Circuit for simultaneous measurements of particle sizing interferometer signal characteristics (1987)

Particle sizing interferometer (PSI) signal characteristics, including visibility, peak intensity, number of Doppler signal cycles, and pedestal intensity, are examined for simultaneous use in particle sizing. Requirements are defined for circuitry which can simultaneously measure these characteristics and can be implemented in an existing PSI signal processor. The circuitry was implemented and tested using a rotating wheel and latex spheres. The experimental results confirm circuit reliability.
Visual Detection of <i>Mycobacterium t</i><i>uberculosis</i> Complex with Loop-Mediated Isothermal Amplification and Eriochrome Black T (2014)

The present study was aimed to improve the method for detecting Mycobacterium tuberculosis complex recently reported on Letters in Applied Microbiology. Eriochrome black T (EBT) was added to the reaction system of LAMP, due to complexation of EBT with magnesium ions, the color of reaction solution was red at beginning, when the reaction was in process, the precipitate of magnesium ions and pyrophosphate ions formed, EBT lost magnesium ions, the color of reaction solution became sky blue from red gradually, and the method exhibits a high sensitivity of 8 fg/μL. The improved LAMP assay can detect Mycobacterium tuberculosis complex rapidly, sensitively and visually, the method developed in this study had solved the “bottleneck” in popularization and application of LAMP technology, which had not only avoided aerosol pollution but also solved the false positive problem caused by primer dimers.
Clinical experience with intravenous metoprolol in supraventricular tachyarrhythmias. A multicentre study. (1981)

The efficacy of metoprolol, 5-15 mg i.v., in the treatment of supraventricular tachyarrhythmias was evaluated in a multi-centre study involving 142 patients, 28 of whom had paroxysmal atrial tachycardia, 35 atrial flutter and 79 atrial fibrillation. A good control of heart rate (reduction of greater than or equal to 25% or to less than 100 beats/min) was obtained in 68% of the patients and a further 18% showed a reduction in heart rate of at least 10% or to less than or equal to 150 beats/min. Conversion to sinus rhythm occurred in 57% of the patients with paroxysmal atrial tachycardia. As would be expected, the conversion rate was lower in patients with atrial flutter or fibrillation (23% and 13%, respectively). The drug was well tolerated, and marked hypotension or hypotensive symptoms occurred mainly in patients with initial hypotension or congestive heart failure. The effects observed in this study are in agreement with previous reports for other beta-blocking agents.
Effect of doxazosin on blood pressure and renal haemodynamics of hypertensive patients with renal failure. (1986)

Doxazosin, a quinazoline derivative, has alpha 1- adrenoreceptor antagonist properties similar to those of prazosin. This antihypertensive agent has a longer elimination half-life than prazosin. The pharmacokinetic properties of doxazosin are not significantly different in patients with renal insufficiency compared with healthy controls. In this study eight hypertensive patients with renal insufficiency were studied during a two week washout period, followed by a two week single blind placebo phase and an eight week open doxazosin treatment period. Doxazosin was commenced in a dose of 1 mg daily and titrated if necessary, with the dose being doubled every two weeks. In all but one patient doxazosin was successful in controlling the blood pressure. Treatment with doxazosin for eight weeks had no adverse effects on the effective renal plasma flow or glomerular filtration rate of these patients. Six of the eight patients suffered side effects attributable to doxazosin.
Latest Developments in Acoustic Subsea Control and Monitoring for the Drilling Industry (2011)

