Beta-rage electroencephalogram (EEG)-EMG coupling has been extensively investigated under different force output tasks of human-machine interaction over the past decades. By applying corticomuscular coherence (CMC), beta-range (15–30hz) coherence has been well investigated during static force condition as well as dynamic force condition. However, the traditional CMC method limits the two different...
In order to understand the current situation of our Chinese residential kitchen and apply the basic data to make the new level as well, investigation and experiment research were carried out. This article, combining the method of subjective and objective, investigates the pollution diffusion, occupants' comfort, etc, and then make a comparative analysis of questionnaire survey and experiment measurement...
The aim of this paper is to estimate muscle fatigue by using wavelet analysis method in SEMG signal analysis. A signal acquisition system is designed and forearm muscle fatigue experiments under static and dynamic contractions are performed. The wavelet analysis method is proposed to group the wavelet coefficients of SEMG signal into high frequency-band (100Hz-350Hz) and low frequency-band (13-22Hz)...
The research analyzes distribution laws of exhaust-gas of burning liquefied-gas in closed kitchen without any kitchen hood or fan with the exergy indicator; and compares the distribution results from the exergy analysis with those from the concentration analysis. The methods are: establish the math models of exhaust-gas exergy and concentration distributions in some boundary conditions; use discrete...
Several new concepts are introduced, such as single satisfaction, synthesis satisfaction and sub-optimal plan. With those concepts a new algorithm based on Graphplan is presented. A lot of restrictions make the Graphplan planner far from the real world. The new algorithm inherits all the capabilities of Graphplan. Except this, it also adapted to other situations. For a problem, if Graphplan can't...
Graphplan [Blum & Furst] has proved a popular and successful basis for a succession of extensions. In this paper, we explore the extent to which its representation can be used for planning with soft resource constraints. We present a new algorithm called fuzzy resource constraints graphplan (FRCGP). In the process of graph expansion, according to the satisfaction degree that the user requires,...
