Behavior Definition and 337 Threads

Behavior (American English) or behaviour (British English; see spelling differences) is the actions and mannerisms made by individuals, organisms, systems or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector.

    Prove the lorentzian function describes resonant behavior

    Homework Statement Resonances occur in many physical systems, and are often observed by measuring the frequency response of the system to an applied driving force. use the example of a damped harmonic oscillator to show how the lorentzian function serves as a good description of resonant...

    Unusual Golf Ball Behavior: Investigating an Unexplained Force vs Distance Graph

    I am almost done in my research on golf balls, however I found something unusual which I can't seem to find an explanation for. After collecting data on a golf swing (golf ball speed, club head speed, backspin, distance etc.) I created a few graphs. Once of them was a force vs distance graph...

    Turning car Centripetal Acceleration behavior?

    Hi all! A professional race-car driver is asked to make 2 different "quarter-circle" turns on a racing track. He completes them at the highest possible constant linear speed (he is well familiar with the car and the road so it's an easy task for him). Turn 1: Radius is R1=20m. Linear...

    Basic limits of rational functions: behavior near vertical asymptotes

    Homework Statement We are required to sketch a (reasonably accurate) picture of a rational function f(x) = P(x)/Q(x) with P, Q polynomials in x and Q nonzero. We know that the roots of Q(x) are, say, x1, x2, etc. and so f(x) is (typically) asymptotic to the vertical lines x = xk for each k...

    How do electrons behave in resistive circuits and semiconductors?

    For a simple network of resistive circuit, we can compute the values of current and voltages right? However, I'm more curious about how each individual component behave. Is it possible to somehow isolate each resistor and compute their values individually (e.g. not having to compute the entire...

    Behavior of Photons During Reflection.

    Which of the following is consistent with experiment/observation. When light is reflected off of a material, what happens to the photon? A. Is it absorbed by the electron or lattice and then re-emitted? OR B. Does it somehow just reflect/bounce off the electron/lattice? Kind of...

    Perhaps we do see quantum behavior at the macroscopic scale

    Okay, I will preface this by saying that I have no formal education in physics. I am just a regular man with an active mind and healthy dose of curiosity. There may be some errors in my terminology, but hopefully you'll get what I am saying. Heck, maybe this is already a well known hypothesis...
