    Nanoparticles may someday come to the rescue of people exposed to chemical, biological or radiological hazards. Argonne researchers are in the early testing stages of a system that would cleanse the blood of contaminants using tiny magnetic particles and a portable, external magnetic separator. Current methods of cleaning the blood of radioactive and other hazardous materials are mainly limited to dialysis and filtration techniques. Unfortunately, current medical procedures to detoxify human blood are restricted to only a few types of toxins, drastically limiting treatment options for exposed victims. Also, several important shortcomings exist with the currently available technology. Treatments can take several hours to complete, require the turnover and filtration of large volumes of blood, are rather inefficient at removing toxins and can be risky for the patient. For these reasons, current methods are mostly restricted to patients with kidney failure and certain types of drug overdoses. Alternative treatments exist, such antibodies and chelators, substances that combine with and neutralize toxins. These treatments can be used for specific kinds of toxins, but are not efficient. In addition, they can cause serious side effects, such as allergic reactions and organ failure. 'The best that doctors can do for most biohazard exposure is supportive treatment,' Kaminski said. 'This new system will be designed to directly remove the toxic agents from the bloodstream, quickly and efficiently.' The biohazard detoxification system will use biodegradable nanoparticles between 100 and 5,000 nanometers (one nanometer is one ten-millionth of a centimeter) in size, small enough to pass through tiny blood vessels and yet large enough to avoid being filtered from the bloodstream by the kidneys.

    Spent mushroom compost (SMC) is a major waste of the mushroom industry with low economic value. SMC arises after mushroom production in phase II compost (pIIC), predominantly comprising straw and chicken litter as principal raw ingredients. The majority of SMC waste is disposed off by application to agricultural land. It is an attractive proposition for utilising SMC as soil inorganic fertiliser supplementation. However, there is limited data available as to the consequences of this method of disposal either in terms of microbiological loading of food-borne pathogens and those of concern to mushroom industry itself. The resulting imbalance of the natural flora of the agricultural land has not been properly audited. This study aims to initially examine SMC for prevalence of faecal bacterial pathogens including Campylobacter spp., Salmonella spp. and Listeria monocytogenes that may arise from chicken litter. At another level, it aims to ascertain the pathogenic bacteria (Pseudomonas syringae, pv phaseolicola or tolasii) and fungal populations (Trichoderma, Verticillium species) originating mainly from the straw component of the SMC, which are of concern to the mushroom industry. Lastly, the study would also qualitatively identify the diversity of bacterial populations within SMC. This was largely accomplished through employment of rDNA, PCR and direct sequencing strategies on the culturable microflora. However, for specific mushroom pathogens, nucleic acids (DNA or RNA) were directly extracted from composts before subjecting to sequence analysis. In accordance with the current legislation (ABP 02/02, Animal By Products wastes disposal EC No. 1774/2002), it is imperative to regulate the farm wastes carrying residues from animal sources including SMC before they are regarded safe for land spreading operations.

    Exploration Class missions to Mars will require precautions against potential contamination by any native microorganisms that may be incidentally pathogenic to humans. While the results of NASA's Viking biology experiments of 1976 have been generally interpreted as inconclusive for surface organisms, the possibility of native surface life has never been ruled out and more recent studies suggest that the case for biological interpretation of the Viking Labeled Release data may now be stronger than it was when the experiments were originally conducted. It is possible that, prior to the first human landing on Mars, robotic craft and sample return missions will provide enough data to know with certainty whether or not future human landing sites harbor extant life forms. However, if native life is confirmed, it will be problematic to determine whether any of its species may present a medical risk to astronauts. Therefore, it will become necessary to assess empirically the risk that the planet contains pathogens based on terrestrial examples of pathogenicity and to take a reasonably cautious approach to bio-hazard protection. A survey of terrestrial pathogens was conducted with special emphasis on those pathogens whose evolution has not depended on the presence of animal hosts. The history of the development and implementation of Apollo anticontamination protocol and recent recommendations of the NRC Space Studies Board regarding Mars were reviewed. Organisms can emerge in nature in the absence of indigenous animal hosts and both infectious and non-infectious human pathogens are theoretically possible on Mars. The prospect of Martian surface life, together with the existence of a diversity of routes by which pathogenicity has emerged on Earth, suggests that the possibility of human pathogens on Mars, while low, is not zero. Since the discovery and study of Martian life can have long-term benefits for humanity, the risk that Martian life might include pathogens should not

    The recent report of the Mars 2020 Science Definition Team recommended that the mission accomplish broad and rigorous in situ science, including seeking biosignatures and acquiring a diverse set of samples intended to be stored in a cache for potential return to Earth at a later time. In developing the Mars 2020 mission NASA and its partners are beginning at least the promise (uncertainty #1) of a later sample return and will need to address important uncertainties with implications not only for the integrity of science, but also for public communication about the mission and associated decision making. In particular, they will have to address the requirement, reaffirmed by multiple US National Research Council reports, to contain such a sample when it is returned (uncertainty #2) and not release it, unsterilized (uncertainty #3), until tests prove that it does not contain a biohazard (uncertainty #4). And of course we won't know what the samples are like until they are collected (uncertainty #5, et al.). In an ongoing process of scientific analysis and protocol development, NASA and its partners (such as the European Space Agency) have continued to discuss the requirements for containment and how it should be defined and implemented at a high (how high?) degree of certainty. How the protocol and requirements will be finalized, and how the decision process to approve them will be structured are all part of a communications picture that changes not only based on the technical aspects of the mission, but on other public events that may have little or nothing to do with the exploration of space. Now that the Mars 2020 mission has been moved forward as the first step in a sample-return train, NASA will face a robust communications challenge that will not only be complicated by the uncertainties numbered above, but by the uncertainties associated with any large-budget science program that depends on public funding, a situation fraught with its own uncertainties, to be

    International Nuclear Information System (INIS)

    Highlights: ► VOCs and biohazards emitted during garbage compressing process were monitored. ► BTF–PC integrated reactor was employed for VOCs and biohazards removal. ► Health risk of target VOCs and biohazards were assessed before and after treatment. -- Abstract: Volatile organic compounds (VOCs) and biohazards air pollution in municipal solid waste transfer station were investigated. As compressor working, the concentrations of almost all quantified 14 VOCs (0.32–306.03 μg m−3) were much higher than those as compressor off (0–13.31 μg m−3). Comparatively, only 3 VOCs with extremely low concentrations could be detected at control area. Total microorganism was 7567 CFU m−3 as compressor working, which was 1.14 and 6.22 times higher than that of compressor off and control area, respectively. Bacteria were the most abundant microorganism at all three sampling places. At pilot-scale, during whole 60-day treatment, for VOCs, the average removal efficiencies were over 92% after biotrickling filter–photocatalytic (BTF–PC) treatment. Although non-cancer and cancer risks of some VOCs were over the concern level before treatment, almost all VOCs were removed substantially and both potential risks were below the concern after BTF–PC treatment. Additionally, biohazard concentrations decreased dramatically and air quality was purified from polluted to cleanness after PC treatment. All results demonstrated that the integrated technology possessed high removal capacity and long stability for the removal of VOCs and biohazards at a pilot scale

  14. Gamma irradiation for control of biohazards in aqua cultured fishery products

    International Nuclear Information System (INIS)

    As compared with capture fisheries, aquacultured fish and shellfish are more associated with biological and chemical hazards due to possibilities of their contamination through agents from both freshwater and coastal ecosystems. With enhanced export potential of aquacultured items consumers may be increasingly exposed to these hazards. The habit of eating raw fishery products by consumers in several Asian countries may add to widespread outbreak of aquaculture mediated hazards. This article is intended to briefly discuss the various biological hazards associated with aquaculture operations and the scope of using ionizing radiation in alleviation of the problems. (author)

  15. Bio-fuels - biohazard

    International Nuclear Information System (INIS)

    Politicians have a clear explanation for growing commodity prices. It is all the fault of speculators. It is easy to point the finger at an imaginary enemy. It is more difficult and from the point of view of a political career suicidal to admit one's mistakes. And there are reasons for remorse. According to studies prepared by the OECD and the World Bank bio-fuels are to be blame for high food prices. The bio-fuel boom that increases the demand for agro-commodities has been created by politicians offering generous subsidies. And so farming products do not end up on the table, but in the fuel tanks of cars in the form of additives. And their only efficiency is that they make food more expensive. The first relevant indication that environmentalist tendencies in global politics have resulted in shortages and food price increases can be found in a confidential report prepared by the World Bank. Parts of the report were leaked to the media last month. According to this information growing bio-fuel production has resulted in a food price increase by 75%. The theory that this development was caused by speculators and Chinese and Indian demand received a serious blow. And the OECD report definitely contradicted the excuse used by the politicians. According to the report one of the main reasons for growing food prices are generously subsidized bio-fuels. Their share of the increase of demand for agro-commodities in 2005 -2007 was 60% according to the study. (author)

    Full Text Available Biotoxins are toxic substances produced by a living organism that cause diseases in humanbeings, animals, or plants. The agent may be lethal or incapacitating. The new, emerging threatagents are biotoxins produced by animals, plants, fungi, and bacteria. Many types of organismsproduce substances that are toxic to humans. Examples of such biotoxins are botulinum toxin,tetanus toxin, and ricin. Several bioactive molecules produced by the pharmaceutical industrycan be even more toxic than the classical chemical warfare agents. Such new agents, like thebiotoxins and bioregulators, often are called mid-spectrum agents. The threat to human beingsfrom agents developed by modern chemical synthesis and by genetic engineering also must beconsidered, since such agents may be more toxic or more effective in causing death orincapacitation than classical warfare agents. By developing effective medical protection andtreatment against the most likely chemical and mid-spectrum threat agents, the effects of suchagents in a war scenario or following a terrorist attack can be reduced. Toxin-mediated diseaseshave made human beings ill for millennia. The use of biological agents as weapons of terror hasnow been realised, and separating naturally occurring disease from bioterroristic events hasbecome an important public health goal.

  18. Advantages of combined touch screen technology and text hyperlink for the pathology grossing manual: a simple approach to access instructive information in biohazardous environments.

    Gross examination, encompassing description, dissection, and sampling, is a complex task and an essential component of surgical pathology. Because of the complexity of the task, standardized protocols to guide the gross examination often become a bulky manual that is difficult to use. This problem is further compounded by the high specimen volume and biohazardous nature of the task. As a result, such a manual is often underused, leading to errors that are potentially harmful and time consuming to correct-a common chronic problem affecting many pathology laboratories. To combat this problem, we have developed a simple method that incorporates complex text and graphic information of a typical procedure manual and yet allows easy access to any intended instructive information in the manual. The method uses the Object-Linking-and-Embedding function of Microsoft Word (Microsoft, Redmond, WA) to establish hyperlinks among different contents, and then it uses the touch screen technology to facilitate navigation through the manual on a computer screen installed at the cutting bench with no need for a physical keyboard or a mouse. It takes less than 4 seconds to reach any intended information in the manual by 3 to 4 touches on the screen. A 3-year follow-up study shows that this method has increased use of the manual and has improved the quality of gross examination. The method is simple and can be easily tailored to different formats of instructive information, allowing flexible organization, easy access, and quick navigation. Increased compliance to instructive information reduces errors at the grossing bench and improves work efficiency. PMID:17188327

    In an effort to gather information on the potential genetic hazards of existing or proposed energy-generating or -conversion systems, we have begun a correlated analytical and genetic analysis of a number of technologies. The work is divided into two phases: one deals with known compounds expected to occur in the environment through energy production, conversion, or use; the other deals with actual samples from existing or experimental processes. To approach the problems of coping with and testing large numbers of compounds, we set up a form of the "tier system." Operating units utilizing Salmonella, Escherichia coli, yeast, human leukocytes, mammalian cells, and Drosophila have been initiated. Various liquid-liquid extraction methods and column chromatographic separations have been applied to crude products and effluents from oil-shale, coal-liquefaction, and coal-gasification processes. Mutagenicity of the various fractions is assayed by means of reversion of histidine-requiring auxotrophs of Salmonella typhimurium; comparative studies are carried out with the other genetic systems. In order to incorporate metabolic activation of these fractions and compounds, rat liver homogenates (S-9) are used in the various assays. Results implicate chemicals occurring in the basic (ether-soluble) and the neutral fractions as potential genetic hazards. Chemical constituents of these fractions (identified or predicted) were tested individually for their mutagenic activity. PMID:367762

  4. Disposable Membrane Sensors for Biohazardous Substances

    Science.gov (United States)

    Petrov, Alexander G.

    The concept of bilayer lipid membrane sensing is elaborated. Disposable bilayer lipid membrane sensors permit both stochastic and deterministic sensing regimes. Technology for membrane sensor preparation is described in details. Stochastic membrane sensing using ion channels is described. Detection of cyano-bacterial toxins in waters by means of a stochastic sensing (ion channel induction) reveals a signature for a particular toxin type. This signature is especially well revealed by using the method of current-voltage surfaces, which establishes a bridge between stochastic and deterministic sensing by applying a time-averaging procedure. Flexoelectricity of membranes provides another way of deterministic sensing, of a stimulus-response type. The flexoelectric response is modulated by adsorption of the analyte over the membrane surface. Detection of environmental pollution of waters by heavy metal ions (Cd++ and Hg++) is thereby rendered possible. This approach is confronted with a stochastic sensing of the same metal ions by alteration of the channel open/closed probability and average channel current of two familiar channels, gramicidin and alamethicin.

    Plastic materials used for food packaging are clean but not sterile when the food is just packaged. Accidental wet contamination may occur at every moment between packaging and opening by the consumer: on polyethylene (PET), bacteria may adhere strongly and constitute a biofilm in less than 24 h. By rolling on themselves, PET sheets may contaminate food. We tried to show that contact with salted foodstuffs favoured microbial recovery. Four strains were chosen to perform biofilms on PET: Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Escherichia coli. Biofilms were dried up 24 h. Biofilm bacteria were stressed by adhesion, by starvation and by dehydration. However, they were capable of recovery in salted solutions or media, probably because one (or more) stress protected them against another stress. Stress was demonstrated by stress protein production, by mean of electrophoresis, and membrane lesions by mean of flow cytometry. Stress recovery was performed in aqueous salted solutions or salted brain-heart infusion with NaCl 9, 15, 20 and 30 g/l. Staphylococci were more sensitive to these stresses and recovery was a function of salt concentration. Gram-negative bacteria were little affected by stresses; salt effects were less important. If all these biofilms were capable of recovery from stresses in salted media, flexible PET could possibly lead to a health hazard when it is used for wet salt meats, e.g. PMID:10791750

    Industrial hygienists have knowledge of sampling techniques, aerosol physics, ventilation, filtration as well as personnel protective devices and clothing which provide them with needed skills. They are dedicated to health protection and do not have a personal interest in the success of a particular experiment or analysis. They are familiar with training techniques and may sometimes be more effective in teaching technicians and animal handlers than the M.D., D.V.M. or Ph.D. professional. They have a familiarity with a broad range of health hazards, from carcinogens and toxic chemicals to potentially explosive mixtures, and can monitor and advise on a wide range of laboratory safety problems.

    identifying the perception of health care workers of different categories from a specialized institution in emergency health service in the city of Goiânia regarding the context involving biohazard accidents. Firstly, 382 workers were given a questionnaire in order to identify those who had experienced an accident, 39 of which also took part in an interview addressing the general aspects of the accidents. Among the main accident causes to be highlighted are: unattention, non-adherence to preventive measures, patient's severity and hurry. Among the experienced feelings the main ones are: inconfidence, fear of contamination, rage, and even calmness. Half reported no consequence resulted from the accident. Data points to the need of self-worth concerning the worker's health and also of programs aiming at occupational safety enhancemnt.

  10. Operator Fundamentals

    International Nuclear Information System (INIS)

    Recent events show the need for constant attention on the operator fundamentals, in the commercial nuclear industry. The first report about decline in the application of operator fundamentals during plant operational activities and transient situations was issued in July 2005. Analyses of the events recorded during 18 month period between 2010 and 2011 show similar causes and contributors like it was before July 2005. Due to that fact, the WANO issued SOER 2013-1 Operator Fundamentals Weaknesses with proposed suggestions how to analyse area of operator fundamentals and gives recommendations for effective and sustainable corrective actions. Operator fundamentals are the essential knowledge, skills, behaviours, and practices that operating crews need to apply to operate the plant effectively. These fundamentals are as follows: · Monitoring plant indications and conditions closely · Controlling plant evolutions precisely · Operating the plant with a conservative bias · Working effectively as a team · Having a solid understanding of plant design, engineering principles, and sciences. NEK analysed area of operator fundamentals and verified how consistently the basic principles in the plant control are followed in practice. Some opportunities for improvement were recognized for the training area, operational procedures format improvement and improvement in process of preparation of the planned activities during power operation or during plant shutdown. Among other measures, stability in operation with a sufficient safety margin can be achieved only through continuous monitoring of the operational practice and by constant highlighting of the operational standards.

  19. Operator lattices

    International Nuclear Information System (INIS)

    The finite-element method enables us to convert the operator differential equations of a quantum field theory into operator difference equations. These difference equations are consistent with the requirements of quantum mechanics and they do not exhibit fermion doubling, a problem that frequently plagues lattice treatments of fermions. Guage invariance can also be incorporated into the difference equations. On a finite lattice the operator difference equations can be solved in closed form. For the case of the Schwinger model the anomaly is computed and results in excellent agreement are obtained with the known continuum value

  2. Operator theory

    CERN Document Server

    2015-01-01

    A one-sentence definition of operator theory could be: The study of (linear) continuous operations between topological vector spaces, these being in general (but not exclusively) Fréchet, Banach, or Hilbert spaces (or their duals). Operator theory is thus a very wide field, with numerous facets, both applied and theoretical. There are deep connections with complex analysis, functional analysis, mathematical physics, and electrical engineering, to name a few. Fascinating new applications and directions regularly appear, such as operator spaces, free probability, and applications to Clifford analysis. In our choice of the sections, we tried to reflect this diversity. This is a dynamic ongoing project, and more sections are planned, to complete the picture. We hope you enjoy the reading, and profit from this endeavor.

  3. Operator training

    International Nuclear Information System (INIS)

    The traditional operator job is changing, which among other things has generated a need for better job training. Surprisingly increased process automation has lead to increased operator qualifications, i.e. basic job training but also up-date and rehearsal training within certain fixed intervals. There are several, similar models for instructional system development available in the literature. One model which is of special interest integrates Operator Training development and Man-Machine Interfaces development. The extent to which Systematic Operator Training has been implemented varies with branches and companies. The nuclear power branch is given as an example in the report. This branch probably represents something better than the average among the process industries.(author)

    NASA operates high value critical equipment (HVCE) that requires trouble shooting, periodic maintenance and continued monitoring by Operations staff. The complexity HVCE and information required to maintain and trouble shoot HVCE to assure continued mission success as paper is voluminous. Training on new HVCE is commensurate with the need for equipment maintenance. LaRC Research Directorate has undertaken a proactive research to support Operations staff by initiation of the development and prototyping an electronic computer based portable maintenance aid (Operator's Assistant). This research established a goal with multiple objectives and a working prototype was developed. The research identified affordable solutions; constraints; demonstrated use of commercial off the shelf software; use of the US Coast Guard maintenance solution; NASA Procedure Representation Language; and the identification of computer system strategies; where these demonstrations and capabilities support the Operator, and maintenance. The results revealed validation against measures of effectiveness and overall proved a substantial training and capability sustainment tool. The research indicated that the OA could be deployed operationally at the LaRC Compressor Station with an expectation of satisfactorily results and to obtain additional lessons learned prior to deployment at other LaRC Research Directorate Facilities. The research revealed projected cost and time savings.

