The QARTOD methodology of a standard sequential string of tests on individual measurements has high applicability to constrained data systems. The QARTOD methodology has the benefit of a coherent and replicable test structure that enables relatively easy expansion into new measurements. However, as data streams become more complex the series of tests described becomes increasingly difficult to analyse...
Ocean Networks Canada (ONC) is a not-for-profit society that operates and manages innovative cabled observatories which supply continuous power and Internet connectivity to scientific instruments located in coastal, deep-ocean, and Arctic environments. The data from the instruments are archived, quality-controlled, and made freely available to researchers, educators, and the public. The Oceans 2.0...
Traditionally unmanned undersea vehicles (UUVs) have been large, complex and expensive. Development of UUVs has been driven by defense and commercial requirements. This has allowed for extensive research and development budgets and long development cycles. This paper briefly discuses these historic drivers and how this situation has changed. It focuses on a new compact affordable UUV. In 2015, several...
Telehealth relies on the ability of Information and Communication Technology (ICT) to maximize the quality of care provided remotely. Remote Patient Monitoring (RPM) is a key part within telehealth that enables patient to use devices to measure vital signs and sends it to a healthcare professional. Patients usually have multiple devices to measure vital signs. Those devices might be manufactured by...
Internet of Things is a growing market. Given the keen interest wide public is showing, manufacturers keep launching new models and types each day, trying to connect the real world to Internet. However, while trying to connect everything in our life, manufacturers are facing new challenges that may impact this market growth. In this work, we tackle these challenges and how we can face them by proposing...
Dedicated Short Range Communications (DSRC), a promising vehicle-to-vehicle communication technology, has been under active research and large scale DSRC deployment is expected to start shortly. However, before all vehicles are deployed with DSRC, there will be a relatively long partial DSRC deployment period where DSRC-equipped vehicles and non-DSRC-equipped vehicles both exist on roads. More importantly,...
The evolving in Internet of Things and the plenty diversity of electronic components bring challenges and demand high level tools to improve the application development process. Concurrent computing is useful for catching the logic structure of a problem or solution and handling different and independent components, which is convenient in this context. Therefore, in this paper is presented a library...
All vehicles produced today must be fitted with an On-Board Diagnostic (OBD) interface. With the help of the OBD a data connection through the Controller Area Network (CAN) is realized with the Engine Control Unit (ECU). This control unit is instrumental in optimizing the engine performance. There are many OBD adapters on the market today, ranging from the cheap Do-It-Yourself kind to expensive, professional...
Monitoring workplace activities (what, who, when and where) is beneficial for workforce management. Wearable Recognition enables efficient activities recognition and inferring workplace activities from wearable sensors is attractive but complex. This paper studied the feature extraction of wearable sensory data to uncover the applicability and robustness of wearable sensing approach to activity recognition...
This paper aims to evaluate the processes in the information processing chain of Internet of Things (IoT) applications from the perspective of value added by the processes. This innovative approach focuses on value architectures rather than technical network architectures. The goal is to lay the foundation for a reference process model for industrial IoT applications, which is capable to compare the...
The paper proposes a customized frequency domain energy detection spectrum sensing scheme. It is needed to fulfill requirements provided by the IEEE 802.22 standard, aimed at extending Internet services to Television White Space frequencies. It provides a detection scheme allowing to achieve strict sensitivity required by the protocol either in sensing time or in detection capabilities. In particular,...
This paper describes the design and setup of different measuring systems for the calibration of commercial voltage and current transformer test sets for non-conventional instrument transformers. The calibration systems are recently developed at the national metrology institutes VSL, PTB, METAS and TUBITAK within the frame of the European project “FUTURE GRID — Non-conventional voltage and current...
Beaconing is a basic communication process taking place in Vehicular Ad Hoc Networks (VANETs) to achieve cooperative awareness among vehicles on the road. It is actually a paradigm of information spreading among peer-agents, where each node of a networks sends periodically broadcast messages containing information collected by the node itself. A trade-off arises between the update frequency of the...
The determining problem of several fracton mixture srtucture of materials grinding in the gas jet mill is considered. The problem is solved by comparing the standard deviation of the standart power spectral density of acoustics signals of individual fractions and of the mixture ones.
The paper deals with an impedance measurement technique that could be real time executed by smart transducers. The technique is based on a standardized data structure (in the following named MCT), that is a new way to represent sampled signals within transducer interface modules, as defined in the standard IEEE 21451-001-2017. At first, the MCT data structure is briefly presented. Then the impedance...
This paper presents a trimming correction technique to calibrate the offset in capacitive readout circuits of MEMS sensors. The technique relies on a N-bit digital voltage divider which allows to implement an equivalent variable capacitor with sub-femto Farad step variations. To reduce area occupation, a hybrid approach entailing both resistive and capacitor voltage dividers is introduced. Design...
In the next future, IoT systems will be “ubiquitous” and “pervasive”, bringing several benefits to mankind and also many issues about interoperability, security and privacy. The intrinsic vulnerabilities of IoT devices, with limited resources and heterogeneous technologies, together with the lack of specifically designed IoT standards, represent a fertile ground for the expansion of specific cyber...
In this paper we present accurate thermo-mechanical simulations of a MEMS gyroscope sensor, with its die-level package. The models, simulation tools, methodology and results are presented. The resonance frequency shifts of the modes of interest (drive and 3 sense modes) and the shift in sense capacitances are simulated and compared to experimental results. Simulations compare well with the results.
The aim of this study was to assess the repeatability of the EMED®-A and identify the repeatability of data for different types of measurements (walking without load, walking with load, standing without load, and standing with load). Each load weighing 1.5 kg must be hold at left and right hands. Contact area (CA), maximum force (F), peak pressure (PP) were calculated. In addition, coefficient of...
In this Web 2.0 era, billions of social media users contribute massive amounts of information that have already been presented in earth observation (EO) applications such as earthquake information reporting, flood monitoring, and wildfire alerting. Nevertheless, applying social media data in geo-sensing missions directly and effectively remains a challenge. In this paper, we examine how to design...
