    The paper describes the, expert panel methodology developed for evaluating the preliminary results in the STUK's RI-ISI (Risk-Informed In-Service Inspection) pilot study. The aim of the expert panel was to achieve a balanced utilisation of deterministic information on degradation mechanisms and probabilistic information on pipe break consequences. For systems considered in the pilot study, the preliminary segmentation, and the segment categorisation were reviewed. The expert panel can be seen both as quality assurance or critical review of the results and as a decision support for the final categorisation of segments according to the severity of degradation and consequences of pipe break. The expert panel discussion resulted in some changes in segmentation and categorisation. (author)

    1997-05-01

    When members were first canvassed for participation in the Vadose Zone Expert Panel the stated purpose for convening the Panel was to review a controversial draft report, the SX Tank Farm Report. This report was produced by a DOE Grand Junction Project Office (GJPO) contractor, RUST Geotech, now MACTEC-ERS, for the DOE Richland Office (DOERL). Three meetings were planned for June, July and August, 1995 to review the draft report and to complete a Panel report by mid-September. The Expert Panel has found its efforts confounded by various non-technical issues. The Expert Panel has chosen to address some of the non-technical issues in this Preface rather than to dilute the technical discussion that follows in the body of this independent expert panel status report (Panel Report). Rather than performing a straightforward manuscript review, the Panel was asked to resolve conflicting interpretations of gamma-ray logging measurements performed in vadose zone boreholes (drywells) surrounding the high-level radioactive wastes of the SX tank farm. There are numerous and complex technical issues that must be evaluated before the vertical and radial extent of contaminant migration at the SX tank farm can be accurately assessed. When the Panel first met in early June, 1996, it quickly became apparent that the scientific and technical issues were obscured by policy and institutional affairs which have polarized discussion among various segments of the Hanford organization. This situation reflects the kinds of institutional problems described separately in reports by the National Research Council of the National Academy of Sciences (NAS/NRC), The Hanford Tanks Environmental Impacts and Policy Choices and BmTiers to Science: Technical Management of the Department of Energy Environmental Remediation Program. The Vadose Zone Characterization Program, appears to be caught between conflicting pressures and organizational mandates, some imposed from outside DOE-RL and some self

    The report describes the expert panel methodology developed for supporting risk-informed decision making. The aim of an expert panel is to achieve a balanced utilisation of information and expertise from several disciplines in decision-making including probabilistic safety assessment as one decision criterion. We also summarise the application of the methodology in the STUK's RI-ISI (Risk-Informed In-Service Inspection) pilot study, where the expert panel approach was used to combine the deterministic information on degradation mechanisms and probabilistic information on pipe break consequences. The expert panel served both as a critical review of the preliminary results and as a decision support for the final definition of risk categories of piping. (orig.)

    This paper presented the results of a study conducted to review the current literature available on the perceived health effects of wind turbines. The review was conducted by a multidisciplinary panel comprised of audiologists, medical doctors, and acoustical professionals from throughout the world. The document was prepared as a reference point for legislators, regulators and other stakeholders in need of information about wind turbine sounds. A large body of peer-reviewed literature on sound and health effects in general were reviewed in order to assess the plausible biological effects of exposure to wind turbine sound. A review of potential environmental exposures associated with wind turbine operations was conducted. Results of the study indicated that there is no evidence that the sounds emitted by wind turbines have any direct adverse physiological effects, and that the ground-borne vibrations from wind turbines are too weak to be detected or to affect humans. The panel concluded that the sounds from wind turbines can not plausibly have direct adverse health consequences. 126 refs., 3 tabs., 4 figs., 5 appendices.

    Full Text Available Abstract Background Demand for rehabilitation services is expected to increase due to factors such as an aging population, workforce pressures, rise in chronic and complex multi-system disorders, advances in technology, and changes in interprofessional health service delivery models. However, health human resource (HHR strategies for Canadian rehabilitation professionals are lagging behind other professional groups such as physicians and nurses. The objectives of this study were: 1 to identify recruitment and retention strategies of rehabilitation professionals including occupational therapists, physical therapists and speech language pathologists from the literature; and 2 to investigate both the importance and feasibility of the identified strategies using expert panels amongst HHR and education experts. Methods A review of the literature was conducted to identify recruitment and retention strategies for rehabilitation professionals. Two expert panels, one on Recruitment and Retention and the other on Education were convened to determine the importance and feasibility of the identified strategies. A modified-delphi process was used to gain consensus and to rate the identified strategies along these two dimensions. Results A total of 34 strategies were identified by the Recruitment and Retention and Education expert panels as being important and feasible for the development of a HHR plan for recruitment and retention of rehabilitation professionals. Seven were categorized under the Quality of Worklife and Work Environment theme, another seven in Financial Incentives and Marketing, two in Workload and Skill Mix, thirteen in Professional Development and five in Education and Training. Conclusion Based on the results from the expert panels, the three major areas of focus for HHR planning in the rehabilitation sector should include strategies addressing Quality of Worklife and Work Environment, Financial Incentives and Marketing and Professional

  7. Treatment Guidelines for Preoperative Radiation Therapy for Retroperitoneal Sarcoma: Preliminary Consensus of an International Expert Panel

    International Nuclear Information System (INIS)

    Purpose: Evidence for external beam radiation therapy (RT) as part of treatment for retroperitoneal sarcoma (RPS) is limited. Preoperative RT is the subject of a current randomized trial, but the results will not be available for many years. In the meantime, many practitioners use preoperative RT for RPS, and although this approach is used in practice, there are no radiation treatment guidelines. An international expert panel was convened to develop consensus treatment guidelines for preoperative RT for RPS. Methods and Materials: An expert panel of 15 academic radiation oncologists who specialize in the treatment of sarcoma was assembled. A systematic review of reports related to RT for RPS, RT for extremity sarcoma, and RT-related toxicities for organs at risk was performed. Due to the paucity of high-quality published data on the subject of RT for RPS, consensus recommendations were based largely on expert opinion derived from clinical experience and extrapolation of relevant published reports. It is intended that these clinical practice guidelines be updated as pertinent data become available. Results: Treatment guidelines for preoperative RT for RPS are presented. Conclusions: An international panel of radiation oncologists who specialize in sarcoma reached consensus guidelines for preoperative RT for RPS. Many of the recommendations are based on expert opinion because of the absence of higher level evidence and, thus, are best regarded as preliminary. We emphasize that the role of preoperative RT for RPS has not been proven, and we await data from the European Organization for Research and Treatment of Cancer (EORTC) study of preoperative radiotherapy plus surgery versus surgery alone for patients with RPS. Further data are also anticipated pertaining to normal tissue dose constraints, particularly for bowel tolerance. Nonetheless, as we await these data, the guidelines herein can be used to establish treatment uniformity to aid future assessments of efficacy

  13. Analysis of core damage frequency from internal events: Expert judgment elicitation. Part 1: Expert panel results. Part 2: Project staff results

    International Nuclear Information System (INIS)

    Quantitative modeling techniques have limitations as to the resolution of important issues in probabilistic risk assessment (PRA). Not all issues can be resolved via the existing set of methods such as fault trees, event trees, statistical analyses, data collection, and computer simulation. Therefore, an expert judgment process was developed to address issues perceived as important to risk in the NUREG-1150 analysis but which could not be resolved with existing techniques. This process was applied to several issues that could significantly affect the internal event core damage frequencies of the PRAs performed on six light water reactors. Detailed descriptions of these issues and the results of the expert judgment elicitation are reported here, as well as an explanation of the methodology used and the procedure followed in performing the overall elicitation task. The process is time-consuming and expensive. However, the results are very useful, and represent an improvement over the draft NUREG-1150 analysis in the areas of expert selection, elicitation training, issue selection and presentation, elicitation of judgment and aggregation of results. The results are presented in two parts. Part documents the expert panel elicitations, where the most important issues were presented to a panel of experts convened from throughout the nuclear power risk assessment community. Part 2 documents the process by which the project staff performed expert judgment on other important issues, using the project staff as panel members. (author)

  15. Microbiological specifications and testing methods for irradiated food. Report of a panel of experts

    International Nuclear Information System (INIS)

    In recent years there has been increased interest in the development of food items processed by means of ionizing radiation, wherever that form of preservation might show advantage over other methods. If this method becomes successful, the various items will be commercially exploited; it would then be convenient to have similar legislation in many countries of the world to control this type of processing and to facilitate international trade. To gather information and suggestions in order to devise legislation on irradiated food, a Joint FAO/IAEA/ WHO Expert Committee on the Technical Basis for Legislation on Irradiated Food was held in Rome on 21-28 April 1964. The Committee's report, 'The technical basis for legislation on irradiated food', was published as FAO Atomic Energy Series No.6 and WHO Technical Series No. 316. The Committee's terms of reference were to consider the available evidence on the effect on food of treatment with ionizing radiation in the context of wholesomeness and safety for consumption. Nutritional aspects were taken into account, but microbiological safety and microbiological methods for irradiated food were excluded since these subjects were believed to be too broad for adequate coverage in the working time available at the meeting. However, realizing the importance of radiation microbiology and the need for guidance in formulating regulations in this field, the committee drafted the following recommendation: 'The methods and standards used to ensure the microbiological safety of the irradiated product should, as a matter of urgency, be subject to review by competent international bodies in order that internationally acceptable methods and standards may be agreed upon'. In response to this recommendation an FAO/IAEA Panel on Microbiological Standards and Testing Methods for Irradiated Food was held in Vienna on 22-26 June 1965, in collaboration with the International Association of Microbiological Societies (IAMS).

    Dengue vaccines are currently in development and policymakers need appropriate economic studies to determine their potential financial and public health impact. We searched five databases (PubMed, EMBASE, LILAC, EconLit, and WHOLIS) to identify health economics studies of dengue. Forty-three manuscripts were identified that provided primary data: 32 report economic burden of dengue and nine are comparative economic analyses assessing various interventions. The remaining two were a willingness-to-pay study and a policymaker survey. An expert panel reviewed the existing dengue economic literature and recommended future research to fill information gaps. Although dengue is an important vector-borne disease, the economic literature is relatively sparse and results have often been conflicting because of use of inconsistent assumptions. Health economic research specific to dengue is urgently needed to ensure informed decision making on the various options for controlling and preventing this disease. PMID:21363989

    2007-12-01

    The research from the Expert Panel on Electronic Media and Youth Violence makes a compelling case for why educators and education policymakers should care about the effects of media on youth behavior, and the growing phenomenon of Internet bullying and harassment. The ability of the U.S. education system to respond is limited not only by competing instructional priorities but also by the governance structure of the education system itself. The federal role is limited to a proportionally small amount of funding for states and schools, to raising public awareness, and to providing research and data. States can set priorities, make requirements, and direct funding. Districts and schools ultimately have the most control over prevention program selection and setting social and behavioral norms. Key implications of the panel's research for educators and education policymakers include: Internet bullying is correlated with school behavior problems; Internet bullying behavior may peak in middle school; Internet bullying shares common predictors with verbal and, to some extent, physical bullying; Media literacy programs may mitigate the negative effects of electronic media on youth. Specific recommendations based on these conclusions are discussed, and research priorities for the prevention and education fields are identified. PMID:18047948

    Full Text Available Abstract Objective To assess government actions to improve the healthiness of food environments in New Zealand, based on the healthy food environment policy index. Methods A panel of 52 public health experts rated the extent of government implementation against international best practice for 42 indicators of food environment policy and infrastructure support. Their ratings were informed by documented evidence, validated by government officials and international benchmarks. Findings There was a high level of implementation for some indicators: providing ingredient lists and nutrient declarations and regulating health claims on packaged foods; transparency in policy development; monitoring prevalence of noncommunicable diseases and monitoring risk factors for noncommunicable diseases. There was very little, if any implementation of the following indicators: restrictions on unhealthy food marketing to children; fiscal and food retail policies and protection of national food environments within trade agreements. Interrater reliability was 0.78 (95% confidence interval, CI: 0.76-0.79. Based on the implementation gaps, the experts recommended 34 actions, and prioritized seven of these. Conclusion The healthy food environment policy index provides a useful set of indicators that can focus attention on where government action is needed. It is anticipated that this policy index will increase accountability of governments, stimulate government action and support civil society advocacy efforts.

  1. The Appropriateness of Renal Angioplasty. The ANPARIA Software: A Multidisciplinary Expert Panel Approach

    International Nuclear Information System (INIS)

    Percutaneous transluminal renal angioplasty (PTRA) is an invasive technique that is costly and involves the risk of complications and renal failure. The ability of PTRA to reduce the administration of antihypertensive drugs has been demonstrated. A potentially greater benefit, which nevertheless remains to be proven, is the deferral of the need for chronic dialysis. The aim of the study (ANPARIA) was to assess the appropriateness of PTRA to impact on the evolution of renal function. A standardized expert panel method was used to assess the appropriateness of medical treatment alone or medical treatment with revascularization in various clinical situations. The choice of revascularization by either PTRA or surgery was examined for each clinical situation. Analysis was based on a detailed literature review and on systematically elicited expert opinion, which were obtained during a two-round modified Delphi process. The study provides detailed responses on the appropriateness of PTRA for 1848 distinct clinical scenarios. Depending on the major clinical presentation, appropriateness of revascularization varied from 32% to 75% for individual scenarios (overal 48%). Uncertainty as to revascularization was 41% overall. When revascularization was appropriate, PTRA was favored over surgery in 94% of the scenarios, except in certain cases of aortic atheroma where sugery was the preferred choice. Kidney size >7 cm, absence of coexisting disease, acute renal failure, a high degree of stenosis (≥70%), and absence of multiple arteries were identified as predictive variables of favorable appropriateness ratings. Situations such as cardiac failure with pulmonary edema or acute thrombosis of the renal artery were defined as indications for PTRA. This study identified clinical situations in which PTRA or surgery are appropriate for renal artery disease. We built a decision tree which can be used via Internet: the ANPARIA software (http://www

    Oligonucleotides (ONs) are an emerging class of drugs being developed for the treatment of a wide variety of diseases including the treatment of respiratory diseases by the inhalation route. As a class, their toxicity on human lungs has not been fully characterized, and predictive toxicity biomarkers have not been identified. To that end, identification of sensitive methods and biomarkers that can detect toxicity in humans before any long term and/or irreversible side effects occur would be helpful. In light of the public's greater interests, the Inhalation Subcommittee of the Oligonucleotide Safety Working Group (OSWG) held expert panel discussions focusing on the potential toxicity of inhaled ONs and assessing the strengths and weaknesses of different monitoring techniques for use during the clinical evaluation of inhaled ON candidates. This white paper summarizes the key discussions and captures the panelists' perspectives and recommendations which, we propose, could be used as a framework to guide both industry and regulatory scientists in future clinical research to characterize and monitor the short and long term lung response to inhaled ONs.

    The National Toxicology Program (NTP) and the National Institute of Environmental Health Sciences (NIEHS) established the NTP Center for the Evaluation of Risks to Human Reproduction (CERHR) in June 1998. The purpose of CERHR is to provide timely, unbiased, scientifically sound evaluations of human and experimental evidence for adverse effects on reproduction and development caused by agents to which humans may be exposed. Hydroxyurea was selected for evaluation by a CERHR expert panel because of (1) its increasing use in the treatment of sickle cell disease in children and adults, (2) knowledge that it inhibits DNA synthesis and is cytotoxic, and (3) published evidence of its reproductive and developmental toxicity in rodents. Hydroxyurea is FDA-approved for reducing the frequency of painful crises and the need for blood transfusions in adults with sickle cell anemia who experience recurrent moderate-to-severe crises. Hydroxyurea is used in the treatment of cancer, sickle cell disease, and thalassemia. It is the only treatment for sickle cell disease aside from blood transfusion used in children. Hydroxyurea may be used in the treatment of children and adults with sickle cell disease for an extended period of time or for repeated cycles of therapy. Treatment with hydroxyurea may be associated with cytotoxic and myelosuppressive effects, and hydroxyurea is mutagenic.

    Prescription drug monitoring programs are generally underused in emergency departments (ED) and nationwide enrollment is low among emergency physicians. We aimed to develop consensus recommendations for prescription drug monitoring program policy and design to optimize their functionality and use in the ED. We assembled a technical expert panel with key stakeholders in emergency medicine, public health, and public policy. The panel included academic and community-based emergency physicians, a pediatric fellowship-trained emergency physician, a medical toxicologist, a public health expert, a patient advocate, a legal expert, and two state prescription drug monitoring program administrators. We compiled prescription drug monitoring program policies and characteristics and organized them into domains based on user-prescription drug monitoring program interaction. The panel convened for 3 rounds in which the policies and characteristics were introduced, discussed, and modified in an iterative fashion to achieve consensus. The process yielded policy recommendations and design features, with majority agreement. The panel made 18 policy recommendations within these main themes: enrollment should be mandatory, with an automatic process to mitigate the workload; registration should be open to all prescribers; delegates should have access to prescription drug monitoring program to alleviate work flow burdens; prescription drug monitoring program data should be pushed into hospital electronic health records; prescription drug monitoring program review should be mandatory for patients receiving opioid prescriptions and based on objective criteria; the prescription drug monitoring program content should be standardized and updated in a timely manner; and states should encourage interstate data sharing. An expert panel identified 18 recommendations that can be used by states and policymakers to improve prescription drug monitoring program design to increase use in the ED

    2009-01-01

    There are currently several physiological monitoring requirements for EVA in the Human-Systems Interface Requirements (HSIR) document. There are questions as to whether the capability to monitor heart rhythm in the lunar surface space suit is a necessary capability for lunar surface operations. Similarly, there are questions as to whether the capability to monitor heart rhythm during a cabin depressurization scenario in the launch/landing space suit is necessary. This presentation seeks to inform space medicine personnel of recommendations made by an expert panel of cardiovascular medicine specialists regarding in-suit ECG heart rhythm monitoring requirements during lunar surface operations. After a review of demographic information and clinical cases and panel discussion, the panel recommended that ECG monitoring capability as a clinical tool was not essential in the lunar space suit; ECG monitoring was not essential in the launch/landing space suit for contingency scenarios; the current hear rate monitoring capability requirement for both launch/landing and lunar space suits should be maintained; lunar vehicles should be required to have ECG monitoring capability with a minimum of 5-lead ECG for IVA medical assessments; and, exercise stress testing for astronaut selection and retention should be changed from the current 85% maximum heart rate limit to maximal, exhaustive 'symptom-limited' testing to maximize diagnostic utility as a screening tool for evaluating the functional capacity of astronauts and their cardiovascular health.

    Tuberculosis is a major cause of morbidity and mortality in women of childbearing age (15-44 years). Despite increased tuberculosis risk during pregnancy, optimal clinical treatment remains unclear: safety, tolerability, and pharmacokinetic data for many tuberculosis drugs are lacking, and trials of promising new tuberculosis drugs exclude pregnant women. To advance inclusion of pregnant and postpartum women in tuberculosis drug trials, the US National Institutes of Health convened an international expert panel. Discussions generated consensus statements (>75% agreement among panelists) identifying high-priority research areas during pregnancy, including: (1) preventing progression of latent tuberculosis infection, especially in women coinfected with human immunodeficiency virus; (2) evaluating new agents/regimens for treatment of multidrug-resistant tuberculosis; and (3) evaluating safety, tolerability and pharmacokinetics of tuberculosis drugs already in use during pregnancy and postpartum. Incorporating pregnant women into clinical trials would extend evidence-based tuberculosis prevention and treatment standards to this special population. PMID:26658057

    The present position paper summarises the outcomes of an expert panel discussion held by hospital-based and office-based physicians with ample experience in the treatment of geriatric patients. The optimal approach to stroke prevention in geriatric patients with atrial fibrillation (AF) has not been adequately clarified. Despite their high risk of stroke and clear indication for anticoagulation according to established risk scores, in practice geriatric AF patients often are withheld treatment because of comorbidities and comedications, concerns about low treatment adherence or fear of bleeding events, in particular due to falls. The panel agreed that geriatric patients should receive oral anticoagulation as a rule, unless a comprehensive neurological and geriatric assessment (including clinical examination, gait tests and validated instruments such as Modified Rankin Scale, Mini-mental state examination or Timed Test of Money Counting) provides sound reasons for refraining from treatment. All patients with a history of falls should be thoroughly evaluated for further evaluation of the causes. Patients with CHADS2 score ≥ 2 should receive anticoagulation even if at high risk for falls. The novel oral anticoagulants (NOAC) facilitate management in the geriatric population with AF (no INR monitoring needed, easier bridging during interventions) and have, based on available data, an improved benefit-risk ratio compared to vitamin K antagonists. Drugs with predominantly non-renal elimination are safer in geriatric patients and should be preferred. PMID:25285794

    Private wells serving fewer than 25 people are federally unregulated, and their users may be exposed to naturally occurring agents of concern such as arsenic and radionuclides, as well as anthropogenic contaminants. The Centers for Disease Control and Prevention's Clean Water for Health Program works to protect private wells and prevent adverse health outcomes for the roughly 15% of Americans who rely on them. To understand current and emerging challenges to the private drinking water supply, an interdisciplinary expert panel workshop on "Future and Emerging Issues for Private Wells" was organized to inform strategic planning for the Clean Water for Health Program. The panel assessed current conditions of ground water as a source for private wells, identified emerging threats, critical gaps in knowledge, and public health needs, and recommended strategies to guide future activities to ensure the safety of private drinking water wells. These strategies addressed topics of broad interest to the environmental public health community including: development of new methods to support citizen science; addressing contaminant mixtures; expanding capacity for well testing; evaluating treatment technologies; building an evidence base on best practices on well owner outreach and stewardship; and research and data needs.

    1984-11-01

    The Columbia River basalts underlying the Hanford Site in Washington State are being considered as a possible location for a geologic repository for high-level nuclear waste. To investigate the feasibility of a repository at this site, the hydrologic parameters of the site must be evaluated. Among hydrologic parameters of particular interest are the effective porosity of the Cohassett basalt flow top and flow interior and the vertical-to-horizontal hydraulic conductivity, or anisotropy ratio, of the Cohassett basalt flow interior. The Cohassett basalt flow is the prime candidate horizon for repository studies. Site-specific data for these hydrologic parameters are currently inadequate for the purpose of preliminary assessment of candidate repository performance. To obtain credible, auditable, and independently derived estimates of the specified hydrologic parameters, a panel of five nationally recognized hydrologists was assembled. Their expert judgments were quantified during two rounds of Delphi process by means of a probability encoding method developed to estimate the probability distributions of the selected hydrologic variables. The results indicate significant differences of expert opinion for cumulative probabilities of less than 10% and greater than 90%, but relatively close agreement in the middle ranges of values. The principal causes of the diversity of opinion are believed to be the lack of site-specific data and the absence of a single, widely accepted, conceptual or theoretical basis for analyzing these variables.

