Hardest 10. Diamond he selection of abrasive media for blast cleaning steel is based primarily on two broad objectives, quality and economics. Quality is defined in terms of appearance after cleaning (SSPC-SP 7, 6, 10, and 5 ) , profile depth and contour, and chemical cleanliness. The economics of an abrasive is determined by its initial cost and by the production rate that can be achieved when...
We develop a procedure called RiPE (Retrieval-induced Phylogeny Environment) that automatically performs an evolutionary analysis of a protein (sub)family, (i) by retrieving the relevant sequences via a homology search, (ii) by using the search report to construct the alignment using only homologous subsequences (taking into account their neighborhood with a low chance of homology), (iii) by re...
Safety-critical systems rely on various forms of machine arithmetic to perform their tasks: integer arithmetic, fixed-point arithmetic or floating-point arithmetic. Machine arithmetic can exhibit subtle differences in behavior compared to the ideal mathematical arithmetic, due to fixed-size of representation in memory. Failure of safety-critical systems is unacceptable, because it can cost live...
Shot Peening process relies on multiple impacts of spherical media to a surface to achieve residual compressive stresses.

The objectives of this study were to characterize change in surface properties of tetragonal zirconia polycrystals (TZP) after hydrophilic treatment, and to determine the effect of such changes on initial attachment of osteoblast-like cells. Roughened surfaces were produced by alumina-blasting and acid-etching. Hydrophilic treatment comprised application of immediately after blasting and acid-e...
Preliminary notes This paper aims to establish the parameters of optimization and geometrical improvements for the micro-geometry of solid carbide drills through the application of sand blasting process. The effects of sand blasting over the cutting edge and also upon the micro geometry of the tool body are to be taken into consideration. This process is one of the most common ones used in the ...
This paper presents work in progress on an approach to the problem of recognizing blasting caps in x-ray images. An analysis of functional properties of blasting caps was used to design the representation space, which combines intensity and shape features. Recognition proceeds in two phases. The rst phase is a bottom-up process in which low intensity blobs are used as attention-catching devices...
The branch-and-bound framework has already been successfully applied in SAT-modulo-theories (SMT) solvers to check the satisfiability of linear integer arithmetic formulas. In this paper we study how it can be used in SMT solvers for non-linear integer arithmetic on top of two real-algebraic decision procedures: the virtual substitution and the cylindrical algebraic decomposition methods. We im...
Front row burden is one of the key parameter to improve the bench blasting results. Improper design of the front row burden can create nuisances in the form of ground vibration, flyrock, back break or it may responsible for breakage of improper fragment size from the rockmass. Therefore, front row burden need to be optimised on the basis of proper scientific assessment. It has been proved that ...
We present a new method for solving nonlinear integer arithmetic constraints. The method relies on the MCSat approach to solving nonlinear constraints, while using branch and bound in a conflict-directed manner. We report encouraging experimental results where the new procedure outperforms state-of-the-art SMT solvers based on bit-blasting.
