Abstract The mechanical degradation of concrete structures is a phenomenon dependent on the material heterogeneity observed at mesoscale. As localized phenomenon, structural members and may be simulated using concurrent multiscale analysis technique. Thus, only most critical regions are modeled in mesoscale, reducing computational cost compared to simulation entire structure this scale. This wo...

The dimensions of microbumps in three-dimensional integration reach microscopic scales and thus necessitate a study of the multiscale microstructures in microbumps. Here, we present simulated mesoscale and atomic-scale microstructures of microbumps using phase field and phase field crystal models. Coupled microstructure, mechanical stress, and electromigration modeling was performed to highligh...

Oceanic mesoscale eddies with typical sizes of 30-200 km contain more than half of the kinetic energy of the ocean. With an average lifespan of several months, they are major contributors to the transport of heat, nutrients, plankton, dissolved oxygen and carbon in the ocean. Mesoscale eddies have been observed and studied over the past 50 years, nonetheless our understanding of the details of ...

An approach to an interoperable object-oriented GIS-framework for atmospheric modeling (AtmoGIS), which can be used to implement integrated information systems, is presented. The consideration of user-workflows leads to the specification of the projected system. Using an objectoriented approach, the system is based on a spatio-temporal database management system, a mesoscale model and an enviro...

cumulus convection, as a meso-scale phenomenon, results in the release of latent heat and vertical drift of energy that by part could affect the large scale field of energy, humidity, and momentum of the atmosphere. since the current numerical models are unable to resolve the singular cumulus convective clouds that are important from a meteorological point of view, it is used to apply some sort...

Our long-term technical goal is to produce a tested tangent linear and adjoint model for ROMS/TOMS (Regional Ocean Modeling System/Terrain-Following Ocean Modeling System) that is suitable for general use by ROMS/TOMS modelers. This is complementary to the Kalman Filter, ESSE, and Green’s Functions techniques being developed in other contexts. Our long-term scientific goal is to model and predi...

The aim of this study is to investigate the problems caused by discharge of polluted air from tunnels into the environment with a specific focus on residential areas. In city tunnels, portal or stacks, pollutant management is a big challenge. Nowadays, air quality management, particularly in urban tunnels, is considered as a part of the ventilation system design. The goal is to see the environm...