  2. Probability encoding of hydrologic parameters for basalt. Elicitation of expert opinions from a panel of five consulting hydrologists

    International Nuclear Information System (INIS)

    The Columbia River basalts underlying the Hanford Site in Washington State are being considered as a possible location for a geologic repository for high-level nuclear waste. To investigate the feasibility of a repository at this site, the hydrologic parameters of the site must be evaluated. Among hydrologic parameters of particular interest are the effective porosity of the Cohassett basalt flow top and flow interior and the vertical-to-horizontal hydraulic conductivity, or anisotropy ratio, of the Cohassett basalt flow interior. The Cohassett basalt flow is the prime candidate horizon for repository studies. Site-specific data for these hydrologic parameters are currently inadequate for the purpose of preliminary assessment of candidate repository performance. To obtain credible, auditable, and independently derived estimates of the specified hydrologic parameters, a panel of five nationally recognized hydrologists was assembled.

    Invasive Candida infections contribute to significant morbidity and mortality in patients with healthcare-associated infections. They represent a major burden on the public health system, and are challenging to diagnose and treat. A multidisciplinary expert panel critically reviewed available evidence to provide consensus recommendations for the management of invasive Candida infections in the Middle East. Based on diagnosis, recommendations were provided for the management of Candida infections in non-neutropenic and neutropenic patients. Polyenes (amphotericin B-deoxycholate [AmB-d] and lipid formulations amphotericin B [LFAmB]), triazoles (fluconazole, itraconazole and voriconazole), echinocandins (caspofungin, anidulafungin, and micafungin) and flucytosine are the recommended categories of antifungal agents for treatment of Candida infections. Echinocandins are preferred for treatment of proven and suspected Candida infections, especially in critically ill patients or those with previous exposure to azoles. Recommendations were also provided for infections caused by specific Candida species as well as management of different disease conditions. The experts highlighted that the guidelines should be used along with clinical judgment. Given the paucity of published data from the region, research in the form of randomized clinical trials should be given priority. PMID:24035607

    We summarize conclusions drawn from a panel discussion at the "Fifth International Congress on Vegetarian Nutrition" about the roles of and emphasis on food, plant food, and vegetarianism in current and future US dietary guidelines. The most general recommendation of the panel was that future dietary guidelines, following the lead of the 2005 Dietary Guidelines Advisory Committee, should emphasize food-based recommendations and thinking to the full extent that evidence allows. Although nutrient-based thinking and Dietary Reference Intakes (DRIs) may help ensure an adequate diet in the sense that deficiency states are avoided, the emphasis on DRIs may not capture many important nutritional issues and may inhibit a focus on foods. More generally, in the context of the conference on vegetarian nutrition, this report focuses on the history and structure of the Dietary Guidelines Advisory Committee, on various plant food-oriented recommendations that are supported by literature evidence, and on mechanisms for participating in the process of forming dietary guidelines. Among recommendations that likely would improve health and the environment, some are oriented toward increased plant food consumption and some toward vegetarianism. The literature on health effects of individual foods and whole lifestyle diets is insufficient and justifies a call for future food-oriented research, including expanding the evidence base for plant-based and vegetarian diets. The Dietary Guidelines Advisory Committee's role should be carried forward to creation of a publicly accessible icon (eg, the current pyramid) and related materials to ensure that the science base is fully translated for the public.

    Our scientific knowledge of bullous pemphigoid (BP) has dramatically progressed in recent years. However, despite the availability of various therapeutic options for the treatment of inflammatory diseases, only a few multicenter controlled trials have helped to define effective therapies in BP. A major obstacle in sharing multicenter-based evidences for therapeutic efforts is the lack of generally accepted definitions for the clinical evaluation of patients with BP. Common terms and end points of BP are needed so that experts in the field can accurately measure and assess disease extent, activity, severity, and therapeutic response, and thus facilitate and advance clinical trials. These recommendations from the International Pemphigoid Committee represent 2 years of collaborative efforts to attain mutually acceptable common definitions for BP and proposes a disease extent score, the BP Disease Area Index. These items should assist in the development of consistent reporting of outcomes in future BP reports and studies. PMID:22056920

    Trastuzumab has transformed the treatment of HER2-positive breast cancer. Because of impending European patent expiry in 2017, numerous trastuzumab biosimilars are currently undergoing comparability exercises for marketing authorization. Although biosimilar products have been approved in Europe since 2006, many obstacles are expected for trastuzumab, resulting from its nature as a monoclonal antibody, its impact on overall survival, and its extensive biochemical complexities. Unsolved questions need to be addressed for the evaluation of biosimilars' activity in terms of appropriate clinical endpoint definitions for such anticancer drugs, specific assessment pathways and comparative testing of biosimilars, untested ensuing de facto combination of trastuzumab biosimilars with cytotoxics, and immunogenicity monitoring among immunocompromised patients. In such a context of uncertainties, the recent approval by the French parliament of biosimilar substitution, which would allow dispensing trastuzumab biosimilars in place of the originator, should interrogate the oncological community. A think tank of experts was created to delineate specificities and challenges stemming from trastuzumab biosimilars. PMID:26352219

    2007-08-01

    In the process of developing a generic Hazard Analysis and Critical Control Point (HACCP)-like system for securing animal health and welfare in organic egg production, an expert panel analysis was used to perform the initial hazard analysis. Eighteen advisers and researchers in organic egg production were included in the expert panel. In a series of four questionnaires, the expert panel first scored 34 health and welfare problems seen in Danish organic egg production. Based on scorings of severity and occurrence, 10 problems were selected for further analysis. The experts subsequently suggested and scored risk factors for those problems and finally suggested control points, alarm values indicating the need for corrective actions in order to control the risk factors and monitoring frequencies of these. The 10 selected problems were hunger, thirst, piling, crop impaction, blackhead, pasteurellosis, bone fractures, cannibalism, predators and red mites. A total of 154 different risk factors were suggested for these problems. The 41 risk factors which rated highest in a combined scoring of importance and occurrence were selected for further analysis. There was a high degree of consensus between experts when scoring both problems and risk factors. The level of consensus, as defined by an interquartile range 1, was 79% to 100% when scoring the health and welfare problems (scale 1-5) and 77% to 95% when scoring the risk factors (scale 1-4). On average, 5.8 control points were suggested for every risk factor. Alarm values were often not detailed enough to be of practical significance and further analysis is needed in order to define these. The experts were highly diverse in their suggested monitoring frequencies and establishment of monitoring schemes should be part of developing the farm specific systems. An expert panel analysis based on questionnaires was a useful tool during the first steps of developing a HACCP plan, conducting a hazard analysis and suggesting control

    Superficial fungal infections affect 20-25% of people worldwide and can cause considerable morbidity, particularly if an inflammatory component is present. As superficial fungal infections can be diverse, the treatment should be tailored to the individual needs of the patient and several factors should be taken into account when deciding on the most appropriate treatment option. These include the type, location and surface area of the infection, patient age, degree of inflammation and underlying comorbidities. Although several meta-analyses have shown that there are no significant differences between the numerous available topical antifungal agents with regard to mycological cure, agents differ in their specific intrinsic properties, which can affect their clinical use. The addition of a corticosteroid to an antifungal agent at the initiation of treatment can attenuate the inflammatory symptoms of the infection and is thought to increase patient compliance, reduce the risk of bacterial superinfection and enhance the efficacy of the antifungal agent. However, incorrect use of antifungal-corticosteroid therapy may be associated with treatment failure and adverse effects. This review summarises available treatment options for superficial fungal infections and provides general treatment recommendations based on the consensus outcomes of an Expert Panel meeting on the topical treatment of superficial mycoses.

  9. Expert Panel Report 3 (EPR-3): Guidelines for the Diagnosis and Management of Asthma-Summary Report 2007.

    2007-11-01

    Highlights of the National Asthma Education and Prevention Program's Expert Panel Report 3 (EPR-3): Guidelines for the Diagnosis and Management of Asthma-Full Report 2007 are presented in this EPR-3 summary report. The updated guidelines emphasize the importance of asthma control. Asthma control is the degree to which the manifestations of asthma are minimized by therapeutic intervention and the goals of therapy are met. Because asthma is highly variable, the level of control must be monitored on a periodic basis to determine whether therapy should be maintained or adjusted (stepped up if necessary, stepped down if possible). On the other hand, asthma severity is the intrinsic intensity of the disease process, most easily and directly measured in a patient not receiving long-term control therapy. For managing asthma, the recommendation is to assess severity to initiate therapy and assess control to adjust therapy. Recommendations for managing asthma include an expanded section on childhood asthma with addition of an age group 5 to 11 years old (earlier guidelines combined this group with adults). The guidelines provide new recommendations on patient education in settings beyond the physician's office, and new advice for controlling environmental factors that can cause asthma symptoms. The concepts of current impairment (frequency and intensity of symptoms, low lung function, and limitations of daily activities) and future risk (likelihood of exacerbations, progressive loss of lung function, or adverse side effects from medications) support a new approach to assessing and monitoring the patient's level of asthma control through use of multiple measures. The guidelines stress that some patients can still be at high risk for frequent exacerbations even if they have few day-to-day effects of asthma.Moreover, EPR-3 confirms the importance of teaching patients skills to self-monitor and manage asthma and to use a written asthma action plan, which should include

  10. Thyroid cancer in children living near Chernobyl. Expert panel report on the consequences of the Chernobyl accident

    International Nuclear Information System (INIS)

    In January 1992, the Radiation Protection Research Action formed a panel of thyroid experts in order to evaluate the current situation concerning reported increased rates of thyroid cancer in children living in the neighbourhood of Chernobyl, where the reactor accident occurred on April 26 1986 and resulted in widespread radioactive contamination over large areas of Belarus, Russia, Ukraine. Studies of the Atom Bomb survivors in Japan have revealed that the incidence of leukemia starts to increase some five years after exposure. For Chernobyl accident health consequences are now becoming evident. Thyroid cancer has already been observed in children. Iodine 131 was seen to pose a specific hazard because it is taken up by the body and concentrated in the thyroid gland. At a dose of 5 Gy to the childhood thyroid about 4000 thyroid cancers per 100000 children exposed can be anticipated. An essential component of the verification of this observation is the study of the pathology of the lesions, which derived from four cell types: follicular cells, C cells, lymphoid cells and connective tumor cells. All distant metastases are lung metastases. Measures to be considered for the prevention of the development of thyroid cancer in a radiation-exposed population include correction of iodine deficiency by iodine prophylaxis and suppression of TSH. There are three methods of diagnosis: ultrasound imaging, thyroid scanning, fine needle aspiration performed by skilled personnel. For the therapy total or near-total thyroidectomy is regarded as the treatment of choice. Radioactive iodine can be used to treat lymph node and distant metastases which take up iodine after a total thyroidectomy. Thyroid hormone replacement should be carried out with TSH suppressive doses of L-Thyroxine. 45 refs., 1 annexe

    In 2008, CDC convened an expert panel to gather input on the use of geospatial science in surveillance, research and program activities focused on CDC's Healthy Communities Goal. The panel suggested six priorities: spatially enable and strengthen public health surveillance infrastructure; develop metrics for geospatial categorization of community health and health inequity; evaluate the feasibility and validity of standard metrics of community health and health inequities; support and develop GIScience and geospatial analysis; provide geospatial capacity building, training and education; and, engage non-traditional partners. Following the meeting, the strategies and action items suggested by the expert panel were reviewed by a CDC subcommittee to determine priorities relative to ongoing CDC geospatial activities, recognizing that many activities may need to occur either in parallel, or occur multiple times across phases. Phase A of the action items centers on developing leadership support. Phase B focuses on developing internal and external capacity in both physical (e.g., software and hardware) and intellectual infrastructure. Phase C of the action items plan concerns the development and integration of geospatial methods. In summary, the panel members provided critical input to the development of CDC's strategic thinking on integrating geospatial methods and research issues across program efforts in support of its Healthy Communities Goal.

    Tumour lysis syndrome (TLS) is a life-threatening oncological emergency characterized by metabolic abnormalities including hyperuricaemia, hyperphosphataemia, hyperkalaemia and hypocalcaemia. These metabolic complications predispose the cancer patient to clinical toxicities including renal insufficiency, cardiac arrhythmias, seizures, neurological complications and potentially sudden death. With the increased availability of newer therapeutic targeted agents, such as rasburicase (recombinant urate oxidase), there are no published guidelines on the risk classification of TLS for individual patients at risk of developing this syndrome. We convened an international TLS expert consensus panel to develop guidelines for a medical decision tree to assign low, intermediate and high risk to patients with cancer at risk for TLS. Risk factors included biological evidence of laboratory TLS (LTLS), proliferation, bulk and stage of malignant tumour and renal impairment and/or involvement at the time of TLS diagnosis. An international TLS consensus expert panel of paediatric and adult oncologists, experts in TLS pathophysiology and experts in TLS prophylaxis and management, developed a final model of low, intermediate and high risk TLS classification and associated TLS prophylaxis recommendations.

    2013-06-15

    In October 2011, the UN Committee on World Food Security (CFS) recommended a ''review of biofuels policies -- where applicable and if necessary -- according to balanced science-based assessments of the opportunities and challenges that they may represent for food security so that biofuels can be produced where it is socially, economically and environmentally feasible to do so''. In line with this, the CFS requested the HLPE (High Level Panel of Experts) to ''conduct a science-based comparative literature analysis taking into consideration the work produced by the FAO and Global Bioenergy Partnership (GBEP) of the positive and negative effects of biofuels on food security''. Recommendations from the report include the following. Food security policies and biofuel policies cannot be separated because they mutually interact. Food security and the right to food should be priority concerns in the design of any biofuel policy. Governments should adopt the principle: biofuels shall not compromise food security and therefore should be managed so that food access or the resources necessary for the production of food, principally land, biodiversity, water and labour are not put at risk. The CFS should undertake action to ensure that this principle is operable in the very varied contexts in which all countries find themselves. Given the trend to the emergence of a global biofuels market, and a context moving from policy-driven to market-driven biofuels, there is an urgent need for close and pro-active coordination of food security, biofuel/bioenergy policies and energy policies, at national and international levels, as well as rapid response mechanisms in case of crisis. There is also an urgent need to create an enabling, responsible climate for food and non-food investments compatible with food security. The HLPE recommends that governments adopt a coordinated food security and energy security strategy, which would require articulation

  5. Estimates of the solubilities of waste element radionuclides in waste isolation pilot plant brines: A report by the expert panel on the source term

    International Nuclear Information System (INIS)

    Evaluation of the long-term performance of the WIPP includes estimation of the cumulative releases of radionuclide elements to the accessible environment. Nonradioactive lead is added because of the large quantity expected in WIPP wastes. To estimate the solubilities of these elements in WIPP brines, the Panel used the following approach. Existing thermodynamic data were used to identify the most likely aqueous species in solution through the construction of aqueous speciation diagrams. Existing thermodynamic data and expert judgment were used to identify potential solubility-limiting solid phases. Thermodynamic data were used to calculate the activities of the radionuclide aqueous species in equilibrium with each solid. Activity coefficients of the radionuclide-bearing aqueous species were estimated using Pitzer's equations. These activity coefficients were then used to calculate the concentration of each radionuclide at the 0.1 and 0.9 fractiles. The 0.5 fractile was chosen to represent experimental data with activity coefficient corrections as described above. Expert judgment was used to develop the 0.0, 0.25, 0.75, and 1.0 fractiles by considering the sensitivity of solubility to the potential variability in the composition of brine and gas, and the extent of waste contaminants, and extending the probability distributions accordingly. The results were used in the 1991 and 1992 performance assessment calculations. 68 refs

    2016-02-01

    The probability and consequences of gene flow to wild relatives is typically considered in the environmental risk assessment of genetically engineered crops. This is a report from a discussion by a group of experts who used a problem formulation approach to consider existing information for risk assessment of gene flow from cassava (Manihot esculenta) genetically engineered for virus resistance to the 'wild' (naturalized) relative M. glaziovii in East Africa. Two environmental harms were considered in this case: (1) loss of genetic diversity in the germplasm pool, and (2) loss of valued species, ecosystem resources, or crop yield and quality due to weediness or invasiveness of wild relatives. Based on existing information, it was concluded that gene flow will occur, but it is not likely that this will reduce the genetic diversity in the germplasm pool. There is little existing information about the impact of the virus in natural populations that could be used to inform a prediction about whether virus resistance would lead to an increase in reproduction or survival, hence abundance of M. glaziovii. However, an increase in the abundance of M. glaziovii should be manageable, and would not necessarily lead to the identified environmental harms. PMID:26667472

The purpose of this expert panel review was to examine currently available literature on the potential role of biomarkers to improve antimicrobial prescribing, by answering three questions: 1) Which are the biomarkers available for this purpose?; 2) What is their potential role in the initiation of antibiotic therapy?; and 3) What is their role in the decision to stop antibiotic therapy? To answer these questions, studies reviewed were limited to recent clinical studies (50) and restricted to controlled trials and meta-analyses for answering questions 2 and 3. With regard to the first question concerning routinely available biomarkers, which might be useful for antibiotic management of acute infections, these are currently limited to C-reactive protein (CRP) and procalcitonin (PCT). Other promising biomarkers that may prove useful in the near future but need to undergo more extensive clinical testing include sTREM-1, suPAR, ProADM, and Presepsin. New approaches to biomarkers of infections include point-of-care testing and genomics. PMID:23837559

    Despite the fact that seizures are commonly associated with autism spectrum disorder (ASD), the effectiveness of treatments for seizures has not been well studied in individuals with ASD. This manuscript reviews both traditional and novel treatments for seizures associated with ASD. Studies were selected by systematically searching major electronic databases and by a panel of experts that treat ASD individuals. Only a few anti-epileptic drugs (AEDs) have undergone carefully controlled trials in ASD, but these trials examined outcomes other than seizures. Several lines of evidence point to valproate, lamotrigine, and levetiracetam as the most effective and tolerable AEDs for individuals with ASD. Limited evidence supports the use of traditional non-AED treatments, such as the ketogenic and modified Atkins diet, multiple subpial transections, immunomodulation, and neurofeedback treatments. Although specific treatments may be more appropriate for specific genetic and metabolic syndromes associated with ASD and seizures, there are few studies which have documented the effectiveness of treatments for seizures for specific syndromes. Limited evidence supports l-carnitine, multivitamins, and N-acetyl-l-cysteine in mitochondrial disease and dysfunction, folinic acid in cerebral folate abnormalities and early treatment with vigabatrin in tuberous sclerosis complex. Finally, there is limited evidence for a number of novel treatments, particularly magnesium with pyridoxine, omega-3 fatty acids, the gluten-free casein-free diet, and low-frequency repetitive transcranial magnetic simulation. Zinc and l-carnosine are potential novel treatments supported by basic research but not clinical studies. This review demonstrates the wide variety of treatments used to treat seizures in individuals with ASD as well as the striking lack of clinical trials performed to support the use of these treatments. Additional studies concerning these treatments for controlling seizures in individuals

    International Nuclear Information System (INIS)

    The present study implemented a probability encoding method to estimate the probability distributions of selected hydrologic variables for the Cohassett basalt flow top and flow interior, and the anisotropy ratio of the interior of the Cohassett basalt flow beneath the Hanford Site. Site-speciic data for these hydrologic parameters are currently inadequate for the purpose of preliminary assessment of candidate repository performance. However, this information is required to complete preliminary performance assessment studies. Rockwell chose a probability encoding method developed by SRI International to generate credible and auditable estimates of the probability distributions of effective porosity and hydraulic conductivity anisotropy. The results indicate significant differences of opinion among the experts. This was especially true of the values of the effective porosity of the Cohassett basalt flow interior for which estimates differ by more than five orders of magnitude. The experts are in greater agreement about the values of effective porosity of the Cohassett basalt flow top; their estimates for this variable are generally within one to two orders of magnitiude of each other. For anisotropy ratio, the expert estimates are generally within two or three orders of magnitude of each other. Based on this study, the Rockwell hydrologists estimate the effective porosity of the Cohassett basalt flow top to be generally higher than do the independent experts. For the effective porosity of the Cohassett basalt flow top, the estimates of the Rockwell hydrologists indicate a smaller uncertainty than do the estimates of the independent experts. On the other hand, for the effective porosity and anisotropy ratio of the Cohassett basalt flow interior, the estimates of the Rockwell hydrologists indicate a larger uncertainty than do the estimates of the independent experts

    In May 2004, 12 experts in evaluating large-scale health communication programs came to the Centers for Disease Control and Prevention to participate in an electronic focus group discussion. They offered advice on topics ranging from the role of logic models to the best strategies for controlling for self-selection bias in surveys regarding outcomes of exposure to mass media health messages. The experts also highlighted health communication evaluation topics that have received too little scientific attention. Finally, they made strategic policy recommendations. Use of the state-of-the-art evaluation methods that they recommended could improve the communication of factual and persuasive health messages and help to guard the public health of the nation. Their advice may also advance evaluation practice in other substantive areas, especially where it is difficult or impossible to implement randomized designs. PMID:17693617

    Skin reactions due to radiotherapy and chemotherapy are a significant problem for an important number of cancer patients. While effective for treating cancer, they disturb cutaneous barrier function, causing a reaction soon after initiation of treatment that impacts patient quality of life. Managing these symptoms with cosmetics and nonpharmaceutical skin care products for camouflage or personal hygiene may be important for increasing patient self-esteem. However, inappropriate product choice or use could worsen side effects. Although recommendations exist for the pharmaceutical treatment of skin reactions, there are no recommendations for the choice or use of dermatologic skin care products for oncology patients. The present guidelines were developed by a board of European experts in dermatology and oncology to provide cancer care professionals with guidance for the appropriate use of non-pharmaceutical, dermocosmetic skin care management of cutaneous toxicities associated with radiotherapy and systemic chemotherapy, including epidermal growth factor inhibitors and monoclonal antibodies. The experts hope that these recommendations will improve the management of cutaneous side effects and hence quality of life for oncology patients. PMID:24353440

    Stemming from breast density notification legislation in Massachusetts effective 2015, we sought to develop a collaborative evidence-based approach to density notification that could be used by practitioners across the state. Our goal was to develop an evidence-based consensus management algorithm to help patients and health care providers follow best practices to implement a coordinated, evidence-based, cost-effective, sustainable practice and to standardize care in recommendations for supplemental screening. We formed the Massachusetts Breast Risk Education and Assessment Task Force (MA-BREAST) a multi-institutional, multi-disciplinary panel of expert radiologists, surgeons, primary care physicians, and oncologists to develop a collaborative approach to density notification legislation. Using evidence-based data from the Institute for Clinical and Economic Review, the Cochrane review, National Comprehensive Cancer Network guidelines, American Cancer Society recommendations, and American College of Radiology appropriateness criteria, the group collaboratively developed an evidence-based best-practices algorithm. The expert consensus algorithm uses breast density as one element in the risk stratification to determine the need for supplemental screening. Women with dense breasts and otherwise low risk (20% lifetime) should consider supplemental screening MRI in addition to routine mammography regardless of breast density. We report the development of the multi-disciplinary collaborative approach to density notification. We propose a risk stratification algorithm to assess personal level of risk to determine the need for supplemental screening for an individual woman. PMID:26290416

  17. Guest Editorial: Pressure ulcer management and research priorities for patients with spinal cord injury: Consensus opinion from SCI QUERI Expert Panel on Pressure Ulcer Research Implementation

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Pressure ulcers (PUs are a serious and costly complication for many individuals with reduced mobility and sensation. Some populations, such as those with spinal cord injury and disease (SCI/D, remain at high risk throughout their lifetimes. Clinical observations and research have demonstrated staggering costs and human suffering because of PUs, including profound negative effect on general physical health, socialization, financial status, body image, and level of independence and control [1-2]. The International Pressure Ulcer Prevalence Study from 2006 to 2009 demonstrated a change in PU prevalence in the U.S. healthcare facility population. Overall, PU prevalence was slightly lower in 2009 than in 2006, but prevalence of suspected deep-tissue injuries (DTIs increased during the same period [3]. Further investigation into the cause of these changes is warranted. DTI diagnosis frequency may have been affected by the addition of suspected DTI to the revised National Pressure Ulcer Advisory Panel (NPUAP staging definitions in 2007 and rule changes for Centers for Medicare and Medicaid reimbursement.

