Application of Diagnostic Algorithms for Maintenance Optimization of Marine Gas Turbines (2002)

As part of the Naval gas turbine CBM effort, diagnostic and prognostic algorithms that utilize state-of-the-art probabilistic modeling and analysis technologies are being developed and implemented onboard Navy ships. The algorithms under development and testing will enhance gas turbine preventative maintenance in such areas as compressor on-line/crank wash and fuel nozzle replacement. In one application, the prognostic module assesses and predicts compressor performance degradation due to salt ingestion. From this information, the optimum time for on-line water washing or crank washing can be determined from a cost/benefit standpoint. A second application diagnoses the severity of fuel nozzle fouling in real-time during startup. This paper discusses the diagnostic and prognostic modeling approaches to these maintenance issues and their implementation for an Allison 501-K34 gas turbine engine onboard a DDG 51 class guided missile destroyer.
The design of a task parallel library (2009)

The Task Parallel Library (TPL) is a library for .NET that makes it easy to take advantage of potential parallelism in a program. The library relies heavily on generics and delegate expressions to provide custom control structures expressing structured parallelism such as map-reduce in user programs. The library implementation is built around the notion of a task as a finite CPU-bound computation. To capture the ubiquitous apply-to-all pattern the library also introduces the novel concept of a replicable task. Tasks and replicable tasks are assigned to threads using work stealing techniques, but unlike traditional implementations based on the THE protocol, the library uses a novel data structure called a 'duplicating queue'. A surprising feature of duplicating queues is that they have sequentially inconsistent behavior on architectures with weak memory models, but capture this non-determinism in a benign way by sometimes duplicating elements. TPL ships as part of the Microsoft Parallel Extensions for the .NET framework 4.0, and forms the foundation of Parallel LINQ queries (however, note that the productized TPL library may differ in significant ways from the basic design described in this article).

7-Bit/2Cell (X3.5), 9-Bit/2Cell (X4.5) NAND Flash Memory: Half Bit technology (2023)

In this work, a 3. 5bit/cell (X3.5) flash memory is introduced to achieve a lower giga-byte cost with high reliability and performance. Accordingly, 7-bit data are stored in two memory cells with 12-level Vth distributions. The X3.5 Programming method does not require the complex approach used in QLC and can easily be handled by NAND controller. QLC needs a more powerful ECC than TLC; hence, increasing the size of the ECC parity for QLC enlarges the die size. However, the same ECC parity size as TLC can be applicable to X3.5. An X3.5 die size with a TLC ECC is only 6.3% bigger than QLC. By contrast, X3.5 Program performance is 2.3 times faster than QLC with the QLC reliability criteria, which is relaxed from the TLC reliability criteria. If the size of the ECC parity is reduced to that of 32nmMLC, X3.5 die size will be close to that of QLC, while X3.5 Program performance will be 1.6 times faster than that of QLC. Moreover, X3.5 will meet the TLC reliability criteria. In addition to expanding X3.5 technologies, 4.5 bit/cell (X4.5) with a 24-level Vth distributions is also possible, which is suitable for cold storage applications.
Graphene-Based Transparent Conducting Substrates for GaN/AlGaN Nanocolumn Flip-Chip Ultraviolet Light-Emitting Diodes (2021)

Flip-chip ultraviolet light-emitting diodes based on self-assembled GaN/AlGaN nanocolumns have been fabricated, exploiting single-layer graphene not only as a growth substrate but also as a transparent conducting electrode. High crystalline quality of the nanocolumns is confirmed by detailed electron microscopy characterization, also showing the intrinsic GaN quantum disk in the active region of the nanocolumns. These features are further confirmed in the optical emission, where the absence of defect-related yellow emission and the presence of blue-shifted (from the usual 365 nm band gap emission of bulk wurtzite GaN) emission at ∼350 nm, ascribed to quantum confinement and strain effects, are observed. Despite a noticeable graphene damage after the nanocolumn growth that causes high sheet resistance of graphene and high turn-on voltage, the proof of concept of single-layer graphene used as the transparent conducting substrate for a nanocolumn device is demonstrated. This study offers an alternative platform for the fabrication of next-generation nano-optoelectronic and electronic devices.

