l outsourcing with a return policy is quite commonly adopted in the fashion supply chain. Under the return policy, the supplier as a brand owner may focus on production, and then outsource retailing to the retailer. In the meanwhile, the retailer may receive some support money from the supplier...

Inflation as measured by the personal consumption expenditures price index is near historical low levels, below the Federal Reserve’s 2% longer-run goal. Another common inflation measure, the consumer price index, is also historically low, but remains closer to 2%. The recent gap between these...

The well-known Phillips curve suggests that future inflation depends on current and past inflation and a measure of economic slack or resource utilization. Using the unemployment gap to measure slack, a simple Phillips curve currently predicts that inflation will remain quite low through 2015....

A series of essays authored by San Francisco Fed President and CEO John C. Williams, Senior Vice President and Associate Director of Research Mary C. Daly, Research Associate Yifan Cao, and Senior Economic Education Manager Jody Hoff, argue that the answer to the questions 'Does college matter?'...

We consider the problem of scheduling a given set of n jobs with equal processing times on m parallel machines so as to minimize the makespan. Each job has a given release date and is compatible to only a subset of the machines. The machines are ordered and indexed in such a way that a...

Spatial public goods game is a popular metaphor to model the dilemma of collective cooperation on graphs, yet the non-excludable property of public goods has seldom been considered in previous models. Based upon a coevolutionary model where agents play public goods games and adjust their...

Boron doped (B-doped) diamond films are deposited onto WC-Co inserts by HFCVD with the mixture of acetone, trimethyl borate (C3H9BO3) and H2. The as-deposited B-doped diamond films are characterized with scanning electron microscope (SEM), X-ray diffraction (XRD) spectroscopy, Raman...

In the present study, the finite volume method (FVM) is adopted to investigate the effect of gas outlet on the fluid field generated by a hot filament chemical vapor deposition (HFCVD) setup that is designed for the mass-production of diamond coated drills. The temperature field is calculated...

In the present study, the fluid field in a process of fabricating diamond coated cutting tools using the hot filament chemical vapor deposition (HFCVD) method is investigated using the finite volume method (FVM), in which the effects of the inlet height, gas initial velocity, inlet radius and...
