The fully connected N-dimensional skeleton: probing the evolution of the cosmic web [PDF]

, 2008
A method to compute the full hierarchy of the critical subsets of a density field is presented. It is based on a watershed technique and uses a probability propagation scheme to improve the quality of the segmentation by circumventing the discreteness of

The prediction of equivalent granular steady state line of loose sand with fines [PDF]

, 2008
Void ratio has been used as a state variable for predicting the liquefaction behaviour of soils under the Critical State, sometimes also referred to as the Steady State, framework. Recent publications show that void ratio may not be a good parameter for

Critical undrained shear strength of sand-silt mixtures under monotonic loading

Earth Sciences Research Journal, 2014
This study uses experimental triaxial tests with monotonic loading to develop empirical relationships to estimate undrained critical shear strength. The effect of the fines content on undrained shear strength is analyzed for different density states. The

Geodesic network method for flows between two rough surfaces in contact [PDF]

, 2006
A discrete network method based on previous asymptotic analysis for computing fluid flows between confined rough surfaces is proposed. This random heterogeneous geodesic network method could be either applied to surfaces described by a continuous random ...

Designing Engaging Learning Experiences in Programming [PDF]

, 2018
In this paper we describe work to investigate the creation of engaging programming learning experiences. Background research informed the design of four fieldwork studies to explore how programming tasks could be framed to motivate learners.

Active Learning of Points-To Specifications

, 2018
When analyzing programs, large libraries pose significant challenges to static points-to analysis. A popular solution is to have a human analyst provide points-to specifications that summarize relevant behaviors of library code, which can substantially ...

Fractional-order plasticity model for sand-silt mixtures

Yantu gongcheng xuebao
The sand-silt mixtures, as common heterogeneous soils, are ubiquitous in nature and geotechnical engineering, and their particle contact state and mechanical properties are significantly affected by the factors such as density, stress level and fines ...

The Small World of Osteocytes: Connectomics of the Lacuno-Canalicular Network in Bone

, 2017
Osteocytes and their cell processes reside in a large, interconnected network of voids pervading the mineralized bone matrix of most vertebrates. This osteocyte lacuno-canalicular network (OLCN) is believed to play important roles in mechanosensing ...

Spatial development of transport structures in apple (Malus x domestica Borkh.) fruit [PDF]

, 2015
The void network and vascular system are important pathways for the transport of gases, water and solutes in apple fruit (Malus x domestica Borkh). Here we used X-ray micro-tomography at various spatial resolutions to investigate the growth of these ...
