An Automation Tool for Single-node and Multi-node Hadoop Cluster
Vaibhav N. Keskar,Amit A. Kathade,Gopal S. Sarda,Amit D. Joshi
Journal of Artificial Intelligence , 2013,
Abstract: Many organisations are required to deal with large data sets. To handle the large data sets these organisations use hadoop cluster. But they need to set up hadoop cluster with different number of nodes several times. This is very common case for many organisations that have just started with hadoop cluster. Setting up hadoop cluster is not a difficult job but requires large human efforts and time. As the number of nodes increases, human efforts and time required also increase. An automation tool which will automate the hadoop cluster set up procedure will be the possible solution to reduce human efforts and time requirement. This study talks about the tool which will automate the hadoop cluster set up procedure. No tool had proved a single operator to install single-node and multi-node cluster.

Seismic Performances of Mountainous Continuous Rigid Frame Solid and Hollow Pier Railway Bridges  [PDF]
Akhil Subedi, Gopal S. Bhandari, Paribesh Parajuli
Open Journal of Civil Engineering (OJCE) , 2018, DOI: 10.4236/ojce.2018.84035
Abstract: This paper focuses on the seismic performance of mountainous railway bridges having different pier type i.e. rectangular hollow piers and solid piers. The piers used were of same materials and inertial properties. For this, 3-D FEM models of these bridges were created by ANSYS 15.0. For seismic assessment, Response Spectrum and Dynamic Time-History Analysis methods were adopted. Different types of earthquake waves used were Elcentro, Wenchuan and Nepal earthquakes, all normalized to 0.3 g Peak Ground Acceleration (PGA). The study concluded that even though the hollow pier bridges are susceptible to large displacements, its dealing with internal forces is remarkable compared to solid pier bridges.

Neurology India , 1999,
Abstract: Forty five patients of multiple sclerosis diagnosed on the basis of Poser′s criteria from West Bengal were studied. The male-female ratio was 1:1.5, mean age of onset 31.83 years in male and 29.11 years in females. The maximum cases were between the 3rd and 4th decade.Definite MS comprised of 60%, while remaining 40% were probable.Visual impairment (53.33%), weakness of limbs (31.11%) and sensory paraesthesia (20%) were the common presenting symptoms whereas pyramidal tract involvement (93.33%) with absent abdominal reflexes (90%) and optic pallor (64.44%) were common signs. Posterior column and spinothalamic sensations were involved in 55% and 51% of cases respectively. Inter-nuclear ophthalmoplegia was present in 6.66% of cases. Pattern of involvement commonly showed three or more sites of lesion. Optico-spinal affection was present in 22.2% of cases. Relapsing and remitting course was found in 48. 91%, relapsing and progressive course in 33.33% and chronic progressive in 17.8%. MRI of brain showed positive results in 16 out of 23 cases. CSF study showed increased positivity in estimation of immunoglobulin level than oligoclonal band. Findings revalidate the disease pattern as being similar to that in other parts of India as well as Asia.

Isolated submandibular gland metastasis from an occult papillary thyroid cancer
Sarda A,Pandey D,Bhalla S,Goyal A
Indian Journal of Cancer , 2004,
Abstract: A case of an isolated submandibular gland metastasis from a clinically occult papillary thyroid carcinoma is described in a 46-year old lady. Initial surgery was done based on the fine needle aspiration cytology (FNAC) report of adenocarcinoma of the submandibular gland. Histopathologic examination of the specimen suggested a metastatic papillary carcinoma. Occult papillary carcinoma in the thyroid was found by multiple blind FNACs. Subsequently to near-total thyroidectomy, no other site of metastasis was found on radio-iodine scanning.
The effect of recent trauma on serum complement activation and serum C3 levels correlated with the injury severity score

Indian Journal of Medical Microbiology , 2004,
Abstract: PURPOSE: The objective of this prospective pilot study was to estimate serum C3 levels and complement activation within 12 hours of injury and to correlate them with abbreviated injury score (AIS) so as to predict the outcome of injury in terms of mortality or sepsis. METHODS: The test group (n=30) of patients with < 12 hours of injury were assessed by the AIS-80 and compared with a control group (n=10). Serum C3 levels were estimated by the single radial immunodiffusion technique and complement activation by both two-dimensional and counter immuno-electrophoresis. Statistical analysis was performed using the correlation regression analysis and the minimum discrimination information statistics (MDIS) analysis. RESULTS: Serum C3 levels were not reduced in patients with injury severity score (ISS) < 12 (n=7). There was a statistically significant difference of serum C3 levels in patients with ISS between 12 and 29 (n=15) and in patients with ISS more than 29 (n=9). Complement activation also correlated well with ISS (p <0.05). Complement activation and serum C3 levels were found to influence subsequent development of septic complications in the post injury period, being significantly lower in patients who developed septic complications. Complement alterations in trauma patients were a direct result of the trauma since they were not seen in patients undergoing surgery. CONCLUSIONS: ISS is a good prognosticator of outcome of trauma and serum C3 levels and complement activation are good predictors for mortality and development of septic complications in recently injured patients. These may prove to be effective parameters in the management of the patients with injury.
A Rapid and Efficient Methodology to Convert Fractured Reservoir Images Into a Dual-Porosity Model Méthodologie rapide et efficace pour convertir les images de réservoir fracturé en modèle à double porosité

