Abstract:
Rivers in Central and Eastern Europe are highly polluted as a result of over-industrialization, resource intensive production processes and lax environmental enforcement. At the beginning of the economic transition, great optimism abounded within the region that environmental problems would be dealt with early and that the West would offer significant financial help. It is now clear that achieving significant improvement in environmental quality will require many years and will be largely financed from internal resources. Moreover, the region's goal of joining the European Union dominates the environmental policy agenda. Drawing upon the results of a three year study conducted at the International Institute for Applied Systems Analysis (IIASA), cost-effective strategies for eventually achieving this goal are identified. The paper discusses recommendations for implementing these strategies within the evolving political and economic environment of Central and Eastern Europe.

Abstract:
A literature review on water quality management optimization models is presented. They include linear and non-linear approaches, deterministic and stochastic methods, as well as multi-criteria decision techniques. Two river basin decision support systems, DESERT and STREAMPLAN developed recently at the International Institute of Applied Systems Analysis, (IIASA) are outlined. The usage of these tools is illustrated by results obtained for three river basins located in Central and Eastern European countries. Examples incorporate least-cost DO policies, regional strategies to reduce nutrient emissions with special regard to the control of inland sea eutrophication, multi-criteria decision making and the sequential usage of optimization and simulation models to assess the sensitivity of a particular policy in terms of water quality and economic impacts. Major features of available optimization models are classified. Reasons of their rare real life applications and associated barriers are evaluated, primarily the nature of legislation and related institutional structures. Finally, a future outlook is presented.

Abstract:
This paper presents the major features of two decision support systems (DSS) for river water quality modeling and policy analysis recently developed at the International Institute of Applied Systems Analysis (IIASA), DESERT and STREAMPLAN. DESERT integrates in a single package data management, model calibration, simulation, optimization and presentation of results. DESERT has the flexibility to allow the specification of both alternative water quality models and flow hydraulics for different branches of the same river basin. Specification of these models can be done interactively through Microsoft® Windows commands and menus and an easy to use interpreted language. Detailed analysis of the effects of parameter uncertainty on water quality results is integrated into DESERT. STREAMPLAN, on the other hand, is an integrated, easy-to-use software system for analyzing alternative water quality management policies on a river basin level. These policies include uniform emission reduction and effluent standard based strategies, ambient water quality and least-cost strategies, total emission reduction under minimized costs, mixed strategies, local and regional policies, and strategies with economic instruments. A distinctive feature of STREAMPLAN is the integration of a detailed model of municipal wastewater generation with a water quality model and policy analysis tools on a river basin scale.

Abstract:
AbstractIn recent years, new non-invasive brain stimulation techniques are appearing which, based on neuromodulation, allow the treatment of pathologies such as pain or depression. One of the target regions where these techniques are usually applied is in the dorsolateral prefrontal cortex (DLPFC) and the result of these procedures depends on the correct and precise location of the point on the scalp close to this region. According to the literature, the most common methods that are currently used for the localization of the DLPFC are the Neuroimaging and Neuronaviagtion Systems, the 5cm method, the BeamF3 method and the international 10–20 System. Montreal Neurological Institute (MNI) space is a 3-dimensional coordinate system (also known as ‘atlas’) of the human brain, used to map the location of brain regions independent of individual differences in the size and overall shape of the brain. This study reviews the published articles that attempt to locate DLPFC positions, evaluate the discrepancies and quantify the differences among different authors.

Abstract:
This chapter details the establishment of International Institute for Applied Systems Analysis (IIASA) to demonstrate the crucial role of East-West cooperation in shaping global governance. IIASA as a diplomatic initiative was the result of actions by top governmental officials: US president Lyndon Johnson proposed creating an East-West think tank and Soviet Prime Minister Aleksei Kosygin accepted his proposal, both sides considering this step as part of cultural diplomacy or an exercise of “soft power” in the presumably less ideological areas of science and technology. The chapter then suggests that the establishment of IIASA can be interpreted as precisely such a forward-oriented arrangement to enable a certain form of cooperation between the opposing great powers: mutual predictability was enhanced by bringing together leading policy scientists from East and West, whereas shared goals were articulated through applied systems research.

