Abstract:
Objective – To explore how undergraduate students interpret Library of Congress call numbers when trying to locate books. 
 
 Design – Multiple case study.
 
 Setting – A public, residential university in Illinois, United States of America.
 
 Subjects – 11 undergraduate students (10 upper division, 1 freshman; no transfer students included).
 
 Methods – A qualitative approach was adopted, with a multiple case study design used to facilitate the collection of data from several sources. Students were recruited for the study via convenience and snowball sampling. Participants who volunteered were interviewed and requested to complete a task that required them to organize eight call numbers written on index cards in the correct order. Interviewees were also asked about any instruction they had received on interpreting call numbers, and their experiences locating materials in other libraries and bookstores. Responses were then coded using colours to identify common themes.
 
 Main Results – The study reported that there was little correlation between the students’ own estimation of their ability to locate materials and their actual performance in the index card test. Five students who reported that they could find materials 75-100% of the time performed poorly in the test. Of the 11 participants, only 4 ordered the cards correctly, and in 1 such case this was by fortune rather than correct reasoning. Of these, three self-reported a high level of confidence in their ability to locate material, whilst one reported that he could only find the material he was looking for approximately half of the time. Of the seven students who incorrectly ordered the cards, no two students placed their cards in the same order, indicative that there is no clear pattern in how students misinterpret the numbers. During the interview process, five students stated that they experienced more difficulty locating books in bookstores compared with the library.
 
 Conclusion – Based on the findings of the study, the authors recommend several interventions which could help students to locate material within the library, namely through improved signage in shelving areas including the listing of subjects and colour-coding, as well as integrating training on understanding call numbers into subject-based instruction. The possibility of using online directional aids such as QR codes and electronic floor maps is also suggested as a strategy to help orient students.

Abstract:
This paper offers an overview of the Library of Congress Geography and Map Division and its efforts to digitise the collection. The number of hard copy maps is huge: over 5.5 million, most of them un-catalogued. New maps continue to be added to the collection, some in new, digital formats. The Library of Congress has been in the forefront of developing digital collections and providing digital access to its collections via the Internet. The Library's American Memory collection is described here, from its origins in the 1980s to its current format. American Memory's access to the Geography and Map collections is profiled, with features of the digital collection presented in detail. American Memory is constantly undergoing revision. The Geography and Map division currently features collections highlighting the American Civil War, Liberia, the Revolutionary war, early railroad maps, the Louisiana Purchase, and U.S. National Parks. The wealth of information contained in the map collection makes these digitisation efforts worthwhile even though only a small percentage of the total items can be posted online.

Abstract:
Using research from the Lyndon Johnson Presidential Library, FRUS, and the Congressional Record, the first chapter explores U.S.-Israel relations during Lyndon Johnson’s presidency. In 1967, provocative moves made by Egyptian President Gamal Abdel Nasser and an Israeli first strike plunged the region into war. Legislators took to the House and Senate floors to proclaim the essence of the special relationship—an unwavering American commitment to ensure Israel’s survival. In the aftermath of the war, the Johnson administration decided to abandon existing U.S. policy regarding territorial integrity in the Middle East and support Israeli occupation of Arab lands in order to pressure Arab states to finally recognize Israel and make peace with it. The Johnson administration, like the administrations before it, could not solve the riddle of Arab-Israeli conflict and regarded the war as an opportunity to pursue a different path. The decisions to not push Israel out of the territories and to increase weapons sales to Israel were both justified by the American commitment to Israel’s survival.

Abstract:
Currently, agile methods are replacing traditional process-based methods in the software industry. However, process-based software development still matters because of its degree of reusability in new projects. Some problems arise when Knowledge Management (KM) is not correctly aligned with processes, such as lack of productivity and process improvement. In this chapter, the authors present a case study of applying two proposals of process libraries in an agile software development division. The researchers and the software development division worked with a Kanban dashboard, eXtremme Programming (XP), and SCRUM practices, adapted to Process Assets Library (PAL) and to Process Practice Library (PPL) in three software projects in order to find experiences of tacit and explicit knowledge that have an impact on process improvement and productivity. Under results and discussion, the authors present the good and bad practices.

