This research is devoted to the construction and the identification of a prior stochastic model for an uncertain Rigid Body (RB) of a multibody dynamical system (MDS). The methods developed in the context of the multibody dynamics analysis are commonly used in many application fields (Automotive, railway vehicles, launch vehicle,) for which the required accuracy makes the modelling and the quan...

A filament flapping in the bow wake of a rigid body is considered in order to study the hydrodynamic interaction between flexible and rigid bodies in tandem arrangement. Both numerical and experimental methods are adopted to analyze the motion of the filament, and the drag force on both bodies is computed. It is shown that the results largely depend on the gap between the two objects and the Re...

A four-year-old male Persian cat was referred with three weeks history of progressive lameness due to a rigid osseous mass with 3.50×2.50×2.00 cm in dimensions in his left arm. In the histopathological evaluation of bone biopsy, two distinct populations of cells including multinucleated giant cells and oval cells which embedded in a fibro-osseous stroma and surrounded by lamellar bone trabecula...

A old previously healthy woman presented to our outpatient clinic with a chief complaint of a huge mass in the left buttock that had gradually increased in size during the previous 7 years. The mass was painless, but it caused great difficulty in sitting and walking. She did not complain about dyspareunia or any problem with defecation. Physical examination revealed a 10-cm cystic mass in the l...

We present the case of an 84-year-old man with nonmassive hemoptysis and an obstructing endobronchial mass who was referred for rigid bronchoscopy and biopsy of the lesion. We illustrate how the pulsatile movement of his endobronchial lesion could be differentiated by convex probe endobronchial ultrasound bronchoscopy to be a vascular lesion rather than an endobronchial mass or tumor. Although ...

The objective of this study was to compare the lateral apparent mass of the seated human body measured in response to lateral and roll motions. The lateral apparent mass was measured at the seat surface using a rigid flat seat with no backrest. The axis of rotation of the roll motions was also at the seat surface. Tests were conducted using pseudo-random motions band-limited at 0.2 and 2 Hz rep...

We study the performance of optimal mass transport-based methods applied to point-set matching problems. The present study, which is based on the L2 mass transport cost, states that perfect matches always occur when the product of the point-set cardinality and the norm of the curl of the non-rigid deformation field does not exceed some constant. This analytic result is justified by a numerical ...

Large landslides exhibit surprisingly long runout distances compared to a rigid body sliding from the same slope, and the mechanism of this phenomena has been studied for decades. This paper shows that the observed long runouts can be explained quite simply via a granular pile flowing downhill, while collapsing and spreading, without the need for frictional weakening that has traditionally been...

107106-6464 IJET-IJENS © December 2010 IJENS I J E N S Abstract— Capacitive cantilever-mass micro-machined accelerometers have attracted much interest for properties such as a simple structure and potentially high sensitivity. This paper presents the simulation of a low-g capacitive cantilever-mass micro-machined accelerometer model to gain the desirable magnitude of displacement and capacitanc...

Flexibility is a concept associated with variable needs of human beings.Today transformable structures are used to meet human changeable demands with different purposes and functions such as facades, roofs, sunshades, etc.A Flexible structure must be able to change physically and adapt to predetermined conditions.To provide flexibility and adaptability,transformable systems are required to poss...
