User Privacy Issues in Eucalyptus: A Private Cloud Computing Environment (2011)

The highly scalable nature of Cloud Computing enables its users to utilize distributed computational resources and access large amounts of data using different interfaces. Cloud entities including cloud users, service providers and business partners share the available resources at different levels of technological operations. However, the Cloud Computing framework is inherently susceptible to a great number of security threats due to the amalgamation of different computing technologies that make it a complex architecture. Among all the potential threats, those targeting the users' data are significantly important and must be thwarted in precedence to facilitate effective cloud functionality. This paper focuses on the potential threats to users' cloud resident data and metadata and suggests possible solutions to prevent these threats. We have used UEC (Ubuntu Enterprise Cloud) Eucalyptus, which is a popular open source cloud computing software, widely used by the research community. In this work, we have simulated some of the potential attacks to users' data and metadata stored in Eucalyptus database files in order to provide the intended reader with the requisite information to be able to anticipate the grave consequences of violation of cloud users' data privacy.
Infrared Imaging System for Analysis of Blood Vessel Structure (2010)

In this paper we discuss two basic systems for analysis of blood vessels for biometric purposes. The infrared palm images that contain information about blood vessel structure are taken using 7 different near infrared wavelengths. Ten images for each wavelength have been captured and analyzed. Image quality was determined by image processing and evaluation algorithms and after that IR imaging methods are compared by the implementation and the calculated effectiveness index.

Before and After Morton (1946)

, the world will celebrate the centenary of the advent of surgical anaesthesia as a practical measure. The man was W. T. G. Morton; the country, the United States of America. As in the case of most great practical discoveries, -there had been forerunners who, with little success themselves, laid the stepping-stones without which the stream dividing the -impracticable from the practicable could not have been crossed. Many of these forerunners were British, and it is a happy coincidence that the city in which Morton's courage enabled him to succeed in the supreme test was Boston, Massachusetts-named after its spiritual parent in East Anglia. But Morton's success was not due to a lucky accident. His immediate predecessors were all American. Leake (1945) has recently suggested that it was *not by chance that the problem happened to be solved on the other side of the Atlantic, since ;in 1846 the American nation was still partly in the pioneer- ing state; and since the chief ,problems in medical practice were surgical, surgeons were always on the watch for some- thing to relieve the pain which hampered their operations.

Turn-on phenomena in optically and electrically fired thyristors (1982)

An analytical solution of the time-dependent transport equation including surface recombination and optical injection for a diffused thyristor base is presented. By means of the classical two-transistor model, the turn-on transient may be predicted. Apart from the influence of technological parameters like base width, doping profile, and diffusion length, the effect of optical versus electrical injection as well as surface recombination are discussed. Surface recombination may significantly influence the optical turn-on threshold. Despite the rigorous simplicity of the model, the dynamic turn-on behavior of an optically fired high-voltage thyristor is in very good agreement with the experiment. The data, being presented for a wide range of parameters, are useful for practical design.
TossingBot: Learning to Throw Arbitrary Objects with Residual Physics (2019)

We investigate whether a robot arm can learn to pick and throw arbitrary objects into selected boxes quickly and accurately. Throwing has the potential to increase the physical reachability and picking speed of a robot arm. However, precisely throwing arbitrary objects in unstructured settings presents many challenges: from acquiring reliable pre-throw conditions (e.g. grasp of the object) to handling varying object-centric properties (e.g. mass distribution, friction, shape) and dynamics (e.g. aerodynamics). In this work, we propose an end-to-end formulation that jointly learns to infer control parameters for grasping and throwing motion primitives from visual observations (images of arbitrary objects in a bin) through trial and error. Within this formulation, we investigate the synergies between grasping and throwing (i.e., learning grasps that enable more accurate throws) and between simulation and deep learning (i.e., using deep networks to predict residuals on top of control parameters predicted by a physics simulator). The resulting system, TossingBot, is able to grasp and successfully throw arbitrary objects into boxes located outside its maximum reach range at 500+ mean picks per hour (600+ grasps per hour with 85% throwing accuracy); and generalizes to new objects and target locations.
Psychological rejection of the transplanted organ and graft dysfunction in kidney transplant patients (2016)