  1. Control rod operation device

    International Nuclear Information System (INIS)

    Purpose: To reduce operator's operation burdens in the low power state, while moderate his mental burdens upon high power state for the operation of control rod operation device. Constitution: Coordinate of main control rods to be operated, aimed insertion and withdrawal positions and velocity are calculated by the control rod operation sequence and the control rod worth table, to output a control rod selection signal and a control rod operation signal. The control rod operation device conducts extraction or insertion of control rods by these signals. In this way, the operator can automatically operate the control rods by merely manipulating the control rod operation device, by which the operator's operation burden can be reduced in low power state. Further, since the selection of the control rods, the operation speed, etc. are judged by an electronic computer also upon high reactor power state, operator's metal burdens can be moderated.

  5. Protein radioiodination in a radioassay laboratory: evaluation of commercial Na125I reagents and related biohazards

    International Nuclear Information System (INIS)

    Three commercial Na125I solutions (Amersham, New England Nuclear, and Union Carbide) have been examined with respect to multiple parameters affecting their use in the radioiodination of three representative peptides (insulin, growth hormone, and gastrin): % of radioiodine incorporation in protein; immunoreactivity and non-specific binding properties of the radiolabeled proteins; pH, volatility, and radionuclidic purity of radioiodine solutions; and vial construction with respect to multidose use. All three commercial Na125I produced radioiodinated proteins of good quality for use in radioligand assays. The radioiodines differed with respect to the amount of iodine released during initial vial opening as a consequence of different pH levels. Two of the three products were shipped in vials with poor construction with respect to multidose use. Selection of a radioiodine was therefore reduced to the secondary considerations of iodine volatility and vial construction. The volatilized radioiodine observed during the spill of millicuries quantities of unbuffered pH 7.5 Na125I was 14 microcuries per millicurie within the first 30 minutes. One thickness of rubber gloves reduced potential skin contamination from an accidental spill to insignificant levels: 20-30 picocuries per microcurie. Common good housekeeping procedures: i.e. rubber gloves, laboratory coat and a fume hood were found to be sufficient protection to eliminate most radioiodine volatility and contamination hazards associated with protein radiolabeling procedures

  9. Conduct of operations: establishing operational focus and setting operational standards

    International Nuclear Information System (INIS)

    Due to the nature of our business, we have often tended to focus on the technological aspects of the nuclear industry. The focus of this paper is directed towards the importance of addressing the people skills, attitudes, and 'culture' within, and surrounding, our facilities as key areas of improvement. Within Ontario Hydro Nuclear (OLIN) we have developed the terminology 'event free' operation and 'event free' culture. 'Event Free' recognizes errors as a part of human performance. 'Event Free' takes into account human weaknesses, and provides tools (such as standards) to manage, control, and mitigate errors. In essence, 'Event Free' encompasses two concepts: 1. Prevent errors from occurring; 2. If an error is made, catch it before it can affect safe operation of the facility, learn from the error, and ensure that it does not happen again. In addressing these business realities, Ontario Hydro has identified a number of key support mechanisms and corresponding performance standards that are essential for achieving operating excellence and an 'event free' business culture. This paper will discuss two operational aspects of an 'event free' culture, the first being a set of expectations to enhance the culture, and the second an example of cultural change: 1. Operating Standards - establishing clear expectations for human performance in operating staff; 2. Operational Focus - the understanding that, as a nuclear worker, you should consider every task, activity, in fact everything you do in this business, for the potential to affect safe and reliable operation of a nuclear facility. Note that although the term 'Operational' appears in the title, this concept applies to every individual in the nuclear business, from the cleaner, to the Board of Directors, to the external supplier.

    In this paper we consider the problem of the existence of higher derivatives of the function $t\\mapsto\\f(A+tK)$, where $\\f$ is a function on the real line, $A$ is a self-adjoint operator, and $K$ is a bounded self-adjoint operator. We improve earlier results by Sten'kin. In order to do this, we give a new approach to multiple operator integrals. This approach improves the earlier approach given by Sten'kin. We also consider a similar problem for unitary operators.

    Fateman, Richard; Grossman, Robert

    1989-01-01

    The symbolic computation of operator expansions is discussed. Some of the capabilities that prove useful when performing computer algebra computations involving operators are considered. These capabilities may be broadly divided into three areas: the algebraic manipulation of expressions from the algebra generated by operators; the algebraic manipulation of the actions of the operators upon other mathematical objects; and the development of appropriate normal forms and simplification algorithms for operators and their actions. Brief descriptions are given of the computer algebra computations that arise when working with various operators and their actions.

  20. Operating System Security

    CERN Document Server

    Jaeger, Trent

    2008-01-01

    Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build "secure" operating systems - operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we examine past research that outlines the requirements for a secure operating system and research that implements example systems that aim for such requirements. For system designs that aimed to

  1. Training and Tactical Operationally Responsive Space Operations

    Science.gov (United States)

    Sorensen, B.; Strunce, R., Jr.

    Current space assets managed by traditional space system control resources provide communication, navigation, intelligence, surveillance, and reconnaissance (ISR) capabilities using satellites that are designed for long life and high reliability. The next generation Operationally Responsive Space (ORS) systems are aimed at providing operational space capabilities which will provide flexibility and responsiveness to the tactical battlefield commander. These capabilities do not exist today. The ORS communication, navigation, and ISR satellites are being designed to replace or supplement existing systems in order to enhance the current space force. These systems are expected to rapidly meet near term space needs of the tactical forces. The ORS concept includes new tactical satellites specifically designed to support contingency operations such as increased communication bandwidth and ISR imagery over the theater for a limited period to support air, ground, and naval force mission. The Concept of Operations (CONOPS) that exists today specifies that in addition to operational control of the satellite, the tasking and scheduling of the ORS tactical satellite for mission data collection in support of the tactical warfighter will be accomplished within the Virtual Mission Operations Center (VMOC). This is very similar to what is currently being accomplished in a fixed Mission Operations Center on existing traditional ISR satellites. The VMOC is merely a distributed environment and the CONOPS remain virtually the same. As a result, there is a significant drawback to the current ORS CONOPS that does not account for the full potential of the ORS paradigm for supporting tactical forces. Although the CONOPS approach may be appropriate for experimental Tactical Satellites (TacSat), it ignores the issues associated with the In-Theater Commander's need to own and operate his dedicated TacSat for most effective warfighting as well as the Warfighter specific CONOPS. What is needed

  2. Plant operation monitor

    International Nuclear Information System (INIS)

    An operation monitor for a neutron injection device comprises a transmission time zone control means for judging, determining and outputting a transmission enabling time and a transmission disabling time by operation cycle data and a standard timing, and a operation value transmission control means for demanding operation value transmission only during the transmission enabling time. The transmission time zone control means judges and controls the time zone for changing the plant operation value and changes the operation value only when the plant is in a stand-by state and transmission is possible. The operation value is not changed during operation. Since transmission is conducted while avoiding the plant operation period in which the computer load is great, the load is dispersed. Since it is not necessary for an operator to pay attention separately to a plant operation period or a stand-by state and he can always demand an operation value change, time control is easy and operator's psychological burden is reduced.

  6. Launch operations efficiency

    Science.gov (United States)

    Diloreto, Clem; Fischer, Carl; Atkins, Bob

    1988-01-01

    The paper discusses launch operations from a program perspective. Launch operations cost is a significant part of program cost. New approaches to launch operations, integrated with lessons learned, have the potential to increase safety and reliability as well as reduce cost. Operational efficiency must be an initial program goal. Design technology and management philosophy must be implemented early to ensure operational cost goals. Manufacturing cost and launch cost are related to operational efficiency. True program savings can be realized through implementation of launch operations cost saving approaches which do not correspondingly increase cost in other program areas such as manufacturing and software development and maintenance. Launch rate is a key factor in the cost/flight analysis and the determination of launch operations efficiency goals.

  15. The Replace Operator

    CERN Document Server

    Karttunen, L

    1995-01-01

    This paper introduces to the calculus of regular expressions a replace operator, ->, and defines a set of replacement expressions that concisely encode several alternate variations of the operation. The basic case is unconditional obligatory replacement: UPPER -> LOWER Conditional versions of replacement, such as, UPPER -> LOWER || LEFT _ RIGHT constrain the operation by left and right contexts. UPPER, LOWER, LEFT, and RIGHT may be regular expressions of any complexity. Replace expressions denote regular relations. The replace operator is defined in terms of other regular expression operators using techniques introduced by Ronald M. Kaplan and Martin Kay in "Regular Models of Phonological Rule Systems" (Computational Linguistics 20:3 331-378. 1994).

    A systematic theory on the appropriate spin operators for the relativistic states is developed. For a massive relativistic particle with arbitrary nonzero spin, the spin operator should be replaced with the relativistic one, which is called in this paper as moving spin. Further the concept of moving spin is discussed in the quantum field theory. A new is constructed. It is shown that, in virtue of the two operators, problems in quantum field concerned spin can be neatly settled.

  14. Operator interface programs for KSTAR operation

    International Nuclear Information System (INIS)

    Beginning the first plasma discharging experiment of KSTAR since 2008, KSTAR performed the third plasma discharging experiment by 2010. During the experiment of three times, KSTAR OPerator Interface (OPI) programs have been developed for KSTAR operation by itself. OPI programs used in KSTAR were implemented by KSTAR widget plug-in Toolkit (KWT). The KWT means the plug-in library implemented by Qt-based user interface development software. The main purpose of developing the KWT library is to implement full automation libraries having interface with the automated EPICS channel access (CA) guaranteeing the flexibility for requirements of operators. In addition, it has advantages in minimizing human code error and maximizing utilization of the limited human resource. According to the increasing of control systems, a number of OPI servers connected to one EPICS gateway server caused the connection problem and increased the amount of the network data packets. To solve these problems, an algorithm of “CachedChannelAccess” for shared memory base was implemented into an inner logic of the KWT library. KSTAR control system monitoring (CSM) program is one of applications developed by using KWT library. The function of CSM program is to notify alarm to operators by checking health status of every server's network health status and resource (cpu, memory, network packets, disk usage rate and system/user defined process) usage state. Another application is a post-shot sequencing program which is activated after every shot is completed. This application is to display major plasma parameters and diagnostic data in chart form, to save this data to database, and to transfer a chart image file to a web server. This paper describes the technical details how to develop OPI applications which have high productivity using Qt on the EPICS-based control system

  20. Operational safety reliability research

    International Nuclear Information System (INIS)

    Operating reactor events such as the TMI accident and the Salem automatic-trip failures raised the concern that during a plant's operating lifetime the reliability of systems could degrade from the design level that was considered in the licensing process. To address this concern, NRC is sponsoring the Operational Safety Reliability Research project. The objectives of this project are to identify the essential tasks of a reliability program and to evaluate the effectiveness and attributes of such a reliability program applicable to maintaining an acceptable level of safety during the operating lifetime at the plant

    1991-01-01

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that Stirling machines are capable of reliable and lengthy lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and were not expected to operate for any lengthy period of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered.

    1991-01-01

    The NASA Science Internet (NSI) Network Operations Staff is responsible for providing reliable communication connectivity for the NASA science community. As the NSI user community expands, so does the demand for greater interoperability with users and resources on other networks (e.g., NSFnet, ESnet), both nationally and internationally. Coupled with the science community's demand for greater access to other resources is the demand for more reliable communication connectivity. Recognizing this, the NASA Science Internet Project Office (NSIPO) expands its Operations activities. By January 1990, Network Operations was equipped with a telephone hotline, and its staff was expanded to six Network Operations Analysts. These six analysts provide 24-hour-a-day, 7-day-a-week coverage to assist site managers with problem determination and resolution. The NSI Operations staff monitors network circuits and their associated routers. In most instances, NSI Operations diagnoses and reports problems before users realize a problem exists. Monitoring of the NSI TCP/IP Network is currently being done with Proteon's Overview monitoring system. The Overview monitoring system displays a map of the NSI network utilizing various colors to indicate the conditions of the components being monitored. Each node or site is polled via the Simple Network Monitoring Protocol (SNMP). If a circuit goes down, Overview alerts the Network Operations staff with an audible alarm and changes the color of the component. When an alert is received, Network Operations personnel immediately verify and diagnose the problem, coordinate repair with other networking service groups, track problems, and document problem and resolution into a trouble ticket data base. NSI Operations offers the NSI science community reliable connectivity by exercising prompt assessment and resolution of network problems.

    The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as our main tool. A set of moves we define in the set of the operator spin foams (among other operations) allows us to split the faces and the edges of the foams. We assign to each operator spin foam a contracted operator, by using the contractions at the vertices and suitably adjusted face amplitudes. The emergence of the face amplitudes is the consequence of assuming the invariance of the contracted operator with respect to the moves. Next, we define spin foam models and consider the class of models assumed to be symmetric with respect to the moves we have introduced, and assuming their partition functions (state sums) are defined by the contracted operators. Briefly speaking, those operator spin foam models are invariant with respect to the cellular decomposition, and are sensitive only to the topology and colouring of the foam. Imposing an extra symmetry leads to a family we call natural operator spin foam models. This symmetry, combined with assumed invariance with respect to the edge splitting move, determines a complete characterization of a general natural model. It can be obtained by applying arbitrary (quantum) constraints on an arbitrary BF spin foam model. In particular, imposing suitable constraints on a spin(4) BF spin foam model is exactly the way we tend to view 4D quantum gravity, starting with the BC model and continuing with the Engle-Pereira-Rovelli-Livine (EPRL) or Freidel-Krasnov (FK) models. That makes our framework directly applicable to those models. Specifically, our operator spin foam framework can be translated into the language of spin foams and partition functions. Among our natural spin foam models there are the BF spin foam model, the BC model, and a model corresponding to the EPRL intertwiners. Our operator spin foam framework can also be used for more general spin

  8. Plant operation method

    International Nuclear Information System (INIS)

    A precoating material is coated on the surface of a hollow thread membrane filter before the start-up operation of a plant. With such a constitution, since the precoating material captures solid materials to prevent them from reaching the surface of the membrane of the filter when the clogging-promoting solid materials are present in condensates, the clogging of the filter membrane can be suppressed effectively. In addition, since the precoating operation is limited to the time before the actuation operation, the increase of the amount of wastes can be minimized. (T.M.)

  11. Operating experience feedback

    International Nuclear Information System (INIS)

    Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations. Information system helps everybody to track the process of evaluation and proper logging of activities. (author)

  12. Operator Algebras of Functions

    CERN Document Server

    2009-01-01

    We present some general theorems about operator algebras that are algebras of functions on sets, including theories of local algebras, residually finite dimensional operator algebras and algebras that can be represented as the scalar multipliers of a vector-valued reproducing kernel Hilbert space. We use these to further develop a quantized function theory for various domains that extends and unifies Agler's theory of commuting contractions and the Arveson-Drury-Popescu theory of commuting row contractions. We obtain analogous factorization theorems, prove that the algebras that we obtain are dual operator algebras and show that for many domains, supremums over all commuting tuples of operators satisfying certain inequalities are obtained over all commuting tuples of matrices.

  18. Selecting reactor operator trainees

    International Nuclear Information System (INIS)

    Reactor operator trainee selection tends to be more effective if tailored to a utility's unique needs, and offers the organization a better chance for compliance with Federal regulations than if selection methods are adopted without benefit of local research. The costs of operator training range from $50,000 to $100,000. The test validity relative to a variety of training grades and performance measures is reviewed. Of interest is the degree to which tests differentiate reactor operators with respect to simulator training grades and performance in simulator operation; forms of evaluation which have become fairly standard throughout the power industry. The tests administered to each individual were selected because of their presumed relevance to training grades, and the aptitude measures are intended to assess an individual's potential to benefit from training. Tests, availability, form, the abilities they measure, and the time limit are described. (MCW)

  3. Adaptively Compressed Exchange Operator

    CERN Document Server

    Lin, Lin

    2016-01-01

    The Fock exchange operator plays a central role in modern quantum chemistry. The large computational cost associated with the Fock exchange operator hinders Hartree-Fock calculations and Kohn-Sham density functional theory calculations with hybrid exchange-correlation functionals, even for systems consisting of hundreds of atoms. We develop the adaptively compressed exchange operator (ACE) formulation, which greatly reduces the computational cost associated with the Fock exchange operator without loss of accuracy. The ACE formulation does not depend on the size of the band gap, and thus can be applied to insulating, semiconducting as well as metallic systems. In an iterative framework for solving Hartree-Fock-like systems, the ACE formulation only requires moderate modification of the code, and can be potentially beneficial for all electronic structure software packages involving exchange calculations. Numerical results indicate that the ACE formulation can become advantageous even for small systems with tens...

    The purpose of this research was to establish an operator performance indicator (OPI) that can be used by mining professionals/management to aid in the evaluation of dragline operators in surface coal mining. The OPI is defined as a ratio of hourly dragline production and hourly energy consumption, which needs to be maximised. A statistical approach based on confidence intervals is proposed as a means of classifying operators' performance. The results of an experiment conducted at a surface mine that is operated by one of the largest North American coal companies are discussed to demonstrate the practical application of developed method. The method applied in this article can also be adjusted and used for various mining equipment.