Abstract:
One of the most important tasks of a librarian is the assignment of appropriate subject(s) to a resource within a library’s collection. The subjects usually belong to a controlled vocabulary that is specifically designed for such a task. The most widely adopted controlled vocabulary across libraries around the world is the Library of Congress Subject Headings (LCSH). However, there seems to be a shifting from traditional LCSH to modern thesauri. In this paper, a methodology is proposed, capable of incorporating thesauri into existing LCSH-based Information Retrieval–IR systems. In order to achieve this, a mapping methodology is proposed capable of providing a common structure consisting of terms belonging to LCSH and/or a thesaurus. The structure is modeled as a Simple Knowledge Organization System (SKOS) ontology, which can be employed by appropriate subject-based IR systems. As a proof of concept, the proposed methodology is applied to the DSpace-based University of Piraeus digital library.

Abstract:
Late in 1970, President Nixon proposed and Congress approved creation of the Environmental Protection Agency (EPA), in the process transferring the Pesticide Regulation Division from USDA to EPA. For pesticide regulation, this was no minor matter. The transfer was from USDA, an agency that primarily protected pesticide manufacturers and promoted their products, to EPA, an agency that was directly charged with protecting the environment. That was to make a large difference in how the DDT issue would be resolved. The first administrator of EPA was William D. Ruckelshaus, an attorney with a sterling record of public service in government. The other major item was the decision on DDT from the DC Court of Appeals. On January 7, 1971, the court ordered Ruckelshaus to immediately cancel all registrations of DDT and to determine whether DDT was “an imminent hazard to the public” and therefore should be suspended. The court was clearly annoyed by USDA’s failure to give adequate reasons for not suspending, so “it will be necessary to remand the case once more, for a fresh determination” of the matter of suspension. The court had taken away the discretion usually afforded a federal agency and ordered it to take action. This was an unprecedented decision. EPA had only been created on December 2, 1970; Ruckelshaus barely had time to find his telephone before this court order landed on his desk as his first order of business. Perhaps the most important part of this decision was that EDF survived USDA’s motions to throw our case out of court. The standing for citizens to sue the government, previously unavailable, had now been established by this precedent-setting decision. This was the firm beginning of what we now call “environmental law.” But you should not take the legal conclusion of a lowly scientist (me). Instead, here are the words of Joseph L. Sax, a professor of law at the University of Michigan Law School, from his September 30, 1973, letter in support of EDF’s application for the Tyler Ecology Award (we did not get it).

Abstract:
The third chapter, based on research from the Richard Nixon Presidential Library, FRUS, and the Congressional Record, explores congressional reactions to Nixon’s request for $2.2 billion in emergency military aid for Israel, as well as U.S. efforts to restart the peace process. Despite efforts by Fulbright and several other legislators, along with the Nixon administration’s lack of effort to justify such a massive aid package, Congress passed the emergency aid bill in full. Legislators successfully argued that Israel needed the immense amount of aid in order to feel strong enough to take risks in peace negotiations. But by May 1974, fearful that Israel felt too strong, the Nixon administration started to threaten to cut off all military aid to soften Israel’s position in peace negotiations. The fall of Nixon due to Watergate sapped the power of the White House at precisely the moment when a strong president was needed to advance such an ambitious program of U.S. peace diplomacy. Also important, Kissinger had to work against pro-Israel elements that sought to scuttle his gradual approach to a comprehensive peace.

