Nd-YAG laser welding of bare and galvanised steels (1989)

<div class="htmlview paragraph">Until recently, one of the problems that has held back the introduction of lasers into car body fabrication has been the difficulty of integrating the lasers with robots. Flexible beam transmission systems for CO<sub>2</sub>lasers require a large number of heavy optics that must be kept accurately aligned and mounted on a robust, heavy robot, that may not have the positional accuracy necessary for laser welding. Nd-YAG laser beams can be transmitted through fibre optics which, as well as being considerably easier to manipulate than a mirror system, can be mounted on more lightweight accurate robots. Although previously only available at low powers, recent developments in Nd-YAG laser technology mean that lasers of up to 1kW average power will soon be available, coupled to a fibre optic beam delivery system. The increasing usage of zinc coated steels in vehicle bodies has led to welding problems using conventional resistance welding as well as CO; laser welding. The use of Nd-YAG lasers may be able to overcome these problems.</div> <div class="htmlview paragraph">This paper outlines work carried out at The Welding Institute on a prototype Lumonics 800W pulsed Rd-YAG laser to investigate its welding characteristics on bare and zinc coated car body steels. Lap welds were made in 0.7mm thick materials at a range of welding speeds, pulse energies, repetition rates and pulse widths, using conventional focusing optics without a fibre. Full penetration welds were made at speeds up to 0.5m/min, which were visually good in the bare steels. Welds in the coated steels were slightly undercut but did not contain any of the surface blowholes that are often found in CO; laser welds in coated steels. These early results show that an 800W pulsed Nd-YAG laser can be used for welding car body steels and that, although the welding speeds are much lower than those achievable with a CO<sub>2</sub>laser, the consistency of welds in zinc coated steels is considerably higher.</div>
JITGuard (2017)

Memory-corruption vulnerabilities pose a serious threat to modern computer security. Attackers exploit these vulnerabilities to manipulate code and data of vulnerable applications to generate malicious behavior by means of code-injection and code-reuse attacks. Researchers already demonstrated the power of data-only attacks by disclosing secret data such as cryptographic keys in the past. A large body of literature has investigated defenses against code-injection, code-reuse, and data-only attacks. Unfortunately, most of these defenses are tailored towards statically generated code and their adaption to dynamic code comes with the price of security or performance penalties. However, many common applications, like browsers and document viewers, embed just-in-time compilers to generate dynamic code. The contribution of this paper is twofold: first, we propose a generic data-only attack against JIT compilers, dubbed DOJITA. In contrast to previous data-only attacks that aimed at disclosing secret data, DOJITA enables arbitrary code-execution. Second, we propose JITGuard, a novel defense to mitigate code-injection, code-reuse, and data-only attacks against just-in-time compilers (including DOJITA). JITGuard utilizes Intel's Software Guard Extensions (SGX) to provide a secure environment for emitting the dynamic code to a secret region, which is only known to the JIT compiler, and hence, inaccessible to the attacker. Our proposal is the first solution leveraging SGX to protect the security critical JIT compiler operations, and tackles a number of difficult challenges. As proof of concept we implemented JITGuard for Firefox's JIT compiler SpiderMonkey. Our evaluation shows reasonable overhead of 9.8% for common benchmarks.
[Ten year's experience with combined hepatitis A and B vaccine]. (2008)

Hepatitis A and B are still a serious global public health problem. Monovalent vaccines against hepatitis A and B have been available on the European but also on the Czech market for long time. Since 1997 different formulations and immunization schedules of the first combined vaccine against both diseases have been gradually introduced into clinical practice. Twinrix Adult (with conventional and accelerated schedules), and Twinrix Paediatric are available for all patients in Europe and also in USA. AmBirix as a two scheduled vaccine for age from 1-15years is licensed in Europe. These vaccines offer fewer injections for satisfactory protection against hepatitis A and B and an excellent safety and reactogenicity profile in comparison to monovalent vaccines. This review is dominantly focused on immunogenicity, safety and reactogenicity data of the vaccine, which are available now for more than 10 years.
Multi-stimuli responsive macromolecules and their assemblies (2013)

In this review, we outline examples that illustrate the design criteria for achieving macromolecular assemblies that incorporate a combination of two or more chemical, physical or biological stimuli-responsive components. Progress in both fundamental investigation into the phase transformations of these polymers in response to multiple stimuli and their utilization in a variety of practical applications are highlighted. Using these examples, we aim to explain the origin of employed mechanisms of stimuli responsiveness which may serve as a guideline to inspire future design of multi-stimuli responsive materials.
A taxonomy of model‐based testing approaches (2011)

