We have developed a hyperbolic penalty function for image estimation. The center of a hyperbola is parabolic like that of an l2 norm fitting. Its asymptotes are similar to l1 norm fitting. A transition threshold must be chosen for regression equations of data fitting and another threshold for model regularization. We combined two methods: Newton’s and a variant of conjugate gradient method to s...

The effect of deformation temperature on the mechanical properties 1-GPa-grade TRIP steels with different retained austenite (?R) morphologies was studied. dependence deformation-induced martensitic transformation behavior also investigated. uniform elongation below room relatively large in needle-like ?R steel, whereas tensile strength at each almost same as it independent morphology. better s...

This paper aims to test, in a quantitative way, the different approaches that can be applied improve contact resistance problem debris environment for acquisition of electrical resistivity tomography. We collected various datasets on same investigation line blocky ground surface landslide deposit, using coupling systems: single electrodes placed between boulders, adding extra parallel and drill...

While the characteristics and origin of drusy calcite cement in carbonate deposits is well constrained literature, little attention paid to dolomite cement. Petrographic observations, stable isotopes, fluid-inclusion microthermometry suggest that Permo-Triassic conglomerate/breccia dolostone beds northern United Arab Emirates has precipitated as not by dolomitization The low ?18OVPDB (?9.4‰ ?6....

Abstract We present a three-dimensional (3D) general-measure inversion scheme of crosswell electromagnetic (EM) data in the frequency domain with direct forward solver. In problem, we discretised EM Helmholtz equation by staggered-grid finite difference (SGFD) and solved it using Intel MKL PARDISO By applying solver, simultaneously multisource problems at given frequency. inversion, integrated ...

Retained austenite (RA) transformation and its role in the mechanical properties of three low-carbon micro-alloyed quenching partitioning (Q&P) steels was investigated utilizing situ tensile tests electron microscopy. Meanwhile, RA’s strain-induced martensite (SIMT) analyzed discussed terms strengthening mechanism. The results show that ductility Q&P relies on size morphology RA. In add...

The shear strength of intermittent joints in rock masses is significantly influenced by the stability blocky system. connection rate for a single joint crucial mechanical properties, such as strength. To examine impact connectivity on structural and fracture evolution joints, direct test conducted artificial coplanar with various rates under numerous different normal stresses. In this paper, nu...

The aim of this study is to determine the types soil in Ranya district and analyze its physical characteristics terms texture structure suitability for planting wheat barley. Research on great importance agriculture, so from perspective we can capacity produce crops. During our research, were able take 39 samples area, which are divided into according Buring classification using Geographic Info...

Synthesis of one-dimensional nanofibers with distinct topological (higher-order structural) domains in the same main chain is one challenging topics modern supramolecular polymer chemistry. Non-uniform structural transformation chains by external stimuli may enable preparation such nanofibers. To demonstrate feasibility this post-polymerization strategy, we prepared a photoresponsive helically ...

Among Australasian tektites, the so-called Muong Nong tektites stand out for their peculiar layering and blocky aspect. Although source crater is not known, are generally considered as a relatively proximal ejecta. The mechanism responsible formation of has been matter debate. In this work, we revisit paleomagnetism tektites. They retain thermoremanent magnetization acquired during cooling belo...
