There are reports of taste sensor fabrication by incorporating lipids in PVC matrix. We have taken an attempt to prepare taste sensor material by using functionalized polymer. Polyvinyl alcohol (PVA) and polyacrylic acid (PAA) have been modified to fabricate the sensor material. The research work covers polymer membrane preparation, morphology study, and structural characterization of membrane and study of the taste sensing characteristics. The membrane was prepared by cross-linking polyvinyl alcohol and polyacrylic acid in aqueous-organic medium by using hexadecyltrimethylammonium chloride (HDTC) with proper heat treatment. The cross-linked PVA-PAA was phosphorylated with POCl 3 . PVA-PAA membranes of suitable thickness were thus prepared with good threshold sensing value and less swelling in water. FTIR spectroscopic analysis, XRD analysis and optical microscopy were done to get an idea about the structure and morphology of the polymer membrane. Sensor device prepared with this membrane has shown distinct response patterns for different taste substances in terms of membrane potential. The sensor characteristics like temporal stability, response stability, response to different taste substances, and reproducibility of sensing performance were studied. Membranes also showed characteristic response patterns for organic acids like acetic acid, citric acid, formic acid, etc., mineral acids like HCl, H 2 SO 4 and HNO 3 , etc., salt, bitter substance, sweet substance, umami substance and different grades of tea. Sensor device prepared with this membrane has excellent shelf life.

Selective Harmonic Eliminated Pulse Width Modulation (SHEPWM) techniques necessitate the solution of non-linear transcendental equations for achieving optimal PWM strategy. Online solution of these equations is very difficult and the conventional method is to store the offline prepared optimal switching angles in memory, which are to be recalled for online generation of PWM waveforms. The need to achieve continuous voltage and frequency control, especially for AC machines, has imposed large memory requirements and computation time for PWM systems. This paper proposes an effective online method to arrive optimal PWM switching angles based on Curve Fitting Technique (CFT) for three phase inverters. Polynomial functions for optimal switching angles are generated using CFT in MATLAB. The correctness and harmonic performance of the proposed method is verified by comparing the results with the Newton-Raphson (N-R) iterative method.

It was found that the non-perturbative corrections calculated using Pythia with the Perugia 2011 tune did not include the effect of the underlying event. The affected correction factors were recomputed using the Pythia 6.427 generator. These corrections are applied as baseline to the NLO pQCD calculations and thus the central values of the theoretical predictions have changed by a few percent with the new corrections. This has a minor impact on the agreement between the data and the theoretical predictions. Figures 2 and 6 to 13, and all the tables have been updated with the new values. A few sentences in the discussion in sections 5.2 and 9 were altered or removed.

In this paper we describe a prototype model named Intelligent Intrusion Detection System (In2DS) for remote surveillance and monitoring, which further enhances the traditional video surveillance systems. Our approach follows the principle of utilizing Wireless Sensor Networks (WSN) thereby redistributing the work of traditional surveillance systems. We prove that the blend of WSN and video monitoring systems shall effectively improve the classification and characterization of the object of interest. The paper presents a detailed system implementation and operational states carried out in the developed model as a part of the project.

Classification of rice is carried out by human experts in the industry and apart from other attributes like grain size, elongation ratio, aroma plays a significant role in the classification process. On the basis of aroma, the rice samples are manually categorized as strongly aromatic, moderately aromatic, slightly aromatic and non aromatic. Instrumental evaluation of aroma of rice is much needed in the industry and in this paper, we describe an electronic nose instrument, that has been developed for aroma characterization of rice. Artificial neural network is used for the pattern classification on data obtained from the sensor array of the electronic nose. With unknown rice samples, aroma based classification accuracy has been observed to be more than 80%. © 2011 IEEE.

This paper presents a method of estimation of facial expression intensity from a sequence of binary facial images obtained from video. The binarization has been done using a neuro-visual model of figure ground segregation. The Local Binary Pattern (LBP) is taken as characteristic feature of a face with expression. This pattern gets evolved in the temporal domain over the sequence. The dynamics of the pattern, starting from a neutral face, is characterised by Hausdorff distance. Back Propagation (BP) Neural Networks are trained to estimate the expression intensity level of the basic expressions.

Computerized human face recognition is a complex task of deformable pattern recognition. The principal source of complexities lies in the significant inter-class overlapping of faces due to the variations caused by different poses, illuminations, and expressions (PIE). The popularly used computerized face recognition algorithms like PCA, EBGM etc. are fairly reliable to determine facial attributes from an image. But, in most of the cases the features are extracted in terms of gray textures. When the database size is tuned to millions, then huge processing time is required, as each of the pixel must be represented using at least eight bits. In the present paper, our objective is to minimize the processing time by reducing the number of bits to represent each pixel. This we have done by combining two methods. The first one is a neuro-visually inspired method of figure-ground segregation (NFGS) which can convert the entire face image into a binary 2D array, efficiently. The second one is the scale invariant feature transform (SIFT) which extracts the scale invariant and rotation invariant features from the binarized face image and thereafter matches the features. The proposed algorithm is found successful in actually enhancing the performance of face matching. Psycho-visual experiments also corroborate the fact.

The Pessimistic commit protocol specifies set of rules which guarantee that every single transaction in a mobile database environment is executed to its completion or none of its operations are performed. To show the effectiveness of pessimistic commit protocols, a generic simulator is designed and implemented to demonstrate how the transactions are committed and how the data consistency is maintained when the transactions are executed concurrently. Further the constraints imposed by mobile database environments like mobility, blocking of data items etc. are effectively handled. The simulator is tested for efficiency for all timeout based strategies proposed in the literature. © 2010 Springer-Verlag Berlin Heidelberg.
