Two Elementary Problems of Shell Deformation in Plasticity

Ioannis Doltsinis (Germany)

The two problems of plastic deformation of membrane shells dealt with are, the expansion of a spherical shell by internal pressure, and the shaping of a dome out of a circular disk. The first problem is easily accessible to an analytical solution which overcomes the pressure maximum and establishes the relationship between the expanding sphere radius and the pertaining pressure in dependence of the hardening of the material. This case may be considered in some sense introductory to the second problem, where a flat circular disk, clamped along the periphery, is blown by pressure such that a dome is formed [...]

Numerical Simulation of Droplet Combustion using Volume-of-Fluid Method

Tadashi Watanabe (Japan)

The droplet combustion is simulated numerically. The Navier-Stokes equations and the energy conservation equations together with the combustion model equations are solved in the computational fluid dynamics framework using the volume-of-fluid method. The characteristics of temperature increase due to combustion are simulated well, and the effect of ambient flow is made clear. It is shown that the droplet shape is varying and the high temperature region spreads widely in the ambient flow. The internal vortex flow is found to be driven by the surface tension force [...]

Simulation of wave run-up by means of the exact solution
of the wet/dry Riemann problem


Marco Tamburrino, Giovanni Cannata (Italy)

An innovative method for the simulation of the hydrodynamics in the swash zone, related to the wave run-up phenomenon, is presented. This method applies the exact solution of the Riemann problem over a dry bed to correctly evaluate the celerity of water waves propagating over the shore, and so to precisely track the coastline location. The simulations of velocity and wave fields outside the surf zone, inside the surf zone and in the swash zone, are carried out by means of a numerical model which solves 3D motion equations expressed in integral form, with a vertical coordinate that varies in time in order to follow the free surface evolution [...]

Robust Denoising Method Based on Tensor Models
Decomposition for Hyperspectral Imagery


Salah Bourennane, Caroline Fossati (France)

In the hyperspectral images (HSI) acquired by the new-generation hyperspectral sensors the signal dependent noise is an important limitation to the detection or classification. Therefore, noise reduction is an important preprocessing step to analyze the information in the hyperspectral image (HSI). A signal dependent noise cannot be reduced by conventional linear filtering [...]

On the Collapse Behavior of a Wood Arch made with Modular Hollow Blocks

Dora Foti, Michela Lerna, Maria Francesca Sabbà, Vitantonio Vacca (Italy)

In the field of construction, wood products are known to have environmental benefits if compared with materials like steel and concrete, especially regarding the reduction of carbon emissions of the production line. Today, the wood-architecture is maintained and renewed by the marketing of components or pre-manufactured wooden frame elements. This research consists in the numerical study of a wooden arch behavior realized with hollow blocks. Initially, experimental tests have been performed on a full-scale arch model. The results of the load tests have been compared with three different FEM-analyses [...]

Case Study on Geocoding Based Scheduling Optimization In
Supply Chain Operations Management


Steffen S. Rasmussen, Malleswara Talla, Raul Valverde (Denmark, Canada)

Traditional approach of ad-hoc geocoding for required addresses is quite time consuming and inefficient. In this paper, we propose and examine that the company-wide operations and addresses be geo-coded and stored in a database. As a case study, a geographical database is created for a company with primary focus to optimize operations management. This is done by storing the address information, the road network and a matrix containing time and distances to every address in the database. This approach prevents a lot of potential errors with ad hoc geocoding because every address is looked up in the database. The same goes for the time and distance matrix. Because the time and distances are stored for the distance between every address, no computations are needed at runtime [...]

Omnidirectional source modeling for ray tracing in room
acoustics with specular reflection


Benoit Beckers (France)

The aim of this work is to show that the use of a ray tracing method based on stratified Monte Carlo with cells of equal area and equal aspect ratio gives the most convincing results in room acoustic simulation. It is compared with three other methods: the first one is very close but simply uses equal area cells, the second one is a Monte Carlo importance sampling and the last one is a standard Monte Carlo where the values of the spherical coordinates of the rays are generated randomly [...]
