Active biphasic heat transfer enhancement in vertical natural convection
Vertical natural convection (VC), often cannot meet the high heat transfer demands due to the inherent misalignment of the direction of buoyancy (vertical) with the direction of the heat transfer (horizontal). Here we applied a novel strategy on a water based VC system to enhance the heat transfer. By adding 2% of the total volume with a low-boiling-temperature liquid (HFE-7000) and introducing a gas-liquid layer on top of the VC cell, we create a self-sustained state of pseudo-turbulence with …

Easy Acceleration with Distributed Arrays
High level programming languages and GPU accelerators are powerful enablers for a wide range of applications. Achieving scalable vertical (within a compute node), horizontal (across compute nodes), and temporal (over different generations of hardware) performance while retaining productivity requires effective abstractions. Distributed arrays are one such abstraction that enables high level programming to achieve highly scalable performance. Distributed arrays achieve this performance by derivi…

#photography #bloomScrolling #tulips #pink

a vertical format image of a bunch of pink and orange tulips in a slender glass vase and the shadow it casts on the wooden desk it is standing on while being lit by bright but dappled sunlight coming in from behind and above the tulips
horizontal format closeup of a bunch of orange and pink slightly wilting tulips with a neutral background, focusing on a particular salmon-orange tulip flower in the middle

horizontal closeup of a small bunch of light pink and yellow tulips in a glass vase in front of a white wall, lit by neutral artificial light, with some dark shadows along the edges
the same bunch of tulips as in the previous picture but turned around and zoomed in a bit
the same bunch of tulips, zoomed in even more, in a vertical format image focusing on a curled outward petal, situated in the middle between two flowers

#photography #bloomScrolling #tulips #pink

horizontal format closeup of an already wilting, light pink tulip in dappled light seen from above, focusing on the texture of the tips of its petals, against a background in very dark shadow
a vertical format image of a bunch of tulips in a glass vase, lit by dappled sunlight coming in from a window out of the picture behind them, and casting a shadow on the table their standing on in the lower part of the image
