Collaborative Fall Detection Using Smartphone And Kinect, Xue Li, Lanshun Nie, Hanchuan Xu, Xianzhi Wang

Research Collection School Of Computing and Information Systems

Humanfall detection has attracted broad attentions as sensors and mobile devices are increasingly adopted in real-life scenarios such as smart homes. The complexity of activities in home environments pose severe challenges to the fall detection research with respect to the detection accuracy. We propose a collaborative detection platform that combines two subsystems: a threshold-based fall detection subsystem using mobile phones and a support vector machine (SVM)-based fall detection subsystem using Kinects. Both subsystems have their respective confidence models and the platform detects falls by fusing the data of both subsystems using two methods: the logical rules-based and D-S evidence fusion …

Moreover, data integrity is protected by using session reassemble and session partitioning. The simulation results show that the new model enjoys favorable advantages such as …


Simulation-Based Security Of Function-Hiding Inner Product Encryption, Qingsong Zhao, Qingkai Zeng, Ximeng Liu, Huanliang Xu Jan 2018

Simulation-Based Security Of Function-Hiding Inner Product Encryption, Qingsong Zhao, Qingkai Zeng, Ximeng Liu, Huanliang Xu

Research Collection School Of Computing and Information Systems

Functional encryption (FE) [1,2] is a modern type of encryption scheme that extends several previous notions and allows tremendous flexibility in controlling and computing on encrypted data. FE enables an authority to derive constrained decryption keys that are used by a user to obtain specific functions of encrypted messages. Informally, the authority generates a secret key skf for a function f from a master secret key. Then, the user can only learn f(x) from a ciphertext Enc(x) with skf and reveal nothing else about x.

© 2018 The Author(s). Many American universities located in the Middle East try to offer the stamp of higher quality in education that the United States provides and delivers. These institutions are doing an incredible job of providing opportunity for youths of that region to obtain an American education. However, these universities bear the stereotype that they are not applying a genuinely American-style teaching system and methods, but rather an Arabic style with an American name. The research question asks to which extent this stereotype is true. The purpose of the study is to determine if there is/are relationship(s) among …


Dictionary Learning With Structured Noise, Pan Zhou, Cong Fang, Zhouchen Lin, Chao Zhang, Y. Edward Chang Jan 2018

Dictionary Learning With Structured Noise, Pan Zhou, Cong Fang, Zhouchen Lin, Chao Zhang, Y. Edward Chang

Research Collection School Of Computing and Information Systems

Recently, lots of dictionary learning methods have been proposed and successfully applied. However, many of them assume that the noise in data is drawn from Gaussian or Laplacian distribution and therefore they typically adopt the 2 or 1 norm to characterize these two kinds of noise, respectively. Since this assumption is inconsistent with the real cases, the performance of these methods is limited. In this paper, we propose a novel dictionary learning with structured noise (DLSN) method for handling noisy data. We decompose the original data into three parts: clean data, structured noise, and Gaussian noise, and then characterize them …

Securing Display Path For Security-Sensitive Applications On Mobile Devices, Jinhua Cui, Yuanyuan Zhang, Zhiping Cai, Anfeng Liu, Yangyang Li

Research Collection School Of Computing and Information Systems

While smart devices based on ARM processor bring us a lot of convenience, they also become an attractive target of cyber-attacks. The threat is exaggerated as commodity OSes usually have a large code base and suffer from various software vulnerabilities. Nowadays, adversaries prefer to steal sensitive data by leaking the content of display output by a security-sensitive application. A promising solution is to exploit the hardware visualization extensions provided by modern ARM processors to construct a secure display path between the applications and the display device. In this work, we present a scheme named SecDisplay for trusted display service, it …

Specifically, for the fog servers, we design a new secure outsourced inner-product protocol for achieving secure lightweight single-layer neural network. Also, a privacy-preserving piecewise polynomial calculation protocol allows cloud server to securely perform any activation functions in multiple-layer neural network. Moreover, …


Smartwatch-Based Early Gesture Detection & Trajectory Tracking For Interactive Gesture-Driven Applications, Tran Huy Vu, Archan Misra, Quentin Roy, Kenny Tsu Wei Choo, Youngki Lee Jan 2018

