Graphic associative test of attitudes as a convenient implicit measurement tool for mass polls
Authors: Chernozub O. L.
Published: March 2023

Several latest elections and referendums were marked by the dramatic failure of electoral forecasts based on mass polls. To respond to the dissatisfaction of the public and politicians, alternative approaches like prediction markets, Implicit Attitude Test (IAT), expectationbased forecasts and so on were developed. IAT proves to be one of the most efficient ways to enrich the forecasting models and improve their accuracy. The problem is that the original form of IAT implies too rigid rules to be applied in the traditional mass poll. As a thorough laboratory-style measurement of nervous reactions to stimuli, IAT requires a special environment, for instance, nothing should disturb or distract respondents from performing experimental tasks. Such an environment is difficult to provide during the mass poll’s fieldwork; thereby, researchers usually implement IAT on small samples. This article presents the Graphic Associative Test of Attitude (GATA) as a tool for mass polls. It is the IAT’s functional analog developed by the author and tested in a wide range of preelectoral mass polls in Russia. GATA is easy to use even with inexperienced interviewers, and its simple and intuitive-clear tasks do not create additional barriers for respondents and do not decrease the response rate. At the same time, in a reliable way, GATA identifies implicit factors of behavior and helps to improve the accuracy of forecast. As a theoretical research, this study proves the ‘dual attitude’ concept of the structural theory of attitude.

Authors: Ryazantsev S. V. , Khramova M. N.
Published: March 2023

From August 22 to 26, 2022, the VIII International Congress of American Studies was held in Rio de Janeiro. This congress focused on the most pressing issues in the contemporary Latin American agenda - globalization and regionalization, economic development, impact of the covid-19 pandemic on social, political, economic, and demographic processes. As a part of the congress, the round table “Migration, Migrants, Migration Policy in the Era of the covid-19: Trends, Consequences, Conclusions” was held. Not only Latin-American researchers, but also scientists from the leading Russian, European, Asian universities and research institutes participated in the round table. They discussed transformations of the international migration and migration policy under the pandemic, ways to ensure the rights of migrants and refugees, state policy measures aimed at restoring internal and international mobility, interstate cooperation and the role of international institutions in ensuring safe, ordered and legal migration.
Investigation the Parameters of Non-Cylindrical Ice Load on Power Transmission Lines
Authors: AJDER Ali
Published: March 2023

Ice load on transmission lines is a critical factor that affects their cost and operation. National standards specify how ice load is considered in the design of power lines and poles. These standards generally use empirical relations that assume that the ice load on each phase accumulates uniformly and cylindrically. However, field tests and fault records show that the actual ice load on conductors is often not cylindrical due to altitude, wind strength and direction, and terrain topography. This study firstly defines several parameters to describe asymmetrical ice load. This load can cause additional vertical force on the line, conductor swing angle deviation, and sag changes. Since empirical equations are only valid for cylindrical ice load, the cross-sectional shape of the conductor must be transferred to millimeter paper, and calculations performed using one of several numerical integral methods. The coefficients for asymmetric ice are calculated in kg⁄m (N⁄m) using an AutoCAD model in the numerical study.
Modeling Multi-Scale Deformation Cycles in Subduction Zones with a Continuum Visco-Elastic-Brittle Framework
Authors: Dansereau Véronique , Shapiro Nikolai M. , Campillo Michel , Weiss Jérôme
Published: March 2023

