The electronic properties of deformed armchair carbon nanotubes are modeled using constraint free density functional tight binding molecular dynamics simulations. Independent from CNT diameter, deforming path can be divided into three regimes. In the first regime, the nanotube deforms with negligible force. In the second one, there is significantly more resistance to deforming with the force be...

What does it mean for a deforming object to be “moving”? How can we separate the overall motion (a finite-dimensional group action) from the more general deformation (a diffeomorphism)? In this paper we propose a definition of motion for a deforming object and introduce a notion of “shape average” as the entity that separates the motion from the deformation. Our definition allows us to derive n...

What does it mean for a deforming object to be “moving” (see Fig. 1)? How can we separate the overall motion (a finite-dimensional group action) from the more general deformation (a diffeomorphism)? In this paper we propose a definition of motion for a deforming object and introduce a notion of “shape average” as the entity that separates the motion from the deformation.

OBJECTIVES To analyse the factors predicting erosive-deforming arthropathy in patients with psoriatic arthritis (PsA). METHODS A prospective cohort study was undertaken with 71 patients diagnosed as having PsA (44 men and 27 women, mean age 47 (SD 12) years). At the recruitment period patients had disease without evidence of radiological damage. Patients were studied and followed up according...

this article examines the effect of philosophical mindset on the entrepreneurial tendencies of small and medium businesses’ managers. a correlational study was conducted by drawing on a descriptive design. the population included 361 managers of small and medium businesses in 9 provinces. the required information was gleaned through two questionnaires. finally, the obtained data was analyzed us...

It is not difficult to be charmed by an intelligent, glib talker. However, this could only be a few of the sociopathic tendencies of an individual. More correctly cited as a result of antisocial personality disorder, sociopaths are characterized by their utter disregard for the rights of others. They exude superficial charm that may easily attract others. However, within a short period of being...

In this paper, an implementation of visual and haptic feedback of deforming and cutting operations is discussed. In the implementation of the deforming operation, the surface shape is represented by a geometric model while the physical reaction is simulated using a spring model. The deformation of the spring model is reflected onto the geometric model by using the interpolation technique. In th...

In computer graphics, many automatic methods for simplifying polygonal meshes have been developed. These techniques work very well for static meshes; however, they do not handle the case of deforming objects. Simplifying any single pose of a deforming object may destroy detail required to represent the shape in a different pose. We present an automatic technique for simplifying deforming charac...
