    Abstract: A process for producing a preform by cold spray deposition, the process comprising: providing a starter substrate about a preform axis of rotation, the starter substrate having at least one axial end having a substantially flat deposition surface; rotating the starter substrate about the preform axis of rotation; depositing material onto the deposition surface of the starter substrate using cold spray deposition to form a product deposition surface, the cold spray deposition process including a cold spray applicator through which the material is sprayed onto the deposition surface; successively depositing material onto a respective top product deposition surface using cold spray deposition to form successive deposition layers of the material; and moving at least one of: the cold spray applicator; or the starter substrate and preform product, relative to the other in an axial direction along the preform axis of rotation to maintain a constant distance between the cold spray applicator and the top product deposition surface, thereby forming a preform product of a selected length, wherein the cold spray applicator is moved in a plane perpendicular to the preform axis of rotation so as to deposit material as a substantially flat surface on each respective deposition surface of the starter substrate or product deposition surface of the preform product.

    Abstract: A discrete element method for modelling granular or particulate material, the method including a multiple grid search method wherein the multiple grid search method is a hierarchical grid search method, and wherein entities, such as particles and boundary elements, are allocated to cells of respective grids based on size. The search method further includes: (a) performing a search of cells in a first of the grid levels to determine pairs of entities which satisfy predetermined criteria to be included in a neighbour list for which both entities belong to the first grid level; (b) mapping each nonempty cell in the first grid level to each of the other grid levels, determining neighbouring cells in each of the other grid levels and determining all pairs of entities belonging to pair of levels that satisfy the predetermined criteria for inclusion in the neighbour list; and (c) repeating (a) and (b) for all grid levels.

    Abstract: A method to determine a concentration of a target element in a sample is provide. The method comprises (i) positioning a sample containing a target element with respect to a reference material containing a reference element, (ii) simultaneously irradiating the sample and the reference material with Bremsstrahlung X-rays to thereby produce activated nuclei in the target element and to produce activated nuclei in the reference element, (iii) detecting deactivation gamma-rays' from the irradiated sample and deactivation gamma-rays from the irradiated reference material, (iv) determining a first number of detected deactivation gamma-rays from the irradiated sample and a second number of detected deactivation gamma-rays from the reference material, and (v) determining the concentration of the target element in the sample by first normalising the first number of detected deactivation gamma-rays from the irradiated sample by the second number of detected deactivation gamma-rays from the reference material. The variation of the reference element to target element cross section ratio over a range of electron beam energies is less than a predetermined measurement accuracy.
