Abstract It is of great theoretical significance and engineering application to investigate the influence detonation interval on dynamic response underground fortification under blasting loading. First, a numerical simulation blast loading carried out based continuum-discontinuum element method. Then, displacement characteristic analyzed. Finally, fracture The results indicate that increasing t...

Elevated water tanks supported by the reinforced concrete (RC) Staging are classified as inverted pendulum structures. These are considered as structures of high post-earthquake importance and should remain functional after the seismic events. National codes of various countries recommend Force-Based Design (FBD) procedure for water tank staging, which does not ensure nonlinear performance leve...

UNLABELLED Many modern low-energy ventilation schemes, such as displacement or natural ventilation, take advantage of temperature stratification in a space, extracting the warmest air from the top of the room. The adoption of these energy-efficient ventilation systems still requires the provision of acceptable indoor air quality. In this work we study the steady state transport of particulate c...

Natural enemies may contribute to the morphological divergence of sympatric species, yet their role has received little attention to date. We tested for character shifts in defensive armor of sympatric threespine sticklebacks (Gasterosteus aculeatus complex) previously shown to exhibit ecological character displacement in traits related to resource use. We scored five defensive armor traits in ...

Vertical movement and distribution of Cryptolestes ferrugineus (Coleoptera: Laemophloeidae) adults in stored wheat and corn were studied in small (0.1 x 0.1 x 1 m) and large (0.6 m diameter and 1.12 m high) columns. The adults were introduced at the top, middle, and bottom of the small columns with a uniform moisture content (wheat: 14.5 +/- 0.1%, corn 13.5 +/- 0.1%, 15.5 +/- 0.1%, and 17.5 +/-...

Within the field of criminology, one of the main research interests is the analysis of the displacement of crime. Typical questions that are important in understanding the displacement of crime are: When do hot spots of high crime rates emerge? Where do they emerge? And, perhaps most importantly, how can they be prevented? In this paper, an agent-based simulation model of crime displacement is ...

This study presents the optimal drift design method to control the elastic and inelastic performance of steel moment frames. This is formulated as a problem that minimizes the lateral displacement at the top of a building satisfying the constraints on the total structural weight and the column-to-beam strength ratios at the joints. This uses the resizing method based on the linear static analys...

We investigate the problem of estimating magma chamber geometry using InSAR observations of Sierra Negra volcano, Galápagos. Ascending and descending interferograms are combined to determine vertical and one horizontal component of displacement. The ratio of maximum horizontal to vertical displacement suggests a sill-like source. Spherical or stock-like bodies are inconsistent with the data. We...

Memory for targets moving in depth and for stationary targets was examined in five experiments. Memory for targets moving in depth was displaced behind the target with slower target velocities (longer ISIs and retention intervals) and beyond the target with faster target velocities (shorter ISIs and retention intervals), and the overall magnitude of forward displacement for motion in depth was ...

We study experimentally the distribution of local stresses in a granular material confined inside a vertical cylinder. We use an image correlation technique to measure the displacement field of the container induced by the forces exerted by the grains on the inner wall. We describe an optimization procedure based on the linear theory of elastic shells to deduce the distribution of these forces ...