Smartwatch-Based Early Gesture Detection & Trajectory Tracking For Interactive Gesture-Driven Applications, Tran Huy Vu, Archan Misra, Quentin Roy, Kenny Tsu Wei Choo, Youngki Lee

Research Collection School Of Computing and Information Systems

The paper explores the possibility of using wrist-worn devices (specifically, a smartwatch) to accurately track the hand movement and gestures for a new class of immersive, interactive gesture-driven applications. These interactive applications need two special features: (a) the ability to identify gestures from a continuous stream of sensor data early–i.e., even before the gesture is complete, and (b) the ability to precisely track the hand’s trajectory, even though the underlying inertial sensor data is noisy. We develop a new approach that tackles these requirements by first building a HMM-based gesture recognition framework that does not need an explicit segmentation step, …


Integrated Reward Scheme And Surge Pricing In A Ride Sourcing Market, Hai Yang, Chaoyi Shao, Hai Wang, Jieping Ye Jan 2018

Integrated Reward Scheme And Surge Pricing In A Ride Sourcing Market, Hai Yang, Chaoyi Shao, Hai Wang, Jieping Ye

Research Collection School Of Computing and Information Systems

Surge pricing is commonly used in on-demand ride-sourcing platforms (e.g., Uber, Lyft and Didi) to dynamically balance demand and supply. However, since the price for ride service cannot be unlimited, there is usually a reasonable or legitimate range of prices in practice. Such a constrained surge pricing strategy fails to balance demand and supply in certain cases, e.g., even adopting the maximum allowed price cannot reduce the demand to an affordable level during peak hours. In addition, the practice of surge pricing is controversial and has stimulated long debate regarding its pros and cons. In this paper, to address the …


User-Friendly Deniable Storage For Mobile Devices, Bing Chang, Yao Cheng, Bo Chen, Fengwei Zhang, Wen-Tao Zhu, Yingjiu Li, Zhan. Wang Jan 2018

User-Friendly Deniable Storage For Mobile Devices, Bing Chang, Yao Cheng, Bo Chen, Fengwei Zhang, Wen-Tao Zhu, Yingjiu Li, Zhan. Wang

Research Collection School Of Computing and Information Systems

Mobile devices are prevalently used to process sensitive data, but traditional encryption may not work when an adversary is able to coerce the device owners to disclose the encryption keys. Plausibly Deniable Encryption (PDE) is thus designed to protect sensitive data against this powerful adversary. In this paper, we present MobiPluto, a user-friendly PDE scheme for denying the existence of sensitive data stored on mobile devices. A salient difference between MobiPluto and the existing PDE systems is that any block-based file systems can be deployed on top of it. To further improve usability and deniability of MobiPluto, we introduce a …


Assessment Of The Neuroprotective Efficacy Of Poly-Arginine-18 (R18) Peptides In A Pre-Clinical Model Of Perinatal Hypoxic-Ischaemic Encephalopathy (Hie), Adam Edwards Jan 2018

Assessment Of The Neuroprotective Efficacy Of Poly-Arginine-18 (R18) Peptides In A Pre-Clinical Model Of Perinatal Hypoxic-Ischaemic Encephalopathy (Hie), Adam Edwards

Theses

Hypoxic-ischaemic encephalopathy (HIE) is one of the leading causes of mortality and morbidity in infants, globally. This disorder eventuates following a reduction in oxygenated cerebral blood flow to the foetus in utero, leading to excitotoxic-mediated brain cell (e.g. neuron, glia and glial progenitor cell) death. Currently, there is no clinically appropriate neuroprotective treatment to reduce acute brain injury following HIE. Recent studies have demonstrated that poly-arginine and cationic arginine-rich peptides (CARPs; e.g. R18: R = arginine residues) exhibit potent neuroprotective properties in both in vitro and adult animal models of ischaemia, and therefore have the potential to be developed into …


Online/Offline Traceable Attribute-Based Encryption [In Chinese], Kai Zhang, Jianfeng Ma, Junwei Zhang, Zuobin Ying, Tao Zhang, Ximeng Liu Jan 2018

