A Common-Mode Voltage Elimination Method With Active Neutral Point Voltage Balancing Control for Three-Level T-Type Inverter

Nowadays, the three-level T-type inverters (3LT2Is) are widely employed in applications with high-performance requirements. The 3LT2Is commonly suffer from neutral point voltage (NPV) unbalance and common-mode voltage (CMV) variation. The medium vector pulse width modulation (MVPWM), which generates the reference voltage using medium and V0[OOO] zero voltage vectors, eliminates the CMV variation in 3LT2Is. However, it cannot keep the NPV balance, negatively affecting power quality. This article proposes a hybrid method to simultaneously eliminate CMV variation and guarantee the NPV balance without topological change or extra hardware. The proposed method uses MVPWM when NPV is balanced, eliminating CMV variation. If NPV goes unbalanced, it utilizes novel high/low triangle PWM (H/LPWM) and MVPWM in a hybrid manner to balance the NPV. The H/LPWM, similar to MVPWM, synthesizes voltage using medium and V0[OOO] voltage vectors to maintain the CMV elimination advantage during the NPV balancing process. However, the difference between H/LPWMs and MVPWM switching patterns adjusts the average neutral point current to balance the NPV. Noteworthy that the proposed method provides NPV balancing ability for the entire power factor range. As a result, it is usable for various applications of 3LT2I, such as photovoltaic inverters and motor drives. The proposed method is carrier-based, which reduces the execution time and simplifies the practical implementation. The simulation study and experimental evaluation have been accomplished, and their results demonstrate the effectiveness of the proposed method.

Low frequency polarization observations of the galactic radio emission

Multifrequency polarization observations of a number of regions of the Galaxy in the frequency range 200-1250 MHz have been carried out. The area of enhanced linear polarization at meter wavelengths around α1950=4h30m, δ1950=61° (l=146°47′,b=9°03′) reveals a nonmonotonic, oscillating spectrum of the polarized brightness temperature. On the contrary, the region of the North Celestial Pole (l=123°,b=27°24′) has practically monotonic spectrum. The possible reasons for this difference are discussed.
Input control and its signalling effects for complementors' intention to join digital platforms

Existing information systems (IS) research on platform control has largely focused on examining how input control (i.e., the mechanisms used to control platform access) affects complementors' intentions and behaviours after their decision to join a digital platform. Yet, our understanding of how input control is perceived before this decision and how such perceptions influence prospective complementors' intention to join a platform is still nascent. In this regard, our study views input control as a salient signal that shapes prospective complementors' expected benefits and costs (i.e., their performance and effort expectancy), and ultimately their decision to join a digital platform. Drawing on signalling theory and the antecedent‐benefit‐cost (ABC) framework, we conducted a randomized online experiment in the context of donation‐based crowdfunding. The experiment results offer empirical support for this view by showing that input control has distinct and complex signalling effects for prospective complementors. In particular, our findings reveal curvilinear and competing signalling effects, with perceived input control increasing both performance expectancy (at a decreasing rate) and effort expectancy (at an increasing rate). Also, we find that performance expectancy linearly increases prospective complementors' intention to join a platform, whereas effort expectancy linearly decreases their intention to do so. These findings imply that the overall relationship between perceived input control and intention to join follows an inverted U‐shape curve, which means that neither a low nor a high, but a moderate degree of perceived input control maximizes prospective complementors' intention to join. In sum, the results of our study provide novel and important insights into the signalling role that perceived input control plays in shaping prospective complementors' decision to join a digital platform.
novel approach for underpreparation protocol in dental implant with low bone quality depending on hounsfield unit presurgically

Objective: The purpose of this research was to adapt a normal or undersized implant preparation protocol for different bone densities depending on the density measure (Implant stability quotient ISQ, Newton centimeter NCM) and from Cone Beam Computed Tomography reading pre-surgically. To eliminate the need for practice and experience in inserting implants in poor bone quality areas to enhance implant primary stability and survival rate. Material and methods: Fifty-nine patients were selected for inclusion in the study. A total of fifty-nine implants were placed. Insertion torque data were recorded, resonance frequency analysis measurements were taken at first stage surgery, and Hounsfield Unit HU was assessed before surgery and kept hidden to prevent bias. The implant preparation protocol divided the patients into two groups whether standard or undersized, which was determined according to the tactile sensation of the operator. Depending on primary stability measures (ISQ, NCM) samples were divided into 4 subgroups. Finally, HU measurements were taken from subgroups with high stability measures to assess whether to do a standard or underprepared surgical preparation. Result: the result showed a positive and strong correlation with a high significance between ISQ, HU, and insertion torque.

