Lloyd Richard Welch (September 28, 1927 – December 28, 2023) was an American information theorist and applied mathematician, and co-inventor of the Baum–Welch algorithm and the Berlekamp–Welch algorithm, also known as the Welch–Berlekamp algorithm. Welch received his B.S. in mathematics from the University of Illinois, 1951, and Ph.D. in mathematics from the California Institute of Technology, 1958, under advisor Frederic Bohnenblust. He worked at the Jet Propulsion Laboratory 1956–1959, Institute for Defense Analyses in Princeton, 1959–1965, and University of Southern California, 1965–1999. He was elected a member of the National Academy of Engineering in 1979 for "contributions to an understanding of possibilities, limitations, and design of communications coding for reliability, security, and synchronization". He was also an IEEE Fellow, and received the 2003 Claude E. Shannon Award The Claude E. Shannon Award of the IEEE Information Theory Society was creat ...

Murders Of Katherine And Sheila Lyon
The murders of Katherine and Sheila Lyon are the abduction, sexual abuse and murder of two sisters — aged 10 and 12 respectively — who disappeared from a shopping center in Wheaton, Maryland, on March 25, 1975. Described as a crime which shattered the innocence of the suburbs of Maryland, the disappearance of Katherine and Sheila Lyon initiated one of the largest police investigations in the history of the Washington metropolitan area, although their fate would remain unknown for thirty-eight years, by which time their disappearance had long become a cold case. A re-investigation of the sisters' disappearance in 2013 led detectives to charge a convicted child sex offender named Lloyd Lee Welch, Jr. with the first-degree murder of the Lyon sisters. Welch was indicted for their murders in July 2015; he pleaded guilty to two counts of first-degree murder in September 2017 via a plea bargain in which he admitted to participating in the girls' abduction, but not their sexual as ...

University Of Illinois Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars".

Institute For Defense Analyses
The Institute for Defense Analyses (IDA) is an American non-profit corporation that administers three federally funded research and development centers (FFRDCs) – the Systems and Analyses Center (SAC), the Science and Technology Policy Institute (STPI), and the Center for Communications and Computing (C&C) – to assist the United States government in addressing national security issues, particularly those requiring scientific and technical expertise. It is headquartered in Alexandria, Virginia. History Two ideas critical to the birth of the Institute for Defense Analyses, also known as IDA, emerged from World War II. The first was the necessity for unifying the several services into a single, coordinated department. The second was the realization of the strength of the relationship between science—and scientists—and national security. The first reached fruition when President Harry Truman signed the National Security Acts of 1947 and 1949, creating the Department of Defense ...
