A robust and efficient method for obtaining the complex modes in inhomogeneously filled waveguides

In this paper, we present a computational simulation of the complex wave propagation in inhomogeneously filled waveguides with lossless and lossy dielectrics. We use a biorthonormal‐basis method as a numerical technique. The behavior of complex modes in different waveguides whose characterization with other methods involves some difficulties is analyzed. © 2003 Wiley Periodicals, Inc.

Managing an Art School in the Covid-19 Pandemic: The Experience of Polish Principals

: Purpose: The article aims to develop a model of managing art school by principals in the period of remote education, forced by the Covid-19 pandemic, in the context of the idea of educational leadership. In the theoretical approach, eclecticism was presented, which, in relation to the educational reality, has the best translation on the quality of the principal’s work. Methodology: The article presents the results of research carried out using the method of online narrative interview, partially guided, which covered all principals of art schools of a different type, from the region of Lublin (exhaustive research). The construction of the model was based on the identification of six categories in art school management. Both qualitative and quantitative research strategy was used in the result analysis procedure. Practical Implications: The conducted research has allowed for the construction of a model of art school management in the period of the global crisis in education caused by the Covid-19 pandemic. The proposed empirical model can form the basis for further analysis in the context of educational leadership and management in crisis and the analysis of functioning schools in correlation with the personal resources of their principals. Moreover, it provides an overview of the situation of arts education, especially the key issues it faces in the post-pandemic reconstruction phase. Originality/value: Reports available in the world scientific literature analysing the functioning of schools during the Covid -19 pandemic do not include and do not refer to art schools. Nor has the method adopted by the authors analysed the functioning of schools during this period in the context of educational leadership.
Oral Antifungal Therapy: Emerging Culprits of Cutaneous Adverse Drug Reactions

Introduction: Antifungals are one of the most widely used drugs in dermatology practice for dermatophytosis. Oral antifungal therapy against superficial dermatophytosis is generally associated with a low incidence of adverse events in an immunocompetent population. However, lately, cutaneous adverse drugs reactions (CADRs) have been reported with varying incidence rates in the patients on oral antifungal therapy with many uncommon morphological patterns. The present, observational study was conducted over a period of 4 months to report the cases which presented with antifungal therapy-associated CADRs. Materials and Methods: It was an observational, prospective study carried out at a tertiary care center in Western India over a period of 4 months. All patients diagnosed with superficial dermatophytic infections (clinically and fungal hyphae seen on 10% potassium hydroxide mount) started on oral antifungal therapy, presenting with cutaneous manifestation other than the primary dermatophytosis were included. The incidence of CADRs due to oral antifungal agents and the percentage of each clinical type of the CADR observed was calculated. Results: The incidence of CADRs due to antifungal drugs was 8.3 per 10,000 patients. In total, 35 cases were reported out of 4,208 cases of dermatophytosis. Terbinafine was the most common causative drug, accounting for nearly 83% of cases, followed by itraconazole for 14% cases, and griseofulvin for 2.8% of cases. Conclusion: The role of systemic antifungals must not be overlooked in any patient with a CADR and should be reported as a trend indicator.
Design and Implementation of 5.8 GHz RF Wireless Power Transfer System

In this paper, we present a 5.8 GHz radio-frequency (RF) wireless power transfer (WPT) system that consists of 64 transmit antennas and 16 receive antennas. Unlike the inductive or resonant coupling-based near-field WPT, RF WPT has a great advantage in powering low-power internet of things (IoT) devices with its capability of long-range wireless power transfer. We also propose a beam scanning algorithm that can effectively transfer the power no matter whether the receiver is located in the radiative near-field zone or far-field zone. The proposed beam scanning algorithm is verified with a real-life WPT testbed implemented by ourselves. By experiments, we confirm that the implemented 5.8 GHz RF WPT system is able to transfer 3.67 mW at a distance of 25 meters with the proposed beam scanning algorithm. Moreover, with the proposed beam scanning algorithm, the power transfer efficiency reaches 20.32 % and 0.24 % at distances of 0.5 and 5 meters, respectively, whereas the far-field-only-scanning scheme achieved the transfer efficiencies of 13.45 % and 0.23 % at the same receiver positions. Since the proposed transmit antenna array has the maximum linear dimension of 299.12 mm, the approximate boundary between far-field and radiative near-field is 3.45 meters based on the Fraunhofer distance calculation. The results show that the proposed algorithm can effectively cover radiative near-field region differently from the conventional scanning schemes which are designed under the assumption of the far-field WPT.
E-Pilots: A system to predict hard landing during the approach phase of commercial flights

