The very massive X-ray bright binary system Wack 2134 (= WR 21a)
No full textFrom the radial velocities of the N ivλ4058 and He iiλ4686 emission lines, and the N vλ4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-ray bright emission line star Wack 2134 (= WR 21a) is a spectroscopic binary system with an orbital period of 31.673 ± 0.002 d . With this period, the N iv and He ii emission and N v absorption lines, which originate in the atmosphere of the primary component, define a rather eccentric binary orbit (e = 0.64 ± 0.03) . The radial velocity variations of the N v absorptions have a lower amplitude than those of the He ii emission. Such a behaviour of the emission line radial velocities could be due to distortions produced by a superimposed absorption component from the companion. High-resolution echelle spectra observed during the quadrature phases of the binary show H and He ii absorptions of both components with a radial velocity difference of about 541 km s-1. From this difference, we infer quite high values of the minimum masses, of about 87 and 53 M☉ for the primary and secondary components, respectively, if the radial velocity variations of the He ii emission represent the true orbit of the primary. No He i absorption lines are observed in our spectra. Thus, the secondary component in the Wack 2134 binary system appears to be an early O-type star. From the presence of H, He ii and N v absorptions, and N iv and C iv emissions, in the spectrum of the primary component, it most clearly resembles those of Of/WNLha-type stars.<br/

Information fusion for CB defense applications: Challenge and opportunity
No full textInformation fusion aims at a synergistic exploitation of multiple information sources, to enable decision-making or to enhance its performance. The sources include sensors of various modalities and characteristics, as well as sources which are not sensors. We discuss the challenges of information fusion, technical directions and approaches that can cope with those challenges, and the opportunities those approaches enable. Several research and development efforts conducted at MIT Lincoln Laboratory over the recent years in the area of information fusion for chemical-biological defense serve as the backdrop for that discussion.National Science Foundation (Grant No. 0329901)United States.

A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Evaluation of the sprinkler irrigation system of the East Course Wack Wack Golf and Country Club
No full textThe field practicum enabled the application of the principles and theories in irrigation engineering in the evaluation of the newly constructed sprinkler irrigation system in the East Course of Wack Wack Golf and Country Club. The study involved the observation on the actual layout of the irrigation lines from the main pump to the sprinkler heads of the laterals as well as evaluation of the efficiency of the sprinkler system through determining the coefficient of uniformity (CU), distribution uniformity (DU) and potential water application efficiency (known as potential application efficiency of the low quarter, PELQ). It also involved the verification and comparison of the computed and actual pipe size and power requirement of the East Course. The CU, DU and PELQ of the system was accomplished by performing catch can test on Hole 5 of the East Course. Scobey’s equation was used to verify the pipe size and power requirement of the whole system. The computed sizes were then compared with the actual sizes used in the East Course. The velocity in the longest straight line pipe of the East Course was also computed to check for the possibility of the occurrence of water hammer. The average value of the three parameters: CU, DU and PELQ of the system were 72.0%, 58.0% and 53.6% respectively. The computed values of the three parameters were below the standard values for CU, DU and PELQ (80% for CU and 70% for DU and PELQ) as recommended by Schwab (1993) and the Irrigation Association (2003). The computed pipe sizes for the 2-inch lateral line, 10-inch main line, 8-inch main line, 6-inch main line and 4-inch main line were smaller (1.15 inches, 6.19 inches, 5.49 inches, 4.96 inches and 3.5 inches respectively) compared to the actual pipe sizes used in the system. This indicates that safety factors were applied in the selection of pipe sizes used in the sprinkler system. Also, safety factors were applied in the selection of pump to be used. The computed value for the pump size (75 hp) is lower than the actual pump size (100 hp) used. Based from the results of the field practicum, there was non-uniform water distribution in the East Course during the period that the field practicum was conducted. This was because of the low pressure that was observed in the pipes during operation. Lower pressure was used since the East Course was still under the renovation process during the conduct of the field practice. The pipe sizes and pump rating used was found appropriate for the sprinkler system. The possibility of the occurrence of water hammer in the longest straight line pipe of the East Course was also found unlikely since the actual velocity of water (1.2 m/s) was lower than the maximum water velocity (1.5 m/s) in the pipe in order to prevent the occurrence of water hammer as recommended by Haman, et al. (2009)
