A spreadsheet approach for early optimization of large bus switching performance (2002)

A technique for optimizing bus performance early in the design cycle is described. The technique allows packaging-related aspects of bus delay to be analyzed in a spreadsheet format. The time required for receiver inputs to pass switching threshold is described as a series of simplex expression that can be entered into a spreadsheet for comparison of various design options. It assumes CMOS or TTL-like driver devices and unterminated receivers. Parameters that can be varied include driver output characteristics, receiver thresholds, number of receivers, bus partitioning, and card transmission line characteristics. An an example, analysis of design options for a large CMOS memory bus is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On the Continuity of High Efficiency Modes in Linear RF Power Amplifiers (2009)

A novel formulation for the voltage waveforms in high efficiency linear power amplifiers is described. This formulation demonstrates that a constant optimum efficiency and output power can be obtained over a continuum of solutions by utilizing appropriate harmonic reactive impedance terminations. A specific example is confirmed experimentally. This new formulation has some important implications for the possibility of realizing broadband >10% high efficiency linear RF power amplifiers.
Optimization for Simulation: Theory vs. Practice (2002)

Probably one of the most successful interfaces between operations research and computer science has been the development of discrete-event simulation software. The recent integration of optimization techniques into simulation practice, specifically into commercial software, has become nearly ubiquitous, as most discrete-event simulation packages now include some form of “optimization” routine. The main thesis of this article, however, is that there is a disconnect between research in simulation optimization—which has addressed the stochastic nature of discrete-event simulation by concentrating on theoretical results of convergence and specialized algorithms that are mathematically elegant—and the recent software developments, which implement very general algorithms adopted from techniques in the deterministic optimization metaheuristic literature (e.g., genetic algorithms, tabu search, artificial neural networks). A tutorial exposition that summarizes the approaches found in the research literature is included, as well as a discussion contrasting these approaches with the algorithms implemented in commercial software. The article concludes with the author’s speculations on promising research areas and possible future directions in practice.

Protein arrays for autoantibody profiling and fine‐specificity mapping (2003)

Protein arrays provide a powerful approach to study autoimmune disease. Autoimmune responses activate B cells to produce autoantibodies that recognize self-molecules termed autoantigens, many of which are proteins or protein complexes. Protein arrays enable profiling of the specificity of autoantibody responses against panels of peptides and proteins representing known autoantigens as well as candidate autoantigens. In addition to identifying autoantigens and mapping immunodominant epitopes, proteomic analysis of autoantibody responses will further enable diagnosis, prognosis, and tailoring of antigen-specific tolerizing therapy.

Additive‐additive and additive‐surface interactions in lubrication (1989)

Abstract Combinations of additives are often found to exhibit antagonistic or synergistic effects compared to the performance of the individual additives. This paper reviews the state of knowledge concerning such effects. Direct interactions, where two additives combine at a molecular level, are distinguished from complementary or exclusary effects where the individual contributions of separate additives enhance or reduce overall performance but with no direct interaction. Additive interactions take place in solution and at surfaces, and both are discussed.
MIMO Power Line Communications (2014)

Despite being a well-established ingredient to many wireless systems, multiple-input-multiple-output (MIMO) signal processing has only recently been considered for broadband power line communications (PLC). Adapting multiple-antenna transmission and reception techniques to a wired medium such as the electrical grid requires solving a number of issues, both regarding the physics of electromagnetic transmission and the optimization of the signal processing strategies. In the last few years, significant steps were made to demonstrate the benefits of MIMO PLC and to develop the necessary hardware. As a result, MIMO PLC has been adopted in several broadband PLC specifications, precisely as part of ITU-T G.hn in Recommendation G.9963, and as part of the industry specification HomePlug AV2, which is backward compatible to IEEE 1901. This paper reviews important aspects of MIMO PLC, highlighting its similarities and main differences with classical wireless MIMO. It focuses first on the peculiarities of the electrical grid, with a survey of PLC channel and noise characterization in a MIMO context. It further estimates MIMO PLC channel capacity adhering to the electromagnetic compatibility regulations currently in force. In addition, MIMO signal processing techniques most suited to PLC environments are discussed, allowing for throughput predictions. It is found that eigenbeam-forming is the best choice for MIMO PLC: the full spatial diversity gain is achieved for highly attenuated channels, and maximum multiplexing gain is achieved for channels with low attenuation by utilizing all spatial streams. It is shown that upgrading from a conventional single-input-single-output PLC configuration to a 2 × 2 MIMO configuration, the throughput can be more than doubled while coverage is increased. The survey concludes with a review of specific MIMO PLC system implementations in the specifications ITU-T G.9963 and HomePlug AV2.
L'estimation du taux de chômage structurel des pays de l'OCDE (2003)

