Ship Maintenance Project: Phases II and III. Volume 3. Repair Management System for Critical Structural Details in Ships. (1997)

Abstract : This report presents the results of the second and third phases of the subject project of which phase one was first presented in our four volume set - SSC-386. These studies investigated the development of engineering technology that could lead to improvements in structural maintenance for new and existing tankers. These projects built further upon the work started in phase I specifically focusing on critical structural details and corrosion limits. The report has been divided into five volumes, each of which may stand alone. Volume one opens with a summary of all three phases by Professor Robert G. Bea, the coordinating investigator for the program, and follows with a report on corrosion limits for tankers. The second and fifth volumes look into evaluation of cracked critical structural details in tankers. The third volume presents theory and user instructions for software to manage repair of critical structural details. The fourth volume applies to fatigue classification of critical structural details. The software developed in the project will be available on the next Ship Structure Committee CD Rom release which is anticipated to be released in the next year.
Identifying and Correcting Mislabeled Training Instances (2007)

In order to form a good generalization from a set of training instances, a clean training dataset is important. Unfortunately, real world data is never as perfect as we would like it to be and can often suffered from corruptions. In this paper, a new approach is proposed to identify and correct mislabeled training instances. For a given instance, we employ a Bayesian classifier to evaluate the probabilities of the instance belonging to all considered class labels. Then information entropy calculated from the probability distributions is used to evaluate the typicality of the instance belonging to considered class labels. Finally, the instance with low entropy, but with error prediction result, would be identified as mislabeled instance. Experimental results indicate that our approach gains comparative or better performance than previous techniques.
In Situ Control of Oxygen Vacancies in TaO<sub><i>x</i></sub> Thin Films via Plasma-Enhanced Atomic Layer Deposition for Resistive Switching Memory Applications (2017)

The plasma-enhanced atomic layer deposition (PEALD) process using Ta(OC<sub>2</sub>H<sub>5</sub>)<sub>5</sub> as a Ta precursor and plasma-activated hydrogen as a reactant for the deposition of TaO<sub>x</sub> films with a controllable concentration of oxygen vacancies (V<sub>O</sub>) is reported herein. The V<sub>O</sub> concentration control was achieved by varying the hydrogen volume fraction of the hydrogen-argon mixture in the plasma, allowing the control of the leakage current density in the tantalum oxide films within the range of 5 orders of magnitude compared with the Ta<sub>2</sub>O<sub>5</sub> film grown via thermal ALD using the identical Ta precursor and H<sub>2</sub>O. Temperature-dependent current-voltage measurements combined with Poole-Frenkel emission modeling demonstrated that the bulk trap depth decreases with the increasing hydrogen volume fraction, which could be attributed to the increase of the V<sub>O</sub> concentration. The possible chemical change in the PEALD TaO<sub>x</sub> films grown under different hydrogen volume fractions was confirmed by the in situ X-ray photoelectron spectroscopy (XPS) measurements of the Ta 4f core and valence band spectra. The comparison of the XPS-measured nonstoichiometry and the secondary ion mass spectrometry analysis of the hydrogen content allowed this study to conclude that the nonstoichiometry is largely related to the formation of Ta-V<sub>O</sub> sites rather than of Ta-H sites. Such oxygen-deficient TaO<sub>x</sub> layers were studied for application as an oxygen-deficient layer in a resistance switching random access memory stack (Ta<sub>2</sub>O<sub>5</sub>/TaO<sub>x</sub>) where the actual switching occurred within the stoichiometric Ta<sub>2</sub>O<sub>5</sub> layer. The bilayer memory stack showed reliable resistance switching up to ∼10<sup>6</sup> switching cycles, whereas the single-layer Ta<sub>2</sub>O<sub>5</sub> memory showed only several hundred switching cycles.
Experimental control and model validation : a helicopter case study (2008)

Robust control has not been used as widely as it could because modelling tools have not advanced as far as analysis and synthesis tools. This becomes readily apparent when applying robust control theory to real problems. With this in mind, an experimental platform was designed and built to study the application of robust control. This platform consists of a real-time computer and a radio-controlled model helicopter mounted on a six degree-of-freedom stand. Experimental systems provide the opportunity not only to verify the applicability of new control theory but also to highlight potential deficiencies. Traditional system identification and control techniques were used to construct hover controllers for the model helicopter. These techniques are not suitable for the construction of robust models for a system of this complexity. In particular, there was no systematic way to augment nominal identified models with uncertainty suitable for the construction of robust controllers. To address this issue, frequency-domain model validation algorithms and software were developed. These algorithms provide a methodology for verifying the applicability and consistency between experimental data and robust models. Additionally, they provide a method whereby nominal model parameters can be tuned in a robust setting. This is the first set of software tools which provide this capability for general linear uncertain systems. Using these new software tools, a systematic design process was developed which incorporated frequency-domain model validation analysis, µ-analysis and µ-synthesis, simulation, and implementation. This design process proved to be a valuable new tool for constructing robust models and designing robust control systems. In particular, by applying this design process to the helicopter, the size of uncertainty in the robust model was substantially reduced without sacrificing the ability of the model to "cover" experimental data and the first controller implemented performed well. This was strikingly different from the results obtained when using standard robust control techniques, where several controllers destabilized the helicopter when implemented, even though they performed well under simulation. The model validation software and design process provide a consistent methodology and systematic framework which connects system identification, the construction of robust models, and controller synthesis with experimental data. For the first time the control engineer can compute measures on the validity of a robust model, with respect to all observed data on the actual physical system, which are directly related to the robustness measures resulting from µ-analysis and µ-synthesis.
The multidither principle in adaptive optics (1977)

