Authors: Reutov Aleksandr
Published: May 2023

The study objective is to analyze the influence of elastic-damping characteristics of the two-mass flywheel of the internal combustion engine on the torsional vibrations of the car transmission components.

The task is to define the characteristics of forced stationary torsional vibrations of transmission parts under the action of torque fluctuations of the internal combustion engine.

Methods: mathematical and computer modeling of forced torsional vibrations of transmission parts.

The novelty of the work is in developing mathematical and computer models of the torsional vibrations of a car transmission with a two-mass flywheel and a double dry clutch, defining the conditions for preventing the resonance of the flywheel torsional vibrations at idling speed.

Results: mathematical and computer models are developed for the analysis of torsional vibrations of a car transmission with a two-mass flywheel and a double dry clutch. The analysis of forced stationary torsional vibrations of transmission parts in time is carried out. The conditions for preventing the resonance of the flywheel torsional vibrations at idling speed are defined.

Authors: Puzanov Andrey , Kurdubanov Sergey
Published: May 2023

The study objective is to improve the operational characteristics of hydraulic drives. The task to which the paper is devoted is to simulate operating processes and minimize the vibrations of the drive hydraulic and mechanical components based on the analysis of the main types of generators and dissipators of acoustic vibrations in hydraulic systems.

Research methods: analysis of complex multidisciplinary models of hydraulic machine operating processes. Macro-models provide solutions to problems at the system level. Micro-models provide an analysis of the operating processes of hydraulic drives, taking into account the influence of internal and external factors of impact operating, the interaction of components and parts, changes in structural and technological parameters.

The novelty of the work is in the substantiation of the influence of operational factors, structural and technological parameters on the vibration processes that form the acoustic characteristics of the hydraulic drive.

The results of the study are presented on the example of reducing the vibration processes of an axial plunger hydraulic machine. Fluctuations in the operating pressure are given in the indicator diagram. The vibration amplitude depends on the dead volume of the piston chamber, as well as due to its under-filling operation at low temperatures. Also, based on the simulation results, zones of energy dissipation of the working fluid are localized to reduce vibration processes. Conclusions: the obtained results of modeling various measures to reduce the vibration processes will allow to localize and reduce the negative factors of noise generation.

Published: May 2023

A study of various types of malfunctions in railway transport is conducted. Their critical impact on the safety of operation is evaluated. The research is aimed at studying statistical data on appearing failures and malfunctions both on rolling stock and on railway tracks. At high loads on mechanical components, the probability of various defects is high, which requires the most thorough study of the reliability of structural elements. Any deviation can lead to significant breakdowns and cause huge damage, especially for rolling stock for passenger transportation or transportation of dangerous goods. It is also necessary to predict the indicators of reliability and stability of the system to various impacts. In this regard, the study is aimed at evaluating the failures of railway systems and their critical impact on traffic safety. Despite such a great interest in the problems of evaluating and ensuring the safety of railway transport, there is still no unambiguous evaluation of the parameters of railway carriages and the track for the maximum stability coefficient, if exceeded, the train is highly likely to derail.
EVALUATION OF VIBRATION EFFECTS OF BULKY ELEMENTS ON THE CYLINDRICAL PART OF TANK CAR BOILERS BASED ON SHELL THEORY
Authors: Grigor'ev Pavel , Korzhin Sergey , Ibodulloev Sherzod , Goncharov Vladimir
Published: May 2023

The problems related to the vibration effects of bulky elements on the cylindrical shell of tank car boilers are considered. To do this, an approach based on the shell theory is proposed. Donnell equations are used to define the loading during vibrations.

Equations based on the theories of depressed cylindrical shells and on the polytechnic theory of shells are used. In order to confirm the reliability of the results obtained according to the proposed approach comparative analysis is performed. The rigidity of the attached cylindrical shell is estimated, for which experimental values of deformation under the local load are obtained.

