Text en actes de congrés
Accés obertIn this work a numerical model for analysis of reinforced concrete structures under seismic load is presented. The model uses the combined finite-discrete element method; thus taking into account the discontinuous nature ... -
A combined implicit-explicit algorithm in time for non-linear finite element analysis
(2006-01)
Article
Accés obertAn algorithm combining the numerical execution in time of implicit and explicit methods of solution is presented in this paper. The algorithm swaps between both methods as required for the analysis. The whole mesh is solved ... -
A combined inventory routing and game theory approach for a real-world distribution problem
(2009-07-06)
Text en actes de congrés
Accés obertIn this paper, we develop a solution approach combining inventory routing and game theory and discuss it application to solve a real-world distribution and logistics problem. The problem consists of developing a distribution ... -
A combined kernel-PCA with clustering analysis for bridge damage detection under changing environmental conditions
(2020)
Text en actes de congrés
Accés restringit per política de l'editorialDamage caused in bridges can be hidden by the service conditions mainly due to environment effects as temperature and traffic loading. The literature review indicates that the majority of investigations are limited since ... -
A combined methodology for transportation planning assessment: application to a case study
(2001-05)
Article
Accés obertTraffic assignment models based on the user-equilibrium approach are one of the most widely used tools in transportation planning analysis. Resulting offer a static average view of the expected use of the road infrastructure ... -
A combined methodology of adaptive neuro-fuzzy inference system and genetic algorithm for short-term energy forecasting
(2014-02)
Article
Accés obertThis document presents an energy forecast methodology using Adaptive Neuro-Fuzzy Inference System (ANFIS) and Genetic Algorithms (GA). The GA has been used for the selection of the training inputs of the ANFIS in order to ... -
A combined polling and ISMA-DS/CDMA protocol to provide QoS in packet mobile communications systems
(Institute of Electrical and Electronics Engineers (IEEE), 2000)
Text en actes de congrés
Accés obertThis paper presents a new mechanism that combines the flexibility of an access protocol such as ISMA-DS/CDMA with the ability of a polling mechanism to provide a specific bound for the access delay. This protocol is proposed ... -
A combined reduced order-full order methodology for the solution of 3D magneto-mechanical problems with application to magnetic resonance imaging scanners
(2020-01-01)
Article
Accés obertThe design of a new magnetic resonance imaging (MRI) scanner requires multiple numerical simulations of the same magneto-mechanical problem for varying model parameters, such as frequency and electric conductivity, in order ... -
A combined rh-adaptive scheme based on domain subdivision. Formulation and linear examples
(Wiley and Sons, 2001-09)
Article
Accés obertAn adaptive scheme is proposed in which the domain is split into two subdomains. One subdomain consists of regions where the discretization is refined with an h-adaptive approach, whereas in the other subdomain node ... -
A combined scheduling reactive scheduling strategy to minimize the effect of process operations uncertainty in batch plants
(Pergamon Press, 1996)
Article
Accés restringit per política de l'editorialThis paper deals with production scheduling of multipurpose batch chemical plants under uncertainty. The uncertainty associated with process operations causes that production can not be carried out exactly as scheduled. ... -
A combined spectral-parabolic equation approach for propagation prediction in tunnels
(2010)
Text en actes de congrés
Accés obertSeveral techniques can be used to study electromagnetic propagation in tunnels. A combination of two of such techniques is presented in this paper to model propagation inside a rectangular tunnel. They are combined in ... -
A combined study of expansive and tensile strength evolution of mortars under sulfate attack: implications on durability assessment
(2010-03-04)
Article
Accés obertEn este trabajo se presenta un estudio combinado de la evolución de la expansión y resistencia a tracción de cementos Portland con contenidos variables de C3A. Esta aproximación ha demostrado ser útil en el diagnóstico ... -
A combined XFEM phase-field computational model for crack growth without remeshing
(Springer, 2020-10-07)
Article
Accés obertThis paper presents an adaptive strategy for phase-field simulations with transition to fracture. The phase-field equations are solved only in small subdomains around crack tips to determine propagation, while an XFEM ... -
