Context-aware systems for smart environments can be very complex and demanding for developers especially in distributed computing and communication environments. We propose a new development infrastructure, that targets this challenge by improving the general system's scalability and traceability. The infrastructure has been developed for and tested in two research labs for smart environments and...
The questions connected with the use of the modern element base in the development of some types of monitoring and monitoring systems for large-scale objects are considered.
Overhead distribution lines are usually subject to voltage transients during thunderstorms. Lightning flashes, whether direct or indirect, are one of the main causes of power quality disturbances on the electric grid. In this paper, a methodology to establish a correlation between the incidence point of a lightning flash, the stroke current amplitude and polarity and its effects on the electric distribution...
Cancer related fatigue is a chronic disease that may persist up to 10 years after treatment of cancer has been finished successfully and is one of the most prevalent problems of cancer survivors. Cancer related fatigue is a complex symptom that is not sufficiently understood and difficult to remedy. Patients do not necessarily follow a treatment plan with regular in-office follow-ups. As a consequence,...
As the number of devices (things) connected to the Internet (Internet of things: IoT) is growing, achieving robust security and privacy (S&P) is becoming increasingly challenging. With the heavy use of medical things (MT), the S&P in the medical domain poses a serious issue that continues to grow. Due to the criticality and sensitivity of the data in the healthcare domain, ensuring...
Non-invasive, environmental monitoring is being successfully utilised to improve health care outcomes for patients while allowing them to more safely and comfortably live in their homes instead of health care facilities. This promises to reduce costs and ease the health care burden for many countries globally. However, these systems are still in early stages of research and only highly skilled researchers...
In the past period, great efforts have been made to develop methods for people detection based on monitoring their respiratory motion using ultra-wide band sensors (radars). The basic principle of these methods consists in the detection of signal components of raw radar data possessing a significant power in the frequency band 0.1 Hz-0.7 Hz (a frequency range of human respiratory rate) for a constant...
We have been developing a monitoring system to measure human information from human body. In the previous study, we developed a digital integrated circuit that enables acquisition of heart rate from ECG (Electrocardiogram) instead of MPU (Micro Processing Unit). This circuit reduced the power consumption of the MPU from 97 μW to 19.7 μW. In this research, we redesigned an MPU specialized for the human...
The Smart domestic protection monitoring gadget has been designed developed, examined and validated. It makes use of the RF (radio frequency) generation to monitor the reputation and security of the electrical device. The gadget has been used to store energy. The clever home is a complex era, on the equal time it is growing, the era that used in this research are Global System for virtual cellular...
High data quality and low sensing cost are two primary goals in large-scale mobile crowdsensing applications. The oversampling and the undersampling are common problems which always result in a high cost or low data quality that can not satisfy the system requirement. To address this problem, taking into account low-rank latent structure, we propose a compressive and adaptive data sampling scheme...
A nodes scheduling method applying for high density and large-scale WSN is put forward by using probabilistic coverage sensing model in this paper-that is the Distributed Probabilistic Coverage Sets Configuration Method (DPCS). In this method, the nodes with dense distribution are divided into several non-overlapping coverage sets by adopting distributed self-organization method. In the process of...
Aiming at the problem of sensor node deployment in underwater wireless sensor networks(UWSNs), the doublecoverage algorithm is proposed to solve the premature failure caused by excessive energy consumption. First of all, the coverage area of node is divided into grid around the mobile sensor network with AUV. Then the sensor node is analyzed to design the sensor node sensing model and the sensor node...
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...
The population growth and the parallel increase in health spending, inadequate number of physicians and the growing interest of people to access health services in the comfort of their own homes necessitated a serious transformation in health systems. This has prompted health professionals to conduct research to develop solutions that enable them to monitor and assess patients' health remotely. In...
Interlacing is commonly used in textile industries to produce cohesion points (knots) in a multi-filament yarn. The knots distance needs to be controlled on-line since its regularity guarantees a homogeneous appearance of the final fabric. Here, we investigated two techniques for the on-line monitoring of the multi-filament yarn interlacing. The high speed imaging of the yarn motion in an interlacer...
Energy autonomy is a crucial bottleneck for consumer electronics and low-cost devices that are a pillar for the Internet of Things era. In this work, we present a self-sustainable sensor device that drives an e-paper digital display powered by the energy produced by colonies of electrogenic bacteria in symbiosis with plants. The power management subsystem has been designed to meet the requirements...
This work proposes the design and evaluation of a wearable mobile ear-based electrocardiogram (ECG) monitoring system using highly electrically conductive material — graphene — enabled electrodes. Prolonged physiological monitoring is important in diagnosis, monitoring chronic diseases, and improving training regimes. Current technologies for monitoring ECGs alone are acceptable to clinicians or professionals,...
Temperature (T) and pH variations affect the function of electrochemical sensors. The study of their effects on point-of-care medical sensors is vital due to their delicate use. An example comes from anesthesia where difficult-to-dose drugs are infused in patient's blood, e.g. propofol. In this case, a drug concentration monitoring system is required. However, blood pH and T can vary during anesthesia,...
The Internet of Things systems consist of devices, sensors, and services that enable tangible objects to gather and transmit information about the physical world. In order to deliver their main functionality, some of these systems collect a very significant amount of data obtained from their sensors located in living spaces and office environments. This data may hide some interesting behavioral patterns...
This paper proposes a method to monitor driver's movement using capacitive electrocardiogram (ECG) sensors. The sensor measures ECG by sensing voltage changes in our body, and voltage changes according to the movement of the body also can be measured by the sensor. The proposed method uses independent component analysis to decompose the signal component related to the body movement in the measured...