Online/Offline Traceable Attribute-Based Encryption [In Chinese], Kai Zhang, Jianfeng Ma, Junwei Zhang, Zuobin Ying, Tao Zhang, Ximeng Liu

Research Collection School Of Computing and Information Systems

Attribute-based encryption (ABE), as a public key encryption, can be utilized for fine-grained access control. However, there are two main drawbacks that limit the applications of attribute-based encryption. First, as different users may have the same decryption privileges in ciphertext-policy attribute-based encryption, it is difficult to catch the users who sell their secret keys for financial benefit. Second, the number of resource-consuming exponentiation operations required to encrypt a message in ciphertext-policy attribute-based encryption grows with the complexity of the access policy, which presents a significant challenge for the users who encrypt data on mobile devices. Towards this end, after proposing …


Extinguishing Cue-Controlled Reward Choice: Effects Of Pavlovian Extinction On Outcome-Selective Pavlovian-Instrumental Transfer, Tina Seabrooke, Pelley Me Le, Alexis Porter, Chris J. Mitchell Jan 2018

Extinguishing Cue-Controlled Reward Choice: Effects Of Pavlovian Extinction On Outcome-Selective Pavlovian-Instrumental Transfer, Tina Seabrooke, Pelley Me Le, Alexis Porter, Chris J. Mitchell

School of Psychology

Outcome-selective Pavlovian-instrumental transfer (PIT) refers to the finding that presenting Pavlovian predictors of outcomes can enhance the vigor of instrumental responding for those same outcomes. Three experiments examined the sensitivity of outcome-selective PIT to Pavlovian (stimulus-outcome) extinction. In Experiment 1, participants first learnt to perform different instrumental responses to earn different outcomes. In a separate Pavlovian training phase, certain stimuli were established as Pavlovian signals of the different outcomes. Some of these Pavlovian stimuli were then extinguished (they were presented alone, without any outcome), while others were not. A final transfer test measured the extent to which these Pavlovian cues …


Export Market Destination And Performance: Firm-Level Evidence From Sub-Saharan Africa☆, Ousmanou Njikam Jan 2018

Export Market Destination And Performance: Firm-Level Evidence From Sub-Saharan Africa☆, Ousmanou Njikam

Journal of African Trade

This paper uses a novel manufacturing firm-level survey data in 19 sub-Saharan African (SSA) countries to explore the linkages among a number of export-market destinations (e.g., China, India, other Asia, EU, US, MENA, SSA excluding South Africa, and South Africa) and performance. The paper also examines differences between exporters and non-exporters performance and assesses self-selection. We find superior characteristics of exporters relative to non-exporters. Size, foreign ownership and past export experience enhance the propensity to export while continuing exporters outperform switching ones. Export destination matters: exporting to China leads to improvements in total factor productivity (TFP); India destination enhances the …


Aid For Trade And Africa’S Trade Performance: Evidence From Bilateral Trade Flows With China And Oecd Countries☆, Adugna Lemi Jan 2018

Aid For Trade And Africa’S Trade Performance: Evidence From Bilateral Trade Flows With China And Oecd Countries☆, Adugna Lemi

Journal of African Trade

The optimism surrounding aid for trade (AfT) led scholars and practitioners to probe its link with trade performance of aid-recipient countries in Africa. In the absence of formal evaluation guidelines, most previous studies, using aggregate data, have looked into the impacts of AfT on exports and imports and found results consistent with the stated objectives of AfT. The present study investigates the nature of the link for the case of African countries using disaggregated AfT data from China and OECD member countries. The results show that flows of OECD aid to all sectors and to economic infrastructure have increased both …


Understanding Crude Oil Import Demand Behaviour In Africa: The Ghana Case, George Marbuah Jan 2018

Understanding Crude Oil Import Demand Behaviour In Africa: The Ghana Case, George Marbuah

Journal of African Trade

As in many African countries, crude oil importation is a major drain on the economy of Ghana. We estimate short-run and long-run import demand models for crude oil using data over the period 1980–2012. Results show that demand for crude oil is price inelastic in the short-run but elastic in the long-run. Other important drivers of crude oil import are the real effective exchange rate, domestic oil production and population growth. Income is found to be the strongest driver of crude oil demand. Policy implications of our results are presented.
