3-D catalytic regeneration and stress modeling of diesel particulate filters by ABAQUS FEM software
(2002)The design of reliable DPF systems has proved a complex and demanding task that is increasingly being assisted by modeling. 1-D but also 2-D (axisymmetric) modeling has already been applied in design optimization case ... -
3-D simulations of flows in the reconstituted lake Karla, Thessaly, Greece
(2010)We report on three-dimensional flow simulations carried out in order to describe the dominant water current patterns in the reconstituted lake Karla. The flow is considered to be generated mainly by wind shear while the ... -
3D protein-protein docking using shape complementarity and fast alignment
(2011)In this paper, a novel approach for fast protein-protein docking based on geometric complementarity is introduced. Complementarity matching is achieved using a rotation-invariant 3D shape descriptor, the Shape Impact ... -
A finite element model of the Ilizarov fixator system
(2011)Mechanical characteristics of orthopaedic fixators, such as stiffness and stability, directly influence the mechanobiological environment in which the bone is healed. A comprehensive understanding of the sensitivity of the ... -
Finite element modeling of porous solid propellants
(2005)The effect of porosity on the constitutive response of a linearly viscoelastic solid that obeys a constitutive law of the standard differential form is investigated under small strain deformation conditions. It is demonstrated ... -
An intelligent tool for anatomical object segmentation using deformable surfaces
(2012)Image segmentation is a very active area of research in machine vision. In this work, an innovative methodology is presented that allows the segmentation of objects in three-dimensional images with initial user intervention. ... -
Interactive installations and the conception of space - An introduction
(2006)Today we are living in the midst of an emerging new iconographic paradigm, that of the digital image. On one hand all information media and cultural objects can be transferred and encoded in digital form while on the other ... -
Non-linear 3D simulation of the construction and impounding of a CFRD
(2008)A general methodology for the non-linear 3D numerical simulation of the phased construction and subsequent reservoir impoundment of a concrete faced rockfill dam built in a narrow canyon is presented. The common characteristic ... -
Parametric analysis of axially loaded RHS gap K-joints by means of 2-D and 3-D F.E. models
(2003)In the present paper the behaviour of steel structural RHS gap K-joints under static loading is studied by applying the Finite Element Method. The analysis is performed by the development of both 2-D and 3-D models of gap ... -
Photon dose kernels dataset for nuclear medicine dosimetry, using the GATE Monte Carlo toolkit
(2012)Photon dose point kernels (DPKs) were generated using the GATE toolkit for different media and for radionuclides of interest in nuclear medicine. In the present work the primary photon contribution of different isotopes ... -
Power, performance and area prediction of 3D ICs during early stage design exploration in 45nm
(2011)In this work, the impact of across-chip temperature and power supply voltage variations, on performance predictions in 3D ICs, is investigated. To make this possible, a novel design flow is proposed to perform design ... -
Prediction of collapse of the osteonecrosis of the hip by determining location and size of the lesion: A 2 to 17 years study
(2010)Osteonecrosis of the femoral head is a disease responsible for a large number of arthroplasties in young and active patients in the western world. Prediction of outcome of the disease remains a difficult task. The purpose ... -
Response of pile groups in clays under lateral loading based on 3-D numerical experiments
(2010)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. Although simplified numerical methods are reliable for evaluating the response of a single pile ... -
Semantic based search engine for 3D shapes: Design and early prototype implementation
(2005)Searching for 3D resources is gradually becoming one of those intriguing research topics that have the potential to shape how users will access and interact with the internet in the years to come. Search engines like Google ... -
