In Vitro Measurement of Strain Localization Preceding Dissection of the Aortic Wall Subjected to Radial Tension

2020

AbstractBackgroundAortic dissection (AD) is a common pathology and challenging clinical problem. A better understanding of the biomechanical effects preceding its initiation is essential for predicting adverse events on a patient-specific basis. Moreover, the predictability of patient-specific biomechanics-based computational models is hampered by uncertainty about boundary conditions and material properties.ObjectivePredisposition of thoracic aortic aneurysms (TAA) to ADs can be related to the degradation of biomechanically important constituents in the aortic wall of TAAs. The goal of the present study is to develop a new methodology to measure strain fields in aortic tissues subjected to…

3D displacement field measurement with correlation based on the micro-geometrical surface texture

2011

Image correlation methods are widely used in experimental mechanics to obtain displacement field measurements. Currently, these methods are applied using digital images of the initial and deformed surfaces sprayed with black or white paint. Speckle patterns are then captured and the correlation is performed with a high degree of accuracy to an order of 0.01 pixels. In 3D, however, stereo-correlation leads to a lower degree of accuracy. Correlation techniques are based on the search for a sub-image (or pattern) displacement field. The work presented in this paper introduces a new correlation-based approach for 3D displacement field measurement that uses an additional 3D laser scanner and a C…

Sociālo tīklu izmantošana pašvaldībās Latvijā.

2021

Mūsdienās iedzīvotāji informācijas iegūšanai arvien vairāk izmanto interneta resursus, īpaši sociālos tīklus, tāpēc svarīgs aspekts ir, cik lielu uzmanību pašvaldības pievērš sociālajiem tīkliem un to attīstībai. Bakalaura darba mērķis ir noskaidrot, kā pašvaldībās Latvijā tiek izmantoti sociālie tīkli, un izstrādāt priekšlikumus, kas būtu jāattīsta digitālā mārketinga jomā Latvijas pašvaldībās, lai tās veicinātu sabiedrības līdzdalību pašvaldību lēmumu pieņemšanā un uzlabotu komunikāciju ar iedzīvotājiem. Lai veiksmīgi sasniegtu darba mērķi, darbā analizēta pašreizējā pašvaldību sociālo tīklu izmantošana, kā arī veikta aptaujas ar pašvaldību pārstāvjiem un Latvijas pašvaldību sociālo tīklu…

Buckling analysis of multilayered structures using high-order theories and the implicit-mesh discontinuous Galerkin method

2022

This work presents a novel formulation for the linear buckling analysis of multilayered shells. The formulation employs high-order Equivalent-Single-Layer (ESL) shell theories based on the through-the-thickness expansion of the covariant components of the displacement field, whilst the corresponding buckling problem is derived using the Euler’s method. The novelty of the formulation regards the solution of the governing equations, which is obtained via implicit-mesh discontinuous Galerkin (DG) schemes. The DG method is a high-order accurate numerical technique based on a discontinuous representation of the solution among the mesh elements and on the use of suitably defined boundary integral…

Longest Motifs with a Functionally Equivalent Central Block

2004

International audience; This paper presents a generalization of the notion of longest repeats with a block of k don't care symbols introduced by [Crochemore et al., LATIN 2004] (for k fixed) to longest motifs composed of three parts: a first and last that parameterize match (that is, match via some symbol renaming, initially unknown), and a functionally equivalent central block. Such three-part motifs are called longest block motifs. Different types of functional equivalence, and thus of matching criteria for the central block are considered, which include as a subcase the one treated in [Crochemore et al., LATIN 2004] and extend to the case of regular expressions with no Kleene closure or …

Some integral type fixed point theorems in Non-Archimedean Menger PM-Spaces with common property (E.A) and application of functional equations in dyn…

2013

In this paper, we prove some integral type common fixed point theorems for weakly compatible mappings in Non-Archimedean Menger PM-spaces employing common property (E.A). Some examples are furnished which demonstrate the validity of our results. We extend our main result to four finite families of self-mappings employing the notion of pairwise commuting. Moreover, we give an application which supports the usability of our main theorem.
