The benchmarking of window-based RDF Stream Processing (RSP) engines has recently attracted the attention of the Stream Reasoning community. Solutions like LSBench, SRBench and CSRBench tried to fulfill the need of shared practices for RSP engine evaluations. However, an infrastructure for the systematic comparison of existing systems is still missing. In this paper, we propose the requirements...

i Executive summary High power proton accelerators (HPPAs) are at the heart of many future large-scale scientific facilities such as a spallation-neutron source, Neutrino Factory and the Muon Collider, high energy physics at the energy or intensity frontier, accelerator driven sub-critical systems, and the transmutation of nuclear waste. Controlling beam-loss induced machine activation during i...

Evolutionary psychology, memetics and models of cultural evolution focus on reproductive success. I will argue that fitness should in fact focus on differential persistence of entities instead of differential reproductive success of replicators. Understanding evolution as such shifts the nature of adaptation from reproduction to persistence, changing the means by which representational powers w...

[Purpose] The purpose of this study was to compare the center of mass during sit-to-stand and stand-to-sit activities in the timed up and go test between healthy subjects and patients with stroke. [Subjects and Methods] Thirty healthy participants and thirty patients with stroke volunteered for this study. Acceleration of the center of mass was measured using a wireless tri-axial accelerometer ...

BACKGROUND AND PURPOSE We investigated cerebral blood flow regulation in astronauts before and after flights. We hypothesized that autoregulation would be different before flight and after flight between nonfinishers and the finishers of a stand test. METHODS Twenty-seven astronauts from shuttle missions lasting 8 to 16 days underwent a 10-minute stand test: 10 days before flight, 1 to 2 hour...

in order to study the qualitative, quantitative characteristics of a pure common populus alba stand in polkalleh & a mixed stand of populus alba & populus nigra in karchegan, two 30-year-old stands were selected with a plantation interval ( spacing) of 2.5 × 1.5 m in each of which 30 pcs of 2 are samples were randomly selected. in each sample pc all the trees diameters were measured using a dia...
