Using phone and diphone based acoustic models for voice conversion: a step towards creating voice fonts (2003)

Voice conversion techniques attempt to modify speech signal so that it is perceived as if spoken by another speaker, different from the original speaker. In this paper, we present a novel approach to perform voice conversion. Our approach uses acoustic models based on units of speech, like phones and diphones, for voice conversion. These models can be computed and used independently for a given speaker without being concerned about the source or target speaker. It avoids the use of a parallel speech corpus in the voices of source and target speakers. It is shown that by using the proposed approach, voice fonts can be created and stored which will represent individual characteristics of a particular speaker, to be used for customization of synthetic speech. We also show through objective and subjective tests, that voice conversion quality is comparable to other approaches that require a parallel speech corpus.

An NMOS comparator designed for a bubble memory peripheral support chip will be reported. Circuit compares the difference between two successive differential input signals against a 2.5mV threshold voltage. A 40μV offset voltage with a 0.1μV/°C drift has been measured.
An Intelligent Method for Inferring Information about the User/ Client (2001)

Having in mind today's growth of information sources, both in terms of their number and of their size, whether we are referring to the Internet, a corporate intranet, or a library information retrieval system, we can say that manipulating information is not a trivial task. The user is not often being catered for in distributed information systems. He/ she seems to be interacting with systems that do not recognize his/her uniqueness and thus do not offer an individualized treatment. As a result, User Modeling is a core, essential factor in achieving personalization. We present here an intelligent way of inferring user related information that is not available, a situation that is very likely to occur due to sparseness of relevant data. This method can be very useful in recommender systems and this is illustrated with an example.
A randomised cross-over trial in healthy adults indicating improved absorption of omega-3 fatty acids by pre-emulsification (2007)

Pre-emulsification of an oil mixture prior to ingestion increases the absorption of longer chain more highly unsaturated fatty acids (especially eicosapentaenoic acid and docosahexaenoic acid) but does not affect absorption of shorter chain less saturated fatty acids, suggesting that pre-emulsification of fish oils may be a useful means of boosting absorption of these beneficial fatty acids.
Chirp images in 2-D fractional Fourier transform domain (2016)

Chirp signals are very common in radar, communication, sonar, and etc. Little is known about chirp images, i.e., 2-D chirp signals. In fact, such images frequently appear in optics and medical science. Newton's rings fringe pattern is a classical example of the images, which is widely used in optical metrology. It is known that the fractional Fourier transform(FRFT) is a convenient method for processing chirp signals. Furthermore, it can be extended to 2-D fractional Fourier transform for processing 2-D chirp signals. It is interesting to observe the chirp images in the 2-D fractional Fourier transform domain and extract some physical parameters hidden in the images. Besides that, in the FRFT domain, it is easy to separate the 2-D chirp signal from other signals to obtain the desired image.
Homoserine Kinase from <i>Escherichia coli</i> K-12: Properties, Inhibition by <scp>l</scp> -Threonine, and Regulation of Biosynthesis (1974)

We have partially purified homoserine kinase from a genetically derepressed strain of Escherichia coli K-12. The optimum pH of the enzyme-substrate reaction was 7.8 and the K(m) values for l-homoserine and adenosine 5'-triphosphate were both 3 x 10(-4) M. K(+) (or NH(4) (+)) as well as Mg(2+) were required for its activity. The sedimentation coefficient determined by ultracentrifugation in a sucrose density gradient was 5.0 +/- 0.25S. l-Homoserine was an excellent protector against heat inactivation of homoserine kinase. l-Threonine was a competitive inhibitor of homoserine kinase, suggesting that end-product inhibition of this enzyme plays a role in vivo in the overall regulation of threonine biosynthesis. The specific activity of aspartokinase I-homoserine dehydrogenase I and of homoserine kinase showed a strong positive correlation in extracts from strains under widely varying conditions of genetic or physiological derepression; it was concluded that these two enzymes are coordinately regulated in E. coli K-12.
Purification of α-L-Fucosidase from the Liver of a Marine Gastropod, Charonia lampas (1971)

Using p-nitrophenyl α-L-fucoside as substrate, α-L-fucosidase was purified by about 120 fold from the liver extract of Charonia lampas by the combination of ammonium sulfate factionation, pH 4 treatment, heating, Sephadex G-200 column chromatography and hydroxylapatite column chromatography. The purified enzyme was practically free from all other glycosidases tested, when examined with aryl glycosides as substrate, was inhibited by PCMB, and had pH optimum at 3.3. The Michaelis constant toward p-nitrophenyl α-L-fucoside was 3.1×10−4M.
Analysis of mode partition noise in laser transmission systems (1982)

