Buch. Condizione: Neu. Neuware - The last few decades have witnessed tremendous developments in nonlinear control theory. One of the most important of these is the model-based method of feedback linearisation in which a nonlinear system is transformed into a linear system by means of state feedback and nonlinear transformations. After feedback linearisation, a system can be dealt with by linear controller design. The extension of these techniques to include MIMO systems allows for the further simplification of controller design by decoupling the system. Strategies for Feedback Linearisation demonstrates this powerful technique in the light of research on neural networks which allow the identification of nonlinear models without the complicated and costly development of models based on physical laws. Dynamic or recurrent neural networks have inherent properties that allow them to approximate nonlinear dynamic systems. Strategies for the identification of nonlinear systems using such neural networks are presented in this monograph together with the use of such models for the design and application of input-output linearisation and decoupling methods. Strategies for Feedback Linearisation is written to serve academic and industrial researchers in non-linear control and system identification and practising control engineers interested in their application to real-world industrial systems. The reader will gain a balanced view of theoretical and practical issues: relevant mathematical proofs are provided as are case studies illustrating design and application issues.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a unique book in that it brings together the two key investigative techniques in Gynaecology and Obstetrics, namely ultrasound and endoscopy. So often in the past they were regarded by their exponents as rival techniques but it is now recognised that they are complementary to each other. Consequently future trainees in endoscopy should become efficient in transvaginal sonography and vice versa. Ultrasound can be used to study the morphology of the pelvic organs such as the endometrium, myometrium and ovaries, and being non-invasive, safe and convenient can be repeated as often as is deemed necessary to monitor changes over time; for example in the investigation of the infertile woman the development of the dominant follicle, the maturation of the endometrium and the formation of the corpus luteum can be documented throughout the menstrual cycle while growth of ovarian cysts can be precisely measured to determine the need for surgery. A seldom-mentioned strength of the ultrasound examination is its interactive quality, for example by performing abdominal palpation during the scan, the mobility of the uterus and ovaries can be assessed. Also the images as they appear can be shown to the patient to aid understanding. Ultrasound can also determine function and the use of Doppler has been used for example to access endometrial receptivity, follicular maturity and the likelihood of malignancy in the endometrium or ovary. 372 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Laminated Composite Plates and Shells presents a systematic and comprehensive coverage of the three-dimensional modelling of these structures. It uses the state space approach to provide novel tools for accurate three-dimensional analyses of thin and thick structural components composed of laminated composite materials. In contrast to the traditional treatment of laminated materials, the state space method guarantees a continuous interfacial stress field across material boundaries. Other unique features of the analysis include the non-dependency of a problem's degrees of freedom on the number of material layers of a laminate. Apart from the introductions to composite materials, three-dimensional elasticity and the concept of state space equations presented in the first three chapters, the book reviews available analytical and numerical three-dimensional state space solutions for bending, vibration and buckling of laminated composite plates and shells of various shapes. The applications of the state space method also include the analyses of piezoelectric laminates and interfacial stresses near free edges. The book presents numerous tables and graphics that show accurate three-dimensional solutions of laminated structural components. Many of the numerical results presented in the book are important in their own right and also as test problems for validating new numerical methods. Laminated Composite Plates and Shells will be of benefit to all materials and structural engineers looking to understand the detailed behaviour of these important materials. It will also interest academic scientists researching that behaviour and engineers from more specialised fields such as aerospace which are becoming increasingly dependent on composites. 292 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Safety in industrial process and production plants is a concern of rising importance but because the control devices which are now exploited to improve the performance of industrial processes include both sophisticated digital system design techniques and complex hardware, there is a higher probability of failure. Control systems must include automatic supervision of closed-loop operation to detect and isolate malfunctions quickly. A promising method for solving this problem is 'analytical redundancy', in which residual signals are obtained and an accurate model of the system mimics real process behaviour. If a fault occurs, the residual signal is used to diagnose and isolate the malfunction. This book focuses on model identification oriented to the analytical approach of fault diagnosis and identification covering: choice of model structure; parameter identification; residual generation; and fault diagnosis and isolation. Sample case studies are used to demonstrate the application of these techniques. 300 pp. Englisch.…
