Let Σ be a compact Riemann surface. Any sequence fn : Σ —> M of harmonic maps with bounded energy has a "bubble tree limit" consisting of a harmonic map /o : Σ -> M and a tree of bubbles fk : S 2 -> M. We give a precise construction of this bubble tree and show that the limit preserves energy and homotopy class, and that the images of the fn converge pointwise. We then give explicit counterexam...

With many aromatic compounds in liquid solution, the population of the metastable triplet state T, leads to delayed Sn-+SO fluorescence ( DFn, n 3 1) of the pyrene type, which results from the generation of excited singlet states S, by nonradiative triplettriplet annihilation (TTA) T, +T, +,+$. Knox and Swenberg have postulated that, apart from the DFl, there should be an extremely weak direct ...

Abstract Stability assessment of potential wedge failures in rock slopes is usually carried out based on stereographic projection techniques and limit equilibrium analyses. Nevertheless, this methodology presents several limitations (i.e., lack information joint mechanical properties, oversimplification the structure, etc.) that could lead to poorly accurate conclusions. In line with idea, main...

Abstract Hydraulic fracturing is the key technology in development of shale gas reservoirs, and it mainly adopts volume to communicate hydraulic fractures with natural increase drainage area. In view difficulty characterizing complex created by multistaged horizontal wells immaturity optimization design methods, this study first evaluated stimulation effect based on treatment data microseismic ...

Despite the successful application of multimodal deep learning (MDL) methods for land use/land cover (LULC) classification tasks, their fusion capacity has not yet been substantially examined hyperspectral and synthetic aperture radar (SAR) data. Hyperspectral SAR data have recently widely used in classification. However, speckle noise heterogeneity with imaging mechanism hindered MDL integrati...

Numerous reservoirs that play a significant role in worldwide petroleum production and reserves contain fractures. Typically, the fractures must form connected network for reservoir to be classified as naturally fractured. Characterizing with focus on its fracture is crucial modeling predicting performance. To simplify solution, dual-continuum techniques are commonly employed. However, use cont...

With this research, the analysis and resolution have been developed through direct rigidity method of a structure with non-deformable rigid solid. The has carried out annually verified FTOOL software, in order to corroborate what done. For its execution we used our own procedures seen Structural Analysis II course at UNISCJSA, following being typical system: Determination Q-D System [Q], Primar...

We studied the formation and evolution mechanism of polygonal cracks on rock surfaces under cooling by modelling meso-damage mechanics, continuum mechanics thermodynamics. Factors that affect surface damage include ambient temperature, lithology difference boundary restrictions. established simulated a heterogeneous model with weak layer for three types boundaries. These were biaxial constraint...
