The Australian English Speech Corpus for In-Car Speech processing (2009)

The Australian in-car speech corpus is a multi-channel recording of a series of prompts from an in-car navigation task collected over a range of speakers in a variety of driving conditions. Its purpose is to provide a significant resource of speech data appropriate for investigating speech processing needs in the adverse environment of a car. Utterances spoken by 50 speakers were collected in seven different driving conditions, providing the foundation for investigation into noisy, speaker-independent speech processing. Speech recognition experiments are performed to validate the data, to provide baseline results for in-car speech recognition research, and to show that this data can improve speech recognition performance under adverse in-car conditions for Australian English when adapting from American English acoustic models.
Formation Conditions, Water‐vapor Permeability, and Solubility of Compression‐molded Whey Protein Films (2003)

ABSTRACT: Films based on whey protein isolate (WPI) were formed using compression molding. Compression molded films could be formed using 30% to 50% moisture content or glycerol content WPI at 104 °C to 160 °C for 2 min. Films made from water‐WPI mixtures were brittle and insoluble and had water‐vapor permeability values independent of starting water‐WPI mixture moisture content, molding temperature, or molding pressure. Gly‐WPI films produced at 104 °C were flexible and partially soluble. Gly‐WPI films produced at 140 °C were also flexible but nearly insoluble. Glycerol content and molding temperature and pressure had little effect on water‐vapor permeability values of Gly‐WPI films over the range of conditions studied.
AuPd Metal Nanoparticles as Probes of Nanoscale Thermal Transport in Aqueous Solution (2004)

Water- and alcohol-soluble AuPd nanoparticles have been investigated to determine the effect of the organic stabilizing group on the thermal conductance G of the particle/fluid interface. The thermal decays of tiopronin-stabilized 3−5-nm diameter AuPd alloy nanoparticles, thioalkylated ethylene glycol-stabilized 3−5-nm diameter AuPd nanoparticles, and cetyltrimethylammonium bromide-stabilized 22-nm diameter Au-core/AuPd-shell nanoparticles give thermal conductances G ≈ 100−300 MW m-2 K-1 for the particle/water interfaces, approximately an order of magnitude larger than the conductance of the interfaces between alkanethiol-terminated AuPd nanoparticles and toluene. The similar values of G for particles ranging in size from 3 to 24 nm with widely varying surface chemistry indicate that the thermal coupling between AuPd nanoparticles and water is strong regardless of the self-assembled stabilizing group.
A study on a bearingless drive of a surface permanent magnet synchronous motor (2012)

This paper is concerned with a bearingless drive of a surface permanent magnet synchronous motor (SPMSM). Traditional bearingless motors have suspension windings for generating radial forces. But the motor in this paper have no suspension winding. At first, it is shown that a traditional SPMSM can generate a radial force by currents of motor windings. Second, problems and one solution for bearingless drives with a higher speed and larger scale motor are shown. The characteristics of them are numerically clarified with the three-dimensional finite element method (3D-FEM) analysis.
Micro-optics technology development for advanced sensors (1993)

Advanced-technology-based electro-optical sensors of minimum size and weight require miniaturization of optical, electrical, and mechanical devices with an increasing trend toward integration of various components. Micro-optics technology has the potential in a number of areas to simplify optical design with improved performance. Applications of micro-optics technology for sensor subsystems include internally cooled apertures/windows, hybrid optical design, electronically controlled optical beam steering, and microscopic integration of microoptics, detectors, optical interconnects, and signal-processing layers. Typical components are spherical, aspherical, and dispersive microlenses which simultaneously focus and disperse light. Arrays of dispersive microlenses have potential applications in multicolor focal planes. We discuss the theory, analytical design programs, analog and Fresnel microlens design options, and photolithographic fabrication technologies for micro-optics. Sample results of several microlens types are reported. We also present results of laboratory evaluations of several microlens types that have been fabricated at Lockheed Research and Development Division (R and DD). The microlenses include both wideband and dispersive types, in isolation and in arrays. Different geometries are considered, including square, hexagonal, and skewed microlenses. Results of point-spread-function measurements from our unique micro-optics testbed facility are compared to design predictions.
FACTORS AFFECTING THE VISCOMETRIC METHOD FOR ESTIMATING THE SOMATIC CELL COUNT OF COW'S MILK (1971)

Three factors likely to influence results obtained with a viscometric technique for estimating the somatic cell content of cow's milk are examined, namely, reagent composition, mixing time after addition of reagent and “holding time” before determination of viscosity. Mixing time was the only factor of material signficance.
Allowing Finer Control Over Privacy Using Trust as a Benchmark (2006)

