An Approach for Classification of Dysfluent and Fluent Speech Using K-NN And SVM
P. Mahesha,D. S. Vinod
Computer Science , 2013, DOI: 10.5121/ijcsea.2012.2603
Abstract: This paper presents a new approach for classification of dysfluent and fluent speech using Mel-Frequency Cepstral Coefficient (MFCC). The speech is fluent when person's speech flows easily and smoothly. Sounds combine into syllable, syllables mix together into words and words link into sentences with little effort. When someone's speech is dysfluent, it is irregular and does not flow effortlessly. Therefore, a dysfluency is a break in the smooth, meaningful flow of speech. Stuttering is one such disorder in which the fluent flow of speech is disrupted by occurrences of dysfluencies such as repetitions, prolongations, interjections and so on. In this work we have considered three types of dysfluencies such as repetition, prolongation and interjection to characterize dysfluent speech. After obtaining dysfluent and fluent speech, the speech signals are analyzed in order to extract MFCC features. The k-Nearest Neighbor (k-NN) and Support Vector Machine (SVM) classifiers are used to classify the speech as dysfluent and fluent speech. The 80% of the data is used for training and 20% for testing. The average accuracy of 86.67% and 93.34% is obtained for dysfluent and fluent speech respectively.
Carbon Nanotube Reinforced Aluminium Matrix Composites – A Review
SHADAKSHARI R,DR.MAHESHA K,NIRANJAN H B
International Journal of Innovative Research in Science, Engineering and Technology , 2013,
Abstract: The present paper illustrates mixing procedures for Al-CNTs powder preparation alongside depiction of the CNTs dispersion results from the different mixing techniques. XRD analysis showed that the mean grain size of powders milled for 6 h was found to be 48.4 nm and for extrudates of CNT-Al, it is 56.6 nm. Based on the geometry and physical properties of multiwalled nanotubes, three strengthening mechanisms were considered for CNT/Al composite system. It was evident from the testing that as the content of nanotubes in the matrix increased, the micro-hardness measured on the Vickers scale also increased. The investigation of the damping behaviour of 2024Al-CNT composite showed that the damping capacity of the composite with a frequency of 0.5 Hz reaches 975 x 10-3, and the storage modulus is 82.3 GPa when the temperature is 400 C, which shows that CNTs are a promising reinforcement for metal matrix composites to obtain high damping capabilities at an elevated temperature without sacrificing the mechanical strength and stiffness of a metal matrix.

Golden Research Thoughts , 2012, DOI: 10.9780/22315063
Abstract: Geography touches every aspect of our lives. At its simplest, geography is concerned with where something is at, why it's there, and how it relates to things around it. Geography influences where we live, affects our economic prosperity, has dictated the outcome of significant historical events, and shapes our local, regional, and global relationships with each other. Therefore, it is taught at school level with a view to strengthen students' understanding of Geographic aspects and their roles in the development.Geography as a core school subject is introduced in Karnataka at 8th standard. Since, its inception a duration of 30 years is passed over. This paper is focused on the Geography teaching with following objectives:
Child Sex Ratio In Karnataka- A Spatio- Temporal Analysis
D. Mahesha,B.N. Shivalingappa
Indian Streams Research Journal , 2012,
Abstract: Sex Ratio is a sensitive indicator that displays in a way the status of women.Concerted efforts are needed to create equal regard and affection for the girl child. Thesex ratio among children (0 to 6 years) is showing a continuous decline in northern stateslike Punjab, Haryana, Himachal Pradesh, Delhi and Gujarat. Many families decide toremove the female foetus in a quest for sons. Unfortunately this happens in the moreeducated and affluent localities. The motivation is primarily to protect property, familybusiness and to avoid giving dowry. If there has to be a change in mindset, leaders insociety have to show the way. Otherwise the population will become skewed leading to ahost of societal problems like increased crime against women.This paper tries toexamine the regional patterns of sex ratio for children aged 0 to 6 using District leveldata collected by the 2011 census. Great regional disparities in sex ratios among youngchildren were observed. Nearly half of State population now lives in areas where the sexratio of children aged 0 to 6 is below 943 girls per 1000 boys. Declining sex ratios hasalready become a serious social problem. Some explanations are offered for regionalvariations in the sex ratios of young children.
The Effect of Heat treatment on Microstructure, Mechanical properties and Damping behaviour of hybrid composite of A356.0
VINAYAK JANIWARAD,SHADAKSHARI R,M.H. ANNAIAH,DR.MAHESHA K
International Journal of Innovative Research in Science, Engineering and Technology , 2013,
Abstract: In this study, Al-Si-Mg alloys A356.0 were stir cast by liquid metallurgy route with varied percentage of Alumina and Graphite. The composites were T6 treated and tested for microstructure and mechanical properties. Microstructure revealed uniform distribution of reinforcement in the matrix resulting in improved bonding of reinforcement in the matrix which in turn improved mechanical properties and Damping behaviour compared to un-reinforced material. The ceramic reinforced alloys were found to have improvement in Mechanical properties and Damping behaviour which may be attributed to the uniform distribution and bonding of reinforcement in the matrix.

