Disturbance Decoupling for a Single-Phase Pulse Width Modulation Rectifier Based on an Extended H-Infinity Filter

The growing utilization of single-phase pulse width modulation (PWM) rectifiers in various applications has spurred interest in detecting and monitoring faults in these devices. In particular, voltage and current sensors play a crucial role in the control loop of these rectifiers. However, sensor faults can significantly affect the converter’s performance and availability. This paper introduces a novel and efficient method for detecting and decoupling sensor faults in single-phase PWM rectifiers. The proposed method utilizes residual generation and incorporates an extended filter within the rectifier. Unlike conventional filters, the presented fault detection and isolation (FDI) method effectively eliminates the influence of disturbances on the residual signal. This feature helps prevent false alarms in the monitored system, ensuring reliable fault detection. To evaluate the effectiveness of the approach, hardware-in-the-loop and simulation tests were conducted. The results from these tests provide substantial evidence supporting the efficacy of the proposed method. The hardware-in-the-loop experiments involved real-world implementation, validating the practicality and reliability of the approach. Meanwhile, simulation tests allowed for a comprehensive analysis of system behavior and performance under various fault scenarios. The findings demonstrate the rapid and dependable nature of the proposed method for detecting and decoupling sensor faults in single-phase PWM rectifiers. By effectively mitigating the impact of disturbances on the residual signal, false alarms are minimized, ensuring accurate fault detection. The experimental validation highlights the practical applicability and effectiveness of the proposed approach, making it a valuable contribution to fault detection in single-phase PWM rectifiers.
Muscle Activity Analysis using Higher-Order Tensor Models : Application to Shared Muscle Synergy Identification

Objective: Higher-order tensor decompositions have hardly been used in muscle activity analysis despite the fact that multichannel electromyography (EMG) datasets used in muscle synergy studies naturally present multi-way structure. Here, we seek to discuss and demonstrate the potential of tensor decomposition as a framework to estimate muscle synergies from 3-order EMG tensors constructed by stacking repetitions of multi-channel EMG for several tasks. Methods: We compare the two most common decomposition models – Parallel Factor Analysis (PARAFAC) and Tucker – in muscle synergy extraction from the three main degrees of freedom (DoF) of the wrist using the first Ninapro database. We then utilise the power tensor factorisation to create a novel direct method for shared and task-specific synergy estimation from two biomechanically related tasks by developing a constrained Tucker decomposition method. Our approach is compared with the current standard approach of repetitively applying non-negative matrix factorisation (NMF) to a series of the movements. Results: The results show that the constrained Tucker method successfully identified the shared and task-specific synergies for all 3 DoF tensors directly and it was robust to misassignments with regard to task-repetition information unlike NMF, thanks to exploring the multi-way structure of muscle activity. Conclusions: We showed the potential of tensor factorisations to study and characterise muscle activity and developed a new direct method for shared and task-specific synergy identification with a constrained Tucker decomposition. Significance: We expect that this study will pave the way for the development of muscle activity analysis methods based on higher-order techniques.

Triaxial models description of the low-lying properties in 192Os

Several typical triaxial models have been parallel addressed and applied to describe the energy values and B(E2) transitional rates in the ground band and the γ band for 192Os. It is shown that the different triaxial model presents different triaxial dynamics but each of them can only succeed to explain part of the spectral properties of this nucleus, which indicates that the triaxial shape of 192Os may be more complicated than that reflected by an ideal triaxial model. In addition, the staggering signature in experiments hints that γ-rigid triaxiality should be more or less involved in 192Os.
Quantum Electron-acoustic Envelope Solitons and Their Modulational Instability in a Degenerate Quantum Plasma

The basic features of linear and nonlinear quantum electron-acoustic (QEA) waves in a degenerate quantum plasma (containing non-relativistically degenerate electrons, superthermal or κ-distributed electrons, and stationary ions) are theoretically investigated. The nonlinear Schödinger (NLS) equation is derived by employing the reductive perturbation method. The stationary solitonic solution of the NLS equation is obtained, and examined analytically as well as numerically to identify the basic features of the QEA envelope solitons. It has been found that the effects of the degeneracy and exchange/Bohm potentials of cold electrons, and superthermality of hot electrons significantly modify the basic properties of linear and nonlinear QEA waves. It is observed that the QEA waves are modulationally unstable for k < kc, where kc is the maximum (critical) value of the QEA wave number k below which the QEA waves are modulationally unstable), and that for k < kc the solution of the NLS equation gives rise to the bright envelope solitons, which are found to be localized in both spatial (ξ) and time (τ) axes. It is also observed that as the spectral index κ is increased, the critical value of the wave number (amplitude of the QEA envelope bright solitons) decreases (increases). The implications of our results should be useful in understanding the localized electrostatic perturbation in solid density plasma produced by irradiating metals by intense laser, semiconductor devices, microelectronics, etc.
Modeling Log-linear and Logit Models in Categorical Data Analysis

