The goal of developing a firmer theoretical understanding of inhomogeneous temporal processes–in particular, the waiting times in some collective dynamical system–is attracting significant interest among physicists. Quantifying the deviations between the waiting-time distribution and the...

The long term performance and durability evaluation of a compression ignition (CI) engine of a diesel power generator using ultra-low sulfur diesel (ULSD) and Synthetic Paraffinic Kerosene, (S-8) fuels have been investigated under military specifications. The brake specific fuel consumptions...

Two central puzzles about social norms are how they are enforced and how they are created or modified. The sanctions for violation of a norm can be categorized as automatic, guilt, shame, informational, bilateral- costly, and multilateral-costly. Problems in creating and enforcing norms are...