Abstract This presentation will review the case for secure, high reliability acoustic signalling through water, with applicability to communication, monitoring and control requirements. Illustrations will be drawn from NASBOP to provide an example of critical data being transmitted and received acoustically in the deepwater Oil and Gas arena today. Advances in Digital Acoustic Technology and the specific inception of spread spectrum communication technology have resulted in high integrity, high reliability transmission and reception of critical command and control data from Subsea BOP to surface vessels. These systems have unique ability to operate reliably in deep water, high multipath environments with greater than 99% reliability. The foundation of Nautronix signalling is ADS2 (Acoustic Digital Spread Spectrum) technology. Proven ADS2 technology allows high integrity data transmission and excellent immunity to interference. Its long range capability (in excess of 5km dependent on environmental conditions) as well as reduced battery consumption, makes this technology the ideal solution as primary or secondary data management and communication. Ultimately, this technology will provide options for a wide range of life of field applications in the future. NASeBOP, using ADS2 technology, provides the solution from a subsea control perspective without the traditional umbilical to remotely monitor other subsea equipment and retrieve data such as pressure/temperature wirelessly. NASeBOP provides 16 critical functions with feedback for the Subsea Isolation Device and allows for read-back of 8 analogue sensors to monitor critical subsea pressure and temperature readings. The system also allows the ability to activate an Emergency Disconnect Sequence (EDS) and to monitor the BOP status after disconnect. The next evolution of BOP control is NASMUX; using 128 channels to fully control and monitor the BOP with acoustics. This technology will revolutionise BOP operations by addressing many of the current issues by providing a reduction of umbilical's and reels, elimination of downtime caused by umbilical damage and increased safety by reduction of moon-pool activity in handling of umbilical's. The system would provide full BOP functionality in the event of umbilical failure, in order to allow the operator to safely shut in a well before recovery for umbilical repair.
Fuzzy based hybrid approach for user request prediction using Markov model (2015)

Web Usage Mining (WUM) is an important type of Web mining, which deals with extraction of interesting knowledge from the web log files. Web prediction is a classification problem in which we attempt to predict the next set of Web pages that a user may visit based on the knowledge of the previously visited pages or browsing history. It is very beneficial to predict user's behavior while he/she is serving the internet for many reasons like increasing browsing speed or minimization of server load etc. In this paper we have proposed fuzzy based hidden Markov model for predicting user's next process. Our proposal is modified version of all-Kth Markov model. This paper also reports the comparisons of various methods for future request prediction with their appropriate application. This complete work provide us the overview of user request prediction and also provide its possible solutions which will help in further research for new development in this area.
Face Recognition Based on Local Binary Patterns with Threshold (2010)

This paper presents a novel and efficient face recognition technique based on Local Binary Pattern (LBP) with threshold for resolving traditional LBP's weakness of extracting global features. By setting a threshold to enhance the robustness to noise such as light and extract the global features of face preferably. Combining the local features by LBP with global features as the total features of the image is more power discriminating. Principal Component Analysis (PCA) and linear discriminate analysis (LDA) are used to reduce the dimensionality and optimize discriminative recognition respectively. The proposed method is tested and evaluated not only on ORL datasets but also on YALE datasets and yields a recognition rate of 98%, the experimental results show that the method is valid and feasible.
Efficient and durable AR coatings for Ge in the 8–115-μm band using synthesized refractive indices by evaporation of homogeneous mixtures (1983)

The development of an efficient and durable medium band antireflective coating on germanium for the 8–11.5-μm wavelength region is described. The minimal average reflectance of a double-layer stack is calculated as a function of a varying index of one of the layers, while the second chosen index is kept constant. In this way a comprehensive display of the outcome of various material combinations can be obtained. A homogeneous CdTe/CeF3 double layer is compared to improved coatings, in which the outer layer's index is synthesized by single-source evaporation of mixtures of CeF3 + SrF2 and CeF3 + SrF2 + CaF2. The addition of a Y2O3 binding layer and the inhomogeneous mixing of the two layer materials at the phase interface by coevaporation significantly improved the durability of the coating.
High-performance and power-efficient CMOS comparators (2003)