A new modulator for digital RF power amplifiers utilizing a wavetable approach

This paper presents for the first time a wavetable-based coding scheme to generate a high-speed binary input signal for digital RF power amplifiers. The approach maximizes the utilization of the time domain handling capabilities of the pulse forming circuit. Key features are a greatly improved output spectrum purity in comparison with common digital modulators, the ability to adjust the modulator to any given pulse forming hardware and a built-in signal correction option that comes without additional computational cost. To give a first impression on the modulators behavior and its possibilities to adapt to different hardware constraints, simulations are carried out for different parameter variations and for different baseband bandwidths. Furthermore, the proposed concept is emulated with an arbitrary waveform generator to gather additional measurement data. For a 5 MHz wideband code division multiple access (WCDMA) signal (6.5 dB peak-to-average power ratio) at 900 MHz, an error vector magnitude (EVM) of 0.26% and better than >58 dB adjacent channel leakage ratio (ACLR) were recorded. To the authors’ knowledge, these are the best values achieved so far for a single-bit coding scheme without digital predistortion that still maintains maximum power coding efficiency.
A Review of the Use of Conditional Likelihood in Capture‐Recapture Experiments

Nous présentons une perspective moderne de l'approche par vraisemblances conditionnelles de l'analyse des expériences de capture‐recapture. Nous montrons que ces vraisemblances conditionnelles relèvent d'un modèle linéaire généralisé, ce qui permet l'application des nombreuses méthodes élaborées dans ce cadre. Pour replacer ces applications dans leur contexte, nous passons en revue quelques‐unes des approches existantes dans les modèles de capture‐recapture avec probabilités de capture hétérogènes au sein de populations fermées. Nous décrivons, en particulier, l'utilisation de modèles de mélange paramétriques et non paramétriques, et examinons de façon plus détaillée le cas où les probabilités de capture sont fonction de covariables.

Modeling of Hexavalent Chromium Removal with Hydrophobically Modified Cellulose Nanofibers

Cellulose nanofibers (CNF) are sustainable nanomaterials, obtained by the mechanical disintegration of cellulose, whose properties make them an interesting adsorbent material due to their high specific area and active groups. CNF are easily functionalized to optimize the performance for different uses. The hypothesis of this work is that hydrophobization can be used to improve their ability as adsorbents. Therefore, hydrophobic CNF was applied to adsorb hexavalent chromium from wastewater. CNF was synthetized by TEMPO-mediated oxidation, followed by mechanical disintegration. Hydrophobization was performed using methyl trimetoxysilane (MTMS) as a hydrophobic coating agent. The adsorption treatment of hexavalent chromium with hydrophobic CNF was optimized by studying the influence of contact time, MTMS dosage (0–3 mmol·g−1 CNF), initial pH of the wastewater (3–9), initial chromium concentration (0.10–50 mg·L−1), and adsorbent dosage (250–1000 mg CNF·L−1). Furthermore, the corresponding adsorption mechanism was identified. Complete adsorption of hexavalent chromium was achieved with CNF hydrophobized with 1.5 mmol MTMS·g−1 CNF with the faster adsorption kinetic, which proved the initial hypothesis that hydrophobic CNF improves the adsorption capacity of hydrophilic CNF. The optimal adsorption conditions were pH 3 and the adsorbent dosage was over 500 mg·L−1. The maximum removal was found for the initial concentrations of hexavalent chromium below 1 mg·L−1 and a maximum adsorption capacity of 70.38 mg·g−1 was achieved. The kinetic study revealed that pseudo-second order kinetics was the best fitting model at a low concentration while the intraparticle diffusion model fit better for higher concentrations, describing a multi-step mechanism of hexavalent chromium onto the adsorbent surface. The Freundlich isotherm was the best adjustment model.
On the Thermochemical Transition Depression of Cellulose Acetate Composite Membranes

Gallic acid (GA) and quercetin (QU) are two important bioactive molecules with increased biomedical interest. Cellulose acetate (CA) is a polymer derived from cellulose and is used in various applications. In this work, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) were used to study the thermal behavior of electrospun CA membranes loaded with quercetin or gallic acid. It was found that gallic acid and quercetin depress the thermochemical transition (simultaneous softening and decomposition) of CA, in a mechanism similar to that of the glass transition depression of amorphous polymers by plasticizers. The extensive hydrogen bonding, besides the well-known effect of constraining polymer’s softening by keeping macromolecules close to each other, has a secondary effect on the thermochemical transition, i.e., it weakens chemical bonds and, inevitably, facilitates decomposition. This second effect of hydrogen bonding can provide an explanation for an unexpected observation of this study: CA membranes loaded with quercetin or gallic acid soften at lower temperatures; however, at the same time, they decompose to a higher extent than pure CA. Besides optimization of CA processing, the fundamental understanding of the thermochemical transition depression could lead to the design of more sustainable processes for biomass recycling and conversion.
Informalität im regionalen Wachstumsprozess. Einblick in eine „Black Box“ der Planungspraxis am Beispiel Luxemburgs