La présente étude commence par une revue du cadre conceptuel des différentes mesures du chômage structurel et des autres méthodes empiriques qui ont été utilisées pour estimer ces mesures. A partir de là, elle expose une méthode pour estimer, au moyen du filtre de Kalman, les NAIRU variables dans le temps dans un ensemble de pays de l’OCDE. Elle analyse ensuite les estimations économétriques qui en résultent et la possibilité de les affiner davantage, compte tenu des nombreuses incertitudes liées à l’estimation. Elle expose les évolutions récentes des estimations du NAIRU : elles ont régressé dans de nombreux pays au cours de la deuxième moitié des années 80, bien que le chômage effectif soit demeuré largement supérieur au NAIRU dans une majorité de pays pendant la plus grande partie de la décennie, particulièrement en Europe. En dernière partie, elle explique l’intérêt des mesures du chômage structurel pour l’analyse des évolutions de l’inflation et de la politique monétaire.

Sensitivity limits and degradations in OD8PSK (2005)

A fundamental sensitivity limit is calculated for optical differential eight-level phase-shift keying (OD8PSK). Performance degradations in practical implementations due to polarization and spectral filtering, single-ended receiving, phase offset error, and finite laser linewidth are investigated. From these results, critical OD8PSK transmitter and receiver design parameters are extracted.
Metalworking emulsions from industrial vegetable oils (2008)

Abstract In the present work, an attempt has been made to develop the indigenous formulation for metalworking lubricants by replacing mineral oils partially with non‐edible industrial oils like rapeseed and karanja oil. Metalworking formulations consist of vegetable oil, mineral oil, an emulsifier and commercial additives for better performance. Non‐edible vegetable oils such as karanja and rapeseeds are renewable, biodegradable and cheaper than synthetic fluids. The constituent vegetable oils and mineral oils were evaluated for physico‐chemical characteristics and blended as per the saponification value and viscosity requirements of the reference oils. The so formulated oils are taken as 5% oil‐in‐water emulsion and tested for lubricity, load bearing capacity, particle size distribution, wear test, weld load test and plate‐out test. Performance of all formulated oils was compared with that of the reference oils, and optimized to meet the market requirements. Copyright © 2008 John Wiley & Sons, Ltd.
Personalized Event Recommendations Using Social Networks (2015)

In recent years we have observed a significant increase in the popularity of location-based social networks for exchanging news and experiences, sharing location information, or publishing real world events. One important challenge in such networks is to understand human crowd mobility behavior based on user social activities and interactions. In this paper we introduce PRESENT, our middleware that utilizes a Mixed Markov Model to extract the behavioral patterns of the users in social groups, to make personalized event recommendations. Our detailed experimental evaluation, using data from the Meet up location-based social network, illustrates that our approach is efficient, practical and achieves an average prediction for the user attendance of over 73%.

Hydraulic Fracturing of Horizontal Wells: An Update of Design and Execution Guidelines (1996)

Abstract Thousands of horizontal wells have been drilled world-wide over the last ten years. Most of them are completed openhole and do not produce as well as expected. In their design phase, adverse reservoir and wellbore effects are often underestimated, such as permeability anisotropy, well stand-off, fonnation damage, formation face damage, and sand control screen plugging. Recent statistical surveys of the production of openhole horizontal wells have confirmed that actual performances are disappointing. They are leading to major re-evaluations of drilling and completion strategies in many present reservoir developments. In offshore environments where a limited number of slots are available, horizontal wells remain the best choice. However they are increasingly cased, cemented, perforaled and stimulated, in order to alleviate the problems affecting openhole wells. This paper describes how this new trend is expanding in the North Sea, and gives all necessary guidelines to successfully design and execute multiple fracturing treatments in horizontal wells. Production and treatment cost estimates are provided for all cases of fracture orientation vs. the wellbore. Radial flow effects in non-collinear geometry are detailed and Tip Screen Out (TSO) designs recommended.
Optimal ways for companies to use Facebook as a marketing channel (2013)

Purpose Social media has increased as a marketing channel, and Facebook is the biggest social media company globally. Facebook contains both positive and negative information about companies; therefore, it is important for companies to manage their Facebook page to best serve their own interests. Although most users are familiar with business and marketing activities on Facebook, they use it primarily for fun and personal purposes. The most effective methods for companies to use Facebook have not been clear. The personal nature of Facebook presents unique challenges for companies by raising ethical and social responsibility issues that are important to users. The purpose of this paper is to discover how companies can optimize their use of Facebook as a marketing channel. Design/methodology/approach A survey was conducted. The respondents were 158 users of Facebook in Sweden; complete answers were provided by all respondents. In a series of specific questions and comments, the respondents were asked to describe an optimal marketing solution on Facebook for companies. They rated different functions, which were illustrated with pictures, to help in the cognitive process and to avoid misunderstandings. Findings Most users who have an opinion on the issue accept marketing on Facebook, but only in the right amount. There are basically two groups: those who think that companies have no place on Facebook and those who want companies to be active on Facebook. The latter group emphasizes the importance of meaningful posts without unsolicited sales messages, and would prefer to search for the companies themselves rather than being bombarded by company messages. By far, status updates and pictures/images were found to be the most important functions to respondents. Research limitations/implications The sample consisted of only Swedish users. Another limitation was that, since many Facebook users do not normally think about the implications of being exposed to marketing on Facebook, they have difficulty taking a position on many issues related to the service. Practical implications The results give companies a clear idea of how to effectively use Facebook in their marketing efforts. Originality/value A large number of companies are currently asking themselves, “How can we use Facebook in an optimal way?” The results in this study answer this question and lead directly to saving time and resources for these companies.

