A new way to tackle position/force control for pneumatic robots (2002)

We propose a controller called "joint impedance controller" designed to deal with force and motion trackings. The objective is to control the motion of a biped robot leg during setting and raising phases. As equilibrium of these structures is crucial, transitions between the two phases has to be as soften as possible. Moreover, control laws have not to be too complex and have to take into account pneumatic actuator effects. For these purposes, we purpose a continuous joint impedance controller. The control design is based on a computed torque between the torque actuator and mechanical models. The relation between the torque due to the force applied on the ground and the corresponding position error for each joint is assumed to be of the second order and linear. The asymptotic stability is ensured using Popov criteria. Simulation results of this new controller are presented, leading to a good behaviour of the leg during the two phases at relatively high velocities.
Identification and characterization of human BCL9L gene and mouse Bcl9l gene in silico (2003)

Human BCL9 gene is over-expressed in some cases of acute lymphoblastic leukemia (ALL) with t(1;14)(q21;q32). Drosophila segment polarity gene legless (lgs), encoding wingless-armadillo (WNT - beta-catenin) signaling molecule, is the homolog of human BCL9. Here, we identified and characterized human BCL9-like (BCL9L) gene as well as mouse Bcl9-like (Bcl9l) gene by using bioinformatics. Uncharacterized DLNB11 cDNA (AB094091.1) was derived from human BCL9L gene. Nucleotide sequence of mouse Bcl9l cDNA was determined in silico by assembling mouse ESTs BF464707, BQ258167, 5'-truncated BC003321 cDNA, and mouse genome clone RP24-308H8 (AC125129.5). Human BCL9L and mouse Bcl9l genes were found to consist of eight exons. Exon-intron structure was well conserved between human BCL9L and mouse Bcl9l genes. Human BCL9L (1499 aa) showed 94.0% and 34.8% total-amino-acid identity with mouse Bcl9l (1494 aa) and human BCL9, respectively. Six domains (B9H1-B9H6) were conserved among mammalian BCL9 family proteins. B9H1 and B9H2 domains, and N-terminal part of B9H3 domain were identical to HD1, HD2, and HD3 domains conserved between human BCL9 and Drosophila lgs. B9H4, B9H5 and B9H6 were novel domains. B9H4 domain was characterized by multiple Ser-Pro repeats. Human BCL9L mRNA was expressed in fetal brain, adult lung, amygdala, eye, prostate, and also in several types of tumors including pancreatic cancer, prostate cancer, head and neck tumor and embryonal tumor. BCL9L gene was located between BLR1 and UPK2 genes within the commonly deleted region of neuroblastoma at human chromosome 11q23.3. This is the first report on human BCL9L and mouse Bcl9l.
Low-complexity channel estimation for wireless ofdm systems (2004)

Wireless communication systems incorporating coherent OFDM requires the estimation and tracking of the time-varying channel response for accurate demodulation of data at the receiver. In pilot-symbol-assisted (PSA) OFDM systems, the minimum mean-square-error (MMSE) estimator is a good channel estimation technique given that channel statistics are known. However, the major drawback of the MMSE estimator is its high computational complexity, which grows with number of pilots. Piecewise-linear interpolation is a low complexity solution to the channel estimation task. In this paper we derive exact expressions for the channel estimation error as a function of pilot spacing, channel statistics and channel noise, when piecewise-linear interpolation is incorporated. We compare the performance of piecewise-linear interpolation against that of a low complexity MMSE technique (piecewise-MMSE interpolation) under both matched and mismatched conditions of channel statistics. Results show that a piecewise-linear interpolator performs better than a mismatched piecewise-MSSE interpolator of same complexity.
<title>Phenomenological BRDF modeling for engineering applications</title> (1997)

