CurveLab-2.1.2
CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet
Transform in two and three dimensions.
For the 2d curvelet transform, the software package includes two distinct implementations:
the wrapping-based transform and the transform using unequally-spaced fast Fourier trans-
form (USFFT). Both variants are based on the Curvelet transform as described in ‘New
Tight Frames of Curvelets and Optimal Representations of Objects with Piecewise C2Sin-
gularities’, Comm. Pure Appl. Math. 57 (2004) 219-266. The implementation is also
discussed in detail in ‘Fast Discrete Curvelet Transforms’, Multiscale Model. Simul. 5
(2006), no. 3, 861-899. We advise users to become familiar with these references.
The two implementations diff er by the choice of spatial grid used to translate curvelets at
each scale and angle.(CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet Transform in two and three dimensions.

newton
Power flow studies, commonly known as load flow, form an important part of power system
analysis. They are necessary for planning, economic scheduling and control of an existing system as
well as planning its future expansion. The problem consists of determining the magnitudes and phase
angle of voltages at each bus and active and reactive power flow in each line.
In solving power flow problem, the system is assumed to be operating under balanced
conditions and a single-phase model is used. Four quantities are assumed at each bus. These are voltage magnitude v, phase angle , real power P, and reactive power Q.The Newton Raphson method of load flow analysis is an iterative method which approximates the set of non-linear simultaneous equations to a set of linear simultaneous equations using Taylor’s series expansion and the terms are limited to first order approximation.
