In this paper we consider the well-known BPX-preconditioner in conjunction with adaptive FEM. We present an algorithm which enables us to compute the preconditioner with optimal complexity by a total of only O(DoF) additional memory.

Numerical examples illustrate the efficiency of the algorithms.

A new combination of techniques for the numerical computation of incompressible flow is presented. The temporal discretization bases on the discontinuous Galerkin-formulation. Both constant (DG(0)) and linear approximation (DG(1)) in time is discussed. In case of DG(1) an iterative method reduces the problem to a sequence of problems each with the dimension of the DG(0) approach. For the semi-discrete problems a Galerkin/least-squares method is applied. Furthermore a non-overlapping domain decomposition method can be used for a parallelized computation.

Abstract:
People with autism spectrum disorder (ASD) and intellectual disability (ID) suffer from chronic diseases and conditions as in the general population but are more likely to have physical and psychological comorbidities. Health problems and pain can go totally unrecognized and untreated. This places them at higher risk for experiencing pain and having more frequent or severe pain. Self-report is the gold standard in pain assessment, but people with ASD and ID often cannot provide self-reports. Pain assessment in this population is therefore challenging. Furthermore, caregivers need to be knowledgeable about alternative pain assessment methods. Until recently, persons with ASD and ID were considered insensitive to pain. The specifics of autistic functioning include sensory perceptive association, which, associated with cognitive impairment and difficulties in communication, question the real nature of the relationship between pain and people with ASD. Some data from the literature highlight that people with ASD are pain hypersensitive and that the pain expression is abnormal. New research in ASD establishing a link between behavior disorders and pain should allow us to change the way we identify, assess, and treat pain and some behavioral problems. From these elements, a specific clinical approach and assessment of pain can be promoted.

Abstract:
Ontology alignment is recognized as a fundamental process to achieve an adequate interoperability between people or systems that use different, overlapping ontologies to represent common knowledge. This process consists of finding the semantic relations between different ontologies. There are different techniques conceived to measure the semantic similarity of elements from separate ontologies, which must be adequately combined in order to obtain precise and complete results. Nevertheless, combining multiple measures into a single similarity metric is a complex problem, which has been traditionally solved using weights determined manually by an expert, or calculated through general methods that does not provide optimal results. In this chapter, a genetic algorithm based approach to find out how to aggregate different similarity metrics into a single measure is presented. Starting from an initial population of individuals, each one representing a specific combination of measures, the algorithm finds the combination that provides the best alignment quality.

Full text
Abstract:
The chapter deals with the assessment of the seismic vulnerability of the “San Francesco ad Alto” historical masonry building, a former church located in Ancona (Italy), which is currently used as a Regional Headquarter of the Marche Region by the Italian Army. The interest toward this building comes from a double motivation. From the one side, it underwent a series of structural changes, including the addition of a new floor splitting in two levels the original nave, which makes the structure very peculiar and closer to a classical building than to a church. From the other side, it is no longer used as a church, a fact that changes the hazard aspects. The construction schematically consists of two masonry boxes overlapping, the lower being wider than the upper. It has various characteristic structural elements, such as some semicircular arches, segmental arches, timber floors, a barrel vault, some wooden trusses on the roof and steel ties in retention of the facade and of the external walls. The equivalent frame method is used, and several pushover analyses are performed. The seismic action has been defined considering the building both with strategic (current situation) and with ordinary (possible future situation) importance during earthquakes. The role of the masonry spandrels on the response of the structure has been investigated in depth and the main effects highlighted. The result of the pushover analyses is a seismic risk index (IR), that defines the safety level of the construction with respect to one ultimate limit state (SLU), in particular the so-called limit state of “saving life” (SLV).

The methodology required to achieve the data communication between the sub-grids and the base grid is adapted from multi-grid methods. This is a ‘Global-Local’ style approach in which a multi-grid style iterative correction is applied followi

Laser shock peening is a surface treatment technique similar to conventional shot peening. The laser induced plasma causes plastic deformations and compressive residual stresses in materials which are useful for developing improved properties in the fields of fatigue, wear or stress corrosion cracking. Finite element method is an efficient tool to predict the mechanical effects and the deformations caused due to laser shock peening, which otherwise are difficult to calculate due to the severe pressure imparted in a very short period of time.