    International Nuclear Information System (INIS)

    Using systematic calculations in spinor language, we obtain simple descriptions of the second order symmetry operators for the conformal wave equation, the Dirac–Weyl equation and the Maxwell equation on a curved four-dimensional Lorentzian manifold. The conditions for existence of symmetry operators for the different equations are seen to be related. Computer algebra tools have been developed and used to systematically reduce the equations to a form which allows geometrical interpretation. (paper)

    Eriksson, Kjell [Det Norske Veritas (Norway); Davies, Ray [CC Technologies, Dublin, OH (United States)

    2005-07-01

    Pipeline operators are continuously working to improve the safety of their systems and operations. In the US both liquid and gas pipeline operators have worked with the regulators over many years to develop more systematic approaches to pipeline integrity management. To successfully manage pipeline integrity, vast amounts of data from different sources needs to be collected, overlaid and analyzed in order to assess the current condition and predict future degradation. The efforts undertaken by the operators has had a significant impact on pipeline safety, nevertheless, during recent years we have seen a number of major high profile accidents. One can therefore ask how effective the pipeline integrity management systems and processes are. This paper will present one methodology 'The Pipeline System Operability Review' that can evaluate and rate the effectiveness of both the management systems and procedures, as well as the technical condition of the hardware. The result from the review can be used to compare the performance of different pipelines within one operating company, as well as benchmark with international best practices. (author)

  11. Operator licensing examiner standards

    International Nuclear Information System (INIS)

    The Operator Licensing Examiner Standards provide policy and guidance to NRC examiners and establish the procedures and practices for examining licensees and applicants for reactor operator and senior reactor operator licenses at power reactor facilities pursuant to Part 55 of Title 10 of the Code of Federal Regulations (10 CFR 55). The Examiner Standards are intended to assist NRC examiners and facility licensees to better understand the initial and requalification examination processes and to ensure the equitable and consistent administration of examinations to all applicants. These standards are not a substitute for the operator licensing regulations and are subject to revision or other internal operator licensing policy changes. Revision 7 was published in January 1993 and became effective in August 1993. Supplement 1 is being issued primarily to implement administrative changes to the requalification examination program resulting from the amendment to 10 CFR 55 that eliminated the requirement for every licensed operator to pass an NRC-conducted requalification examination as a condition for license renewal. The supplement does not substantially alter either the initial or requalification examination processes and will become effective 30 days after its publication is noticed in the Federal Register. The corporate notification letters issued after the effective date will provide facility licensees with at least 90 days notice that the examinations will be administered in accordance with the revised procedures

  12. Thermal Operating Modes

    International Nuclear Information System (INIS)

    Higher and lower temperature operating modes (e.g., above and below the boiling point of water) are alternative approaches to managing the heat produced by the radioactive decay of spent nuclear fuel. Current analyses indicate that a repository at the Yucca Mountain site is likely to comply with applicable safety standards regardless of the particular thermal operating mode. Both modes have potential advantages and disadvantages. With a higher temperature operating mode (HTOM), waste packages (WPs) can be placed closer together. This reduces the number of drifts, the required emplacement area, construction costs, and occupational risks to construction workers. In addition, the HTOM would minimize the amount of water that might contact the waste for hundreds of years after closure. On the other hand, higher temperatures introduce uncertainties in the understanding of the long-term performance of the repository because of uncertainties in the thermal effects on WP lifetime and the near-field environment around the drifts. A lower temperature operating mode (LTOM) has the potential to reduce uncertainties in long-term performance of the repository by limiting the effects of temperature on WP lifetime and on the near-field environment around the drifts. Depending on the combination of operating parameters, a LTOM could require construction of additional drifts, a larger emplacement area, increased construction costs, increased occupational risks to construction works, and a longer period of ventilation than a HTOM. The repository design for the potential Yucca Mountain site is flexible and can be constructed and operated in various operating modes to achieve specific technical objectives, accommodate future policy decisions, and use of new information. For example, the flexible design can be operated across a range of temperatures and can be tailored to achieve specific thermal requirements in the future. To accommodate future policy decisions, the repository can be

    This is a slide-based oral presentation given to the COG/IAEA: Fifth technical committee meeting on 'Exchange of operating experience of pressurized heavy water reactors' held in Mangalia, Romania on 7-10 September 1998. The plant states and operating conditions are defined as resulting from the consequences of a Licensing Basis Event occurrence. Three categories of important plant parameters are considered: A - directly associated with either the mechanical or instrumentation and control aspects of the Special Safety Systems; B - process conditions related to trip parameters; C - other parameters that effect outcome of an accident. In A category the following aspects were addressed: Instrument loop uncertainties and time lags and delays; Tank levels, pressures and chemistry; Valve operating times and characteristics; Pump performance; The number of redundant pieces of equipment. Relating to category B the process conditions implied in trip initiation parameters as they effect margin to trip are discussed and illustrated by the cases of pressurizer level, RB pressure, etc. Finally, in the last category, the parameters effecting accident outcome are considered, i.e. either process variables, or equipment associated with safety related or safety support systems. The following cases are analysed PHTS Isotopic/temperatures/flows, moderator outlet temperature, RCW/RSW temperature, number of available aux. boiler feedpumps. In connection with the plant states the following matters are analyzed: fueling; boiler tube leak; defect fuel; non-equilibrium core; shutdown and reduced power operation; two pump operation. Concerning the Safety Operating Envelope (SOE) the following issues are presented: OP and P (high level overview), supported by OM tests and surveillance, by taking into account the use Tech Specs for the future, the role of safety analysis, historical perspective at PLGS.

  14. Operational Dynamic Configuration Analysis

    Lai, Chok Fung; Zelinski, Shannon

    2010-01-01

    Sectors may combine or split within areas of specialization in response to changing traffic patterns. This method of managing capacity and controller workload could be made more flexible by dynamically modifying sector boundaries. Much work has been done on methods for dynamically creating new sector boundaries [1-5]. Many assessments of dynamic configuration methods assume the current day baseline configuration remains fixed [6-7]. A challenging question is how to select a dynamic configuration baseline to assess potential benefits of proposed dynamic configuration concepts. Bloem used operational sector reconfigurations as a baseline [8]. The main difficulty is that operational reconfiguration data is noisy. Reconfigurations often occur frequently to accommodate staff training or breaks, or to complete a more complicated reconfiguration through a rapid sequence of simpler reconfigurations. Gupta quantified a few aspects of airspace boundary changes from this data [9]. Most of these metrics are unique to sector combining operations and not applicable to more flexible dynamic configuration concepts. To better understand what sort of reconfigurations are acceptable or beneficial, more configuration change metrics should be developed and their distribution in current practice should be computed. This paper proposes a method to select a simple sequence of configurations among operational configurations to serve as a dynamic configuration baseline for future dynamic configuration concept assessments. New configuration change metrics are applied to the operational data to establish current day thresholds for these metrics. These thresholds are then corroborated, refined, or dismissed based on airspace practitioner feedback. The dynamic configuration baseline selection method uses a k-means clustering algorithm to select the sequence of configurations and trigger times from a given day of operational sector combination data. The clustering algorithm selects a simplified

This information is collected by the Office of Information Resources Management, from the Headquarters Staff of NRC's Office of Inspection and Enforcement, from NRC's Regional Offices, and from utilities. Since all of the data concerning operation of the units is provided by the utility operators less than two weeks after the end of the month, necessary corrections to published information are shown on the ERRATA page. This report is divided into three sections: the first contains monthly highlights and statistics for commercial operating units, and errata from previously reported data; the second is a compilation of detailed information on each unit, provided by NRC Regional Offices, IE Headquarters and the Utilities; and the third section is an appendix for miscellaneous information such as spent fuel storage capability, reactor years of experience and non-power reactors in the United States

  16. Aging and operation results

    International Nuclear Information System (INIS)

    The correlation between the different accelerated aging methods and operation reality has to be done with solid and representative elements in matter of tests as well as in operating experience. In 1990 in France, the first unit will be 13 years operating, there will be 34 units of 900 MW PWR and 18 units of 1300 MW PWR in operation. The total of experience will be equivalent to 400 reactor-years. Only computerised means permit to collect all corresponding events, to manage them and to draw a lot of conclusions. One describes these computerised applications explaining the different events collected, data input and interrogating possibilities. The first application, called ''events file'', records all important events in nuclear plants. For each of these events, an event reporting format is set up as soon as first informations are known and then is put into the file. An updating is performed when the event is better known and analyzed. Interrogating programs allow no specialist to access easily to this data bank. So it is possible to collect events of the same nature, of the same equipments or of the same systems. The second application called S.R.D.F. (fiability data bank system) collects all maintenance operations on certain mechanical and electrical equipment. These two computerized applications complete on another in the way they allow to do fiability and availability studies for some equipments or for some elements of a nuclear plant

  17. ITER-FEAT operation

    International Nuclear Information System (INIS)

    ITER is planned to be the first fusion experimental reactor in the world operating for research in physics and engineering. The first 10 years' operation will be devoted primarily to physics issues at low neutron fluence and the following 10 years' operation to engineering testing at higher fluence. ITER can accommodate various plasma configurations and plasma operation modes such as inductive high Q modes, long pulse hybrid modes, non-inductive steady-state modes, with large ranges of plasma current, density, beta and fusion power, and with various heating and current drive methods. This flexibility will provide an advantage for coping with uncertainties in the physics database, in studying burning plasmas, in introducing advanced features and in optimizing the plasma performance for the different programme objectives. Remote sites will be able to participate in the ITER experiment. This concept will provide an advantage not only in operating ITER for 24 hours per day but also in involving the world-wide fusion communities and in promoting scientific competition among the Parties.

  18. Operational cost drivers

    Science.gov (United States)

    Scholz, Arthur L.; Dickinson, William J.

    1988-01-01

    To be economically viable, the operations cost of launch vehicles must be reduced by an order of magnitude as compared to the Space Transportation System (STS). A summary of propulsion-related operations cost drivers derived from a two-year study of Shuttle ground operations is presented. Examples are given of the inordinate time and cost of launch operations caused by propulsion systems designs that did not adequately consider impacts on prelaunching processing. Typical of these cost drivers are those caused by central hydraulic systems, storable propellants, gimballed engines, multiple propellants, He and N2 systems and purges, hard starts, high maintenance turbopumps, accessibility problems, and most significantly, the use of multiple, nonintegrated RCS, OMS, and main propulsion systems. Recovery and refurbishment of SRBs have resulted in expensive crash and salvage operations. Vehicle system designers are encouraged to be acutely aware of these cost drivers and to incorporate solutions (beginning with the design concepts) to avoid business as usual and costs as usual.

  19. Automated emergency operating procedures

    International Nuclear Information System (INIS)

    This paper describes the development of a training tool for the symptom oriented emergency operating procedures used at the Laguna Verde Nuclear Power Plant. EOPs and operator training are intended to assist the operator for managing accident situations. A prototype expert system based on the EOPs has been developed for operator training. The demonstration expert system was developed using a commercial shell. The knowledge base consists of two parts. The specific operator actions to be executed for 5 selected accident sequences and the EOPs steps for the reactor pressure vessel control of the water level, pressure, and power. The knowledge is expressed in the form of IF-THEN production rules. A typical training session will display a set of conditions and will prompt the trainee to indicate the appropriate step to perform. This mode will guide the trainee through selected accident sequences. A second mode of the expert system will prompt the trainee for the current plant conditions and the expert system will respond with the EOPs which are required to be performed under these conditions. This allows the trainee to study What if situations

    International Nuclear Information System (INIS)

    The operation of an APPLE II based undulator beamline with all its polarization states (linear horizontal and vertical, circular and elliptical, and continous variation of the linear vector) requires an effective description allowing an automated calculation of gap and shift parameter as function of energy and operation mode. The extension of the linear polarization range from 0 to 180 deg. requires 4 shiftable magnet arrrays, permitting use of the APU (adjustable phase undulator) concept. Studies for a pure fixed gap APPLE II for the SLS revealed surprising symmetries between circular and linear polarization modes allowing for simplified operation.

The waste system at ORNL has been continually modified and updated to keep pace with the changing release requirements for radioactive wastes. Major upgrading projects are currently in progress. The operating record of ORNL waste operation has been excellent over many years. Recent surveillance of radioactivity in the Oak Ridge environs indicates that atmospheric concentrations of radioactivity were not significantly different from other areas in East Tennesseee. Concentrations of radioactivity in the Clinch River and in fish collected from the river were less than 4% of the permissible concentration and intake guides for individuals in the offsite environment. While some radioactivity was released to the environment from plant operations, the concentrations in all of the media sampled were well below established standards

The extension of the linear polarization range from 0 to 180° requires 4 shiftable magnet arrrays, permitting use of the APU (adjustable phase undulator) concept. Studies for a pure fixed gap APPLE II for the SLS revealed surprising symmetries between circular and linear polarization modes allowing for simplified operation. A semi-analytical model covering all types of APPLE II and its implementation will be presented.

  10. Injector operations at LAMPF

    International Nuclear Information System (INIS)

    The injector complex at LAMPF consists of three on-line 750-kV injectors which provide simultaneous H+ and H- beams for LAMPF production and an off-line 200-keV injector for ion source and beam diagnostic development studies. The present operation now entails a 500-μA/sub a/ H+ beam accelerated simultaneously with either a 6-μA/sub a/ unpolarized or 10-nA/sub a/ polarized H- beam. In order to obtain the low-beam spill required for the operation of the LAMPF accelerator, it has been necessary to increase the brightness of the high-intensity H+ beam. The operating experience and development work that has been carried out on all of these injectors to improve the quality and intensity of these beams will be presented. The details of the construction of the test stand injector and the development program planned for this injector will also be outlined

  11. Operations management for construction

    CERN Document Server

    March, Chris

    2009-01-01

    Students studying construction management and related subjects need to have a broad understanding of the major aspects of controlling the building processes. Operations Management for Construction is one of three textbooks (Business Organisation, Operations Management and Finance Control) written to systematically cover the field. Focusing on construction sites and operations which are challenging to run, Chris March explores issues such as the setting up of the site, the deciding of the methodology of construction, and the sequence of work and resourcing. As changing and increasing regulations affect the way sites are managed, he also considers the issues and methods of successful administering, safety, quality and environment. Finally, the contractor's responsibility to the environment, including relationships with third parties, selection of materials, waste management and sustainability is discussed. Chris March has a wealth of practical experience in the construction industry, as well as considerable exp...

  12. SSCL Commissioning and Operations

    International Nuclear Information System (INIS)

    The SSC, with an energy of 20 TeV/Beam, requires a sequence of individual accelerators of increasing energy in the injector chain. These are the Linac, Low Energy Booster, Medium Energy Booster, and High Energy Booster. Each accelerator system must be completed in sequence in order to provide beam to the next higher energy accelerator. The collider itself is comprised of ten sectors, each of which in terms of superconducting magnet bending strength, is equivalent to two HEB injectors. The completion of all injectors and collider sectors is required before stored beams can circulate in preparation for colliding beam operation. Four experimental halls are planned for the detector systems. Each major detector will be assembled in one of the halls by a world-wide collaboration of scientists. In addition, above ground facilities provide shops and test facilities for accelerator technical systems, superconducting magnet and materials research and development, and for detector assembly and operations. The purpose of this report is to present a plan for the sequential commissioning and operation of these individual accelerators and other technical facilities of the SSC. A central objective of this plan is to describe the activities at the SSCL that are not included as part of the construction project TPC, even though they occur during the overall project construction time-frame. Examples of such activities include the operation of general laboratory facilities and services not specifically related to construction, the operating costs for the individual accelerators in the injector chain once these facilities have been commissioned, and the costs of SSCL physics research groups. The Department of Energy has provided the following decision with regard to these operations categories for the SSCL

  13. Operating US power reactors

    In 1996, Nuclear Regulatory Authority of the Slovak Republic (NRA SR) ensured the Slovak Republic (SR) obligations with relation to the international agreements and with the SR membership in the IAEA.International co-operation has been ensured on the basis of the bilateral international agreements. With the Ministry of Foreign Affairs co-operation, the SR fulfilled its financial obligations to this organization in due time and in the full scope. Representing Central and Eastern Europe interest in the Board of Governors, the SR participation in the highest executive in the highest executive authority was finished in 1996.The Board of Governors Vice-chairman position was executed by NRA SR Chairman. 5 national and 6 regional technical co-operation and assistance projects were realized in 1996. 12 organizations participated in these projects and accordingly 104 experts took part in training programmes, scientific visits or as the mission members abroad. Besides, Slovak experts participated at work of technical advisory and consultation groups with the significant assistance. In the framework of IAEA co-operation, the SR was visited by 11 expert missions formed by 28 experts from 19 countries including IAEA. Slovak organizations, namely institutes of the Academy of Sciences, Slovak research centres and universities participated in IAEA scientific and research activities through NRA SR. 15 scientific contracts in total were approved and realized and these contracts are utilized as supplementary financing of the own scientific and research projects. Other international co-operation and regional co-operation activities of the NRA SR in 1996 are reviewed

  15. GNF2 Operating Experience

    International Nuclear Information System (INIS)

    GNF's latest generation fuel product, GNF2, is designed to deliver improved nuclear efficiency, higher bundle and cycle energy capability, and more operational flexibility. But along with high performance, our customers face a growing need for absolute fuel reliability. This is driven by a general sense in the industry that LWR fuel reliability has plateaued. Too many plants are operating with fuel leakers, and the impact on plant operations and operator focus is unacceptable. The industry has responded by implementing an INPO-coordinated program aimed at achieving leaker-free reliability by 2010. One focus area of the program is the relationship between fuel performance (i.e., duty) and reliability. The industry recognizes that the right balance between performance and problem-free fuel reliability is critical. In the development of GNF2, GNF understood the requirement for a balanced solution and utilized a product development and introduction strategy that specifically addressed reliability: evolutionary design features supported by an extensive experience base; thoroughly tested components; and defense-in-depth mitigation of all identified failure mechanisms. The final proof test that the balance has been achieved is the application of the design, initially through lead use assemblies (LUAs), in a variety of plants that reflect the diversity of the BWR fleet. Regular detailed surveillance of these bundles provides the verification that the proper balance between performance and reliability has been achieved. GNF currently has GNF2 lead use assemblies operating in five plants. Included are plants that have implemented extended power up-rates, plants on one and two-year operating cycles, and plants with and without NobleChemTM and zinc injection. The leading plant has undergone three pool-side inspections outages to date. This paper reviews the actions taken to insure GNF2's reliability, and the lead use assembly surveillance data accumulated to date to validate

    Hall, Dennis E.; Scherrer, Deborah K.; Sventek, Joseph S.

    1980-05-01

    Significant progress toward disentangling computing environments from their under lying operating systern has been made. An approach is presented that achieves inter-system uniformity at all three levels of user interface - virtual machine, utilities, and command language. Under specifiable conditions, complete uniformity is achievable without disturbing the underlying operating system. The approach permits accurate computation of the cost to move both people and software to a new system. The cost of moving people is zero, and the cost of moving software is equal to the cost of implementing a virtual machine. Efficiency is achieved through optimization of the primitive functions.

    Methods of using specific operational charge and discharge parameters to extend the life of alkaline batteries are disclosed. The methods can be used with any commercial primary or secondary alkaline battery, as well as with newer alkaline battery designs, including batteries with flowing electrolyte. The methods include cycling batteries within a narrow operating voltage window, with minimum and maximum cut-off voltages that are set based on battery characteristics and environmental conditions. The narrow voltage window decreases available capacity but allows the batteries to be cycled for hundreds or thousands of times.

    2016-08-01

    Appendectomy has been the standard of care for appendicitis since the late 1800s, and remains one of the most common operations performed in children. The advent of data-driven medicine has led to questions about every aspect of the operation-whether appendectomy is even necessary, when it should be performed (timing), how the procedure is done (laparoscopic variants versus open and irrigation versus no irrigation), length of hospital stay, and antibiotic duration. The goal of this analysis is to review the current status of, and available data regarding, the surgical management of appendicitis in children. PMID:27521710

  1. Cohomological vertex operators

    CERN Document Server

    Viña, Andrés

    2016-01-01

    Given a Calabi-Yau manifold and considering the $B$-branes on it as objects in the derived category of coherent sheaves, we identify the vertex operators for strings between two branes with elements of the cohomology groups of Ext sheaves. We define the correlation functions for these general vertex operators. Strings stretching between two coherent sheaves are studied as homological extensions of the corresponding branes. In this context, we relate strings between different pairs of branes when there are maps between these branes. We also interpret some strings with ghost number $k$ as obstructions for lifts or extensions of strings with ghost number $k-1$.

    Exner, Pavel

    2012-01-01

    We discuss ways in which momentum operators can be introduced on an oriented metric graph. A necessary condition appears to the balanced property, or a matching between the numbers of incoming and outgoing edges; we show that a graph without an orientation, locally finite and at most countably infinite, can made balanced oriented \\emph{iff} the degree of each vertex is even. On such graphs we construct families of momentum operators; we analyze their spectra and associated unitary groups. We also show that the unique continuation principle does not hold here.

