As an important equipment to preheat air and to improve coal-fired power plant boiler efficiency with the heat of boiler tail flue gas, the air preheater's safe and economic operation influences unit efficiency directly. At present, above 80% utility-type unit in domestic uses tri-sectional rotary air preheater. Therefore, the rotary air preheater has become an indispensable auxiliary machinery in...
Physical unclonable functions (PUFs) take advantage of the effect of process variation on hardware to obtain their unclonability. Traditional PUF design only focuses on the analog signals of circuits. An arbiter PUF, for example, generates responses by racing delay signals. Implementations of such PUFs usually employ large area and power consumption while providing very low throughput. To address...
Wearables that continuously acquire medically relevant parameters can reduce duration of hospitalizations and derive treatment optimizations for individual patients thus improving the quality of medical treatments. We demonstrate an architecture that includes wearables, edge and cloud computing to provide optimal user interaction and analytics of multi-parameter wearable data to accomplish this goal...
Internet of Things (IoT) can provide interconnection of things, which can promote the achievement of the remote human health monitoring. In this paper, a human health monitoring platform is designed and developed under the application framework of body sensor network of IoT. The platform can collect the physical information of user by constructing the human state acquisition system. And then the collected...
In Internet of Things (IoT) environments, there are multiple sensors and devices monitoring different metrics and producing massive amounts of data. Monitoring of metrics can be done at different frequencies. Systems and applications that consume monitoring data typically use constrained IT resources, e.g., constrained network facilities, storage, display, processing/computing power, and energy. Given...
In internet of things (IT) environment, a sensor interface device is essential for data collection in wireless sensor network (WSN) system for water quality monitoring (WQM) as the water pollution is a critical issue globally. This paper presents the design of a WSN based reconfigurable smart sensor interface device for WQM system in an IoT environment. The system consists of Field Programmable Gate...
It is well known that clustering sensor nodes and letting those with superior resources act as cluster heads help to address the network scalability problem in wireless sensor networks (WSNs). However, the clustered architecture provides the opportunity for an adversary to attack sensor nodes within a cluster by simply compromising the cluster head. This paper investigates the attack detection issues...
Rate of change of the state of polarization was measured in a variety of live networks. Transients produced the highest rates of change and can be localized by measurement. We found strong correlation between Mrad/s transients and lightning strikes in optical ground wire cables.
This paper presents two different ways of identifying possible defects for electronic components in order to achieve predictive maintenance. The analysis is performed on the components of a power station used in telecommunication. In the first part of the paper is performed a defect analysis based on fuzzy graphs. This leads to the components causing the most accidental stops. In the second part an...
Wireless sensor network (WSN) plays an important role in monitoring applications in many areas. This paper presents a WSN called EN-Nets which is based on a newly designed small-size and low-power sensor node (EN-Node) for monitoring real-time environmental conditions. Detailed design and implementation of the sensor node for sensing and communicating environmental parameters are described. A power...
Healthcare is one of important factors for persons to keep their happiness during daily life. In order to maintaining good health conditions, daily continuous health monitoring is effective to find small symptoms before causing severe conditions. In this study, wearable, healthcare sensor sheets are proposed to monitor health conditions and activity, simultaneously, consisted of a skin temperature...
In this paper two acquisition and monitoring systems for electrodermal response are presented. One system is done with an Arduino data acquisition board that has a WiFi module integrated. The second system is based on a data acquisition board that has a dedicated platform for acquiring biological signals integrated, produced by Libelium. The data acquired are transmitted to the computer through a...
The introduction of Internet of Things (IoT) and smart cities is widely viewed as a great opportunity that stimulated the modern view of wireless sensor networks (WSNs). Up to this point, WSNs were application-driven systems with well defined challenges and requirements. The idea of IoT and smart cities increased the amount of available data and magnified the hardware and software challenges of sensor...
Self-awareness is the foundation for many of the nowadays desired system characteristics, such as self-optimization and self-adaption. This awareness is rooted in observation and sensory data obtained by the system regarding itself and its environment. Given the important role which data collection plays in creating this awareness, we believe that it merits more attention than it has so far received...
This paper summarizes the work performed by the authors on development of the sensor network for thermal parameters measurements, as well as structure health monitoring in modern buildings. The described work was carried out as a part of a workpackage within the EC FP7 project SESBE.
It is important to equip future vehicles with an onboard system capable of tracking and analyzing driver state in real-time in order to mitigate the risk of human error occurrence in manual or semi-autonomous driving. This study aims to provide some supporting evidence for adoption of consumer grade electronic devices in driver state monitoring. The study adopted repeated measure design and was performed...
The paper deals with the development and the performance characterization of model-based health-monitoring algorithms for the detection of faults in an electro-mechanical flight control actuator for unmanned aerial system flight controls. Two real-time executable position-tracking algorithms, based on predictors with different levels of complexity, are developed and compared in terms of false alarms...
Within the context of bilateral cooperation between Turkey and Tunisia, a Project called “Development of Intelligent Control Modules for Nano Satellites” was initiated in May 2015. Due to political changes in both countries the Project could effectively start on May 2016. The project aims at developing nanosatellite based water quality monitoring within the MENA region. Turkish side consists of researchers...
Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
Cold chain is a term related to the equipment and processes used to keep the correct temperature, in which the products, such as food, vaccines, blood, tissues, amongst others, should be stable to be preserved. Any change in temperature can cause a damage in the specific properties in products. Because of that, it is mandatory to constantly monitor temperature and log it to offer traceability. Furthermore,...
