To demonstrate biofilm formations on a cochlear implant magnet of a pediatric patient suffering from a methicillin-resistant Staphylococcus aureus (MRSA) infection. The appearance of biofilm colonies was analyzed on different magnet sections. The appearance of MRSA biofilms on the surface of an explanted cochlear implant was analyzed by scanning electron microscopy (SEM), focusing on the patter...

Most of existing crowd simulation algorithms focus on the moving trajectories of individual agents, while collective group formations are often roughly learned from video examples or manually specified via various hard constraints (e.g., pre-defined keyframes of exact agent distributions). In this paper, we present an intuitive yet efficient approach to generate arbitrary and precise group form...

1.1 Carbon dioxide sequestration in sub-seabed geological formations is a process consisting of separation of carbon dioxide from industrial and energy-related sources, transport to an offshore geological formation, and long-term isolation from the atmosphere. This process is one option in a portfolio of mitigation actions for stabilization of atmospheric greenhouse gas concentrations with the ...

It is hypothesized that the striate cortex is concerned with, among other things, removing binocular correlations in the inputs. This theory is applied to explain the diierent ocular dominance column (ODC) formations observed after visual developments under strabismus, excessive binocular correlations, normal environment, and monocular deprivation. These ODC formations are shown to be consequen...

We provide a cooperative control algorithm to stabilize symmetric formations to motion around closed curves suitable for mobile sensor networks. This work extends previous results for stabilization of symmetric circular formations. We study a planar particle model with decentralized steering control subject to limited communication. Because of their unique spectral properties, the Laplacian mat...

One potentially cost-effective approach to harvesting solar power from space is the use of thousands of individual robots moving in formation, each with a piece of solar panel attached, to form a solar panel array. In previous work, we demonstrated an algorithm that treats a group of robots as a 1-dimensional cellular automaton, which is able to establish formations defined by a single mathemat...

In prior work we established how artificial physics can be used to self-organize swarms of mobile robots into hexagonal formations that move toward a goal. In this paper we extend the framework to moving formations through obstacle fields. We provide important metrics of performance that allow us to (a) compare the utility of different generalized force laws in artificial physics, (b) examine t...

In this paper, we introduce a class of triangulated graphs for algebraic representation of formations that allows us to specify a mission cost for a group of vehicles. This representation plus the navigational information allows us to formally specify and solve tracking problems for groups of vehicles in formations using an optimization-based approach. The approach is illustrated using a collec...

This paper presents the result of the implementation of a series of algorithms intended to be used for representing in most of the 3D geographic software, even Google Earth, the subsurface formations properties combining 2D charts or 3D plots over a 3D background, allowing everyone to use them, no matter the economic size of the company for which they work. Besides the existence of complex and ...

Variation in the mineral composition of rocks results in a change of their spectral response capable of being studied by imaging spectroscopy. This paper proposes the use of a low-cost handy sensor, a calibrated visible-very near infrared (VIS-VNIR) multispectral camera for the recognition of different geological formations. The spectral data was recorded by a Tetracam Mini-MCA-6 camera mounted...
