Camera calibration from road lane markings (2003)

Three-dimensional computer vision techniques have been actively studied for the purpose of visual traffic surveillance. To determine the 3-D environment, camera calibration is a crucial step to resolve the relationship between the 3-D world coordinates and their corresponding image coordinates. A novel camera calibration using the geometry properties of road lane markings is proposed. A set of equations that computes the camera parameters from the image coordinates of the road lane markings and lane width is derived. The camera parameters include pan angle, tilt angle, swing angle, focal length, and camera distance. Our results show that the proposed method outperforms the others in terms of accuracy and noise sensitivity. The proposed method accurately determines camera parameters using the appropriate camera model and it is insensitive to perturbation of noise on the calibration pattern.
Low-noise CoCrPtO perpendicular media with improved resolution (2003)

CoCrPtO perpendicular media with coercivities greater than 6000 Oe, M/sub r//M/sub s/ equal to 1.0, and negative nucleation fields exceeding 3000 Oe were produced. The crystallographic, magnetic, and recording properties were optimized with respect to Ru interlayer and CoTaZr soft-underlayer thicknesses. Media with exchange decoupled magnetic grains as small as 7 nm with a narrow size distribution capable of supporting a linear density up to 720 kfci were produced. Thermal decay measured at 50 kfci at ambient temperature was less than 0.1%.
Hierarchical model-order reduction for robust design of parameter-varying systems (2012)

In this paper we introduce a robust method for the model-driven design of reduced parameter-varying analog systems. The ideas behind our approach are twofold: On the one hand we present an algorithm for decreasing the model order of large systems. It utilizes the hierarchical structure of compound systems to simplify component models while ensuring the validity of the composed model. On the other hand we announce a statistical method for reducing circuit equations with parameter variations. Combining both we generate symbolic behavioral models of real-world analog circuits under process variations. Finally, for illustrating we apply the overall procedure to the operational amplifier OpAmp 741 with varying parameters.
Parallel Solution-Phase Synthesis of Acrylonitrile Scaffolds Carrying <scp>l</scp>-α-Amino Acidic or <scp>d</scp>-Glycosyl Residues (2006)

A practical and straightforward protocol for the preparation of a solution-phase library of acrylonitrile scaffolds is reported. Target compounds were obtained in high yield, stereoselectivity, and purity by two simple and practical steps from cyanoacetic acid. Moreover, our study proposes a synthetic approach starting from the constructed library to obtain three-membered heterocycles.
Neuropeptide Y Induced Feeding in the Rat Is Mediated by a Novel Receptor<sup>1</sup> (1997)

There are now six recognized neuropeptide Y (NPY) receptor subtypes (Y1-Y4 and two recently cloned distinct receptors labeled Y5), of which Y1 and one of the Y5's have been suggested could mediate the effect of NPY on feeding. The fragments NPY(2-36) and NPY(3-36), which bind Y1 only poorly, were injected intracerebroventricularly (icv) and found to have similar dose-response relationships to NPY in the stimulation of feeding. However NPY (13-36), which stimulates both Y2 and Y5, caused no increase in food intake, even at high doses. Maximal stimulation with the classical Y1 agonist [Pro34]-NPY produced only 50% of the maximum effect of NPY itself despite fully inhibiting adenylyl cyclase activity in vitro in a Y1 system. The novel fragment [Pro34]-NPY(3-36) is as effective at stimulating food intake as the classical Y1 analogue [Pro34]-NPY but bound to the Y1 receptor with only 1/20th of the affinity of NPY and failed to inhibit adenylyl cyclase through this receptor. [Pro34]-NPY(3-36) is therefore a relatively appetite-selective ligand. Coadministration of high dose NPY(13-36) and [Pro34]NPY did not enhance feeding compared with [Pro34]-NPY alone. In addition, the NPY Y1 receptor antagonist BIBP-3226, which does not bind Y2, Y4, or Y5 receptors, significantly reduced NPY induced feeding. These results indicate that the feeding effect of icv NPY involves a novel receptor and that it is functionally distinct from the recognized receptor subtypes.
Applications of solid-state Raman lasers (2002)

