NASA's latest anthropomorphic robot, Robonaut, has reached a milestone in its capability. This highly dexterous robot, designed to assist astronauts in space, is now performing complex tasks at the Johnson Space Center that could previously only be carried out by humans. With 43 degrees of freedom, Robonaut is the first humanoid built for space and incorporates technology advances in dexterous ...

Movements of the body and especially of the hand are extremely complex, and are driven by several processes of biomechanical and neuroplastic types, among others. Their study presents a great interest in Human-Computer Interaction (HCI), in sportive and musical education, as well as in medicine and reeducation. The aim of this research was to capture and analyze highly complex gestures performe...

The paper outlines the development of a telerobotic control system with a focus on maximising the versatility of both production equipment and human operators. This was achieved by integrating sensory feedback from end effectors into the human-machine control loop. For most robotic applications, the robot executes a series of point-to-point movements along a predefined path. When an application...

This paper focuses on the complex design process of planar compliant mechanisms with flexure hinges. In the following a systematic methodology of the transition from lever mechanisms generated intuitively by the developer or non-intuitively by topology optimization to applicable compliant mechanism is presented. An extended pseudo-rigid-body model (PRBM) is used for the analysis and the modific...

Background Our study retrospectively assesses the safety and efficacy of the FOLFOX (oxaliplatin, fluorouracil, and leucovorin) versus DOF (docetaxel, oxaliplatin, and fluorouracil) regimens in untreated locally advanced gastric cancer (AGC). Patients and methods A total of 108 patients underwent DOF (N=58) and FOLFOX (N=50) regimens. The end points were overall response rate (ORR), survival,...

We present several techniques for user-centric viewing of the virtual objects or datasets under haptic exploration and manipulation. Depending on the type of tasks performed by the user, our algorithms compute automatic placement of the user viewpoint to navigate through the scene, to display the near-optimal views, and to reposition the viewpoint for haptic visualization. This is accomplished ...

We propose an extrinsic, continuous-Galerkin (CG), extended finite element method (XFEM) that allows multiple Heaviside enrichments within a single in hierarchical manner. This approach enables complex, evolving XFEM surfaces 3D cannot be captured using existing CG-XFEM approaches. describe implementation of the for static elasticity with linearized strain modeling open cracks as salient step t...

Interference alignment (IA) is a technique recently shown to achieve the maximum degrees of freedom (DoF) of Kuser interference channel. In this paper, we focus on the precoder designs on manifolds for IA. By restricting the optimization only at the transmitters’ side, it will alleviate the overhead induced by alternation between the forward and reverse links significantly. Firstly a classical ...
