Yellowstone Volcano Observatory 2021 annual report

First posted April 27, 2022 For additional information, contact: Contact YVOVolcano Science Center, Yellowstone Volcano ObservatoryU.S. Geological Survey345 Middlefield Road, MS 910Menlo Park, CA 94025 The Yellowstone Volcano Observatory (YVO) monitors volcanic and hydrothermal activity associated with the Yellowstone magmatic system, carries out research into magmatic processes occurring beneath Yellowstone Caldera, and issues timely warnings and guidance related to potential future geologic hazards. This report summarizes the activities and findings of YVO during the year 2021, focusing on the Yellowstone volcanic system. Highlights of YVO research and related activities during 2021 include deployments of seismometers in Norris Geyser Basin and Upper Geyser Basin to investigate geyser plumbing systems, semipermanent Global Positioning System array deployment from May to October, geological studies of post-glacial hydrothermal activity, refining the ages of Yellowstone volcanic units and updating existing maps of geologic deposits, installation of a new continuous gas monitoring station near Mud Volcano, sampling of thermal waters around Yellowstone National Park to monitor water chemistry over space and time, and assessment of thermal output based on satellite imagery and chloride flux in rivers.Steamboat Geyser, in Norris Geyser Basin, continued the pattern of frequent eruptions that began in 2018 with 20 water eruptions in 2021—a significant decrease from the 48 eruptions that occurred in both 2019 and 2020. Total seismicity—2,773 located earthquakes—was elevated compared to the 1,722 earthquakes located in 2020, but not significantly outside the historical average of about 1,500–2,500 earthquakes per year. Overall subsidence of the caldera floor, ongoing since late 2015 or early 2016, continued at rates of a few centimeters (1–2 inches) per year, whereas deformation in the Norris Geyser Basin area was below detection levels. Satellite deformation measurements indicate the possibility of slight uplift amounting to about 1 centimeter (less than 1 inch) along the north caldera rim, south of Norris Geyser Basin. The deformation is similar to that which occurred in the late 1990s. Throughout 2021, the aviation color code for Yellowstone Caldera remained at “green” and the volcano alert level remained at “normal.”
Implementation of Efficient Online English Learning System and Student Performance Prediction Using Linear K-Nearest Neighbors (L-Knn) Method

Technical assistance for the establishment of a distance learning environment for learning English is provided by the advancement of information technology and the educational information process. People are still getting used to online teaching methods, and it is becoming more widely accepted. E-learning and online education have advanced significantly in recent years. The teaching paradigm has moved from traditional classroom learning to dynamic web-based learning. As a result, instead of static information, learners have received dynamic learning material tailored to their abilities, requirements, and preferences. To improve the English learning material efficiency, this paper implements an online English learning system based on efficient learning material selection. The English learning materials are preprocessed using normalization. The dimensionality reduction of the data is done using the Kernel-based-Independent Component Analysis (K-ICA). Data classification is performed using the Hypothetical Naïve Bayes Algorithm (HNBA). The student performance like learning efficiency, interactive accuracy rate, and artistic skills are predicted using the linear k-Nearest Neighbors (L-KNN). The proposed system can be simulated by employing the MATLAB tool and the performance is compared with other conventional methodologies. The findings of this study reveal that the presented online learning method may significantly increase students' oral and written skills.
Research on Power Data Imaging and Compression-Reconstruction Algorithm

With the further construction of strong smart grid, a large amount of power data has been generated, which needs to be stored and visualized to facilitate the subsequent analysis of the power system. Aiming at the problems that the traditional power data visualization method is not suitable for the emerging deep learning model and the power system data storage capacity does not match the data acquisition and transmission capability, power data imaging and power data image compression-and-reconstruction method based on embedded zero-tree wavelet image coding is proposed. In power data imaging, HSV color space is used to construct two-dimensional pixel images of power data; In the image compression-and-reconstruction mechanism, the embedded zero-tree wavelet coding is used to compress and decompress the power data image by combining the zero-tree structure with SAQ. Case studies show that the proposed method can effectively visualize power load data, realize effective data compression, reduce data storage pressure, and achieve accurate image reconstruction.

This chapter gives a brief view over the social networks humans created and the changes came with information technologies. In this chapter, we will examine the social networks created and used by humans in the past and their alternations with information technologies. This chapter will give an overview over the tools in analysing social media networks and as an example we will examine sentiment analysis approaches, models and tools.
Production System Modelling Methodologies of an Open Pit Mine

Open pit mines experience several challenges and constraints in the management of mining operations and processes. The heterogeneity of the infrastructures and the complexity of the physical and managerial systems highlight these various challenges. The creation of a generic system that can drive but at the same time models in a dynamic logic all these constraints and elements assume a major complexity. In addition, the modelling allows the implementation of real-time decision-making components and increases the responsiveness of the system. This paper presents six modelling methodologies of the production system, namely Open System Architecture for Computer Integrated Manufacturing, GRAI Integrated Methodology, Purdue Enterprise Reference Architecture, Generalized Enterprise Reference Architecture and Methodology, Zachman and Model Based System Engineering. Based on the multi-criteria analysis, we have shown that the Modelling Based System Engineering is the most adapted methodology in the case of open pit mines but this method knows a lack of agility in the system. Our system will use a methodology based on Model Based System Engineering and will consider the agility of the system.

