Persuasive Technology In Mobile Applications Promoting Physical Activity: A Systematic Review, John Matthews, Khin Than Win, Harri Oinas-Kukkonen, Mark Freeman Jan 2016

Persuasive Technology In Mobile Applications Promoting Physical Activity: A Systematic Review, John Matthews, Khin Than Win, Harri Oinas-Kukkonen, Mark Freeman

Faculty of Engineering and Information Sciences - Papers: Part A

Persuasive technology in mobile applications can be used to influence the behaviour of users. A framework known as the Persuasive Systems Design model has been developed for designing and evaluating systems that influence the attitudes or behaviours of users. This paper reviews the current state of mobile applications for health behavioural change with an emphasis on applications that promote physical activity. The inbuilt persuasive features of mobile applications were evaluated using the Persuasive Systems Design model. A database search was conducted to identify relevant articles. Articles were then reviewed using the Persuasive Systems Design model as a framework for analysis ...


Balance Improvement Effects Of Biofeedback Systems With State-Of-The-Art Wearable Sensors: A Systematic Review, Christina Ma, Duo Wong, Wing K. Lam, Anson Wan, Winson Lee Jan 2016

Balance Improvement Effects Of Biofeedback Systems With State-Of-The-Art Wearable Sensors: A Systematic Review, Christina Ma, Duo Wong, Wing K. Lam, Anson Wan, Winson Lee

Faculty of Engineering and Information Sciences - Papers: Part A

Falls and fall-induced injuries are major global public health problems. Balance and gait disorders have been the second leading cause of falls. Inertial motion sensors and force sensors have been widely used to monitor both static and dynamic balance performance. Based on the detected performance, instant visual, auditory, electrotactile and vibrotactile biofeedback could be provided to augment the somatosensory input and enhance balance control. This review aims to synthesize the research examining the effect of biofeedback systems, with wearable inertial motion sensors and force sensors, on balance performance. Randomized and non-randomized clinical trials were included in this review. All studies ...


Fundamentals And Applications Of Inertial Microfluidics: A Review, Jun Zhang, Sheng Yan, Dan Yuan, Gursel Alici, Nam-Trung Nguyen, Majid Ebrahimi Warkiani, Weihua Li Jan 2016

Fundamentals And Applications Of Inertial Microfluidics: A Review, Jun Zhang, Sheng Yan, Dan Yuan, Gursel Alici, Nam-Trung Nguyen, Majid Ebrahimi Warkiani, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

In the last decade, inertial microfluidics has attracted significant attention and a wide variety of channel designs that focus, concentrate and separate particles and fluids have been demonstrated. In contrast to conventional microfluidic technologies, where fluid inertia is negligible and flow remains almost within the Stokes flow region with very low Reynolds number (Re < 1), inertial microfluidics works in the intermediate Reynolds number range (~1 < Re < ~100) between Stokes and turbulent regimes. In this intermediate range, both inertia and fluid viscosity are finite and bring about several intriguing effects that form the basis of inertial microfluidics including (i) inertial migration and (ii) secondary flow. Due to the superior features of high-throughput, simplicity, precise manipulation and low cost, inertial microfluidics is a very promising candidate for cellular sample processing, especially for samples with low abundant targets. In this review, we first discuss the fundamental kinematics of particles in microchannels to familiarise readers with the mechanisms and underlying physics in inertial microfluidic systems. We then present a comprehensive review of recent developments and key applications of inertial microfluidic systems according to their microchannel structures. Finally, we discuss the perspective of employing fluid inertia in microfluidics for particle manipulation. Due to the superior benefits of inertial microfluidics, this promising technology will still be an attractive topic in the near future, with more novel designs and further applications in biology, medicine and industry on the horizon.


Single Joint Robotic Orthoses For Gait Rehabilitation: An Educational Technical Review, Shahid Hussain, Prashant K. Jamwal, Mergen H. Ghayesh Jan 2016

Single Joint Robotic Orthoses For Gait Rehabilitation: An Educational Technical Review, Shahid Hussain, Prashant K. Jamwal, Mergen H. Ghayesh

Faculty of Engineering and Information Sciences - Papers: Part A

Robot-assisted physical gait therapy is gaining recognition among the rehabilitation engineering community. Several robotic orthoses for the treatment of gait impairments have been developed during the last 2 decades, many of which are designed to provide physical therapy to a single joint of the lower limb; these are reviewed here. The mechanism design and actuation concepts for these single joint robotic orthoses are discussed. The control algorithms developed for these robotic orthoses, which include trajectory tracking control and assist-as-needed control, are described. Finally, the mechanism design and control of single joint robotic orthoses are discussed. There is a strong need ...


A Review On Numerical Solutions To Self-Heating Of Coal Stockpile: Mechanism, Theoretical Basis, And Variable Study, Jian Zhang, Ting X. Ren, Yuntao Liang, Zhongwei Wang Jan 2016

A Review On Numerical Solutions To Self-Heating Of Coal Stockpile: Mechanism, Theoretical Basis, And Variable Study, Jian Zhang, Ting X. Ren, Yuntao Liang, Zhongwei Wang

Faculty of Engineering and Information Sciences - Papers: Part A

Self-heating or even spontaneous combustion of stockpiled coal, which is likely to outbreak under favourable circumstances during its transport, process, and storage, is a long-standing thermal dynamic hazard. This hazard is harmful in diverse aspects: causing loss of coal resource and caking property, raising safety concerns upon occurrence of open fire, and giving off noxious/greenhouse effect gases. Due to the complexity of involved physical process (e.g. heat and mass transport) and chemical process (e.g. coal oxidation), formulating an analytical solution to the problem with or even without a transient approach would be a daunting task and the ...

The application of renewable energy such as solar photovoltaic (PV), wind and fuel cells is becoming increasingly popular because of the environmental awareness and advances in technology coupled with decreasing manufacturing cost. Power electronic converters are usually used to convert the power from the renewable sources to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of these green generation systems, to provide the maximum power point tracking (MPPT) control, and to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load ...


A Review Of Protection Systems For Distribution Networks Embedded With Renewable Generation, Joel Kennedy, Philip Ciufo, Ashish P. Agalgaonkar Jan 2016

A Review Of Protection Systems For Distribution Networks Embedded With Renewable Generation, Joel Kennedy, Philip Ciufo, Ashish P. Agalgaonkar

Faculty of Engineering and Information Sciences - Papers: Part A

The rapid growth of grid-connected embedded generation is changing the operational characteristics of power distribution networks. Amongst a range of issues being reported in the research, the effect of these changes on so-called 'traditional protection systems' has not gone without attention. Looking to the future, the possibility of microgrid systems and deliberate islanding of sections of the network will require highly flexible distribution management systems and a re-design of protection strategies. This paper explores the envisaged protection issues concerned with large penetrations of embedded generation in distribution networks extending into auto-reclosure and protection device coordination. A critical review of recently ...

Interest in ultrafine-grained (UFG) materials has grown rapidly in past 20 years. This review focuses on the application of special rolling techniques for improvement of the mechanical properties of UFG metal sheets. These techniques include asymmetric rolling, cryorolling, asymmetric cryorolling, cross-accumulative roll bonding, and skin-pass rolling. The techniques also include a combination of processes such as equal channel angular press and subsequent rolling, combined high-pressure torsion and subsequent rolling, as well as combined accumulative roll bonding and subsequent asymmetric rolling. We also discuss the main mechanisms leading to improvement in the ductility of UFG materials related to the special rolling ...