  14. Dam safety operating guidelines

    International Nuclear Information System (INIS)

    As part of Ontario Hydro's dam structure assessment program, the hydraulic design review of several river systems has revealed that many existing dam sites, under current operating procedures, would not have sufficient discharge capacity to pass the Inflow Design Flood (IDF) without compromising the integrity of the associated structures. Typical mitigative measures usually considered in dealing with these dam sites include structural alterations, emergency action plans and/or special operating procedures designed for extreme floods. A pilot study was carried out for the Madawaska River system in eastern Ontario, which has seven Ontario Hydro dam sites in series, to develop and evaluate the effectiveness of the Dam Safety Operating Guidelines (DSOG). The DSOG consist of two components: the flood routing schedules and the minimum discharge schedules, the former of which would apply in the case of severe spring flood conditions when the maximum observed snowpack water content and the forecast rainfall depth exceed threshold values. The flood routing schedules would identify to the operator the optimal timing and/or extent of utilizing the discharge facilities at each dam site to minimize the potential for dam failures cased by overtopping anywhere in the system. It was found that the DSOG reduced the number of structures overtopped during probable maximum flood from thirteen to four, while the number of structures that could fail would be reduced from seven to two. 8 refs., 4 figs., 3 tabs

  19. Fast Fuzzy Arithmetic Operations

    Science.gov (United States)

    Hampton, Michael; Kosheleva, Olga

    1997-01-01

    In engineering applications of fuzzy logic, the main goal is not to simulate the way the experts really think, but to come up with a good engineering solution that would (ideally) be better than the expert's control, In such applications, it makes perfect sense to restrict ourselves to simplified approximate expressions for membership functions. If we need to perform arithmetic operations with the resulting fuzzy numbers, then we can use simple and fast algorithms that are known for operations with simple membership functions. In other applications, especially the ones that are related to humanities, simulating experts is one of the main goals. In such applications, we must use membership functions that capture every nuance of the expert's opinion; these functions are therefore complicated, and fuzzy arithmetic operations with the corresponding fuzzy numbers become a computational problem. In this paper, we design a new algorithm for performing such operations. This algorithm is applicable in the case when negative logarithms - log(u(x)) of membership functions u(x) are convex, and reduces computation time from O(n(exp 2))to O(n log(n)) (where n is the number of points x at which we know the membership functions u(x)).

  20. Energy Operations Policy

    International Nuclear Information System (INIS)

    The document sets out the operational role of the Bank in this sector and establishes the overall framework for the Bank's activities. This new Policy replaces and updates the Natural Resources Operations Policy and the Energy Operations Policy approved by the Board of Directors in 1999 and 2000, respectively, combining the two spheres of activity into one comprehensive policy. Specifically, this Policy builds on past policies and complements more closely new regional and global energy initiatives now being implemented by national and international bodies. The Policy particularly mandates the Bank to increase its support for energy efficiency and renewable energy, corporate governance and transparency, and to refine its activities in other areas based on lessons learned and evolving best international practices. The Policy encompasses all activities in energy conversion including: demand side performance, power generation, transmission, distribution and supply, the entire oil and gas cycle from production to transportation, refining, and distribution and coal mining. The Policy will guide the Bank in its direct investment operations and, as expressly provided, in its investments through financial intermediaries

  2. Operator/contractor relationships

    International Nuclear Information System (INIS)

    In May 1988, Shell Western E and P Inc. (SWEPI) and partners Elf Aquitaine Petroleum and Conoco Inc. signed a letter of intent with Canadian Marine Drilling Ltd. (Canmar) for provision of exploratory drilling and marine services on leases in OCS Lease Sale 109 in the Chukchi Sea, Alaska. The 5450 blocks offered in the remote sale area west of Point Barrow ranged from 3 to 240 miles (5 to 380 km) offshore in water depths from 26 to 263 feet (8 to 80 m). The principal interest tracts were at least 75 miles (120 km) offshore and north of 70 degrees N latitude. The remoteness and total lack of any oilfield infrastructure required considerable planning and coordination between Operator and Contractor in order to carry out the three-year drilling program efficiently and safely in an environmentally harsh and, at the same time, sensitive area. SWEPI and Canmar developed a close working relationship from the start of the project through a number of participative approaches to the problems that had to be solved. This paper reports that these included strong reliance on operational planning meetings, post-season analyses, and an overall emphasis on the teamwork required of both parties to carry out the first-ever drilling program in the Chukchi Sea. This approach led to a very successful operation for both parties and emphasizes the positive benefits achievable when Operator and Contractor work as a team

  19. Intelligent Potroom Operation

    Energy Technology Data Exchange (ETDEWEB)

    Jan Berkow; Larry Banta

    2003-07-29

    The Intelligent Potroom Operation project focuses on maximizing the performance of an aluminum smelter by innovating components for an intelligent manufacturing system. The Intelligent Potroom Advisor (IPA) monitors process data to identify reduction cells exhibiting behaviors that require immediate attention. It then advises operational personnel on those heuristic-based actions to bring the cell back to an optimal operating state in order to reduce the duration and frequency of substandard reduction cell performance referred to as ''Off-Peak Modes'' (OPMs). Techniques developed to identify cells exhibiting OPMs include the use of a finite element model-based cell state estimator for defining the cell's current operating state via advanced cell noise analyses. In addition, rule induction was also employed to identify statistically significant complex behaviors that occur prior to OPMs. The intelligent manufacturing system design, concepts and formalisms developed in this project w ere used as a basis for an intelligent manufacturing system design. Future research will incorporate an adaptive component to automate continuous process improvement, a technology platform with the potential to improve process performance in many of the other Industries of the Future applications as well.

  20. PSA in operator training

    International Nuclear Information System (INIS)

    The systematic approach to training is internationally accepted as the best method to achieve and maintain the qualification and competence of power plant personnel and to guarantee the quality of their training. Following the recommendations and guidelines of international organisations competent in the field, TECNATOM SA has developed projects based on the systematic approach to training for all Spanish nuclear power plants. One of the latest projects was the systematic approach to training developed for the operation personnel of ASCO Nuclear Power Plant. In this case, certain results of the Probabilistic Safety Analysis (PSA) which complement the systematic safety and reliability criteria of the systematic approach to training process have been incorporated in the traditional processes of work and task analysis and training plan design. This incorporation provides the training manager with additional criteria based not only on safety aspects obtained through the statistical treatment of considerations of skilled technical personnel (operators, operation chief supervisors, etc), but also on the independent criterion of the PSA. The inclusion of this approach basically affects all systematics in two of its stages: During the selection process of operating practices in SMR or SGI, the possible scenarios have been associated with all those situations where human actions which lead to an initiating event or human actions to mitigate an initiating event, may take place, as defined in the PSA. During the scenario development process, the instruments involved in the performance of human actions which originate or mitigate an event taking place have been identified. This pakes it possible to reconcile the scenario event sequence with the sequence considered in the PSA study, as the most likely to provoke a more serious accident. The incorporation of these PSA results contributes to the strengthening of safety aspects in training in an objective way, and confirms that

    The fourteen dish white cliffs solar power station area is remote and subject to extreme environmental conditions, solution of the associated problems required careful and thoughtful attention and the application of resources. Notwithstanding the wide range and harshness of conditions, the difficulties caused by remoteness and the lack of a technological base and the need for relatively rapid demonstration of success, the project has had a very positive outcome. Qualitative and quantitative information and lessons are now available to enable considerable simplifications to be made for a new system, reducing both hardware and operation and maintenance costs. Experience and lessons are presented, particularly in relation to: system performance in various environmental conditions; design philosophies for collectors, the array, control systems, engine and plant; operation and maintenance strategies and cost reducing possibilities. Experience so far gives encouragement for the future of such paraboloidal dish systems in appropriate areas.

  7. Tevatron lower temperature operation

    International Nuclear Information System (INIS)

    This year saw the completion of three accelerator improvement projects (AIP) and two capital equipment projects pertaining to the Tevatron cryogenic system. The projects result in the ability to operate the Tevatron at lower temperature, and thus higher energy. Each project improves a subsystem by expanding capabilities (refrigerator controls), ensuring reliability (valve box, subatmospheric hardware, and compressor D), or enhancing performance (cold compressors and coldbox II). In January of 1994, the Tevatron operated at an energy of 975 GeV for the first time. This was the culmination, of many years of R ampersand D, power testing in a sector (one sixth) of the Tevatron, and final system installation during the summer of 1993. Although this is a modest increase in energy, the discovery potential for the Top quark is considerably improved

    1993-01-01

    C Language Integrated Production System (CLIPS), a NASA-developed expert systems program, is used by American Airlines for three purposes: as a rapid prototyping tool; to develop production prototypes; and to develop production application. An example of the latter is CLIPS' use in "Hub S1AAshing," a knowledge based system that recommends contingency plans when severe schedule reductions must be made. Hub S1AAshing has replaced a manual, labor intensive process. It saves time and allows Operations Control Coordinators to handle more difficult situations. Because the system assimilates much of the information necessary to facilitate educated decision making, it minimizes negative impact in situations where it is impossible to operate all flights.

  11. Hurricane slams gulf operations

    International Nuclear Information System (INIS)

    This paper reports that reports of damage by Hurricane Andrew escalated last week as operators stepped up inspections of oil and gas installations in the Gulf of Mexico. By midweek, companies operating in the gulf and South Louisiana were beginning to agree that earlier assessments of damage only scratched the surface. Damage reports included scores of lost, toppled, or crippled platforms, pipeline ruptures, and oil slicks. By midweek the U.S. coast Guard had received reports of 79 oil spills. Even platforms capable of resuming production in some instances were begin curtailed because of damaged pipelines. Offshore service companies the another 2-4 weeks could be needed to fully assess Andrew's wrath. Lack of personnel and equipment was slowing damage assessment and repair

  12. Cyclone incinerator: operating experience

    International Nuclear Information System (INIS)

    The cyclone incinerator, developed at Mound in the mid to late 1970's, has proven to be a valuable tool for the volume reduction of the plant's combustible radioactive wastes. The incinerator has affected a significant reduction in Mound's offsite waste shipping requirements. More than 27 tons of plutonium-contaminated wastes have been incinerated in the system at volume reduction factors of greater than 95%. Moreover, the extreme simplicity of the system in principle, design, components, and operation has resulted in extremely low maintenance cost and real plant cost savings in waste handling and disposal over the past several years. The cyclone incinerator has more potential plant users than available operating time. In addition to burning dry solids, incineration feasibility has been demonstrated for wastes presenting special disposal problems to the plant. These wastes include combustible liquids, scintillation vials, and tritium contaminated dry solid wastes

  20. Explicit Fourier wavefield operators

    Science.gov (United States)

    Ferguson, R. J.; Margrave, G. F.

    2006-04-01

    Explicit wavefield extrapolators are based on direct analytic mathematical formulae that express the output as an extrapolation operator acting on the input, while implicit methods usually require the calculation of the numerical inverse of a matrix to obtain the output. Typically, explicit methods are faster than implicit methods, and they often give more insight into the physics of the wave propagation, but they often suffer from instability. Four different explicit extrapolators based on Fourier theory are presented and analysed. They are: PS (ordinary phase shift), GPSPI (generalized phase shift plus interpolation), NSPS (non-stationary phase shift) and SNPS (symmetric non-stationary phase shift). A formal proof is given that NSPS in a direction orthogonal to the velocity gradient is the mathematical adjoint process to GPSPI in the opposite direction. This motivates the construction of SNPS that combines NSPS and GPSPI in a symmetric fashion. This symmetry (under interchange of input and output lateral coordinates) is required by reciprocity arguments. PS and SNPS are symmetric while NSPS and GPSPI are not. A numerical stability study using SVD (singular value decomposition) shows that all of these extrapolators can become unstable for strong lateral velocity gradients. Unstable operators allow amplitudes to grow non-physically in a recursion. Stability is enhanced by introducing a small (~3 per cent) imaginary component to the velocities. This causes a numerical attenuation that tends to stabilize the operators but does not address the cause of the instability. For the velocity model studied (a very challenging case) GPSPI and NSPS have exactly the same instability while SNPS is always more stable. Instability manifests in a complicated way as a function of extrapolation step size, frequency, velocity gradient, and strength of numerical attenuation. The SNPS operator can be stabilized over a wide range of conditions with considerably less attenuation than is

  8. 88-Inch Cyclotron operations

    International Nuclear Information System (INIS)

    The 88-Inch Cyclotron, operated by the Nuclear Science Division, provides a large fraction of the beam time that is used by Division scientists. Variable energy high resolution beams from hydrogen through argon are produced and used for studies of nuclear structure and nuclear reaction mechanisms. The cyclotron is also the Laboratory's major source of medical isotopes and its only source of polarized proton and deuteron beams. Ions as heavy as 40Ar can be accererated to the Coulomb barrier of 5 MeV/nucleon, while lighter heavy ions can reach 20-30 MeV/nucleon. The cyclotron thus operates in the important transition region between low and high energies: 10-30 MeV/nucleon. As a national accelerator laboratory the 88-Inch Cyclotron is used extensively by outside groups from many institutions in the US and abroad. The 88-Inch Cyclotron also plays a significant educational role. In 1983 twelve graduate students from the University of California at Berkeley employed this facility in their research toward the Ph.D. degree. Five students received their doctorates from UCB in 1983 for research done at the cyclotron. Eleven graduate students from other universities participated in research at the cyclotron. The cyclotron now operates 14 1/2 eight hour shifts per week with one additional shift for maintenance at the beginning of the week and one half shift for shutdown for the weekend. It was operated for 20 shifts per week until October 1981 when increased power rates and budget limitations made the reduction in running time necessary. Several improvement programs are ongoing

  9. Operation and development 1999

    International Nuclear Information System (INIS)

    This issue of the Technical Report on the Accelerators describes the operations for physics experiments and beam tests, various technical improvements and ongoing projects during the year 1999. As usual, the first chapter reports on the standard operation of GANIL with stable ions, with analysis of the beam time distribution and statistics, including failures. A major project was the production and subsequent acceleration, over a long period of time, of an intense 58Ni11+ beam produced using the MIVOC method, which contributed strongly to the discovery of the doubly-magic 48Ni element. The renovation and development program (Chapter 2), including methods for producing metallic ion beams, gathered speed thanks to the completion of SPIRAL. A large share of these projects were high-intensity oriented. This trend also obviously applies to projects directly linked to the THI operation. In a special test, a 1.3 x 1013 pps 13C beam (later raised to 2 x 1013 pps for several hours) was accelerated and extracted from SSC2 at an energy of 75 MeV/n. Simultaneously, comparisons were made between simulations and beam test results for a clearer understanding of space charge effects on accelerator transmission efficiency. Chapter 3 covers the THI related projects. The final chapter deals with IRRSUD. This project, which is funded and on the way to completion, uses low energy beams delivered by the two injector cyclotrons for industrial applications and research, such as nano-technologies and simulation of defects in solids.

  12. Phenix operating experience

    International Nuclear Information System (INIS)

    The fast breeder reactor equipping the PHENIX plant has been in operation for 17 years. Apart from electricity production, operation of the 250 MWe reactor had the following positive results: - it proved that such a reactor could be operated without major difficulties and with a high energy availability factor, - it provided opportunities for fast breeder fuel optimization, - it yielded a certain number of safety lessons of interest in the context of breeder development work. The incidents which have occurred in recent years will be discussed in detail, with attention to the lessons drawn. After reviewing these different events, we shall present various surveys and structural provisions implemented with a view to confirming reactor safety and enhancing certain aspects of it, particularly in the light of the general lessons learned from the Three Mile Island and Chernobyl accidents. Examples will be discussed, such as the tests and inspections carried out during the second ten-yearly shutdown in 1989 (general overhaul), and the definition of procedures to be adopted in case of accidents at the limits or beyond the design basis situations.

  15. Improving operating room schedules.

    Science.gov (United States)

    Li, Fei; Gupta, Diwakar; Potthoff, Sandra

    2016-09-01

    Operating rooms (ORs) in US hospitals are costly to staff, generate about 70 % of a hospital's revenues, and operate at a staffed-capacity utilization of 60-70 %. Many hospitals allocate blocks of OR time to individual or groups of surgeons as guaranteed allocation, who book surgeries one at a time in their blocks. The booking procedure frequently results in unused time between surgeries. Realizing that this presents an opportunity to improve OR utilization, hospitals manually reschedule surgery start times one or two days before each day of surgical operations. The purpose of rescheduling is to decrease OR staffing costs, which are determined by the number of concurrently staffed ORs. We formulate the rescheduling problem as a variant of the bin-packing problem with interrelated items, which are the surgeries performed by the same surgeon. We develop a lower bound (LB) construction algorithm and prove that the LB is at least (2/3) of the optimal staffing cost. A key feature of our approach is that we allow hospitals to have two shift lengths. Our analytical results form the basis of a branch-and-bound algorithm, which we test on data obtained from three hospitals. Experiments show that rescheduling saves significant staffing costs.

    The fast breeder reactor equipping the PHENIX plant has been in operation for 17 years. Apart from electricity production, operation of the 250 MWe reactor had the following positive results: - it proved that such a reactor could be operated without major difficulties and with a high energy availability factor, - it provided opportunities for fast breeder fuel optimization, - it yielded a certain number of safety lessons of interest in the context of breeder development work. The incidents which have occurred in recent years will be discussed in detail, with attention to the lessons drawn. After reviewing these different events, we shall present various surveys and structural provisions implemented with a view to confirming reactor safety and enhancing certain aspects of it, particularly in the light of the general lessons learned from the Three Mile Island and Chernobyl accidents. Examples will be discussed, such as the tests and inspections carried out during the second ten-yearly shutdown in 1989 (general overhaul), and the definition of procedures to be adopted in case of accidents at the limits or beyond the design basis situations

  17. ILC Operating Scenarios

    International Nuclear Information System (INIS)

    The ILC Technical Design Report documents the design for the construction of a linear collider which can be operated at energies up to 500 GeV. This report summarizes the outcome of a study of possible running scenarios, including a realistic estimate of the real time accumulation of integrated luminosity based on ramp-up and upgrade processes. The evolution of the physics outcomes is emphasized, including running initially at 500 GeV, then at 350 GeV and 250 GeV. The running scenarios have been chosen to optimize the Higgs precision measurements and top physics while searching for evidence for signals beyond the standard model, including dark matter. In addition to the certain precision physics on the Higgs and top that is the main focus of this study, there are scientific motivations that indicate the possibility for discoveries of new particles in the upcoming operations of the LHC or the early operation of the ILC. Follow-up studies of such discoveries could alter the plan for the centre-of-mass collision energy of the ILC and expand the scientific impact of the ILC physics program. It is envisioned that a decision on a possible energy upgrade would be taken near the end of the twenty year period considered in this report.