Coherent optical adaptive techniques (COAT) offer promise for overcoming the deleterious effects of phase distortions experienced by optical beams propagating through distorting optics or via a turbulent and absorbing atmosphere. The theory of four classes of such systems, which employ similar multidither principles, is explored. Many modes of operating these systems are briefly reviewed and a detailed analysis of the most widely employed—a glint referencing system with sinusoidal dithers—is developed. A servo signal-to-noise analysis indicates how the optimum choice of dither magnitude depends on the system noise.
Synthesis of N-(2-[18F]fluoroethyl)-N′-methylthiourea: a hydrogen peroxide scavenger (1998)

N-(2-[18F]fluoroethyl)-N′-methylthiourea ([18F]FEMTU), a fluorine-18 labelled derivative of the hydrogen peroxide scavenger dimethlthiourea (DMTU), has been synthesized by reaction of 2-[18F]fluoroethylamine with methylisothiocyanate. 2-[18F]Fluoroethylamine was obtained in modest radiochemical yields (39±6%, mean±sd, n=5, decay corrected) by nucleophilic substitution with [18F]fluoride on N-[2-(p-toluenesulfonyloxy)ethyl]phthalimide followed by deprotection with hydrazine and distillation. The distilled 2-[18F]fluoroethylamine was trapped in CH2Cl2 and reacted with methyl-isothiocyanate to yield [18F]FEMTU that was purified by reversed phase HPLC. The total synthesis takes 150 min and provides [18F]FEMTU with a specific activity of 3.3±0.5 GBq/μmol (mean±sd, n=3) at end of synthesis, with an overall decay corrected radiochemical yield of 25±8% (mean±sd, n=5). © 1998 John Wiley & Sons, Ltd.
Development of privacy-preserving RFID authentication system using mobile devices (2011)

A mobile RFID system is a radio frequency identification technology that allows users to read the information on its tags. Systems that allow free reading of tags with mobile RFID reader devices represent a significant risk to individual privacy because unauthorized individuals may easily obtain personal information from the tags. In addition, the fixed ID values on tags can be used to track users in network segments. Although various solutions have previously been proposed to resolve this RFID privacy problem, most require numerous calculations to be performed on the tags. Therefore, these techniques require active tags with high-capacity embedded processors, which are expensive. In addition, it is not practical to apply these techniques to a mobile RFID system based on passive tags attached to devices because of not only the high price but also the bulkiness of the tags themselves. In this paper, we propose an efficient protocol for authentication, which allows transferring of the heavy calculations to the mobile reader devices, thus requiring only the resulting values to be stored on the tags. This study mainly focuses on improving the limitations of existing RFID authentication protocols, which usually assume active tags. The proposed protocol achieves the same security level and performance that can be obtained through active tags. To evaluate the performance of the proposed protocol, we implemented it using EPC Gen-2 tags, a smartphone, a UHF RF dongle, and a database. The proposed protocol meets various security requirements such as tag protection and location- and traffic-tracking prevention. The proposed protocol also meets other requirements such as lightweightness and the desired level of performance.
Treatment of Acute Posterior Uveitis in a Porcine Model by Injection of Triamcinolone Acetonide Into the Suprachoroidal Space Using Microneedles (2013)

Results from this study suggest that 0.2 mg and 2.0 mg of SCS TA was as effective in reducing inflammation as 2.0 mg IVT TA injection in a model of acute posterior segment inflammation. There were no adverse effects, increased IOP, or evidence of procedural or drug toxicity following injection of TA into the SCS in porcine eyes.
Generalized Compression Dictionary Distance as Universal Similarity Measure (2014)

We present a new similarity measure based on information theoretic measures which is superior than Normalized Compression Distance for clustering problems and inherits the useful properties of conditional Kolmogorov complexity. We show that Normalized Compression Dictionary Size and Normalized Compression Dictionary Entropy are computationally more efficient, as the need to perform the compression itself is eliminated. Also they scale linearly with exponential vector size growth and are content independent. We show that normalized compression dictionary distance is compressor independent, if limited to lossless compressors, which gives space for optimizations and implementation speed improvement for real-time and big data applications. The introduced measure is applicable for machine learning tasks of parameter-free unsupervised clustering, supervised learning such as classification and regression, feature selection, and is applicable for big data problems with order of magnitude speed increase.