    Abstract For genetic research to contribute more fully to furthering our knowledge of neuropathic pain, we require an agreed, valid, and feasible approach to phenotyping, to allow collaboration and replication in samples of sufficient size. Results from genetic studies on neuropathic pain have been inconsistent and have met with replication difficulties, in part because of differences in phenotypes used for case ascertainment. Because there is no consensus on the nature of these phenotypes, nor on the methods of collecting them, this study aimed to provide guidelines on collecting and reporting phenotypes in cases and controls for genetic studies. Consensus was achieved through a staged approach: (1) systematic literature review to identify all neuropathic pain phenotypes used in previous genetic studies; (2) Delphi survey to identify the most useful neuropathic pain phenotypes and their validity and feasibility; and (3) meeting of experts to reach consensus on the optimal phenotype(s) to be collected from patients with neuropathic pain for genetic studies. A basic “entry level” set of phenotypes was identified for any genetic study of neuropathic pain. This set identifies cases of “possible” neuropathic pain, and controls, and includes: (1) a validated symptom-based questionnaire to determine whether any pain is likely to be neuropathic; (2) body chart or checklist to identify whether the area of pain distribution is neuroanatomically logical; and (3) details of pain history (intensity, duration, any formal diagnosis). This NeuroPPIC “entry level” set of phenotypes can be expanded by more extensive and specific measures, as determined by scientific requirements and resource availability. PMID:26469320

    FDG PET/CT is able to detect active disease in patients with multiple myeloma (MM) and can be helpful for staging and assessing therapy response, but no standard interpretation criteria have been proposed for the evaluation of FDG PET/CT in MM. A group of Italian nuclear medicine physicians and haematologists met to propose new visual interpretation criteria to standardize FDG PET/CT evaluation in MM patients (Italian Myeloma criteria for PET USe; IMPeTUs) and the reproducibility of these criteria was tested. This Italian multicentre protocol was set up as a subprotocol of EMN02, an international prospective multicentre trial of the European Myeloma Network. The criteria were agreed at multidisciplinary consensus meetings. They include a description of the metabolic state of the bone marrow (BM), number and site of focal PET-positive lesions, the number of osteolytic lesions, and the presence and site of extramedullary disease, paramedullary disease and fractures. A visual degree of uptake was defined for the target lesion and extramedullary lesions according to modified Deauville criteria. MM patients who had undergone FDG PET/CT at baseline (PET-0), after induction (PET-AI) and at the end of treatment (PET-EoT) were enrolled. The patients had been prospectively enrolled in EMN02 and their PET scans were a posteriori reinterpreted in a blinded independent central review process managed by WIDEN registered. Five expert nuclear medicine physicians scored the scans according to the new criteria. A case was considered read when four out of the five reviewers completed the report. Concordance among reviewers on different metrics was calculated using Krippendorff's alpha coefficient. A total of 17 consecutive patients were enrolled. On PET-0, the alpha coefficients for the BM score, the score for the hottest focal lesion, the number of focal lesions and the number of lytic lesions were 0.33 and 0.47, 0.40 and 0.32, respectively. On PET-AI, the alpha coefficients

    Lung cancer is the leading cause of death from cancer worldwide that currently has only a few available treatment options in patients with no driver mutations. The therapeutic options for patients with non-small-cell lung cancer (NSCLC) who progress after first-line chemotherapy have been limited from a long time. Docetaxel has remained a cornerstone of second-line treatment for more than 20 years, but it is associated with an unfavorable safety profile. Recently, the results from immunotherapy treatment with anti-PD1 and PD-L1 inhibitors has changed our current knowledge base and increased therapeutic options for patients with NSCLC in the second-line setting. The results of 2 randomized phase III trials assessing nivolumab in lung cancer, Check-Mate-017 and Check-Mate-057, have deeply changed our current clinical practice and raised several discussion points. This paper explores the recent findings about nivolumab for the treatment of NSCLC in the second-line setting by analyzing recent trial findings and discussing their implications in clinical practice and future directions. The paper also summarizes the conclusions from an International Experts Panel Meeting of the Italian Association of Thoracic Oncology. PMID:26908078

  4. Expert knowledge, organisation and procedures of experts commissions, as the basis of authenticity of expert opinions

    International Nuclear Information System (INIS)

    The fact that codes of scientific and technical practice are often referred to as expertises on the state of technology, in particular by authorities and by the courts, leads to legal requirements on the competence of experts, organization and procedures of the panels. These requirements cannot be established without consideration of the various circumstances in different panels preparing regulations. Yet the conception of expertises allows conclusions as to the principles of the most essential topics. Compliance with these requirements may increase the authentication of statements made by panels of experts and, possibly, the authorities and courts will content themselves with controlling the procedure in the appraisal of the statements of such panels.

    In 1996, article 4590i of the Texas Revised Civil Statutes Annotated, the statutory provision that governs health care liability claims in Texas, was amended to require claimants to file expert reports within 180 days as part of the prosecution of their claims. Sufficient expert reports include explanations of the standard of care, the deviation from that standard, and how the deviation caused the claimant's damages. Two provisions allow courts to grant a 30-day extension for filing expert reports. A good cause extension can be used to extend the filing deadline to 210 days; however, case law has not clearly defined what constitutes good cause. An accident or mistake grace period can be used to justify reports filed >210 days after the suit has been filed; judges determine whether the failure is due to a mistake or intentional indifference. As with any statute, the language is not as important as how the courts (judges) interpret that language. The statute may appear strict but room for interpretation exists. PMID:16389359

The procedures, called "Expert Games", look outwardly as well-known computer "playthings" and at the same time are strong means for Knowledge Acquisition. If Expert wants to succeed, he must to use his professional knowledge. After analyzing game operations of an Expert it is possible to resolve reverse problem - to define which what kind of knowledge have been used for making Expert's decision during the game.

  13. Speech spectrogram expert

    Energy Technology Data Exchange (ETDEWEB)

    Johannsen, J.; Macallister, J.; Michalek, T.; Ross, S.

    1983-01-01

    Various authors have pointed out that humans can become quite adept at deriving phonetic transcriptions from speech spectrograms (as good as 90percent accuracy at the phoneme level). The authors describe an expert system which attempts to simulate this performance. The speech spectrogram expert (spex) is actually a society made up of three experts: a 2-dimensional vision expert, an acoustic-phonetic expert, and a phonetics expert. The visual reasoning expert finds important visual features of the spectrogram. The acoustic-phonetic expert reasons about how visual features relates to phonemes, and about how phonemes change visually in different contexts. The phonetics expert reasons about allowable phoneme sequences and transformations, and deduces an english spelling for phoneme strings. The speech spectrogram expert is highly interactive, allowing users to investigate hypotheses and edit rules. 10 references.

  14. Atomic liability panel

    International Nuclear Information System (INIS)

    It is generally recognized that the lack of adequate rules and accepted definitions of liability in the case of nuclear accidents constitutes a serious drawback to the growth of the atomic energy industry. This applies both t o national undertakings and, more particularly, to bilateral or international operations such as those carried out under the auspices of IAEA. The problems will grow even more complicated if countries adopt differing standards. The initial programme of IAEA therefore stresses the need for the establishment of international standards and definitions of areas of responsibility which would do much to harmonize national practices now being formulated in many countries. In order to initiate studies of this problem, the Director General has decided t o call a number of experts, representing various legal systems, together, and entrust them with the task of examining this question. He has appointed Ambassador Paul Ruegger (Switzerland) as Chairman of the panel

  2. Being an expert

    International Nuclear Information System (INIS)

    This series of short articles are dedicated to the role of the expert in the enterprise. There is an important difference between a scientific counsellor and an expert, the expert, recognized by his peers, can speak publicly in his field of expertise but has a duty of transparency while the job of a scientific counsellor requires confidentiality. The making and the use of an expert in an enterprise requires a dedicated organization. The organization of the expertise in 5 enterprises in nuclear industry are considered: CEA (French Alternative Energies and Atomic Energy Commission), IRSN (Institute of Radioprotection and Nuclear Safety), AREVA, ANDRA (National Radioactive Waste Management Agency) and EDF (Electricity of France)

  6. The Remarkable Staying Power of "Death Panels".

    Science.gov (United States)

    Frankford, David M

    2015-10-01

    Sarah Palin's phrase "death panels" derailed proposed provisions of the Affordable Care Act (ACA) to pay physicians for end-of-life discussions with patients, a policy designed to make dying more humane, something all Americans desire. Even now, "death panels" has truth-value for approximately half of Americans and is used to paint ACA components as threatening to "pull the plug on Grandma." How can this be? To some, the death panels claim is simply a lie, an improvised explosive device hurled against any ACA provision. To others, the phrase's power stems from the public's lack of a common vocabulary to discuss end-of-life care. "Death panels," however, taps into many Americans' fear of government involvement, that government's purchasing end-of-life discussions as commodities necessitates accountability and cost control. Standardization and reduction of humanity follows, something Americans already experience routinely in their health care system. Expert jargon, compelling among experts themselves, doesn't evoke people's images of chats with Marcus Welby. The jargon is unintelligible, off-putting. When that jargon enters the nonjargonized world, it mixes with common fears, extant experience of dehumanization and reduction, and awareness that someone's plug is getting pulled all the time. "Death panels" cannot be dismissed as delusional, but neither can it help fulfill Americans' aspirations for a humane last voyage. PMID:26195604

  14. Seismic hazard analysis. Review panel, ground motion panel, and feedback results

    International Nuclear Information System (INIS)

    The Site Specific Spectra Project (SSSP) was a multi-year study funded by the U.S. Nuclear Regulatory Commission to provide estimates of the seismic hazards at a number of nuclear power plant sites in the Eastern U.S. A key element of our approach was the Peer Review Panel, which we formed in order to ensure that our use of expert opinion was reasonable. We discuss the Peer Review Panel results and provide the complete text of each member's report. In order to improve the ground motion model, an Eastern U.S. Ground Motion Model Panel was formed. In Section 4 we tabulate the responses from the panel members to our feedback questionnaire and discuss the implications of changes introduced by them. We conclude that the net difference in seismic hazard values from those presented in Volume 4 is small and does not warrant a reanalysis. (author)

  18. A new way to ask the experts: Rating radioactive waste risks

    Energy Technology Data Exchange (ETDEWEB)

    Kerr, R.A.

    1996-11-08

    The possible risks of a proposed nuclear waste repository at Yucca Mountain include the dozen or more young volcanos near by. Now some earth scientists have a new approach to evaluating hazards accounting for uncertainty at every step - `expert elicitation.` This pulls together a panel of experts, carefully assesses the uncertainties of each of their views then mathematically combines their risk estimates along with the accompanying uncertainties. The article goes on to describe just such a panel which considered seismic hazards to Yucca Mountain, how they came to their conclusions, the arguments about the conclusions, and the future of expert elicitation in evaluating the risks of nuclear waste disposal.

    In the summer of 2013 the International Committee on Future Accelerators (ICFA) established a Neutrino Panel with the mandate: "To promote international cooperation in the development of the accelerator-based neutrino-oscillation program and to promote international collaboration in the development of a neutrino factory as a future intense source of neutrinos for particle physics experiments." In its first year the Panel organised a series of regional Town Meetings to collect input from the community and to receive reports from the regional planning exercises. The Panel distilled its findings and presented them in a report to ICFA [1]. In this contribution the formation and composition of the Panel are presented together with a summary of the Panel's findings from the three Regional Town Meetings. The Panel's initial conclusions are then articulated and the steps that the Panel seeks to take are outlined.

  3. Paneling architectural freeform surfaces

    KAUST Repository

    Eigensatz, Michael

    2010-07-26

    The emergence of large-scale freeform shapes in architecture poses big challenges to the fabrication of such structures. A key problem is the approximation of the design surface by a union of patches, socalled panels, that can be manufactured with a selected technology at reasonable cost, while meeting the design intent and achieving the desired aesthetic quality of panel layout and surface smoothness. The production of curved panels is mostly based on molds. Since the cost of mold fabrication often dominates the panel cost, there is strong incentive to use the same mold for multiple panels. We cast the major practical requirements for architectural surface paneling, including mold reuse, into a global optimization framework that interleaves discrete and continuous optimization steps to minimize production cost while meeting user-specified quality constraints. The search space for optimization is mainly generated through controlled deviation from the design surface and tolerances on positional and normal continuity between neighboring panels. A novel 6-dimensional metric space allows us to quickly compute approximate inter-panel distances, which dramatically improves the performance of the optimization and enables the handling of complex arrangements with thousands of panels. The practical relevance of our system is demonstrated by paneling solutions for real, cutting-edge architectural freeform design projects. © 2010 ACM.

  6. Bioethics for Technical Experts

    Science.gov (United States)

    Asano, Shigetaka

    Along with rapidly expanding applications of life science and technology, technical experts have been implicated more and more often with ethical, social, and legal problems than before. It should be noted that in this background there are scientific and social uncertainty elements which are inevitable during the progress of life science in addition to the historically-established social unreliability to scientists and engineers. In order to solve these problems, therefore, we should establish the social governance with ‘relief’ and ‘reliance’ which enables for both citizens and engineers to share the awareness of the issues, to design social orders and criterions based on hypothetical sense of values for bioethics, to carry out practical use management of each subject carefully, and to improve the sense of values from hypothetical to universal. Concerning these measures, the technical experts can learn many things from the present performance in the medical field.

    2013-04-01

    Almost every organization has people it can't do without--specialists with "deep smarts," who are the go-to experts on critical issues. But because their knowledge is experienced-based, it's often instinctive and unarticulated, and never gets passed on. Capturing it is a challenge for both the organization and for colleagues who wish to become in-house authorities themselves. This article offers a methodical system for acquiring deep smarts from an expert. It involves observing that person extensively to understand what makes him successful, practicing the behaviors he exhibits on your own, partnering with him to solve problems, and ultimately taking responsibility for some of his tasks. Describing the experiences of one executive as she takes this journey with a mentor, the authors show how you too can gain the wisdom that will make you indispensable to your firm. PMID:23593772

    Ionita, C

    2014-01-01

    The ALICE experiment at CERN employs a number of human operators (shifters), who have to make sure that the experiment is always in a state compatible with taking Physics data. Given the complexity of the system and the myriad of errors that can arise, this is not always a trivial task. The aim of this paper is to describe an expert system that is capable of assisting human shifters in the ALICE control room. The system diagnoses potential issues and attempts to make smart recommendations for troubleshooting. At its core, a Prolog engine infers whether a Physics or a technical run can be started based on the current state of the underlying sub-systems. A separate C++ component queries certain SMI objects and stores their state as facts in a Prolog knowledge base. By mining the data stored in dierent system logs, the expert system can also diagnose errors arising during a run. Currently the system is used by the on-call experts for faster response times, but we expect it to be adopted as a standard tool by reg...

    Richards, W. L.; Thompson, Randolph C.

    The paper describes the procedures of thermal mechanical tests carried out at the NASA Dryden Flight Research Facility on two tianium honeycomb wing panels bonded using liquid interface diffusion (LID) technique, and presents the results of these tests. The 58.4 cm square panels consisted of two 0.152-cm-thick Ti 6-2-4-2 face sheets LID-bonded to a 1.9-cm-thick honeycomb core, with bearing plates fastened to the perimeter of the upper and the lower panel surfaces. The panels were instrumented with sensors for measuring surface temperature, strain, and deflections to 315 C and 482 C. Thermal stress levels representative of those encountered during aerodynamic heating were produced by heating the upper panel surface and restraining all four edges. After more than 100 thermal cycles from room temperature to 315 C and 50 cycles from room temperature to 482 C, no significant structural degradation was detected in the panels.

    2015-10-01

    Full Text Available In various applications it is necessary to analyze some expert orderings, ie clustered rankings of examination objects. These areas include technical studies, ecology, management, economics, sociology, forecasting, etc. The objects may make samples of the products, technologies, mathematical models, projects, job applicants and others. We obtain clustered rankings which can be both with the help of experts and objective way, for example, by comparing the mathematical models with experimental data using a particular quality criterion. The method described in this article was developed in connection with the problems of chemical safety and environmental security of the biosphere. We propose a new method for constructing a clustered ranking which can be average (in the sense, discussed in this work for all clustered rankings under our consideration. Then the contradictions between the individual initial rankings are contained within clusters average (coordinated ranking. As a result, ordered clusters reflects the general opinion of the experts, more precisely, the total that is contained simultaneously in all the original rankings. Newly built clustered ranking is often called the matching (coordinated ranking with respect to the original clustered rankings. The clusters are enclosed objects about which some of the initial rankings are contradictory. For these objects is necessary to conduct the new studies. These studies can be formal mathematics (calculation of the Kemeny median, orderings by means of the averages and medians of ranks, etc. or these studies require involvement of new information from the relevant application area, it may be necessary conduct additional scientific research. In this article we introduce the necessary concepts and we formulate the new algorithm of construct the coordinated ranking for some cluster rankings in general terms, and its properties are discussed

    Throughout history, advances in technology have come in spurts. A single great idea can often spur rapid change as the idea takes hold and is propagated, often in totally unexpected directions. Exadata embodies such a change in how we think about and manage relational databases. The key change lies in the concept of offloading SQL processing to the storage layer. That concept is a huge win, and its implementation in the form of Exadata is truly a game changer. Expert Oracle Exadata will give you a look under the covers at how the combination of hardware and software that comprise Exadata actua

    In theory, the risk management groups of two British banks--Saxon and Anglo--had the same influence in their organizations. But in practice, they did not: Saxon's was engaged in critical work throughout the bank, while Anglo's had little visibility outside its areas of expertise. In their study of these two financial institutions, the authors identified four competencies--trailblazing, toolmaking, teamwork, and translation--that help functional leaders or groups compete for top management's limited attention and increase their impact. Anglo's risk managers were strong in only some of the competencies, but Saxon's were strong in all four. They consistently scanned the internal and external environment for important issues to which they could apply a risk management perspective (trailblazing) and then developed tools--such as quarterly risk reports--that spread their expertise (toolmaking). While controlling the tools' design and implementation, the risk managers incorporated business managers' insights (teamwork) and made sure everyone could understand the findings (translation). Ultimately, experts' roles must fit the organization's strategy and structural needs. In some situations, functional experts can raise their profile by cultivating just two of the competencies. But those who are strong in all four are likely to be the most influential. PMID:24730171

    Bush, Susan

    About 80 citizens concerned with the threat of ozone depletion attended a public meeting on June 9 in Charlottesville, Va., to discuss the issue with a panel of six leading ozone experts. Held in conjunction with the Quadrennial Ozone Symposium, the town meeting was videotaped for airing on public broadcast stations this fall. The meeting was aimed at nonexperts, to “get the word out” to the public, said the moderator, journalist Peter Hackes.The lively, sometimes heated discussion showed the public's high awareness and concern over problems associated with ozone depletion. During the nearly 2-hour meeting topics ranged from the reparability of the ozone layer, to steps the public can take to help mitigate ozone loss, to reports of increased cases of skin cancer due to more ultraviolet radiation reaching the Earth's surface. There were also some claims that ozone depletion is overexaggerated and is a hoax for scientists to get more research funding.

  6. Strategic environmental assessment quality assurance: evaluating and improving the consistency of judgments in assessment panels

    International Nuclear Information System (INIS)

    Assessment panels and expert judgment are playing increasing roles in the practice of strategic environmental assessment (SEA). Thus, the quality of an SEA decision rests considerably on the quality of the judgments of the assessment panel. However, there exists very little guidance in the SEA literature for practitioners concerning the treatment and integration of expert judgment into SEA decision-making processes. Subsequently, the performance of SEAs based on expert judgment is often less than satisfactory, and quality improvements are required in the SEA process. Based on the lessons learned from strategic- and project-level impact assessment practices, this paper outlines a number of principles concerning the use of assessment panels in SEA decision-making, and attempts to provide some guidance for SEA practitioners in this regard. Particular attention is given to the notion and value of consistency in assessment panel judgments

  7. Let the Experts Decide?

    We examine abstention when voters in standing committees are asymmetrically informed and there are multiple pure strategy equilibria-swing voter's curse (SVC) equilibria where voters with low quality information abstain and equilibria when all participants vote their information. When the asymmetry...... in information quality is large, we find that voting groups largely coordinate on the SVC equilibrium which is also Pareto Optimal. However, we find that when the asymmetry in information quality is not large and the Pareto Optimal equilibrium is for all to participate, significant numbers of voters...... with low quality information abstain. Furthermore, we find that information asymmetry induces voters with low quality information to coordinate on a non-equilibrium outcome. This suggests that coordination on "letting the experts" decide is a likely voting norm that sometimes validates SVC equilibrium...

  8. Expert system rheometry

    2009-09-01

    Full Text Available Inks, drilling fluids, shower gels and drug delivery vehicles are just a few examples of the many industrial and consumer products based on colloidal and nanostructured complex fluids. The successful formulation of these materials is promoted by understanding how rheological behaviour, which typically dictates performance, relates to underlying microstructure. However, this knowledge can be difficult to obtain for those without the necessary expertise. This article shows how recent developments in rheometer technology address this issue. New rheometers, exemplified by the Kinexus from Malvern have expert knowledge embedded within the instrument and are able to guide users through measurement and data analysis to relevant information. Such systems facilitate development of the design rules to optimize formulations and generate novel and high performance materials of the future.

