Windowed Fourier transform method for demodulation of carrier fringes (2004)

The Fourier transform method for demodulation of carrier fringes has been extensively developed and widely used in optical metrology. However, the Fourier transform being a global operation, it has poor ability to localize the signal properties and hence the result of FTM is not ideal. A windowed Fourier transform method is thus proposed, with advantages of signal localization and noise filtering. An example demonstrates the improved result compared to the traditional Fourier transform.
Study on the Application of Lean Construction Supply Chain Management in EPC Project (2012)

Although EPC mode has been applied increasingly in the past decade in China, the outcome of its implementation has been proved to be unsatisfactory. Actually, in most of our EPC projects, their supply chains are filled with various kinds of waste and luxurious coordination cost mainly due to uncooperative behavior and adversarial relationship among construction supply chain (CSC) parties/actors. These problems have greatly affected the effectiveness of our EPC project management as well as the comprehensive performance of our CSC. The reason can be largely attributed to the lack of advanced project management thinking and appropriate EPC project management model. This essay is to introduce lean construction supply chain management model to EPC project, aiming at applying lean thinking as well as relevant lean technologies to solve the major problems of our EPC project management and improve the overall competence of our CSC. It also fully discusses some key issues closely relevant to the implementation of LCSCM in EPC project.
Kinetics of plasma Epstein-Barr virus DNA during radiation therapy for nasopharyngeal carcinoma. (2000)

We studied the kinetics of circulating EBV DNA in the plasma of nasopharyngeal carcinoma (NPC) patients. Serial weekly sampling of 10 NPC patients revealed a rapid decline in plasma EBV DNA concentration after treatment. In two subjects, an initial rise in the circulating EBV DNA level was observed immediately after treatment initiation. Plasma EBV DNA levels were monitored daily during the first treatment week in a second cohort of five patients, and the results indicated that an initial rise in plasma EBV DNA concentration could be observed in all subjects during the first treatment week. This observation is consistent with the liberation of EBV DNA after therapy-induced cancer cell death. After this initial rise, plasma EBV DNA concentration was found to decay with a median half-life of 3.8 days (interquartile range, 2.4-4.4 days). Kinetic analysis of circulating tumor-derived DNA during treatment may be a powerful tool for evaluating the in vivo response of NPC and other tumors to antineoplastic treatment and may improve our understanding of the biology of plasma nucleic acids.
Serpentine Coil Topology for BNL Direct Wind Superconducting Magnets (2006)

Serpentine winding, a recent innovation developed at BNL for direct winding superconducting magnets, allows winding a coil layer of arbitrary multipolarity in one continuous winding process and greatly simplifies magnet design and production compared to the planar patterns used before. Serpentine windings were used for the BEPC-II Upgrade and JPARC magnets and are proposed to make compact final focus magnets for the ILC. Serpentine patterns exhibit a direct connection between 2D body harmonics and harmonics derived from the integral fields. Straightforward 2D optimization yields good integral field quality with uniformly spaced (natural) coil ends. This and other surprising features of Serpentine windings are addressed in this paper.
Robust Local Outlier Detection (2015)

With the rapid expansion of data scale, big data mining and analysis has attracted increasing attention. Outlier detection as an important task of data mining is widely used in many applications. However, conventional outlier detection methods have difficulty handling large-scale datasets. In addition, most of them typically can only identify global outliers and are over sensitive to parameters variation. In this paper, we propose a robust method for robust local outlier detection with statistical parameters, which incorporates the clustering based ideas in dealing with big data. Firstly, This method find some density peaks of dataset by 3s standard. Secondly each remaining data object in the dataset is assigned to the same cluster as its nearest neighbor of higher density. Finally, we use Chebyshevs inequality and density peak reachability to identify local outliers of each group. The experimental results demonstrate the efficiency and accuracy of the proposed method in identifying both global and local outliers, Moreover, the method also proved more robust analysis than typical outlier detection methods, such as LOF and DBSCAN.

Improving the Breadth of the Host’s Immune Response to Lassa Virus (2018)

In 2017, the global Coalition for Epidemic Preparedness (CEPI) declared Lassa virus disease to be one of the world’s foremost biothreats. In January 2018, World Health Organization experts met to address the Lassa biothreat. It was commonly recognized that the diversity of Lassa virus (LASV) isolated from West African patient samples was far greater than that of the Ebola isolates from the West African epidemic of 2013–2016. Thus, vaccines produced against Lassa virus disease face the added challenge that they must be broadly-protective against a wide variety of LASV. In this review, we discuss what is known about the immune response to Lassa infection. We also discuss the approaches used to make broadly-protective influenza vaccines and how they could be applied to developing broad vaccine coverage against LASV disease. Recent advances in AIDS research are also potentially applicable to the design of broadly-protective medical countermeasures against LASV disease.
An Integrated Study of Reservoir Compartmentalization at Ewing Bank 873, Offshore Gulf of Mexico (1998)

