The notion of simultaneous manufacturing of prismatic parts has been conceived in this work to improve the system output in both cost and time frame. The computational prowess of DNA algorithm in preliminary graph based combinatorial optimization has been utilized to resolve the complexities of the proposed Integrated Process Planning and Scheduling (IPPS) framework. Further, the inherently parallel search strategy and structured architecture used in DNA algorithm meets the implementation requirements of IPPS. Being first of its kind attempt, the proposed strategy has first been tested over standard test functions, thus establishing its superiority in numerical optimization. Thereafter, its application to four integrated process planning and scheduling problems (three benchmarks and one simulated) with real sized data authenticate the robustness of the proposed solution methodology. ····· 10361115313

To accomplish this task, the text within images and videos can be a relevant key. In this work we focus on recognizing the content of the text and we assume that the text box has been detected and located correctly. We focused on a particular machine learning algorithm called convolutional neural networks (CNNs). These are networks of neurons whose topology is similar to the mammalian visual cortex. CNNs were initially used for recognition of handwritten digits. They were then applied successfully on many problems of pattern recognition. We propose in this work a new method of binarization of text images, a new method for segmentation of text images, the study of a convolutional neural network for character recognition in images, a discussion on the relevance of the binarization step in the recognition of text in images based on machine learning methods, and a new method of text recognition in images based on graph theory. ····· 10361115265

Vehicle dynamics coupled with liquid fuel slosh dynamics represents a broder class of underactuated systems. This coupled nonlinear system has been considered for the development of output feedback control using sliding modes. A sliding mode control (SMC) is one of the robust control approaches which yields robust performance against model inaccuracies and uncertainties. Design of SMC includes design of the hyperplane to yield the desired closed-loop performance and the controller synthesis to confine the states on the designed hyperplane. This book addresses novel approaches of designing the hyperplane together with the synthesis of the appropriate control law for the slosh problem in continuous and discrete both. Proposed state based control algorithms are extended for output feedback control using sliding mode high gain observer. Discrete sliding mode observer and a fast output feedback techniques are also illustrated for the development of discrete output feedback control. Experimental validation of few of the algorithms is also presented. ····· 10361115244
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book introduces new methods for tuning two dynamical classes of windupless pole assignment controllers. Increased reliability of the windupless controller tuning is derived from the fact that they try to take account of the natural distribution of dynamical terms within the control loop. In addition, they follow inevitable constraints imposed on the control signal. The developed controllers, presented here as minimum time pole assignment controllers, are primarily derived for the single and double integrator plant models. Considering models based on the 1st or 2nd order system the controller design guarantees a double or a tripple real dominant closed loop pole. The poles of the controller are adapted according to delays present in the control loop. The controller designs enable to consider the influence of elementary parasitic time delays (transport delay - dead time or accumulative delay - time constant) on controller setting. Since the controller structure remains fixed, i.e. it doesn`t change its form and order due to the identified time delays, the controllers can be associated with the well-known group of parameter-optimized controllers. ····· 10361115202

This is a very difficult task and we propose an appropriate but not avoidably complex solution using a vision based perception system and a behaviour based (re)action system. Since we could not use a real robot and for general testing purpose, we developed a real mono camera based vision acquisition system and a virtual acting 3D environment for mobile robot navigation. We developed a virtual environment called `VIMRINNE` (Virtual Interface for Mobile Robot Instant Navigation in Natural Environment) which provides a framework for study, experimentation and development of mobile robot applications in 3D VR. This work includes the following contributions: The definition of a software architecture allowing modularity, extensibility, and near real time processing We will demonstrate the capabilities of our project through some experiments and evaluations that show the interest of our approach.

Offshore wind turbines are primarily exposed to overturning moment, arising from both the aerodynamic and hydrodynamic sources. So far, no design standard provides analytical methods to account for this kind of load transfer through the grouted connection. The intention of this paper is to demonstrate that analytical estimations can be formulated that reasonably agree with both experimental and numerical analyses of such connections. It is based on a theoretical approach, involving both theory of elasticity and finite element methods. The analytical approach involves various aspects of vector calculus, boundary value problems, potential energy formulations, harmonic functions and solution methods for 1, 2 and 3-dimmensional systems of equations.

Since then, the number of structural systems addressed in seismic codes has dramatically increased. As a result, the seismic response characteristics of many systems, and their ability to meet seismic design performance objectives, are both untested and unknown.In an attempt to address these issues, the Applied Technology Council (ATC) was commissioned by Federal Emergency Management Agency (FEMA) under the ATC-63 Project to develop a methodology for quantitatively determining global seismic performance factors for use in seismic design.Though this Methodology is originally recommended for use with model building codes and resource documents to set minimum acceptable design criteria for standard code approved seismic force resisting systems, in this report it is used as a basis for evaluation of a steel moment frame designed in 1970`s to achieve intended seismic performance objectives.This work should help students and professionals interested in seismic analysis of structures. ····· 10361114966

Mammography is a method commonly used for detection of breast cancer. A mammogram is a very high spatial resolution X-ray of breast. The mammograms need to be screened for abnormal and possibly dangerous lesions. Computer-aided diagnosis has been an active area of research to detect abnormalities in a mammogram automatically. The focus of this thesis is on automatic detection of microcalcifications in a mammogram using fuzzy image processing. Microcalcification is one of the earliest signs of breast cancer, which is sometimes hard to detect due to its small size, low contrast and blurred boundary. The fuzzy algorithms developed in this work analyse an image at pixel level, detect the abnormalities and identify the edges of abnormalities using fuzzy operators. The developed fuzzy system is applied to a set of high-resolution mammograms in order to validate its performance. The results clearly demonstrate the feasibility and effectiveness of the proposed approach. ····· 10361114896

As the analyst solves this problem, the decision maker and the implementer have to coordinate with the analyst for taking up a decision on a successful strategy for implementation. Such a complex problem of vagueness and uncertainty can be handled by the theory of fuzzy logic.In this book, a new fuzzy logic based methodology using a specific membership function, named as modified S-curve membership function is proposed. The modified S-curve membership function is first formulated and its flexibility in taking up vagueness in parameters is established by an analytical approach.The usefulness of this modified S-curve membership function is further established using a real life industrial production planning of a chocolate manufacturing unit. ····· 10361114872

This is reflected in the great amount of papers published on scientific magazines trying to solve the traffic assignment and trip matrix estimation problems. This fact shows the difficulty to elaborate an effective model able to reproduce the real behaviour. These models use several data inputs (prior trip matrix, link counts, etc.), only from a subset of the problem variables, and its size will depend on the available budget. One problem of these models is the high number of possible solutions which is usually solved by finding one where the model results and the real data match up. Nevertheless a model does not have to reproduce only the real data, but also all the variables. Therefore the problem must consist of reproducing the reality in a precise form with minimum cost. The aim of this work consists of proposing new models, which allow us to update the traffic flow predictions from a small subset of real data. To this end, a Gaussian Bayesian Network is used, and so, probability intervals are obtained to get an idea of the associated uncertainties. ····· 10361114862
