STRATEGY FOR DESIGNING GEODETIC NETWORK WITH HIGH RELIABILITY AND GEOMETRICAL STRENGTH
"... ABSTRACT: The main design criteria in a geodetic network are precision, reliability and strength, and economy. The proper design of geodetic networks is an integral part of the geodesist's task. The main goal of this paper is to suggest a strategy for designing a geodetic network to meet high ..."

reliability and geometrical strength criteria. In this context, a real 2D deformation monitoring scheme has been selected to evaluate its design criteria. The results indicate that the perimeter of a geodetic network is relatively weaker than the middle. This means that the perimeter observations are usually

On linear variational surface deformation methods
"... This survey reviews the recent advances in linear variational mesh deformation techniques. These methods were developed for editing detailed high-resolution meshes, like those produced by scanning real-world objects. The challenge of manipulating such complex surfaces is three-fold: the deformatio ..."

Information-Geometric Measures as Robust Estimators of Connection Strengths and External Inputs
, 2009
"... Information geometry has been suggested to provide a powerful tool for analyzing multineuronal spike trains. Among several advantages of this approach, a significant property is the close link between information-geometric measures and neural network architectures. Previous modeling studies establis ..."

established that the first- and second-order information-geometric measures corresponded to the number of external inputs and the connection strengths of the network, respectively. This relationship was, however, limited to a symmetrically connected network, and the number of neurons used in the parameter
Using Geometric Complexity to Enhance the Interfacial Strength of Heterogeneous Structures Fabricated in a

A new multistage, multi-piece molding process is used to create heterogeneous polymer structures with geometrically complex interfaces consisting of rectangular and circular interlocking features. The structural integrity of these heterogeneous structures
A Geometric Approach to Device-Free Motion Localization Using Signal Strength
, 2010
"... In this work we describe and evaluate an approach to ac-curately infer the position in a building where human mo-tion occurs. Our approach does not require the humans to wear any type of device. Such passive mobility lo-calization is applicable in a wide variety of application domains, including tho ..."

We position human motion us-ing the change in standard deviation of the received sig-nal strength between stationary transmitters and receivers at known locations. Using a modest transmission rate of once per second, we localize the motion at 2
Pseudolite applications in positioning and navigation: Modelling and geometric analysis
, 2001
"... Pseudolites are an exciting technology whose potential can be explored for a wide range of positioning and navigation applications, either as a significant augmentation of spacebased systems, or as an independent system for indoor positioning. Compared with satellites in space, pseudolites usually h ..."
