Developing software architectures for complex software applications is challenging, and requires good static and dynamic visualisation support. We describe the visual software architecture modelling visual language we have developed and its support in the SoftArch environment. Static software architecture views are developed using this language, and designs and implementations developed from th...

in this paper, the application of neural networks for simulation and optimization of the cogeneration systems has been presented. cgam problem, a benchmark in cogeneration systems, is chosen as a casestudy. thermodynamic model includes precise modeling of the whole plant. for simulation of the steadysate behavior, the static neural network is applied. then using dynamic neural network, plant is...

The database model CDM intended for modelling design objects is presented. All properties of design objects are modelled by functions. For modelling dynamic dependencies among objects we introduce the notion of dynamic function. The dynamic function comprises capabilities for the description of the object static structure and algorithmic dependencies among objects. Some constraints and practica...

This paper presents a complete derivation and implementation of the Arbitrary Lagrangian Eulerian (ALE) formulation for the simulation of nonlinear static and dynamic problems in solid mechanics. While most of the previous work done on ALE for dynamic applications was mainly based on operator split and explicit calculations, this work derives the quasi-static and dynamic ALE equations in its si...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

The focus of this paper is on the modelling primitives which are not only taking into account semantic models of traditional approaches for information system development, but also put a communication aspect into the foreground of system analysis. Integration of static, dynamic and non-traditional communication dependencies is considered as a most important feature of the suggested framework. I...

among the deformities of the spine in sagittal plane, kyphosis is one of the most important cases in the study of postural control from the mechanical standpoint because the smallest deviation of upper limb, that is almost 60 percent of total body weight in standing position, causes displacement of body center of mass to forward and finally will causes weaker balance performance in kyphotic ind...

This paper investigates the parametric study of the empty and foam-filled end-capped tubes under quasi static and dynamic loadings. The numerical crash analysis of the empty and foam-filled tubes was performed using the explicit finite element code ABAQUS- explicit. Satisfactory agreements were generally achieved between the numerical and experimental results. In order to determine the crash be...
