic load flow analysis or for stochastic planning studies for active distribution networks.

The Development of a Quantum-based Ontology for the Description of the Reality Experienced in NDEs by Using Computerized NLP Analytics
Authors: Valverde Raul , Swanson Chet
Published: February 2022

According to the survival hypothesis, a person's personality and consciousness survive the death of the physical body. Ontology is a well-established theoretical branch of philosophy concerned with representations of reality. This research proposes the use of computer natural language processing (NLP), databases, structured query language and near-death experiences (NDEs) narratives to develop a quantum ontology based on the quantum hologram theory of physics and consciousness. This research proposes the use of a quantum ontology to represent the incomprehensible aspects of near-death experiences. The research demonstrates how to validate ontology constructs within a quantum ontology, demonstrating the methodology's potential for the development of a consciousness model based on the quantum paradigm.
A novel mutation in TRAC in a patient with abnormal newborn screening for severe combined immunodeficiency
Authors: Garkaby Jenny , Abrego Fuentes Laura Edith , Willett Pachul Jessica , Watts-Dickens Abby , Fraser Meghan
Published: February 2022

Background: The T cell receptor (TCR)-α chain plays a key role in TCR structure and function. Biallelic mutations in TRAC, encoding the constant region of the TCR-α chain, obliterates TCR expression and results in immunodeficiency. TCR-α chain deficiency presents at infancy or childhood with repeated viral and bacterial infections, enlarged liver, spleen, and lymph nodes as well as autoimmune features and lymphoma (OMIM #615387).

Aim: To broaden the genotypic and phenotypic spectrum of TCR-α chain deficiency.

Methods: We present a case report of a patient with severe combined immunodeficiency (SCID) due to a novel autosomal recessive mutation in TRAC.

Results: Our patient was identified at 13 days of life due to abnormal T cell receptor excision circle levels detected by newborn screening (NBS). Immune evaluation revealed profound lymphopenia, depressed responses to the mitogen PHA and a skewed T cell repertoire, all consistent with SCID. The patient was found to carry a novel homozygous mutation in the TRAC gene.

Conclusion: A novel homozygous mutation in the TRAC gene caused profound T cell lymphopenia and aberrant in vitro mitogenic response, the hallmarks of SCID.

Statement of Novelty: TCR-α chain deficiency is a rare and relatively new condition and not very well defined. We herein report a novel mutation in TRAC resulting in SCID.

Objectives

Hemolysis is associated with erroneous or delayed results. Objectives of the study were to compare four different methods for obtaining hemolysis in vitro on three different analyzers.

Methods

Hemolysis was prepared with addition of pure hemoglobin into serum pool, osmotic shock, aspiration through blood collection needle, freezing/thawing of whole blood. Biochemistry parameters were measured in duplicate at Architect c8000 (Abbott, Abbott Park, USA), Beckman Coulter AU680 (Beckman Coulter, Brea, USA) and Cobas 6000 c501 (Roche, Mannheim, Germany), according to manufacturers’ declarations. Cut-off value was defined as the highest value of H index with corresponding bias lower than acceptance criteria.

Results

We were not able to obtain results with freezing protocol. On all three platforms, lowest number of analytes were sensitive to hemolysis at H=0.5 using method of adding free hemoglobin. When osmotic shock was used, cut-off values for the most analytes were generally met at lower values. Hemolysis significantly interfered with measurement of potassium and lactate dehydrogenase (LD) at H=0.5 on all platforms. The most of the tested analytes had the lowest acceptable H index when aspiration method was used. At the low level of hemolysis (H=0.8) glucose, sodium, potassium, chloride, phosphate, and LD were affected on all analyzers, with some additional analytes depending on the manufacturer.