The association between categorical variables is analyzed using the mutual information approach complied with the multivariate multinomial distributions. Schematic decompositions of mutual information are employed for characterizing log-linear and logit models. A geometric analysis of the conditional mutual information is proposed for selecting indispensable predictors and their interaction effects for constructing log-linear and logit models. The new approach to selecting the most concise logit model also facilitates search for the minimum AIC model with a finite set of predictors. The proposed constructive schemes are illustrated in analyzing a contingency table of data collected in a study on the risk factors of ischemic cerebral stroke.
Bundle block adjustment with ultracamD images

Large blocks of UltraCam D images have been taken over the area of Istanbul. The high accuracy of the digital images together with crossing flight lines allows a reduction of the number of ground control points against the rules of thumb for analogue photos. By simple theory a calibrated digital camera should not show systematic image errors - we do have no problems with film flattening and film deformation. But the bundle adjustments showed the requirement of a self-calibration. Special additional parameters, able to correct the position of the 9 sub-images of the UltraCam D , have been introduced into the used program system BLUH. Block adjustments with different control point configurations and different sets of additional parameters have been investigated. In general there is a clear improvement of the accuracy of independent check points by a block adjustment with self-calibration. Especially with a smaller number of control points the vertical accuracy is quite better with it Against the standard set of 12 additional parameters the set of 32 special parameters for the UltraCam D could not improve the results even if the shape of the systematic image errors is similar for all sets. The dominating effect of the systematic image errors is the radial symmetric component, which must not be caused by the camera geometry. The high accuracy of the digital camera seems to allow a larger control point distance in relation to analogue photos.
The Connection between the Madden-Julian Oscillation and European Weather Regimes and its Modulation by low frequency Forcings

Progress in extended range numerical weather prediction for Europe relies on a correct representation of the large-scale midlatitude circulation which can be described by specific weather regimes for the Atlantic-European region. Therefore, it is important to understand their life cycles and identify processes that are responsible for their favoured occurrence, persistence or transition. Recent studies have shown that convectively active phases of the Madden-Julian Oscillation (MJO) in the tropics impact and control part of the distribution and sequences of the daily weather regimes defined over the North Atlantic-European region. Thereby, El Niño-Southern Oscillation (ENSO), the Pacific-North American teleconnection pattern (PNA), and the strength of the stratospheric polar vortex modulate the background states through which the MJO and its global response patterns propagate during Northern Hemisphere winter. Within this thesis, we here present how the frequency of defined Atlantic-European weather regime occurrences is modulated following an MJO activity. The lagged relationship between active MJO episodes and weather regime occurrences is explored for 37 extended winters from 1979 to present. We examined for unmodulated and modulated background states the potential predictability, focusing separately on the influence of ENSO, PNA and the strength of the stratospheric polar vortex. The results indicate that the lagged relationship between the MJO phases and the weather regimes strongly differs during different states of ENSO, PNA and the stratospheric circulation. Hence, the European response to MJO activity substantially changes with a varying background state. Our findings demonstrate the importance of considering both the MJO activity in its phase and the concurrent low frequency forcings to determine the statistically expected regime frequency due to a MJO event.
Characterization of a New Silk Sericin-Based Hydrogel for Water Retention in Soil

Hydrogel-type absorbent materials are currently a technological alternative for improving water retention in the soil and reducing nutrient loss by leaching and evaporation. This study aimed to evaluate the application of a new hydrogel based on silk sericin (SS) as a water retention material in soil. The morphology of the hydrogel was characterized using Scanning Electron Microscopy (SEM), and its impact on moisture retention in sandy loam soil (SLS) under different levels of matric pressure (MP) was evaluated. Additionally, water content data were collected over time for both SLS and SLS with hydrogel (SLS + H), and the data were used to fit predictive models. The results indicate that the hydrogel had a porous morphology that promoted water retention and soil release. Under a MP of 0.3 bar, the use of the hydrogel increased water retention by 44.70% with respect to that of SLS. The predictive models developed were adequately adjusted to the behavior of the moisture data over time and evidenced the incidence of the absorbent material on the dynamics of the moisture content in the soil. Therefore, these models could be useful for facilitating subsequent simulations or for designing automatic soil moisture control systems oriented to smart farming.
The Impact of Soft Lean Management Practices on Green Innovation the Mediating Role of Absorptive Capacity: An Applied Study in the Manufacturing Sector in Jordan

