The pre-experiment of the present study revealed that polyurethane (PU) synthesized using poly (hexamethylene carbonate) glycol (PHC) has high melt viscosity and is difficult to process. Therefore, (trimethylene (PTC) was employed synthesize a PU product with low viscosity. First, four types thermoplastic (TPU) were formed through one-step solvent-free synthesis. TPU presented in format “TPU-X-...

In this paper, a framework of player segmentation, tracking, highlighting and team classification in soccer game video is proposed. Main contributions consist of: 1) playfield modeling combining the Gaussian model with the dominant color extraction to segment the players/referees; 2) mean shift-based tracking with soft constraints from the foreground map to alleviate the shortcomings in handlin...

We use rich brand level retail data to demonstrate that the firm size distribution in Carbonated Soft Drinks is mainly an outcome of the degree to which firms own a portfolio of brands across segments of the market, and not from performance within segments. In addition, while the number of firms in each segment is limited by segment size relative to sunk cost and competition in a segment, idios...

Valveless pumping refers to nonzero mean flow of fluid within a closed loop of viscoelastic tubing, when a compliant section of the loop is rhythmically compressed at particular frequencies. Valveless pumping is thought to play a role in blood circulation in embryos and in cardiopulmonary resuscitation (CPR). Heretofore, the physical mechanism causing valveless pumping has remained a mystery. W...

Callus distraction using bone segment transport systems is an applied process in the treatment of bone defects. However, complications such as muscle contractures, axial deviation and pin track infections occur in the treatment process using the currently available devices. Since successful treatment is influenced by the applied distraction force, knowledge of the biomechanical properties of th...

Soft stabilization has an important role in the treatment of the degenerative lumbar spine. Fusion of one or two motion segments may not make a big difference in the total range of motion of the lumbar spine, but preserving flexibility of a motion segment may prevent adjacent segment disease and may permit disc replacement, even when facet joints need to be excised. If a favorable environment i...