Vector Quantization and MFCC based Classification of Dysfluencies in Stuttered Speech
P. Mahesha
Bonfring International Journal of Man Machine Interface , 2012, DOI: 10.9756/bijmmi.2019
Abstract: Stuttering also known as stammering is a speech disorder that involves disruptions or dysfluencies in speech. The observable signs of dysfluencies include repetitions of syllable or word, prolongations, interjections, silent pauses, broken words, incomplete phrases and revisions. The repetitions, prolongations and interjections are important parameter in assessing the stuttered speech. The objective of the paper is to classify the above mentioned three types of dysfluencies using Mel-Frequency Cepstral Coefficients (MFCC) and Vector Quantization (VQ) framework. For each dysfluency MFCC features are extracted and quantized to a number of centroids using the K-means algorithm. These centroids represent the codebook of dysfluencies. The dysfluencies are classified according to the minimum quantization distance between the centroids of each dysfluency and the MFCC features of testing sample.

Abstract: A retrospective review of all cases reported as medulloblastoma between the period of Jan 2000 to Dec 2006 was carried out on Hematoxylin and eosin (H & E) stained slides. The cases were screened on light microscopy for primitive neuroectodermal component of a medulloblastoma accompanied by areas of "myoid" differentiation, identified on the basis of presence of strap cells (indicating a clear skeletal muscle differentiation) and/or large anaplastic cells with vescicular nuclei and moderate to abundant amount of eosinophilic cytoplasm. All these cases were subjected to a panel of immunohistochemical stains, including Desmin, GFAP, NFP, HMB45, SMA, S100, CK and EMA. Ultrastructral analysis was done on tissue obtained from paraffin blocks in 2 cases.Male predominance (M:F = 5:1) was noted with an incidence of five percent of all cases of medulloblastoma (6 out of 120 cases) over a period of 6 years. Primitive neuroectodermal areas were accompanied with areas of "myoid" differentiation, 5 cases showing strap cells. Two cases with epithelial and cartilaginous differentiation were seen. Three cases showed focal melanocytic differentiation, identified only on HMB45 immunostaining. Four cases showed glial differentiation. Neuronal differentiation again was very focally seen in two cases, of which one was identified only by NFP immunostain. Seventh case is included in the study, however it is not considered to calculate incidence as it occurred beyond the period of 6 years of records search.Medullomyoblastoma is a rare childhood tumor of cerebellum. Majority of cases reveal divergent differentiation, which are identified with the help of panel of immunostains indicating multi-potential nature of primitive neuroectodermal cells.Medullomyoblastoma (MMB) is a rare cerebellar embryonal neoplasm that occurs almost exclusively in children. It has a biphasic histo-morphology, containing myoblastic and primitive neuroectodermal components. MMB arises exclusively in the cerebellum.
