Published: August 2023

O Transtorno do Espectro Autista (TEA) é caracterizado por dificuldades na interação social e na comunicação, além da presença de interesses e atividades restritas e repetitivas. É descrito como predominante no sexo masculino, entretanto, mulheres podem apresentar manifestações diferentes, o que pode contribuir para um subdiagnóstico. Mulheres com TEA, expressam comportamentos únicos para cada critério diagnóstico do transtorno, delimitando um fenótipo autista feminino, muitas vezes não reconhecido pelos instrumentos de investigação. Os atuais instrumentos utilizados para a avaliação do TEA são: Modified Checklist for Autism in Toddlers (M-CHAT-R/T), Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), Autism Spectrum Screening Questionnaire (ASSQ) e Autism Behavior Checklist (ABC). Esses instrumentos foram desenvolvidos com base nos fenótipos inicialmente descritos por Kanner e Asperger, que observaram uma amostra predominantemente masculina. A possibilidade de um viés de gênero nesses instrumentos diagnósticos pode levar ao subdiagnóstico e à sub-representação das mulheres no espectro autista.

The Historical Sociology of Class Formation in the Southern Kurdistan: 1921-1991
Authors: Kerimi Eyyub , Sabri Ali Dilshad
Published: July 2023

This article attempts to investigate the phenomenon of class formation in Southern Kurdistan from 1921 to 1991, during which the class structure of this society changed gradually. On this basis, a historical sociological reading of the political upheaval implications for class formation has been made in Southern Kurdistan. Since the establishment of the Iraqi state in 1921, under the supervision of a British Mandate, in Southern Kurdistan, which was regarded as a part of this country, the feudal system was dominant until the July 1958 revolution in Iraq and the coming to power of Abdulkarim Qasim, which began to reform agricultural lands. On the other hand, the successive uprisings of the Kurdish nation, especially the Eylul uprising in 1961-1975 had a significant influence on the formation and change of the class relations in Southern Kurdistan. As a result, in the late 1980s and early 1990s, there were significant changes in class relations, which led to the formation of petit-bourgeoisie that played a crucial role in the coming years in Southern Kurdistan.

Niger Delta Militants and Resource Control in Nigeria
Authors: Johnson Idowu , Lafenwa Stephen Akinyemi
Published: July 2023

For the past three decades, issues about the Niger Delta have attracted attention in scholarly discourse, policy cycle and global political economy as a result of the changing politics of oil exploitation and resource control in the region. There has been a wave of violent agitation by the communities in the region, with several militant groups demanding justice, equality, and socioeconomic development of their host communities. This paper examines the major cause of militant agitations in the Niger Delta region, especially from derivation principle for revenue allocation and resource control. The paper contends that militant agitations in the Niger Delta should be considered in the light of youth reactions to the prevailing decades of neglect of the region by the Nigerian state, rather than merely reducing it to youth restiveness and criminal act. The paper concludes that the issues raised by the militants over the Niger Delta crisis are very sensitive and bother on the very essence of fiscal federalism and must be resolved within the context of allinclusive national dialogue.
Pulse Picking PIV: A Single-Cavity Fiber Laser System For Highly Flexible Repetition Rates And Pulsing Schemes
Authors: Geschwindner C. , Westrup K. , Dreizler A. , Böhm B.
Published: July 2023

A novel single-cavity laser system with flexible pulsing schemes suitable for particle image velocimetry (PIV) measurements is presented. The system is based on the concept of picking selected pulse pairs from an ultra-high repetition rate fiber laser which enables time-resolved and conventional dual-pulse PIV at highly flexible recording frame rates. Pulse picking PIV laser systems allow for the use of high-quality low speed dual-frame PIV cameras as well as highspeed cameras in both dual-frame and continuous recording modes, enabling the investigation of highly-transient phenomena at limited fields of view using time-resolved PIV as well as statistical PIV measurements with larger fields of view and higher spatial resolutions. The single-cavity output additionally avoids the alignment of laser beams of laser pulses, which is otherwise necessary in conventional dual-cavity PIV laser systems. Two pulse picking systems were set up and tested: An acousto-optic deflector selecting pulses using the diffraction across an acoustic wave and an electro-optic modulator rotating the polarization state of selected pulses in a Pockels cell. The performance of both systems was evaluated in terms of achievable inter-pulse durations, beam profile alterations, and pulse energy losses caused by the introduction of additional optical elements in the beam path.
LEGO Calibration Targets For Large-FOV Particle Image Velocimetry
Authors: Parikh A. , Fuchs T. , Bross M. , Kähler C.J.
Published: July 2023