The overwhelming amount of seismic, geodesic and in-situ observations
accumulated over the last 30 years clearly indicate that, from a
mechanical point of view, faults should be considered as both damageable
elastic solids in which highly localized features emerge as a result of
very short-term brittle processes and materials experiencing ductile
strains distributed in large volumes and over long time scales. The
interplay of both deformation mechanisms, brittle and ductile, give rise
to transient phenomena associating slow slip and tremors, known as slow
earthquakes, which dissipate a significant amount of stress in the fault
system. The physically-based numerical models developed to improve our
comprehension of the mechanical and dynamical behaviour of faults must
therefore have the capacity to treat simultaneously both deformation
mechanisms and to cover a wide range of time scales in a numerically
efficient manner. This capability is essential, both for simulating
accurately their deformation cycles and for improving our interpretation
of the available observations.In this paper, we present a numerically efficient visco-elasto-brittle
numerical framework that can simulate transient deformations akin to
that observed in the context of subduction zones, over the wide range of
time scales relevant for slow earthquakes. We implement the model in
idealized simple shear simulations and explore the sensitivity of its
behavior to the value of its main mechanical parameters.
Mapping the seismicity of Mars with InSight

Published: March 2023

InSight’s seismometers recorded more than 1300 events. Ninety-eight of
these, named the low-frequency family, show energy predominantly below 1
Hz down to ∼0.125 Hz. The Marsquake Service identified seismic phases
and computed distances for 42 of these marsquakes, 26 of which have
backazimuths. Hence, the locations of the majority of low-frequency
family events remain undetermined. Here, we use an envelope shape
similarity approach to determine event classes and distances, and
introduce an alternative method to estimate the backazimuth. In our
similarity approach, we use the highest quality marsquakes with
well-constrained distance estimates as templates, including the largest
event S1222a, and assign distances to marsquakes with relatively high
signal-to-noise ratio based on their similarities to the template
events. The resulting enhanced catalog allows us to re-evaluate the
seismicity of Mars. We find the Valles Marineris region to be more
active than initially perceived, where only a single marsquake (S0976a)
had previously been located. We relocated two marsquakes using new
backazimuth estimates, which had reported distances of ∼90o, in the SW
of the Tharsis region, possibly at Olympus Mons. In addition, two
marsquakes with little or no S-wave energy have been located in the NE
of the Elysium Bulge. Event epicenters in Cerberus Fossae follow a
North-South trend due to uncertainties in location, while the fault
system is in the NW-SE direction; therefore, these events are
re-projected along the observed fault system.
MLT dependence of relativistic electron scattering into the drift loss cone: Measurements from ELFIN-L on board Lomonosov spacecraft

Published: March 2023

There have been a number of theories proposed concerning the loss of
relativistic electrons from the radiation belts. However, direct
observations of loss were not possible on a number of previous missions
due to the large field of view of the instruments and often
high-altitude orbits of satellites that did not allow researchers to
isolate the precipitating electrons from the stably trapped. We use
measurements from the ELFIN-L suit of instruments flown on Lomonosov
spacecraft at LEO orbit, which allows us to distinguish stably trapped
from the drift loss cone electrons. The sun-synchronous orbit of
Lomonosov allows us to quantify scattering that occurred into the loss
cone on the dawn-side and the dusk-side magnetosphere. The loss at MeV
energies is observed predominantly on the dawn-side, consistent with the
loss induced by the chorus waves. The companion data publication
provides processed measurements.
On elements whose (b,c)-inverse is idempotent in a monoid
Authors: Zhu Haiyang , Chen Jianlong , Zhou Yukun
Published: March 2023

In this paper, we investigate the elements whose (b, c)-inverse is idempotent
in a monoid. Let S be a monoid and a, b, c ? S. Firstly, we give several
characterizations for the idempotency of a||(b,c) as follows: a||(b,c)
exists and is idempotent if and only if cab = cb, cS = cbS, Sb = Scb if and
only if both a||(b,c) and 1||(b,c) exist and a||(b,c) = 1||(b,c), which
establish the relationship between a||(b,c) and 1||(b,c). They imply that
a||(b,c) merely depends on b, c but is independent of a when a||(b,c) exists
and is idempotent. Particularly, when b = c, more characterizations which
ensure the idempotency of a||b by inner and outer inverses are given.
Finally, the relationship between a||b and a||bn for any n ? N+ is revealed.
Characterization of inner product spaces by unitary Carlsson type orthogonalities
Authors: Dehghani Mahdi
Published: March 2023

