We consider the offline scheduling problem to minimize the makespan on m parallel and identical machines with certain features. Each job and machine are labeled with the grade of service (GoS) levels, and each job can only be executed on the machine whose GoS level is no more than that of the...

Surface-modified Poly(ethylene terephthalate) (PET) fabrics were prepared through thionylchlorided cellulose nano-crystal (CNC) reacting with hydroxyl groups at the surface of the alkali-etched PET fabrics. X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy...

The oxygen enriched combustion of diesel engines can reduce smoke emission and increase engine thermal efficiency; however it can also lead to an increase of NO emission. In this paper, experiment was conducted on a turbocharged direct injection diesel engine, and oxygen-enriched and EGR...

There is a lack of the capacity to respond to peak loads in most provincial power grids of eastern China and coastal regions. A CDA (central dispatching authority), which is usually a regional power grid, is responsible to dispatch its own plants and allocate power generation to multiple...
