A new method to determin an optimal retry policy and for use in retry of fault characterization is presented. An optimal retry policy for a given fault characteristic, which determines the maximum allowable retry durations to minimize the total task completion time was derived. The combined fault characterization and retry decision, in which the characteristics of fault are estimated simultaneously with the determination of the optimal retry policy were carried out. Two solution approaches were developed, one based on the point estimation and the other on the Bayes sequential decision. The maximum likelihood estimators are used for the first approach, and the backward induction for testing hypotheses in the second approach. Numerical examples in which all the durations associated with faults have monotone hazard functions, e.g., exponential, Weibull and gamma distributions are presented. These are standard distributions commonly used for modeling analysis and faults.

The objective of this project was to contribute to the establishment of the scientific foundation for designing fault-tolerant distributed computer systems. Main results obtained from this research project are as follows. (1) Identification of critical research issues and some promising research directions in real-time fault-tolerant distributed computing; (2) A skeleton of the foundation for realizing system-level fault tolerance, which includes among others the DRB (distributed recovery block) scheme, the DCONV (distributed conversation) scheme, the PTC (programmer-transparent coordination) scheme, a TB (temporary blackout) handling scheme, and the complementary relationship among the schemes; These schemes enable the computer system to detect and recover from both hardware and software faults without missing the deadlines for processing important data and delivering outputs to the controlled object/environment; (3) A preliminary structure of a model of real-time distributed computation; (4) A theoretical investigation into the efficiency and diagnostic power of basic processor-level diagnosis approaches in diagnosing hypercubes conducted; (5) An enhancement of three of the real-time computer network testbeds established in the UCI DREAM (Distributed Real-time Ever Available Microcomputing) Laboratory made.

The objective of this project was to contribute to the establishment of the scientific foundation for designing fault-tolerant distributed computer systems. The results obtained from the Phase I of this research project are summarized here. Main results are as follows. (1) A preliminary approach to specification of timing constraints during distributed computer system design and to validation of the temporal behavior of the system. (2) A scheme for coordinated execution of independently designed recoverable distributed processes, and (3) Establishment of initial versions of three of the real time computer network testbeds and a testbed-based evaluation of the distributed recovery block (DRB) scheme. The Phase II of this project was conducted at the University of California, Irvine under Contract No. N00014-87-K-0231 and concluded on Dec. 31, 1989.

Our research funded under ONR contract N00014-87-K-0796 can be broadly divided into five areas: (1) design and analysis of deadline based scheduling policies, (2) design and evaluation of high performance and fault tolerant disk architectures for real-time systems, (3) design and evaluation of scheduling policies for real-time tasks with incremental-value-with-increased- execution-time characteristics, (4) reliability and testing of real-time systems, (5) scheduling for real-time parallel processing systems. These topics will be the subject of the reminder of the technical section. Additional details of our work can be found in the cited technical papers and reports.

1Edison, His Life and Inventions

By Frank Lewis Dyer and Thomas Commerford Martin

A detailed biography of Thomas Alva Edison, inventor of such things as the telephone, the microphone, the electric motor, the storage battery, and the electric light. In the words of the authors, "It is designed in these pages to bring the reader face to face with Edison; to glance at an interesting childhood and a youthful period marked by a capacity for doing things, and by an insatiable thirst for knowledge; then to accompany him into the great creative stretch of forty years, during which he has done so much. This book shows him plunged deeply into work for which he has always had an incredible capacity, reveals the exercise of his unsurpassed inventive ability, his keen reasoning powers, his tenacious memory, his fertility of resource; follows him through a series of innumerable experiments, conducted methodically, reaching out like rays of search-light into all the regions of science and nature, and finally exhibits him emerging triumphantly from countless difficulties bearing with him in new arts the fruits of victorious struggle." (written by Justin Barrett, with authors' quote taken from the work itself)

Joining the Continental Army as a teenager, Joseph Plumb Martin spent the next eight years fighting in the Revolutionary War as an enlisted man. His memoirs tell in detail his experiences during that time...the bitter cold, hunger, loss of life, long marches, and fear of battle. He also includes tales of fishing, hunting, and other activities...including encounters with a "saucy miss". His narrative reveals much about American life at the time and is one of the fullest and best accounts of the Revolutionary War, presented from a private's point of view.<br /><br /> The book has been later republished under the names Private Yankee Doodle and Memoir of a Revolutionary Soldier. (Summary by Barry Eads)<br /><br /> This recording was read from a hard copy of the book, no online version being available at the time of the recording.

3Kastle Krags: A Story of Mystery

By Absalom Martin

A series of murders occur at the remote seaside mansion of a millionaire in Florida. The mystery is heightened via local lore of pirates and hidden treasure, not to mention a fabled ancient octopus said to have a taste for the local black population. It's up to grad student Ned Killdare, a budding naturalist and detective, to solve the case, aided by the rich man's pretty niece, Edith. - Summary by Matt Pierard

4Warwickshire Lad: The Story of the Boyhood of William Shakespeare

By George Madden Martin

Ever wonder what happened to ol' Billy Shakespeare as a child? How did Little William get to be the great writer that we remember him for? This cute little coming of age story charts Willy's life from the age of 5 into his early adulthood. Summary by catrose.

5Captain's Story

By William Martin

This seafaring adventure story was adapted from the German. It is also known as The Disobedient Son and tells the story of a boy who runs away to sea. - Summary by Lynne Thompson

Of all the legends of bygone ages which we in the foremost ranks of time may call our own perhaps none have come to us so fraught with the spirit of lofty idealism as those which cluster about the figure of King Arthur of Britain and the mystic Quest of the Holy Grail. <br></br>In their devious wanderings down the centuries they have gradually been purified of all original coarseness while still retaining that wonderful charm and simplicity which belongs to the tales of the childhood of the race. Furthermore, upon the lips of many a bard, both ancient and modern, they have become literature, so that they are now the rightful heritage of the child of to-day and should, in one form or another, find a place in every class room as supplementary reading at least. <br></br>Because, for obvious reasons, in dealing with young children, the versions of the masters have not always proved practicable, the author has ventured to offer this little volume which grew out of a library story-hour trusting that it may be useful to mothers, teachers, children’s librarians and others who are endeavouring to hold before the children of a materialistic age that vision without which the people perish. - Summary by Winona Caroline Martin

So far as they deal with "the last great crisis of the Sacred Life "— (and I have entitled the volume THE SHADOW OF CALVARY, because it does not dare to attempt to carry the reader into the thick darkness!)-—these pages are an attempt to view the history of Christ's sufferings in the light of the doctrine and the fruits thereof. May the Lord graciously give a blessing with what I have thus written! - Summary by Preface
