Modeling and Detection of Dynamic Position Sensor Offset Error in PMSM Drives
Authors: Kuruppu Sandun , Abeyratne Sunil , Hettiarachchi Sandun
Published: April 2023

 Rotor position information obtained through a position sensor is crucial for proper field-oriented control (FOC) of permanent magnet synchronous machine based high dynamic energy conversion applications. In applications such as transportation and industrial, PMSM energy conversion systems are subjected to harsh environmental conditions such as vibration, shock, and thermal shock causing mechanical interfaces holding positions sensors to fail, introducing error to the position measurement. A dynamic position sensor offset error (DPSOE), being such a failure mode has the potential to degrade system torque output or more adversely, reverse machine torque output that may cause catastrophic outcomes. This paper evaluates different DPSOE scenarios, presents an approach to model the failure mode for analysis and proposes two novel and robust DPSOE detection methods for PMSM drive systems. The proposed detection methods are analytically proven and supported by simulation and experimental results under multiple operating conditions proving robustness. 
Blockage and RIS Cooperative Joint Beamforming for mmWave MIMO Systems
Authors: Sarker Md Abdul Latif , Baek Minjin , Seog Han Dong
Published: April 2023

The revised version has been submitted to the IEEE Transactions on Vehicular Technology.

 A reconfigurable intelligent surface (RIS) is a kind of metasurface that provides an adaptable way of controlling the propagation of radio signals in wireless systems, allowing for improved coverage and system efficiency. Instead of the traditional RIS-assisted single-to-multiple reflection channel, we present a time-variant location-based hybrid reflection channel(TL-HRC) model in this paper. The designed TL-HRC model can easily tune a cooperative situation between the mobile blockage and RIS in millimeter wave massive multiple-input and multiple-output systems and satisfactorily scale a high received power gain. Based on the designed TL-HRC model, we establish a joint active and passive beamforming problem for the weighted sum rate maximization and propose an alternative optimization with a RIS element selection (AO-RES) algorithm to tackle the challenging high dimensional coupled parameters. Through simulation experiments the effectiveness of the proposed TL-HRC-based AO-RES algorithm is validated in terms of the weighted sum rate with the case of perfect channel state information.

Published: April 2023

Image registration is a technique of matching and superimposing of features, which can be better applied to high-level vision tasks. However, high-level vision tasks often pay more attention to analysis of target areas. In summary, we rethink the collaborative relationship between image registration and high-level vision tasks, and propose a local registration strategy for constructing a robust adaptive attention gauge fields, and construct robust adaptive attention gauge fields to register images focus more on important target areas. In order to improve the robustness and timeliness of the algorithm for feature matching of target areas in complex environments, we propose a robust adaptive probability distribution(RA), and construct robust adaptive mixed model expectation maximum attention(RAMM-EMA). In order to make robust adaptive parameters to reach the global optimum in deep learning, we designed a simulated annealing method to optimize the robust adaptive parameters during training. In order to focus on important regions in the image as much as possible, propose a feature fusion map with weak boundaries and probabilistic properties, called Robust Adaptive Attention Gauge Fields(RAA-Gauge Fields). High-level vision tasks experiments on image fusion, object delect and 3D-reconstruction, the method presented in this paper is the most helpful, and registration effect of the target areas perform best under more extreme conditions. 
Estimating Fractal Dimensions in an Evolving System
Authors: Kak Subhash
Published: April 2023

It is shown that fractal dimensions may be reasonably estimated in an evolving system when further information is not available by considering the growth in the number of cells in two steps. This may be of use in the estimation of the dimensionality of metamaterials as well as in other natural phenomena. In contrast to algorithm-generated patterns for which a time step is well defined, natural systems evolve in an active space that leads one to the optimal information dimension of e, and this provides a novel perspective on self-similar behavior in natural systems.
Simulation Study of An Interleaved Flyback Converter for Micro Grid Systems Operating in the CCM Mode
Authors: Salihmuhsin Metin
Published: April 2023

 This paper presents a design and an implementation of an isolated grid connected micro inverter system that is based on an interleaved flyback topology. The developed system gets input from a 250 W PV panel, converts the dc energy into ac and connects it to the grid. This work covers the simulation aspect of developing the above mentioned system where extensive simulations are performed in order to find and optimize values of desired parameters and simulate the overall system. The CCM (Continues Conduction Mode) of operation for the flyback converter is preferred as it generates considerably less amount of the current ripple at converter output when compared to DCM operation and less amount of power loss. A feedback loop with a PI controller is incorporated into the design in order to properly stabilize the system. Simulation results demonstrated that the developed system generates sinusoidal voltage and current signals of 50 Hz in frequency with desired amplitudes at the output of the system. Connection of generated ac waveforms to the grid is accomplished by means of a PLL block. THD of the grid current is found as 11.57% due to spikes at zero crossings.

