introduction: in this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. a window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. material and methods: the program was...

Title of Thesis: OBSERVER-BASED FEEDBACK CONTROL FOR STABILIZATION OF COLLECTIVE MOTION Seth Ochse Napora, Master of Science, 2011 Thesis directed by: Professor Derek A. Paley Department of Aerospace Engineering Multi-vehicle control has applications in weather monitoring and ocean sampling. Previous work in this field has produced theoretically justified algorithms for stabilization of paralle...

In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...

soft-sphere discrete element method (dem) and navier-stokes equations were coupled with equations of energy for gas and solids to investigate the process of agglomeration in fluidized bed of polyethylene particles at high temperature. the newton’s second law of motion was adapted for translational and rotational motion of particles and agglomerates. the cohesive force for polyethylene particles...