The application of analytical light scattering techniques for virtual prototyping the optical performance of paint coatings provides an effective tool for optimizing paint design for specific optical requirements. This paper describes the phenomenological basis for the scattering coatings computer aided design (ScatCad) code. The ScatCad code predicts the bidirectional reflectance distribution function (BRDF) and the hemispherical directional reflectance (HDR) of pigmented paint coatings for the purpose of coating design optimization. The code uses techniques for computing the pigment single scattering phase function, multiple scattering radiative transfer, and rough surface scattering to calculate the BRDF and HDR based on the fundamental optical properties of the pigment(s) and binder, pigment number density and size distribution, and surface roughness of the binder-interface and substrate. This is a significant enhancement to the two- flux, Kubelka-Munk analysis that has traditionally been used in the coatings industry. Example calculations and comparison with measurements are also presented.
Allocation of Risk Capital in Financial Institutions (1999)

Francesco Saita is a Researcher at Universitii Bocconi. The attention devoted to risk management in recent years has mostly focused on risk measurement, whereas the use of such measures in actual decision processes has been unaddressed. This paper focuses on the implementation issues involved with using value-at-risk measures in the capital-allocation process. In particular, this paper deals with the process of capital allocation and its consequences on risk-adjusted performance evaluation. When defining a measure of risk-adjusted performance, there is no multipurpose solution: the measure must be chosen based on the characteristics of each business unit and the degree of centralization or decentralization of the allocation process. Greater attention to capital allocation is therefore required so that more sophisticated risk measures can produce the desired results.
<title>The Use Of Electro-Mechanical Mirror Scanning Devices</title> (1977)

Optical scanners in current use can be divided neatly into two basic families: devices with no moving mirror such as cathode ray tubes and electro- and acousto-optics, and electro-mechanical devices. This paper is limited to the latter group. Discussed are the five generic types, the attributes and limitations of each, ancillary equipment such as drives and control circuits and, in a general way, the suitability of each for various applications. X-Y scanning is covered. Because of the current interest in bar code scanning both laser and white light bar code systems are presented in some detail to illustrate the optical and electronic elements of systems incorporating electro-mechanical scan-ners. Throughout this paper, references to scan angle mean the angular motion of the mirror, not that of the reflected beam. Beam motion is double the mirror scan angle.

The impact of maternal malaria on newborns (2010)

Malaria is common during pregnancy and can have serious consequences for neonatal health. Neonatal morbidity and mortality can be significantly reduced by proper implementation of insecticide-treated nets and intermittent preventive treatment.
Adaptive Waveform Inversion – FWI Without Cycle Skipping (2015)

Summary We present a newly proposed method for performing full-waveform inversion that appears to be immune to the effects of cycle skipping – Adaptive Waveform Inversion (AWI). The method uses Wiener filters to match observed and predicted data. The inversion is formulated so that the model is updated in the direction that drives these Wiener filters towards delta functions at zero lag, at which point the true model has been recovered. The method is computationally efficient, it appears to be universally applicable, and it recovers the correct model when conventional FWI fails entirely.
Role and Technology of the Power Split Apparatus in Hybrid Electric Vehicles (2007)

Hybrid electric vehicles (HEVs) are an in-between step for the transition from the conventional high-consumption, high- pollution vehicles to the future efficient and clean vehicles. In this paper the main HEV architectures are at first reviewed, focusing on the series-parallel one and the key role played by the power split apparatus within this architecture. Then the two solutions used for implementing the power split, namely the mechanical solution, which is built up around a planetary gear, and the electric one, which is constituted by an electric machine with both rotating members, are read up. At last, a performance comparison of the two solutions is given.
Efficient Coding of Depth Map by Exploiting Temporal Correlation (2014)

With the growing demands for 3D and multi-view video content, efficient depth data coding becomes a vital issue in image and video coding area. In this paper, we propose a simple depth coding scheme using multiple prediction modes exploiting temporal correlation of depth map. Current depth coding techniques mostly depend on intra-coding mode that cannot get the advantage of temporal redundancy in the depth maps and higher spatial redundancy in inter-predicted depth residuals. Depth maps are characterized by smooth regions with sharp edges that play an important role in the view synthesis process. As depth maps are more sensitive to coding errors, use of transformation or approximation of edges by explicit edge modelling has impact on view synthesis quality. Moreover, lossy compression of depth map brings additional geometrical distortion to synthetic view. In this paper, we have demonstrated that encoding inter-coded depth block residuals with quantization at pixel domain is more efficient than the intra-coding techniques relying on explicit edge preservation. On standard 3D video sequences, the proposed depth coding has achieved superior image quality of synthesized views against the new 3D-HEVC standard for depth map bit-rate 0.25 bpp or higher.

