متن کاملTaking A Peek Inside The Turtle’s Shell
This paper considers two issues. Firstly it examines the efficacy of a mechanical trading model freely available from the ‘Turtletrader’ web page on the Internet. The results are tested against the Efficient Market Hypothesis (EMH) Weak-Form as proposed by Fama (1970). The findings show that EMH Weak-Form fails to describe the profits generated by the model when examining CBOT Corn and T-Bond f...
متن کاملAnalysis of the Growth of the Nova Scotia Blanding’s Turtle
We have determined that the different plastral scutes (rigid sectional plates found on the plastron, the flat shell structure of a turtle’s ”belly”) of Blanding’s turtle grow at different rates, while scute pairs grow homogeneously. Scute width was used as a new growth measurement to model the growth curve of Blanding’s turtle by fitting exponential and polynomial models. We discovered that the...
متن کاملHodograph Turtles
In classical turtle graphics a line is drawn to connect the turtle’s position vector before and after executing each FORWARD command. A hodograph turtle shadows the classical turtle and draws a line connecting the classical turtle’s direction vector before and after executing each TURN command. Here we study examples of the hodograph turtle in action along with several extensions. We show that ...
متن کاملTurtles for Tessellations
We developed an approach to creating vector graphics representations of tessellations for purposes of teaching creative programming and laser cutting. The approach is based on turtle graphics. The lines of the turtle’s trail define the tiles of the tessellation. The turtle is defined in an object-oriented style and embedded in the Processing environment as a library. The library is called Oogwa...
