Investigating the synergy of blockage ratio and external cold heat exchanger in standing-wave thermoacoustic engines: An experimental study

Thermoacoustic engines (TAE) offer a promising avenue for converting low-grade heat into useable energy. Despite its simplicity in fabrication, designing thermoacoustic engines face efficiency challenges hindering their widespread adoption. One key obstacle faced by current thermoacoustic devices is their lack of efficiency. The core components of TAE are the stack, Cold Heat Exchanger (CHX), Hot Heat Exchanger (CHX) and the resonator. These components are crucial in advancing the performance of thermoacoustic engines. The CHX keeps the working gas cool, which is essential for the engine to function efficiently and create the desired acoustic wave. However, many existing efforts in this field have not taken into consideration the effect of the CHX design which may have effect on the operating temperature and the engines performance. This study examines the influence of different CHX blockage ratios (28 %, 36 %, 42 %, 47 %, and 59 %), along with the addition of an external CHX, on performance metrics. Measurements were conducted using air at room temperature and atmospheric pressure to assess temperature difference, startup time, volumetric velocity, and sound pressure levels. Key findings indicate that Efficiency directly correlates with volumetric velocity and inversely with onset temperature. Even though decreasing the blockage ratio increases operating temperature, it lengthens startup and reduces volumetric velocity, suggesting increased axial conduction. In addition, External CHX lowers operating temperature, reducing volumetric velocity and sound pressure. Interestingly, resonance frequency remains unaffected by CHX blockage ratio changes. An optimal configuration with a 42–47 % blockage ratio achieves 5.92 m/s velocity, 136 s startup time, and 77 °C onset temperature. These findings offer valuable insights for optimizing thermoacoustic engine efficiency and advancing their potential as sustainable energy solutions.

Gender Differences in Math Tests: the Role of Time Pressure

Abstract We investigate the role of time pressure in generating gender gaps in math tests. In a randomised experiment, college students took a twenty-question math test under high, low or no time pressure. Reducing or eliminating time pressure decreases the math gender gap by up to 40%. Larger gaps under time pressure are mostly due to increased anxiety rather than to students modifying their test-taking strategies. The correlation between math test scores and university performance is equally high under the different scenarios. Hence, less time pressure may increase gender equality in math subjects with no effect on the selection process.

How does organizational polychronicity relate to individual adaptive performance? A conservation of resources perspective

PurposeThis study aims to examine the effects of organizational polychronicity on individual adaptive performance. Drawing on conservation of resources theory and the perspective of individual differences in pressure perceptions, this study develops a conceptual model to test the mediating role of time pressure and the moderating role of trait regulatory focus in the relationship between organizational polychronicity and individual adaptive performance.Design/methodology/approachA three-wave survey was conducted to investigate a sample of 591 employees who engaged in innovative activities in China. The hypotheses were tested using hierarchical multiple regression and bootstrapping.FindingsThe results show that organizational polychronicity is negatively related to individual adaptive performance via time pressure. Promotion focus weakens the positive relationship between organizational polychronicity and time pressure and the mediating role of time pressure, while prevention focus augments the positive relationship between organizational polychronicity and time pressure and the mediating role of time pressure.Originality/valueThis study reveals the mediating role of time pressure in the relationship between organizational polychronicity and individual adaptive performance, as well as the moderating role of trait regulatory focus in this relationship, thereby deepening our understanding of organizational polychronicity from both a theoretical and a practical perspective.

The Influence of Marketing Stimulation and Situational Factors on Impulse Purchasing Behavior of Vietnamese Consumers

Today, with the increasingly improved standards of living, consumers’ demands are becoming more diverse. As daily purchasing activities are becoming less planned, impulse purchases are increasingly the norm. This paper focuses on factors influencing consumers’ impulse purchase behavior in three of Vietnam’s largest cities (Hanoi, Da Nang and Ho Chi Minh) based on a review of previous research as well as an analysis of effects of marketing stimuli and situational factors. Data were obtained from 264 Vietnamese consumers who have made impulse purchases using an online survey. Hypothesis testing and path modeling demonstrated that among four marketing stimuli factors, except for price incentives, all have a significant positive impact on impulsive purchase behavior. In addition, time pressure and ability to pay have a significant impact on impulsive purchase behaviors of urban Vietnamese consumers. These findings enrich the extant knowledge on the relationship between marketing stimulation, situational factors and impulse purchasing behavior. They also have important implications for firms that aim to stimulate changes in consumers' psychological desires, thereby stimulating consumers to engage in impulsive purchase behavior.

