Review of Language in the Americas.

Reviews the book, Language in the Americas by Joseph H. Greenberg (1987). Greenberg's work on universals of language has crossed disciplinary boundaries to become known to many psychologists interested in language. His equally important work in language classification, of which Language in the Americas is one part, remains unfamiliar to psychologists. This book is a pioneering work in that it is the first genetic classification of the indigenous languages of both North and South America. Greenberg maintains that all of the languages of the Americas belong to three families: Eskimo-Aleut, Na-Dene, and a family that he has named Amerind. This assertion is both important and controversial; the controversy lies in the grouping of most of the languages including all of those of South and Central America into the Amerind family. Most of Language in the Americas consists of the Amerind etymological dictionary, arranged so that the reader can assess lexical similarities within and between subgroups. Greenberg's discussion is informed, articulate, profound, and to the point. He draws on relevant sources and examples from diverse fields of knowledge. The depth and breadth of his scholarship and the clarity of his presentation create a work that is an intellectual pleasure to read. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

一种可任意扩展的多路级联采集电路设计

在长距离需要对多路数据进行采集的情况下,提出了一种基于FPGA的多路级联式采集系统。本系统以FPGA为核心,实现对各路采集单元的命令控制和数据传输控制,并且各采集单元相互独立、所采集的数据单独存储。实验测试结果表明,各路采集数据能够可靠传输到读数单元。各采集单元以级联方式连接,可在采集点自由增减采集单元,实现任意路数据的采集与存储。     

A string pattern matching extension to pascal and some comparisons with snobol4

This paper presents an extension of Pascal with string pattern matching. Pattern definitions are built using six basic operations: alternation, concatenation, immediate value assignment, intersection, difference and complement. The last three have not been previously implemented and they increase the expressive power beyond context-free languages. The pattern matching actions are augmented with three options: trace, prefix and suffix. Comparisons with a SNOBOL4 implementation are also presented. This experiment demonstrates that Pascal with pattern matching is a useful tool for string processing applications.     

A pattern language for designing e-business architecture

The pattern language for e-business provides a holistic support for developing software architectures for the e-business domain. The pattern language contains four related pattern categories: Business Patterns, Integration Patterns, Application Patterns, and Runtime Patterns. These pattern categories organise an e-business architecture into three layers—business interaction, application infrastructure and middleware infrastructure—and provide reusable design solutions to these layers in a top-down decomposition fashion. Business and Integration Patterns partition the business interaction layer into a set of subsystems; Application Patterns provide a high-level application infrastructure for these subsystems and separate business abstractions from their software solutions; Runtime Patterns then define a middleware infrastructure for the subsystems and shield design solutions from their implementations. The paper describes, demonstrates and evaluates this pattern language.     

Murg term rewrite systems

The union of a monadic and a right-ground term rewrite system is called a murg term rewrite system. We show that for murg TRSs the ground common ancestor problem is undecidable. We show that for a murg term rewrite system it is undecidable whether the set of descendants of a ground tree is a recognizable tree language. We show that it is undecidable whether a murg term rewrite system over Σ preserves Σ-recognizability.
