On-line time-scaling control of a kinematic car with one input (2007)

This paper reports a time-scaling scheme to realize a tracking controller for the non-differentially flat model of the kinematic car with one input which is the steering angle or the angular velocity of the steering angle. The longitudinal velocity of the car is a measurable external signal and cannot be influenced by the controller. Using an on-line time-scaling, driven by the longitudinal velocity of the car, by a scaling output of the tracking controller, and by their time derivatives up to the second order, one can achieve exponential tracking of any sufficiently smooth reference trajectory, similar to the differentially flat case with two control inputs. The price to pay is the modification of the finite traveling time of the reference trajectory according to the time-scaling.
Training Sparse Neural Networks (2017)

The emergence of Deep neural networks has seen human-level performance on large scale computer vision tasks such as image classification. However these deep networks typically contain large amount of parameters due to dense matrix multiplications and convolutions. As a result, these architectures are highly memory intensive, making them less suitable for embedded vision applications. Sparse Computations are known to be much more memory efficient. In this work, we train and build neural networks which implicitly use sparse computations. We introduce additional gate variables to perform parameter selection and show that this is equivalent to using a spike-and-slab prior. We experimentally validate our method on both small and large networks which result in highly sparse neural network models.
Die Reaktionen der tetrameren Blausäure (1956)

Abstract Es werden Umsetzungen der tetrameren Blausäure mit α‐Dicarbonyl‐Verbindungen beschrieben. Mit verschiedenen Acylierungsmitteln durchgeführte Reaktionen liefern Mono‐, Di‐ und Triacyl‐Derivate der tetrameren Blausäure. Mit Oxalylchlorid erfolgt Ringschluß zu einem Pyrazin‐Derivat. Acetimidoester liefert bei milden Bedingungen, unter Reaktion nur einer Aminogruppe der tetrameren Blausäure, den entsprechend substituierten Imidoester. Unter energischeren Bedingungen tritt Ringschluß zum Imidazol‐Derivat ein. Die aus tetramere Blausäure erhaltenen ringförmigen o ‐Dinitrile ergeben mit Alkohol/Salzsäure (Pinner‐Reaktion) eine Imidoestergruppe nur an einer Nitrilgruppe. – Es wird eine theoretische Deutung aller bisher durchgeführten Reaktionen gegeben.
&lt;title&gt;Optical and photochemical properties of C60 films&lt;/title&gt; (1994)

Results of optical studies of thin solid C<SUB>60</SUB> films are presented which highlight some of the unusual optical phenomena observed in fullerene-derived materials. Results of several experiments to determine quantitatively the optical dielectric function are first presented and discussed. We also present results on two different phototransformations of C<SUB>60</SUB> films from a toluene-soluble to a toluene-insoluble state. These processes may have photolithographic application. The first involves the photopolymerization of C<SUB>60</SUB>, and the second is a photo-induced intercalation of di-oxygen into the C<SUB>60</SUB> lattice leading to a film with composition C<SUB>60</SUB>(O<SUB>2</SUB>).
Weather hazard interpretation and forecast by an airborne radar (2009)

A method for modeling and tracking convective clouds within radar images is presented. An object modeling approach is used, based on the extraction of grayscale skeletons from 2-dimensionnal cross-section of 3-dimensional radar data. Grayscale skeletons are appropriate shape descriptors for nonrigid and heterogeneous objects, in which gray-level local maxima correspond to regions of interest. Linking meta-data to some chosen points of the skeleton enhances the modeling scheme; this provides a good representation of the weather scene in terms of hazards for an aircraft. Skeletons are stored within a graph structure and tracked among successive pictures by means of relaxation labeling processes. The deduced advection field is used to nowcast the clouds evolution. Preliminary results are satisfying concerning advection forecast
A REGISTRATION METHOD OF POINT CLOUDS COLLECTED BY MOBILE LIDAR USING SOLELY STANDARD LAS FILES INFORMATION (2017)

Abstract. In the last few years, LiDAR sensors installed in terrestrial vehicles have been revealed as an efficient method to collect very dense 3D georeferenced information. The possibility of creating very dense point clouds representing the surface surrounding the sensor, at a given moment, in a very fast, detailed and easy way, shows the potential of this technology to be used for cartography and digital terrain models production in large scale. However, there are still some limitations associated with the use of this technology. When several acquisitions of the same area with the same device, are made, differences between the clouds can be observed. The range of that differences can go from few centimetres to some several tens of centimetres, mainly in urban and high vegetation areas where the occultation of the GNSS system introduces a degradation of the georeferenced trajectory. Along this article a different method point cloud registration is proposed. In addition to the efficiency and speed of execution, the main advantages of the method are related to the fact that the adjustment is continuously made over the trajectory, based on the GPS time. The process is fully automatic and only information recorded in the standard LAS files is used, without the need for any auxiliary information, in particular regarding the trajectory.
The Win-Win Solution: Guaranteeing Fair Shares to Everybody (1999)

