Liturgy and Ecumenism: What Next?

(Excerpt) This year, 1998, marks the twentieth anniversary of the Lutheran Book of Worship (LBW) that we celebrate together with the fiftieth anniversary of the Institute of Liturgical Studies here at Valparaiso University. My personal debt to the institute goes back to 1956 when I persuaded my internship supervisor to allow me to attend the institute in Michigan. That meeting introduced me to some of the giants of the previous generation-Arthur Carl Piepkorn, Berthold von Schenk, AR. Kretzmann and M. Alfred Bichsel-and gave me a vision of what worship among Lutherans might be. Then, following my return from doctoral studies at the University of Heidelberg, I was invited to present a paper at the 1961 institute. It was on the concept of anamnesis, prescient of this year\u27s eschatological theme. And now, after fifteen years as an ex-patriot, you have invited me back. I am grateful

Toward the Renewal of Christian Initiation in the Parish

(Excerpt) The brochure for this year\u27s Institute contained the arresting sentence: To discuss the question of Christian initiation is, finally, to inquire after the very nature of the church: the issue is of vast ecclesiological significance. The renewed and growing interest in Christian initiation is prompted by a new vision of the church

Application of flight systems methodologies to the validation of knowledge-based systems

Flight and mission-critical systems are verified, qualified for flight, and validated using well-known and well-established techniques. These techniques define the validation methodology used for such systems. In order to verify, qualify, and validate knowledge-based systems (KBS's), the methodology used for conventional systems must be addressed, and the applicability and limitations of that methodology to KBS's must be identified. The author presents an outline of how this approach to the validation of KBS's is being developed and used at the Dryden Flight Research Facility of the NASA Ames Research Center

The solution of linear systems of equations with a structural analysis code on the NAS CRAY-2

Two methods for solving linear systems of equations on the NAS Cray-2 are described. One is a direct method; the other is an iterative method. Both methods exploit the architecture of the Cray-2, particularly the vectorization, and are aimed at structural analysis applications. To demonstrate and evaluate the methods, they were installed in a finite element structural analysis code denoted the Computational Structural Mechanics (CSM) Testbed. A description of the techniques used to integrate the two solvers into the Testbed is given. Storage schemes, memory requirements, operation counts, and reformatting procedures are discussed. Finally, results from the new methods are compared with results from the initial Testbed sparse Choleski equation solver for three structural analysis problems. The new direct solvers described achieve the highest computational rates of the methods compared. The new iterative methods are not able to achieve as high computation rates as the vectorized direct solvers but are best for well conditioned problems which require fewer iterations to converge to the solution

Efficient multitasking of Choleski matrix factorization on CRAY supercomputers

A Choleski method is described and used to solve linear systems of equations that arise in large scale structural analysis. The method uses a novel variable-band storage scheme and is structured to exploit fast local memory caches while minimizing data access delays between main memory and vector registers. Several parallel implementations of this method are described for the CRAY-2 and CRAY Y-MP computers demonstrating the use of microtasking and autotasking directives. A portable parallel language, FORCE, is used for comparison with the microtasked and autotasked implementations. Results are presented comparing the matrix factorization times for three representative structural analysis problems from runs made in both dedicated and multi-user modes on both computers. CPU and wall clock timings are given for the parallel implementations and are compared to single processor timings of the same algorithm

Synopsis of biological data on the cobia Rachycentron canadum (Pisces: Rachycentridae)

Information on the biology and fisheries of cobia, Rachycentron canadum, is compiled and reviewed in the FAD species synopsis style. Topics include taxonomy, morphology, distribution, reproduction, pre-adult and adult stages, food, growth, migration, population characteristics, and various aspects of exploitation. Data and information were obtained from unpublished as well as published sources. Cobia, the only species in the family Rachycentridae, is a migratory pelagic fish that occurs in tropical and subtropical seas of the world, except in the central and eastern Pacific Ocean. In the western Atlantic Ocean, spawning occurs during the warm months. Eggs and larvae are planktonic. Females grow faster than males: at 1 year, females are 36 cm FL and 0.4 kg; at 4 years, 99 cm and 11 kg; and at 8 years, 137 cm and 31 kg. Comparable data for males are: at 1 year, 31 cm and 0.3 kg; 4 years, 82 cm and 6 kg; and 8 years, 108 cm and 15 kg. Sexual maturity is attained by males at about 52 cm FL in their second year and by females at about 70 cm in their third year. Fecundity for females 100-125 cm FL varies from 1.9 to 5.4 million eggs. Cobia favor crustaceans for food, but will feed on other invertebrates and fishes as well. They attain a maximum size of over 60 kg. Cobia are fished both commercially and recreationally. Commercially, they are usually caught incidentally in both hook-and-Iine and net fISheries. In the United States, which ranks behind Pakistan, Mexico, and the Philippines in commercial production of cobia, recreational landings exceed commercial landings by more than ten-fold.

The distribution of ctenophora in the Patuxent estuary during the summer of 1958

Investigation of Ctenophores in the Chesapeake Bay area, includes some aspects of their life history, growth, reproduction, feeding and food habits, abundance and distribution. the purpose of the entire project is to supplement and add to the biological knowledge and understanding of ctenophores as a group and of the several individual species found int he area to be studied. Includes possible factors involved and implications also being looked at. (PDF contains 33 pages
