Mixed reality headsets typically include synchronized front-facing cameras that, among other things, can be used to track tracer particles (such as snowflakes) to estimate particle velocity field in real time. The current work presents a 3D particle tracking velocimetry method for use with MR devices, which combines binocular disparity and various monocular cues to estimate particle distance from an observer. This distance information is then incorporated into a particle tracking velocimetry algorithm to generate a three-dimensional visualization of the particle velocities. The resulting mixed reality particle tracking velocimetry (MR-PTV) approach was initially tested using synthetic particle data obtained by discrete element method simulations, resulting in a detailed error assessment of the method. The approach was then experimentally validated for particles transported in a wind tunnel and in a water flume flow using the Microsoft HoloLens 2 MR headset to image the particle motion. The resulting MR-PTV system can be used for mixed reality particle velocity visualization in a variety of industrial, scientific, and recreational purposes.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":54756,"journal":{"name":"Journal of Visualization","volume":"13 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A three-dimensional liquid-piston compressor model was established and validated against the experimental data. Two-phase flow was simulated using the finite volume method and the volume of fluid model in ANSYS Fluent software. A novel heat transfer enhancement technique using cooling pipes was investigated inside a liquid-piston compressor to achieve near-isothermal compression. Multiple cooling scenarios were explored to enhance the compression and thermal performance, considering the number of pipes, cross-sectional shape, diameter, and pipe temperature. This approach provided a more comprehensive understanding of the flow regimes and heat transfer behaviors of working fluids throughout the compression process. To achieve the desired pressure ratio, using four circular pipes reduced the hydrogen temperature from 394.2 to 355 K, marking 40.8% improvement in thermal efficiency. Furthermore, compression performance reached 95.8% with a power density of 3221.4 kW·m<sup>−3</sup>, compared to 90.9% and 4550.6 kW·m<sup>−3</sup> without cooling.</p><h3 data-test=\"abstract-sub-heading\">Graphic Abstract</h3>\u0000","PeriodicalId":54756,"journal":{"name":"Journal of Visualization","volume":"75 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various DR methods have been developed to extract specific features of the data over the years. However, selection of the optimal DR method and fine-tuning parameters are still challenging, as these choices vary based on the characteristics of the dataset. Consequently, data scientists often rely on their experience or undertake extensive experimentation to identify the most suitable approach. This paper proposes a semi-automatic method for selecting appropriate DR techniques through scatterplot evaluation. Initially, our approach applies a range of DR methods to the given multidimensional data to compute two-dimensional values. Next, we generate scatterplots from the two-dimensional data and calculate scores reflecting the distribution and spatial relationships among the points. Scatterplots that provide insights achieve higher scores, enabling an efficient selection of DR methods based on their visualization.

One is robust SPPIV which incorporates with robust Kalman filter and eliminates the outliers, while the other is multiresolution SPPIV which adopts the large interrogation area for real-time measurements and projects it into the high-resolution velocity fields. Robust and multiresolution SPPIV can estimate the velocity fields more accurately than high-resolution standard SPPIV with <span>(16 times 16)</span> or <span>(8 times 8;text {pixel}^2)</span> interrogation windows.

Hierarchical graph layouts efficiently provide an overview of large-scale graphs, where nodes form clusters (called metanodes in this paper) based on their properties. Here, it is challenging to determine layouts for large-scale graphs, particularly hierarchical ones. Although various graph layout drawing methods, such as force-directed layout, have been discussed so far, the quality of a layout heavily relies on the initial positions of nodes or metanodes. Furthermore, it is more challenging to obtain layouts where specific desired metanodes stand out. This paper presents a layout optimization method for hierarchical graphs using a genetic algorithm (GA). Our method allows for the consistent improvement of layouts compared to relying solely on an existing algorithm for generating hierarchical graph layouts. In our implementation, first, hierarchical graph layouts are generated by applying an existing algorithm multiple times. Then, they are evaluated by specific metrics for hierarchical graph layouts and optimized using GA. Consequently, optimal layouts for these metrics are obtained. The paper also presents particular examples of layouts optimized under different conditions using a co-authorship graph dataset.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":54756,"journal":{"name":"Journal of Visualization","volume":"108 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various types of visualizations have been proposed that take this spatio-temporal nature of the data into account, but it is unclear how well each one can be interpreted and whether such interpretation depends on the question asked about the data or the nature of the dataset that is being visualised. In this study, four spatio-temporal visualization techniques for eye movements (chord diagram, scan path, scarf plot, space-time cube) were compared in a user study. Participants <span>((N = 25))</span> answered three questions (what region first, what region most, which regions most between) about each visualization, which was based on two types of datasets (eye movements towards adverts, eye movements towards pairs of gambles). Accuracy of the answers depended on a combination of the dataset, the question that needed to answered, and the type of visualization. For most questions, the scan path, which did not use area of interest (AOI) information, resulted in lower accuracy than the other graphs. This suggests that AOIs improve the information conveyed by graphs. No effects of experience with reading graphs (for work or not for work) or education on accuracy of the answer was found. The results therefore suggest that there is no single best visualisation of the spatio-temporal aspects of eye movements. When visualising eye movement data, a user study may therefore be beneficial to determine the optimal visualization of the dataset and research question at hand.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":54756,"journal":{"name":"Journal of Visualization","volume":"4 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The light intensity decreased by 12.75% over 35 jet impingements (Ma = 0.7–1.2) without adjusting the light source power. The paint is calibrated and found to have a response time of 83 μs, a pressure sensitivity of 0.5833%/kPa, and a temperature sensitivity of 1.9%/K at 20 °C. The experiment is conducted in an anechoic chamber to investigate the effect of vertical jet impingement on a flat plate with impingement distances (<i>L</i>/<i>d</i>) ranging from 2 to 5. The PSP system captured dynamic pressure signals with a frequency of up to 9212 Hz (<i>L</i>/<i>d</i> = 2). Analysis of the surface pressure distribution in a period showed that an alternating axisymmetrical ring structure is formed in the periphery due to the interaction of expansion and compression waves at the impingement center. The evolving radius of the ring structure over time indicated that its outward expansion speed initially increases and then decreases. The proposed PSP measurement system provides technical assistance for investigating noise mechanisms in close-range vertical jet impingement.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":54756,"journal":{"name":"Journal of Visualization","volume":"11 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
