  • This essential survival guide for successfully managing the modern-day IVF clinic condenses a wealth of expertise and experience from the authors in trou-bleshooting and implementing quality management in the IVF laboratory. With high-profile media coverage of mistakes at IVF clinics and escalating regula-tory scrutiny, there is increasing pressure for professional accreditation. Modern accreditation schemes, which are largely based on the principles of ISO 9001 and related standards, require quality systems.

  • Validation of Communications Systems with SDL provides a clear practical guide to validating, by simulation, a telecom system modelled in SDL. SDL, the Specification and Description Language standardised by the International Telecommunication Union (ITU-T), is used to specify and develop complex systems such as GSM, GPRS, UMTS, IEEE 802.11 or Hiperlan. Since the downturn in the telecom industry, validating a system before its implementation has become mandatory to reduce costs.

  • Default inheritance is a useful tool for encoding linguistic generalisations that have exceptions. In this paper we show how the use of an order independent typed default unification operation can provide non-redundant highly structured and concise representation to specify a network of lexical types, that encodes linguistic information about verbal subcategorisation.

  • Our poster presents results and experiences from the application of the system to 300,000 word forms, a subpart of a larger corpus. The application of the system is carried out in two steps, an automatic lexical look up followed by homograph separation, which is done partly automatically, partly manually. Lexical and morphological analysis and disambiguation of Swedish is a rather complicated task, a fact which should hold for several other languages as well. Below a sample text is given, showing both the amount of information that has to be specified for each word form and the degree of...

  • To develop a syntactic and semantic analysis using this framework, a network of the words for a given sentence is constructed. Each word is given some number indicating its position relative to the other words in the sentence. Once a word is entered in the network, the system assigns all of the possible roles the words can have by applying the lexical constraints (which specify legal word categories) and allowing the word to modify all the remaining words in the sentence or no words at all. Each of the arcs in the network has associated with it a matrix...

  • Lip until now, no automated system for these insertion tasks existed. INSYST (INserter SYSTem), we describe here, can efficiently insert lexical items under the appropriate nodes in hierarchies. It currently handles hierarchies specified in the DATR formalism (Evans and Gazdar 1989, 1990). The system uses a classification algorithm that maximizes the number of inherited features for each entry.

  • This chapter discusses a programmer’s view of files and the file system. It describes fundamental file organizations, directory structures, operations on files and directories, and file sharing semantics, which specify the manner in which results of file manipulations performed by concurrent processes are visible to one another. Issues that compromise reliability of a file system are discussed. Fault tolerance using atomic actions and recovery using backups are described.
