Finite Element Analysis of Multi-Stable Structures

Electrochemically-actuated Morphing Helicopter Blade

The use of the expansion of lithium-ion cells for mechanical actuation has been recently reported by Chin et. al. (1). Under a stress of 10 MPa, actuating strains of up to 1.5% were achieved. Taking into account the cells approximate elastic modulus, this strain corresponds to a mechanical energy density ten times higher than that of current piezoelectric materials, although with slower actuati...

Morphing Between Stable Matching Problems

In the stable roommates (SR) problem we have n agents, where each agent ranks all other agents in strict order of preference. The problem is then to match agents into pairs such that no two agents prefer each other to their matched partners, and this is a stable matching. The stable marriage (SM) problem is a special case of SR, where we have two equal sized sets of agents, men and women, where...

Fuzzy retrieval of encrypted data by multi-purpose data-structures

The growing amount of information that has arisen from emerging technologies has caused organizations to face challenges in maintaining and managing their information. Expanding hardware, human resources, outsourcing data management, and maintenance an external organization in the form of cloud storage services, are two common approaches to overcome these challenges; The first approach costs of...
