Denoising diffusion probabilistic models (DDPMs) have demonstrated significant potential in addressing complex image processing challenges. This paper explores the application of DDPMs in three different areas: reconstruction of remote sensing imagery affected by cloud cover, reconstruction of facial images with occluded areas, and segmentation of bodies of water from remote sensing imagery. Inpainting involves filling in missing regions in images, while DDPMs act as data generators capable of synthesizing information that alings coherently with the context of the original data. Inspired by the inpainting technique, the RePaint approach was adapted and applied to reconstruction tasks. The WaterSegDiff approach, which uses a diffusion model as a backbone, was employed for the segmentation task. To illustrate the model’s behavior and provide examples of the tasks, experiments were carrie...

The wide adoption of Laser Powder Bed Fusion (LPBF) in additive manufacturing has led to the need for a comprehensive understanding of the corrosion behavior of LPBF-fabricated components [1]. This thesis focuses on the pitting corrosion behavior of 316L stainless steel, emphasizing the influence of process-induced porosity. The impact of various defects on pitting corrosion behavior was explored through a series of experimental investigations using cyclic potentiodynamic polarization in a 0.6M NaCl solution. The study revealed that LPBF 316L SS exhibited superior pitting resistance compared to its wrought counterpart [2]–[7], even in the presence of manufacturing defects. Interestingly, despite their larger size and open porosity, gas voids were not the preferred sites for pitting propagation. The presence of these voids did not accelerate the accumulation of metal cations, thus dimin...

Thermodynamic simulation models have been developed to observe the behavior of the minor elements Zn, Pb, As, Sb and Bi; as well as the major elements Cu, Fe, Si, 0 and S in the conversion and fusion processes: NORANDA and ISASMELT for the production of copper-rich mattes. The Noranda process shows a steady state model for obtaining a high-grade matte in metallic copper. The lsasmelt process is based on the concept of the two independent reaction sites in the bath (slag-killing interface): rapid oxidation and slow reduction. The heat balance of the process and the distribution thermodynamics of the minor elements are united and expressed in terms of the process variables such as temperature, enriched 02, composition of the charge, degree of matte and content of the magnetite in the Slag and other variables are incorporated into the modeling, which can predict the operating effects of che...

An educational Virtual Lab, a software oriented to teaching and learning, applied to the study of the Thresholded Difference of grey-leveled images has been developed. This intuitively-easy-to-use Virtual Lab allows studying the threshold-controlled difference of two input images. Interesting results emerge when detecting the thresholded difference of pairs of images, like the effect appearing in the case of image subtraction of two completely different images, an effect setting up the basis for Controlled Image Fusion. Image difference algorithms belong to Digital Image Processing, a computer tool with every time more applications in science and in engineering.

Purpose. The purpose of this article is to propose a detailed methodology to estimate, model and incorporate the non-constant volatility onto a numerical tree scheme, to evaluate a real option, using a quadrinomial multiplicative recombination. Design/methodology/approach. This article uses the multiplicative quadrinomial tree numerical method with non-constant volatility, based on stochastic differential equations of the GARCH-diffusion type to value real options when the volatility is stochastic. Findings. Findings showed that in the proposed method with volatility tends to zero, the multiplicative binomial traditional method is a particular case, and results are comparable between these methodologies, as well as to the exact solution offered by the Black–Scholes model. Originality/value. The originality of this paper lies in try to model the implicit (conditional) market volatility ...
