16. Weak signals.

Bulgaria Make an investigation, based on data with a low signal-to-noise ratio to explore a distant Space object.

Croatia Controlling signal-to-noise ratio is important in computational neuroscience to distinguish a signal that caused an action potential from a statistical fluke. Propose a simulation of a given problem and investigate how filtering techniques help identify unknown parameters, e.g. ion channel conductance values, in electrophysiological recordings.

Georgia Create a device that will distinguish seismic waves from random noise.

Greece-Alliance Detection of weak signals in the case of electromagnetic leakage, to examine the risks to home computers.

Greece-Fryganiotis Find a way to detect weak signals in noise by utilizing data in regard to the electromagnetic field of the audio source.

Iran-Innovative Researchers In alternating signals, the necessary and effective factors in obtaining the signal-to-noise ratio are the calculation of the signal proportionality period.

Iran-Valeh What is Signal-to-noise ratio? Where is it used? How it is measured? What is statistical fluke? How we can detect very weak signals? In alternating signals, the necessary and effective factors in obtaining the signal-to-noise ratio are the calculation of the signal proportionality period. In the signal-to-noise ratio, it is important to consider the modulation signals to the average noise power. When the signals interfere with the noise, we reduce the noise by obtaining the harmonics created. One of the factors affecting meaningful signals is the presence of magnetic fields that can be reduced or eliminated to prevent the reduction of meaningful signals.

Kazakhstan-Bobek We ask to study different examples of weak signals.

Kazakhstan-RFMS Examine the effect of materials on the WIFI signal. Under what conditions will the signal be weak and how to pick it up?

New Zealand Gravitational waves were predicted by Einstein many years ago but have only been detected in the last few years using sophisticated observatories. Compare light interferometer data to predicted models of stellar collisions to determine if gravitational waves signals can be separated from background noise. Explain the techniques used to minimise noise and improve the strength of the signal.

Romania-LIMITLESS Interpret meaningful weak signals from statistical flukes in different fields (stock market, audio recordings, etc.)

Romania-NITRO Test peoples accuracy in detecting common examples of weak signals.

Russia-Unartificial Intelligence How to use software for analyzing and correction of sound frequency signal?
