The percentage of time the sign is illuminated will have a large effect on overall power consumption. "YOUR Speed" driver feedback signs have become increasingly popular devices for slowing traffic and increasing workers' safety. Thanks to new technologies, these signs have become more effective and easier to deploy than ever before. For instance, improvements in sign designs that make it easie...

State space explosion is a fundamental obstacle in formal veriication of designs and protocols. Several techniques for combating this problem have emerged in the past few years, among which two are signiicant: symbolic state space search using BDDs and partial order reductions. In asynchronous systems, interleavings of independent concurrent events are equivalent, and only a representative inte...

Reward is the simplest way to motivate students in education. It can encourage students to learn and get immediate achievement. Moreover, it is also has potential to construct students’ intrinsic motivation. However, traditional rewards are often less valuable thus can’t keep motivating students, e.g. symbolic rewards like stars or stickers can’t be used by the students after the class; therefo...

Multiple factors have been identified as contributing to polyethylene wear and debris generation of the acetabular lining. Polyethylene wear is the primary limiting factor in the functional behavior and consequent longevity of a total hip arthroplasty (THA). This retrospective study reviewed the clinical and radiographic data of 77 consecutive THAs comparing in vivo polyethylene wear of two sim...

introduction: chronic nasal obstruction due to adenoid hypertrophy is a very common disorder. although the clinical assessment of adenoid hypertrophy is essential, its real value in young children is difficult to evaluate. the purpose of this prospective study was to validate a simple clinical score to predict the severity of adenoid obstruction and to evaluate the relationship between this met...

consider search designs for searching one nonzero 2- or 3-factor interaction under the search linear model. in the noisy case, search probability is given by shirakura et al. (ann. statist. 24(6) (1996) 2560). in this paper some new properties of the searching probability are presented. new properties of the search probability enable us to compare designs, which depend on an unknown parameter ?...
