Setting Up of a Probabilistic Neural Network for Sensor Fault Detection Including Operation With Component Faults (2002)

The diagnostic ability of Probabilistic Neural Networks (PNN) for detecting sensor faults on gas turbines is examined. The structure and the features of a PNN, for sensor fault detection, are presented. It is shown that with the proposed formulation, a powerful tool for sensor fault identification is produced. A particular feature of the PNN produced is the ability to detect sensor faults even in the presence of engine component malfunction, as well as on deteriorated engines. In such situations, the size of bias that can be identified increases. The way to establish the limits of sensor bias that can be detected is presented along with results from application to test cases with realistic noise magnitudes. The diagnostic procedure proposed here is also supported by an engine performance model. The data used for setting up and testing the PNN are generated by such a model.
Wireless Multi Hop Access Networks and Protocols (2007)

As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. It investigates how ad hoc networks can be combined with wireless and mesh networks in order to create wireless multi hop access networks. When several access points to the Internet are available, and the mobile node roams to a new access point, the node has to make a decision when and how to change its point of attachment. The thesis describes how to consider the rapid fluctuations of the wireless medium, how to handle the fact that other nodes on the path to the access point are also mobile which results in frequent link and route breaks, and the impact the change of attachment has on already existing connections. Medium access and routing protocols have been developed that consider both the long term and the short term variations of a mobile wireless network. The long term variations consider the fact that as nodes are mobile, links will frequently break and new links appear and thus the network topology map is constantly redrawn. The short term variations consider the rapid fluctuations of the wireless channel caused by mobility and multi path propagation deviations. In order to achieve diversity forwarding, protocols are presented which consider the network topology and the state of the wireless channel when decisions about forwarding need to be made. The medium access protocols are able to perform multi dimensional fast link adaptation on a per packet level with forwarding considerations. This i ncludes power, rate, code and channel adaptation. This will enable the type of performance improvements that are of significant importance for the success of multi hop wireless networks. (Less)
Cerebral Aneurysm Multicenter European Onyx (CAMEO) trial: results of a prospective observational study in 20 European centers. (2004)

In selected patients with aneurysms that are unsuitable for coil treatment or in whom previous treatment has failed to occlude the aneurysm, Onyx treatment offers an endovascular alternative. Aneurysm occlusion rates are superior to reported rates of coil occlusion, and treatment morbidity is comparable to that of published prospective data on endovascular results for this subgroup of patients.
Performance Analysis of a Completely Sealed Double Oscillating Structure Applied in Wave Energy Extraction (2013)

Most of the traditional wave energy converters are of a single oscillation structure, which leads to difficulties in sealing and installation. Based on the technological status of disc-type permanent magnetic coreless generator (DPMCLG) and long-stroke tape-type spring, a small scale wave energy extracting structure which can be completely sealed and work under the principle of double oscillation is proposed in this paper. By building a double oscillating model of the structure, the time domain differential equations and an equivalent circuit scheme are drawn, from which a phase-space solution by phase method is derived. Based on the solution, the performance of the structure is compared with that of single oscillating structure. The conclusion is that the double oscillating structure has a wider period range and higher power response for wave extraction, as well as the protection of power generator from damage in storm conditions.

<title>Qualitative approach to medical image databases</title> (1991)

The development of PACS image databases has long been thought of as a major technological challenge, due to the amount of data to be managed. On the contrary, the authors think that despite major improvements in storage technology, new data management techniques must be proposed to make image databases medically useful in PACS environments. More precisely, image databases must contain not only images per se, but also the description of all objects used in medical imaging, in order to permit the remote processing, analysis, and interpretation of images. In several other papers, the authors explain why they adopted an object-oriented approach to model information in medical imaging. In this paper, the focus is on the inventory of objects manipulated in medical imaging from a qualitative viewpoint. For this purpose, a large number of representative imaging procedures were selected. The authors characterized how they are asked for by clinicians, realized in imaging departments, and consumed by requiring physicians and surgeons, in three French university hospitals. On the basis of this inventory, a set of image data -- i.e. of objects used in medical imaging -- was defined to show that this set must evolve with advances in medical imaging, and to point out that relational DBMS concepts cannot represent all image data.
Fire Plume Behavior in Temperature-Stratified Ambients (1995)

