Despite the various infectious disease, mycobacterial disease continue to be important public health problems all over the world. Mycobacteria have long been recognized as important human gathogen. The WHO has identified India as a major hot-spot region for Mycobacterium tuberculosis infection (Siddiqi et al., 2002). In 1997, there were estimated 4.8 million prevalent cases of TB and of these 2.2 million were smear positive.

The method applies failure and repair rate signals to learn the hidden relationship presented into the input pattern. Statistics of availability of several years is considered and collected from the management of concern plant. This data is considered to train and calidate the radial basis neural network (RBNN). Subsequently validated RBNN is used to estimate the availability of concern plant. The main objective of using neural network approach is that it’s not require assumption, nor explicit coding of the problem and also not require the complete knowledge of interdependencies, only requirement is raw data of system functioning.

It is utilized to recognize and arrange the sentiments communicated in writings. The web-based social networking sites like twitter draws in a huge number of clients that are online for imparting their insights in the form of tweets or comments. The tweets can be then classified into positive, negative, or neutral. In the proposed work, logistic regression classification is used as a classifier and unigram as a feature vector. For accuracy, k fold cross validation data mining technique is used. For choosing precise training sample, tweet subjectivity is utilized. The idea of Effective Word Score heuristic is likewise presented to find the polarity score of words that are frequently used. This additional heuristic can speed up the classification process of sentiments with standard machine learning approaches.

To arrive at a specification, our goal, in this paper, is to establish the functional requirements of a DRPI, based on service requirements that we have previously defined. Our goal is to arrive at a specification that can be applied throughout the aircraft design process, therefore the service requirements are based on an analysis of the high-level design activities, in terms of the design data and design process management needs and the information types and communication frequencies between activities. In this paper we perform an interpretation of the required services in order to form the basis for the functional requiremcnts of a DRPI.

Research paper thumbnail of Fundamental Bound on the Reliability of Quantum Information Transmission

Physical Review Letters, 2013

For classical information sent over classical or quantum channels, one could, under certain conditions, make a stronger statement that the reliability of the transmission shall decay exponentially to zero with the number of channel uses and the proof of this statement typically relies on a certain fundamental bound on the reliability of the transmission. Such a statement or the bound has never been given for sending quantum information. We give this bound and then use it to give the first example where the reliability of sending quantum information at rates above the capacity decays exponentially to zero. We also show that our framework can be used for proving generalized bounds on the reliability.

Such codes have simple single-symbol decoders. The code rate can be made higher by constructing quasi-orthogonal codes, which trade a small loss of performance for full rate coding. Typically, quasi-orthogonal codes perform the best when joint maximum likelihood (ML) decoding

The optimal rotation of the symbols increases the minimum distance of the corresponding space-time codewords, leading to substantially improved performance.

Research paper thumbnail of Reduced-complexity ML decoding of rate 6/8 and rate 1 linear complex space-time codes for up to eight transmit antennas with phase feedback

The performance of the code is the same as that of an ideal code, for which the sufficient statistic of the channel is its Frobenius norm. For rate 1 codes for up to eight antennas, a two-phase feedback enables a symbol to see the interference from only one symbol instead of three, thereby reducing the complexity of ML decoding. Quantization of the feedback is also considered.

Its goal is to analyze soilsection images, extract features related to their micromorphology, and relate the visual features to various degrees of soil fertility inferred from biochemical characteristics of the soil. The image methodologies used range from low-level image processing tasks, such as nonlinear enhancement, multiscale analysis, geometric feature detection, and size distributions, to object-oriented analysis, such as segmentation, region texture, and shape analysis.

Research paper thumbnail of Molecular characterization and pathogenicity of swine influenza H9N2 subtype virus A/swine/HeBei/012/2008/(H9N2)

Pigs are susceptible to both human and avian influenza viruses and have been proposed to be intermediate hosts for the generation of pandemic influenza viruses through reassortment or adaptation to the mammalian host. To further understand the genetic characteristics and evolution, we investigated the source and molecular characteristics of the H9N2 subtype swine influenza virus (SIV), and observed its pathogenicity in BALB/c mice. The BALB/c mice were inoculated intranasally with 100 median mouse infectious dose of A/swine/HeBei/012/2008/(H9N2) viruses to observe the pathogenicity. The HA, NP, NA and M gene were cloned, sequenced and phylogenetically analyzed with related sequences available in GenBank. The infected mice presented with inactivity, weight loss and laboured respiration, while the pathological changes were characterized by diffuse alveolar damage in the lung. The nucleotide and deduced amino acid sequence of HA, NP, NA and M gene was similar with that of A/chicken/Hebei/4/2008(H9N2). The HA protein contained 6 glycosylation sites and the motif of HA cleavage site was PARSSR GLF, which is characteristic of low pathogenic IV. In the HA, NP, M and NA gene phylogenetic trees, the isolate clustered with A/chicken/Hebei/4/2008(H9N2). The isolate possibly came from A/chicken/Hebei/4/2008(H9N2) and was partially varied during its cross-species spread.

Research paper thumbnail of Overhead Analysis of AODV, TORA and AOMDV in MANET Using Various Energy Models

The three different energy models considered are (a) Bansal Energy Model (b) Vaddina Energy Model and (c) Chandrakasan Energy Model. We apply these energy models to AODV, TORA and AOMDV routing protocols to determine the energy overhead among these three routing protocols by varying the transmission range. Our aim is to analyze how these routing protocols behave under different energy models. In the analysis of energy overhead the underlying mobility model also plays a very important role. We have selected the RWP-SS mobility model. In literature many research papers skip the initial simulation time while simulating the routing protocols but this particular mobility model enables us to calculate the energy overhead from the start of the simulation.
