Louisiana is severely affected by HIV/AIDS, ranking fifth in AIDS rates the USA. The Public Health Information Exchange (LaPHIE) a novel, secure bi-directional public health information exchange, linking statewide surveillance data with electronic medical record data. LaPHIE alerts providers when individuals HIV/AIDS who have not received HIV care for >12 months are seen at any ambulatory or inpatient facility an integrated delivery network. Between 2/1/2009 and 1/31/2011, 488 identified 345...
Although relatively recent in information systems design, the prototyping technique has a long tradition developing engineering systems. An system is defined as any artificial that performs actions to achieve desired transformation of objects undergoing change state. We will review application and experience with design relate these development systems. Drawing on strong similarities between processes results identification number different types prototypes can be used for variety...
This paper describes the development of tools to support better scheduling and sequencing barge tows on a congested portion Upper Mississippi River. Our study section covers 100 miles includes five 600-foot long locks that handle commercial up 1200 feet long. Due varying nature traffic lockage times (especially need split pass through smaller locks), queues may form at locks. provides an overview our research, including evaluation lock management policies, detailed multi-lock simulation...
A series of five locks form a transportation bottleneck in the upper Mississippi River navigation system. With optimizing models, statistical modeling and computer simulation, authors explore effects alternative scheduling regimes infrastructure changes to improve performance an inland waterway In this paper, show value triangulating integrating analysis with different research paradigms order strategies for improving major
Abstract Statistical texts differ in the ways they test significance of coefficients lower-order terms polynomial regression models. One reason for this difference is probably concern some authors that t ratios may change as a result linear scale transformations independent variables. Empiricists generally report tests these and attempt to interpret their meanings. This paper succinctly demonstrates how models affect statistical individual parameters.
This paper demonstrates problems in allocating inter-station inventory capacities unpaced production lines with heteroscedastic processing times. Simulations were performed to show the effects of total work-in-process capacity, relative allocations and pattern time variances upon rate, work station idle times complete a product. Trade offs among three performance measures observed deficiencies intuitive strategies for redesigning deduced.
Managing credit risk in financial institutions requires the ability to forecast aggregate losses on existing loans, predict length of time that loans will be books before prepayment or default, analyze expected performance particular segments portfolio, and project payment patterns new loans. Described this paper are tools created for these functions a large California institution. A forecasting model with Markovian structure nonstationary transition probabilities is used life mortgage....
We address the problem of estimating retail business potential at alternative sites, with concern for assessing performance relative to in existing markets and identifying best sites expansion into new markets. At question is utility information typically used formal patronage models, comparison additional considered important by executives. Relevant data are gathered from secondary sources intensive in-store surveys conducted produce a portfolio about neighbourhood demographics, store...
We describe a discrete-event simulation model used to investigate the impact of alternative decision rules for operations in congested section Upper Mississippi River navigation system. The accommodates commercial vessels with different barge-tow configurations and recreational vessels. Activities vary by time year, day week day. reveal potential benefits priority dispatching show their differential on tow configurations.
This paper proposes two new particle filters, namely, the auxiliary extended Kalman filter (AEKPF) and unscented (AUKPF). The theory governing newly proposed filtering techniques is developed algorithms are described contrasted. Next, a series of tests presented in which filters compared against (EKF), (UKF), several existing filters. test results from simulations with synthetic mathematical models that incorporate elements nonlinear, non-stationary, stochastic. Performance for various...
The Mississippi River is an important waterway in national and global supply chains, especially for agricultural commodities. tools available managing traffic congestion on the Upper (UMR) include operational policies such as sequencing vessels at locks, tactical decisions using helper boats to speed lockages, strategic constructing new larger locks. We describe use of our detailed multi-lock discrete event simulation model evaluate operational, mitigation measures UMR. With a focus policy...
