The estimate of amplitude and phase of harmonics in power system using the extended kalman filter

Received Jan 9, 2021 Revised Apr 13, 2021 Accepted May 29, 2021 Nowadays, the amplitude of the harmonics in the power grid has increased unwittingly due to the increasing use of the nonlinear elements and power electronics. It has led to a significant reduction in power quality indicators. As a first step, the estimate of the amplitude, and the phase of the harmonics in the power grid are essential to resolve this problem. We use the Kalman filter to estimate the phase, and we use the minimal squared linear estimator to assess the amplitude. To test the aforementioned method, we use terminal test signals of the industrial charge consisting of the power converters and ignition coils. The results show that this algorithm has a high accuracy and estimation speed, and they confirm the proper performance in instantaneous tracking of the parameters.
Determining subject headings of documents using information retrieval models

Subject heading is a controlled vocabulary that describes the topic of adocument, which is important to find and organize library resources. Assigning appropriate subject headings to a document, however, is a time-consuming process. We therefore conduct a novel study on the effectiveness of information retrieval models, i.e.,language model (LM) andvector spacemodel (VSM), to automatically generate a ranked list of relevant subject headings, with the aim to give a recommendation for librarians to determine the subject headings effectively and efficiently. Our results show that there are a high number of our queries (up to 61%) that have relevant subject headings in the ten top-ranked recommendations and on average, the first relevant subject heading is found at the early position (3rd rank). This indicates that document retrieval methods can help the subject heading assignment process. LM and VSM are shown to have comparable performance, except when the search unit is title, VSM is superior to LM by8-22%. Our further analysis exhibits three faculty pairs that are potential to have research collaboration as their students’ thesis often have overlap subject headings: i) economy and business-social and political sciences, ii) nursing-public health and iii) medicine-public health.
Genetic and environmental correlations between complex phenotypes differ by race/ethnicity and sex

We developed novel closed-form estimators of genetic and environmental correlation coefficients. We applied them to estimate over 4,000 genetic and environmental correlations between multiple phenotypes in a diverse sample from the Trans-Omics in Precision Medicine (TOPMed) program. We found substantial differences in heritabilities, genetic, and environmental correlations of multiple phenotypes and phenotype-pairs between Black, Hispanic/Latino and White populations as well as between sexes. Finally, we quantified genetic and environmental correlations between phenotypic domains, each characterized by multiple phenotypes. Altogether we provide a novel, in-depth framework for examining relations among complex human phenotypes and their determinants.
Reducing Domain Shift For Mitosis Detection Using Preprocessing Homogenizers

The detection of mitotic figures in histological tumor images plays a vital role in the decision-making of the appropriate therapy. However, tissue preparation and image acquisition methods degrade the performances of the deep learning-based approaches for mitotic figures detection. MIDOG challenge addresses the domain-shift problem of this detection task. This work presents our approach based on preprocessing homogenizers to tackling this problem.
Effect of Blast Loading on Seismically Detailed RC Columns and Buildings

Explosions caused by standoff charges near buildings have drastic effects on the internal and external structural elements which can cause loss of life and fatal injuries in case of failure or collapse of the structural element. Providing structural elements with blast resistance is therefore gaining increasing importance. This paper presents numerical investigation of RC columns with different reinforcement detailing subjected to near-field explosions. Detailed finite element models are made using LS-DYNA software package for several columns having seismic and conventional reinforcement detailing which were previously tested under blast loads. The numerical results show agreement with the published experimental results regarding displacements and damage pattern. Seismic detailing of columns enhances the failure shape of the column and decrease the displacement values compared to columns with conventional reinforcement detailing. Further, the effect of several modeling parameters are studied such as mesh sensitivity analysis, inclusion of air medium and erosion values on the displacements and damage pattern. The results show that decreasing the mesh size, increasing erosion value and inclusion of air region provide results that are very close to experimental results. Additionally, application is made on a slab-column multistory building provided with protective walls having different connection details subjected to blast loads. The results of this study are presented and discussed. Use of a top and bottom floor slab connection of protective RC walls are better than using the full connection at the four sides to the adjacent columns and slabs. This leads to minimizing the distortion and failure of column, and therefore it increases the chance of saving the building from collapse and saving human lives.

