Intelligent runtime tuning of parallel applications with control points
… or structure of the program through one or more control points. Control points are a novel type of tunable parameter provided by an application wherein it exposes tunable knobs and information about the behavioral effects expected to occur as each knob is varied in each direction. This behavioral …

Mutagenesis investigations into proton transfer pathways and control points in respiratory complex I
… homeostasis, positioning complex I at a key control point in aerobic metabolism. Despite extensive structural characterisation, the mechanism of complex I catalysis remains poorly understood, with proposed mechanisms lacking both molecular detail and biochemical support. In this thesis the …

Identifying control points of excessive nitrate load in a pastoral catchment to support lake management
… of specific sources and delivery mechanisms controlling contaminant transport over various spatial and temporal scales. This study systematically investigated nitrate dynamic flow from a small pastoral catchment into a eutrophic lake located in the central plateau of New Zealand’s North …

Deep localized hyperthermia with ultrasound-phased arrays using the pseudoinverse pattern synthesis method
… pattern synthesis method capable of precisely controlling the power deposition level at a set of control points in the treatment volume using ultrasound phased arrays. This method, called the pseudoinverse pattern synthesis method, reduces the pattern synthesis problem to one of estimating the …

Single digital-photo correction for a GIS application and error analysis
… for a GIS application was investigated by control and test data from digital photos and USGS 1:24,000 topographic maps and by USGS 7.5-minute DEMs of two study areas, Prentiss, North Carolina and Blacksburg, Virginia. The collinearity equations were used to remove geometric errors caused by …

LOW-COST PHOTOGRAMMETRY SYSTEM FOR GEOREFERENCED STRUCTURE FROM MOTION
… SFM relies on having a large number of ground control points that were surveyed ahead of time as the main source of geo-referenced data. The deployment and survey of ground control points are time consuming, and sometimes infeasible due to environmental constraints. A better solution is to …

Three-dimensional sketch tool
… is its requirement for the precise input of control points to establish three-dimensional objects and scenes. This heavy demand for precision makes the current technology too cumbersome to use during the early stages of design, which is inherently imprecise. Alternatively, a tool that allows …

Rational Cubic B-Spline Interpolation and Its Applications in Computer Aided Geometric Design
… of the flexibility that the weights and the control points provide, NURBS have recently become very popular tools for the design of curves and surfaces. If the weights are positive then the NURB will lie in the convex hull of its control points and will not possess singularities. Thus it is …

Form processing with the Hough transform
… is feature/knowledge based. Two methods for control points detection are discussed; one implements template matching for finding frame corners. The second approach is based on detection of line crossings via the analysis of the parameter space of the HT. Detected control points are used to …

Automatic Updating of Cartographic Databases
… data file to an existing file by means of survey control points that are included in both files. The two digital maps may have different scales, different coordinate systems, and no identifying cartographic labels. In the absence of such survey control points, well-defined points in polygonal …

Shape Optimization of Annular Combustors with an Open Source Parallelized Thermoacoustic Helmholtz Solver
… of the three-dimensional geometry with NURBS control points. We apply two different strategies, perpendicular boundary movements and control point perturbations, to implement shape changes proportional to these shape derivatives. With NURBS, we apply symmetry-preserving and symmetry-breaking …

A vortex-lattice method for Delta wing aerodynamics
… also indicated that fewer cosine distribution control points predict pressures as well as the use of a larger number of uniform distribution control points. The numerical results for wings with LEVFs show good agreement with experimental data away from the trailing edge. This may be due to the …

Arbitrary Degree T-Splines
… similar to NURBS, that allows partial rows of control points. Up until now, T-Splines have only been formally defined for the degree three case. This paper extends the definition to support all odd, even, and mixed degree T-Spline surfaces, making T-Splines a proper superset of all standard …

A Parametric Method of Perspective Alignment and Color Correction for Skin Lesion Imaging
… of rigid and parametric methods, using invariant control points as landmarks and inferring the global color variation from the color reference.</p> <p>The proposed geometric rectification and color correction methods are related with a fiducial mark design which provides control points and color …

Electromagnetics in characterizations
… By incorporating the information of the ground control points in the height inversion process, the initial estimation of the baseline parameters based on the satellite state vectors and the commonly used high order polynomial fitting can be improved. In this study, a simulated interferogram of a …

Automated Manufacture of Spinal Instrumentation
… the current SIBP uses a set of three dimensional control points that represent the desired contour of the rod. These control points are translated into manufacturing inputs that control the SIBP. The control application for the SIBP contains local and global feedback routines that correct for any …

The Potential of a Low Resolution Digital Camera in Close-Range Photogrammetry
… applications. The algorithms and softwares for control point measurement, conjugate epipolar lines computation and digital image correlation were developed. An experimental study was conducted with two GE TN2500, 244 x 248 pixels, CID digital/analog cameras for the mapping of a small object. The …

AUTOMATIC DETECTION OF FACIAL FEATURES FOR 3D MODEL BASED CODING APPLICATIONS
… using 3D model based coding. A selected set of control points of the face is transmitted to the remote terminal instead of sending video signal. In order to extract this set of control points a predefined 3D generic wire frame model is used. In this project, feature points of facial image for 3D …
