McClear: a new model estimating downwelling solar radiation at ground level in clear-sky conditions
A new fast clear-sky model called McClear was developed to estimate the downwelling shortwave direct and global irradiances received at ground level under clear skies. It is a fully physical model replacing empirical relations or simpler models used before. It exploits the recent results on aerosol properties, and total column content in water vapour and ozone produced by the MACC project (Moni...
متن کاملEstimating N -point Correlation Functions from Pixelized Sky Maps
We develop, implement and test a set of algorithms for estimating N -point correlation functions from pixelized sky maps. These algorithms are slow, in the sense that they do not break the O(N pix) barrier, and yet, they are fast enough for efficient analysis of data sets up to several hundred thousand pixels. The typical application of these methods is Monte Carlo analysis using several thousa...
متن کاملEstimating the audience level for library resources
WorldCat, OCLC’s bibliographic database, identifies books and the libraries that hold them. The holdings provide detailed information about the type and number of libraries that have acquired the material. Using this information, it is possible to infer the type of audience for which the material is intended. A quantitative measure, the audience level, is derived from the types of libraries tha...
متن کاملEstimating LASSO Risk and Noise Level
We study the fundamental problems of variance and risk estimation in high dimensional statistical modeling. In particular, we consider the problem of learning a coefficient vector θ0 ∈ R from noisy linear observations y = Xθ0 + w ∈ R (p > n) and the popular estimation procedure of solving the `1-penalized least squares objective known as the LASSO or Basis Pursuit DeNoising (BPDN). In this cont...
متن کاملEstimating Bandwidth Requirements Using Flow-Level Measurements
Bandwidth provisioning is used to dimension links so that a desired performance is met within a network (e.g. QoS metrics). Practical approaches for estimation of bandwidth needs rely on rough traffic measurements overlooking traffic fluctuations that may impact negatively on network performance. On the other hand, effective theoretical solutions for estimating bandwidth needs require traffic m...
