Bufferless NOC Simulation of Large Multicore System on GPU Hardware
Navin Kumar,Aryabartta Sahu
Computer Science , 2015,
Abstract: Last level cache management and core interconnection network play important roles in performance and power consumption in multicore system. Large scale chip multicore uses mesh interconnect widely due to scalability and simplicity of the mesh interconnection design. As interconnection network occupied significant area and consumes significant percent of system power, bufferless network is an appealing alternative design to reduce power consumption and hardware cost. We have designed and implemented a simulator for simulation of distributed cache management of large chip multicore where cores are connected using bufferless interconnection network. Also, we have redesigned and implemented the our simulator which is a GPU compatible parallel version of the same simulator using CUDA programming model. We have simulated target large chip multicore with up to 43,000 cores and achieved up to 25 times speedup on NVIDIA GeForce GTX 690 GPU over serial simulation.
Radioactive Branching Using Dice  [PDF]
Sarmistha Sahu
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.35099
Abstract: Dice rolling (Emeric,1997) is a useful pedagogical tool (Arthur & Ian,2012; Todd, Clifton, Ingrid, Zdravko,2006)) to introduce students to the concepts and essential features of radioactivity. It can be extended to explain radioactive branching. In the process, the students learn about half life, decay constant and activity of a radioactive substance. Terms like stochastic processes, probability of decay, statistical fluctuations, and mutually exclusive processes; becomes clear in this process.
Tilted Bianchi Type VI0 Cosmological Model in Saez and Ballester Scalar Tensor Theory of Gravitation  [PDF]
Subrata Kumar Sahu
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.11008
Abstract: Tilted Bianchi type VI0 cosmological model is investigated in a new scalar tensor theory of gravitation pro-posed by Saez and Ballester (Physics Letters A 113:467, 1986). Exact solutions to the field equations are derived when the metric potentials are functions of cosmic time only. Some physical and geometrical proper-ties of the solutions are also discussed.
Study of Morphology and Agar Contents in Some Important Gracilaria Species of Indian Coasts  [PDF]
Nivedita Sahu, Dinabandhu Sahoo
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.412A2007
Abstract:

This study reports the morphological, anatomical and agar content difference among various species of Gracilaria. The cortex was found 1-2 layered in G. edulis and G. eucheumatoides whereas 5-6 layered in G. foliifera and G. crassa. The medulla was 6-8 layered in G. edulis, 10-11 layered in G. foliifera, 14-15 layered in G. eucheumatoides and 8-10 layered in G. crassa. Similarly, distinct variations were observed in the structure of cystocarp of these taxa. The outer pericarp was 6-8 layered in G. verrucosa (attached type), 8-9 in Graciriopsis megaspora, 12-13 layered cells in G

Endovascular and Percutaneous Management of the Pseudoaneurysms  [PDF]
Sahu Chandradev, Singhal Ateesh
Open Journal of Radiology (OJRad) , 2014, DOI: 10.4236/ojrad.2014.43032
Abstract:

Introduction: Pseudoaneurysm is a dilatation of an artery with actual disruption of one or more layers of its wall, rather than just expansion of wall layers. Pseudoaneurysms are common vascular abnormalities. Computed Tomography (CT), Magnetic Resonance Imaging (MRI), sonography, and angiography all are valuable modalities in the imaging workup of pseudoaneurysms. Conventional angiography remains the gold standard for diagnosis. Therapeutic options have evolved in recent years from the traditional surgical option toward a less invasive approach which includes procedures such as Ultrasound (US)-guided compression, US-guided percutaneous thrombin injection, and endovascular management (embolization, stent-graft placement and endovascular coiling). Objective: In this article, we discuss pseudoaneurysms of various arteries, and available percutaneous and endovascular treatment options. Materials and Methods: Sixteen patients diagnosed with pseudoaneurysm involving visceral and peripheral arteries were included in this study. The initial diagnosis was made with CDUS, CECT, and CTA followed by catheter angiogram for therapeutic procedures. Results: All the 16 patients with pseudoaneurysms were successfully treated with endovascular and percutaneous embolization to achieve stasis. Conclusion: CT, MRI, sonography, and angiography may all be valuable in the imaging workup of pseudoaneurysms. The use of minimally invasive treatment has led to a marked decrease in the morbidity and mortality rates for pseudoaneurysms.

Low Density Instability in Asymmetric Nuclear Matter Using Pion Dressing  [PDF]
S. K. Sahu
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.69140
Abstract: We study the asymmetric nuclear matter in a nonperturbative manner. The bulk nuclear matter studied by the consistent exchange of σ, ω and π mesons is used to investigate its stability. The equation of state (EOS) at zero temperature is considered to study the symmetry energy, curvature parameter of symmetry energy and asymmetry energy. The effect of the density dependence of the symmetry energy on instability property is investigated and analyzed using proton fraction in the nuclear matter. Here a microscopic density-dependent model of the nucleon-meson coupling is used to reexamine the instability of asymmetric nuclear matter.

Saroj Kumar Sahu
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.310159
Abstract: We study the asymmetric nuclear matter in a nonperturvative manner at finite temperatures using thermofield dynamics method. The nucleon-meson interaction is taken to examine the binding energy (EB), pressure (P) for various proton fractions.
A Simple Model of Currency Notes Withdrawal  [PDF]
Siddhartha Chattopadhyay, Sohini Sahu
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.814198
Abstract: In the backdrop of the demonetization move by the Government of India, this paper proposes a model of optimal currency holding when there is a possibility of currency withdrawal. Our results indicate that if the perceived probability of withdrawal of higher denomination currency is very high, then agents would eventually hold cash in lower denomination currency only, thereby making the higher currency notes redundant. Thus, one of the targets of demonetization, which is less holding of higher currency notes, can be achieved without actually implementing demonetization.
Lateral approach for supraclavicular brachial plexus block
Sahu D,Sahu Anjana
Indian Journal of Anaesthesia , 2010,
Abstract: A lateral approach described by Volker Hempel and Dr. Dilip Kotharihas been further studied, evaluated and described in detail in the present study. The aim of this study was to evaluate lateral approach of supraclavicular brachial plexus block, mainly in terms of successes rate and complication rate. The study was conducted in secondary level hospital and tertiary level hospital from 2004 to 2008. It was a prospective nonrandomized open-level study. Eighty-two patients of both sexes, aged between 18 and 65 years with ASA Grade I and II scheduled to undergo elective major surgery of the upper limb below the midarm, were selected for this new lateral approach of brachial plexus block. The onset and duration of sensory and motor block, any complications and need for supplement anaesthesia were observed. Success and complication rate were calculated in percentage. Average onset and duration of sensory and motor block was calculated as mean ± SD and percentage. Out of 82 patients, 75 (92%) have got successful block with no significant complication in any case.
A Practical Solution for Location Estimation in Manually Deployed Wireless Sensor Networks  [PDF]
Om Prakash Sahu, Tarun Dubey
Wireless Sensor Network (WSN) , 2011, DOI: 10.4236/wsn.2011.34013
Abstract: This paper addresses the existing research and adds another aspect of functionality by incorporating pertinent sensor nodes to provide a dynamic location discovery and estimation. The software used provides an easy graphical user interface to visualize a particular location in accordance with geographical latitude and longitude. A simple real time location estimation technique is worked out for wireless sensor networks based on manual deployment of sensors. The proposed scheme finds more efficient solutions with less quantity of sensors as compared to existing deployment schemes. The set up is evaluated exclusively in real environments using IRIS sensor nodes supported by a global positioning system module to provide visualization of an outdoor location. The results are offered by Google Earth application.
