Bats lower the emission SPL when approaching a target. The SPL reduction has been explained by intensity compensation which implies that bats adjust the emission SPL to perceive the retuning echoes at the same level. For a better understanding of this control mechanism we recorded the echolocation signals of four Myotis myotis with an onboard microphone when foraging in the passive mode for rus...

This paper examines possibilities and consequences of introducing variability with respect to pricing, accounting, and way of payment into software product lines for developers, vendors, and customers. The global goal is the derivation of an extensible conceptual framework for vendors of SPLs which adds relevant economic variability to the SPL. The capability of economic methods for pricing and...

The software product line (SPL) community defines SPLs not only by technical aspects like configurability and code reuse among product line variants, but also by the engineering process that accompanies the development. This paper discusses the question whether this engineering process is a mandatory property of SPLs; it concretely examines the Linux Kernel, which is not being developed accordi...

The goal was to identify sound pressure level (SPL) at the neonatal intensive care unit (NICU) and inside the incubator of a teaching hospital of a public university from São Paulo - SP, Brazil. SPL inside the NICU and the incubator were measured using four dosimeters in January/2010. SPL at the NICU varied from 52.6 dBA to 80.4 dBA and inside the incubator, from 45.4 dBA to 79.1 dBA. SPL both ...

Drosophila atonal (ato) is required for the specification of founding R8 photoreceptors during retinal development. ato is regulated via dual eye-specific enhancers; ato-3' is subject to initial induction whereas 5'-ato facilitates Notch-mediated autoregulation. Notch is further utilized to induce bHLH repressors of the E(spl) locus to restrict Ato from its initial broad expression to individua...

A dramatic example of a phenotypic interaction that involves neurogenic loci during Drosophila imaginal development is the synergistic impact of split (spl), a recessive allele of the Notch locus, and E(spl)D, a dominant gain-of-function allele of the Enhancer of split locus, on morphogenesis of the compound eye. Screens for mutations that relieve the enhancing effect of E(spl)D on spl have yie...

Techniques to model software product lines (SPLs), using feature models, usually focus on a single SPL. Larger SPLs can also be built from smaller SPLs which results in a dependency between the involved SPLs, i.e., one SPL uses functionality provided by another SPL. Currently, this can be described using constraints between the involved feature models. However, if multiple differently configure...

It is accepted that noise pollution has a major impact on health, such as physical, physiological, psychological and performance related effects, all over the world. This study aims to evaluate noise pollution in four urban parks located in Sanandaj City, Iran and to zone it in GIS environment. Sound pressure level (SPL) and maximum sound level (Lmax) were measured at 45 points (each point was ...