Published: April 2023

Land-reflected signals from a geosynchronous communication satellite broadcasting in P-band (367.5 MHz) were captured in low Earth orbit using a simple dipole antenna. A delay-Doppler map (DDM) was generated through autocorrelation. Estimates of the specular point delay were obtained from the lag of the second peak in the DDM with a bias of 239.4 m and a standard deviation of 44 m (12 m over a frozen lake) with respect to a predicted orbit model. Relative magnitudes of the first and second DDM peaks fell within the range of values predicted using dielectric models for the frozen ground and lake. Lastly, retrievals of surface reflectivity were generated using a range of realistic values for the transmitter link budget G/T, these also fell within the range of possible values for the antenna gain pattern. Given the lack of calibration and the large uncertainties in the receiver orbit and attitude, this agreement is sufficient to conclude a successful demonstration of the fundamental principle of single-antenna reflectometry in P-band. P-band reflectometry may offer a new approach to remote sensing of sub-canopy and root-zone soil moisture.

Analytical Model of 3D Helical Solenoids, for Efficient Computation of Dynamic EM Fields, Complex Inductance, and Radiation Resistance
Authors: Zadehgol Ata
Published: April 2023

We use the dynamic Green's function to produce a frequency-dependent magnetic vector potential $\vec{A}(\omega)$ and derive expressions for the efficient (accurate and fast) computation of cylindrical components of the magnetic flux density vector $\vec{B}(\omega)$ as a function of the solenoid's geometric and material parameters. $\vec{A}(\omega)$ may be used to efficiently compute the frequency-dependent flux linkage $\Phi(\omega)$, the complex inductance $L(\omega)$, and the radiation patterns of the solenoid anywhere in space including both near-field and far-field regions, excluding the (source) regions of conducting wire. Additionally, we propose the complex calibration coefficient $\chi(\omega)$ to account for the finite-radius conductor.

Several numerical examples are provided to validate the proposed helical model against the superposition of circular loops. The proposed model is demonstrated for a wide range of applications across the spectrum from 60 Hz to 170 GHz, representing low-frequency power systems to high-frequency mm-wave communication systems. A plan is being developed for experimental validation of the model.

On Calibration of Mobile Low-cost Sensors for Urban Air Quality Monitoring
Authors: V Narayana Mannam , Jalihal Devendra , Nagendra S M Shiva , Giri Aswin
Published: April 2023

In vehicular mobility applications, sensor devices are exposed to rapidly varying concentrations of pollutants. Therefore, more than a conventional data set containing features such as sensor output, temperature and humidity is required to calibrate mobile sensors. We propose a new data set having additional features to address possible error sources encountered in vehicular-mobility LCS applications. We show that the proposed data set is a better choice for calibrating mobile LCS devices when compared to the conventional data set. Further, we propose and investigate two different tandem configurations involving a two-phase calibration approach to improve the calibration accuracy of mobile sensors. The calibration is done with real-time data obtained from an LCS device, SensurAir, which we developed and deployed in Chennai, India.

Published: April 2023

Microplastics from sewage and wastewater treatment facilities can be discharged into rivers and oceans, and the treatment facilities themselves can be a point source of microplastic pollution. The microplastic detection status and methods were compared in Miwon, Cheongju, Jecheon, and Chungju sewage treatment facilities in Chungcheongbuk-do. Samples were collected from the inlet, filtration facility, and discharge of Miwon Sewage Treatment Facility, a Porous Substrate Bioreactor (PSBR) construction corporation. Additionally, the inlet, first settling tank, final settling tank and outlet samples were taken from three sewage treatment facilities (Cheongju, Jecheon, and Chungju), which use bioreactor transformation processes. In the results, raw water showed a range of 232-1,510 pieces/L, and effluent water showed a range of 0.7-6.7 pieces/L. All four sewage treatment facilities showed high treatment efficiency of 98.5-99.9%. The treatment processes showed high removal efficiency in the order of CNR (97.0%) > PSBR (95.9%) > NPR (91.5%) > SMART3 (70.3%). As a study was conducted on only one sewage treatment facility for each process, additional research is necessary.

