Abstract Specialists of Dnipro University Technology are among the leading researchers involved in studying specifics implementation and functioning rational energy-efficient schemes organization circulation processes while well drilling operating. In particular, we have carried out thorough comprehensive studies physicochemical phenomena used creating, preparing, using washing fluids. The purp...

We propose a new mesh refinement algorithm for computing quality guaranteed Delaunay triangulations in three dimensions. The refinement relies on new ideas for computing the goodness of the mesh, and a sampling strategy that employs numerically stable Steiner points. We show through experiments that the new algorithm results in sparse well-spaced point sets which in turn leads to tetrahedral me...

Does local context (e.g., city of residence) matter for self and well-being? We theorized that it does because local contexts diverge in prevalent historically-derived ideas, norms, and products. Through historical analysis, studies of norms (tightness-looseness; Study 1) and cultural products (content analyses of newspaper headlines, venture capital firm websites, hospital websites; Studies 2-...

The goal of this paper is to generalize the well-balanced approach for non-equilibrium flow studied by Wang et al. (2009) [29] to a class of low dissipative high-order shock-capturing filter schemes and to explore more advantages of well-balanced schemes in reacting flows. More general 1D and 2D reacting flow models and new examples of shock turbulence interactions are provided to demonstrate t...

Construction of geothermal wells that are effectively cemented and durable poses a significant operational challenge. Typically, lost circulation while drilling and cementing can make it seemingly impossible to place a complete column of cement behind casing strings. Incomplete cementation can lead to well failure caused by cyclic temperature loading on the casing that occurs throughout the lif...

JEL classification: R21 R31 Construction quality is a major problem in China's housing market. We investigate whether the housing market could provide incentives to encourage developers to promote construction quality beyond the compulsory, minimum standards by testing the financial viability of efforts made in this field by developers. This study takes place in the city of Beijing, where the “...

We present a fully automatic approach to construct a large-scale, highprecision dataset from noisy web images. Within the entire pipeline, we focus on generating high quality seed images for subsequent dataset growing. High quality seeds are essential as we revealed, but they have received relatively less attention in previous works with respect to how to automatically generate them. In this wo...

Recently a few systems for automatically solving math word problems have reported promising results. However, the datasets used for evaluation have limitations in both scale and diversity. In this paper, we build a large-scale dataset which is more than 9 times the size of previous ones, and contains many more problem types. Problems in the dataset are semiautomatically obtained from community ...

Site-saturation mutagenesis is a powerful tool for protein optimization due to its efficiency and simplicity. A degenerate codon NNN or NNS (K) is often used to encode the 20 standard amino acids, but this will produce redundant codons and cause uneven distribution of amino acids in the constructed library. Here we present a novel "small-intelligent" strategy to construct mutagenesis libraries ...