"Both opponents and proponents of food irradiation have been sources of misinformation or valid information presented in a misleading way (20). As described by a leading British consumer representative: “ The battle to get irradiation of food accepted as a beneficial food processing technique has been waged for some 30 years. It is an interesting case of warring factions glaring at each other across a gulf of incomprehension” ( ). In this book an attempt will be made to provide factual data as a basis for a more rational approach to these controversies. The seminar jointly held by IOCU (International Organization of Consumer Unions) and ICGFI (International Con­ sultative Group on Food Irradiation) in 1993 (22) has raised hopes that this gulf of incomprehension can be narrowed, perhaps even closed. There is voluminous scientific literature on food irradiation, but it is not easy to come by because contributions have come from so many disciplines. Relevant reports have been published in journals of food technology, nutrition, microbiol­ ogy, analytical chemistry, food chemistry, radiation chemistry, radiation physics, toxicology, health physics, and other fields. There is only one scientific journal devoted exclusively to food irradiation research: Shokuhin-Shosha (Food Irradia­ tion, Japan), published by the Japanese Research Association for Food Irradiation since 1965; articles are in Japanese, with English abstracts. In order to facilitate access to this literature a computerized irradiation information database called IRREFCO (Irradiation Reference Collection) has been installed at the National Agricultural Library in the United States. It is initially aimed at making available the research contract reports generated in programs sponsored by the U. S. Army and U. S. Atomic Energy Commission in the 1950s and 1960s. Those reports are not accessible through ordinary library services. A selected annotated bibliogra­ phy is offered since 1993 (23). A bibliography on food irradiation has been prepared since 1955 by the Federal Research Center for Nutrition, Karlsruhe, Germany; it now contains over 10,000 documents. The whole database is pro­ cessed and stored on computer, and is also available in printed form. In recent years one issue of the printed bibliography has been published annually, each with 300-600 references (24). In the following chapters only a small fraction of these documents can be mentioned. The author endeavors to quote primarily those studies that will guide the reader to key issues, to review articles, and to other works showing a path to the remaining literature. Useful documentation of developments in food irradiation research can be found in three newsletters. Food Irradiation Quarterly International Newsletter (Saclay) was published in English and French by the European Information Center for Food Irradiation, Saclay, France, from 1960 to 1971. The International Project in the Field of Food Irradiation issued Food Irradiation Information (Karlsruhe) from 1972 until 1982. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, has Published Food Irradiation Newsletter (Vienna) since 1976."

Abstract:
A three-dimensional numerical simulation is performed to study a heaving airfoil with an immersed boundary method. Flow around a heaving airfoil has been widely investigated by using two-dimensional simulation; while few previous works discussed the physical behavior of flow over heaving airfoils with three-dimensional effects. The purpose of this study is to identify characteristic features of flow over heaving airfoils in three-dimensional simulation in comparison with those in two-dimensional cases. In particular, the vortical wakes downstream of the heaving ellipsoid wing is characterized by a reversed-Karman-vortex-street-like structure, which is a reduced reversed-Karman vortex street. The implication of this characteristic is found to be the reduced leading-edge vortex on the 3D wing. In order to fulfill the computational requirement, a parallel implementation of the immersed boundary method (Zhang & Zheng [1]) is presented. The pressure Poisson equation is solved with the assistance of a portable scientific parallel computational library (PETSc). This code is validated with a case of flow over a stationary sphere. The parallel performance is also demonstrated.

Abstract:
The Engineering Pathway (EP) digital library (www.engineeringpathway.com) strives to provide quality educational resources for learners of all age levels. ABET Engineering Criteria has been the driving force behind modern engineering education reform since its introduction at the turn of the century. In order to help engineering educators and administrators meet the challenges of developing and teaching a learning outcomes-focused curriculum, EP is linking existing resources to appropriate ABET criteria. This paper summarizes the research behind using our ABET alignment process where computational linguistics and information retrieval tools are used to augment the ABET alignment process. Experts then review these recommendations and make corrections where needed. By taking this approach, we not only shorten the time to align existing learning resources; but also improve the scalability by aligning new resources as they are being submitted. The technologies can also be applied to the development of thesauri and recommender systems that can be tailored to individual faculty needs.

Abstract:
Fragmentation of molten metal droplets is an important process in steam explosions caused by melt-coolant interactions. Ciccarelli and Frost (1994) found the formation of melt jets (or spikes) in hot melt drops immersed in water. In order to gain insight into this mechanism, they carried out experiments where melt jets were formed in a stratified water/liquid metal system with local generation of high-pressure vapor at the interface. This paper is dedicated to investigating how melt jets are formed in this mechanism when a stratified water/liquid metal system is analyzed. Also, a study of the most significant parameters in this process is performed. A 2D computational fluid dynamics (CFD) simulation is carried out using ANSYS Fluent software to study these phenomena by having water above hot liquid metal, a vapor film in between and a pressure pulse in the vapor film. The results show that the larger the pressure or density, the greater the melt jet length. In order to confirm this, deep neural network algorithm created by TensorFlow library was implemented to facilitate the understanding of the studied phenomena. The formation of melt jets observed in Ciccarelli and Frost’s experiments is also observed in current simulation.

