ce/papers, 2022 AbstractThe prediction of the buckling resistance of shells is subject to uncertainty since it depends significantly on the initial geometric imperfections caused by the fabrication process. However, the load case of vacuum or uniform external pressure has not yet been extensively studied.

A comparison between lift-and-project indices and imperfection ratio on web graphs
Electronic Notes in Discrete Mathematics, 2010 Abstract In this paper we study the lift-and-project polyhedral operators defined by Lovasz and Schrijver [L. Lovasz, A. Schrijver, Cones of matrices and set-functions and 0-1 optimization, SIAM J. Optimization 1, (1991), pp. 166–190] and by Balas, Ceria and Cornuejols [3] on the clique relaxation of the stable set polytope of webs.

Constructal law of vascular trees for facilitation of flow. [PDF]
PLoS ONE, 2014 Diverse tree structures such as blood vessels, branches of a tree and river basins exist in nature. The constructal law states that the evolution of flow structures in nature has a tendency to facilitate flow.

A note on imperfect hedging: a method for testing stability of the hedge ratio
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 Companies producing, processing and consuming commodities in the production process often hedge their commodity expositions using derivative strategies based on different, highly correlated underlying commodities. Once the open position in a commodity is hedged using a derivative position with another underlying commodity, the appropriate hedge ratio ...

Imperfect reference standards cause biased likelihood ratios
Scandinavian Journal of Clinical and Laboratory InvestigationIn a study of the diagnostic accuracy of a quantitative biomarker, the researcher compares the concentration of the biomarker in patients with and without the disease in question. The diagnosis must be set without knowledge of the biomarker concentration, using the best reference standard available.