Materials and Methods: Cross-sectional questionnaires were developed, and they included the perceived stress scale and questions about potential sources of stress. A sample size of 180 was determined using a 0.05 level of significance and a precision of ±8%. The survey was distributed using a consecutive non-random sampling method to all oral and maxillofacial surgeons and residents in all regions in Saudi Arabia from May to December 2019. Results: One hundred and seventy-two responses were received. Males were the predominant gender. The perceived stress scale revealed a moderate stress level among surgeons and residents. However, residents had a significantly higher score (P = 0.005). Increased working days were significantly associated with higher stress levels (P = 0.006). Long on-call periods were significantly and positively correlated with increased stress levels among residents since their work schedule was not flexible (P = 0.000). The majority of surgeons and residents believe that they have unconducive and stressful work environments and that working as a maxillofacial surgeon is stressful. Conclusion: The study results suggest that there is increased occupational stress among oral and maxillofacial surgeons and residents in Saudi Arabia. This study highlights the need for stress management programs to minimize stress factors at the workplace and to ensure a healthy working environment for the practitioners.
Composition, structure, and physicochemical characteristics of pigeon pea (Cajanus cajan) starches from Indonesia

A’yuni NRL, Marsono Y, Marseno DW, Triwitoyo P. 2021. Composition, structure, and physicochemical characteristics of pigeon pea (Cajanus cajan) starches from Indonesia. Biodiversitas 22: 3430-3439. Information on the characteristics of pigeon pea (Cajanus cajan (L.) Millsp. ) starch would provide a scientific basis for developing its application. However, data about characteristics of pigeon pea starch, especially from the Southeast Asia region, has been limited. This study determined the composition, structure, and physicochemical characteristics of pigeon pea starches from three different Indonesian regions, i.e., Bali, Yogyakarta, and West Nusa Tenggara (NTB). We also investigated the potential application of Indonesian pigeon pea starches. Pigeon pea starch was extracted using a wet method, and then pigeon pea starch was characterized. The yield of pigeon pea starches ranged from 29.83-31.68%. Pigeon pea starches showed a significant difference (P<0.05) in amylose content (54.74-58.51%), relative crystallinity (24.20-28.97%), waterbinding capacity (0.70-0.76 g/g), oil binding capacity (0.55-0.58 g/g), swelling power (13.19-14.52 g/g), and solubility (9.48-11.15%). The pasting properties (except for final viscosity) and thermal properties (except for onset temperature and gelatinization enthalpy) differed significantly. Granules of pigeon pea starch were oval to elliptical, with a mean granule diameter of 18.41-19.98 μm. According to X-ray diffraction patterns, pigeon pea starches showed CA type, contained orthorhombic and hexagonal crystals. Pigeon pea starches also showed the same FTIR spectra. The results revealed that the differences in pigeon pea growing locations affect pigeon pea starch's composition and physicochemical properties. The highest amylose content and lowest relative crystallinity were found in Yogyakarta pigeon pea starch. In the future, our findings could be used to develop pigeon pea starch for various food applications.
Pozytywne zachowania zdrowotne studentów lubelskich uczelni i ich wybrane uwarunkowania

INTRODUCTION: According to modern knowledge, we distinguish many factors conditioning human health. Among them, the most important is lifestyle. During the university education period, the first independent attempts and decisions are made, not only those related to life choices, but also decisions related to health behaviours that will have a consequence in adult life. The aim of the study was to assess the positive health behaviours among students of Lublin universities and their selected determinants. MATERIAL AND METHODS: The study was conducted using the PAPI method from March to May 2017 among 410 male students. The study employed the Positive Health Behaviour Scale (PHBS) for adults and sociodemographic questions. The results of the study were subjected to statistical analysis. RESULTS: The obtained results of the study carried out among students using PHBS allowed the authors to state that the respondents obtained the highest result in Subscale IV. “Safety” (2.46 ± 0.59), subsequently in Subscale III. “Relaxation and behaviours connected with psychosocial health” (1.67 ± 0.53). The lowest rated subscale was Subscale I. “Nutrition” (1.28 ± 0.52). Statistical analysis showed that age, the place of residence, place of residence during studies, field of studies, occurrence of cancer in the family and self-assessment of health condition determines the assessment of positive health behaviours (p < 0.05). CONCLUSIONS: The ranking of positive health behaviours among male students of Lublin universities is as follows: “Safety”, “Relaxation and behaviours connected with psychosocial health”, “Physical activity”, “Taking care of one’s body” and “Nutrition”.
A randomized split mouth clinical trial of the application of the desensitizer agents for tooth sensitivity

