Effective fault detection &#x00026; isolation using bond graph-based Domain decomposition (2009)

The problem of fault detection and isolation in complex chemical/biochemical plants can be effectively addressed by a hierarchical strategy involving successive narrowing of the search space of potential faults. A bond graph network is one means of achieving a decomposition based on a separation of the physical domains such as mechanical, electrical, etc. In this work, bond graph theory is used with a three-stage procedure to fulfill the tasks of fault detection and isolation. First, the multivariate statistical method of principal component analysis is used to remove outliers and reduce the data dimensions. Second, the discrete wavelet transform is applied to the resulting scores to abstract the dynamics at different scales. In the third and final step, the Mahalanobis distance is applied to the results found in step two to calculate the confidence level. Based on the degree of violation from the nominal probability level, the detection of a potential fault is concluded to be true. Following a conclusion of true, fault isolation is achieved by comparing the time scale at which the violation of the nominal probability level occurred to the time scale associated with each physical domain. Two examples are presented to demonstrate these concepts.

Multiplexing Approaches for a 12 x 4 Array of Silicon Photomultipliers (2014)

Two resistor network multiplexing circuits for a 12 × 4 array of SiPMs were constructed and tested. Both circuits encode the position and energy information from 48 SiPM pixels in only 4 analog channels. The two circuits differ in that one buffers each SiPM output with a non-inverting voltage-feedback operational amplifier before multiplexing, whereas the second one connects the output of the SiPMs directly to a charge division resistor network. The energy and timing resolution were measured with a 4 × 4 array of LYSO scintillator crystals with size matched to the SiPM pixel size. The measurement was done in 3 steps to cover all 12 × 4 SiPMs. Both circuits gave an energy resolution of 14%. The single sided timing resolution for the buffered output circuit was 2.86 ns, using a 350-650 keV energy window. In comparison, the timing for the circuit with direct connections between SiPMs and the resistor network was 3.54 ns, using the same energy window. Based on these results, the predicted coincidence timing resolutions are 4.0 ns and 5.0 ns, respectively. The coupling of the SiPM capacitance with the resistor network results in different signal shaping time constants for different SiPMs in the passive resistor network, causing a delay in trigger time for the inner SiPM signals. On the other hand, the circuit with buffer amplifiers does not suffer from this effect, and the pulse shape is more uniform across the SiPMs. We also demonstrate, using a 10 × 10 array of 1.5 mm LYSO crystals, that the inclusion of multiple SiPMs in both circuits reduces the detector's ability to resolve crystals in the flood histograms. The amount of noise increases with number of SiPMs in the multiplexing circuit.

AUTOMATING PRODUCT CLASSIFICATION: THE IMPACT OF STANDARDIZATION (2004)

Approaches to automating product classification adopt mainly algorithms and tools for classification in general, such as Vector Space Model, Bayesian Classification and K-Nearest Neighbor Classification, or take classification systems as (database) schemas that have to be integrated. Much work has been carried out on applying, evaluating and improving these tools for this specific domain, product data in B2B e-commerce. The formal specification of a product classification system (PCS) is seen as input data; hence this data has to be imported and often converted into an internal representation. This paper takes a closer look at this input data and examines its structure, semantic richness and degree of standardization. The reason is that standards for product classification systems and standardized specifications address the data exchange issues of these systems -- and more important, are able to increase the success of automated product classification. To do so the paper will derive and analyze major standardization trends, show their interdependencies and evaluate their impact on automated classification.
Marketing Information Systems in Universities (1993)

Explains how it is possible for universities which are part of the UCCA/PCAS system to develop insights into their recruitment process. The changes to the university sector and government funding of higher education make it critical for universities to understand the higher education marketplace. Shows how extracts from the main UCCA database can be used to model the selection process, competitor analysis and geodemographic modelling. The effective use of information already held by universities will allow them to respond to a changing marketplace in a planned and co‐ordinated manner.
Oligodendrocytes: from development to demyelinated lesion repair. (1999)

Spontaneous but incomplete remyelination is observed after a demyelinating lesion. We know since ten years now that oligodendrocyte progenitors, (OP) and totipotent neural stem cells remain present in the central nervous system of adult mammals. Moreover, these OP are more likely the cellular source of remyelinating cells. Here, we intend to demonstrate that the understanding of the myelination process that occurs during development might lead to new treatments aimed at inducing remyelination: stimulation of resident OP or grafting of purified perinatal OP.

