Shape-Wilf-Ordering on Permutations of Length 3
Authors: Stankova Zvezdelina
Published: January 2020

The research on pattern-avoidance has yielded so far limited knowledge on Wilf-ordering of permutations. The Stanley-Wilf limits $\lim_{n\rightarrow \infty} \sqrt[n]{|S_n(\tau)|}$ and further works suggest asymptotic ordering of layered versus monotone patterns. Yet, Bóna has provided essentially the only known up to now result of its type on complete ordering of $S_k$ for $k=4$: $|S_n(1342)| < |S_n(1234)| < |S_n(1324)|$ for $n\geq 7$, along with some other sporadic examples in Wilf-ordering. We give a different proof of this result by ordering $S_3$ up to the stronger shape-Wilf-order: $|S_Y(213)|\leq |S_Y(123)|\leq |S_Y(312)|$ for any Young diagram $Y$, derive as a consequence that $|S_Y(k+2,k+1,k+3,\tau)|\leq |S_Y(k+1,k+2,k+3,\tau)|\leq |S_Y(k+3,k+1,k+2,\tau)|$ for any $\tau\in S_k$, and find out when equalities are obtained. (In particular, for specific $Y$'s we find out that $|S_Y(123)|=|S_Y(312)|$ coincide with every other Fibonacci term.) This strengthens and generalizes Bóna's result to arbitrary length permutations. While all length-3 permutations have been shown in numerous ways to be Wilf-equivalent, the current paper distinguishes between and orders these permutations by employing all Young diagrams. This opens up the question of whether shape-Wilf-ordering of permutations, or some generalization of it, is not the "true" way of approaching pattern-avoidance ordering.

Individual reading techniques (reading individually in front of ustadz / ustadzah).

2 The implementation equation between Iqra 'and Tilawati methods are: the use

of CBSA system (Active Learning Student), the use of Direct Spelling technique in

its reading, the use of Individual technique (individual reading in front of ustadz /

ustadzah), and compiled / Variative. As for the difference in the implementation of

Iqra 'and Tilawati methods are: for the Tilawati method using the National

Standard Rost song, while for Iqra' method it is not allowed to use the song even

though Irott Murottal; in Iqra 'method using sound approach for difficult letters in

its pronunciation, whereas in Tilawati method it is emphasized to pronounce

letters according to the right makhraj; besides using Individual reading technique

on Tilawati method also using classical technique, whereas in Iqra 'method only

use Individual technique only. 3 Factors that support the implementation of Iqra

'and Tilawati methods in Madrasah Diniyah Al-Falah Modung Bangkalan,

namely: the availability of props and tapes Murottal (with some type of rhythm of

the song); to shorten the time, as long as Individual ustadz / ustadzah assisted by

Authors: Manzano Cristina V , Schwiedrzik Jakob J , Bürki Gerhard , Pethö Laszlo , Michler Johann , Philippe Laetitia
Published: January 2020

Structural colours have produced immense attention in reproducing the vivid colours found in nature. In this study, metal-anodic aluminium oxide (AAO)-Al nanostructures were deposited using a two-step anodization and sputtering process to produce self-ordered anodic aluminium oxide films and a metal layer (8 nm Cr and 25,17.5 and 10 nm of Au), respectively. AAO films, of various thicknesses, were anodized and the Yxy values (Y, luminance, and xy, chromaticity) were obtained via reflectance measurements. An empirical model, based on the thickness and porosity of the nanostructures, was determined, which would describe a gamut of colours. The proposed mathematical model can be applied in different fields, such as wavelength absorbers, RGB (red, green, blue) display devices, as well as chemical or optical sensors.
Solving Galbrun's Equation with a Discontinuous galerkin Finite Element Method
Authors: Maeder Marcus , Peplow Andrew , Meindl Maximilian , Marburg Steffen
Published: January 2020

