Integration of radar systems as primary sensor with deep learning algorithms in driver assist systems is still limited. Its implementation would greatly help in continuous monitoring of visual blind spots from incoming pedestrians. Hence, this study proposes a single-input single-output based Doppler radar and long short-term memory (LSTM) neural network for pedestrian detection. The radar is placed in monostatic configuration at an angle of 45 degree from line of sight. Continuous wave with fre...

Abstract Energy conservation measures (ECM) through awareness, good housekeeping measures and demand side management are the first step that must be implemented to achieve energy savings in any building. The energy savings from the implemented ECM must be properly quantified to demonstrate its effectiveness and success.Quantifying energy savings using Multiple Linear Regression (MLR) model have been gaining popularity due to its simple approach but its inability to model and predict dynamic beha...

This study investigates the potential gait features that are related to human recognition using orthogonal least square (OLS). Firstly, video of 30 subjects walking in oblique view was recorded using Kinect. Next, all 20 skeleton joints in 3D space were extracted and further selected using OLS. Additionally, SVM with linear, polynomial and radial basis function (RBF) kernel was used to classify the selected features. As consequences, OLS was proven to be able to identify the significant features...

Narrowing of coronary arteries caused by cholesterol deposits deprives heart tissues of oxygen. In prolonged conditions, these will result in myocardium infarction. The presence of damage tissues modifies the normal sinus rhythm and this can be detected using electrocardiogram (ECG). Hence, this paper characterized history of myocardial infarction from survivors using QRS power ratio features from the ECG. Subsequent profiling is performed using multilayered perceptron (MLP) and hybrid multilaye...

The system identification involves the preprocessing technique which separates the dataset into two parts; training set and testing set to estimate and validate the model respectively. The main aim of this study is to investigate the effects of pre-processing techniques on the steam temperature of the distillation column. Magnitude scaling, block division and interleaving methods were implemented for steam temperature. Two perturbation input signals, of Pseudo Random Binary Signal (PRBS) and Mul...

Face verification focuses on the task of determining whether two face images belong to the same identity or not. For unrestricted faces in the wild, this is a very challenging task. Besides significant degradation due to images that have large variations in pose, illumination, expression, aging, and occlusions, it also suffers from large-scale ever-expanding data needed to perform one-to-many recognition task. In this paper, we propose a face verification method by learning face similarities usi...

In this study the overview of human gait analysis and recognition is discussed based on method and approach by previous researches specifically using the kinect sensor. It was found that upon extraction of the twenty skeleton points using kinect sensor, most researches investigated and explored suitable method or approach in identifying significant gait features for better recognition rate. The advantages and limitation of each study by previous researchers are discussed in detail. However, ther...