This work is intended as a tool for securing a satisfying, even gratifying, outcome to difficult and complex negotiations. It facilitates the equitable and efficient division of a contested set of goods and the settlement of a dispute without time-consuming haggling or an expensive lawsuit. It removes the risk of one of the parties losing to a more skilled bargainer and allows both rivals to feel that they have won more than half of what was available in a dispute. Beginning wth simple fair-division techniques, the book builds towards a path-breaking procedure that gives equitable, envy-free and efficient solution to a wide range of disputes. This procedure, called adjusted winner, can be applied broadly, from divorce to business to international disputes. Built on a simple point-allocation system, it is as easy to apply as it is to understand, and produces, in a short time, resolutions that have taken expert negotiators weeks and months to work out. The authors present a compelling system that is not only fair but also guarantees that both parties walk away with as much of the win-win potential as possible.
Comparative studies on O-acetylhomoserine sulfhydrylase: physiological role and characterization of the Aspergillus nidulans enzyme. (1993)

O-acetylhomoserine sulfhydrylase (OAH SHLase) from Aspergillus nidulans is an oligomeric protein with a broad substrate specificity with regard to sulfhydryl compounds. As its Saccharomyces cerevisiae counterpart the enzyme also reacts with O-acetylserine and is inhibited by carbonyl reagents but not by antiserum raised against the yeast enzyme. In contrast to Saccharomyces cerevisiae the enzyme is not essential for Aspergillus nidulans as indicated by the completely prototrophic phenotype of OAH SHLase-negative mutants. Its major physiological role in Aspergillus nidulans seems to be recycling of the thiomethyl group of methylthio-adenosine but it is also a constituent of the alternative pathway of cysteine synthesis.
Differential Translation Tunes Uneven Production of Operon-Encoded Proteins (2013)

Clustering of functionally related genes in operons allows for coregulated gene expression in prokaryotes. This is advantageous when equal amounts of gene products are required. Production of protein complexes with an uneven stoichiometry, however, requires tuning mechanisms to generate subunits in appropriate relative quantities. Using comparative genomic analysis, we show that differential translation is a key determinant of modulated expression of genes clustered in operons and that codon bias generally is the best in silico indicator of unequal protein production. Variable ribosome density profiles of polycistronic transcripts correlate strongly with differential translation patterns. In addition, we provide experimental evidence that de novo initiation of translation can occur at intercistronic sites, allowing for differential translation of any gene irrespective of its position on a polycistronic messenger. Thus, modulation of translation efficiency appears to be a universal mode of control in bacteria and archaea that allows for differential production of operon-encoded proteins.
A modular framework for home healthcare monitoring (2012)

Many patients with chronic health problems have multiple ailments but different patients may have different such ailments. Home monitoring systems for individual ailments exist but a patient may have multiple of these, all designed independently. There are no standard architectures so this leads to unmanageable diversity which causes problems for patients in having to learn to use a variety of monitors and for physicians in trying to monitor many patients. The purpose of this project was to design and prototype a next generation modular remote healthcare monitoring system capable of monitoring multiple ailments and extensible to new ailments in order to explore and evaluate the feasibility of such a one-size-fits-all system and assess a practical way to implement it. The project was designed and programmed as if it were to be deployed in a real world situation using real monitors and a smart phone based monitoring scheme and was also implemented and tested in part using a 3D virtual world, Second Life. Using this virtual world platform provided freedom in exploring some of the alternative designs. Implementing such a system using real world devices and not simply designing it conceptually gave a better view of the future of home health monitoring as well as a better framework for developing a future family of remote monitoring systems. The system was evaluated and was determined to provide a reasonable proof of concept patient monitoring architecture that could potentially influence a next generation of modular home healthcare monitoring systems.
Antigen-specific. <i>I</i> region-restricted interactions <i>in vitro</i> between tumor cell lines and T cell hybridomas. (1982)