Abstract: Interdisciplinary studies suggest that the mental representations of the transplanted organ may have a significant effect on the healing process. The objective of this study was to examine the representations of the transplanted organ and their relationship with emotional and mood factors, illness perceptions, and the functioning of the transplanted organ. One hundred and sixty-four kidney transplant patients were assessed using the Spielberger Anxiety Inventory, the Beck’s Depression Scale, the Posttraumatic Growth Inventory, the Brief Illness Perception Questionnaire, and the Transplanted Organ Questionnaire. Medical parameters were collected from the routine clinical blood tests (serum creatinine and estimated glomerular filtration rate levels) and biopsy results. Our most outstanding results suggest that kidney-transplanted patients’ illness representations are associated with health outcomes. The Transplanted Organ Questionnaire “psychological rejection” subscale was connected with higher serum creatinine and estimated glomerular filtration rate levels. Logistic regression analysis showed that psychological rejection subscale, Brief Illness Perception Questionnaire, and Posttraumatic Growth Questionnaire total scores were associated with graft rejection. These results may serve as a basis for the development of complex treatment interventions, which could help patients to cope with the bio-psycho-social challenges of integrating the new organ as part of their body and self. Keywords: anxiety, depression, illness representations, posttraumatic growth, psychological rejection, renal transplantation
Three-dimensional graphene networks: synthesis, properties and applications (2014)

Abstract Recently, three-dimensional graphene/graphene oxide (GO) networks (3DGNs) in the form of foams, sponges and aerogels have attracted much attention. 3D structures provide graphene materials with high specific surface areas, large pore volumes, strong mechanical strengths and fast mass and electron transport, owing to the combination of the 3D porous structures and the excellent intrinsic properties of graphene. This review focuses on the latest advances in the preparation, properties and potential applications of 3D micro-/nano-architectures made of graphene/GO-based networks, with emphasis on graphene foams and sponges.
Parameters affecting the chain extension and branching of PET in the melt state by polyepoxides (2002)

Abstract This article describes the chemical modification of polyethylene terephthalate (PET) with a variety of compounds containing reactive glycidyl group(s). Four different modifiers, namely, diglycidyl ether of bisphenol‐A (DGEBA), N , N ′‐bis[3(carbo‐2′,3′‐epoxypropoxy) phenyl] pyromellitimide (BGPM), triglycidyl glycerol (TGG), and triglycidyl isocyanurate (TGIC) were compared for their reactivity toward PET in the melt phase. It was found that the presence of tertiary nitrogen in the structure of the epoxide modifiers plays the role of in‐built catalyst for their reaction with the end groups of PET. TGIC as a modifier was selected for the detailed investigation of the simultaneously occurring degradation and chain extension/branching reactions in a batch‐melt mixer. The reactions were followed by torque changes, analyzing the products for residual carboxyl content, and by determining insoluble content. It is shown that the rate of the reactive modification of PET melt by TGIC depends upon stoichiometry, temperature, rate of shear, and the chemical composition and the molecular weight (MW) of the PET resin. In general, the results indicate an increase in melt viscosity and insoluble content, whereas an overall decrease in carboxyl content occurs, as defined by the choice of mixing conditions and stoichiometry. Analysis of the batch kinetic data can be useful to define the process requirements for carrying out the reactive modification in continuous extrusion equipment. © 2002 Wiley Periodicals, Inc.

Decorating and loading ghosts with allergens for allergen immunotherapy (2017)

More than 25% of the global population has IgE mediated allergic diseases. Allergen immunotherapy (AIT) is the only available form of treatment that alters the underlying mechanism of IgE-mediated allergic diseases. AIT is aimed at desensitizing allergic individuals by repeatedly administering disease-causing allergens over a long period of time. Despite its proven efficacy in numerous clinical trials, the effectiveness of AIT still suffers some drawbacks due to the quality of allergens used and in particular the unavailability of efficient allergen delivery systems. Several studies have demonstrated that bacterial ghosts (BG) systems can be used to display and deliver antigens to their targets for the management of diseases. However, there is no report documenting the use of BG systems for immunotherapy of IgE-mediated diseases so far. Thus, in this review, we intend to discuss the potentialities of BG systems for displaying and delivering allergens for future management of IgE-mediated diseases.
Differential scanning calorimetry evaluation of oxidation stability of docosahexaenoic acid in microalgae cells and their extracts (2013)

Summary The aim of this work was to evaluate the oxidative stability of docosahexaenoic acid ( DHA ) from A urantiochytrium limacinum SR 21 microalgae cells and in their lipidic extract by differential scanning calorimetry ( DSC ). Besides, freezing was evaluated as a strategy for microalgal DHA long‐term conservation by analysing changes in their thermal properties. As a first approach, mixtures of the most representative A. limacinum SR21‐fatty acids were evaluated in model systems. DHA and palmitic acid were the major polyunsaturated and saturated fatty acids produced by the microalgae cells, respectively. Changes in DHA /palmitic acid ratio in model systems, in cells and their lipidic extracts, were detected by DSC through shifts in the oxidation onset temperature ( OOT ) values. However, OOT values of cells and lipidic extracts could be also influenced by cellular compartmentalisation, carotenoids and other components presence. Freezing was not a good strategy for DHA long‐term conservation, as revealed by OOT values and thermal properties, which reflected the extensive changes that occurred during storage.
Machine Vision Supported Quality Control Applications in Rotary Switch Production by Using Both Process FMEA and Design FMEA (2021)

