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 …

Sketching in 3D : towards a fluid space for mind and body
… new type of computer-aided sketching tool for 3-dimensional designs. Sketching, as a process, has been used as an effective way to explore and develop ideas in the design process. However, when designers deal with volumetric designs in 3-dimensional space, current sketching means, including …

3D geographic model vs street view panorama a cognitive study on navigation in different Google maps representations
… have been invented to help people navigate in space. The different tools use different modes of representation as abstractions of 3-dimensional space. Two of the representations used in Google Maps, a modem wayfinding technology, are the 3D geographic model mode and the street view panorama …

Stratospheric scattering of radio waves and the Jicamarca radio telescope
… and turbulent mixing of the stratosphere. The 3-dimensional space spectrum of turbulent fluctuations, the mean wind velocity, and the root-mean-square velocity fluctuations are directly related to the autocorrelation function of the scattered signals. The theory and mechanisms of stratospheric …

Autonomous Collision Avoidance for a Teleoperated UAV Based on a Super-Ellipsoidal Potential Function
… of an unmanned aerial vehicle (UAV) in a 3-dimensional space. In the design of the SEPF, we have the full control over the shape and size of the potential function. In our proposed approach, a teleoperated UAV can not only autonomously avoid collision with surrounding objects but also track …

Three-dimensional image reconstruction of skeletal tissue from computed tomography
… we develop a simple process for the three dimensional image reconstruction of the human knee, starting from computed tomography scans. Designing a digital image processing technique which successfully separates the bone from the surrounding flesh and muscle tissue is the main focus of the …

Path planning and position control and of an underactued [sic] electromagnetic formation flight satellite system in the near field
… electromagnetic actuators (coils) on multiple spacecraft to produce relative (internal) forces in order to control the relative position and orientation of the spacecraft. This thesis demonstrates the ability to experimentally generate the relative internal electromagnetic forces in a short …

Task-orientated multimodal feedback system for the rehabilitation of the upper limb
… how to use an arm exoskeleton operating in 3-Dimensional space in conjunction with a multimodal software environment forpotentially helping stroke patients regain functional independence by relearningactivities of the daily living. More specifically, the software would provide a way …

Higgs-Portal and Z'-Portal Dark Matters in Brane-World Cosmologies
… the WIMP DM model within the framework of 5-dimensional brane-world cosmology. In this setup, our familiar 3-dimensional space is realized as a hyper-surface embedded in a 4-dimensional space. Within this context, all SM and DM fields are confined to the hyper-surface, while the graviton …

Nonlinear Models and Geometric Structure of Fluid Forcing on Moving Bodies
… Within this model, all trajectories in velocity space collapse to a 1-dimensional invariant manifold known as the terminal velocity manifold. This work presents methods to identify the terminal velocity manifold, investigates its properties, and extends it to a 2-dimensional invariant manifold in …

The constrained discrete-time state-dependent Riccati equation technique for uncertain nonlinear systems
… by applying this scheme to problems of spacecraft formation orbit reconfiguration under limited performance on thrusters. Simulation results demonstrate the efficacy and reliability of the proposed CD-SDRE. The CD-SDRE technique is further investigated in a case where there are …
