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 [...]

AgriPrediction: A proactive internet of things model to anticipate problems and improve production in agricultural crops

One of the significant challenges for the future is to guarantee food for all inhabitants of the planet. One of the alternatives for this issue consists in increasing the production, but to accomplish this, it is necessary that innovative options be applied to enhance the soil capacity and the protection of environmental resources. In this [...]

Internet of Health Things: Toward intelligent vital signs monitoring in hospital wards

BACKGROUND: Large amounts of patient data are routinely manually collected in hospitals by using standalone medical devices, including vital signs. Such data is sometimes stored in spreadsheets, not forming part of patients' electronic health records, and is therefore difficult for caregivers to combine and analyze. One possible solution to overcome these limitations is the interconnection [...]

A Última Década do Uso de Internet das Coisas Durante a Triagem de Pacientes no Departamento de Emergência – Um Mapeamento Sistemático

This article presents a systematic mapping of the literature on patient triage in the emergency department of hospitals using the smart devices of the Internet of Things. Method: For this, 533 articles were found in several sources of research; Where, after applying exclusion criteria, there were 16 articles were further analyzed. Result: We identified that [...]

A Mapping Study on Mobile Games for Patients of Chronic Diseases

There is a growing interest of using technologies to propose solutions for healthcare issues. One of such issues is the incidence of chronic diseases, which are responsible for a considerable proportion of worldwide mortality. It is possible to prevent the development of such diseases using tools and methods that instruct the population. To achieve this, [...]

MMEliot: Um Modelo para Internet das Coisas Explorando a Elasticidade da Computação em Nuvem

Atualmente, a adoção de tecnologias relacionadas à Internet das Coisas vem aumentando gradativamente. Devido a isso, cada vez mais são exigidas altas demandas de computação para tratar volumes grandes de dados. Como solução, a Computação em Nuvem se mostra promissora para suprir tais necessidades. Neste contexto, este artigo apresenta um modelo de elasticidade em nuvem [...]

Observing Network Performance and Congestion on Managing Assets with RFID and Cloud Computing

Today, we observe that more and more, radio frequency identification (RFID) technology has been used to identify and track objects in enterprises and institutions. In addition, we also perceive the growing adoption of cloud computing, either public or private, to process and store data from the objects. In this context, the literature does not present [...]

Towards Enabling Live Thresholding as Utility to Manage Elastic Master-Slave Applications in the Cloud

The elasticity feature of cloud computing has been proved as pertinent for parallel applications, since users do not need to take care about the best choice for the number of processes/resources beforehand. To accomplish this, the most common approaches use threshold-based reactive elasticity or time-consuming proactive elasticity. However, both present at least one problem related [...]

ElCity: an Elastic Multilevel Energy Saving Model for Smart Cities

As a result of rural and suburban migration to the cities, urban life has become a significant challenge for citizens and, particularly, for city administrators who must manage the sustainable use of resources such as energy, water, and transportation. Smart cities are the biggest vision to efficiently address these challenges through a real-time monitoring, providing [...]

GTTracker: Location-aware hierarchical model for identifying M-commerce business opportunities

he increased adoption of electronic commerce for selling products and services creates a new channel between consumers and vendors. Commonly, e-commerce platforms are assembled as proprietary and centralized solutions. This method has a high financial cost and slows the entry of both middle and small-sized companies into this communication channel. In this context, this article [...]
