ABSTRACT - Merapi Mount (2978 msl) is the higher active volcanoes in Indonesia, which located between Sleman district, DI. Yogyakarta, and Magelang Boyolali Klaten Central Java. The eruption center of controlled by weak or unstable zone. This zone can be known from several lithologies rock, lies below Mount's surfaces through density differences. One methods for determining subsurface geophysic...

The reconciliation of engineering designs that do not have survey information, involve accurate configuration the proposed constructions at their respective locations on-site requires first a topographic to obtain perimeter plan, which in turn, shows area, shape, and orientation site; spot heights plan showing existing ground levels thereby used decide on suitable gradients determine appropriat...

Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess personal and environmental sound pressure level project sound-Isosonic map Razavi Khorasan Paste manufacture using Surfer V.14 at V.5.0. This cross-sectional, descriptive analytical that was conducted 2018 factory contains Canister, production Brewing unit. Following ISO 96...

Grouting reinforcement is one of the most effective methods to enhance stability goaf, and its scheme selection, hole location, parameter determination directly affect success or failure goaf treatment. On basis discussion deformation mechanism evolution law longwall this article comprehensively analyzed grouting combined with filling theory, permeability fracturing theory studied physical chem...

In order to study the freezing front characteristics of alpine tunnels under condition wind flow field and relying on Osaka Mountain tunnel in Qinghai Province, physical model test an was built. By using Surfer software combined with laboratory data, radial longitudinal temperature variation trends were obtained, overall vector graph simulated; evolutionary laws a airflow conditions systematica...

Nutrients such as phosphate and soil particles are much more susceptible to loss with sediments in eroding run-off water, this due the erosion has a negative influence on agricultural output. To prevent it, various approaches have been taken, including idea that particle driven coagulation may speed up sedimentation minimize quantity of material lost. The specific purpose study was examine effi...

Abstract The presence of manifestation in the Gondang indicates a specific geological condition. Those manifestations are Banyu Kuning Hot Spring, Selo Gajah and Jari Mud Burst. purpose this study, which was carried out near Mount Pandan, to identify distribution magnetic fields anomalies, including patterns potential geothermal energy region based on its magnetism. It also aimed explain rock s...

Human activities contribute to the contamination of rivers by toxic elements, causing serious effects on health traditional communities in Amazon region. With aim verifying spatial distribution Hg and As concentrations a region affected gold mining Baú, Curuá, Curuaés River basin, municipality Altamira-PA, Brazilian Amazon, study was carried out using geostatistical maps. The quantification ele...

How can we augment a dynamic graph for improving the performance of neural networks? Graph augmentation has been widely utilized to boost learning GNN-based models. However, most existing approaches only enhance spatial structure within an input static by transforming graph, and do not consider dynamics caused time such as temporal locality, i.e., recent edges are more influential than earlier ...
