Classification of normal and various graded cancer tissues requires a robust distance measure to account for the problems of background noise, source separation and outliers which are inherent to elastic scattering spectroscopy data. It must also have the interpretations for the variation in correlations existing in refractive index fluctuations due to inhomogeneity between healthy and different grades of cancerous tissues. In this contribution, we propose the amalgamation of the L1 distance family and Mahalanobis distance metrics to account for problems mentioned above. The proposed metric for the special case of Manhattan and Chebyshev with Mahalanobis metric has been shown. The efficacy of the proposed distance measure based classification to discriminate the normal and graded cancer tissues with K-NN classifier have been done. Classification accuracy of 93.75%, with sensitivity of 100%, and specificity of 91.94%, validates the suitability of the proposed methodology for pre-cancer detection.

Directional sound is used for many applications like in-store displays that require to be active only when one walks past to it, hospital televisions that particularly focus sound to specific patient, for police announcements, for the announcements in galleries, museums, and exhibitions, analysis of layered structures etc. Nowadays, highly directional loudspeakers with beam-widths as narrow as 5 degrees are available. The quality of both the male and the female speech signal produced by the directional loudspeaker as a function of source degradation is analyzed using P.862 at different signal power to noise power ratio values. The speech quality produced by the directional loudspeaker is also compared with the speech quality produced by a normal omni-directional loudspeaker based on the mean opinion score. It is observed that the normal omni-directional loudspeaker produces better quality speech compared to the directional loudspeaker.

Overlapping of cervical cancerous cells and presence of debris, mucus and blood play a major issue in accurate segmentation of cells. Manual screening of overlapped cells in Pap smear slides is prone to error due to the complexity, high variation in shape and size and poor contrast of images. The automated system must be able to detect the nucleus and cytoplasm of clumped cells accurately as merging of cells is a characteristic of high stages of cervical cancer. In this paper, we propose a novel method to accurately segment the overlapping cells by dividing the whole image into many small non-overlapping pixel blocks, then extracting the texture features from Gray level co-occurrence matrix GLCM. The overlapped parts have a noticeable change in certain features which help us in selecting the area of interest which is marked explicitly and further the contours are marked using Independent level set method, accurately segmenting the cell nucleus and cytoplasm.

A novel technique is proposed for categorizing sports events in videos by tracking the positional and angular displacements of the centroid of the moving object in between successive frames. The various sporting events contained in videos are distinguished either by the speed of motion, for instance walking, jogging and running, or by the trajectory made by the human body while in motion, for instance diving, kicking, bending, lifting weights, jumping and playing golf. The speed of motion is measured by the randomness in the position vector magnitude, and the time-series of angular displacements represents the trajectory. Our method employs minimal training with only a single training video used as the reference for each sporting activity. Experimentation on the KTH, UCF and Weizmann datasets and comparisons with existing methods validate the efficiency of our approach which is simple and easy to implement. The accuracies are further improved by using the Hidden Markov Model to generate posterior state probability sequences from our extracted features which is then used for classification.

In this work, multiple time-scale estimates of auditory features have been introduced to capture the effect of short time-transients additive noise present over some specific active regions in a speech utterance and these multiple time-scale auditory features have been used for non-intrusive speech quality measurement. The use of single time-scale auditory features is not accurate in capturing the time localized information of short-time transient distortions and their distinction from plosive sounds of speech. Hence, the importance of estimating auditory features at multiple time-scales that is relevant for objective non-intrusive speech quality estimation. The different active speech segments obtained from voice activity detection (VAD) algorithm of speech utterance are combined across the segments in increasing number of active speech segments till all the segments of complete speech utterance are accounted for. The Lyon's auditory features of the combination of active speech segments are computed on frame by frame basis. The mean, variance, skewness and kurtosis over the frames of the auditory features are computed and concatenated to obtain multiple time-scale estimates of auditory features for the different combination active speech segments. These multiple time-scale auditory features are probabilistically modeled using Gaussian Mixture Model (GMM) to map into mean opinion score (MOS) value for each combination of active speech segments. The overall objective MOS of the degraded speech is obtained by taking average of MOS values of the combination of active speech segments. A detailed result comparison has been done with the ITU-T Recommendation P.563 for telephone band speech.

Biological processes embody molecular regulatory mechanisms equivalent to the notion of signaling used in engineering. Using signaling as a paradigm, we constructed human cancer signaling network embodying empirically reported molecular mechanisms underlying cancer. We further identified driver nodes and classified them based on their role in structural controllability of this network. We hypothesize that nodes that are critical for achieving centralized control are therapeutically important. We observed that anti-cancer drugs primarily act through such genes that serve as their targets. Despite significant differences between networked systems in engineering, for which structural controllability has been traditionally designed, we present a study that reveals its utility for analysis of disease networks with therapeutic implications.

The performance of an optical wireless communication (OWC) system subjected to atmospheric turbulence induced fading can be significantly improved by using spatial diversity reception. Diversity reception also suffers from correlation among diversity branches due to insufficient spacing between multiple photodetectors at the receiver. In this paper, average channel capacity of OWC system employing maximal ratio combing (MRC) and equal gain combining (EGC) diversity reception with correlated diversity branches is evaluated using a simple expression based on point estimate. A weak atmospheric turbulence condition known to be modeled by log-normal distribution is considered. In addition, the impact of correlation is also investigated considering identical as well as non-identical turbulence induced fading among diversity branches. This analysis reveals that the channel capacity decreases with the increase in correlation coefficient and impact of fading correlation is higher in case of identically distributed diversity branches as compared to non-identically distributed branches. Validity of the analysis is demonstrated with the results obtained using Monte-carlo simulation.

In most digital signal processing (DSP) applications like image processing and speech processing, human beings can collect useful information from slightly inexact outputs. This type of computing is referred as inexact computing which does not provide exactly correct numerical outputs. Inexact computing uses approximate circuits rather than exact circuits to perform the computations. Approximate circuits consume less power, require less number of transistors and have less propagation delay than exact circuits. Approximate adder is the building block of inexact computing for DSP applications. This paper presents a design of a 32-Bit approximate adder which has low power consumption and requires less number of transistors than existing approximate adders. The proposed approximate adder has power savings of 8% for 32-Bit as compared to existing designs. The proposed adder has significant reduction in area (number of transistors) than existing designs. All the circuits have been simulated in Cadence Virtuoso tool using 45-nm technology.
