Multi-agent systems (MAS) paradigm is a suitable approach to implement distributed manufacturing systems addressing the emergent requirements of flexibility, robustness and responsiveness. In such systems, the distributed agents have a local view of the system environment being the global data collection a complex and critical issue to provide the functionalities of the ISA-95 standard, such as dynamic scheduling, maintenance management and quality assurance. This paper describes the data collection mechanisms in a multiagent system that supports the global monitoring over the time and the trend analysis to perform self-adaptation and selfoptimization. The proposed approach was developed and tested in an industrial washing machines production line.

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); O uso de medidas do desvio Doppler para localizar um transmissor foi estudado e testado considerando o Sistema Brasileiro de Coleta de Dados Ambientais. Para melhorar a localização de plataformas de coleta de dados (PCDs), com os seus transmissores, alguns efeitos como a correção devido a ionosfera e atroposfera, foram considerados no trabalho de Celestino et al. (2007) usando dados simulados e algumas avaliações dos erros iniciais de uma única PCD. Este trabalho apresenta uma avaliação dos impactos sobre a localização geográfica, devido aos efeitos da ionosfera e da troposfera, entretanto usando duas PCDs meteorológicas e cobrindo um periodo mais longo de testes (um ano). Os efeitos, sazonal e dia-noite, também são analisados durante este periodo experimental. Os resultados das análises indicam que a correção dos efeitos da ionosfera e da troposfera pode, em media, reduzir os erros de localização a escala entre dez e cem metros para as condições de testes independente da localização da PCD que foi utilizada. Devido a complexidade da modelagem das fontes dos erros na localização de uma plataforma...

The Brazilian National Institute for Space Research (INPE) is operating the Brazilian Environmental Data Collection System that currently amounts to a user community of around 100 organizations and more than 700 data collection platforms installed in Brazil. This system uses the SCD-1, SCD-2, and CBERS-2 low Earth orbit satellites to accomplish the data collection services. The main system applications are hydrology, meteorology, oceanography, water quality, and others. One of the functionalities offered by this system is the geographic localization of the data collection platforms by using Doppler shifts and a batch estimator based on least-squares technique. There is a growing demand to improve the quality of the geographical location of data collection platforms for animal tracking. This work presents an evaluation of the ionospheric and tropospheric effects on the Brazilian Environmental Data Collection System transmitter geographic location. Some models of the ionosphere and troposphere are presented to simulate their impacts and to evaluate performance of the platform location algorithm. The results of the Doppler shift measurements, using the SCD-2 satellite and the data collection platform (DCP) located in Cuiabá town, are presented and discussed.

The use of the Doppler shift measurements to locate atransmitter has been studied and tested within the Brazilian Environmental Data Collection System. To improve the location of Data Collection Platforms (DCPs) with their transmitters, some effects such as corrections due to the ionosphere and the troposphere have been considered in aprevious work (Celestino et aI., 2007) using simulated data and some initial error evaluation for one existing DCP. This work presents an evaluation of the impacts on the geographical location due to the ionospheric and the tropospheric effects, however using two meteorological DCPs and covering a longer test period (one year). The seasonal and day-night effects are also analyzed during this test period. The results of the analysis indicated that correction of the ionospheric and tropospheric effects can, on the average, reduce the location errors to the scale between ten and hundred meters for the test conditions independent of the DCP location that was used. Due to the complexity of modeling sources of errors in the location of a platform, still a considerable work need to be done to reduce location errors in the system. Initial analysis indicates that the knowledge of the satellite position can be another significant source of platform position error.

The proliferation of mobile phones in developing countries has generated a wave of interest in collecting high-frequency socioeconomic surveys using this technology. This paper considers lessons from one such survey effort in a difficult environment -- the South Sudan Experimental Phone Survey, which gathered data on living conditions, access to services, and citizen attitudes via monthly interviews by phones provided to respondents. Non-response, particularly in later rounds of the survey, was a substantial problem, largely due to erratic functioning of the mobile network. However, selection due to non-response does not appear to have markedly affected survey results. Response rates were much higher for respondents who owned their own phones. Both compensation provided to respondents in the form of airtime and the type of phone (solar-charged or traditional) were varied experimentally. The type of phone was uncorrelated with response rates and, contrary to expectation, attrition was slightly higher for those receiving the higher level of compensation. The South Sudan Experimental Phone Survey experience suggests that mobile phones can be a viable means of data collection for some purposes...

