Viewing angle measurements on curved displays
P. Boher,T. Leroux,V. Collomb Patton,T. Bignon,P. Blanc 한국정보디스플레이학회 2015 Journal of information display Vol.16 No.4
The simple fact that a curved display is no more flat induces new visual effects that must be studied specifically. Display viewing angle, generally referring to variation of emissive properties (luminance and color) versus viewing direction is generally affected by the curvature and must be measure accurately. In the following article, the angular distortion of a viewing angle measurement made on a curved display when using a standard viewing angle measurement system (goniometer or Fourier optics) is expressed versus spot size D, radius of curvature R and defocus H. The limits of validity of viewing angle measurements on a curved display are deduced. If the ratio D/R of the display is below 1%, the measurement errors in the angles cannot exceed 1° for all the viewing angles for a system at focus, and the accuracy of the measurements remains excellent. Out of focus, there is also no impact of the angular accuracy if the ratio H/R is below 1%. The simulations are compared to real measurements made across flat or bent brightness enhancement film and on a curved organic light-emitting diode cell phone display.
GAS-COOLED FAST REACTORS_DHR SYSTEMS, PRELIMINARY DESIGN AND THERMAL- HYDRAULIC STUDIES
Malo, J.Y.,Bassi, C.,Cadiou, T.,Blanc, M.,Messie, A.,Tosello, A.,Dumaz, P. Korean Nuclear Society 2006 Nuclear Engineering and Technology Vol.38 No.2
The Gas-cooled Fast Reactor (GFR) is one of the six reactor concepts selected within the framework of the Generation IV initiative and is the reference concept for the Commissariat $\grave{a}$ l'Energie Atomique $(CEA^1)$. Two reactor unit sizes have been considered: 600 MWth and 2400 MWth. As far as thermal-hydraulics is concerned, reactor decay heat removal (DHR) proves to be a major issue. The CEA has conducted exploratory design studies to address this issue and a reference solution for the 600MWth reactor has been recommended.

Biogenesis of the primary cilium, a cellular organelle mediating various signaling pathways, is generally coordinated with cell cycle exit/re-entry. Although the dynamic cell cycle-associated profile of the primary cilium has been largely accepted, the mechanism governing the link between ciliogenesis and cell cycle progression has been poorly understood. Using a human genome-wide RNAi screen, we identify genes encoding subunits of the spliceosome and proteasome as novel regulators of ciliogenesis. We demonstrate that 1) the mRNA processing-related hits are essential for RNA expression of molecules acting in cilia disassembly, such as AURKA and PLK1, and 2) the ubiquitin-proteasome systems (UPS)-involved hits are necessary for proteolysis of molecules acting in cilia assembly, such as IFT88 and CPAP. In particular, we show that these screen hit-associated mechanisms are crucial for both cilia assembly and cell cycle arrest in response to serum withdrawal. Finally, our data suggest that the mRNA processing mechanism may modulate the UPS-dependent decay of cilia assembly regulators to control ciliary resorption-coupled cell cycle re-entry.