Mode partition noise can be the dominant limitation on a system error rate for single-mode-fiber laser transmission systems. The distribution of power among the longitudinal modes of the laser fluctuates and, as a consequence of chromatic dispersion in the fiber, causes an amplitude fluctuation of the signal at the decision circuit in the receiver. The effect is in essence a pulse-delay fluctuation, and the error rate cannot be reduced by increasing the received signal power. We derive a simple formula describing this mode partition noise, give useful design relations, and verify the analysis by comparison with system experiments.
A Case History of Sustainable Annulus Pressure in Sour Wells – Prevention, Evaluation and Remediation (2005)

Summary This paper describes evaluation of the possible causes of Sustainable Annular Pressure (SAP) in a sour gas field in the Middle East. It explains the diagnostic testing undertaken and describes how evidence was used to identify the cause of the SAP. The steps taken to prevent the occurrence of SAP in new wells and to remedy the problem in existing wells are described. This practical approach, based on critical assessment of many aspects of the whole well condition put the SAP problem under total control, covering the process from well design through the lifecycle of the well. This all-encompassing approach is regarded to be essential for all sour gas wells, but especially for HPHT designs.
La implantación de sistemas informativos de gestión en la empresa constructora: reflexiones en torno a la delimitación de los agentes que operan en el sector y principales características y peculiaridades de su actividad (2001)

La gestion empresarial exige el desarrollo de sistemas informativos capaces de suministrar la informacion adecuada que sirva de apoyo a procesos de toma de decisiones orientados por criterios de racionalidad economica. Tal circunstancia adquiere una importancia critica en el caso de la empresa constructora que, por sus especiales caracteristicas, requiere especial atencion respecto a una actividad planificadora que garantice la consecucion de excedentes empresariales. En el presente trabajo pretendemos, como primer eslabon para el analisis de los modelos de gestion que les sean de mayor utilidad, efectuar algunas reflexiones sobre la oportuna delimitacion de los agentes que participan en dicha industria, cuya diversa fenomenologia obliga a una rigurosa demarcacion de la problematica propia de cada objeto de estudio.
Erosion Testing of Thermal Barrier Coatings in a High Enthalpy Wind Tunnel (2014)

One of the major problems facing the users of aircraft engines and stationary gas turbines in dusty and dirty environments is erosion, causing engine performance deterioration. Thermal barrier coatings (TBCs) are often applied on metal engine components as combustor heat shields or tiles as well as turbine blades allowing enhanced operating temperatures and resulting in increased thermal efficiency of the turbine and also reduced fuel consumption and gaseous emission. Erosive attack by airborne dust or fly ash, coarse particles causes coating degradation resulting in lifting issues of engine components. In the present study, an erosion test facility was used to simulate the mechanisms of coating degradation expected in gas turbines in a more realistic way closer to real engine conditions. A loading situation combining thermal gradient cycling and erosive media was used. The experiments have been performed with an arc heated plasma wind tunnel (PWT total enthalpy up to 20 MJ/kg), which is available at the Institute for Thermodynamics at the University of the Federal Armed Forces in Munich, Germany. The experimental setup and the integration of the air jet erosion test rig into the existing PWT will be elucidated. Different plasma sprayed TBC materials, including the standard TBC material yttria-stabilized zirconia (YSZ), were investigated regarding their erosion resistance. For validation and verification, samples of nickel-based Mar-M 247 and INCO 718 alloys have been used.
Febrile-Range Hyperthermia Augments Neutrophil Accumulation and Enhances Lung Injury in Experimental Gram-Negative Bacterial Pneumonia (2005)

We previously demonstrated that exposure to febrile-range hyperthermia (FRH) accelerates pathogen clearance and increases survival in murine experimental Klebsiella pneumoniae peritonitis. However, FRH accelerates lethal lung injury in a mouse model of pulmonary oxygen toxicity, suggesting that the lung may be particularly susceptible to injurious effects of FRH. In the present study, we tested the hypothesis that, in contrast with the salutary effect of FRH in Gram-negative peritonitis, FRH would be detrimental in multilobar Gram-negative pneumonia. Using a conscious, temperature-clamped mouse model and intratracheal inoculation with K. pneumoniae Caroli strain, we showed that FRH tended to reduce survival despite reducing the 3 day-postinoculation pulmonary pathogen burden by 400-fold. We showed that antibiotic treatment rescued the euthermic mice, but did not reduce lethality in the FRH mice. Using an intratracheal bacterial endotoxin LPS challenge model, we found that the reduced survival in FRH-treated mice was accompanied by increased pulmonary vascular endothelial injury, enhanced pulmonary accumulation of neutrophils, increased levels of IL-1beta, MIP-2/CXCL213, GM-CSF, and KC/CXCL1 in the bronchoalveolar lavage fluid, and bronchiolar epithelial necrosis. These results suggest that FRH enhances innate host defense against infection, in part, by augmenting polymorphonuclear cell delivery to the site of infection. The ultimate effect of FRH is determined by the balance between accelerated pathogen clearance and collateral tissue injury, which is determined, in part, by the site of infection.
Parallel distributed simulation and modeling methods: an algorithm for fully-reversible optimistic parallel simulation (2003)

