The purpose of the present study was to evaluate the feasibility of blood pressure (BP) estimation by means of pulse arrival time (PAT) from data records of ICU patients available at the MIMIC public database. Datasets consisting of ECG, PPG and arterial BP waveforms from 8 subjects were used for the analysis and the relationship of PAT with systolic, diastolic and mean blood pressure was assessed...
Telephone buried cable (BC) protection is an essential demand to perform successful wired telecommunication system against theft. Data logging from sensor and electronic communication system can monitor buried cable state to ensure exist of the buried cable to be protected. A number of parameters are associated with telephone buried cable, thus different types of sensors are required to measure the...
Along with the trend of computer technology, programming skill becomes the core competency of the future world, which highlights the importance of programming education. However, most of the related literature indicated that programming is difficult to be tackled for both learners who learn it and teachers who teach it. Despite of the importance, there are only a few cases in which teachers adopt...
A commonly recognised and significant problem faced by those suffering from addiction to drugs and alcohol and other substances (or repetitive patterns of behaviour) is the lack of easily accessed, educational technologies currently available to them. Recovery based material exists but there is no cohesive option which is able to offer a fully multi-media opportunity for: self-reflection, communication...
This paper deals with the extremely pertinent problem of web crawling, which is far from trivial considering the magnitude and all-pervasive nature of the World-Wide Web. While numerous AI tools can be used to deal with this task, in this paper we map the problem onto the combinatorially-hard stochastic non-linear fractional knapsack problem, which, in turn, is then solved using Learning Automata...
A dramatic shift in population ageing is taking place, which is subsequently leading to a rise in the prevalence of chronic conditions. COPD is one such condition that places a heavy burned on national Health Services. A healthier lifestyle can greatly reduce the speed of conditional decline in those with COPD and therefore provide a better quality of life. This paper investigates how technology can...
Data logger is a key component in building a telemetry system. Using the telemetry system, the activity measurements of an object and retrieval of measurement data can be done remotely (remote). Universal Data Logger (UniDalog), the data logger is a device that has ability to store measurement data, download the data remotely, as well as setting of data logger and remote sensor calibration. By utilizing...
In this study sol-gel technique was used to prepare Al-, V- and In-doped ZnO. The morphology and microstructure of samples synthesized was characterized by means of different techniques such as X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM). The characterization results indicated that all as-prepared doped samples maintains the same morphology and microstructure...
In this paper we present a new gamified learning system called Reflex which builds on our previous research, placing greater emphasis on variation in learner motivation and associated behaviour, having a particular focus on gamification typologies. Reflex comprises a browser based 3D virtual world that embeds both learning content and learner feedback. In this way the topography of the virtual world...
The goal of this paper is to introduce an experimental monitoring system for thermoelectric generator modules. This system consists in using thermoelectric generator devices for producing electrical power. Also it monitors some parameters of a thermoelectric generator such as the temperature of its cold side, the temperature of its hot side, the output voltage, the output current. The system is able...
Wireless and fully energetically passive corrosion sensors are presented for the monitoring of degradation of infrastructures located in coastal zones and marine environments. Their application concerns thus marine offshore, wind energy industry as well as harbor maintenance procedures. Several sensitive parts and architectures will be presented at the conferences. In this paper, an example of such...
Students' goal orientations impact their self-regulation, engagement, and achievement in post-secondary STEM courses. But, how students' goal orientations change across a semester and the impacts of these changes have not been extensively studied. Study purposes were to investigate goal orientation change across the semester, associations of goal change with achievement and self-regulation, and associations...
According to the demand of monitoring hierarchical execution process of complex product, this paper puts forward a technology about coordination of the production process associated with complex product based on Task-Kitting Process. From supervisory of complex associated production, This paper takes process-oriented multi-parametric monitored modeling and processed dynamic assembly monitoring packet...
Years of unbridled growth, with no respect for rules, in many cases due to the absence of effective monitoring tools, have produced in some localized areas of Italy the so-called eco-monsters, to which a state of widespread pollution due to multiple anthropogenic causes must be added. In this paper a review of current and emergent available techniques, materials and tools for water monitoring is presented;...
Off-body detection of respiratory and cardiac activity presents an enormous opportunity for general health, stress and sleep quality monitoring. The presented setup detects the mechanical activity of both heart and lungs by measuring pressure difference fluctuations between two air volumes underneath the chest area of the subject. The registered signals were characterized over four different sleep...
A proposta do artigo é apresentar o trabalho realizado para permitir a aplicação de conversores de frequência ou variable speed drives (VSD), de baixa tensão com conceito modular na aplicação de bombeio centrífugo submerso (BCS), de modo a permitir uma rápida substituição em caso de falha e diminuir assim o tempo médio para reparo (TMPR). Desta forma, torna-se possível minimizar a perda de produção...
Aterramento do neutro é uma questão de grande importância nos sistemas elétricos das indústrias de petróleo, química, gás e outras indústrias. Essa importância se deve ao fato de que cerca de 85% dos curto-circuitos que ocorrem em sistemas elétricos industriais são fase-terra, o que pode causar sobretensões transitórias, arco elétrico, incêndio danos em pessoas e encerramento do processo industrial...
O uso de Conjuntos de Manobra e Controle de Potência (CMCP) nos sistemas elétricos industriais (SEI) típicos das indústrias petroquímicas, tanto de média quanto de baixa tensão, se depara com diferentes desafios, associados a sua especificação e operação, para se obter soluções que garantam a qualidade da energia elétrica a ser distribuída. Muito destes problemas estão relacionados aos seus componentes,...
To solve the real-time material delivery problems from the warehouse to workstations for the mixed model automotive assembly line in accordance with the production cycle, the dynamic material delivery method based on internet of things has been developed. The material flow and production characteristic of automotive assembly was analyzed in order to feed material properly & timely. The monitoring...
Certain regions of the world have successfully implemented harmonized product compliance regulations, such as the European Free Trade Association and the Customs Union. Some product types or focus areas have moved to a more harmonized compliance approach and, with this, the regulations and standards are easier to enforce, simpler for consumers to understand, and more efficient for manufacturers to...
