Providing sufficient Available Sight Distance (ASD) that meets the minimum design requirements is crucial for highway safety. Previous work on sight distance assessment focused Stopping (SSD) with little attention given to Passing (PSD). Insufficient PSD could lead severe collisions such as head-on and sideswipe crashes. To address this gap, paper introduces an automated method two-lane highway...

This paper proposes a new multi-objective based adaptive immune algorithm for solving the combined economic and environmental dispatch problem. Economic dispatch problem deals with the minimization of fuel cost while satisfying a set of equality and inequality constraints. The fossil fuel plants pollute the environment by emitting some toxic gases. Therefore, the traditional minimization of cos...

The paper investigates the performance of proposed search technique for different kinds of economic dispatch problems by searching generation pattern of committed units in polar coordinate system being projection of phasor on real axis with respect to its displacement. A slack generator is introduced to meet the demand constraint while generation pattern is searched within operating limits of g...

The observable long-time behavior of an isolated many-body system after a quantum quench is considered, i.e., eigenstate (or equilibrium ensemble) some pre-quench Hamiltonian $H$ serves as initial condition which then evolves in time according to post-quench $H_p$. Absence thermalization analytically demonstrated for large class quite common pre- and spin Hamiltonians. main requirement that the...

At the end of 2007, the fi nancial press celebrated that the São Paulo Stock Exchange (Bovespa) had successfully promoted the issue of new shares for 27 companies in that year alone. Abetted by low interest rates and improvements in corporate governance, corporations in Brazil had accomplished what seemed to be an all-time record number of initial public off erings (IPOs) in a single year. 1 Ye...