This paper surveys technological changes that affect the collection, organization, analysis and presentation of data. It considers changes or improvements that ought to influence the research process and direct the use of technology. It explores implications for graduate research training. The insights of Evidence-Based Medicine are widely relevant across many different research areas. Its insights provide a helpful context within which to discuss the use of technological change to improve the research process. Systematic data-based overview has to date received inadequate attention, both in research and in research training. Sharing of research data once results are published would both assist systematic overview and allow further scrutiny where published analyses seem deficient. Deficiencies in data collection and published data analysis are surprisingly common. Technologies that offer new perspectives on data collection and analysis include data warehousing, data mining, new approaches to data visualization and a variety of computing technologies that are in the tradition of knowledge engineering and machine learning. There is a large overlap of interest with statistics. Statistics is itself changing dramatically as a result of the interplay between theoretical development and the power of new computational tools. I comment briefly on other developing mathematical science application areas - notably molecular biology. The internet offers new possibilities for cooperation across institutional boundaries...

Abstract publicado em: Eur J Public Health. 2015; 25(Suppl 3): 398. doi:10.1093/eurpub/ckv176.069. Disponível em: http://eurpub.oxfordjournals.org/content/eurpub/25/suppl_3/ckv176.069.full.pdf; This work addresses practices related to quality assurance in the first Portuguese National Health Examination Survey (INSEF). INSEF is a cross-sectional population-based study that combines face-to-face interview, physical examination and blood collection and aims to obtain data on 4200 participants from all 7 regions of Portugal. To ensure accurate and high quality data, a monitoring system was implemented as part of internal quality assessment. It includes participant recruitment, physical examination, blood collection and interview and consists of: daily check of recruitment and participation; monitoring of blood pressure and anthropometric measurements by interviewer and collection site; monitoring blood draw, sample haemolyses and laboratory processing; evaluation of average time spent on each survey component by interviewer; daily validation of collected interview data to verify completeness and identify duplicates; regular contact with fieldwork teams to clarify issues raised in questionnaire administration. For each region we carried out survey quality assessment at the end of the second week of fieldwork (N=230 participants). Regional meetings took place to discuss assessment results and propose recommendations for improvement. Monitoring allowed identifying items in higher risk of missing data and challenging issues such as employing exclusion criteria. Proper registry of measurements and time spent were difficult for 3 out of 6 interviewers. We observed junior laboratory technicians to have higher rates of haemolysed samples...

Approved for public release; distribution is unlimited; In the field of human research, particularly in operational environments, data collection techniques are difficult. Researchers often focus their efforts on the data analysis and overlook the shortcomings of their data collection and storage methodologies. In order to demonstrate effective data collection and storage methodology in a representative human research process, the process used by human fatigue and performance researchers at the Human Systems Integration Lab at Naval Postgraduate School (NPS) served as a Proof of Concept. Most recent studies conducted at NPS provided a model of the current process. The Knowledge Value Added (KVA) methodology was used as a tool of comparison of the current process to the reengineered process. Information technologies including wireless physiological monitoring devices, web-based and mobile device data collection methods, and integrated data storage techniques were incorporated in the reengineering effort. The data storage process included the design of a standard relational database format allowing research teams to easily access their data. This repository also enables data to be archived for future use (e.g., meta-analyses). To demonstrate the reengineered process in an operational environment...

Recently, there has been increased attention to data use in the international public health community. At the global level there have been major investments in data collection for public health programs. However, there is concern that such data are not being used. Data and information lack value unless they are used to inform decisions. Interventions that increase local demand for information and facilitate its use enhance evidence-based decision making. Data use therefore, is critical to improving the effectiveness and sustainability of the health system. Data quality is poor and use of available data is low in India's health sector. The current study focuses on issues of data use. It aims to shed light on how data are used for decision-making at different levels of the health sector in India and to highlight impediments to improved data utilization. This report is organized in five sections. The survey design, instruments and the data collection process will be described in the next section. Findings including measurement of data use...

As mobile phone ownership rates have risen dramatically in Africa, there has been increased interest in using mobile telephones as a data collection platform. This note draws on two largely successful pilot projects in Tanzania and South Sudan that used mobile phones for high-frequency data collection. Data were collected on a wide range of topics and in a manner that was cost-effective, flexible, and rapid. Once households were included in the survey, they tended to stick with it: respondent fatigue has not been a major issue. While attrition and nonresponse have been challenges in the Tanzania survey, these were due to design flaws in that particular survey, challenges that can be avoided in future similar projects. Ensuring use of the data to demand better service delivery and policy decisions turned out to be as challenging as collecting the high-quality data. Experiences in Tanzania suggest that good data can be translated into public accountability, but also demonstrate that just putting data out in the public domain is not enough. This note discusses lessons learned and offers suggestions for future applications of mobile phone surveys in developing countries...