Safe TNF-based antitumor therapy following p55TNFR reduction in intestinal epithelium (2013)

TNF has remarkable antitumor activities; however, therapeutic applications have not been possible because of the systemic and lethal proinflammatory effects induced by TNF. Both the antitumor and inflammatory effects of TNF are mediated by the TNF receptor p55 (p55TNFR) (encoded by the Tnfrsf1a gene). The antitumor effect stems from an induction of cell death in tumor endothelium, but the cell type that initiates the lethal inflammatory cascade has been unclear. Using conditional Tnfrsf1a knockout or reactivation mice, we found that the expression level of p55TNFR in intestinal epithelial cells (IECs) is a crucial determinant in TNF-induced lethal inflammation. Remarkably, tumor endothelium and IECs exhibited differential sensitivities to TNF when p55TNFR levels were reduced. Tumor-bearing Tnfrsf1a⁺⁺/⁻ or IEC-specific p55TNFR-deficient mice showed resistance to TNF-induced lethality, while the tumor endothelium remained fully responsive to TNF-induced apoptosis and tumors regressed. We demonstrate proof of principle for clinical application of this approach using neutralizing anti-human p55TNFR antibodies in human TNFRSF1A knockin mice. Our results uncover an important cellular basis of TNF toxicity and reveal that IEC-specific or systemic reduction of p55TNFR mitigates TNF toxicity without loss of antitumor efficacy.

Ciliary Beat Frequency of Middle Ear, Eustachian Tube and Other Upper Respiratory Tract in Mice (1999)

Background and Objectives:The aim of this study is to analyze ciliary beat frequency (CBF and ciliary morphology of the middle ear bulla and the upper respiratory tract in mice. Materials and Methods:Fifteen mice with 37-42 gram weight were dissected and specimens were taken from the middle ear bulla, the eustachian tube, the inferior turbinate, the nasopharynx, and the upper trachea. The CBF of each specimen was measured using a video-computerrized analysis system and themorphology of cilia was also studied using scanning electron microscopy (SEM. Results:The measured CBF ranged from 9.38 Hz to 13.59 Hz, and there were no significant differences in the CBF values among the middle ear bulla, the eustachian tube, the inferior turbinate and the nasopharynx, except for the upper trachea. The mean CBF value of the upper trachea was 11.6 Hz, which was significantly lower than those of other parts. SEM showed that the cilia of the upper tracheal region were shorter than those of other parts. Conclusion:The CBF value of the middle ear bulla is similar to those of other parts in the upper respiratory tract except for the upper trachea. In the upper trachea, the CBF is lower and ciliary lenghth of epithelium is shorter than those of other parts. (Korean J Otolaryngol 1999;42:1093-7
Separation of Čerenkov radiation in irradiated optical fibers by optical spectroscopy (2015)

We studied Čerenkov radiation generated in irradiated optical fibers and demonstrated a generic spectroscopic method for separation of Čerenkov radiation from the transmitted signal in fiber optic dosimetry based on the assumption that the recorded signal is a linear superposition of two basis spectra: Čerenkov radiation and characteristic luminescence of the phosphor medium. Experimentally, we evaluated this technique by using fiber optic probes irradiated by electron beams generated by a clinical linear accelerator. This method can be used for optical characterization of various scintillating materials, such as phosphor nanoparticles, in ionizing radiation fields of high energy. We performed Monte Carlo simulations of the Čerenkov radiation generated in the fiber and found a strong dependence of the recorded Čerenkov radiation on the numerical aperture of the fiber at shallow phantom depths; however, beyond the depth of maximum dose that dependency is minimal. Our simulation results agree well with the experimental results for Čerenkov radiation generated in fibers irradiated with 6 MeV electrons.
Characterization of Transients. (1995)

Abstract : We introduced a signal representations to defect and analyze transients. A new algorithm called matching pursuit was developed to decompense any signal as a sum of waveforms that are chosen adaptively from a redundant dictionary of patterns, in order to best match the signal structures. This algorithm was applied to dictionary of dilated Gabor functions in order to characterize oscillatory transients of various sizes and frequencies. The asymptotic properties of this algorithm have been analyzed and we proved the existence of an attractor. This led to a general noise removal procedure which has been applied to audio signals. A fast matching pursuit algorithm was also designed and implemented in a software that is freely available on the internet. The matching pursuit algorithm has been extended in two dimensions for image processing. The image dictionary is composed of translated, dilated, and rotated wavelets. Applications to texture discrimination have been studied. To isolate patterns whose support may intersect, we have introduced a high resolution pursuit algorithm which was used to decompose high resolution radar signals.
DESIGN AND IMPLEMENTATION OF THE WHITE CIRCUIT BYPASS CAPACITOR PROTECTION SYSTEM (2002)

