Localization of robot and landmark with indistinguishability
… using specific measurement models, we develop a general algorithm for minimizing the position ranges under various conditions, which are related to the number of dimensions, the number of landmarks, and the value of the measurement model radius. We also study the characteristics of …

Localizing external contact using proprioceptive sensors : the contact particle filter
… the CPF, the Contact Particle Filter, which is a general algorithm for detecting and localizing external contacts on rigid body robots without the need for external sensing. The CPF finds external contact points that best explain the observed external joint torque, and returns sensible estimates …

A planned approach to high collision risk area
… Scheme (TSS). Previous autonomy approaches generally view path planning and collision avoidance as two separate functions, i.e. a vessel will follow the planned path until conditions are met for collision avoidance algorithms to take over. Here an intermediate phase is proposed with the goal …

Unstructured surface and volume decimation of tessellated domains
<p>A general algorithm for decimating unstructured discretized data sets is presented. The discretized space may be a planar triangulation, a general 3D surface triangulation, or a 3D tetrahedrization. The decimation algorithm enforces Dirichlet boundary conditions, uses only existing vertices, and …

Testing shape restriction properties of probability distributions in a unified way
… ... Building on a result of [9], we develop a general algorithm for this question, which applies to a large range of "shape-constrained" properties, including monotone, log-concave, t-modal and Poisson Binomial distributions. Our generic property tester works for properties that exclusively …

Example Based Processing For Image And Video Synthesis
… is that there are some problems where a single general algorithm can be used to create varieties of outputs, solely by presenting examples of what is desired to the algorithm. This is valuable if the algorithm to produce the output is non-obvious, e.g. an algorithm to emulate an example …

Problem-Specific Quantum Machine Learning and Quantum Algorithms: Data Embeddings, Symmetries and Structure
… quantum computing is the development of quantum algorithms which boast an advantage over classical protocols for solving problems. This thesis presents some original approaches to tackling this task. Specifically, I present several quantum machine learning and algorithmic procedures, some adapted …

Adaptive scaling of evolvable systems
… A particular feature of models such as Genetic Algorithms (GA) [18, 12] is the incremental combination of partial solutions distributed within a population of solutions. This mechanism in principle allows certain problems to be solved which would not be amenable to a simple local search. Such …

Modelling and multi-objective optimisation of heat transfer characteristics and pressure drop of nanofluids in microtubes
… was done with a multi-objective optimisation general algorithm. The outcome of the optimisation was that silicon dioxide, as nanoparticle, and water, as base fluid, would give the optimal setup. The diameter also appeared to have a very small effect on the outcome.
