EEG emotion recognition using reduced channel wavelet entropy and average wavelet coefficient features with normal Mutual Information method

© 2017 IEEE. Recognizing emotion from EEG signals is a complicated task that requires complex features and a substantial number of EEG channels. Simple algorithms to analyse the feature and reduce the EEG channel number will give an indispensable advantages. Therefore, this study explores a combination of wavelet entropy and average wavelet coefficient (WEAVE) as a potential EEG-emotion feature to classify valence and arousal emotions with the advantage of the ability to identify the occurrence of a pattern while at the same time identify the shape of a pattern in EEG emotion signal. The complexity of the feature was reduced using the Normalized Mutual Information (NMI) method to obtain a reduced number of channels. Classification with the WEAVE feature achieved 76.8% accuracy for valence and 74.3% for arousal emotion, respectively. The analysis with NMI shows that the WEAVE feature has linear characteristics and offers possibilities to reduce the EEG channels to a certain number. Further analysis also reveals that detection of valence emotion with reduced EEG channels has a different combination of EEG channels compared to arousal emotion

Oxygen Hyperbaric Therapy in Patients with Radiation Proctitis

Background: Cervical cancer is the most common female Malignancy in developing countries, including Indonesia. It usually occurs at the age of 20 years, reaches the peak incidence at the age of 35-55 years, and afterwards, the incidence declines. Radiotherapy is the most important treatment method in cervical cancer, especially for local advanced stage or stage IIb-IVa. It is also effective for the early stage. Oxygen hyperbaric therapy (OHBT) is defined as 100% oxygen (O2) administration of 2-3 ATA (Absolute Atmospheres) pressures in a high-pressure room. OHBT accelerates wound healing by improving oxygen perfusion around the wound and by increasing angiogenesis through Nitric Oxide Synthetase (NOS). Methods: The study was conducted at Cipto Mangunkusumo hospital, while OHBT was provided at Dr. Mintoharjo Navy Hospital. Block randomization was performed, Resulting 32 patients in OHBT group and 33 patients in control group; both groups were at normal distribution. The prevalence of radiation proctitis in OHBT and control group was determined using chi-square test. Results: By comparing the prevalence of radiation proctitis between OHBT and the control group, show that OHBT could decrease proctitis prevalence by p = 0.03. Conclusions: This study indicates that OHBT may reduce the prevalence of radiation proctitis. The OHBT is save and secure to the patients

Investigation of window size in classification of EEG-emotion signal with wavelet entropy and support vector machine

© 2015 IEEE. When dealing with patients with psychological or emotional symptoms, medical practitioners are often faced with the problem of objectively recognizing their patients' emotional state. In this paper, we approach this problem using a computer program that automatically extracts emotions from EEG signals. We extend the finding of Koelstra et. al [IEEE trans. affective comput., vol. 3, no. 1, pp. 18-31, 2012] using the same dataset (i.e. the DEAP: dataset for emotion analysis using electroencephalogram, physiological and video signals), where we observed that the accuracy can be further improved using wavelet features extracted from shorter time segments. More precisely, we achieved accuracy of 65% for both valence and arousal using the wavelet entropy of 3 to 12 seconds signal segments. This improvement in accuracy entails an important discovery that information on emotions contained in the EEG signal may be better described in term of wavelets and in shorter time segments

Optimum Rotation for Harvesting of Cajuput Leave at KPH YOGYAKARTA

The productivity of cajuput plantation has improved through tree breeding, while manipulation of site and management engineering of timber plantations have been less attention. Management engineering can be obtained by determining the optimum cycle of cajuput leaves harvesting. This study aims to determine the optimum cycling of cajuput leaves harvesting at KPH Yogyakarta by considering the biological cycles of cajuput leaves, chemical physical properties, and the yield of cajuput oil. The tools used in the research were digital scales, distillation devices, and testing tools of physical-chemical properties of cajuput oil. The material for research was the cajuput plants at KPH Yogyakarta. Data of cajuput leave-twig biomass were obtained for 9 months from 9 plots which were well distributed on various ages. Biological cycle analysis uses curent monthly increment (CMI) and mean monthly increment (MMI) intersection approach. Analysis of the physical-chemical properties on cajuput oil refers to SNI 3954:2014 on cajuput oil. The results showed that the biological cycles of cajuput leaves were obtained 5 months after leaves harvesting. The chemical physical properties of cajuput oil that meet the requirements of SNI were achieved after the leaves are 7 months after harvested. The yield of cajuput oil which is above 0.7% was obtained after the leaves are 8 months after harvested. Thus, the optimum cycle for harvesting of cajuput leaves in KPH Yogyakarta is after 8 months
