Advances in Computational Research , 2012,
Abstract: Mango fruit is one of the most popular, nutritionally rich fruit with unique flavor, fragrance, taste, and heath promoting qualities making it a common ingredient in new functional fruits often called “super fruits”. The Edge detection process detects outlines of mangos, mango quality evaluation and mango types, counting mangos, check Inflorescence quality. An edge is the boundary between mangos and the background. Simulink is a simulation modeling and design tool and GUI based diagram environment. The Simulink based customizable framework is designed for rapid simulation, implementation, and verification of video processing systems. In this work the comparative analysis of various mangos video edge detection methods is like Sobel, Prewitt, and Canny is presented.

Abstract: Accurate estimates of the magnitude of the floods that affected southern Africa in February 2000 are difficult to obtain since floodwaters damaged the majority of gauging stations on affected rivers. It is possible to estimate the peak discharge experienced in the Letaba River in the Kruger National Park by simulating the hydraulic and geometric characteristics of the peak flow and relating these to the roughness of the channel. Peak water surface slope data were determined from debris and mudline measurements at breaks in channel type. These data are combined with published high-flow channel resistance coefficients for different channel types to generate peak flow estimates for eleven different cross-sections, located between tributaries to allow for sub-catchment contributions to be estimated. In February 2000 flow peaked at approximately 4000 nWs near to Black Heron Dam (in the west of the park), and increased to approximately POOOm^s just upstream of the confluence with the Olifants River. Comparison with gauge records indicates that the February 2000 peak was higher than any flow during the proceeding four decades.

The February 2000 floods on the Sabie River, South Africa: an examination of their magnitude and frequency
G.L. Heritage,B.P. Moon,G.P. Jewitt,A.R.G. Large
Koedoe : African Protected Area Conservation and Science , 2001, DOI: 10.4102/koedoe.v44i1.184
Abstract: The floods that affected much of Southern Africa in February 2000 have been reported as the largest in living memory by many observers. However, the force of the floods damaged the majority of the gauging stations located on the affected rivers, many of which were not constructed to measure flows of such a magnitude. This paper presents an estimation of the peak flood discharge on 6 February 2000 for the bedrock influenced Sabie River in the Kruger National Park, by simulating the hydraulic and geometric characteristics of the peak flow and relating these to the roughness character of the channel. Peak water surface slope data in the form of strandline measurements at channel type breaks along the river were collected for six sites along the Sabie River within the Kruger National Park. Flood conditions within each channel type were considered to approximate to uniform flow. The cross-sections are located between major tributary inputs allowing for approximate sub-catchment flow contributions to be estimated. The results indicate that the flow peaked at around 3000 mVs at the Kruger Gate entrance to the Kruger National Park, increasing to approximately 5500mVs at Skukuza and 7000 mVs at Lower Sabie close to the Mozambique border following inputs from the Sand River sub-catchment. These estimates compare well with the simulated rainfall runoff total of 4300 mVs at Skukuza, however, precipitation inputs over the lowveld appear to indicate that the discharge only rises to 4950 mmVs at Lower Sabie. A flood flow of this magnitude has never been experienced based on the simulated flow data generated by the ACRU hydrological model calibrated against measured flows therefore suggesting a return period in excess of the 60 years of record.
Coast Down Time Analysis to Analyze the Effect of Misalignment in Rotating Machinery
G.R. Rameshkumar,B.V.A. Rao,K.P. Ramachandran
International Journal of Engineering and Advanced Technology , 2012,
Abstract: Shaft misalignment in rotating machinery is one of the major industrial concerns. When the power supply to any rotating system is cut-off, the system begins to lose the momentum gained during sustained operation and finally comes to rest. The exact time period between the power cut-off time and the time at which the rotor stops is called Coast Down Time. In this paper an experimental study was conducted to investigate the effect of angular misalignment in forward curved centrifugal blower test setup. Tests were conducted for various level of angular misalignment at different shaft cut-off speeds. The results show that the coast down time decreases with increase in level of angular misalignment. At higher speed and at higher level of angular misalignment, the impact on percentage reduction in CDT is very high and there is a specific correlation between the percentage reduction, cut-off speeds and the level of introduced angular misalignment. The vibration signatures acquired at different cut-off speeds and at the various level of angular misalignment conditions. The 2X and 3X vibration amplitude components are predominant frequencies and increase as the angular misalignment and shaft rotational speed increases, thereby establishing the fact that the CDT analysis can be used as one of the diagnostic condition monitoring parameter for rotating machinery.

Indian Phytopathology , 2011,
Abstract: Present study was conducted for six years during 2001 to 2006 to find out frequency of distribution leaf rust pathotypes prevailing in central and peninsular India and based on this data status of efficacy of Lr genes against the pathogen have been worked out. In Central and Peninsular India, Leaf rust (Puccinia triticina Eriks) pathotype 77-5 (121R63-1) was widely prevalent on wheat from 2001 to 2006 and pathotype,77-7(121R127) and 77-8 (253R31) have emerged out to be important pathotypes recently. Lr 24 gene is effective against all the pathotypes in this region followed by Lr9 and Lr19 genes. The other promising resistant genes include Lr23, Lr 20 and Lr15. It can be concluded that incorporation of Lr genes mentioned above in wheat breeding programme will help in evaluation of varieties having desirable resistance to this pathogen in central and peninsular India.

International Journal of Innovative Technology and Exploring Engineering , 2012,
Abstract: Rotor unbalance is the most common cause of vibration in any rotating machinery. The Coast Down Time is used as a condition monitoring parameter to monitor the rotating machinery. The CDT is the total time taken by the system to dissipate the momentum acquired during sustained operation, which is an indicator of mechanical faults. Experiments were carried out on Forward Curved Centrifugal Blower to record the CDTs at selected blower shaft cut-off speeds of 1000 rpm, 1500 rpm, 2000 rpm and 2500 rpm respectively for various unbalance conditions. These experimental CDT data were used to train the neural network. The paper also discusses the successful incorporation of radial basis function neural network (RBF-NN) for the CDTs prediction for unbalance fault conditions. The results showed that the RBFNN predicted CDT values are very close to the experimental CDT values.

Revista Brasileira de Farmacognosia , 2003, DOI: 10.1590/S0102-695X2003000300009
Abstract: extracts of 13 brazilian medicinal plants were screened for their antimicrobial activity against bacteria and yeast. of these, 10 plant extracts showed varied levels of antibacterial activity. five of the plant extracts presented compounds with rf values similar to the antibacterial compounds visible on bioautogram. of these, three plants belong to the compositae family. this may mean that the same compounds are responsible for the antibacterial activity in these plants. anticandidal activity was detected in 9 plant extracts. the results might explain the ethnobotanical use of the studied species for the treatment of various infectious diseases.

Abstract: Survey was conducted during the rainy season from 2002 to 2005 from Sangli, Kolhapur, and Satara districts of Maharashtra state and border areas of Karnataka to know the situation of soybean rust. Results indicated that disease is widely prevalent in these areas. It appeared from second week of July during 2004 and from August onwards during other years. Incidence of rust varied from 0-100 percent during individual years. First infection was noticed at Dattawad, Bubnal and Shirdwad villages of Shirol talukas of Kolhapur districts. This area adjoining to Krishna river belt seems favourable for early infection from where disease spread to Sangli, Satara districts and adjoining area.