  9. Expert system driven software

    International Nuclear Information System (INIS)

    Using large finite element analysis codes for heat transfer computations and for stresses and displacements under thermal loads computations are not always very simple because of the complexity of the problems and the number of domains involved. Often faulty results from computations are being used until an expert discovers that something was wrong in the simulation. As a result of recent advances in artificial intelligence techniques, solutions to these problems are now possible by making use of knowledge based systems in which expertise in several domains can easily be introduced. In this paper, we present an application of knowledge based systems for a finite element analysis code in heat transfer. The system is fairly general, and we think that application to any well structured numerical code should be straightforward. (orig.)

  10. Expert system in PNC, 5

    International Nuclear Information System (INIS)

    The computer code system which can evaluate the mass balance and cycle cost in nuclear fuel cycle has been developing a PNC using an artificial intelligence technique. This system is composed of the expert system, data base and analysis codes. The expert system is the most important one in the system and the content of the expert system is explained in this paper. The expert system has the three functions. The first is the function of understanding the meaning of user's questions by natural language, the second is the function of selecting the best way to solve the problem given by the user using the knowledge which is already installed in the system, and the last is the function of answering the questions. The knowledge of the experts installed in the expert system is represented by the frame-type rules. Therefore, the knowledge will be simply added to the system, and consequently the system will be easily extended. (author)

    Background Although there are various international consensus recommendations on the use of botulinum neurotoxin type A (BoNT/A) in facial aesthetics, there are no global or Russian guidelines on the optimal dose of incobotulinumtoxinA, free from complexing proteins, within specific aesthetic indications. This article reports the outcomes of two expert consensus meetings, conducted to review and analyze efficacy and tolerability data for incobotulinumtoxinA in various facial aesthetic indications and to give expert consensus recommendations to ensure best clinical practice among Russian clinicians. Methods Thirteen dermatology and/or plastic surgery experts attended meetings held in Paris, France (November 2013), and Moscow, Russia (March 2014). The expert group reviewed and analyzed the existing evidence, consensus recommendations, and Russian experts’ extensive practical experience of incobotulinumtoxinA in aesthetics to reach consensus on optimal doses, potential dose adjustments, and injection sites of incobotulinumtoxinA for facial aesthetics. Results All experts developed guidance on the optimal doses for incobotulinumtoxinA treatment of different regions of the upper and lower face. The expert panel agreed that there are no differences in the efficacy and duration of the effect between the four BoNT/As that are commercially available for facial aesthetic indications in Russia and that, when administered correctly, all BoNT/As can achieve optimal results. Experts also agreed that nonresponse to BoNT/A can be caused by neutralizing antibodies. Conclusion On the basis of the scientific and clinical evidence available for incobotulinumtoxinA, coupled with the extensive clinical experience of the consensus group, experts recommended the optimal doses of incobotulinumtoxinA effective for treatment of wrinkles of the upper and lower face to achieve the expected aesthetic outcome. These first Russian guidelines on the optimal use of incobotulinumtoxinA for

    1987-10-01

    In this paper we discuss how to generate the command value for the optimal regulator in an automotive antiskid system. First, the behavior of the vehicle at braking is expressed as a mathematical model with the formulation by physical consideration and identification of the hydraulic system by statistical methods. An optimal regulator with additional integral is applied to the automotive antiskid control in order to make the each wheel speed follow any command value. However, the desired command value to stop the vehicle efficiently and stably is dependent on ambiguous road surface conditions. Thus, how to determine the desired command value under the moment-to-moment conditions is most important. A method for inferring the conditions is developed using fuzzy logic, with three fuzzy variables expressing the conditions adequately. On the basis of the inference, the ideal command values are generated. Outstanding control performance and good adaptability are obtained in vehicle experiments. Consequently, the Expert Antiskid System, employing modern control theory and fuzzy logic, can stop a vehicle efficiently and stably under any condition.

  2. Reactor shielding. Report of a panel

    International Nuclear Information System (INIS)

    Reactor shielding is necessary that people may work and live in the vicinity of reactors without receiving detrimental biological effects and that the necessary materials and instrumentation for reactor operation may function properly. Much of the necessary theoretical work and experimental measurement has been accomplished in recent years. Scientists have developed some very sophisticated methods which have contributed to a more thorough understanding of the problems involved and have produced some very reliable results leading to significant reductions in shield configurations. A panel of experts was convened from 9 to 13 March 1964 in Vienna at the Headquarters of the International Atomic Energy Agency to discuss the present status of reactor shielding. The participants were prominent shielding experts from most of the laboratories engaged in this field throughout the world. They presented status reports describing the past history and plans for further development of reactor shielding in their countries and much valuable discussion took place on some of the most relevant aspects of reactor shielding. All this material is presented in this report, together with abstracts of the supporting papers read to the Panel

  3. Health monitoring system of EWSD exchange using expert system approach

    International Nuclear Information System (INIS)

    Expert systems are practical programs that Use heuristic strategies developed by humans to solve specific classes of problems. The expert system presented in this paper is built for a Portion of EWSD exchange called Line Trunk Group (LTG). LTGs can be used locally with in the exchange or remotely (remote switching unit) in the vicinity of groups of subscribers. They concentrate subscribers' traffic and can be adapted to differing traffic volumes by flexible assignment of subscriber lines as well as PDCs (Primary Digital Carriers) and permit wide-area usage of digital technology. The Purpose of this paper is to utilize the information provided by OMT (Operation and Maintenance Terminals), experts and other system panels to rectify the fault through a well designed Expert System. This will help and guide the operators and technicians by a knowledge based program that provides 'expert quality' solutions to problems in the Line Trunk Group (LTG) of the EWSD Exchange. Such a Decision Support System (DSS) will assist the user in locating and rectifying faults of EWSD exchange in fast and accurate manner. (author)

  4. Diagnosing battery behavior with an expert system in Prolog

    International Nuclear Information System (INIS)

    Power for the Hubble Space Telescope comes from a system of 20 solar panel assemblies (SPAs) and six nickel-cadmium batteries. The HST battery system is simulated by the HST Electrical Power System (EPS) testbed at Marshall Space Flight Center. The Nickel Cadmium Battery Expert System (NICBES) is being used to diagnose faults of the testbed system, evaluate battery status and provide decision support for the engineer. Extensive telemetry of system operating conditions is relayed through a DEC LSI-11, and sent on to an IBM PC-AT. A BASIC program running on the PC monitors the flow of data, figures cell divergence and recharge ratio and stores these values, along with other selected data, for use by the expert system. The expert system is implemented in the logic programming language Prolog. It has three modes of operation: fault diagnosis, status and advice, and decision support. An alert or failure of the system will trigger a diagnosis by the system to assist the operator. The operator can also request battery status information as well as a number of plots and histograms of recent battery behavior. Trends in EOC and EOD voltage, recharge ratio and divergence are used by the expert system in its analysis of battery status. A future enhancement to the system includes the statistical prediction of battery life. Incorporating learning into the expert system is another possible enhancement; This is a difficult task, but one which could promise great rewards in improved battery performance

  5. Cognitive resources of physics experts

    Science.gov (United States)

    Jones, Darrick C.

    One important goal of physics education is to help students develop reasoning patterns similar to those of expert physicists. To achieve this goal, physics educators must know what makes physics experts so successful at solving challenging physics problems. However, this dimension of physics expertise has not been fully explored by the physics education research (PER) community. In this dissertation, I describe several studies I have conducted that further the PER community's understanding of physics expertise. In these studies, I investigate how expert physicists reason as they solve unfamiliar, challenging physics problems by using a resource-based model of cognition to analyze videotaped recordings of problem solving sessions. By developing a way to determine when experts are making conceptual breakthroughs I analyze what resources experts use during conceptual breakthroughs. In the first study, I show that physics conceptual breakthroughs are characterized by reasoning which combines resources related to intuitive knowledge, higher level physics based conceptual knowledge, and epistemological knowledge. In the second study, I develop a way to reliably code for epistemological resources and determine what epistemological resources experts rely on most during conceptual breakthroughs. My findings show that experts rely on contrasting cases more often than any other epistemological resource. In the third study, I use variation theory to investigate how experts use contrasting cases. I look for patterns across all instances when experts use contrasting cases to make a conceptual breakthrough and show how scientific epistemology can be used to better understand experts' use of contrasting cases. I discuss how the findings of each study can be used to inform physics education.

  7. Expert software for accident identification

    International Nuclear Information System (INIS)

    Each type of an accident in a Nuclear Power Plant (NPP) causes immediately after the start of the accident variations of physical parameters that are typical for that type of the accident thus enabling its identification. Examples of these parameter are: decrease of reactor coolant system pressure, increase of radiation level in the containment, increase of pressure in the containment. An expert software enabling a fast preliminary identification of the type of the accident in Krsko NPP has been developed. As input data selected typical parameters from Emergency Response Data System (ERDS) of the Krsko NPP are used. Based on these parameters the expert software identifies the type of the accident and also provides the user with appropriate references (past analyses and other documentation of such an accident). The expert software is to be used as a support tool by an expert team that forms in case of an emergency at Slovenian Nuclear Safety Administration (SNSA) with the task to determine the cause of the accident, its most probable scenario and the source term. The expert software should provide initial identification of the event, while the final one is still to be made after appropriate assessment of the event by the expert group considering possibility of non-typical events, multiple causes, initial conditions, influences of operators' actions etc. The expert software can be also used as an educational/training tool and even as a simple database of available accident analyses.

    General veterinarians such as veterinary officers act as experts at court. They are in so far part of the evidence. Due to his experience the veterinary expert shall give systematical uniform principles concerning even domains adjacent to the field of animal protection such as protection of animal epidemics and food cases, verifiable by science and university research. Examples for expert's topics as well as the requirements of expert reports are shown. According to paragraph 15 II Tierschutzgesetz (Animal Protection Act), as well as according to paragraph paragraph 63, 76 Ordnungswidrigkeitengesetz the experts participation in the proceeding is necessary. In consideration of paragraph paragraph 74, 22 Strafprozessordnung (Code of Criminal Proceedure) conflicts may arise because the veterinarian officer is self-contained investigator, witness as well as expert in the same proceeding. In general the veterinarian officer, who has been involved in the investigations must be excluded from expert activity in the same case. The veterinarian officers have to solve this problem by seperating tasks and functions within one legal case. PMID:15195954

After examining the history and purposes of involving patients in discussions and decision making for research, it outlines the expertise and skills required if panels are to be successful. The paper also analyses existing guidance for panels that include patients. Panels benefit from the experiential knowledge of panel members, craft knowledge of panel facilitators, and organizational knowledge gained through previous experience of hosting panels. Guidance is available that addresses structures and resources (for panel funders and interpersonal communication and group dynamics (for panel members and facilitators. This guidance is most comprehensive when it has itself been developed by all these types of stakeholders.Keywords: public involvement, patient panels, expert panels, guidelines, guidance

  19. Decision Analysis and Expert Systems

    OpenAIRE

    Henrion, Max; Breese, John S.; Horvitz, Eric J.

    1991-01-01

    Decision analysis and expert systems are technologies intended to support human reasoning and decision making by formalizing expert knowledge so that it is amenable to mechanized reasoning methods. Despite some common goals, these two paradigms have evolved divergently, with fundamental differences in principle and practice. Recent recognition of the deficiencies of traditional AI techniques for treating uncertainty, coupled with the development of belief nets and influence diagrams, is stimu...

  20. A theory of expert leadership

    OpenAIRE

    Goodall, Amanda H.

    2012-01-01

    How much knowledge should leaders have of their organization's core business? This is an important question but not one that has been addressed in the management literature. In a new 'theory of expert leadership' (TEL), this paper blends conceptual work with recent empirical evidence. It suggests that organizations perform more effectively when led by individuals who have a deep understanding of the core business of their organization. Being a capable general manager is not sufficient. Expert...

    2004-01-01

    In today's complex world, we have come to rely increasingly on those who have expertise in specific areas and can bring their knowledge to bear on crucial social, political and scientific questions. Taking the viewpoint that experts are consulted when there is something important at stake for an individual, a group, or society at large, Experts in Science and Society explores expertise as a relational concept. How do experts balance their commitment to science with that to society? How does a society actually determine that a person has expertise? What personal traits are valued in an expert? From where does the expert derive authority? What makes new forms of expertise emerge? These and related questions are addressed from a wide range of areas in order to be inclusive, as well as to demonstrate similarities across areas. Likewise, in order to be culturally comparative, this volume includes examples and discussions of experts in different countries and even in different time periods. The topics include the r...

  3. The KN-3000 particle accelerator control expert system (PACES)

    International Nuclear Information System (INIS)

    The particle accelerator control expert system (PACES) is a computer-based operator aid, retrofitted to a model KN-3000 Van de Graaff accelerator, that is used during the start-up, steady state and shut-down phases of the accelerator. Using PACES, the operator can control the accelerator through a graphical control panel, or call upon an expert system to perform automatic start-up or shut-down. PACES then automatically stabilizes and optimizes particle beam parameters. PACES is also able to detect, diagnose and respond to operating faults, such as high-voltage sparks, vacuum system failure or loss of source gas. This paper demonstrates the novel features and utility of the PACES artificial intelligence accelerator controller

    Ciappio, Eric D; Lesser, Mary N R

    2016-01-01

    In today's world in which there is a surplus of both scientists and online nutrition "experts," how do young professionals establish themselves? Becoming established as an expert requires selling yourself and your ideas to your colleagues and the general public by using effective communication skills. Helping young professionals develop these skills was the goal of a panel held at the ASN Scientific Sessions and Annual Meeting at Experimental Biology 2015. This panel featured a set of distinguished speakers who discussed techniques and strategies to enhance professional reputations centered around effectively leveraging communication platforms and opportunities to engage with colleagues. Early-career nutrition scientists can use the guidance provided by the panelists to improve their visibility and be a champion for themselves in order to establish themselves as experts in the field.

    This article describes the conclusions of an expert panel that discussed four case studies; these were examples of patients typically encountered by nurses working in the community. The panel considered the nutritional and lifestyle advice that could be given by nurses relating to conditions such as irritable bowel syndrome (IBS), depression, chronic fatigue syndrome, vulnerability to common infections, elderly care, recurrent urinary tract infection, antibiotic use, and risk of type 2 diabetes. A general conclusion was the importance of motivational interviewing techniques in achieving full understanding of patients' concerns and to determine the best health strategy. As well as specific guidance appropriate for each disorder, a range of information sources for both health professionals and patients are listed in the paper. The panel noted that, although general nutritional advice can be given by nurses working at GP surgeries and in the community, patients should always be referred to registered dietitians or nutritionists if significant dietary changes are considered.

  7. Expert Consensus Contouring Guidelines for Intensity Modulated Radiation Therapy in Esophageal and Gastroesophageal Junction Cancer

    International Nuclear Information System (INIS)

    Purpose/Objective(s): Current guidelines for esophageal cancer contouring are derived from traditional 2-dimensional fields based on bony landmarks, and they do not provide sufficient anatomic detail to ensure consistent contouring for more conformal radiation therapy techniques such as intensity modulated radiation therapy (IMRT). Therefore, we convened an expert panel with the specific aim to derive contouring guidelines and generate an atlas for the clinical target volume (CTV) in esophageal or gastroesophageal junction (GEJ) cancer. Methods and Materials: Eight expert academically based gastrointestinal radiation oncologists participated. Three sample cases were chosen: a GEJ cancer, a distal esophageal cancer, and a mid-upper esophageal cancer. Uniform computed tomographic (CT) simulation datasets and accompanying diagnostic positron emission tomographic/CT images were distributed to each expert, and the expert was instructed to generate gross tumor volume (GTV) and CTV contours for each case. All contours were aggregated and subjected to quantitative analysis to assess the degree of concordance between experts and to generate draft consensus contours. The panel then refined these contours to generate the contouring atlas. Results: The κ statistics indicated substantial agreement between panelists for each of the 3 test cases. A consensus CTV atlas was generated for the 3 test cases, each representing common anatomic presentations of esophageal cancer. The panel agreed on guidelines and principles to facilitate the generalizability of the atlas to individual cases. Conclusions: This expert panel successfully reached agreement on contouring guidelines for esophageal and GEJ IMRT and generated a reference CTV atlas. This atlas will serve as a reference for IMRT contours for clinical practice and prospective trial design. Subsequent patterns of failure analyses of clinical datasets using these guidelines may require modification in the future

    1988-01-01

    Artificial intelligence (AI) technology, and in particular expert systems, has shown potential applicability in many areas of operation at the Kennedy Space Center (KSC). In an era of limited resources, the early identification of good expert system applications, and their segregation from inappropriate ones can result in a more efficient use of available NASA resources. On the other hand, the education of students in a highly technical area such as AI requires an extensive hands-on effort. The nature of expert systems is such that proper sample applications for the educational process are difficult to find. A pilot project between NASA-KSC and the University of Central Florida which was designed to simultaneously address the needs of both institutions at a minimum cost. This project, referred to as Expert Systems Prototype Training Project (ESPTP), provided NASA with relatively inexpensive development of initial prototype versions of certain applications. University students likewise benefit by having expertise on a non-trivial problem accessible to them at no cost. Such expertise is indispensible in a hands-on training approach to developing expert systems.

  13. Expert systems and nuclear safety

    International Nuclear Information System (INIS)

    The US Nuclear Regulatory Commission (NRC) and the Electric Power Research Institute have initiated a broad-based exploration of means to evaluate the potential applications of expert systems in the nuclear industry. This exploratory effort will assess the use of expert systems to augment the diagnostic and decision-making capabilities of personnel with the goal of enhancing productivity, reliability, and performance. The initial research effort is the development and documentation of guidelines for verifying and validating (V and V) expert systems. An initial application of expert systems in the nuclear industry is to aid operations and maintenance personnel in decision-making tasks. The scope of the decision aiding covers all types of cognitive behavior consisting of skill, rule, and knowledge-based behavior. For example, procedure trackers were designed and tested to support rule-based behavior. Further, these systems automate many of the tedious, error-prone human monitoring tasks, thereby reducing the potential for human error. The paper version of the procedure contains the knowledge base and the rules and thus serves as the basis of the design verification of the procedure tracker. Person-in-the-loop tests serve as the basis for the validation of a procedure tracker. When conducting validation tests, it is important to ascertain that the human retains the locus of control in the use of the expert system

  14. Expert systems in clinical practice

    International Nuclear Information System (INIS)

    The first expert systems prototypes intended for advising physicians on diagnosis or therapy selection have been designed more than ten years ago. However, a few of them are already in use in clinical practice after years of research and development efforts. The capabilities of these systems to reason symbolically and to mimic the hypothetico-deductive processes used by physicians distinguishes them from conventional computer programs. Their power comes from their knowledge-base which embeds a large quantity of high-level, specialized knowledge captured from medical experts. Common methods for knowledge representation include production rules and frames. These methods also provide a mean for organizing and structuring the knowledge according to hierarchical or causal links. The best expert-systems perform at the level of the experts. They are easy to learn and use, and can communicate with the user in pseudo-natural language. Moreover they are able to explain their line of reasoning. These capabilities make them potentially useful, usable and acceptable by physicians. However if the problems related to difficulties and costs in building expert-systems are on the way to be solved within the next few years, forensic and ethical issues should have to be addressed before one can envisage their routine use in clinical practice

    1996-03-01

    The design of many industrial and engineering systems can often be accomplished using flow graphs of various types. Examples include manufacturing processes and data processing applications, Graph Transformation Expert System, is an expert system which has been developed by WUT for applying techniques of artificial intelligence to the architectural design of data and signal processing systems. Software and hardware architectures may be defined for such systems using data flow graphs, in which nodes represent data processing steps and directed areas represent the `flow' of data between the processing steps. Starting with a user- defined generic processing graphic, this expert will transform the graph by applying transformation rules in order to specialize the processing graph to satisfy specified design goals and/or hardware constraints. Although the particular application for which this expert is designed is that of data and signal processing systems, it can provide an expert system framework for other problems specified graphically; for example, manufacturing systems, information systems, and product distribution systems.

    The feasibility of using expert systems as an aid in regulatory compliance functions has been investigated. A literature review was carried out to identify applications of expert systems to regulatory affairs. A bibliography of the small literature on such applications was prepared. A prototype system, ARIES, was developed to demonstrate the use of an expert system as an aid to a Project Officer in assuring compliance with licence requirements. The system runs on a personal computer with a graphical interface. Extensive use is made of hypertext to link interrelated rules and requirements as well as to provide an explanation facility. Based on the performance of ARIES the development of a field version is recommended

    2015-12-01

    Acute renal failure (ARF) in critically ill patients is currently very frequent and requires renal replacement therapy (RRT) in many patients. During the last 15 years, several studies have considered important issues regarding the use of RRT in ARF, like the time to initiate the therapy, the dialysis dose, the types of catheter, the choice of technique, and anticoagulation. However, despite an abundant literature, conflicting results do not provide evidence on RRT implementation. We present herein recommendations for the use of RRT in adult and pediatric intensive care developed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system by an expert group of French Intensive Care Society (SRLF), with the participation of the French Society of Anesthesia and Intensive Care (SFAR), the French Group for Pediatric Intensive Care and Emergencies (GFRUP), and the French Dialysis Society (SFD). The recommendations cover 4 fields: criteria for RRT initiation, technical aspects (access routes, membranes, anticoagulation, reverse osmosis water), practical aspects (choice of the method, peritoneal dialysis, dialysis dose, adjustments), and safety (procedures and training, dialysis catheter management, extracorporeal circuit set-up). These recommendations have been designed on a practical point of view to provide guidance for intensivists in their daily practice. PMID:26714808

  19. The making of an expert.

    Ericsson, K Anders; Prietula, Michael J; Cokely, Edward T

    2007-01-01

    Popular lore tells us that genius is born, not made. Scientific research, on the other hand, reveals that true expertise is mainly the product of years of intense practice and dedicated coaching. Ordinary practice is not enough: To reach elite levels of performance, you need to constantly push yourself beyond your abilities and comfort level. Such discipline is the key to becoming an expert in all domains, including management and leadership. Those are the conclusions reached by Ericsson, a professor of psychology at Florida State University; Prietula, a professor at the Goizueta Business School; and Cokely, a research fellow at the Max Planck Institute for Human Development, who together studied data on the behavior of experts, gathered by more than 100 scientists. What consistently distinguished elite surgeons, chess players, writers, athletes, pianists, and other experts was the habit of engaging in "deliberate" practice--a sustained focus on tasks that they couldn't do before. Experts continually analyzed what they did wrong, adjusted their techniques, and worked arduously to correct their errors. Even such traits as charisma can be developed using this technique. Working with a drama school, the authors created a set of acting exercises for managers that remarkably enhanced executives' powers of charm and persuasion. Through deliberate practice, leaders can improve their ability to win over their employees, their peers, or their board of directors. The journey to elite performance is not for the impatient or the faint of heart. It takes at least a decade and requires the guidance of an expert teacher to provide tough, often painful feedback. It also demands would-be experts to develop their "inner coach" and eventually drive their own progress. PMID:17642130

    Tonn, B.; MacGregor, D.