Particle-image or particle-tracking velocimetry (PIV/PTV) nonintrusively provides velocity field information, and consequently, the proposition of measurements in a large plane is highly attractive from an experimental standpoint, particularly for experiments conducted in large atmospheric and flight-scale wind tunnels. Physical limits to the size of the useful field-of-view (FOV) that can be achieved with a single camera depend on striking a balance between the physical capabilities of the cameras and the physics of interest in the flow. A typical solution is to stitch together multiple smaller FOVs to achieve the large FOV of interest, presenting a number of challenges, some of which are rooted in the calibration process. For SPIV calibrations, the use of a multi-level target simplifies the calibration process. However, this is problematic for large-FOV measurements, as standardised multi-level targets are typically relatively small and expensive due to the precision-engineering required. As an alternative, LEGO bricks are extremely well-suited to the construction of large, customised multi-level targets due to their high dimensional tolerance and their stackability with high precision. In order to create a prototype two-sided multi-level SPIV target and evaluate whether the LEGO bricks can be used successfully to calibrate a large FOV, the LaVision Type 31 target was chosen as a model. In order to further augment the flexibility offered by the LEGO-based targets, the backing used to mount the baseplates was designed to be modularly reconfigurable. The resultant two-sided multi-level target has an area of approximately 380 x 1150 mm. To evaluate the target, SPIV measurements of the inflow conditions of the Atmospheric Wind Tunnel Munich (AWM) were performed; calibrations were also performed using the Type 31 target for comparison. Analysis of the datasets with both calibration targets shows good agreement in the measurement of the streamwise, out-of-plane component u. However, there is some uncertainty regarding the accuracy of the computation of in-plane components. Due to the high level of agreement in calibration parameters, out-of-plane component, and the qualitative location of flow features, this disagreement is believed to be a fixable issue. These early results indicate that with some refinement, the LEGO-based calibration target can be developed further and used for large-FOV measurements in the future.
High-Speed Diagnostics For The Study Of Droplet Breakup
Authors: Dworzanczyk A.R. , Parziale N.J.
Published: July 2023

In this work, we demonstrate the use of planar laser-induced fluorescence (PLIF) and back-lit shadowgraph imaging at 1.75~MHz to study the breakup of a 1-mm-diameter liquid drop in the presence of an air jet intersecting the drop's velocity vector. For the PLIF, a 447-nm laser diode is focused to form a high-intensity sheet to excite the DCM dye suspended in the ethanol droplet. For the back-lit shadowgraphy, a 685-nm fiber-coupled laser diode is used to generate a collimated beam of light to illuminate a stream of droplets as they are disrupted by a jet of air. All the complications associated with performing experiments in a ballistic range (luminosity filter, single-event triggering, standoff distance, etc.) were taken into account in this laboratory setup.
Simultaneous Multiple Timescale Imaging For High-Speed Accelerometry Using The FRAME-Method
Authors: Kornienko V. , Andersson D. , Stiti M. , Ravelid J. , Ehn A. , Berrocal E. , Kristensson E.
Published: July 2023

Fast transient events, such as the disintegration of liquid bodies or chemical reactions between radical species, involve various processes that may occur at different timescales. Currently, there are two alternatives for monitoring such events: burst- or high-speed imaging. Burst imaging at ultra-high speeds (~ 100 MHz - THz) allows the fastest processes to be captured but only for a narrowly confined period of time and under the condition that the onset can be predicted. To monitor long lasting events with existing high-speed imaging technology, the frame rate must be reduced (~ kHz - 1 MHz) and thus processes occurring on sub-microsecond timescales cannot be observed. To date, no imaging technology is capable of visualizing detailed sub-microsecond dynamics over a long period of time. In this manuscript we present a solution to this technological gap by combining multiplexed imaging with high-speed sensor technology resulting in temporally resolved image series at two simultaneous timescales. We demonstrate its unique capability of tracking structures at MHz burst rates over a long time by, for the first time, extracting 2D accelerometry data acting upon liquid bodies at kHz frame-rates.
A Novel Multi-Step Multi-Exposure PTV Algorithm With Adaptive Time Separation
Authors: Saredi E. , Sciacchitano A. , Scarano F.
Published: July 2023

