Energy effects of heat-island reduction strategies in Toronto,Canada
The effect of heat-island reduction (HIR) strategies on annual energy savings and peak-power avoidance of the building sector of the Greater Toronto Area is calculated, using an hourly building energy simulation model. Results show that ratepayers could realize potential annual energy savings of over $11M from the effects of HIR strategies. The residential sector accounts for over half (59%) of the total savings, offices 13% and retail stores 28%. Savings from cool roofs are about 20%, shade trees 30%, wind shielding of trees 37%, and ambient cooling by trees and reflective surfaces 12%. These results are preliminary and highly sensitive to the relative price of gas and electricity. Potential annual electricity savings are estimated at about 150GWh and potential peak-power avoidance at 250MW.

Solvent recovery from aqueous effluent using process diluent in the caustic-side solvent extraction (CSSX) process.
In this work, solvent recovery from aqueous CSSX process raffinate effluent was tested using the process diluent (Isopar{reg_sign}L). A model was developed to obtain stage efficiency for the diluent contact stages. The model was used to fit experimental data from a 19.8-hr solvent recovery test. Diluent-in-aqueous entrainment was measured during the test. Vacuum distillation was used to concentrate the solvent components, BOBCalixC6 and modifier, in the diluent used in solvent recovery. Using the results, a feasibility study was performed to compare the annual cost of lost solvent under each of four solvent recovery options. These options were decanter tank, centrifuge, two-stage diluent contact using centrifugal contactor, and no solvent recovery action.

Operational envelope for studies using magnetite to remove strontium and actinides from SRS tank waste.
This work discusses the operational envelope developed for tests involving in-situ formed magnetite to remove strontium (Sr) and actinide from Savannah River Site (SRS) waste solution. These tests will be performed at Argonne National Laboratory (ANL) in support of the SRS effort for HLW treatment. The operational envelope was developed in consultations with key personnel at SRS. Four elements of the operational envelope were identified: (1) waste simulant composition, (2) radionuclide concentrations and oxidation states, (3) minimum DF requirements, and (4) the maximum amount of magnetite that can be used per liter of waste.

Virtual data in CMS production
Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: (1) a Virtual Data Language, which is used to describe virtual data products, (2) a Virtual Data Catalog, which is used to store virtual data entries, (3) an Abstract Planner, which resolves all dependencies of a particular virtual data product and forms a location and existence independent plan, (4) a Concrete Planner, which maps an abstract, logical plan onto concrete, physical grid resources accounting for staging in/out files and publishing results to a replica location service. A CMS Workflow Planner, MCRunJob, is used to generate virtual data products using the Virtual Data Language. Subsequently, a prototype workflow manager, known as WorkRunner, is used to schedule the instantiation of virtual data products across a grid.

Improved Measurements of Neutral B Decay Branching Fractions to K0s pi+ pi- and the Charge Asymmetry of B0 -> K*+ pi-
The authors analyze the decay B{sup 0} {yields} K{sub S}{sup 0}{pi}{sup +}{pi}{sup -} using a sample of 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. A maximum likelihood fit finds the following branching fractions: {Beta}(B{sup 0} {yields} K{sup 0}{pi}{sup +}{pi}{sup -}) = (43.0 {+-} 2.3 {+-} 2.3) x 10{sup -6}, {Beta}(B{sup 0} {yields} f{sub 0}({yields} {pi}{sup +}{pi}{sup -})K{sup 0}) = (5.5 {+-} 0.7 {+-} 0.5 {+-} 0.3) x 10{sup -6} and {Beta}(B{sup 0} {yields} K*{sup +}{pi}{sup -}) = (11.0 {+-} 1.5 {+-} 0.5 {+-} 0.5) x 10{sup -6}. For these results, the first uncertainty is statistical, the second is systematic, and the third (if present) is due to the effect of interference from other resonances. They also measure the CP-violating charge asymmetry in the decay B{sup 0} {yields} K*{sup +}{pi}{sup -}, {Alpha}{sub K*{pi}} = -0.11 {+-} 0.14 {+-} 0.05.