A Study on the Relation between Record and Information Management and Knowledge Management from the Perspective of Knowledge Management : Focused on the Definition and Management Process (2005)

지식경영(Knowledge Management), 지적 자산, 디지털 지식자산관리 등 지시에 관한 개념은 오늘날 많은 조직에서 중요한 화두가 되고 있다. 특히 우리나라의 경우만 보더라도 '지식정보화 강국'을 표방하면서 지식경영과 기록관리를 주요시책으로 채택하고 있어 문헌정보학의 관점에서 이에 대한 이론적 기반과 Best Practice에 관한 연구가 시급하다. 그러나 지식경영을 비롯 지식에 관한 종래의 많은 연구는 경영학 분야에서 주되게 연구되었거나 문헌정보학 내에서도 지식에 관한 통합적 연구 기반은 매우 부족한 형편이어서 정보통신발달(ICTs)에 따른 지식 및 관련 시스템 간의 관련성. 협업 가능성에 관한 논의도 거의 이루어지지 않고 있다. 이에 본 연구에서는 특히 지식경영과 기록관리를 중심으로 지식의 범주, 관리방법 등을 비교 연구함으로써 지식에 관한 통합관리의 발전적 대안을 제시하고자 한다. 본 연구는 특히 향후 지식경영 렌 기록관리체제를 도입하고자 하는 공공기관에 이론적 논거가 될 것으로 판단한다. The various concepts of knowledge such as Knowledge Management(KM). Intellectual assets and digital knowledge asset management are currently important issues among many organizations. To the country like Korea that has professed Itself for a great power of knowledge Information and adopted KM and Record and Information Management (RIM) as the country's main polity, the study on the theoretical basis and best practices of KM and RIM from the perspective of Library & Information science is very urgent. However, many studies on knowledge including KM were mainly done at the business administrative field. and the consolidated study basis on knowledge even in the Library & Information Sciences was quite in deficiency, furthermore any discussion on knowledge, correlation among related systems and the possibilities of cooperation as the development of Information communication has not been done. Therefore, this study is to present the alternative plan of the consolidated management on knowledge through comparative analysis on the definition, main function and trend of KM & RIM. Especially, this study would be the theoretical basis to the public organizations that plan to introduce KM & RIM.
Chromatin Proteins Share Antigenic Determinants with Neurofilaments (1985)

Antigenic determinants common to distinct proteins may be unambiguously identified by the use of monoclonal antibodies. Some monoclonal antibodies to mammalian neurofilaments have recently been shown to cross-react with the neurofibrillary tangles found at high density in the brains of senile dements with Alzheimers disease (SDAT). Here, we show that these antibodies also cross-react with chromatin proteins, including the linker histones H1 and H1(0). Elevated levels of histone H1(0) have also been reported in SDAT brains.
Silicone materials for LED packaging (2006)

Silicone based materials have attracted considerable attention from light emitting diode (LED) manufacturers for use as encapsulants and lenses for many high brightness LED (HB LED) devices. Currently silicones function in two key roles in HB LED devices, (1) as protective lenses and (2) stress relieving encapsulants for wire bond protection. The key attributes of silicones that make them attractive as light path materials for high brightness HB LEDs include their high transparency in the UV-visible region, controlled refractive index (RI), stable thermo-mechanical properties, and tuneable modulus from soft gels to hard resins. This paper will describe recent developments in moldable silicone hard resin materials. Progress on cavity moldable and liquid injection moldable (LIM) silicone compositions for discreet components is described. Also, an example of liquid injection overmolding is presented.
Nitric Oxide-inducible Expression of Heme Oxygenase-1 in Human Cells (2000)

Expression of heme oxygenase-1 (HO-1) in mammalian cells contributes to resistance to various types of free radical damage. Nitric oxide (NO) induces HO-1 in many cell types, but the specific contribution of transcriptional or post-transcriptional effects to this induction have remained unresolved. Here we show that the extent of HO-1 mRNA expression in IMR-90 and HeLa cells depends on the rate of NO delivery, and that the induction occurs more slowly in HeLa than in human fibroblast (IMR-90) cells. We used a specific NO scavenger (2-(4-carboxylphenyl)-4,4,5,5-tetramethylimidazolin-1-oxyl 3-oxide) that completely prevented the inducible expression of HO-1 by NO, pointing to direct signaling action of NO in this induction. By inhibiting transcription during the NO exposure, we have confirmed that NO treatment activates a mechanism that stabilizes HO-1 mRNA. The increase in the HO-1 mRNA half-life in IMR-90 cells was directly correlated with increasing rates of NO release. We also show here that the stabilization of the HO-1 message does not require de novo protein synthesis. Collectively, these results show that stabilization of HO-1 mRNA can be finely tuned to the NO exposure, and that the effect in human fibroblasts is mediated by a pre-existing protein.
Lasers with super-Gaussian mirrors (1990)