Innovating in an Uncertain World: Understanding the Social, Technical and Systemic Barriers to Farmers Adopting New Technologies

The current geopolitical and socioeconomic landscape creates a difficult and uncertain operating environment for farming and agri-food businesses. Technological innovation has not been suggested to be a “silver bullet” but is one of the ways organizations can seek to reduce environmental impact, deliver net zero, address the rural skills and labor deficit and produce more output from fewer resources and as a result, make space for nature. But what barriers limit this promissory narrative from delivering in practice? The purpose of the paper is to firstly explore the reported social, technical and systemic barriers to agri-technology adoption in an increasingly uncertain world and then secondly identify potential research gaps that highlight areas for future research and inform key research questions. Socio-technical and infrastructural barriers have been identified within the context of the complex hollowing out and infilling of rural communities across the world. These barriers include seventeen factors that emerge, firstly those external to the farm (economic conditions, external conditions including bureaucracy, market conditions, weather uncertainty and the narratives about farmers), those internal to the farm business (farming conditions, employee relations, general finance, technology and time pressures) and then personal factors (living conditions, personal finances, physical health, role conflict, social isolation and social pressure). Adaptive resilience strategies at personal, organizational and community levels are essential to address these barriers and to navigate agri-technology adoption in an uncertain and dynamic world.

Evaluating a grant development public involvement funding scheme: a qualitative document analysis

BackgroundUndertaking Patient and Public Involvement (PPI) when developing health and social care research grant applications is critical. However, researchers may not have any funding to undertake PPI when developing grants. In response, the National Institute for Health and Care Research- Research Design Service for Yorkshire and the Humber in the United Kingdom, provided Public Involvement Fund Awards of up to £600 to fund PPI activity when researchers were developing grant applications. Researchers provided post-activity reports about how they utilised the Public Involvement Fund. These reports were analysed with the aim of evaluating the usefulness of the Public Involvement Fund and to provide learning about supporting researchers to undertake PPI when developing grants.MethodsThe project was a qualitative document analysis of 55 reports. Initially a researcher coded four reports and three Public Contributors provided feedback. Researchers coded the remaining reports and identified key findings. A workshop was held with the three Public Contributors to develop the findings.ResultsResearchers accessing the Public Involvement Fund award were generally early career researchers or clinicians who did not have other sources of funding for pre-grant PPI input. Researchers felt the award was useful in enabling them to conduct PPI, which strengthened their grant applications. Some researchers found that the award limit of £600 and guidance encouraging expenditure within three months, made it difficult to undertake PPI throughout the full grant development process. Instead, the majority of researchers consulted Public Contributors on one or two occasions. Researchers struggled to recruit diverse members or run group sessions due to the time pressures of grant deadlines. Researchers wanted training on undertaking PPI alongside the financial support.ConclusionsResearchers, especially early career researchers found having a Public Involvement Fund award instrumental in enabling them to undertake PPI when developing grant applications. It would be beneficial for similar schemes to be widely available. Schemes need to provide sufficient funding to enable meaningful PPI and allow researchers to hold the award for long enough to facilitate involvement during the whole grant development process. Researchers continue to need training on undertaking PPI.

Interrogating an implementation filter: what constrains changes in teacher practice in response to professional development

ABSTRACT It is well known that teacher professional development may not result in meaningful change to classroom instruction. A recent theoretical model by McChesney and Aldridge (2021) posited that this phenomenon may be explained on account of ‘implementation barriers’ to professional development delivery. The present study thus investigated the nature, structure, and distribution of such barriers to the impact of teacher professional development on classroom practice. Using survey data collected from three Illinois school districts (N = 274), we identified six distinct but non-orthogonal barriers (e.g. school culture, relevance, teacher resistance) and found that the most commonly perceived specific implementation barriers were time constraints and pressures, other curricular mandates or demands, and stress or burnout. Repeated-measures analysis of variance also showed some differences in the profiles of the six barriers across the school districts.

