Abstract Common meadows are arithmetic structures with inverse or division, made total on $0$ by a flag $\bot $ for ease of calculation. We examine some axiomatizations common to clarify their relationship commutative rings and serve different theoretical agendas. A meadow fracterm calculus is special form the equational axiomatization meadows, originally based use division rational numbers. st...

PART I of this special issue on signal processing for wireless communications, published in October 1998, contained 21 papers on diversity and antenna arrays, blind techniques, and orthogonal frequency division multiplexing (OFDM)-related techniques. In this issue, we present 22 papers on equalization and signal detection and multiuser detection and code division multiple access (CDMA)-related ...

In an abstract model of division problems, we study division rules that are not manipulable through a reallocation of individual characteristic vectors within a coalition (e.g. reallocation of claims in bankruptcy problems). A coalition can be formed under a given communication network, a (non-directed) graph, if members of this coalition are connected on the graph. We offer a characterization ...

Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction-the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of in...

In addition to this aim, the study served another purpose of particular value to the Division of Special Education, in that it afforded a sample of the performance of normal sixth grade children. Every year there are referred to the psychological clinic of this division, thousands of children who are doing unsatisfactory work in the grades. It is of value to know how the performance of these ch...
