Rubina Nasir,Faiza Aziz,Sikander M. Mirza,Nasir M. Mirza 한국원자력학회 2018 Nuclear Engineering and Technology Vol.50 No.3

Experimental measurements of the response of BF3 detector to a 3 Ci AmeBe neutron source for threedifferent reflecting materials, i.e., aluminum, wood, and Perspex of varying thicknesses have been carriedout. The varying contribution of wall effect to the response due to change in active volume of the detectorhas also been determined experimentally. Then, a Monte Carlo code has been developed for the calculationof the neutron response function of the BF3 detector using source biasing and importance sampling. This code simulates the BF3 detector response exposed to the neutron field in a three-dimensionalsource, detector, and reflecting medium configurations. The results of simulation have been comparedwith the corresponding experimental measurements and are found to be in good agreement. Theexperimental neutron albedo measurements for various values of Perspex thickness show saturatingbehavior, and results agree very well with the data obtained by Monte Carlo simulation.

Effect of Kinetic Parameters on Simultaneous Ramp Reactivity Insertion plus Beam Tube Flooding Accident in a Typical Low Enriched U3Si2-Al Fuel based MTR-Type Research Reactor

Rubina Nasir,Sikander M. Mirza,Nasir M. Mirza 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.4

This work looks at the effect of changes in kinetic parameters on simultaneous reactivityinsertions and beam tube flooding in a typical material testing reactor-type researchreactor with low enriched high density (U3Si2-Al) fuel. Using a modified PARET code,various ramp reactivity insertions (from $0.1/0.5 s to $1.3/0.5 s) plus beam tube flooding($0.5/0.25 s) accidents under uncontrolled conditions were analyzed to find their effects onpeak power, net reactivity, and temperature. Then, the effects of changes in kinetic parametersincluding the Doppler coefficient, prompt neutron lifetime, and delayed neutronfractions on simultaneous reactivity insertion and beam tube flooding accidents wereanalyzed. Results show that the power peak values are significantly sensitive to theDoppler coefficient of the system in coupled accidents. The material testing reactor-typesystem under such a coupled accident is not very sensitive to changes in the promptneutron life time; the core under such a coupled transient is not very sensitive to changesin the effective delayed neutron fraction.

Topographic effects on tornado-like vortex

Nasir, Zoheb,Bitsuamlak, Girma T. Techno-Press 2018 Wind and Structures, An International Journal (WAS Vol.27 No.2

The effects of steep and shallow hills on a stationary tornado-like vortex with a swirl ratio of 0.4 are simulated and quantified as Fractional Speed Up Ratios (FSUR) at three different locations of the vortex with respect to the crests of the hills. Steady state Reynolds Averaged Naiver Stokes (RANS) equations closed using Reynolds Stress Turbulence model are used to simulate stationary tornadoes. The tornado wind field obtained from the numerical simulations is first validated with previous experimental and numerical studies by comparing radial and tangential velocities, and ground static pressure. A modified fractional speed-up ratio (FSUR) evaluation technique, appropriate to the complexity of the tornadic flow, is then developed. The effects of the hill on the radial, tangential and vertical flow components are assessed. It is observed that the effect of the hill on the radial and vertical component of the flow is more pronounced, compared to the tangential component. Besides, the presence of the hill is also seen to relocate the center of tornadic flow. New FSUR values are produced for shallow and steep hills.

Viral evolution : Primordial cellular origins and late adaptation to parasitism

Nasir, Arshan,Kim, Kyung Mo,Caetano-Anollé,s, Gustavo Landes Bioscience 2012 Mobile genetic elements Vol.2 No.5

<P>Explaining the origin of viruses remains an important challenge for evolutionary biology. Previous explanatory frameworks described viruses as founders of cellular life, as parasitic reductive products of ancient cellular organisms or as escapees of modern genomes. Each of these frameworks endow viruses with distinct molecular, cellular, dynamic and emergent properties that carry broad and important implications for many disciplines, including biology, ecology and epidemiology. In a recent genome-wide structural phylogenomic analysis, we have shown that large-to-medium-sized viruses coevolved with cellular ancestors and have chosen the evolutionary reductive route. Here we interpret these results and provide a parsimonious hypothesis for the origin of viruses that is supported by molecular data and objective evolutionary bioinformatic approaches. Results suggest two important phases in the evolution of viruses: (1) origin from primordial cells and coexistence with cellular ancestors, and (2) prolonged pressure of genome reduction and relatively late adaptation to the parasitic lifestyle once virions and diversified cellular life took over the planet. Under this evolutionary model, new viral lineages can evolve from existing cellular parasites and enhance the diversity of the world’s virosphere.</P>

Importance of multifunctional finishing of textiles is increasing day by day due to greater consumer demand. Cross-linker is one of the commonly used finishes agent to impart functionality in textiles. In this research work theperformance of the formaldehyde free carboxylic acid based eco-friendly cross-linkers; citric acid (CA) and maleic acid(MA) was enhanced by incorporating three different types of metal oxides nanoparticle (ZnO, MgO and CaO). Two differentfixation methods of pad-dry-cure with and without UV irradiation were used. ZnO along with CA and MA was found to bemost effective in increasing crease recovery performance of the cotton fabric followed by MgO while CaO was found to beineffective. Fabric tear strength was also improved by the incorporation of these nanoparticles. Additionally, incorporation ofthese nanoparticles exhibited improvement in the fabric handle and antimicrobial properties.

Unorthodox Approach to Classify EEG Signals for Upper Limb Prosthesis Application

Nasir Rashid,Fahad Mahmood,Javaid Iqbal 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10

Brain computer interface (BCI) is targeted for decoding the EEG (Electroencephalogram) signals that the human brain generates which are beneficial for the paraplegic patients. These EEG signals are slow cortical potentials that are directly recorded from scalp thus cortical neuronal activity is explored via non-invasive electrodes. These EEG signals are then further utilized for performing various operations which the paraplegic patients are unable to perform. This research article presents a novel architecture of classification of four finger movements (thumb movement, index finger movement, middle and index finger combined movement and fist movement) of the right hand on the basis of EEG (Electroencephalogram) data of the movements. The presented architecture utilizes Guided filter for reduction of noise (artefacts) from EEG signals alpha and beta band (8-30 Hz). As this band contains the maximum information of movement in terms of motor imagery. Rank Transform is employed as feature extraction approach for further enhancement of processed EEG signals. Two stage Logistic Regression classifier is finally employed for classification of movements using processed EEG signals. The experimental results demonstrate the accuracy, robustness and computational complexity of the proposed approach and have significant improvement as compared with recent architectures for EEG classification.

Nasir Ganikhodjaev,Ashraf Mohamed Nawi,Mohd Hirzie Mohd Rodzhan 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.7

We study the phase diagrams for the Potts model with restricted competing nearest-neighbor interactions <i>J</i>₁ and ternary interactions <i>J_pt</i> on a Cayley tree of arbitrary order <i>k</i>. At vanishing temperature, the phase diagram is fully determined for all values and signs of <i>J_pt</i>/<i>J</i>₁ and <i>T</i>/<i>J</i>₁. The phase diagrams are obtained from stability conditions, and characteristic points in the iteration scheme are numerically analyzed. The wavevectors versus temperature are plotted for some critical points in the modulated phases. Then, we using the Lyapunov exponent to verify the stability of the periods.
