Profits must be low if they can't get a website hosting company that doesn't have a popup on every page carrying adverts!
And related ... I emailed Arnia for some specifics recently and didn't get a reply. Perhaps their batteries have run out?

Three steps forward, three steps back ....
Experiments for acquisition of the diagnostic information found in vibrational signal.
The 20 hives set up at INRA are also being continuously monitored for health conditions including Varroa destructor infestation (using the icing sugar method), the presence of chalkbrood (Ascosphaera apis) and Nosema ceranae.
In addition regular estimates of the number of bees and amount of brood are being made. Vibration data has been collected for more than 100 days in the form of averaged spectra from the accelerometers.
Principal component analysis (PCA) has been applied to these data and a high level of similarity has been obtained from hive to hive for the healthy colonies.
All but one of the colonies at INRA were lost over the winter of 2013/2014, however, this has provided valuable data showing how the vibrational signals change as a colony is lost.
All colonies that had been lost over the winter were repopulated in advance of the 2014 swarming season.
19/20 hives lost overwinter. Blimey. I wonder how the vibrational signal changes when the colony is 'lost' ...

Yep. They're dead.
That is crap beekeeping at its best an almost total wipe out
Wonder how you apply an accelerometer without being swamped by movements and vibration from wind rain etc
You could easily tell if the hive had been blown over or moved though so thats one element of neglect they had covered
Before they started electronic monitoring they should have taken the Honeybadger Basic Beekeeping course
Ok, maybe I overstated progress! I thought I had read they'd identified common factors in swarming colonies but that may have been wishful thinking and a too quick skim.
19/20 is pretty horrendous and now the swarm monitor website seems to have disappeared, another winter loss ...
I presume that this is just coincidence, the site disappearing as folk here took an interest. Who knows. Anyway, there is more on this project (which came to an end just over a month ago) here. The 19/20 loss was downplayed to 'a number' lost overwinter. Perhaps they've just proved that hive monitors cause CCD?

First apologies to anyone who is bored by computing heres a little link for you

For those folk who fancy a bit of DIY hive monitoring
You could leave this in the hive and just plug in for a look when you wanted
If you want to listen and the hive isn't too far away you could make one of these
only in rural areas though or the neighbours and the law might visit