Conclusions

Hemolysis interference differs on different analyzers and according to protocol for obtaining hemolysis. Aspiration method was generally the most sensitive to hemolysis interference, while addition of free Hb was the most resistant.
Automatic multimodal sensor calibration of the UNICARagilvehicles
Authors: Kinzig Christian , Horn Markus , Lauer Martin , Buchholz Michael , Stiller Christoph , Dietmayer Klaus
Published: February 2022

Automated vehicles rely on a precise intrinsic and extrinsic calibration of all sensors. An exact calibration leads to accurate localization and object detection results. Especially for sensor data fusion, the transformation between different sensor frames must be well known. Moreover, modular and redundant platforms require a large number of sensors to cover their full surroundings. This makes the calibration process complex and challenging. In this article, we describe the procedure to calibrate the full sensor setup of a modular autonomous driving platform, consisting of camera, lidar, and radar sensors, in four subsequent steps. At first, the intrinsic and extrinsic camera parameters are determined. Afterwards, the transformation from lidar to camera on the one hand and from lidar to radar on the other hand is estimated. Lastly, the extrinsic calibration between all lidars and the vehicle frame is performed. In our evaluation, we show that these steps lead to an accurate calibration of the complete vehicle.

Published: February 2022

Three optically active Molybdenum (VI) dioxo complexes with tetrahydro salen and substituted tetrahydro salen derivatives as ligands were synthesized and examined as catalysts for asymmetric epoxidation. Complexes of the type MoO2(L)(Solv) and WO2(L) (L = tridentate, trans-2- aminocyclohexanol derived chiral Schiff base, Solv = alcohol) were prepared and characterized by elemental analysis, NMR and IR spectroscopy. These complexes are applicable as catalysts for olefin epoxidation reactions with tert-butyl hydroperoxide (TBHP) being the oxidizing agent. In case of cis-β -methylstyrene moderate enantiomeric excesses of up to 26% can be reached when the reaction is carried out at 0 ◦C.
Oxygen evolving reactions catalyzed by different manganese oxides: the role of oxidation state and specific surface area
Authors: Becker Stefanie , Behrens Malte
Published: February 2022

A set of the four manganese oxide powders α-MnO2 (hollandite), δ-MnO2 (birnessite), Mn2O3 (bixbyite), and Mn3O4 (hausmannite) have been synthesized in a phase-pure form and tested as catalysts in three different oxygen evolution reactions (OER): electrochemical OER in KOH (1 mol L−1), chemical OER using aqueous cerium ammonium nitrate, and H2O2 decomposition. The trends in electrochemical (hollandite >> bixbyite > birnessite > hausmannite) and chemical OER (hollandite > birnessite > bixbyite > hausmannite) are different, which can be explained by differences in electric conductivity. H2O2 decomposition and chemical OER, on the other hand, showed the same trend and even a linear correlation of their initial OER rates. A linear correlation between the catalytic performance and the manganese oxidation state of the catalysts was observed. Another trend was observed related to the specific surface area, highlighting the importance of these properties for the OER. Altogether, hollandite was found to be the best performing catalyst in this study due to a combination of the high manganese oxidation state and a large specific surface area. Likely, due to a sufficient electrical conductivity, this intrinsically high OER performance is also found to some extent in electrocatalysis for this specific example.

Authors: Nagatani Tsuyoshi , Haff G. Gregory , Guppy Stuart N. , Kendall Kristina L.
Published: February 2022

Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals need to better understand how different set configurations affect the training adaptations that result from resistance training. Traditional and cluster set structures are commonly implemented by strength and conditioning professionals as part of an athlete's resistance training program. The purpose of this review is to offer examples of the practical implementation of traditional and cluster sets that can be integrated into a periodized resistance training program.

Published: February 2022

The objective of our paper is to investigate the optimal control of semilinear population dynamics system with diffusion using semigroup theory. The semilinear population dynamical model with the nonlocal birth process is transformed into a standard abstract semilinear control system by identifying the state, control, and the corresponding function spaces. The state and control spaces are assumed to be Hilbert spaces. The semigroup theory is developed from the properties of the population operators and Laplacian operators. Then the optimal control results of the system are obtained using the C0-semigroup approach, fixed point theorem, and some other simple conditions on the nonlinear term as well as on operators involved in the model.