Abstract Experiments have been conducted to establish temperature stratification conditions under which plume fluid from a fire source will or will not rise to the ceiling, and associated distributions of temperature rise and CO2 concentrations. Small fire sources of heptane were used in a pre-stratified, insulated room. A critical, nondimensional, ambient temperature rise from the source level to the ceiling is associated with plume fluid just being able to penetrate to the ceiling, which turns out to be quite insensitive to the shape of the stratification profile, although the values are considerably higher than a value derivable from previous work of Morton et al. Centerline behavior of temperature rise and CO2 concentration agreed well with the theory of these authors up to the theoretical plume reach, but the experimental values needed an incremental height, roughly equal to 25 percent of the theoretical plume reach, to return to zero.
Novel Transaminase and Laccase from Streptomyces spp. Using Combined Identification Approaches (2021)

Three Streptomyces sp. strains with a multitude of target enzymatic activities confirmed by functional screening, namely BV129, BV286 and BV333, were subjected to genome sequencing aiming at the annotation of genes of interest, in-depth bioinformatics characterization and functional expression of the biocatalysts. A whole-genome shotgun sequencing followed by de novo genome assembly and annotation was performed revealing genomes of 6.4, 9.4 and 7.3 Mbp, respectively. Functional annotation of the proteins of interest resulted in between 2047 and 2763 putative targets. Among the various enzymatic activities that the three Streptomyces strains demonstrated to produce by functional screening, we focused our attention on transaminases (TAs) and laccases due to their high biocatalytic potential. Bioinformatics search allowed the identification of a putative TA from Streptomyces sp. BV333 as a potentially novel broad substrate scope TA and a putative laccase from Streptomyces sp. BV286 as potentially novel blue multicopper oxidase. The two sequences were cloned and overexpressed in Escherichia coli and the two novel enzymes, transaminase Sbv333-TA and laccase Sbv286-LAC, were characterized. Interestingly, both enzymes resulted to be exceptionally thermostable, Sbv333-TA showing a melting temperature (TM = 85 °C) only slightly lower compared to the TM of the most thermostable transaminases described to date (87–88 °C) and Sbv286-LAC being even thermoactivated at temperature &gt;60 °C. Moreover, Sbv333-TA showed a broad substrate scope and remarkably demonstrated to be active in the transamination of β-ketoesters, which are rarely accepted by currently known TAs. On the other hand, Sbv286-LAC showed an improved activity in the presence of the cosolvent acetonitrile. Overall, it was shown that a combination of approaches from standard microbiological and biochemical screens to genome sequencing and analysis is required to afford novel and functional biocatalysts.

Changes of the Enteric Nervous System in Amyloid-β Protein Precursor Transgenic Mice Correlate with Disease Progression (2013)

In Alzheimer's disease (AD), fatal neuronal cell loss occurs long before relevant evidence can lead to a reliable diagnosis. If characteristic pathological alterations take place in the enteric nervous system (ENS), it could be one of the most promising targets for an early diagnosis, using submucosal biopsies from the gut. We therefore investigated time- and spatial-dependent changes in an amyloid-β protein precursor (AβPP) overexpressing transgenic mouse model to examine early changes within the ENS. Wholemount preparations and paraffin sections were analyzed for the expression of neuronal, glial, and innate immunity markers. Isolated myenteric networks were screened for differences in overall protein expression, and a motility analysis delivered functional data. The level of AβPP in the gut was significantly higher in the AD mouse model than in wild-type mice and also higher in the gut than in the brain at all ages investigated. The transcriptional level of Nestin, GFAP, and TLR4 increased with age with a peak at 3 months. At the protein level, human amyloid-β was located in myenteric neurons. Myenteric networks showed a reduction of the neuronal density in AβPP compared to wild-type mice, which was functionally relevant as revealed by motility analysis. The ENS undergoes significant changes during the early onset of AβPP expression in AD mouse models that appear before those seen in the brain as demonstrated in this study. Thus, there is a chance of determining similar alterations in the human gut of AD patients, which could be used to develop early diagnostic approaches.
An integrated cost model for metal cutting operations based on engagement time and a cost breakdown approach (2017)

In all manufacturing processes, it is important to determine the costs and their distribution between different sequential processing steps. A cost equation based directly on the losses during manufacturing, such as rejection rate, stops and waste of workpiece materials, also provides a valuable aid in giving priority to various development activities and investments. The present work concerns how a cost model presented earlier for calculating part costs can be developed to describe part costs as a function of the cutting data and tool life time T selected. This enables a tool life model to be a directly integrated into the cost model by use of tool engagement time. The model presented also takes into account the part costs for scrap incurred in connection with forced tool changes. Examples are also given of how the model developed can be used in the economic evaluation of various cutting tools and workpiece materials. [Received 20 April 2017; Accepted 22 April 2017]

Identification of a Muscle-specific Enhancer within the 5′-Flanking Region of the Human Myoglobin Gene (1989)