Every time a user conducts an electronic transaction over the Internet a wealth of personal information is revealed, either voluntarily or involuntarily. This causes serious breach of privacy for the user, in particular, if the personally identifying information is misused by the other users present in the network. Ideally, therefore, the user would like to have a considerable degree of control over what personal information to reveal and to whom. Researchers have proposed models to allow a user to determine what personal information to reveal while doing a transaction over the Internet. However, these models do not help the user in determining who to trust, how much to trust and why to trust them with the personal information. The models fail to address loss of privacy through the misuse of information. In this paper we propose a privacy enhancing trust model to measure the degree of confidence that a user can have in the context of preservation of her privacy during a transaction. The model considers several factor while computing trust which include a user's own experience and knowledge about the target user and feedback obtained from groups of peer users called 'trusted neighbors' and 'friends'. The proposed scheme provides a flexible and powerful approach for the secure handling of private data and offers a user considerable control over how she wishes to disseminate her personal data
Color Temperature Tunable White-Light LED Cluster with Extrahigh Color Rendering Index (2014)

The correlated color temperature (CCT) tunable white-light LED cluster with extrahigh color rendering property has been found by simulation and fabricated, which consists of three WW LEDs (CCT = 3183 K), one red LED (634.1 nm), one green LED (513.9 nm), and one blue LED (456.2 nm). The experimental results show that this cluster can realize the CCT tunable white-lights with a color rendering index (CRI) above 93, special CRI R9 for strong red above 90, average value of the special CRIs of R9 to R12 for the four saturated colors (red, yellow, green, and blue) above 83, and luminous efficacies above 70 lm/W at CCTs of 2719 K to 6497 K.
Regionally adaptive filtering for asymmetric stereoscopic video coding (2009)

In asymmetric stereoscopic video coding, one view can be coded in a lower resolution of the other. In this scenario, stereoscopic video can be compressed with only moderately increased bandwidth and complexity compared to 2D monoview video coding. The subjective quality degradation of this scenario can be negligible compared to coding two views with original resolution. The low-resolution view can be predicted from the high-resolution view to achieve higher coding efficiency. In this paper, a regionally adaptive filtering algorithm is proposed to generate a predictor of a macroblock (MB) or MB partition of the low-resolution view from the high-resolution view. Different filters are applied for different picture regions. Disparity motion matching and clustering are applied in the encoder for generation of regionally adaptive filters. Simulation results show that the proposed algorithm results in up to 27% bit-rate saving compared with methods without adaptive filtering.
High prevalence of Staphylococcus aureus cultivation and superantigen production in patients with psoriasis (2009)

The aim of this study was to evaluate the association of Staphylococcal enterotoxins (se) a through e, exfoliative toxin (et) a and b, toxin and toxic shock syndrome toxin (tst) and mecA with psoriasis. We also investigated the distribution of Staphylococcus aureus (S. aureus) in the skin and nares. Fifty consecutive patients with chronic plaque-type psoriasis and 50 sex- and age-matched healthy controls were included in this study. There was a statistical difference in cultivation of S. aureus between lesional (64%) and non-lesional skin (14%) in patients with psoriasis (p = 0.037). S. aureus was cultivated from the nares in 25 (50%) of 50 patients with psoriasis and in 17 (34%) of 50 healthy controls (p > 0.05). In psoriasis patients, 31 (96.8%) out of the 32 strains isolated from the lesional skin and 3 (42.3%) out of the 7 strains isolated from the non-lesional skin were toxigenic (p = 0.01). Isolated strains from the nares were toxigenic in 96% (24/25) for patients with psoriasis and in 41.2% (7/17) for healthy controls, respectively (p = 0.006). Patients with cultivation-positive in lesional skin had a significantly higher PASI score than patients who were cultivation-negative in lesional skin (8.28 +/- 3.97 vs. 5.89 +/- 2.98, p = 0.031). Our results confirm that S. aureus colonization and its toxigenic-strains are associated with psoriasis. According to our findings, non-classical superantigens such as methicillin resistance gene (mecA), see and etb may also be associated with psoriasis.
Design of Balanced RF Filter for Wireless Applications Using FBAR Technology (2006)

We present a balanced RF filter based on thin film bulk acoustic resonator (FBAR) technology for wireless applications, and demonstrate its usage in the Wide-Band Code Division Multiple Access (WCDMA) front-end as post-LNA filter. The filter, which consists of two lattice sections and one symmetric ladder section, provides deep rejection at stop-band, particularly at transmitter band (1920-1980 MHz), steep roll-off at pass-band edges, and excellent common mode rejection ratio (CMRR). The typical broadband rejection is better than 60 dB. The small size, low in-band insertion loss, sharp roll-off, high stop-band rejection, good temperature stability, and compatibility with semiconductor processing make this FBAR filter an ideal choice for GHz wireless applications.
In Vivo and In Vitro Analysis of Baculovirus <i>ie-2</i> Mutants (1999)

