Moving object detection via TV-L1 optical flow in fall-down videos
There is a growing demand for surveillance systems that can detect fall-down events because of the increased number of surveillance cameras being installed in many public indoor and outdoor locations. Fall-down event detection has been vigorously and extensively researched for safety purposes, particularly to monitor elderly peoples, patients, and toddlers. This computer vision detector has become more affordable with the development of high-speed computer networks and low-cost video cameras. This paper proposes moving object detection method based on human motion analysis for human fall-down events. The method comprises of three parts, which are preprocessing part to reduce image noises, motion detection part by using TV-L1 optical flow algorithm, and performance measure part. The last part will analyze the results of the object detection part in term of the bounding boxes, which are compared with the given ground truth. The proposed method is tested on Fall Down Detection (FDD) dataset and compared with Gunnar-Farneback optical flow by measuring intersection over union (IoU) of the output with respect to the ground truth bounding box. The experimental results show that the proposed method achieves an average IoU of 0.92524

The profile of students' mathematical representation competence, self-confidence, and habits of mind through problem-based learning models
Mathematics is an essential subject for students. Teachers, therefore, need to provide innovative learning that develops students' mathematical skills. This study was conducted to determine the effect of a problem-based learning (PBL) model on students' mathematical representation competencies, self-confidence, and habits of mind. It used a quantitative methodology and was conducted on eighth-grade students divided into an experimental class with a PBL model and a control class with a direct learning model. The results showed that the mathematical representation competencies of the students in the experimental class were better than those in the control class. Students' self-confidence and habits of mind also influenced their mathematical representation competencies. It shows that the PBL model positively affects students' mathematical representation competency, self-confidence, and habits of mind. Teachers can use the PBL model to develop their students' mathematical representation competencies by paying attention to students' self-confidence and habits of mind

Modelling computational thinking with game-based learning among primary school students’
The computational thinking (CT) skills of students will be revised, increasing their future viewpoint in the sphere of scientific activities, notably in education interest. Game-based learning (GBL) appears to have the potential to improve students’ motivation to learn. Students’ GBL is associated with higher mathematics performance, and GBL’s strong relationship with CT may have an even larger effect. The entirety of this CT education research is focused on undergraduate classrooms; little is revealed about how GBL support CT in K-12, particularly in primary schools. This study utilized a Structural Equation Model (SEM) in modelling the relationship between CT and GBL among primary school students. A sample of 90 primary school students from Malaysia was chosen. In this study, the Partial Least Squares-Structural Equation Model (PLS-SEM) was employed to develop the model. The results demonstrate that empirical evidence, coupled with prior observations verified the model developed. The developed model successfully confirmed all the indicator variables stated in the constructs as all of the associations within the model were significant. In conclusion, the lower order components (LOC) along with the hierarchical component model (HCM) in PLS-SEM depicted the relationship between CT and GBL, substantiated empirically
Mapping lung cancer disease in Libya using Standardized Morbidity Ratio, BYM model and mixture model, 2006 to 2011: Bayesian Epidemiological Study
Cancer represents a significant burden on both patients and their families and their societies, especially in developing countries, including Libya. Therefore, the aim of this study was to model the geographical distribution of lung cancer incidence in Libya. The correct choice of a statistical model is a very important step to producing a good map of disease in question. Therefore, in this study will use three models to estimate the relative risk for lung cancer disease, they are initially Standardized Morbidity Ratio, which is the most common statistic used in disease mapping, BYM model, and Mixture model. As an initial step, this study begins by providing a review of all models are proposed, which we then apply to lung cancer data in Libya. In this paper, we show some preliminary results, which are displayed and compared by using maps, tables, graphics and goodness-of-fit, the last measure of displaying the results is common in statistical modelling to compare fitted models. The main general results presented in this study show that the last two models, BYM and Mixture have been demonstrated to overcome the problem of the first model when there no observed lung cancer cases in certain districts. Also, other results show that Mixture model is most robust and gives a better relative risk estimate across compared it with a range of models
A review of automated micro-expression analysis
Micro-expression is a type of facial expression that is manifested for a very short duration. It is difficult to recognize the
expression manually because it involves very subtle facial movements. Such expressions often occur unconsciously, and
therefore are defined as a basis to help identify the real human emotions. Hence, an automated approach to micro-expression
recognition has become a popular research topic of interest recently. Historically, the early researches on automated micro-expression have utilized traditional machine learning methods, while the more recent development has focused on the deep
learning approach. Compared to traditional machine learning, which relies on manual feature processing and requires
the use of formulated rules, deep learning networks produce more accurate micro-expression recognition performances
through an end-to-end methodology, whereby the features of interest were extracted optimally through the training process,
utilizing a large set of data. This paper reviews the developments and trends in micro-expression recognition from the
earlier studies (hand-crafted approach) to the present studies (deep learning approach). Some of the important topics
that will be covered include the detection of micro-expression from short videos, apex frame spotting, micro-expression
recognition as well as performance discussion on the reviewed methods. Furthermore, major limitations that hamper
the development of automated micro-expression recognition systems are also analyzed, followed by recommendations of
possible future research directions
Design of optimal multi-objective-based facts component with proportional-integral-derivative controller using swarm optimization approach
This study proposes a multi-objective-based swarm intelligence method to improve angle stability. An optimization operation with single objective function only improves the performance of one perspective and ignores the other. The combination of two objective functions which derived from real and imaginary components of eigenvalue are able to provide better performance beyond the optimization capabilities of single objective function. Tested using MATLAB, the simulation is performed using a single machine attached to the infinite bus (SMIB) system equipped with static var compensator (SVC) that attached with PID controller (SVC-PID). The objective of this experiment is to explore the excellent parameters in SVC-PID to produce a more stable system. In addition to the comparison of objective functions, this study also compares particle swarm optimization (PSO) capabilities with evolutionary programming (EP) and artificial immune system (AIS) techniques
Mapping Libya’s prostate cancer based on the SMR method: a geographical analysis
Disease mapping has become an important method used in public health research and disease epidemiology. It is a
spatial representation of epidemiology data. A very common disease mapping method is called Standardized
Morbidity Ratio (SMR). Many researchers used this method to estimate the relative risk of the disease as a
preliminary analysis. In this study, the SMR method displays the high and low risk areas of prostate cancer for all
districts in Libya. SMR is the ratio of the observed to the expected number of prostate cancer cases and was applied
to the observed prostate cancer data from Libya for the years 2010 and 2011. The results were presented in graphs
and maps. The highest risk of prostate cancer (all type of cancers) is in the West of Libya probably due to the oil
installations in this area such as Mellitah Oil and Gas B.v, the Azawia Oil Refining Company and Bouri Oil Field, as
well as the electrical power stations. Susceptible people located in the Eastern part of the country have the lowest
risk when compared to the overall population. In conclusion the results show that the use of the SMR method to
estimate the relative risk in maps provides high-low risk appearances in maps compared to using the total number of
cancer incidence alone. In other words, the SMR method can be considered a basic procedure because it takes into
account the total human population for each district