Abstract:
The virtual reality is a multi-functional, interactive and immersible technology. As an advanced engineering design technology, the virtual reality technology (VRT) has been widely used in large mining machinery design and manufacturing. The system is based on DIVISION Mockup2000i2 software. Virtual prototype of the Tunnel Boring Machine (TBM) is studied in this paper. In addition, the movement simulation of TBM is completed in DIVISION Mockup2000i2. Firstly, CATIA software is adopted to build the parts of TBM. The TBM is assembled in CATIA too. Secondly, the THEOREM software is applied to convert the assembled model of TBM to another format which can be identified in DIVISION MOCKUP2000i2 software. In order to make the TBM image living, life-like and easy to browse, the light of surface, virtual materials and landmark scenes are set up in DIVISION MOCKUP2000i2 software environment. All motion parameters of the parts are defined before the simulation. Then, the virtual movement simulation of TBM components is analyzed with the behaviors property of MOCKUP. The virtual movement of cutting wheel, screw conveyor machinery and the door of mud out are studied. The virtual movement of segments and segment erector machine are completed by setting up virtual parts and virtual event. Five segments are fixed accurately in a cycle. The relations and interference of the parts movement are examined simultaneity. The hotkey is defined before the simulation, which can trigger the continuous implementation of virtual motion. In addition, a virtual voice is used to enhance the performance of movement simulation. The virtual prototype of TBM being set up and simulated will have positive significance for design inspection, structural analysis and product introduction without TBM physical prototype being manufactured.

In ASME 2006 Internal Combustion Engine Division Fall Technical Conference. ASMEDC, 2006. http://dx.doi.org/10.1115/icef2006-1506.

Full text
Abstract:
In order to comply with current emissions regulations, a detailed analysis of the combustion and emission formation processes in the Diesel engines accounting for the effect of the main operating parameters is required. The present study is based both on 0D and 3D numerical simulations by compiling 0D chemical kinetics calculations for Diesel oil surrogate combustion and emission (soot, NOx) formation mechanisms to construct a φ-T (equivalence ratio - temperature) parametric map. In this map, the regions of emissions formation are depicted defining a possible optimal path between the regions by placing on the same map the engine operation conditions represented by the computational cells, whose parameters (equivalence ratio and temperature) are calculated by means of 3D engine modelling. Unlike previous approaches based on static parametric φ-T maps to analyze different combustion regimes and emission formations in Diesel engines, the present paper focuses on a construction of dynamic φ-T maps, in which the pressures and the elapsed times were taken in compliance with those calculated in the 3D engine simulations. The 0D chemical kinetics calculations have been performed by the SENKIN code of the Chemkin-2 library. In-cylinder conditions represented by computational cells with known φ and T are predicted using KIVA-3V code. When cells are plotted on the map, they identify the trajectories helping to navigate between the emissions regions by varying hardware and injection parameters. Sub-models of the KIVA-3V, rel. 2 code has been modified including spray atomization, droplet collision and evaporation, accounting for multi-component fuel vapor coupled with the improved versions of the chemistry/turbulence interaction model and new formulation of the combustion kinetics for the diesel oil surrogate (consisting in 70 species participating in 310 reactions). Simulations were performed for the HSDI 1.300 Fiat Diesel engine at optimized engine operating conditions and pilot injections. Finally, numerical results are compared with the experimental data on in-cylinder pressure, Rate of Heat Release, RoHR, and selected species distributions.

