Panel on the ASCE/EWRI Standards Practice Documents on Water Resources Alternatives in the Southwest

The EWRI of ASCE has developed numerous standards practice documents or model water codes for water resources alternatives. These include documents on regulated riparian model water, artificial recharge of ground water, atmospheric water management of fog & precipitation & hail suppression, and water infrastructure security enhancements. Others in the development process are on management of the control of erosion and sediment, aquifer storage and recovery, coefficent of conductivity, and concentrate management of desalination. The panel will briefly cover the ASCE standards development process, the ways of obtaining funding for the efforts, the joint effort with other organizations, and some brief details about each document mentioned above

The Deconvolution Analysis of the Radiohippurate Renogram

The evaluation of kidney function is a necessary procedure in assessing the extent of renal disease in today\u27s population. In particular, this assessment should include measurements of the patient\u27s plasma flow into and urine flow from each kidney. Changes in either measurement from accepted normal ranges indicate the presence of a disease process. The combination of radioactive tracer methods with data analysis using models describing biological kinetics has demonstrated the potential of large computers in the assessment of renal function. However, the requirement for sophiticated computer resources has limited the widespread application these techniques might otherwise receive. This work investigates the application of minicomputers for performing this data analysis using digital filtering (deconvolution) methods. A multiparameter compartmental model describing the distribution of 131I-orthoiodohippurate in the renal-vascular system is presented. Differential equations are developed which, when solved, describe the time behavior of this tracer material following its intravenous injection into the body. Analysis of this modeled system shows that only a few parameter values need be identified to characterize the functional vistate of thP renal system in terms of plasma flow and urine flow. The values for these parameter values can be obtained from the renal impulse responses, if these responses are available. Since the renogram can be modeled by a convolution of the renal impulse response with an appropriate renal input function, it follows that isolation of the renal impulse response can be accomplished by deconvolution. The development of this digital filter for performing these deconvolutions is developed in detail. Following the deconvolution of the renogram, the resulting sequence can be analyzed and values assigned to the parameters requiring estimation. These parameter values, in turn, are used to provide measures of plasma flow to and urine flow from each kidney. Computer simulation demonstrated the proper behavior of the deconvolution filter. Clinical application demonstrated the ability to estimate unilateral plasma flow but urine flow could not be computed confidently. In conclusion, it is felt the model does represent an adequate description of hippurate kinetics but does warrant further investigation. Although deconvolution techniques present an economical and efficient means for renal data analysis, the clinical utility cannot be fully realized until the signal-to-noise ratio of the data is improved

Analysis of a Gluonic Penguin Decay with the BaBar Detector

This thesis presents a branching fraction analysis of the neutral B meson decay channel B → ϕK0s where the K0s decays to π0π0. The decay is dominated by gluonic penguin transitions, which have been very important for the main program of BABAR: the search for physics beyond the Standard Model. The decay channel has been established and is included in the CP analysis, which is sensitive to new physics. The data set consists of 227 million BB̅ pairs recorded by the BABAR detector at the Stanford Linear Accelerator Center. Sophisticated analysis techniques have been applied primarily to suppress background from e+e- → quark/anti-quark reactions. The analysis of such rare decay channels with BABAR relies on the availability of a large set of computer simulated data. For that purpose a computer cluster has been built at the University of Tennessee as part of the distributed computing support work for BABAR. The design and performance of the cluster is a main subject of this thesis work

Explaining the Original Understanding of Lopez to the Framers: Or, The Framers Spoke Like Us, Didn\u27t They?

An important part of the Court’s rationale in Lopez, and other “new federalism” decisions, is a sense that they are returning to the original meaning of the Constitution. We are aware that there may be differences between the Framers’ intent and the original understanding of the meaning of the Constitution when it was adopted. The discussion here will not enter into the debate over the methods and propriety of originalism, nor is it necessary. What we do here is to focus narrowly on one aspect of Lopez’s connection with the Framing era, which is to consider whether there is semantic continuity between key words of the Lopez holding and words the Framers and Americans of their day would have used; or, in other words, to perform a kind of reverse textualism and see how the Framers would have understood Lopez. After examining the meaning of key words in the Lopez holding and what they meant in the eighteenth century, we conclude not only that neither the Framers nor any American of their day would have understood Lopezto have anything like the meaning intended by the Lopez majority, but because of changed meanings of language the Framers would likely have violently rejected the literal holding of Lopez. We conclude by considering what this repugnancy between the language of Lopez and the language of the Framers means for the originalism of Lopez, its overall intelligibility, and the regulation of commerce
