 | The Collaborative Australian Ballistics Research code, Casbar, is a simulation tool for the analysis of the interior ballistics of guns. The code solves a two-phase, axisymmetric form of the governing equations for the flow of gas and particulates in the gun, and accommodates multiple projectiles within the simulation. Casbar is also suitable for investigating intermediate ballistics, and can alternatively be used as a general compressible flow solver. Casbar supports user-customised ... |

|
 | The correlation between the measured velocity component and the instantaneous particle rate in laser anemometry leads to a statistical bias of most commonly used estimators. An additional bias may occur in non-homogeneously seeded flows if a correlation exists between the velocity and the particle density. These statistical bias effects are investigated using numerical simulations. Models for the particle arrival statistics are derived using autoregressive (AR) time series of the first ... |

|
| The application of free piston shock tunnels to the simulation of real gas effects in hypersonic flight is discussed. It is pointed out that the primary simulation variables for this purpose are the stagnation enthalpy and the binary scaling parameter. The free piston reflected shock tunnel is considered first, and it is shown how test time limitations play a major role in determining the limiting stagnation enthalpy for a given ... |

|
| For a product sold with a warranty period T, the manufacturer must pay all repair costs for failures in (O,T). This paper presents a model to estimate warranty liability associated with this type of warranty policy. The quantities estimated are: (i) the expected total warranty cost and prediction interval for a fixed lot size of sales, and (ii) the expected number of units returned for repair and the expected warranty ... |
