Often simple metrics are used to summarise complex patterns in stream benthic ecology, thus it is important to understand how well these metrics can explain the finer-scale underlying environmental variation often hidden by coarser-scale influences. I sampled 47 relatively pristine streams in the central North Island of New Zealand in 2007 and (1) evaluated the local-scale drivers of macroinver...

Unchanging physicochemical conditions and nutrient sources over long periods of time in cave and karst subsurface habitats, particularly aquifers, can support stable ecosystems, termed autochthonous microbial endokarst communities (AMEC). AMEC existence is unknown for other karst settings, such as epigenic cave streams. Conceptually, AMEC should not form in streams due to faster turnover rates ...

We have developed a 1/1.7-inch 20Mpixel back-illuminated stacked CMOS image sensor with parallel multiple sampling plus the two simultaneous output streams. This sensor has achieved the RMS random noise of 1.3ewith the parallel multiple sampling and the two simultaneous output streams of 4Mpixel for a movie mode and 16Mpixel for a still mode with a 2.3Gb/s/lane high-speed interface. The stacked...

The emergence of dynamic information sources – including sensor networks – has led to large streams of real-time data on the Web. Research studies suggest, these dynamic networks have created more data in the last three years than in the entire history of civilization, and this trend will only increase in the coming years [1]. With this coming data explosion, real-time analytics software must e...

Studying organizational configurations on the one hand and the dynamics of organizational change on the other hand are dominant topics of interest in the information systems (IS) discipline. Studies in each of these research streams take advantage of various well-established theoretical lenses from reference disciplines such as management science. In this study, we take a closer look at archety...

Generalized multiple description coding (GMDC) is source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may produce a useful reconstruction. This paper reports on applications of two recently proposed methods for GMDC to image coding. The first produces statistically correlated streams such that lost streams can be estimated from the received...

There is growing recognition that information literacy is a critical skill for educational and workplace success, engagement in lifelong learning, and civic participation. To be considered for allocations of financial and human resources, information literacy must become a policy priority for institutions and societies. Although there has been some progress in this area since 1974, when the ter...

We examine the requirements and the available methods and software to provide (or imitate) uniform random numbers in parallel computing environments. In this context, for the great majority of applications, independent streams of random numbers are required, each being computed on a single processing element at a time. Sometimes, thousands or even millions of such streams are needed. We explain...

The MPEG-2 International standard consists of three layers: audio, video and systems [2]. The audio and the video layers define the syntax and semantics of the corresponding "elementary streams." The systems layer supports synchronization and interleaving of multiple compressed streams, buffer initialization and management, and time identification. RFC 2250 [3] describes packetization technique...