Background: Dentin hypersensitivity (DH) affects 3%-75% of the people and is one of the morbid tooth conditions. Hence in the present study we aim to examine the clinical effectiveness of 3 different desensitizing agents in decreasing pain of DH in time of 1 month. Methods: Fifty subjects with cervical DH in at least one tooth in any three of the 4 quadrants were selected. VAS was used to note the pain. Each quadrant in an individual was randomly assigned. Profluorid varnish, Admira protect, and PRG‐Barrier coat was used. VAS scores for the tactile and air stimuli were noted immediately after application, 1 week, and after 1 month. The data was analyzed keeping p<0.05 as significant. Results: VAS significantly reduced for all three groups from the base line (p<0.001). Admira protect showed significant reduction of hypersensitivity scores at 1 month compared to other groups (p<0.001). Conclusions: Admira protect was better at lowering the pain due to DH than PRG‐barrier coat and Profluorid varnish after 1 month of application.
Evaluation of Toraja (Indonesia) local aromatic rice mutant developed using heavy-ion beam irradiation

Okasa AM, Sjahril R, Riadi M, Mahendradatta M, Sato T, Toriyama K, Ishii K, Hayashi Y, Abe T. 2021. Evaluation of Toraja (Indonesia) local aromatic rice mutant developed using heavy-ion beam irradiation. Biodiversitas 22: 3474-3481. The aromatic local Toraja rice "Pare Bau" has a good grain quality and aroma. However, it has some disadvantages, including a late heading and low yield for a modern farming system. This study aims to evaluate and select early heading as well as high yield mutant lines induced by heavyion beam irradiation. Furthermore, dry seeds of Pare Bau were irradiated with Argon-ion (300 keV/μm) and Carbon-ion (30 keV/μm) at RI-beam factory, RIKEN Nishina Center, Japan. The germination percentages of the M1 seeds were 49% for Pare Bau irradiated with Argon-ion (PB-A), 53% for Pare Bau irradiated with Carbon-ion (PB-C), and 70% for the Control. The 13 PB-A and 13 PB-C M1 plants were selected, and the seeds were sampled in the paddy field of Hasanuddin University (20 m asl.), Makassar. During the following planting season, the M2 generation plant was examined in Enrekang District (650 m asl.), South Sulawesi, Indonesia. Based on the early heading and a larger number of panicles, the 18 PB-A and one PB-C M3 line were selected from a total of 404 M2 survival plants. The selected lines and control were grouped into seven clusters based on the quantitative phenotypic traits, indicating the existence of genetic variability. The plant yield was significantly correlated with plant height, the number of tillers, the number of panicles, as well as grain weight per panicle, which showed that these traits are good criteria for selection.
SUSPEN DOME: AN EVALUATION WITH CFRP CABLES

This study investigated the feasibility of using CFRP cable as tension cables in suspen domes in view of the fact that suspen domes have been made with steel cables as its cable-strut system for centuries due to its availability. Indisputably, CFRP cables have become the material of choice in the 21 century for its efficiency and innovative design in bridge works. However, the application of CFRP cables to other cable structures has been limited. The need for its application to other cable structures is required in order to acquire more knowledge about its behavioral patterns. This paper gives preliminary findings of a successfully designed and constructed suspen dome prototype which comprehensively deepens the understanding of CFRP cable performance as a cable-strut system in a suspen dome. Results show that with its high stiffness, low weight and high strength, CFRP has proven to be a technically efficient and adequately strengthening material for structurally improving the adequacy of a suspen dome.
Preparation and characteristics of polyurethane made with polyhydric alcohol‐liquefied rice husk

The limited availability of fossil resource is causing the urgent need to get renewable chemicals. Solvent liquefaction can convert rice husk into bio-based chemicals. Rice husk was liquefied in polyhydric alcohol catalyzed by sulfuric acid under atmospheric pressure. The viscosity, residue content, and weight average molecular weight (Mw) of liquefied rice husk were 3089 cps, 23.6% and 4100, respectively. Prolonging the liquefaction time decreased the residue content and increased the average molecular weight. Polyurethane (PU) foams were successfully prepared from the liquefied rice husk with different molar ratios of NCO to OH (NCO/OH). The mechanical properties of PU foams showed that the compressive strength in the vertical direction is higher than that in the horizontal direction. With Increase of the NCO/OH molar ratio from 1.0 to 2.0, compressive strength in the vertical direction of PU foams increased from 70.6 to 114.7 kPa at 10% strain. Thermal analysis results showed that thermal stability of liquefied rice huskbased PU resins was better than that of fossiland liquefied woodbased PU resins. Increasing the NCO/OH molar ratio and inorganic residue of rice husk can help to increase thermal stability. VC 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 135, 45910.
The Ins and Outs of Investing in Illiquid Assets