Abstract Ewing Bank 873 is an offshore Gulf of Mexico field discovered in 1991 in 775 ft of water. The discovery well was drilled on a seismic amplitude anomaly on the flank of a salt withdrawal mini-basin. Field development began in 1994, and in mid 1998 daily production from the Bulminella 1 reservoir averaged 40,000 BOPD and 32 × 106 ft3/D of gas. The Bul 1 reservoir in this combination structural-stratigraphic trap consists of six stacked and overlapping Pliocene turbidite sand lobes. In turn, integration of seismic, well log, geochemical and pressure data indicates these six turbidite lobes comprise three compartments. All of the various data types give constraints on different aspects of compartmentalization, but at the stratigraphically complex Ewing Bank 873 field, geochemical analyses provided key information unavailable through any other means. These geochemical analyses were performed as individual wells in the field went on production and immediately provided information regarding fluid communication and reservoir connectivity that was missing from earlier interpretations based solely on seismic and log data. Early recognition of three reservoir compartments using geochemical data also helped constrain preliminary stratigraphic interpretations and provided initial input for flow units and reservoir simulation models. The geochemical information further provided advance notice of economically significant oil quality variations in the three compartments. These fluid variabilities were later substantiated by PVT analyses and include notable differences in oil gravity, weight percent sulfur, viscosity and solution gas. Integrating all available data shows there are three compartments at EW 873 and each compartment comprises different turbidite sand lobes and exhibits its own characteristic pressure regime and fluid properties. The early indications of both compartmentalization and variation in fluid properties by the geochemical analyses contributed significantly to improved field recovery and economics by allowing fewer and better placed wells to be drilled.

The Myth of the Genetically Sick African (2022)

Western medicine has an unfortunate history where it has been applied to address the health of African Americans. At its origins, it was aligned with the objectives of colonialism and chattel slavery. The degree to which medical “science” concerned itself with persons of African descent was to keep them alive for sale on the auction block, or to keep them healthy as they toiled to generate wealth for their European owners. Medicine in early America relied upon both dead and live African bodies to test its ideas to benefit Europeans. As medicine moved from quackery to a discipline based in science, its understanding of human biological variation was flawed. This was not a problem confined to medicine alone, but to the biological sciences in general. Biology had no solid theoretical basis until after 1859. As medicine further developed in the 20th century, it never doubted the difference between Europeans and Africans, and also asserted the innate inferiority of the latter. The genomic revolution in the latter 20th century produced tools that were deployed in a biomedical culture still mired in “racial” medicine. This lack of theoretical perspective still misdirects research associated with health disparity. In contrast to this is evolutionary medicine, which relies on a sound unification of evolutionary (ultimate) and physiological, cellular, and molecular (proximate) mechanisms. Utilizing the perspectives of evolutionary medicine is a prerequisite for an effective intervention in health disparity and finally dispelling the myth of the genetically sick African.

Performance of four slide agglutination methods for identification of Staphylococcus aureus when testing methicillin-resistant staphylococci (1987)

Four commercially available slide agglutination systems for identifying Staphylococcus aureus were compared with the conventional slide (clumping factor) and tube coagulase tests. The systems evaluated included Bacto Staph Latex (Difco Laboratories, Detroit, Mich.), Staphyloslide (BBL Microbiology Systems, Cockeysville, Md.), Mini ID Accu-Staph (Carr-Scarborough Microbiologicals, Inc., Decatur, Ga.), and Staphaurex (Wellcome Diagnostics, Research Triangle Park, N.C.). A total of 338 clinical isolates, including methicillin-resistant S. aureus (n = 149), methicillin-susceptible S. aureus (n = 78), methicillin-resistant, coagulase-negative staphylococci (n = 45), and methicillin-susceptible, coagulase-negative staphylococci (n = 66), were tested by each method. The slide test for clumping factor, the 4-h tube coagulase test, Bacto Staph Latex, Staphyloslide, Mini ID Accu-Staph, and Staphaurex detected 212 (93.4%), 218 (96%), 223 (98.2%), 223 (98.2%), 221 (97.4%), and 224 (98.7%) of the S. aureus (44% methicillin-resistant) isolates, respectively. There were no false-positive results with any of the methods when the 111 strains of coagulase-negative staphylococci were tested. The results of this evaluation suggest that the four slide identification methods tested can provide rapid and accurate identification of methicillin-resistant S. aureus strains.

Remote Tele-assistance System for Maintenance Operators in Mines (2011)

ABSTRACT: Complex technologies such as fully automated and semi-automated equipment and teleoperated machines are being introduced to improve productivity in mines. Consequently, the maintenance and operation of these complex machines is becoming an issue. There is a growing interest in industry in the use and development of technologies to support the collaboration between a local worker and a remote helper to deliver expertise to guide the local worker in undertaking maintenance and other activities. The productivity of the future mine relies on the effective delivery, of remote guidance. ReMoTe (Remote Mobile Tele-assistance), a mobile augmented reality system for remote guiding, has been developed at CSIRO as part of the work in the Transforming the Future Mine Theme.

