Integrated Petrophysics and Rock Physics Results and Log QC and Editing in Deep HPHT Chlorite-Rich Wilcox Sands, Fandango Field, South Texas – A Case Study

SPWLA 64th Annual Symposium Transactions, 2023
This work uses an integrated petrophysics-rock physics workflow to simultaneously evaluate formation volumes (e.g., porosity and lithology) and edit well logs in high-porosity and high-permeability chlorite-cemented Wilcox sands in deep, high-temperature, high-pressure wells of South Texas, USA, Fandango Field. Data include standard logging suites plus

Constructing QC-LDPC codes based on dimension reduction for physical layer security

2019 IEEE Symposium on Computers and Communications (ISCC), 2019
As a recently proposed physical layer security scheme, the two-dimensional transmission scheme prevents eavesdropping, but the bit error rate (BER) of the receiver becomes high. A new coding scheme for Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) codes to improve the performance of the receiver is proposed and named as dimension reduction coding ...

Third generation anthropomorphic physical phantom for mammography and DBT: incorporating voxelized 3D printing and uniform chest wall QC region

SPIE Proceedings, 2017
Physical breast phantoms provide a standard method to test, optimize, and develop clinical mammography systems, including new digital breast tomosynthesis (DBT) systems. In previous work, we produced an anthropomorphic phantom based on 500x500x500 μm breast CT data using commercial 3D printing. We now introduce an improved phantom based on a new cohort

Study on the Effectiveness of QA/QC Methods for Non-physical Wedges by Comparing EPID and 2D Array Detector Beam Profiles

Japanese Journal of Radiological Technology
Beam profiles of enhanced dynamic wedge (EDW), a non-physical wedge, were obtained using EPID and 2D array detector, and the effectiveness of the QA/QC method for EDW using EPID was investigated.Using a radiotherapy unit (Clinac iX; Varian Medical Systems, Palo Alto, CA, USA), the EDW beam profile was measured 10 times with an EPID (aS1000; Varian ...
