Vibration_theory_of_olfaction

Vibration theory of olfaction. The Vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. The theory is opposed to the more widely accepted shape theory of olfaction, which proposes that a molecule's smell character is due to its shape.

Vibration theory of olfaction

The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak noncovalent interactions .

Dynamic Analysis Of Vibration Screen

Vibration screen is often used for stered materials in most areas of mining, metallurgy, building materials, food, medicine, ... Matrix theory plays a pivotal role in modal analysis. This is because modal analysis theory is largely based on the analysis of a multidegreeoffreedom (MDoF) dynamic system which relies ...

Differential Equations

 · In this section we will examine mechanical vibrations. In particular we will model an object connected to a spring and moving up and down. We also allow for the introduction of a damper to the system and for general external forces to act on the object.

Theory of Frequency Captured of Eccentric Rotor by Vibration ...

Aiming at the frequency synchronization phenomena of oscillating or rotating bodies, this paper proposes a novel solution to address the selfsynchronization problem of vibration systems. An integral mean method with small parameters and periodic coefficient (IMMSPPC) is proposed, which converts the relative motion of the electrically driven eccentric rotor and the vibration .

It's All About Vibrations: A Resonance Theory of Consciousness

 · One of the main aspects of resonance theory is the idea that what we as humans experience as consciousness is based on the vibrational frequency of all matter. It's what hold the universe together, or what tears it apart. But this is only the starting point. What happens when these various vibrational phenomenon start to 'sync up'?
