The increasingly aging population has inspired a great deal of research in the prevention of fall injuries. A pragmatic and accurate technique to predict fall incidence, along with a corresponding mobile phone app, is proposed in this paper. The technique aims to integrate the benefits of traditional medical history based paradigm and non-historical paradigm and overcome the disadvantage on both paradigms,...
A Cyber-physical system (CPS) is an engineering system made of computational components, i.e. cyber elements, and physical elements, that are connected by a communication network. CPSs have emerged as the contemporarily leading technology in major industry sectors such as manufacture, aerospace, automotive, etc. Nowadays CPS is almost the synonym of control systems for large and complex engineering...
With the development of smart grid, distribution networks reconfiguration becomes more and more important in distribution automation. Combining with distribution networks configuration, this paper proposes a Discrete Firefly Algorithm and a new update operation strategy that suits the algorithm. Firstly, the algorithm uses decimal encoding strategy to shorten the code length and avoid producing unavailable...
Major challenges faced by connected intelligent vehicles, particularly autonomous vehicles, include complexity, dynamics, concurrency, timing, safety, security, and reliability. Among them, the complexity is the key factor for vehicle design. Cyber-physical systems (CPSs) are systems consisting of computational components and physical elements. In this paper a declarative CPS modeling framework is...
Autonomous Underwater Vehicles (AUVs) present an enormous application potential, and the real time accurate position and attitude information is important for AUVs. In order to obtain comprehensive and accurate position and attitude data of AUVs, focusing on the common low cost sensors configuration, the data fusion problem of SINS/USBL/AHRS combination is presented and studied in this paper. Firstly,...
In this paper, a new and efficient method is proposed by using wireless sensor networks in on-line monitoring of large electrical equipment to solve the problems of existing on-line monitoring system that wiring too complicated, causing fault diagnosing, maintaining difficulty and so on. The features are described range from CC2431 system-on-chip to TinyOS which is a wireless sensor networks operating...
Attitude determination system (ADS) that use inexpensive sensors and are based on computationally efficient and robust algorithms are indispensable for real-time vehicle navigation, guidance and control application. This paper describes an attitude determination system that is based on accelerometer and rate gyro. The algorithm is based on a extended Kalman filter. Using integration of angular rates...
