Electromagnetic properties of the neutrinos in gamma-proton collision at the LHC
We have investigated non-standard and couplings via production in a
collision at the LHC. We obtain 95\% confidence level bounds on and couplings by considering three
different forward detector acceptances; , and . We show that the reaction provides more than eight orders of magnitude improvement in
neutrino-two photon couplings compared to LEP limits.Comment: 18 pages, 5 figure
Anomalous WWgamma couplings in gamma-proton collision at the LHC
We examine the potential of pp-> p gamma p -> p W q X reaction to probe
anomalous WWgamma couplings at the LHC. We find 95% confidence level bounds on
the anomalous coupling parameters with various values of the integrated
luminosity. We show that the reaction pp -> p gamma p -> p W q X at the LHC
highly improve the current limits.Comment: 12 pages,3 figure
Top Quark Spin Polarization in e \gamma Collision
We investigate the degree of spin polarization of single top quarks in the
collision via the process
with center of mass energies =0.5, 1 and 1.5 TeV of the parental
linear collider. Dominant spin fractions and spin asymmetries for
the various top quark spin bases are investigated. We show that -beam
direction is the favorite top quark spin decomposition axis. It is found to be
comparable with the ones in and collisions.Comment: 5 pages, 3 figure
Production at Colliders and Anomalous Quartic Coupling
We investigate the constraints on the anomalous quartic
gauge boson coupling through the process .
Considering incoming beam polarizations and the longitudinal and transverse
polarization states of the final W and Z boson we find 95% confidence level
limits on the anomalous coupling parameter with an integrated
luminosity of 500 and =0.5, 1 TeV energies. We show that
initial beam and final state polarizations improve the sensitivity to the
anomalous coupling by up to factors of 2 - 3.5 depending on the energy.Comment: published versio
Anomalous Quartic and Couplings in Collision With Initial Beams and Final State Polarizations
The constraints on the anomalous quartic and
gauge boson couplings are investigated through the processes
and . Considering the
longitudinal and transverse polarization states of the final W or Z boson and
incoming beam polarizations we find 95% confidence level limits on the
anomalous coupling parameters and with an integrated luminosity
of 500 and =0.5, 1 TeV energies. Assuming the
couplings are independent of the
couplings we show that the longitudinal polarization state of the final gauge
boson improves the sensitivity to anomalous couplings by a factor of 2-3
depending on energy and coupling. An extra enhancement in sensitivity by a
factor of 1.3 comes from a set of initial beam polarizations
The effect of electromagnetic properties of neutrinos on the photon-neutrino decoupling temperature
We examine the impact of electromagnetic properties of neutrinos on the
annihilation of relic neutrinos with ultra high energy cosmic neutrinos for the
process. For this process, photon-neutrino
decoupling temperature is calculated via effective lagrangian model beyond the
standard model. We find that photon-neutrino decoupling temperature can be
importantly reduced below the QCD phase transition with the model independent
analysis defining electromagnetic properties of neutrinos.Comment: 12 pages, 3 figures, published versio
An Iterative Cyclic Algorithm for Designing Vaccine Distribution Networks in Low and Middle-Income Countries
The World Health Organization's Expanded Programme on Immunization (WHO-EPI)
was developed to ensure that all children have access to common childhood
vaccinations. Unfortunately, because of inefficient distribution networks and
cost constraints, millions of children in many low and middle-income countries
still go without being vaccinated. In this paper, we formulate a mathematical
programming model for the design of a typical WHO-EPI network with the goal of
minimizing costs while providing the opportunity for universal coverage. Since
it is only possible to solve small versions of the model optimally, we describe
an iterative heuristic that cycles between solving restrictions of the original
problem and show that it can find very good solutions in reasonable time for
larger problems that are not directly solvable.Comment: International Joint Conference on Industrial Engineering and

Design of wave energy converter system with linear generator
International Conference on Computational and Experimental Science and Engineering (ICCESEN) -- OCT 25-29, 2014 -- Antalya, TURKEYsahin, mustafa ergin/0000-0002-5121-6173WOS: 000363011700070It is not wrong to say that wave energy will be one of the most important energy sources to be used in the future, when it is thought that three-quarters of the world is covered by water. the initial investment and maintenance costs are the only expenses, beside not any price have to be paid for the primary energy. the wave energy does not leave any contaminants, as well as it is cheap, clean, environmentally, friendly and a great energy sources. in this study, wave energy converter system which has a four poles linear generator is discussed. the Linear generator model has been designed and created as a portable model. the results obtained from this model were examined