Typically, large-scale optimistic parallel simulations will spend 90% or more of the total execution time forward processing events and very little time executing rollbacks. In fact, it was recently shown that a large-scale TCP model consisting of over 1 million nodes will execute without generating any rollbacks (i.e., perfect optimistic execution is achieved). The major cost involved in forward execution is the preparation for a rollback in the form of state-saving. Using a technique called reverse computation, state-saving overheads can be greatly reduced. Here, the rollback operation is realized by executing previously processed events in reverse. However, events are retained until GVT sweeps past. In this paper, we define a new algorithm for realizing a continuum of reverse computation-based parallel simulation systems, which enables us to relax the computing of GVT and potentially further reduces the amount of memory required to execute an optimistic simulation.

Surface properties of hydrogenated nanodiamonds: a chemical investigation (2011)

Hydrogen terminations (C-H) confer to diamond layers specific surface properties such as a negative electron affinity and a superficial conductive layer, opening the way to specific functionalization routes. For example, efficient covalent bonding of diazonium salts or of alkene moieties can be performed on hydrogenated diamond thin films, owing to electronic exchanges at the interface. Here, we report on the chemical reactivity of fully hydrogenated High Pressure High Temperature (HPHT) nanodiamonds (H-NDs) towards such grafting, with respect to the reactivity of as-received NDs. Chemical characterizations such as FTIR, XPS analysis and Zeta potential measurements reveal a clear selectivity of such couplings on H-NDs, suggesting that C-H related surface properties remain dominant even on particles at the nanoscale. These results on hydrogenated NDs open up the route to a broad range of new functionalizations for innovative NDs applications development.
69.4: <i>Invited Paper:</i> Mass Production of Full‐Color AMOLED Displays (2005)

Abstract Mass production of full‐color active‐matrix OLED (AMOLED) displays began in October 2002 at SK Display Corporation. This milestone was achieved through an integration of modified low‐temperature polysilicon substrates (LTPS), manufacturing subsystems for the uniform deposition of OLED device structures, encapsulation subsystems with automated desiccant delivery, precision shadow masks for color pixel patterning, and the ability to meet product specifications. This paper discusses the advances made in process integration, reproducibility of display performance, productivity gains, and yield improvement. During two years of production experience, SK Display has made steady progress on its manufacturing learning curve and has already introduced second‐generation AMOLED production equipment for 335 × 550 mm glass substrates. The chosen OLED technologies are scaleable to larger glass substrate sizes compatible with existing LTPS facilities. Even though OLED deposition technologies have significantly matured in productivity, yield, and available capacity, substantial improvements in the quality of LTPS substrates suitable for OLEDs is necessary before AMOLEDs can become competitive with AMLCDs.
Periodic Leaky-Wave Antenna for Millimeter Wave Applications Based on Substrate Integrated Waveguide (2009)

Substrate integrated waveguides (SIW) are built up of periodically arranged metallic via-holes or via-slots. The leakage loss of SIW structures increases with the distance between the via-holes or via-slots. An open periodic waveguide with a large via distance supports the propagation of leaky-wave modes and can thus be used for the design of a leaky-wave antenna. In this paper, this leakage loss is studied in detail and used to design a periodic leaky-wave antenna. The proposed concept represents an excellent choice for applications in the millimeter-wave band. Due to its versatility, the finite difference frequency domain method for periodic guided-wave or leaky-wave structures is used to analyze the characteristics of the proposed periodic leaky-wave antenna. Two modes (TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> and TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">20</sub> ) are investigated and their different leaky-wave properties are analyzed. Based on the proposed leaky-mode analysis method, a novel periodic leaky-wave antenna at 28-34 GHz is designed and fabricated.
Zimbabwe, Zambia, Malawi and Tanzania : Priority Fruit Species and Products for Tree Domestication and Commercialisation (2006)

