Abstract:
Abstract. Gross primary production (GPP), separated from flux tower measurements of net ecosystem exchange (NEE) of CO2, is used increasingly to validate process-based simulators and remote sensing-derived estimates of simulated GPP at various time steps. Proper validation should include the uncertainty associated with this separation at different time steps. This can be achieved by using a Bayesian framework. In this study, we estimated the uncertainty in GPP at half hourly time steps. We used a non-rectangular hyperbola (NRH) model to separate GPP from flux tower measurements of NEE at the S

Abstract:
The effect of temperature dependent thermal conductivity on the performance of an asymmetrically heated extended surface which is commonly encountered in compact heat exchangers is studied both analytically and numerically. The surface is assumed to extend between two primary surfaces at different temperatures and to operate in a convective environment. The nonlinear differential equation governing the thermal performance of the extended surface is solved by carrying out a perturbation analysis in which the perturbation parameter is the dimensionless measure of thermal conductivity variation w

Abstract:
Abstract The contact impact response has been investigated as a nondestructive testing (NDT) parameter for identifying localized defects and damage in composite laminates, and the corresponding NDT method is known as the Acoustic Impact Technique (AIT). Theoretical formulation of the influence of defects on the contact impact response is the central focus of the present work. This impact method of nondestructive testing primarily involves applying a low velocity mechanical impact to the test specimen and evaluating the resulting localized acoustic response.

Abstract:
This paper demonstrates an approach for predicting and optimizing energy consumption in skid-steer mobile robots (SSMRs) conducting manufacturing tasks. This work is unique in that it considers the energy associated with real-time predictions of slipping in the SSMR and further considers a specific application in which the SSMR is operating in an inverted (climbing) configuration on metal surfaces with homogeneous properties. The approach is based on a dynamic model that provides estimates of SSMR slipping motion during simulation. The model is used to estimate the underlying components of ene

The Old River Control Complex (ORCC) consists of the Low Sill, Auxiliary, and Overbank structures as features of the Old River Control Structure (ORCS) and the privately owned hydro-electric power plant. Operations of the ORCC manage the hydrologic connectivity between the Mississippi River and the Atchafalaya River/Red River systems. The morphology of the Old, the Mississippi, the Atchafalaya, and the Red Rivers (OMAR) has been influenced by the flow distribution at the ORCC, as well as the accompanying bed sediments.

Abstract:
Modeling of actual and hypothetical compressor station facilities concluded increasing reciprocating engine stack height as one potential mitigation measure to reduce modeled impacts below the primary 1-hour NO2 National Ambient Air Quality Standards (NAAQS). Increasing stack heights to between 50-75 feet appears to offer considerable relief based on typical facility configurations (e.g., compressor house height, stack parameters). This white paper discusses potential stack design criteria to be considered when increasing existing exhaust stack heights or planning considerations for new units.

Abstract:
The objective of this program was to establish the feasibility of using nondestructive evaluation (NDE) techniques to measure on-site the yield strength of the steel used in gas pipelines. The need for this capability exists primarily because of the loss of construction records for many pipelines, which would document the grade of steel used to construct the pipeline. Without this information, pipelines must be operated at conservative pressures to minimize the chances for failure and to comply with 49 CFR part 192 of the federal requirements.

Abstract:
A partitioning inter-well tracer test (PITT) determines the residual (or even remaining) oil saturation (SOR) in the flooded region between well-pairs. This type of tracer test can be used to identify improved oil recovery (IOR) targets, evaluate IOR projects, evaluate enhanced oil recovery (EOR) methods, and improve reservoir description for efficient hydrocarbon production. Thus, the main objective of the work with inter-well oil/water partitioning tracers developed within the framework of the IOR Centre is to provide tools and methodologies to improve reservoir description for efficient man

Abstract:
Seismic ground failure potential from liquefaction is generally undertaken in three steps. First, a susceptibility evaluation determines if the soil in a particular layer is in a condition where liquefaction triggering could potentially occur. This is followed by a triggering evaluation to estimate the likelihood of triggering given anticipated seismic demands, environmental conditions pertaining to the soil layer (e.g., its depth relative to the ground water table), and the soil state. For soils where triggering can be anticipated, the final step involves assessments of the potential for grou

Abstract:
With the proliferation of Free Trade Agreements (FTAs) over the past decade, demand for quantitative analysis of their likely impacts has surged. The main quantitative tool for performing such analysis is Computable General Equilibrium (CGE) modeling. Yet these models have been widely criticized for performing poorly (Kehoe, 2002) and having weak econometric foundations (McKitrick, 1998; Jorgenson, 1984). FTA results have been shown to be particularly sensitive to the trade elasticities, with small trade elasticities generating large terms of trade effects and relatively modest efficiency gain
