Robotic arms become more common in daily life. However, the physical human-robot interaction still needs to be improved. Therefore, I examined which algorithms can improve the interaction in a joint task of a robotic agent and a human, in which they moved an object together. Three algorithms were examined on a robotic manipulandum, namely the first where the robotic agent produced forces toward...

The filling radius function R of Gromov measures the minimal radii of van Kampen diagrams filling edge-circuits w in the Cayley 2complex of a finite presentation P. It is known that the Dehn function can be bounded above by a double exponential in R and the length of the loop, and it is an open question whether a single exponential bound suffices. We define the upper filling radius R(w) of w to...

background: there is inconsistent information about the role of psychological factors in the incidence of reflex sympathetic dystrophy (rsd) in patients with distal radius fractures. the present study was thus undertaken to evaluate the relationship between some of these factors and the occurrence of reflex sympathetic dystrophy in patients with distal radius fracture.   methods: one hundred an...

conclusions in treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice. results sf-36 test demonstrated a better general health (p < 0.001), mental health (p = 0.006), physical functioning (p < 0.001), social functioning (p < 0.001) and energy/fatigue (p < 0.001) in lcp group...

Owing to the meshless and local characteristics, moving least squares (MLS) methods have been used extensively to approximate the unknown function of partial differential equation initial boundary value problem. In this paper, based on matrix analysis, a sufficient and necessary condition for the existence of inverse of coefficient matrix used in MLS methods is developed firstly. Then in the li...

The word error rate (WER) of soft-decision-decoded binary block codes rarely has closed-form. Bounding techniques are widely used to evaluate the performance of maximum-likelihood decoding algorithm. But the existing bounds are not tight enough especially for low signal-to-noise ratios and become looser when a suboptimum decoding algorithm is used. This paper proposes a new concept named square...

The nonrelativistic many-electron system in the forward, exchange and BCS approximation is considered. In this approximation, the model is explicitly solvable for arbitrary space dimension d. The partition function and the correlation functions are given by finite-dimensional integral representations. Renormalization effects as well as symmetry breaking can be seen explicitly. It is shown that ...

We consider a multidimensional optimization problem in the framework of tropical mathematics. The problem is formulated to minimize a nonlinear objective function that is defined on vectors in a finitedimensional semimodule over an idempotent semifield and calculated by means of multiplicative conjugate transposition. We offer two complete direct solutions to the problem. The first solution con...
