New experiment is coming soon
Results of the first experiment will be discussed in a paper, which will be submitted to the
BOINC:FAST'2017 conference.
We also work on the next experiment, which will be launched soon.

New paper
A paper, in which it is described how we solve the inversion problems in underwater acoustics, was published. In this paper we consider the calculations performed on a computing cluster. Recently the similar calculations are performed in Acoustics@home.

Опубликована статья, в которой описано, как мы решаем обратные задачи подводной акустики. В этой статье рассматриваются вычисления, запущенные на кластере. В настоящий момент схожие вычисления мы запускаем в проекте Acoustics@home.

Credit compensation
All results, which were mistakenly marked as invalid, were marked as valid. The corresponding amount of credits were added to hosts, users and teams. I hope it will at least partially fix the problem.

Validation bug was fixed
Bug with validation of WUs results from different OSs (windows and Linux) was fixed. Sorry for this. Now validation is working in a proper way.

First experiment
The first experiment was launched. In this experiment, we will solve sound speed profile estimation in underwater acoustics. In particular, the data from Japan sea will be used. Here the sound speed of 1 water layer (close to the surface) is known, and we need to find the values of sound speed for other 4 water layers and also for the distance between the source and the reciever of a signal. Recently only application version for Linux was added. The version for Windows is coming soon.

Запущен первый эксперимент, в котором будет решена задача оценки профиля скорости звука в подводной акустике. Конкретнее, будут обработаны данные из Японского моря. По известной скорости звука в слое воды у поверхности будут восстанавливаются значения скоростей звука остальных четырех слоев воды, а также расстояние от источника сигнала до его приемника. В настоящий момент доступна только версия приложения для linxux. Версия для Windows появится в ближайшее время.