    International Nuclear Information System (INIS)

    The research program has attempted to determine low environmental agents, especially ionizing radiation, interact with DNA and how the cells respond to the resulting damage. The focus has been on the spectrum of damage generated in DNA, the kinds of damage that can be repaired, and the mechanisms of repair. The effects of radioprotective agents and certain sensitizing conditions on breakage of DNA in bacterial cells by ionizing radiation, and mechanisms of enzymatic excision of pyrimidine dimers and other DNA adducts have been studied

    These studies have focussed on agents which cause damage to DNA leading to inhibition of DNA synthesis or faulty DNA replication or repair. The overall goal of this project has been to understand how environmental agents interact with the DNA of cells and how cells cope with any resulting damage. In particular we have been concerned with the nature of the repair systems involved in restoration of damaged DNA and the cellular responses to radiation or chemical damage

  6. Operator algebras and topology

    International Nuclear Information System (INIS)

    These notes, based on three lectures on operator algebras and topology at the 'School on High Dimensional Manifold Theory' at the ICTP in Trieste, introduce a new set of tools to high dimensional manifold theory, namely techniques coming from the theory of operator algebras, in particular C*-algebras. These are extensively studied in their own right. We will focus on the basic definitions and properties, and on their relevance to the geometry and topology of manifolds. A central pillar of work in the theory of C*-algebras is the Baum-Connes conjecture. This is an isomorphism conjecture, as discussed in the talks of Luck, but with a certain special flavor. Nevertheless, it has important direct applications to the topology of manifolds, it implies e.g. the Novikov conjecture. In the first chapter, the Baum-Connes conjecture will be explained and put into our context. Another application of the Baum-Connes conjecture is to the positive scalar curvature question. This will be discussed by Stephan Stolz. It implies the so-called 'stable Gromov-Lawson-Rosenberg conjecture'. The unstable version of this conjecture said that, given a closed spin manifold M, a certain obstruction, living in a certain (topological) K-theory group, vanishes if and only M admits a Riemannian metric with positive scalar curvature. It turns out that this is wrong, and counterexamples will be presented in the second chapter. The third chapter introduces another set of invariants, also using operator algebra techniques, namely L2-cohomology, L2-Betti numbers and other L2-invariants. These invariants, their basic properties, and the central questions about them, are introduced in the third chapter. (author)

  7. Categorizing operational radioactive wastes

    International Nuclear Information System (INIS)

    The primary objective of this publication is to improve communications among waste management professionals and Member States relative to the properties and status of radioactive waste. This is accomplished by providing a standardized approach to operational waste categorization using accepted industry practices and experience. It is a secondary objective to draw a distinction between operational waste categorization and waste disposal classification. The approach set forth herein is applicable to waste generation by mature (major, advanced) nuclear programmes, small-to-medium sized nuclear programmes, and programmes with waste from other nuclear applications. It can be used for planning, developing or revising categorization methodologies. For existing categorization programmes, the approach set forth in this publication may be used as a validation and evaluation tool for assessing communication effectiveness among affected organizations or nations. This publication is intended for use by waste management professionals responsible for creating, implementing or communicating effective categorization, processing and disposal strategies. For the users of this publication, it is important to remember that waste categorization is a communication tool. As such, the operational waste categories are not suitable for regulatory purposes nor for use in health and safety evaluations. Following Section 1 (Introduction) Section 2 of this publication defines categorization and its relationship to existing waste classification and management standards, regulations and practices. It also describes the benefits of a comprehensive categorization programme and fundamental record considerations. Section 3 provides an overview of the categorization process, including primary categories and sub-categories. Sections 4 and 5 outline the specific methodology for categorizing unconditioned and conditioned wastes. Finally, Section 6 provides a brief summary of critical considerations that

    2001-07-01

    This issue of the Technical Report on the Accelerators describes the operations for physics experiments and beam tests, various technical improvements and ongoing projects during the year 1999. As usual, the first chapter reports on the standard operation of GANIL with stable ions, with analysis of the beam time distribution and statistics, including failures. A major project was the production and subsequent acceleration, over a long period of time, of an intense {sub 58}Ni{sup 11+} beam produced using the MIVOC method, which contributed strongly to the discovery of the doubly-magic {sub 48}Ni element. The renovation and development program (Chapter 2), including methods for producing metallic ion beams, gathered speed thanks to the completion of SPIRAL. A large share of these projects were high-intensity oriented. This trend also obviously applies to projects directly linked to the THI operation. In a special test, a 1.3 x 10{sup 13} pps {sub 13}C beam (later raised to 2 x 10{sup 13} pps for several hours) was accelerated and extracted from SSC2 at an energy of 75 MeV/n. Simultaneously, comparisons were made between simulations and beam test results for a clearer understanding of space charge effects on accelerator transmission efficiency. Chapter 3 covers the THI related projects. The final chapter deals with IRRSUD. This project, which is funded and on the way to completion, uses low energy beams delivered by the two injector cyclotrons for industrial applications and research, such as nano-technologies and simulation of defects in solids.

    2009-06-11

    The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

  10. CMS analysis operations

    International Nuclear Information System (INIS)

    During normal data taking CMS expects to support potentially as many as 2000 analysis users. Since the beginning of 2008 there have been more than 800 individuals who submitted a remote analysis job to the CMS computing infrastructure. The bulk of these users will be supported at the over 40 CMS Tier-2 centres. Supporting a globally distributed community of users on a globally distributed set of computing clusters is a task that requires reconsidering the normal methods of user support for Analysis Operations. In 2008 CMS formed an Analysis Support Task Force in preparation for large-scale physics analysis activities. The charge of the task force was to evaluate the available support tools, the user support techniques, and the direct feedback of users with the goal of improving the success rate and user experience when utilizing the distributed computing environment. The task force determined the tools needed to assess and reduce the number of non-zero exit code applications submitted through the grid interfaces and worked with the CMS experiment dashboard developers to obtain the necessary information to quickly and proactively identify issues with user jobs and data sets hosted at various sites. Results of the analysis group surveys were compiled. Reference platforms for testing and debugging problems were established in various geographic regions. The task force also assessed the resources needed to make the transition to a permanent Analysis Operations task. In this presentation the results of the task force will be discussed as well as the CMS Analysis Operations plans for the start of data taking.

    The IBRD Operational Decision Framework in this document is an expansion of an emerging general risk management framework under development by an interagency working group. It provides the level of detail necessary to develop a general Consequence Management Guidance Document for biological contamination remediation and restoration. It is the intent of this document to support both wide area and individual site remediation and restoration activities. This product was initiated as a portion of the IBRD Task 1 Systems Analysis to aid in identification of wide area remediation and restoration shortcomings and gaps. The draft interagency general risk management framework was used as the basis for the analysis. The initial Task 1 analysis document expanded the draft interagency framework to a higher level of resolution, building on both the logic structure and the accompanying text explanations. It was then employed in a qualitative manner to identify responsible agencies, data requirements, tool requirements, and current capabilities for each decision and task. This resulted in identifying shortcomings and gaps needing resolution. Several meetings of a joint LLNL/SNL working group reviewed and approved the initial content of this analysis. At the conclusion of Task 1, work continued on the expanded framework to generate this Operational Decision Framework which is consistent with the existing interagency general risk management framework. A large LLNL task group met repeatedly over a three-month period to develop the expanded framework, coordinate the framework with the biological remediation checklist, and synchronize the logic with the Consequence Management Plan table of contents. The expanded framework was briefed at a large table top exercise reviewing the interagency risk management framework. This exercise had representation from major US metropolitan areas as well as national agencies. This product received positive comments from the participants. Upon

    Every year I take a PAP test, or a CTC as it is called in China. Last August, I was diagnosed with a uterine polypus. A "tumor?" Though a polypus is seldom cancerous, doctors insisted I have a biopsy. Were they concerned because I'm a foreigner or did they want to make money out of me? I preferred having the tumor removed rather than only a biopsy. They agreed. Before I knew it I was on the operation table after an electrocardiogram and a simple blood test.

    Today, computers fulfil a dazzling array of roles, a flexibility resulting from the great range of programs that can be run on them. A Science of Operations examines the history of what we now call programming, defined not simply as computer programming, but more broadly as the definition of the steps involved in computations and other information-processing activities. This unique perspective highlights how the history of programming is distinct from the history of the computer, despite the close relationship between the two in the 20th century. The book also discusses how the development of

    The ALMA (Atacama Large Millimeter/submillimeter Array) project is an international collaboration between Europe, East Asia and North America in cooperation with the Republic of Chile. The ALMA Array Operations Site (AOS) is located at Chajnantor, a plateau at an altitude of 5000 m in the Atacama desert in Chile, and the ALMA Operations Support Facility (OSF) is located near the AOS at an altitude of 2900 m. ALMA will consist of an array of 66 antennas, with baselines up to 16 km and state-of-the-art receivers that cover all the atmospheric windows up to 1 THz. An important component of ALMA is the compact array of twelwe 7-m and four 12-m antennas (the Atacama Compact Array, ACA), which will greatly enhance ALMA's ability to image extended sources. Construction of ALMA started in 2003 and will be completed in 2013. Commissioning started in January 2010 and Early Science Operations is expected to start during the second half of 2011. ALMA science operations is provided by the Joint ALMA Observatory (JAO) in Chile, and the three ALMA Regional Centers (ARCs) located in each ALMA region - Europe, North America and East Asia. ALMA observations will take place 24h per day, interrupted by maintenance periods, and will be done in service observing mode with flexible (dynamic) scheduling. The observations are executed in the form of scheduling blocks (SBs), each of which contains all information necessary to schedule and execute the observations. The default output to the astronomer will be pipeline-reduced images calibrated according to the calibration plan. The JAO is responsible for the data product quality. All science and calibration raw data are captured and archived in the ALMA archive, a distributed system with nodes at the OSF, the Santiago central office and the ARCs. Observation preparation will follow a Phase 1/Phase 2 process. During Phase 1, observation proposals will be created using software tools provided by the JAO and submitted for scientific and

    Many discretizations of integral equations and compact fixed point problems are collectively compact and strongly convergent in spaces of continuous functions. These properties not only lead to stable and convergent approximations but also can be used in the construction of fast multilevel algorithms. Recently the GMRES algorithm has become a standard coarse mesh solver. The purpose of this paper is to show how the special properties of integral operators and their approximations are reflected in the performance of the GMRES iteration and how these properties can be used to strengthen the norm in which convergence takes place. The authors illustrate these ideas with composite Gauss rules for integral equations on the unit interval.

    Deeper and more detailed knowledge as to how human operators such as pilots respond, singly and in groups, to demands on their performance which arise from technical systems will support the manipulation of such systems' design in order to accommodate the foibles of human behavior. Efforts to understand how self-autonomy impacts strategic behavior and such related issues as error generation/recognition/correction are still in their infancy. The present treatment offers both general and aviation-specific definitions of strategic behavior as precursors of prospective investigations.

    The EPOXI flight mission has been testing a new commercial system, Splunk, which employs data mining techniques to organize and present spacecraft telemetry data in a high-level manner. By abstracting away data-source specific details, Splunk unifies arbitrary data formats into one uniform system. This not only reduces the time and effort for retrieving relevant data, but it also increases operational visibility by allowing a spacecraft team to correlate data across many different sources. Splunk's scalable architecture coupled with its graphing modules also provide a solid toolset for generating data visualizations and building real-time applications such as browser-based telemetry displays.

    We extend the theory of distributional kernel operators to a framework of generalized functions, in which they are replaced by integral kernel operators. Moreover, in contrast to the distributional case, we show that these generalized integral operators can be composed unrestrictedly. This leads to the definition of the exponential, and more generally entire functions, of a subclass of such operators.

  5. Improving operational plume forecasts

    Balcerak, Ernie

    2012-04-01

    Forecasting how plumes of particles, such as radioactive particles from a nuclear disaster, will be transported and dispersed in the atmosphere is an important but computationally challenging task. During the Fukushima nuclear disaster in Japan, operational plume forecasts were produced each day, but as the emissions continued, previous emissions were not included in the simulations used for forecasts because it became impractical to rerun the simulations each day from the beginning of the accident. Draxler and Rolph examine whether it is possible to improve plume simulation speed and flexibility as conditions and input data change. The authors use a method known as a transfer coefficient matrix approach that allows them to simulate many radionuclides using only a few generic species for the computation. Their simulations work faster by dividing the computation into separate independent segments in such a way that the most computationally time consuming pieces of the calculation need to be done only once. This makes it possible to provide real-time operational plume forecasts by continuously updating the previous simulations as new data become available. They tested their method using data from the Fukushima incident to show that it performed well. (Journal of Geophysical Research-Atmospheres, doi:10.1029/2011JD017205, 2012)

    In this present days and age, there are increasing needs for companies to monitor application and infrastructure health. Apart from having proactive measures to secure their application and infrastructure, many see monitoring dashboards as crucial investment in disaster preparedness. As companies struggle to find the best solution to cater for their needs and interest for monitoring their application and infrastructure's health, this paper summarizes the studies made on several known off-the-shelf operations dashboard and in-house developed dashboard. A few criteria of good dashboard are collected from previous studies carried out by several researchers and rank them according to importance and business needs. The finalized criteria that will be discussed in later sections are data visualization, performance indicator, dashboard personalization, audit capability and alert/ notification. Comparative studies between several popular dashboards were then carried out to determine whether they met these criteria that we derived from the first exercise. The findings hopefully can be used to educate and provide an overview of selecting the best IT application and infrastructure operations dashboard that suit business needs, thus become the main contribution of this paper.

  7. ATLAS solenoid operates underground

    2006-01-01

    A new phase for the ATLAS collaboration started with the first operation of a completed sub-system: the Central Solenoid. Teams monitoring the cooling and powering of the ATLAS solenoid in the control room. The solenoid was cooled down to 4.5 K from 17 to 23 May. The first current was established the same evening that the solenoid became cold and superconductive. 'This makes the ATLAS Central Solenoid the very first cold and superconducting magnet to be operated in the LHC underground areas!', said Takahiko Kondo, professor at KEK. Though the current was limited to 1 kA, the cool-down and powering of the solenoid was a major milestone for all of the control, cryogenic, power and vacuum systems-a milestone reached by the hard work and many long evenings invested by various teams from ATLAS, all of CERN's departments and several large and small companies. Since the Central Solenoid and the barrel liquid argon (LAr) calorimeter share the same cryostat vacuum vessel, this achievement was only possible in perfe...

  8. Planck-suppressed operators

    International Nuclear Information System (INIS)

    We show that the recent Planck limits on primordial non-Gaussianity impose strong constraints on light hidden sector fields coupled to the inflaton via operators suppressed by a high mass scale Λ. We study a simple effective field theory in which a hidden sector field is coupled to a shift-symmetric inflaton via arbitrary operators up to dimension five. Self-interactions in the hidden sector lead to non-Gaussianity in the curvature perturbations. To be consistent with the Planck limit on local non-Gaussianity, the coupling to any hidden sector with light fields and natural cubic couplings must be suppressed by a very high scale Λ > 105H. Even if the hidden sector has Gaussian correlations, nonlinearities in the mixing with the inflaton still lead to non-Gaussian curvature perturbations. In this case, the non-Gaussianity is of the equilateral or orthogonal type, and the Planck data requires Λ > 102H

  9. South African Airborne Operations

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Airborne operations entail the delivery of ground troops and their equipment by air to their area of operations. They can also include the subsequent support of these troops and their equipment by air. Historically, and by definition, this would encompass delivery by fixed-wing powered aircraft, by glider, by parachute or by helicopter. Almost any troops can be delivered by most of these means. However, the technical expertise and physical as well as psychological demands required by parachuting have resulted in specialist troops being selected and trained for this role. Some of the material advantages of using parachute troops, or paratroops, are: the enormous strategic reach provided by the long-distance transport aircraft used to convey them; the considerable payload which these aircraft are capable of carrying; the speed with which the parachute force can deploy; and the fact that no infrastructure such as airfields are required for their arrival. Perhaps most attractively to cash-strapped governments, the light equipment scales of parachute units’ makes them economical to establish and maintain. There are also less tangible advantages: the soldiers selected are invariably volunteers with a willingness or even desire to tackle challenges; their selection and training produces tough, confident and aggressive troops, psychologically geared to face superior odds and to function independently from other units; and their initiative and self-reliance combined with a high level of physical fitness makes them suitable for a number of different and demanding roles.

    As light time delays increase, the number of such situations in which crew autonomy is the best way to conduct the mission is expected to increase. However, there are significant open questions regarding which functions to allocate to ground and crew as the time delays increase. In situations where the ideal solution is to allocate responsibility to the crew and the vehicle, a second question arises: should the activity be the responsibility of the crew or an automated vehicle function? More specifically, we must answer the following questions: What aspects of mission operation responsibilities (Plan, Train, Fly) should be allocated to ground based or vehicle based planning, monitoring, and control in the presence of significant light-time delay between the vehicle and the Earth?How should the allocated ground based planning, monitoring, and control be distributed across the flight control team and ground system automation? How should the allocated vehicle based planning, monitoring, and control be distributed between the flight crew and onboard system automation?When during the mission should responsibility shift from flight control team to crew or from crew to vehicle, and what should the process of shifting responsibility be as the mission progresses? NASA is developing a roadmap of capabilities for Autonomous Mission Operations for human spaceflight. This presentation will describe the current state of development of this roadmap, with specific attention to in-space inspection tasks that crews might perform with minimum assistance from the ground.

  11. FUGM hardware operation manual

    International Nuclear Information System (INIS)

    This manual describes the detector design features, performance, and operating characteristics of the Fugen reactor gate monitor for monitoring fresh and spent fuel transfers between the core and storage ponds. This system consists of two monitors located at each end of the transfer chute. The larger monitor contains two 3He tubes, two fission chambers, and two ion chambers. The smaller monitor, used for direction of motion redundancy, contains two ion chambers. All detectors provide information for identifying the type, fresh or spent UOX or MOX fuel, and direction of the fuel transfer. The gamma-ray and neutron detector (GRAND-3) electronics package supplies power to the radiation sensors and collects the radiation data for storage on a laptop computer. The system is designed to operate unattended with data collection by the inspectors occurring on 90-day time intervals. This manual also includes radiation data for the six types of fuel transfers and equipment transfers along with the direction of motion information collected during the installation at the Fugen reactor

  12. TFTR initial operations

    International Nuclear Information System (INIS)

    The Tokamak Fusion Test Reactor (TFTR) has operated since December 1982 with ohmically heated plasmas. Routine operation with feedback control of plasma current, position, and density has been obtained for plasmas with I/sub p/ approx. = 800 kA, a = 68 cm, R = 250 cm, and B/sub t/ = 27 kG. A maximum plasma current of 1 MA was achieved with q approx. = 2.5. Energy confinement times of approx. 150 msec were measured for hydrogen and deuterium plasmas with anti n/sub e/ approx. = 2 x 1013 cm-3, T/sub e/ (0) approx. = 1.5 keV, T/sub i/ (0) approx. = 1.5 keV, and Z/sub eff/ approx. = 3. The preliminary results suggest a size-cubed scaling from PLT and are consistent with Alcator C scaling where tau approx. nR2a. Initial measurements of plasma disruption characteristics indicate current decay rates of approx. 800 kA in 8 ms which is within the TFTR design requirement of 3 MA in 3 ms

  13. Optimizing parallel reduction operations

    Energy Technology Data Exchange (ETDEWEB)

    Denton, S.M.

    1995-06-01

    A parallel program consists of sets of concurrent and sequential tasks. Often, a reduction (such as array sum) sequentially combines values produced by a parallel computation. Because reductions occur so frequently in otherwise parallel programs, they are good candidates for optimization. Since reductions may introduce dependencies, most languages separate computation and reduction. The Sisal functional language is unique in that reduction is a natural consequence of loop expressions; the parallelism is implicit in the language. Unfortunately, the original language supports only seven reduction operations. To generalize these expressions, the Sisal 90 definition adds user-defined reductions at the language level. Applicable optimizations depend upon the mathematical properties of the reduction. Compilation and execution speed, synchronization overhead, memory use and maximum size influence the final implementation. This paper (1) Defines reduction syntax and compares with traditional concurrent methods; (2) Defines classes of reduction operations; (3) Develops analysis of classes for optimized concurrency; (4) Incorporates reductions into Sisal 1.2 and Sisal 90; (5) Evaluates performance and size of the implementations.

  14. Advanced Neutron Source operating philosophy

    International Nuclear Information System (INIS)

    An operating philosophy and operations cost estimate were prepared to support the Conceptual Design Report for the Advanced Neutron Source (ANS), a new research reactor planned for the Oak Ridge National Laboratory (ORNL). The operating philosophy was part of the initial effort of the ANS Human Factors Program, was integrated into the conceptual design, and addressed operational issues such as remote vs local operation; control room layout and responsibility issues; role of the operator; simulation and training; staffing levels; and plant computer systems. This paper will report on the overall plans and purpose for the operations work, the results of the work done for conceptual design, and plans for future effort

    Field operators are widely used in many-body theory of indistinguishable particles. In this work it is shown that these operators can be represented solely in position space. Explicit expressions for the field operators in position space are given. Using the derived expression, we further show how by generalizing operators in first quantization to arbitrary particle numbers, one can directly connect to the respective operators in second quantization. A few illustrative examples are also presented. PMID:26594868

    Operating systems research has traditionally consisted of adding functionality to the operating system or inventing and evaluating new methods for performing functions. Regardless of the research goal, the single constant has been that the size and complexity of operating systems increase over time. As a result, operating systems are usually the single most complex piece of software in a computer system, containing hundreds of thousands, if not millions, of lines of code. Today’s operating sy...

