The brain is a network and our intelligence depends in part on the efficiency of this network. The network of adolescents differs from that of adults suggesting developmental changes. However, whether the network changes over time at the individual level and, if so, how this relates to intelligence, is unresolved in adolescence. In addition, the influence of genetic factors in the developing ne...

Effective flow feature extraction enables users to explore complex flow fields by reducing visual clutter. Existing methods usually use streamline segmentation as a preprocessing step for feature extraction. In our work, features are directly extracted as a result of streamline segmentation. In order to achieve this, we first ask users to specify desired features by manually segmenting a few st...

The application of state-of-the-art history matching methods to large heterogeneous reservoirs is hampered by two main problems: (1) reservoir models should be constrained jointly to dynamic data and a large variety of geological continuity information, (2) CPU demand should not be prohibitive for large models. This paper proposes a method contributing to alleviating these two main concerns. By...

Combining finite element together with particle methods provide one of the best compromise for solving transport problem in porous media. Saturated or non-saturated flows are determined by boundary condition and the media permeability. For real terrain, permeability can consist in various almost constant and imbricated zones with complex shapes. Thus, it is of some interest that the boundary be...

The grand piano action is modeled as a set of four rigid bodies using Kane’s method. Computerized symbol manipulation is utilized to streamline the formulation of the equations of motion so that several models can be considered, each of increasing detail. Various methods for checking the dynamical model thus derived are explored. A computer animation driven by simulation of the equations of mot...

Diffusion magnetic resonance imaging (dMRI) and tractography provide means to study the anatomical structures within the white matter of the brain. When studying tractography data across subjects, it is usually necessary to align, i.e. to register, tractographies together. This registration step is most often performed by applying the transformation resulting from the registration of other volu...

Efforts in the electronic grocery shopping, i.e. e-grocery business, focus especially on the physical distribution of the goods. For example, in the USA there are several e-grocery service providers with various operating concepts and offering various service levels. The home delivery concept of Streamline is based on a reception box at the customer’s garage or home yard enabling unmanned recep...

To analyze and understand the growing wealth of scientific data, complex workflows need to be assembled, often requiring the combination of looselycoupled resources, specialized libraries, distributed computing infrastructure, and Web services. However, constructing these workflows is a non-trivial task, especially for users who do not have programming expertise. This problem is compounded for ...

Curves in space are diicult to perceive and analyze, especially when they form dense sets as in typical 3D ow and volume deformation applications. We propose a technique that exposes essential properties of space curves by attaching an appropriate moving coordinate frame to each point, reexpressing that moving frame as a unit quaternion, and supporting interaction with the resulting quaternion ...

In the first study, Dr. Alexander Lembcke and colleagues at Charitè Medical University in Berlin compared a lowand a standard-dose contrast protocol in 60 consecutive patients with body weights ranging from 60 to 80 kg. Thirty of them received a 35-mL dose of contrast injected at 7.5 mL/sec (group A), while the remainder got a 70-mL dose injected at 5 mL/sec (group B). All patients underwent au...