Purpose: This study aims to investigate the relationship between soft lean practices and green innovation in the presence of absorptive capacity as a mediating construct in the manufacturing sector in Jordan, which is thought to be a knowledge-intensive firm affecting the Jordanian economy. Theoretical Framework: Lean practices are gaining popularity in studies and are also seen as a model for innovation, particularly in knowledge-intensive industries. These procedures have grown to be essential to a company's success, particularly in intricate and rapidly changing business environments. Design/methodology/approach: All manufacturing companies doing business in Jordan make up the sample for this study. This industry was chosen because it is a knowledge-intensive industry that is a global innovation driver, setting it apart from other industrial sectors. 145 department heads, professionals, and knowledgeable employees from this company were randomly chosen to make up the study unit of analysis. The questionnaire's items were created using a review of the literature and all of the construct measures that had been tried and true in earlier research. Findings: The results showed that soft lean practices and absorptive capacity are antecedent to green innovation and confirm that there is a significant and direct relationship between soft lean practices and green innovation, and an indirect relationship with absorptive capacity. Research, Practical & Social implications: The analysis of lean practices' effects on green innovation hasn't received as much attention in the literature currently available on business as it has on the examination of lean practices' relationships with innovation and innovative performance. Few empirical studies have examined the moderating role that absorptive capacity plays in the relationship between soft lean practices and green innovation; however, absorptive capacity has been discussed as an intermediate construct in a few prior studies. Originality/value: The findings offer valuable recommendations to managers for improving companies' absorptive capacity and green innovation. As a result, the current study examines the impact of soft lean practices on green innovation by absorptive capacity in the context of Jordan's manufacturing sector, which is home to some of the country's most successful and influential businesses in the country's knowledge-intensive industry.
(Pseudo)digraphs and Leibniz algebra isomorphisms

This paper studies the link between isomorphic digraphs and isomorphic Leibniz algebras, determining in detail this fact when using (psuedo)digraphs of 2 and 3 vertices associated with Leibniz algebras according to their isomorphism classes. Moreover, we give the complete list with all the combinatorial structures of 3 vertices associated with Leibniz algebras, studying their isomorphism classes. We also compare our results with the current classifications of 2‐ and 3‐dimensional Leibniz algebras. Finally, we introduce and implement the algorithmic procedure used for our goals and devoted to decide if a given combinatorial structure is associated or not with a Leibniz algebra.
Management of grassland/savannas encroached by woody plants in South American Semiarid Chaco: Ecological restoration vs. African grasses introduction

A�������. In Semiarid Chaco, two management approaches for woody plant-encroached grassland/savannas were evaluated: ecological restoration and the African grass introduction. An experiment with five treatments was carried out: 1) reference community (Ref_Eco; a grassland/savanna in good state, used as standard of comparison); 2) grassland/savanna encroached by woody plants (Woody_Encr; the woody state of grassland/ savannas); 3) roller chopping of the encroached ecosystem, followed by grazing suppression and prescribed fire (Roll_Fire; aimed at inducing grassland/savanna ecological restoration); 4) roller chopping of the encroached ecosystem, with instantaneous seeding of Megathyrsus maximus cv. Ga�on Panic and grazing suppression (Roll_Ga�on Panic), and 5) roller chopping of the encroached ecosystem, with instantaneous seeding of Cenchrus ciliaris cv. Buffel Texas and grazing suppression (Roll_Buffel Texas). The last two treatments aimed to obtain new highly productive grassy states for ranching through the introduction of these African grasses. The results suggested that Ref_Eco (average herbaceous biomass [HERB]=7196.9 kg DM/ha) was dominated by shade intolerant and fire tolerant grasses, and it had good soil quality and good utilitarian range condition. Regarding Ref_Eco: a) in Woody_Encr (HERB=2192 kg DM/ha), the vegetation structure, plant composition and the utilitarian range condition were altered, but it still had good soil quality and abundant native grass populations; b) in Rol_Fire (HERB=6591.6 kg DM/ha), both the vegetation structure and good utilitarian range condition were restored, plant composition was not restored and the good soil quality was kept, and c) Roll_Ga�on Panic and Roll_Buffel Texas (HERB=10972.1 and 7450.8 kg DM/ha, respectively) resulted in new grassy states integrated by native and exotic grasses with good utilitarian range condition and good soil quality. In this study case, the ecological restoration of the encroached ecosystems would be both ecologically and productively viable. So, probably the introduction of African grasses to improve ranching was not necessary.
An alternative technique for solving a coupled PDE system in interphase heat transfer

