Abstract Reliability and safety are very critical in complex engineering systems such as chemical nuclear industries. Fault tree analysis (FTA) has been widely applied to evaluate the reliability of systems. This approach assumes that always have exact component failure probabilities. However, this assumption is not true real‐world applications. To deal with this, a number scholars integrated fuzzy into FTA whose probabilities cannot be collected. Furthermore, simple arithmetic operations on...

Abstract Dose verification needs to be carried out on pre-treatment get dose characteristics when using Intensity Modulated Radiotherapy (IMRT) technique. One of the dosimetry tools is 2D-array ionization chamber detectors which gives measurement result in real-time, and does not require periodic calibration. However, this tool has limited spatial resolution, it depends size shape detector, its affected by secondary electron transport from detector wall volume. These factors may lead low...

Pneumonia is a type of diseases in the lungs or respiratory system where alveoli become inflamed and are accompanied by an accumulation fluid. Examination this disease usually done clinically can also be through diagnosis results reading x-rays. Normal lung conditions pneumonia detected identified from digital x-ray images supervised learning classification method. The stage before identification pre-processing process which consists gray scaling, histogram equalization, filtering....

Methods for extracting features of motor imagery from 1-channel bipolar EEG were evaluated. The power spectrums which used as feature vectors calculated with filter bank, FFT and AR model, then classified by linear discriminant analysis (LDA) to discriminate resting states. It was shown that the extraction method using model gave best result average true positive rate 83% (σ = 7%). Furthermore, when principal component (PCA) applied vectors, dimension could be reduced without decreasing...