    Hausdorff operator is an important operator raised from the dilation on Euclidean space and rooted in the classical summability of number series and Fourier series. It is also connected to many well known operators in real and complex analysis. This article is a survey of some recent developments and extensions on the Hausdorff operator. Particularly, various boundedness properties of the Hausdorff operators, studied recently by our research group, are addressed.

  18. The positive radial momentum operator

    2003-01-01

    The Laplacian in spherical coordinates contains the squared radial momentum operator $ p_r^2 = - r^{-1} \\partial_r^2 r $ which is Hermitian and positive. However as has been pointed out by various authors the ``radial momentum operator" $ - i r^{-1} \\partial_r r $ is not Hermitian. The positive square root operator of $ p_r^2 $ is found and also its inverse. We discuss the relation of these operators with Fourier transforms, the Hilbert transform and fractional integral operators.

    The Relativistic Heavy Ion Collider (RHIC) operation as the polarized proton collider presents unique challenges since both luminosity(L) and spin polarization(P) are important. With longitudinally polarized beams at the experiments, the figure of merit is LP{sup 4}. A lot of upgrades and modifications have been made since last polarized proton operation. A 9 MHz rf system is installed to improve longitudinal match at injection and to increase luminosity. The beam dump was upgraded to increase bunch intensity. A vertical survey of RHIC was performed before the run to get better magnet alignment. The orbit control is also improved this year. Additional efforts are put in to improve source polarization and AGS polarization transfer efficiency. To preserve polarization on the ramp, a new working point is chosen such that the vertical tune is near a third order resonance. The overview of the changes and the operation results are presented in this paper. Siberian snakes are essential tools to preserve polarization when accelerating polarized beams to higher energy. At the same time, the higher order resonances still can cause polarization loss. As seen in RHIC, the betatron tune has to be carefully set and maintained on the ramp and during the store to avoid polarization loss. In addition, the orbit control is also critical to preserve polarization. The higher polarization during this run comes from several improvements over last run. First we have a much better orbit on the ramp. The orbit feedback brings down the vertical rms orbit error to 0.1mm, much better than the 0.5mm last run. With correct BPM offset and vertical realignment, this rms orbit error is indeed small. Second, the jump quads in the AGS improved input polarization for RHIC. Third, the vertical tune was pushed further away from 7/10 snake resonance. The tune feedback maintained the tune at the desired value through the ramp.

  1. Reviewing operational experience feedback

    International Nuclear Information System (INIS)

    The purpose of this document is to provide detailed supplementary guidance to OSART experts to aid in the evaluation of operational experience feedback (OEF) programmes at nuclear power plants. The document begins by describing the objectives of an OEF programme. It goes on to indicate preparatory work and investigatory guidance for the expert. Section 5 describes attributes of an excellent OEF programme. Appended to these guidelines are examples of OEF documents from various plants. These are intended to help the expert by demonstrating the actual implementation of OEF in practice. These guidelines are in no way intended to conflict with existing national regulations and rules. A comprehensive OEF programme, as described in Section 2, would be impossible to evaluated in detail in the amount of time typically allocated for assessing OEF in an OSART review. The expert must use his or her time wisely by concentrating on those areas that appear to be the weakest

    The requirements of the contract under which this work was performed were simple. It was required that we should bring back sleep and other physiological data from divers in the working environment. This we have done. The two divers studied do not give us sufficient evidence upon which to base conclusive statements, though the rapidity with which a normal sleep pattern was established in both divers suggests to us that operational demand rather than any hyperbaric influence on sleep physiology is the major factor causing fatigue offshore. The temperature work reported is an additional study, not originally contained in the contract. The work was performed in response to a need for information from Oceaneering/Vickers Oceanics and we thank them for the opportunity. This work shows that divers using their system do undoubtably get cold, but that the recently introduced space undersuit provides considerable protection. (UK)

  3. Operator product expansion algebra

    International Nuclear Information System (INIS)

    The Operator Product Expansion (OPE) is a theoretical tool for studying the short distance behaviour of products of local quantum fields. Over the past 40 years, the OPE has not only found widespread computational application in high-energy physics, but, on a more conceptual level, it also encodes fundamental information on algebraic structures underlying quantum field theories. I review new insights into the status and properties of the OPE within Euclidean perturbation theory, addressing in particular the topics of convergence and ''factorisation'' of the expansion. Further, I present a formula for the ''deformation'' of the OPE algebra caused by a quartic interaction. This formula can be used to set up a novel iterative scheme for the perturbative computation of OPE coefficients, based solely on the zeroth order coefficients (and renormalisation conditions) as initial input.

    A counter operating system creates a hierarchy of levels of abstraction, so that at a given level all details concerning lower levels can be ignored. This hierarchical structure separates functions according to their complexity, characteristic time scale, and level of abstraction. The lowest levels include the system's hardware; concepts associated explicitly with the coordination of multiple tasks appear at intermediate levels, which conduct 'primitive processes'. Software semaphore is the mechanism controlling primitive processes that must be synchronized. At higher levels lie, in rising order, the access to the secondary storage devices of a particular machine, a 'virtual memory' scheme for managing the main and secondary memories, communication between processes by way of a mechanism called a 'pipe', access to external input and output devices, and a hierarchy of directories cataloguing the hardware and software objects to which access must be controlled.

    's safety standards and program which provides the safety objective following the 10 fundamental safety principles. The safety requirements defines the functional conditions required for safety and the safety guides provides user-friendly and up-to-date practical guidance representing good/best practices to fulfill the requirements. The IAEA provides safety review services and fields safety review teams upon request of member states for the regulatory, the International Regulatory Review Team (IRRT) and Operational Safety Review Team (OSART) and Peer Review of the Operational and Safety Performance Experience Review (PROSPER). The OSART programme's purpose is to assist member states in enhancing the operational safety of individual nuclear power plants and to promote the continuous development of operational safety within all member states by the dissemination of information on good practice. The OSART Mission Results (OSMIR) database contains the results from 73 OSART missions and 54 follow up visits from 1991 and its continually updated. The Asian Nuclear Safety Network (ANSN) was established to pool and share existing and new technical knowledge and practical experience to further improve the safety of nuclear installation in Asia. In summary, the enhancement of the GNSR is anchored in the recognition that all the states are in the same boat and the increasing importance of sharing and mutual learning, sharing knowledge and experience through regional and global networking. It requires joint and coordinated strategy by all states. The IAEA is willing and ready to support the GNSR through the establishment and application of safety standards, and safety review and advisory services and international instruments. (Author)

    International Nuclear Information System (INIS)

    Since the TRIGA Users Conference in Helsinki 1970 the TRIGA reactor Vienna was in operation without any larger undesired shutdown. The integrated thermal power production by August 15 1972 accumulated to 110 MWd. The TRIGA reactor is manly used for training of students, for scientific courses and research work. Cooperation with industry increased in the last two years either in form of research or in performing training courses. Close cooperation is also maintained with the IAEA, samples are irradiated and courses on various fields are arranged. Maintenance work was performed on the heat exchanger and to replace the shim rod magnet. With the view on the future power upgrading nine fuel elements type 110 have been ordered recently. Experiments, performed currently on the reactor are presented in details

    Sour crudes currently account for 33 per cent of natural gas production in Canada. It is expected that they will account for 40 per cent of production within 10 years and production will be nearer to populated areas. This presentation discussed public safety issues associated with sour gas production and the impact that the Kyoto Protocol may have on emissions reductions, energy efficiency and sulfur recovery. Key issues for Canadian oil and natural gas include competitiveness, access to resources, open access to markets, and environmental/safety performance. The management of sour gas operations in terms of flaring/venting and plume dispersion was discussed along with regulatory updates, emergency response planning, and stakeholder consultations. The impact that revisions to Guide 60 will have have on flaring and venting practices in Alberta was also addressed. The expectations for future demand markets were highlighted with reference to the potential to generate electricity with sour gas. 8 figs.

    Although the area of International Manufacturing Network (IMN) and International Operations Network (ION) has received considerable attention in the literature, most of studies appear multifaceted and interdisciplinary, and thereby require thorough investigation from both academic and practical perspectives, in order to deepen our related understanding. The book seeks advanced contributions that will combine theoretical insights and empirical experience by offering a detailed examination of IMN and, further, ION from various perspectives. This book can be used as a reference material for scholarpractitioners, business executives, and university researchers who need to deepen their understanding on the importance and influence of IMN and ION as well as their development. The book is important because there are few reference/resource materials available related to IMN and ION.

    Full Text Available Mathematical modelling, analysis and computing of problems with uncertainty is one of the hottest areas in interdisciplinary research involving applied mathematics, computational intelligence and decision sciences. It is worth noting that uncertainty arises from various domains has very different nature and cannot be captured within a single mathematical framework. Molodtsov’s soft sets provide us a new way of coping with uncertainty from the viewpoint of parameterization. In this paper, we introduce the concepts of soft graphs, vertex-induced soft graphs, edge-induced soft graphs and describe some operations on soft graphs by presenting several examples to demonstrate these new concepts. Finally, we investigate some fundamental properties of soft graphs.

    This paper reports that reports of damage caused by Hurricane Andrew were leveling off last week at the U.S. Minerals Management Service as Gulf of Mexico operators pressed ahead with repairs. The hurricane struck South Florida Aug. 4, churned west into the gulf, then swung north and hit the South Louisiana coast Aug. 5. By the close of business Sept. 8 MMS had received damage reports covering 83 pipeline segments and 193 platforms and satellite installations. MMS last week estimated about 500 MMcfd of gas production had been restored in the gulf and 100,000-150,000 b/d of oil. Production still lost as a result of Andrew was estimated at 2-2.5 bcfd of gas and 90,000-120 b/d of oil. MMS estimates Gulf of Mexico wells before the storm were producing about 12.5-13 bcfd of gas and 750,000 b/d of oil

    2015-01-01

    The focus of this talk is on the transverse components of parton momenta. Like for collinear parton distribution functions (PDFs), we are also in the case of transverse momentum dependent (TMD) PDFs, talking about forward matrix elements. While the collinear PDFs describe only spin-spin correlations, the TMD PDFs (or in short TMDs) include spin-momentum correlations, including also time-reversal-odd (T-odd) correlations. The latter are important in the description of single spin asymmetries. In this way TMDs open up new ways of studying the spin structure of hadrons or they can be used as tools that incorporate hadronic structure also in non-collinear situations. The operator structure of TMDs within QCD, in particular the structure of Wilson lines, is more complex than that for collinear functions leading to various ways of breaking of universality. This breaking of universality, however, can be handled within QCD.

  16. KEPLER SCIENCE OPERATIONS

    International Nuclear Information System (INIS)

    Kepler's mission design includes a comprehensive plan for commissioning and science operations. The commissioning phase completed all critical tasks and accomplished all mission objectives within a week of the pre-launch plan. Since the start of science data collection, the nominal timeline has been interrupted by two safe-mode events, several losses of fine point, and some small pointing adjustments. The most important anomalies are understood and mitigated, so Kepler's technical performance has improved significantly over this period, and the prognosis for mission success is excellent. The Kepler data archive is established and hosting data for the science team, guest observers, and the public. The first data to become publicly available include the monthly full-frame images and the light curves for targets that are dropped from the exoplanet program or released after publication. Data are placed in the archive on a quarterly basis; the Kepler Results Catalog will be released annually starting in 2011.

    This paper reports that Gulf of Mexico operators last week were gradually restoring production at installations struck by Hurricane Andrew. The Minerals Management Service continued receiving reports of more damage. By the end of the day Sept. 8, MMS had received reports of damage to 83 pipeline segments and 193 platforms and satellite installations. Damage reports listed 112 installations with structural damage, 13 platforms toppled and five leaning, and 30 satellite platforms toppled and 33 leaning. But despite the extent of damage the storm inflicted on oil and gas installations in the gulf, it pales in comparison to the misery and suffering the storm caused in Florida and Louisiana, an oil company official said

  19. Modern operative hysteroscopy.

    2016-04-01

    Hysteroscopy is an endoscopic surgical procedure that has become an important tool to evaluate intrauterine pathology. It offers a direct visualization of the entire uterine cavity and provides the possibility of performing biopsy of suspected lesions that can be missed by dilatation and curettage (D&C). In most cases, the intrauterine pathologies can be diagnosed and treated at the same setting as office hysteroscopy ("see and treat approach"). For example, endometrial polyps can be diagnosed and removed; similarly, intrauterine adhesions can be liberated in the outpatient setting without the need for an operating theatre. Today, many hysteroscopic procedures can be performed in the office or outpatient setting. This is due to the feasibility of operative hysteroscopy using saline as a distending medium, the vaginoscopic approach of hysteroscopy and the availability of mini-hysteroscopic endoscopes. There is good evidence to suggest that hysteroscopy in an ambulatory setting is preferable for the patient, and that it avoids complications, allows a quicker recovery time and lowers cost. Advances in technology have led to miniaturization of high-definition hysteroscopes without compromising optical performance, thereby making hysteroscopy a simple, safe and well-tolerated office procedure. The new surgical technology such as bipolar electrosurgery, endometrial ablation devices, hysteroscopic sterilization, and morcellators has revolutionized this surgical modality. The modern development of hysteroscopy completely transformed the approach to the uterine intracavitary pathologies moving from a blind procedure under general anesthesia to an outpatient procedure performed under direct visualization, offering therapeutic and irreplaceable possibilities of treatment that should belong to every modern gynecologist.

  20. Regulatory and operating experience

    International Nuclear Information System (INIS)

    Regulatory and operating experience in the disposal of radioactive waste can be divided into three time periods, World War II and its aftermath, Post World War II till the end of the cold war, and crystal ball gazing into the future. In the first period, there was little regulatory guidance and operating practices, all conducted under wartime secrecy conditions, sometimes were not even up to the norms of the times. Environmental releases resulted in some seriously contaminated sites and high dosages to some offsite populations. Failure to consider even the storage of wastes in a systems context resulted in some stocks that were difficult to recover, treat and dispose of in a final manner. In the second period, increasing civilian uses of nuclear power and isotopes for medical, research, and industrial purposes and military pressure for increased production of Pu-239 resulted in large and more dispersed disposal of radioactive wastes. Regulatory regimes, following growing environmental consciousness, came into existence that minimized exposure to environmental contamination. Practices, in most instances, increasingly conformed to these regulatory demands. The future is unknowable. However, for high level wastes, except for thermodynamically stable forms, no technology can guarantee safety and present methodologies are calculated to produce doses orders of magnitude lower than regulatory limits. Therefore, it is possible that research will be limited to no higher technology than is reasonably achievable. Whereas for low level waste, where proof is practicably possible, as high technology as is reasonably achievable will be best in the long run. (author). 24 refs, 5 figs, 3 tabs

    At the beginning of electricity generation from nuclear power there was the breeder, which fulfilled its duty in a number of smaller test and experimental reactors within national programs. Over the years, some of those reactors have attained impressive availabilities, while others have helped to improve our knowledge by the negative results they contributed. Worldwide a decisive step was taken by the mid- to late sixties in the planning and construction of medium sized demonstration fast breeder power plants (250 to 350 MW). In the Federal Republik of Germany, this step is taken belatedly in building the SNR-300. BN-350 in the USSR, Phenix in France, and PFR in the United Kingdom have now been in operation for some ten years. Over that period, valuable experience has been accumulated in sodium technology. The operating behavior of all components and systems working in sodium is called excellent; the hazards associated with sodium, the fire hazard in particular, thus often seem to be greatly overrated. Leakages have been brought under control. It has always been possible so far to trace them back to systemic faults produced in the welding process. The ability of fast sodium cooled reactors to produce more nuclear fuel than they consume has been demonstrated in Phenix, whose breeding ration has been measured to be 1.16. The first true large breeder, Super Phenix in France, is to be commissioned already in 1985. In building another three breeder power plants the European partners in an association hope to achieve the commercial breakthrough of the breeder line. (orig.)

  2. Motor-operator gearbox efficiency

    International Nuclear Information System (INIS)

    Researchers at the Idaho National Engineering Laboratory recently conducted tests investigating the operating efficiency of the power train (gearbox) in motor-operators typically used in nuclear power plants to power motor-operated valves. Actual efficiency ratios were determined from in-line measurements of electric motor torque (input to the operator gearbox) and valve stem torque (output from the gearbox) while the operators were subjected to gradually increasing loads until the electric motor stalled. The testing included parametric studies under reduced voltage and elevated temperature conditions. As part of the analysis of the results, we compared efficiency values determined from testing to the values published by the operator manufacturer and typically used by the industry in calculations for estimating motor-operator capabilities. The operators we tested under load ran at efficiencies lower than the running efficiency (typically 50%) published by the operator manufacturer

  5. Operations on soft sets revisited

    Zhu, Ping

    2012-01-01

    Soft sets, as a mathematical tool for dealing with uncertainty, have recently gained considerable attention, including some successful applications in information processing, decision, demand analysis, and forecasting. To construct new soft sets from given soft sets, some operations on soft sets have been proposed. Unfortunately, such operations cannot keep all classical set-theoretic laws true for soft sets. In this paper, we redefine the intersection, complement, and difference of soft sets and investigate the algebraic properties of these operations along with a known union operation. We find that the new operation system on soft sets inherits all basic properties of operations on classical sets, which justifies our definitions.

  7. PDX divertor operation

    International Nuclear Information System (INIS)

    PDX was brought into operation in January 1980 as a diverted tokamak with typical parameters of Bsub(T) = 15-20 kG, a = 38 cm, R0 = 123-159 cm, Isub(p) = 180-300 kA, q approx. equal to 3.7, anti nsub(e) = 1-3.8 x 1013 cm-3, anti Z = 1.1-3, tausub(E)sub(e) approx. equal to 25 ms, and pulse lengths up to 0.7 s. Internal vacuum components that were exposed to the plasma (such as limiters, shields, microwave horns, etc.) were fabricated from 99% pure titanium. Glow discharge cleaning with 3 x 10-2 Torr H2 and pulse discharge cleaning were used to condition the vessel for high power discharges. For the divertor studies, work has concentrated on obtaining long, high current stable discharges. Radial position, plasma current, and gas injection control systems have been used to facilitate this effort. Discharges of inside-D, square, and inverse-D cross-section have been produced. Microwave interferometers, spectroscopy, an X-ray pulse height analyzer system, scanning and fixed bolometers, and thermocouple array have been used to determine plasma and impurity densities, temperature, radiation, and power loss to the divertor. A comparison of diverted and undiverted discharges is presented. (orig.)

    Over the last few years, numerical prediction of dust aerosol concentration has become prominent at several research and operational weather centres due to growing interest from diverse stakeholders, such as solar energy plant managers, health professionals, aviation and military authorities and policymakers. Dust prediction in numerical weather prediction-type models faces a number of challenges owing to the complexity of the system. At the centre of the problem is the vast range of scales required to fully account for all of the physical processes related to dust. Another limiting factor is the paucity of suitable dust observations available for model, evaluation and assimilation. This chapter discusses in detail numerical prediction of dust with examples from systems that are currently providing dust forecasts in near real-time or are part of international efforts to establish daily provision of dust forecasts based on multi-model ensembles. The various models are introduced and described along with an overview on the importance of dust prediction activities and a historical perspective. Assimilation and evaluation aspects in dust prediction are also discussed.

