Les plans de pistes de ski : une saison hivernale fantasmée
EchoGéoSince the creation of ski resorts, there has been a proliferation of piste maps for skiers. By analysing several French maps and a few foreign ones, we will look at the representations of the mountains, via the ski areas, that these maps convey.

A novel ensemble estimation of distribution algorithm with distribution modification strategies
Complex & Intelligent Systems, 2023 The canonical estimation of distribution algorithm (EDA) easily falls into a local optimum with an ill-shaped population distribution, which leads to weak convergence performance and less stability when solving global optimization problems.

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Measurement of night sky brightness in southern Australia
, 2011 Night sky brightness is a major source of noise both for Cherenkov telescopes as well as for wide-angle Cherenkov detectors. Therefore, it is important to know the level of night sky brightness at potential sites for future experiments.

OT 060420: A Seemingly Optical Transient Recorded by All-Sky Cameras [PDF]
, 2006 We report on a ~5th magnitude flash detected for approximately 10 minutes by two CONCAM all-sky cameras located in Cerro Pachon - Chile and La Palma - Spain. A third all-sky camera, located in Cerro Paranal - Chile did not detect the flash, and therefore

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

The Wiener-Filtered COBE DMR Data and Predictions for the Tenerife Experiment [PDF]
, 1995 We apply a Wiener filter to the two-year COBE DMR data. The resulting sky map has significantly reduced noise levels compared to the raw data: the most prominent hot and cold spots are significant at the 4-sigma level.