Over many years, scientists and engineers have developed a broad variety of mathematical formulations to investigate the propagation and interactions with flow of flow-induced noise in early-stage of product design and development. Beside established theories such as the linearized
Euler equations (LEE), the linearized Navier–Stokes equations (LNSE) and the acoustic perturbation equations (APE) which are described in an Eulerian framework, Galbrun utilized a mixed Lagrange–Eulerian framework to reduce the number of unknowns by representing perturbations by
means of particle displacement only. Despite the advantages of fewer degrees of freedom and the reduced effort to solve the system equations, a computational approach using standard continuous finite element methods (FEM) suff ers from instabilities called spurious modes that pollute the solution.
In this work, the authors employ a discontinuous Galerkin approach to overcome the difficulties related to spurious modes while solving Galbrun's equation in a mixed and pure displacement based formulation. The results achieved with the proposed approach are compared with results from previous
attempts to solve Galbrun's equation. The numerical determination of acoustic modes and the identification of vortical modes is discussed. Furthermore, case studies for a lined-duct and an annulus supporting a rotating shear-flow are investigated.

Role of Plate Length on Noise from Wall Jets
Authors: Arackal Rahul S. , Jothi T. J. S.
Published: January 2020

The present study experimentally investigates the effect of the growth of inner layer on noise emission characteristics of wall jets. The plate length L considered for the current study vary in the range of L/h = 2.5 to 30, where h is the nozzle height. The jet
is issued from a nozzle having the exit dimensions of 20 cm in width and 2 cm in height h. The jet Reynolds number, based on the nozzle height and jet exit velocity Uj, is varied up to 7.0 · 104. Acoustic measurements revealed the distinct variations in
the noise levels with different plate lengths. The L/h = 2.5 wall jet has an increase in noise levels by around 10 dB compared to that of a free jet (background noise). Wall jets in the range of L/h = 5 to 20 radiate higher noise levels compared to other plates, while the least
noise emissions are observed from fully developed wall jets (L/h > 20). The significant sources identified for noise emissions are the trailing edge and the secondary shear layer in the wall jets. The low frequency noise corresponding to the Strouhal number (based on h) below
0.2 is characterized as the trailing edge noise. The spectra of the wall jets collapse in the Strouhal number range (based on the inner layer thickness of wall jets) of ∼0.2 to 1.0 indicating the secondary shear layer noise of wall jets.

This paper describes a non-invasive ultrasound method to analyze and develop the usefulness of ultrasound testing of both raw and cooked samples of pork loins (with different cooking conditions), and in different measurement conditions (frozen and thawed). Besides studying ultrasound
pulse velocity (UPV), other ultrasound parameters were included such as FFT (Fast Fourier Transform) and attenuation, neither of which being commonly studied in this kind of work. The experimental study was carried out on pork loin pieces with 3 cm thickness, using a pair of transducers in
through-transmission mode (frequency range up to 100 kHz), and another one in pulseecho mode (frequency range up to 1000 kHz). The ultrasound parameters studied showed good discrimination between samples in the different conditions of measurement and cooking. These results consolidate ultrasound
testing as a non-destructive method well suited to this kind of meat product, both raw and cooked.
Performance of a Low-Height Acoustic Screen for Urban Roads: Field Measurement and Numerical Study
Authors: Forssén Jens , Mauriz Laura Estévez , Torehammar Clas , Jean Philippe , Axelsson Östen
Published: January 2020

Field measurements and numerical modelling were used to study the acoustic performance of a low screen in an urban road setting. The results show the usefulness of low screens as well as suggests improvements in screen design. For the measurements, an acoustic screen built up from concrete
modules was temporarily installed beside a small park on the reservation between a two-lane road and a track for walking and cycling. A larger traffic system, of which the two-lane road is a part, determines the daytime equivalent noise level within the urban area. The screen height was about
1.4 m as measured from the level of the road surface and the width of the screen top was 0.3 m. Measurements were carried out both at 20 m distance from the road (within the park) and at 5 m distance from the road (at the cycle track). Insertion loss in maximum level, using controlled lightvehicle
pass-by at 50 km/h, was measured to 10 dB at 5 m distance and to 6 dB at 20 m distance, at 1.5 m height. Insertion loss in equivalent level was measured within the park to 4 dB at 1.5 m height. A listening experiment confirmed a perceived improvement from installing the screen. The measured
results were also compared with predicted results using a boundary element method (BEM) and a noise mapping software, the latter showing good agreement, overestimating the equivalent level insertion loss by 1 dB in the park. The BEM comparison showed reasonable agreement in maximum level insertion
loss considering that facade reflections were excluded, with an overestimation of 5 dB at the cycle track, and good agreement in the park, overestimating by up to 1 dB the equivalent and maximum level insertion losses. BEM predictions were used to also investigate other screen designs, showing
a positive effect of an acoustically soft screen top, significant for a screen width of 0.2 m and increasing for wider screens.
Estimation of the Perceived Time of Presence of Sources in Urban Acoustic Environments Using Deep Learning Techniques
Authors: Gontier Félix , Lavandier Catherine , Aumond Pierre , Lagrange Mathieu , Petiot Jean-François
Published: January 2020

