“…Table 7 shows the comparison of the average area and latency between the two groups. The smallest average area in Group 1 is the emergent situation induced condition, and its corresponding latency is also the shortest; in Group 2, the shortest latency is seen in the neutral picture induced A verage of the total score condition (Portnova, 2017;Reddy and Suseela, 2017;Feng et al, 2016;Salokyová, 2016).…”

The influence of public opinions on emergency decision-making has attracted more and more attention in recent years. Emergency decision-making is characterized by high risk, fuzzy information and time pressure. Public opinions induced by emergency have important influence on people's decision-making preference. Based on the four induced conditions, including positive public opinion, neutral public opinion, negative public opinion and public opinion induced by emergent situations, this paper studies the brain evoked potential information of subjects and proposes a new intuitive decision-making model. The results show that the average scores of the positive opinion group on the positive scale are significantly different, while the scores of the negative opinion group on the negative scale are significantly different. Participants in group of public opinion induced by emergent situations tend to be more adventurous in their decision-making preferences than those in the negative public opinion group. The results of brain information processing of neutral, positive and negative public opinion groups show that both the standard stimulus and deviant stimulus could induce obvious negative deflection in 100-200ms in EEG. In the processing the information induced by emergent situations, amplitude deviation between the standard stimulus and deviant stimulus is smaller, which is perceived as insensitive.

“…These nonlinear equations are overdetermined and insolvable. However, there is a possible solution by minimizing the sum of squared errors, according to the nonlinear least squares fitting method (Yao et al, 2012;Shi et al, 2016;Cai et al, 2012;Liu et al, 2016;Zhang, 2012;Feng et al, 2016;Cannistraro et al, 2016). Specifically, all the data points in D were fitted with a set of undetermined coefficients,…”

This paper aims to mitigate the negative effect of production data errors on the curve of inflow performance relationship (IPR). To this end, the author proposed a brain-inspired productivity computation method for oil wells based on Shannhan's brain-inspired cognitive architecture. The architecture consists of two interacting sensorimotor loops. In the proposed method, the IPR parameters were fitted in the inner loop, and the fitting results were considered in the productivity computing in the outer loop. Then, the proposed model was applied to compute the oil productivity of a real oil well, compared with other common methods, and verified through numerical simulation. The results show that the new method can predict well productivity more accurately than the contrast methods. Suffice it to say that this research puts forward a simple and reliable method for IPR curve drawing.

“…The main processor (386EX, 8086, SparcV7/V8, etc.) are allocated to execute different taskssequentially with pipeline, by running different processes with the certain priority level to optimize main processor efficiency,so the highly-reliability crystal oscillator is employed.But there are many nonlinear dissipations accompanied by large amplitude oscillation (Feng et al, 2016), therefore primary processor must have spare.Meanwhile, in order to achieve high level of dependability, OBDH hardware is alsobe fault tolerant, redundant in Figure 8.…”

This paper presents the extended dynamic fault tree (eDFT) model for fault-tolerant Onboard Data Handling (OBDH) software used in microsatellite. For high reliability, in case of the primary processor failure, hot/warm spare automatically and uninterruptedly start torun the OBDH software without critical data missing. Memory with triple-modular redundancy and communication bus with spare are frequently employed in OBDH subsytem design. The important feature of OBDH software which is different from hardware lies in software reconfiguration/redundancy. In safe mode, some of OBDH software modules, even the whole software, can be reconfigured. Because of the limitation of traditional fault tree regardless of dynamic redundancy, the eDFT must model this case to evaluate the instantaneous reliability of OBDH software. Time-tofailure tree (TTFT) can be used to implement the conversion of eDFT model. The result shows this approach is much fast and prompt, and the acceleration value is in direct proportion to TTFT units.