Emerging in the past few decades, Industry 4.0 has wide effects over production lines with an increasing number of novel applications. These applications implement more than one of the tools of Industry 4.0. These tools include but are not limited to internet of things (IoT), big data, cloud computing, artificial intelligence, augmented reality, virtual reality, machine to machine communication (M2M), smart robot applications, etc. The aim of these efforts is mainly to acquire smarter manufacturing systems. With spreading Industry 4.0 methodologies, the role of sensors became more important to respond to new demands. One of the most important sensor types in this sense is the camera which now has wide variants in different forms. Applying machine vision algorithms via cameras grants optimization of many critical processes. In this perspective, the quality of both product and process should be handled as a key performance indicator that may be continuously enhanced for excellence. Machine vision algorithms may be adapted to check and manage quality in designated control points on the production lines. This study focuses on the control of the quality of rotary switches that are widely used in household appliances like ovens and washing machines. Rotary switches are critical components of an appliance since they direct the flow of electricity within the product. A failure in the functionality of this component directly causes the failure of the main product. Hence, the quality rate of rotary switches should be calculated in defective parts per million (dppm) units. An intense quality control procedure is required to achieve low dppm rates during production. As a real-life application, a camera system is integrated into the rotary switch production line on a selected point. Classification algorithms are developed on a cost-effective platform to perform visual quality checks of the rotary switches and qualify as “Ok” or “Defective”. The selected point ensures a high percent check of quality criteria while enabling repair of the defective parts with minor interventions. The aim of this control is to identify a defective rotary switch as soon as possible since most of the defects are irreversible once the rotary switch is totally produced or even some processes are completed. In this case, the entire product should be set apart for scrap. Another originality of our study is applying both Process Failure Mode and Effect Analysis (PFMEA) and Design Failure Mode and Effect Analysis (DFMEA) together. There is almost no referenced study in the literature. Benchmark comparisons are conducted upon completing the integration of the new system to the production line. As a result, enhancements in the quality, cost, and production speed parameters are achieved with a cost-effective smart system. Additional capabilities are added to the system, namely data analyzing online data feeding.
ELF Electromagnetic Waves from Lightning: The Schumann Resonances (2016)

Lightning produces electromagnetic fields and waves in all frequency ranges. In the extremely low frequency (ELF) range below 100 Hz, the global Schumann Resonances (SR) are excited at frequencies of 8 Hz, 14 Hz, 20 Hz, etc. This review is aimed at the reader generally unfamiliar with the Schumann Resonances. First some historical context to SR research is given, followed by some theoretical background and examples of the extensive use of Schumann resonances in a variety of lightning-related studies in recent years, ranging from estimates of the spatial and temporal variations in global lighting activity, connections to global climate change, transient luminous events and extraterrestrial lightning. Both theoretical and experimental results of the global resonance phenomenon are presented. It is our hope that this review will increase the interest in SR among researchers previously unfamiliar with this phenomenon.
Conductive and Capacitive Properties of the Bipolar Membrane Junction Studied by AC Impedance Spectroscopy (2001)

The complete ac impedance spectrum of four bipolar membranes is analyzed both theoretically and experimentally taking into account both ionic transport and water dissociation together with the structural aspects of the bipolar junction. A theoretical model based on the Nernst−Planck and Poisson equations for the conductive and capacitive properties of the junction provides a qualitative description of the bipolar membranes for a broad range of electric currents and temperatures. Special attention is paid to the characteristics of the bipolar junction structure and the contact region between the two ion-exchange layers. It is observed that the effective area of this region increases with the electric current as mobile carriers are extracted from the interface and the layers come in closer contact.
Diffusion in binary liquid mixtures at infinite dilution (1968)

Abstract A correlation is presented for the mutual diffusion coefficient in a binary liquid system at infinite dilution. It has several advantages over previous correlations, and is recommended for diffusion in organic solvents. Some special cases where empirical correlations should be used with caution are discussed briefly.
The trajectory tracking approach-a new method for minimum distortion PWM in dynamic high-power drives (1994)