More than half of all commercial aircraft operation accidents could have been prevented by executing a goaround. Making timely decision to execute a go-around manoeuvre can potentially reduce overall aviation industry accident rate. In this paper, we describe a cockpit-deployable machine learning system to support flight crew go-around decision-making based on the prediction of a hard landing event. This work presents a hybrid approach for hard landing prediction that uses features modelling temporal dependencies of aircraft variables as inputs to a neural network. Based on a large dataset of 58177 commercial flights, the results show that our approach has 85% of average sensitivity with 74% of average specificity at the go-around point. It follows that our approach is a cockpit-deployable recommendation system that outperforms existing approaches.
Flight Opportunities from Mars to Earth for Piloted Missions Using Continuous Thrust Propulsion

For a piloted Mars mission, the inbound flight (Mars to Earth) is actually the most restricting space-part of the mission – especially if short flight times and short stay times at Mars are required. In this paper, different electric propulsion systems (different thrust levels, specific impulses, and thrust to weight ratios) and different flight strategies for a crewed return from Mars are analyzed and compared to high thrust propulsion systems (chemical and nuclear thermal). This is done with respect to feasibility, flight times, propellant consumption, and influence on the roundtrip problem for launch opportunities within 2016-2031. It is demonstrated that with moderate continuous thrust levels and specific impulses (100N, 3000 s) – even for short stays at Mars – Earth return trips are feasible with moderate propellant needs and within reasonable inbound flight times of 200 to 350 days.
Quantitative Diffusion and Spectroscopic Neuroimaging Combined with a Novel Early-Developmental Assessment Improves Models for 1-Year Developmental Outcomes

BACKGROUND AND PURPOSE: Preterm infants are at risk for overt and silent CNS injury, with developmental consequences that are difficult to predict. The novel Specific Test of Early Infant Motor Performance, administered in preterm infants at term age, is indicative of later developmental gross motor and cognitive scores at 12 months. Here, we assessed whether functional performance on this early assessment correlates with CNS integrity via MR spectroscopy or diffusional kurtosis imaging and whether these quantitative neuroimaging methods improve predictions for future 12-month developmental scores. MATERIALS AND METHODS: MR spectroscopy and quantitative diffusion MR imaging data were acquired in preterm infants (n = 16) at term. Testing was performed at term and 3 months using the Specific Test of Early Infant Motor Performance and the Bayley Scales of Infant and Toddler Development, Third Edition, at 12 months. We modeled the relationship of MR spectroscopy and diffusion MR imaging data with both test scores via multiple linear regression. RESULTS: MR spectroscopy NAA ratios at a TE of 270 ms in the frontal WM and basal ganglia and kurtosis metrics in major WM tracts correlated strongly with total Specific Test of Early Infant Motor Performance scores. The addition of MR spectroscopy and diffusion separately improved the functional predictions of 12-month outcomes. CONCLUSIONS: Microstructural integrity of the major WM tracts and metabolism in the basal ganglia and frontal WM strongly correlate with early developmental performance, suggesting that the Specific Test of Early Infant Motor Performance reflects CNS integrity after preterm birth. This study demonstrates that combining quantitative neuroimaging and early functional movement improves the prediction of 12-month outcomes in premature infants.
Distance Sensitivity on Exported Products of the Swedish Manufacturing Sector

Distance increases transaction costs of rms engaging in export activities and the higher entry costs in turn aect the propensity to enter foreign markets. The type of products being exported, moreover, asserts dierent sensitivity towards distance due to relationship specicity required [24]. I estimate the product-level gravity equation by Heckman-type model on export propensity and volume of export, contrasting homogeneous and dierentiated products. The analyses uses Swedish export data within the manufacturing sector from 1997-2006 to 165 destination countries. The main ndings are in line with the hypothesis, suggesting that dierentiated products assert higher sensitivity towards distance. However, the results are not evident in non-aliated rms.
An Adaptive Hysteresis-Band Current Control Technique of a Voltage-Fed Pwm Inverter for Machine Drive System

An adaptive hysteresis-band control method where the band is modulated with the system parameters to maintain the modulation frequency to be nearly constant is described. Although the technique is applicable to general AC motor drives and other types of load, an interior permanent magnet (IPM) synchronous machine load is considered. Systematic analytical expressions of the hysteresis band are derived as functions of system parameters. An IPM machine drive system with a voltage-fed current-controlled PWM (pulse width modulation) inverter has been computer simulated to study the performance of the proposed method. >
Smart Graphics in Medical

