We investigate (1,λ) ESs using isotropic mutations for optimization in R by means of a theoretical runtime analysis. In particular, a constant offspring-population size λ will be of interest. We start off by considering an adaptation-less (1,2) ES minimizing a linear function. Subsequently, a piecewise linear function with a jump/cliff is considered, where a (1+λ) ES gets trapped, i. e., (at le...

Exploration of high risk terrain areas such as cliff faces and site construction operations by autonomous robotic systems on Mars requires a control architecture that is able to autonomously adapt to uncertainties in knowledge of the environment. We report on the development of a software/hardware framework for cooperating multiple robots performing such tightly coordinated tasks. This work bui...

We present a low complexity encoder and mapper for wireless multiple-input multiple-output (MIMO) systems. The BLAST (Bell Laboratories Layered Space-Time) algorithm is enhanced by a dedicated iterative QAM demapper with antiGray code. At the the transmitter a low complexity convolutional encoder and a QAM mapper with anti-Gray code are used, whose EXIT (Extrinsic Information Transfer) chart ar...

Examples are a powerful tool for teaching both humans and computers. In order to learn from examples, however, a student must first extract the examples from its stream of perception. Snapshot learning is a general approach to this problem, in which relevant samples of perception are used as examples. Learning from these examples can in turn improve the judgement of the snapshot mechanism, impr...

Capo Faro Promontory, located in Salina (Aeolian Islands, southern Italy), is a popular summer destination due to its volcanic morphologies, seaside, and enogastronomy. A flat area, right behind the scarp edge of coastal cliff, hosts Estate, one most renowned vineyards residences on Island. The promontory has been characterised terms geomorphological features. Remote sensing analysis, after nad...

Abstract. Modeling suggests that steep coastal regions will experience increasingly rapid erosion related to climate-change-induced sea level rise. Earthquakes can also cause intense episodes of cliff retreat, but coseismic failures are rarely captured in the historical record used calibrate most retreat forecast models. Here, we disaggregate cliff-top strong ground motion and non-seismic sourc...

One of the most often told anecdotes in psychology concerns a man called S. B. (initials used to protect his privacy). S. B. had been blind his entire life until the age of 52, when a newly developed operation (the now-common corneal transplant) was performed on him and his sight was restored. However, S. B.'s new ability to see did not mean that he automatically perceived what he saw the way t...

The survival probability of a particle diffusing in the two dimensional domain x > 0 near a " windy cliff " at x = 0 is investigated. The particle dies upon reaching the edge of the cliff. In addition to diffusion , the particle is influenced by a steady " wind shear " with velocity v(x, y) = v sign(y) ˆ x, i. e., no average bias either toward or away from the cliff. For this semi-infinite syst...

Halios, Department of Meteorology, University of Reading, Early Gate, PO Box 243, Reading RG6 6BB, UK e-mail: [email protected] Geometric shapes of coherent structures such as ramp or cliff like signals, step changes and waves, are commonly observed in meteorological temporal series and dominate the turbulent energy and mass exchange between the atmospheric sur...

This paper presents a new form of consensus that allows nodes to agree locally on the extent of crashed regions in networks of arbitrary size. One key property of our algorithm is that it shows local complexity, i.e. its cost is independent of the size of the complete system, and only depends on the shape and extent of the crashed region to be agreed upon. In this paper, we motivate the need fo...