Exploring the Educational Efficacy and Potential of 24-Hour Hackathon Programming Marathon – HackEmotion

This paper addresses the issue of modern didactics and student motivation for self-learning as well as tackling significant practical challenges. In technical and STEAM education, achieving high levels of motivation is particularly important, as students often become overwhelmed by the vast amount of information and opportunities which lead to diminished interest. At the Institute of Computer Science at the University of Silesia in Katowice, a Hackathon – a 24-hour programming marathon – was organized to enhance student engagement. During this event, students confronted a critical problem in modern societye: emotion recognition. The goal was to develop solutions and help for fostering emotion recognition skills in young people with real-world implementation potential. Additionally, students tested their abilities under time pressure, honed their group work competencies, and faced real-time problem-solving scenarios. This paper presents an evaluation of the event’s impact and analyzes the results of a post-event survey, providing feedback to improve the quality of future Hackathons. The main research questions we posed during the research were: RQ1: At what level of quality was the Hackathon event organized? Whether students were well informed and felt cared for during this event? RQ2: What aspects and properties motivate students most to take part in events organized at the university like Hackathon? RQ3: What competencies, knowledge and skills were developed by participants in the Hackathon? RQ4: Do students consider issues related to recognizing emotions important and the created applications possible to use in practice? In this paper, we answer these questions using statistical analysis as well as simple machine learning models.

Design and Implementation of Tire Pressure and Temperature Monitoring System for Hatchback and Multi-Purpose Vehicle Based on IoT

Tire Pressure Monitoring Systems (TPMS) have developed into an essential element in vehicles to improve safety and driving experience. In general, TPMS systems rely on special hardware to collect and transmit tire pressure data to the vehicle's on-board computer and this data can only be viewed by the driver and passengers in the vehicle. In this study, we developed a remote tire pressure and temperature monitoring system using IoT technology. The MQTT protocol facilitated communication between the cloud server and controller, while the system uses Docker container to simplify program integration. The results revealed the optimal standard deviation for tire pressure in hatchback vehicles to be 2.24, and for Multi-Purpose Vehicles (MPVs), it was 2.97. For tire temperature, the best standard deviation in hatchback vehicles was 1.93, compared to 1.05 in MPVs. This system effectively monitors tire pressure and temperature changes in real time, accessible remotely via smartphones and computers.

How Time Pressure Modulates Individual Differences in the Functional Connectivity of Chunk Memory in Chess Games

Previous studies on the chess game demonstrated that chess experts strongly rely on the activation of memory chunks to manifest accurate decision-making. Although the chunk memory might be affected by temporal constraints, it is unclear why the performance of chess experts is not significantly dropped under time pressure. In this study, our objective is to examine the variations in cognitive neural mechanisms between chess experts and novices under time pressure. The underlying cognitive neural mechanism was carefully inspected by accessing the chess game performance between 20 local experienced and 20 inexperienced chess players with 1-minute and 5-minute time constraints. In addition, functional near-infrared spectroscopy (fNIRS) recordings were carried out for each individual from the two groups while playing a 1-minute or 5-minute chess game. It was discovered that under temporal constraints, players exhibited different patterns of functional connectivity in frontal-parietal regions, suggesting that temporal stress can enhance segmentation processes in chess games. In particular, the experienced group exhibited significantly enhanced functional connectivity networks under time pressure including the dorsolateral prefrontal cortex, inferior frontal gyrus, supramarginal gyrus, and postcentral gyrus, which demonstrated the important role of the segmentation process for experienced players under time pressure. Our study found that experienced players were able to enhance recall, reorganize, and integrate chunks to improve chess performance under time pressure.

Recent stressful life events and identity development in emerging adults: An examination of within-person effects.

To examine longitudinal associations among stressful life events and identity processess in emerging adults while accounting for within-person and between-person effects. Theoretical perspectives suggest that stressful life events may impact one's identity (i.e., coherent sense of self), but few studies have considered how changes in stressful life events are associated with changes within an individual's identity development over time (within-person effects). Recent stressful life events (i.e., academic problems, friendship problems, romantic problems, and time pressure) and the processes through which identity develops (e.g., exploring in breadth and depth) were examined longitudinally (T1-T3) in a sample of emerging adults (N = 1125, Mage = 17.96 years). Random-intercept cross-lagged modeling demonstrated that at the between-person level, emerging adults with greater academic and friendship problems, as well as more time pressures (relative to their counterparts), tended to engage in greater ruminative exploration. Further, those with more academic problems tended to demonstrate weaker commitment-making and exploration in breadth and depth (relative to their counterparts). Within-person increases in romantic problems predicted lower commitment-making and higher ruminative exploration over time. Findings suggest that romantic problems may predict within-person changes in identity processes, whereas academic problems, friendship problems, and time pressure may be more concurrently related to identity development.

