Database cracking has been an area of active research in recent years. The core idea of database cracking is to create indexes adaptively and incrementally as a side-product of query processing. Several works have proposed different cracking techniques for different aspects including updates, tuple-reconstruction, convergence, concurrency-control, and robustness. However, there is a lack of any...

Lining systems render a significant role in ensuring that waste materials are safely separated from the environment. Despite the advent of modern lining systems, compacted clay barriers or liners are regarded as one of the very significant components of lining system and are being used as a waste containment system in landfills which require insignificant infiltration. Compacted clay barriers m...

introduction: pomegranate (punica granatum l.) belong to punicaceae family is native to iran and grown extensively in arid and semi-arid regions worldwide. pomegranate is also important in human medicine and its components have a wide range of clinical applications. cracking causes a major fruit loss, which is a serious commercial loss to farmers. fruit cracking, seems to be a problem that less...

The water budget in clay shale terrain is controlled by a complex interaction between the vertisol soil layer, the underlying fractured rock, land use, topography, and seasonal trends in rainfall and evapotranspiration. Rainfall, runoff, lateral flow, soil moisture, and groundwater levels were monitored over an annual recharge cycle. Four phases of soil–aquifer response were noted over the stud...

In Bhopal, the widespread occurrences of cracking due to alternate swelling and shrinking in lightly loaded structures provided with traditional foundation like the strip footings in are covered by swelling soil. It is likely that foundation movements, due to shrinkage and swelling of expansive soil as a result of moisture content changes are responsible for more damage to building than any oth...

Mechanisms of shrinkage and the conditions leading to cracking of drying soils are addressed. An elastic formulation of the hydro-mechanical drying problem is presented. It relies on the analogy which can be drawn between the desiccation process and thermo-elasticity. The validity of the analogy is discussed in the light of finite element simulations of air drying experiments on a rectangular s...

Experimental results for the cracking of heterogeneous clay samples during desiccation are reported, and an associated numerical model is developed comparison. The contain embedded rigid inclusions to induce strain fields drying. crack paths local monitored process using digital image correlation. A phase field initiation propagation introduced compared with experimental results. qualitative ag...
