Experimental and theoretical study of BF3 detector response for thermal neutrons in reflecting materials

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.

Nasir, Tuqeer,Kim, Bum Jun,Kim, Kwan-Woo,Lee, Sang Hoon,Lim, Hyung Kyu,Lee, Dong Kyu,Jeong, Byung Joo,Kim, Hak Chul,Yu, Hak Ki,Choi, Jae-Young The Royal Society of Chemistry 2018 Nanoscale Vol.10 No.46

<P>The fundamental issues related to the formation of mechanical cracks and the chemical residue during the transfer process of large-area CVD graphene by polymeric carrier-films are addressed in this work. This paper presents a method to design a new polymer carrier-film (using polystyrene (PS) and 4,4′-diisopropylbiphenyl (DIPB)) that is free from mechanical cracks and polymer residue during the transfer of large-area graphene from a metal catalyst. This new polymer carrier film shows excellent mechanical flexibility and good solubility in tetrahydrofuran solvent without any residue and it is confirmed that the graphene transfer process is excellent without mechanical destruction even over a large area. Our result gave a technical milestone for the real industrial application of graphene in many application areas (not only graphene but also several two-dimensional materials such as boron nitride, transition metal di-chalcogenide, and black phosphorus).</P>

Status of Exotic Flora in Kashmir Valley

Nasir Rashid Wani,Shah Murtaza Mushtaq 강원대학교 산림과학연구소 2012 Journal of Forest Science Vol.28 No.1

The Kashmir Himalaya, known for its indigenous and endemic flora, also provides home to a large number of exotic plants, which exhibit a wide taxonomical and distributional stretch. Although, some preliminary studies have been carried out in the region on some aspects of its exotic flora, the inventorization and documentation of its exotic have received a little or negligible attention. There is a lot of scope of these exotic plant species in Kashmir valley, but lack of authentic identification has been as a big hurdle in their scientific management. It is in this backdrop that the present floristic study was carried out to identify, inventorize, document and characterize the exotic plant species grown in the Valley. The present study has revealed that Kashmir Valley grows 317 exotic plant species, which belong to 209 genera in 85 families. Dicotyledons are the largest group, represented by 252 species in 163 genera and 67 families. Monocotyledons comprise 52 species in 37 genera and 13 families. Gymnosperms are the smallest group, with 13 species distributed in 9 genera and 5 families. Asteraceae is the largest family containing 33 exotic species.

In this rapidly growing and competitive technological development world, business incubation is a very supportive and productive tool for promoting the entrepreneurial environment, job creation and economic development. The efficacy of incubators is a crucial aspect for boosting the speed of local, regional and national economies and SMEs development. This study argues to suggest that efficiency of business incubators is vital for actively contributing in economic development especially for developing countries, namely China. A document analysis and archives based survey was conducted to review and analyse the practices of business incubators, as well as their strengths and weaknesses. Finally, the findings of the study reveal some future directions of business incubators in China with policy recommendations.

Path-Following Algorithms for Beamforming and Signal Splitting in RF Energy Harvesting Networks

Nasir, Ali A.,Tuan, Hoang D.,Ngo, Duy T.,Durrani, Salman,Kim, Dong In IEEE 2016 IEEE COMMUNICATIONS LETTERS Vol.20 No.8

<P>We consider the joint design of transmit beamforming and receive signal-splitting ratios in the down-link of a wireless network with simultaneous radio frequency information and energy transfer. Under constraints on the signal-to-interference-plus-noise ratio at each user and the total transmit power at the base station, the design objective is to maximize either the sum harvested energy or the minimum harvested energy. We develop a computationally efficient path-following method to solve these challenging nonconvex optimization problems. We mathematically show that the proposed algorithms iteratively progress and converge to locally optimal solutions. Simulation results further show that these locally optimal solutions are the same as the globally optimal solutions for the considered practical network settings.</P>

Effect of Underlying Bi₂Se₃ Surface on Magnetic Properties of Ni Films

Nasir, Alviu Rey,Yoo, Taehee,Bac, Seul-Ki,Lee, Hakjoon,Lee, Sangyeop,Choi, Seonghoon,Lee, Sanghoon,Liu, Xinyu,Dobrowolska, M.,Furdyna, Jacek K. IEEE 2017 IEEE transactions on magnetics Vol.53 No.11

<P>We have investigated magnetic properties of Ni film specimens deposited either on GaAs or on Bi2Se3 surfaces. The magnetization saturation field along the out-of-plane direction observed in the Hall data was weaker for the Ni/Bi2Se3 sample than for the Ni/GaAs sample. On the other hand, planar Hall resistance measurements showed the larger in-plane coercive field for Ni/Bi2Se3 than for Ni/GaAs. These changes of magnetic hardness observed along the out-of-plane and in-plane directions in the Ni/Bi2Se3 specimen are consistent with effects arising from spin-orbit interaction at the surface of the Bi2Se3 topological insulator.</P>

Arguments Reinforcing the Three-Domain View of Diversified Cellular Life

Nasir, Arshan,Kim, Kyung Mo,Da Cunha, Violette,Caetano-Anollé,s, Gustavo Hindawi Publishing Corporation 2016 Archaea Vol.2016 No.-

<P>The archaeal ancestor scenario (AAS) for the origin of eukaryotes implies the emergence of a new kind of organism from the fusion of ancestral archaeal and bacterial cells. Equipped with this “chimeric” molecular arsenal, the resulting cell would gradually accumulate unique genes and develop the complex molecular machineries and cellular compartments that are hallmarks of modern eukaryotes. In this regard, proteins related to phagocytosis and cell movement should be present in the archaeal ancestor, thus identifying the recently described candidate archaeal phylum “Lokiarchaeota” as resembling a possible candidate ancestor of eukaryotes. Despite its appeal, AAS seems incompatible with the genomic, molecular, and biochemical differences that exist between Archaea and Eukarya. In particular, the distribution of conserved protein domain structures in the proteomes of cellular organisms and viruses appears hard to reconcile with the AAS. In addition, concerns related to taxon and character sampling, presupposing bacterial outgroups in phylogenies, and nonuniform effects of protein domain structure rearrangement and gain/loss in concatenated alignments of protein sequences cast further doubt on AAS-supporting phylogenies. Here, we evaluate AAS against the traditional “three-domain” world of cellular organisms and propose that the discovery of Lokiarchaeota could be better reconciled under the latter view, especially in light of several additional biological and technical considerations.</P>

Nasir Ali,Rasool Imran,Sibtain Daud,Kamran Raheel 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.5

This paper is presenting an Adaptive Fractional Order PID (AFOPID) controller for PV connected grid system. The proposed controller is designed to harvest maximum power from the PV source. AFOPID controller contain the property of conventional PID controller, where the controller contains an adaptive property to optimize gain parameter on the basis of generator and grid side parameter in view. In the suggested work, the AFOPID controller imparted with the characteristic to get tune with particle swarm optimization to track maximum power point tracking, dc link voltage, and current control and quadrature axis modeling. Furthermore, the current control functionalities are performed through an AFOPID, where the controlling parameters are updated by measured error at every instant. The aim of this research is to attain maximum power from the PV source under varying weather conditions with minimum total harmonic distortion, which validate the performance of the proposed controller. The proposed work is compared with, FOPID, FLC, PI, GA and ACO tune FOPID controllers.