SUMMARY Model‐based testing (MBT) relies on models of a system under test and/or its environment to derive test cases for the system. This paper discusses the process of MBT and defines a taxonomy that covers the key aspects of MBT approaches. It is intended to help with understanding the characteristics, similarities and differences of those approaches, and with classifying the approach used in a particular MBT tool. To illustrate the taxonomy, a description of how three different examples of MBT tools fit into the taxonomy is provided. Copyright © 2011 John Wiley & Sons, Ltd.
Low-SWaP coincidence processing for Geiger-mode LIDAR video (2015)

Photon-counting Geiger-mode lidar detector arrays provide a promising approach for producing three-dimensional (3D) video at full motion video (FMV) data rates, resolution, and image size from long ranges. However, coincidence processing required to filter raw photon counts is computationally expensive, generally requiring significant size, weight, and power (SWaP) and also time. In this paper, we describe a laboratory test-bed developed to assess the feasibility of low-SWaP, real-time processing for 3D FMV based on Geiger-mode lidar. First, we examine a design based on field programmable gate arrays (FPGA) and demonstrate proof-of-concept results. Then we examine a design based on a first-of-its-kind embedded graphical processing unit (GPU) and compare performance with the FPGA. Results indicate feasibility of real-time Geiger-mode lidar processing for 3D FMV and also suggest utility for real-time onboard processing for mapping lidar systems.
Massive acetaminophen ingestion with early metabolic acidosis and coma: treatment with IV NAC and continuous venovenous hemodiafiltration (2010)

The average clearance of acetaminophen by CVVHD was 2.53 L/h, with removal of 24 g of acetaminophen over 16 h. As NAC is effective in preventing hepatic injury after acute acetaminophen overdose, the role of dialysis or CVVHD is limited.
RESPONSE OF CULTURED MACROPHAGES TO <i>MYCOBACTERIUM TUBERCULOSIS</i>, WITH OBSERVATIONS ON FUSION OF LYSOSOMES WITH PHAGOSOMES (1971)

The cytological response to the ingestion of tubercle bacilli by cultured mouse peritoneal macrophages has been studied by electron microscopy. Methods included a quantitative assessment based on systematic surveying of cell profiles, and of phagosomes and their contained bacteria, encountered in thin sections; classification of the sectioned bacteria into visibly damaged and apparently intact categories; prelabeling of dense granules (secondary lysosomes) with ferritin as an aid to identifying the occurrence and frequency of phagosome-lysosome fusion; and monitoring of bacterial growth and viability by light microscopy and cultural counts. The situations studied were as follows: progressive infection with the multiplying virulent strain H37Rv; ingestion of the same strain previously inactivated by gamma radiation; infection with an attenuated strain (BCG); and a stabilized virulent infection induced by the surfactant Macrocyclon. In the bacterial suspensions used routinely for inoculation, about half the bacilli were viable, matching closely the proportions of intact and damaged organisms identified with the electron microscope. In the inoculated macrophages, some phagosomes containing intact bacilli and others containing damaged bacilli were always to be found; but the proportion of organisms scored as damaged increased, and that of intact organisms decreased, in situations where the population as a whole had been rendered nonviable before inoculation, or where they became so intracellularly as in the late stages of a BCG infection. Evidence of fusion of ferritin-marked lysosomes with some bacterium-containing phagosomes was obtained in all experiments, but a significant difference was regularly observed according to whether the bacilli were damaged or intact. Virtually all phagosomes containing damaged bacilli showed signs of fusion; but when many phagosomes were present containing apparently intact organisms (as with actively multiplying strain H37Rv or with this strain held at a steady level of viability by Macrocyclon, and also with strain BCG at an early stage of that infection), signs of fusion of lysosomes with these phagosomes were infrequent. From these findings it is inferred that intracellular survival of M. tuberculosis in cultured macrophages is associated with a tendency to nonfusion of dense granules with the phagosome, thus avoiding direct exposure of the bacilli to the contents of these organelles. It is suggested, further, that fusion of dense granules with the phagosome, leading to digestion, is determined by recognition of the bacillus as nonviable. The possibility is discussed that the cytological response to different mycobacterial infections may reflect differences of a basic nature between facultative and obligate intracellular parasitism.
The ABR congestion control by the least squares estimation of spatial distribution of sources (2002)

