In recent years, Pan sharpening methods are viewed as an effective tool to analyze multiband remote sensing images. In this paper a novel substitutive Pan sharpening method using PCA and contourlet transform is proposed. The proposed method provides novel tradeoff solution between the spectral and spatial fidelity and preserves more detail spectral and spatial information. Also, new substitution based image fusion rules are proposed. Proposed method is applied on registered Panchromatic and Multispectral images and simulation results are compared using standard image fusion parameters. The simulation results of proposed method also compared with four different standard Pan sharpening methods available in literature. It has been observed from simulation results that proposed algorithm preserves better spatial and spectral information and better visual quality compared to earlier reported methods.

The phase excitation pulse of the Switched Reluctance Motor (SRM) must be synchronized with the angular rotor position to ensure the continuous torque and rotation of the rotor and also to obtain the optimum performance of the SRM drive. In this paper Artificial Neural Network (ANN) based sensorless rotor position estimation technique is presented to fulfill the requirement of the position feedback for the SRM. MATLAB simulink environment is used to design a neural network and to simulate the proposed sensorless method which shows satisfactory result. An idea is presented to reduce the number of neuron for mapping the magnetic characteristics of the neural network which can reduce the complexity and computation burden without much affecting the performance of the SRM. Region of interest of the magnetic characteristics is described & discussed first time in this paper which helps to analyse a region of the magnetic characteristics where the significance of accuracy of the rotor position estimation is more compared to exterior region.

This paper investigates the effectiveness of Model Predictive Controller and its ability to damp out the low frequency oscillations and improve the small signal stability of single machine infinite bus system. The damping functions of the UPFC with various alternative control signals are investigated on the basis of linearized Heffron Phillips model of SMIB equipped with UPFC. The performance of model predictive controller has been compared to that of a controller based on phase compensation technique and is found to be superior as it uses the optimized control inputs to bring stability to the plant. The performance effectiveness of various control signals is evaluated and the best way of controlling the UPFC is proposed.

Image fusion is important algorithm in many remote sensing applications like visualization, identification of the boundary of the object, object segmentation, object analysis. Most widely used IHS method preserves the spatial information but distorts the spectral information during fusion process. IHS method is also limited to the three bands. In this paper, the MS based difference with respect to its mean image is used to reconstruct the fused image. In this the mean of the MS band is replaced by the mean of the PAN image. In this way both spatial and spectral information are taken into account in the process of image fusion. We have considered actual dataset of IKONOS four band image for our experiment. It has been observed from the simulation results that the proposed algorithm preserves both spatial and spectral information better than compared standard algorithm and it also significantly improves the universal quality index which measures the visual quality of fused image.

In the present era of space application, use of FPGA has been increase dramatically and because of that the developed SEU Monitor System can be used to inject the error manually into the FPGA and after that detection and correction can be confirmed. Also, injected error can be used to verify the effectiveness of the mitigation technique added into the design. We describe the operation and architecture of the proposed logic design as well as its implementation in Xilinx virtex-5 FPGA.

In this paper Electromechanical Simulator for Weapon System Launching Platform is presented. A weapon system launching platform requires freedom of movement in seven axes. It has to move in four axes for levelling, vertical and horizontal axes for articulating the launching platform and up and down sliding of the launching structure or weapon article. All these movements are simulated using Electromechanical Servo Drive in a Simulator for training and experimental study purposes of the personnel involved in development and handling of weapons system launching platform. Electromechanical servo drive requires position feedback, velocity feedback and current feedback to move a system in desired direction in specified time following predefined motion profile. In this paper, Launcher Simulator with Electromechanical servo drive system is discussed. This Simulator is designed and developed for simulating the real scenario working requirements of a weapon system launching platform.

Task level robot systems have long been a goal of robotics research. This paper discusses a project to design and develop a humanoid robotic arm which could reach a particular position defined by the specific set of co-ordinates, pick up the object and place it at the target location defined by another set of co-ordinates, in a well defined hemi-spherical 3D space. The developed prototype provides total 5 Degrees of freedom within the robotic arm. Micro servo motors are used as principle actuators. The arm is controlled by a computer thorough a simple user interface application developed in basic Rapid Application Development (RAD) software. The object position and destination co-ordinates are entered in the user-interface application and the object is grabbed using the gripper. A manual over-ride control is also provided in which the movement of the robotic arm can be controlled using a manual control panel.

This paper presents the investigations on two patch type slot loaded Frequency Selective Surface (FSS). In the first design, patches of the FSS are designed with 0° rotations to one another while in the second design; adjacent patches are at 90° rotations to one another. In the latter design due to symmetrical nature of the design; the FSS becomes totally polarization independent for 90° rotations about any vertical axis, perpendicular to the FSS plane and passing through its centre and the design also reveals reduced patch size of the FSS with multiband characteristics. The proposed designs have been investigated theoretically using ANSOFT® software. In comparison to the conventional square patch Frequency Selective Surface (FSS) without slot, this slotted square patch FSS with second design can provide reduction in resonant frequency resulting in size reduction up to 94%. The second structure acts like a band reject filter with three bands having resonant frequencies of 5.93 GHz, 9.25 GHz and 13.8 GHz.