A series of H-2d B cell tumor lines and one monocytic tumor cell line were shown to be capable of I region-restricted antigen presentation to I-A-d- and I-Ed- restricted, antigen-specific cloned T cell hybridomas. For the most part, antigen presentation correlated with the present of Ia antigens on the presenting cells, although in a few interesting cases Ia-expression lines failed to present antigen. These T cell hybridomas, together with the B cell and to monocyte tumor cell lines, offer a unique set of tools to study the phenomenon of I region-restricted antigen presentation.
Co-operative sensor fusion using time warping in multimodal tomometry for process control (2012)

Recent studies in process tomography have mostly focused on image processing and enhancement of images obtained from Electrical Capacitance, Electrical Resistance, Electrical Impedance, Gamma- and X-ray- tomographic modalities. In the process industries, there is a growing need for fast acting measurement and control procedures, architectures and their implementation within existing sensor and control suites. With this industrial relevance, a multimodal tomometric sensor fusion is studied involving pressure and capacitance measurements in a two phase flow rig. Pressure is measured using standard pressure sensors, whereas the capacitance are measured using arrays of capacitance electrodes placed on the periphery of a section of the pipe in the multiphase flow rig. These capacitance measurements are performed by using ECT-modules. In this paper, the focus is on early slug detection and timely characterization of these slugs formed in the two phase flow. To associate simultaneous occurrence of slug based phenomena in the time series of the pressure and ECT-signals, dynamic time warping (DTW) algorithms are used. The usage of DTW and the multimodal tomometric sensor suite with pressure and ECT-modules leads to a co-operative sensor data fusion, which can help to identify characteristic features of slugs in two phase flows, which can be significant inputs to the process control unit in the assessment/implementation of necessary actions, such as activating choke valves, reducing pump outputs of one or more of the phases flowing in the rig. Time series of pressure and ECT-signal are studied using DTW and results are compared and fused with some discussions on how these could be used in process control.
Tops responsiveness, strategy-proofness and coalition formation problems (2001)

This paper introduces a property over agents' preferences, called Tops Responsiveness Condition. Such a property guarantees that the core in Hedonic Coalition Formation games is not empty. It is also shown that a mechanism exists that selects a stable allocation. It turns out that this mechanism, to be called tops covering, is strategy-proof even if the core is not a singleton. Furthermore, we also find out that the tops covering mechanism is the only strategy-proof mechanism that always selects stable allocations.
Coupled determination of gravimetric and elastic effects on two resonant chemical sensors: love wave and microcantilever platforms (2004)

The field of chemical microsensors for both gas and liquid sensing has been widely investigated in recent years. Several technologies have been utilized which include love-wave acoustic sensors and silicon microcantilevers. Those structures are both used as chemical sensors by adding a sensitive coating to the device surface. Perturbations of the sensitive coating properties induce frequency drift in both devices, thus making chemical detection possible. Microcantilevers are essentially sensitive to the coating mass changes which modify the resonant frequency of the structure. However, the acoustic wave device is sensitive to all types of propagation perturbations which include mass loading and mechanical properties changes of the coating. One of the difficulties in acoustic sensor field is to separate each contribution from the induced frequency shifts. The aim of this paper is to couple experimental results from microcantilevers and love-wave devices in order to identify and separate the two effects. At last, this coupled study is also interesting for gas and liquid phase detection applications, as it will permit to determine the elasticity evolution during the detection process, i.e. the analyte sorption.
A new method for tempering stress measurement in glass panels ; pp. 292–297 (2013)

It is shown that in tempered glass panels the edge stress and the thickness stress are closely related. Therefore the traditional edge stress measurement gives information also about the thickness stress and the surface stress. Thus for complete analysis of stresses near the edge of a glass panel only the edge stress measurement is needed.
Comparing and improving current packet capturing solutions based on commodity hardware (2010)

Capturing network traffic with commodity hardware has become a feasible task: Advances in hardware as well as soft- ware have boosted off-the-shelf hardware to performance levels that some years ago were the domain of expensive special-purpose hardware. However, the capturing hardware still needs to be driven by a well-performing software stack in order to minimise or avoid packet loss. Improving the capturing stack of Linux and FreeBSD has been an extensively covered research topic in the past years. Although the majority of the proposed enhancements have been backed by evaluations, these have mostly been conducted on different hardware platforms and software versions, which renders a comparative assessment of the various approaches difficult, if not impossible.
Seismic evaluation of grouted splice sleeve connections for reinforced precast concrete column–to–cap beam joints in accelerated bridge construction (2015)