In this paper, control of ATM ABR traffic is considered for a simple system with a single bottleneck switch and several sources at different distances from the switch. User population is partitioned into delay zones according to the round trip delays between the switch and the zones. The switch employs an ER (explicit rate) control. The contribution of input traffic from a source is upperbounded by the ER, which was specified by the switch round trip delay earlier. The aggregate input rate into the switch then becomes a weighted sum of past ER's, where the weights are determined by the number of sources and their levels of activities in respective zones. Given the history of aggregate input rates and ER's, the switch is able to estimate the traffic intensities from individual zones. The results from several scenarios demonstrate that the least squares estimation of the weight distribution across zones can provide the convergence in the maximum round trip delay.
A flexible remote user authentication scheme using smart cards (2002)

In 1999, Hwang and Li proposed a new user authentication scheme using smart cards. The scheme does not need any password or verification table. Later, Sun proposed an efficient remote use authentication scheme to improve the efficiency of the Hwang-Li scheme. However, these two schemes do not allow users to freely choose and change their passwords. In this article, we shall propose a simple and efficient remote user authentication scheme that allows users to freely choose and change their passwords without significantly increasing the computation cost.
Change Detection and Notification Method of the Rich Internet Application Content (2018)

The paper presents the techniques for supervised information extraction and change notification of the Web resources. The method uses the combination of supervised wrapping or Web scraping techniques integrated to a browser as an extension. A prototype was developed to provide the proof of concept validation and moreover to identify the pros and cons of proposed solution. The paper focuses on the core methods being used for structured data extraction from Web resources and on notification of the users in the most appropriate manner. The approach has a potential to share marked Web elements among users taking advantages of the collaborative annotation. The paper concludes with the research challenges stumbled on during the process on method design.
Influence of Water Vapor Addition on the Surface Modification of Polyethylene in an Argon Dielectric Barrier Discharge (2013)

In this paper, water vapor up to 41% is added to an argon dielectric barrier discharge at medium pressure to profoundly investigate the effect of water vapor addition on the surface modification of polyethylene (PE). Contact angle measurements show that the wettability of PE significantly increases after a pure argon plasma treatment. However, the addition of water vapor to the argon feeding gas can give an extra 30% decrease in water contact angle. This extra decrease is due to the incorporation of additional oxygen containing groups such as CO, CO, OCO, and OCO. AFM results reveal that the surface roughness of PE only increases for plasma treatments with no or low water vapor concentrations. All this indicates that a water vapor based plasma can be an excellent tool for the surface activation of PE.
Quality-aware neural complementary item recommendation (2018)

Complementary item recommendation finds products that go well with one another (e.g., a camera and a specific lens). While complementary items are ubiquitous, the dimensions by which items go together can vary by both product and category, making it difficult to detect complementary items at scale. Moreover, in practice, user preferences for complementary items can be complex combinations of item quality and evidence of complementarity. Hence, we propose a new neural complementary recommender Encore that can jointly learn complementary item relationships and user preferences. Specifically, Encore (i) effectively combines and balances both stylistic and functional evidence of complementary items across item categories; (ii) naturally models item latent quality for complementary items through Bayesian inference of customer ratings; and (iii) builds a novel neural network model to learn the complex (non-linear) relationships between items for flexible and scalable complementary product recommendations. Through experiments over large Amazon datasets, we find that Encore effectively learns complementary item relationships, leading to an improvement in accuracy of 15.5% on average versus the next-best alternative.
Clinical study for the evaluation of mental concentration enhancing effects of an ayurveda drug and Panchakarma in children (2016)

Poor mental concentration is being identified as one of the important cause of academic under achievement.Ayurveda may prove beneficial in improving mental concentration in a safe and effective way. To provide an update of the practical application of Ayurveda compound Kalyana leha and shirodhara procedure in management of poor mental concentration in children, a randomized placebo control study was done. Group A with Kalyana leha have shown highly significant improvement in IQ level, reaction time and on Wechsler Intelligence Scale For Children (WISC) scale, Group B as placebo group have non-significant improvement in all parameters whereas Group C with Shirodhara Procedure was also significant in all parameters but in intergroup comparison Group A was more significant than Group B and C both. Mental concertation can be enhanced effectively with Ayurveda drugs and procedures which can prove to be a key for better school performance among children.
Meta Model Driven Framework for the Integration and Extension of Application Components (2004)

Generally software is seen as something that is purchased off-the-shelf. However, this perception is incorrect, as off-the-shelf software represents only 15 percent of all software development. The remaining 85 percent represents specialized software developed for large organizations to help them meet their unique requirements. The competitive nature of such organizations typically results in rapidly evolving software requirements. Component-based software engineering techniques lend themselves favorably to the development of reconfigurable software. However, component integration and reconfiguration complexity issues make component-oriented programs difficult to maintain, expand and widely reuse. In this paper we propose a distributed Meta model driven framework that eases software customization and redirects this task away from the software developer to the software user. Through the use of an application generator tool we realize the concept of ‘model once, generate anywhere’.
A New Approach to Secure Distributed Storage, Sharing and Dissemination of Digital Image (2006)

