    , emotion and saliva hormone. Each participant was testing in red and blue room. Participant was measure the EEG, ECG, SpO2, pulse rate, saliva hormone (melatonin, cortisol, testosterone, progesterone, estradiol and DHEAS), and emotion. The results showed... that red room regulates the tension, anger, vigor and confusion moods which stimulate significant increasing of the pulse rate and SpO2 and cortisol levels but blue room regulates the depression and fatigue. The brain activity of high beta wave (25-30 Hz

    Room occupancy detection using modified stacking
    (2017-02-24) Pawalai Kraipeerapun; Somkid Amornsamankur; Ramkhamhaeng University; Mahidol University
    © 2017 ACM. Occupancy detection is a binary classification task. However, in this paper, stacking for multiclass classification is applied to detect occupancy of a room. Neural network with duo outputs are combined with stacking. The outputs

    (at frontal lobes and temporal lobes) in red and yellow colored rooms were higher than blue, green, white and black colored rooms, respectively. It also had the relationship with the psychological effect (BRUMS). The amplitude asymmetry of beta wave (12-25 Hz...) was highly attenuated in warm color (red and yellow colored rooms), moderately attenuated in cool color (green and blue colored room) and little attenuated in white and black colored rooms. The BRUMS showed that red and yellow yielded significant effect

    © 2015 Published by Elsevier Ltd. The purpose of the present work was to determine the thermal comfort in university building in Thailand under air condition room. The students were tested in 8x9x3 m3test room set up with a 40,000 Btu/h, 2 unit... split type air conditioner. The room air temperature was varied from 25, 26, 27 and 28°C and in each temperature, was varied air speed 3 levels (low, medium and high). Thermal comfort survey using questionnaire base on ASHRAE thermal sensation scale

    Multiperspective analysis of the sisyphus-I room allocation task modelled in a CG Meta-Representation language
    (1999-01-01) Thanwadee Thanitsukkam; Anthony Finkelstein; Mahidol University; UCL
    provide a strong foundation for this purpose. This paper presents the applicability of ViewPoints together with a CG meta-representation language for the knowledge acquisition activities of the Sisyphus-I room allocation task. The paper provides... an illustrative case study of our ongoing work on CG application to the area of software engineering [2]. Although the Sisyphus-I room allocation task is not a natural fit with the ViewPoints framework which aims at different tasks, we have made an attempt