Abstract. The development of Integrated Islamic schools is in line with the increasing symptoms of religious conservatism whose roots can be found from tarbiyah movements on public campuses, such as UGM, UI, ITB. In general, Integrated Islamic individuals or groups present themselves with an Islamic identity by returning to "authentic Islam", as practiced by the salaf ash-shalih. Unfortunately, the concept of authenticity differs from one group to another. This article concludes that the Integrated Islamic School is not only aimed at transmitting Islamic teachings, but also as an effort to encourage people to be more Islamic.Keywords: Transnational Islam, Integrated Islamic Schools, PKS and Urban Communities.Abstrak.

Abstract. Incumbency status, position number on the ballots, and information dissemination level are indicators of voters' evaluation ability. This article will test the correlations of seat winnings, incumbency status, and candidate's position number on the ballot to explain the voters' evaluation ability in the 2019 Banten Province general election. The test results found that the incumbent status and the position number on the ballot correlate to the winning of seats. The results of the analysis show that incumbents have a greater chance of winning a seat than non-incumbents. It also shows that if the candidates have a position number on the ballot close to the first number, the vote gain is higher and vice versa. This article argues that incumbents and well-positioned candidates would win due to the limited ability of voters to evaluate all candidates and moderated by the lack of information on legislative candidates.Keywords: Incumbency Advantages, Ballot Position Effect, Voter Evaluation Ability, Seat Winnings.Abstrak. Kemenangan petahana Dewan Perwakilan Rakyat (DPR) dan calon DPR yang memiliki posisi nomor urut atas, serta kondisi persebaran informasi pemilihan legislatif yang rendah memungkinkan indikasi lemahnya kemampuan evaluasi para pemilih.

OBJECTIVE

Children with autism spectrum disorder (ASD) have difficulty participating in dental care and experience significant unmet dental needs. We examined the efficacy of parent training (PT) for improving oral hygiene and oral health in underserved children with ASD.

METHOD

Families of Medicaid-eligible children with ASD (ages 3–13 years, 85% boys, 62% with intellectual disability) reporting difficulty with dental care participated in a 6-month randomized controlled trial comparing PT (n = 60) with a psychoeducational dental toolkit (n = 59). Primary outcomes were parent-reported frequency of twice-daily toothbrushing and dentist-rated visible plaque. Secondary outcomes included parent-reported child behavior problems during home oral hygiene and dentist-rated caries. Dentists were blind to intervention assignment. Analyses were intention to treat.

RESULTS

Retention was high at posttreatment (3 months, 93%) and 6-month follow-up (90%). Compared with the toolkit intervention, PT was associated with increased twice-daily toothbrushing at 3 (78% vs 55%, respectively; P < .001) and 6 (78% vs 62%; P = .002) months and a reduction in plaque at 3 months (intervention effect, −0.19; 95% confidence interval [CI], −0.36 to −0.02; P = .03) and child problem behaviors at 3 (−0.90; 95% CI, −1.52 to −0.28; P = .005) and 6 (−0.77; 95% CI, −1.39 to −0.14; P = .02) months. Comparatively fewer caries developed in children receiving the PT intervention over 3 months (ratio of rate ratios, 0.73; 95% CI, 0.54 to 0.99; P = .04).

CONCLUSIONS

PT represents a promising approach for improving oral hygiene and oral health in underserved children with ASD at risk for dental problems.

