Bayesian Surface Warping Approach for Rectifying Geological Boundaries Using Displacement Likelihood and Evidence from Geochemical Assays

This article presents a Bayesian framework for manipulating mesh surfaces with the aim of improving the positional integrity of the geological boundaries that they seek to represent. The assumption is that these surfaces, created initially using sparse data, capture the global trend and provide a reasonable approximation of the stratigraphic, mineralization, and other types of boundaries for mining exploration, but they are locally inaccurate at scales typically required for grade estimation. The proposed methodology makes local spatial corrections automatically to maximize the agreement between the modeled surfaces and observed samples. Where possible, vertices on a mesh surface are moved to provide a clear delineation, for instance, between ore and waste material across the boundary based on spatial and compositional analysis using assay measurements collected from densely spaced, geo-registered blast holes. The maximum a posteriori (MAP) solution ultimately considers the chemistry observation likelihood in a given domain. Furthermore, it is guided by an a priori spatial structure that embeds geological domain knowledge and determines the likelihood of a displacement estimate. The results demonstrate that increasing surface fidelity can significantly improve grade estimation performance based on large-scale model validation.

Reinstating Traditional Horsemanship of Ethnic Minorities in Southern China by Excavation, Sorting, and Comparative Research

In August 1991, the book Chinese Nation’s Traditional Sports History was published, and it was hailed as the “masterpiece of Chinese folk sports” by academic circles. In this masterpiece, the traditional horsemanship of 23 ethnic minorities and that of 10 southern ethnic minorities represented by the Miao, Yi, Bai, Shui, Hani, Naxi, and other ethnic groups has been included. For the first time, this masterpiece integrates the traditional horsemanship of the ethnic minorities in Southern China in one volume. The disadvantage is that most of the included traditional horsemanship of ethnic minorities only made a brief introduction to the time, place, and form of its development. However, under the global trend of the transition from traditional society to modern society and post-modern society, the traditional horsemanship of ethnic minorities in Southern China is facing an increasingly serious crisis of inheritance and disconnection, resulting in a gradual extinction of related traditional cultural heritage. The characteristics are gradually lost because of it. Therefore, it is essential to return to the historical and cultural field of traditional horsemanship, conduct rescue excavation, sort out the traditional horsemanship of ethnic minorities in Southern China, rescue the records of traditional horsemanship that is disappearing or undergoing drastic changes, as well as carry out comparative studies on this basis. This is not only an important way to inherit the traditional culture of ethnic minorities, but also means to protect the diversity of ethnic cultures and promote the development of exotic villages.

America’s First Memorial Honoring Survivors of Sexual Violence

Over the past two decades, America taken part of a broader global trend of “memorial mania” in which memorials dedicated to remembering injustice have exploded into public space. Memorials that facilitate the centering of marginalized narratives of violence hold significant power for social change. This article focuses on one such space: The Survivors Memorial in Minneapolis, Minnesota. The Survivors Memorial opened in October 2020 and is the first public memorial honoring survivors of sexual violence. Despite the progress of the anti-rape and feminist movements as well as a variety of legal interventions designed to address sexual violence and empower, many survivors are left without a sense of justice or institutional or community recognition. Drawing on 21 in-depth, qualitative interviews with individuals involved in all aspects of the memorial project, this article documents how one community mobilized to create a space for survivors whose voices are often overlooked, disbelieved and silenced by the criminal justice system, practitioners, and communities. In focusing on how participants narrate the significance and meaning of the Survivors Memorial, this article uncovers how social, political, and local circumstances coalesced to make the Memorial possible. These factors include local leadership, the prevalence of sexual violence, the unique structure of the Minneapolis park structure, and the rise of the #MeToo movement. Interviews illuminate that participants worked to intentionally construct the Memorial as an accessible and visible space that centers on providing all sexual violence survivors with public acknowledgment of their experiences, while simultaneously engaging community members in dialogs about sexual violence, ultimately, laying the foundation for sexual violence prevention efforts.

Electronic Payment Performance

The increasing speed of e-payment adoption is driven by multiple factors: Generation Z (individuals born between 1990s to early 2010s), easy payment methods, open banking ecosystem, rewards incentive, network, and the onset of COVID-19 in 2020. The Malaysian government hopes through collaboration with banks and payments industries to reach a cashless society, leveraging on the existing infrastructure to accelerate the migration to e-payments. The problems that emerge in a cashless society and secured e-payment need to be well considered by the related parties, particularly the policymakers and regulators, to position Malaysia on the right path to embark on the most advanced global trend. Therefore, this chapter aims through contextual analysis to investigate the trend performance and social impact on secured electronic payment (e-payment) in Malaysia during the period of 2016-20.

Проблема вероисповедания бурят в трудах Ц. Ж. Жамцарано (1900-е гг.)

The article aims to analyze the issue of Buryat religious views as discussed in the works of Ts. Zhamtsarano in the 1900s. The purpose of the study is to identify the specifics of Zhamtsarano’s approach in the formulation of the research issue. In particular, the article analyzes the impact of his scientific and social activities on the course of his creative thought, as well as compares his interpretation of Buryat religious movement with that of M. N. Bogdanov, one of outstanding researchers of Buryat history. To analyze the impact of his cultural-historical environment on Zhamtsarano’s views, it was necessary to examine the scholar’s diaries he kept at the time of his ethnographic expeditions in Buryatia in 1903–1906 in comparison with his published works of the same period. As a result, it was possible to identify his key positions on the issue of the Buryat religious movement in the early twentieth century. Conclusions. The analysis of Zhamtsarano’s works shows that the Buryat religious movement had a long history, with its ethnoterritorial features gradually being formed. The reason for its acceleration in the 1900s was that many Buryats at the time were largely dissatisfied with their dominant religion, hence their search for new forms of spirituality. According to Zhamtsarano, the general direction of this movement was towards cultural pan-mongolism; this conclusion was based on his own active involvement in the activities for the Buryat cultural renaissance. Also, the scholar saw the religious movement of the Buryats in the 1900s as part of the global trend for secularization of the enlightenment.