In this study, we consider the Hermite-Hadamard type of unitary Carlsson?s
orthogonality (UHH-C-orthogonality) to characterize real inner product
spaces. We give a necessary and sufficient condition weaker than the
homogeneity of symmetric HH-C-orthogonalities which characterizes inner
product spaces among normed linear spaces of dimension at least three. In
conclusion, some more characterizations of real inner product spaces are
provided.
Sparse recovery for compressive sensing via weighted Lp−q model

Published: March 2023

In this paper, we study weighted Lp?q minimization model which comprises
non-smooth, nonconvex and non-Lipschitz quasi-norm Lp(0 < p ? 1) and Lq(1 <
q ? 2) for recovering sparse signals. Based on the restricted isometry
property (RIP) condition, we obtain exact sparse signal recovery result. We
also obtain the theoretical bound for the weighted Lp?q minimization model
when measurements are depraved by the noises.

Authors: Mohamed Amin S. , Habumugisha Janvier , Cheng Bo , Zhao Minyue , Bu Wenqing , Liu Lifeng , Guo Yucheng , Zou Rui , Wang Fei
Published: March 2023

Objectives

To investigate hyoid bone position and airway volume in subjects with adenoid hypertrophy, tonsillar hypertrophy, and adenotonsillar hypertrophy compared to subjects with nonobstructive adenoids or tonsils and to assess the correlation between hyoid bone and airway parameters.

Materials and Methods

A total of 121 subjects were grouped based on adenoid or tonsillar hypertrophy into four groups, as follows: (1) control group (C-group), (2) adenoid hypertrophy group (AH-group), (3) adenotonsillar hypertrophy group (ATH-group), and (4) tonsillar hypertrophy group (TH-group). Hyoid bone position and airway volumes were measured. The Kruskal-Wallis test was used for intergroup comparison, followed by pairwise comparison using the Mann-Whitney U-test. Bivariate correlation was conducted using Spearman correlation coefficients. Multiple linear regression was performed to create a model for airway volume based on hyoid bone predictive variables.

Results

No significant difference was found between subjects with isolated adenoid or tonsillar hypertrophy compared to the C-group. However, the ATH-group exhibited a significantly decreased hyoid bone vertical distance (HV), total airway volume (TA volume), and retroglossal airway volume (RG volume) compared to the C-group. HV and age had a high potential in terms of explaining the RG volume, whereas the TA volume and retropalatal airway volume (RP volume) models were not as successful as the RG volume counterpart.

Conclusions

Subjects in ATH-group were characterized by an elevated hyoid bone position and constricted TA volume and RG volume compared to those in the C-group. HV and age were predictor variables that best explained retroglossal airway volume.

Published: March 2023

  

OBJECTIVE: To investigate the impact of factors in the first 1000 days of life on metabolic phenotypes of obesity in preschool children in a cohort study. 

RESEARCH DESIGN AND METHODS: 3-year-olds were recruited. Early life factors included maternal age at delivery, maternal education, prepregnancy BMI, gestational weight gain, gravidity, history of gestational diabetes mellitus, delivery mode, gestational age, family history of metabolic disorders, paternal education, annual family income, child sex, birthweight, and breastfeeding duration. According to BMI and metabolic status, children were classified as: metabolically healthy with normal weight (MHNW), metabolically unhealthy with normal weight (MUNW, normal weight and with ≥1 metabolic risk factor), metabolically healthy with overweight or obesity (MHO, overweight or obesity and without metabolic risk factors), and metabolically unhealthy with overweight or obesity (MUO). 

