This study examined neural activity with event-related potentials (ERPs) in middle childhood during a computer-simulated ball-toss game, Cyberball. After experiencing fair play initially, children were ultimately excluded by the other players. We focused specifically on “not my turn” events within fair play and rejection events within social exclusion. Dense-array ERPs revealed that rejection e...

This study offers a method for empirically testing theories operationalized in the form of multivariate statistical models. An innovation of the method is that it distinguishes testing into three separate forms, “effect testing,” “prediction testing,” and “theory testing,” where statistical significance plays a separate role in each one. In another innovation, the researcher specifies not only ...

Cloud detection and analysis from satellite images has been a topic of research in many atmospheric and environmental studies; however, it still is a challenging task for many reasons. In this paper, we propose a new method for cloud-type classification using fuzzy logic. Knowing that visible-light images of clouds contain thickness related information, while infrared images haves height-relate...

Signal detection theory (SDT) assumes a division of objective truths or "states of the world" into the nonoverlapping categories of signal and noise. The definition of a signal in many real settings, however, varies with context and over time. In the terminology of fuzzy logic, a real-world signal has a value that falls in a range between unequivocal presence and unequivocal absence. The defini...

One of the key strengths of the region connection calculus (RCC) — its generality — is also one of its most important drawbacks for practical applications. The semantics of all the topological relations of the RCC are based on an interpretation of connection between regions. Because of the manner in which the spatial relations are defined, given a particular interpretation of connection, the RC...

In order to reduce the capacity of active power filter (APF), improve its dynamic tracking speed and anti-disturbance ability harmonic currents, so as better solve problem pollution in medium high voltage distribution network, this article is suitable for networks. The three-phase three-wire injection hybrid (IHAPF) network research object, a fuzzy linear disturbance rejection controller (Fuzzy...

In response to the problems of impedance variation and rich background harmonics in weak grid environment traditional LCL grid-connected inverters, which cause distortion current reduce stability entire system, this paper proposes a passive fuzzy-active disturbance rejection control strategy. Firstly, passivity-based (PBC) is introduced into inverter system ensure global system. Secondly, order...

this study proposes a combination of a fuzzy sliding mode controller (fsmc) with integral-proportion-derivative switching surface based superconducting magnetic energy storage (smes) and pid tuned by a multi-objective optimization algorithm to solve the load frequency control in power systems. the goal of design is to improve the dynamic response of power systems after load demand changes. in t...