A condition-based failure-prediction and processing-scheme for preventive maintenance (2003)

Preventive maintenance (PM) is an effective approach for reliability enhancement. Time-based and condition-based maintenance are two major approaches for PM. In contrast, condition-based maintenance can be a better and more cost-effective type of maintenance than time-based maintenance. However, irrespective of the approach adopted for PM, whether a failure can be detected early or even predicted is the key point. This paper presents a failure prediction method for PM by state estimation using the Kalman filter. To improve preventive maintenance, this study uses a hybrid Petri-net modeling method coupled with fault-tree analysis and Kalman filtering to perform failure prediction and processing. A Petri net arrangement, viz, early failure detection and isolation arrangement (EFDIA), is used; it facilitates alarm, early failure detection, fault isolation, event count, system-state description, and automatic shutdown or regulation. These functions are very useful for health-monitoring and preventive-maintenance of a system. This study implements EFDIA to an application-specific integrated circuit on a Xilinx Demonstration Board. A condition-monitoring system of a thermal power plant is used as an example to demonstrate the proposed scheme. Linking the Kalman filter to the EFDIA Petri net, a condition-based failure prediction and processing scheme has been completed for preventive maintenance. This paper presents a failure prediction and processing scheme for PM via the thermal power-plant example, by using a hybrid Petri net modeling method endowed with fault-tree analysis and Kalman filtering. The FPN (Petri net dealing with system failure) has to be constructed beforehand. The next step is to obtain control charts for all fault places in the FPN in order to prescribe thresholds and increment times for every step in Kalman prediction. Afterwards, the system model of each place in the FPN must be derived to perform Kalman filtering. With these prerequisites, this method can be applied to any system. The proposed Petri net approach not only can achieve early failure detection and isolation for fault diagnosis but also facilitates event count, system state description, and automatic shutdown or regulation. These capabilities are very useful for health monitoring and PM of a system. Since the triggering signal of S/sub i/ place of the EFDIA in Section IV (S/sub i/ is a place for the Kalman-predicted indicator value of the sensing signal for the Petri net dealing with system failure) indicates that subsystem #i performance is going to reach the prescribed failure threshold, the signal can be provided via the Kalman filtering method in Section III. Linking the Kalman filter to the EFDIA Petri net, a condition-based failure prediction and processing scheme has been completed for preventive maintenance.

TEAM: Trust-Extended Authentication Mechanism for Vehicular Ad Hoc Networks (2013)

The security of vehicular ad hoc networks (VANETs) has been receiving a significant amount of attention in the field of wireless mobile networking because VANETs are vulnerable to malicious attacks. A number of secure authentication schemes based on asymmetric cryptography have been proposed to prevent such attacks. However, these schemes are not suitable for highly dynamic environments such as VANETs, because they cannot efficiently cope with the authentication procedure. Hence, this still calls for an efficient authentication scheme for VANETs. In this paper, we propose a decentralized lightweight authentication scheme called trust-extended authentication mechanism (TEAM) for vehicle-to-vehicle communication networks. TEAM adopts the concept of transitive trust relationships to improve the performance of the authentication procedure and only needs a few storage spaces. Moreover, TEAM satisfies the following security requirements: anonymity, location privacy, mutual authentication, forgery attack resistance, modification attack resistance, replay attack resistance, no clock synchronization problem, no verification table, fast error detection, perfect forward secrecy, man-in-the-middle attack resistance, and session key agreement.
Performance of Combined Amplitude and Phase-Modulated Communication Systems (1960)

The performance of two types of digital phase-and amplitude-modulated systems is investigated for the high signal-to-noise ratio region. Approximate expressions for the probability of error and channel capacity of the more optimum of these two systems are compared with corresponding expressions for probability of error and channel capacity for a digital phase-modulated system. It is shown that the phase- and amplitude-modulated systems show a definite power advantage over the phase-only system when the information content per transmitted symbol must be greater than 3 bits. From a channel capacity standpoint, the phase- and amplitude-modulated systems make more efficient use of the channel for signal-to-noise ratios greater than 11 db. The more optimum of the two phase and amplitude systems has only a 3-db advantage over the less optimum and is considerably more difficult to instrument.
E.P.U. problems (2014)

In the present article Dr. Guido Carli, chairman of the European Payments Union Managing Board, summarises the core of his observations on the union’s problems in the following conclusions: (a) within the present E.P.U. Agreement, a combination of credit and debit positions may arise which would exhaust the dollar assets and therefore terminate the working of the institution; (b) the situation could be redressed by decreasing quotas, by altering the dollar-credit ratio within the quotas, by contributing an additional supply of dollars. This fresh contribution is liable to come either from participating countries or from U.S.A.; but as all participating countries are running a dollar deficit a contribution of theirs would increase this deficit; (c) whatever device under (b) be accepted, it would be insufficient to restore normal working conditions in E.P.U. if participating countries did not pursue economic and monetary policies calculated to bring about equilibrium of their balances of payments.
