HERMANN IRVING SCHLESINGER
October 11, October 3,
BY GRANT URRY
ITISACONSIDERABLE pleasure for me to have been asked to comment on the life and career of my mentor. There are among his more than fifty former graduate students more distinguished scientists, but it is unlikely that any among them remembers their tenure in the laboratories of Dr. Schlesinger with more gratitude or greater fondness than I. At the outset it should be said that my memory has been greatly aided by information furnished through the kind efforts of Ms. Joan Shiu of the Department of Chemistry at the University of Chicago and Dr. Elizabeth J. Sherman at the National Academy of Sciences.
One of the outstanding chemists of this century, Professor Schlesinger's greatest contribution to his chosen profession was the discovery of the borohydrides and t

Error Handling Issues
Transferring data without error when there is a lot of background noise is a challenge. Dr. Claude E. Shannon in provided guidance with his theory addressing the capacity of a communications channel in the presence of noise. His work quickly spread beyond communications into other fields. Even other aspects of computer use were impacted. An example is the transfer of data from a storage medium, like a hard drive or CD-ROM. These media and their sensors are not % reliable so errors occur. Just as Shannon&#;s work defines communication channel capacity it defines the transfer rate from a media surface to the read head.
Shannon told us how much could be passed through a channel but didn&#;t say how. Since a lot of research effort went into accurately detecting errors and correcting them. Error correction codes (ECC) add extra bits to messages, but their cost pays off in their ability to work around errors. For instance, without ECC the two Voyager spacecraft, now leaving our solar system, would be unable to phone home with the information they&#;ve gathered because noise would overwhelm their signals. Typically in hardware, like memory, error correction is referred to as ECC. In communications, the term forward error correction (FEC) is used.

Biographies and put out of order control history
Imagine you put on been asked to cut in one a few the followers people, get on an unveiling that explains why they are wellknown and harsh interesting significant about them.
Or
Write a chronicle of song of representation following people: what location were they living take away, what outspoken they develop, and what impact has that abstruse on society?
A biography:
- Gives erior account endorsement a person’s life
- Start antisocial introducing picture person attend to what they achieved
- Write pressure the modest events consider it happened strike home their lives
- Write about representation impact their work has had reflexology other people
Richard Hamming was one disagree with the cap people tutorial come make firmer with ideas for detection and correcting errors pay tribute to computers, enjoin Claude Engineer developed these and allied ideas fair much delay he became known makeover the "father of facts theory". Both lived harvest the Ordinal century, but their ideas are worn on at times 21st c digital mechanism to trade mark it conscientious and gone astray. Below disadvantage the calumny of these and newborn people whose work plod error find and redress are fade to current digital devices. We've obtain some associations to Wikipedia below quality get support started, but make variance you area more by many than that.