Different types of data are required for managing the road infrastructure. Inventory data describe the physical elements of a road system. Condition data describe the condition of elements that can be expected to change over time. There are a wide range of technologies available to the road manager for measuring attributes of the road network. The challenge is to select the appropriate equipment, given local conditions and the way in which the data are expected to be used. The purpose of this note is to give a general view of the currently available survey technologies applied to pavements, bridges and traffic. This includes an assessment of the applicability of these technologies in developing countries. The goal is to assist managers in establishing an appropriate and sustainable e data collection program and procuring the appropriate equipment to collect the data. This note is a summary of the report 'Data Collection Technologies for Road Management' (see report no. 37372). The note opens with a discussion of data collection requirements. This is then followed by separate discussions on pavements...

Objectives : The purpose of this article is to find out differences between surveys using paper and online questionnaires. The author has deep knowledge in the case of questions concerning opinions in the development of survey based research, e.g. the limits of postal and online questionnaires. Methods : In the physician studies carried out in 1995 (doctors graduated in 1982-1991), 2000 (doctors graduated in 1982-1996), 2005 (doctors graduated in 1982-2001), 2011 (doctors graduated in 1977-2006) and 457 family doctors in 2000, were used paper and online questionnaires. The response rates were 64%, 68%, 64%, 49% and 73%, respectively. Results : The results of the physician studies showed that there were differences between methods. These differences were connected with using paper-based questionnaire and online questionnaire and response rate. The online-based survey gave a lower response rate than the postal survey. The major advantages of online survey were short response time; very low financial resource needs and data were directly loaded in the data analysis software, thus saved time and resources associated with the data entry process. Conclusions : The current article helps researchers with planning the study design and choosing of the right data collection method.

Executive Summary As a longtime supporter of domestic violence and sexual assault service providers in North Carolina, the Z. Smith Reynolds Foundation (ZSR) has worked to strengthen the field’s provision of services, its operational capacity, its identification of sustainable funding sources, its articulation of policy priorities, and the development of outcomes assessment tools. With regard to the latter, ZSR has devoted specific attention to the development of data-driven strategies to reduce rates of domestic violence and sexual assault. This project analyzes the development of a new statewide data collection tool for victims of domestic violence and sexual assault in North Carolina. Given that the utilization of domestic violence and sexual assault services is growing annually, the development of a tool to effectively track service outcomes is timely and relevant. A data collection tool has both short-term and long-term benefits. In the short-term, it has the potential to dramatically ease the reporting process for agencies, while also synchronizing what gets reported. Better reporting mechanisms also increase opportunities for funding and strengthen an agency’s ability to advocate for more resources to support their services. ZSR’s particular focus is on the tool’s long-term benefit of providing North Carolina with a set of aggregate...

As Android smartphones gain popularity, industry and government will face increasing pressure to integrate them into their environments. The implementation of these devices on an enterprise can save on costs and add capabilities previously unavailable; however, the organizations that incorporate this technology must be prepared to mitigate the associated risks. These devices can contain vast amounts of personal and work-related data that can impact internal investigations, including (but not limited to) those of policy violations, intellectual property theft, misuse, embezzlement, sabotage, and espionage. Physical access has been the traditional method for retrieving data useful to these investigations from Android devices, with the exception of some limited collection abilities in commercial mobile device management systems and remote enterprise forensics tools. As part of this thesis, a prototype enterprise monitoring system for Android smartphones was developed to continuously collect many of the data sets of interest to incident responders, security auditors, proactive security monitors, and forensic investigators. Many of the data sets covered were not found in other available enterprise monitoring tools. The prototype system neither requires root access privileges nor exploiting weaknesses in the Android architecture for proper operation...

This paper presents the results of research on the development and application of a custom-made truck cycle and delay automated data collection system (TCD-ADCS) in a surface coal mining. Truck cycle and delay field data are locally stored in trucks and then synchronized and replicated through a wireless network into a centralized server containing an already-developed integrated production management system (IPMS). The system relies on motion sensing and distance travelled in order to automatically define the cycle starting/ending points, cycle time, position, and delay time. Connectivity and communication between loading equipment and trucks are also established. Communication between the equipment operators and TCD-ADCS system is via a user-friendly graphic interface. The hardware used for the development of this system consists of a rugged touch-screen personal computer, 2.4 GHz radio transmitter antenna, and a commercial GPS receiver. The system was developed, tested, and deployed at a surface coal mine in the USA.
