Tailfins on your tires! Newest zoom-go-fast innovation from Japan

The newest innovation from Yokohama Rubber is putting fins on your tire sidewalls. Yokohama Rubber Company has tweaked their tires with fins built into the sidewalls to cut a vehicle’s aerodynamic drag and lift.

Compared to conventional tires (L), new advances (R) reduce vehicle aerodynamic drag and lift—-
fins-on-rubber-tire Press Release | 2015.Oct.15 : Yokohama Rubber Advancing Tire Aerodynamics Tech


According to Yokohama Rubber’s announcement (2015.Oct.15), the new development reduces vehicle aerodynamic drag and lift resulting in increased fuel efficiency and vehicle safety.

Following its successful research on rolling resistance, Yokohama Rubber first found in 2012 that placing fin-shaped protuberances on the inner sidewall of the tire in a radial or spoke-like pattern to reduce the aerodynamic drag inside the wheel wells. This latest development controls aerodynamic flow throughout the vehicle body by using a new fin shape and placement technique that places the fin protuberances at angles near the tire’s shoulder on the tire’s outer sidewall help to reduce vehicle aerodynamic drag when on the upper part of the tire during its rotation while suppressing vehicle aerodynamic lift when on the lower part of the tire.

Shibuya flushes away stained reputation of having filthy toilets
Asahi News Sept. 26, 2015
once derided a restroom in the young people’s fashion district of Harajuku as “the world’s dirtiest,” today it has been cleaned up and transformed into the “Sushi Ninja Toilet.”
The once-filthy toilet was “adopted” by Genco Inc., an anime production companyand its Sushi Ninja character is now plastered on the exteriormore

Question posed on reddit:

I was wondering automation and its effects on the workforce. Given that Hitachi has now introduced the first AI managers. Will automation change “employment” as we know it in the coming years?

My answer:

The AI [artificial intelligence] of those “AI managers” does not mean they are bosses. The so-called “AI managers” are just software schedulers of logistics tasks using some AI. All major shipping companies have been using such software for years—the same for taxi companies, auto parts warehouses, and gambling casino management.

According to Hitachi’s press release (2015-09-15), the company is just trying to smooth out allocation production resources using better scheduling and prediction of factory job orders. These are not robot “managers” bossing humans around—just fancy computer calendars tied into Excel spreadsheets, <yawn>.

By integrating artificial intelligence technology into Hitachi’s automation for logistics tasks, they were able to verify an 8% improvement in efficiency. Cool! However, that’s what, UPS, Walmart, and every supermarket chain has been doing for the past 20 years.

The key point is that Hitachi’s AI technology is trying predict glitches in their production and figure out whether improvements/keizen actually work together to boast production. For example, a 200% improvement in the Widget bolt tightening also must have a 200% improvement in the Widget locking washer placement and picking/fitting of bolts before they’re tightened.

Bottom line: Move along folks—Nothing to see here, yet.

Rocking Rock Lobster!

This morning our Tropical Rock Lobster molted.
Hooray!! *\(^o^)/*
It’s been about 10 months from its last molting and it has grown even larger (^^).
Here’s the lobster shown next to me (I’m 157 cm tall).

The aquarium’s Tropical Rock Lobster (aka Ornate Rock Lobster, Ornate Spiny Lobster or Ornate Tropical Rock Lobster is the Panulirus ornatus (Wiki, see right)) is quite the monster of the deep, isn’t it?
