3D visualization of simulated construction operations (2000)

Significant advances have been made in the field of construction process modeling. However, no convenient graphical support tools exist that can depict the modeled operations in 3D. This results in the black box effect being experienced by many simulation output analysts who have reservations about the credibility of the analysis based solely on the text and chart based output provided by most simulation software. The process visualization/animation tools currently available commercially are restricted to two dimensions (e.g. PROOF™), inherently lacking in the real world 3D capabilities that are indispensable for the realistic visualization of many construction operations. This paper describes on-going research at Virginia Tech that focuses on the development of a general-purpose, 3D text file-driven visualization system. This system enables visualization of both the construction processes and the evolving products in 3D. The input to the program is an ASCII text file consisting of sequential animation commands. This file can be generated automatically by a variety of simulation software capable of writing formatted text during simulation runs. Due to the flexibility of the command set and the independence of the tool from any particular simulation modeling software, the system has numerous potential applications in fields other than construction, such as in the manufacturing and service industries.

Hormone Amyloids in Sickness and in Health (2013)

Amyloids are highly ordered cross-β-sheet containing protein aggregates associated with several dozens diseases including Alzheimer's, Creutzfeldt-Jakob and Parkinson's disease, and are also associated with functional states such as hormone storage in secretory granules. In the protein fold universe unique cross-β-sheet entity composed of an intermolecular motif repetitive in nature is key for the multiple properties of amyloids. The repeating motifs can translate a rather nonspecific interaction into a specific one through cooperativity and/or avidity, while the cross-β-sheet entity can grow by recruitment of the corresponding amyloid peptide/proteins. Because of these properties, activities of amyloids including peptide storage, template assistant, loss of function, gain of function, generation of toxicity, membrane binding, infectivity, and so on are manifold. In this review, we will discuss the possible role of the amyloid entity in the storage of hormones in secretory granules of endocrine cells as well as the disease association of hormone amyloids with particular focus on diabetes insipidus. Thus, the structure–activity relationship of hormone amyloids in health and disease will be described.
A Novel Method to Model Chronic Traumatic Encephalopathy in <em>Drosophila</em> (2017)

Chronic Traumatic Encephalopathy (CTE) is an established neurodegenerative disease that is closely associated with exposure to repetitive mild Traumatic Brain Injury (mTBI). The mechanisms responsible for its complex pathological changes remain largely elusive, despite a recent consensus to define the neuropathological criteria. Here, we describe a novel method to develop a model of CTE in Drosophila melanogaster (Drosophila ) in an attempt to identify the key genes and pathways that lead to the characteristic hyperphosphorylated tau accumulation and neuronal death in the brain. Adjustable-strength impacts to inflict mild closed injury are delivered directly to the fly head, subjecting the head to rapid acceleration and deceleration. Our method eliminates the potential problems inherent with other Drosophila mTBI models (e.g.,animal death might be induced by damage to other parts of the body or to internal organs). The less labor- and cost-intensive animal care, short life span, and extensive genetic tools make the fruit fly ideal to study CTE pathogenesis and make it possible to perform large-scale, genome-wide forward genetic and pharmacological screens. We anticipate that the ongoing characterization of the model will generate important mechanistic insights on disease prevention and therapeutic approaches.
A multi-band multi-beam software-defined passive radar. Part II: Signal processing (2012)

Passive radar has gained considerable popularity in recent times for different types of target detection. This radar uses the so-called “signals of the opportunities” from broadcast, communications or other radar sources that are different in frequency, bandwidth, modulation and spatial location. Instead of following the traditional approach of designing fixed-hardware systems to capture any single opportunistic signal, a better approach is to design a single software defined radar system having the capability to reconfigure itself on-the-fly. This paper presents the software, hardware and signal processing aspects for a software-defined multi-band, multi-beam passive radar. Digital beamforming with switchable antenna arrays is used to form adaptive beams towards targets and transmitters. Multi-band target detection capability is demonstrated through experiments and target tracking results are given at the end. (5 pages)

An Online Social Platform Public Opinion Communication Model Based on BP Neural Network (2023)

With the development of Internet technology, the number of Internet users in China has exceeded 1 billion.Network public opinion has gradually replaced traditional media as an information communication channel.On one hand, the efficient and convenient online platform plays an important role in promoting positive values.But on the other hand, false and even harmful information can also be spread widely through the Internet.Therefore, how to correctly identify the key factors in the communication of public opinion on social platforms and use them to promote or curb them in the process of public opinion communication has become an important issue in the current era of big data.This paper sets the research object as the hot search topic data on the Zhihu platform, and uses the DEA model to initially calculate the relative public opinion transmission efficiency.Then, use the BP neural network and the theory of the strong and weak tie to provide theoretical support for identifying key nodes and key paths of public opinion communication, enhance the work efficiency and effect of the platform supervisors or public opinion operators, and achieve the purpose of promoting positive public opinion communication and curbing negative public opinion communication.

