We consider the problem of cardinality penalized optimization of a convex function over the probability simplex with additional convex constraints. The classical `1 regularizer fails to promote sparsity on the probability simplex since `1 norm on the probability simplex is trivially constant. We propose a direct relaxation of the minimum cardinality problem and show that it can be efficiently s...

Oxygen is crucial to maintain and save human life. Other than medical purposes it is widely used for manufacture of mineral water, fabrication works and other industrial activities. If adequate precautionary measures are not adopted while handling, storage or transport of oxygen cylinder or container, accidental blast may claim human life and other damage as well. The case involving three victi...

This paper presents a new powerful side-channel cryptanalytic method algebraic collision attacks representing an efficient class of power analysis being based on both the power consumption information leakage and specific structure of the attacked cryptographic algorithm. This can result in an extremely low measurement count needed for a key recovery. The algebraic collision attacks are well ap...

The seismic resilience of a system can be achieved by reducing its probability of failure during an earthquake, as well as reducing the consequences from such failures and the time to recovery. Within the perspective of this framework, this paper explores the physical resilience of facilities. Quantification of resilience is first approached from the broader societal context, from which the eng...
