In this paper, a discrete variant of TLBO (DTLBO) is proposed for solving the traveling salesman problem (TSP).In the proposed method, an effective learner representation scheme is redefined based on the characteristics of TSP problem.Moreover, all learners are randomly divided into several sub-swarms with equal Ball - Bat - Slo Pitch amounts of le
Considering the characteristics of carbonate reservoirs in the Middle East, a low-viscosity microemulsion acid that can be prepared on site and has an appropriate retardation ability was developed.It was compared with four Ice and Water Dispensers conventional acid systems (hydrochloric acid, gelled acid, emulsified acid and surfactant acid) throug
With the rise of corruption as a subject of international instruments and the convergence of obligations around its prevention, detection, and remediation in both the public and private sectors, corruption has increasingly figured as an issue in international arbitration.Indeed, its acceptance as a public policy issue at both the international and
A new annular lift fan configuration that has very high lift efficiency is explored by using a numerical scheme.The inlet lip radius and diffuser angle are maximized by semicircle duct walls and the location of the lift fan is moved from the throat to the diffuser area to maximize the diffusion effect of the ducted fan.The meaure improved lift fan
