Facets of a mixed-integer bilinear covering set with bounds on variables
, 2019 We derive a closed form description of the convex hull of mixed-integer bilinear covering set with bounds on the integer variables. This convex hull description is determined by considering some orthogonal disjunctive sets defined in a certain way.

MM Algorithms for Geometric and Signomial Programming
, 2010 This paper derives new algorithms for signomial programming, a generalization of geometric programming. The algorithms are based on a generic principle for optimization called the MM algorithm. In this setting, one can apply the geometric-arithmetic mean

Asynchronous Convex Consensus in the Presence of Crash Faults [PDF]
, 2015 This paper defines a new consensus problem, convex consensus. Similar to vector consensus [13, 20, 19], the input at each process is a d-dimensional vector of reals (or, equivalently, a point in the d-dimensional Euclidean space).

Geometry of Power Flows and Optimization in Distribution Networks
, 2013 We investigate the geometry of injection regions and its relationship to optimization of power flows in tree networks. The injection region is the set of all vectors of bus power injections that satisfy the network and operation constraints.

Effect of Hull Form Variations on Slamming and Dynamic Response in a Naval Vessel
Journal of Naval Architecture and Marine TechnologyThis study evaluates the influence of specific hull-form parameters on slamming behavior. The hull of a military frigate was adopted as the baseline geometry, and systematic variations were generated by modifying one form parameter at a time.