Several laser applications benefit directly from solid-state stimulated Raman scattering (SSRS) technology. These include eye-safe coherent and incoherent lidar, high-resolution 3D marine imaging lidar, laser-corrected adaptive optics, medical lasers, and materials processing. The combination of good beam quality, variable output pulse formats, high conversion efficiency, and frequency agility makes laser sources based on SSRS ideally suited for these applications. In this talk we will discuss specific SSRS laser sources that we have developed for these applications.
Real-time step motor emulator for hardware-in-the-loop simulation (2010)

It is not possible to do automatic testing with step motors in Hardware-in-the-Loop (HIL) simulators because motors may be overheated if working for a long time. Furthermore, possibilities for fault injection are limited and physical interaction is needed to inject faults like a breakdown that can actually be mimicked. We present an emulator in an FPGA that allows to emulate a step motor for automatic testing as well as fault injection for a variety of faults, with the option of emulating more than one step motor in the same FPGA.
A knowledge based manufacturing advisor for CAD (2005)

This thesis presents a knowledge based manufacturing advisor for Computer Aided\nDesign. The aim of the project has been to develop techniques that can help designers to\nevaluate the manufacturability of moulded parts during the design process.\nOne of the major achievements in the research has been the development of a novel\nfeature recognition approach to allow moulding features to be recognised from a CAD\nmodel. Existing feature recognition techniques are not appropriate for moulded parts\nand a new feature recognition approach has been developed that uses a mid-surface\nabstraction from the CAD solid model as the basis for feature recognition. The feature\nrecognition methodology presented in this research is a graph based technique that uses\nan attributed mid-surface adjacency graph as the basis for feature recognition. Feature\nrecognition algorithms have been developed for a range of common moulding features.\nTwo evaluation techniques are presented that measure the quality of the feature\nrecognition results and provide a confidence measure for the manufacturing advice that\nis generated. The first evaluation technique uses the Hausdorff distance to measure the\nsimilarity of the mid-surface model to the CAD solid model that was used to generate it,\nand the second uses a face mapping technique to evaluate the completeness of the\nfeature recognition results.\nA demonstrator for the knowledge based manufacturing advisor has been developed\nwhich incorporates the feature recognition software and an expert system for moulding\nadvice. The expert system provides an interactive software environment in which the\nuser can input details about their part design, and receive tailored manufacturing advice\nfor a range of moulding processes. The demonstrator has been tested on a range of\nrealistic moulded parts.
Stridulation in <i>Acanthophrynus Coronatus</i> (Butler) (Amblypygi, Tarantulidae) (1970)

In April, 965, during a visit to the vicinity o San Blas, Nayarit, Mexico, I collected a living specimen o A canthophrynus coronatus (Butler), the largest known species o the amblypigid amily Tarantulidae. The specimen lived in captivity or over a year, despite several escapes, and ed voraciously on moths and other sol:t-bodied insects. The usual predatory sequence consisted o re- peated light taps on the prey with the whip-like rst legs, the let and right legs acting alternately, t:ollowed by a sudden lunge, too quick or the eye to ollow in detail, with pedipalps spread wide. The prey was caught and impaled on the spines o the pedipalps, and torn to bits by alternating movements o the chelicerae. During
Untersuchungen zur Darstellung von Desoxyzucker‐Steroidglycosiden (1985)