The impact of urban sound on human beings has often been studied from a negative point of view (noise pollution). In the two last decades, the interest of studying its positive impact has been revealed with the soundscape approach (resourcing spaces). The literature shows that the recognition
of sources plays a great role in the way humans are affected by sound environments. There is thus a need for characterizing urban acoustic environments not only with sound pressure measurements but also with source-specific attributes such as their perceived time of presence, dominance or
volume. This paper demonstrates, on a controlled dataset, that machine learning techniques based on state of the art neural architectures can predict the perceived time of presence of several sound sources at a sufficient accuracy. To validate this assertion, a corpus of simulated sound
scenes is first designed. Perceptual attributes corresponding to those stimuli are gathered through a listening experiment. From the contributions of the individual sound sources available for the simulated corpus, a physical indicator approximating the perceived time of presence of sources
is computed and used to train and evaluate a multi-label source detection model. This model predicts the presence of simultaneously active sources from fast third octave spectra, allowing the estimation of perceptual attributes such as pleasantness in urban sound environments at a sufficient
degree of precision.
Laboratory Methods with Imaginary and Simulated Contexts to Assess Noise Annoyance: A Comparison in Terms of Annoyance Model Testing
Authors: Marquis-Favre Catherine
Published: January 2020

Noise annoyance models using only mean energy-based indices provide weak prediction. Actually various factors influence noise annoyance. different studies from the literature are carried out in laboratory conditions to understand some factors with the long-term aim of enhancing noise
annoyance models. Laboratory experiments of assessing noise annoyance are based on imaginary or simulated context. The method with imaginary context is often questioned as participants listen to noise sequences. The current study aims at comparing the two methods in terms of total annoyance
model testing. It revealed that annoyance models, respectively built within imaginary and simulated contexts, provided similar prediction when they were tested using in-field annoyance responses. Thus, the laboratory method with imaginary context seems to be as suitable as the method with
simulated context to assess annoyance in laboratory conditions.
Numerical Modelling of Boundary Layers and Far Field Acoustic Propagation in Thermoviscous Fluid
Authors: Joly Nicolas , Honzík Petr
Published: January 2020

To model linear acoustics in a thermoviscous fluid in open domain and time-harmonic regime, a Finite Element formulation in a bounded meshed domain is combined with the integral representation of the field for the propagative solution. The integrals are non-singular and involve the
only Finite Element node values for temperature variation and particle velocity variables. To overcome the non-uniqueness of solutions at fictitious resonant frequencies, a Burton-Miller combination of integral representation is used. This formulation is suitable to compute acoustic radiation,
scattering and diffraction by objects or mutual interaction between transducers. Two-dimensional computational experiments are presented in an infinite, open domain (exterior), showing that the model can be achieved in meshing only a thin domain surrounding the physical boundaries of a device.
Rippled Depth Thresholds: Estimates Obtained by Discrimination From Rippled and Nonrippled Reference Signals
Authors: Supin Alexander Ya. , Milekhina Olga N. , Nechaev Dmitry I.
Published: January 2020

