Telugu language is considered as fourth most used language in India especially in the regions of Andhra Pradesh, Telangana, Karnataka etc. In international recognized countries also, Telugu is widely growing spoken language. This language comprises of different dependent and independent vowels, consonants and digits. In this aspect, the enhancement of Telugu Handwritten Character Recognition (HCR) has not been propagated. HCR is a neural network technique of converting a documented image to edited text one which can be used for many other applications. This reduces time and effort without starting over from the beginning every time. In this work, a Unicode based Handwritten Character Recognition(U-HCR) is developed for translating the handwritten Telugu characters into English language. With the use of Centre of Gravity (CG) in our model we can easily divide a compound character into individual character with the help of Unicode values. For training this model, we have used both online and offline Telugu character datasets. To extract the features in the scanned image we used convolutional neural network along with Machine Learning classifiers like Random Forest and Support Vector Machine. Stochastic Gradient Descent (SGD), Root Mean Square Propagation (RMS-P) and Adaptative Moment Estimation (ADAM)optimizers are used in this work to enhance the performance of U-HCR and to reduce the loss function value. This loss value reduction can be possible with optimizers by using CNN. In both online and offline datasets, proposed model showed promising results by maintaining the accuracies with 90.28% for SGD, 96.97% for RMS-P and 93.57% for ADAM respectively.

Candida tropicalis was treated with ultraviolet (UV) rays, and the mutants obtained were screened for xylitol production. One of the mutants, the UV1 produced 0.81g of xylitol per gram of xylose. This was further mutated with N-methyl-N’-nitro-N-nitrosoguanidine (MNNG), and the mutants obtained were screened for xylitol production. One of the mutants (CT-OMV5) produced 0.85g/g of xylitol from xylose. Xylitol production improved to 0.87 g/g of xylose with this strain when the production medium was supplemented with urea. The CT-OMV5 mutant strain differs by 12 tests when compared to the wild-type Candida tropicalis strain. The XR activity was higher in mutant CT-OMV5. The distinct difference between the mutant and wild-type strain is the presence of numerous chlamydospores in the mutant. In this investigation, we have demonstrated that mutagenesis was successful in generating a superior xylitol-producing strain, CT-OMV5, and uncovered distinctive biochemical and physiological characteristics of the wild-type and mutant strain, CT-OMV5.

On some parameters Software cost estimation based on development and effort on the project. Every line of code and every method are important to estimate the cost of project. To develop the software project using well defined scientific principles, methods, statements and functions, though there are many costs estimation models are available to estimate the cost of project, but still there is lack of efficient system to predict the cost estimation based on size of project, functionality of project, methods of project. In the existing system cost estimation is done on the basis of lines of code, resource management, in time process. Because of various reasons in the existing system we have identified the drawbacks. In this paper, cost prediction model is defined based on clusters, the number of clusters will form the centroids. Each centroid has a specific number of clusters. Each cluster will be called as rule. In this paper, results will show the prediction of cost estimation is defined.

<P>Single, double and triple trivalent rare-earth (RE3+ = Dy3+, Tm3+, Tm3+/Dy3+ and Tm3+/Dy3+/Eu3+) ions activated Sr2Gd8(SiO4)(6)O-2 (SGSO) phosphors were synthesized by a sol-gel process. X-ray diffraction profiles confirmed their oxyapatite structure after annealing at 1450 degrees C for 12 h. Morphological studies were performed by taking scanning and transmission electron microscopy images, which displayed rod-like shapes. SGSO phosphors exhibited good photoluminescence (PL) properties in the respective regions when doped with Dy3+ and Tm3+ ions. Dy3+ co-activated SGSO: Tm3+ phosphors revealed tunable emissions from cool white light to warm white light towards the yellow region based on the co-activator concentration. However, Eu3+ ions co-doped SGSO: Tm3+/Dy3+ phosphors tuned the emissions towards the red region. The energy transfers from Tm3+ to Dy3+ ions and Tm3+/Dy3+ to Eu3+ ions were established based on the energy level diagram. The cathodoluminescence properties of these phosphors showed excellent emission behavior when the single, double or triple trivalent RE ions were doped into the SGSO host lattice. Unlike the case of the PL, the energy transfer process was observed to take place. The calculated Commission Internationale de l'Eclairage chromaticity coordinates of Tm3+ and Dy3+ individual ion doped SGSO phosphors confirmed the blue and white emissions, while the co-doped samples exhibited tunable emissions.</P>

Genetic analysis of sodium and sodium/potassium (Na/K) ratios in leaf and stem was carried out through diallel analysis involving two tolerant, one moderately tolerant, and two sensitive genotypes as parents. Three-week-old seedlings were subjected to a critical level of salinization (17 decisiemens per meter of electrical conductivity). Leaf and stem sampling (from 5 parents and 20 hybrids arranged in a randomized block design with three replications of 10 each) was done 30 days after salinization when susceptible parents were severely effected. Predominance of non-additive gene action for stem sodium and dominance component for leaf Na/K were noticed while both additive and non-additive components played a significant role for stem Na/K. A single group of genes seems to be operative for these characters. Hybrids produced by crossing the two sensitive parents were tolerant suggesting genetic complementation and involvement of different loci in the two parents for salinity tolerance. The overall dominant nature of tolerance and the additive gene action for these salinity related characters suggested the possibility of breeding pearl millet lines through hybridization and selection to pyramid the favorable genes.

These days, new advances and stages are developing and evolving continually, which suggests a high exertion for creating of complex frameworks, for example, E-learning stage. This circumstance produces distinctive issues identified with compactness, reusability, versatility, incorporation and interoperability. The Object Management Group (OMG) proposes the Model Driven Architecture (MDA), which enhances mobility of uses by permitting the same model to be acknowledged on various stages. Such MDA characterizes a structural engineering focused around platform independent models (PIM) and platform specific models (PSM). The part approach means to outline and create frameworks from pre-assembled segments, predesigned and pretested, to be reused in different applications, which would encourage application's support and development, would advance flexibility and configurability with a specific end goal to create new peculiarities. In this work we introduce LMSGENERATOR, a multi-target Learning administration framework generator with a model-driven procedure focused around MDA methodology coupled with part approach. Taking into account generative programming, from client determinations (abstract models) and the fancied advances, programming blocks will be created and amassed to deliver a complete arrangement adjusted to zone and clients' necessities. This paper concentrates on the change guidelines actualized in the LMSGENERATOR centers .Also; it introduces a careful investigation to delineate this proposal.

Piezoelectric material based energy harvesting system (EHS) has been designed and developed to study the influence of delamination on EHS in low frequency vibrating beam structures. The stiffness reduction due to the presence of delamination of specified size and its location is evaluated using the harvested energy in different vibrating elastic modes. Four aluminium beam specimens were fabricated, each having two layers of 1 mm thickness and a specified dimension of delamination was introduced by using a thin Teflon film. The beam without delamination is considered to be healthy and served as the reference structure. The PZT-5H patches were surface bonded on the beams to work as energy harvesting transducers. A suitable electronic circuit is developed to receive the energy from the vibrating beam. The experimental results in terms of energy generated by the four laminated beams have been compared with analytical results at resonant conditions and correlated to assess the effect of delamination on energy produced by low frequency vibration modes. The location of delamination has made a significant change in the harvested energy of second and third bendings; in particular, the delaminations at edge and root have displayed a clear trend. Resonant and off-resonant excitations have revealed that the edge delaminated beam produces lower energy output. The current work has demonstrated that energy harvesting from different elastic modes and with a variable frequency at constant force excitation can be a useful health monitoring technique, employing low frequency vibration, besides utilising the harvested energy itself.