Analysis of the parameters of the double clutch drive with reduced control energy consumption

The global trend of improving vehicle and traction transmissions is associated with the use of robotic preselector gearboxes, an important component of which is the friction clutch. The review of existing designs and analysis of clutch development concepts allows determining the directions of their improvement, in particular, the improvement of dry double clutches, which is the subject of research in this paper. A significant disadvantage of existing dual-clutch designs is the use of additional special (mostly hydraulic or combined) systems for on-off friction pairs, so the structural cost and energy costs for control are increased, and the design, maintenance, and repair are complicated. The proposed design of the drive to control the original dry dual-clutch involves a lever mechanism with the use of rotary stops, which are made in the form of mobile carriages with rollers, this provides switching clutches in a short time and actually without interruption of power flow, so the acceleration dynamics of vehicles will be improved, the clutch design will be simplified and energy consumption for its control during the start and gear shifting will be reduced. The mathematical model of the proposed clutch drive on the basis of which the control mechanism operation is simulated and influence of its design parameters on operational indicators of the clutch drive, in particular, on kinematic characteristics of the drive, ranges of kinematic and power gear ratios, the power interaction of the mechanism links, the power of the actuator when each clutch is turning on. It is established that the switching of clutches requires less energy, the movement of the mechanism elements is different, and the compression force of the friction pairs when starting the first and second clutches is different. The simulation results confirm that the proposed original lever design of the clutch control mechanism is effective. The obtained results allow us to reasonably determine the parameters of a clutch, but the choice of optimal-rational parameters of its control mechanism requires further research, for which appropriate methods, search algorithms, and their software implementation have been developed.

Onset and Decline Rates of Marine Heatwaves: Global Trends, Seasonal Forecasts and Marine Management

Changing ocean conditions due to anthropogenic climate change, particularly the increasing severity and frequency of extreme events, are a growing concern for a range of marine sectors. Here we explore the global trends in marine heatwaves (MHWs), specifically onset and decline rates, two metrics which describe how quickly a MHW will emerge or disappear from a location. These rates determine the reaction window—the start of a MHW event to peak MHW temperatures—and the coping window—time from peak temperatures to the end of an event—two important time periods relevant to a marine decision-maker. We show that MHW onset and decline rates are fastest in dynamic ocean regions and that overall, the global trend in onset rate is greater than the global trend in decline rate. We map ocean regions where these rates are changing together with forecast skill from a seasonal dynamical model (ACCESS-S). This analysis highlights areas where the length of the preparation window for impending MHWs is increased by using forecasts, and areas where marine decision-makers should be prepared for rapid responses based on realtime observations as MHWs evolve. In regions such as south Africa and Kerguelen, northwest Atlantic, northwest Pacific, southwest South Atlantic and off Australian east coast where rapid median onset and decline rates are observed, there is also a positive trend in onset and decline rates i.e., MHWs are developing and declining more rapidly. This will be a concern for many decision-makers operating in these regions.

GIS Analysis of Solar PV Locations and Disaster Risk Areas in Japan

Following the global trend of climate change mitigation, Japan has been rapidly increasing its share of renewable energy, in particular, its share of solar energy. However, Japan has limited flat land area that is suitable for solar photovoltaic (PV) power generation and a high risk of natural disasters. There is a possibility that some of its newly built solar power plants are located in areas where landslides and floods are likely to occur. Therefore, it is important to study the locations for solar PV from the perspective of disaster risk management. Previous studies have reported a number of incidents where solar PV installations were damaged as a result of natural disasters. One study utilized geographical analysis technology to reveal the overlapping of solar PV powerplant locations and disaster-prone areas in Fukuoka prefecture in Japan. However, to our best knowledge, no previous research about the solar PV locations' hazard risks has been done on a national scale. This paper investigates the risks stemming from landslides and floods for the existing solar PV power plants in Japan. We compare the geographical data of disaster risks in Japan with the location data of solar PV power plants to investigate the number of solar PV power plants located in disaster risk areas. Our results show that the shares of medium and large-scale solar PV power plants located in areas where landslides and floods are likely to occur are about 8.5 and 9.1% respectively.

Such systems perform the tasks of collecting, transmitting and processing data coming from the production, distribution, exchange and consumption of products. A brief look at digital technologies used in modern industry.

infrastructure of life

The infrastructure of the city accompanies a person at all stages of their biography, including death as an integral attribute of life. This section includes three articles, the authors of which appear in our journal for the first time. The articles discuss strong trends that usually escape the attention of architectural theorists. There is a return of communal and other forms of housing where people unrelated to each other live under the same roof. Is it a global trend or a forced measure against economic hardships? A rethink of the rental house, a rapid shift in the balance from home ownership to rental housing – how will this affect the architecture of cities? In the general trend of changing attitudes to death and the process of dying, the subject of hospice architecture until recently was taboo, but now strongly attracts architects’ attention. The articles of our new authors are more of a question-posing and problematic nature, which is exactly in the style of our journal.