Synthesis of Metal Oxycarbides by Inductively Coupled Radiofrequency Plasma Assisted Magnetron Sputtering Method (2004)

Metal oxycarbide thin films, such as chromium oxycarbide, molybdenum oxycarbide and tungsten oxycarbide films have been synthesized on SUS 304 stainless steel for hard coating at a temperature of 673 K with metal, carbon dioxide and methane by an inductively coupled radiofrequency plasma assisted magnetron sputtering method. The maximum micro-Vickers hardness of the films is more than 20 GPa. X-ray diffraction measurements reveal that the structure of the oxycarbide films is cubic and the lattice constant of them is 0.42-0.43 nm. The films showing a high micro-Vickers hardness are composed of [110] orientated crystallites.
Magnetic and structural properties of CoCrTa films and multilayers with Cr (1990)

We report our studies of epitaxial growth of CoCrTa films on Cr underlayers and the properties of CoCrTa/Cr multilayers. The coercivity, Hc, strongly depends on Ta composition, sputtering conditions, and the thicknesses of the magnetic layer and Cr underlayer. An Hc value of 1300 Oe was obtained for a Ta composition of 2 at. %, a Cr underlayer thickness of 4000 Å, and a magnetic layer thickness of 400 Å. The x-ray data show that the high Hc occurs when crystallites of the Cr underlayer and CoCrTa layer are aligned with the Cr (200) and CoCrTa (110) planes in the film plane. Thus, the c axis of the CoCrTa lies essentially in the plane of the film. When the thickness of the magnetic layer increases above 1000 Å the c axis begins to tip out of the film plane. The basal plane lattice parameter varies roughly linearly with Ta content up to 13 at. %. For the CoCrTa/Cr multilayered films, Hc values up to 1200 Oe were obtained although the c-axis orientation of the magnetic layer becomes somewhat dispersed. Models for the dependence of magnetization reversal on microstructure are discussed.
Mobile image search for tourist information using ACCC algorithm (2010)

Almost all mobile image search applications available in the market only support text queries, which it is sometimes difficult to describe the needs in text and the text input is inconvenient on small devices. This paper proposed a mobile phone image search application that can perform practical image search processing in real-time. The early stage of the project is aimed to develop the application for the tourists who can use it as a guidance tool for travelling in the country. The application can run on hundreds of different mobile phone types and platforms. In older to speed up the visual computation for searching images, the Auto Color Correlogram (ACC) and correlation (ACCC) algorithms based on Correlogram technique were developed. Applying the ACCC algorithm, it reduces the computational complexity of index construction and similarity measurement for images from O(m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> d) to O(md) when compared to previous algorithm, Color correlogram.

Aggregation of Silver Nanoparticle−Dextran Adducts with Concanavalin A and Competitive Complexation with Glucose (2004)

Tiopronin-protected silver nanoparticles (<i>average</i> diameter = 5 nm) were partially displaced by (2-mercapto-propionylamino) acetic acid 2,5-dioxo-pyrrolidin-1-ylesters via ligand exchange, and the succinimide-terminated silver particles were bound to amine-labeled Dextran 3000 (1 amine/per chain) or Dextran 10 000 (2.5 amine/per chain), respectively. The particle-Dextran 10 000 adducts were self-aggregated by interactions of multiple amines on Dextran and multi-functionalized ligands on the particle. The transverse plasmon band was blue shifted while the longitudinal plasmon at 575 nm increased, corresponding to the compact aggregation of particles. The particle-Dextran 3000 adducts, which were not aggregated, were coupled to Concanavalin A (Con A) to facilitate the aggregation of particles. The aggregated particles displayed an absorbance spectral change depending on the mole ratio of Con A/particle-Dextran 3000. The particle-Dextran 3000 adduct was released by a competitive complexation of glucose. This process was monitored by both the change in plasmon absorbance and wavelength, with the glucose concentration. The aggregation and dissociation of Con A/particle-Dextran complexes were also verified by TEM images.
Preparation of Aluminum Oxide Films Under Water Exposure – Preliminary Report on 5052 Series Alloys (2018)

Aluminum fuel cladding will undergo general corrosion with resulting formation of adherent oxide films during in-reactor and post-discharge exposures under various water conditions and temperatures. The presence of oxides with chemically-bound water can pose challenges for extended dry storage due to their potential to decompose and release free water and/or generate gases (e.g., oxygen, hydrogen) due to radiolysis, which may cause corrosion, pressurization, or flammability conditions within the storage container. Therefore, an action plan to identify needed technical and engineering activities and analyses to address the identified knowledge gaps and technical data needs was previously prepared. This report is part of the Task 6 activities of that plan.
An Integer Linear Programming Model for View Selection on Overlapping Camera Clusters (2014)

Multi-View Stereo (MVS) algorithms scale poorly on large image sets, and quickly become unfeasible to run on a single machine with limited memory. Typical solutions to lower the complexity include reducing the redundancy of the image set (view selection), and dividing the image set in groups to be processed independently (view clustering). A novel formulation for view selection is proposed here. We express the problem with an Integer Linear Programming (ILP) model, where cameras are modeled with binary variables, while the linear constraints enforce the completeness of the 3D reconstruction. The solution of the ILP leads to an optimal subset of selected cameras. As a second contribution, we integrate ILP camera selection with a view clustering approach which exploits Leveraged Affinity Propagation (LAP). LAP clustering can efficiently deal with large camera sets. We adapt the original algorithm so that it provides a set of overlapping clusters where the minimum and maximum sizes and the number of overlapping cameras can be specified. Evaluations on four different dataset show our solution provides significant complexity reductions and guarantees near-perfect coverage, making large reconstructions feasible even on a single machine.