RESULTS: 3822 children were recruited, with 3015 analyzed. Accelerated BMI z score growth rate between 6~24 months was associated with MHO (β: 0.022; 95% CI: 0.009, 0.036) and MUO (β: 0.037; 95% CI: 0.018, 0.056). Maternal overweight (OR: 3.16; 95% CI: 1.55, 6.42) and obesity (OR: 8.14; 95% CI: 3.73, 17.76) before pregnancy and macrosomia (OR: 2.47; 95% CI: 1.32, 4.59) were associated with MHO, and maternal obesity before pregnancy (OR: 6.35; 95% CI: 2.17, 18.52) increased risk of MUO.

CONCLUSIONS: Early life factors such as maternal obesity and accelerated BMI growth rate between 6~24 months were not only related to MHO but also to MUO. Children with these early life factors should be given interventions for weight control to prevent metabolic abnormalities.

Air transport safety in UAV operational conditions
Authors: Bolz Katarzyna , Nowacki Gabriel
Published: March 2023

The article presents the possibilities of using unmanned aerial vehicles in air transport. The use of UAVs in the airspace has become widespread, despite many implemented legal regulations, there are many incidents that threaten not only aircraft during the flight, but also the airport infrastructure. The potential threats and the chances of implementing remedial measures were analyzed. An attempt to evaluate the possibility of maintaining aviation safety at an appropriate level in the conditions of UAV operational conditions has been done. The main research problem was defined as follows: How would implementing unmanned aerial vehicles into the air transport system influence the acceptable level of safety? The article uses theoretical methods such as: system analysis, analysis and synthesis in the field of literature, analogy, comparative method. In terms of empirical methods, an original diagnostic survey was carried out, based on a selected group of people related to the explored topic. In addition, the observation method was used by the feedbacks and observations of the group of air traffic controllers from civil airports (located in Poland). The article describes the current transformation of air transport, taking into account the planned modernizations. It presents the PansaUTM system as one of the countermeasures, monitoring and securing the movement in the airspace. Furthermore, the transponder issue was raised in relation to the enhancement of the UAV identification system, with a  detailed explanation of the importance of the TCAS (Traffic Collision Avoidance System). Referring to the prospects for the development of air transport, the latest design concepts for cargo drones were presented. The issue of full transport autonomy of UAVs was analyzed based on the requirements of legal regulations. The comparison of benefits and threats in conjunction with the conducted empirical methods allowed for the development of conclusions confirming the research hypothesis and indicating the possibility of using remedial measures in the process of UAV evolution.

“The World is still Beautiful”: An Eco-philosophical Reading of Eugene McCabe’s Victims Trilogy
Authors:   Universitat Internacional de Catalunya, Howes Christina Angela
Published: March 2023

This paper focuses on Irish writer, playwright and television screenwriter Eugene McCabe’s fictional representation of the Northern Irish ‘Troubles’ in his trilogy Victims, published in the collection Heaven Lies about Us (2005). Living most of his life on his family farm on the Monaghan/Fermanagh border between Northern Ireland and the Republic, McCabe had a deep understanding of the historically entrenched hatreds, bigotry and fundamentalisms of its inhabitants, and his fiction reflects the human tragedy underlying the violence. This paper draws on an eco-philosophical framework to suggest that by capturing the entanglement between the natural and cultural place-world McCabe’s poetics offers, from a liberal humanist perspective, an indictment of anthropocentric patriarchy at the root of violent dispute. McCabe’s literary world, evoking natural and cultural landscapes, encapsulates the absurdity of isolating territories via false political borders, marginalizing the value of bioregion and diversity and ignoring the vital oneness of humanity. Thus, though McCabe’s short stories are indeed culturally and politically specific, in shedding light on the self-destructiveness of human behaviour they are ultimately timeless and universal.

