To obtain a picking and planting integrated transplanting mechanism (PITM) with ideal trajectory shape, reasonable operating attitude, compact structure for vegetable pot seedling transplanting, symmetrical structural PITM composed of two planetary carriers driven by cam–noncircular gear combination was proposed in this paper. In accordance the requirements agronomy, shape motion attitude end t...

We present an analysis of the spatial covariance structure of an articulated motion prior in which joint angles have a known covariance structure. From this, a well-known, but often ignored, deficiency of the kinematic skeleton representation becomes clear: spatial variance not only depends on limb lengths, but also increases as the kinematic chains are traversed. We then present two similar Ga...

We calculate the shape of the photon spectrum for B → Xs + γ decay in the presence of a background chromomagnetic field for the case of SU(2) gauge group. The effect of the external field resembles the Zeeman effect the parton model peak is split into two slightly assymetric peaks, located around the kinematic endpoint. We investigate the analytic properties of the spectrum and calculate the to...

This paper deals with coordinated tasks for mobile nonholonomic manip-ulators. The systems are composed of a nonholonomic mobile platform and a simple kinematic chain holonomic arm. First, concepts such that redundancy and singular conngurations are deened. Then, reduced diierential models are introduced. It is then possible to work with a set of independant task coordinates. Applications follo...

new structural, metamorphic, finite strain and kinematic vorticity data for granitic gneiss and metavolcano-sedimentary rocks of thetanumaharea in the arabian shield in saudi arabia reveal a history of deformation reflecting different tectonic regimes. kinematic analysis shows their relationship to the nappe contacts between the granitic gneiss and metavolcano-sedimentary rocks and explains the...

background: patellofemoral pain syndrome (pfps) is one of the most frequent causes of anterior knee pain in adolescents and adults. this disorder can have a big effect on patients’ ability and quality of life and gait.   methods: this review included all articles published during 1990 to 2016. an extensive literature search was performed in databases of science direct, google scholar, pubmed an...

The subject of the research is optimization mechanism cross planer. In article, on basis condition closed contours, equations projection links corresponding coordinate axes are compiled. A functional relationship has been established between kinematic parameters characterizing movement input and output mechanism. obtained numerical calculations presented in form graphic dependences. aim work op...

Upper extremity rehabilitation exoskeletons are the key devices for stroke patients with movement function disorders. Based on configuration synthesis and optimum principles of 4-DOFs upper limb exoskeleton mechanisms, an mechanism compatible were presented. When was worn to extremity, a kinematic chain two closed loops formed. Moreover, equations established position solution method addressed....