Prolactin-secreting pituitary tumour is a rare disease, in which excess prolactin causes significant functional and constitutional disorders of the whole body. Hyperprolactinaemia is associated with changes in body composition and metabolic disorders. The long-term prognosis and quality of life in patients with prolactinoma are mainly influenced by cardiovascular disorders, which, if left untreated, increase the cardiovascular risk and limit the treatment options for secondary organ complications. Cardiovascular mortality in patients with prolactinoma is several times higher than in the general population. Early diagnosis of prolactin-releasing pituitary tumour and a thorough morphological and functional cardiovascular assessment at each stage of the disease are necessary for risk stratification. Patients with prolactinoma should be put on combined treatment based on both serum prolactin control, and reduction of cardiovascular risk factors. Normalisation of prolactin levels and reduction of the tumour mass, achieved mainly through effective pharmacotherapy, reduce mortality and the risk of cardiovascular complications; therefore, the earliest possible diagnosis of prolactin pituitary tumour and implementation of appropriate treatment as well as active diagnosis and therapy of coexisting organ complications should be set as a goal in these patients. It seems that a thorough cardiological assessment of patients with prolactinoma should be obligatory, regardless of their age or the time of diagnosis. The aim of this study was to present the complexity of clinical problems in patients with prolactin secreting pituitary tumours, who require special interdisciplinary care.

It is estimated that 30–80% of the population in Europe and the United States experience frequent and recurrent headaches, the most common of which are tension-type, migraine and cluster headaches. Migraine can also overlap with tension-type headache, which is referred to as vasomotor or mixed headache. According to the 3rd edition of the International Classification of Headache Disorders (ICHD-3 beta), these entities are classified as idiopathic (primary) headaches, where pain is both the essence and the main symptom of the disease. Idiopathic headaches are difficult to diagnose as they differ mainly in intensity. When collecting medical history, the focus should be placed on the duration and location of pain. Therefore, a thorough interview to assess subjective pain intensity is one of the basic elements of the diagnostic workup. Tension-type headache, migraine and cluster headaches are also characterised by specific symptoms, identification of which is essential for the diagnosis. Cluster headache produces the most typical symptoms. Since these types of headaches require different therapeutic strategies, it is necessary to differentiate them. Their treatment requires interdisciplinary cooperation of, among others, dentists, neurologists, and physiotherapists. In this paper, we made an attempt to discuss the pathogenesis, symptoms and differential diagnosis of tension headache, migraine and cluster headache, based on literature review.

Pressure suits are used primarily to protect a pilot against increased G-forces and adverse effects of atmospheric pressure at high altitudes. However, pressure suits can also potentially be used for kinesitherapy in patients with orthopaedic, neurological and cognitive deficits, including in those with Asperger syndrome or autism. For this reason, pressure suits have been adapted for therapeutic purposes (rehabilitation). These suits have been named R-WUK. Results obtained in a pilot group show additional possibilities for the application of R-WUK suits in autism therapy and provide a different perspective on the problem of autism spectrum disorder therapy. The innovativeness of this approach is based on the fact that it does not involve any psychological, educational or pharmacological therapies; instead, it employs kinesitherapy with a system that primarily creates physical effects: the suit exerts pressure on the patient’s tissues using pneumatic mechanisms. The present approach also involves the use of physiotherapy methods such as PNF, NDT/Bobath and Stand&Go. As a result of the study intervention, significant changes were observed in the patients’ functioning and behaviour. The changes were so significant that it can be concluded that patients who have undergone R-WUK suit therapy function as neurotypical individuals. A low number of subjects in the study group does not allow one to make a definitive determination that all individuals with autism or Asperger syndrome will undergo similar changes in functioning as a result of the suit therapy.

Published: February 2022

Purpose

The goal of our review was to gather information on the most important community-acquired and hospital-acquired co-infections among coronavirus disease 2019 (COVID-19) patients, and to examine not only the effect of these co-infections on disease outcomes but also to identify the possible risk factors that predispose COVID-19 patients to co-infections.

Methods

Medline (PubMed) and Google Scholar were searched for relevant articles published between January 1st, 2020, and September 31st, 2021, on the topic of co-infections among COVID-19 patients.

Results

Among community-acquired and hospital-acquired co-infections, bacterial and fungal co-infections are equally frequent, followed by viral co-infections that affected a relatively smaller portion of patients. Overall, co-infections were more frequent in the hospital than at the community level. Risk factors for acquiring co-infections include male gender, longer length of hospital stay, presence of supportive treatment, such as ventilation, the admission to intensive care units, the administration of medications, such as steroids or antibiotics, and certain blood parameters, such as high C-reactive protein or lymphopenia. The presence of co-infections could aggravate the COVID-19 disease severity, prolong the healing time of patients, and lead to worse disease outcomes overall.

