In this paper, we assess the practicability of Hash Sieve, a recently proposed sieving algorithm for the Shortest Vector Problem (SVP) on lattices, on multi-core shared memory systems. To this end, we devised a parallel implementation that scales well, and is based on a probable lock-free system to handle concurrency. The probable lock-free system, …

® Sieving 5.1 Introduction Sieving is an obvious means of classification and it has been used since early Egyptian times for the preparation of foodstuffs. The simplest sieves would be made of some woven material but punched plate sieves are recorded in early Egyptian drawings and by 1556 Agricola is illustrating woven wire sieves [1].

Strike the side of the sieve sharply and with an upward motion against the heel of the other hand at the rate of about 150 times per minute; turn the sieve about one-sixth of a revolution at intervals of about 25 strokes. After hand sieving all the material for one minute, determine the weight of the material passing the sieve (the material is ...

The sieving method separates solid particles in a mixture based on particle size using a succession of sieves with varying opening sizes. To accomplish efficient and precise separation, this method entails multiple phases. Sieve Selection: The first step is to choose the suitable sieves with various mesh sizes. The mesh size is the number of ...

Aromatic polyamides (aramids) are broadly used to manufacture desalination membranes; however, they are rarely considered for gas separation. Here, we report precise hydrogen sieving in …

The particles on the sieve cloth are dispersed briefly by the air jet at the cover - even before they are pulled downwards through the sieve cloth by the suction of the vacuum cleaner. The effect: the fine material is separated quickly and effectively. The coarse material remains on the sieve and is reweighed at the end of the sieving process.

The optimal sieving parameters of RAP were 20 Hz, 3 mm, and 10°, respectively, for frequency, amplitude, inclination. The optimum sieve inclination of aggregate was 20° higher than that of RAP. The deviation between the sieving efficiency of the DEM simulation test and the plant sieving test was within 15%, indicating that the …

Sieving powders for the SLS printing process is a developing process that is being done in two separate stages. The first stage is the powder preparation stage, whereby producers of these plastic/polymer powders, manufacture and then sieve the powders into the 200um over 50um size range. The second stage where the powder is sieved is during the ...

Abstract. The Number Field Sieve (NFS) is the state-of-the art algorithm for integer factoring, and sieving is a crucial step in the NFS. It is a very time-consuming operation, whose goal is to collect many relations. The ultimate goal is to generate random smooth integers mod N with their prime decomposition, where smooth is defined on the ...

Sieving is often thought of as the Cinderella of particle size analysis. Throughout its history, sieving has been deployed in many fields. (By the way, it is still used for grading grain.) For example, concrete formulations depend on sieving, and quality control in powder production often depends on sieving. Other uses of this technique are …

II.B.1 Sieving. Sieving is one of the oldest methods of analysis, but the particle size measured is ill defined. Sieves are made from woven wire, from plates with holes punched in them, or by electroforming holes in a plate. A quantity of the powder is placed on top of the sieve, which is usually vibrated so that the smaller particles fall ...

Tap sieving is a particle size gradation technique that combines a circular horizontal movement with a tapping action. The sieving machine holds a stack of sieves, each with varying mesh sizes. As the sieves rotate, a mechanism at the top of the sieve stack repeatedly taps the stack, inducing a vertical vibration.

Threshing, winnowing, and sieving grain was a part of daily life from Genesis until the early 1900's. The fact that there are dozens of allusions to it in the Bible reflects both the daily life of the people, and the fact that God expects us to learn spiritual lessons from our daily lives. Endnotes.

Tap sieve shakers are specified in various standards for particle size analysis. The number of comparisons between particles and sieve apertures is substantially lower in tap sieve shakers than in vibratory sieve shakers (2.5 s-1 as compared to ~50 s-1) which results in longer sieving times. On the other hand, the tapping motion gives the ...
