Wireless Sensor Networks (WSN) has become cardinal towards the implementation of smart home, and they are proved to be a permitting technology for assisted living. WSNs are deemed appropriate for placement in home environments for diverse applications. The wireless sensors and actuators offer magnificent opening on energy savings, monitoring and enhancing the level of comfort to the inhabitant, towards...
Food intake levels, hydration, chewing and swallowing rate, and dietary choices are all factors known to impact one's health. This paper presents a novel wearable system in the form of a necklace, which aggregates data from an embedded piezoelectric sensor capable of detecting skin motion in the lower trachea during ingestion. We propose an algorithm based on spectrogram analysis of piezoelectric...
Pressure ulcers, commonly called bedsores, are defined as injuries to the skin and underlying tissue resulting from prolonged pressure usually on bony areas of the body, such as heels and hips. In order to alleviate pressure accumulation at high-risk regions, the current practice in clinics requires caregivers to reposition their patients every two hours. This relies on the engagement of nursing services...
Current studies have produced a plethora of remote health monitoring (RHM) systems designed to enhance the care of patients with chronic diseases. Many RHM systems are designed to improve patient risk factors for cardiovascular disease, including physiological parameters such as body mass index (BMI) and waist circumference, and lipid profiles such as low density lipoprotein (LDL) and high density...
This paper presents the design of an on-bed rehabilitation exercise monitoring system that utilizes a high density sensor bedsheet to evaluate active range of motion exercises. We propose and develop a novel framework to analyze the progression of pressure image sequences using manifold learning. The image sequences are reduced to a low dimensional subspace that can be measured against expected prior...

This paper presents a indices-based dispatching support system which provides a hierarchical multi-level multi-department structure to combines a management-level and technical level to the system operators. By digging a “past” state, monitoring a “present” state and forecasting a “future” state, a comprehensive system operation can be realized. The advanced dispatching operation can be further provided...
At the first stage of this work, waste printed circuit board was pyrolyzed under vacuum in a self-made batch pilot scale fixed bed reactor, and the glass fiber (GF) was separated from the pyrolysis residues by gravity method and purified by calcination in the air. Then, the GF/polypropylene (PP) composites was prepared by means of injection molding. The influence of GF particle size, mass fraction...
Applications of sensor networks in healthcare have undergone major changes in recent times. Implanted wireless sensor devices inside the human body to monitor the activities are a reality now. A new field called the Wireless Body Area Networks (WBAN or BAN) has emerged as a hot research area. To fulfill the needs for a common standard and solve the issues in this emerging field, IEEE has proposed...
This paper proposes a set of on-line monitoring system for capacitive traction power equipments applied in high-speed railway, such as high-voltage bushing, current transformer, potential transformer, and zinc oxide arrester. The electric circuit for the on-line system including zero-flux type current sensor and data acquisition unit is described in detail. The accuracy is enhanced by applying the...
In order to resolve the problems about public transport in Xi'an, this paper pointed out an effective way to establish an Advanced Public Transport System(APTS) which adapt to the development of Xi'an urban transportation based on the theory of APTS. Then a framework about Xi'an APTS was put forward. It particularly analyzed the functions of the various subsystems of the APTS in Xi'an in a systematic...
