This article analyzes low-carbon lifestyle and characteristics of five dimensions of Internet-based lifestyle on the basis of division of lifestyle into attitude, behavior, time, space, and matter. Internet-based lifestyle is a low-carbon lifestyle. But it can hardly sustain because of the unhealthy and incomplete configurations. An example from online network, the article initials a new era of constructing...
This paper investigates the effects of ankle joint stiffness on gait selection of dynamic bipedal walking with flat feet. We present a dynamic bipedal walking model with upper body, flat feet and compliant joints. The model can generate the three common gaits of dynamic bipedal walking. Simulation experiments are carried out to verify the analytical results and provide further results on gait comparison...
Multi-touch interaction is a more free interaction means, however, recent related applications limit in the 2D area, such as interaction desktop, shop window. For the applications in virtual exhibition, this paper proposes a 3D multi-touch recognition method. The different gestures firstly are defined for gesture recognition. Then a character recognition algorithm based on directions is presented...
This paper presents a seven-link dynamic walking model that is more close to human beings. We add hip actuation, upper body, flat feet and compliant ankle joints to the model. Walking sequence of the flat-foot walker has several sub-streams that form bipedal walking with dynamic series of phases, which is different with the motion of round-foot and point-foot models. We investigate the characteristics...
This paper formulates the mathematical model of a biped that is capable of dynamic walking gaits. The model consists of hip actuation, segmented legs, flat feet and torsional spring based passive ankle stiffness. Using numerical simulations on the proposed model, we find that from the view of stability, there is optimal foot-ankle ratio of the flat-foot bipeds. The results indicate that the human...
This paper presents the design of a novel powered ankle-foot prosthesis with compliant ankle and segmented foot. The powered compliant ankle is proposed to replace the able-bodied ankle which can provide sufficient power to propel the body upward and forward during bipedal walking. In order to make the walking gaits of the amputees more stable and natural, we introduce segmented foot with toe joint...
This paper presents a passive dynamic walking model with segmented feet. The model extends the Simplest Walking Model with the addition of flat feet and torsional springs based compliance on ankle joints and toe joints, to achieve stable walking on a slope driven by gravity. The push-off phase includes foot rotations around toe joint and around toe tip, which shows a great resemblance to human normal...
Based on the analysis of the development of recent robotic hands, proposes the design of a new under-actuated humanoid hand, the object seized drives the first segment slip inside under the forces applied by the other active joints or fingers, thus the first segment presses the active link to rotate and consequently make the second segment rotate through the passive link. This paper also evaluates...
In vitro derivation of oocytes from mouse embryonic stem cells (ESCs) would benefit the study of oogenesis. Here, we induced mouse ESCs to differentiate into oocyte-like cells by culturing adherent embryoid bodies (EBs) in different medium, including retinoic acid (RA) and follicular fluid. The extent of differentiation was evaluated through morphology and the expression of certain specific germ cell...
We present a self-learning evolutionary Prisoner's Dilemma game model to study the evolution of cooperation in network-structured populations. During the evolutionary process, each agent updates its current strategy with a probability depending on the difference feedback between its actual score and score aspiration. Each agent's score is a weighed mean of its payoff coming from its neighbors (social...
