Prepared for U.S. Army Corps of Engineers 441 G.

This report discusses a new engineering software tool to be used in the design or evaluation of flexible approach walls founded on clustered pile groups and subjected to barge train impact events. This software tool, Impact_Deck, is used to perform a dynamic, time-domain analysis

More than 50% of the US Army Corps of Engineers locks and their approach walls have continued past their economic lifetimes. As these structures wear out, they must be retrofitted, replaced, or upgraded with a lock extension. Innovative designs must be considered for Corps hydraulic structures, particularly flexible approach walls, and new tools for evaluating these designs must be developed. The Computer- Aided Structural Engineering (CASE) computer program CPGA performs basic pile group analyses using Saul s method. It is intended to be a simple program to aid in the rapid pile group analysis/design of the Corps hydraulic structures that are founded on groups of piles. The analysis uses the stiffness method, with the pile cap assumed to be rigid and the piles assumed to be linearly elastic. Soil resistance to pile movement may be included. Probabilistic data generated during a reliability analysis of Corps hydraulic structures is formally used in risk and reliability engineering for major rehabilitation studies. Reliability studies deal with the demand on a system and the capacity of the system to respond to that demand. Both the demand and capacity can contain uncertainty, so the interaction of demand and capacity also will be uncertain. A reliability index can be determined for the uncertain interaction, and the probability of unsatisfactory performance can be determined from the reliability index. This report deals with the extension of CPGA to include the generation of probabilistic data and application of risk-based methods to the analysis of the Corps pile group-founded hydraulic structures. The software is named CPGA-R, with the R referring to the new reliability analysis capability. CPGA-R uses both Advanced Second Moment (ASM) and Importance Sampling Simulation reliability analyses techniques., The original document contains color images.

One type of flexible substructure used for new flexible approach wall structural system designs in the Corps is flexible pile groups. Simplified analysis procedures for flexible approach wall systems founded on groups of piles and subjected to barge train impact is discussed in this report. Pile bent groups of vertical piling and batter piling are investigated. A balance of energy design procedure is presented. This procedure assumes that all the kinetic energy (KE) of the approaching barge train (normal to the wall) is converted to potential energy (PE), or strain energy, through deformation of the flexible piling. A pushover analysis technique is used to establish the potential energy (PE) capacity and displacement capacity of individual pile groups accounting for the various pile failure mechanisms. The total stored energy (PE) of the approach wall system will be the sum of the stored energy of all the pile groups reacting to the barge impact. With three-dimensional (3-D) structural detailing of the impact deck (or beam), a model can be created where barge train impact loading may be shared by nearby supporting pile bents. The performance of this type of flexible approach wall system is also investigated., The original document contains color images.

Simplified analysis procedures for flexible approach wall systems founded on groups of piles and subjected to barge train impact is discussed in this report. Pile bent groups of vertical piling and batter piling are investigated. A “balance of energy” design procedure is presented. This procedure assumes that all the kinetic energy (KE) of the approaching barge train (normal to the wall) is converted to potential energy (PE), or strain energy, through deformation of the flexible piling.

To design simply-supported, flexible impact beams spanning between cells or bents for lock approach walls, a dynamic structural analysis of the beam under impact time-history loads for design- specific barge trains is required. At several locks, this flexible structural feature is the primary structural member resisting the glancing-blow impact event of a barge train as it aligns itself with a lock. This technical report describes an engineering methodology used to conduct this dynamic structural analysis and visualize the resulting deflections, moments, and shears. This engineering methodology is implemented with a PC-based FORTRAN program and visual modeler named Impact_Beam. The engineering formulation for Impact_Beam uses time-history force data that are scaled for design specific barge trains to perform a dynamic structural response analysis for either a single degree of freedom system or a modal timehistory analysis for the simply supported beam subjected to a impact load that is travelling along the beam. Time-history force data has been collected from the interpretation of the results from the 1997 full-scale barge train impact prototype experiments conducted at Old Lock and Dam 2 just north of Pittsburgh, PA, and of the 2008 full-scale barge train impact experiments conducted at Winfield Lock and Dam, Winfield, WV. This database of pulse time-history can be scaled for site specific design barge trains with approach angle and velocity using the companion software Impact_Force. It is also possible to use force time-histories from other impact simulation software (e.g., dBEAS). The engineering formulation for Impact_Beam is verified against the original Winfield experiments using modal time-history analysis and dBEAS simulations using single degree of freedom analysis., The original document contains color images.

