Abstract

A unified strategy is disclosed that builds on successfully engaging the aniline nitrogen of 1,3-amphoteric γ-aminocyclopentenone for a tandem annulation with electron-poor alkynes, solely assisted by the H-bonding network of HFIP. This metal-free mild strategy provides access to medicinally relevant aza-bicyclo-octanes en route to another important scaffold: cyclopenta[b]pyrrole. [ABSTRACT FROM AUTHOR]

15. Multi-Sensor Image Fusion Based on Moment Calculation

Abstract

An image fusion method based on salient features is proposed in this paper. In this work, we have concentrated on salient features of the image for fusion in order to preserve all relevant information contained in the input images and tried to enhance the contrast in fused image and also suppressed noise to a maximum extent. In our system, first we have applied a mask on two input images in order to conserve the high frequency information along with some low frequency information and stifle noise to a maximum extent. Thereafter, for identification of salience features from sources images, a local moment is computed in the neighborhood of a coefficient. Finally, a decision map is generated based on local moment in order to get the fused image. To verify our proposed algorithm, we have tested it on 120 sensor image pairs collected from Manchester University UK database. The experimental results show that the proposed method can provide superior fused image in terms of several quantitative fusion evaluation index., Comment: 5 pages, International Conference

16. Geometric Feature Based Face-Sketch Recognition

Abstract

This paper presents a novel facial sketch image or face-sketch recognition approach based on facial feature extraction. To recognize a face-sketch, we have concentrated on a set of geometric face features like eyes, nose, eyebrows, lips, etc and their length and width ratio because it is difficult to match photos and sketches because they belong to two different modalities. In this system, first the facial features/components from training images are extracted, then ratios of length, width, and area etc. are calculated and those are stored as feature vectors for individual images. After that the mean feature vectors are computed and subtracted from each feature vector for centering of the feature vectors. In the next phase, feature vector for the incoming probe face-sketch is also computed in similar fashion. Here, K-NN classifier is used to recognize probe face-sketch. It is experimentally verified that the proposed method is robust against faces are in a frontal pose, with normal lighting and neutral expression and have no occlusions. The experiment has been conducted with 80 male and female face images from different face databases. It has useful applications for both law enforcement and digital entertainment., Comment: 7 pages, International Conference

17. An Approach: Modality Reduction and Face-Sketch Recognition

Abstract

To recognize face sketch through face photo database is a challenging task for todays researchers. Because face photo images in training set and face sketch images in testing set have different modality. Difference between two face photos of difference person is smaller than the difference between same person in a face photo and face sketched. In this paper, for reduction of the modality between face photo and face sketch we first bring face photo and face sketch images in a new dimension using 2D Discrete Haar wavelet transform with scale 3 followed by a negative approach. After that, extract features from transformed images using Principal Component Analysis (PCA). Thereafter, we use SVM classifier and K-NN classifier for better classification. Our proposed method is experimentally verified by its robustness against faces that are captured in a good lighting condition and in a frontal pose. The experiment has been conducted with 100 male and female face images as training set and 100 male and female face sketch images as testing set collected from CUHK training and testing cropped photos and CUHK training and testing cropped sketches., Comment: 7 pages. arXiv admin note: substantial text overlap with arXiv:1312.1462

Abstract

The reaction repertoire for forming transient aziridinone or azaoxyallyl cations from α-halohydroxamate is conceptually extended to design Kdo-glycosyl donors by installing the hydroxamate moiety at an anomeric centre, which is shown to be highly effective for stereoselective access to β-Kdo glycosides. The pivotal roles of hydroxamate over amide are revealed in control experiments. [ABSTRACT FROM AUTHOR]

39. Robust controller design for rotary inverted pendulum using H∞$H\infty$ and μ$\mu$‐synthesis techniques.

Abstract

An H∞$H\infty$ controller is designed to control a rotary inverted pendulum in its upright equilibrium position. The key contribution of this work is a robust controller architecture design to accommodate for uncertainty in actuator model. Robust stability and performance for a given degree of actuator and measurement uncertainty is achieved using the well established techniques of μ$\mu$‐synthesis and H∞$H\infty$ robust control methods. The design focuses on stabilizing an Inverted Pendulum in an upright position within a tolerable desired angle margin (α$\alpha$). A dynamic plant is designed based on already established theories and published papers. It is observed that the plant is completely observable for the pendulum angle and the motor arm link angle. These two signals are also measurable via encoders and is used as an input for the controller. The output of the controller is voltage actuation which drives the motor to stabilize the pendulum in an upright position (= 0 with +/− 10 deg tolerance). A Robust Stability analysis is done along with Robust Performance, to study the stability and performance margins under modelled uncertainties. As a comparative study, a rudimentary pole placement method is also analyzed. [ABSTRACT FROM AUTHOR]