Authors: Aamri Hasna , Kaouani D. , Elqadiry R. , Nassih H. , Bourrahouat A. , Sab I. Ait
Published: April 2023

Background: Glomerulonephritis (GN) is a rare kidney disease that causes significant morbidity and mortality. They are frequently difficult to treat, and in some cases, no treatment is available, and they can progress to chronic kidney disease (CKD) and end stage renal disease (ESKD). Kidney biopsy is the preferred diagnostic method because it helps determine the precise specific diagnosis, assesses the level of disease activity and severity, and thus aids in proper therapy and prognosis prediction. Methods: Retrospective review of 40 children under the age of 15 with GN diagnosed between 2019 and 2022. Nephrotic syndrome, sub-nephrotic proteinuria, nephrotic syndrome (NS) with acute kidney injury (AKI), subnephrotic proteinuria plus AKI, isolated hematuria, and unexplained renal impairment were the six clinical syndromes for which a kidney biopsy was performed in 25 patients. Hospital admission records, progression notes, and outpatient follow up were used to collect data. Results: Acute glomerulonephritis (AGN) with nephritic syndrome (NS) affected 53% of the patients. Patients with AGN-NS were more likely to develop hypertension (48.0% vs. 15.7%) and acute renal damage (32% vs. 10%). 48% of the patients had Acute Postinfectious Glomerulonephritis. 5% of the patients had membranoproliferative glomerulonephritis. 2.5% of patients with ANCA-negative rapidly progressive glomerulonephritis had extramembranous glomerulonephritis, and 2.5% had extracapillary glomerulonephritis. The kidneys of 24 people were biopsied. The most common reason for a kidney biopsy was rapidly progressing glomerulonephritis. Conclusion: Acute postinfectious glomerulonephritis has been the most common glomerulonephritis in our study over the last three years in our Marrakech department. It manifested as a rapidly progressive glomerulonephritis in twelve of the cases.

Introduction: Viral hepatitis is a public health threat that has long been underestimated. This infectious disease is the seventh cause of death in the world and even ahead of HIV in terms of epidemiological prevalence. Objective: highlight the seroprevalence of hepatitis B and C viral infections in patients seen in the medical analysis and pathology laboratory department of the Mali hospital. Method: This is a prospective and retrospective study that took place from July 2021 to August 2022. This study included 1540 samples from eligible patients with HBsAg, Anti HBe IgG Antibody, Anti HBc Antibody, HBe Ag, Antibody Anti HBs and/or anti-HCV antibodies. Results: These different methodologies allowed us to have the results of 1540 samples concerning this study. The female sex was more represented with 62.92% compared to the male sex or 37.08%. The HBSAg was mainly found positive in the male sex with 5.45%. The average age was 38 ± 17 years with extremes ranging from 2 to 92 years. The age group 21-39 years was the most represented with 47.47% and the most affected by the positivity of the HBSAg with 5.65%. 64.03% of our patients were married and also with increasing positivity for HBS Ag and anti-HCV Ac with 5.91% and 0.91% respectively. The seroprevalence of HBV, HCV and HVB/HCV co-infection were 10.06, 0.9% and 0.84% respectively. Conclusion: Hepatitis B remains largely unknown to the general public but also to many medico-social actors. This lack of knowledge represents a major obstacle to prevention and screening. It also has as a corollary the stigmatization of people who are affected, in romantic encounters or at work in particular. A high seroprevalence of HBsAg obtained indicates the spread of hepatitis B in the Malian population.

