    Texture classification is very important in image analysis. Content based image retrieval, inspection of surfaces, object recognition by texture, document segmentation are few examples where texture classification plays a major role. Classification of texture images, especially those with different orientation and scale changes, is a challenging and important problem in image analysis and classification. This thesis proposes an effective scheme for rotation and scale invariant texture classification. The rotation and scale invariant feature extraction for a given image involves applying a log-polar transform to eliminate the rotation and scale effects, but at same time produce a row shifted log-polar image, which is then passed to an adaptive row shift invariant wavelet packet transform to eliminate the row shift effects. So, the output wavelet coefficients are rotation and scale invariant. The adaptive row shift invariant wavelet packet transform is quite efficient with only O (n*log n) complexity. The experimental results, based on different testing data sets for images from Brodatz album with different orientations and scales, show that the implemented classification scheme outperforms other texture classification methods, its overall accuracy rate for joint rotation and scale invariance being 87.09 percent

    Qualitative research can be found in many disciplines and fields, using a variety of approaches, methods and techniques, due to an increasing interest in the application of qualitative research methods it is also used in library and information science (LIS). There are several types of content analysis including qualitative and quantitative content analysis. However quantitative analysis has many limitations, qualitative analysis may be more fruitful procedure. Qualitative research analyses data from direct field work, observations in-depth, open ended interviews and written documents. Qualitative research engaged in naturalistic inquiry and does not manipulate research setting. This article aims that exploring and discussing the possibilities of applying qualitative content analysis as a method in case of study research, features of QCA qualitative v/s quantitative analysis and the use of various software for analyzing text. We concluded that it is important for every phase of the analysis process, including the preparation, organization, and reporting of results

    The unprecedented technological advancement of the 21st century, no doubt has impacted on library services globally and also in India. The Social Media hype has gradually crept into the library profession with social sites such as Facebook, MySpace, Flickr, YouTube, Library Thing, etc; it has become evident that our services will need to change to meet the growing needs of our end users. This paper deals with concept of social networking and its application to Academic library services for a pro-active awareness and training to educate the LIS professional and the Teaching Faculty, Students and Research Scholars on the in valuable importance of utilizing social media in academic library services in digital environment
