Let V be a finite set of n elements and F = {X1, X2, . . . , Xm} a family of m subsets of V. Two sets Xi and Xj of F overlap if Xi∩Xj 6= ∅, Xj \ Xi 6= ∅, and Xi \ Xj 6= ∅. Two sets X, Y ∈ F are in the same overlap class if there is a series X = X1, X2, . . . , Xk = Y of sets of F in which each XiXi+1 overlaps. In this note, we focus on efficiently identifying all overlap classes in O(n + ∑m i=1...

In this paper we give a systematic analysis of the relationship between imbalance and overlap as factors influencing classifier performance. We demonstrate that these two factors have interdependent effects and that we cannot form a full understanding of their effects by considering them only in isolation. Although the imbalance problem can be considered a symptom of the small disjuncts problem...

1. In undissected, freely mobile earthworms the sensory input for tactile stimulation to the MGF and LGF shows a region of overlap occupying a number of segments behind the clitellum. The average number of overlapping segments from a sample of 14 worms was 13 (range 0-28). 2. The overlap zone consists of segments from which both LGF and MGF spikes can be elicited. 3. Increasing stimulus intensi...

one of the main features of high throughput computing systems is the availability of high power processing resources. cloud computing systems can offer these features through concepts like pay-per-use and quality of service (qos) over the internet. many applications in cloud computing are represented by workflows. quality of service is one of the most important challenges in the context of sche...

Last years, Wavelet Packet Modulation (WPM) or Wavelet Packet Transform based Orthogonal Frequency Division Multiplexing (WPT-OFDM) have been introduced to wired and wireless communication fields as efficient Multicarrier Modulation (MCM) techniques. The wavelets have interesting features such as flexibility, compatibility and localization in both time and frequency domains with no need to use ...

asthma and chronic obstructive pulmonary disease (copd) are highly prevalent chronic diseases in the general population. both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. however, the distinction between the two obstructive diseases is not always clear. multiple epidemiological studies demonstrate that in elderly people with o...

Our paper deals with the information system design when several responsibilities share a common subset of information. First, we show how to define information overlap situations between these responsibilities. Then we focus on these situations in order to understand how the responsibility areas can avoid information coordination misunderstandings.The study of these situations shows how to defi...
