A lightweight plug-and-play elasticity service for self-organizing resource provisioning on parallel applications

Today cloud elasticity can bring benefits to parallel applications, besides the traditional targets including Web and critical-business demands. This consists in adapting the number of resources and processes at runtime, so users do not need to worry about the best choice for them beforehand. To accomplish this, the most common approaches use threshold-based reactive elasticity [...]

Spontaneous Social Network: toward dynamic virtual communities based on context-aware computing

Recent efforts regarding mobile social networks aim at connecting people in smart environments considering not only their social behavior but also their context. In this perspective, this work presents a model, named SSN, based on the concept of Spontaneous Social Network, which allows the interaction of people anywhere and anytime without the need of any [...]

Geometry accuracy of DSM in water body margin obtained from an RGB camera with NIR band and a multispectral sensor embedded in UAV

The photogrammetry techniques are known to be accessible due to its low cost, while the geometric accuracy is a key point to ensure that models obtained from photogrammetry are a feasible solution. This work evaluated the discrepancies in 3D (DSM) and 2D (orthomosaic) models obtained from photogrammetry using control points (GCPs) near a reflective/refractive area [...]

A new relationship between the quality criteria for geodetic networks

The goal of this paper is to present a new relationship between the quality criteria for geodetic networks. The quality criteria described here are fourfold: positional uncertainty of network points, considering both bias and precision (at a given confidence level); the maximum allowable number of undetected outliers; the level of reliability and its homogeneity for [...]

A Survey of Sensors in Healthcare Workflow Monitoring

Activities of a clinical staff in healthcare environments must regularly be adapted to new treatment methods, medications, and technologies. This constant evolution requires the monitoring of the workflow, or the sequence of actions from actors involved in a procedure, to ensure quality of medical services. In this context, recent advances in sensing technologies, including Real-time [...]

Análise gráfica das variáveis do controle de qualidade de dados geodésicos por meio de testes estatísticos

Na Geodésia, o controle de qualidade (CQ) é uma das etapas de maior importância, onde é decidido se os resultados obtidos serão validados ou não. Dentro desse contexto, os testes estatísticos ainda são as ferramentas mais utilizadas para detecção e identificação de outliers (erros não aleatórios), dentre eles o famoso Data Snooping proposto por Baarda. [...]

MigPF: Towards on self-organizing process rescheduling of Bulk-Synchronous Parallel applications

Migration is a known technique to offer process rescheduling, being especially pertinent for Bulk Synchronous Parallel (BSP) programs. Such programs are organized in a set of supersteps, in which the slowest process always determines the synchronization time. This approach motivated us to develop a first model called MigBSP, which combines computation, communication, and migration costs metrics [...]

High-resolution spectroscopy for detecting stratigraphic surfaces and stacking patterns in sedimentary basins

In this research was evaluated the potential of using scores derived from spectral data to detect surfaces and stacking patterns in the sedimentary record, and propose a new method for analyzing spectral data. Spectral field surveys with wavelengths ranging between 2.0 and 2.5 μm were acquired from three well-exposed outcrops in the Neuquén Basin, Argentina. The [...]

Spatial analyzes of HLA data in Rio Grande do Sul, south Brazil: genetic structure and possible correlation with autoimmune diseases

Background HLA genes are the most polymorphic of the human genome and have distinct allelic frequencies in populations of different geographical regions of the world, serving as genetic markers in ancestry studies. In addition, specific HLA alleles may be associated with various autoimmune and infectious diseases. The bone marrow donor registry in Brazil is the [...]

Análise bibliográfica sobre as potencialidades da aquisição de imagens multi e hiperespectrais por VANTs no auxílio à inspeção de obras de arte especiais

As Obras de Arte Especiais (OAEs) surgiram com o intuito de facilitar a mobilidade urbana. Logo, é fundamental a realização de inspeções periódicas e manutenções preventivas, a fim de identificar possíveis manifestações patológicas. Atualmente as técnicas empregadas são baseadas na inspeção visual, na qual a principal dificuldade é a acessibilidade a todos os locais da [...]
