11:50 AM | Dagli equilibri di Nash ai comportamenti collettivi
Quando ho condiviso il tweet qui sotto, non mi ero reso ancora conto del nome che avevo appena letto, eppure avrebbe dovuto suonarmi un campanello nella testa. Continuano i riconoscimenti internazionali per la #matematica dell'Universita' della #Calabria pic.twitter.com/JHIWaVlVGu— Gianluigi Filippelli (@ulaulaman) August 18, 2014Poi dopo è successo che sono andato a ricontrollare (che poi i campanelli magari suonano e semplicemente la suoneria è così bassa che non la […]

8:25 AM | Self-powered micropumps respond to glucose levels
Researchers have demonstrated an active glucose-responsive self-powered fluidic pump based on transesterification reaction of acyclic diol boronate with glucose. The scientific principle of the project is to use well-known glucose/boronate chemistry to design a self-powered micropump device. Instead of synthesizing some new molecules with glucose/boronate reaction, a miniature pump utilizes the energy of this chemical reaction and pumps drugs when glucose levels are high.

2:02 AM | More Tensor Index Identity Proofs: EM II Notes 2014_08_18
Summary:  Having worked through the examples that looked the most difficult, today's notes contain examples that are pick-up work from the easy problems.  These are simple-ish tensor index identities, including the divergence of the position vector, the cross product of the position vector, the Laplacian of one over the displacement squared, and the curl of a gradient.$\nabla \cdot \vec{r} = 3$$= \dfrac{\partial}{\partial x_i} r_i$Keep in mind that $r_1 = x$, $r_2 = y$, and $r_3 = z$.

1:33 AM | Slow Magnet Cooling Hose Hookup: Lab Book 2014_08_18
I’m working on attaching the cooling hoses to the iron yoke magnet today.  I attached the outlet hoses and ran a quick test to make sure that I did indeed have the outlet hose connections.  I attached a water bottle on a hose to the open connection pointed at in the picture below and forced water through.  The water exited at the labeled water out connection.  The exit connection will ultimately have a green hose on it like the manifold on the left.  Do not […]

12:15 AM | Engineering, lego and line followers
In the last few weeks I've been working with some second-year software engineering students on a design project. Their particular task is to build (with Lego - but the high-tech variety) a robot that can follow a white line on a bench. It's fun to watch them play with different ideas and concepts - there's the occasional disaster when the robot roars off at high speed in an unexpected direction and falls off the bench top.  To produce something that approximately works isn't that […]