Abstract In stereoselektiven Reaktionen lassen sich die Glycale 1 , 2 und 8 mit Cholesterin sowie Digitoxigenin nach dem N ‐Iodsuccinimid‐Verfahren zu den 2‐Desoxy‐2‐iod‐α‐glycosiden 3 , 4 , 5 und 9 kondensieren. Bei den langsamen Umsetzungen treten die direkten N ‐Iodsuccinimidaddukte wie z.B. 6 als Nebenprodukte auf. In Butanon reagiert 11 nur teilweise zu den erwarteten Glycosiden 12 bzw. 13 , bevorzugt bilden sich die Hex‐2‐enopyranoside 17 bzw. 18 , die auch durch Ferrier‐Umlagerung gewonnen werden können. Ihre Strukturen werden spektroskopisch sowie durch Hydrierung (zu 20 ) bewiesen. Durch hydrierende Iodabspaltung lassen sich die Cardenolidglycoside 10 , 14 und 15 erhalten. Die säurekatalysierte Glycosylierung von Triacetyldigitoxose 21 mit Digitoxigenin führt bei Ausbeuten von maximal 50% zu den α‐ und β‐Anomeren 10 und 25 im Verhältnis ca. 2:3. Höhere Temperaturen steigern den relativen Anteil an β‐Komponente bei stark fallenden Ausbeuten. Die Glycosylierung von Acetobromdigitoxose 22 mit unterschiedlichen Silbersalzen ergibt ebenfalls bei Ausbeuten von ca. 50% Anomerenverhältnis von α:β = 2:3.
Antigenic variants with amino acid deletions clarify a neutralizing epitope specific for influenza B virus Victoria group strains (2001)

To study the neutralizing epitopes of influenza B virus Victoria group strains, two monoclonal antibodies (MAbs) were used to select antigenic variants of the virus. MAbs 10B8 and 8E6 were found to react with B/Victoria group strains in three tests, peroxidase-antiperoxidase staining, haemagglutination inhibition and neutralization tests; no reactivity with B/Yamagata group strains was observed. Analysis of the deduced amino acid sequences of 10B8-induced variants identified a single amino acid deletion at residue 165 or 170, as well as a single amino acid substitution at residues 164 (Asp-->Tyr), 165 (Asn-->Ser or Thr) or 203 (Lys-->Thr or Asn). A single amino acid substitution at residue 241 (Pro-->Ser) was observed in 8E6-induced variants. Three-dimensional analysis showed that the epitopes for both MAbs were situated in close proximity to each other. Since B/Yamagata group strains are characterized by amino acid deletions at residues 164-166, the epitope for MAb 10B8 is strictly specific for B/Victoria group strains.
Governing the Market: Threats to Australia's Stability and Security (2010)

This paper was presented as a lecture in the Senate Occasional Series at Parliament House, Canberra on 8 August and represents an update of 'The Australian Federation 2001: Political structures and economic policy', a 2001 Alfred Deakin Lecture. The basic message here is that unless Australia adopts a middle course between the highly successful corporatist state model of development and the extreme neoliberal model that Australia has selected as its development framework, Australia's internal stability and national security could well be severely degraded over the next two decades. In short, Australia will have to relearn and reapply some strategies and instruments to govern the market. This will involve some restoration of the practices and institutions that were swept away in the name of microeconomic reform over the past two decades. Australia will never be able to match the efficiency of the informal governance structures of corporatist states. For Australia, leadership will have to be provided by its governance institutions in general and parliament in particular.
[Procedure for determination of oxidative modification of plasma fibrinogen]. (2007)

The purpose of the present study was to develop a new procedure for determining the oxidative modification of plasma fibrinogen. The procedure was developed to use blood plasma from 96 males aged 35-60 years who had cardiovascular diseases: 49 patients with coronary heart disease (CHD), including 16 patients with sub-acute myocardial infarction (MI), and 47 patients with arterial hypertension without CHD. The new procedure is as follows: a rapid fibrin isolating method, a reaction with 2,4-dinitrophenylhydrazine in 2 M HCl solution, by subsequently rinsing in the ethanol : ethyl acetate (1:1) solution, dissolving the precipitate in 8 M urea, and by determining the level of the resultant dinitrophenylhydrazones by spectrophotometry at 363 nm, followed by conversion to the plasma concentration of fibrinogen. The procedure is of informative value for the degree of oxidative fibrinogen modification under oxidative stress; it is technically simple, takes little time, and shows a good reproducibility. The values of determined oxidized plasma fibrinogen by the developed procedure show a high positive correlation with the estimates of oxidized total blood protein fraction and with the values of blood lipid peroxidation. The detected elevated level of oxidized fibrinogen in CHD and MI suggests that this index is a new diagnostic marker of oxidative stress in cardiovascular diseases of atherosclerotic genesis.
An in vivo microfabricated scaffold for tendon repair (2005)

