Google's Food Detection Algorithm is Not Bad

I was scrolling through Google photos when I noticed they had auto-categorized some of my pictures. Overall I have to say their algorithm was not too bad. It was able to recognize (from left to right) a watermelon, a microscope picture of a strawberry and a microscope picture of homemade bread. Taken with my smartphone microscope of course.

It trips up a bit when it gets to what the majority of my photos contain ... bike horns. These particular images show me digitally marking up an early 3D printed horn prototype to communicate design changes to Chris, the industrial designer for Loud Bicycle.

While we are on the topic, please check out the Kickstarter for the new bike horn that will be even better than the last horn. As of this posting we have not yet reached the goal, so please support it!

And for that I present what I think is the very first animated GIF in LanseyBrothers Blog history.

Seriously though, have we ever had an animate gif before?

national grid has no idea who we are

National Grid has absolutely no idea who we are, so they addressed the envelope to "Or Current Resident"

A new paper

I just had a paper, "Measurement of Photon Sorting at Microwave Frequencies in a Cavity Array Metasurface" (based on some of my dissertation work, believe it or not) published in IEEE Transactions on Antennas and Propagation. It was a ridiculous review process and I owe many thanks to Isroel Mandel for his efforts getting this darn thing published. This is not an open-access paper, so let me know if you want a copy.

The basic idea in this paper is an experimental extension of previous results. In the previous paper, we demonstrated in simulation how electromagnetic fields are spectrally and spatially split into different regions of a metamaterial structure. In this paper we report how we measured this field splitting:
We also demonstrated how this method might be expanded to include three different, distinct absorption frequencies.

For the rest of the info, read the paper!

Don't believe everything you read on the internet

We finally have the real Abraham Lincoln that is credited with that famous quote
Don't believe everything you read on the internet just because there's a picture with a quote next to it. –Abraham Lincoln  
Thanks for the glasses.

file exchange pick of the week

After five years up on MatlabCentral, my little script to plot histograms has been selected as a "pick of the week" by Mathworks. Pretty cool - I'm even getting a free T-Shirt. The best part is that I finally have something to show Eli that Matlab appreciates me as much as Mathematica appreciates him. Next time I hope they take a look at my beautiful line colors submission to matlabcentral so they can choose something besides this random green color :P

Thanks Matlab!!

Another pedantic letter to the editor

Last week this article was published in the Teaneck Suburbanite, with the following lines (emphasis added):
Trains carrying Bakken crude oil from North Dakota travel through Teaneck and other Bergen County towns regularly before arriving at a refinery in Philadelphia. Their numbers have increased exponentially in the past few years, and several derailments have occurred in Canada and across the United States.
Well, I felt the need to respond, and this week they printed my letter to the editor:
To the editor,
A recent article about the freight trains carrying Bakken crude oil running through Teaneck ("Resolution for trains to stop idling passes", Sept. 17, 2015) claimed that "[t]heir numbers have increased exponentially in the past few years..." This is not correct. "Exponentially" is not a more dramatic way of saying "rapidly" -- it means "at a rate proportional to the current value".
According to data from the U.S. Energy Information Administration (, crude oil traveling by rail from the midwest (i.e. North Dakota) to the northeast (i.e. Teaneck) has increased roughly linearly since 2012, at a rate around 4.3 million barrels per year (see:, which corresponds to approximately 6,000 extra tanker cars per year.
While the (linear) rate of increasing oil traffic may still be very concerning to residents, like myself, who live within the "danger zone" of the tracks, we should, at the very least, be accurate in our descriptions of the situation.