Several design techniques for high-performance and power-efficient CMOS comparators are proposed. First, the comparator is based on the priority-encoding (PE) algorithm, and the dynamic circuit technique developed specifically for the priority encoder can be applied. Second, the PE function and the subsequent logic functions are merged and efficiently realized in the multiple output domino logic (MODL) to result in a shortened logic depth. The circuit in MODL CMOS is also compact and power efficient because few transistors are needed. Third, the multilevel look-ahead technique is used to shorten the path of priority-token propagation. Finally, the circuit is realized with a latch-based two-stage pipelined structure, and the comparison function is partitioned into two parts, with each part executed in each half of the clock cycle in a delay-balanced manner. Post-layout simulation results show that a 64-b comparator designed with the proposed techniques in a 3-V 0.6-μm CMOS technology is 16% faster, 50% smaller, and 79% more power efficient as compared with the all-n-transistor comparator, which is the fastest among the conventional comparators. Measurement results of the test chip conform with simulation results and prove the feasibility of the proposed techniques.

Evaluation of the Instrumented Ball Impact Procedure to Assess Head Impact Protection in Airplanes (1995)

<div class="htmlview paragraph">The instrumented ball impact test procedure, defined in Federal Aviation Administration (FAA) Advisory Circular (AC) 25-17, is one of the means of compliance with requirements for head impact protection for structures in aircraft interiors. A series of tests was performed based on this procedure, using a 13 lb. and a 16 lb. bowling ball instrumented to measure impact accelerations. Drop tests with the ball were conducted on various materials, including Ensolite and rigid foam pads. The results of the instrumented ball tests were compared with head impact results on the same pad materials in sled tests using an anthropomorphic test dummy (ATD). A comparison of the instrumented ball pass/fail criteria of AC 25-17 and the contemporary Head Injury Criteria (HIC) from ATD head impacts is presented.</div>

Improved SLM for PAPR Reduction in OFDM System (2007)

Selected mapping (SLM) is a promising peak-to-average power ratio (PAPR) reduction technique for orthogonal frequency division multiplexing (OFDM) system. In SLM, phase sequences are combined with the data for generating alternative signals, so as to reduce the PAPR. In this paper, a new criterion is developed to examine the effects of different phase sequence sets in SLM-OFDM based on the mathematical correlation analysis among the alternative signals. Furthermore, according to the proposed criteria, the chaotic phase sequence set is introduced for improving the PAPR reduction performance in SLM. Simulation results show that the improved SLM outperforms conventional methods such as proposed in [6].
65 PRODUCTION OF PORCINE NUCLEAR TRANSFER EMBRYOS USING FETAL FIBROBLAST CELLS ANALYZED ON APOPTOSIS (2004)

One of the most important factors that determine the developmental potential of mammalian cloned embryos is the structuro-functional quality of nuclear donor cells. Biochemical changes that are some of the earliest symptoms of apoptosis signal transduction are not reflected in the morphological features of somatic cells. Therefore, an appropriate system of cell selection would enable the sorting of donor nuclei with high morphological and biochemical susceptibility to somatic cloning. The aim of our study was to examine the in vitro developmental competencies of porcine nuclear transfer (NT) embryos reconstructed with fetal fibroblast cells that had been analyzed for apoptosis by live-fluorescent labelling. Frozen/thawed fetal fibroblast cells, which had been in vitro-cultured to a confluent state, were used for analysis. To detect the early apoptotic changes in the fibroblast cells, a single cell suspension of nuclear donor cells was subjected to dyeing with live-DNA green fluorochrome YO-PRO-1. The recipient cells were in vitro-matured oocytes. Maternal chromosomes were removed by a chemically assisted microsurgical technique. Then, single nuclear donor cells were inserted into the perivitelline space of enucleated oocytes. Fibroblast cell-ooplast couplets were simultaneously fused and activated with two consecutive DC pulses of 1.2 kV/cm for 60 µs. Reconstructed embryos were in vitro cultured in 50-µL drops of NCSU-23 medium supplemented with 0.4% BSA-V for 6 to 7 days at 38.5°C in a humidified atmosphere of 5% CO2 and 95% air. The rates of cleavage and development to morula/blastocyst stages were examined on Days 2 and 6/7, respectively. After fluorescent analysis of approximately 50 different random samples collected from the population of fetal fibroblast cells, that had been labelled with YO-PRO-1 dye, it was found that a relatively high proportion of donor cells revealed ultrastructural apoptotic changes. The percentage of late apoptotic cells with advanced morphological transformations was about 40% of the total pool of the fibroblast cells. A total of 262/270 (97.0%) enucleated oocytes were subjected to reconstruction and 141/262 (53.8%) were successfully fused with non-apoptotic nuclear donor cells. Following the simultaneous fusion/activation protocol, reconstituted oocytes were selected for in vitro culture. Out of 262, 133 (50.8%) cultured NT embryos cleaved. The frequencies of cloned embryos that reached the morula and blastocyst stages were 48/133 (36.0%) and 10/133 (7.5%), respectively. In conclusion, morphology is a sufficient selection factor for detection of apoptosis in the cultured (confluent) fetal fibroblast cells to be used for cloning. Moreover, it was found that YO-PRO-1 fluorochrome may be not able to detect the early phases of apoptosis, because only the morphologically abnormal cells emitted the YO-PRO-1-derived fluorescence. This research was supported by the State Committee for Scientific Research as a Solicited Project number PBZ-KBN-084/P06/2002/4.2 from years 2003 to 2005.