The results of calculations for the local single load of a closed cylindrical shell by means of finite element method (FEM) are given. These results show a satisfactory conformity with the data obtained experimentally (based on calculations). Using the proposed technique, the authors evaluated rigidity of the boiler cylindrical part where bulky elements are installed and this makes it possible to define the values of natural frequencies and the level of dynamic addition for various design parameters. Geometrics for tetra axial and eight axial tank cars are used as examples. Additionally, gain-frequency characteristics of deformations, accelerations and dynamic coefficients in the places of bulky elements are presented. Study results can be used to improve the design and the conditions for using tank car boilers.

The (null) effect of situational loneliness on the sense of duty to vote and strength of electoral outcome preference - an experimental approach
Authors: Langenkamp Alexander
Published: May 2023

The importance of social ties for voter turnout has a long history in electoral research, and decades of research have established that social ties foster voter turnout. However, the hypothesis that perceived loneliness exerts an influence on voting behavior has just recently been put forward. This research paper adds to this line of research. Utilizing novel data from a pre-registered [Blinded for Review] survey experiment (n=573), this study investigates the relationship between situational loneliness and two major predictors of voter turnout: 1) sense of duty to vote 2) strength of electoral outcome preference. The experiment does not find a statistically significant relationship between induced loneliness and the two dependent variables. In light of cross-sectional findings that loneliness is linked to voting and sense of duty to vote, the experiment suggests that these associations are due to chronic rather than situational loneliness.

membayar zakat merupakan salah satu dari konsekwensi keimanan kepada Allah SWT. Realitas ditemukan, masih banyaknya di antara masyarakat yang memiliki kelebihan harta dan dapat dikategorikan sebagai muzakki, namun mereka masih merasa keberatan atau enggan dalam membayar zakat harta. Motivasi masyarakat dalam membayar zakat dipengaruhi oleh beberapa faktor yaitu faktor kebutuhan untuk mensucikan harta yang dimiliki yang mengandung suatu kemaslahatan berupa keberkahan, faktor dorongan dimana membayar zakat karena menjalankan perintah Allah SWT semata, harta yang dimiliki memenuhi nisab dan haul, dan kepedulian terhadap kondisi fakir miskin. Serta faktor tujuan dimana membayar zakat untuk mencari ridha Allah SWT dan mengharapkan balasan syurga, takut mendapat azab neraka, dan menghilangkan sifat kikir.Dengan adanya pendistribusian zakat yang merata dan tepat sasaran dapat meningkatkan tingkat kesejahteraan masyarkat. Kesejahteraan masyarakat ini mencangkup, yaitu memiliki cadangan makanan untuk kebutuhan, mampu membeli dan memiliki pakaian yang layak, memiliki rumah, memiliki tabungan pendidikan, memiliki tabungan kesehatan, dan merasa aman dalam menjalani kehidupan.

Exploring Joint Attention in American Sign Language: The Influence of Sign Familiarity
Authors: Sander Jennifer , Lieberman Amy , Rowland Caroline F
Published: May 2023

Children’s ability to share attention with another social partner (i.e., joint attention) has been found to support language development. Despite the large amount of research examining the effects of joint attention on language in hearing population, little is known about how deaf children learning sign languages achieve joint attention with their caregivers during natural social interaction and how caregivers provide and scaffold learning opportunities for their children. The present study investigates the properties and timing of joint attention surrounding familiar and novel naming events and their relationship to children’s vocabulary. Naturalistic play sessions of caretaker-child-dyads using American Sign Language were analyzed in regards to naming events of either familiar or novel object labeling events and the surrounding joint attention events. We observed that most naming events took place in the context of a successful joint attention event and that sign familiarity was related to the timing of naming events within the joint attention events. Our results suggest that caregivers are highly sensitive to their child’s visual attention in interactions and modulate joint attention differently in the context of naming events of familiar vs. novel object labels.

