Section- 1. Introduction Data of different data types such as text, audio, video are present in large amounts in multimedia databases .Ordering or retrieving such date is quite tedious and time consuming. Hence there should be an efficient indexing mechanism for easier retrieval of such data objects. There are various indexing techniques. The paper presents various efficient indexing techniques multimedia database comparing and contrasting them. Section- 2. The time taken by query to retrieve the

B-TREES B-tree is a tree data structure that keeps data sorted and allows searches, insertions, and deletions in logarithmic amortized time. The main idea of using B-Trees is to reduce the number of disk accesses. It is optimized for systems that read and write large blocks of data B- trees are: • Balanced – It is a self-balancing data structure, which means that performance can be guaranteed when B-Trees are utilized. • Broad –B-Trees are broad and expand horizontally instead of vertically.

Figurative Language in A Work of Artifice by Marge Piercy     "A clever trick, crafty device, or stratagem" is how Webster's Encyclopedia of Unabridged Dictionary of the English Language defines Artifice. Marge Piercy definitely used "crafty" techniques in writing "A Work of Artifice." In this poem, Piercy reflects on the growth of a bonsai tree, considering the molded existence of what it is to what it could have naturally been. With deeper analysis of this poem, the correlation between a

With distinctive use of diction, imagery, and figurative language, Frost manages to indirectly understand his way of perceiving life. His view of the normality and repetition that exists everyday is hidden within words written. When seeing Birch trees, bent by the cumbersome snow of the long winter, Frost likes to imagine a boy’s “been swinging them” (Frost, 3). This is a portrayal of his desire to escape the mundane characteristics of everyday life, and enjoy himself by imagining the boy “riding

his father’s trees/By riding them down over and over again/Until he took the stiffness out of them,/And not one hung limp, not one was left/For him conquer,” (28-32). Interpreting this double entendre, it can be seen as man conquering nature. In the endings of Part Two he explains, “He always kept his poise/To the top branches, climbing carefully/With the same pains you use to fill a cup/Up to the brim, and even above the brim,” (35-39). The boy becomes better at swinging the trees, he keeps "his

Robert Frost manipulates images of the wilderness and birch trees in order to convey a sense of nostalgia that evokes a sentimental sense of remembrance through visual and auditory imagery. To begin with, Frost uses the image of birch trees being bent in order to elicit a sentimental response. This plays into the representations that is his perception. For example, Frost describes how the natural bending of birch trees by ice- storms is done by what he likes to depict as “some boy’s been swinging

continues endlessly in a way that makes it hard to tell whether this is an island or the mainland. There is no boat in sight, and so you decide to head into the forest to find some sort of civilization. As soon as you step under the canopy of the trees, the temperature seems to drop by about ten degrees. You walk farther in with no clear direction in mind. Turning around, you find that you can no longer see the beach, and realize that maybe walking in without a plan was not such a good idea. At

accurately measure the distance from one flag to the next, and also to measure the circumference of the trees we were interested in. We had to measure the tree density using a point quarter method, direct count method, and also a random pair method. For each method we did not include trees that were death or trees having a diameter that was less that 10cm. There were four different types of trees in the area in which we were collecting our data form. The various types included White Ash, American

are completely lost in a clear deserted meadow, with no trees, bushes or anything. The girls are drained out of ideas and have no other thoughts in their brains, but to backtrack themselves back to where the started. After peaking themselves up every single pipe opening they have arrived back to where they started. The girls are befuddled and have less than a day to figure something out. Tanya and Eli thought outside the box and used the trees to their advantage as they climbed through the top branches