Upon transient expression in cell culture, the ie-2 gene of Autographa californica nuclear polyhedrosis virus (AcMNPV) displays three functions: trans activation of viral promoters, direct or indirect stimulation of virus origin-specific DNA replication, and arrest of the cell cycle. The ability of IE2 to trans stimulate DNA replication and coupled late gene expression is observed in a cell line derived from Spodoptera frugiperda but not in a cell line derived from Trichoplusia ni. This finding suggested that IE-2 may exert cell line-specific or host-specific effects. To examine the role of ie-2 in the context of infection and its possible influence on the host range, we constructed recombinants of AcMNPV containing deletions of different functional regions within ie-2 and characterized them in cell lines and larvae of S. frugiperda and T. ni. The ie-2 mutant viruses exhibited delays in viral DNA synthesis, late gene expression, budded virus production, and occlusion body formation in SF-21 cells but not in TN-5B1-4 cells. In TN-5B1-4 cells, the ie-2 mutants produced more budded virus and fewer occlusion bodies but the infection proceeded without delay. Examination of the effects of ie-2 and the respective mutants on immediate-early viral promoters in transient expression assays revealed striking differences in the relative levels of expression and differences in responses to ie-2 and its mutant forms in different cell lines. In T. ni and S. frugiperda larvae, the infectivities of the occluded form of ie-2 mutant viruses by the normal oral route of infection was 100- and 1,000-fold lower, respectively, than that of wild-type AcMNPV. The reduction in oral infectivity was traced to the absence of virions within the occlusion bodies. The infectivity of the budded form of ie-2 mutants by hemocoelic injection was similar to that of wild-type virus in both species. Thus, ie-2 mutants are viable but exhibit cell line-specific effects on temporal regulation of the infection process. Due to its effect on virion occlusion, mutants of IE-2 were essentially noninfectious by the normal route of infection in both species tested. However, since budded viruses exhibited normal infectivity upon hemocoelic injection, we conclude that ie-2 does not affect host range per se. The possibility that IE-2 exerts tissue-specific effects has not been ruled out.
First Syntheses of Caerulomycin E and Collismycins A and C. A New Synthesis of Caerulomycin A (1998)

Caerulomycins produced by Streptomyces caeruleus, and collismycins more recently isolated from Streptomyces species, are bipyridinic molecules endowed with antibiotic and cytotoxic activities. The first syntheses of caerulomycin E (1), as well as new syntheses of caerulomycin A (2), are reported. Methodologies involving efficiently controlled reactions such as metalation and cross-coupling reactions have been developed from 2,2‘-bipyridine. The functionalization at C-6 could be achieved by metalation of 2,2‘-bipyridine N-oxides 5 and 12. 6-Halo-4-methoxy-2,2‘-bipyridines (6, 10, 11) became key-molecules of these different pathways, and further functionalization at C-5 allowed the first syntheses of collismycins A (3) and C (4).
<i>SDH5</i> , a Gene Required for Flavination of Succinate Dehydrogenase, Is Mutated in Paraganglioma (2009)

Mammalian mitochondria contain about 1100 proteins, nearly 300 of which are uncharacterized. Given the well-established role of mitochondrial defects in human disease, functional characterization of these proteins may shed new light on disease mechanisms. Starting with yeast as a model system, we investigated an uncharacterized but highly conserved mitochondrial protein (named here Sdh5). Both yeast and human Sdh5 interact with the catalytic subunit of the succinate dehydrogenase (SDH) complex, a component of both the electron transport chain and the tricarboxylic acid cycle. Sdh5 is required for SDH-dependent respiration and for Sdh1 flavination (incorporation of the flavin adenine dinucleotide cofactor). Germline loss-of-function mutations in the human SDH5 gene, located on chromosome 11q13.1, segregate with disease in a family with hereditary paraganglioma, a neuroendocrine tumor previously linked to mutations in genes encoding SDH subunits. Thus, a mitochondrial proteomics analysis in yeast has led to the discovery of a human tumor susceptibility gene.