Abstract:
The preceding chapters have all contributed to building the knowledge base for the actual Wittgenstein Centre for Demography and Global Human Capital (WIC) projections that will be presented and discussed in the second part of this book. This chapter stands as a bridge between the two parts. Its focus is the translation and operationalization of the empirical evidence and the substantive arguments presented so far into specific population projections by age, sex, and level of educational attainment for all countries in the world. This is a complex exercise in which data and methodology play the crucial roles. The cohort–component multidimensional projections presented in this volume require a large amount of information, ranging from base-year data on population disaggregated by levels of educational attainment by age and sex, to data on fertility, mortality, and migration by age, sex, and education for the base year, and, finally, to the assumed numerical values of these determinants according to the different scenarios. This new set of expert argument-based projections by age, sex, and educational attainment presents an important new step at the forefront of international population projections. As discussed in Chapter 1, this is a logical next step in the tradition of international population projections by the World Population Program of the International Institute for Applied Systems Analysis (IIASA). This effort also goes beyond what the United Nations (UN) and other agencies have been doing in two important ways: it provides the most comprehensive and systematic summary of expert knowledge on future fertility, mortality, and migration to date—including the input of hundreds of demographers from around the world—and it translates this into the most comprehensive set of human capital projections for 195 countries. The WIC projections cover all countries in the world with more than 100,000 inhabitants. In this effort, the study builds on and significantly expands earlier IIASA reconstructions and projections of the population by age, sex, and educational attainment for 120 countries published in 2007 and 2010 (KC et al., 2010; Lutz et al., 2007).

Abstract:
As robot systems become increasingly prevalent in manufacturing environments, the need for improved accuracy continues to grow. Recent accuracy improvements have greatly enhanced automotive and aerospace manufacturing capabilities, including high-precision assembly, two-sided drilling and fastening, material removal, automated fiber placement, and in-process inspection. The accuracy requirement of those applications is primarily a function of two main criteria: (1) The pose accuracy (position and orientation accuracy) of a robot system’s tool center position (TCP), and (2) the ability of a robot system’s TCP to remain in position or on-path when loads are applied. The degradation of a robot system’s tool center accuracy can lead to a decrease in manufacturing quality and production efficiency. Given the high output rate of production lines, it is critical to develop technologies to verify and validate robot systems’ health assessment techniques, particularly the accuracy degradation. In this paper, the National Institute of Standards and Technology’s (NIST) effort to develop the measurement science to support the monitoring, diagnostics, and prognostics (collectively known as prognostics and health management (PHM)) of robot accuracy degradation is presented. This discussion includes the modeling and algorithm development for the test method, the advanced sensor development to measure 7-D information (time, X, Y, Z, roll, pitch, and yaw), and algorithms to analyze the data.

Abstract:
In industry, the analysis of near miss events can support the improvement of safety on the workplace. Near miss events are usually defined as near accidents, unsafe acts or conditions, that did not cause significant harm to people and goods, but under slightly different circumstances could have turned into accidents. Near miss analysis can help companies to identify possible causes of adverse events and work to prevent future accidents, representing an important source for verifying the effectiveness of the safety management process. The adoption of near miss management systems (NMSs) is mostly diffused in sectors where safety is a crucial issue (e.g., mining, construction, nuclear, aviation, etc.), but it could be an important resource in other contexts as well. The aim of this work is to identify some of the main barriers and drivers for the implementation of NMSs, investigating on one side the reasons that keep companies from adopting NMSs, on the other side the possible actions that could help spreading the use of this tool. The study presents the results of an exploratory survey carried out in collaboration with the Italian National Institute for Insurance against Accidents at Work (INAIL), which included a sample of Italian companies from different sectors. The results presented can help identifying the main criticalities to address to support the diffusion of NMSs.