Multiversal Methods and Applications
Authors: Cantone Giulio Giacomo , Tomaselli Venera
Published: May 2023

Multiverse analysis is a paradigm for estimation of the uncertainty regarding the veracity of a scientific claim, through a systemic not random sampling of a massive set of specifications of a model, which is the multiverse. Specifications, once fit on a sample, result in statistics. Observation of the variability of result statistics across groups of specifications is considered useful for checking the robustness of the claim or for better understanding its premises. However, the assumptions behind theseprocedures are not explicit and not always univocal: generally, the proprieties of a multiversal sample hold uniformly only for non-parametric assumptions. A new formal categorisation of the analytical choices in modelling is proposed. It helps to make the assumption of the multiverse more transparent and to check the parametric assumption. These theories are applied to the panel dataset. The analytical process is documented from the design of the hypothesis to the computation of the distribution of estimates for the same generalised linear effect. The analysis highlights the sensitivity of the model to the estimation of fixed covariates in the panel and how these results are so sensitive to this decision to twist the estimates of the linear effect. In the conclusion, the theory of multiversal sampling is related to the debate on how to weigh a multiverse.
A Multiversal Model of Vibration of Effects of the Equitable and Sustainable Well-Being (BES) on Fertility
Authors: Cantone Giulio Giacomo , Tomaselli Venera
Published: May 2023

This study checks the hypothesis that sustainable well-being is a determinant factor of fertility through the application of a multiversal method based on the assumptions of Vibration of Effects (VoE) model of multiversal sampling on the Italian Equitable and Sustain-able Well-being (BES) dataset. For 48 social indicators of well-being, adopting the Province as statistical unit, the estimate of linear effect has been systematically sampled 1,024 times. This multiversal sampling allows to estimate the component of the hypothetical variability of the estimate of the effect size that depends on the theoretical choices of the analysis. This component is commonly underestimated, hidden, or ignored in regular multivariate analysis or classical bootstrapping. Results do not allow to claim that any of the 48 social indicators is a robust linear predictor of fertility. Indicators associated with high statistical significance are also at risk of misleading the causal relationship. Implications for policy-making and the future direction of the research on BES are discussed in the conclusive remarks.
Momentary profile similarity measures to capture similarity in multivariate dyadic time series

Interpersonal relationships impact our health and well-being, whereby interpersonal similarity in for example personality or experienced emotions is an important facilitator. Until now, this interpersonal similarity has mostly been examined using variable-centered (i.e., one variable at a time) and cross-sectional approaches. However, interpersonal similarity often concerns multiple variables simultaneously (e.g., multiple personality related behaviors or emotions) and can be expected to change over time and contexts. We therefore propose a workflow that combines existing methods to optimally capture dyadic similarity in a multivariate, timepoint-specific way, by computing and modeling momentary profile similarity values. We illustrate the different steps of this workflow by applying it to an existing longitudinal data on the multivariate emotional experience of romantic couples. We will show how to compute momentary profile similarity values with two different indices for these data and how to explore and model the differences in these values across time by relating them to time-invariant and time-varying predictors.

Theoretical accounts of narcissism emphasize dynamic shifting of self-states in response to social feedback. Status threats are thought to set narcissism’s dynamics in motion. Naturalistic ecological momentary assessment studies have characterized dynamics of narcissistic grandiosity and vulnerability in relation to perceptions of the interpersonal environment. Experimental studies have emphasized behavioral responses of narcissistic individuals to putative threats to status. Naturalistic and experimental studies suffer from opposing limitations, namely, a potential for confounding variables to impact results versus ambiguous generalizability to real-life and longer time scales, respectively. Integrating naturalistic and experimental studies has the potential to provide a comprehensive model of how dynamics within narcissism unfold in response to status threat. The current study examined shifts in grandiosity and vulnerability in both naturalistic (ecological momentary assessment) and experimentally controlled (rigged tournament game) social interactions (N = 437). Grandiosity decreased and vulnerability increased in response to both naturalistic and experimental status threats. Further, the same people who responded with decreased grandiosity in response to status threat in daily life, responded with similar decreases in grandiosity to experimental defeat. Trait narcissistic agency amplified many of the observed links between narcissism and status threat experimentally and naturalistically. The current study reinforces the importance of status threatening environments to expressions within narcissism and elucidates important differences with respect to expressions of grandiosity and vulnerability across naturalistic and experimental methods.
Feeling connected to nature: Validation of the Connectedness To Nature Scale in the Italian Context