Full text
Abstract:
Because they have the potential for ultra low NOx emissions and high efficiency, Homogeneous Charge Compression Ignition (HCCI) engines have the potential to develop a significant niche. However, a narrow operating range, (bracketed by severe knock and misfire problems), presents a formidable obstacle to developing usable HCCI combustion systems. HCCI combustion is influenced by a complex array of operating variables including fuel octane quality, intake preheating temperature, compression ratio, equivalence ratio, exhaust gas recirculation and engine component temperature. These variables affect the two critical combustion parameters: ignition timing and combustion duration. If these two parameters can be controlled by appropriate settings of the operating variables, a good HCCI combustion scheme could be achieved. Therefore, the theoretical prediction of these two combustion parameters as a function of the key operating variables is necessary for development of HCCI combustion. This paper describes a stand-alone, single-zone and multi-zone combustion model which have been developed for the specific purpose of investigating HCCI combustion control. In the multi-zone model, temperature and composition in each zone were adjusted in order to study the effect of in-homogeneity which is critical to understanding ignition timing and combustion duration in real HCCI engines. The models simulated HCCI combustion using two fuels: hydrogen, (11 species, 23 reactions- from CHEMKIN library), and natural gas, (53 species, 325 reactions- from GRI mech). The capabilities of the two models to predict ignition timing, combustion duration and peak pressure were verified against experimental and simulation results of Fiveland et al [2, 11]. The models were then used to study the effect of different in-homogeneity levels of equivalence ratio, intake temperature and residual fraction. The single zone model could only predict ignition timing while the multi-zone model shows the capability to mimic realistic HCCI combustion phenomena. The study showed that some degree of in-homogeneity is critical to predicting performance of the homogeneous charge compression ignition engine. Further, stratification of equivalence ratio was relatively ineffective at changing combustion while stratification of mixture temperature was very effective. Stratification of the residual fraction proved to be the most promising method of controlling combustion parameters and the mechanism was primarily thermal.

Abstract:
When coiling a special-type spring in CNC coiler, the setup jobs of the coiler, including the type selection and position decision of various forming tools, cam layout, angle calculation of camshaft, are achieved by manual work using a trial-and-error method. This method seriously affects the spring production efficiency. In order to solve this problem, the coiling process planning system for spring based on CBR (case based reasoning) is developed in this paper. The system mainly comprises a case library that holds the details of coiling process plan. Similar cases are retrieved and adapted when a new spring is manufactured. The process of finding the most similar case is divided into three stages. Some key technologies of the system, including the information model of the spring coiling process and the structure of the case library, are also revealed in this paper. The result indicates that this system reduces the setup time and enhances the production efficiency of spring.

Abstract:
Advanced composite materials such as Carbon Fiber Reinforced Plastics (CFRP) are being applied to many aircraft structures in order to improve performance and reduce weight. Most composites have strong, stiff fibers in a matrix which is weaker and less stiff. However, aircraft wings can break due to Fluid-Structure Interaction (FSI) oscillations or material fatigue. This paper focuses on the analysis of a non-linear fluid-structure interaction problem and its solution in the finite element software package DOpElib: the deal.II based optimization library. The principal aim of this research is to explore and understand the behaviour of the fluid-structure interaction during the impact of a deformable material (e.g. an aircraft wing) on air. Here we briefly describe the analysis of incompressible Navier-Stokes and Elastodynamic equations in the arbitrary Lagrangian-Eulerian (ALE) frameworks in order to numerically simulate the FSI effect on a double wedge airfoil. Since analytical solutions are only available in special cases, the equation needs to be solved by numerical methods. This coupled problem is defined in a monolithic framework and fractional-step-θ time stepping scheme are implemented. Spatial discretization is based on a Galerkin finite element scheme. The non-linear system is solved by a Newton method. The implementation using the software library package DOpElib and deal.II serves for the computation of different fluid-structure configurations.

Abstract:
The main objective of the current work is to utilize Lattice Boltzmann Method (LBM) for simulating buoyancy-driven flow considering the hybrid thermal lattice Boltzmann equation (HTLBE). After deriving the required formulations, they are validated against a wide range of Rayleigh numbers in buoyancy-driven square cavity problem. The performance of the method is investigated on parallel machines using Message Passing Interface (MPI) library and implementing domain decomposition technique to solve problems with large order of computations. The achieved results show that the code is highly efficient to solve large scale problems with excellent speedup.