Abstract:
According to the results of the HRA comparison study by USNRC and Halden, the evaluation results are significantly different when comparing the method calculations alone, comparing the experiments alone, and further comparing the method and experiment trends [1]. It is considered that human correspondence characteristics have a large context dependency in plant behavior and operator cognitive mechanism variety, however they are not properly captured. It is said that experiments are required to understand cognitive processes and contexts, and models are required to develop evaluation methods that take cognitive mechanisms and context dependencies into consideration. These data and conclusions, which must be true, are still startling facts. Here, we will examine three comparative studies1.Cognitive Process Analysis Experiment (in House): Joint study of Japanese BWR utilities and vendors. When we estimate Human Error Probabilities including Time Reliability Correlation, we must remind its dependency of accident scenario, culture, crew type, etc. Some insights are useful for HRA method consideration [2].2.Three HRA Model Comparison (in House): Two representative HFEs from two types of reactors in Japan, Pressurized Water Reactor (PWR) and Boiling Water Reactor (BWR), were chosen [3]. HRA method to be used are THERP method, Electric Power Research Institute (EPRI) method, and IDHEAS method [4-6] For both PWR and BWR examples, different HEPs were obtained by different HRA methods also. The scenario analysis, qualitative analysis, and task analysis must be reflected into HEPs.3.USNRC & Halden Model & Experiment Comparison: The model is judged to be underestimated compared to the experiment in one accident scenario and another case, to be overestimated. The dispersion of the calculation results by the method and experimental results are close to three digits [1, 7]. The importance of qualitative scenario analysis was widely recognized, and it became clear that the level of analysis depends largely on the knowledge and experience of analysts. This is because the lack of clear guidance in the HRA methodology has led to discrepancies in the analyst's approach [7].References[1] U.S. Nuclear Regulatory Commission, The International HRA Empirical Study, Lessons Learned from Comparing HRA Methods Predictions to HAMMLAB Simulator Data, NUREG-2127, August 2014.

Abstract:
In recent years, organizations both at home and abroad are actively carrying out a research on the Molten Salt Reactor systems (MSRs). For example, the Shanghai Institute of Applied Physics (SINAP), Chinese Academy of Science (CAS), is currently involved in the design and development of a 10MWth Solid Fuel Thorium Molten Salt Reactor (TMSR-SF1). SINAP started their analysis of TMSR using an earlier version of RELAP/SCDAPSIM, MOD4.0. MOD4.0 included models and correlations for molten salts but was unable to treat molten salts in the presence of non-condensable gases. Since that time SINAP and ISS have worked in parallel to extend the models and correlations for such systems. The SINAP modified code, using SINAP proprietary models and correlations, is described in the “open literature” under the name RELAP5-MSR. More general, but comparable, models developed by ISS for liquid metals/salts in the presence of non-condensable have been incorporated into RELAP/SCDAPSIM/MOD4.1. This extended option is currently being implemented for Li-Pb, Pb-Bi, molten salts, and Na.

Abstract:
This study was performed at the Institute for Neutron Physics and Reactor Technology at Karlsruhe Institute of Technology and is addressed to establish the combined usage of the best-estimate code TRACE and the uncertainty and sensitivity analysis tool SUSA, for safety related investigations of current and future nuclear energy systems. In the frame of this paper the applicability to supercritical water related investigations is covered. Several Nusselt correlation for the heat transfer to supercritical water are available and have been evaluated in previous investigations but not one of them gave satisfying results. Hence, the consideration of uncertainty and sensitivity measures applied to the topic of heat transfer seems to be an appropriate way. In a first step a post-test analysis of an experiment was conducted. Results showed that with the help of uncertainty and sensitivity methods parameters which affect the results most could be identified. The most important parameter was of course the Nusselt correlation. In addition to the identification of important parameters, the experimental results were enveloped by the calculated results. That means, in the sense of safety related evaluation of designs for reactors operated with supercritical water, that key parameters (cladding temperature) can be calculated with a certain confidence.

Abstract:
In this paper we present an analysis and comparison of two streamwise supersonic vortices interaction with using the methods of maximum vorticity and the ?2-criterion. Mach number of incoming flow was M? = 3. A pair of vortices was generated by two coaxial straight wings with sharp leading, tip and trailing edges. Two configurations are considered: a pair of counter-rotating vortices and a pair of co-rotating vortices. In the case of counterrotating vortices the wings attack angle was 10 degrees. In the case of co-rotating vortices the attack angle of one of the wings was 10 degrees, the attack angle of other one was -10 degrees. Numerical data were obtained in the domain of 10 wing chords downstream from a wings axis by a computational model based on the URANS equations with SA turbulence model. Numerical simulations were performed on the hybrid supercomputing system K-60 at the Keldysh Institute of Applied Mathematics RAS using the developed software package ARES for 3D turbulent flows modeling on high performance computing systems. The main simulation was performed on 224 cores. The simulations were carried out on unstructured grids with hexagonal cells.