Environmental issues are at the centre of the political and cultural debate, representing one of the greatest challenges of our century. Sustainability and pro-environmental conducts are rec-ognized as increasingly urgent to address the decay of ecosystems. To support the acquisition of attitudes that give greater consideration to environmental issues, feeling connected to nature has been acknowledged in psychology as a particularly relevant individual component. One of the most widely used scales in Anglo-Saxon context to analyse this feeling is the Connectedness to Nature Scale (CNS) measuring human’s affective and experiential connection to nature. To in-vestigate the psychometric properties of this scale in the Italian context, a study including 284 Italian adults (45,9% female; 54.1% males; Mean age = 34.63; SD = 13.422; age-range = 18-65 years) was carried out to provide evidence for the internal consistency of the CNS as well as its con-vergent, discriminant, and predictive validity. A Confirmatory Factor Analysis showed that CNS in Italian has a single-factor structure as reported in the original version by [1]. Further-more, as expected, positive correlations were observed between the CNS and pro-environmental attitudes and negative correlations with civic moral disengagement. Finally, as assumed, the CNS positively correlated with mental well-being. A broad vision of this study concerns the idea that if people are more connected to nature, they will be less inclined to harm it.
What I Do and What I Can Do: Testing the Convergence and Incremental Validity of Social, Emotional, and Behavioral Skills vs. Traits for Predicting Academic Success
Authors: Soto Christopher J. , Napolitano Christopher , Roberts Brent , Sewell Madison Nicole , Yoon Heejun Roy
Published: May 2023

The present research examined relations between social, emotional, and behavioral (SEB) skills, personality traits, and academic success in a sample of adolescents (N = 975). Results indicated that both skills and traits robustly predicted school grades, educational aspirations, and performance on a standardized achievement test, even after accounting for demographic characteristics. Moreover, skills and traits were often interchangeable: when assessed using the same cognitive, affective, and behavioral referents, they converged strongly and did not provide incremental validity over each other for predicting most outcomes. However, skills provided some incremental validity beyond traits for predicting standardized test performance. Taken together, these findings highlight the importance of SEB skills and personality traits for predicting and understanding academic success.
Computational Insights to Acquisition of Phonemes, Words, and Word Meanings in Early Language: Sequential or Parallel Acquisition?
Authors: Khorrami Khazar , Blandón María Andrea Cruz , Räsänen Okko
Published: May 2023

Previous computational models of early language acquisition have shown how linguistic structure of speech can be acquired using auditory or audiovisual learning mechanisms. However, real infants have sustained access to both uni- and multimodal sensory experiences. Therefore, it is of interest how the uni- and multimodal learning mechanisms could operate in concert, and how their interplay might affect the acquisition dynamics of different linguistic representations. This paper explores these questions with a computational model capable of simultaneous auditory and audiovisual learning from speech and images. We study how the model’s latent representations reflect phonemic, lexical, and semantic knowledge as a function of language experience. We also test how the findings vary with differential emphasis on the two learning mechanisms. As a result, we find phonemic learning always starting to emerge before lexical learning, followed by semantics. However, there is also notable overlap in their development. The same pattern emerges irrespectively of the emphasis on auditory or audiovisual learning. The result illustrates how the acquisition dynamics of linguistic representations are decoupled from the primary learning objectives (mechanisms) of the learner, and how the emergence of phonemes and words can be facilitated by both auditory and audiovisual learning in a synergetic manner.
A computational model of responsibility judgments from counterfactual simulations and intention inferences
Authors: Wu Sarah A , Sridhar Shruti , Gerstenberg Tobias
Published: May 2023

How responsible someone is for an outcome depends on what causal role their actions played, and what those actions reveal about their mental states, such as their intentions. In this paper, we develop a computational account of responsibility attribution that integrates these two cognitive processes: causal attribution and mental state inference. Our model makes use of a shared generative planning algorithm assumed to approximate people's intuitive theory of mind about others' behavior. We test our model on a variety of animated social scenarios in two experiments. Experiment 1 features simple cases of helping and hindering. Experiment 2 features more complex interactions that require recursive reasoning, including cases where one agent affects another by merely signaling their intentions without physically acting on the world. Across both experiments, our model accurately captures participants' counterfactual simulations and intention inferences, and establishes that these two factors together explain responsibility judgments.
