Test set compaction is a fundamental problem in digital system testing. In recent years, many competitive solutions have been proposed, most of which based on heuristics approaches. This paper studies the application of set covering models to the compaction of test sets, which can be used with any heuristic test set compaction procedure. For this purpose, recent and highly effective set coverin...

We address the phase ordering problem of code compaction and register assignment in a data ow graph compiler. During register assignment, we take into account the instructionlevel parallelism available. Symbolic variables in straightline code are allocated to register set/memory location pairs which maximally preserve the freedom available for code compaction. Whenever necessary, spill code is ...

During embryonic development, tissues deform by a succession and combination of morphogenetic processes. Tissue compaction is the morphogenetic process by which a tissue adopts a tighter structure. Recent studies characterized the respective roles of cells' adhesive and contractile properties in tissue compaction. In this review, we formalize the mechanical and molecular principles of tissue co...

[1] We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or ...

Silica refractory bricks are used especially in the metallurgical industries, due to desirable properties such as particularly their high melting point and their rigidity and strength at high temperatures. In this research, different amount of SiC were added to Silica refractory containing different binders such as Borax, Boric acid, Calcium nitride, Sodium tri poly phosphate, Sodium hexametaph...

LSM-tree has been widely used in cloud computing systems by Google, Facebook, and Amazon, to achieve high performance for write-intensive workloads. However, in LSMtree, random key-value queries can experience long latency and low throughput due to the interference from the compaction, a basic operation in the algorithm, to caching. LSM-tree relies on frequent compaction operations to merge dat...

soil compaction is one of the most prevailed limitations for crop growth. the use of organic matters as fertilizer on agricultural soils can reduce the effects of soil compaction and provide the nutrients for the plants. so, a factorial experiment was carried out in a randomized complete blocks design with three replications. the first factor was the source and amount of organic fertilizer (far...

This paper investigates the shear strength of municipal solid waste (MSW) using the back analysis of failed waste slopes as well as field and laboratory test results. Shear strength of MSW is a function of many factors such as waste type, composition, compaction, daily cover, moisture conditions, age, decomposition, overburden pressure, etc. These factors together with non-standardized sampling...

A declining trend in per hectare yield of sugarcane Wonji-Shoa Sugar Estate is being observed due to altering soil physicochemical properties resulted from long term cultivation. Cognizant this fact, a study was conducted 2017at with the objective determining effects more than 62 years cultivation on soil. In order achieve disturbed and undisturbed samples were collected 0-30 30-60 cm layers se...

Soil compaction has been recognised as the greatest problem in terms of damage to Australia's soil resource. Compaction by tractor and harvester tyres, related to traf®cking of wet soil, is one source of the problem. In this paper an array of soil properties was measured before and immediately after the application of a known compaction force to a wet Vertisol. A local grain harvester was used ...