    1986-01-01

    This paper discusses psychological problems relevant to developing and designing expert systems. With respect to the former, the psychological literature suggests that several cognitive biases may affect the elicitation of a valid knowledge base from the expert. The literature also suggests that common expert system inference engines may be quite inconsistent with reasoning heuristics employed by experts. With respect to expert system user interfaces, care should be taken when eliciting uncertainty estimates from users, presenting system conclusions, and ordering questions.

    Microsphere insulation panels (MIPs) have been developed as lightweight, longlasting replacements for the foam and vacuum-jacketed systems heretofore used for thermally insulating cryogenic vessels and transfer ducts. The microsphere core material of a typical MIP consists of hollow glass bubbles, which have a combination of advantageous mechanical, chemical, and thermal-insulation properties heretofore available only separately in different materials. In particular, a core filling of glass microspheres has high crush strength and low density, is noncombustible, and performs well in soft vacuum.

    Mutschler, Jr., Edward Charles (Inventor)

    1998-01-01

    A spacecraft includes a plurality of solar panels interconnected with a power coupler and an electrically operated device to provide power to the device when the solar cells are insolated. The solar panels are subject to bending distortion when entering or leaving eclipse. Spacecraft attitude disturbances are reduced by mounting each of the solar panels to an elongated boom made from a material with a low coefficient of thermal expansion, so that the bending of one panel is not communicated to the next. The boom may be insulated to reduce its bending during changes in insolation. A particularly advantageous embodiment mounts each panel to the boom with a single mounting, which may be a hinge. The single mounting prevents transfer of bending moments from the panel to the boom.

  13. Expert judgement in performance assessment

    International Nuclear Information System (INIS)

    This report is a pilot study that systematically describes the various types of expert judgement that are made throughout the development of a PA, and summarizes existing tools and practices for dealing with expert judgements. The report also includes recommendations for further work in the area of expert judgement. Expert judgements can be classified in a number of ways, including classification according to why the judgements are made and according to how the judgements are made. In terms of why judgements are made, there is a broad distinction between: Judgements concerning data that are made because alternatives are not feasible; and Judgements about the conduct of a PA that are made because there are no alternative approaches for making the decision. In the case of how judgements are made, the report distinguishes between non-elicited judgements made by individuals, non-elicited judgements made by groups, and elicited judgements made by individuals or groups. These types of judgement can generally be distinguished by the extent of the associated documentation, and hence their traceability. Tools for assessing judgements vary depending on the type of judgements being examined. Key tools are peer review, an appropriate QA regime, documentation, and elicitation. Dialogue with stake holders is also identified as important in establishing whether judgements are justified in the context in which they are used. The PA process comprises a number of stages, from establishing the assessment context, through site selection and repository design, to scenario and model development and parametrisation. The report discusses how judgements are used in each of these stages, and identifies which of the tools and procedures for assessing judgements are most appropriate at each stage. Recommendations for further work include the conduct of a trial expert elicitation to gain experience in the advantages and disadvantages of this technique, the development of guidance for peer

    Full Text Available No abstract available. Article truncated after 150 words. In this month's Pulmonary Journal Club Dr. Mathew reviews an article by Feuerstein et al. (1 from Beth Israel Deaconess Medical Center and Harvard Medical School published in the Mayo Clinic Proceedings (2. The authors reviewed the evidence basis for 153 interventional guidelines including 2 from the American College of Chest Physicians and the American Thoracic Society. Of the 3425 recommendations reviewed, 11% were supported by level A evidence, 42% by level B, and 48% by level C. These numbers are very close to the results published by Lee and Vielemeyer (3 for the Infectious Disease Society of America guidelines where only 14% of the guidelines were based on level A evidence and 55% by level C. So what's wrong with the majority of guidelines based on expert opinion? After all, these are experts in the field and it can be argued that most of these opinions are probably right ...

  16. Expert system based radionuclide identification

    International Nuclear Information System (INIS)

    An expert system coupled with the gamma spectrum analysis system SAMPO has been developed for automating the qualitative identification of radionuclides as well as for determining the quantitative parameters of the spectrum components. The program is written in C-language and runs in various environments ranging from PCs to UNIX workstations. The expert system utilizes a complete gamma library with over 2600 nuclides and 80,000 lines, and a rule base of about fifty criteria including energies, relative peak intensities, genesis modes, half lives, parent-daughter relationships, etc. The rule base is furthermore extensible by the user. This is not an original contribution but a somewhat updated version of papers and reports previously published elsewhere. (author)

    Regarding the liability of the expert witness, is has to be differentiated between the responsibility according to the civil law and the criminal law. Responsibility in the criminal law means the punishableness for the guilty and illegal fulfillment of a criminal offense in the legal sense, while responsibility in the civil law means compensation towards another citizen. Criminal prosecution occurs ex officio. Prerequisite for prosecution in the civil law is an action of the victim. PMID:9064937

    The generally weak correlation between board independence and firm performance is a major empirical puzzle. One possible explanation is that director independence alone is not enough. To explore this possibility, we examine the full employment histories of independent directors at S&P 1500 companies. We define an independent expert director (IED) as an independent director who has worked in the same 2-digit SIC industry as the company where he/she serves as an independent director. We show th...

  1. Uncertainty reasoning in expert systems

    Science.gov (United States)

    Kreinovich, Vladik

    1993-01-01

    Intelligent control is a very successful way to transform the expert's knowledge of the type 'if the velocity is big and the distance from the object is small, hit the brakes and decelerate as fast as possible' into an actual control. To apply this transformation, one must choose appropriate methods for reasoning with uncertainty, i.e., one must: (1) choose the representation for words like 'small', 'big'; (2) choose operations corresponding to 'and' and 'or'; (3) choose a method that transforms the resulting uncertain control recommendations into a precise control strategy. The wrong choice can drastically affect the quality of the resulting control, so the problem of choosing the right procedure is very important. From a mathematical viewpoint these choice problems correspond to non-linear optimization and are therefore extremely difficult. In this project, a new mathematical formalism (based on group theory) is developed that allows us to solve the problem of optimal choice and thus: (1) explain why the existing choices are really the best (in some situations); (2) explain a rather mysterious fact that fuzzy control (i.e., control based on the experts' knowledge) is often better than the control by these same experts; and (3) give choice recommendations for the cases when traditional choices do not work.

  2. Panel summary report

    International Nuclear Information System (INIS)

    Previous Advisory Group Meetings have led to IAEA Technical Reports No.15=5 (1974) on thermal discharge, 118 (1970) and 169 (1975) on sampling, storage and analysis methods for marine radioactivity studies, 167 (1975) on design of marine biological studies permitting comparative evaluation, and 172 (1976) on the effects of ionizing radiation on aquative organisms and eco-systems. The aim of the present report was a bringing into perspective not only problems designing radioecological experiments but to describe reliable experimental methodology suitable for a successful evaluation of radioactivity cycling, and of the effects of such radioactive additions to aquatic environments, as a result of nuclear activities. Specific examples are described. Individual studies presented to the Panel have been treated in detail, and constitute 19 separate INIS entries

  3. Can journalistic "false balance" distort public perception of consensus in expert opinion?

    Science.gov (United States)

    Koehler, Derek J

    2016-03-01

    Media critics have expressed concern that journalistic "false balance" can distort the public's perceptions of what ought to be noncontroversial subjects (e.g., climate change). I report several experiments testing the influence of presenting conflicting comments from 2 experts who disagree on an issue (balance condition) in addition to a complete count of the number of experts on a panel who favor either side. Compared with a control condition, who received only the complete count, participants in the balance condition gave ratings of the perceived agreement among the experts that did not discriminate as clearly between issues with and without strong expert consensus. Participants in the balance condition also perceived less agreement among the experts in general, and were less likely to think that there was enough agreement among experts on the high-consensus issues to guide government policy. Evidently, "false balance" can distort perceptions of expert opinion even when participants would seem to have all the information needed to correct for its influence.

  6. WEB TECHNOLOGY CONVERGENTE WITH EXPERT SYSTEMS

    Directory of Open Access Journals (Sweden)

    Diana-Aderina MOISUC

    2014-11-01

    Full Text Available From the first applications to this day, expert systems have obtained remarkable results in many areas, by using knowledge extracted and transferred from human experts. The main reason behind the advent of expert systems was the potential to provide recommendations to a large number of users. In today’s world, the spread of the Internet and web applications generated an exponential growth of the quantity of information that needs to be processed by an increasing number of users. Under these circumstances emerged the convergence of web technologies with expert systems, resulting in the category of web based expert systems. The potential of traditional expert systems was harnessed by using web technologies, offering new ways of disseminating expertise and knowledge to a mass audience. In this paper we will first review base concepts and features of traditional expert systems and then point out the benefits brought by the development and the use of web based expert systems.

  7. Galaxy Classification: Citizen Scientists versus Experts

    Kautsch, Stefan J.; Vazquez, Richard; Phung, Chau; VanHilst, Michael; Castro, Victor H.; Bizyaev, Dmitry

    2016-01-01

    We present the differences of morphological galaxy classification between non-experts and experts. The non-experts are represented by college students and a retired adult community, who use an online application to visually classify galaxies selected from a galaxy morphology catalog. We find that the non-expert group lags the expert classification by one Hubble type behind, for instance, the non-experts classify a set of galaxies with Sb, while the experts classify the same set as Sc. We believe the reason is because the Hubble sequence is increasing the asymmetric structures towards later types. Our results show that the experts have the ability to identify more detailed structures, which the laymen commonly do not recognize.

    2012-02-01

    Expert knowledge is used widely in the science and practice of conservation because of the complexity of problems, relative lack of data, and the imminent nature of many conservation decisions. Expert knowledge is substantive information on a particular topic that is not widely known by others. An expert is someone who holds this knowledge and who is often deferred to in its interpretation. We refer to predictions by experts of what may happen in a particular context as expert judgments. In general, an expert-elicitation approach consists of five steps: deciding how information will be used, determining what to elicit, designing the elicitation process, performing the elicitation, and translating the elicited information into quantitative statements that can be used in a model or directly to make decisions. This last step is known as encoding. Some of the considerations in eliciting expert knowledge include determining how to work with multiple experts and how to combine multiple judgments, minimizing bias in the elicited information, and verifying the accuracy of expert information. We highlight structured elicitation techniques that, if adopted, will improve the accuracy and information content of expert judgment and ensure uncertainty is captured accurately. We suggest four aspects of an expert elicitation exercise be examined to determine its comprehensiveness and effectiveness: study design and context, elicitation design, elicitation method, and elicitation output. Just as the reliability of empirical data depends on the rigor with which it was acquired so too does that of expert knowledge. PMID:22280323

  17. Evaluation of proposed panel closure modifications at WIPP

    Energy Technology Data Exchange (ETDEWEB)

    Allen, Lawrence E.; Silva, Matthew K.; Channell, James K.; Abel, John F.; Morgan, Dudley R.

    2001-12-31

    A key component in the design of the WIPP repository is the installation of concrete structures as panel seals in the intake and exhaust drifts after a panel has been filled with waste containers. As noted in the EPA final rule, the panel seal closure system is intended to block brine flow between the waste panels at the WIPP. On April 17, 2001, the DOE proposed seven modifications to the EPA concerning the design of the panel closure system. EPA approval of these modifications is necessary since the details of the panel design are specified in EPA’s final rule as a condition for WIPP certification. However, the EPA has not determined whether a rulemaking would be required for these proposed design modifications. On September 4, 2001, the DOE withdrew the request, noting that it would be resubmitted on a future date. The Environmental Evaluation Group (EEG) contracted with two engineers, Dr. John Abel and Dr. Rusty Morgan, to evaluate the proposed modifications. The EEG has accepted the conclusions and recommendations from these two experts: 1) replacement of Salado Mass Concrete with a generic salt-based concrete; 2) replacement of the explosion wall with a construction wall; 3) replacement of freshwater grouting with salt-based grouting; 4) option to allow surface or underground mixing; and 5) option to allow up to one year for completion of closure. The proposed modification to allow local carbonate river rock as aggregate is acceptable pending demonstration that no problems will exist in the resulting concrete. The proposed modification to give the contractor discretion in removal of steel forms is not supported. Instead, several recommendations are made to specifically reduce the number of forms left, thereby reducing potential migration pathways.

    A risk-based expert-system development methodology has been developed to provide guidance to managers and technical personnel and to serve as a standard for developing expert systems. Expert-system development differs from conventional software development in that the information needed to prepare system requirements for expert systems is not known at the outset of a project and is obtained by knowledge engineering methods. The paper describes the expert-system life cycle, development methodology, and the approach taken in this methodology to manage and reduce the risks in expert system development. Also examined are the risks of using and of not using a methodology, the studies undertaken to validate the provisions of the expert system development methodology, and the results of these validation studies.

    Over the past 10 to 15 years, the availability of new materials and technologies has resulted in revolutionary concepts for contact lenses being proposed that go well beyond correcting vision. These novel uses include their prescribing to deliver topical ocular and systemic drugs, assist with ocular surface disease management, and limit the progression of myopia and novel methods to display visual information. How likely are these concepts to become commercially available, how successful will they be, and what are the potential issues to consider for them to come to market? To answer these questions, a panel of four experts were invited to discuss the benefits and pitfalls of these technologies and what challenges lay ahead of these concepts before their availability. Their responses provide a fascinating insight for the clinician into the likelihood of such revolutionary contact lenses being available in a clinical setting. PMID:26390344

  6. Neural network based expert system for fault diagnosis of particle accelerators

    International Nuclear Information System (INIS)

    Particle accelerators are generators that produce beams of charged particles, acquiring different energies, depending on the accelerator type. The MGC-20 cyclotron is a cyclic particle accelerator used for accelerating protons, deuterons, alpha particles, and helium-3 to different energies. Its applications include isotope production, nuclear reaction, and mass spectroscopy studies. It is a complicated machine, it consists of five main parts, the ion source, the deflector, the beam transport system, the concentric and harmonic coils, and the radio frequency system. The diagnosis of this device is a very complex task. it depends on the conditions of 27 indicators of the control panel of the device. The accurate diagnosis can lead to a high system reliability and save maintenance costs. so an expert system for the cyclotron fault diagnosis is necessary to be built. In this thesis , a hybrid expert system was developed for the fault diagnosis of the MGC-20 cyclotron. Two intelligent techniques, multilayer feed forward back propagation neural network and the rule based expert system, are integrated as a pre-processor loosely coupled model to build the proposed hybrid expert system. The architecture of the developed hybrid expert system consists of two levels. The first level is two feed forward back propagation neural networks, used for isolating the faulty part of the cyclotron. The second level is the rule based expert system, used for troubleshooting the faults inside the isolated faulty part. 4-6 tabs., 4-5 figs., 36 refs

A consideration of the common traits in the recent history of these studies, with reference to the use of computers on texts in natural language motivates the introduction of set theoretic and algebraic methods, suitable for applications in the analysis and in the automatic treatment of languages, based on the concept of model sets and on relational structures suggested from the connections between syntax and semantics evidenced in some example of sub-languages corresponding to theories of different classes of physical phenomena. Some details of these methods are evidenced, which have already successfully used or whose applications appears suggestive of interesting development.

An expert system prototype has been developed to automate waste NDA data review of a passive/active neutron drum counter system. The expert system is designed to yield a confidence rating regarding measurement validity. Expert system rules are derived from data in a process involving data clustering, fuzzy logic, and genetic algorithms. Expert system performance is assessed against confidence assignments elicited from waste NDA domain experts. Performance levels varied for the active, passive shielded, and passive system assay modes of the drum counter system, ranging from 78% to 94% correct classifications

  16. Analysis of 3-panel and 4-panel microscale ionization sources

    International Nuclear Information System (INIS)

    Two designs of a microscale electron ionization (EI) source are analyzed herein: a 3-panel design and a 4-panel design. Devices were fabricated using microelectromechanical systems technology. Field emission from carbon nanotube provided the electrons for the EI source. Ion currents were measured for helium, nitrogen, and xenon at pressures ranging from 10-4 to 0.1 Torr. A comparison of the performance of both designs is presented. The 4-panel microion source showed a 10x improvement in performance compared to the 3-panel device. An analysis of the various factors affecting the performance of the microion sources is also presented. SIMION, an electron and ion optics software, was coupled with experimental measurements to analyze the ion current results. The electron current contributing to ionization and the ion collection efficiency are believed to be the primary factors responsible for the higher efficiency of the 4-panel microion source. Other improvements in device design that could lead to higher ion source efficiency in the future are also discussed. These microscale ion sources are expected to find application as stand alone ion sources as well as in miniature mass spectrometers.

    Full Text Available Abstract Background Delphi surveys with panels of experts in a particular area of interest have been widely utilized in the fields of clinical medicine, nursing practice, medical education and healthcare services. Despite this wide applicability of the Delphi methodology, there is no clear identification of what constitutes a sufficient number of Delphi survey participants to ensure stability of results. Methods The study analyzed the response characteristics from the first round of a Delphi survey conducted with 23 experts in healthcare quality and patient safety. The panel members had similar training and subject matter understanding of the Malcolm Baldrige Criteria for Performance Excellence in Healthcare. The raw data from the first round sampling, which usually contains the largest diversity of responses, were augmented via bootstrap sampling to obtain computer-generated results for two larger samples obtained by sampling with replacement. Response characteristics (mean, trimmed mean, standard deviation and 95% confidence intervals for 54 survey items were compared for the responses of the 23 actual study participants and two computer-generated samples of 1000 and 2000 resampling iterations. Results The results from this study indicate that the response characteristics of a small expert panel in a well-defined knowledge area are stable in light of augmented sampling. Conclusion Panels of similarly trained experts (who possess a general understanding in the field of interest provide effective and reliable utilization of a small sample from a limited number of experts in a field of study to develop reliable criteria that inform judgment and support effective decision-making.

    After the end of the Cold War, the United Nations, some individual governments, non-govermental research organizations and academia began to focus increased attention on light weapons as an arms control proliferation issue particularly within the context of intrastate warfare and destabilizing criminal activities. In 1995 the Secretary-General to the Security Council in a report entitled, An Agenda for Peace stressed the need for 'practical disarmament in the context of the conflicts that the UN is actually dealing with and of the weapons most of them light weapons, that are actually killing people in the hundreds of thousands. Light weapons and small arms have been the subject of some 12 UN resolutions and documents among them, UN Resolution 49175M which addressed illicit arms trafficking and Annex I of UN Document A151142 which provided 'Guidelines for International Arms Transfers.' Within a different context, the UN Commission on Crime Prevention and Criminal Justice in Vienna recently made recommendations on the impact of small arms, primarily within the framework of criminal activities, accidents and suicides, illicit firearms trafficking, and domestic, regional and interregional firearms regulations. On 12 December 1995, Japan introduced Resolution 50/01/70 B which was the first attempt by the UN to clearly address small arms and light weapons as an arms control issue. (author)

    Vaccines are among the most cost-effective interventions against infectious diseases. Many candidate vaccines targeting neglected diseases in low- and middle-income countries are now progressing to large-scale clinical testing. However, controversy surrounds the appropriate design of vaccine trials and, in particular, the use of unvaccinated controls (with or without placebo) when an efficacious vaccine already exists. This paper specifies four situations in which placebo use may be acceptable, provided that the study question cannot be answered in an active-controlled trial design; the risks of delaying or foregoing an efficacious vaccine are mitigated; the risks of using a placebo control are justified by the social and public health value of the research; and the research is responsive to local health needs. The four situations are: (1) developing a locally affordable vaccine, (2) evaluating the local safety and efficacy of an existing vaccine, (3) testing a new vaccine when an existing vaccine is considered inappropriate for local use (e.g. based on epidemiologic or demographic factors), and (4) determining the local burden of disease.

    Family physicians are the primary and sometimes only health care resource for families affected by sickle cell disease. Recently published guidelines provide important recommendations for health maintenance, acute care, and monitoring of disease-modifying therapy in persons with this condition. This overview highlights some of the most important clinical activities that can and should be carried out in the community care setting. Children with sickle cell anemia should receive prophylactic penicillin from birth through at least five years of age, and all persons with sickle cell disease require vaccination to prevent invasive pneumococcal disease. Annual screening with transcranial Doppler ultrasonography is recommended for all children with sickle cell disease beginning at two years of age and continuing through adolescence to evaluate the risk of stroke and to initiate transfusion therapy in those at high risk. Vasoocclusive crises require immediate and adequate analgesia appropriate to the level of patient-reported pain. Antibiotics, hospitalization, and incentive spirometry are indicated for those with acute chest syndrome. There is strong evidence to support the promotion and use of hydroxyurea therapy in patients nine months and older who have sickle cell anemia because its use can decrease the frequency of vasoocclusive crises and acute chest syndrome with limited adverse effects.

