Classification of histopathological images using convolutional neural network (2014)

In this work, classification of cellular structures in the high resolutional histopathological images and the discrimination of cellular and non-cellular structures have been investigated. The cell classification is a very exhaustive and time-consuming process for pathologists in medicine. The development of digital imaging in histopathology has enabled the generation of reasonable and effective solutions to this problem. Morever, the classification of digital data provides easier analysis of cell structures in histopathological data. Convolutional neural network (CNN), constituting the main theme of this study, has been proposed with different spatial window sizes in RGB color spaces. Hence, to improve the accuracies of classification results obtained by supervised learning methods, spatial information must also be considered. So, spatial dependencies of cell and non-cell pixels can be evaluated within different pixel neighborhoods in this study. In the experiments, the CNN performs superior than other pixel classification methods including SVM and k-Nearest Neighbour (k-NN). At the end of this paper, several possible directions for future research are also proposed.
An Improved Method for Image Retrieval using Speech Annotation (2003)

In this paper, we present a system for the image indexing and retrieval using speech annotations based on a pre-defined structured syntax. In addition to the introduction of N-best lists for index generation, a query expansion technique is explored to enhance the query terms and to improve retrieval effectiveness. By adding the most probable substitutions for the query terms, more relevant images are distinguished from the data collection. This approach is particularly helpful to deal with those less frequently used words, including out-of-vocabulary (OOV) words, which are very common for names of people and places. Experiments on a collection of 1,200 photos show that the retrieval effectiveness is increased considerably for segment of individual domain on People, Location and Event. With this method, the average value of precision versus recall over a combination of segments has improved significantly, from 50% to 72.4%.

Web-based services for real estate: model and implementation (2004)

E-commerce's impact on real estate is just as significant and multifaceted as in other areas. Its momentum springs from two factors: an increasing population of online customers and increased involvement and investment from the real estate industry. The online real estate business' growing demand for application development has created a new market for application service providers (ASPs) who developed standardized Internet application systems and information services supporting a specific set of business processes. E-commerce success stories have taught companies that every successful e-business must have a feasible business plan that complies with a model. CommRex (Commercial Real Estate Exchange, http://www.commrex.com), a Web-based real estate information system, offers a case study in one such service. CommRex's performance in terms of four characteristics - scalability, portability, operation ability, and availability - is satisfactory, owing to its multiorganization data allocation scheme. During this evolutionary process, the multilevel service model and multiorganization data management structure have been proven an effective choice for such an evolutionary process.
HIGH PERFORMANCE, HIGH-VOLUME FLY ASH CONCRETE FOR SUSTAINABLE DEVELOPMENT (2004)

For a variety of reasons, the concrete construction industry is not sustainable. First, it consumes huge quantities of virgin materials. Second, the principal binder in concrete is portland cement, the production of which is a major contributor to green-house gas emissions that are implicated in global warming and climate change. Third, many concrete structures suffer from lack of durability which has an adverse effect on the resource productivity of the industry. Because the high-volume fly ash concrete system addresses all three sustainability issues, its adoption will enable the concrete construction industry to become more sustainable. In this paper, a brief review is presented of the theory and construction practice with concrete mixtures containing more than 50 % fly ash by mass of the cementitious material. Mechanisms are discussed by which the incorporation of high volume of fly ash in concrete reduces the water demand, improves the workability, minimizes cracking due to thermal and drying shrinkage, and enhances durability to reinforcement corrosion, sulfate attack, and alkali-silica expansion. For countries like China and India, this technology can play an important role in meeting the huge demand for infrastructure in a sustainable manner.
Análisis funcional y optimización de la distribución en planta de una línea de ensamblaje de automóviles (2007)

En la presente Tesis Doctoral se ha analizado una linea de ensamblaje de automoviles y las lineas de premontaje de modulos que la alimentan, como una red de bucles cerrados de maquinas y almacenes intermedios formados por transportadores. Para ello, se han considerado los diferentes parametros que influyen en la transmision de las paradas de cada una de las maquinas al resto del sistema productivo, teniendo en cuenta los regimenes de funcionamiento estacionario y transitorio. A partir de este analisis, ha sido posible determinar las capacidades de los almacenes intermedios que maximizan el tiempo transcurrido entre la parada de cada una de las maquinas y el bloqueo o la falta de alimentacion de la maquina que determina la tasa de produccion del sistema. Este hecho ha permitido la optimizacion de la disponibilidad de la linea de ensamblaje, proponiendose en el presente trabajo la implementacion de un sistema dinamico de almacenes de capacidad variable. El sistema productivo considerado no se puede operar si se dan ciertas proporciones de carrocerias de cuatro puertas entre las estaciones de desensamblaje y ensamblaje de puertas en carroceria. Por este motivo, se han establecido las alternativas que permiten el incremento del rango operacional del sistema, describiendose la implantacion fisica de las mismas. Finalmente, con la ayuda de la tecnica del diseno de experimentos, junto con las tecnicas de regresion lineal multiple, se han obtenido modelos matematicos que permiten analizar y optimizar la produccion del sistema de ensamblaje frente a paradas individualizadas de las maquinas que forman parte del mismo
Size-Exclusion Chromatography with Multi-angle Light Scattering for Elucidating Protein Aggregation Mechanisms (2012)

