Opportunity and challenge of big data in improving chronic non-communicable diseases： by health system engineering approaches

Chronic non-communicable diseases （NCDs） is a sick- state in the complex system of human body. Healthsystems engineering approach can be used to recover health state by many different ways of system adjustments, including physical exercises, nutrition and psychological intervention, and drug therapies. To evaluate and assess the effects of these adjustments, many parameters of the system states have to be monitored （such as molecular high- throughput technologies, physiological, image, etc.）, and estimated at the different levels （such as molecular, cellular, tissue, organ, and system levels） and on the different dimensions （such as metabolic, immune, neural, etc.） for human system. Huge data have been produced during the whole process, and health systems engineering approach will model health and sick state in the human system by detecting and analyzing these multi-dimension and multi- level big-data in order to find personal suitable adjustment method.

Application of wireless sensor networks to aircraft control and health management systems

Use of fly-by-wire technology for aircraft flight controls have resulted in an improved performance and reliability along with achieving reduction in control system weight. Implementation of full authority digital engine control has also resulted in more intelligent, reliable, light-weight aircraft engine control systems. Greater reduction in weight can be achieved by replacing the wire harness with a wireless communication network. The first step towards fly-by-wireless control systems is likely to be the introduction of wireless sensor networks (WSNs). WSNs are already finding a variety of applications for both safety-critical and nonsafety critical distributed systems. Some of the many potential benefits of using WSN for aircraft systems include weight reduction, ease of maintenance and an increased monitoring capability. This paper discusses the application of WSN for several aircraft systems such as distributed aircraft engine control, aircraft flight control, aircraft engine and structural health monitoring systems. A brief description of each system is presented along with a discussion on the technological challenges. Future research directions for application of WSN in aircraft systems are also discussed.