    2001-01-01

    Accurate data is important in the aviation planning process. In this project we consider systems for measuring aircraft activity at airports. This would include determining the type of aircraft such as jet, helicopter, single engine, and multiengine propeller. Some of the issues involved in deploying technologies for monitoring aircraft operations are cost, reliability, and accuracy. In addition, the system must be field portable and acceptable at airports. A comparison of technologies was conducted and it was decided that an aircraft monitoring system should be based upon acoustic technology. A multimedia relational database was established for the study. The information contained in the database consists of airport information, runway information, acoustic records, photographic records, a description of the event (takeoff, landing), aircraft type, and environmental information. We extracted features from the time signal and the frequency content of the signal. A multi-layer feed-forward neural network was chosen as the classifier. Training and testing results were obtained. We were able to obtain classification results of over 90 percent for training and testing for takeoff events.

  11. Operator bosonization on Riemann surfaces: new vertex operators

    International Nuclear Information System (INIS)

    A new formalism is presented for building an operator theory of generalized ghost systems (bc theories of spin J) on Riemann surfaces (loop diagrams of the closed string theory). Operators of the bc system are expressed through the operators of a bosonic conformal theory on a Riemann surface. As distinct from standard bosonization formulas, which have meaning only locally, the Baker-Akhiezer operator functions are introduced which are globally well defined on a Riemann surface of arbitrary form. The operator algebra of Baker-Akhiezer functions generates explicity the algebraic-geometrical τ function and correlation functions of bc systems on Riemann surfaces

    2008-10-01

    The implementation of 3 dimensions spatial operations, based on certain data structure, has a lack of universality and is not able to treat with non-manifold cases, at present. ISO/DIS 19107 standard just presents the definition of Boolean operators and set operators for topological relationship query, and OGC GeoXACML gives formal definitions for several set functions without implementation detail. Aiming at these problems, based mathematical foundation on cell complex theory, supported by non-manifold data structure and using relevant research in the field of non-manifold geometry modeling for reference, firstly, this paper according to non-manifold Euler-Poincaré formula constructs 6 extended Euler operators and inverse operators to carry out creating, updating and deleting 3D spatial elements, as well as several pairs of supplementary Euler operators to convenient for implementing advanced functions. Secondly, we change topological element operation sequence of Boolean operation and set operation as well as set functions defined in GeoXACML into combination of extended Euler operators, which separates the upper functions and lower data structure. Lastly, we develop underground 3D GIS prototype system, in which practicability and credibility of extended Euler operators faced to 3D GIS presented by this paper are validated.

  5. Synergy, a co-operative innovation for joint operations

    International Nuclear Information System (INIS)

    Industry cooperation in the operation of the large Swan Hills oil field in western Alberta is described. Declining production and increasing costs required innovative approaches to field operation. Traditional operation involved one operator making the majority of decisions with funding controlled by numerous non-operating joint owners, and can suffer from interaction problems due to the inherenty competitive nature of the petroleum industry. The new mode of operation stresses trust, cooperation, teamwork, resource sharing, and continuous improvement. The synergy involves sharing best practices, information, knowledge and expertise, combining resources, and standardizing procedures and specifications. The new mode of operation has resulted in an improved performance of up to 15%. The cooperation lessons learnt at Swan Hills may have broad application across the petroleum industry. 6 refs., 6 figs

    Chefles, Anthony; Kitagawa, Akira; Takeoka, Masahiro; Sasaki, Masahide; Twamley, Jason

    2007-08-01

    We address the problem of unambiguous discrimination among oracle operators. The general theory of unambiguous discrimination among unitary operators is extended with this application in mind. We prove that entanglement with an ancilla cannot assist any discrimination strategy for commuting unitary operators. We also obtain a simple, practical test for the unambiguous distinguishability of an arbitrary set of unitary operators on a given system. Using this result, we prove that the unambiguous distinguishability criterion is the same for both standard and minimal oracle operators. We then show that, except in certain trivial cases, unambiguous discrimination among all standard oracle operators corresponding to integer functions with fixed domain and range is impossible. However, we find that it is possible to unambiguously discriminate among the Grover oracle operators corresponding to an arbitrarily large unsorted database. The unambiguous distinguishability of standard oracle operators corresponding to totally indistinguishable functions, which possess a strong form of classical indistinguishability, is analysed. We prove that these operators are not unambiguously distinguishable for any finite set of totally indistinguishable functions on a Boolean domain and with arbitrary fixed range. Sets of such functions on a larger domain can have unambiguously distinguishable standard oracle operators, and we provide a complete analysis of the simplest case, that of four functions. We also examine the possibility of unambiguous oracle operator discrimination with multiple parallel calls and investigate an intriguing unitary superoperator transformation between standard and entanglement-assisted minimal oracle operators.

  12. Factorizing the time evolution operator

    International Nuclear Information System (INIS)

    There is a widespread belief in the quantum physical community, and textbooks used to teach quantum mechanics, that it is a difficult task to apply the time evolution operator eitH-hat/h on an initial wavefunction. Because the Hamiltonian operator is, generally, the sum of two operators, then it is not possible to apply the time evolution operator on an initial wavefunction ψ(x, 0), for it implies using terms like (a-hat + b-hat). A possible solution is to factorize the time evolution operator and then apply successively the individual exponential operator on the initial wavefunction. However, the exponential operator does not directly factorize, i.e. ea-hat+b-hat ≠ ea-hat eb-hat. In this study we present a useful procedure for factorizing the time evolution operator when the argument of the exponential is a sum of two operators, which obey specific commutation relations. Then, we apply the exponential operator as an evolution operator for the case of elementary unidimensional potentials, like a particle subject to a constant force and a harmonic oscillator. Also, we discuss an apparent paradox concerning the time evolution operator and non-spreading wave packets addressed previously in the literature

  14. NPD Operating Experience

    International Nuclear Information System (INIS)

    NPD has demonstrated high-capacity factor operation and for the past three years has achieved an average net capacity factor of 98% for the ''winter-peak'' period. The net capacity factor for the year 1966 was 88% and for the period from the end of commissioning (October 1962) to the end of 1966 was 71%. The output of the station has been stretched from 22 MW(e) gross to 25 MW(e) gross. This was aided by the installation of an internal steam separator in the turbine but no basic modifications to the reactor-boiler systems were required. The turbine has also been modified by the installation of chrome steel diaphragms as a solution to an erosion problem. The station also continues as a test facility to develop new components and techniques. This includes the recent successful replacement of two reactor pressure tubes and the conversion of the reactor vault ventilation system to a ''dry'' atmosphere using a molecular sieve to collect heavy-water leakage and control the concentration of acidic oxides of nitrogen. Fuel performance has been excellent and the average burn-up in the core is now 84 MWh/kg U which is slightly above the equilibrium design value. Only three fuel bundles have been found with sheath failures and none of these was due to a deficiency in the fuel but was as a result of handling problems with the refuelling equipment. In spite of undesirably high maintenance time, the fuelling machines have now inserted over 1000 fuel bundles into the reactor ''on power''. Heavy-water loss rates have been acceptable and are improving. The average loss rate from leaks during 1966 was 210 g/h. A proposal to modify the NPD heavy-water heat transport system to allow boiling is under consideration. (author)

  15. LSST operation simulator implementation

    2006-06-01

    We have developed an operation simulator for the Large Synoptic Survey Telescope (LSST) that is an implementation in Python language using the SimPy extension, with a modular and object-oriented design. The main components include a telescope model, a sky model, a weather database for 3 sites, a scheduler and multiple observing proposals. All the proposals derive from a parent class which is fully configurable through about 75 parameters to implement a specific science survey. These parameters control the target selection region, the composition of the sequence of observations for each field, the timing restrictions and filter selection criteria of each observation, the lunation handling, seeing limits, etc. The current implemented proposals include Weak Lensing, Near Earth Asteroids, Supernova and Kuiper Belt Objects. The telescope model computes the slew time delay from the current position to any given target position, using a complete kinematic model for the mount, dome and rotator, as well as optics alignment corrections. The model is fully configurable through about 50 parameters. The scheduler module combines the information received from the proposals and the telescope model for selecting the best target at each moment, promoting targets that fulfill multiple surveys and storing all the simulator activities in a MySQL database for further analysis of the run. This scheduler is also configurable; for example, balancing the weight of the slew time delay in selecting the next field to observe. This simulator has been very useful in clarifying some of the technical and scientific capabilities of the LSST design, and gives a good baseline for a future observation scheduler.

    The operating theatre complex is the heart of any major surgical hospital. Good operating theatre design meets the functional needs of theatre care professionals. Operating theatre design must pay careful consideration to traffic patterns, the number and configuration of nearby operating rooms, the space required for staff, administration and storage, provisions for sterile processing and systems to control airborne contaminants (Wan et al 2011). There have been infection control issues with private finance initiative built operating theatres (Unison 2003, Ontario Health Coalition 2005). The aim of this article is to address these issues as they relate to infection control and prevention. PMID:23162994

    International Nuclear Information System (INIS)

    Conflicts over control of shared devices or resources in an accelerator control system, and problems that can occur due to applications performing conflicting operations, are usually resolved by accelerator operators. For these conflicts to be detected by the control system, a model of accelerator operation must be available to the system. The authors present a design for an operation management system addressing the issues of operations management using the language of Object-Oriented Design (OOD). A possible implementation using commercially available software tools is also presented

    The problems concerning the invariant operators of the W(p, q) Weyl group of arbitrary dimension are considered. The Weyl group relative invariants, which do not contain the dilatation operators and which are the absolute invariants of the ISO (p, q) group, are searched for. The invariant operators of the Weyl group are represented in the form of the ratio of the Cazimir operators of the inhomogeneous pseudoorthogonal subgroup. It is shown that all the invariant operators of the W(p, q) Weyl group are rational and their number is [p+q-1/2

  1. Modeling aerial refueling operations

    Science.gov (United States)

    McCoy, Allen B., III

    Aerial Refueling (AR) is the act of offloading fuel from one aircraft (the tanker) to another aircraft (the receiver) in mid flight. Meetings between tanker and receiver aircraft are referred to as AR events and are scheduled to: escort one or more receivers across a large body of water; refuel one or more receivers; or train receiver pilots, tanker pilots, and boom operators. In order to efficiently execute the Aerial Refueling Mission, the Air Mobility Command (AMC) of the United States Air Force (USAF) depends on computer models to help it make tanker basing decisions, plan tanker sorties, schedule aircraft, develop new organizational doctrines, and influence policy. We have worked on three projects that have helped AMC improve its modeling and decision making capabilities. Optimal Flight Planning. Currently Air Mobility simulation and optimization software packages depend on algorithms which iterate over three dimensional fuel flow tables to compute aircraft fuel consumption under changing flight conditions. When a high degree of fidelity is required, these algorithms use a large amount of memory and CPU time. We have modeled the rate of aircraft fuel consumption with respect to AC GrossWeight, Altitude and Airspeed. When implemented, this formula will decrease the amount of memory and CPU time needed to compute sortie fuel costs and cargo capacity values. We have also shown how this formula can be used in optimal control problems to find minimum costs flight plans. Tanker Basing Demand Mismatch Index. Since 1992, AMC has relied on a Tanker Basing/AR Demand Mismatch Index which aggregates tanker capacity and AR demand data into six regions. This index was criticized because there were large gradients along regional boundaries. Meanwhile tankers frequently cross regional boundaries to satisfy the demand for AR support. In response we developed continuous functions to score locations with respect to their proximity to demand for AR support as well as their

    At Thomas Jefferson National Accelerator Facility, accelerator operators perform tasks in their areas of specialization in addition to their machine operations duties. One crucial area in which operators contribute is software development. Operators with programming skills are uniquely qualified to develop certain controls applications because of their expertise in the day-to-day operation of the accelerator. Jefferson Lab is one of the few laboratories that utilizes the skills and knowledge of operators to create software that enhances machine operations. Through the programs written; by operators, Jefferson Lab has improved machine efficiency and beam availability. Because many of these applications involve automation of procedures and need graphical user interfaces, the scripting language Tcl and the Tk toolkit have been adopted. In addition to automation, some operator-developed applications are used for information distribution. For this purpose, several standard web development tools such as perl, VBScript, and ASP are used. Examples of applications written by operators include injector steering, spin angle changes, system status reports, magnet cycling routines, and quantum efficiency measurements. This paper summarizes how the unique knowledge of accelerator operators has contributed to the success of the Jefferson Lab control system. *This work was supported by the U.S. DOE contract No. DE-AC05-84-ER40150

  3. Factorizing the time evolution operator

    Quijas, P C G

    2006-01-01

    There is a widespread belief in the quantum physical community, and in textbooks used to teach Quantum Mechanics, that it is a difficult task to apply the time evolution operator on an initial wave function. That is to say, because the hamiltonian operator generally is the sum of two operators, then it is a difficult task to apply the time evolution operator on an initial wave function, because it implies to apply terms like (A+B)^n. A possible solution of this problem is to factorize the time evolution operator and then apply successively the individual exponential operator on the initial wave function. However, the exponential operator does not directly factorize. In this work we present useful ways to factorizing the time evolution operator when the argument of the exponential is a sum of two operators which obey specific commutation relations. Then, we apply the exponential operator as an evolution operator for the case of elementary unidimensional potentials, like the harmonic oscillator. Also, we argue ...

    In this article, we give an operator transform (∧T)(*) from class A operator to the class of hyponormal operators. It is different from the operator transform (∧T) defined by M.Chō and T. Yamazaki. Then, we show that σ(T) = σ(∧T)(*)) and σa(T)\\{0} = σa(∧T)(*))\\{0},in case T belongs to class A. Next, we obtain some relations between (∧T) and (∧T)(*).

  5. Operator companion for CANDU reactors

    International Nuclear Information System (INIS)

    As CANDU nuclear power plants become more complex, and are operated under tighter constraints and for longer periods between outages, plant operations staff will have to absorb more information to correctly and rapidly respond to upsets. A development program is underway at Atomic Energy of Canada Limited to use expert systems and interactive media tools to assist operations staff of existing and future CANDU plants. The complete system for plant information access and display, on-line advice and diagnosis, and interactive operating procedures is called the Operator Companion. A prototype, consisting of operator consoles, expert systems and simulation modules in a distributed architecture, is currently being developed to demonstrate the concepts of the Operator Companion.

    Johnston, Gary M.; Campbell, Roy H.

    1988-01-01

    This paper describes a multiprocessor operating system simulator that was developed by the authors in the Fall semester of 1987. The simulator was built in response to the need to provide students with an environment in which to build and test operating system concepts as part of the coursework of a third-year undergraduate operating systems course. Written in C++, the simulator uses the co-routine style task package that is distributed with the AT&T C++ Translator to provide a hierarchy of classes that represents a broad range of operating system software and hardware components. The class hierarchy closely follows that of the 'Choices' family of operating systems for loosely- and tightly-coupled multiprocessors. During an operating system course, these classes are refined and specialized by students in homework assignments to facilitate experimentation with different aspects of operating system design and policy decisions. The current implementation runs on the IBM RT PC under 4.3bsd UNIX.

  7. Claims of operators, non-operators and third parties arising from oil and gas operations

    International Nuclear Information System (INIS)

    There has come a resurgence in the number of companies involved in the oil and gas industry seeking protection from their creditors because of the recent weakness in commodity prices. Because most operations in this industry are conducted jointly, a single insolvency can lead to a toppling of other participants in the joint venture and beyond. The problem is to minimize one's losses if other members of the joint venture become insolvent. An examination is included of some remedies which may be available to operators, non-operators and third parties when faced with an insolvent oil and gas participant. The remedies which may be available to the non-operator that is owed moneys by its operator are discussed. The remedies that the operator has against its non-operators, with an emphasis on the nature of the operator's lien and the right of set-off, are described. A brief review is included of some of the remedies that might be available to a third party as against the operators and non-operators. Some s uggestions are included for directors, bankers, third parties, non-operators and operators

  9. Optimum operation cycle of nuclear plant in power system operation

    International Nuclear Information System (INIS)

    Extension of nuclear power plant operation cycle leads to improvement of its capacity factor and affects to suppress thermal plant generation of which fuel cost is relatively high. On the other hand, the number of nuclear fuel assembly to be exchanged at the time of maintenance increases with the operation cycle extension and this makes the fuel cost of nuclear generation high. For this reason, there exists the optimum operation cycle from the power system operation. This report deals with the optimum operation cycle of nuclear plant as the optimum sharing problem of generated energy between nuclear and thermal plants. The incremental fuel cost is considered to find the optimum value. The effects of the generation mix and high burn-up fuel on optimum operation cycle are examined. (author)

    2015-01-01

    Medical supply during military operations has the ability to affect the efficacy of the operation being undertaken, either negatively or positively. An appropriately-managed maritime platform with a robust medical supply chain during transit and on arrival in theatre is the main aim. A secure supply chain will reduce any implications that logistics may have with regard to capability, and negate the effects of deficiencies of short shelf life items occurring over time and during use in high tempo operations.

    2015-12-01

    Full Text Available In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability and maintainability of equipment. There are a number of technologies to monitor, control, and maintain gas, oil, water, and sewer pipelines. The paper focuses on operational modal analysis (OMA application for condition monitoring of operating pipelines. Special focus is on the topicality of OMA for definition of the dynamic features of the pipeline (frequencies and mode shapes in operation. The research was conducted using two operating laboratory models imitated a part of the operating pipeline. The results of finite-element modeling, identification of pipe natural modes and its modification under the influence of virtual failure are discussed. The work considers the results of experimental research of dynamic behavior of the operating pipe models using one of OMA techniques and comparing dynamic properties with the modeled data. The study results demonstrate sensitivity of modal shape parameters to modification of operating pipeline technical state. Two strategies of pipeline repair – with continuously condition-based monitoring with proposed technology and without such monitoring, was discussed. Markov chain reliability models for each strategy were analyzed and reliability improvement factor for proposed technology of monitoring in compare with traditional one was evaluated. It is resumed about ability of operating pipeline condition monitoring by measuring dynamic deformations of the operating pipe and OMA techniques application for dynamic properties extraction.

    This report highlights significant operating events involving observed or potential common-mode failures of solenoid-operated valves (SOVs) in US plants. These events resulted in degradation or malfunction of multiple trains of safety systems as well as of multiple safety systems. On the basis of the evaluation of these events, the Office for Analysis and Evaluation of Operational Data (AEOD) of the US Nuclear Regulatory Commission (NRC) concludes that the problems with solenoid-operated valves are an important issue that needs additional NRC and industry attention. This report also provides AEOD's recommendations for actions to reduce the occurrence of SOV common-mode failures. 115 refs., 7 figs., 2 tabs

  15. From EGEE Operations Portal towards EGI Operations Portal

    Science.gov (United States)

    Cordier, Hélène; L'Orphelin, Cyril; Reynaud, Sylvain; Lequeux, Olivier; Loikkanen, Sinikka; Veyre, Pierre

    Grid operators in EGEE have been using a dedicated dashboard as their central operational tool, stable and scalable for the last 5 years despite continuous upgrade from specifications by users, monitoring tools or data providers. In EGEE-III, recent regionalisation of operations led the Operations Portal developers to conceive a standalone instance of this tool. We will see how the dashboard reorganization paved the way for the re-engineering of the portal itself. The outcome is an easily deployable package customized with relevant information sources and specific decentralized operational requirements. This package is composed of a generic and scalable data access mechanism, Lavoisier; a renowned php framework for configuration flexibility, Symfony and a MySQL database. VO life cycle and operational information, EGEE broadcast and Downtime notifications are next for the major reorganization until all other key features of the Operations Portal are migrated to the framework. Features specifications will be sketched at the same time to adapt to EGI requirements and to upgrade. Future work on feature regionalisation, on new advanced features or strategy planning will be tracked in EGI- Inspire through the Operations Tools Advisory Group, OTAG, where all users, customers and third parties of the Operations Portal are represented from January 2010.