The objective of the study was to better understand of contribution of excitation-pattern and temporal-processing mechanisms of frequency analysis to discrimination of complex-spectrum signals in various discrimination tasks. Using rippled-spectrum signals, the ripple depth thresholds
were measured as functions of ripple density under conditions of rippled or non-rippled reference signals. With rippled reference signals, the ripple depth thresholds were as low as 0.11 at low ripple densities (2–3 cycles/oct) and rose to 1.0 at a ripple density of 8.9 cycles/oct. For
non-rippled reference signals, ripple depth thresholds were nearly the same as for rippled reference signals at ripple densities of up to 7 cycles/oct; at ripple densities of 10 cycles/oct and higher, ripple depth thresholds rose slowly and reached 1.0 at a ripple density of 26 cycles/oct.
The results hypothetically suggest contributions of the excitation-pattern processing and temporal-processing mechanisms of frequency analysis to discrimination of rippled signals. The excitation-pattern mechanism featured low depth thresholds at low ripple densities but could not function
at ripple densities above 10 cycles/oct. The temporal-processing mechanism manifested at higher ripple densities and non-rippled reference stimuli.
Numerical Optimization of a Bicylindrical Resonator Impedance: Differences and Common Features Between a Saxophone Resonator and a Bicylindrical Resonator
Authors: Colinot Tom , Guillemain Philippe , Doc Jean-Baptiste , Vergez Christophe , Jousserand Michael
Published: January 2020

This paper explores the analogy between a saxophone resonator and a bicylindrical resonator, sometimes called transverse saxophone or cylindrical saxophone. The dimensions of a bicylindrical resonator are optimized numerically to approximate a saxophone impedance. The target is the
impedance measured on an usual saxophone. A classical gradient-based non-linear least-square fit function is used. Several cost functions corresponding to distances to the target impedance are assessed, according to their influence on the optimal geometry. Compromises appear between the frequency
regions depending on the cost function. It is shown that the chosen cost functions are differentiable and locally convex. The convexity region contains the initial geometrical dimensions obtained by crude approximation of the first resonance frequency of the target. One optimal geometry is
submitted to further analysis using descriptors of the impedance. Its deviations from the target saxophone are put into perspective with the discrepancies between the target saxophone and a saxophone from a different manufacture. Descriptors such as harmonicity or impedance peak ratio set
the bicylindrical resonator apart from saxophone resonators, despite a good agreement of the resonance frequencies. Therefore, a reed instrument with a bicylindrical resonator could be tuned to produce the same notes as a saxophone, but due to differences in the intrinsic characteristics of
the resonator, it should be considered not as a saxophone but as a distinct instrument.

Authors: Modarres-Gheisari S. M. M. , Mohammadpour M. , Gavagsaz-Ghoachani R. , Safarpour P. , Zandi M.
Published: January 2020

Nanoemulsion preparation and improvement play a pivotal role in the area of pharmaceuticals, food, mechanical, and chemical engineering. The ultrasonic technique is one of the most commonly used methods in preparing nanoemulsion, related to mechanical and electrical engineering. The
present study aimed to evaluate the effect of edge fillet radius in four different layouts of a cubic ultrasonic microcontainer at different frequencies through 36 simulations by using COMSOL Multiphysics software. To this aim, the simulations were performed in three edge fillet radius values
of zero, 2.5 and 5 mm, and at the excitation frequencies of 20, 200 and 300 kHz. In this regard, experimental tests were carried out in two modes of: a) regular ultrasonic bath (RUB) and b) filleted-edges ultrasonic bath (FEUB). Based on the simulation and experimental results, the removal
of sharp edges has a positive influence on propagating waves, leading to an increase in the acoustic energy density at different frequencies and the effect was more significant at lower frequencies and layouts with more PZTs.

layers constituting the shells on the scattering phenomenon. The object of this work, is to study the influence of the layers thicknesses on guided waves, the overall thickness of the shells is fixed. The plane of modal identification was chosen to analyze the scattering phenomenon. We investigate
the resonance trajectories of the guided waves, especially the curves change. The investigation and comparison made on resonance trajectories, show a shape change, a gradual deviation, or both, appear on the resonance trajectories of different guided waves, for the reduced cutoff frequencies
of guided waves a sliding to higher and lower value are noticed. The interaction between guided waves is also manifested in the scattering phenomenon. The findings for the bi-layered cylindrical shells are then compared with those obtained for the mono-layered stainless steel and copper cylindrical
shells. Then, this work is completed by an investigation on the reduced cut-off frequencies of the A1 wave, that have been extracted for different possible values of the intermediary radius. In this part, to understand the observed phenomena, other examples of bi-layered
cylindrical shells are introduced. The obtained results are analyzed and investigated.

