EXECUTIVE SUMMARY OF THE ASIA-PACIFIC COUNTRIES WITH SPECIAL NEEDS DEVELOPMENT REPORT 2019: STRUCTURAL TRANSFORMATION AND ITS ROLE IN REDUCING POVERTY
Also, their structural transformation has followed a different pattern to that of the East Asian “miracle economies”. (...) Such structural transformation tends to be more conducive for employment generation and poverty reduction. 12. Structural transformation must also take place in a socially and environmentally sustainable way.

A transform with 16bit inputs for multiplies and up to 21 bit intermediate results during transform and quantization operations, and an all 16 bit transform. (...) The assumptions for the forward transform inputs (1a and 1b) are values in the range [-255, 255], while the assumptions for inverse transform inputs (4a and 4b) are values generated by the forward transform. (...) One change from tml5.91 is that the dequantization is performed before the inverse transform. Chroma transform The first transform is the same as above.

TRANSPORT OF TRANSFORMERS WITH GAS CYLINDERS
However, as the transformers are not gas- tight, low quantities of gas are constantly supplied through a pressure regulator from a gas cylinder connected to the transformer. So far, transformers have been transported by sea under UN 3363, Class 9. (...) A special provision should be assigned to UN 3538 laying down safety requirements for pressurizing transformers with gas. Pictures with examples of such transformers are included in the Annex. 7.

PROPOSAL TO AMEND SPECIAL PROVISION XXX AS ADOPTED AT THE 56TH SESSION BASED ON INFORMAL DOCUMENT INF.53
On return home the United Kingdom undertook some research into the transport of transformers with attached gas bottles. The summary of findings was as follows: (a) Some transformers have higher gas pressures than the 35 kPa in the adopted text; (b) Most transformers are shipped with dry air as the gas (possibly 95 %); (c) There is the potential to use other gases not listed in the special provision; * 2020 (A/74/6 (Sect.20) and Supplementary, Subprogramme 2) United Nations ST/SG/AC.10/C.3/2020/49 Secretariat Distr.: General 15 April 2020 Original: English ST/SG/AC.10/C.3/2020/49 2 (d) The purpose of the gas is to ensure that no moisture can penetrate into the transformer; (e) By design transformers are liquid tight but not gas tight, so the gas will leak away over time; (f) Some transformers will be transported full of oil with a gas blanket, others will be transported without oil. In both cases the gas performs the same function; (g) The gas bottles are used to top up the gas in the transformer so there is no continuous flow from the bottle to the transformer; (h) Transformers can vary in size from around 2 tonnes to 30 to 40 tonnes and occasionally up much larger (biggest that we have found is 192 tonnes); (i) Transformers are designed to operate in the open so are not normally packed; (j) Transformers have been transported like this for well over 30 years; (k) There are no recorded instances of issues in transport from venting nitrogen; (l) One manufacturer is shipping a transformer every 2 to 3 days. (...) An information document will be provided with some pictures of transformers to help delegates appreciate what we are dealing with.

In that case, we need to change the 2x2 transforms to 2x4 and 4x4 transforms. Since we already know from luma processing that the DC transforms can be Hadamard transforms (because there’s no significant coding gain advantage of using DCT-like transform), we propose that the chroma DC transform should be: · 4:2:0 chroma: length-2 Hadamard transform for both rows and columns (that’s what’s currently in the standard). · 4:2:2 chroma: length-2 Hadamard transform for columns and the length-4 Hadamard transform for rows. The length-4 Hadamard transform should be the same as that used for luma, as specified in Eqn. (8-256) of document JVT-G050. · 4:4:4 chroma: length-4 Hadamard transform for both rows and columns. (...) In fact, our experiments have shown that when the color transformation matrix is considered as a decorrelation transform (like a DCT, for example), the RGB space is not the best choice.