Erlendar rannsóknir sýna að mikill ávinningur geti verið fyrir nemendur að fara í starfsþjálfun á því sviði sem þau eru að mennta sig til. Nemendur öðlist meiri færni og séu líklegri en aðrir til þess að fá starf að námi loknu og því sé mikill ávinningur fyrir nemendur að ljúka starfsþjálfun (Di Stasio, 2017; Galloway o.fl., 2014; Maertz o.fl., 2014; Masevi?i?t? o.fl., 2018; Silva o.fl., 2018). Þá benda Mgaya og Mbekomize (2014) á að ávinningur fyrir stjórnendur og fyrirtæki felist í öflugri tengslum við háskóla, að starfsþjálfun hafi jákvæð áhrif á ímynd fyrirtækja og að þau uppfylli samfélagslega ábyrgð með því að taka inn nemendur í starfsþjálfun. Fáar rannsóknir liggja fyrir um ávinning og áskoranir starfsþjálfunar á Íslandi en Viðskiptafræðideild Háskóla Íslands hóf undirbúning að starfsþjálfun árið 2018 og hófst starfsþjálfun fyrir nemendur í grunnnámi og meistaranámi árið 2020. Frá þeim tíma hafa hátt í 100 nemendur lokið starfsþjálfun hjá yfir 40 félagasamtökum, fyrirtækjum, ráðuneytum og stofnunum. Markmið rannsóknarinnar var að skoða ávinning af starfsþjálfun og þær áskoranir sem nemendur og stjórnendur standa frammi fyrir meðan á starfsþjálfun stendur. Til þess að ná fram dýpri skilningi var eigindlegum rannsóknaraðferðum beitt og viðtöl tekin við 16 aðila, átta nemendur og átta stjórnendur, sem öll hafa reynslu af starfsþjálfun innan Viðskiptafræðideildar Háskóla Íslands.Niðurstöður viðtala leiddu í ljós að bæði nemendur og stjórnendur töldu mikinn ávinning af starfsþjálfun og töldu að hún veitti nemendum dýrmæta reynslu sem nýta megi í atvinnulífinu að námi loknu.

Published: March 2023

Feline coronavirus (FCoV) infections occur commonly in cats, with entrocyte and monocyte-macrophage tropism. Most FCoV-infected cats remain asymp tomatic, but up to 10% develop fatal feline infectious peritonitis (FIP). This study aims to investigate the diagnostic utility of clinical and laboratory examinations including serum and effusion AGP levels in cats either with symptomatic effusive FIP or asymptomatic feline enteric coronavirus (FECV). The study included 40 cats with effusive FIP and 10 cats with FECV infection. The FIP group was divided into two subgroups: abdominal (AE; n=30) and thoracic effusion (TE; n=10). Clinical and laboratory examinations, including serum or effusion AGP measurement, were performed. Among all the groups, TE group had higher body temperature, heart and respiratory rates (P<0.000). Compared with the FECV group, the FIP group had lower pH and HCO3 levels and higher base excess and lactate levels (P<0.05). The leukocyte and lymphocyte counts were higher and the hematocrit was lower in the AE group among all the groups (P<0.023). MCV was lower in the FIP group compared to the FECV group (P<0.002). In the AE group, total protein level was the lowest and the AST, GGT, total bilirubin and cholesterol levels were the highest (P<0.032) among all the groups. Magnesium level was lower in the FIP group compared to the FECV group (P<0.044). Although the serum AGP level was highest in the TE group among all groups (P<0.004), the AGP levels of cats with FECV were similar to the AE group (P>0.05). Since FECV-positive cats will likely develop FIP, differences in clinical and laboratory findings in FECV-positive cats were identified. Among them, pH, HCO3, base excess, lactate, MCV and magnesium were found to be important in the course of the disease, and AGP in the evaluation of the presence of an inflammatory state. It was concluded that clinical, laboratory and serum AGP evaluation could be used in the index of suspicion of development of FIP and FECV.
Study on Low-Velocity Impact Behavior of Twaron® Fabric Subjected to Double-Impactor Impact from a Numerical Analysis Perspective
Authors: Huang Canyi , Cui Lina , Qiu Yiping , Liu Yajun
Published: March 2023