ABSTRACT Recently an accelerated iterative procedure was studied for solving a coupled partial differential equation system in interphase heat transfer to improve some existing iterative procedures in the literature. In that procedure, at each step of the iteration one has to evaluate the derivative of a well-known function at a new point. In this paper, an alternative approach is proposed in which one has to evaluate the derivative only once throughout the procedure. The proposed new iterative scheme also has the same order of convergence and takes lesser number of iterations for certain benchmark problems. An interesting theoretical study on the monotone convergence as well as error estimate of the proposed iterative procedure are provided for continuous as well as discretized problems. The proposed iterative procedure also supplements the existence and uniqueness of the solution in both the cases. A comparative numerical study is also done to demonstrate the efficacy of the proposed scheme.
A C57BL/6J Fancg-KO Mouse Model Generated by CRISPR/Cas9 Partially Captures the Human Phenotype

Fanconi anemia (FA) develops due to a mutation in one of the FANC genes that are involved in the repair of interstrand crosslinks (ICLs). FANCG, a member of the FA core complex, is essential for ICL repair. Previous FANCG-deficient mouse models were generated with drug-based selection cassettes in mixed mice backgrounds, leading to a disparity in the interpretation of genotype-related phenotype. We created a Fancg-KO (KO) mouse model using CRISPR/Cas9 to exclude these confounders. The entire Fancg locus was targeted and maintained on the immunological well-characterized C57BL/6J background. The intercrossing of heterozygous mice resulted in sub-Mendelian numbers of homozygous mice, suggesting the loss of FANCG can be embryonically lethal. KO mice displayed infertility and hypogonadism, but no other developmental problems. Bone marrow analysis revealed a defect in various hematopoietic stem and progenitor subsets with a bias towards myelopoiesis. Cell lines derived from Fancg-KO mice were hypersensitive to the crosslinking agents cisplatin and Mitomycin C, and Fancg-KO mouse embryonic fibroblasts (MEFs) displayed increased γ-H2AX upon cisplatin treatment. The reconstitution of these MEFs with Fancg cDNA corrected for the ICL hypersensitivity. This project provides a new, genetically, and immunologically well-defined Fancg-KO mouse model for further in vivo and in vitro studies on FANCG and ICL repair.

Keynote: Analysis of the results obtained from the application of the two-stage method with calculations of some statically indeterminate trusses

The paper presents results of calculations of forces in members of selected types of statically indeterminate trusses carried out by application of the two-stage method of computations of such structural systems. The method makes possible to do the simple and approximate calculations of the complex trusses in two stages, in each of which is calculated a statically determinate truss being an appropriate counterpart of the basic form of the statically indeterminate truss structure. Systems of the statically determinate trusses considered in the both stages are defined by cancelation of members, number of which is equal to the statically indeterminacy of the basic truss. In the paper are presented outcomes obtained in the two-stage method applied for two different shapes of trusses and carried out for various ways of removing of appropriate members from the basic trusses. The results are compared with outcomes gained due to application of a suitable computer software for computation of the same types of trusses and for the same structural conditions.
Impact of geolocation data on augmented reality usability: A comparative user test

Abstract. While the use of location-based augmented reality (AR) for education has demonstrated benefits on participants’ motivation, engagement, and on their physical activity, geolocation data inaccuracy causes augmented objects to jitter or drift, which is a factor in downgrading user experience. We developed a free and open source web AR application and conducted a comparative user test (n = 54) in order to assess the impact of geolocation data on usability, exploration, and focus. A control group explored biodiversity in nature using the system in combination with embedded GNSS data, and an experimental group used an external module for RTK data. During the test, eye tracking data, geolocated traces, and in-app user-triggered events were recorded. Participants answered usability questionnaires (SUS, UEQ, HARUS). We found that the geolocation data the RTK group was exposed to was less accurate in average than that of the control group. The RTK group reported lower usability scores on all scales, of which 5 out of 9 were significant, indicating that inaccurate data negatively predicts usability. The GNSS group walked more than the RTK group, indicating a partial effect on exploration. We found no significant effect on interaction time with the screen, indicating no specific relation between data accuracy and focus. While RTK data did not allow us to better the usability of location-based AR interfaces, results allow us to assess our system’s overall usability as excellent, and to define optimal operating conditions for future use with pupils.