In collaboration with partners, the\n World Agro-forestry Centre established a number of fruit\n processing groups in Zimbabwe, Zambia, Malawi and Tanzania.\n These groups are actively involved in the processing of\n products such as wines and jams and sell their products in\n their respective districts. During 2003 a number of these\n groups and other stakeholders were consulted regarding the\n fruit species and products that they prefer to process, and\n other aspects such as training, marketing and general\n constraints. A total of 97 people attended three workshops\n at Magomero in Malawi, Tabora in Tanzania and Harare in\n Zimbabwe. The three workshops highlighted the differences in\n perceptions regarding fruit trees and fruit products between\n commercial and community processors, as well as between\n processors in different areas of southern Africa. Evidently,\n communities involved with the processing of fruit, prefer to\n utilize both indigenous and exotic species. In developing\n agro-forestry strategies it would be critical to consider\n these differences between processing groups. The focus\n should be on a range of tailor-made domestication and\n commercialization strategies for different processing\n groups, levels of commercial development and geographic\n regions. Such a strategy could present regional development\n agencies an opportunity to concentrate on smaller more\n focused projects instead of large regional initiatives that\n are difficult to manage.
Towards measurement of testability of concurrent object-oriented programs using fault insertion: a preliminary investigation (2003)

There is a lack of methods and techniques for measuring testability of concurrent object-oriented programs. Current theory and practice for testing sequential programs do not usually apply to concurrent systems. An approach towards measuring the testability of concurrent Java programs is proposed in this paper. The key idea is to take a program and insert faults that are related to the concurrency aspects. The approach is based on two methods: (1) mutation of the program based on keywords, and (2) creation of conflict graphs based on static analysis of the code.
<i>Abr1</i>, a Transposon-Like Element in the Genome of the Cultivated Mushroom<i>Agaricus bisporus</i>(Lange) Imbach (1999)

ABSTRACT A 300-bp repetitive element was found in the genome of the white button mushroom, Agaricus bisporus , and designated Abr1 . It is present in ∼15 copies per haploid genome in the commercial strain Horst U1. Analysis of seven copies showed 89 to 97% sequence identity. The repeat has features typical of class II transposons (i.e., terminal inverted repeats, subterminal repeats, and a target site duplication of 7 bp). The latter shows a consensus sequence. When used as probe on Southern blots, Abr1 identifies relatively little variation within traditional and present-day commercial strains, indicating that most strains are identical or have a common origin. In contrast to these cultivars, high variation is found among field-collected strains. Furthermore, a remarkable difference in copy numbers of Abr1 was found between A. bisporus isolates with a secondarily homothallic life cycle and those with a heterothallic life cycle. Abr1 is a type II transposon not previously reported in basidiomycetes and appears to be useful for the identification of strains within the species A. bisporus .
Measurement Properties of Instruments for Measuring of Lymphedema: Systematic Review (2016)

Measurement instruments with evidence for good reliability and validity were BIS, water volumetry, tape measurement, and perometry, where BIS can detect alterations in extracellular fluid in stage 1 lymphedema and the other measurement instruments can detect alterations in volume starting from stage 2. In research, water volumetry is indicated as a reference test for measuring lymphedema in the upper extremities.
Simulation and Performance Evaluation of Hydraulic Transmission Electromagnetic Energy-Regenerative Active Suspension (2010)

A new shock absorber with the combined mechanical-electromagnetic-hydraulic structure is proposed to recycle the energy dissipated by shock absorber in the process of driving. The suspension system built on the new shock absorber is generally called hydraulic transmission electromagnetic energy-regenerative suspension. This paper presents the working theories of the hydraulic transmission electromagnetic energy-regenerative suspension, and also builds a kinetics simulation model by applying the interdisciplinary soft ware AMESim. Based on the results of the simulation, the paper makes a comparison between the hydraulic transmission electromagnetic energy-regenerative suspension and the passive suspension, and the results reveal that the comprehensive performance of the former is superior to that of the latter, which proves the theoretical feasibilities of the energy-regenerative suspension of this structure to improve the ride comfort and the fuel economy.
Bronchopulmonary Dysplasia: NHLBI Workshop on the Primary Prevention of Chronic Lung Diseases (2014)

Bronchopulmonary dysplasia (BPD) is the most common complication of extreme preterm birth. Infants who develop BPD manifest aberrant or arrested pulmonary development and can experience lifelong alterations in cardiopulmonary function. Despite decades of promising research, primary prevention of BPD has proven elusive. This workshop report identifies current barriers to the conduct of primary prevention studies for BPD and causal pathways implicated in BPD pathogenesis. Throughout, we highlight promising areas for research to improve understanding of normal and aberrant lung development, distinguish BPD endotypes, and ascertain biomarkers for more targeted therapeutic approaches to prevention. We conclude with research recommendations and priorities to accelerate discovery and promote lung health in infants born preterm.