Summary Smart graphics techniques have a great poten-tial in supporting medical treatment planning and education.In particular, the use of high-level knowledge and carefullyselected default values reduces the interaction effort in ex-ploring complex 3D data sets. Automatic viewpoint selectiontechniques may support the exploration of patient-speciﬁc3D models. Camera movements and other animation tech-niques allow to emphasize important anatomic structures andconvey complex spatial relations. Illustrative rendering tech-niques and smart visibility techniques enable the expressivevisualization of nested surfaces which is important, e.g., tounderstand the location of a tumor inside an organ. Gen-eral smart graphics techniques, however, have to be carefullyadapted to support medical applications. In-depth discussionsof usage scenarios, requirements, priorities and preferencesare therefore a prerequisite for successful developments. Inthis paper, we give an overview of smart medical visualiza-tions.
Fast approach for transient stability constrained optimal power flow based on dynamic reduction method

The main challenge to solve the transient stability constrained optimal power flow (TSC-OPF) problem is its huge dimension due to numerous discretised transient variables and constraints. This problem becomes more serious when large power systems are considered. This study presents a fast approach to realise a global TSC-OPF based on dynamic reduction method, which decomposes the power system into several coherent areas and represents the original system by a reduced equivalent system. In this approach, the single transient stability constraint is obtained by simulating the reduced system instead of the full system. The new approach reduces the simulation execution time and thus increases the efficiency of the TSC-OPF. Two case studies indicate that the proposed approach can remarkably reduce the CPU time of the TSC-OPF procedure, compared with the TSC-OPF based on the full-system simulation. The new approach is very practical in solving the TSC-OPF problem in large power systems where numerous machines are coherent.
Glossary to ARCH (GARCH)

The literature on modeling and forecasting time-varying volatility is ripe with acronyms and abbreviations used to describe the many different parametric models that have been put forth since the original linear ARCH model introduced in the seminal Nobel Prize winning paper by Engle (1982). The present paper provides an easy-to-use encyclopedic reference guide to this long list of ARCH acronyms. In addition to the acronyms associated with specific parametric models, I have also included descriptions of various abbreviations associated with more general statistical procedures and ideas that figure especially prominently in the ARCH literature.
Analysis and characterization of device variations in an LSI chip using an integrated device matrix array

For future LSI design technology, the device matrix array (DMA), which can precisely evaluate variation in device parameters within a die, has been developed. The DMA consists of a 14-by-14 array of common units. The unit size is 240 by 240 /spl mu/m, and each unit contains 148 measurement elements (52 transistors, 30 capacitors, 51 resistors, and 15 ring oscillators).
Could ground reaction forces be used to evaluate the stability of the shoe during locomotion?

The aim of this study is to determine if ground reaction forces (GRF) could be a significant parameter to evaluate the stability of the shoe. According to Forner Cordero (2003), the stability of an object is its capacity to maintain a balance and to resume its position (or sway) after a disturbance. So the stability of the shoe can signify its capacity to limit involuntary imbalances of the foot and of the ankle. Here, kinetics data (Fx, Fy and Fz for each foot) have been extracted during locomotion in different conditions (shod and barefoot conditions). Currently, stability is evaluated with 2D or 3D film analysis, or with the study of center of pressure path. This paper determines if another biomechanical parameter could be used to quantify the stability.
Fuzzy Inference System for Physical Activity Recognition Based on General Features and PCA

This paper presents an approach of applying principal component analysis (PCA) and fuzzy inference system (FIS) to recognition of activity of daily life (ADL). To overcome the non-intuitiveness of single acceleration signal and difficulties of feature selection manually, 32 common features are computed and PCA is used for feature reduction. The membership functions are obtained from training data, and fuzzy rules are in same form for all classes. Thus, the FIS is not dependent on expert knowledge of physical activity. Thus, this system is extendable on new types of activity, new features or new locations. This system is designed for a real-time sensor- based monitoring system to recognize 6 types of daily physical activities. Sitting, standing, walking, going upstairs, going downstairs and running are classified with a precision of 99.78%, 90.78%, 91.89%, 89.72%, 91.28% and 100% for each type.
Effect of level of substitution of sweet potato (Ipomoea Batatas. L) vines for concentrate on body weight gain and carcass characteristics of browsing Arsi-Bale goats

