The collapse potential, mineralogy, microstructure, and particle morphology of a loess from the Loess Plateau, China, were characterized by double oedometer testing, X-ray diffraction, scanning electron microscopy with energy-dispersive spectroscopy, image analysis to elucidate origin its behavior. Results show that is highly collapsible maximum index 6.7% at vertical stress ∼200 kPa. deposit contains both nonclay (i.e., quartz, albite, muscovite, calcite) clay two chlorites) minerals....

In a ciphertext-policy attribute-based encryption (CP-ABE) system, decryption keys are defined over attributes shared by multiple users. Given key, it may not be always possible to trace the original key owner. As privilege could possessed users who own same set of attributes, malicious might tempted leak their privileges some third parties, for financial gain as an example, without risk being caught. This problem severely limits applications CP-ABE. Several traceable CP-ABE (T-CP-ABE)...

Loess, which primarily consists of wind-transported silt and clay particles, is widely distributed around the world, including central Asia, Europe, northwestern United States, Alaska, South America. The metastable structure natural loess has resulted in construction delays catastrophic failures. To explore potential applications soil improvement with green materials, this paper presents an experimental study applying fly ash–based geopolymers for stabilization. Two different precursors are...

With the emergence of Yahoo Pipes and several similar services, data mashup tools have started to gain interest business users. Making these simple accessible ton users with no or little programming experience has become a pressing issue. In this paper we introduce MARIO (Mashup Automation Runtime Orchestration Invocation), new tool that radically simplifies composition. We developed an intelligent automatic composition engine in together user interface using intuitive "wishful search"...

Aiming to solve the problems caused by construction and demolition waste depletion of natural aggregates, in present study, both coarse recycled aggregates fine are used produce new green concrete with a fly ash–based geopolymer. The mechanical study shows that reduction rates compressive strength, Young's modulus, Poisson's ratio geopolymeric aggregate (GRAC) specimens increase water/cement (w/c) ratio. modulus is much more vulnerable w/c than strength. These significant changes GRAC...

A blackbox traceable Attribute-Based Encryption (ABE) can identify a malicious user called traitor, which created decryption box with respect to an attribute set (respectively, access policy), out of all the users who share same policy). However, none existing ABE schemes also support revocation and large universe, that is, being able revoke compromised keys, take exponentially number attributes. In this paper, we formalize definitions security models, propose constructions both...

The inverse-distance weighting interpolation is widely used in 3D geological modeling and directly affects the accuracy of models. With development “smart” or “intelligent” geology, classical cannot meet accuracy, reliability, efficiency requirements large-scale models these fields. Although improved can basically it at same time. In response to limitations, adaptive method based on attribute spatial differentiation feature adaptation was proposed. This takes into account attributes improve...

Simulation of a geostratigraphic unit is vital importance for the study geoinformatics, as well geoengineering planning and design. A traditional method depends on guidance expert experience, which subjective limited, thereby making effective evaluation stratum simulation quite impossible. To solve this problem, proposes machine learning series simulation. On basis recurrent neural network, sequence model type thickness successively established. The performance improved in combination with...
