In a cooperative relay network, a relay node (R) may facilitate data transmission to the destination node (D), when the latter is unable to decode the source node (S) data correctly. This paper considers such a system model and presents a crosslayer approach to jointly design adaptive modulation and coding (AMC) at the physical layer and cooperative truncated automatic repeat request (C-ARQ) pr...

Complex regional pain syndrome (CRPS) type I may occur as complication after any type of surgery for basal joint arthritis of the thumb. We investigated prospectively in an ongoing study our results after a fully standardized treatment with a total joint prosthesis under vitamin C prophylaxis.Patients with trapeziometacarpal arthritis stage II or III according to Dell, and no benefit from conse...

OBJECTIVE To investigate the validity of reduced joint counts for ultrasonographic (US) assessment of joint inflammatory activity in patients with rheumatoid arthritis (RA). METHODS Ninety-four patients with RA were included. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were recorded for each patient. The presence of tenderness, swelling and a subjective swelling s...

In this paper standing balance control of a biped with toe-joint is presented. The model consists of an inverted pendulum as the upper body and the foot contains toe-joint. The biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. To model the interaction between foot and the ground, configuration constraints are defined and utilized. To s...

In this paper, we propose a joint resource allocation algorithm for energy efficiency (EE) of a cloud radio access network (C-RAN). To tackle the joint optimization problem, we utilize a successive convex approximation (SCA) based joint antenna selection and power allocation (JASPA) algorithm. In addition, we propose an improved multi-candidate remote radio heads (RRHs) user association (MCRUA)...

Introduction: Inflammatory joint diseases are common in elderly, and regulation of joint blood flow (JBF) is important in these conditions. The aim of this study was to investigate the response of inflamed joint blood vessels to angiotensin (Ang ), a vasoconstrictor factor which has been shown to be produced in inflamed joints locally. Identification of Ang receptor subtypes in joint blood ve...

We prove an uncertainty relation, which imposes a bound on any joint measurement of position and momentum. It is of the form (∆P )(∆Q) ≥ C~, where the ‘uncertainties’ quantify the difference between the marginals of the joint measurement and the corresponding ideal observable. Applied to an approximate position measurement followed by a momentum measurement, the uncertainties become the precisi...

The kinematics and dynamics of two industrial cooperating robots are presented in this paper. The NOC (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. The joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. To this end, minimizing the cr...

In this paper we will introduce a new index of interactivity between marginal possibility distributions A and B of a joint possibility distribution C. The starting point of our approach is to equip each γ-level set of C with a uniform probability distribution, then the probabilistic correlation coefficient between its marginal probability distributions is interpreted as an index of interactivit...
