We introduce a class of networks called Isotach networks designed to reduce the cost of synchronization in parallel computations. Isotach networks maintain an invariant that allows each process to control the logical times at which its messages are r

As information may be spread over several distributed and heterogeneous databases (DBs) the expectation for integrated access to them in a comfortable way arises. IRO-DB (Interoperable Relational and Object-Oriented DBs) is a federated database syste

Today there is a wide range of research disciplines that deal with the creation, administration, maintenance and evaluation of knowledge. We focus on two established approaches to knowledge management systems-namely superimposed information as well a

The paper introduces the metadata management concept based on the object oriented paradigm for modeling and querying multidimensional OLAP data. In this model we apply the basic concepts of the object oriented model including object, class, and relat

The casing program of most wells represents a significant portion of the total well cost, approximately between 15 and 35%. Hence, any reduction in tubular cost can generate considerable cost savings. This paper presents a novel and efficient minimum

SPE Members Abstract This paper presents actual surge and swab field data during tripping and circulating operations which include both surface and downhole measurements. These data are compared with a dynamic surge model which includes the effects o

The various aspects of database systems are formalized. An information base is described as a projection of the real world which follows certain semantical constraints. The concepts of the external, conceptual and internal model of a database are int

The reactions 32 S(n, d) 31 P and 34 S(n, d) 33 P have been examined at E n = 14 MeV for E d = 2–8 MeV and θ = 9°–43° with thin, isotopically enriched targets and a two-pulse system of deuteron selection. Total and/or differential cross sectio