In this paper, we present a novel technique for secure distributed storage and dissemination of digital images using Chinese remainder theorem (CRT). The proposed technique not only involves significantly low computational complexity but also imposes various stages of difficulty to an intruder who intends to extract the original image from the encrypted sub-blocks. The proposed CRT-based technique is, therefore, useful for secure archival of large volume of image data and sharing of digital images by the users from different locations
A memristor-based TCAM (ternary content addressable memory) cell (2012)

This paper presents a Ternary Content Addressable Memory (TCAM) cell that employs memristors as storage element. The TCAM cell requires two memristors in series to perform the traditional memory operations (read and write) as well as the search and matching operations for TCAM; this memory cell is analyzed with respect to different features (such as transistor sizing and voltage threshold) of the memristors to process fast and efficiently the ternary data. A comprehensive simulation based assessment of this cell is pursued by HSPICE.
On the Modeling of Vertical Permeability Barriers in Single-Well Simulation Models (1989)

Summary This paper presents stochastic descriptive schemes for explicit and implicit modeling of vertical permeability barriers in single-well simulation studies. The drainage volume of the well to be simulated is first partitioned into two regions: one explicit region ("explicit" because actual barriers—e.g., shales of various sizes—are placed within the grid) and one implicit region ("implicit" because the effects of the discontinuous shales are averaged into an effective vertical permeability). Second, the shales are converted into vertical transmissibility modifiers and included in the data-input stream, along with the effective vertical permeabilities calculated for the implicit regions. The methodology developed is illustrated by application to a North Sea reservoir with a thin oil column sandwiched between a gas cap and an active aquifer. In this reservoir, trustworthy predictions of oil, gas, and water production rates through time are of fundamental importance. In fact, the field-development decision may be swayed one way or another, depending on how long the gas and water production may be suppressed (aided by shales) for a reasonably high (and sustainable) oil-production rate.
The effect of protamine on antibiotic action against Staphylococcus epidermidis biofilms. (1991)

Infection associated with medical devices may involve bacterial biofilms, a possible cause of antibiotic resistance. Protamine, a basic polypeptide, depresses the metabolic activity of Staphylococcus epidermidis in a standardized biofilm assay. The resistance of the biofilm preparations to many antibiotics, with the sole exception of rifampin, was confirmed. Rifampin produced predominant lysis and killing with foci of genetically programmed resistance. The combination of protamine with antibiotics produced no change, except the combination with rifampin where clear classic synergism with a totally bactericidal outcome was demonstrated. Protamine is a member of the larger family of charged polycations, some of which possess membrane potential altering properties, possibly interfering with the protective nature exhibited by the negatively charged bacterial biofilm matrix.
001: On an Absolute Criterion for Fitting Frequency Curves. (1912)

1. If we set ourselves the problem, in its essence one of frequent occurrence, of finding the arbitrary elements in a function of known form, which best suit a set of actual observations we are met at the outset by an arbitrariness which pears to invalidate any results we may obtain. In the general problem of fitting a theoretical curve, either to an observed curve, or to an observed series of ordinates, it is, indeed, possible to specify a number of different standards of conformity between the observations and the theoretical curve, which definitely lead to different though mutually approximate results. This mutual approximation, though convenient in practice in that it allows a computer to make a legitimate choice of the method which is arithmetically simplest, is harmful from the theoretical standpoint as tending to obscure the practical discrepancies, and the theoretical indefiniteness which actually exist.
THE USE OF LINES OF NONEXTENSION TO IMPROVE MOBILITY IN FULL-PRESSURE SUITS (1964)

Abstract : An important objective in the development of a fullpressure suit for a human being is to permit the wearer full mobility without interfering with physical capability. Although the human skin is stretched during body motion, there is virtually no stretch along certain lines, here called 'lines of nonextension'. The investigation was un dertaken to determine the efficacy of utilizing lines of nonextension to provide natural mobility and minimal ballooning in full-pressure suits. The program of investigation pursued was: (1) to map out these lines of nonextension, (2) to test whether string elements of high elastic modulus, a connected network, could be laid along these lines of nonestension without providing any constraint to mobility, (3) to obtain a highly mobile pressure-retaining layer to be constrained by the net, and (4) to construct and demonstrate an entire pressure-retaining garment system that makes use of all necessary layers and string elements in a completely connected, netted covering for the body, with minimal constraint to mobility up to 5 psi. A mobile, pressure-retaining garment was developed by building each structural, functional layer into the composite garment in accordance with the basic design theory.
