A spatial six degree freedom mathematical model of a three wheeled vehicle (TWV) used in Asian countries has been developed using multi body system approach. The model includes suspension and tyre compliance. The model consists of a single sprung mass (vehicle body) connected to three unsprung masses (three wheels) at each corner. The suspensions and tires are modeled as springs and linear damp...

Starting from general considerations about the different concepts which exist for the definition of the quark mass near the pair production threshold, we introduce the definition of a mass with a dynamic degree of freedom that extends the previously given concept of the static PS mass. Talk given by Stefan Groote at the Laboratory of Nuclear Studies, Cornell University, Ithaca, NY, August 23rd,...

in this study, mass, stiffness and damping matrices of the nosrat jacket; located in persian gulf; equipped with semi active tuned mass damper (satmd) system have been derived after modeling the structure in sacs software. owing to huge number of the degrees of freedom in the model, computation of on-line control of satmd was time consuming. for this purpose, the size of the model was reduced i...

LIBRARY TRENDS, Vol. 63, No. 1, 2014 (“New Perspectives on Intellectual Freedom,” edited by Mark McCallon), pp. 75–108. © 2014 The Board of Trustees, University of Illinois Abstract Traditionally the concept of intellectual freedom has developed out of the perspective of users’ rights to access library materials. The American Library Association (ALA) codified this with the Library Bill of Righ...

Models of the vertical apparent mass of the human body are mostly restricted to a sitting posture unsupported by a backrest and ignore the variations in apparent mass associated with changes in posture and changes in the magnitude of vibration. Using findings from experimental research, this study fitted a single degree-of-freedom lumped parameter model to the measured vertical apparent mass of...

We consider a two-form antisymmetric tensor field φ minimally coupled to a nonabelian vector field with a field strength F . Canonical analysis suggests that a pseudoscalar mass term μ 2 2 Tr(φ∧φ) for the tensor field eliminates degrees of freedom associated with this field. Explicit one loop calculations show that an additional coupling mTr(φ ∧ F ) (which can be eliminated classically by a ten...

In this research, optimal design and assessment of multiple tuned mass dampers (MTMDs) capability in mitigating the damage of nonlinear steel structures subjected to earthquake excitation has been studied. Optimal parameters of TMDs on nonlinear multi-degree-of-freedom (MDOF) structures have been determined based on minimizing the maximum relative displacement (drift) of structure where for sol...