Time pressure increases children's aversion to advantageous inequity.

The relative contribution of intuitive and reflective cognitive systems in cooperative decision making is a topic of hot debate. Research with adults suggests that intuition often favors cooperation, but these effects are contextually sensitive. Emerging evidence has shown that in many contexts children show a tendency toward intuitive cooperation, but research investigating these processes in children is sparse and has produced mixed findings. In the current study we investigated the influence of intuitive and reflective decision processes on children's fairness behavior by manipulating decision time. We tested (N = 158) pairs of children between 4 and 10 years of age from a rural community in Canada. Children's decisions to accept or reject allocations of candies were either made under time pressure or after a 10-s delay. We assessed the impact of decision time on children's aversion to inequitable distributions of resources by comparing their responses to equal allocations with either disadvantageous allocations or advantageous allocations. We found that children showed a greater age-related increase in advantageous inequity aversion when decisions were made under time pressure compared to when they were made after a delay. In contrast, we did not observe a significant impact of decision time on the development of disadvantageous inequity aversion. These findings suggest that intuitive decision processes may contribute to the development of fairness concerns in middle childhood.

A Phenomenological Inquiry on the Research Engagement of Tertiary Instructors in a Philippine State College

Research engagement among tertiary instructors is crucial in advancing knowledge, enhancing teaching practices, and driving innovation within higher education institutions. This study explored on the engagement of tertiary instructors in research. A qualitative study, particularly phenomenological inquiry, was used. Through purposive sampling, 22 tertiary instructors served as participants for this phenomenological study. Five themes unfolded as the lived experiences of tertiary instructors with regards to their research engagement: advancing knowledge along the institutional research journey, navigating multiple responsibilities under time pressure, and ensuring research feasibility despite budget challenges. Regarding the coping mechanisms employed by tertiary instructors in their research engagement, four themes emerged: keeping abreast through research enrichment sessions, conducting research through interdisciplinary collaboration, framing research topics with practical relevance, and refining research engagement through active feedback. Further, three themes emerged as the insights of tertiary instructors regarding their research engagement: enhanced scholarly drive empowers faculty research, research illuminate pathways for educational advancement, and time and commitment fuel faculty research engagements. The study concludes with recommendations for higher education institutions to promote and sustain robust research engagement among tertiary instructors, ultimately contributing to the advancement of knowledge and the mission of higher education.

The mechanochemistry of lanthanum dihydride (LaH\(_{2}\)) with hydrogen (H\(_{2}\)) using the ball-mill process and the effect of oxidation on the resulting products

The complex behavior of LaH2 during ball milling was investigated in this study, with its mechanical, chemical, and morphological changes explored. The relationship between milling time and hydrogen pressure reduction was uncovered through detailed experiments, reflecting the dynamic nature of the process. A transient yet significant event was observed upon unsealing the milling jar post-milling: the emergence of a minor fire ember, indicative of the interplay between mechanical forces and chemical reactivity within the LaH2 powder. Profound changes in the structure, composition, and shape were unraveled using advanced techniques such as X-ray diffraction (XRD), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDX), and particle size distribution analysis. The resulting powder exhibited a dual-phase composition of lanthanum dihydride (LaH2, 68.1% to 71.5%) and lanthanum oxide (La2O3, 28.5% to 31.9%), reflecting a dynamic chemical equilibrium during milling. Particle size distribution analysis revealed a notable increase in average diameter to 6420 nm, accompanied by a polydispersity index (PDI) of 0.831, signifying a broadening compared to the initial LaH2 powder. The morphological evolution of the powder was elucidated through SEM imaging, showing predominantly spherical and rounded forms, indicating extensive particle agglomeration and plastic deformation during milling. Additionally, the formation of oxide layers on the powder surface, intertwined with pronounced particle agglomeration, was highlighted through EDX mapping, shedding light on the mechanical aspects of morphological evolution during milling. These findings contribute to our understanding of LaH2 behavior under extreme mechanical and chemical conditions and have implications for materials processing, hydrogen storage technologies, and broader applications in materials science and engineering.

