In general, joints are assumed without clearance in the dynamic analysis of multi-body echanical systems. When joint clearance is considered, the mechanism obtains two uncontrollable degrees of freedom and hence the dynamic response considerably changes. The joints’ clearances are the main sources of vibrations and noise due to the impact of the coupling parts in the joints. Therefore, the syst...

Multi-People Tracking in an open-world setting requires a special effort in precise detection. Moreover, temporal continuity in the detection phase gains more importance when scene cluttering introduces the challenging problems of occluded targets. For the purpose, we propose a deep network architecture that jointly extracts people body parts and associates them across short temporal spans. Our...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

Tracking human poses in video can be considered as the process of inferring the positions of the body joints. Among various obstacles to this task, one of the most challenging is to deal with ‘self-occlusion’, where one body part occludes another one. In order to tackle this problem, a model must represent the self-occlusion between different body parts which leads to complex inference problems...

Miracle mice When, in 1994, Dr Ellen Heber-Katz of the Wistar Institute in Philadelphia was monitoring marked mice in a group that she used as experimental animals in connection with her research on multiple sclerosis, she received a surprise. The marked mice could not be found! They had punch holes in the ears for identification, and at first it seemed as though a mistake had been made, for no...

Abstract We present force platform measurements and video tracking analysis of a kettlebell-trained international top athlete performing the kettlebell lifts long cycle snatch. The ground reaction measured with strongly varies during lift. Video reveals contributions kettlebells athlete’s body parts to force. agree forces estimated from usually within 30%. presented data allows estimates energy...

This paper proposes a method of simulating the movements of the human body by automatically extracting the characteristics of an object from a camera and sending them to mobile devices. In this method, a RGB color video from a camera was converted into hue, saturation, and intensity images for extracting the silhouettes of the human body using digital subtraction of the images. Using the corner...

In this paper, we present a new bottom-up one-stage method for whole-body pose estimation, which call “hierarchical point regression,” or HPRNet short. standard body the locations of ~17 major joints on human are estimated. Differently, in fine-grained keypoints (68 face, 21 each hand and 3 foot) estimated as well, creates scale variance problem that needs to be addressed. To handle among diffe...

Placoderms are considered as the first jawed vertebrates and constitute a paraphyletic group in the stem-gnathostome grade. The acanthothoracid placoderms are among the phylogenetically most basal and morphologically primitive gnathostomes, but their neurocranial anatomy is poorly understood. Here we present a near-complete three-dimensional skull of Romundina stellina, a small Early Devonian a...
