New wireless sensor network applications (e.g., military surveillance) require higher reliability than a simple best effort service could provide. Classical reliable transport protocols like Transmission Control Protocol (TCP) are not well suited for wireless sensor networks due to both the characteristics of the network nodes (low computing power, strong energy constraints) and those of the ma...

the host plant quality not only influences on herbivorous insects but also indirectly could impact on their natural enemies’ performance. the current study was conducted to determine the effect of different nitrogen fertilization levels of canola (brassica napus l.) on life table parameters of the predatory gall midge, aphidoletes aphidimyza rondani; diptera: cecidomyiidae, in feeding of mustar...

In last decades, New Product Development (NPD) process has become crucial for the company success. Many efforts have been paid in order to identify methods and tools able to improve NPD, but successful models are still missing or not easily followed. Companies find difficult to implement comprehensive models for improving their NPD process, and often they aren’t even aware on how they actually ...

This paper presents a functional-analytic framework for sampled-data control systems with generalized samplers and holds. Notions of lifting-based transfer functions and their matrix representations are introduced and several properties of the systems are derived. This framework covers a large class of samplers and holds. In the latter half of this paper, the presented framework is applied to a...

a variety of anthropometric and training characteristics have been identified as predictor variables for race performance in endurance and ultra-endurance athletes. anthropometric characteristics such as skin-fold thicknesses, body fat, circumferences and length of limbs, body mass, body height, and body mass index were bi-variately related to race performance in endurance athletes such as swim...