| PCI Journal 80 Accelerated bridge construction incorporates innovative techniques and materials to efficiently reduce construction time and traffic disruption. It also improves work-zone safety for workers and commuters. Prefabrication of bridge structural components is a highly effective technique and is one of the accelerated bridge construction methods promoted by the Federal Highway Administration under the category of prefabricated bridge elements and systems. Several bridges have been built or rehabilitated using accelerated bridge construction methods. Examples in Utah include the Interstate 15 (I-15) Core Provo Center Street interchange, the Riverdale Road over Interstate 84 (I-84) bridge, and the I-15 South Layton interchange. Precast concrete deck panels, substructures, and superstructures have been frequently used in accelerated bridge construction. Connections between such reinforced precast concrete elements are among the most critical components of the structure. Researchers are investigating the adequacy of various connection configurations, especially in moderate to high seismic regions. These connections not only have to conform to accelerated bridge construction standards in terms of construction delivery time but must also resist earthquake-induced deformations and stresses. Lateral load capacity, displacement ductility, and reparability are three significant criteria for any connection considered in seismic regions. In this paper, a column–to–cap beam joint is investigated using ■ Although grouted splice sleeve connectors facilitate the construction of precast concrete bridges and accelerate construction, seismic bridge design codes prohibit their use in column plastic hinges.
Queer Theory (2019)

Abstract Since the 1990s, queer theory has been immensely influential in the humanities, and, to a lesser extent, in the social sciences, seeping into discipline after discipline, even disciplines as well insulated as biblical studies. Queer theory is most commonly understood to be the poststructuralist analysis of sex and sexuality, heterosexuality as well as homosexuality. But as queer theory developed, it frequently decoupled from sex and sexuality, its expanded object of analysis becoming normality as such, in its manifold manifestations. This essay begins with a detailed account of the origins of queer theory: its “precursors,” its “exemplars,” and its relations to queer activism. The essay then charts the queer turn in biblical studies, especially New Testament studies, which also began in the 1990s, and traces such work down to the present, commenting both appreciatively and critically on the various paths it has taken. The final section of the essay brings the tale of extrabiblical queer theory fully up to date and reflects on the largely untapped potential for biblical studies of its more recent developments.
Varilux: UV‐cure speeds, elucidates processing of light‐control films (1987)

A new technology for producing light‐control thin films has been developed by physicists at the GM Research Laboratories (GMR). This new class of films — the GMR version of which is known as Varilux — consists of submicron liquid crystal droplets dispersed in a polymer.
Pathophysiologic role of selectins and their ligands in ischemia reperfusion injury (2000)

Research findings are unveiling the potential role of leukocytes and leukocyte adhesion molecules such as selectins in ischemia-reperfusion injury (IRI). "Anti-adhesion" therapy using selectin blocking agents may represent a new approach to treatment of the many diverse clinical disorders in which ischemia-reperfusion occurs, including transplantation, reperfusion after thrombotic events and shock. In this paper we review the pathophysiology of IRI, the different types of selectins and selectin ligands, the clinical implications of selectin blockade in different organs with IRI, and new insights into mechanism of action.
Polycyclic fused phenanthridines: An alternative approach from benzotriazoles (1999)

Abstract We describe an alternative approach to polycyclic phenanthridines (7) and some of their analogues using conditions much milder than those previously reported. The procedure includes the generation of a benzotriazole stabilized carbanion, oxidation of the resulting anion to a radical, and elimination of nitrogen followed by ring closure to produce phenanthridines.
Measuring Activity Level with Actometers: Reliability, Validity, and Arm Length (1983)

EATON, WARREN O. Measuring Activity Level with Actometers: Reliability, Validity, and Arm Length. CHILD DEVELOPMENT, 1983, 54,720-726. The gross motor activity of 27 3and 4-yearolds was measured using teacher ratings, parent responses to the activity scale of the Colorado Childhood Temperament Inventory, and 13 uncalibrated actometers worn singly on the wrist over a period of 1 month in a free play setting. Activity scores from single actometers had low but meaningful levels of reliability; activity scores composited across multiple actometers had high reliability and correlated strongly with parent and teacher measures, even when age and sex effects were partialled. The possibility that limb length is a confounding factor of wrist-placed actometers was also evaluated, and though a nonsignificant trend in this direction was found, validity correlations were essentially unchanged when arm-length effects were removed. The limb-length confound does not appear serious, and when used appropriately actometers provide reliable and valid information on individual differences in children's gross motor activity levels.
