Some Remarks on Diffusion Distances
Published 2010-01-01“…As a diffusion distance, we propose to use a metric (closely related to cosine similarity) which is defined as the 𝐿2 distance between two 𝐿2-normalized vectors. We provide a mathematical explanation as to why the normalization makes diffusion distances more meaningful. …”

Brane-vector dark matter and its connection to inflation and primordial gravitational waves
Published 2024-12-01“…The brane-vector can be responsible for dark matter because it is odd under a $$\textrm{Z}_2$$ Z 2 symmetry, neutral under the Standard Model (SM) symmetries, and couples extremely weak to the SM particles due to its gravitational origin. …”

Parameter limit and finite element analysis of unequal modulus involute gear pair
Published 2024-06-01“…But used in the engineering practice in modulus differ with tooth profile angle are smaller, the formation principle of involute gear tooth surface and the gear meshing analysis of some parameters, got this kind of gear modulus, tooth number, tooth shape parameters such as coefficient of angle, depth of constraints, and through the formula deduction coefficient of the teeth, the tooth depth and the relation between the dividing circle pressure angle limit value. Based on the modeling of engineering practice and the finite element analysis through Ansys, the gear strength designed based on the limit parameters is about 2.66 times of the standard gear, which verifies the feasibility of the theory and expands the application range of this gear pair.…”

Mechanism Design and Kinematics Analysis of a Hybrid-driven Waist Rehabilitation Robot
Published 2016-01-01“…A cable-pneumatic-muscle hybrid-driven waist rehabilitation robot is designed for human waist and gait rehabilitation training.The presented data and curves indicate that the state of motion of human torso during normal walking and the rehabilitation robotics fundamental functions are confirmed.According to these,the structure of the rehabilitation robot that employed the double parallel mechanism is designed.The cable- driven parallel mechanism is chosen to drive the human lower limb,and the pneumatic muscle(PM) is chosen to twist the human waist.The adaptability and safety of the rehabilitation robot is enhanced by synthesized the features of the two actuators.The inverse kinematics are solved by using the closed-vector-circle method,and the velocity Jacobian matrix is established.In addition,the rehabilitation robotics kinematics model and the PM element thermodynamics model are established in view of the parameters of different trainers is diverse.Then the kinematics character of cables and PM during the normal walking are obtained through numerical simulation,and the force variation trend of PM elements is also simulated to verify the feasibility of mechanism.…”
