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 ...

The performance of women agribusiness cooperatives in Oyo State, Nigeria was assessed in this study. The study employed a multi-stage sampling technique to select 6 women cooperative groups (aggregating to 175 individuals); 36 individual women; and 4 institutions across 6 LGAs in two agricultural zones of the State. Findings show that majority (55.6%) of the respondents belong to processing org...

Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...

Cooperative and gradual covering are two new methods for developing covering location models. In this paper, a cooperative maximal covering location–allocation model is developed (CMCLAP). In addition, both cooperative and gradual covering concepts are applied to the maximal covering location simultaneously (CGMCLP). Then, we develop an integrated form of a cooperative gradual maximal covering ...