Importance of quadrupolar ordering in antiferroelectric liquid crystal devices (2001)

A model of switching in antiferroelectric liquid crystals is presented which predicts both helix unwinding in the pretransitional regime and a field induced transition to the ferroelectric state. When the ratio of the coefficients of the quadrupolar and dipolar ordering terms in the bulk free energy expression exceeds a critical value, the latter transition becomes first order, in agreement with experimental observation. We have determined these coefficients in the commercial mixture CS4001. The ratios of the coefficients imply that all three states (antiferroelectric and two ferroelectric) are stable in the ground state, i.e., antiferroelectric liquid crystals are truly tristable.
Supporting temporal multimedia operations in object-oriented database systems (1994)

Advanced applications in fields like electronic publishing and telecooperation face the problem of handling multimedia information. Conventional database systems do not offer adequate support for storage management as they do not provide for the modeling, indexing, and manipulation of multimedia data. Database management systems need to be extended if they should be able to handle multimedia information like audio and video. In this paper we present an approach of extending the data model of an object-oriented database system by means of schedules which allow for the description of the temporal characteristics of multimedia operations as they occur when modeling time-dependent data like audio and video. First, we present a model of schedules and define the basic concepts and semantics to execute time-dependent operations. Second, we introduce the specification language as an extension to the VODAK Model Language and illustrate the concepts by examples. Finally, we briefly discuss the impact of integrating multimedia data modeling support into a database management system on the system architecture.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Bacterial diarrhea in Laos, a region where cholera was endemic. (1996)

There were cholera outbreaks in Lao PDR since 1993. Two provinces were epidemic areas of cholera in 1993. However the area of cholera occurrence increased to 7 provinces through 1994. Then a bacterial survey had done for the purpose of public health improvement. EPEC was markedly isolated from the hospital in Vientiane. In apparent infection of Salmonella and non-01 Vibrio cholerae with soldiers stationed in the island in Mekong River belong to Vientiane were pointed out. The outbreak of diarrhea in suburban village of Vientiane, the diarrhea was not due to cholera but due to Shigella dysenteriae and Aeromonas sobria. As far as results in the capital city Vientiane and the Vientiane province go, it could say that there was no record and isolation of V. cholerae or non-01 V. cholerae 0139 in this study. On the contrary, Vibrio cholerae 01 serotype Eltor Ogawa was isolated although the community declared the end of the cholera outbreak. This study pointed out the importance of establishing sanitary conditions and health education systems in Lao PDR.
Effects of linear birefringence and polarization-dependent loss of supermirrors in cavity ring-down spectroscopy (2008)

In cavity ring-down spectroscopy (CRDS), residual or stress-induced birefringence (10(-7)-10(-6) rad) of supermirrors will lift the polarization degeneracy of TEM(00) modes and generate two new polarization eigenstates in the cavity with small resonant frequency splitting (approximately 0.1 kHz); the new eigenstates are nearly linearly polarized. When both modes are excited simultaneously, the intracavity polarization state will evolve as the energy decays in the cavity. Without polarization analysis, such mode beating would not be observable. However, real supermirrors have a linear polarization-dependent loss (dichroism) that leads to a change in the loss rate as the polarization state evolves and thus to deviation from the expected single-exponential decay. We develop a model for the evolution of the intracavity polarization state and intensity for a cavity with both birefringence and polarization-dependent loss in the mirrors. We demonstrate, experimentally, that these parameters (both magnitudes and directions) can be extracted from a series of measurements of the cavity decay and depolarization of the transmitted light.

Development of Two Superconducting Energy Gaps in the Aluminum Doped MgB2 (2006)

Point‐contact spectroscopy measurements on the aluminum substituted Mg1−xAlxB2 samples reveal a retention of two superconducting energy gaps in the doping range for x = 0, 0.1 and 0.2. Tc’s of those samples are decreased proportionally to the electron doping from 39 K down to 24 K. The large gap on the σ‐band is decreased proportionally with decreasing Tc. For 10 % Al doped sample MgB2 the small gap is almost unchanged compared to MgB2, but for 20 % Al with Tc = 24 K it is reduced by approximately 15 %. The results are compared with those obtained on carbon doped MgB2. A larger tendency to approach two gaps is found for Al doped MgB2 but the merging of the gaps and the single gap superconductivity is still not realized in the studied doping range.
