Interactions between prefrontal cortex (PFC) and stimulus-specific visual cortical association areas are hypothesized to mediate visual working memory in behaving monkeys. To clarify the roles for homologous regions in humans, event-related fMRI was used to assess neural activity in PFC and fusiform face area (FFA) of subjects performing a delay-recognition task for faces. In both PFC and FFA, ...

This paper discusses the characteristics of powerfactor-correction (PFC) switching regulators of non-cascading structures in terms of efficiency, input current harmonic distortion, and load transient response. The discussion begins with simplified power flow diagrams of the non-cascading PFC switching regulators and describes their essential features for achieving power factor correction and ti...

The primate prefrontal (PFC) and posterior parietal cortices (PPC) have been shown to be cardinal structures in processing abstract absolute magnitudes, such as numerosity or length. The neuronal representation of quantity relations, however, remained largely elusive. Recent functional imaging studies in humans showed that blood flow changes systematically both in the PFC and the PPC as a funct...

Melt flow in continuous casting tundishes is normal[y characterized by a combined model. The model is used to analyze the residence time disttibution of fluid in a tundish, In this model, the fluid volume in tundish is considered to be consisting of the plug flow, well-mixed flow, and dead volumes. Although this model was proposed over 20 years ago, most researchers have either used it incorrec...

This work provides approaches to designing and fabricating soft fluidic elastomer robots. That is, three viable actuator morphologies composed entirely from soft silicone rubber are explored, and these morphologies are differentiated by their internal channel structure, namely, ribbed, cylindrical, and pleated. Additionally, three distinct casting-based fabrication processes are explored: lamin...

A model of investment casting a titanium alloy gearbox based on the ProCAST software was established in this work, and simulated result used to optimize process. The flow temperature field were an actual pouring Casting defects solidification process analyzed. results show that can be predicted by simulation exactly, is accordance with Shrinkage porosity are observably alleviated remodelling mo...

A nonlinear predictive controller is presented in the paper. The greatest advantage of predictive functional control (PFC) is very fast and easy calculation of control variable. Combined with the Takagi-Sugeno (TS) fuzzy model, the PFC becomes nonlinear and is called fuzzy PFC (FPFC). The controller was evaluated by simulation on the well-known process, the continuous stirred-tank reactor (CSTR...
