In this paper, after a brief introduction on the proposed plug-and-play (PnP) process monitoring and control system, two online configuration approaches are proposed for the observer-based residual generator. Firstly, an adaptive residual generator is developed based on the adaptive observer scheme. Aiming at higher feasibility and reliability of industrial application, an iterative learning approach...
We propose a new framework combining dynamic sampling rates for healthcare sensors driven by user behavior, and an adaptive MAC scheduling scheme applied to the time-slotted channel hopping (TSCH) protocol in IEEE 802.15.4, which provides high throughput and reliable communications. First, we introduce a system software architecture for machine-learning-assisted healthcare monitoring that detects...
This paper presents a multi-layer distributed performance management model for Internet of Things (IoT) as a service for caregivers. Performance monitoring and control of IoT devices and services are vital functions for e-health systems. Cloud-based IoT systems with centralized data centers further underline the need for distributed management. The main contribution of this paper is a model and prototype...
Sleep positions have an impact on sleep quality and therefore need to be further analyzed. Current research on position tracking includes only the four basic positions. In the context of wearable devices, energy efficiency is still an open issue. This research presents a way to detect eight positions with higher granularity under energy efficient constraints. Generalized Matrix Learning Vector Quantization...
Recently, as the damage of air pollution due to fine dusts, etc. has been continuously increased, there is a growing need for a low-cost air quality monitoring system to observe air pollution information at public facilities or homes. In this paper, we propose an IoT (Internet of Things)-based atmospheric environment monitoring system which can effectively observe air pollution information without...
This paper deals with the Internet of Things solutions and value chain related to the Smart City domain. Characterization of the IoT services and applications including connectivity requirements is proposed and illustrated with two case studies, on smart parking and air quality monitoring based on urban crowd sensing. Regulatory issues, as well as the role of the national regulatory authority for...
Innovative wellness gadgets are the products of convergence of science and technology in this dynamic digital era. It has not been possible before to provide just-in-time intervention to avoid unhealthy behavior. The change in behavior requires the understanding of the behavior theories and then practical implementation of the stages. Transtheoretical model supports to identify the stage of human...
The paper presents a system that uses Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software to monitor, and to control the state of an electrical machine depending on user imposed limits. In this system, the real-time variables of an electrical machine are measured and transferred to a controller (PC) through Data Acquisition Card (DAQ). The NI USB 6009 DAQ is selected for this project...
Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated with toxic chemicals. Water scarcity and water contamination has been one of the major issues faced...
There has been a growing interest in sweat-based sensors in the past several decades as eccrine sweat contains many metabolites of physiological significance. In particular, perspiration sensing is important not only for wellness monitoring and performance analysis, but also replenishment of metabolically significant ions and metabolites such as Na+, Cl− K+, and glucose. This study aims to develop...
In the decommissioning of the nuclear power plant, especially, for decontamination by radioactive substances caused by 2011 Fukushima nuclear power plant accident has affected the reconstruction after the earthquake, the dose evaluation and validation of the decontamination effect is very important. In order to prepare a novel passive-type dosimeter system which can applied to radiation dose monitoring...
This paper presents the use of a new concept: Internet of Things (IoT), applied to the fermentation process of Cocoa at the Piura's mountain range. A prototype was designed and built with sensors that record the variables of temperature, oxygen and carbon dioxide during the process and send this information to the Internet. Finally a system has been developed that receives this information, visualizes...
Camera-enabled sensors deployed for visual monitoring will cover a region of the target field, providing information for many innovative applications based on wireless sensing. Actually, some areas of the monitored field may have more relevance than others, according to the characteristics of the applications, which may indicate that such areas need better coverage to avoid blind spots and achieve...
This paper proposes a sensorless chatter detection method for a ball screw drive system used in milling, by introducing the mechanical energy factor (MEF). The MEF is an indicator for detecting self-excited chatter, based on the power factor theory used in electric systems, and monitors the phase difference between dynamic cutting force and displacement. By monitoring the MEF, the self-excited chatter...
Paper proposes a kind of multiple environmental parameters monitoring system for granary that is based on ZigBee network and takes ARM controller as core. With regard to hardware, monitoring circuits for temperature, humidity, CO2 concentration and grain water content are designed. With regard to control program, fuzzy intelligent algorithm is designed and transplanted to ARM controller. The test...
IoT technology with the 4.0 revolution in industrial technology promises to change drastically in every aspect of human life. The elderly health care industry is forecasted to grow fastly, providing a more economic and effective method for health monitoring through the utilization of IoT technology. Blood oxygen saturation (SpO2), one of the vital survival parameters, is potentially used in health...
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...
Waiting for service is a problem faced by people from different countries and cultures. The problem of waiting in a queue can bring losses of quality of life and even economic problems. In this paper, we propose a mechanism for automatic detection of wait events via smartphones. This detection is done cooperatively by observing data collected from the user's smartphone's wifi and accelerometer sensors,...
Monitoring of residences and businesses can be effectively performed using machine learning algorithms. As sensors and devices used for monitoring become more complex, having humans process the information to detect intrusions would be expensive and difficult to scale. We propose an automated home/business monitoring system which resides on edge servers performing online learning on streaming data...
