Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematical optimization, the Rosenbrock function is a non-convex function used as a performance test problem for optimization algorithms. It is also known as Rosenbrock''s valley or Rosenbrock''s banana function. The global minimum is inside a long, narrow, parabolic shaped flat valley. To find the valley is trivial. To converge to the global minimum, however, is difficult. It is defined by f(x, y) = (1-x)^2 + 100(y-x^2)^2 .quad. It has a global minimum at (x,y) = (1,1) where f(x,y) = 0. A different coefficient of the second term is sometimes given, but this does not affect the position of the global minimum. Two variants are commonly encountered. One is the sum of N / 2 uncoupled 2D Rosenbrock problems, f(x_1, x_2, dots, x_N) = sum_{i=1}^{N/2} left[100(x_{2i-1}^2 - x_{2i})^2 + (x_{2i-1} - 1)^2 right]. This variant is only defined for even N and has predictably simple solutions. A more involved variant is f(x) = sum_{i=1}^{N-1} left[ (1-x_i)^2+ 100 (x_{i+1} - x_i^2 )^2 right] quad forall xinmathbb{R}^N.

To achieve high well production and improve accessibility of oil reservoirs in complex locations, Directional Steering Systems (DSS) is used for drilling wells in Oil and Natural Gas (ONG) industry. In this work, a directional driller consisting of 4 motors is investigated both in its theoretical modeling and control technique. We investigate several directions for improving the model. First investigated approach is for optimization of the system using optimal control technique like Interior Point Optimization. The optimization procedure determines the drilling parameters to minimize the drilling time and the deviation from the planned trajectory. The control is updated at equal distance intervals. The second approach is to develop a Control techniques, like MPC in order to improve the tracking performance of the model. The control commands include torque of each of the 4 motors. The control is updated at regular time intervals. MPC and Interior Point Optimization techniques are compared and results are drawn which give an insight about the best method to be adopted in controlling the system.

Quadrilateral Surface Mesh Generation for Anima...

Besides triangle meshes, quadrilateral meshes are the most prominent discrete representation of surfaces embedded in 3D. Especially in sophisticated applications like for instance animation and simulation, they are often preferred due to their tensor-product nature, which induces several practical advantages. In contrast to their wide area of application, the available generation algorithms for high-quality quadrilateral meshes are still nonsatisfying compared to their triangle mesh counterparts. The main reason consists in the intrinsically more difficult topology, which requires global instead of local considerations.This thesis is devoted to novel algorithms that are specifically designed for the practical requirements in animation and simulation. First we will discuss important quality criteria, stemming from these applications. It turns out that, although the goal of both application areas is quite diverse, the quality criteria, which characterize a high-quality quad mesh, are identical. Apart from topological regularity, applications benefit from quadrilaterals with low distortion, well chosen curvature alignment to achieve good approximation and a coarse patch-structure in order to enable powerful mapping techniques as well as multi-level solver.Based on mixed-integer optimization and graph theory we propose carefully designed algorithms that are able to generate high-quality quadmeshes with the aforementioned properties in a fully automatic manner. Furthermore, the designer or engineer is still equipped with maximal control by the possibility of interactively influencing the automatic solution by means of additional high-level constraints.