Investments in illiquid asset classes have become more common in recent decades. According to Ang (2014) the share of illiquid asset classes held by pension funds has risen from 5% in 1995 to 20% in 2011. There are a number of reasons for this increasing popularity including the perception that (expected) returns are higher as well as that they offer greater diversification potential. It is however not always clear what the required extra return or diversification benefits for the illiquidity should be. Additionally there are numerous reasons for illiquidity each with their own challenges.
Efficient laser-driven proton and bremsstrahlung generation from cluster-assembled foam targets

The interaction between intense 30 fs laser pulses and foam-coated 1.5 μm-thick Al foils in the relativistic regime (up to 5 × 1020 W cm−2) is studied to optimize the laser energy conversion into laser-accelerated protons. A significant enhancement is observed for foam targets in terms of proton cut-off energy (18.5 MeV) and number of protons above 4.7 MeV (4 × 109 protons/shot) with respect to uncoated foils (9.5 MeV, 1 × 109 protons/shot), together with a sixfold increase in the bremsstrahlung yield. This enhancement is attributed to increased laser absorption and electron generation in the foam meso- and nanostructure.
A mechanical amplifier based high-finesse fiber-optic Fabry–Perot interferometric sensor for the measurement of static magnetic field

A high-finesse fiber-optic extrinsic Fabry–Perot interferometer (EFPI)-based sensor for the measurement of static magnetic fields is proposed and experimentally demonstrated. The high-finesse EFPI is composed of two aligned fiber ends, each of which has a micro-lens mirror. The high-finesse EFPI is mounted on a specially designed mechanical amplification structure which is driven by a TbDyFe rod. Under the applied bias magnetic field, the TbDyFe rod works in the linear region, and its length changes with the change of the magnetic field strength. The mechanical amplification structure amplifies the elongation of the TbDyFe rod in the magnetic field, thus changing the optical cavity length of the high-finesse fiber-optic EFPI. The magnetic field strength can be obtained by measuring the spectral resonance wavelength. Experimental results show that the wavelength sensitivity with the applied magnetic field is 0.218 nm μT−1, the magnetic field resolution is 4.59 nT, and the magnification of the mechanical amplifier is 5.66 times.
A semi-supervised fault diagnosis method for axial piston pump bearings based on DCGAN

Recently, deep learning has developed rapidly in the fault diagnosis technology of axial piston pumps. However, when the training data is scarce and the label information is insufficient, many traditional intelligent fault diagnosis models are invalid. To solve these problems, an intelligent fault diagnosis method for axial piston pumps is proposed based on deep convolutional generative adversarial network (DCGAN). Firstly, the continuous wavelet transform (CWT) and DCGAN are designed to enhance the fault features and expand dataset, respectively. Secondly, according to the number of labeled samples, DCGAN and semi-supervised GAN (SGAN) are used to extract the deep features of the image domain. Finally, the clustering algorithm is used to classify the extracted features to realize the fault diagnosis of the axial piston pump bearing. To verify the feasibility of the proposed method, experimental investigation and public dataset are adopted. When the evaluation indicators of the clustering results are close to 1, the proposed method shows the advantages of high diagnostic accuracy, superior generalization ability and excellent anti-noise ability.

High temperature magnetic characterisation of structural steels using Epstein frame

Electromagnetic non-destructive testing techniques provide an attractive solution to the problem of monitoring microstructural changes in steels undergoing heat treatment as they are non-contact, have a short response time and are relatively inexpensive. However, to take full advantage of these techniques it is necessary to be able accurately measure the magnetisation characteristics of the materials of interest at temperatures up to the Curie point. This paper details the development of a novel high temperature Epstein frame for installation in a furnace with the design informed and results validated by finite element modelling. Hysteresis loop characteristics are successfully measured for a dual phase steel up to the Curie point for heating and cooling. Results show the developed system has the potential to provide valuable data to inform online electromagnetic monitoring systems.
