Regarding Periodic Phenomena

Misconceptions Regarding Emergent Phenomena Vary By Domain

Although the study of how learners approach emergent phenomena is relatively new, a consistent set of misconceptions associated with emergence have been documented. However, little consideration has been given as to whether some misconceptions manifest more frequently in one domain than another, or take on a different character depending on the agents or phenomenon involved. We examined partici...

Predicting Periodic Phenomena with Self-Organising Maps

Self-Organising Maps are a form of neural network allowing unsupervised learning. In this work, we use a 2-dimensional network. Given a set of data, the neural network learns the distribution of data points, and provides a mapping from the set of data points to the neural network. The mapping has the property that similar data points map to nearby neurons in the network. Figure 2. Self-Organisi...

Periodic cycles of hesitation phenomena in spontaneous speech

To verify whether hesitation phenomena are distributed periodically in spontaneous speech, twenty speech samples produced by five male adults were analyzed. Spectral analysis allowed for three main findings. First, hesitations present stationary behavior, which implies they did not accumulate in the beginning, in the middle, or in the end of speech samples. Second, periodic cycles of hesitation...

Periodic phenomena in Proteus mirabilis swarm colony development.

Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus consolidation phases. Each Proteus swa...
