The first work on this kind of systems is those of Anosov, Tzypkin and Emelyanov in the former USSR, or those of Hamel in France. This research made new great strides at the end of the Seventies when Utkin introduces the theory of the sliding mode. Currently, this technique knows a broad range of applications in very varied fields such as robotics, mechanics and the electro-technology. The algorithm by sliding mode control is classified in the monitoring systems with variable structure VSS (Variable System Structure in the Anglo-Saxon literature). This technique is based on the principle of reduction of the systems order and it concern linear and nonlinear systems. The principle of system with variable structure consists in bringing back, whatever the initial conditions, the point representative of the system evolution on a space surface (representing a set of relations, static, between the variables of state). ····· 1036120022

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book demonstrates the application of a robust technique for damping low frequency oscillations. The control is designed by extending the logic of SMA and integrating it with the LMI technique to develop a single-gain feedback controller that is capable of damping oscillations in large systems. It is an integrated form of control because it combines different controllers together so as to prevent any negative interaction between the individual controls. A 16-machine, 68-bus model of the New England-New York interconnected power system is used as the test case with DC lines and SVCs acting as the control. The proposed technique is then applied to an equivalent model of the WECC system developed in MATLAB and finally transferred to a larger and more detailed version created in PSLF. The controllers initially used for the WECC system are the two HVDC lines and an SVC. Three ESDs are then added to the model for the improvement of the control. The results indicate that the proposed technique provides adequate damping to the relevant modes of oscillations over a wide variety of operating conditions and that it can be easily applied to large and complex power system networks. ····· 1036119924

It is theoretically and practically observed that sometimes partitioning the problem space into more than two parts can give better performances. In this work we proposed that dividing the problem space into (n) number of parts can give better result.We organized the book as follows,in Chapter 2, we discussed Divide-and-Conquer algorithm and Closest-Pair problem. In Chapter 3, we reviewed previous works about Divide-and- Conquer algorithm to solve Closest-Pair problem. In Chapter 4, we present detailed version of the Basic-2 algorithm and give the correspondent proof of correctness as presented by Jos e C. Pereira & Fernando G. Lobo (2010). In Chapter 5, some previous proofs are given where is proven that 2-ary system is not the best choice for all the algorithms. The results in this chapter are based on [Kayk98].

From neuropsychological and literature point of view, it is clear that our artificial intelligence tools and architectures are lacking for human like capabilities in machines. Quantum mechanics is the physics of possibility due to its properties, also offers the opportunity to integrate these complex practices into more powerful and accurate methods by understanding human s mind more accurately and in a better way. Quantum sparse distributed memory provides considerably better performance and close to human s storage and retrieval capability in machines.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The work done here is designed to perform two tasks. Firstly the direction of motion of the object is detected and given to the user in visual form. Secondly the speed with which the object is moving is calculated in terms of pixels per frame. In order to achieve this first a set of images of the moving object is taken at regular time intervals. Then the motion is detected by finding the difference of the consecutive images. In order to calculate speed, first the segmentation is done of the images so that the different objects can be separated. Then on the basis of the area the desired region in the image (i.e. the object to be tracked) is separated from the others. In this case a ball has been used as the object. After separating the region the centroid of the region of interest is calculated. This is done for all the images collected. Once the centroid position of the region is found in all the images the coordinates are subtracted to find out the number of pixels the object has moved in the next frame. In this manner it can be calculated that how much pixels the object has traveled per frame in unit time. ····· 1036119807

Since its introduction however there arose so many controversial feelings on its performance throughout the world. What enhances the public enterprises in developing countries for privatization is their economic incapability and governments of these countries expressed their successes in implementing it. Researchers and economists are hence very busy in identifying the successes or failures of privatization. Irrespective of the elucidations and conclusions given by the governments of developing countries which have enjoyed from the privatization platform, most research findings showed privatization in these countries are alarming. The main objective of this study is therefore to identify and analyze the challenges, limitations and other scenarios of privatization so as to evaluate the post-privatization performance of privatized industrial establishments in Ethiopia. ····· 1036119748

A groundwater dam is constructed across stream which retards the natural groundwater flow of the system and stores water below ground surface to meet the demands during the period of scarcity. Groundwater is commonly available resources and the only permanent and safe source of water. The development of the groundwater basin and the concept of storing water in subsurface is an attractive alternate solution to the water shortage problems in arid areas. The capital cost for this kind of structure is relatively low.Shedi soil available in lateritic formation is investigated for considering, it as an alternative material for SSB. Composite soil is prepared by addition of clay to shedi soil at different proportions. Large scale hydraulic conductivity tests are carried out to determine optimal clay content for preparing composite soil. Large scale Hydraulic conductivity tests are also done by varying the thickness of SSB s. The suitability of different materials such as clay with river sand need to be investigated as an alternative material. ····· 1036119732

As with any emerging technology, user acceptance of new software and hardware devices is often difficult to measure and guidelines to introduce and ensure adequate and correct usage of such technologies are lacking. These problems have been tackled by the development of a new evaluation method focused on cognitive, affective and skill-based learning dimensions, and extended to the study of user performance, perceptions and memory in the context of procedural tasks training. The method significantly improves training evaluation time to 9 hours, and the number of users to 6. The method provides a more complete theoretical account of the mechanisms by which VT system design features and individual characteristics affect training outcomes, which should enable future research to systematically evaluate the effectiveness of a wide range of virtual training applications. ····· 1036119623

This approach differs from the traditional optimization approach that typically assesses alternative planning solutions by finding solutions with minimum total cost. Instead a separate capital cost is calculated for each solution, this ensures that the technical benefit of each solution is not obscured by the associated solution capital cost. By comparing the cost of each solution with the capital investment budget a most desirable solution can be determined. The key benefit of this approach is the ability to make strategic planning decision relating to the whole distribution network and also individual planning problems, this gives an overall microscopic view of all the network problems and the planned projects within the planning horizon period, which makes it easy to prioritize projects accordingly. ····· 1036119415