Triple-Hélices : études spectroscopiques (1991)

La sequence d'un adn bicatenaire peut etre reconnue par un oligodesoxynucleotide simple brin qui se fixe dans le grand sillon de la double helice, formant localement une triple helice. La formation d'une triple helice reste limitee a des sequences homopuriques-homopyrimidiques, ou toutes les purines (a ou g) se trouvent sur le meme brin. La specificite de ce ligand pour sa cible, qui repose sur la formation de liaisons hydrogene de type hoogsteen, a ete mesuree par spectroscopie d'absorption. L'introduction d'une mutation ponctuelle sur la cible induit une perte d'affinite importante du ligand, confirmant sa specificite de fixation. Un phenomene de luminescence aisement observable, le transfert d'energie d'excitation, a permis de distinguer une cible complementaire d'une cible mutee. L'affinite d'un oligodesoxynucleotide pour une sequence mixte, comprenant une ou deux pyrimidine(s) dans le brin riche en purines a ete egalement etudiee. Contrairement au cas de l'adn double-brin, peu de ligands de la triple helice sont connus. Le bromure d'ethidium s'intercale dans une triple helice, avec une affinite moindre que pour une double helice. Le site a la jonction entre la double et la triple-helice s'est revele tres favorable a l'intercalation de differents composes. Une recherche systematique sur differents composes aromatiques plans a permis de mettre en evidence des ligands specifiques de la triple helice capable de s'intercaler entre deux triplets de bases t. A. T. La triple helice est stabilisee en presence de ces composes, qui induisent des dommages sur la cible a des sites specifiques en presence de lumiere
Non-Double-Couple Earthquakes in the Long Valley Volcanic Region (2006)

To better understand the connection between earthquake production and geothermal/magmatic systems, we studied the extent of fluid-influenced faulting in the Long Valley volcanic region. We focused on a 100-km-wide circular area centered at the Long Valley caldera that also encompassed the Mono-Inyo craters to the north and the Sierra Nevada mountain block to the south. We performed a comprehensive search for events greater than M 3.5 since 1993 with significant coseismic volume changes in their source region. Using three-component broadband digital waveforms at regional distances, we solved for four different source models: double couple (dc), deviatoric dc + isotropic, and full moment tensor. Using the F -test as a statistical aid, we determined which of the four models was most appropriate for each event. We then conducted stability tests to determine the robustness of the focal mechanism solutions and isotropic components. Our results show that fluid-influenced earthquakes in the magnitude range studied are quite rare in the Long Valley volcanic region. Of 33 high-quality events, 28 are best characterized by a simple dc source model, 4 by a dc + isotropic source model, and 1 by a full moment tensor model.
Conceptual analysis of Internet of Things use cases in Banking domain (2019)

Internet of Things (IoT) is an element of smart infrastructure and banking is one of the potential domains which can leverage a huge opportunity from IoT technology. Currently Automated Teller Machine (ATM), Point of service (POS) terminal, mobile banking acts as the edge for banking infrastructure. These digital edge systems in banking bring in one on one interactions with customers and their requirements which opens up opportunities for data acquisition, processing, analytics and decision making on that data. In this paper, banking, financial services and insurance (BFSI) based IoT application usage / use cases with concepts, current trends, opportunities and challenges will be discussed. Smart banking edge systems are needed to address the growing demands on BFSI requirements and IoT is one of the elements for Digital banking infrastructure that will meet the expectations.
Generating mixed hardware/software systems from SDL specifications (2002)