The Use of MAF and BLAF Analytical Tools in Assessing Business Communication Texts

This paper provides a vivid explanation of two analytical frameworks I designed for grading business communication texts.These frameworks are Memorandum Analytical Framework (MAF), and Business Letter Analytical Framework (BLAF).The paper, furthermore, provides a pedagogical guide about how MAF and BLAF are applied in the Second Language Acquisition (SLA) classrooms, and in the world of business.It is my hope that these two frameworks will not only serve as potent benchmarks for assessing business communication texts that learners generate in SLA classrooms but frameworks that regulators of businesses can depend on for maintaining standards in terms of presentation styles for letter and memo writing.The paper is segmented into four sections.The introduction presents the background information about the problem, grading of business communication texts (i.e.memos and business letters), and my justification for propounding these frameworks.The next section, analytical tools-MAF and BLAF, projects graphical representation of the frameworks, and explanation of the variables used.The third section, pedagogical application of MAF and BLAF, explains how MAF and BLAF are used in assessing business communication texts.The conclusion section summarizes the paper, and presents a statement of expectation concerning how stakeholders in SLA can utilize MAF and BLAF.
A Systematic Mapping Study of Search-Based Software Engineering for Enterprise Application Integration

Search-Based Software Engineering (SBSE) is widely used in different fields of Software Engineering, notoriously, in Enterprise Application Integrations (EAIs). EAI encompasses methodologies, techniques and tools that a software engineer can use to create integration solutions. SBSE is currently an active research topic of increasing interest. The number and diversity of publications produced yearly are large to the extent that it is hard to identify the active research groups, their locations, techniques used and research topics that have not received enough attention. To answer these questions categorically, we have conducted systematic mapping study of the literature. In this paper, we report our methodology and findings. In our study, we used systematic search strategies that resulted in the retrieval of 560 articles, of which we first selected 25. Second, on the basis of the authors’ experience, we included eight additional articles. Finally, we used a snowballing sample technique to include another 12 articles. The results demonstrate that during the last two decades (1999–2020) EAI has benefited from the use of Search-Based Software Engineering techniques.

Thus, substantial effort has been devoted to proposing new concurrency control algorithms in both the database industry and academia. In this paper, we take the lead in summarizing the fundamental ideas of concurrency control algorithms as ``ordering-and-verifying''. We then redescribe and sort out the existing concurrency control algorithms following the ordering-and-verifying paradigm. On the basis of extensive comparative experiments on an open-source main-memory distributed transaction testbed called 3TS, we systematically investigate the advantages and disadvantages of the mainstream concurrency control algorithms and finally summarize the preferable application scenario for each algorithm to provide valuable references for follow-up research on concurrency control algorithms used in main-memory databases.

English Verb Valency Pattern in Padma Resort Legian Guest Reviews on TripAdvisor

This research was conducted in order to identify verb valency pattern found in reviews on TripAdvisor uploaded by visitors of Padma Resort Legian. It was executed as a descriptive qualitative research which complied with observation and note-taking method for data collection (Sudaryanto, 2015), continued by data analysis in accordance with Verbs and Their Satellites theory by D.J. Allerton (2006). The sample data was taken from reviews posted for Padma Resort Legian in TripAdvisor. It was compiled and analyzed in Microsoft Excel pivot table. Most of the verb valency pattern found consists of auxiliary verb with subject and predicative as its elaborators functioning as object. In terms of its transitivity, verb valency patterns on reviews were dominated with bi-valent, followed by tri-valent, mono-valent and tetra-valent in number.
Virtual Immersion User Experience in Cave and Hmd: A Comparative Study

This paper proposes to analyze user experience when using two different categories of immersive devices: a Cave Automatic Virtual Environment (CAVE) and a Head-Mounted Display (HMD). Through this study, we want to highlight the differences in user experience induced when using either one of these technologies, in terms of navigation, visualization, presence, cybersickness and interaction. While most past studies focused on one of these devices to characterize user experience, we propose to fill the gap in comparative studies by conducting investigations using both devices, considering the same application, method and analysis. We performed three experiments, each focusing on a specific aspect of the devices employed. The first one is related to distance perception when walking, and the possible influence of the HMD’s weight, which does not occur with CAVE systems as they do not require wearing any heavy equipment. Past studies found indeed that weight may impact distance perception. Several walking distances were considered. Results revealed that the HMD’s weight does not induce significant differences over short distances (above three meters). In the second experiment, we focused on distance perception over short distances, as we considered that, the HMD’s screen being closer to the user’s eyes than in CAVE systems, it may induce strong distance perception differences, especially for short distance interaction. We designed a task in which users had to move an object from one place to another at several distances, using both the CAVE and an HMD. Results revealed significant underestimation compared to reality as in past work, but no significant differences between the immersive devices. In the third experiment, we investigated differences related to navigation in large virtual environments, the fundamental differences between a CAVE and an HMD being here the field of view (FOV) and the field of regard (FOR). As an HMD provides a wider FOR than a CAVE, navigation could be impacted in wide environments, thus our experiment involved movements requiring to use the whole FOR. Since this experiment also required users to get immersed for a long time, we also recorded physiological (heart-rate and skin conductance) and psychological data (virtual reality sickness questionnaire (VRSQ) and misery scale questionnaire (MISC)) to measure the cybersickness level. No significant difference between the devices was found in the cybersickness level according to the VRSQ, as well as in time completion, though higher scores for VRSQ, MISC and time completion were observed in the CAVE modality. Surprisingly, rotational movements and heart rate did not differ significantly between the devices. These results provide with a better understanding of the differences existing between two emblematic virtual reality displays.
