Sirius ASTRONOMY AND ASTROPHYSICS Search for companions around Sirius ⋆
Since the discovery of Sirius-B about 130 yr ago, there have been several claims of a possible second companion around the brightest star Sirius-A. Such a companion could, in particular, be responsible of the suspected colour change of the star, now strongly suggested from two independent historical sources. We reported here on a new observation of the sky region around Sirius, to search for su...

Figure A presents the energy efficiency (performance/watt) for each accelerator platform across four services of the Sirius pipeline, normalized by the performance/watt achieved by using all cores on a multicore CPU by query-level parallelism. Here performance is defined as 1/latency. The power (TDP) for each accelerator platform can be found in Table A. The FPGA has the best performance/watt, ...

The innovative approach lies on declarative descriptions. All shape characteristics and behaviors can be easily configured with a minimum technical knowledge. The editors are defined by a model which defines the complete structure of the modeling workbench, its behavior and all the edition and navigation tools. This description is dynamically interpreted using GMF runtime to materialize the wor...
متن کاملThe Eigenoption-Critic Framework
Eigenoptions (EOs) have been recently introduced as a promising idea for generating a diverse set of options through the graph Laplacian, having been shown to allow efficient exploration Machado et al. [2017a]. Despite its first initial promising results, a couple of issues in current algorithms limit its application, namely: 1) EO methods require two separate steps (eigenoption discovery and r...
