BLE-Based Indoor Localization: Analysis of Some Solutions for Performance Improvement.

This paper addresses indoor localization using an anchor-based system based on Bluetooth Low Energy (BLE) 5.0 technology, adopting the Received Signal Strength Indicator (RSSI) for the distance estimation. Different solutions have been proposed in the scientific literature to improve the performance of this localization technology, but a detailed performance comparison of these solutions is still missing.

Discussion on Secure Standard Network of Sensors Powered by Microbial Fuel Cells.

Everyday tasks use sensors to monitor and provide information about processes in different scenarios, such as monitoring devices in manufacturing or homes. Sensors need to communicate, with or without wires, while providing secure information. Power can be derived from various energy sources, such as batteries, electrical power grids, and energy harvesting.

An Interoperable Digital Twin with the IEEE 1451 Standards.

The shop floor or factory floor is the area inside a factory where manufacturing production is executed. The digitalisation of this area has been increasing in the last few years, introducing the Digital Twin (DT) and the Industry 4.0 concepts.

Integrating the IEEE 1451 and IEC 61499 Standards with the Industrial Internet Reference Architecture.

Industrial Internet of Things focuses on the manufacturing process and connects with other associated concepts such as Industry 4.0, Cyber-Physical Systems, and Cyber-Physical Production Systems. Because of the complexity of those components, it is necessary to define reference architectures models to manage Industry 4.

An intelligent sensor array distributed system for vibration analysis and acoustic noise characterization of a linear switched reluctance actuator.

This paper proposes a distributed system for analysis and monitoring (DSAM) of vibrations and acoustic noise, which consists of an array of intelligent modules, sensor modules, communication bus and a host PC acting as data center. The main advantages of the DSAM are its modularity, scalability, and flexibility for use of different type of sensors/transducers, with analog or digital outputs, and for signals of different nature. Its final cost is also significantly lower than other available commercial solutions.

[Municipal public health spending in the state of Pernambuco, Brazil, from 2000 to 2007].

In order to assess the impact of macro-political measures implemented in the latter half of the 1990s on the increase in public spending on health and the possible reduction in allocation inequity, a descriptive, quantitative, cross-sectional study was carried out involving 184 municipalities in the state of Pernambuco, Brazil. Data from the Public Health Budget Information System was used, with the selected indicator being spending on health per inhabitant under the responsibility of the municipality. The correlations of this variable with the municipal Human Development Index, population size and value of the municipal budget per capita were analyzed.

[Reliability of data on compliance with Constitutional Amendment 29 reported to the Public Healthcare Budget Information System by municipalities in Pernambuco State, Brazil].

The present study analyzes the reliability of data on compliance with Constitutional Amendment 29 (CA29) reported to the Public Healthcare Budget Information System (known as SIOPS) by municipalities in the State of Pernambuco, Brazil. A quantitative, analytical cross-sectional study was conducted using the years 2000 to 2005 as the reference. Invoices audited by the State Accounts Court were used as the parameter for determining reliability of the percentage of compliance with CA29 as reported to SIOPS, using the intraclass correlation coefficient (ICC) to measure data agreement.

[Prevalence of obesity and associated factors in elderly women].

Objective: To analyze the prevalence of obesity in elderly women and its association with socio-demographic, biochemical and hypertension variables.

Material And Methods: By means of a cross sectional study, 188 outpatient women, 60 to 89 years-old were assessed. Obesity was defined by a BMI > 30 Kg/m2 (WHO, 1998).

[Conceptions and practices of community health agents caring for the elderly].

Objective: To assess the main conceptions related to the aging process among community health agents.

Methods: An exploratory descriptive qualitative study was carried out in Pernambuco, Northeastern Brazil, from 2000 to 2002. Data was collected from records and interviews with 148 community health agents.