A new approach for the translation of SDL specifications to a mixed hardware/software system is presented. Based on the computational model of communicating extended finite state machines (EFSM) the control flow is separated from data flow of the SDL process. Hence for the first time it is possible to generate a mixed hardware/software implementation of an SDL process. This technique also reduces the complexity for high-level and register-transfer synthesis tools for the hardware parts of the system. The advantage of this methodology is shown by a design example of a wireless communication chip.
Real-time clothing recognition in surveillance videos (2011)

Recognition of clothing categories from videos is appealing to emerging applications such as intelligent customer profile analysis and computer-aided fashion design. This paper presents a complete system to tag clothing categories in real-time, which addresses some practical complications in surveillance videos. Specifically, we take advantage of face detection and tracking to locate human figures and develop an efficient clothing segmentation method utilizing Voronoi images to select seeds for region growing. We compare clothing representations combining color histograms and 3 different texture descriptors. Evaluated on a video dataset with 937 persons and 25441 cloth instances, the system demonstrates promising results in recognizing 8 clothing categories.
A coupling alternative to reactive transport simulations for long-term prediction of chemical reactions in heterogeneous CO <sub>2</sub> storage systems (2015)

Abstract. Fully coupled, multi-phase reactive transport simulations of CO2 storage systems can be approximated by a simplified one-way coupling of hydrodynamics and reactive chemistry. The main characteristics of such systems, and hypotheses underlying the proposed alternative coupling, are (i) that the presence of CO2 is the only driving force for chemical reactions and (ii) that its migration in the reservoir is only marginally affected by immobilisation due to chemical reactions. In the simplified coupling, the exposure time to CO2 of each element of the hydrodynamic grid is estimated by non-reactive simulations and the reaction path of one single batch geochemical model is applied to each grid element during its exposure time. In heterogeneous settings, analytical scaling relationships provide the dependency of velocity and amount of reactions to porosity and gas saturation. The analysis of TOUGHREACT fully coupled reactive transport simulations of CO2 injection in saline aquifer, inspired to the Ketzin pilot site (Germany), both in homogeneous and heterogeneous settings, confirms that the reaction paths predicted by fully coupled simulations in every element of the grid show a high degree of self-similarity. A threshold value for the minimum concentration of dissolved CO2 considered chemically active is shown to mitigate the effects of the discrepancy between dissolved CO2 migration in non-reactive and fully coupled simulations. In real life, the optimal threshold value is unknown and has to be estimated, e.g. by means of 1-D or 2-D simulations, resulting in an uncertainty ultimately due to the process de-coupling. However, such uncertainty is more than acceptable given that the alternative coupling enables using grids of the order of millions of elements, profiting from much better description of heterogeneous reservoirs at a fraction of the calculation time of fully coupled models.
MIMO processing for HSDPA in UTRA TDD (2005)

Multiple input multiple output (MIMO) processing is expected to provide significant enhancements to the capacity of UMTS systems by improving the spectral efficiency. A number of candidate MIMO techniques have been proposed and are currently being studied by 3GPP. While MIMO techniques for UTRA FDD have been thoroughly studied, little effort has been spent on investigating MIMO for UTRA TDD. We analyse the suitability of various MIMO techniques for UTRA TDD and present initial simulation results.
Use of recombinant human erythropoietin in the treatment of anemia in patients who have cancer. (1992)