A systematic theoretical and experimental investigation of unstable resonators with variable reflectivity mirrors of a super-Gaussian profile is presented. The validity of a geometrical optics formalism for an algebraic mode calculation is discussed in comparison to the diffraction theory. A new method for the calculation of the output energy by means of a closed-form relationship that accounts for the effects of the transverse mode profile on gain saturation is presented. Various dielectric super-Gaussian mirrors have been fabricated, characterized, and tested in a pulsed Nd:YAG laser. Super-Gaussian resonators can provide even higher output energies than those of traditional unstable resonators and with better beam-focusing properties.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optical angular-momentum transfer to trapped absorbing particles (1996)

Particle rotation resulting from the absorption of light carrying angular momentum has been measured. When absorbing CuO particles (1-5\ensuremath{\mu}m) were trapped in a focused ``donut'' laser beam, they rotated, due to the helical phase structure of the beam. Changing the polarization of the light from plane to circular caused the rotation frequency to increase or decrease, depending on the sense of the polarization with respect to the helicity of the beam. Rotation frequencies were obtained by Fourier analysis of amplitude fluctuations in the backscattered light from the particles. \textcopyright{} 1996 The American Physical Society.
Prospective Evaluation of Precision Multimodal Gallbladder Surgery Navigation (2017)

This high-tech protocol illustrates the multimodal imaging of biliary anatomy towards precision cholecystectomy. Those visualization techniques could complement to reduce the likelihood of biliary injuries (NCT01881399).
Thermal Fluctuations of a Single-Domain Particle (1963)

A statistical ensemble of particles, with moment orientations (θ, φ), can be represented by a surface density W (θ, φ, t) of points on the unit sphere. The corresponding surface density J satisfies a continuity equation ∂W/∂t=−∇·J. With no thermal agitation, J=WṀ/Ms, where M is the vector magnetization (| M | = const = Ms); its rate of change Ṁ is assumed to be given by Gilbert's equation. To include thermal agitation, we may add to J a diffusion term −k′∇W; this gives directly the ``Fokker-Planck'' equation of a previous, more laborious calculation. When ∂/∂φ=0, the equation simplifies and can be replaced by a minimization problem, susceptible to approximate treatment. In the case of a free-energy function with deep minima at θ=0 and π, such treatment leads again to a result derived previously by a method adapted from Kramers and valid when v(Vmax−Vmin)/kT is at least several times unity (v=particle volume, Vmax and Vmin=maximum and minimum free energy per unit volume, k=Boltzmann's constant, T=Kelvin temperature). When the minima are not deep, a different treatment is necessary; this leads to a formula valid when v(Vmax−Vmin)/kT&lt;&lt;1.
Ectromelia virus: the causative agent of mousepox (2005)

Ectromelia virus (ECTV) is an orthopoxvirus whose natural host is the mouse; it is related closely to Variola virus, the causative agent of smallpox, and Monkeypox virus, the cause of an emerging zoonosis. The recent sequencing of its genome, along with an effective animal model, makes ECTV an attractive model for the study of poxvirus pathogenesis, antiviral and vaccine testing and viral immune and inflammatory responses. This review discusses the pathogenesis of mousepox, modulation of the immune response by the virus and the cytokine and cellular components of the skin and systemic immune system that are critical to recovery from infection.
Hardware algorithms for nonnumeric computation (1978)

This paper is concerned with the design of hardware algorithms for nonnumeric computation. The subset of nonnumeric operations considered is derived from string processing languages such as SNOBOL or high-level data base languages used in data base management architectures. It is shown that cellular hardware can be designed to perform these operations on-line while the data is accessed from a rotating secondary storage medium. Being uniformly structured, the hardware could be implemented using LSI technology yielding an estimated pattern matching rate of about 100 million characters/sec. The proposed nonnumeric processor will find applications in the environment of parallel (or associative) data base management architecture, processing of large unstructured textual files, as a stand-alone microprocessor in digital communications which need simple search and update operations, or as a nonnumeric CPU that can be used along with the conventional CPU to expedite string processing operations.
A review of thermo-stimulated current (1993)

Various areas of application of thermo-stimulated current (TSC) spectroscopy, used for studying insulating materials, are reviewed. The characteristics of this technique are compared with those of the other thermally stimulated spectroscopies. The origins of TSC are briefly cited. Examples of the identification of TSC peaks with ionic or molecular movements (inorganic or organic materials) are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
