ASTC is one of the standard texture formats supported in OpenGL ES 3.2 and Vulkan 1.0 (and later versions), it has been increasingly used on mobile platforms (Android iOS). ASTC’s most important feature block size configuration, thereby providing a trade-off between compression quality rates. With higher number textures, however, difficult to manually determine optimal sizes each texture. To so...

The in situ block size of the rock mass may be the single most important parameter influencing the stability and strength of some underground openings. Rock masses can often reasonably be characterized by a simple size-strength classification. The actual block size distribution is the product of the interaction between the joint orientation, spacing and persistence of that rock mass. Despite th...

the statistical analysis of spatial data is usually done under gaussian assumption for the underlying random field model. when this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. one of the crucial problems in this setting is specifying the block sizes. in this paper, we present asymptotic optimal block size for separate block bootstrap to estimate the...

Experimental investigations have been conducted for determination of effectiveness of employing a combination of three particle sizes (40 nm size, 1.75 μm size and 53 μm size) of Molybdenum Disulphide as anti-wear additive in a commercial lubricant. The conformal block and disk configuration has been used to conduct experiments for determination of wear of the sliding surfaces. The performance ...

In pipelined parallel computations the inner loops are often implemented in a block fashion. In such programs, an important compiler optimization involves the need to statically determine the grain size. This paper presents extensions and experimental validation of the previous results of Andonov and Rajopadhye on optimal grain size determination.

Some practical issues in planning cross-over trials will be considered. A general approach to sample size determination for any arbitrary cross-over will be described. This also permits sample size determination when it is intended to recover inter-block information for incomplete block cross-overs. Consideration will also be given to planning to mimimize the effect of carry-over. Some aspects ...

For every v ≡ 5 (mod 6) there exists a pairwise balanced design (PBD) of order v with exactly one block of size 5 and the rest of size 3. We will refer to such a PBD as a PBD(5∗, 3). A flower in a PBD(5∗, 3) is the set of all blocks containing a given point. If (S,B) is a PBD(5∗, 3) and F is a flower, we will write F ∗ to indicate that F contains the block of size 5. The flower intersection pro...
