"Diabetes is one of the
most serious health challenges in both developed and developing countries. Early detection and accurate diagnosis of
diabetes can reduce the risk of complications. In recent years, the use of machine learning in predicting disease has
gradually increased. A promising classification technique in machine
learning is the use of support vector machines in combination with radial basis
function kernels (SVM-RBF). In this study, we used SVM-RBF to predict diabetes.
The study used a Pima Indian diabetes dataset from the University of
California, Irvine (UCI) Machine Learning Repository. The subjects were female and
≥ 21 years
of age at the time of the index examination. Our experiment design used 10-fold
cross-validation. Confusion matrix and ROC were used to calculate performance
evaluation. Based on the experimental results, the study demonstrated that SVM-RBF
shows promise in aiding diagnosis of Pima Indian diabetes disease in the early
stage."

"Cylindrical uranium dioxide pellets, which are the main components for nuclear fuel elements in light water reactors, should have a high density profile, a uniform shape, and a minimum standard quality for their safe use as a reactor fuel component. The quality of green pellets is conventionally monitored by laboratory measurement of the physical pellet characteristics; however, this conventional classification method shows some drawbacks, such as difficult usage, low accuracy, and high time consumption. In addition, the method does not address the non-linearity and complexity of the relationship between pellet quality variables and pellet quality. This paper presents the development and application of a modified Radial Basis Function neural network (RBF NN) as an automatic classification system for green pellet quality. The weight initialization of the neural networks in this modified RBF NN is calculated through an orthogonal least squared method, and in conjunction with the use of a sigmoid activation function on its output neurons. Experimental data confirm that the developed modified RBF NN shows higher recognition capability when compared with that of the conventional RBF NNs. Further experimental results show that optimizing the quality classification problem space through eigen decomposition method provides a higher recognition rate with up to 98% accuracy."

"Facial detection is a crucial stage in the facial recognition process. Misclassification during the facial detection process will impact recognition
results. In this research, windowing system facial detection using the Gabor
kernel filter and the fast Fourier transform was proposed. The training set
images, for both facial and non-facial images, were processed to obtain the
local features by using the Gabor kernel filter and the fast Fourier transform.
The local features were measured using probabilistic learning vector
quantization. In this process, facial and non-facial features were classified
using label 1 and -1. The proposed method was evaluated using facial and non-facial image testing sets, which
were taken from the MIT+CMU image database. The
testing images were enhanced first before the detection process using four
different enhancement methods: histogram equalization, adaptive histogram equalization,
contrast limited adaptive histogram equalization, and the single-scale retinex
method. The detection results demonstrated that the highest average accuracy
was 83.44%."

"To
develop seismic design criteria for buildings, seismic hazard analysis is required to estimate the ground motion
intensity with criteria such as peak ground
acceleration (PGA). The seismic hazard can be analyzed by using two approaches: deterministic seismic hazard analysis (DSHA) and
probabilistic seismic hazard analysis (PSHA). In these two approaches, the
seismic hazard is evaluated from past earthquake events and active faults data. In Thailand, seismic hazard is classified in the low lying regions; however, in recently years,
earthquakes have occurred frequently in the North of Thailand. To
prevent and reduce damage due to earthquakes in the future, determination
of seismic hazard is needed. This
research proposes a deterministic seismic hazard
map evaluated from nineteen
active faults affecting
Thailand. Two types of active faults are considered: first, an active fault in a subduction zone and second, a crustal fault. The seismic hazard is evaluated by using a ground
motion prediction equation (GMPEs). Four GMPEs are weighted equally for
seismic crustal fault, and two GMPEs are weighted equally for
a seismic subduction zone. The hypocentral distance is
used to evaluate the seismic hazard for all ground motion prediction equations.
The Northern part and the Western part of Thailand are high seismic hazard
regions, because there are active faults with the large possibility of earthquakes of a maximum magnitude. The seismic
hazards in the North, West and Northeast of Thailand are about 0.60 g.
The seismic hazard in Bangkok is about 0.25 g due to the Three Pagoda fault and Sri Sawat fault. The seismic hazard in the South of Thailand is about 0.40 g."

"The antimicrobial properties of bagasse paper sheets coated with
natural polymers (chitosan, different ratios of (gelatin/glycerol) + chitosan,
hemicellulose, hemicellulose + glycerol, hemicellulose+chitosan) or
synthetic organophosphorus dimer compounds were evaluated in this work.
Hemicelluloses showed moderate activity against Bacillus subtilis and Candida albicans, while chitosan showed weak
activity against B. subtilis. The condition that offered the highest inhibitory
activity of bagasse paper was the one
coated with 1,3-diaryl-2,2,2,4,4,4-hexachlorocyclodiphosph(V)azane
(where aryl is p-chloroaniline or p-anisidine). The developed bagasse papers
were evaluated against Gram-positive bacteria, Gram-negative bacteria, yeasts, and fungi. The highest inhibitory activity was obtained at a concentration of 200
mg/mL for p-chloroaniline with an inhibition zone that varied for different
microbes from 6.9 mm to 26 mm. The highest inhibitory activity was obtained at
300?250 mg/mL for p-anisidine against most of the pathogenic microorganisms
with an inhibition zone that varied for different microbes from 8 mm to 14.75
mm. The observed antimicrobial and antifungal activity properties for bagasse paper coated with 1,3-diaryl
2,2,2,4,4,4-hexachlorocyclodiphosph(V)azane could be attributed to the presence of Cl, P atoms, and the lone pair of
electrons on N atoms in the structure of the dimers."

"The routine daily
activities that tend to be sedentary and repetitive may cause severe health
problems. This issue has encouraged researchers to design a system to detect
and record people activities in real time and thus encourage them to do more
physical exercise. By utilizing sensors embedded in a smartphone, many research
studies have been conducted to try to recognize user activity. The most common
sensors used for this purpose are accelerometers and gyroscopes; however, we
found out that a gravity sensor has significant potential to be utilized as
well. In this paper, we propose a novel method to recognize activities using
the combination of an accelerometer and gravity sensor. We design a simple
hierarchical system with the purpose of developing a more energy efficient
application to be implemented in smartphones. We achieved an average of 95% for
the activity recognition accuracy, and we also succeed at proving that our work
is more energy efficient compared to other works."