This work proposes a new multi-step measurement algorithm for PTV to cope with high flow velocities that do not allow time-resolved measurements. The proposed methodology relies on an iterative process, whereby a double-frame single-pulse image acquisition is followed by a multi-exposure acquisition. The novelty of the approach lies in the adaptive selection of the time separation used in the second acquisition to maximise the measurement dynamic velocity range and minimise the occurrence of overlapping particle images. The adaptive selection is performed based on the velocity field obtained by the first double-frame single-pulse acquisition and aims to obtain a rather uniform particle displacement across the measurement volume. The proposed methodology is demonstrated based on flow measurements in the near-wake of a truncated cylinder at Re=33,000. The results obtained by the presented method are then compared to those retrieved via the state-of-the-art PTV algorithm Shake-The-Box, a double-frame single-exposure strategy and a standard double-frame double-exposure strategy with a fixed pulse separation time. The increment of the particle displacement in the regions characterized by low velocity leads to a reduction of the relative uncertainty of the evaluated velocity and a consequent increase of the achievable dynamic velocity range. Among the double-frame strategies, the requirement to allow PTV measurement at a relatively high speed, the proposed methodology achieves the lowest error with respect to the reference, given by STB measurement in this case.
On the wake dynamics of a cylinder with flexible splitter plate
Authors: Saiz G.G. , Sciacchitano A. , Scarano F.
Published: July 2023

An experimental investigation is carried out to study the effect of a flexible splitter plate on the wake dynamics of a circular cylinder. Several regimes of foil motion are imaged and identified in the range of free stream velocities 1e4 < Re < 1e5. Based on the amplitude and the span-wise coherence of the plate motion, the regimes are classified into 4 categories: low oscillations, resonance, chaotic, and bi-stable. Wind-tunnel experiments are conducted on the resonant and chaotic regimes to further explore the cylinder-plate flow. Object surface and flow tracers are tracked by a volumetric Particle Image Velocimetry system based on four high speed cameras and LED illumination. The images are analysed with Lagrangian Particle Tracking techniques and the flow tracers and surface markers are separated based on the different properties of their images. A statistical analysis of the stream-wise and transverse velocity components on the cross-sectional plane compares the pure cylinder flow to the cylinder with the trailing splitter plate. Proper Orthogonal Decomposition is applied to study the most dominant modes from each flow. Results show two different coupling mechanisms pertaining to different aeroelastic regimes. In the resonant regime, the first bending mode of the flexible plate is excited by the shedding frequency. Overall, the results showed a one-way coupling between the flow and the plate, meaning that the motion of the structure was driven by the dominant features of the flow, whereas the flow was mostly unaffected by the presence of the flexible plate. The chaotic regime is an example of full interaction, i.e. 2-way coupling between flow and structure, where the addition of the plate disrupts the shedding structures of the cylinder wake flow. The three-dimensional motion of the flexible plate enhanced the span-wise flow oscillations and so, the three-dimensional features of the wake.
Progress Towards Full-Scale (In Situ) Flow Measurements

Published: July 2023

Recent advances in tracer, illumination, and camera technology, paired with new processing algorithms, have been pushing the limit of scale for three-dimensional flow measurements. The present study reflects on the state-of-the-art and discusses the required steps to enable full-scale, in situ flow measurements in very large measurement volumes. In particular, we focus on industrial and environmental applications, where the measurement time, the processing time, and the costs all have to be minimized. A single-camera approach that enables measurements with natural illumination in very large volumes is presented. The required infrastructure is discussed along with experiments to quantify the experimental errors of the proposed single-camera approach.
System Identification For Enhanced Flow Description From Multi-Pulse PIV
Authors: García-Caspueñas P. , Discetti S.
Published: July 2023

We propose a novel approach to obtain a time-resolved description from non-time-resolved PIV measurements. The method needs in input velocity and acceleration fields from ( at least) 3-pulse PIV data, without time r esolution. A sparse identification of nonlinear dynamics (based on the SINDy technique) is carried out to estimate the time history of coordinates in a low-dimensional space from Proper Orthogonal Decomposition (POD). The output is a reduced-order model of the dynamics which can be integrated to obtain time-resolved velocity fields using t he s napshots as i nitial c onditions. The t ime-resolved e volution of t he pressure fields is th en derived from the momentum equation. The time history of the velocity and pressure fields is obtained through a weighted Backward-Forward Integration (BFI) of the identified s ystem. Time super-sampling can be achieved by integration between consecutive non-time-resolved realizations. In alternative, simple one-directional time integration can be used for short-time prediction starting from individual snapshots. The algorithm is validated using a synthetic test case from 2D Direct Numerical Simulation of the wake of a fluidic pinball at a Reynolds number Re equal to 130, and PIV measurements of the wake of a NACA 0018 wing profile with Re = 4 800. We show that the method is able to reconstruct the flow dynamics for horizons of several convective times, provided that the basis for the data reduction is sufficiently c ompact. Our results suggest that manifold learning and data assimilation can be combined to obtain an enhanced flow description.
Phase Doppler Anemometer - The Shift From Simulation To The Real World
Authors: Meyers J.F. , Wigley G. , Jedelsky J. , Maly M. , Cejpek O.
Published: July 2023