Conclusion

Co-infections may increase the mortality of COVID-19 patients, especially in the hospital setting. Paying closer attention to hygiene, adhering to diagnostic and therapeutic protocols, implementing antimicrobial stewardship programs could decrease the occurrence of co-infections and lead to improved outcomes for COVID-19 patients.

Konzeption und Implementierung eines Künstlichen Neuronalen Netzes zur Situationserkennung mit humanoiden Robotern anhand mehrerer Eingangskanäle
Authors:   , Ziemert Lara
Published: February 2022

In dieser Masterarbeit soll eine Architektur für ein Künstliches Neuronales Netz erarbeitet werden, mit der mehrere Eingangskanäle eines humanoiden Roboters für eine Situationserkennung zusammengefasst werden können. Dazu werden zunächst die Grundbausteine für eine Situationserkennung am Beispiel des menschlichen Gehirns untersucht und die Erkenntnisse auf die Arbeitsweise Künstlicher Neuronales Netze übertragen. Anschließend wird ein Konzept für eine Situationserkennung auf humanoiden Robotern erstellt. Dazu werden mögliche Situationen konstruiert und die Aufgabe der Situationserkennung so formuliert, dass sie mit einem Künstlichen Neuronalen Netz bearbeitet werden kann. Daraufhin werden mögliche Architekturen für dieses Netz verglichen und die am besten geeignetste ausgewählt. Das erstellte Konzept soll im Rahmen dieser Arbeit auf dem Tisch-Roboter ROS-E umgesetzt werden. Dazu soll eine Trainings- und Testumgebung geplant und umgesetzt werden. Nachdem das entwickelte Künstliche Neuronale Netz trainiert und getestet wurde, wird ausgewertet, ob die ausgewählte Architektur für eine Situationserkennung auf humanoiden Robotern geeignet ist.

Authors:   National University of Ukraine on Physical Education and Sport, Kyiv, Ukraine, Bulhakova T. M.
Published: February 2022

The relationship between the meaning of life, mechanisms of psychological defenсe and self-actualization of student-athletes are revealed in the article. A theoretical analysis of psychological and pedagogical research has shown that in the modern scientific literature there is no unambiguous view of the concept of the meaning of life. The theme of the meaning of life refers to eternal existential problems and is in the field of vision of philosophers and psychologists throughout the history of mankind. The processes of acquiring the meaning of his being by a person, its influence on a person’s life are an actual subject of the study of psychological science. The meaning of life can be considered a certain idea that is important for life. At the present stage, enough scientific facts have been accumulated that allow us to say that the meaning of life is not only a separate idea, but also a psychological phenomenon that has its own characteristics of formation, its own levels of development. After reaching a certain stage of development, it has a significant impact on human life. Three relevant techniques were selected in the work for this. The correlations between the empirically obtained indicators were revealed and the corresponding methodological recommendations were formulated.

Art in evidence-based nursing practice from the perspective of Florence Nightingale
Authors: Lima José Janailton de , Miranda Karla Corrêa Lima , Cestari Virna Ribeiro Feitosa , Pessoa Vera Lúcia Mendes de Paula
Published: February 2022

ABSTRACT Objectives: to discuss, in the light of Florence Nightingale, the historical position of art as a constituent device of evidence-based nursing practice. Methods: reflective study anchored in the writings of Nightingale and other researchers with whom it is possible to have a profound dialogue on the theme “art in nursing”. Results: art is related to two essential elements in the practice of nursing: knowledge and skill. Understanding science as knowledge and art as skill leads to the idea that both make it possible to combine technical competence, compassion, ethics, and individualization of care. Final Considerations: the art of nursing is the continuous exercise of detailed perception, so that the subjective aspect becomes the center to which the nurse’s gaze converges, that which will allow them to unveil the “truth” posed by the patient, resulting in the best intervention for him.