An impact between a tow and the bullnose of a lock approach wall can result in the tow breaking up with loose barges moving out of control toward the lock or navigation dam with serious consequences. Project operations can be severely affected or even shut down. The loose barges can cause a high safety risk to personnel involved and if the navigation pool is lost or the lock is damaged, significant economic impacts may result. This Technical Report discusses the second stage of research into the development of a Deformable Bullnose Energy Absorbing System (BEAS) impact structure that would help reduce or prevent lashing failures and loose barges due to an impact between a tow and a lock approach wall bullnose. In simulations, the first improvement for limiting approach velocity to maintain barge integrity was achieved by the proper selection of lashing layout. The second improvement was achieved by the introduction of the Deformable BEAS. For a head-on collision between a three by five barge train at 3.3 feet per second and a rigid bullnose, barge train integrity is lost. For the same barge train, this report shows that the addition of an impact nosing with double stacked, soft base isolators for a Deformable BEAS extends the maintenance of barge train integrity to 4.5 feet per second. For a head-on collision between a three by four barge train at 3.0 feet per second and a rigid bullnose,barge train integrity is lost. For the same barge train, this report shows that the addition of the collapsible front arch to an impact nosing with double stacked, soft base isolators for a Deformable BEAS extends the maintenance of barge train integrity to 4.7 feet per second. These results imply that the addition of other innovative energy absorbing features could allow for even higher approach velocities., The original document contains color images.

To conduct a dynamic structural response analysis of flexible approach walls at Corps locks using structural dynamics engineering computer programs, a force time history is needed to represent the impact of a barge train with the approach wall. This technical report describes an engineering methodology used to create this pulse force time history normal to the wall. This engineering methodology is implemented with a PC-based FORTRAN program and visual modeler named Impact_Force. The engineering formulation for Impact_Force uses existing pulse data or synthetic pulse data and the impulse momentum principle to convert the linear momentum of a barge train into a pulse force time history acting normal to the approach wall. Included in this effort is the interpretation of the results from the 1997 full-scale barge train impact prototype experiments conducted at Old Lock and Dam 2 just north of Pittsburgh, PA, and of the 2008 full-scale barge train impact experiments conducted at Winfield Lock and Dam, Winfield, WV., The original document contains color images.

A technique is presented for rapidly producing unstructured finite element meshes in support of large-scale remote sensing simulations. These tetrahedral meshes typically have more than one million elements and more than 250 thousand nodes, and allow for arbitrary placement of objects into the domain. Open-source mesh generation packages are used in conjunction with a tetrahedra element smoothing operation to achieve the desired final meshes. Meshes can be reproduced in less than 30 minutes on a Cray XT3 architecture., The original document contains color images. All DTIC reproductions will be in black and white.

This research report describes the engineering formulation and corresponding software developed for the translational response of rockfounded retaining walls buttressed at their toe by a reinforced concrete slab to earthquake ground motions. The PC software CorpsWallSlip (sometimes referred to as CWSlip) was developed to perform an analysis of the permanent sliding displacement response for each proposed retaining wall section to either a user-specified earthquake acceleration time-history via a Complete Time-History Analysis or to user-specified peak ground earthquake response values via a Simplified Sliding Block Analysis. The resulting engineering methodology and corresponding software is applicable to a variety of retaining walls that are buttressed at their toe by a structural feature (e.g., navigation walls retaining earth, spillway chute walls, spillway discharge channel walls, approach channel walls to outlet works structures, highway and railway relocation retaining walls, and floodwall channels). CorpsWallSlip is particularly applicable to L-walls and T-walls (usually referred to as cantilever retaining walls). It may also be used to predict permanent seismically induced displacements on retaining walls without a toe restraint. Companion PC software, CorpsWallRotate, was developed to perform an analysis of permanent wall rotation. Both CorpsWallSlip and CorpsWallRotate software perform engineering calculations that help the engineer in assessment of the tendency for a retaining wall to slide or to rotate during earthquake shaking. Formal consideration of the permanent seismic wall displacement in the seismic design process for Corps-type retaining structures is given in Ebeling and Morrison (1992)., The original document contains color images. Prepared in collaboration with Science Applications International Corp.

Desmopressin [1-deamino-8-d-arginine vasopressin (DDAVP)] has been successfully used in the treatment of type 1 von Willebrand disease (VWD) and mild haemophilia A (MHA). Data suggest that DDAVP can increase factor XI (FXI) plasma levels and may represent an effective treatment for mild FXI deficiency. We assessed the DDAVP response of FXI coagulant activity (FXI:C), FXI antigen (FXI:Ag), factor V coagulant activity (FV:C), and factor X coagulant activity (FX:C) in 33 individuals with VWD or MHA. DDAVP did not produce a clinically significant increase in FXI:C, FXI:Ag, FX:C or FV:C in any patient. The mean +/- SD FXI:C pre-DDAVP (time 0) and at 1 h post-DDAVP was 90.7 (+/-22.9) U/dl and 92.1 (+/-20.9) U/dl, respectively. The mean (+/-SD) FXI:Ag at time 0 and 1 h was 92.2 (+/-20.1) U/dl and 89.9 (+/-21.3) U/dl, respectively. There was a small reduction at 1 h post-DDAVP in both FV:C, from 101.8 (+/-20.9) U/dl to 97.2 (+/-21.4) U/dl (P < 0.001), and FX:C from 103 (+/-19.5) U/dl to 98.8 (+/-18.7) U/dl (P < 0.001). No significant increase in FXI:C, FXI:Ag, FV:C or FX:C levels was seen at 4 h post-DDAVP. This study failed to demonstrate a clinically significant increase in the levels of FXI, FX or FV following administration of DDAVP.

