Plotly Example

Plots should see a plot here Code could not finish, some reasons why this could happen: - Plot name not defined. The first parameter of the shortcode is the name. - There is a syntax error. check browser console. Second Plot and another here table Animal Sound Cat Meow Dog Woof String status = [1 1 1 0 0 1 1] x = [1 2 3 4 5 6 7] y = [2 4 6 8 16 32 64] z = [2 4 6 16 16 30 50]

100 Year Flood

Definition

100-year flood, means that the Annual Exceedance Probability is 1/100.

It is a strange term. I cannot think of any other probability that is expressed in this way. In any case, I want to calculate the 100-year flood plain for my area.

Movie Narrative Chart

Comic There is a great xkcd about plotting the relationships of characters in a movie. I find it a very elegant way to present information that is otherwise a complicated network of changing relationships. Primer Of course, the punchline is the movie Primer which involves a substantial amount of time travel. It’s just a bunch of scribbles. Ha Ha. Back when I first watched the movie (2011?), I stumbled upon this chart explaining the timelines.

TravelMap

travels I wanted to make a digital version of one of large maps where you put actual pins to show where you’ve been. Basemap makes that pretty easy. My code is on GitHub: travelmap.py Here is what the Raw data looks like: Year State/Country Trip/Path Latitude Longitude 1987 Illinois Home 41.439691 -88.949886 1990 Wisconsin Dells 43.627705 -89.773422 1997 Wisconsin I90 43.51265 -89.530689 2014 Montana Bozeman 45.713946 -111.068216 2015 Brazil Rio De Jenaro -22.

Recurrent Neural Network

After watching this presentation, where Martin Görner shows the use of recurrent neural networks to create a new Shakespeare play, I was feeling inspired. So, I pointed his code a bunch of song lyrics. Background I’ve been interested in Neural Networks for a long time because, fundamentally, they are similar to a process controller. $$ Output = Input \times Weight + Bias $$ It’s just a line. For multiple inputs/outputs, the equation is the same, but they are matrices (or tensors).

Temperature Control

Problem: stove-top temperature is poorly controlled resulting in inconsistent cooking times and results.

Solution: Use an Arduino to control the temperature of pan.

Toilets

I thought it would be fun to talk about toilets since we interact with them daily, yet, mostly ignore them and their operation. Components: water inlet diaphragm valve Tank open to atmosphere (usually covered) Level Indicator with mechanical linkage to diaphragm valve(2) Chain operated stop-check valve Bowl also open to atmosphere S-bend outlet pipe to sewer/septic system Operation During normal operation, the water level in the tank is controlled by feedback from the level indicator to the inlet valve.