Scan Line Intensity-Elevation Ratio (SLIER): An Airborne LiDAR Ratio Index for Automatic Water Surface Mapping (2019)

Owing to the characteristics of how a laser interacts with the water surface and water column, the measured Light Detection and Ranging (LiDAR) intensity values are different with respect to the laser wavelength, the scanning geometry and the reflection mechanism. Depending on the instantaneous water condition and the laser incidence angle, laser dropouts can appear, causing null returns or empty holes found in the collected LiDAR data. This variable intensity response offers a valuable opportunity for using airborne LiDAR sensors for automatic identification of water regions, and thus, we previously proposed an airborne LiDAR-based ratio index named the scan line intensity-elevation ratio (SLIER). Over the water surface, airborne LiDAR data are always found to have a high fluctuation of the intensity value and low variation of the elevation along each scan line, and thus, the water region has a higher SLIER value compared to the land. We examined the SLIER on a multispectral airborne LiDAR dataset collected by Optech Titan and a monochromatic airborne LiDAR dataset collected by Optech Galaxy on a natural rocky shore and a man-made shore. Our experiments showed that SLIER was able to provide a high separability between land and water regions and was able to outperform the traditional normalized difference water index (NDWI) for estimation of the water surface. With the use of SLIER as a mechanism for training data selection, our case studies demonstrated an overall accuracy of 98% in the use of either monochromatic or multispectral LiDAR data, regardless of the laser channel being used.

Obstacles and foliage discrimination using lidar (2016)

A central challenge to autonomous off-road navigation is discriminating between obstacles that are safe to drive over and those that pose a hazard to navigation and so must be circumnavigated. Foliage, which can often be safely driven over, presents two important perception problems. First, foliage can appear as a large impenetrable obstacle, and so must be discriminated from other objects. Second, real obstacles are much harder to detect when adjacent to or occluded by foliage and many detection methods fail to detect them due to additional clutter and partial occlusions from foliage. This paper addresses both the discrimination of foliage, and the detection of obstacles in and near foliage using Lidar. Our approach uses neighboring pixels in a depth image to construct features at each pixel that provide local surface properites. A generative model for obstacles is used to accumulate probabilistic evidence for obstacles and foliage in the vicinity of a moving platform. Detection of obstacles is then based on evidence within overlapping cells of a map without the need to segment segment obstacles and foliage. High accuracy obstacle and foliage discrimination is obtained and compared with the use of a point scatter measure.
Hepatic overexpression of sterol carrier protein-2 inhibits VLDL production and reciprocally enhances biliary lipid secretion (2003)

We examined in vivo a role for sterol carrier protein-2 (SCP-2) in the regulation of lipid secretion across the hepatic sinusoidal and canalicular membranes. Recombinant adenovirus Ad.rSCP2 was used to overexpress SCP-2 in livers of mice. We determined plasma, hepatic, and biliary lipid concentrations; hepatic fatty acid (FA) and cholesterol synthesis; hepatic and biliary phosphatidylcholine (PC) molecular species; and VLDL triglyceride production. In Ad.rSCP2 mice, there was marked inhibition of hepatic fatty acids and cholesterol synthesis to <62% of control mice. Hepatic triglyceride contents were decreased, while cholesterol and phospholipids concentrations were elevated in Ad.rSCP2 mice. Hepatic VLDL triglyceride production fell in Ad.rSCP2 mice to 39% of control values. As expected, biliary cholesterol, phospholipids, bile acids outputs, and biliary PC hydrophobic index were significantly increased in Ad.rSCP2 mice. These studies indicate that SCP-2 overexpression in the liver markedly inhibits lipid synthesis as well as VLDL production, and alters hepatic lipid contents. In contrast, SCP-2 increased biliary lipid secretion and the proportion of hydrophobic PC molecular species in bile. These effects suggest a key regulatory role for SCP-2 in hepatic lipid metabolism and the existence of a reciprocal relationship between the fluxes of lipids across the sinusoidal and canalicular membranes.
Metal-insulator transitions (1998)

Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of orders of magnitude, and are widely observed in condensed-matter systems. This article presents the observations and current understanding of the metal-insulator transition with a pedagogical introduction to the subject. Especially important are the transitions driven by correlation effects associated with the electron-electron interaction. The insulating phase caused by the correlation effects is categorized as the Mott Insulator. Near the transition point the metallic state shows fluctuations and orderings in the spin, charge, and orbital degrees of freedom. The properties of these metals are frequently quite different from those of ordinary metals, as measured by transport, optical, and magnetic probes. The review first describes theoretical approaches to the unusual metallic states and to the metal-insulator transition. The Fermi-liquid theory treats the correlations that can be adiabatically connected with the noninteracting picture. Strong-coupling models that do not require Fermi-liquid behavior have also been developed. Much work has also been done on the scaling theory of the transition. A central issue for this review is the evaluation of these approaches in simple theoretical systems such as the Hubbard model and $t\ensuremath{-}J$ models. Another key issue is strong competition among various orderings as in the interplay of spin and orbital fluctuations. Experimentally, the unusual properties of the metallic state near the insulating transition have been most extensively studied in $d$-electron systems. In particular, there is revived interest in transition-metal oxides, motivated by the epoch-making findings of high-temperature superconductivity in cuprates and colossal magnetoresistance in manganites. The article reviews the rich phenomena of anomalous metallicity, taking as examples Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Ru compounds. The diverse phenomena include strong spin and orbital fluctuations, mass renormalization effects, incoherence of charge dynamics, and phase transitions under control of key parameters such as band filling, bandwidth, and dimensionality. These parameters are experimentally varied by doping, pressure, chemical composition, and magnetic fields. Much of the observed behavior can be described by the current theory. Open questions and future problems are also extracted from comparison between experimental results and theoretical achievements.

