Measurement of k0 values for europium, lutetium and iridium at FRM II with a very well thermalized neutron spectrum
No full textABSTRACT: The k0 values of 6 non-1/v nuclides (152Eu, 152mEu, 154Eu, 177Lu, 192Ir and 194Ir) were determined using the extended Høgdahl formalism at the research reactor FRM II with very high f values. Standards were irradiated in 4 channels at different local temperatures between 40 °C and 55 °C measured using temperature sensitive irreversible labels. A good agreement with the recommended values was found for 152Eu, 154Eu and 177Lu using the original g(Tn) factors by Gryntakis, however, the k0 values for 152mEu in this work were 7% higher. New k0 values were also determined using the g(Tn) factors by Van Sluijs. Differences up to 6% were found for Eu isotopes compared with the recommended values. The recommended k0 values for 192Ir and 194Ir could be confirmed using g = 1. The theoretical k0 values for 177Lu were calculated using new nuclear data. They are up to 6% less than the recommended values. The present k0 values determined in this work showed a similar trend. The influence of different g(Tn) factors on the determination of the k0 values was investigated
The 2021 IAEA software intercomparison for k<sub>0</sub>-INAA
No full textIn order to establish the variation between results in mass fractions due to software implementation, as measured by the k0-method for INAA, the IAEA has organized a software intercomparison. A complete set of test spectra and associated information was assembled. Efficiency curves, neutron spectrum parameters, correction factors and mass fractions were calculated with the participating programs (k0-IPEN, k0-INRIM, k0-DALAT, k0-IAEA and KayWin) using identical peak areas. In this paper, we report on the observed discrepancies, causes, remedies and future software developments. The test data, as well as intermediate results and observed mass fractions of the certified reference material BCR-320R “channel sediment” are available through the IAEA on request. The variations in concentrations attributed to differences between the programs were initially found to be 5.6 and 7.9%, for certified and uncertified concentrations, respectively. After the certified concentrations had been made available to the participants and they had been allowed to improve their programs, the variations found were 2.7 and 3.4%, respectively. The main identified remaining causes of variation are differences in the procedures used for detector efficiency characterisation and neutron spectrum parameter determination.</p
Hardware implementation of digital signal processing algorithms for long distance pipeline inspections
No full textInspections on transmission pipelines in the petrochemical industry are regularly conducted in order to guarantee safety of operations. Inspection devices are sent through the lines to record sensor data, this data needs to be post-processed in order to be able to make an analysis on the state of the pipeline. In this thesis, existing software implementations of post-processing algorithms are taken and implemented in VHDL code. This code is synthesizable for implementation in a field programmable gate array (FPGA). Goal is to reduce the time require for post-processing. A test environment is implemented which is able to feed data to the FPGA and receive the processed data back. This environment consists of a Linux PC, which communicates in DMA mode over the PCI-Express bus to the FPGA. The test environment is functional, it shows a performance increase of eight to fourteen times compared to the software implementation. A proposal is made for speeding this up even more, by using concurrent processing on multiple processing nodes.Computer EngineeringCircuits and SystemsElectrical Engineering, Mathematics and Computer Scienc

Development of container transshipment port on Ihavandhippolhu Atoll, Maldives
No full textIhavandhippolhu is located on the most northern Atoll of the Maldives. There are two advantages of its location that are the reasons for this study on a container transshipment port. The first is the short distance to the main East-West shipping routes. Second, the central position in the Indian Ocean implies short feeder distances (see Figure 2). The exploitation of a transshipment port can generate more income for the Maldives besides the income from tourism. One of the problems for a new port would be the competition in the Indian Ocean; Colombo is expanding its port after congestion and Salalah is a new port that expands rapidly. To survive in this competitive environment, the new port has to perform well. This means efficient and fast cargo handling and low tariffs compared to the competitors. Especially the tariffs can be kept low, because the investment costs are expected to be quite low as well. The port is situated on a deep water atoll but protected against incoming offshore waves; a breakwater is probably not required and dredging costs can be limited. The main objective of this study is to investigate the technical and economical feasibility of a container transshipment port on Ihavandhippolhu Atoll on the Maldives.Civil Engineering and Geoscience
