The goal of this thesis is to develop a new, fast, adaptive load flow algorithm that "automatically alternates" numerical methods including Newton-Raphson method, Gauss-Seidel method and Gauss method for a load flow run to achieve less run time. Unlike the proposed method, the traditional load flow analysis uses only one numerical method at a time. This adaptive algorithm performs all the computation for finding the bus voltage angles and magnitudes, real and reactive powers for the given generation and load values, while keeping track of the proximity to convergence of a solution.

Abstract:
In tunnel excavation, the use of rockbolts has long been a popular means of reinforcement in rock masses to prevent the rock opening from caving in. The idea has evolved from the earliest form of rockbolt made of wood to the more up-to-date form of pre-tensioned or grouted steel rockbolts. A major breakthrough in the design of rockbolt models was made by Aydan (1989). This rockbolt element was modelled in coupled form, with one sub-element representing the steel bolt, and the other sub-element the grout. This representation was necessary to model the complex action in the continuous rock mass

Tracking objects or people in an indoor environment has a wide variety of uses in many different areas, similarly to positioning systems outdoors. Indoor positioning systems operate in a very different environment however, having to deal with obstructions while also having high accuracy. A common solution for indoor positioning systems is to have three or more stationary anchor antennas spread out around the perimeter of the area that is to be monitored. The position of a tag antenna moving in range of the anchors can then be found using trilateration. One downside of such a setup is that the

Low-frequency noise is annoying and during periods of long exposure it causes fatigue and discomfort. The masking effect which low-frequency noise has on speech reduces speech intelligibility.

In some problems this factorization becomes prohibitive due to storage and time limitations. Iterative approaches are more interesting in these situations.

The work done in this thesis is to examine various methods for curve fitting. Linear least squares and non-linear least squares will be described and compared, and the Newton method, Gauss--Newton method and Levenberg--Marquardt method will be applied to example problems.<br>Syftet med denna uppsats är att beskriva och använda olika metoder för kurvanpassning, det vill säga att passa matematiska funktioner till data.

Nous avons développé une méthode d'approximation des signaux et systèmes à temps continu, optimale au sens des moindres carres. À partir de la seule connaissance de la transformée de Laplace rationnelle ou irrationnelle de la réponse, par exemple impulsionnelle ou indicielle d'un système initial, nous déterminons le meilleur modèle approche dont la réponse, soit la plus proche possible de celle du modèle original. Nous exprimons toujours le modèle approche sous forme d'une transformée de Laplace rationnelle. La qualité de l'approximation est mesurée à l'aide du critère d'erreur quadratique. La

Abstract:
Some well-studied infinite-state stochastic models give rise to systems of nonlinear equations. These systems of equations have solutions that are probabilities, generally probabilities of termination in the model. We are interested in finding efficient, preferably polynomial time, algorithms for calculating probabilities associated with these models. The chief tool we use to solve systems of polynomial equations will be Newton’s method as suggested by [EY09]. The main contribution of this thesis is to the analysis of this and related algorithms. We give polynomial-time algorithms for calculat

Abstract:
<p>In comparison to other basic arithmetic operations, such as addition, subtraction and multiplication,division is far more complex and expensive. Many division algorithms, except for lookup tables, rely on recursion with usually complex operations in the loop. Even if the cost in terms of area and computational complexity sometimes can be made low, the latency is usually high anyway, due to the number of iterations required. Therefore, in order to find a faster method and a method that provides better precision, a non-recursive polynomial-based algorithm was developed by the Department of El

Abstract:
This thesis deals with solutions of nonlinear regression problems using R programming language. The introductory theoretical part is devoted to familiarization with the principles of solving nonlinear regression models and of their applications in the program R. In both, theoretical and practical part, the most famous and used differentiator algorithms are presented, particularly the Gauss-Newton's and of the steepest descent method, for estimating the parameters of nonlinear regression. Further, in the practical part, there are some demo solutions of particular tasks using nonlinear regressio

Abstract:
La simulation et le contrôle des mouvements d'un robot manipulateur nécessitent la résolution des problèmes cinématiques et dynamiques. Une capacité de calcul insuffisante a toujours constitué l'obstacle majeur de la simulation et du contrôle en temps réel des mouvements d'un robot manipulateur. Il est unanimement reconnu que l'utilisation d'architectures informatiques parallèles est un facteur clé pour surmonter cet obstacle. L'objectif de ce travail est de déduire les caractéristiques essentielles puis de mettre en oeuvre une architecture hautement parallèle qui procure les améliorations sig
