Novos códigos quaternários obtidos de um algoritmo de otimização combinatorial New quaternary codes obtained from a combinatorial optimization algorithm

Acta Scientiarum: Technology, 1999
Novos códigos sobre Z4 (o anel dos integrais módulo 4) encontrados através da utilização de um algoritmo de otimização combinatorial são tabulados. Também apresentamos, entre estes códigos, um novo código Z4- linear melhor do que qualquer código binário ...

Adaptive Minimum-BER Linear Multiuser Detection for DS-CDMA Signals in Multipath Channels

, 2001
The problem of constructing adaptive minimum bit error rate (MBER) linear multiuser detectors is considered for direct-sequence code division multiple access (DS-CDMA) signals transmitted through multipath channels.

Safety of Prescription Nonsteroidal Anti‐inflammatory Drugs in Adults With Inflammatory Bowel Disease: Data From a Large Administrative Claims Cohort

Arthritis Care &Research, EarlyView.
Objective The concern that nonsteroidal anti‐inflammatory drugs (NSAIDs) may precipitate flares of inflammatory bowel disease (IBD) has limited their use in managing musculoskeletal symptoms in those with IBD, but safety data are mixed. Methods This retrospective cohort study included patients with IBD aged at least 18 years from Optum's deidentified ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

The Poincaré Polynomial of a Linear Code [PDF]

, 2018
Producción CientíficaWe introduce the Poincar´e polynomial of a linear q-ary code and its relation to the corresponding weight enumerator. We prove that the Poincar´e polynomial is a complete invariant of the code in the binary and ternary case and it ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.
