Body segmental inertial properties are required for inverse dynamics modeling. Using an oscillation and reaction board technique, inertial properties of below-knee prostheses were measured. Using direct measures of prosthesis inertia in the inverse dynamics model of the prosthetic leg resulted in lower magnitudes of resultant joint forces and moments.

This video demonstrates the recording of rhythmic neuronal network activity, also known as theta oscillations, in an isolated hippocampus. Electrodes are inserted into various layers and spatial positions to detect and analyze theta oscillations. This shows the unique neuronal compositions and the connectivity of the neuronal network across different layers of the hippocampus.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Forced Oscillations

When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined. Using the equations of force and motion, the amplitude of the driven oscillator is obtained. It depends on the natural and driving frequency. In the equation for amplitude, when the driving frequency is much smaller...

In the relation f = (1/2π)√(k/m), mass appears in the denominator under the square root. Because of this placement, increasing the attached mass reduces the oscillation frequency rather than producing a proportional change. The effect provides a quantitative way to connect a measured vibration rate with the mechanical properties of the oscillating system.
The spring constant represents the restoring-force behavior of the spring in the oscillating system. With mass held constant, a larger spring constant produces a higher frequency, while a smaller one produces a lower frequency. Considering both quantities together is essential because the observed motion reflects their ratio, not mass alone.
Frequency and period describe the same repeating motion from different perspectives: frequency indicates cycles per unit time, whereas period indicates the time for one cycle. Since increasing mass lowers the frequency in a mass-spring system, the corresponding period becomes longer. This inverse interpretation helps explain measured timing changes when the attached mass is varied.
If the spring constant is known, researchers can measure the oscillation frequency and rearrange f = (1/2π)√(k/m) to obtain the unknown mass. The measured frequency is inserted into the relationship together with the known spring constant. A lower measured frequency indicates a larger inferred mass within the modeled oscillating system.
When the mass is known, measuring the oscillation frequency allows the spring constant to be inferred from the same equation. Rearranging gives k = m(2πf)², so the measured frequency and known mass provide the required quantities. This approach links dynamic vibration measurements to a mechanical property that may not be directly available.
The relationship supports analysis of pendulums, mechanical sensors, structural systems, and other devices that rely on controlled vibrations. In these settings, mass and restoring behavior determine the characteristic oscillation rate. Understanding that dependence helps researchers analyze existing motion, select suitable system parameters, and interpret vibration measurements in mechanics and vibration analysis.