Learning from Nature: Biologically-inspired Sensors (2008)

New emerging sensing applications demand novel sensors in micro-/nano-scale to enable integration and embedding into higher level structures or systems. Downsizing the structure will usually decrease the sensitivity of the sensors, since the sensitivity is a function of geometrical parameters, e.g. mass in the case of inertial sensing, and absorbing surface area in the case of an infrared sensor. To maintain a detectable readout signal for the processing electronics, new transducing mechanisms have to be devised for micro- and nano-scale sensors. Nature, especially from insects of the animal kingdom, can provide an inspiration source for the development of such novel miniaturised sensors. This thesis describes the design, analysis through simulation, fabrication, and characterisation of several examples of novel sensors inspired from natural physical sensors found in insects. The thesis serves two purposes, first, to elucidate the working mechanisms of several natural biological sensors by a combination of synthesis and analysis, and second, to implement similar working mechanisms in artificial engineering material and structure for novel sensors development. After reviewing physical sensors found in nature, and existing bio-inspired sensor developments, three cases of novel bioinspired sensors development are given. The first case is the development of a biomimetic strain sensor, inspired from the Campaniform sensillum found in insects. The second case presented is the development of a biomimetic gyroscope, inspired from the haltere found in the fly. The last case presented is the feasibility study on the development of biomimetic far infrared sensor, inspired from the biological infrared sensor found in the beetle, Melanophila acuminate. The field of applications of new transduction mechanisms inspired from biological sensors to novel ultraminiaturised sensors is very wide. Ultraminiaturised strain sensors that can be integrated into mechanical structures could provide smart structures for buildings, cars, airplanes, and robots. Novel ultraminiaturised gyroscopes could find their application in hand-held devices for personal navigation, as well as for man-machine interface. Novel ultraminiaturised infrared sensor which can be fabricated using standard CMOS technology could find its application in civilian night vision application, such as pedestrian detection in cars, and civilian security night surveillance camera.

Development of Precision DC High-Voltage Dividers (2011)

Precision dc voltage dividers with ratings of up to 1000 kV have been built using the 150-kV resistor modules developed at the National Measurement Institute, Australia. The structure of the 150-kV resistor module and the measurement techniques for evaluating its performance are described. The method for evaluating voltage ratio errors at voltages of up to 1000 kV is discussed. The voltage errors obtained in comparison measurements against other reference dividers and the measured voltage errors due to the leakage current in the insulation are presented. It is shown that a total voltage error of less than 5 μV/V at 150 kV and less than 100 μV/V at 1000 kV can be achieved.