The study was conducted for 132 days on forty growing Arsi-Bale male goats of 16.78±0.61kg initial body weight to evaluate the use of fresh sweet potato vines (SPV) and concentrate given as sole or mixtures and also to determine the optimum level of substitution. Browsing goats were supplemented with SPV and concentrate, which was gradually replaced with fresh sweet potato vines at five levels: 0% SPV (T1), 25% SPV (T2), 50% SPV (T3), 75% SPV (T4) and 100% SPV (T5). There were no significant differences between T1, T2 and T3 in average daily gain (ADG). T1, T2 and T3 had significantly (P<0.05) higher ADG (g) (60.13 ± 0.004, 59.52 ± 0.002 and 56.34 ± 0.003 vs. 33.01 ± 0.003 and 20.83 ± 0.001) than T4 and T5, respectively. T5 had significantly (P<0.05) lower ADG (20.83 ± 0.001 g) than other treatments. There were no significant differences among treatments in carcass traits except in fat thickness (mm) which was highest (P<0.05) for T1 (1.67 ± 0.33) followed by T3 (1.33 ± 0.33), T2 (1.17 ± 0.44), T4 (1.17 ± 0.17) and lowest for T5 (1.23 ± 0.15). In general, there was no significant difference among treatments in primal cut (kg) except for T5 which had lowest (P<0.05) leg, loin and shoulder and neck than T1. Similarly, there were no significant differences among T1, T2 and T3 in muscle, fat and bone tissue. Therefore, from this study it can be concluded that 25 and 50% sweet potato vines substitution for concentrate can be used for growing Arsi-Bale male goats finishing with acceptable weight gain, carcass traits and compositions.
The complete chloroplast genome sequence of Gynura cusimbua (D. Don) S. Moore

Abstract Gynura cusimbua (D. Don) S. Moore is a favorite food vegetable and traditional folk medicine. The chloroplast genome information, of G. cusimbua, was introduced and released in this study. The complete chloroplast genome was characterized as 156, 684 base pairs (bp) in length. The circle gDNA contained four segments, namely LSC (large single copy), SSC (small single copy) and two IRs (inverted repeats), which was 86, 834 bp and 18, 414 bp and 25, 718 bp in length separately. The total GC content was 36.88%. A total of 125 genes were characterized in the chloroplast genome, where 84, 33 and 8 genes were for coding-proteins, tRNA and rRNA respectively. The phylogeny tree demonstrated that G. cusimbua was clustered with Jacobaea valgaris and Senecio valgaris. This study would fill a vacancy of chloroplast genome information involving G. cusimbua, and provide new genetic resources for the study on Senecioninae.
A multiwinding modeling method for high frequency transformers and inductors

This paper presents a method to obtain an electric model for transformers and inductors, including both frequency and geometry effects in the windings, which can be linked with existing core models. One-dimensional distributions for magnetic and electric fields are assumed, and from Maxwell's equations an equivalent electric circuit is easily obtained. This equivalent circuit has been included in analog simulators (Spice, AnalogWorkBench, Saber .), and comparisons between measured and simulated results are shown, both in time domain and in AC sweep, which verify the model accuracy. The model described in this paper allows designers to deal with key issues in the design of high-frequency magnetic components (copper losses, leakage inductance, skin and proximity effects) by using analog simulators, which are usually more familiar to them than finite-element analysis tools.
4 Tailoring Generic Systems Engineering Processes: an agent‐oriented method

The task of tailoring generic systems engineering process models to the particular needs of an organisation is addressed. Current process standards distinguish between different agents involved in a development process, for example, customer, developer and supplier roles. This approach is linked to existing agent‐oriented process modelling techniques, leading to an agent‐oriented method for tailoring systems engineering processes. Four process representations are developed to support the outline method. Objectives of the work include the embedding of systems engineering activity within the total end‐to‐end product development process, the organisation of legacy procedural documentation and support for defining information, tool integration and related needs.
Forest governance and development effects on tropical charcoal production and deforestation

Severe loss and degradation of tropical forests affects ecosystem services and livelihoods. Charcoal, an important energy and income source for millions of people, causes 7% of tropical deforestation and forest degradation. Forest governance aims to manage forest-related issues. On the one hand, development allows for financial investments in forest governance, e.g., in monitoring and enforcement, with the aim to control deforestation. On the other hand, deforestation often continues with increased human wellbeing. Here, we aim to (a) globally examine the effects of forest governance on charcoal production and deforestation, and (b) understand its association with development. We developed a typology of tropical forest governance systems based on a literature review of 54 USAID Country Profiles and combine it with global data on charcoal production, deforestation, governance quality and development. Our results suggest that countries’ development statuses affect charcoal production rather than governance quality; we observe a negative relationship between development status and charcoal production per capita (HDI: F (1,50) =4.85, p = 0.032; GNI: F (1,50) = 4.64, p = 0.036). The limited influence of governance quality and rights on charcoal production per capita and deforestation suggests mismatches between formal and informal governance and exposes challenges in top-down percolation of governance goals. Our results highlight the potential importance of tenure rights and potential opportunities for regional governing bodies to bridge local formal and informal actors to improve forest governance. Positive effects of regional tenure are driven by mixed effects of high development and governance quality related to decentralization in Asia and South America, highlighting transitions from charcoal as a livelihood energy source to a global commodity. Variability in results for FAO and UN charcoal production data advocates for better monitoring programs. However, for the first time, we explore global interactive patterns in charcoal production, development and governance—a starting point to differentiate good governance.
