Recent researches on energy efficient coverage configuration in wireless sensor networks mainly address the goal of 100% or near 100% coverage preserving. However, we find that a small percentage of loss of coverage, which is acceptable in many applications, can result in dramatic increase in energy savings. Therefore, in this paper percentage coverage rather than complete coverage is selected ...

Many methods have been used in an effort to elucidate any change that may occur in collagen plus ground substance in the group designated "collagen disease." The electron microscope furnishes fine morphological detail, and it was hoped that a correlation could be established between the configuration of the collagen fibril ends and the type of disease, which would shed light on the processes in...

The theory of Teaching for Abstraction was used to construct a unit for teaching percentages in Grade 6. The unit focused on percentage as a multiplicative relationship and put more emphasis on why percentages are used than on how they are calculated. Analysis of the data collected showed that many students did learn to apply percentages meaningfully, although the level of achievement was not a...
