Heat recovery from an enhanced geothermal system (EGS) is a complex process involving heat transport in both fracture networks and rock formations. A comprehensive understanding of the ability to model underlying mechanisms important for success EGS commercialization but remains challenging practice due generally insufficient characterization reservoirs. In present study, we analyze extensively...

Water injection and Enhanced Geothermal System (EGS) technologies have been used to exploit heat resources from geothermal reservoirs. Detecting spatial temporal changes in reservoir physical properties is important for monitoring condition due water EGS. Here, we determine high-resolution models of the three-dimensional P wave velocity attenuation (Vp Qp) structures between years 2005 2011 nor...

Human activities, such as fluid injection as part of the stimulation of an enhanced geothermal system (EGS) for heat and power production, can cause damaging earthquake ground motions. A difficulty in quickly settling or rejecting insurance claims to the policy of the operator of the EGS is the lack of ground truth on the observed shaking at sites of reported damage. To overcome this problem a ...

Gamification is the concept of applying game elements in non-game context platforms to motivate people to participate in planned activities to achieve goals. Gamification has been applied to academic fields including software engineering (SE) in recent years. Many gamification implementations in SE have been ad hoc and lacked standardized guidelines. This paper introduces a new concept of build...

Research into the sustainability of geothermal energy previously focused on the management and use of the resource (Rybach and Mongillo, 2006) and the environmental impacts during geothermal energy production (Bloomfield et al., 2003; Reed and Renner, 1995). Within these constraints, studies have shown that there will be less impact on air emissions (including greenhouse gases), water consumpti...

A Markov equivalence class contains all the Directed Acyclic Graphs (DAGs) encoding the same conditional independencies, and is represented by a Completed Partially Directed DAG (CPDAG), also named Essential Graph (EG). We approach the problem of model selection among noncausal sparse Gaussian DAGs by directly scoring EGs, using an objective Bayes method. Specifically, we construct objective pr...

Single-layered graphene has unique electronic, chemical, and electromechanical properties. Recently, graphite exfoliation in N-methylpyrrolidone and molten salt has been demonstrated to generate monolayer exfoliated graphene sheets (EGS). However, these solvents are either high-priced or require special care and have high boiling points and viscosities, making it difficult to deposit the disper...

At the request of the U.S. Department of Energy, the JASON group that provides independent technical advice to the U.S. Government studied Enhanced Geothermal Systems (EGS) with a focus on i) assessment of technologies and approaches for subsurface imaging and characterization; and ii) assessment of approaches toward creating sites for EGS, including science and engineering to enhance permeabil...

Enhancement of the effectiveness and efficiency of e-government services (EGS) is critical to better meeting the increasing public demands for services. One of the better solutions to meet such demands is improving the government’s EGS capability (EGSC). However, few studies discuss the issues. The purpose of this study was to employ capability management perspectives to develop theoretical lin...

The special nature of groceries, especially perishables, challenges the possibilities of digital channels i.e. computers and networks to improve customer service. We report the findings of theme interviews on the potential of electronic commerce (EC) of groceries with 33 experts of grocery industry and EC, most of them senior executives, in 23 organisations in Finland during the Autumn of 1997....
