TUNING OF PID CONTROLLER OF INVERTED PENDULUM USING GENETIC ALGORITHM P. Kumar

by O. N. Mehrotra, J. Mahto
"... The paper presents two different ways of mathematical modeling of Inverted Pendulum. A Proportional-Integral-Derative (PID) controller is designed for its stabilization. Some reference stable system is selected after designing of PID controller to optimize different types of error using Genetic Algo ..."

Algorithms. The proposed system extends classical inverted pendulum by incorporating two moving masses. A tuning mechanism is implemented by genetic algorithm for optimizing different gains of controller parameter. Also, different performance indices are calculated in MATLAB environment. This paper exhibits

Comparison of User Performance in Mixed 2D-3D Multi- Display Environments

by Abhijit Karnik, Tovi Grossman, Sriram Subramanian
"... Abstract. Stereoscopic displays and volumetric 3D displays capable of delivering 3D views have in use for many years. These standalone displays have been investigated in detail for their impact on users ’ viewing experiences. Effects like aesthenopia and nausea are well-known for flat-screen based s ..."

stereoscopic displays. However, these devices have not been tested in the context of multidisplay environments (MDEs). The performance cost of repetitive switching between a 3D (stereo or volumetric) display and a standard 2D display are not known. In this paper, we perform a thorough user study where we

Sensitivity Analysis of the Optimal Parameter Settings of an LTE Packet Scheduler

by I. Fernandez Diaz, R. Litjens, D. C. Dimitrova, K. Spaey
"... Abstract—Advanced packet scheduling schemes in 3G/3G+ mobile networks provide one or more parameters to optimise the trade-off between QoS and resource efficiency. In this paper we study the sensitivity of the optimal parameter setting for packet scheduling in LTE radio networks with respect to vari ..."

Although, in some cases, efficiency gains of about twenty percent can be achieved by proper tuning of the scheduling parameters, the overall view

The importance of scale in object-based mapping of vegetation parameters with hyperspectral imagery.

by Elisabeth A Addink - Photogrammetric Engineering & Remote Sensing , 2007
"... Abstract In recent years, object-oriented image analysis has been widely adopted by the remote sensing community. Much attention has been given to its application, while the fundamental issue of scale, here characterized by spatial object-definition, seems largely neglected. In Introduction Remote ..."
Abstract - Cited by 17 (3 self) - Add to MetaCart
Remote sensing data offer a rich information source on vegetation parameters, which may be needed as input to models describing processes at the Earth's surface (Cohen When the vegetation is considered as part of a hierarchical scene model A solution could be found in irregularly shaped

Aqueous CSD approach for the growth of novel, lattice-tuned La x Ce 1Àx O d epitaxial layers †

by Vyshnavi Narayanan , Petra Lommens , Klaartje De Buysser , Danny E P Vanpoucke , Ruben Huehne , Leopoldo Molina , Gustaaf Van Tendeloo , Pascal Van Der Voort , Isabel Van Driessche
"... Lanthanum-cerium oxide (LCO) films were deposited on Ni-5%W substrates by chemical solution deposition (CSD) from water-based precursors. LCO films containing different ratios of lanthanum and cerium ions (from CeO 2 to La 2 Ce 2 O 7 ) were prepared. The composition of the layers was optimized towa ..."

Nonlinear Color Space and Spatiotemporal MRF for Hierarchical Segmentation of Face Features

by Marc Liévin, Franck Luthon - in Video, IEEE Transactions on Image Processing 13 , 2004
"... Abstract—This paper deals with the low-level joint processing of color and motion for robust face analysis within a feature-based approach. To gain robustness and contrast under unsupervised viewing conditions, a nonlinear color transform relevant for hue segmentation is derived from a logarithmic m ..."

Relevant face regions are segmented without parameter tuning. The accuracy of the label fields enables not only face detection and tracking

"... A new nonlinear Petrov-Galerkin approach has been developed for Proper Orthogonal Decomposition (POD) Reduced Order Modelling (ROM) of the Navier-Stokes equations. The new method is based on the use of the cosine rule between the advection direction in Cartesian space-time and the direction of the g ..."
