Pediatric vascular anomalies can be generally classified into two broad categories: hemangiomas and everything else. More specifically, clinicians must understand the difference between hemangiomas (and a handful of other biologically active, proliferative vascular anomalies) and biologically inactive, non-proliferative vascular malformations.
This paper discusses the relationships among the optimization problem formulations which optimize the forecasting accuracy indices, MAPE, MAD and RMSE, respectively. The paper proposes the base optimization problem formulation that is equivalent to all the optimization formulations based on the forecasting accuracy indices, MAPE, MAD and RMSE. The findings of this paper ensure these different optimization...
Simultaneous Localization and Mapping (SLAM) addresses the problem of a robot navigating and acquiring spatial models of initially unknown environments, without an absolute localization means. To solve this problem, we propose a mapping system that builds feature-based geometrical maps by applying a modified Particle Swarm Optimization (PSO) algorithm. Particles are defined as the location of individual...
A portable VSAT terminal with tracking ability is presented for C band satellite communication on moving jets, marine vehicles or mobiles. Firstly, the system specifications have been analyzed using engineering system approach. In the second part, some critical technologies adopted in the system, like antenna, integration with RF front end, spread spectrum, hybrid tracking system, DOA algorithm and...