  19. An analysis framework for radioactive waste management incorporating expert judgment

    International Nuclear Information System (INIS)

    led directly to the development of a risk model for double shell tanks. At least two rather different physical processes in the tanks were identified as potentially leading to large episodic releases. Since any one of several stimuli could trigger these processes, it was necessary to model internal tank phenomena, external natural phenomena, and tank intrusive operations. The uncertain parameters varied across a range that included parameters of the waste, parameters describing the frequencies and intensities of natural phenomena (e.g., earthquakes), and parameters describing intentional and accidental human activity. In order to capture an authoritative uncertainty distribution for each type of parameter, it was necessary to assemble an expert panel with a very wide range of expertise (Full text of contribution)

    International Nuclear Information System (INIS)

    Electric utilities are being subjected to unprecedented pressures to justify their prudence and/or reasonableness in managing outage, operation, and construction activities at their generating facilities. Frequently, management decision justification in rate case or legal proceedings is highly dependent on expert judgment. Fluor Daniel has applied decision analysis methods to quantify expert judgments on the reasonableness of management decisions. These complement experts' qualitative thinking and reasoning by analyzing the components of a complex management problem with an uncertain outcome. Quantification methods lend themselves to synthesizing information from several technical disciplines with clear communication of the experts' thinking and reasoning

  1. BWR recirculation pump diagnostic expert system

    International Nuclear Information System (INIS)

    At General Electric (GE), an on-line expert system to support maintenance decisions for BWR recirculation pumps for nuclear power plants has been developed. This diagnostic expert system is an interactive on-line system that furnishes diagnostic information concerning BWR recirculation pump operational problems. It effectively provides the recirculation pump diagnostic expertise in the plant control room continuously 24 hours a day. The expert system is interfaced to an on-line monitoring system, which uses existing plant sensors to acquire non-safety related data in real time. The expert system correlates and evaluates process data and vibration data by applying expert rules to determine the condition of a BWR recirculation pump system by applying knowledge based rules. Any diagnosis will be automatically displayed, indicating which pump may have a problem, the category of the problem, and the degree of concern expressed by the validity index and color hierarchy. The rules incorporate the expert knowledge from various technical sources such as plant experience, engineering principles, and published reports. These rules are installed in IF-THEN formats and the resulting truth values are also expressed in fuzzy terms and a certainty factor called a validity index. This GE Recirculation Pump Expert System uses industry-standard software, hardware, and network access to provide flexible interfaces with other possible data acquisition systems. Gensym G2 Real-Time Expert System is used for the expert shell and provides the graphical user interface, knowledge base, and inference engine capabilities. (author)

  3. Cooperative expert system reasoning for waste remediations

    International Nuclear Information System (INIS)

    The United States Department of Energy (DOE) is facing a large task in completing Remedial Investigations and Feasibility Studies (RI/FS) for hazardous waste sites across the nation. One of the primary objectives of an RI/FS is the specification of viable sequences of technology treatment trains which can provide implementable site solutions. We present a methodology which integrates expert system technology within an object-oriented framework to create a cooperative reasoning system designed to provide a comprehensive list of these implementable solutions. The system accomplishes its goal of specifying technology trains by utilizing a ''team'' of expert system objects. The system distributes the problem solving among the individual expert objects, and then coordinates the combination of individual decisions into a joint solution. Each expert object possesses the knowledge of an expert in a particular technology. An expert object can examine the parameters and characteristics of the waste site, seek information and support from other expert objects, and then make decisions concerning its own applicability. This methodology has at least two primary benefits. First, the creation of multiple expert objects provides a more direct mapping from the actual process to a software system, making the system easier to build. Second, the distribution of the inferencing among a number of loosely connected expert objects allows for a more robust and maintainable final product

    . The expert group reviewed and analyzed the existing evidence, consensus recommendations, and Russian experts’ extensive practical experience of incobotulinumtoxinA in aesthetics to reach consensus on optimal doses, potential dose adjustments, and injection sites of incobotulinumtoxinA for facial aesthetics. Results: All experts developed guidance on the optimal doses for incobotulinumtoxinA treatment of different regions of the upper and lower face. The expert panel agreed that there are no differences in the efficacy and duration of the effect between the four BoNT/As that are commercially available for facial aesthetic indications in Russia and that, when administered correctly, all BoNT/As can achieve optimal results. Experts also agreed that nonresponse to BoNT/A can be caused by neutralizing antibodies. Conclusion: On the basis of the scientific and clinical evidence available for incobotulinumtoxinA, coupled with the extensive clinical experience of the consensus group, experts recommended the optimal doses of incobotulinumtoxinA effective for treatment of wrinkles of the upper and lower face to achieve the expected aesthetic outcome. These first Russian guidelines on the optimal use of incobotulinumtoxinA for augmentation of glabellar lines, periorbital wrinkles, forehead lines, bunny lines, perioral wrinkles, depressor anguli oris, mentalis, masseters and platysmal bands, and performing the Nefertiti lift, are presented here.

  10. Uncertainty in geological linework: communicating the expert's tacit model to the data user(s) by expert elicitation.

    Lawley, Russell; Barron, Mark; Lark, Murray

    2015-04-01

    At BGS, expert elicitation has been used to evaluate uncertainty of surveyed boundaries in several, common, geological scenarios. As a result, a 'collective' understanding of the issues surrounding each scenario has emerged. The work has provoked wider debate in three key areas: a) what can we do to resolve those scenarios where a 'consensus' of understanding cannot be achieved b) what does it mean for survey practices and subsequent use of maps in 3D models c) how do we communicate the 'collective' understanding of geological mapping (with or without consensus for specific scenarios). Previous work elicited expert judgement for uncertainty in six contrasting mapping scenarios. In five cases it was possible to arrive at a consensus model; in a sixth case experts with different experience (length of service, academic background) took very different views of the nature of the mapping problem. The scenario concerned identification of the boundary between two contrasting tills (one derived from Triassic source materials being red in colour; the other, derived from Jurassic materials being grey in colour). Initial debate during the elicitation identified that the colour contrast should provide some degree of confidence in locating the boundary via traditional auger-traverse survey methods. However, as the elicitation progressed, it became clear that the complexities of the relationship between the two Tills were not uniformly understood across the experts and the panel could not agree a consensus regarding the spatial uncertainty of the boundary. The elicitation process allowed a significant degree of structured knowledge-exchange between experts of differing backgrounds and was successful in identifying a measure of uncertainty for what was considered a contentious scenario. However, the findings have significant implications for a boundary-scenario that is widely mapped across the central regions of Great Britain. We will discuss our experience of the use of

We are developing a method for noise control, using an array of panels of magnetostrictive Metglas, which combines the low mass and flexibility of active noise control with the relatively low cost and simplicity of passive noise control. The method is based on the well known fact that an acoustic panel with a reaction mass, resonant at the frequency of the sound wave, will completely reflect that wave, simulating an infinite mass. By wrapping a coil around each Metglas panel, and terminating the coil in an impedance, the stiffness of the Metglas, and hence the resonant frequency of the panel, can be controlled by varying the terminal impedance. By choosing a terminal impedance which is itself frequency dependent, the panel can be made to resonate, and hence to have effective infinite mass, at all frequencies (over some fairly large range) simultaneously. This generally requires negative impedance, which can be produced by a simple circuit with an amplifier and feedback loop. In effect, the Metglas acts like both microphone and speaker in an active noise control system. Preliminary experimental results will be presented.

  12. [Medical expert opinion--credibility, ethics, remuneration].

    Israeli Law requires a Personal Injury Claim to be supported by an Expert Medical Opinion. Such evidence provides the Court with information essential for the evaluation of scientific material, which is beyond the Court's "judicial knowledge". Incongruent Expert Opinions are not necessarily the result of deceit. Experts are entitled to differences in their respective evaluation and interpretation of data and conflicting medical opinions may be legitimate. The Court's duty and prerogative is to select the "legally correct" opinion. The sole tool at the Court's disposal is precise and logical thinking, aided by principles set by the U.S. Supreme Court for the evaluation of scientific evidence, and adopted by the Israeli Court. The choice of the "correct" opinion centers on it's objectivity. A court-appointed expert is not necessarily an effective solution. Remuneration of the expert by the interested party increases the level of mistrust. The difficult questions concerning the credibility of an opinion arise as the result of insufficient specific expertise of the witness, presentation by a pretender to expertise or plain misrepresentation of data, excerpts of literature etc. Such transgressions are best exposed by the opposing party's expert and attorney. The court has effective means for the control of such behavior. The fraudulent expert witness is neither immune to criminal prosecution, nor to civil suit. IMA's Code of Ethics for Experts is adequate. Expert's fees should be consistent with the effort involved, as well as with the expert's rank and experience. Any linkage of fees to the outcome of the procedure should be prohibited, as well as the intervention of "contractors". Attempts to limit experts' fees, may result in the abstention of the most knowledgeable specialists from such duties. The blame for a false opinion does not lie with the paying party, it is mostly the witness who is responsible. PMID:17803167

  13. Expert system development (ESD) shell

    International Nuclear Information System (INIS)

    An Expert System Development (ESD) Shell design implementation is desribed in detail. The shell provides high-level generic facilities for Knowledge Representation (KR) and inferencing and tools for developing user interfaces. Powerful set of tools in the shell relieves much of the programming burden in the ES development. The shell is written in PROLOG under IBM PC/AT. KR facilities are based on two very powerful formalisms namely, frames and rules. Inference Engine (IE) draws most of its power from unification and backward reasoning strategy in PROLOG. This basic mechanism is enhanced further by incorporating both forward and backward chaining of rules and frame-based inferencing. Overall programming style integrates multiple paradigms including logic, object oriented, access-oriented and imperative programming. This permits ES designer a lot of flexibility in organizing inference control. Creation and maintainance of knowledge base is a major activity. The shell, therefore, provides number of facilities to simplify these tasks. Shell design also takes note of the fact that final success of any system depends on end-user satisfaction and hence provides features to build use-friendly interfaces. The shell also provides a set of interfacing predicates so that it can be embedded within any PROLOG program to incorporate functionalilty of the shell in the user program.

    An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists met on 15 January 2014 to review current evidence on the management of hilar cholangiocarcinoma in order to establish practice guidelines and to agree consensus statements. It was established that the treatment of patients with hilar cholangiocarcinoma requires a coordinated, multidisciplinary approach to optimize the chances for both durable survival and effective palliation. An adequate diagnostic and staging work-up includes high-quality cross-sectional imaging; however, pathologic confirmation is not required prior to resection or initiation of a liver transplant trimodal treatment protocol. The ideal treatment for suitable patients with resectable hilar malignancy is resection of the intra- and extrahepatic bile ducts, as well as resection of the involved ipsilateral liver. Preoperative biliary drainage is best achieved with percutaneous transhepatic approaches and may be indicated for patients with cholangitis, malnutrition or hepatic insufficiency. Portal vein embolization is a safe and effective strategy for increasing the future liver remnant (FLR) and is particularly useful for patients with an FLR of biliary cancers. PMID:26172136

    Although the need for effective long-term follow-up for patients with celiac disease (CD) has been recognized by many expert groups, published practice guidelines have not provided a clear approach for the optimal management of these patients. In an attempt to provide a thoughtful and practical approach for managing these patients, a group of experts in pediatric CD performed a critical review of the available literature in 6 categories associated with CD to develop a set of best practices by using evidence-based data and expert opinion. The 6 categories included the following: bone health, hematologic issues, endocrine problems, liver disease, nutritional issues, and testing. Evidence was assessed by using standardized criteria for evaluating the quality of the data, grade of evidence, and strength of conclusions. Over 600 publications were reviewed, and 172 were chosen for inclusion. The thorough review of the results demonstrated that the quality of the data available was often insufficient to provide unequivocal best practices. However, using the available data and the clinical experience of the panel, a practical framework for the management of children with CD was created. These recommendations were developed by our expert panel and do not necessarily reflect the policy of the American Academy of Pediatrics. The potential usefulness of these best practices is underscored by the fact that consensus, measured by the outcome of anonymous voting, was reached by the panel for 24 of the 25 questions. We hope that these best practices may be useful to the pediatric gastroenterology and larger general pediatric communities. PMID:27565547

    2008-01-01

    Whole-genome radiation hybrid (RH) mapping has proven to be a powerful tool for mapping genes and comparing genome architecture. We describe a protocol for constructing RH panels by rescuing irradiated fibroblast donor cells of any mammalian species by polyethylene glycol fusion to a thymidine kinase-deficient hamster cell line. Characterization and expansion of a panel of 90-100 cell lines can be used to map virtually any PCR-based marker that can be distinguished from the recipient hamster genome. The described procedure has been used successfully to create RH panels from diverse mammalian species such as macaques, elephants, alpacas, and armadillos, and may be applicable to nonmammalian vertebrates as well.

  20. A law for nuclear experts only

    International Nuclear Information System (INIS)

    The Federal Ministry of the Interior is preparing an ordinance on expert consultants under the Atomic Energy Act which, among other topics, is to include legal norms for the criteria to be met by experts in terms of non-partisanship, training, capabilities, technical equipment and cooperation in expert organizations of members of various scientific and technical disciplines. A summary of general criteria relating to the qualification, selection and status of experts called in by the legislative and executive branches and by courts of law, which could be organized as a series of guidelines without any original qualities of legal norms, could be recommended in view of the increasing quantitative and qualitative importance of experts. However, passing an ordinance merely fixing and putting into concrete terms the image of an 'expert under the Atomic Energy Act' is intolerable, because the status of scientific and technical experts by far extends beyond the field of nuclear law in our industrial society characterized by a far reaching division of labor. Weak points in the organization of expert services are not confined to technology or nuclear power. Separate rules establishing legal norms are not convincing also for reasons of technology policy and legal policy as well as for those of social psychology and practice. (orig.) 891 HP/orig. 892 MKO

  1. Expert system technology for the military

    International Nuclear Information System (INIS)

    This paper is concerned with the applications of expert systems to complex military problems. A brief description of needs for expert systems in the military arena is given. A short tutorial on some of the elements of an expert system is found in Appendix I. An important aspect of expert systems concerns using uncertain information and ill-defined procedures. Many of the general techniques of dealing with uncertainty are described in Appendix II. These techniques include Bayesian certainty factors, Dempster-Shafer theory of uncertainty, and Zadeh's fuzzy set theory. The major portion of the paper addresses specific expert system examples such as resource allocation, identification of radar images, maintenance and troubleshooting of electronic equipment, and the interpretation and understanding of radar images. Extensions of expert systems to incorporate learning are examined in the context of military intelligence to determine the disposition, location, and intention of the adversary. The final application involves the use of distributed communicating cooperating expert systems for battle management. Finally, the future of expert systems and their evolving capabilities are discussed

    2014-08-01

    Full Text Available The aim of this study was to examine the information acquisition strategies of expert and competent non-expert intensive care physicians during two simulated diagnostic scenarios involving respiratory distress in an infant. Specifically, the information acquisition performance of six experts and 12 competent non-experts was examined using an eye tracker during the initial 90 seconds of the assessment of the patient. The results indicated that, in comparison to competent non-experts, experts recorded longer mean fixations, irrespective of the scenario. When the dwell times were examined against specific areas of interest, the results revealed that competent non-experts recorded greater overall dwell times on the nurse, where experts recorded relatively greater dwell times on the head and face of the manikin. In the context of the scenarios, experts recorded differential dwell times, spending relatively more time on the head and face during the seizure scenario than during the coughing scenario. The differences evident between experts and competent non-experts were interpreted as evidence of the relative availability of task-specific cues or heuristics in memory that might direct the process of information acquisition amongst expert physicians. The implications are discussed for the training and assessment of diagnostic skills.

    1988-01-01

    Expert Missile Maintenance Aid (EMMA) is a first attempt to enhance maintenance of the tactical munition at the field and depot level by using artificial intelligence (AI) techniques. The ultimate goal of EMMA is to help a novice maintenance technician isolate and diagnose electronic, electromechanical, and mechanical equipment faults to the board/chassis level more quickly and consistently than the best human expert using the best currently available automatic test equipment (ATE). To this end, EMMA augments existing ATE with an expert system that captures the knowledge of design and maintenance experts. The EMMA program is described, including the evaluation of field-level expert system prototypes, the description of several study tasks performed during EMMA, and future plans for a follow-on program. This paper will briefly address several study tasks performed during EMMA. The paper concludes with a discussion of future plans for a follow-on program and other areas of concern.

  15. Marine Oil Spill Expert Systems (MOSES)

    International Nuclear Information System (INIS)

    The marine oil response community is international by nature. With two-thirds of the world's oil supply crossing oceans, a spill could occur anywhere at any time. Advances in information technology make it possible to retrieve information instantaneously. The information is critical in formulating a response operation. Computers are an indispensable tool on location. They can operate off-site, with information being sent from the spill site to the place where the computer is located. Expert systems are an excellent means to capture and store knowledge on the computer for rapid retrieval when needed. They are very useful in cases where timing is critical and decision-making is complex. Expert systems can be a cost-effective response tool, but it was suggested that in order to take greater advantage of this tool, more effort should be devoted to improving the decision-making of expert systems to marine oil spill response operations. The authors pointed out that expert systems will never replace human judgement, but with the current generation of response experts nearing retirement, it is important to preserve the bank of knowledge acquired by these experts. The lessons learned by these experts can be transferred to the computer for easy access, retrieval and application during a spill event. 6 refs

  16. Sherlock Holmes: an expert's view of expertise.

    Science.gov (United States)

    André, Didierjean; Fernand, Gobet

    2008-02-01

    In recent years, there has been an intense research effort to understand the cognitive processes and structures underlying expert behaviour. Work in different fields, including scientific domains, sports, games and mnemonics, has shown that there are vast differences in perceptual abilities between experts and novices, and that these differences may underpin other cognitive differences in learning, memory and problem solving. In this article, we evaluate the progress made in the last years through the eyes of an outstanding, albeit fictional, expert: Sherlock Holmes. We first use the Sherlock Holmes character to illustrate expert processes as described by current research and theories. In particular, the role of perception, as well as the nature and influence of expert knowledge, are all present in the description of Conan Doyle's hero. In the second part of the article, we discuss a number of issues that current research on expertise has barely addressed. These gaps include, for example, several forms of reasoning, the influence of emotions on cognition, and the effect of age on experts' knowledge and cognitive processes. Thus, although nearly 120-year-old, Conan Doyle's books show remarkable illustrations of expert behaviour, including the coverage of themes that have mostly been overlooked by current research.

    Hays, Ron D; Liu, Honghu; Kapteyn, Arie

    2015-09-01

    The use of Internet panels to collect survey data is increasing because it is cost-effective, enables access to large and diverse samples quickly, takes less time than traditional methods to obtain data for analysis, and the standardization of the data collection process makes studies easy to replicate. A variety of probability-based panels have been created, including Telepanel/CentERpanel, Knowledge Networks (now GFK KnowledgePanel), the American Life Panel, the Longitudinal Internet Studies for the Social Sciences panel, and the Understanding America Study panel. Despite the advantage of having a known denominator (sampling frame), the probability-based Internet panels often have low recruitment participation rates, and some have argued that there is little practical difference between opting out of a probability sample and opting into a nonprobability (convenience) Internet panel. This article provides an overview of both probability-based and convenience panels, discussing potential benefits and cautions for each method, and summarizing the approaches used to weight panel respondents in order to better represent the underlying population. Challenges of using Internet panel data are discussed, including false answers, careless responses, giving the same answer repeatedly, getting multiple surveys from the same respondent, and panelists being members of multiple panels. More is to be learned about Internet panels generally and about Web-based data collection, as well as how to evaluate data collected using mobile devices and social-media platforms. PMID:26170052

    Lawley, Russell; Barron, Mark; Lee, Katy

    2014-05-01

    elicitation is to extract this model in a useable, quantitative, form by a robust and transparent procedure. At BGS expert elicitation is being used to evaluate the uncertainty of mapped boundaries in different common mapping scenarios, with a view to building a 'collective' understanding of the challenges each scenario presents. For example, a 'sharp contact (at surface) between highly contrasting sedimentary rocks' represents one level of survey challenge that should be accurately met by all surveyors, even novices. In contrast, a 'transitional boundary defined by localised facies-variation' may require much more experience to resolve (without recourse to significantly more sampling). We will describe the initial phase of this exercise in which uncertainty models were elicited for mapped boundaries in six contrasting scenarios. Each scenario was presented to a panel of experts with varied expertise and career history. In five cases it was possible to arrive at a consensus model, in a sixth case experts with different experience took different views of the nature of the mapping problem. We will discuss our experience of the use of elicitation methodology and the implications of our results for further work at the BGS to quantify uncertainty in map products. In particular we will consider the value of elicitation as a means to capture the expertise of individuals as they retire, and as the composition of the organization's staff changes in response to the management and policy decisions.

    International Nuclear Information System (INIS)

    Within the process of renewal of Exploitation Permit of Jose Cabrera Nuclear Power Plant, UNION FENOSA GENERACIO, S. A. (UFG) has carried out an analysis and evaluation project regarding human factors implications of current control room panel arrangement. The project has been developed in two phases. In the first phase, leaded by EPRI and carried out by experts from SAIC, an independent review from a double viewpoint of human reliability and human factors was developed. In the second phase, a multidisciplinary team (composed by human factors, risk analysis, operation, engineering, training and instrumentation and controls experts) has developed a study on human factors implications of current panel arrangement, following the methodology pointed out in NUREG-0711. The project has been developed under the direction of Brookhaven National Laboratory (BNL), organisation that has authored the aforementioned methodology, with the participation of UFG and SOLUZIONA Ingenieria. For the development of the second study the following steps were taken: Firstly, the potential effects of panel arrangement on crew performance were identified its real evidence was analysed and the goals for the improvement of control room operation were established; following NUREG-0711. After this, several design alternatives that addressed these goals were identified and were analysed along three dimensions: human factors, risk analysis and economic costs. Finally the results of these evaluations were combined using a multi-attribute decision method to arrive at a recommended alternative as he best proposal to incorporate human factors criteria and good practices in the design of control room panels.

  3. An expert system for turbogenerator diagnostics

    International Nuclear Information System (INIS)

    In 1990, an expert system for turbo-generator diagnostics (EST-D) was installed at the 3rd and 4th units of the Paks NPP (Hungary). The expert system is strongly integrated to the ARGUS II vibration monitoring and diagnostics system. The system works on IBM PC AT. The VEIKI's and the NPP's human experts were interviewed to fill up the knowledgebase. The system is able to identify 13 different faults of the parts of a turbogenerator. The knowledgebase consists of ca 200 rules. The rules were built in and the system was verified and validated using a model of the turbines and using the experiences gathered with ARGUS II during the last 3 years. The maintenance personnel is authorized to modify and/or extend the knowledgebase. The input data for evaluation come from measured vibration patterns produced by the ARGUS II system, database of events, and maintenance data input by the maintenance personnel. The expert system is based on the modified GENESYS 2.1 shell (developed by SZAMALK, Hungary). Some limitations from PC application were eliminated, and a new, independent explanation module and man-machine interface were developed. Using this man-machine interface, one of the basic goals of the expert system developments was achieved: the human experts contribution is not necessary for diagnoses. The operator of the diagnostics system is able to produce the reports of diagnoses. Of course the interface allows the human experts to see the diagnoses through. It should be mentioned, at the beginning of 1991, we installed a similar expert system at the 1st 1000 MW WWER type unit of the Kalinin NPP (Soviet Union). In this paper, the operation of the EST-D, the man-machine interface and the operational experiences of the first 4 months work are explained. 2 refs., 14 figs

    In previous research it has been shown that link-based web page metrics can be used to predict experts' assessment of quality. We are interested in a related question: do expert rankings of real-world entities correlate with search engine rankings of corresponding web resources? For example, each year US News & World Report publishes a list of (among others) top 50 graduate business schools. Does their expert ranking correlate with the search engine ranking of the URLs of those business schools? To answer this question we conducted 9 experiments using 8 expert rankings on a range of academic, athletic, financial and popular culture topics. We compared the expert rankings with the rankings in Google, Live Search (formerly MSN) and Yahoo (with list lengths of 10, 25, and 50). In 57 search engine vs. expert comparisons, only 1 strong and 4 moderate correlations were statistically significant. In 42 inter-search engine comparisons, only 2 strong and 4 moderate correlations were statistically significant. The ...