A 2-kilobase fragment from the 5'-flanking region of the human myoglobin gene extending from -2038 to +7 relative to the cap site regulates expression of a heterologous reporter gene in a cell-specific and developmentally regulated manner. Functional analyses of 5' and internal deletions indicate that sequences located between -261 and -205 are essential for muscle-specific expression in cooperation with the myoglobin core promoter. A 167-base pair fragment containing these sequences (-371 to -205) enhances expression from myoglobin core promoter elements in a manner that is independent of its orientation and position relative to the cap site. When linked to the herpes simplex virus thymidine kinase promoter, this 167-base pair fragment of the myoglobin gene also enhances expression in differentiated myotubes but not in undifferentiated myoblasts or fibroblasts. Nucleotide sequences within the region that is essential for enhancing activity (-261 to -205) are conserved in other mammalian myoglobin genes (seal, mouse) and resemble sequences within control regions of other genes that are expressed selectively in striated myocytes. These data indicate that the 5'-flanking region of the human myoglobin gene contains an enhancer-like element that is important for transcriptional activation during myocyte differentiation.
Array mapping in behavioral synthesis (1995)

Abstract: This paper discusses the mapping of arrays in a behavior to memories in an implementation. We introduce a design representation based on a variety of array grouping techniques and the binding of array groups to memory components with different dimensions, access times, and number of ports. The results of design actions are computed in terms of the number of memory components and the length of schedules in the behavior. We demonstrate the ability of a synthesis tool using this representation to generate designs that span the entire range of the memory design space.

Memory Effects In Electrophotography* (1962)

Photoconductor layers used in electrophotography exhibit more or (ess distinct memory effects when exposed to actinic light prior to the processing cycle. The memory of typical inorganic, organic and polymeric photoconductors are compared and discussed. The “ghost image” remaining after pre-exposure may be erased by application of optical, thermal or electrical energy. An electrophotographic process is described, which uses light sensitive organic substances instead of photoconductors. In contrast to known systems, exposure to light creates a persistent latent conductivity image, which cannot be destroyed by subsequent charging, heating or exposure to long wave radiation. The phenomena involved and applications of the process are discussed.
Spinal L-Type Calcium Channel Blockade Abolishes Opioid-Induced Sensory Hypersensitivity and Antinociceptive Tolerance (2005)

Recent studies have suggested that prolonged exposure to morphine results in the development of paradoxical, abnormal enhanced pain. It has also been suggested that this enhanced pain state may be interpreted as antinociceptive tolerance. Although the precise mechanisms that drive opioid-induced abnormal pain are not well known, considerable evidence suggests that this state may be supported by enhanced, stimulus-evoked excitatory transmission. We hypothesized that blockade of L-type calcium channels, which are critical for excitatory neurotransmitter release, would alter the development of opioid-induced hyperalgesia and antinociceptive tolerance. Male, Swiss-Webster mice received twice-daily intrathecal injections of morphine (10 microg) alone or in combination with amlodipine (10 microg) for 8 days. Mice receiving repeated morphine injections developed enhanced responses to tactile and thermal stimuli. These hypersensitivities were prevented by the coadministration of the putative selective L-type calcium channel blocker amlodipine. Moreover, mice receiving morphine for 8 days demonstrated a significant rightward shift of the morphine antinociceptive dose-response curve, indicative of antinociceptive tolerance, whereas those that also received amlodipine along with morphine did not demonstrate tolerance. These results suggest that blockade of the L-type calcium channels with amlodipine prevented opioid-induced hyperalgesia and the expression of antinociceptive tolerance to spinal morphine, presumably by reducing stimulus-induced excitatory neurotransmitter release.
Evaluation of Speaker Anonymization on Emotional Speech (2021)

Speech data carries a range of personal information, such as the speaker's identity and emotional state. These attributes can be used for malicious purposes. With the development of virtual assistants, a new generation of privacy threats has emerged. Current studies have addressed the topic of preserving speech privacy. One of them, the VoicePrivacy initiative aims to promote the development of privacy preservation tools for speech technology. The task selected for the VoicePrivacy 2020 Challenge (VPC) is about speaker anonymization. The goal is to hide the source speaker's identity while preserving the linguistic information. The baseline of the VPC makes use of a voice conversion. This paper studies the impact of the speaker anonymization baseline system of the VPC on emotional information present in speech utterances. Evaluation is performed following the VPC rules regarding the attackers' knowledge about the anonymization system. Our results show that the VPC baseline system does not suppress speakers' emotions against informed attackers. When comparing anonymized speech to original speech, the emotion recognition performance is degraded by 15\% relative to IEMOCAP data, similar to the degradation observed for automatic speech recognition used to evaluate the preservation of the linguistic information.
