On the Clustering of GRBs on the Sky

The two-point correlation of the 4th (current) BATSE catalog (2494 objects) is calculated. It is shown to be consistent with zero at nearly all angular scales of interest. Assuming that GRBs trace the large scale structure in the universe we calculate the angular correlation function for the standard CDM (sCDM) model. It is shown to be $\le 10^{-4}$ at $\theta \simeq 5^\circ$ if the BATSE catalog is assumed to be a volume-limited sample up to $z \simeq 1$. Combined with the error analysis on the BATSE catalog this suggests that nearly $10^5$ GRBs will be needed to make a positive detection of the two-point angular correlation function at this angular scale.Comment: 5 pages, Latex with aipproc.sty, incl. 1 ps-Fig., Proc. of the 5th Huntsville Gamma Ray Burst Symposium, Oct. 1999, ed.

A statistical analysis of corpus based approach on learning sentence patterns

This research paper examines the adverse effect of theoretical explanation of the grammatical rules among the learners. Exploration of the methods and materials taught inductively or deductively is the panacea to achieve the required goal. The study throws light on the pedagogical implication of adopting appropriate methods and materials for building the learners’ grammar and language. It primarily intends to explore a new teaching method using language corpora that can be employed in the English grammar classes in colleges at the undergraduate level. It strives to evaluate the effectiveness of teaching sentence patterns through corpus based activities comparing with the traditional based teaching. Thus the methodology aims to encourage students to become independent corpus users

Spontaneous isolated bladder rupture following normal delivery

Spontaneous bladder rupture in a primipara after normal delivery within the first week of puerperium is a rare surgical emergency. The importance of suspecting and recognizing the voiding dysfunction in the postpartum period and early catheterisation to prevent such catastrophe is highlighted in this case report. We report a case of spontaneous intraperitoneal bladder rupture in a 26 year old primipara 3 days after normal delivery of a 3kg baby with episiotomy

Document Indexing Strategies in Big Data A Survey

From past few years, the operations of the Internet have a significant growth and individuals, organizations were unaware of this data explosion. Because of the increasing quantity and diversity of digital documents available to end users, mechanism for their effective and efficient retrieval is given highest importance. One crucial aspect of this mechanism is indexing, which serves to allow documents to be located quickly. The problem is that users want to retrieve on the basis of context, and individual words provide unreliable evidence about the contextual topic or meaning of a document. Hence, the available solutions cannot meet the needs of the growing heterogeneous data in terms of processing. This results in inefficient information retrieval or search query results. The design of indexing strategies that can support this need is required. There are various indexing strategies which are utilized for solving Big Data management issues, and can also serve as a base for the design of more efficient indexing strategies. The aim is to explore document indexing strategy for Big Data manageability. The existing systems like, Latent Semantic Indexing , Inverted Indexing, Semantic indexing and Vector Space Model has their own challenges such as, Demands high computational performance, Consumes more memory Space, Longer data processing time, Limits the search space, will not produce the exact answer, Can present wrong answers due to synonyms and polysemy, approach makes use of formal ontology. This paper will describe and compare the various Indexing techniques and presents the characteristics and challenges involved

Characterization and Phase Transitions of Bi Doped BaTiO3 Ceramics Prepared through Chemical Route

Nano particulate Barium Bismuth Titanate (BaBixTi1-xO3-õ) materials (with x=0.05, 0.1 and 0.15) were prepared through sol-gel chemical route (Pichini method) and the XRD patterns were indexed on the basis of tetragonal-BaTiO3 phase. In higher Bi-content secondary peak was observed. In the study of lattice parameters, C-parameter is found to be decrease with  Bi-content. With increasing in the Bi-content the percentage of secondary absorption peak is increases. The microstructure of the samples was  investigated by using Scanning electron microscope (DSC). The grain size range was 80 nm for the dried gel powder and 1-1.5 µm for the powder  calcined at . 1150‹C. Infrared (IR) spectrum was recorded at room  temperature with Thermo Nicolet Nexus 670 FTIR spectrometer. The secondary absorption peak observed at 435 cm-1 was found to decrease with Bi-content. In the study of lattice parameters, C-parameter was found to be decrease with Bi-content

Bright Lesion Detection in Color Fundus Images Based on Texture Features

In this paper a computer aided screening system for the detection of bright lesions or exudates using color fundus images is proposed. The proposed screening system is used to identify the suspicious regions for bright lesions. A texture feature extraction method is also demonstrated to describe the characteristics of region of interest. In final stage the normal and abnormal images are classified using Support vector machine classifier. Our proposed system obtained the effective detection performance compared to some of the state–of–art methods

A Comparative clinical evaluation of Sirodhara with Sukhosnajala, Tila Tailam and Brahmi Tailam in the management of mild to moderate essential hypertension

In worldwide 25 percentage of population is suffering with Hypertension. As it is an instrumental disease, asymptomatic in nature, it was named as Silent killer. The causative factors of Essential hypertension were Genetic predisposition and environmental factors but these factors are triggered by stress hence it comes under stress related psycho-somatic disorder. In Hypertensive patients, Decrease in 5mm of Hg in SBP and DBP results in decrease in cardiovascular risk, stroke which decreases mortality rate worldwide. The management aspect of modern medical science remains symptomatic with troublesome side effects. The Joint National Committee (JNC 8) guideline advise higher blood pressure goals, less use of several types of antihypertensive medications and suggests lifestyle modification and relaxation are the best initial therapy. In Ayurveda, Shirodhara is one of the panchakarma therapy meant for relaxation and stress reducing procedure mentioned in Dharakalpaas a preventive and curative treatment for many stress related disorders. So, Present study is planned as “A Comparative clinical evaluation of Shirodhara with Sukhos̩n̩ajala, Tila tailam and Brahmitailamin the management of mild to moderate essential hypertension”was selected. This paper is going to describe about conclusion drawn from the study i.e. effect of three types of dhara on Objective parameters SBP, DBP, PP, and MAP

A Note on Implementing Recurrence Quantification Analysis for Network Anomaly Detection

This paper deal with the network anomaly detection, based on the analysis of non-stationary properties that occur in the aggregated IP traffic flows. We use recurrence quantification analysis (RQA), a mathematical nonlinear technique to achieve this task. The objective is to model the standard network traffic and report any deviation from it. We create a baseline from which we derive the RQA parameters. Using these parameters we explore the hidden recurrence patterns in the network traffic. Further, the detection is analysed using the support vector machine to classify the deviations from the regular traffic. Experiments are conducted on Vellore Institute of Technology University campus network traffic data to validate the model.Defence Science Journal, 2012, 62(2), pp.112-116, DOI:http://dx.doi.org/10.14429/dsj.62.117