Abstract:
Operators of longwall mining systems experience sound levels of 93–105 dB(A) and receive noise exposures that place them at risk of noise-induced hearing loss. To address the problem, the National Institute for Occupational Safety and Health (NIOSH*) Office of Mine Safety and Health Research (OMSHR) has conducted research to develop engineering noise controls for longwall systems. In previous field surveys, the sound radiated by the cutting drums was identified as a major hazard, especially considering their close proximity to the operators. Cutting drums are complex structures consisting of curved metal pieces welded together, and NIOSH has used modeling and simulation to characterize the acoustic properties of this structure. Based on a finite element (FE) model of the drum, the boundary element method (BEM) was used to predict the sound radiated from the vibrating drum due to an excitation force applied to one of the cutting bits. Simulations were used to examine the following with respect to the radiated sound power: (1) the ramifications of adding the welds to the model rather than assuming direct attachment between the metal components; (2) the effect of weld stiffness; (3) the relative contributions of the vanes and the cylindrical part of the drum; and (4) the sensitivity to the direction of the applied force. Parametric studies have shown that including the weld in the finite element model has a significant effect on the predicted sound power level, while varying the weld Young’s modulus by 20% does not radically change the sound radiation. Panel contribution analysis indicates that the vanes contribute much more to the total sound power level, as compared to the cylindrical part of the drum. Consequently, it is expected that damping treatments would be most effective at controlling noise radiation if applied to the vanes rather than to the cylindrical portion. Finally, case study results show that the sound power levels are most sensitive to the tangential and bending forces above 500 Hz. For frequencies below 500 Hz, the sound power level is most sensitive to axial and bending forces.

Abstract:
Fluoride-salt-cooled, high-temperature reactor (FHR) technology combines the robust coated particle fuel of high-temperature, gas-cooled reactors with the single phase, high volumetric heat capacity coolant of molten salt reactors and the low-pressure pool-type reactor configuration of sodium fast reactors. This paper discusses one key technology area required to further define and develop the FHR: the thermal hydraulic performance of the core, primary system and second loop. Shanghai Institute of Applied Physics (SINAP) is leading the China Academy of Science (CAS) FHR program. A TMSR-SF1 reactor with a fluoride cooled pebble bed design has been suggested by SINAP, and the design is currently in progress. For this preliminary thermal hydraulic assessment, a TMSR-SF1 system model was developed using RELAP5. The RELAP5 model was used to help define and size systems such as the intermediate coolant salt selecting. A loss of flow transient was also simulated to evaluate the performance of the reactor during an anticipated transient event. A steady-state calculation was carried out and the calculated initial conditions show the influence of different salt. The loss of forced flow (LOFF) transient simulation results show that the passive residual heat removal system can effectively remove all decay heat from the primary loop under this extreme accident scenario. Some initial recommendations for modifying system component designs, such as heat exchanger with different salt and install place of pump, are also discussed.

Abstract:
Under ISO/IEC 17025, the laboratories are generally required to participate in interlaboratory comparisons or proficiency testing to maintain their high competence and assure the quality of results for establishing the effectiveness and comparability of calibrations. Participation in proficiency testing to assure the good performance and capabilities is the basic requirement for laboratories in Taiwan to apply for accreditation certification or seek an extension of the certification issued by Taiwan Accreditation Foundation (TAF), the main accreditation body in Taiwan. When the proficiency testing is not available, the calibration laboratories in Taiwan shall participate in the measurement audits under the requirement of TAF. The Center for Measurement Standards of Industrial Technology Research Institute (CMS/ITRI) not only organize the proficiency testing programs regularly but also provide the measurement audits to meet the needs of the calibration laboratories that apply for the new accreditation items. In the last two years, the tests of energy efficiency of compressed air systems were required by law, digital pressure gauge calibration services are urgently demanded in industry. In order to expand their measurement scopes to include the digital pressure gauge calibration, 11 laboratories applied for measurement audits with the CMS/ITRI since there was no proficiency testing program for digital pressure gauge calibration. In these audits, the National Measurement Laboratory (NML) provided the reference values for the digital pressure gauges. In this paper, the results of interlaboratory comparisons for 11 laboratories were analyzed based on the outcomes of the measurement audits. Through the statistical analysis, the comparison results showed reasonable agreements in general among the measurements on digital pressure gauge calibration for most of calibration laboratories. It can also be found in this analysis that the measurement audits can be used in confirming the competence of the laboratories and provide solid proof for accreditation purpose.