Time windows: an approach to automated abstraction of continuous-time models into discrete-event models (2002)

The automated generation of time windows from continuous system simulation models is described. Time windows can be used to automatically generate equivalent discrete-event models at a coarser granularity level and they are also instrumental to the design of event-based control systems. The generation of time windows represents one facility in the knowledge-based multifaceted modeling and simulation environment DEVS/Scheme. In this environment, continuous-time and discrete-event models can coexist, and they can be amalgamated with AI techniques. The usefulness of these concepts is demonstrated by means of a model of a robot controlled fluid handling laboratory for space station Freedom to be used for research in life sciences, microgravity sciences and space medicine.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Reliability assessment of a high performance flip-chip BGA package (organic substrate based) using finite element analysis (2004)

The continuous rise in performance requirements of highend computers and networks has resulted in a rise in demand for high pin count and more sophisticated thermal solutions. Flip chip technology naturally presents a good option in offering I/Os of more than 500. With the addition of a heat spreader (of either one-piece or two-piece lid), the thermal performance of the package can be improved tremendously. However due to the differences in material type for one-piece and two-piece designs, the mismatch in thermal expansion between substrate and lid has constituted to different stress distributions in the package. In the current work, finite element simulation was used to perform structural analysis and comparison between the two different designs. Results showed that the two-piece design generated a lower package warpage, thus allowing better surface mounting. On the other hand, the one-piece lid constituted to lower package induced stresses. The increase in lid width improves package performance in terms of warpage and heat spreader to substrate interfacial shear stresses. Solder joint reliability for the one-piece design was evaluated using Darveaux’s volume weighted average viscoplastic strain energy approach. To account for the effect of ramp rate and frequency effects of a temperature cycle, frequency-modified low cycle fatigue relationship developed by Shi et al was employed for comparison with Darveaux’s computation. Lastly, parametric effects of lid material, bond pad structure, die size, substrate and PCB thickness on solder joints reliability have been documented. The trends presented would be useful for both the package and board level reliability assessments and containing possible solder joint failures.

Automation and Optimisation of Centrifuge Sludge Dewatering (1989)

The dehydration of sewage treatment plant sludges has become one of the major problems in the treatment of waste Water. Very high costs, especially those of flocculation additives, increasingly call for optimisation of this phase of the process. Taking the dewatering of sludge by centrifugation as an example, two different approaches can be considered: mechanical excess sludge thickening without the use of additives and the dehydration of sewage sludge with use of chemical additives. A prerequisite of any automation is the reliable acquisition of data of the parameters required for control. Continuous measurement of the concentration of suspended solids in the sludge that is to be dewatered, of sludge flow and of the turbidity of the clear phase (centrate) leaving the centrifuge, make it possible to design several methods of effective control.
A Secure Data Sharing Platform Using Blockchain and Interplanetary File System (2019)

In a research community, data sharing is an essential step to gain maximum knowledge from the prior work. Existing data sharing platforms depend on trusted third party (TTP). Due to the involvement of TTP, such systems lack trust, transparency, security, and immutability. To overcome these issues, this paper proposed a blockchain-based secure data sharing platform by leveraging the benefits of interplanetary file system (IPFS). A meta data is uploaded to IPFS server by owner and then divided into n secret shares. The proposed scheme achieves security and access control by executing the access roles written in smart contract by owner. Users are first authenticated through RSA signatures and then submit the requested amount as a price of digital content. After the successful delivery of data, the user is encouraged to register the reviews about data. These reviews are validated through Watson analyzer to filter out the fake reviews. The customers registering valid reviews are given incentives. In this way, maximum reviews are submitted against every file. In this scenario, decentralized storage, Ethereum blockchain, encryption, and incentive mechanism are combined. To implement the proposed scenario, smart contracts are written in solidity and deployed on local Ethereum test network. The proposed scheme achieves transparency, security, access control, authenticity of owner, and quality of data. In simulation results, an analysis is performed on gas consumption and actual cost required in terms of USD, so that a good price estimate can be done while deploying the implemented scenario in real set-up. Moreover, computational time for different encryption schemes are plotted to represent the performance of implemented scheme, which is shamir secret sharing (SSS). Results show that SSS shows the least computational time as compared to advanced encryption standard (AES) 128 and 256.
Human serum catalase decreases endothelial cell injury from hydrogen peroxide (1991)

Serum from normal human subjects contained variable amounts of catalase activity, which was inhibitable by heat, azide, trichloroacetic acid (TCA), or aminotriazole treatment. Serum also decreased hydrogen peroxide (H2O2) concentrations in vitro and H2O2-mediated injury to cultured endothelial cells. By comparison, heat-, azide-, TCA-, or aminotriazole-treated serum neither decreased H2O2 concentrations in vitro nor reduced H2O2-mediated damage to endothelial cells. We conclude that serum catalase activity can alter H2O2-dependent reactions. We speculate that variations in serum catalase activity may alter individual susceptibility to oxidant-mediated vascular disease or be a factor when added to test systems in vitro.