  10. Reforming emergency care: Experts put focus on value, better alignment.

    Science.gov (United States)

    2015-07-01

    While most healthcare reforms have thus far been focused outside of the ED, they nonetheless have big implications for emergency providers, according to a panel of experts who discussed the future of emergency care at a conference sponsored by the Brookings Institution in Washington, DC. Going forward, the experts noted that emergency providers need to engage on how to most-effectively deliver higher value while also achieving better alignment with primary care providers. And they highlighted reforms that are already delivering results in pioneering EDs. Through the use of high-risk care plans, a specialized protocol for chest pain, and other reforms, the ED at the University of Maryland Upper Chesapeake Health System, based in Bel Air, MD, has been able to prevent more than 500 hospital admissions in the past year. Working with partners, emergency physicians in Washington state have managed to save the state more than $32 million while also slashing narcotic prescribing to Medicaid recipients by 24%. Their interventions include a prescription drug monitoring program, a mechanism for information sharing on key data points, and the development of care plans for frequent ED utilizers. A program called Bridges to Care in Denver, CO, has thus far been able to reduce ED and hospital utilization among frequent utilizers by 40%, generating $2 million in cost-savings to the health care system. The program focuses on identifying the key drivers of utilization, and then addressing these drivers with interventions. Program developers say connecting with patients while they are still in the ED, as opposed to making follow-up phone calls, is key to the program's success. PMID:26131537

  11. Childhood obesity: highlights of AMA Expert Committee recommendations.

    Science.gov (United States)

    Rao, Goutham

    2008-07-01

    Childhood obesity is an increasingly serious problem; 13.9 percent of children two to five years of age, 18.8 percent of children six to 11 years of age, and 17.4 percent of adolescents 12 to 19 years of age in America are obese. Practical strategies that primary care physicians can use to tackle the problem are scarce. The American Medical Association recently convened an expert panel to address this need. Evidence about how best to manage and prevent obesity was reviewed and incorporated into a series of reports. The Expert Committee on the Assessment, Prevention, and Treatment of Child and Adolescent Overweight and Obesity recommends addressing the issue of weight with all children at least once a year. Family physicians are urged to assess key dietary habits (e.g., consumption of sweetened beverages), physical activity habits, readiness to change lifestyle habits, and family history of obesity and obesity-related illnesses. Laboratory testing recommendations depend on the degree of obesity and associated illnesses. For children with a body mass index between the 85th and 94th percentiles but who have no obesity-related illnesses, a fasting lipid profile should be done. Those with the same body mass index and obesity-related illnesses should also have tests for alanine transaminase, aspartate transaminase, and fasting blood glucose levels. Measurement of blood urea nitrogen and creatinine levels should be added in children with a body mass index above the 95th percentile. A four-stage approach to treatment of childhood obesity is recommended. Many of these recommendations can be carried out by family physicians for treatment and prevention. These include advising families to limit consumption of sweetened beverages and fast food, limit screen time, engage in physical activity for at least 60 minutes per day, and encourage family meals on most, and preferably all, days of the week.

    Cunningham-Burley Sarah

    2009-04-01

    Full Text Available Abstract Background Smoking in the home is the major cause of exposure to second-hand smoke in children in the UK, particularly those living in low income households which have fewer restrictions on smoking in the home. Reducing children's exposure to second-hand smoke is an important public health and inequalities issue. Drawing on findings from a qualitative Scottish study, this paper identifies key issues and challenges that need to be considered when developing action to promote smoke-free homes at the national and local level. Methods Two panels of tobacco control experts (local and national from Scotland considered the implications of the findings from a qualitative study of smokers and non-smokers (who were interviewed about smoking in the home, for future action on reducing smoking in the home. Results Several key themes emerged through the expert panel discussions. These related to: improving knowledge about SHS among carers and professionals; the goal and approach of future interventions (incremental/harm reduction or total restrictions; the complexity of the interventions; and issues around protecting children. Conclusion The expert panels were very aware of the sensitivities around the boundary between the 'private' home and public health interventions; but also the lack of evidence on the relative effectiveness of specific individual and community approaches on increasing restrictions on smoking in the home. Future action on smoke-free homes needs to consider and address these complexities. In particular health professionals and other key stakeholders need appropriate training on the issues around smoking in the home and how to address these, as well as for more research to evaluate interventions and develop a more robust evidence base to inform effective action on this issue.

  14. Enhancing Transparency in Multidisciplinary Expert Communication

    International Nuclear Information System (INIS)

    Faced with problems of public acceptance most nuclear waste management organisations now acknowledge the importance of transparency in their pursuit of solutions for high-level nuclear waste disposal. To make progress the implementing organizations need the trust of other stakeholders in the decision-making process. For such trust these outside stakeholders need knowledge on the grounds for the judgments and decisions made in different scientific and technical disciplines. Transparency is, however, at least as important for the multidisciplinary expert communication itself. As a matter of fact, the transparency of the internal expert interaction processes is a prerequisite for the true transparency of the communication between the implementer and the external stakeholder groups. The introduced conceptual framework has been developed for the identification of the requirements of safety-informed communication in multidisciplinary expert work in nuclear waste management. The framework offers a common thinking model and common concepts which can be utilized in the development of the communication practices. The basis of the framework is on the possibility to understand the safety-critical significance of one's work. The transparency of communication is, for its part, based on making explicit the relevant knowledge necessary for gaining the understanding. This supplementary knowledge, which is related to the substance issues but is not scientific-technical by nature, enhances the experts' awareness of the context of their own contribution and of the background of the other experts' contributions. The common conceptualization and modelling of the knowledge-related dependencies between the tasks make it possible to realize the significance of the supplementary knowledge for transparent communication in actual situations. They also facilitate the recognition of the need for different types of supplementary knowledge in the interfaces between the tasks. By enhancing mutual

    2016-08-01

    The experiment aimed at defining a grading scheme for Italian Simmental (IS) beef linked to objective measure of eating quality. Four experts developed a meat quality grid based on the assessment of the steak between the 8th and 9th ribs (reference steak). The grid was tested on the reference steak of 29 IS young-bulls. Rib-eye dimension, meat colour, marbling, meat firmness and fat cover highly contributed to overall quality. Two classes of IS beef quality were identified: standard and high. The results were associated with the sensory profile of Longissimus thoracis muscle from the reference steaks performed by a trained panel. The differences in quality highlighted by experts in raw steak accounted for most of the relevant information regarding the sensory properties of cooked beef. The accuracy of predictive model was 96.6%. The developed scheme is a helpful tool for valuing the eating quality of beef. PMID:26998946

  16. Analytical comparison of three stiffened panel concepts

    Maloney, Jill M.; Wu, K. Chauncey; Robinson, James C.

    1995-01-01

    Three stiffened panel concepts are evaluated to find optimized designs for integral stiffeners in the barrels of Reusable Launch Vehicle fuel tanks. The three panel concepts considered are a T-stiffened panel, a panel with one blade stiffener centered between each pair of T-stiffeners, and a panel with two blade stiffeners equally spaced between each pair of T-stiffeners. The panels are optimized using PASCO for a range of compressive loads, and the computed areal weight for each panel is used to compare the concepts and predict tank weights. The areal weight of the T-stiffened panel with one blade is up to seven-percent lower than the other panel concepts. Two tank construction methods are compared for a representative tank design with three barrels. In the first method, 45-degree circumferential sections of a barrel are each designed to carry the same maximum load in the barrel. In the second method, each barrel section is designed for the maximum load in that section. Representative tanks designed with the first method are over 250 lb heavier than tanks designed using the second method. Optimized panel designs and areal weights are also computed for variation of the nominal panel length and skin thickness.

    This is an expert consensus on the evaluation and treatment of thoracolumbar spinal injury, estab-lished from February 2009 to July 2010. The expert consensus consists mainly of six parts with a total of 54 recommendations including the overview (one item);pre-hospital care (one item);evalu-ation and diagnosis (13 items);treatment (23 items); prevention and treatment of major complica-tions (12 items);and rehabilitation (four items). This is the first time that Chinese experts have pub-lished a consensus on spine and spinal cord injury. The expert consensus was established based on Delphi methods, literature analysis, and clinical experiences. Each recommendation is supported by and was interpreted using multi-level evidences. The level of agreement with the recommenda-tion among the panel members was assessed as either low, moderate, or strong. Each panel member was asked to indicate his or her level of agreement on a 5-point scale, with “1” corre-sponding to neutrality and“5”representing maximum agreement. Scores were aggregated across the panel members and an arithmetic mean was calculated. This mean score was then translated into low, moderate, or strong. After al of the votes were col ected and calculated, the results showed no low-level recommendations, 10 moderate-level recommendations, and 44 strong-level recom-mendations. An expert consensus was reached and was recognized by Chinese spine surgeons. Wide-scale adoption of these recommendations is urgent in the management of acute thoracol-umbar spine and spinal cord injury in a broader attempt to create a standard evaluation and treat-ment strategy for acute thoracolumbar spine and spinal cord injury in China.

    2016-08-01

    Because human-computer interactions are increasingly important, touch panels may require stretchability and biocompatibility in order to allow integration with the human body. However, most touch panels have been developed based on stiff and brittle electrodes. We demonstrate an ionic touch panel based on a polyacrylamide hydrogel containing lithium chloride salts. The panel is soft and stretchable, so it can sustain a large deformation. The panel can freely transmit light information because the hydrogel is transparent, with 98% transmittance for visible light. A surface-capacitive touch system was adopted to sense a touched position. The panel can be operated under more than 1000% areal strain without sacrificing its functionalities. Epidermal touch panel use on skin was demonstrated by writing words, playing a piano, and playing games.

All of the evaluations by the panel were based upon the use of the fluidized bed unit proposed by Rocky Flats and cannot be generalized to other systems

  20. Use of expert systems in nuclear safety

    International Nuclear Information System (INIS)

    One dominant aspect of improvement in safe nuclear power plant operation is the very high speed in the development and introduction of computer technologies. This development commenced recently when advanced control technology was incorporated into the nuclear industry. This led to an increasing implementation of information displays, annunciator windows and other devices inside the control room, eventually overburdening the control room operator with detailed information. Expert systems are a further step in this direction being designed to apply large knowledge bases to solve practical problems. These ''intelligent'' systems have to incorporate enough knowledge to reach expert levels of importance and represent a very advanced man-machine interface. The aims of the Technical Committee were addressed by the three Working Groups and summarized in Sections 2, 3 and 4 of this report. Section 2 summarizes the results and discussions on the current capabilities of expert systems and identifies features for the future development and use of Expert Systems in Nuclear Power Plants. Section 3 provides an overview of the discussions and investigations into the current status of Expert Systems in NPPs.

    battery of tests covering a larger range of auditory capabilities in order to assess individual listeners. The format of all tests is kept as 'objective' as possible by using a three-alternative forced-choice paradigm in which the subject must choose which of the sound samples is different, thus keeping...... the instruction to the subjects simple and common for all tests. Both basic (e.g. frequency discrimination) and complex (e.g. profile analysis) psychoacoustic tests are covered in the battery and a threshold of discrimination or detection is obtained for each test. Data were collected on 24 listeners...... who had been recruited for participation in an expert listening panel for evaluating the sound quality of hi-fi audio systems. The test battery data were related to the actual performance of the listeners when judging the degradation in quality produced by audio codecs....

    2011-01-01

    Full Text Available The Extensible Markup Language (XML is a subset of SGML that is completely described in this paper. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML. An expert system is a computer program designed to simulate the problem-solving behavior of a human who is an expert in a narrow domain or discipline. Expert Systems (ES, also called Knowledge Based System (KBS, are computer application programs that take the knowledge of one or more human experts in a field and computerize it so that it is readily available for use. The main objective of this paper was to investigate the usage of different refinement methodologies for different layers of knowledge base modeling and investigate the possibility of building an expert system development and refinement tool. In our work we used XML as a knowledge representation to represent the knowledge base. Therefore we used the mathematical model to refinement of a knowledge base.

  6. Assessment of the cortisol awakening response: Expert consensus guidelines.

    The cortisol awakening response (CAR), the marked increase in cortisol secretion over the first 30-45 min after morning awakening, has been related to a wide range of psychosocial, physical and mental health parameters, making it a key variable for psychoneuroendocrinological research. The CAR is typically assessed from self-collection of saliva samples within the domestic setting. While this confers ecological validity, it lacks direct researcher oversight which can be problematic as the validity of CAR measurement critically relies on participants closely following a timed sampling schedule, beginning with the moment of awakening. Researchers assessing the CAR thus need to take important steps to maximize and monitor saliva sampling accuracy as well as consider a range of other relevant methodological factors. To promote best practice of future research in this field, the International Society of Psychoneuroendocrinology initiated an expert panel charged with (i) summarizing relevant evidence and collective experience on methodological factors affecting CAR assessment and (ii) formulating clear consensus guidelines for future research. The present report summarizes the results of this undertaking. Consensus guidelines are presented on central aspects of CAR assessment, including objective control of sampling accuracy/adherence, participant instructions, covariate accounting, sampling protocols, quantification strategies as well as reporting and interpreting of CAR data. Meeting these methodological standards in future research will create more powerful research designs, thus yielding more reliable and reproducible results and helping to further advance understanding in this evolving field of research.

    The composite panel with photovoltaic-thermo module becomes higher in energy-saving than the conventional air-conditioning system by the independent radiational heating and cooling effect obtained when the generating panel using a solar cell module is combined with the heating and cooling panel using a thermo-element module. The output of a solar cell module can be directly used because the solar cell module operates in AC. This paper reports the relation between the absorbed value and power consumption of the cooling panel, while paying attention to the cooling panel. The performance coefficient of the maximum absorbed value from an non-absorbing substance to a cooling panel is 2 to 3. Assume that the cooling panel during non-adiabatic operation is operated using a solar cell module of 800 W/m{sup 2} in solar intensity and 15% in conversion efficiency. The cooling-surface temperature difference is 12.12 K, and the maximum absorbed value of a non-absorbing substance to a cooling panel is 39.12 W/m{sup 2}. The absorbed value of the outer temperature to the cooling panel is 74.4 W/m{sup 2}, and each performance coefficient is 3.26 and 0.62. The absorbed value must be calculated for evaluation from the cooling-surface temperature difference measured directly from the cooling panel. 4 refs., 8 figs., 1 tab.

    Piezocomposite SmartPanelsTM, consisting of 1-3 actuators and pressure sensors and net-shape-molded PZT accelerometers in a large area low profile panel, have been fabricated at Materials Systems Inc. and evaluated at the Naval Research Laboratory. Single layer and two-layer 100 X 100 mm SmartPanels have been tested for sensor sensitivities, actuator authority, surface displacement uniformity, and sensor-actuator coupling. Multilayer GRP circuits boards are used both as stiff faceplates and to provide electrical connections and ground planes. The SmartPanel technology has recently been scaled up to 250 X 250 mm devices. SmartPanels draw upon PZT (lead zirconate titanate) ceramic injection molding technology, which is used to produce cost-effective and robust 1-3 piezoelectric ceramic-polymer composite materials. The 1-3 materials are used extensively for SonoPanelTM transducers in a number of sensor and actuator applications. SonoPanels have been qualified for US Navy applications, based on successful completion of pressure and shock tests, and are currently being scaled up from 250 X 250 mm to 750 X 750 mm panels. Several applications for SmartPanels and SonoPanels are described, including conformable transducers, multielement arrays, pressure sensors, and velocity sensors.

  9. Microclimate boxes for panel paintings

    DEFF Research Database (Denmark)

    Wadum, Jørgen

    The use of microclimate boxes to protect vulnerable panel paintings is, therefore, not a new phenomenon of the past two or three decades. Rather, it has been a concern for conservators and curators to protect these objects of art at home and in transit since the end of the nineteenth century. The...... increased number of travelling exhibitions in recent years has heightened the need to protect paintings during circulation (Thomson 1961; Mecklenburg 1991). The use and design of microclimate boxes have been evolving since 1892. These boxes may be divided into three broad groups: those using an active...

    The light trapping device (LTD) was theoretically designed to suggests the best way of harvesting the energy derived from natural lightning. The Maxwell's equation was expanded using a virtual experimentation via a MATLAB environment. Several parameters like lightning flash and temperature distribution were consider to investigate the ability of the theoretical lightning panel to convert electricity efficiently. The results of the lighting strike angle on the surface of the LTD shows the maximum power expected per time. The results of the microscopic thermal distribution shows that if the LTD casing controls the transmission of the heat energy, then the thermal energy storage (TES) can be introduced to the lightning farm.

  13. Expert system aided operator's mental activities training

    International Nuclear Information System (INIS)

    The operator's mental activity is the most important part of his work. A processing of a large amount of the information by the operator is possible only if he/she possesses appropriate cognitive skills. To facilitate the novice's acquisition of the experienced operator's cognitive skills of the decision-making process a special type of the expert system was developed. The cognitive engineering's models and problem-solving methodology constitutes the basis of this expert system. The article gives an account of the prototype of the mentioned expert system developed to aid the whole mental activity of the nuclear power plant operator during his decision-making process.

    Being a surgical expert witness (EW) in professional liability claims implies ethical responsibilities, which are usually unknown to the parties who try to obtain such testimony as well as to the surgeons involved in providing the expert opinion required by the courts. Giving medical testimony can be included in the field of surgery since (1) being an expert medical witness and judge the performance of another surgeon means that the witness must have a medical license and preferably be board-certified as a surgeon, and (2) the EW opinion sets the standard of care to be applied in each particular case. Thus, the role of the surgeon EW in the legal arena must have the same degree of integrity as the surgeon in his practice with direct patient care and it should be reviewed and subject to regulation.

  16. Recruiting experts for technical assistance rogramme

    International Nuclear Information System (INIS)

    One of the objectives of the IAEA is the provision of technical assistance to its Member States to carry out their peaceful nuclear activities more efficiently and safely. This involves looking for and supplying experts, equipment and fellowships. Since 1958 the Agency has provided the services of more than 1800 experts valued at $11.5 million, 4300 fellowships valued at $14.3 million, and equipment worth $10.8 million. The efficiency of the programme can only be increased by a more prompt consideration of proposals forwarded by the Agency, and the continuing co-operation from national Governments and private institutions. The IAEA recruits an average of 200 experts a year to implement its Regular Technical Assistance Programme. These projects are financed by voluntary contributions from Member States, and by the United Nations Development Programme for those projects for which the IAEA is the executing agency

  17. How expert advice influences decision making.

    2012-01-01

    People often use expert advice when making decisions in our society, but how we are influenced by this advice has yet to be understood. To address this, using functional magnetic resonance imaging, we provided expert and novice advice to participants during an estimation task. Participants reported that they valued expert advice more than novice advice, and activity in the ventral striatum correlated with this valuation, even before decisions with the advice were made. When using advice, participants compared their initial opinion to their advisor's opinion. This comparison, termed the "opinion difference", influenced advice utilization and was represented in reward-sensitive brain regions. Finally, the left lateral orbitofrontal cortex integrated both the size of the opinion difference and the advisor's level of expertise, and average activity in this area correlated with mean advice utilization across participants. Taken together, these findings provide neural evidence for how advice engenders behavioral change during the decision-making process. PMID:23185425

    2010-01-01

    We apply the method of defensive forecasting, based on the use of game-theoretic supermartingales, to prediction with expert advice. In the traditional setting of a countable number of experts and a finite number of outcomes, the Defensive Forecasting Algorithm is very close to the well-known Aggregating Algorithm. Not only the performance guarantees but also the predictions are the same for these two methods of fundamentally different nature. We discuss also a new setting where the experts can give advice conditional on the learner's future decision. Both the algorithms can be adapted to the new setting and give the same performance guarantees as in the traditional setting. Finally, we outline an application of defensive forecasting to a setting with several loss functions.

  19. An expert system in medical diagnosis

    International Nuclear Information System (INIS)

    Health problem is still a crucial one in some countries. It is so important that it becomes a major handicap in economic and social development. In order to solve this problem, we have conceived an expert system that we called MITSABO, which means TO HEAL, to help the physicians to diagnose tropical diseases. It is clear that by extending the data base and the knowledge base, we can extend the application of the software to more general areas. In our expert system, we used the concept of 'self organization' of neural network based on the determination of the eigenvalues and the eigenvectors associated to the correlation matrix XXt. The projection of the data on the two first eigenvectors gives a classification of the diseases which is used to get a first approach in the diagnosis of the patient. This diagnosis is improved by using an expert system which is built from the knowledge base.

  20. Boosting as a Product of Experts

    CERN Document Server

    Edakunni, Narayanan U; Kovacs, Tim

    2012-01-01

    In this paper, we derive a novel probabilistic model of boosting as a Product of Experts. We re-derive the boosting algorithm as a greedy incremental model selection procedure which ensures that addition of new experts to the ensemble does not decrease the likelihood of the data. These learning rules lead to a generic boosting algorithm - POE- Boost which turns out to be similar to the AdaBoost algorithm under certain assumptions on the expert probabilities. The paper then extends the POEBoost algorithm to POEBoost.CS which handles hypothesis that produce probabilistic predictions. This new algorithm is shown to have better generalization performance compared to other state of the art algorithms.

  1. An expert system for diesel generator diagnostics

    International Nuclear Information System (INIS)

    The idea of developing artificial intelligence (AI) systems to capture the knowledge of human experts is receiving much attention these days. The idea is even more attractive when important expertise resides within a single individual, especially one who is nearing retirement and who has not otherwise recorded or passed along his important knowledge and thought processes. The diesel generators at Pilgrim Nuclear Power Station have performed exceptionally well, primarily due to the care and attention of one man. Therefore, the authors are constructing an expert system for the diagnosis of diesel generator problems at Pilgrim. This paper includes a description of the expert system design and operation, examples from the knowledge base, and sample diagnoses, so the reader can observe the process in action

  4. Biophysical aspects of radiation quality. Report of a panel

    International Nuclear Information System (INIS)

    In radiation biology it is essential to understand the different effectiveness, or radiation quality, of various kinds of ionizing radiations on living systems. Research work on this subject has only been done fairly recently; it includes the experimental determination of local energy absorption in tissue (microdosimetry), investigations of physical and chemical factors modifying radiation effect, and theoretical interpretations of dose effect relationships. This work is not only of high academic interest but is also very important for the evaluation of radiation hazards in mixed radiation fields, near high-energy particles, and in space. A Panel of experts was convened from 29 March to 2 April, 1965, in Vienna at the Headquarters of the International Atomic Energy Agency under the chairmanship of Professor H. H. Rossi, to discuss current research on the subject. The participants were prominent biologists and biophysicists representing the most active groups working on radiation quality. At the end of the meeting it was clear that the Panel had fulfilled a most useful purpose by stimulating the exchange of ideas and improving the contacts between workers in different parts of the world, and by proposing lines of development for basic research in radiobiology

  5. Distributed expert systems for nuclear reactor control

    1987-05-01

    Optics has advantages for overcoming limitations arising when applying existing electronic technologies to real-time parallel computation. In particular, spatial light modulators (SLMs) permit simultaneous storage, multiplication, and/or complex interconnection. A simple expert uses an SLM crossbar switch to provide a flexible and fast implementation of combinatorial logic. A second expert system, illustrated using medical diagnosis, uses the Bayes theorem to update recursively the probabilities of various illnesses given additional symptom information. The a priori probability matrices are stored in SLMs which provide matrix-vector multiplication and interconnection. Computation of the best next symptom question is possible because of the high speed.

