Video denoising without motion estimation using K-means clustering


















C Ramya & S Subha Rani

This study presents a novel dictionary pruning algorithm that found dictionaries of optimized size for a given dataset, without compromising its approximation accuracy and performance. It is achieved by applying KSVD (K-means singular value decomposition) algorithm to patches of dictionary. Proposed method optimized dictionary selection, and with KSVD yielded better video denoising than KSVD with fixed dictionary.

Quaternion wavelets based rotation, scale and translation invariant texture classification and retrieval
















B Sathyabama, P Chitra, V Gayathri Devi,
S Raju & V Abhaikumar

This study addresses problem of classifying rotated, scaled and translated texture image using two stage log polar quaternion wavelet energy signatures. Sum of squared distance is employed to classify a set of 38 distinct natural textures selected from Brodatz album and 48 from Outex texture database. Based on different testing data sets for images with different orientations scales and translation, proposed classification scheme using QWT outperforms other approaches, giving a good classification accuracy and retrieval efficiency (grey scale, > 85% and color textures, > 83%).

Limited area route discovery for mobile
ad hoc networks



Anuradha Banerjee & Paramartha Dutta

This study proposes a limited area route discovery scheme that greatly reduces number of route-requests flooded in network and delay in discovering a suitable route to destination, irrespective of underlying protocol. Also, average node lifetime increases along with number of data packets successfully delivered to destination.

Automatic isolated digit recognition system: an approach using HMM


















Kritika Nimje & Madhu Shandilya

This study presents design and development of an automatic isolated digit recognition system (AIDRS) using Hidden Markov Model (HMM). Basic model of the system is able to recognize spoken digit utterances in English. Implementation part has been done by using Hidden Markov Toolkit (HTK). System is found successful and can identify spoken digit at 89.2% recognition rate, which is well acceptable rate of accuracy for speech recognition.

Deposition of TiAlSiN hard film by cathodic arc plasma evaporation using a single target combined with a shield filter



















Pham Van Vinh & Tran Vu Diem Ngoc

Films of TiAlSiN were deposited on AISI H13 tool steel substrate by a cathodic arc-plasma deposition system using a single TiAlSi alloy as target. Presence of TiN crystal phase was found on films, but no XRD peaks related to Al and Si were found. Hardness, morphology and adhesion of films changed with different deposition parameters. Maximum hardness (36.29GPa) of films was found on sample deposited at 300C with 3x10‑3 Torr and cathode arc current of 45 A.

Determination of optimal cutting conditions in finish turning of austempered ductile iron using Taguchi design method




A Kacal & M Gulesin

This study presents optimization of process parameters using Taguchi design method in finish turning of austempered ductile iron. An orthogonal array of L18 was used; ANOVA was performed to identify significant factors affecting surface roughness (Ra) and primary cutting force (Fc). Optimum processes parameter combination was acquired by using analysis of signal-to-noise (S/N) ratio. For Ra and Fc values, prediction error was found to be within the confidence limit at 95% confidence level.

Multi-response optimization of carbidic austempered ductile iron production parameters using Taguchi technique





P Dhanapal & S S Mohamed Nazirudeen

This study presents optimal production parameters in the manufacture of Carbidic Austempered Ductile Iron [CADI] through melting route using Taguchi technique. To analyze effect of production parameters on mechanical properties, signal-to-noise (S/N) ratio was calculated based on design of experiments and analysis of variance (ANOVA) used to find the amount of contribution of factors on mechanical properties and their significance. Analytical results of Taguchi method were found identical with experimental values.

Anti-inflammatory activity of Jatropha gossypifolia L. leaves in albino mice and Wistar rat



Rani Bhagat, S D Ambavade, A V Misar &
D K Kulkarni

Methanolic extract of Jatropha gossypifolia L. leaves showed systemic and significant anti-inflammatory activity in acute carrageenan-induced rat paw edema and chronic cotton pellet induced granuloma formation after oral treatment for 7 days in Wistar rats. Anti-inflammatory activity might be due to effects on several mediators and arachidonic granular tissue formation and leukocyte migration from vessels.

Effects of various agro-wastes on xylanase and b-xylosidase production of anaerobic ruminal fungi






This study presents effects of agro-wastes (wheat straw, barley straw, oat straw and corncobs) on production of extracellular xylanase and b-xylosidase of anaerobic fungal strains (10), isolated from fecal samples of cattle, goat and sheep. Orpinomyces sp. P4 exhibited remarkable xylanase activity (3.67 - 5.01 U ml-1) on all sustrates. Cyllamyces sp. P7 showed least xylanase activity, however produced more xylanase in corncob containing medium (3.18 U ml-1) as compared to other substrates. Secretion of b-xylosidase was comparatively lower in polycentric isolates as compared to monocentric isolates. Neocallimastix sp. M2 produced maximum b-xylosidase activity (1.87 U ml-1) in xylan containing culture.

Design of solar insolation power logging system with ADC error testing and correction
























K Hariharan, T J Rambabu,
R K M Rajkumar & V Abhaikumar

This study presents a low cost solar insolation meter with accurate measurement of inherent non-linear transfer characteristics of ADC. Measured values were found close to accuracy of highly sophisticated instruments (pyranometer and pyrheliometer), which are costlier for large-scale use, low commercial availability and need for a specialized knowledge for handling. Test results over a long duration under varying seasonal conditions were almost identical to those of a calibrated standard pyranometer.

Evaluation of suitability of oil well drill cuttings for road making




















A K Misra, Renu Mathur, Pankaj Goel & Manoj Kumar Singh

This study presents that oil drill cuttings waste can be a very good costruction material for sub-grade preparation of roads without causing any toxic effects on natural soil/ ground water etc. Use of drill cuttings for sub-grade construction will reduce pavement thickness and thus cost of construction will also be less.
