The authors investigated spatial, temporal, and attentional manipulations in a short-term repetition priming paradigm. Brief primes produced a strong preference to choose the primed alternative, whereas long primes had the opposite effect. However, a 2nd brief presentation of a long prime produced a preference for the primed word despite the long total prime duration. These surprising results a...

IGBT (insulated-gate bipolar transistors) deadtime compensation circuit has a very important significant for improving the output voltage waveform of the inverter, reducing the harmonic output current. Thus, many compensation strategies are reported in literatures and have been implemented in industrial drives recently. Overall, the method of dead-time compensation can be divided into hardware ...

PURPOSE We improved the visibility of the lamina cribrosa (LC), including its posterior boundary, in optical coherence tomography (OCT) images of the human optic nerve head (ONH). METHODS An adaptive compensation algorithm was developed to overcome a limitation of our standard compensation algorithm, that is the overamplification of noise at high depth. Such limitation currently hampers our a...

This paper presents a complete video codec which supports both block-based and mesh-based motion compensation modes. While the mesh-based modes are suitable for spatially continuous representation of in-plane rotations, zooms, and other motions that can be represented by parametric mappings; the block-based modes (especially overlapped block matching) perform better around motion boundaries. Th...

In this reply, I address four general issues raised in the commentaries. Specifically, I attempt to (a) clarify the nature of immediate-return needs, (b) provide more detail on the mechanisms through which frustration of immediate-return needs makes one susceptible to the effects of social motives, (c) address in more detail the relation between I–D compensation theory and other theoretical con...

Control of systems where the information between the controller, actuator, and sensor can be lost or delayed can be challenging with respect to stability and performance. One way to overcome the resulting problems is the use of prediction based compensation schemes. Instead of a single input, a sequence of (predicted) future controls is submitted and implemented at the actuator. If suitable, so...