The IEC 60318-4 ear simulator is used to measure the insertion loss (IL) of earplugs in the ear canal of an acoustical test fixture (ATF) and is designed to represent an average acoustic impedance (in a reference plane) of the human ear. The ear simulator is usually modeled using a
lumped parameter model (LPM) which has frequency limitations and inadequately accounts for the thermo-viscous effects in the simulator. The simulator numerical models that can better deal with the thermo-viscous phenomena often lack essential geometric details. Most related studies also suffer
from the lack of experimental validation of the models. Therefore, a transfer matrix (TM) model of the IEC 60318-4 simulator is proposed based on a direct assessment of its geometric dimensions. Such a model is of particular interest for designing artificial ear simulators. The variability
in the simulator impedance due to the geometric uncertainties is quantified using the Monte Carlo method. The TM model is validated using i) a finite element (FE) model of the simulator and ii) impedance measurements with a sound intensity probe. It is found to better describe the simulator
impedance above 3 kHz compared to the LPM. The TM model is then coupled to a FE model of an occluded ATF ear canal to simulate the IL of an earplug in the frequency range [100 Hz, 10 kHz]. In the model, the simulator is considered as a cylindrical cavity terminated by an equivalent tympanic
impedance which is determined from the TM model to simulate the sound pressure measured at the real microphone position (not at the reference plane) in the ATF ear canal. The simulated IL is validated against i) that obtained with a complete FE model of the corresponding system and ii) measurements
using an ATF. The TM model is shown to better agree with the simulator FE model than the LPM above 6 kHz regarding the earplug IL simulated using this method.

The robustness of speech classification and recognition systems can be improved by the adoption of language distinctive phonetic feature (DPF) elements that can increase the effective characterization of a speech signal. This paper presents the results of applying Hidden Markov Models
(HMMs) that perform Arabic phoneme recognition in conjunction with the inclusion and classification of their DPF element classes. The research focuses on classifying Modern Standard Arabic (MSA) phonemes within isolated words without a language context. HMM-based phoneme recognition is tested
using 8, 16, and 32 HMM Gaussian mixture models. The monophone configuration is designed with consideration of 2-gram language model to evaluate the inherent performance of the system. The overall correct rates for classifying DPF element classes for the three versions of HMM systems are 83.29%
88.96%, and 92.70% for 8, 16, and 32 HMM Gaussian mixture model systems, respectively.
Lumped Parameter Description of Thermoviscous Acoustics in Tubes with Equilateral Triangular Cross-Sections
Authors: Christensen René
Published: January 2020

An accurate acoustic model of a tube in the millimeter or sub-millimeter size should include the losses that occur due to viscosity and thermal conduction, collectively termed thermoviscous losses. These losses are prominent in a boundary layer near the tube walls. Under the assumption
that the boundary layer is thick compared to a characteristic geometry length, such as the radius for a circular cross-section, and fills out the entire cross-section, the tube can be described via a lumped parameter model. The lumped parameters have been known for several decades for a tube
with circular cross-section, but the equilateral triangular tube has only been investigated in terms of transmission line parameters. The lumped parameters have here been established for the equilateral triangular tube as a truncated series solution of the transmission line parameters. One
result observed is that the lumped parameter model for a triangular tube has 38% more viscous loss than a circular tube for a given area.

This paper presents how the bifurcation diagram of a saxophone model is affected by the contact force limiting the displacement of the reed when it strikes the mouthpiece lay. The reed impact is modeled by a nonlinear stiffness and damping activated by contact with the lay. The impact
model is compared with the "ghost reed" simplification, where the reed moves through the lay unimpeded. Bifurcation diagrams in both cases are compared, in terms of amplitude of the oscillations and location of the bifurcations, on the solution branches corresponding to the first and second
register. The ghost reed simplification has limited influence at low values of the blowing pressure parameter: the diagrams are similar. This is true even for "beating reed" regimes, in which the reed coincides with the lay. The most noticeable discrepancies occur near the extinction of the
oscillations, at high blowing pressure.

