The Procedure for Determining and Quality Assurance Program for the Calculation of Dose Coefficients Using DCAL Software

The development of a spallation neutron source with a mercury target may lead to the production of rare radionuclides. The dose coefficients for many of these radionuclides have not yet been published. A collaboration of universities and national labs has taken on the task of calculating dose coefficients for the rare radionuclides using the software package: DCAL. The working group developed a procedure for calculating dose coefficients and a quality assurance (QA) program to verify the calculations completed. The first portion of this QA program was to verify that each participating group could independently reproduce the dose coefficients for a known set of radionuclides. The second effort was to divide the group of radionuclides among the independent participants in a manner that assured that each radionuclide would be redundantly and independently calculated. The final aspect of this program was to resolve any discrepancies arising among the participants as a group of the whole. The output of the various software programs for six QA radionuclides, 144Nd, 201Au, 50V, 61Co, 41Ar, and 38S were compared among all members of the working group. Initially, a few differences in outputs were identified. This exercise identified weaknesses in the procedure, which have since been revised. After the revisions, dose coefficients were calculated and compared to published dose coefficients with good agreement. The present efforts involve generating dose coefficients for the rare radionuclides anticipated to be produced from the spallation neutron source should a mercury target be employed

An Interdatabase Comparison of Nuclear Decay and Structure Data Utilized in the Calculation of Dose Coefficients for Radionuclides Produced in a Spallation Neutron Source

Internal and external dose coefficient values have been calculated for 14 anthropogenic radionuclides which are not currently presented in Federal Guidance Reports Nos. 11, 12, and 13 or Publications 68 and 72 of the International Commission on Radiological Protection. Internal dose coefficient values are reported for inhalation and ingestion of 1 μm and 5 μm AMAD particulates along with the f1 values and absorption types for the adult worker. Internal dose coefficient values are also reported for inhalation and ingestion of 1 μm AMAD particulates as well as the f1 values and absorption types for members of the public. Additionally, external dose coefficient values for air submersion, exposure to contaminated ground surface, and exposure to soil contaminated to an infinite depth are also presented. Information obtained from this study will be used to support the siting and permitting of future accelerator-driven nuclear initiatives within the U.S. Department of Energy complex, including the Spallation Neutron Source (SNS) and Accelerator Production of Tritium (APT) Projects

Принципы построения системы комплексного информационного обслуживания сотрудников предприятия рецептурного производства

This paper discusses further applications of the ontology-based approach to the design of batch manufacturing enterprises. It involves, among other things, standards formalization. This paper, in particular, is dedicated to graphical representation of Piping and Instrumentation Diagram (P&ID) and Procedure Function Chart (PFC) languages, as per ISA-88 standard. They form a toolkit for automation engineer to work with. Contingency analysis and information retrieval agents were implemented. The article also discusses agent-oriented approach to robot interaction in robotic production systems, that is conducted via shared semantic memory

An approach to speech ambiguities eliminating using semantically-acoustical analysis

An approach to the problem of elimination of ambiguities in speech messages by application of semantically- acoustical analysis is presented in this paper. Authors propose the architecture of the intelligent system that implements this principle. According to this principle the direct transition from speaking to meaning of given phrase is possible with the help of digital signal processing techniques, as well as knowledge formalization methods using semantics networks (semantically- acoustical analysis). A prototype of intelligent system to resolve speech ambiguities of a certain type (homonyms and paronyms) based on the tools provided by the OSTIS technology and GUSLY signal processing framework has been implemented. The main advantages of the proposed solution in comparison to the standard automatic speech recognition systems and possible ways of further development for natural language understanding problem are also reported in this pape

Design of batch manufacturing enterprises in the context of Industry 4.0

This paper presents an evolution of an ontology- based approach to designing batch manufacturing enterprises. According to Industry 4.0 approach, instead of isolated view of a manufacturing process inside a single enterprise this new approach encompasses related business entities as well - raw material suppliers (e.g. dairy farms) and large-scale consumers (e.g. stores or retail chains). Special attention is paid to logistics processes: a short description of fundamental logistics processes of cottage cheese production is provided, as well as subject do- main structure of logistics and an example of formal specification of emergency logistics situation. It is shown that multiagent indus- trial control system with agents interacting via shared memory is compliant with design principles of Industry 4.0 approach. Standards formalization topic is touched upon as well. PFC, a graphical procedural model specification language, formalization is discussed. PFC is specified in ISA-88.02 standard. Graphical language formalization allows industrial control system users to communicate to it in a unified manner using diagrams that are widely understood by engineering specialists. This paper also outlines an agent-oriented approach to robot interaction within industrial robotic complexes based on shared semantic memory interaction mechanism
