Witryna1 wrz 2012 · The impulsive part of response can be calculated by replacing the boundary condition given in Eq. (16) with the boundary condition specified in Eq. (17). Having obtained the total and impulsive response values, the convective response is the difference between these two values. Witryna23 kwi 2015 · Being impulsive is when an individual acts on his instinct. The key difference between these two forms of behavior is that while being compulsive includes thinking about the act of performing, in impulsive behavior, the individual simply acts without thought. Both concepts are dealt with in abnormal psychology in the context of …