NbTiN Based Tuning Structures for Broadband Nb-Al 2 O >3 -Nb SIS Mixers from 640 GHz-800 GHz (2001)

We present measurements with a prototype waveguide SIS mixer for band 2 (640 GHz – 800 GHz) of HIFI (Heterodyne Instrument for FIRST). The Nb/Al2O3/Nb junctions have an RnA product from 12–18 Ωμm. These junctions are embedded in microstrip circuits tuning out the device capacitance using a NbTiN ground layer and various top conductor materials such as NbTiN, Nb and Al. The NbTiN films are fabricated by DC magnetron sputtering which is optimized for a minimum value of the DC resistivity and for a high critical temperature by varying the sputter pressure, sputter power and Ar:N2 flow. Typical NbTiN film parameters for device fabrication are ρ = 120 μΩcm and Tc = 14.5 K. The best uncorrected noise temperatures we measured so far are for devices with NbTiN/SiO2/Nb tuning. At 4.2 K bath temperature, a standard Yfactor measurement yields uncorrected receiver noise temperatures of 350 K at 642 GHz and 500 K at 810 GHz for 1.5 GHz intermediate frequency. We discuss the effect of the various tuning circuit materials on the mixer performance. In addition, measurements at IF’s between 4 GHz and 8 GHz will be presented.
A Pipeline for Trunk Detection in Trellis Structured Apple Orchards (2015)

The ability of robots to meticulously cover large areas while gathering sensor data has widespread applications in precision agriculture. For autonomous operations in orchards, a suitable information management system is required, within which we can gather and process data relating to the state and performance of the crop over time, such as distinct yield count, canopy volume, and crop health. An efficient way to structure an information system is to discretize it to the individual tree, for which tree segmentation/detection is a key component. This paper presents a tree trunk detection pipeline for identifying individual trees in a trellis structured apple orchard, using ground‐based lidar and image data. A coarse observation of trunk candidates is initially made using a Hough transformation on point cloud lidar data. These candidates are projected into the camera images, where pixelwise classification is used to update their likelihood of being a tree trunk. Detection is achieved by using a hidden semi‐Markov model to leverage from contextual information provided by the repetitive structure of an orchard. By repeating this over individual orchard rows, we are able to build a tree map over the farm, which can be either GPS localized or represented topologically by the row and tree number. The pipeline was evaluated at a commercial apple orchard near Melbourne, Australia. Data were collected at different times of year, covering an area of 1.6 ha containing different apple varieties planted on two types of trellis systems: a vertical I‐trellis structure and a Güttingen V‐trellis structure. The results show good trunk detection performance for both apple varieties and trellis structures during the preharvest season (87– accuracy) and near perfect trunk detection performance (99% accuracy) during the flowering season.
Volume production of unique plastic surface-mount modules for the IBM 80-ns 1-Mbit DRAM chip by area wire bond techniques (2003)

The implementation of a 26-lead small-outline J-lead (SOJ) integrated-circuit surface-solder plastic package is described. A plastic SOJ package for this chip design which, by conventional wire bond methods, is neither feasible nor manufacturable is used. The packaging method, developed in parallel with device design, takes advantage of unconventional chip input/output (I/O) pad placement to produce an internal package construction called area-wire-bond (A-wire) which complements mechanical, thermal, and electrical device performance functions. Data gathered during the qualification of the manufacturing lines have shown that A-wire packages consistently exceed established IBM reliability criteria for semiconductor packages.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A prototype of the MRI-compatible ultra-high resolution SPECT for in vivo mice brain imaging (2009)

In this paper, we will present a preliminary study based on a prototype of the MRI-compatible, ultra-high resolution SPECT system for use in a pre-existing Siemens 3.0 T MR scanner. The system uses an ultra-high special resolution energy-resolved photon-counting (ERPC) CdTe detector that we have recently developed. This detector consists of eight detector hybrids, each having a pixilated CdTe detector of 1 mm thickness, bump-bonded to a custom-designed CMOS readout ASIC. Each detector hybrid offers an imaging area of 1.1 cm × 2.2 cm that is divided into an array of 32 × 64 pixels with a pitch size of 350 ¿m × 350 ¿m. A prototype SPECT system has been designed and tailored for use inside the 3.0 T Siemens scanner for tomographic imaging. It consists of a single ERPC detector head, coupled to a collimation aperture. The system is supported by a non-magnetic gantry that allows the system to be moved in and out the Siemens scanner and to be rotated around the object to obtain a sufficient angular sampling. All shielding, supporting and cooling structures are proved to be MRI-compatible. The imaging performance of the prototype system with presence of magnetic field will be evaluated by using image of the Co57 point source and the results will be presented.