  16. Operation training for renovated JMTR

    International Nuclear Information System (INIS)

    JMTR once stopped its operation in August 2006. The subsequent refurbishment and the repair of the building block affected by the 2011 off the Pacific Coast of Tohoku Earthquake on March 11, 2011 have been completed, and it is preparing for the reoperation. As for the refurbishment of reactor facilities, taking into account the operation for further 20 years after the restart, and from the viewpoints of judging standards (aging deterioration of equipment, importance of safety function, and maintenance experience) for the safety ensuring against aging, the following facilities were replaced: (1) core of nuclear reactor body, (2) measurement and control system facilities, (3) reactor cooling system facilities, (4) emergency evacuation equipment of disposal facilities of gaseous waste, and (5) control facilities. In this remodeling, the operation methods for measurement and control system facilities (process instrumentation, nuclear instrumentation) have been changed. Therefore, regarding the reactor operation after the remodeling, examination was made on the methods to safely and reliably conduct important operations such as the criticality proximity of reactor and output increase, while monitoring the process instrumentation in the same way as before. Based on these examination results, the authors designed an operation manual, and have been performing operation training. This paper takes up the methods for reactor operation procedures that were changed by the refurbishment of the reactor, and summarizes the consideration points on the preparation of the operating manual, problems confirmed by practicing the operation training, and measures against those problems.

  17. Operating Experience at NPP Krsko

    International Nuclear Information System (INIS)

    Systematic analysis of operational experience by assessment of internal and industry events and the feedback of lessons learned is one of the essential activities in the improvement of the operational safety and reliability of the nuclear power plant. At NPP Krsko we have developed a document called ''Operating Experience Assessment Program''. Its purpose is to establish administrative guidance for the processing of operating events including on-site and industry events. Assessment of internal events is based on the following methods: Event and Causal Factor Charting, Change Analysis, Barrier Analysis, MORT (Management Oversight and Risk Tree Analysis) and Human Performance Evaluation. The operating experience group has developed a sophisticated program entitled ''Operating experience tracking system'' (OETS) in response to the need for a more efficient way of processing internal and industry operating experience information. The Operating Experience Tracking System is used to initiate and track operational events including recommended actions follow up. Six screens of the system contain diverse essential information which allows tracking of operational events and enables different kinds of browsing. OETS is a part of the NPP Krsko nuclear network system and can be easily accessed by all plant personnel. (author)

  18. Operator Performance Support System (OPSS)

    Conklin, Marlen Z.

    1993-01-01

    In the complex and fast reaction world of military operations, present technologies, combined with tactical situations, have flooded the operator with assorted information that he is expected to process instantly. As technologies progress, this flow of data and information have both guided and overwhelmed the operator. However, the technologies that have confounded many operators today can be used to assist him -- thus the Operator Performance Support Team. In this paper we propose an operator support station that incorporates the elements of Video and Image Databases, productivity Software, Interactive Computer Based Training, Hypertext/Hypermedia Databases, Expert Programs, and Human Factors Engineering. The Operator Performance Support System will provide the operator with an integrating on-line information/knowledge system that will guide expert or novice to correct systems operations. Although the OPSS is being developed for the Navy, the performance of the workforce in today's competitive industry is of major concern. The concepts presented in this paper which address ASW systems software design issues are also directly applicable to industry. the OPSS will propose practical applications in how to more closely align the relationships between technical knowledge and equipment operator performance.

  1. RA reactor operation, Annex A

    International Nuclear Information System (INIS)

    RA reactor was not operated during 1993, although it has been planned to exchange the complete instrumentation until the end of 1993, and to restart the reactor operation in the first half of 1993. This was not fulfilled because the instrumentation was not delivered until the end of 1993. Since our country is under international sanctions it is not possible to plan when the instrumentation will be delivered and foresee the precise date of reactor start-up. That is why this annex includes the plan of reactor operation for period of nine months starting from from the moment of start-up. It is planned to operate the reactor at 0.02 MW power first three months, to increase the power gradually and reach 3.5 MW after 8 months of operation. It is foreseen to operate the reactor at 4.7 MW from the tenth month on

  2. Organizational environment and operator culture

    International Nuclear Information System (INIS)

    The Nuclear Regulatory Commission has historically reviewed corporate and plant level management and organization against the criteria of NUREG-0800, The Standard Review Plan. These criteria address the organizational structure, management control, lines of authority and communication, the range and level of experience, and the availability of manpower to effectively and safely operate the facility. Now that most nuclear power plants have received their operating licenses, the emphasis for review has shifted to the day-to-day operation of the facilities. Along with this has come greater recognition that hardware and engineering systems, through vitally important, are not the only components needed for safe operation of power plants. The people who run and operate these plants are a vitally important component and are an integral part of the entire system, i.e., machinery does not operate in isolation

  3. Nuclear power plant operator licensing

    1981-07-01

    The objective of the Space Infrared (SIRE) Sensor program is to measure LWIR radiation of natural and man made sources in space. Measurements will be used to support development and operation of space based space surveillance systems. This paper describes the planned concept for operating SIRE as a non-deployed payload within the payload bay of the Orbiter. The operations concept is prefaced with an overview of the SIRE system addressing the sensor, space segment, ground segment and supporting elements of the Space Trans-portation System. This is followed by a description of operational concepts and data processing that will be used within the ground segment during flights to plan, command and evaluate SIRE operations. This responsive system provides for inflight evaluation of data and replanning of measurements as necessary to accommodate operational perturbations from the Orbiter and react to unexpected measurement results.

  6. Multi-unit operations considerations

    International Nuclear Information System (INIS)

    Several nuclear weapons programs have or are pursuing the implementation of multi-unit operations for tasks such as disassembly and inspection, and rebuild. A multi-unit operation is interpreted to mean the execution of nuclear explosive operating procedures in a single facility by two separate teams of technicians. The institution of a multi-unit operations program requires careful consideration of the tools, resources, and environment provided to the technicians carrying out the work. Therefore, a systematic approach is necessary to produce safe, secure, and reliable processes. In order to facilitate development of a more comprehensive multi-unit operations program, the current work details categorized issues that should be addressed prior to the implementation of multi-unit operations in a given weapons program. The issues have been organized into the following categories: local organizational conditions, work process flow/material handling/workplace configuration, ambient environmental conditions, documented safety analysis, and training

    The operating limits and conditions (OLCs) are operating parameters and conditions, chosen among all system/components, which, together, define the domain of the safe operation of ITER in all foreseen ITER states (operation, maintenance, commissioning). At the same time they are selected to guarantee the required operation flexibility which is a critical factor for the success of an experimental machine such as ITER. System and components that are important for personnel or public safety (safety important class, SIC) are identified considering their functional importance in the overall plant safety analysis. SIC classification has to be presented already in the preliminary safety analysis report and approved by the licensing authority before manufacturing and construction. OLCs comprise the safety limits that, if exceeded, could result in a potential safety hazard, the relevant settings that determine the intervention of SIC systems, and the operational limits on equipment which warn against or stop a functional deviation from a planned operational status that could challenge equipment and functions. Some operational conditions, e.g. in-Vacuum Vessel (VV) radioactive inventories, will be controlled through procedures. Operating experience from present tokamaks, in particular JET, and from nuclear plants, is considered to the maximum possible extent. This paper presents the guidelines for the development of the ITER OLCs with particular reference to safety limits.

Operations Research offers tools to optimize and find the best solutions to myriad decisions that managers have to take in their day to day operations or while carrying out strategic planning. Today, with the advent of operations research software, these tools can be applied by managers even without any knowledge of the mathematical techniques that underlie the solution procedures. The book starts with a brief introduction to various tool

  1. Reactor operations at SAFARI-1

    International Nuclear Information System (INIS)

    A vigorous commercial programme of isotope production and other radiation services has been followed by the SAFARI-1 research reactor over the past ten years - superimposed on the original purpose of the reactor to provide a basic tool for nuclear research, development and education to the country at an institutional level. A combination of the binding nature of the resulting contractual obligations and tighter regulatory control has demanded an equally vigorous programme of upgrading, replacement and renovation of many systems in order to improve the safety and reliability of the reactor. Not least among these changes is the more effective training and deployment of operations personnel that has been necessitated as the operational demands on the reactor evolved from five days per week to twenty four hours per day, seven days per week, with more than 300 days per year at full power. This paper briefly sketches the operational history of SAFARI-1 and then focuses on the training and structuring currently in place to meet the operational needs. There is a detailed step-by-step look at the operator?s career plan and pre-defined milestones. Shift work, especially the shift cycle, has a negative influence on the operator's career path development, especially due to his unavailability for training. Methods utilised to minimise this influence are presented. The increase of responsibilities regarding the operation of the reactor, ancillaries and experimental facilities as the operator progresses with his career are discussed. (author)

    2007-01-01

    This viewgraph presentation reviews the concept of the Operating System Abstraction Layer (OSAL) and its benefits. The OSAL is A small layer of software that allows programs to run on many different operating systems and hardware platforms It runs independent of the underlying OS & hardware and it is self-contained. The benefits of OSAL are that it removes dependencies from any one operating system, promotes portable, reusable flight software. It allows for Core Flight software (FSW) to be built for multiple processors and operating systems. The presentation discusses the functionality, the various OSAL releases, and describes the specifications.

  3. Spitzer Observatory Operations -- Increasing Efficiency in Mission Operations

    Science.gov (United States)

    Scott, Charles P.; Kahr, Bolinda E.; Sarrel, Marc A.

    2006-01-01

    This paper explores the how's and why's of the Spitzer Mission Operations System's (MOS) success, efficiency, and affordability in comparison to other observatory-class missions. MOS exploits today's flight, ground, and operations capabilities, embraces automation, and balances both risk and cost. With operational efficiency as the primary goal, MOS maintains a strong control process by translating lessons learned into efficiency improvements, thereby enabling the MOS processes, teams, and procedures to rapidly evolve from concept (through thorough validation) into in-flight implementation. Operational teaming, planning, and execution are designed to enable re-use. Mission changes, unforeseen events, and continuous improvement have often times forced us to learn to fly anew. Collaborative spacecraft operations and remote science and instrument teams have become well integrated, and worked together to improve and optimize each human, machine, and software-system element.

  9. A framework for operating experience

    International Nuclear Information System (INIS)

    The author provides an overview of the defence-in-depth reactor safety approach and outlines the major features of the framework in which the control room panel operator functions. Defence in depth assumes that occasional equipment failures will occur and people will make mistakes. Five overlapping thrusts are used to achieve public safety: reliable process systems, reliable safety systems, competent staff, multiple barriers; and the detection and correction of faults. The authorized control room operator, or first operator, in a CANDU nuclear power plant operates the systems and equipment of one unit in a multi-unit station in accordance with approved procedures. Operating activities include reactor startup, in-service routines and testing, in-service monitoring and inspection, correction of deviations from normal, and isolation, de-isolation, and testing of equipment prior to and following maintenance. The main features of the framework within which the first operator works are automatic control, the use of approved procedures, supervision by qualified senior staff, support from other operators and maintenance staff, and interaction with day support staff. Ontario Hydro's approach has resulted in an excellent record in employee safety, public safety, and operating performance

  10. Sequential operators in computability logic

    CERN Document Server

    Japaridze, Giorgi

    2007-01-01

    Computability logic (CL) (see http://www.cis.upenn.edu/~giorgi/cl.html) is a semantical platform and research program for redeveloping logic as a formal theory of computability, as opposed to the formal theory of truth which it has more traditionally been. Formulas in CL stand for (interactive) computational problems, understood as games between a machine and its environment; logical operators represent operations on such entities; and "truth" is understood as existence of an effective solution, i.e., of an algorithmic winning strategy. The formalism of CL is open-ended, and may undergo series of extensions as the study of the subject advances. The main groups of operators on which CL has been focused so far are the parallel, choice, branching, and blind operators. The present paper introduces a new important group of operators, called sequential. The latter come in the form of sequential conjunction and disjunction, sequential quantifiers, and sequential recurrences. As the name may suggest, the algorithmic ...

  11. Twist operators in higher dimensions

    CERN Document Server

    Hung, Ling-Yan; Smolkin, Michael

    2014-01-01

    We study twist operators in higher dimensional CFT's. In particular, we express their conformal dimension in terms of the energy density for the CFT in a particular thermal ensemble. We construct an expansion of the conformal dimension in power series around n=1, with n being replica parameter. We show that the coefficients in this expansion are determined by higher point correlations of the energy-momentum tensor. In particular, the first and second terms, i.e. the first and second derivatives of the scaling dimension, have a simple universal form. We test these results using holography and free field theory computations, finding agreement in both cases. We also consider the `operator product expansion' of spherical twist operators and finally, we examine the behaviour of correlators of twist operators with other operators in the limit n ->1.

  12. Development of autonomous operation system

    International Nuclear Information System (INIS)

    To enhance operation reliability of nuclear plants by removing human factors, study on an autonomous operation system has been carried out to substitute artificial intelligence (AI) for plant operators and, in addition, traditional controllers used in existing plants. For construction of the AI system, structurization of knowledge on the basis of the principles such as physical laws, function and structure of relevant objects and generalization of problem solving process are intended. A hierarchical distributed cooperative system configuration in employed because it is superior from the viewpoint of dynamical reorganization of system functions. This configuration is realized by an object-oriented multi-agent system. Construction of a prototype system was planned and the conceptual design was made for FBR plant in order to evaluate applicability of AI to the autonomous operation and to have a prospect for the realization of the system. The prototype system executes diagnosis, state evaluation, operation and control for the main plant subsystems. (author)

  13. RPC operation at high temperature

    Aielli, G; Cardarelli, R; Di Ciaccio, A; Di Stante, L; Liberti, B; Paoloni, A; Pastori, E; Santonico, R

    2003-01-01

    The resistive electrodes of RPCs utilised in several current experiments (ATLAS, CMS, ALICE, BABAR and ARGO) are made of phenolic /melaminic polymers, with room temperature resistivities ranging from 10**1**0 Omega cm, for high rate operation in avalanche mode, to 5 multiplied by 10**1**1 Omega cm, for streamer mode operation at low rate. The resistivity has however a strong temperature dependence, decreasing exponentially with increasing temperature. We have tested several RPCs with different electrode resistivities in avalanche as well as in streamer mode operation. The behaviours of the operating current and of the counting rate have been studied at different temperatures. Long-term operation has also been studied at T = 45 degree C and 35 degree C, respectively, for high and low resistivity electrodes RPCs.

  14. [Cleanliness in the operating room].

    Science.gov (United States)

    Suzuki, Toshiyasu

    2010-05-01

    With regard to recent findings in the cleanliness of the operating room, concerning handwashing and performing operations, the traditional method of excessive scrubbing using a brush is not effective, and handwashing using only an alcohol-containing antiseptic hand rub (rubbing method) has become common practice. Use of a brush has already been abolished in some medical institutions. In addition, sterilized water used for handwashing when performing operations has no scientific basis and use of tap water is considered sufficient. Furthermore, the concept of operating room zoning has also undergone a dramatic change. It was discovered that a layout focusing on work efficiency is more desirable than the one that follows an excessively rigid zoning pattern. One-footwear System not requiring change of shoes also has various advantages in improving the efficiency of the operation room, and this is thought to become commonplace in the future.

  15. Predictable response from MCR operators

    International Nuclear Information System (INIS)

    Operating Philosophy in a nuclear power plant is the driving influence that leads to obtaining a predictable response to any operating challenge in the Main Control Room. This means that for any event or abnormal situation in the plant, every operator will take the unit to the required state, every time. This is a must in our industry. This can be achieved by clearly identifying the challenges that face the operating staff. It is essential that a balanced review be done so that there is not over emphasis on any aspect of the operator's ability to respond. The major areas discussed in this presentation are Plant, Procedures and People. Discussion will bring focus to the use of procedures and how to identify good practices that require reinforcement at the simulator, and how to identify potential vulnerabilities. The three overheads will be reviewed to illustrate the systematic approach used at Darlington Nuclear. (author)

  17. Spectral computations for bounded operators

    CERN Document Server

    Ahues, Mario; Limaye, Balmohan

    2001-01-01

    Exact eigenvalues, eigenvectors, and principal vectors of operators with infinite dimensional ranges can rarely be found. Therefore, one must approximate such operators by finite rank operators, then solve the original eigenvalue problem approximately. Serving as both an outstanding text for graduate students and as a source of current results for research scientists, Spectral Computations for Bounded Operators addresses the issue of solving eigenvalue problems for operators on infinite dimensional spaces. From a review of classical spectral theory through concrete approximation techniques to finite dimensional situations that can be implemented on a computer, this volume illustrates the marriage of pure and applied mathematics. It contains a variety of recent developments, including a new type of approximation that encompasses a variety of approximation methods but is simple to verify in practice. It also suggests a new stopping criterion for the QR Method and outlines advances in both the iterative refineme...

  18. Hierarchies of incoherent quantum operations

    CERN Document Server

    Streltsov, Alexander; Bera, Manabendra Nath; Lewenstein, Maciej

    2015-01-01

    The search for a simple description of fundamental physical processes is an important part of quantum theory. One example for such an abstraction can be found in the distance lab paradigm: if two separated parties are connected via a classical channel, it is notoriously difficult to characterize all possible operations these parties can perform. This class of operations is widely known as local operations and classical communication (LOCC). Surprisingly, the situation becomes comparably simple if the more general class of separable operations is considered, a finding which has been extensively used in quantum information theory for many years. Here, we propose a related approach for the resource theory of quantum coherence, where two distant parties can only perform measurements which do not create coherence and can communicate their outcomes via a classical channel. We call this class local incoherent operations and classical communication (LICC). While the characterization of this class is also difficult in...

  19. Trends in operations strategy research

    Directory of Open Access Journals (Sweden)

    Ana Beatriz Lopes de Sousa Jabbour

    2009-12-01

    Full Text Available This article aims to identify research approaches in operations strategy research, with regards its content. From a systematic literature review we highlight the main definitions of operations strategy and discussions on competitive priorities and then, present the main focuses of the articles published in reputable journals nationally and internationally. It was identified that studies on the operations strategy followed in general the direction of relating the influence and the alignment of competitive priorities for structural and infrastructure decisions. And there are initiatives of studies, which derive from that, to relate the operations strategy in the context of supply chain, which in future may be an important trend. The results of this article bring insights on research trends in a subject with constant interest from researchers in the field of operations management.

    1993-01-01

    This report documents the results of the Airport Surface Operations Requirements Analysis (ASORA) study. This study was conducted in response to task 24 of NASA Contract NAS1-18027. This study is part of NASA LaRC's Low Visibility Surface Operations program, which is designed to eliminate the constraints on all-weather arrival/departure operations due to the airport/aircraft ground system. The goal of this program is to provide the capability for safe and efficient aircraft operations on the airport surface during low visibility conditions down to zero. The ASORA study objectives were to (1) develop requirements for operation on the airport surface in visibilities down to zero; (2) survey and evaluate likely technologies; (3) develop candidate concepts to meet the requirements; and (4) select the most suitable concept based on cost/benefit factors.