The impact of knowledge characteristics on process performance: experimenting with the conversion perspective on knowledge transfer velocity

PurposeWith shorter product cycles and a growing number of knowledge-intensive business processes, time consumption is a highly relevant target factor in measuring the performance of contemporary business processes. This research aims to extend prior research on the effects of knowledge transfer velocity at the individual level by considering the effect of complexity, stickiness, competencies, and further demographic factors on knowledge-intensive business processes at the conversion-specific levels.Design/methodology/approachWe empirically assess the impact of situation-dependent knowledge transfer velocities on time consumption in teams and individuals. Further, we issue the demographic effect on this relationship. We study a sample of 178 experiments of project teams and individuals applying ordinary least squares (OLS) for regression analysis-based modeling.FindingsThe authors find that time consumed at knowledge transfers is negatively associated with the complexity of tasks. Moreover, competence among team members has a complementary effect on this relationship and stickiness retards knowledge transfers. Thus, while demographic factors urgently need to be considered for effective and speedy knowledge transfers, these influencing factors should be addressed on a conversion-specific basis so that some tasks are realized in teams best while others are not. Guidelines and interventions are derived to identify best task realization variants, so that process performance is improved by a new kind of process improvement method.Research limitations/implicationsThis study establishes empirically the importance of conversion-specific influence factors and demographic factors as drivers of high knowledge transfer velocities in teams and among individuals. The contribution connects the field of knowledge management to important streams in the wider business literature: process improvement, management of knowledge resources, design of information systems, etc. Whereas the model is highly bound to the experiment tasks, it has high explanatory power and high generalizability to other contexts.Practical implicationsTeam managers should take care to allow the optimal knowledge transfer situation within the team. This is particularly important when knowledge sharing is central, e.g. in product development and consulting processes. If this is not possible, interventions should be applied to the individual knowledge transfer situation to improve knowledge transfers among team members.Social implicationsFaster and more effective knowledge transfers improve the performance of both commercial and non-commercial organizations. As nowadays, the individual is faced with time pressure to finalize tasks, the deliberated increase of knowledge transfer velocity is a core capability to realize this goal. Quantitative knowledge transfer models result in more reliable predictions about the duration of knowledge transfers. These allow the target-oriented modification of knowledge transfer situations so that processes speed up, private firms are more competitive and public services are faster to citizens.Originality/valueTime consumption is an increasingly relevant factor in contemporary business but so far not been explored in experiments at all. This study extends current knowledge by considering quantitative effects on knowledge velocity and improved knowledge transfers.

P‐70: A Novel Peak Luminance Correction Method Based on Global IR Drop Compensation System on AMOLED

In the past year, AMOLED have been widely used in smartphones, laptops, and vehicles. Local excitation luminance is one of the important parameters to measure AMOLED quality. This feature is of great significance for realization of HDR video and getting better visual experience in sunlight environment. Due to IR drop effect in the local display, the performance of peak luminance is often skewed by luminance, chrominance, and gamma curves. The solution is adding a set of Gamma curve debugging at peak luminance of local display, which results in longer take time (TT) and greater aging pressure at high luminance. In this paper, we propose a novel peak luminance correction method based on Global IR (GIR) voltage drop compensation system. In the compensation system, GIR compensation Look‐Up Tables (LUT) is used to accurately tune the luminance, chrominance, and gamma curves that correspond to the local excitation luminance.

Influences of preheating parameters on the quality of weld by thermite rail welding

The major goal of this study is to enhance the mechanical and metallurgical characteristics of rail steel grade R260 joined by thermite welding under various preheating conditions, including preheating time and gas pressure. Mainly two conditions, referred to as the Normal Condition and Improved Condition, are carried out for experiments. Prior to welding, the Normal Condition was preheated using liquefied petroleum gas (LPG) and oxygen gas pressures of 1 bar and 4.5 bar for 3 min, and the Improved Condition was preheated using liquefied petroleum gas and oxygen gas pressures of 1.2 bar and 4.5 bar for 6 min and 30 s. To investigate the mechanical and physical properties, micro-Vickers hardness tests, tensile tests and slow bending tests were also carried out. Welded metal in Normal Condition has many defects, including gas holes and shrinkage cavities. When comparing the Normal Condition to the Improved Condition, the Improved Condition demonstrates significantly more bending load and deflection. Specifically, the thermite welded rail sample of Improved Condition demonstrated a remarkable ability to endure bending loads of 108 tonnes and a deflection of 16 mm, and this sample remained unbroken until it exceeded 50% of the standardized deflection limit (10 mm). In addition, the average hardness values for the Improved Condition of the weld metal zone and the heat-affected zone were 331 HV and 289 HV, respectively. The Normal Condition produced an unsatisfactory fracture surface after slow bending test. This was caused by weld defects at the thermite weld due to inappropriate preheating.