In the present study, a finite element impact model was developed and analyzed using commercial FEM code ANSYS® and then validated via a drop-weight impact experiment. Moreover, double-impactor impact models were designed and developed with different impact distribution and locations of two impactors to compare impact properties. A total of 18 impact scenarios comprised of asymmetric and symmetric types were performed. The effect of impact location on the impact resistance force and duration time was investigated: the closer the impact point is to the fabric center, the longer the impact duration time. In addition, the effect of impact location on impactor failure deflection was also investigated and it was concluded that regardless of the symmetric or asymmetric impact scenario, the smaller the average distance between the impact location of the two impactors from the fixed boundary, the smaller the overall average failure deflection that occurs. The relevance of impact location and fabric energy absorption capacity was also identified. Furthermore, the effect of impact location on fabric stress distribution and transverse deformation and of the variation of the impact velocity on fabric impact behaviors were investigated. These findings will provide important guidance for engineering soft body armor and composite materials.
Fashion Consumption of Naturally Dyed Products: A Cross-Cultural Study of the Consumption of Blue-Dyed Apparel Between China and Japan
Authors: Xue Xing , Li Li
Published: March 2023

To compare the different motivation, intention and behaviour between Chinese and Japanese consumers in naturally dyed fashion consumption we collected 301 Chinese samples and 302 Japanese samples and used a structural equation model (SEM) to analyse the consumption behaviour of naturally dyed apparel based on the planned behaviour theory (TPB) and cross-cultural sustainable consumption framework (CCSC). The results indicate that attitude, social norms and perceived behaviour control (PBC) impact naturally dyed fashion consumption intention and behaviour. Among these relations, intention has a controlling influence on the relationship between subjective factors and actual consumption behaviour. PBC directly affects consumer behaviour. Moreover, the belief system and material source have a significant influence on all TPB constructs, wherein material source has more influence. Comparing China and Japan, attitude has a stronger impact on intention for Chinese than Japanese, but PBC influences Japanese intention more. Theoretically, this paper analyses the factors forming the difference in the strength of the TPB model from a cross-cultural perspective. The differences in Chinese and Japanese consumption behaviours also offer practical insights for the industrial development of natural dyeing.

Authors: Zou Yixin , Luh Ding-Bang , Pintong Sarawuth
Published: March 2023

The major of fashion performance is an emerging discipline, and the mode of talent training is still undergoing the process of exploration and improvement. The fashion performance major aims to cultivate talents with diversified abilities and a sense of social responsibility in the field of fashion or arts. In order to achieve this objective, the research proposes integrating the teaching mode and educational philosophy of the Capstone Course into fashion performance classes. The research employed case studies to analyze, compare, and summarize related cases, synthesizing the mode of the Capstone Course, which is highly integrated in terms of “knowledge, ability, and practice.” Through deduction, induction, and feasibility analysis, it is demonstrated that the application of the Capstone Course to teaching fashion performance is both practicable and advantageous. The research results offer suggestions regarding the teaching model for fashion performance majors. It may have theoretical guiding significance for the follow-up of the capstone course in the fashion performance major.
A Multivariate Regression Estimator of Levels and Change for Surveys Over Time
Authors: Konrad Anne , Berger Yves
Published: March 2023

Rotations are often used for panel surveys, where the observations remain in the sample for a predefined number of periods and then rotate out. The information of previous waves can be exploited to improve current estimates. We propose a multivariate regression estimator which captures all information available from both waves. By adding additional auxiliary variables describing the information of the rotational design, the proposed estimator captures the sample correlation between waves. It can be used for the estimation of levels and changes.

