What Creates Static Electricity?

Static electricity and rotameters.

Inaccuracies in Rotameters, caused by static charges, seem to be relatively common. Inaccuracies can be of a very serious order. Charges outside the tubes can be removed easily by antistatic spray. Charges inside the tube are very difficult to remove except by dismantling the apparatus or by the use of a radioactive pistol. Charges have been measured and are much larger than had been supposed a...

Computing Static Electricity on Human Hair

We present a framework to study electrical charge phenomena on human hair. We propose a fiber based hair model which bases on the special theory of Cosserat Rods to overcome the well known difficulties one has to deal with when simple particle systems are used. We show how such models can efficiently be employed in conjunction with the fast multipole method to account for Coulomb far-field inte...

Electricity Load Pattern Hedging with Static Forward Strategies

We consider the partial hedging of stochastic electricity load pattern with static forward strategies. We assume that the company under consideration maximizes the risk adjusted expected value of its electricity cash flows. First, we calculate an optimal hedge ratio and after that we use this hedge ratio to solve the optimal hedging time. Our results indicate, for instance that agents with high...

From what might have been to what must have been: counterfactual thinking creates meaning.

Four experiments explored whether 2 uniquely human characteristics-counterfactual thinking (imagining alternatives to the past) and the fundamental drive to create meaning in life-are causally related. Rather than implying a random quality to life, the authors hypothesized and found that counterfactual thinking heightens the meaningfulness of key life experiences. Reflecting on alternative path...