This paper deals with the management of settlement growth in the Grand Duchy of Luxembourg from the perspective of informality. Luxembourg is subject to high demographic and economic growth pressures across all parts of the country (capital, old-industrialized South, rural North), which strongly challenges the current planning system. At the same time, there is no formal regional planning, apart from approaches of inter-municipal cooperation, which are mainly voluntary in nature. Drawing on empirical case studies in two high-growth municipalities (Junglinster, Schuttrange), the paper outlines planning decisions in the institutional triangle between municipality, state and private institutions. Informality serves here not only to compensate for a lack of planning control, but also to deal with the country’s complex legal framework conditions. The vital interests of landowners come into play informally as well: since parts of the country’s wealth emerge from the valorization of property, speculative interests are immanent, and thus block development processes. In this context, the paper addresses elements of a regional growth management that could close the gap that exists between state planning and municipal autonomy.
A Wideband Circularly Polarized Dielectric Patch Antenna With a Modified Air Cavity for Wi-Fi 6 and Wi-Fi 6E Applications

In this letter, a novel wideband circularly polarized (CP) dielectric patch antenna (DPA) featuring low profile and relatively high gain property is investigated for Wi-Fi 6 and Wi-Fi 6E applications. Multiple modes of the feeding structure are excited which produces a wide impedance bandwidth (IBW). The introduction of FR4 branches in the air cavity helps to achieve a wider IBW of 48.3% (4.63–7.58 GHz). The E-field inside the air cavity acquires perturbation from the coupling of two dielectric patches (DP), which contributes to obtaining better CP performance. It can help achieve a wide axial ratio bandwidth of 35.3% ranging from 5.15 to 7.36 GHz for the proposed DPA. As the upper dielectric patch works as a director, a measured peak gain is increased to 8.47 dBic. Based on the multilayer PCB structure, the high permittivity dielectric patches loaded are packaged inside the FR4 substrates and fixed by branches. Therefore, a low-profile DPA with a height of 0.13 λ0 is obtained and exhibits self-packaging for DP elements.
Nitrogen availability and plant–plant interactions drive leaf silicon concentration in wheat genotypes

Abstract Estimating plasticity of leaf silicon (Si) in response to abiotic and biotic factors underpins our comprehension of plant defences and stress resistance in natural and agroecosystems. However, how nitrogen (N) addition and intraspecific plant–plant interactions affect Si concentration remains unclear. We grew 19 durum wheat genotypes (Triticum turgidum ssp. durum) in pots, either alone or in intra‐ or intergenotypic cultures of two individuals, and with or without N. Above‐ground biomass, plant height and leaf [Si] were quantified at the beginning of the flowering stage. Nitrogen addition decreased leaf [Si] for most genotypes, proportionally to the biomass increase. Si plasticity to plant–plant interactions varied significantly among genotypes, with both increases and decreases in leaf [Si] when mixed with a neighbour, regardless of the mixture type (intra‐/intergenotype). Besides, increased leaf [Si] in response to plant–plant interactions was associated with increased plant height. Our results suggest the occurrence of both facilitation and competition for Si uptake from the rhizosphere in wheat mixtures. Future research should identify which leaf and root traits characterise facilitating neighbours for Si acquisition. We also show that Si could be involved in height gain in response to intraspecific competition, possibly for increasing light capture. This important finding opens up new research directions on Si and plant–plant interactions in both natural ecosystems and agroecosystems. More generally, our results stress the need to explore leaf Si plasticity in responses to both abiotic and biotic factors to understand plant stress resistance.

EVOLVEMENT AND RECENT RESEARCH IN PARAMETRIC REPRESENTATIONS OF SPEECH FEATURES FOR AUTOMATIC SPEAKER RECOGNITION

Speech feature extraction is the most important step in any Automatic speaker recognition system. In the last 60 years a lot of research has gone into parametric representation of these speech features. Several techniques have evolved one after the other in order to defeat the shortcomings of the previous one. Yet Automatic Speaker Recognition still remains a challenge mainly due to variations in speaker's vocal tract with time and health, varying environmental conditions, variations in the behavior and quality of speech recorders etc. Although Mel Frequency Cepstral Coefficients (MFCC) has become a standard for speaker recognition, the conventional MFCC has a poor recognition in presence of noise. In this paper MFCC technique was used for Automatic Speaker recognition in case of a slightly noisy environment. In this experiment a VQ codebook was created by clustering the training features of 9 speakers. This data was stored in a speaker database. Here the K means algorithm was used for clustering. A distortion measure based on the minimum Euclidean distance was used for speaker recognition. The failure rate of speaker recognition was found to be 20%. Matlab-7.10. 0 was used for this study. This paper also presents an overview of the techniques that have been used for parametric representation of speech features and the modifications that took place to enhance their capabilities. The paper also discusses the most modern techniques, latest research and various modifications that have been proposed in order to enhance the competence of an Automatic Speaker Recognition System as compared to other Biometric systems. Keywords—Mel Frequency Cepstral Coefficients (MFCC), Reflection Coefficients (RC), Linear Predictive Coefficients (LPC), Linear Predictive Cepstral Coefficients (LPCC), Perceptual Linear Predictive Cepstral Coefficients (PLPCC), Integrated Phoneme Subspace (IPS).