Since its national debut in 1987, Fresh Air with Terry Gross has been a highly acclaimed and much adored weekday magazine among public radio listeners. Each week, nearly 4.8 million people turn to Peabody Award-winning host Terry Gross for insightful conversations with the leading voices in contemporary arts and issues. The renowned program reaches a global audience, with over 620 public radio stations broadcasting Fresh Air, and 3 million podcast downloads each week. Fresh Air has broken the mold of 'talk show' by weaving together superior journalism and intimate storytelling from modern-day intellectuals, politicians and artists alike. Through probing questions and careful research, Gross's interviews are lauded for revealing a fresh perspective on cultural icons and trends. Her thorough conversations are often complemented by commentary from well-known contributors. Fresh Air is produced at WHYY-FM in Philadelphia and broadcast nationally by NPR., (1.) Soul singer BARRY WHITE, the sweet-talking, deep-voiced performer who rhapsodized about love, died on July 4th. He was 58. The cause was kidney failure. His hits included "My First, My Last, My Everything," "Never Never Gonna Give Up," and "I'm Gonna Love You Just a Little More." Before he became a hit as a solo performer, WHITE put together the female vocal trio, Love Unlimited and founded the Love Unlimited Orchestra, a 40 piece ensemble to accompany himself and the trio. WHITE wrote his autobiography, "Barry White: Love Unlimited." (written with Marc Eliot, published by Broadway books in 1999).

The SOILSTRUCT-ALPHA for Personal Computers analysis package comprises three separate stages: the Visual Modeler, the SOILSTRUCT-ALPHA Finite Element Analysis Program, and the Visual Postprocessor. This report describes how the SOILSTRUCT-ALPHA Visual Modeler (i.e., a preprocessor) is used, applying it to the suggested work flow of a typical project as an example. This report is intended to serve as a user's guide and not as a reference manual defining each specific command. SOILSTRUCT-ALPHA is a special-purpose finite element program for two-dimensional, plane strain analysis of soil-structure interaction problems. SOILSTRUCT calculates displacements and stresses resulting from incremental construction, backfilling, excavation, dewatering, rising water table, and/or load application. Nonlinear, stress-path-dependent, stress-strain behavior of the backfill was approximated in the finite element analysis using the tangent modulus method. In the tangent modulus method, new values of tangent moduli are assigned to each soil element at each increment of loading (i.e., dewatering, lock construction, and backfilling) or unloading (i.e., excavation, rising water table). The modulus values assigned to each element are adjusted in accordance with their stresses to simulate nonlinear behavior. The Visual Modeler is designed to facilitate the development of a finite element mesh for SOILSTRUCT-ALPHA in a timely manner. The modeler comprises two parts, a computer-aided design tool for the actual creation and refinement of a mesh, including four-noded two-dimensional continua and interface elements, and a computer-aided design tool for the application of loads to the mesh and the creation of one-dimensional, two-noded bar elements. These tools expedite the creation and refinement of the often extensive input data to SOILSTRUCT-ALPHA., Original contains color plates: All DTIC reproductions will be in black and white.

Her thorough conversations are often complemented by commentary from well-known contributors. Fresh Air is produced at WHYY-FM in Philadelphia and broadcast nationally by NPR., INT. 1: Soul singer BARRY WHITE, the sweet-talking, deep-voiced performer who rhapsodizes about love. His hits include "My First, My Last, My Everything," "Never Never Gonna Give Up," and "I'm Gonna Love You Just a Little More." Before he became a hit as a solo performer, WHITE put together the female vocal trio, Love Unlimited and founded the Love Unlimited Orchestra, a 40 piece ensemble to accompany himself and the trio. WHITE has a new autobiography, "Barry White: Love Unlimited." (written with Marc Eliot, published by Broadway books). His new CD is "Barry White: Staying Power" (Private music). (THIS INTERVIEW CONTINUES INTO THE SECOND HALF OF THE SHOW).INT. 2: BARRY WHITE continued.REV. : Book critic MAUREEN CORRIGAN reviews the new novel "Headlong" (Henry Holt) by British author Michael Frayn.

This thesis is concerned with the means by which the state in Britain has attempted to influence the technological development of private industry in the period 1945-1979. Particular emphasis is laid on assessing the abilities of technology policy measures to promote innovation. With that objective, the innovation literature is selectively reviewed to draw up an analytical framework to evaluate the innovation content of policy (Chapter 2). Technology policy is taken to consist of the specific measures utilised by government and its agents that affect the technological behaviour of firms. The broad sweep of policy during the period under consideration is described in Chapter 3 which concentrates on elucidating its institutional structure and the activities of the bodies involved. The empirical core of the thesis consists of three parallel case studies of policy toward the computer, machine tool and textile machinery industries (Chapters 4-6). The studies provide detailed historical accounts of the development and composition of policy, relating it to its specific institutional and industrial contexts. Each reveals a different pattern and level of state intervention. The thesis concludes with a comparative review of the findings of the case studies within a discussion centred on the arguments presented in Chapter 2. Topics arising include the state's differential support for the range of activities involved in innovation, the location of state-funded R&D, the encouragement of supplier-user contact, and the difficulties raised in adoption and diffusion.
