Disk or Halo white dwarfs ? Kinematic analysis of high proper motion surveys
We present an alternative method for the kinematic analysis of high proper motion surveys and discuss its application to the survey of Oppenheimer et al. (2001) for the selection of reliable halo white dwarfs (WDs). The local WD space density we estimate is ρWD ≃ 1 ÷ 2 · 10 −5 M⊙pc −3 , which is about an order of magnitude smaller than the value derived in Oppenheimer et al. (2001), and is cons...
متن کاملStatistical Matching in ‘Labour Force’ and ‘Time Use’ Surveys
Abstract. In the National Statistical Systems, some parts of the official statistics required for development planning and evidence base management are collected through sampling survey. Due to the high cost of sampling process, as well as nonresponses, it may not be possible to collect all of the expected variables in a survey.In order to obtain a comprehensive and complete source o...
متن کاملOptimizing Cyst Mapping Surveys through Statistical Analysis of Historical Data
Introduction. An important management tool for red tides or toxic Alexandrium blooms in the Gulf of Maine region is a numerical model of bloom dynamics developed at the Woods Hole Oceanographic Institution (WHOI). Each week during the bloom season, this model is run, providing a “hindcast” simulation of Alexandrium distribution and abundance for the preceding weeks and months, as well as a one-...
متن کاملStatistical Analysis of Pathological Motion Areas
In this paper we address the problem of complex events in degraded image sequences. The occurrence of these complex events causes the failure of the motion estimation process. Consequently, the sequence of operations that rely on it, such as motion compensation and motion picture restoration, will fail as well. We present a statistical analysis of such areas, as well as a taxonomy of pathologic...
متن کاملStatistical Analysis of Global Motion Chains
Multiple elements such as lighting, colors, dialogue, and camera motion contribute to the style of a movie. Among them, camera motion is commonly overlooked yet a crucial point. For instance, documentaries tend to use long smooth pans whereas action movies usually have short and dynamic movements. This information, also referred to as global motion, could be leveraged by various applications in...