The Schiff base ligand has been synthesized by the reaction of ethanolic solution of benzaldehyde and 2,4-dinitrophenylhydrazine. The corresponding metal complexes were obtained by refluxing the chlorides of Co(II) and Ni(II) with the prepared Schiff base in an ethanolic medium. The Schiff base and its metal complexes were established and analyzed by FT-IR, solubility test, melting point/decomposition temperature and conductivity measurement. The melting point of the Schiff base was found to be 157C and decomposition temperature of Co(II) and Ni(II) complexes were found to be 167°C and 174°C respectively. Molar conductance values of Co(II) and Ni(II) complexes are 1.31 and 2.04 µS/cm respectively. The solubility test carried out showed that the complexes are soluble in most organic solvents and insoluble in water. The antibacterial activity test of the ligand and metal complexes showed that the metal complexes were found to be active against the organism tested while the ligand was inactive.

The metal concentrations were determined using Atomic Absorption Spectrometry technique. Optimum percentage removal of the metal ions was achieved at pH 6.26 for Ni2+ (89.40 % for ROSE and 97.60 % for ROSEDS) and pH 7.57 for Pb2+ (80.10 % for ROSE and 82.56 % for ROSEDS). Optimum adsorption capacities of ROSE and ROSEDS for Ni2+ were 6.30 mg/g and 7.10 mg/g respectively; while for Pb2+ ions, values obtained for ROSE and ROSEDS were 5.87 mg/g and 6.34 mg/g respectively. Varying adsorbents dosage at fixed metals ion concentration yielded optimum percentage removal of 89.90 % and 97.90 % for Ni2+, while 86.85 % and 90.80 % for Pb2+, using ROSE and ROSEDS, respectively. Adsorption capacities of the adsorbents varied inversely with adsorbent dosages. In general, 4-aminophenol modified red onion skin extract (ROSEDS) gave comparatively, better results for the extraction of Ni2+ and Pb2+ ions from aqueous medium; relative to the unmodified red onion skin extract (ROSE). Additionally, extraction of Ni2+ ions gave higher percentage removal values in both adsorbents when compared to extraction of Pb2+ ion under similar conditions. This result has been attributed to differences in their ionic radii. REVIEW ARTICLE | April 4, 2023

The New ligand 5-methyl-2-(2-thienyl)-1,3-oxazole-4-carbaldehyde thiosemicarbazone (HL)(1) was synthesized. This ligand reacted with Co(II) and Ni(II) chloride in ratio 1:2 metal:ligand afforded two complexes, [Co(LH)]Cl2 (2) and [Ni(HL)2]Cl2 (3). The ligand and its metal (II) complexes have been characterized by spectroscopic techniques. The X-ray structural studies revealed that the free ligand exist in thione form and remain as neutral tridentate with NNS donor atoms in the tow complexes beside presence of uncoordinated chloride ions in the cavities of the crystal lattice of the complexes. One of these chlorides in complex (2) is hydrogen bonded to a proton of the amine of the ligand. While in complex (3) the chloride bonded to proton of imine (-N2H) of the ligand and the coordination environment has a distorted octahedral. The oxazole N and S atoms in the two complexes are cis to each other whereas the azomethine N atoms are trans coordinated. The ligand and its metal complexes were tested for their in vitro biological activity against six standard microorganisms: two Gram positive namely Bacillus subtilis and Micrococcus luteus, and one Gram negative bacteria Escherichia coli and three fungi: Saccharomyces cerevisiae (Baker’s yeast), Mucor spec., and Aspergillus niger, at a concentration 100µg/ml.

The objectives of this study are to analyze and find weaknesses in government policies in the field of women's empowerment in realizing gender equality and how to reconstruct the law to realize better Gender Equality. The method used in this study uses an empirical juridical approach supported by a normative approach with the paradigm used by the constructivism paradigm. Results of the research show that the Weaknesses in government policies in the field of women's empowerment in realizing equitable gender equality is that there is still low knowledge and skills (competence) of HR planners in OPD regarding how to prepare PPRG (GAP and GBS), due to weaknesses in regulations in Permendagri No. 67/2011, which has not regulated the obligation of PUG Pojka to organize and provide training to focal points in each SKPD. Therefore, a legal Reconstruction of government policies in the field of Women's Empowerment in realizing a just Gender Equality is needed, namely by following up on regulations that require the implementation of gender mainstreaming in regional development by reconstructing Article 10 of Permendagri No. 67/2011, namely by regulating the obligations of PUG Working Groups to organize and provide training and at the same time providing sanctions for violations of duties by PUG Working Groups.
