Optimization-based motion planning for legged robots

Legged machines have the potential to traverse terrain that wheeled robots cannot. These capabilities are useful in scenarios such as stairs in homes or debris-filled disaster scenes, such as earthquake areas. This thesis develops one of the algorithms nec ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang, Jie Bian

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...

MATHICSE Technical Report : Perturbation of higher-order singular values

Daniel Kressner, André Uschmajew

The higher-order singular values for a tensor of order d are defined as the singular values of the d different matricizations associated with the multilinear rank. When d≥3, the singular values are generally different for different matricizations but not c ...

Path-following gradient-based decomposition algorithms for separable convex optimization

Quoc Tran Dinh

A new decomposition optimization algorithm, called path-following gradient-based decomposition, is proposed to solve separable convex optimization problems. Unlike path-following Newton methods considered in the literature, this algorithm does not require ...

Sliding Mode Control in Ziegler’s Pendulum With Tracking Force: Novel Modeling Considerations

Mehran Khaghani, Ehsan Sarshari

Ziegler's pendulum is an appropriate model of a nonconservative dynamic system. By considering gravity effect, new equations of motion are extracted from Newton's motion laws. The instability of equilibriums is determined by linear stability analysis. Chao ...

Study of IR Design for the LHC Upgrade

Stephan Russenschuck, José Luis Abelleira Fernández, César Octavio Domínguez Sánchez De La Blanca, Frank Zimmermann

A conceptual novel optics was developed for a future upgrade of the LHC interaction regions (IR). Applying the collision scheme with a large Piwinski angle and crab waist, originating from e+e- colliders, to an existing pp collider requires fairly unequal ...

Bound states of the Schrodinger-Newton model in low dimensions

Joachim Stubbe, Marc Vuffray

We prove the existence of quasi-stationary symmetric solutions with exactly n >= 0 zeros and uniqueness for n = 0 for the Schrodinger-Newton model in one dimension and in two dimensions along with an angular momentum m >= 0. Our result is based on an analy ...

A dynamic preconditioner for Newton-Krylov algorithms. Application to fluid-structure interaction

Simone Deparis

We consider linear and nonlinear convergence acceleration techniques in the framework of Newton or inexact Newton methods. The proposed procedure is based on a new dynamic preconditioner to be used in combination with the GMRES method for reducing the cost ...

An algorithm for unsteady viscous flows at all speeds

Michel Deville

An algorithm for the simulation of unsteady, viscous, stratified compressible flows, which remains valid at all speeds, is presented. The method is second-order accurate in both space and time and is independent of the Mach number. In order to remove the s ...
