Given an edge-distance graph of a set of suppliers and clients, the bottleneck problem is to assign each client to a selected supplier minimizing their maximum distance. We introduce minimum quantity commitments to balance workloads of suppliers, provide the best possible approximation algorithm, and study its generalizations and specializations. © 2005 Wiley Periodicals, Inc.

Optimization of turning process parameters in minimum quantity lubrication (MQL)-assisted mode is obligatory for enhanced efficiency and product integrity. However, little attention has been paid to analyzing situations where high search precision needed when evaluating the optimal parameters. This article applies grey wolf optimization (GWO) approach optimize AISI 4340 alloy enhance cutting fo...

Abstract This paper presents an effort to model the process parameters involved in turning of alloy steel AISI 4340 workpiece material with Al 2 O 3 and CuO hybrid nanofluids using minimum quantity lubrication (MQL) method. In this paper, effect mixing two nanoparticles (Al CuO) different weight percent environmentally friendly water-based cutting fluid, rotational speed, feed rate has been inv...

In the manufacturing industry, during machining, conventional cutting fluid plays a vital role; however, extravagant use of fluids due to its disposal affects environment badly. Nowadays, these advantages fluids, alternative methods or are preferred. One most preferred may be minimum quantity lubrication technique with nanoparticle-enriched fluids. The present paper has compilation investigatio...

Ensuring effective lubrication between sliding surfaces is one of the challenges in the field of tribology. In addition to the conventional parameters like speed, load, contact geometry and material parameters, the surface texture also influences the coefficient of friction. In the present investigation, the effect of surface texture on coefficient of friction under boundary lubricated conditio...
