Face search in encrypted domain
(Springer, 2015)Visual information of images and videos usually is encrypted for the purposes of security applications. Straightforward manipulations on the encrypted data without requiring any decryption have the advantage of speed over ... -
Falls Risk Assessment for Hospitalised Older Adults: A Combination of Motion Data and Vital Signs
(Springer, 2016)Health monitoring systems have rapidly evolved during the past two decades and have the potential to change the way healthcare is currently delivered. Currently hospital falls are a major healthcare concern worldwide because ... -
Fast release of sulfosalicylic acid from polymer implants consisting of regenerated cellulose/γ-ferric oxide/polypyrrole
(2014)This work presents a comparative study on the rate of drug release from implantable matrices induced by electric and magnetic fields separately for better biomedical applications. The matrices were prepared by coating ... -
Fatigue of Commercially Pure Titanium Dental Implants
(Institute of Problems of Mechanical Engineering, 2016)Failure of two commercially pure titanium dental implants was analysed. The implants fractured at the abutments after only three years use. One abutment failed at the junction of the threaded and unthreaded areas, the other ... -
Fault Ride Through Technique for DFIG-based Wind Turbines Under Grid Three-phase Faults
(IEEE, 2018)In modern power systems with increasing penetration of wind turbines (WTs), improvement of low voltage ride through (LVRT) capability of WTs equipped with doubly-fed induction generators (DFIGs) is an important topic. Thus, ... -
Feasibility Study to Install a 1 MW Grid Connected Solar Plant in Wairoa-Mahia Peninsular, New Zealand
(IEEE, 2019)This study intends to investigate the voltage drop issue along the Mahia distribution network (11kV line) and further assess the feasibility of developing a grid tied 1MW solar farm in Wairoa District, New Zealand. The ... -
FGC: an efficient constraint-based frequent set miner
(IEEE, 2007)Despite advances in algorithmic design, association rule mining remains problematic from a performance viewpoint when the size of the underlying transaction database is large. The well-known a priori approach, while reducing ... -
Filtering, smoothing, and prediction using a control-loop spectral factorization method for coloured noise
(John Wiley & Sons, 2012)A method for the linear least-squares estimation of random signals contaminated with random noise is shown that uses a new method of spectral factorization. It is shown that the optimal filter can be written entirely in ... -
Finding a closest match between wi-fi propagation measurements and models
(IEEE, 2015)In a series of papers by Sarkar and his team conducted radio propagation measurements to study the performance of Wi-Fi in terms of received signal strengths (RSS) in an obstructed office block. The goal of this paper is ... -
Finding Faults: A Scoping Study of Fault Diagnostics for Industrial Cyber-physical Systems
(Elsevier BV, 2020)Context: As Industrial Cyber-Physical Systems (ICPS) become more connected and widely-distributed, often operating in safety-critical environments, we require innovative approaches to detect and diagnose the faults that ... -
Finding the envelope and efficient frontier of financial assets
(Science Publications, 2012)Problem statement: One of the problems considered in financial mathematics is finding portfolios of given financial assets that minimize risk for targeted returns. The set of such portfolios is called the envelope of the ... -
Finding the Way to Success in Implementing Lean Construction in an Unfavourable Context
(International Group for Lean Construction (IGLC), 2020)Developing countries are facing sever productivity problems in their construction sectors. Lean Construction has proven to be an effective solution for such situations. However, when it comes to lean implementation, the ... -
Finite-time Flocking Control of a Swarm of Cucker-smale Agents With Collision Avoidance
(IEEE, 2017)This paper considers the application of finite-time control to a Cucker-Smale flocking model of autonomous agents with collision avoidance. A mathematical expression for the upper bound on the flocking time is derived. ... -
First Scientific VLBI Observations Using New Zealand 30 Metre Radio Telescope Wark30m
(IOP Publishing, 2015)We report the results of a successful 24 hour 6.7 GHz VLBI experiment using the 30 meter radio telescope WARK30M near Warkworth, New Zealand, recently converted from a radio telecommunications antenna, and two radio ... -
A Flexible and Pattern Reconfigurable Antenna with Small Dimensions and Simple Layout for Wireless Communication Systems Operating over 1.65–2.51 GHz
This research article proposes a compact frequency and pattern reconfigurable flexible antenna for heterogeneous applications. A triangular monopole antenna with a semicircular stub is made frequency and pattern tunable ... -
Flexible Ink-printable Wideband Log-periodic Dipole Array Antenna for Millimeter-wave Applications
(2018 IEEE 7th Asia-Pacific Conference on Antennas and Propagation, 2018)This paper presents a novel flexible ink-printable log-periodic wideband dipole array (LPDA) antenna for millimeter-wave applications. The antenna is fed by microstrip line through a wideband microstrip-to-coplanar stripline ... -
FlexiNet: Fast and Accurate Vehicle Detection for Autonomous Vehicles
(ACM, 2021)Autonomous vehicle has come to reach on the road; however accurate road perception in real-time is one of the crucial factors towards its success. The greatest challenge in this direction includes occlusion, truncation, ... -
Flexural motion of a semi-infinite floating plate under localised edge loading
(New Zealand Mathematical Society (nzmathsoc.org.nz), 2010)Numerical computation of flexural motion of a floating elastic plate is often complicated. The linear approximation of the motion makes the computation tractable for simple harmonic waves in a plate. I will introduce a few ... -
