The motion of nonholonomic mobile manipulators (NMMs) is inherently constrained by joint limits, velocity self-collisions and singularities. Most planning algorithms consider some the aforementioned constraints, however, a unified framework to deal with all them lacking. This paper proposes solution for kinematic trajectory tracking redundant NMMs that include constraints needed practical imple...

Zusammenfassung Dieser Beitrag zeigt ein Konzept für eine fünfachsige Nano-Koordinatenmessmaschine zur Messung auf stark gekrümmten asphärischen und frei geformten optischen Oberflächen in einem Messvolumen von 25 mm × 5 25\hspace{0.1667em}\text...

Abstract Background Spinal muscular atrophy (SMA) is an autosomal-recessive motor neuron disease leading to dysfunction of multiple organs. SMA can impair the quality life (QoL) patients and family. We aimed evaluate QoL children with their caregivers identify factors associated in a cross-sectional study conducted China. Methods recruited 101 aged 0–17 years from children’s hospital Twenty-six...

We consider the approach to unsupervised learning whereby a normal mixture model is tted to the data by maximum likelihood. An algorithm called NMM is presented that enables the normal mixture model with either restricted or unrestricted component covariance matrices to be tted to a given data set. The algorithm automatically handles the problem of the speciication of initial values for the par...

Two new perovskite oxychalcogenides, Ca2CuFeO3S and Ca2CuFeO3Se, have been synthesized in evacuated quartz tubes. They crystallize in P4/nmm space group with lattice parameters a = 3.8271(1), c = 14.9485(2) Å and a = 3.8605(1), c = 15.3030(2) Å for Ca2CuFeO3S and Ca2CuFeO3Se, respectively. They appear to be the first layered chalcogenide perovskites involving calcium and are structural analogs ...

Gereç ve yöntemler: Bu çalışmada 17 taze donmuş kuzu lomber omurgası (sakrum T12’yi içeren) kullanıldı. Biyomekanik test aksiyel kompresyon test cihazı ile yapıldı. Aksiyel kompresyon tüm numunelere 5 mm/dk. yükleme hızı ile uygulandı. Özel dizayn edilmiş fikstür ile 8400 Nmm tork oluşturuldu. Fikstür aksiyel yönde fleksiyon, ekstansiyon, sağ ve sola eğilme pozisyonlarında yüklenme uygulanacak ...
