Prioritisation of candidate genes and single nucleotide polymorphisms for dental caries susceptibility
Discovery of causal genes and awareness of risk factors for dental caries may assist development of personalised prevention and early detection of dental caries. A computational approach to identify and prioritise candidate genes and single nucleotide polymorphisms (SNPs) was developed and applied to dental caries susceptibility. Information on normal biological functions from gene ontology (GO...


ANN-based EMG classification for myoelectric control
This work presents a new neural network model related to EMG signal classification for myoelectric control. The aim of this work is to develop a more accurate method for pattern recognition and intention interpretation of five human forearm hand gestures: grasping, extension/flexion, and ulna/radial deviation. A sum of 750 signals that incorporated all the selected hand movements were acquired ...
A preliminary comparison of using handheld devices in promoting the healthcare performance within a radiology department in terms of diagnostic accuracy and workflow efficiency
A preliminary research was conducted to compare the merits of using smartphones, iPad, and other tablet handheld devices with traditional systems in enhancing performance and workflow of radiology department. Review of work done on the topic was used as the secondary research method. There were not many works directly related to the topic. Hence, other related works were also reviewed. Neverthe...


Closed-loop control strategy for type I diabetic patients
Administering 'optimal' amount of insulin to maintain the blood glucose (BG) concentration in the normoglycaemic range is vital in type I diabetics. Insulin injection therapy is widely practiced for the maintenance of blood glucose levels within the normoglycemic range (70-100 mg/dL) for type I diabetics. Current insulin therapy for patients with type I diabetes often results in high variabilit...
A neuro-fuzzy decision support model for therapy of heart failure
Most medical decision support systems focus on diagnosis with little emphasis on therapy to the effect that though an accurate diagnosis is undertaken patients still have problems of drug misuse as a result of inaccurate therapy. The purpose of this paper is to design an assistive model for therapy of heart failure using artificial neural networks (ANN). Artificial neural networks have been fou...


Adapting rough-fuzzy classifier to solve class imbalance problem in heart disease prediction using FCM
The main objective of this research is to develop a heart disease prediction technique by solving class imbalance problem. Class imbalance problem severely affects the performance of the prediction if the distribution of data is not clearly defined. To overcome class imbalance problem and achieve promising results in this work, the proposed technique is divided into three steps. Initially, the ...
Implementation of motion transfer in robotic surgery
Minimally invasive surgery is a modern surgical technique in which the operating tools are inserted into the patient through small incisions. Robotic applications in general surgery have evolved from simple surgical assist devices, to more sophisticated systems capable of enhancing surgical performance. The primary class of robots used in general surgery today, are 'master-slave' machines, wher...

Buckling analysis of thin-walled sections under localised loading using the semi-analytical finite strip method
Thin-walled sections under localised loading may lead to web crippling of the sections. This paper develops the Semi-Analytical Finite Strip Method (SAFSM) for thin-walled sections subject to localised loading to investigate web crippling phenomena. The method is benchmarked against analytical solutions, Finite Element Method (FEM) solutions, as well as Spline Finite Strip Method (SFSM) solutio...
Indentation of sandwiches using a plate model with variable kinematics and fixed degrees of freedom
A recent 3-D, 5 degrees of freedom, variable kinematics zig-zag homogenised model is used for studying sandwich indentation. This model cannot describe in a point-wise sense cells collapse, buckling, debonding failure, plastic yielding, or brittle fracture. Therefore, the progressive folding followed by densification of the core is described through mechanical properties variable with loading, ...

A methodological paradigm for patient-specific multi-scale CFD simulations: from clinical measurements to parameter estimates for individual analysis
A new framework for estimation of lumped (for instance, Windkessel) models parameters from uncertain clinical measurements is presented. The ultimate aim is to perform patient-specific haemodynamic analysis. This framework is based on sensitivity analysistools and the sequential estimation approach of the Unscented Kalman Filter. Sensitivity analysis and parameter estimation are performed in lu...
An investigation of stimulation mechanisms in Enhanced Geothermal Systems
We review ten historical Enhanced Geothermal Systems (EGS) projects and find that typically, during injection: (1) flow from the wellbore is from preexisting fractures, bottomhole pressure exceeds the minimum principal stress, and pressure-limiting behavior occurs. These observations are apparently contradictory because (1) is consistent with shear stimulation, but and suggest propagation of ne...

Nonlinear nonlocal analysis of electrostatic nanoactuators
This study investigates the small scale effect on the nonlinear static and dynamic response of a capacitive nanoactuator subjected to a DC voltage. The nanoactuator is modeled as a Euler–Bernoulli beam cantilever beam and beam clamped at its both ends. The model accounts for residual stresses, initial deflection, the von Kármán nonlinear strains, and the electrostatic forcing. The intermole...
Smart cure cycle for reducing the thermal residual stress of a co-cured E-glass/carbon/epoxy composite structure for a vanadium redox flow battery
The vanadium redox flow battery (VRFB) is considered as one of the most promising energy storage system in the future. It is composed of two endplates and a stack which consists of flow frame (FF), electrode, bipolar plate (BP) and membrane. Because the electrolytes flowing in the stack are sulfuric-acid-based solutions, prevention of leakage is important. The unified structure of the FF and th...
Predicting process-induced distortions in composite manufacturing – A pheno-numerical simulation strategy
Process-induced distortions (PID) of high-performance CFRP structures lead to problems with dimensional control if the distortions are not accounted for by compensating the process tool accordingly. There is a need to predict PID via simulation in industry rather than relying on less reliable information such as past experience or measurements on prototype structures. PID are caused by many phe...