A Monte Carlo type simulation program has been developed to model phase Doppler systems. The work was divided into four main sections, the development of a launch strategy of a known range of droplet sizes and trajectories, the determination of the scattered light fields using Mie theory, the generation of the photomultiplier signals, and then their processing to generate drop size estimates followed by the comparison of these data with the launched data. The signal processing portion of the simulation measured the Doppler frequency in each signal to estimate the droplet velocity. Rather than using measurements of the phase differences between the multiple Doppler-shifted signals, the time shift between the arrival times of each signal was used to estimate the dropsize. This provided a linear relationship between the dropsize and the signal time shift. The missing link in the simulation is the ability to guide the experimentalist as to the best way to acquire the signal bursts and determine how accurate the measurements would be when using a PDA system to determine the droplet size distributions in real spray flows. Thus, the only way to determine measurement accuracy is to include that in the signal processing of an actual PDA system and spray. In an assessment of the capabilities of the signal processing technique, a sequence of Doppler bursts from an actual spray characterization were recorded and used as input to the software signal processor. The Time Shift Technique was based on the use of Weighted Average calculations to determine the exact middle of each of the three photomultiplier signal bursts. However, it was found that good quality signal bursts are required. Since cycle measurement techniques are less effected by noise, a cycle technique based on the samples captured by the AD converter was added to the software. Whereas this technique did show an improvement in measurement accuracy it led to the development of a cycle technique based on the signal burst frequency. This involved a reconstruction of the original captured bursts. The measurement errors were found to be in the micron range.
Distortion Correction In Particle Image Velocimetry For Measurements Through Fluctuating Interfaces Using A Deep Neural Network And Wavefront Sensing

Published: July 2023

Imaging-based flow measurements like Particle Image or Particle Tracking Velocimetry re-quire an undistorted optical access to the measurement location. Changes of the refractive index in the light path can cause image deterioration and lead to severe measurement errors. While static aberration as e.g. from curved walls can be corrected by of means static correction optics or dedicated light ray models, this is hardly possible if the aberration change with time at high bandwidth. Many cases of this kind exists in fluid mechanics as e.g. free liquid jets, bubbles, droplets or film flows. These interfaces are related to several open research questions that concern the interaction between the media on both sides of the interface. Hardware-based corrections adapted from astronomy that employs a deformable membrane mirror, a wavefront sensor and a fast control electronics are a viable approach for solving this measurement problem. However, these closed-loop control schemes require extensive and dedicated hardware and are limited by the technical specifications of the adaptive optical mirror in terms of correction bandwidth, stroke and spatial resolution. Here we present an approach based on Multiple-Input deep convolutional neural network that works with a wavefront sensor only and spares the adaptive optical component. Based on a model experiment and a PIV measurement, we demonstrate that this system is able to correct for the errors that are induced by an oscillating water surface by 82 %. The technique can be an alternative to classical closed-loop adaptive optical systems where the performance of the actuators is not sufficient. This can open a perspective towards measurement of interface-related flows that were not accessible before.
Wavelet-Based Optical Flow For High-Resolution Velocimetry In Wall-Bounded Fluid Flows
Authors: Nicolas A. , Zentgraf F. , Linne M. , Dreizler A. , Peterson B.
Published: July 2023

The performance of a wavelet-based optical flow velocimetry (wOFV) algorithm in extracting high accuracy and high resolution velocity fields from tracer particle images in wall-bounded flows is as sessed. wOFV is first evaluated using a DNS database of a turbulent boundary layer, which served as ground truth synthetic data. The sensitivity of wOFV to the regularization parameter (λ) is quantified and results are compared to commercially available PIV crosscorrelation-based processing. Results on synthetic data indicate a slight preference towards under-regularization in the viscous sublayer region to minimise error. Nonetheless, tests on synthetic data reveal that wOFV can modestly outperform PIV in terms of accuracy for a broad λ range. For the synthetic dataset, wOFV revealed clear advantages over PIV in terms of vector resolution, being able to resolve 29 vectors in the viscous sublayer (versus 5 for PIV) and provide 13 vectors closer to the wall than PIV. wOFV was also applied to experimental data of a turbulent boundary layer near the leading edge of a side-wall quenching burner setup and compared to PIV. Good agreement between the two velocimetry techniques was found, with wOFV exhibiting superior vector resolution. Based on theoretical relations of the viscous sublayer, a physically justified λ weighting for wOFV was d etermined. With this setting, wOFV was able to resolve further and more accurately into the viscous sublayer. Analysis of the turbulent velocity fluctuations revealed some spurious results for PIV in close proximity to the wall, leading to significantly exaggerated turbulence intensity in the viscous sublayer region. wOFV did not exhibit this same effect, revealing that it is less biased by the presence of the wall and decreased image signal-to-noise ratio. These aspects show that wOFV can provide improved accuracy and reliability in resolving turbulent motion occurring in the vicinity of physical boundaries.