  7. Emphasizing Expert Practice with Spaced Recall

    CERN Document Server

    Torigoe, Eugene T

    2015-01-01

    This paper explores an intervention that emphasizes expert practice using spaced recall. Interviews were performed with two students who were shown physics solutions, and were asked to repeatedly recall the solutions over a period of weeks. The students reflected that they became aware of the importance of using the diagrams to create equations, as well as the utility of reasoning over pure memorization. We believe that the structure of this activity may be an effective way of encouraging expert practice to introductory physics students.

  11. Solar-Panel Dust Accumulation and Cleanings

    Science.gov (United States)

    2005-01-01

    Air-fall dust accumulates on the solar panels of NASA's Mars Exploration Rovers, reducing the amount of sunlight reaching the solar arrays. Pre-launch models predicted steady dust accumulation. However, the rovers have been blessed with occasional wind events that clear significant amounts of dust from the solar panels. This graph shows the effects of those panel-cleaning events on the amount of electricity generated by Spirit's solar panels. The horizontal scale is the number of Martian days (sols) after Spirit's Jan. 4, 2005, (Universal Time) landing on Mars. The vertical scale indicates output from the rover's solar panels as a fraction of the amount produced when the clean panels first opened. Note that the gradual declines are interrupted by occasional sharp increases, such as a dust-cleaning event on sol 420.

The objective of this program was to demonstrate the feasibility of an ECSA panel that minimizes panel surface potential below 100mV in LEO and GEO charged particle environments, prevents exposure of solar cell voltage and panel insulating surfaces to the ambient environment, and provides an equipotential, grounded structure surrounding the entire panel. An ECSA panel design was developed that uses a Front Side Aperture-Shield (FSA) that covers all inter-cell areas with a single graphite composite laminate, composite edge clips for connecting the FSA to the panel substrate, and built-in tabs that interconnect the FSA to conductive coated coverglasses using a conductive adhesive. Analysis indicated the ability of the design to meet the ECSA requirements. Qualification coupons and a 0.5m x 0.5m prototype panel were fabricated and tested for photovoltaic performance and electrical grounding before and after exposure to acoustic and thermal cycling environments. The results show the feasibility of achieving electrostatic cleanliness with a small penalty in mass, photovoltaic performance and cost, with a design is structurally robust and compatible with a wide range of current solar panel technologies.

    2015-12-01

    The purpose of the current study was to investigate the moderating or mediating role played by risk perception in decision-making, gambling behaviour, and disordered gambling aetiology. Eleven gambling expert clinicians and researchers completed a semi-structured interview derived from mental models and grounded theory methodologies. Expert interview data was used to construct a comprehensive expert mental model 'map' detailing risk-perception related factors contributing to harmful or safe gambling. Systematic overlapping processes of data gathering and analysis were used to iteratively extend, saturate, test for exception, and verify concepts and emergent themes. Findings indicated that experts considered idiosyncratic beliefs among gamblers result in overall underestimates of risk and loss, insufficient prioritization of needs, and planning and implementation of risk management strategies. Additional contextual factors influencing use of risk information (reinforcement and learning; mental states, environmental cues, ambivalence; and socio-cultural and biological variables) acted to shape risk perceptions and increase vulnerabilities to harm or disordered gambling. It was concluded that understanding the nature, extent and processes by which risk perception predisposes an individual to maintain gambling despite adverse consequences can guide the content of preventative educational responsible gambling campaigns.

  4. Being an expert witness in geomorphology

    Science.gov (United States)

    Keller, Edward A.

    2015-02-01

    Gathering your own data and coming to your own conclusion through scientific research and discovery is the most important principle to remember when being an expert witness in geomorphology. You can only be questioned in deposition and trial in your area of expertise. You are qualified as an expert by education, knowledge, and experience. You will have absolutely nothing to fear from cross-examination if you are prepared and confident about your work. Being an expert witness requires good communication skills. When you make a presentation, speak clearly and avoid jargon, especially when addressing a jury. Keep in mind that when you take on a case that may eventually go to court as a lawsuit, the entire process, with appeals and so forth, can take several years. Therefore, being an expert may become a long-term commitment of your time and energy. You may be hired by either side in a dispute, but your job is the same - determine the scientific basis of the case and explain your scientific reasoning to the lawyers, the judge, and the jury. Your work, including pre-trial investigations, often determines what the case will be based on. The use of science in the discovery part of an investigation is demonstrated from a California case involving the Ventura River, where building of a flood control levee restricted flow to a narrower channel, increasing unit stream power as well as potential for bank erosion and landsliding.

  5. Industrial disasters - the expert systems solution

    International Nuclear Information System (INIS)

    Six mistakes by the operators led to the accident at the Cherobyl nuclear reactor. These have been studied. It is suggested that an expert systems approach could prevent similar accidents. The expert system is a new approach to software programming where programs are required to perform intelligent analyses of complex situations. It separates the knowledge of a problem from the procedural code that performs the decision. An expert system will evaluate data and indicate a priority on alarms in real time. Now software systems can detect the cause of a problem in a process plant and present their findings to the operators in the control room. This should enable operators to make the correct decisions as they will know which underlying process faults are causing the alarms to operate. The Chernobyl post-mortem meeting made 13 proposals for improving safety. Two in particular are noted as relevant to expert advice systems; international collaboration on man-reactor relationships and a conference to explore the balance of automation and human action to minimise operating errors.

  8. [Expert systems and antibiotic sensitivity test].

    Flandrois, J; Carret, G

    1991-01-01

    Artificial intelligence is a part of computer science that deals with programs mimicking intelligence of man. Artificial intelligence is now used to check the quality of the determination of antibiotics susceptibility of bacteria. This application is useful because antibiotic susceptibility is subject to biological and technical variation that have to be detected. Three types of reasoning are used either by the biologist or by expert systems: low level quality checking dealing with individual results, microbiological interpretation of the whole set of results and medical interpretation of the results. The use of artificial intelligence in these fields is sustained by the structured nature of the knowledge. Two type of expert systems are already of routine use, either based on production rules (ATB plus EXPERT, bioMerieux, La Balme-les-Grottes, France and SIR, 12A, Montpellier, France), or on object-oriented representation of the knowledge (EXPRIM from our laboratory). The main problem is, as usually in artificial intelligence applications, to transfer human expertise into an adapted knowledge base. The advantage of experts systems over man are their reproducibility of answer and their availability. PMID:2064087

  9. Expert system for transuranic waste assay

    International Nuclear Information System (INIS)

    Transuranic wastes are generated at the Savannah River Site (SRS) as a result of routine production of nuclear materials. These wastes contain Pu-238 and Pu-239 and are placed into lined 55-gallon waste drums. The drums are placed on monitored storage pads pending shipment to the Waste Isolation Pilot Plant in New Mexico. A passive-active neutron (PAN) assay system is used to determine the mass of the radioactive material within the waste drums. Assay results are used to classify the wastes as either low-level or transuranic (TRU). During assays, the PAN assay system communicates with an IBM-AT computer. A Fortran computer program, called NEUT, controls and performs all data analyses. Unassisted, the NEUT program cannot adequately interpret assay results. To eliminate this limitation, an expert system shell was used to write a new algorithm, called the Transuranic Expert System (TRUX), to drive the NEUT program and add decision making capabilities for analysis of the assay results. The TRUX knowledge base was formulated by consulting with human experts in the field of neutron assay, by direct experimentation on the PAN assay system, and by observing operations on a daily basis. TRUX, with its improved ability to interpret assay results, has eliminated the need for close supervision by a human expert, allowing skilled technicians to operate the PAN assay system. 4 refs., 1 fig., 4 tabs

  15. Expert initial review of Columbia River Basin salmonid management models: Summary report

    International Nuclear Information System (INIS)

    Over the past years, several fish passage models have been developed to examine the downstream survival of salmon during their annual migration through the Columbia River reservoir system to below Bonneville Dam. More recently, models have been created to simulate the survival of salmon throughout the entire life cycle. The models are used by various regional agencies and native American tribes to assess impacts of dam operation, harvesting, and predation on salmonid abundance. These models are now also being used to assess extinction probabilities and evaluate restoration alternatives for threatened and endangered salmonid stocks. Oak Ridge National Laboratory (ORNL) coordinated an initial evaluation of the principal models by a panel of outside, expert reviewers. None of the models were unequivocally endorsed by any reviewer. Significant strengths and weaknesses were noted for each with respect to reasonability of assumptions and equations, adequacy of documentation, adequacy of supporting data, and calibration procedures. Although the models reviewed differ in some important respects, all reflect a common conceptual basis in classical population dynamic theory and a common empirical basis consisting of the available time series of salmonid stock data, hydrographic records, experimental studies of dam passage parameters, and measurements of reservoir mortality. The results of this initial review are not to be construed as a comprehensive scientific peer review of existing Columbia River Basin (CRB) salmon population models and data. The peer review process can be enhanced further by a dynamic exchange regional modelers and scientific panel experts involving interaction and feedback

    ENGLISH ABSTRACT: Artificial intelligence techniques are rapidly emerging as important contributors to more effective management. One of the greatest growth areas probably lies in the use of Expert System methodology for supporting managerial decision processes.
    Existing Decision Support Systems often attempt to apply analytical techniques in combination with traditional data access and retrieval functions. One of the problems usually encountered while developing such decision support systems is the need to transform an unstructured problem environment into a structured analytical model. Using an expert system approach to strategic decision making in such unstructured problem environments may provide significant advantages.
    The financial Risk diagnostic EXpert System (REXS concentrates on Financial Risk Analysis. Based on a Forecasting Model the system will, with the support of several expert system knowledge bases, attempt to evaluate the financial risk of a business and provide guidelines for improvement.

    Considerable interest has been expressed for developing a stable U.S. production capacity for medical isotopes and particularly for molybdenum- 99 (99Mo). This is motivated by recent re-ductions in production and supply worldwide. Consistent with U.S. nonproliferation objectives, any new production capability should not use highly enriched uranium fuel or targets. Conse-quently, Aqueous Homogeneous Reactors (AHRs) are under consideration for potential 99Mo production using low-enriched uranium. Although the Nuclear Regulatory Commission (NRC) has guidance to facilitate the licensing process for non-power reactors, that guidance is focused on reactors with fixed, solid fuel and hence, not applicable to an AHR. A panel was convened to study the technical issues associated with normal operation and potential transients and accidents of an AHR that might be designed for isotope production. The panel has produced the requisite AHR licensing guidance for three chapters that exist now for non-power reactor licensing: Reac-tor Description, Reactor Coolant Systems, and Accident Analysis. The guidance is in two parts for each chapter: 1) standard format and content a licensee would use and 2) the standard review plan the NRC staff would use. This guidance takes into account the unique features of an AHR such as the fuel being in solution; the fission product barriers being the vessel and attached systems; the production and release of radiolytic and fission product gases and their impact on operations and their control by a gas management system; and the movement of fuel into and out of the reactor vessel.

  19. How do music experts and non-experts evaluate the vocal accuracy of operatic singing voices?

    OpenAIRE

    Larrouy, Pauline; Nowak, Marion; Morsomme, Dominique

    2013-01-01

    Professional singers are expected to sing in tune. However, when an operatic singing technique is employed, the objective measurement of the vocal accuracy (i.e. pitch interval deviation) shows particularly low scores, whatever the melody performed. This study focuses on the perceptual judgment of operatic voices in order to observe the evaluation process of singing voice accuracy by music experts and non-experts. In addition, this study aims to better understand the relationship between the ...

  20. Micro-inverter solar panel mounting

    Science.gov (United States)

    Morris, John; Gilchrist, Phillip Charles

    2016-02-02

    Processes, systems, devices, and articles of manufacture are provided. Each may include adapting micro-inverters initially configured for frame-mounting to mounting on a frameless solar panel. This securement may include using an adaptive clamp or several adaptive clamps secured to a micro-inverter or its components, and using compressive forces applied directly to the solar panel to secure the adaptive clamp and the components to the solar panel. The clamps can also include compressive spacers and safeties for managing the compressive forces exerted on the solar panels. Friction zones may also be used for managing slipping between the clamp and the solar panel during or after installation. Adjustments to the clamps may be carried out through various means and by changing the physical size of the clamps themselves.

    DEFF Research Database (Denmark)

    Sera, Dezso; Teodorescu, Remus; Rodriguez, Pedro

    This work presents the construction of a model for a PV panel using the single-diode five-parameters model, based exclusively on data-sheet parameters. The model takes into account the series and parallel (shunt) resistance of the panel. The equivalent circuit and the basic equations of the PV cell....../panel in Standard Test Conditions (STC) are shown, as well as the parameters extraction from the data-sheet values. The temperature dependence of the cell dark saturation current is expressed with an alternative formula, which gives better correlation with the datasheet values of the power temperature...... dependence. Based on these equations, a PV panel model, which is able to predict the panel behavior in different temperature and irradiance conditions, is built and tested....

  2. The Atomic Safety and Licensing Board Panel

    International Nuclear Information System (INIS)

    Through the Atomic Energy Act, Congress made is possible for the public to get a full and fair hearing on civilian nuclear matters. Individuals who are directly affected by any licensing action involving a facility producing or utilizing nuclear materials may participate in a formal hearing, on the record, before independent judges on the Atomic Safety and Licensing Board Panel (ASLBP or Panel). Frequently, in deciding whether a license, permit, amendment, or extension should be granted to a particular applicant, the Panel members must be more than mere umpires. If appropriate, they are authorized to go beyond the issues the parties place before them in order to identify, explore, and resolve significant questions involving threats to the public health and safety that come to a board's attention during the proceedings. This brochure explains the purpose of the panel. Also addressed are: type of hearing handled; method of public participation; formality of hearings; high-level waste; other panel responsibilities and litigation technology

  3. Noise Reduction in Double‐Panel Structures by Cavity and Panel Resonance Control

    OpenAIRE

    Ho, Jen-Hsuan; Berkhoff, Arthur

    2011-01-01

    This paper presents an investigation of the cavity and the panel resonance control in a double‐panel structure. The double‐panel structure, which consists of two panels with air in the gap, is widely adopted in many applications such as aerospace due to its light weight and effective transmission‐loss at high frequency. However, the resonance of the cavity and the poor transmission‐loss at low frequency limit its noise control performance. Applying active control forces on the panels or utili...

  4. Over-optimism Among Experts in Assessment and Foresight

    OpenAIRE

    Tichy, Gunther

    2002-01-01

    It is still disputed whether foresight exercises should be based on top-expert assessments or on a broader base of less specialised experts, and whether the self-rating of experts is an acceptable method. Using the German 1993 and the Austrian 1998 Technology Delphis, this study addresses both questions: Self-rating is in fact an appropriate method for selecting experts. But the assessment of self-rated top-experts tend to suffer from an optimism bias, due to the experts involvement and their...

    Fleishman, Erica; Burgman, Mark; Runge, Michael C; Schick, Robert S; Kraus, Scott

    2016-01-01

    Expert elicitation is a rigorous method for synthesizing expert knowledge to inform decision making and is reliable and practical when field data are limited. We evaluated the feasibility of applying expert elicitation to estimate population-level effects of disturbance on marine mammals. Diverse experts estimated parameters related to mortality and sublethal injury of North Atlantic right whales (Eubalaena glacialis). We are now eliciting expert knowledge on the movement of right whales among geographic regions to parameterize a spatial model of health. Expert elicitation complements methods such as simulation models or extrapolations from other species, sometimes with greater accuracy and less uncertainty. PMID:26610972

    2015-01-01

    An international expert panel was convened to deliberate the management of azole-resistant aspergillosis. In culture-positive cases, in vitro susceptibility testing should always be performed if antifungal therapy is intended. Different patterns of resistance are seen, with multi-azole and pan-azole resistance more common than resistance to a single triazole. In confirmed invasive pulmonary aspergillosis due to an azole-resistant Aspergillus, the experts recommended a switch from voriconazole to liposomal amphotericin B (L-AmB; Ambisome(®)). In regions with environmental resistance rates of ≥10%, a voriconazole-echinocandin combination or L-AmB were favoured as initial therapy. All experts recommended L-AmB as core therapy for central nervous system aspergillosis suspected to be due to an azole-resistant Aspergillus, and considered the addition of a second agent with the majority favouring flucytosine. Intravenous therapy with either micafungin or L-AmB given as either intermittent or continuous therapy was recommended for chronic pulmonary aspergillosis due to a pan-azole-resistant Aspergillus. Local and national surveillance with identification of clinical and environmental resistance patterns, rapid diagnostics, better quality clinical outcome data, and a greater understanding of the factors driving or minimising environmental resistance are areas where research is urgently needed, as well as the development of new oral agents outside the azole drug class.

  7. Employing expert systems for process control

    International Nuclear Information System (INIS)

    The characteristic features of expert systems are explained in detail, and the systems' application in process control engineering. Four points of main interest are there, namely: Applications for diagnostic tasks, for safety analyses, planning, and training and expert training. For the modelling of the technical systems involved in all four task fields mentioned above, an object-centred approach has shown to be the suitable method, as process control techniques are determined by technical objects that in principle are specified by data sheets, schematic representations, flow charts, and plans. The graphical surface allows these data to be taken into account, so that the object can be displayed in the way best suited to the individual purposes. (orig./GL)

  8. Demonstration of expert systems in automated monitoring

    International Nuclear Information System (INIS)

    The Reactor Systems Section of Oak Ridge National Laboratory's Instrumentation and Controls Division has been developing expertise in the application of artificial intelligence (AI) tools and techniques to control complex systems. One of the applications developed demonstrates the capabilities of a rule-based expert system to monitor a nuclear reactor. Based on the experience acquired with the demonstration described in this paper, a 2-yr program was initiated during fiscal year 1985 for the development and implementation of an intelligent monitoring adviser to the operators of the HFIR facility. The intelligent monitoring system will act as an alert and cooperative expert to relieve the operators of routine tasks, request their attention when abnormalities are detected, and provide them with interactive diagnostic aid and project action/effects information as needed or on demand

  9. Expert system for generating fuel movement procedures

    International Nuclear Information System (INIS)

    Commercial nuclear power reactors are required by federal law and their operating license to track and control the movement of nuclear fuel. Planning nuclear fuel movements during a refueling outage by hand is a tedious process involving an initial state and final state separated by physical and administrative constraints. Since the initial and final states as well as all constraints are known, an expert computer system for planning this process is possible. Turkey Point station worked with the Electric Power Research Institute (EPRI)-selected vendor to implement such a system. Over the course of a 2-yr period, the EPRI Fuel Shuffle Planning System evolved from a high-tech word processor to an expert system capable of planning all fuel movement sequences required to refuel a nuclear reactor core. Turkey Point site is composed to two pressurized water reactor units owned and operated by Florida Power and Light Company

  10. Conclusions of the groups of experts

General recommendations of the Groups of Experts concerning work still needed to develop to a sufficient degree techniques for treating rare events in reliability analyses of nuclear plants. A general discussion and conclusions are presented and final recommendations of the Task Force to CSNI are given

  11. A framework for real time expert systems

    International Nuclear Information System (INIS)

    Development of real time and on-line expert systems for diagnosis and prediction is a complex and ambitious goal. Rather than in the system itself, the complexity of the task is reflected in the advanced information models it requires. Therefore, the system lends itself to less ambitious yet very useful applications long desired by plant engineers and operators. One such application is post-trip analysis which reduces the amount of time necessary to determine whether or not a plant can be restarted after a trip; this analysis also determines if all automatic functions have been executed as intended. The paper shows how a task such as post-trip analysis can be embedded in the larger framework of expert systems and why this is a desirable way of development. Also, the exploration of speech recognition and speech output techniques for the man-machine interface is discussed. (author). 6 refs, 2 figs

  12. EXPERT-SYSTEM BASED MEDICAL STROKE PREVENTION

    Directory of Open Access Journals (Sweden)

    Anindito

    2013-01-01

    Full Text Available Stroke always comes unexpected and the general public is not usually aware of its symptoms. Individuals who have had their first stroke with permanent damage could become an economic burden to their family and a social burden to the society due to their unproductive nature. Stroke could be prevented and its risk factors have been identified. Through a stroke prevention information system, the user could be made more aware of stroke risks and symptoms. An expert system would be able to direct and motivate users to keep themselves healthy therefore preventing first and recurrent strokes. The expert system is built using an inference engine that provides stroke risk level based on information provided by the user. Information collected are self measured blood pressure, cigarettes consumed, amount of physical activity and body mass index. Users are presented with suggested preventive tasks to reduce their stroke risk.

  13. SELF LEARNING REAL TIME EXPERT SYSTEM

    Directory of Open Access Journals (Sweden)

    Latha B. Kaimal

    2013-02-01

    Full Text Available In a Power plant with a Distributed Control System ( DCS , process parameters are continuously stored in databases at discrete intervals. The data contained in these databases may not appear to contain valuable relational information but practically such a relation exists. The large number of process parameter values are changing with time in a Power Plant. These parameters are part of rules framed by domain experts for the expert system. With the changes in parameters there is a quite high possibility to form new rules using the dynamics of the process itself. We present an efficient algorithm that generates all significant rules based on the real data. The association based algorithms were compared and the best suited algorithm for this process application was selected. The application for the Learning system is studied in a Power Plant domain. The SCADA interface was developed to acquire online plant data.

  18. The UK system of recognising qualified experts

    International Nuclear Information System (INIS)

    EURATOM Basic Safety Standards (BSS) Directives have long included requirements for the involvement of qualified experts, the definition of which has scarcely changed since at least 1976. The Directive requirement, in the definition of qualified expert,, for competent authorities to recognise the capacity to act as a qualified expert has been interpreted by Member States in widely differing ways, ranging from the minimalist or case by case to the highly detailed and prescriptive. In the United Kingdom (UK), the qualified expert for occupational radiation protection is the radiation protection adviser and the competent authority is the Health and Safety Executive (HSE). The Ionising Radiations Regulations 1985, which largely implemented the 1980 BSS Directive, required an employer to appoint one or more radiation protection advisers for the purpose of advising him as to the observance of these Regulations and other health and safety matters in connection with ionising radiation. The Regulations addressed the question of recognition by forbidding an employer to appoint a person as a radiation protection adviser unless: that person was suitably qualified and experienced; the employer had notified the Health and Safety Executive in writing of the intended appointment at least 28 days in advance, giving the name of the person and particulars of his qualifications and experience and the scope of the advice he would be required to give; and the employer had received from HSE an acknowledgement in writing of the notification. This system allowed HSE to follow up and query any apparently unsuitable potential appointments while applying a light overall administrative touch. The Approved Code of Practice supporting the Regulations included advice on the qualifications, experience and qualities that the employer should look for in a suitable radiation protection adviser

    OpenAIRE

    Slawson, D. C.; Shaughnessy, A. F.

    1997-01-01

    Clinicians rely heavily on expert based systems-consultation with colleagues, journal reviews and textbooks, and continuing education activities-to obtain new information. The usefulness of sources such as these depends on the relevance and validity of the information and the work it takes to obtain it. Useful information can be distinguished from the useless by asking three questions: Does the information focus on an outcome that my patients care about? Is the issue common to my practice, an...
