This topic will be continuously discussed as the project proceeds. It has been discussed to submit an amended budget proposal by shortening the overall project period so that the part of the labor cost can be reallocated into the hardware budget. It seems the overall hardware budget (now re-estimated approximately as $35K) is higher than the one originally proposed (~$30K). Main hardware components have been specified and the first pricing quote has been received at the Norrfee Tech, AB. This process is currently being applied to all related components in data import, display, FFT, and the 2D-wavefield transformation module to generate the dispersion image data sets.
JFT2 TASK3 UPGRADE
The first task is to upgrade its capacity to handle the highest frequency from 30 KHz to 100 KHz.
JFT2 TASK3 SOFTWARE
Modification of the ParkSEIS software, the base software package to be developed into the software packaged for this HMA project, has started. A field data set collected by using the 48-channel MEMS microphones at the Lund University has been delivered to Park Seismic for the evaluation, by using the ParkSEIS MASW software package, of the optimum number of channels per longitudinal array (NCh-opt) and the optimum channel (receiver) spacing (dx-opt). The KGS format (a modified SEG-Y format) will be used A temporary data format, however, will be used as a communication tool to deliver data sets already collected by using a similar hardware system developed for other related projects at the Lund University until the hardware system for this project is fairly ready to be tested with the software package. Click for a brief demonstration of the new format on YouTube. Considering the vast amount of data that, when completed, will be coming from the acquisition system for the pseudo-real-time onboard analysis, there should be a compact data format without unnecessary overhead information that will allow the software package focus directly on the analysis algorithm rather than spending extra time for data importing. Choon Park) to maximize the downloading speed and compatibility between the current hardware design base (that uses the LabVIEW TDMS format) and the software development base (that uses the ParkSEIS format). Progress Table (Sub Contractor - Norrfee Tech) - January, 2020Ī new data format convention was proposed by the software developer (Dr. Progress Table (Prime Contractor - Park Seismic LLC) - January, 2020 Monthly Project Meeting (January 28, 2020) ( Minutes) Kickoff and Technical Advisory Panel (TAP) Meeting (January 23, 2020) ( Minutes) Project administration and management aspects (e.g., communication method, scheduling, monthly invoicing, reporting, and payment, etc.) have been heavily discussed and executed throughout the entire month. Temperature calibration, which may be necessary during the dispersion analysis of Lamb waves, was briefly discussed as the topic was raised during the TAP meeting as a potential issue. Technical and administrative contents of the project were prepared to present during the Kickoff and the 1st TAP (Technical Advisory Panel) meeting scheduled on January 23, 2020. This blog will be open only among the project participants.
A blog was also to be prepared soon as a means to post each participant's outcomes for mutual communication and calibration purposes. A dedicated web site (this HMA site) was planned to open soon for public access. Communication methods among all participants were discussed. Early clarification of potential issues in the hardware, software, administrative, and budgetary aspects has been attempted. Blueprints for hardware system building and software package development were prepared. General frameworks of the hardware and software were drafted. As each participant was revisiting the original project proposal, scope of work, description of tasks, and the project schedule, technical contents and the overall work flowchart were discussed for clarification of assigned tasks and interaction with other participants' tasks. The project officially started as of January 6, 2020.
