Adaptive Path Planning for Depth Constrained Bathymetric Mapping with an Autonomous Surface Vessel

, 2016
This paper describes the design, implementation and testing of a suite of algorithms to enable depth constrained autonomous bathymetric (underwater topography) mapping by an Autonomous Surface Vessel (ASV).

Flip Distance Between Triangulations of a Simple Polygon is NP-Complete

, 2017
Let T be a triangulation of a simple polygon. A flip in T is the operation of removing one diagonal of T and adding a different one such that the resulting graph is again a triangulation.

Laminations and groups of homeomorphisms of the circle

, 2002
If M is an atoroidal 3-manifold with a taut foliation, Thurston showed that pi_1(M) acts on a circle. Here, we show that some other classes of essential laminations also give rise to actions on circles.

A strongly monotonic polygonal Euler scheme

Journal of Complexity
In recent years tamed schemes have become an important technique for simulating SDEs and SPDEs whose continuous coefficients display superlinear growth. The taming method, which involves curbing the growth of the coefficients as a function of stepsize, has so far however not been adapted to preserve the monotonicity of the coefficients. This has arisen

Rapid Discovery of Sequence‐Encoded Magnetically Reconfigurable Microrobots Using Monte Carlo Simulations

Advanced Intelligent Systems, EarlyView.
A Monte Carlo simulation framework is introduced to predict the folding behavior of sequence‐encoded magnetic microrobots, enabling systematic exploration of their design space. By mapping key metrics such as radius of gyration and symmetry, the framework identifies functional sequences and predicts actuation behaviors.

Pre‐Excavation Identification and Dating of Iron Age Destruction Events

Archaeological Prospection, EarlyView.
ABSTRACT To maximize extracted data while minimizing excavated areas, archaeologists increasingly use archaeological surveys, geophysical surveys and remote sensing to gain comprehensive regional pictures and decide if and where to excavate. The goal of this effort is to leave sufficient unexcavated areas for future generations and save time and ...

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

Archaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Circular-Arc Cartograms

, 2012
We present a new circular-arc cartogram model in which countries are drawn as polygons with circular arcs instead of straight-line segments. Given a political map and values associated with each country in the map, a cartogram is a distorted map in which
