Metal matrix composites (MMCs) exhibit improved strength but suffer from low ductility. Metal particles reinforcement can be an alternative to retain the ductility in MMCs (Bauri and Yadav, 2010; Thakur and Gupta, 2007) [1,2]. However, processing such composites by conventional routes is difficult. The data presented here relates to friction stir processing (FSP) that was used to process metal ...

In this work, a decision tool is developed for a liner shipping company to deploy its fleet considering vessel speeds and to find routes for cargos with transit time constraints simultaneously. This problem is referred as Service level Assignment and Container Routing Problem (SACRP) in the sequel. A Column Generation (CG) algorithm is implemented for the SACRP. Computational experiments are pe...

The need for producing renewable fuels from biomass has increased due to depleting fossil resources and environmental concerns. However, the low fraction of carbon converted product is an undeniable drawback most current biofuel productions fermentation undecomposed lignin in composition loss as CO2. In this work, two main production routes MixAlco® process, ketonization route (KR) esterificati...

Ride-sharing services are transforming urban mobility by providing timely and convenient transportation to anybody, anywhere, and anytime. These services present enormous potential for positive societal impacts with respect to pollution, energy consumption, congestion, etc. Current mathematical models, however, do not fully address the potential of ride-sharing. Recently, a large-scale study hi...

13 Abstract Transport assignment models play an important role in the research and practice of transport planning. Traditionally, transport assignment models are link-based, predicting traffic volumes on network links. However, route-based transport assignment models, which work with route sets and determine traffic volumes of routes, became more important in recent years. They support advanced...

This paper considers the SLK/DIF due window assignment problems on a single machine with general job-dependent positional effect, where actual processing time of job is subject to and effect. Production schedulers may decide outsource/reject some jobs by paying corresponding costs. Based whether accept tardiness jobs, we consider two different objectives under slack assignment, respectively. Th...

We consider the problem of computing a set meaningful alternative origin-to-destination routes, in real-world road network instances whose arcs are accompanied by travel-time functions rather than fixed costs. In this time-dependent route scenario, we present novel query algorithm, called Time-Dependent Alternative Graph (TDAG), that exploits outcome time-consuming preprocessing phase to create...

Decoy routing is a recently proposed approach for censorship circumvention. It relies on cooperating ISPs in the middle of the Internet to deploy the so called “decoy routers” that proxy network traffic from users in the censorship region. A recent study, published in an award-winning CCS 2012 paper [24], suggested that censors in highly connected countries like China can easily defeat decoy ro...