Feedforward pulsewidth modulators generate volt/spl middot/second differences between the controlling reference signal and the switched output waveform during transient operation. This dynamic modulation error is particularly pronounced at low switching frequency, e.g. with modern high-power GTO inverters. The compensation of this error is a key requirement when designing an optimal pulsewidth modulator for these applications. The trajectory tracking approach uses the steady-state trajectories of the current vector, computed from the optimal switching sequences, as templates. A tracking controller counteracts if the actual current vector deviates from this given path at transient operation. A decomposition of the current vector trajectory into its components enables, in addition, the identification of the instantaneous fundamental current, permitting the implementation of a fast current control system. Oscillograms from a 30 kW model induction motor drive demonstrate the high quality in terms of dynamic performance and minimum harmonic distortion obtained with a three-level inverter at only 200 Hz switching frequency.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Modélisation et caractérisation des effets électriques de l’intégration du Ge dans les structures Métal/High-k/SiGe (2014)

L'introduction du SiGe dans les pMOS (Bulk et FDSOI) exige un bon contrôle de la tension de seuil (VT). Ceci nécessite une extraction précise des paramètres électriques ainsi qu'une compréhension des effets électriques du Ge dans de tels dispositifs. Dans cette thèse, nous avons d'abord proposé des méthodes pour une identification précise des paramètres électriques du « gate stack »: VT, la tension de bande plate (VFB) et l'épaisseur équivalente d'oxyde (EOT). Ces méthodes ont été validées avec des simulations Poisson-Schrödinger (PS) et appliquées avec succès aux mesures. Dans un second temps, nous avons étudié les effets électriques du Ge sur les paramètres du « gate stack » des pMOS. La comparaison des caractérisations électriques (C-V) avec les simulations PS a montré un décalage supplémentaire du travail de sortie effectif qui croit avec le Ge. Des caractérisations STEM, EELS et SIMS ont prouvé que ce décalage est due à la présence de dipôles à l'interface SiGe/oxyde.
Detection of incipient left ventricular hypertrophy in mild to moderate arterial hypertension with normal electrocardiogram and echocardiogram: a new use for signal-averaged electrocardiography (2003)

SAECG can be used in the early diagnosis of LVH in hypertensive patients with normal ECG and echocardiogram.
Behavior acquisition by multi-layered reinforcement learning (2003)

Proposes multi-layered reinforcement learning by which the control structure can be decomposed into smaller transportable chunks and therefore previously learned knowledge can be applied to related tasks in a newly encountered situations. The modules in the lower networks are organized as experts to move into different categories of sensor output regions and to learn lower level behaviors using motor commands. In the meantime, the modules in the higher networks are organized as experts which learn higher level behavior using lower modules. We apply the method to a simple soccer situation in the context of RoboCup, show experimental results, and give a discussion.
RN-codes : algorithmes d'addition, de multiplication et d'élévation au carré (2004)

A property of the original Booth recoding is that the non-zero digit following --1 is necessarily -- 1 and vice versa.This allows to prove that truncating the Booth recoding of a number x is equivalent to rounding x to the nearest. P. Kornerup and J.-M. Mulleri nvestigated the positional,radix Beta, number systems sharing this rounding property and called them RN-codings.This research report is devoted to the study of addition,multiplication,and squaring algorithms for radix 2 RN-codings (i.e.Boothrecodings).We show tha tinteger arithmetic and logic units operations allow to add or multiply Booth recodings.We also describe algorithms taking advantage of the properties oft heoriginal Booth recoding to generate optimized hardware operators.
As Obesity Rates Rise, Experts Struggle to Explain Why (1998)

In the United States of the 1990s, signs of health consciousness are everywhere—except at people's waistlines. Low-fat foods, health clubs, and athletic gear have become multibillion-dollar industries, with Nike and Gatorade seemingly only slightly less ubiquitous than Microsoft. Statistics suggest that this health awareness is paying off. Since the early 1960s, blood pressure and blood cholesterol levels have been dropping, while rates of coronary heart disease mortality have declined by more than half. Given these trends, you might expect to see a trim, well-toned population, but you don't.
Experimental and Theoretical Studies on the Structure and Photoluminescent Properties of New Mononuclear and Homodinuclear Europium(III)<i>β</i>-Diketonate Complexes (2015)

Two novel europium(III) complexes, a monomer and a homodimer, with 1-(4-chlorophenyl)-4,4,4-trifluoro-1,3-butanedione (Hcbtfa) and 5-chloro-1,10-phenanthroline (cphen) ligands, formulated as [Eu(cbtfa) 3 (cphen)] and [Eu 2 (cbtfa) 4 (cphen) 2 (CH 3 O) 2 ], have been synthesized. Their structures have been elucidated by X-ray diffraction and their absorption and emission properties have been studied in the solid state. The experimental data has then been used to test the recently released LUMPAC software, a promising tool which can facilitate the design of more efficient lanthanide light-conversion molecular devices by combining ground state geometry, excited state energy, and luminescent properties calculations.
