In this study, a 2D hybrid markerless technique is proposed to estimate the lower limb joint kinematics in children with cerebral palsy (CP). The markerless methodology presented is defined as hybrid since it uses garments as “segmental markers”, specifically high-cut underwear which contributes in defining the pelvis segment and ankle socks for the definition of the foot segment. This method was validated by using a stereophotogrammetric marker-based system. Differences in the joint kinematics estimates obtained with the two techniques were within the intra-subject variability. This makes the proposed hybrid technique to be a possible economical alternative for estimating the lower limb joint kinematics of children with CP.

A PHASE FIELD APPROACH TO MODEL FRACTURE OF ARTERIAL WALLS
GÜLTEKİN, Osman; Dal, Hüsnü; HOLZAPFEL, Gerhard A (2016-06-10)
This study uses a recently developed phase-field approach to model fracture of arterial walls with an emphasis on aortic tissues. We start by deriving the regularized crack surface to overcome complexities inherent in sharp crack discontinuities, thereby relaxing the acute crack surface topology into a diffusive one. In fact, the regularized crack surface possesses the property of Gamma-Convergence, i.e. the sharp crack topology is restored with a vanishing length-scale parameter. Next, we deal with the con...
A NONINVASIVE FOCAL FIELD INTENSITY ESTIMATION METHOD USING FINITE-AMPLITUDE EFFECTS IN ULTRASOUND HYPERTHERMIA
OZYAR, MS; KOYMEN, H (1991-12-11)
A method for noninvasive in situ estimation of intensity in ultrasound hyperthermia is presented. The method employs the nonlinear theory of sound propagation in a focused ultrasound hyperthermia system in order to determine the focal field intensity, where the sound intensity levels are relatively high in the focal volume.
An in vitro human skeletal muscle model: coculture of myotubes, neuron-like cells, and the capillary network

This study reports the generation of a new human muscle tissue equivalent from skeletal muscle-derived stem cells and human umbilical vein endothelial cells (HUVECs). Skeletal muscle stem cells were isolated by the preplate technique and differentiated into neuron-like cells that were positive for neuronal beta-tubulin3 and nestin and negative for the astrocyte marker glial fibrillary acidic protein (GFAP). Coculture of skeletal muscle stem cells with the HUVECs under optimized fetal bovine serum and media ...
The algorithm of mathematical modelling for learning styles of pre-school children
Güneş, Gökhan; Şahin, Volkan (2019-01-01)
This study examines pre-school children's learning styles by utilising a mathematical model. The model uses a Euclidean geometry algorithm to generate a graphical representation of the learning styles. The algorithm of the developed mathematical model was developed as a practical application of the theoretical assumptions. Index of Learning Styles for Children (ILSC), developed by one of the researchers, has been applied to a total of 301 five-year-old children. Results of the study indicate that children u...
An Information Theoretic Approach to Classify Cognitive States Using fMRI
Onal, Itir; Ozay, Mete; Firat, Orhan; GİLLAM, İLKE; Yarman Vural, Fatoş Tunay (2013-11-13)
In this study, an information theoretic approach is proposed to model brain connectivity during a cognitive processing task, measured by functional Magnetic Resonance Imaging (fMRI). For this purpose, a local mesh of varying size is formed around each voxel. The arc weights of each mesh are estimated using a linear regression model by minimizing the squared error. Then, the optimal mesh size for each sample, that represents the information distribution in the brain, is estimated by minimizing various inform...