It has been long theorized, but not directly observed, that low-frequency magnetosonic plasma waves can steepen and form shocks. We show an example of small-amplitude, sinusoidal magnetosonic waves at the proton gyrofrequency upstream of the Martian bow shock. We hypothesize that these waves are produced by an ion beam instability associated with the ionization of hydrogen atoms by charge exchange with solar wind protons, solar photoionization, and/or electron impact ionization. As the waves are convected toward the planet by solar wind flow, the wave amplitude grows due to additional free energy put into the system by further ion beam particles. Finally, the steepened waves form shocks. Because of their development, the shocks are periodic with the separation at the proton gyroperiod. These observations lead to the conclusion that newborn ions may play a crucial role in the formation process of some collisionless plasma shocks in astrophysical and space plasmas.
Is π Men c’s Atmosphere Hydrogen-dominated? Insights from a Non-detection of H i Lyα Absorption

Constraining the composition of super-Earth-to-sub-Neptune-sized planets is a priority in order to understand the processes of planetary formation and evolution. π Men c represents a unique target for the atmospheric and compositional characterization of such planets because it is strongly irradiated and its bulk density is consistent with abundant H2O. We searched for hydrogen from photodissociating H2/H2O in π Men c's upper atmosphere through H i Lyα transmission spectroscopy with the Hubble Space Telescope’s Space Telescope Imaging Spectrograph, but did not detect it. We set 1σ (3σ) upper limits for the effective planet-to-star size ratio R
Lyα
/R
⋆ = 0.13 (0.24) and 0.12 (0.20) at velocities [−215, −91] km s−1 and [+57, +180] km s−1, respectively. We reconstructed the stellar spectrum, and estimate that π Men c receives about 1350 erg cm−2 s−1 of 5–912 Å energy, enough to cause rapid atmospheric escape. An interesting scenario to explain the non-detection is that π Men c's atmosphere is dominated by H2O or other heavy molecules rather than H2/He. According to our models, abundant oxygen results in less extended atmospheres, which transition from neutral to ionized hydrogen closer to the planet. We compare our non-detection to other detection attempts, and tentatively identify two behaviors: planets with densities ≲2 g cm−3 (and likely hydrogen-dominated atmospheres) result in H i Lyα absorption, whereas planets with densities ≳3 g cm−3 (and plausibly non-hydrogen-dominated atmospheres) do not result in measurable absorption. Investigating a sample of strongly irradiated sub-Neptunes may provide some statistical confirmation if it is shown that they do not generally develop extended atmospheres.

Elderly patients with fungal pneumonia experience higher mortality and are more likely to be misdiagnosed. The diagnosis and treatment of fungal pneumonia in elderly patients is challenging. We herein present a clinical case of pulmonary fungal infection (PFI) manifesting as cavitary lesions in an 85-year-old male with multiple organ failure. Broad-spectrum antibiotics showed unsatisfactory result in this case. Computed tomography (CT) of the chest showed multiple pulmonary cavities with gas-fluid levels in the right upper and middle lobe, and patchy blurred shadows in the lower lobe. The diagnosis of fungal pneumonia was made after ruling out other causes of fever. The patient showed good response to anti-fungal treatment. Physicians must consider the possibility of fungal pneumonia in elderly patients who do not respond to antibiotic treatment after exclusion of immune response, tumor, tuberculosis, and other systemic infections.

Published: January 2020

Introduction: Farmworkers are considered a high-risk group for tick-borne diseases (TBDs). This qualitative study aimed to gain an in-depth understanding of the farmworkers’ experience, knowledge, health beliefs, information needs, and preventive practices of tick bites and TBDs.

Methodology: A total of nine focus group discussions with 56 farmworkers across eight animal farms in Peninsular Malaysia were conducted between August and October 2013.

Results: Farmworkers explained their experience of tick bites, but no one reported TBDs. Many farmworkers indicated that they did not seek any medical treatment. There was a misconception that ticks are solely pathogenic to farm animals. Farmworkers perceived low severity and susceptibility of tick bites, and low self-efficacy of tick bite prevention, however, a group also perceived susceptibility to getting tick bites due to the characteristics of their job. Barriers for prevention were related to the perception and knowledge towards ticks. Farmworkers requested information about TBDs.

Conclusions: This study of farmworkers identified gaps in the knowledge of TBDs, barriers of the tick bite preventive measures and information needs. These findings suggest a need for education programs to improve the knowledge of ticks and TBDs, change health beliefs and address the barriers of tick bite preventive measures.
