Across the US, plummeting CS enrollments and disappointing student retention have caused serious concern in recent years. Yet, in the Spring of 2007, the Berea College faculty unanimously adopted a CIS major in response to the rise in enrollment in CS0 and retention into CS1. This paper details how using a funnel approach to attract students into the discipline via multiple CS0-level courses resulted in the exception to the trend.
In this paper, we describe our proof of concept system that uses genetic algorithms to generate choreography for the waltz, a ballroom dance. We detail the representation of the dance steps and sequences our system manipulates, and our design of the fitness function to guide the algorithm. Preliminary results show that we have successfully incorporated several rudimentary choreography principles and that our system thus can generate effective waltz sequences. There are many potential areas of future development for our system, such as extending it to generate more sophisticated choreography for a variety of ballroom dances.
In the paper by Stalnov et al. there has been a duplication of Fig. 5a such that it also appears as Fig. 4b. The correct Fig. 4b is shown below with its correct caption.-2 0 2 4 6 8 10 0 0.5 1 1.5 T [sec] Normal. Amplitude HF HW #1 HW #2 Fig. 4b Ensemble averaged (64 realizations) short-time standard deviation (256 time points, at a sampling rate of Fs = 2.5 kHz) of two hot-wires (HW) located in the wake (spanwise distance between the two wires is approximately 5D) and the body-mounted hot-film (HF) shear sensor. At time T = 0 the actuators were turned ON. The input signal to the actuators is amplitude modulation (AM) of a modulation signal from the VCO (at the natural vortex shedding frequency), and a carrier signal of 1.35 kHz. The closed-loop was locked to the hot-film (HF) body-mounted sensor. The amplitudes are normalized by their baseline uncontrolled magnitude The online version of the original article can be forund under
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
