In this paper, we first present a new important property for Bouligand tangent cone (contingent cone) of a star-shaped set. We then establish optimality conditions for Pareto minima and proper ideal efficiencies in nonsmooth vector optimization problems by means of Bouligand tangent cone of image set, where the objective is generalized cone convex set-valued map, in general real normed spaces.

OBJECTIVE (1) To measure objectively the subjective improvement in joint stiffness following intra-articular injections of corticosteroids, and (2) to record changes in joint stiffness in the first 24 hours after injection to look for changes in the physical properties of the joint that would be consistent with a crystal synovitis. METHODS The study population consisted of 15 patients having ...

In this paper, the real-time joint stiffness configuration strategy of a series parallel hybrid 7-DOF (degree freedom) humanoid manipulator with flexible joints in continuous motion is studied. Firstly, considering potential human robot accidental collision, combined safety index (MSI) and body injury thresholds, speed are optimized advance. Secondly, using hyperbolic tangent function for refer...

In order to increase the structural performance of rotary tillage knife, a badger claw toe was selected as bionic prototype and optimization design knife carried out. The similarity between badger’s tiller is 0.7073 by fuzzy algorithm, shape goodness fit final mole’s digging shovel 0.9556 MATLAB. Using 3D modeling software NX10.0, we established three-dimensional model knife. Furthermore, use W...

We measure the Galactic rotation curve and its first two vertical derivatives in the first and fourth quadrants of the Milky Way using the 21 cm VGPS and SGPS. We find tangent velocities of the atomic gas as a function of galactic longitude and latitude by fitting an analytic line profile to the edges of the velocity profiles. The shape of the analytic profile depends only on the tangent veloci...

The success of variational methods for optical flow computation lies in their ability to regularize the problem at a differential (pixel) level and combine piecewise smoothness of the flow field with the brightness constancy assumptions. However, the piecewise smoothness assumption is often motivated by heuristic or algorithmic considerations. Lately, new priors were proposed to exploit the str...

Algorithmic skeleton has received attention as an efficient method of parallel programming in recent years. Using the method, the programmer can implement parallel programs easily. In this study, a set of efficient algorithmic skeletons is introduced for use in implementing parallel genetic algorithm (PGA).A performance modelis derived for each skeleton that makes the comparison of skeletons po...

Abstract. Purpose. The work’s aim is to study the horizontal supports stiffness impact, which simulate conditions for supporting domes upper tier on von Mises trusses' stability. Methodology. A three-hinged truss' deformed scheme under applying a concentrated vertical load in ridge joint was considered. An analytical method used obtain generalized equation stability criterion determine critical...

Learning objects along with their sequencing are being studied to support efficient e-learning systems. They could solve the problem of costly reproduction of learning materials for e-learning systems. The problem arising here is related to the size and complexity of methods used to achieve the appropriate composition of learning objects in order to generate courses with pedagogic efficiency an...

We give elementary and explicit arguments to show that the geodesic ow on the unit tangent bundle of a two dimensional Riemannian manifold with constant negative curvature provides an example of a \fast" dynamo for the magnetic kinematic dynamo equation.