Oil & Gas Science and Technology , 2006, DOI: 10.2516/ogst:1998069
Abstract: Both characterization and dynamic simulation of naturally-fractured reservoirs have benefited from major advances in recent years. However, the reservoir engineer is still faced with the difficulty of parameterizing the dual-porosity model used to represent such reservoirs. In particular, the equivalent fracture permeabilities and the equivalent matrix block dimensions of such a model cannot be easily derived from observation of the complex images of natural fracture networks. This paper describes a novel and systematic methodology to compute these equivalent parameters. The results of its implementation with specially-designed software demonstrate its validity and efficiency in dealing with field situations. A tensor of equivalent fracture permeability is derived from single-phase steady-state flow computations on the actual fracture network using a 3D resistor network method and specific boundary conditions. The equivalent block dimensions in each layer are derived from the rapid identification of a geometrical function based on capillary imbibition. The methodology was validated against fine-grid reference simulations with a conventional reservoir simulator. Then, a complex outcrop image of a sandstone formation was processed for demonstration purposes. This innovative tool enables the reservoir engineer to build a dual-porosity model which best fits the hydraulic behavior of the actual fractured medium. La caractérisation et la simulation dynamique des réservoirs naturellement fracturés ont bénéficié d'avancées importantes ces dernières années. Toutefois, l'ingénieur réservoir reste confronté à la difficulté de paramétrer le modèle équivalent à double porosité utilisé pour représenter de tels réservoirs. En particulier, les perméabilités de fracture équivalentes et les dimensions du bloc matriciel équivalent ne peuvent pas être facilement déduites de l'observation des images complexes de réseaux naturels de fractures. Cet article décrit une technique nouvelle et systématique pour calculer ces paramètres équivalents. Les résultats de sa mise en Suvre au moyen d'un logiciel spécifique démontrent sa validité et son efficacité pour l'étude de cas de champ. Un tenseur des perméabilités de fracture équivalentes est déduit de calculs d'écoulements stationnaires et monophasiques dans le réseau réel de fractures, ce dernier étant assimilé à un réseau 3D de résistances et soumis à des conditions aux limites spécifiques. Les dimensions du bloc équivalent dans chaque couche sont obtenues rapidement par identification d'une fonction géométrique représentative d'

Notulae Scientia Biologicae , 2012,
Abstract: Himalayan broad-leaved forests are mainly dominated by oak (Quercus spp.) species. Oak species with other tree species provide numerous ecosystem services and serve as lifeline for local inhabitants. Overall tree diversity and their status in different oak dominated forests viz., Quercus leucotrichophora (1500-2200 m), Q. floribunda (2201-2700 m) and Q. semecarpifolia (2701-3300 m) were studied in Garhwal, Himalaya. A total of 54 tree species (40 genera) in Q. leucotrichophora, 43 tree species (30 genera) in Q. floribunda and 23 tree species (16 genera) in Q. semecarpifolia dominated forests were recorded. Lauraceae was the dominant family in Q. leucotrichophora and Q. floribunda forests (6 and 8 species respectively), while Ericaceae (3 species) was the dominant family in Q. semecarpifolia dominated forests. Pinaceae and Taxaceae were only two gymnospermic family represented by Pinus roxburghii at low, Abies pinrow at mid, Abies spectabilis and Taxus wallichiana at higher elevational oak forests. There was no significant variation (p=0.8) between overall tree density in different oak forests which ranges from 337±51 individual/ha in Q. semecarpifolia to 433±92 individual/ha in Q. leucotrichophora forests. The seedling density has significant variation (p=0.01) in different oak forests where highest density was recorded in Q. leucotrichophora forests (1981 individual/ha) and lowest in Q. semecarpifolia forests (348 individual/ha). The Total Basal Area (TBA) reported from Q. leucotrichophora (88.06 m2/ha) and Q. floribunda (110.5 m2/ha) forests was higher than those of earlier reported from the region, while basal area of Q. semecarpifolia (90.16 m2/ha) was comparable with the forests of western Himalaya.