To meet high performance 1.5GeV injection requirement, the white circuit system of the booster synchrotron in SRRC must be working in accordance with the 1.5GeV injection current state. If the booster operation current of the white circuit system deviates from the normal working point too much, the injection efficiency will be deteriorated and the white circuit bypass capacitor will be damaged. A protection system of the booster white circuit bypass capacitor dynamic current and voltage must be monitored and detected to prevent this capacitor from being damaged. The new white circuit bypass capacitor protection system was designed to detect the bypass capacitors dynamic characteristic. The interlock protection is active when the bypass capacitors work in over current or voltage reverse state, and afterward the white circuit bypass capacitor protection function is achieved. Results and working function will be presented in this paper. 1

Coherent collocated MIMO radar demonstration for air defence applications (2013)

Coherent collocated MIMO radar is an emerging technology from which is expected several benefits since digital and adaptive beamforming are available at both transmit and receive sides. A large number of papers are dealing with theoretical analysis of those benefits. Nevertheless, few experimental performance assessments of those benefits have been reported. During the last few years, ONERA has built a powerful and versatile surface radar testbed named HYCAM. Its design included a MIMO mode in order to test the different classes of waveforms in real conditions (hardware defaults, clutter characteristics) which can hardly be modeled with accuracy. After a recall of the MIMO processing principles, this paper sums up the benefits and drawbacks that are expected from this technology and the need of experimentation to verify those expectations. Then we will present ONERA's HYCAM MIMO testbed and first results of MIMO trials using this system as well. Those experimental results will be linked to a more general discussion on impacts of hardware defaults on MIMO radar waveforms performances.
Hypogonadism in patients treated with intrathecal morphine. (Perth Pain Medicine Center, South Perth, Western Australia) Clin J Pain 2000;16:251–254. (2001)

This study investigated the hypothalamic‐pituitary‐gonadal response to intrathecal opioids. Thirty patients receiving intrathecal morphine for chronic nonmalignant pain were studied for clinical and biochemical evidence of hypogonadism. Ten men and 10 postmenopausal women with chronic pain of similar duration but were not receiving any form of opioid therapy acted as control subjects. Men and both premenopausal and postmenopausal women had evidence of hypogonadism with low levels of serum testosterone or estrogen coupled with low levels of pituitary gonadotrophins. Control subjects had hormone levels in the expected range for their sex and age. Two men demonstrated recovery after ceasing intrathecal opioid therapy. Conclude that hypogonadotrophic hypogonadism is a common complication of intrathecal opioid therapy in both men and women.

High Resolution Electrodes Fabrication for OTFT by using Microcontact Printing Process (2006)

The organic thin film transistor (OTFT) array to use as a switching device for an organic light emitting diode (OLED) was designed and fabricated in the microcontact printing and room temperature process. The gate, source, and drain electrode patterns of OTFT were fabricated by microcontact printing process. The OTFT array with dielectric layer and organic active semiconductor layer formed at room temperature or at a temperature lower than 40 &#xB0;C. The microcontact printing process using SAM and PDMS stamp made it possible to fabricate OTFT arrays with channel lengths down to even submicron size, and reduced the fabrication process by 10 steps compared with photolithography. Since the process was done in room temperature, there was no pattern shrinkage, transformation, and bending problem appeared. Also, it was possible to improve electric field mobility, to decrease contact resistance, to increase close packing of molecules by SAM, and to reduce threshold voltage by using a big dielectric.
Birefringence compensated cylindrical piezoelectric fibre phase modulator (1996)

Abstract A method is demonstrated for compensating birefringence effects in nominally circular-core fibre wound onto piezoelectric cylinders designed for use as phase modulators. Two fibre-wound piezoelectric cylinders are used, with the fast axis of one aligned with the slow axis of the other using a bulk-optic half waveplate. It is shown that, compared with a single element modulator, the compensation achieved is necessary and more than sufficient if used as a phase modulator in a fibre stellar interferometer.

