Fractures and fracture networks are the principal pathways for migration of water and contaminants in groundwater systems, fluids in enhanced geothermal systems (EGS), oil and gas in petroleum reservoirs, carbon dioxide leakage from geological carbon sequestration, and radioactive and toxic industrial wastes from underground storage repositories. When dealing with EGS fracture networks, there a...

Peirce believed that his pragmaticism can be conclusively proven. Beginning in 1903, he drafted several attempts, ending by 1908 with a semeiotic proof. Around 1905, he exposes the proof using the theory of Existential Graphs (EGs). This paper modernises the semantics Peirce proposed for EGs in terms of game-theoretic semantics (GTS). Peirce’s 1905 proof is then reconstructed in three parts, by...

background: as bremsstrahlung photon beam fluence is important parameter to be known in a photonuclear reaction experiment as the number of produced particle is strongly depends on photon fluence. materials and methods: photon production yield from different thickness of aluminum target has been estimated using artificial neural network (ann) model. target thickness and incoming electron energy...

We show that the maximum number of edges bounding m faces in an arrangement of n line segments in the plane is O(m2/3n2/3+nα(n)+n logm). This improves a previous upper bound of Edelsbrunner et al. [EGS] and almost matches the best known lower bound which is Ω(m2/3n2/3 + nα(n)). In addition, we show that the number of edges bounding any m faces in an arrangement of n line segments with a total o...

The enhanced geothermal system (EGS) is the key to improving heat production efficiency of hot dry rock (HDR). Due existence EGS, reservoir produces significant heterogeneity, so optimal design well location and injection rate has an important influence on recovery effect EGS. To solve this problem, a calculation model for output EGS under multifield coupling established in paper, different sca...

Vegetation phenology regulates many ecosystem processes and is an indicator of the biological responses to climate change. It is important to model the timing of leaf senescence accurately, since the canopy duration and carbon assimilation are strongly determined by the timings of leaf senescence. However, the existing phenology models are unlikely to accurately predict the end of the growing s...

This study looks at the role that social factors play in a consumer’s decision to purchase goods or services online. Of particular consideration to this research is the Australian electronic grocery shopping (EGS) industry. Social factors have been found to play a part in technology adoption studies. This research looks at EGS as a technological innovation, and attempts to assess the priorities...

A century ago, Charles S. Peirce proposed a logical approach to modalities that came close to possible-worlds semantics. This paper investigates his views on modalities through his diagrammatic logic of Existential Graphs (EGs). The contribution of the gamma part of EGs to the study of modalities is examined. Some ramifications of Peirce’s remarks are presented and placed into a contemporary pe...

Monte Carlo Event Generators (EGs) have developed into essential tools in High Energy Physics. Without them it is questionable if it at all would be possible to embark on large scale experiments such as the LHC. Although the current EGs work satisfactorily, the next generation of experiments will substantially increase the demands both on the physics models implemented in the EGs and on the und...
