Many inverse problems involve two or more sets of variables that represent different physical quantities but are tightly coupled with each other. For example, image super-resolution requires joint estimation of image and motion parameters from noisy measurements. Exploiting this structure is key for efficiently solving large-scale problems to avoid, e.g., ill-conditioned optimization problems. ...

Tomatoes (Lycopersicon esculentum) express two forms of leucine aminopeptidase (LAP-A and LAP-N) and two LAP-like proteins. The relatedness of LAP-N and LAP-A was determined using affinity-purified antibodies to four LAP-A protein domains. Antibodies to epitopes in the most N-terminal region were able to discriminate between LAP-A and LAP-N, whereas antibodies recognizing central and COOH-termi...

Three-dimensional finite element models are developed to investigate the effects of both tensile load and uniform temperature load on the stresses in hybrid joints. During the solution of the problem, finite element method (FEM) is preferred, as this method is very suitable for solving many engineering problems. An aluminum sheet is bonded a composite sheet. Hybrid joints are designed from both...

The recent increase in the use of adhesively bonded joints (ABJs) made from dissimilar adherends demands acquisition a better understanding strength and behaviour these joints, including their failure mechanisms. Several studies have reported on such individually, however few compared performances ABJs with varying configurations design parameters, order to determine optimal configuration for h...

The aerospace, automotive and marine industries have witnessed a rapid increase of using adhesive bonded joints due to their advantages in joining dissimilar and/or new engineering materials. Joint strength is the key property evaluating capability joint. In this paper, developments black-box grey-box machine learning (ML) models are presented allow accurate predictions failure load single lap ...

This paper aims to study the mechanical behaviour and failure mode of Al 2024-T3 in double-lap bolted joints. To accomplish this, the effect of geometric parameters was investigated in both configurations of single and double fasteners. Using ABAQUS/Standard, a three-dimensional finite element model was developed and verified against the experimental results of the joints loaded in tension. In ...
