The complete 3D nonlinear dynamic problem of extensible, flexible risers conveying fluid is considered. For describing the dynamics of the system, the Newtonian derivation procedure is followed. The velocity field inside the pipe formulated using hydrostatic and Bernoulli equations. The hydrodynamic effects of external fluids are taken into consideration through the nonlinear drag forces in var...
The Virtual Environment Vehicle Interface (VEVI) is a software environment developed for the control and visualization of remotely located robotic vehicles. The design and implementation of this interface were driven by experience with several field missions which have defined key areas to be addressed. This paper describes three of these concepts and demonstrates the approach with examples fro...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
the purpose of this study is to investigate and explore the causes of identity crisis as one of the debilitating consequences of colonial project after the withdrawal of colonial power. in order to do justice to the full-length severity of displacement that was the fruit of indentureship, v. s. naipauls west indian epic, a house for mr biswas, has been scrutinized with the main focus being the ...
A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

The dynamic analysis of railway vehicles involves the construction of three independent models: the vehicle model; the track model; and the wheel-rail contact model. In this work, a multibody formulation with Cartesian coordinates is used to describe the kinematic structure of the rigid bodies and joints that constitute the vehicle model. A methodology is also proposed in order to create detail...
This paper presents a Gaussian radial basis function neural network based on sliding mode control for trajectory tracking and vibration control of a flexible joint manipulator. To study the effectiveness of the controllers, designed controller is developed for tip angular position control of a flexible joint manipulator. The adaptation laws of designed controller are obtained based on sliding m...
The paper describes the architecture and implementation of the dynamic analysis tools that are part of the DOBERTSEE environment. DOBERTSEE is a low-cost, flexible software engineering environment which enables different development processes and methods to be supported by integrating different tools. An XML-based language is used as a basis for integration. The current version of the environme...