Measurement of the B0 to pi l nu and B+ to pi0 l nu Branching Fractions and Determination of |Vub| in Upsilon(4S) to BBbar Events Tagged by a Fully Reconstructed B Meson
The authors report preliminary measurements of the charmless exclusive semileptonic branching fractions of the B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu} and B{sup +} {yields} {pi}{sup 0}{ell}{sup +}{nu} decays, based on 211 fb{sup -1} of data collected at the {Upsilon}(4S) resonance by the BABAR detector. In events in which the decay of one B meson to a hadronic final state is fully reconstructed, the semileptonic decay of the second B meson is identified by the detection of a charged lepton and a pion. They measure the partial branching fractions for B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu} and B{sup +} {yields} {pi}{sup 0}{ell}{sup +}{nu} in three regions of the invariant mass squared of the lepton pair, and they obtain the total branching fractions {Beta}(B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}) = (1.14 {+-} 0.27{sub stat} {+-} 0.17{sub syst}) x 10{sup -4} and {Beta}(B{sup +} {yields} {pi}{sup 0}{ell}{sup +}{nu}) = (0.86 {+-} 0.22{sub stat} {+-} 0.11{sub syst}) x 10{sup -4}. Using isospin symmetry, they measure the combined total branching fraction {Beta}(B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}) = (1.28 {+-} 0.23{sub stat} {+-} 0.16{sub syst}) x 10{sup -4}. Theoretical predictions of the form-factor are used to determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |V{sub …

Measurements of the B to Xs gamma Branching Fraction and Spectral Shape from a Sum of Exclusive Final States
Using 88.9 million B{bar B} events collected by the BABAR detector at the {Upsilon}(4S), they measure the branching fraction for the radiative penguin process B {yields} X{sub s}{gamma} from the sum of 38 exclusive final states. The inclusive branching fraction above a minimum photon energy E{sub {gamma}} > 1.9 GeV is {Beta}(b {yields} s{gamma}) = (3.27 {+-} 0.18(stat.){sub -0.40}{sup +0.55}(syst.){sub -0.09}{sup +0.04}(theory)) x 10{sup -4}. They also measure the isospin asymmetry between B{sup -} {yields} X{sub s{bar u}}{gamma} and {bar B}{sup 0} {yields} X{sub sd}{gamma} to be {Delta}{sub 0-} = -0.006 {+-} 0.058(stat.) {+-} 0.009(syst.) {+-} 0.024({bar B}{sup 0}/B{sup -}). The photon energy spectrum is measured in the B rest frame, from which moments are derived for different values of the minimum photon energy. They present fits to the photon spectrum and moments which give the heavy-quark parameters m{sub b} and {mu}{sub {pi}}{sup 2}. The fitted parameters are consistent with those obtained from semileptonic B {yields} X{sub c}{ell}{nu} decays, and are useful inputs for the extraction of |V{sub ub}| from measurements of semileptonic B {yields} X{sub u}{ell}{nu} decays.

Search for Lepton Flavor Violation in the Decay tau -> electron gamma
A search for the non-conservation of lepton flavor in the decay {tau}{sup {+-}} {yields} e{sup {+-}}{gamma} has been performed with 2.07 x 10{sup 8} e{sup +}e{sup -} {yields} {tau}{sup +}{tau}{sup -} events collected by the BABAR detector at the PEP-II storage ring at a center-of-mass energy near 10.58 GeV. They find no evidence for a signal and set an upper limit on the branching ratio of {Beta}({tau}{sup {+-}} {yields} e{sup {+-}}{gamma}) < 1.1 x 10{sup -7} at 90% confidence level.

Simulation of Phase Effects in Imaging for Mesoscale NDE
High energy density experiments, such as those planned at the National Ignition Facility (NIF), use mesoscale targets with the goals of studying high energy density physics, inertial confinement fusion, and the support of national security needs. Mesoscale targets are typically several millimeters in size and have complex micrometer-sized structures composed of high-density metals and low-density foams and ices. These targets are designed with exacting tolerances that are difficult to achieve at present. Deviation from these tolerances can result in compromise of experimental goals and thus it is necessary to determine as-built properties of these targets using NDE techniques. Radiography and computed tomography are being used to investigate these targets, but the mix between phase and absorption information is difficult to separate, making interpretation of results difficult. We have recently improved the HADES radiographic simulation code to include phase in simulations, as an aid for doing NDE on mesoscale targets. In this paper we report on how we extended HADES to incorporate phase effects, and compare simulations with a variety of experimental test results.

Composite Amplitude Modulated Phase Only Filter Based Detection and Tracking of the Back-Reflection of KDP Images
An algorithm for determining the position of the KDP back-reflection image was developed. It was compared to a centroid-based algorithm. While the algorithm based on centroiding exhibited a radial standard deviation of 9 pixels, the newly proposed algorithm based on classical matched filtering (CMF) and a Gaussian fit to correlation peak provided a radial standard deviation of less than 1 pixel. The speed of the peak detection was improved from an average of 5.5 seconds for Gaussian fit to 0.022 seconds by using a polynomial fit. The performance was enhanced even further by utilizing a composite amplitude modulated phase only filter; producing a radial standard deviation of 0.27 pixels. The proposed technique was evaluated on 900+ images with varying degrees of noise and image amplitude as well as real National Ignition Facility (NIF) images.
