Design And Learning-Based Decoding Of Low-Density-Parity-Check Codes For Multiterminal Communication, Salman Habib

Dissertations

The field of information theory was initiated by Claude Shannon in 1948. According to his most notable work, data can be transmitted reliably over a noisy communication channel with high probability, as long as a suitable coding scheme is employed to protect the data from channel noise. Since then, coding theorists have made numerous attempts to design low-complexity error correcting schemes which achieve the Shannon limit.

In the 1960s, Robert Gallager introduced sparse graph-based low-density-parity-check (LDPC) codes which are practically suitable for various coding applications, mainly due to their low encoding and decoding complexity compared to classical codes (e.g., Reed-Muller …

From An International English Language Assessment Framework To A Teacher-Based Assessment: A Study Of Primary English Teachers' Agentive Perspectives And Projections, Santi Farmasari

REID (Research and Evaluation in Education)

This study explores four primary English teachers' agentive perspectives about assessment in their schools. Given the challenges brought by the abolition of International Standard School (ISS), the changed status of the school, and the exclusion of English from the 2013 National Education Curriculum (NEC), a teacher-based assessment was the only solution to the unavailability of assessment guidelines and the unsuitability of assessment materials and methods. Employing teacher agency theory, this study examines the agentive sides of the teachers' perspectives as they would represent the teachers' strategic solutions toward the school's emerging problems. The teacher-based assessment was expected to accommodate the …

In The Name Of Diversity: Why Mandatory Diversity Statements Violate The First Amendment And Reduce Intellectual Diversity In Academia, Daniel M. Ortner

Catholic University Law Review

In the 1950s and 1960s in many parts of the country, a professor could be fired or never hired if he refused to denounce communism or declare loyalty to the United States Constitution. The University of California system took the lead in enforcing these loyalty oaths. These loyalty oaths were challenged all the way up to the United States Supreme Court and were soundly rejected, establishing the centrality of academic freedom and open inquiry on the university campus. So why are loyalty oaths making their resurgence in the form of mandatory diversity statements? Universities have begun requiring faculty members to …
