Intrinsic structural transitions of the pyramidal I < c plus a > dislocation in magnesium

The stability of a mixed < c + a > dislocation on the pyramidal I plane in magnesium is studied using molecular dynamics simulations. The dislocation is metastable and undergoes a thermally-activated transition to either a sessile, basal-dissociated < c + ...

Highly efficient and gentle trapping of single cells in large microfluidic arrays for time-lapse experiments

Jürgen Brugger, Marco Grisi, Filiz Yesilköy

The isolation of single biological cells and their further cultivation in dedicated arrayed chambers are key to the collection of statistically reliable temporal data in cell-based biological experiments. In this work, we present a hydrodynamic single cell ...

Viability evolutionary algorithms and applications to neuroscience and biology

Andrea Maesani

Evolutionary algorithms are heuristic methods that operate on a population of individuals, which represent candidate solutions to optimization problems. Individuals with better quality, or fitness, are reproduced at a higher rate than less fit individuals ...

Deployment of a tensegrity footbridge

Ian Smith, Nicolas Willy Veuve, Seif Dalil Safaei

Deployable structures are structures that transform their shape from a compact state to an extended in-service position. Structures composed of tension elements that surround compression elements in equilibrium are called tensegrity structures. Tensegritie ...

Viability Principles for Constrained Optimization Using a (1+1)-CMA-ES

Dario Floreano, Andrea Maesani

Viability Evolution is an abstraction of artificial evolution which operates by eliminating candidate solutions that do not satisfy viability criteria. Viability criteria are defined as boundaries on the values of objectives and constraints of the problem ...

Artificial Evolution by Viability Rather Than Competition

Dario Floreano, Andrea Maesani, Pradeep Ruben Fernando

Evolutionary algorithms are widespread heuristic methods inspired by natural evolution to solve difficult problems for which analytical approaches are not suitable. In many domains experimenters are not only interested in discovering optimal solutions, but ...

Towards the Layered City: Redefining the Role of Underground Resources in Future Urbanization

Michael Robert Doyle

For the past century, the urban underground has been developed piecemeal rather than as the object of a long-term planning effort. There is a growing awareness by urban planners and engineers that the underground contains not only potential usable space, b ...

Mechanism-Based Approach for the Deployment of a Tensegrity-Ring Module

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, Costanza Schulin, René Motro

Tensegrity structures are spatial systems composed of tension and compression components in a self-equilibrated prestress stable state. Although the concept is over 60 years old, few tensegrity-based structures have been used for engineering purposes. Tens ...

From Composites to Service Systems: The Role of Emergence in Service Design

Alain Wegmann, Anshuman Bahadur Saxena

Service Design is an engineering endeavor to enrich some aspect of the real world through a man-made artifact. Systems approach to modeling reality is particularly relevant to Service Design as it seeks to explain reality as a composition of functional obs ...
