They briefed correspondents on the scope and content of the revised UN Model Convention, which will be officially launched tomorrow as part of a special high-level meeting of the Economic and Social Council on international cooperation in tax matters. (...) The speakers also responded to a number of questions from correspondents, including one concerning the lengthy period between the first and revised versions of the UN Model Convention.  (...) There was also a difference in the amount of resources available to the United Nations Committee of Experts and that available to the OECD, whose Convention was updated more frequently, he added. Another correspondent asked how the UN Model Convention tackled the issues of implementation and compliance.

(...) In this review, the model’s inputs are AQUASTAT data related to the corresponding irrigated crops: areas of harvested irrigated crops, cropping patterns and cropping intensity, converted into irrigated crop calendars. (...) The review consists in a 3-step methodology (summarized in Figure 1 below): Preparation of irrigated crop calendars by country Irrigated crop calendars by country Regional summary of the irrigated crop calendars Calculation of irrigation water requirement , calculated by the model by comparing: The water balance under non-irrigated conditions, corresponding to the actual evapotranspiration under non-irrigated conditions and calculated using available climatic datasets; and The crop water requirement based on the irrigated crop calendars and the global map of irrigation areas.

At the GCI Expert Group meeting (25 October 2022), the working group will discuss the models of tiers and recommend a suitable model. Experts are invited to share and/or present different models to the Expert Group before or during meetings. 3. After discussions of the different models, experts are expected to arrive at a consensus on one tier model suitable for grouping countries according to their performance in the GCI. a. If there is no consensus on a tiering model, all proposals will be shared with ITU management which will decide on a framework. 6 b.

Note that it would be however always possible to adapt this quantization step size for instance on each component or per residual frame type. Modeling of transform coefficient subbands Each transform coefficient subband marginal distribution is modeled as a Generalized Gaussian Density (GGD) by adaptively varying two parameters ( and ( where ( models the width of the Probability Density Function (PDF) peak (standard deviation), while ( is inversely proportional to the decreasing rate of the peak. Sometimes, ( is referred to as the scale parameter while is called the shape parameter. The GGD model contains the Gaussian and Laplacian PDFs as special cases, using (=1 and (=2, respectively. (...) However, the distributions may not change a lot for a given type along the sequence, which would allow to have pre-defined parameters per frame type without requiring to model the distribution and to avoid transmitting the parameters.

It can be shown, that, theoretically, all binary code trees are equivalent in sense of representing the entropy of the original symbols provided that each node of the corresponding trees corresponds to an appropriately initialized probability model. (...) Table 1 : Exp-Golomb codes (left) and their related models, where different models are depicted by different colors (right). (...) By using a single, unified binarization scheme, each syntax element uses at least 4 different models: 3 models switching between the first, the second and all remaining bins of the prefix bins, and one additional model for all suffix bits.