A new type of in vivo tissue engineering system for tendon repair in situ after cut or crush of a flexor tendon is described. The system is based on the topographical reaction, alignment, migration and perhaps proliferation of tendon cells on micrometrically grooved substrates made in a biodegradable polymer. Macrophage trapping in the structure may also help to prevent inflammation. Tendon damage including crush and section injury is a fairly frequent occurrence. The conventional treatment is surgical repair, however frequently this leads, especially in hand wounds, to attachment of the tendon surface to the surrounding synovium, which is very undesirable. We present an approach based on using a biodegradable device to ensure that the healing of severed or crushed flexor tendons is aided, synovial adhesion prevented and the final result anatomically correct. The biodegradable sheath carries microgrooves fabricated into the polymer by embossing that orient and guide the cells towards each other from either side of the region of damage. After six weeks an apparently normal functional tendon is reformed.
Identifiability results for blind beamforming in incoherent multipath with small delay spread (2001)

Several explicit identifiability results are derived for deterministic blind beamforming in incoherent multipath with small delay spread. For example, it is shown that if the sum of spatial and fractional sampling diversities exceeds two times the total number of paths, then identifiability can be guaranteed even for one symbol snapshot. The tools come from the theory of low-rank three-way array decomposition (commonly referred to as parallel factor analysis (PARAFAC) and data smoothing in one and two dimensions. New results regarding the Kruskal-rank of certain structured matrices are also included, and they are of interest in their own right.

The developmental regulation of the human ζ-globin gene in transgenic mice employing β-galactosidase as a reporter gene (1992)

We have investigated the developmental and tissue specific expression of the human embryonic zeta-globin gene in transgenic mice. A construct containing 550 bp of zeta-globin 5' flanking region, fused to a beta-galactosidase (lacZ) reporter gene and linked to the locus control region (LCR)-like alpha positive regulatory element (alpha PRE) was employed for the production of transgenic mice. Firstly, we compared the number of live born transgenic mice containing this construct to the number of live born transgenic mice containing the entire zeta-globin gene linked to the alpha PRE or the beta LCR. Data showed that 12% of mice generated from eggs injected with zeta-promoter/lacZ/alpha PRE DNA were transgenic compared to only 2% of mice generated from eggs injected with the entire zeta-globin gene linked to the alpha PRE or the beta LCR. The reduced number of live born transgenic mice containing the latter constructs suggests that death of transgenic embryos, possibly due to thalassaemia, may be occurring. X-gal staining of whole embryos containing the lacZ gene revealed that zeta-globin promoter activity was most pronounced at 8.5-9.5 days of development and was restricted to erythroid cells. By 15 days of development, no zeta-globin promoter activity was detected. These results suggest that the alpha PRE can direct high level expression from the zeta-globin promoter and that sequences required for the correct tissue and developmental specific expression of the human zeta-globin gene are present within 550 bp's of 5' flanking region. Sequences within the body of the zeta-globin gene or 3' of the cap site do not appear to be necessary for correct zeta-globin developmental regulation.
Clarification of animal cell cultures on a large scale by continuous centrifugation (1995)

Animal cells from 80-L and 2000-L fed batch fermentations were removed by a prototype disc stack centrifuge in order to achieve a fast and reliable separation of solids from large quantities of cell culture fluids. The clarification capacity was excellent for animal cells but particles remained in the liquid phase and affected further downstream processing of the cell-free harvest fluid. No significant loss of product was observed. A number of parameters were monitored to optimize process conditions for use with animal cells.
The New Rawls and Constitutional Theory: Does It Really Taste That Much Better? (1994)

It used to be a major enterprise of philosophers to compete for most striking way to describe differentia. Surely most famous and long-lasting such effort was Aristotle's the being rational animal, but there have been other formulae of note put forward too: Plato's the being featherless biped memorable in its own way, as well as definition I associate with Cicero, that being beast with red cheeks, i.e., only being that blushes, or has shame. Let me propose a new entry into human being is ... sweepstakes: the being anniversary celebrating animal. So far as I know, zoologists have discovered no other animal which shares this peculiar propensity with us, as, for example, beaver and bee share our technological proclivities. We are now engaged in celebration of a great anniversary-ten years of Constitutional Commentary-but at same time we might note coincidental fact of another relevant anniversary: just twenty years ago Association of American Law Schools bestowed its highly prestigious Coif Award on a very thick, bright-green book that was only peripherally about law-John Rawls's A Theory of Justice.I These two coincident anniversaries mark events which turned out to be much intertwined. Despite fact that Rawls's book has hardly anything in it that we. would now call constitutional theory, it became, indirectly, a major force in field. In retrospect this appears somewhat remarkable, for book has little by way of usual
A novel SVPWM scheme for Vienna rectifier without current distortion at current zero-crossing point (2014)

