für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Understanding the biomechanical factors in orthodontics is important in order to improve the overall effectiveness of actual clinical treatment. An accurate method to study the three-dimensional(3D)force systems and the resulting movements of teeth during orthodontic treatment is needed along with the understanding of the material properties of any orthodontic wire. Until recently, most of the orthodontic biomechanics literature was limited to two-dimensional experimental studies. Recent advances in three-dimensional computer modeling have also been developed but have been limited to the manual control of tooth movement. Therefore, this book details how a cost-effective orthodontic wire tester that is capable of three-dimensional measurements and analyses of orthodontic force systems was developed. The successful development of the orthodontic wire tester, including its computer protocols, will allow orthodontists to determine, with great accuracy, the forces and torques acting at precise locations on the teeth. It will also allow for future simulation research on new and existing orthodontic clinical applications by orthodontists and biomedical engineers. ····· 1036119264

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In this project we have developed a parametric inversion algorithm to simultaneously determine the horizontal conductivities, vertical conductivities, bed boundary positions and dip angle from tri-axial induction logging data in anisotropic layered media. The inversion algorithm was first solved in an infinite homogeneous medium to obtain a good initial-guess model.The variance-based method was used to locate initial bed boundaries. The inversion problem has been solved by the method of least squares using the constrained Gauss-Newton minimization approach. Two globally convergent strategies based on a robust and efficient version of the Levenberg-Marquardt algorithm were implemented. The line-search algorithm was incorporated which guarantees a reduction in the cost function after each iteration.In the inversion algorithm a non-linear transformation has been incorporated to impose bounds on the unknown model parameters. To speed up the computation, the Jacobian was determined analytically for the whole space inversion. Boundary-merger routines were added to further accelerate the inversion procedure. The results show that the reconstructed model is consistent with the true model. ····· 1036118920

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray One of the measures to achieve sustainability in urban transportation is to encourage bus transit by assigning priority to it through provision of exclusive bus lanes. The subject matter of this book is about formulating an appropriate methodology to study and quantify the possible impact of provision of exclusive bus lane under heterogeneous traffic conditions. The impact of introduction of exclusive bus lane is measured in terms of increase in speed of bus due to provision of exclusive lane and change (reduction) in speed of other categories of motor vehicles, due to the consequent reduction in road space, for a wide range of traffic volume, using micro simulation technique. An attempt has also been made for justifying provision of exclusive bus lane by apportioning of road space based on the number of persons (travellers) making use of the available road space. This study is also concerned with estimation of the probable shift of the personal vehicle users to bus due to increase in its level of service. It is hoped this book will be a useful reference to graduate students, researchers, and practitioners interested in planning of bus priority measures. ····· 1036118707

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The fundamental goal of multi-agent robotics is simple: how to create control laws and behaviors that, when executed by each individual robot, some desirable global behavior emerges. The global behavior may range from something as simple as the robots meeting at a single point, to something as complex as a collective search and rescue mission. Our research focuses on one of the more fundamental issues in multi-agent, mobile robotics: the formation control problem. The idea is to create controllers that cause robots to move into a predened formation shape. This is a well studied problem for the scenario in which the robots know in advance to which point in the formation they are assigned. In our case, we assume this information is not given in advance, but must be determined dynamically. This thesis presents an algorithm that can be used by a network of mobile robots to simultaneously determine ecient robot assignments and formation pose for rotationally and translationally invariant formations. This allows simultaneous role assignment and formation sysnthesis without the need for additional control laws. ····· 1036118252
