Economic analysis of productivity in the Irish Construction sector

Important strides to enhance productivity in the construction sector have been taken by both industry and Government in recent years. However, a collaborative, sectoral wide strategy to drive further increases in productivity is required, with the coordinated participation of all stakeholders across the full life cycle of a project. This report, commissioned by the Department of Public Expenditure and Reform (DPER), produced by KPMG and Future Analytics Consulting Ltd. (FAC) and peer reviewed by TU Dublin, aims to understand and address the reasons for low levels of productivity in the Irish construction sector and identify specific recommendations and actions that can be undertaken to address these issues. All research was undertaken in 2019

QR Factorization of Tall and Skinny Matrices in a Grid Computing Environment

Previous studies have reported that common dense linear algebra operations do not achieve speed up by using multiple geographical sites of a computational grid. Because such operations are the building blocks of most scientific applications, conventional supercomputers are still strongly predominant in high-performance computing and the use of grids for speeding up large-scale scientific problems is limited to applications exhibiting parallelism at a higher level. We have identified two performance bottlenecks in the distributed memory algorithms implemented in ScaLAPACK, a state-of-the-art dense linear algebra library. First, because ScaLAPACK assumes a homogeneous communication network, the implementations of ScaLAPACK algorithms lack locality in their communication pattern. Second, the number of messages sent in the ScaLAPACK algorithms is significantly greater than other algorithms that trade flops for communication. In this paper, we present a new approach for computing a QR factorization -- one of the main dense linear algebra kernels -- of tall and skinny matrices in a grid computing environment that overcomes these two bottlenecks. Our contribution is to articulate a recently proposed algorithm (Communication Avoiding QR) with a topology-aware middleware (QCG-OMPI) in order to confine intensive communications (ScaLAPACK calls) within the different geographical sites. An experimental study conducted on the Grid'5000 platform shows that the resulting performance increases linearly with the number of geographical sites on large-scale problems (and is in particular consistently higher than ScaLAPACK's).Comment: Accepted at IPDPS10.

A radiografia de tórax de uma criança com asma

Aula 8 do Curso Capacitação a Distância em Asma na Infância e Adolescência. O diagnóstico de asma na infância é essencialmente clínico, porém devido a possibilidade de outros diagnósticos diferenciais de sibilância na infância, torna-se fundamental o estudo por imagem do tórax de uma criança com esta suspeita clínica. A radiografia de tórax deve ser realizada para confirmação do diagnóstico de asma quando o padrão da crise se agrava, como também para monitorização do tratamento durante a internação hospitalar. A tomografia computadorizada do tórax por representar uma dose de radiação muito maior para a criança, tem indicações limitadas e deve ser solicitada de forma muito criteriosa.Apresentação de radiografia de tórax para demostrar a anatomia radiológica do tórax , os sinais radiográficos de asma e suas complicações, os possíveis diagnósticos diferencias e as principais indicações da tomografia de tórax.1.