Vienna rectifier is one of the most popular topologies for three-phase PFC converter. DC voltage, grid current double loop controller and three-level SVPWM are normally used to control the Vienna rectifier. Accurately detecting the current zero-crossing point is required to achieve the correct SVPWM signals since the output level of Vienna rectifier is also decided by the direction of the phase current. The error of the duty ratio is decided by the error time of the current zero-crossing point detecting and the duty ratio before and after the current zero-crossing point. It can be concluded that the impact of current zero-crossing will be eliminated if the switches near current zero-crossing point are kept “on”. To achieve this goal, a novel SVPWM scheme is proposed by using the certain state combinations of short vectors in each sector. In this method, the calculation of duty ratio will not be affected by the direction of phase current near the zero-crossing point, and therefore the distortion of current caused by current zero-crossing detection error will be eliminated. Simulations and experiments are conducted to verify the presented method.
Research on the Discrete Algorithm of Tooth Surface for a Curve-Face Gear (2019)

Abstract The curve-face gear pair is a new type of face gear pair with a variable transmission ratio. Concerning the complexity of its tooth surface, based on the coordinate transformation principle and the spatial meshing theory, a discrete algorithm of this tooth surface was proposed. The determination rule of the limiting points on the tooth surface was analyzed by introducing the generating method and tooth surface characteristics of this gear tooth. Through the corresponding limiting angles and the distribution law of the contact line, the gear tooth surface was discretized, and the theoretical data points of the tooth surface were obtained. The variations in gear tooth surface in a meshing cycle and under different parameters were analyzed. By comparing the virtual tooth model and the corresponding rolling experiment, the correctness of the tooth surface discrete algorithm of the curve-face gear was verified.
FlexTDMA for delay-stable communications in asynchronous industrial control networks (2010)

To support closed industrial control networks we consider constant end-to-end delay with minimal delay-jitter support in an asynchronous network. The Rate Constrained Static Priority rate-jitter (RCSP-RJ) minimizes jitter while not providing full restoration of traffic at each switch. RCSP-delay-jitter (-DJ) provides jitter free network communication but requires a means of time coordination between switches. We introduce FlexTDMA that allows nearly constant delay bounds with minimal delay-jitter in an asynchronous network. FlexTDMA uses a token bucket to restore the arrival envelope of each flow. This eliminates delay-jitter, simplifies analysis of the network and avoids cyclic dependent issues in network analysis. A network of FlexTDMA switches operate asynchronously and offer nearly constant delay and minimal delay-jitter. FlexTDMA adapts the functional characteristics of RCSP-RJ while providing the performance characteristics of RCSP-DJ, through the use of periodic baselining (transmission at maximal delay bound) of each flow at each switch. When a flow has been baselined the receiving switch establishes a reserved time slot in which the next frame arrival is expected (thus the term flexible TDMA). The value of a baseline event degrades relative to switch clock drift rates. Infrequent baseline collisions cause delay-jitter, and baseline transmission opportunities (TO) can be scheduled thereby minimizing the probability of alignment.
Reveromycin A Inhibits Osteolytic Bone Metastasis of Small-Cell Lung Cancer Cells, SBC-5, through an Antiosteoclastic Activity (2005)

These findings suggest that reveromycin A may inhibit osteolytic bone metastasis through suppression of osteoclast activity by directly inducing apoptosis and indirectly inhibiting tumor cell-derived parathyroid hormone-related peptide production. Therefore, reveromycin A may be a novel, potent therapeutic agent against osteolytic bone metastasis of lung cancer in humans.
