This paper considers the problem of a continuous production process where both the mean and variance are simultaneously monitored by an (X) over bar chart and R chart respectively, and generalizes the model of Costa (IIE ...

The nonequivalent groups with anchor test (NEAT) design is widely used in test equating. Under this design, two groups of examinees are administered different test forms with each test form containing a subset of common ...

Research has shown that applying the T-2 control chart by using a variable parameters (VP) scheme yields rapid detection of out-of-control states. In this paper, the problem of economic statistical design of the VP T-2 ...

In 1907, aviation pioneer Santos-Dumont had the idea of building a very light airplane. He designed and built the SD19, the Demoiselle, an aircraft with a 6 meter wing span and a 24 HP engine of his own design. The ...