Objetiva compreender o significado da escolarização e o sentido do saber que jovens que realizam trabalhos precarizados atribuem à aprendizagem. Para tanto, analisa dados coletados em 2021, por meio de questionários e entrevistas em três escolas estaduais na cidade de São Paulo/Brasil. Os resultados indicam que a expectativa de ascensão econômica através de melhores empregos proporcionados pelo certificado de conclusão do ensino médio permanece, mas os/as estudantes também buscam empregos que satisfaçam as expectativas pessoais antes das financeiras. Conclui-se que o papel da escola de formar trabalhadores/as permanece, mas a relação com os saberes escolares vem se alterando. Foi possível identificar que as oportunidades no mercado de trabalho compõem um importante fator para a escolarização, entretanto a imagem do “bom trabalho” se relaciona a condição autônoma, pois tendem a ser mais satisfatórios para os/as jovens pelo controle que possuem do tempo.

Published: March 2023

The global population is projected to reach nearly 10 billion by 2050, increasing the need for food from a variety of sources, and the preservation and sustainability of food crops and feed is more important than ever before. However, today suffi cient food supply is limited to existing resources. Additionally, the food expected to be needed by 2050 is only discussed in the context of quantity needed, not the quality and types that such increased demand will require. This will put enormous pressure on global economic systems, especially given the economic shift in consumption patterns that are slowly but surely moving towards the mass market. It is a fact that global requirements for food quality and hygiene, as well as technological advances, have helped in the distribution of a larger amount of food - from basic food components to quality meat, fi sh and poultry, to the convenience of snacks and drinks. The growing shift towards healthy, functional and/or organic foods consumed by consumers in many countries, and the increasing demand for traditional and ethnic foods outside their region, may be the driving force for innovating new approaches to feeding the growing world population in the future. In this context, governments, research institutions and the global food industry, especially those focused on ethnic and traditional food gathering and food production, are likely to develop strategies that will target more people
Nonlinear Aeroelastic Prediction in Transonic Buffeting Flow by Deep Neural Network
Authors: Dou Zihao , Gao Chuanqiang , Zhang Weiwei , Tao Yang
Published: March 2023

Transonic buffet is an aerodynamic phenomenon of self-sustained shock oscillations. The aeroelastic problem caused by it is very complex, including two different dynamic modes: forced vibration and frequency lock-in. The vibration of the structure has a negative influence on the fatigue life of the aircraft. Especially in the region of frequency lock-in, the limit cycle oscillations occur due to the instability of the structural mode. Researchers have accurately predicted the region of frequency lock-in in transonic buffet and have clarified its mechanism by using a linear aerodynamic model. However, the nonlinear aeroelastic modeling and prediction of the transonic buffet remain to be solved. The long short-term memory (LSTM) deep neural network is suitable for predicting the time-delayed effects of unsteady aerodynamics. And it has achieved remarkable results in sequential data modeling. In the present work, a nonlinear model is developed for the aeroelastic system with NACA0012 airfoil in transonic buffeting flow and validated with the coupled computational fluid dynamics/computational structural dynamics (CFD/CSD) simulation. First, the data set and the loss function are specially designed. Then, the reduced-order model (ROM) based on the LSTM of the flow is built by using unsteady Reynolds-averaged Navier–Stokes computations data in a post-buffet state. By coupling the ROM and the single degree-of-freedom equation for the pitching angle, the nonlinear aeroelastic model is finally produced. The results show that the phenomenon of frequency lock-in and the self-sustained buffeting aerodynamics are precisely reconstructed. And the model has a strong generalization ability and can reproduce complex vibrations caused by competition between different modes. In short, the model can replace the CFD/CSD method in the current case with high efficiency and accuracy. The method can be used for modeling and prediction of other various complex aeroelastic systems.
Effects of Transverse Normal Stress on Hygrothermomechanical Analysis of Laminated Shallow Shells
Authors: Sayyad Atteshamuddin S. , Shinde Bharti M. , Kant Tarun
Published: March 2023

