Switching Current Distributions of Superconducting Nanowires: Evidence of Quantum Phase Slip Events
… events, which are known as quantum phase slips (QPS). However, experimental observation of QPS is a subject of strong debate and no consensus has been reached so far about the conditions under which QPS occurs. In this study, strong evidence for individual quantum tunneling events undergone by …

Distributed Feedback Control Algorithms for Cooperative Locomotion: From Bipedal to Quadrupedal Robots
… this thesis exploits the idea of distributed QPs. In particular, this thesis presents a formal foundation to systematically decompose QP-based centralized nonlinear controllers into a network of lower-dimensional local QPs. The proposed approach formulates a feedback structure be- tween the …

Quantum chaos and phase transitions
… probing for the presence of quantum phases (QPs) of matter and the transitions (QPTs) among them. Specifically, it proposes that Krylov Complexity can be utilized to detect QPs and QPTs. Krylov Complexity is a quantity that has been recently proposed in the physics literature as a measure of …

Decompositionality and identity
The Scope of quantificational phrases (QPs) is often not represented in surface structures, in the sense that a constituent that is, on the surface, sister to a QP is not necessarily interpreted as its argument semantically. QPs can take wider or narrower scope than their surface position (Scope …

Microwave Response in Superconducting Nanowires
… the occurrence of a single quantum phase slip (QPS) which in the presence of a high bias current creates enough heat to warm the wire to a temperature above TC, or, in the presence of MW, triggers the PSC dynamic state. We present a model for the increase of the rate of QPS with the increase in …

Prosthetic socket design : from a multi-indenter device for in vivo biomechanical tissue measurement to a quasi-passive transtibial socket interface
… the laboratory setting. A quasi-passive socket (QPS) is presented having spatially and temporally varying socket wall impedances. The QPS is an autonomous computerized transtibial prosthetic interface that can stiffen or become compliant using computer-controlled electrolaminate actuators. The …

Probing quantum phase slips in superconducting nanowires modified using high bias voltage pulses
Quantum phase slips (QPS) or the macroscopic quantum tunneling (MQT) of a nanowire’s order parameter through an activation energy barrier have remained the subject of intense debate for many years. They are expected to occur at low enough temperature where thermally activated phase slips (TAPS) …

A model predictive control approach to a class of multiplayer minmax differential games
… one to solve a sequence of Quadratic Programs (QPs), which together efficiently solve the original semi-infinite min- max MPC problem. The solution method separates the problem into two subproblems called the inner and outer subproblems, respectively. The inner subproblem is based on a …

Dissipative processes in superconducting nanodevices: nanowire-resonators, shunted nanowires, and graphene proximity junctions
… quantum behavior such as quantum phase slips (QPS), and the potential use of nanowires as qubits. Superconducting coplanar microwave waveguide resonators have also become a popular way of studying superconducting junctions and qubits, as they provide an extremely low noise environment. For …

Collaborative Locomotion of Quadrupedal Robots: From Centralized Predictive Control to Distributed Control
… agents. The distributed MPC assumes two local QPs that share their optimal solutions according to a one-step communication delay and an agreement protocol. At the lower level of the control scheme, distributed nonlinear controllers are employed to impose the full-order dynamics to track the …

Robust Predictive Control for Legged Locomotion
… predictive control (RMPC) scheme based on convex QPs to bridge this gap. The RMPC framework considers the single rigid body model subject to a set of unmodeled dynamics and plans for the optimal reduced-order trajectory and GRFs. The generated optimal GRFs of the high-level RMPC are then mapped to …