In this chapter, application of size exclusion chromatography with inline multi-angle light scattering (SEC-MALS) to protein systems is reviewed, in particular for its use in elucidating mechanistic details of net-irreversible aggregation processes. After motivating why SEC-MALS or analogous techniques are natural choices to interrogate such aggregating systems, the individual techniques (SEC and MALS) are reviewed briefly, as needed for the context of the remainder of the chapter. Illustrative examples are provided to highlight when and how SEC-MALS can be applied to test mass-action kinetic models for protein aggregation. Limitations of the technique, as well as recommendations for troubleshooting and potential errors in data interpretation are also provided.
Simple Method for the Covalent Immobilization of Graphene (2009)

We present a simple and efficient method to immobilize graphene on silicon wafers using perfluorophenylazide (PFPA) as the coupling agent. Graphene sheets were covalently attached to PFPA-functionalized wafer surface by a simple heat treatment under ambient conditions. The formation of single and multiple layers of graphene were confirmed by Raman spectroscopy and optical and atomic force microscopy. Evidence of covalent bond formation between graphene and PFPA decorated silicon wafer was given by X-ray photoelectron spectroscopy and sonication treatment.
The serotonin syndrome (1991)

The serotonin syndrome is a toxic condition requiring heightened clinical awareness for prevention, recognition, and prompt treatment. Further work is needed to establish the diagnostic criteria, incidence, and predisposing factors, to identify the role of 5-HT antagonists in treatment, and to differentiate the syndrome from neuroleptic malignant syndrome.
Optimization of Sensor Array Data with Various Pattern Recognition Techniques (2010)

An electronic tongue which composed of selective electrodes is applied to mineral water recognition (optimization of sensor array). The task of the system is to distinguish among five brands of mineral water. For this purpose, various pattern recognition (PARC) procedures are employed: principle components analysis (PCA), independent component analysis, linked-like adaptive genetic algorithm (LAGA), et al. LAGA networks are proved to exhibit the best performance both in array optimization and mineral water recognition. Their further advantages, such as fast training and robustness, make them the suggested pattern classifiers for sensor array data.
Studies on pathogenesis and immunity in tularemia; immune response of the white rat to Bacterium tularense. (1949)

Summary and Conclusions 1.The agglutinin response in rats vaccinated against Bact. tularense is very rapid and the initial rise parallels roughly the time at which immunity to infection develops. 2.The agglutinin titer in vaccinated, recovered and normal rats after infection, rises rapidly and continues at a high level for a longer period than after vaccination. 3.A high degree of active immunity after vaccination of the rat was found to persist for as long as 99 days whereas a high titer of agglutinins persisted for only 11 to 17 days. 4.Rats are more solidly immune after recovery from infection than after vaccination with killed cultures. This immunity also persists at a high level for at least 114 days. 5.Normal, vaccinated and recovered rats were shown to harbor living organisms in the spleen for 31 to 46 days after infection.
Grammont's reverse shoulder prosthesis for rotator cuff arthropathy. A retrospective study of 32 cases. (2004)

The authors have retrospectively studied a series of 32 reverse shoulder prostheses implanted in 30 patients by the same surgeon between 1992 and 2000. The mean age was 71 years; 26 patients were female, 4 were male. Thirteen patients (14 prostheses) were clinically and radiologically examined at follow-up; 9 patients (10 prostheses) were questioned by telephone and their radiological records were studied. With a mean follow-up of 31 months, 92 % (22/24) were entirely satisfied with the operation. The mean Constant score for the 14 shoulders which were clinically evaluated at follow-up was 60/100. There was one failure, related with glenoid loosening. These findings are in line with the good short-term results previously reported with this prosthesis. Glenoid notching is a well-known problem with the reversed prosthesis; it may lead to implant failure. We noted such an image in 50 % of our patients. In several cases however, the radiological finding was more suggestive of osteophytic formation than of real bony erosion, an observation that has not been reported before. The image remained stable over time and did not lead to glenoid loosening within the time limits of the study. Nevertheless, notching remains a concern with respect to the long-term survival of these implants which should therefore, in our opinion, be used only in elderly patients. Whether improved technique or design modification can address this issue still has to be established.
Automotive electronics: Drivers get more options in 1983: Car makers embrace electronics in an all-out drive to improve performance, handling, fuel economy, riding quality, driver aids, and entertainment (1982)