Functionalized Graphene Sheets as a Versatile Replacement for Platinum in Dye-Sensitized Solar Cells (2012)

Several techniques for fabricating functionalized graphene sheet (FGS) electrodes were tested for catalytic performance in dye-sensitized solar cells (DSSCs). By using ethyl cellulose as a sacrificial binder, and partially thermolyzing it, we were able to create electrodes which exhibited lower effective charge transfer resistance (<1 Ω cm(2)) than the thermally decomposed chloroplatinic acid electrodes traditionally used. This performance was achieved not only for the triiodide/iodide redox couple, but also for the two other major redox mediators used in DSSCs, based on cobalt and sulfur complexes, showing the versatility of the electrode. DSSCs using these FGS electrodes had efficiencies (η) equal to or higher than those using thermally decomposed chloroplatinic acid electrodes in each of the three major redox mediators: I (η(FGS) = 6.8%, η(Pt) = 6.8%), Co (4.5%, 4.4%), S (3.5%, 2.0%). Through an analysis of the thermolysis of the binder and composite material, we determined that the high surface area of an electrode, as determined by nitrogen adsorption, is consistent with but not sufficient for high performing electrodes. Two other important considerations are that (i) enough residue remains in the composite to maintain structural stability and prevent restacking of FGSs upon the introduction of the solvent, and (ii) this residue must not disperse in the electrolyte.
Molecular imaging of membrane proteins and microfilaments using atomic force microscopy (2010)

Atomic force microscopy (AFM) is an emerging technique for a variety of uses involving the analysis of cells. AFM is widely applied to obtain information about both cellular structural and subcellular events. In particular, a variety of investigations into membrane proteins and microfilaments were performed with AFM. Here, we introduce applications of AFM to molecular imaging of membrane proteins, and various approaches for observation and identification of intracellular microfilaments at the molecular level. These approaches can contribute to many applications of AFM in cell imaging.

Modeling and Analysis of AC Output Power Factor for Wireless Chargers in Electric Vehicles (2016)

This paper presents a general mathematical expression and characteristic analysis of the output power factor before rectification on the receiver side for wireless chargers in electric vehicles. This power factor is usually regarded as unity (i.e., the ac output voltage is in phase with the current), based on fundamental harmonic approximation. However, the default unity power factor assumption is not accurate for output power derivation even at resonance frequency. This study explores not only output power factor characteristics for different frequencies or power levels, but also the phase relationships of the input and output ac voltages. The continuous conduction mode and discontinuous conduction mode are both analyzed. An integrated LCC compensation topology is selected as the research object, and its analysis process can be readily extended to other common topologies. Furthermore, this study is beneficial for the implementation of some control strategies requiring precise power computation/estimation, e.g., feedforward control or model prediction control. Finally, a comparison of numerical and experimental results with various misalignment cases validates correctness of the proposed theoretical derivation and analysis methodology.
Integrated electrical machines and drives: An overview (2015)

This paper will provide a thorough survey of both commercial products as well as what is available in literature in terms of integrated electrical machines and drives. The paper will cover a wide range of applications highlighting the advantages and challenges of achieving such integration. The paper will also highlight the current research trends.
Smart Chemical Sensor Systems for Fire Detection and Environmental Monitoring in Spacecraft (2010)

A fire in a spacecraft or habitat supporting NASA’s exploration mission could jeopardize the system, mission, and/or crew. Further, an understanding of the environment during standard operations as well as after a fire is important for both astronaut health and for monitoring of hazardous conditions. This paper describes the status of gaseous sensors to provide early warning of fires, eliminate false alarms, and provide environmental information. These gaseous sensors are miniaturized arrays of smart chemical sensors that accurately detect fire signature gases such as carbon monoxide and carbon dioxide, as well as other species such as oxygen. The approach we take can significantly reduce the size, mass, and power consumption of sensing technology allowing more strategic placement, extended operation, and improving overall awareness of the environment. In particular, this paper describes: 1) Maturation of the core chemical sensor technology and associated smart hardware; 2) Expansion of the sensor array for species of interest such as hydrogen cyanide and hydrogen chloride; and 3) Sensor system test results for two application environments. It is concluded that smart, multiparameter, microsensor based systems can serve as multiuse technology for a range of applications including fire detection and environmental monitoring, and can complement other sensor technologies.