Mild to moderate anemia associated with malignant disease can contribute to the overall morbidity in patients with cancer. Because this anemia has been linked to a blunted erythropoietin response, recombinant human erythropoietin (r-HuEPO) was assessed as a means to correct it and provide some degree of palliation. Three different patient populations were studied: one population not administered chemotherapy, a second population administered chemotherapy that did not include cisplatin, and a third population administered chemotherapy that included cisplatin. In all patient populations, r-HuEPO increased hematocrit values compare with placebo. In the two chemotherapy-treated populations, r-HuEPO decreased blood transfusion requirements after the first month of therapy. Patient-rated energy levels, ability to engage in daily activity, and overall quality of life improved in patients who responded to r-HuEPO therapy with an increase in hematocrit values of 6 percentage points or more. Thus, it appears that r-HuEPO may be a useful adjunct for palliation and treatment of anemia in patients with cancer.
An Outbreak of Severe <i>Clostridium difficile</i>–Associated Disease Possibly Related to Inappropriate Antimicrobial Therapy for Community-Acquired Pneumonia (2007)

We report a severe outbreak of Clostridium difficile infection. According to a chart review, half of the patients who received treatment for bacterial pneumonia before they developed C. difficile infection may not have had pneumonia. Excessive use of the hospital's new pneumonia care plan during the influenza season may have contributed to the intensity of this outbreak.
On the nature of the so-called subsurface longitudinal wave and/or the surface longitudinal “creeping” wave (1990)

Abstract The elastic wave field of certain angle beam probes used for nondestructive testing of solid materials, like steel, has been shown to exhibit a so-called subsurface longitudinal wave, i.e., a wavefront traveling with the pressure wave speed having a beam angle of approximate 74° in steel. In addition, this wavefront is supposed to be connected to the stress-free surface via a headwave, which radiates a nearly plane wave with shear velocity into the bulk material under an angle of 33°, approximately, and giving rise to a strongly attenuated longitudinal “creeping” wave on the surface. In the present paper we utilize a new numerical scheme for the computation of elastodynamic wave fields in nearly arbitrary environments, called elastodynamic finite integration technique (EFIT), to predict the above-mentioned wave features quantitatively. Furthermore, we employ several analytical and analytical-numerical integration procedures to evaluate the angle beam probe plane wave spectrum in terms of an inverse spatial Fourier transform. This gives rise to a theoretical interpretation of the physical origin of the numerically computed EFIT wavefronts. Essential results are as follows: the particular wavefronts of angle beam probes, as referred to in this paper, are exclusively associated with a finite aperture radiating into an elastic half-space; they cannot be explained in terms of single homogeneous and inhomogeneous plane waves. The subsurface longitudinal wave emerges from the superposition of the edge pressure waves of the transducer, resulting in a propagation with pressure wave speed, but, in the nearfield, where it is often employed, it is not longitudinally polarized. On the surface, and very close to it, the superposition of the subsurface longitudinal wave and the head waves associated with the probe edges gives rise to a strongly attenuated wavefront exhibiting longitudinal as well as transverse particle displacement components, but neither a surface wave nor a creeping wave is really involved. The bulk shear wavefront is not an appendix of the head wave but the “geometric optical” shear wave radiation pattern of the finite probe.
Finger vein identification system using two cameras (2014)

Taking advantage of the three‐dimensional (3D) structure of finger veins located inside a finger, a novel finger vein identification system (FVIS) using two cameras with different fusion techniques is proposed. Compared with the traditional single‐camera‐based FVIS, the proposed system can generate more discriminative information by fusing information from two simultaneous captured images and can enhance the matching accuracy. Experimental results obtained using the authors' established database containing 436 fingers from 109 subjects verify the feasibility of the proposed system.
The snare method of laparoscopic sterilization: an analysis of 1,000 cases with 4 failures. (1977)

The snare method has proven to be an effective method of tubal resection for sterilization. In the most experienced hands, significant complications are indeed rare. However, the failure rate appears to be higher than that of the coagulation-alone method, at least in the postabortal patient. The necessity for pathologic confirmation, a tradition of surgery, is critically questioned. Additional coagulation of the tubal ends after resection is now recommended, especially in the patient seeking abortion as well as sterilization. The authors await the comparative long-term results of bipolar forceps and the newer mechanical methods of laparoscopic tubal sterilization. It is conceivable that the snare and other unipolar electrosurgical instruments designed for female sterilization will become obsolete.