Discusses the use of electronics by some car makers to improve performance, handling, fuel economy, driver aids and entertainment. The Ford Motor Co., for example, is introducing its fourth-generation control system, the EEC-IV, which handles nearly 1 million commands per second with its two Intel microcircuits, an 8061 microprocessor and an 8361 ROM. Microprocessors are also controlling car suspension systems to maintain riding quality and vehicle attitude throughout a range of loading conditions. A sample of available electronic displays include travel computers, warning systems, on-board diagnostics, digital readouts, electronic bar graphs and navigation aids.
FIELD CHAMBER MEASUREMENTS OF CO2 FLUX FROM SOIL SURFACE (1974)

Rates of carbon dioxide exchange were determined using an infrared gas analyzer in an open chamber system in a field. During 1971 a fan was used to draw air through the chamber; the measured CO2 flux was approximately 40 percent greater than the highest rate reported in the literature. In 1972 two chambers were used: one under slight suction and the other under a slight pressure (compared with atmospheric pressure). The CO2 flux from the soil surface inside the “pressure” chamber was nearly an order of magnitude lower than inside the “suction” chamber. Dispersion equations were used to separate mass flow and diffusion components of the total flux. Simplified analysis showed that mass flow could account for the large CO2 flux with slight negative pressures inside the chamber.
A Comparison of SIFT and SURF (2013)

Accurate, robust and automatic image registration is critical task in many applications. To perform image registration/alignment, required steps are: Feature detection, Feature matching, derivation of transformation function based on corresponding features in images and reconstruction of images based on derived transformation function. Accuracy of registered image depends on accurate feature detection and matching. So these two intermediate steps are very important in many image applications: image registration, computer vision, image mosaic etc. This paper presents two different methods for scale and rotation invariant interest point/feature detector and descriptor: Scale Invariant Feature Transform (SIFT) and Speed Up Robust Features (SURF). It also presents a way to extract distinctive invariant features from images that can be used to perform reliable matching between different views of an object/scene.

A study of network optimization model and algorithm for carrying capacity of station throat (2002)

With the railway transportation opening for the market, the travelling speed of large number of trains becoming faster, and the kinds of trains, operation styles and time arrangement being more variable, the dynamic complexity of the operation capacity of railway station throat pops out than ever before. Thus, in order to meet the requirements of railway upgrading and evaluation, the advanced and accurate methods and tools are needed. This paper models the layout and configuration of the station throat and operation processes. The network optimization model of throat operation arrangement and the compound staged decision model of throat opration capacity are presented. Furthermore the computer based algorithms for the models are given out. At last, the models and algorithms are justified with the calculation results of simulation for the practical operations.
Measurements of absolute photoionisation cross sections of Ga<sup>+</sup>and Zn<sup>+</sup>ions (1987)

Measurements are reported of absolute photoionisation cross sections of Zn+ and Ga+ ions by VUV radiation. Both cross sections were dominated by autoionisation resonances. For Ga+ the largest resonances had cross sections of 3*10-16 cm2 and were centred about 21.88 eV. This is similar to the energy of 21.9 eV calculated by Pindzola et al (1982) for 3d104s2 to 3d94s24p 3P1. Comparisons were also made with the spectrum of atomic zinc measured by Marr and Austin (1969). For Zn+ some photoionisation resonances could be related to autoionising transitions in the electron impact ionisation cross sections reported by Rogers et al (1982) but the strongest electron-impact-induced transition does not appear in the photoionisation spectrum.
An Active Acoustic Metamaterial With Tunable Effective Density (2010)

Extensive efforts are being exerted to develop various types of acoustic metamaterials to effectively control the flow of acoustical energy through these materials. However, all these efforts are focused on passive metamaterials with fixed material properties. In this paper, the emphasis is placed on the development of a class of one-dimensional acoustic metamaterials with tunable effective densities in an attempt to enable the adaptation to varying external environment. More importantly, the active metamaterials can be tailored to have increasing or decreasing variation of the material properties along and across the material volume. With such unique capabilities, physically realizable acoustic cloaks can be achieved and objects treated with these active metamaterials can become acoustically invisible. The theoretical analysis of this class of active acoustic metamaterials is presented and the theoretical predictions are determined for an array of fluid cavities separated by piezoelectric boundaries. These boundaries control the stiffness of the individual cavity and in turn its dynamical density. Various control strategies are considered to achieve different spectral and spatial control of the density of this class of acoustic metamaterials. A natural extension of this work is to include active control capabilities to tailor the bulk modulus distribution of the metamaterial in order to build practical configurations of acoustic cloaks.
Intelligent Method for Identifying Driving Risk Based on V2V Multisource Big Data (2018)