High-dose chemoradiotherapy and anti-B-cell monoclonal antibody-purged autologous bone marrow transplantation in mantle-cell lymphoma: no evidence for long-term remission. (1998)

ABMT using cyclophosphamide/TBI conditioning may at best be effective in only a small fraction of patients with relapsed MCL. The lack of plateau with a median follow-up time of 24 months suggests cure may not be achievable. The role of this therapy in patients in first remission requires more study using better induction therapy to enhance the CR rate before ABMT.
Use of Solid-Phase Microextraction for the Quantitative Determination of Herbicides in Soil and Water Samples (2000)

An in-depth study of SPME optimization and application has been made, considering not only aqueous (surface water and groundwater samples) but also the more complex soil samples. Seven herbicides widely used in the area of study have been selected including five triazine herbicides (atrazine, simazine, terbumeton, terbuthylazine, terbutryn), molinate, and bromacil. linearity range was between 0.1 and 10 ng/mL and the repeatability below 10% when applying the optimized SPME procedure to water samples. Reproducibility was found to be lower than 20% at the 1 ng/mL level, and the limits of determination in environmental water samples using GC/MS (SIM mode) were well below 0.1 ng/mL (values ranging from 10 to 60 ng/L). Extraction of selected herbicides from soil was carried out by microwave-assisted solvent extraction using methanol in screw-capped vials, leading to recoveries over 80% in spiked soil samples at the 5-200 ng/g level. SPME application over methanolic soil extracts required a 10-fold dilution with distilled water. The recommended procedure was found to be fully applicable for quantitative determination of selected herbicides in soils containing low organic matter content with coefficients of variation below or around 10% and limits of determination ranging from 1 to 10 ng/g. Both procedures were applied to real-world surface water and soil samples where several pesticides were detected including atrazine, simazine, terbuthylazine, and molinate.
Logical authentication method (1986)

A logical authentication test requires no special hardware. As a proof of identity, the accessor is required to know or to use secret information. In a generalized model of logical authentication, the user learns an encryption algorithm whose functional description is secret. This model includes new tests of secret knowledge which induce larger forgery costs in certain environments than methods currently in wide-spread use.
The use of medical grade honey in clinical practice (2008)

In the current healthcare environment, clinicians are increasingly under pressure to use wound care products that are cost-effective. This includes products that can be used in a variety of wounds to achieve different outcomes, depending on the wound-bed requirements. Medical grade honey has emerged as a product that can achieve a variety of outcomes within the wound and is safe and easy to use. This article reviews the use of a medical grade honey (Medihoney) in various clinical applications, with a view to placement on the wound care formulary in both primary and secondary care. It provides an in-depth account of case studies featured in a poster presentation at the 2008 European Wound Management Association meeting in Lisbon, Portugal.
Strategies for Enhancing the Consonant to Vowel Intensity Ratio With In the Ear Hearing Aids (1991)

Numerous investigators have suggested that increasing the consonant to vowel intensity ratio (CVR) may improve speech intelligibility. This investigation was designed to determine the extent to which analog circuits, small enough to fit into in the ear hearing aids, can increase the CVR, and whether CVR enhancement is of benefit to hearing-impaired listeners. Real ear CVRs, calculated from real ear recordings of nonsense syllables, were obtained from eight hearing-impaired listeners. Recordings from each listener were obtained through each of four hearing aid circuits: (1) an adaptive high-pass filter; (2) a faster acting adaptive high-pass filter; (3) the fast-acting adaptive high-pass filter with expansion; and (4) an infinite amplitude clipper. The amount of CVR enhancement was compared to performance of the subjects with a NST speech recognition task. Subjects also ranked the four circuits for amount of consonant emphasis provided. Results indicated that the four hearing aid circuits increased the real ear CVR by 4 to 6 dB, relative to unaided. Aided CVR varied, however, across circuits and between fricative and stop consonants. Performance on the NST recognition task was generally consistent with the amount of CVR increase provided. Rank ordering for consonant emphasis was consistent with aided CVR for stop consonants, but not for fricatives.
