Planning Practical Paths in High-Dimensional Space
… in the environment, which is known to be PSPACE-complete in the robot's DOF. As a consequence heuristic sampling-based approaches have been developed to solve high-dimensional real-world path planning problems. A shortcoming of the current sampling-based algorithms is that they can obtain …

Laptop Improvisation in a Multi-Dimensional Space
… of the argument is that by creating a multi-dimensional environment of Sonic Vector Spaces (see page 17) and implementing a method for quickly traversing that environment, a performer is able to create enough information flow to achieve laptop virtuosity. At the same time, traversing this …

Numerical relativity in higher-dimensional space-times
… To understand the non-linear regime of higher dimensional general relativity, such as that involved in the merger of black holes, we use numerical relativity to solve the Einstein equations. In this thesis we develop and demonstrate several diagnostic tools and new initial data for use in …

Visualization of spatio-temporal data in two dimensional space
Spatio-temporal data is becoming very popular in the recent times, as there are large number of datasets that collect both location and temporal information in the real time. The main challenge is that extracting useful insights from such large data set is extremely complex and laborious. In this …

Joint Face Detection and Tracking in Three-Dimensional Space
Visual detection and tracking of faces in complex scenes is a very interesting and challenging problem. In general, real human-computer interaction scenarios present significant challenges to most face detection and tracking algorithms, for example, partially occluded and low-resolution faces, as …

A framework for promotion analysis in multi-dimensional space
… for promoting a given object in a multi-dimensional space by leveraging object ranking information. The key observation is that most objects may not be highly ranked in the global space, where all objects are compared by all aspects; in contrast, there often exist interesting and …

Topological solitons of the nonlinear Dirac equation in 2+1 dimensional space time
… with the primary focus being on planar, (2 + 1) dimensional nonlinear Dirac models.We study a (2 + 1) dimensional extension of the (2 + 0) dimensional reduction the complex sine-Gordon. This is a tachyonic nonlinear Dirac equation whose linear part can be reduced to the imaginary mass …

Comparative Study of Dimension Reduction Approaches With Respect to Visualization in 3-Dimensional Space
… insight of it. It is possible to convert high-dimensional data to low-dimensional data using different techniques, this dimension reduction is important and makes tasks such as classification, visualization, communication and storage much easier. The loss of information should be less while …

A Multigrid Acceleration for an ADI Finite Difference Method for Two-Dimensional Space Fractional Diffusion Equations
… While a lot of methods are dealing with one dimensional problem, in this paper we develop a multigrid acceleration for spacial fractional diffusion equations in two space dimensions. The method only requires computational work of O(N logN) and memory of O(N) per time step, while retaining the …

Conformal Flight Path Symbology for Head-Up Displays: Defining the Distribution of Visual Attention in Three-Dimensional Space
… was found to be more widely distributed in X-Y space when the pilots were flying with the conformal, tunnel-in-the-sky as compared to the partially conformal ILS (instrument landing system) symbology set. There was little evidence that the air-based navigation displays were supporting divided …

Visual exploration of multivariate data in breast cancer by dimensional reduction
… improvement of computational techniques based on dimensional data reduction for the visual exploration of DCE-MRI and DNA microarray data in breast cancer. Algorithms for dimensional data reduction aim to compute low-dimensional projections of high-dimensional data while best preserving the data …

A Probabilistic Approach To Multiple-Instance Learning
… represented in an instance induced (very high dimensional) space. A parametric stochastic neighbor embedding method is applied to learn a mapping that projects bags into a 2-d or 1-d space. Class conditional probability densities are then estimated in this low dimensional space via kernel …

Appearance based object recognition using independent component analysis
… been a renewed interest in appearance based 3-dimensional object recognition. All possible views of an object define its workspace, known as visual workspace. This workspace is coarsely sampled and projected onto a lower-dimensional space and represented as workspace manifold. The …