Risky driving behavior is a major cause of traffic conflicts, which can develop into road traffic accidents, making the timely and accurate identification of such behavior essential to road safety. A platform was therefore established for analyzing the driving behavior of 20 professional drivers in field tests, in which overclose car following and lane departure were used as typical risky driving behaviors. Characterization parameters for identification were screened and used to determine threshold values and an appropriate time window for identification. A neural network‐Bayesian filter identification model was established and data samples were selected to identify risky driving behavior and evaluate the identification efficiency of the model. The results obtained indicated a successful identification rate of 83.6% when the neural network model was solely used to identify risky driving behavior, but this could be increased to 92.46% once corrected by the Bayesian filter. This has important theoretical and practical significance in relation to evaluating the efficiency of existing driver assist systems, as well as the development of future intelligent driving systems.
Comparison of a sidestream and mainstream capnometer in infants (1989)

This study was designed to compare capnograms obtained from a sidestream and mainstream capnometer during rapid mechanical ventilation in infants. Ten infants were studied during elective anesthesia and surgery. Simultaneous recordings of exhaled CO2 were made with a sidestream and a mainstream machine; arterial blood gases were measured for comparison. The mean arterial to end-tidal CO2 difference (PaCO2-PetCO2) was approximately 5 torr with either technique; the correlation of PetCO2 with PaCO2 was slightly better with the mainstream analyzer (r2 = .895 vs. .654). The recordings obtained with the sidestream machine were grossly distorted, with flattening of the ascending limb (slope 37.3 vs. 153.3 torr/sec, sidestream vs. mainstream, p less than .001) and absence of the alveolar plateau. The mainstream analyzer gives a more accurate representation of the expired CO2 waveform in small children at rapid respiratory rates.
Dynamic size and speed cursor for large, high-resolution displays (2006)

As larger displays become more available their lack of adequate input techniques becomes apparent. In this paper we show the scalability of the dynamic size and speed cursor for large, high-resolution displays. We introduce the idea of a dynamic paradigm for input devices, explain three implementations of the dynamic size and speed (DSS) cursor and explain results of an experiment. In our experiment we compared the three different implementations of the dynamic size and speed cursor to cursor warping and standard cursor settings. In the experiment we found gender bias for two different tasks (clicking and simple drag and drop), found that one of the dynamic size and speed cursor implementations generally outperformed cursor warping and the standard cursor setting, and explain how distance to and size of targets effected results. We conclude by suggesting the use of a dynamic size and speed cursor with large, high-resolution displays.
Controlled chemical synthesis of CaO<sub>2</sub> particles coated with polyethylene glycol: characterization of crystallite size and oxygen release kinetics (2017)

The oxygen release pattern of CaO<sub>2</sub> nanoparticles was biphasic: an initial burst phase for the first 24 hours followed by a descending release rate for three days. The oxygen release rate in the second phase mainly depended on the shrinking-core model for CaO<sub>2</sub> hydrolysis.
Trefoil peptides: a newly recognized family of epithelial mucin-associated molecules (1993)

Members of the trefoil family of peptides are generally small stable secreted molecules, structurally related by the presence of one, or up to six, compact 6-cysteine motifs. Several trefoil peptides are expressed in mammalian gut and Xenopus gut and skin, often in association with mucins. Chronic ulcerative conditions of the gut, such as Crohn's disease, result in the growth of glandular structures of the ulcer-associated cell lineage (UACL) that secrete epidermal growth factor/urogastrone, transforming growth factor-alpha, and at least three trefoil peptides [pS2, human spasmolytic polypeptide (hSP), and intestinal trefoil factor (hITF/hP1.B)]. Neuroendocrine and goblet cells near the UACL are "recruited" into expressing pS2 and hSP, but the purpose of this concerted expression is unclear. A role in mucosal healing has been proposed. Biological functions of trefoil peptides have been difficult to establish. Pancreatic spasmolytic polypeptide of porcine origin inhibits gastric acid secretion and smooth muscle contraction and is a growth factor for some cultured cells, but pS2, once thought to be breast cancer specific, is not a mitogen. Recombinant trefoil peptides have allowed localization of binding sites and will allow structure-activity relationships to be studied, once the functions are clear.