Hygrothermomechanical analysis of doubly curved laminated composite shallow shells is presented in this paper using a two-dimensional higher-order shell theory considering the effects of transverse normal stress. The present theory accounts for the fifth-order expansion of the thickness coordinates in the in-plane displacements and the fourth-order expansion in the transverse displacement. The main focus of this work is to study the effects of both transverse normal stress and the fifth-order expansion of thickness coordinates on the hygrothermomechanical responses of doubly curved laminated shallow shells. The governing equations of the theory are derived based on the principle of virtual work and solved by using Navier’s method. The theory ensures traction-free boundary conditions using constitutive relations and does not require a shear correction factor. Interlaminar transverse shear stresses are recovered using the three-dimensional equilibrium equations of the theory of elasticity to ascertain the stress continuity at the layer interface. Three-dimensional elasticity solutions are taken as a basis for comparing the present results in thermal problems, whereas this study contributes some useful results to the hygrothermomechanical analysis of doubly curved laminated composite shallow shells.
Experimental Investigation on Ice Accretion Upon Ice Particle Impacting onto Heated Surface
Authors: Hu Haiyang , Tian Linchuan , Hu Hui
Published: March 2023

An experimental study was conducted to examine the dynamic ice accretion process upon the impingement of microsized, airborne ice particles/crystals onto a heated test surface pertinent to aeroengine icing phenomena. The experimental study was conducted in a specially designed ice crystal icing test facility to generate and inject microsized ice particles into a frozen-cold airflow. The microsized ice particles were forced to impinge onto a heated test plate with controllable surface temperatures. Upon impingement of the ice particles onto the heated test surface, the dynamic ice accretion process was found to take place over the heated surface in three distinct stages: 1) an ice-melting stage at the beginning, followed by 2) an ice/water mixture formation stage, and then 3) a water refreezing stage, causing the formation of a solid ice layer accreted on the heated test surface eventually. After impinging onto the test plate, while small ice particles with spheric shapes were found to be more ready to bounce off from the test surface, large, nonspheric-shaped ice particles experienced a catastrophic fragmentation process and break up into smaller pieces with noticeable impingement residues remaining on the test surface. The formation of a liquid water film layer on the test surface due to the melting of the impinged ice particles was found to be very beneficial to make more impinged ice particles stay sticking on the test surface, resulting in a rapid growth of the water/ice layer accreted on the heated test surface. A comprehensive theoretical analysis was also performed to examine the unsteady heat transfer characteristics during the dynamic ice accretion process. The theoretic predictions of the collection efficiency of the impinged ice particles on the heated test surface and the temperature variations of the water layer at the initial ice-melting stage were found to agree well with the experimental measurement results.

In this paper, we study multi-cloud storage technologies that share information as a single system using services from different cloud providers. These technologies provide advantages related to the availability and cost but need protections from security threats such as collusion and data leakage, limiting its massive adoption. We analyze security methods for multi-cloud storage and present the last advances in the field. We show that security systems based on homomorphic encryption are more promising than conventional security methods due to the possibility of performing operations over encrypted data.

We demonstrate colloidal, layer-by-layer growth of metal oxide shells on InP quantum dots (QDs) at room temperature. We show with computational modeling that native InP QD surface oxides give rise to nonradiative pathways due to the presence of surface-localized dark states near the band edges. Replacing surface indium with zinc to form a ZnO shell results in reduced nonradiative decay and a density of states at the valence band edge that resembles defect-free, stoichiometric InP. We then developed a synthetic strategy using stoichiometric amounts of common atomic layer deposition precursors in alternating cycles to achieve layer-by-layer growth. Metal oxide-shelled InP QDs show bulk and local structural perturbations as determined by X-ray diffraction and extended X-ray absorption fine structure spectroscopy. Upon growing ZnSe shells of varying thickness on the oxide-shelled QDs, we observe increased photoluminescence quantum yields and narrowing of the emission linewidths that we attribute to decreased ion diffusion to the shell, as supported by P X-ray emission spectroscopy. These results present a versatile strategy to control QD interfaces for novel heterostructure design by leveraging surface oxides. This work also contributes to our understanding of the connections between structural complexity and PL properties in technologically relevant colloidal optoelectronic materials.
