This study has presented the End to End (E2E) upper bound capacity limits for high performance mesh nodes that can be deployed in rural and remote areas. The achievable capacity limits for both irregular and clustered placements of nodes have been analytically derived. Numerical results based on the data sheets of IEEE 802.11a/n standards reveal the efficacy of such designs to typical rural net...

With the opening of the long-awaited Boyne Valley Centre in Summer 1997, the time has perhaps come to reassess the relationship between heritage and tourism in Ireland. In recent years, particularly since the start of the 1990s, there has been considerable debate and controversy about heritage issues, illustrating a high degree of public interest in the field. This paper outlines the main featu...

Numerous lateralization studies have reported that word length has a stronger effect in the left visual field (LVF) than in the right visual field (RVF) for right-handed people due to hemispheric asymmetry for language processing. Alternatively, early perceptual learning theory argued that the length effects might depend on the frequency of having read words at various lengths displayed at diff...

Virtual characters with a realistic, human-like appearance are increasingly being used in video games and animation. However, increased realism does not necessarily imply increased acceptance and factors such as aberrant facial expression may evoke the Uncanny Valley phenomenon. In humans, personality traits such as anger, callousness, coldness, dominanc e, being unconcerned, and untrustworthin...

Modeling intonation, i.e., specifying adequate fundamental frequency (F0) contours, remains a challenging task for speech synthesis systems. This paper discusses the development of a system for phonetically specifying intonation contours for German. It deals with the problem of translating an abstract phonological representation of intonation namely the tone-sequence model into a concrete phone...

Ridges and valleys are useful geometric features for image analysis. Different characterizations have been proposed to formalize the intuitive notion of ridge/valley. In this paper, we review their principal characterizations and propose a new one. Subsequently, we evaluate these characterizations with respect to a list of desirable properties and their purpose in the context of representative ...

Generation of large currents, versatile functionality, and simple structures are of fundamental importance in the development of adiabatic quantum pump devices with nanoscale dimensions. In the present study, we propose an adiabatic quantum pump with a simple structure based on molybdenum disulfide, MoS2, to generate large spin and valley resolved currents. We show that pure and fully polarized...

Tethersonde, lidar, aircraft, and surface chemistry measurements from an intensive field campaign (Pacific ’93) in the Lower Fraser Valley (LFV) demonstrate the daytime advection of pollutants into a lake-filled valley adjoining a broad urbanized coastal valley. On three separate days (immediately before, during, and after a pollutant episode), elevated concentrations of ozone (O3) in the narro...

heavy metal pollution plays an important role in global biodiversity decline. however, there is paucity of information concerning the effects of metals on amphibians. in the present study, investigations were made on the accumulation of heavy metals, copper (cu) and lead (pb) in water, sediment and tadpoles inhabiting the water bodies of barak valley, assam. tadpoles of six different anuran spe...

to identify arbuscular mycorrhiza fungi (amf) associated with crataegus pontica c. koch, 54 soil samples were collected from the rhizosphere of this plant in ilam province, western iran. isolation of mycorrhizal spores was conducted by wet sieving followed by centrifuge. amf were identified based on morphological characteristics of spores. in this study, 13 species of amf belonging to five gene...
