Recently, there has been significant interest in developing the modular multilevel converter (MMC) based DC grids in the power industry.However, the immature DC circuit breaker (DCCB) technology hampers the development of DC grids in overhead lines transmission field.The full controlled power electronic devices based hybrid DCCB has sten jacket m b
A Novel Generic Ball Recognition Algorithm Based on Omnidirectional Vision for Soccer Robots
It is significant for the final goal of RoboCup to realize the recognition of generic balls for soccer robots.In this paper, a novel generic ball recognition algorithm based on omnidirectional vision is proposed by combining the modified Haar-like features and AdaBoost learning algorithm.The algorithm is divided into offline training and online rec
Negative life events vary by neighborhood and mediate the relation between neighborhood context and psychological well-being.
Researchers have speculated that negative life events are more navy drapery fabric common in troubled neighborhoods, amplifying adverse effects on health.Using a clustered representative sample of Chicago residents (2001-03; n = 3,105) from the Chicago Community Adult Health Survey, we provide the first documentation that negative life events are h
Persistent Postural-Perceptual Dizziness: A Matter of Higher, Central Dysfunction?
Persistent postural-perceptual dizziness (PPPD) is the most common vestibular disorder in the age group between 30 and 50 years.It is considered to be based on a multisensory maladjustment involving alterations of sensory response pattern including vestibular, visual and motion stimuli.Previous data supported a link between vestibular and pain mech
