.... and concept is necessary in order to understand term variation and ambiguity, both of which are crucial to the theoretical study of terminology and its practical applications [20] Ideally, terms should be monoreferential, i.e. there should be a one to one correspondence between term and concept [17]. In practice, however, this is not the case, and terms may exhibit both polysemy and synonymy. It is now generally acknowledged that monoreferentiality of terms is no longer practical or even necessarily 3 desirable [32, 4] The problem of term ambiguity is therefore strongly correlated with the ....

Only sub classes for which a de nition has been provided for each pure virtual method can be instantiated. An alternative approach is taken in Ada 95 [38], where the programmer declares the type of an object to be class wide , using the Class annotation, if dynamic dispatch is to be used for that object. This associates dynamic dispatch with particular references to objects rather than with particular methods or classes. In the following example ....

We can say that the environment of a TwoQs process is its client. Now let us consider a liveness property which we would reasonably require such a system to ful l.

These criteria determine the general evaluation frameworks for the investigation of man machine systems. In addition, further specification demands are considered, as specified, e.g. in ISO 9241 part 10 [3]. With consideration of the above mentioned criteria an environment is developed, which enables the developer to evaluate a technical system promptly regarding to ergonomic requirements.

....code (like C, C or Java) can be used as a CGI application. Prolog, being a high level symbolic language, is an excellent tool for programming WWW applications [1, 2, 11] but some implementations do not allow the creation of executable code. Furthermore, in the standard Prolog definition [9] there is no way to refer directly to environment variables. That is why, if we want to use Prolog as a programming language for WWW applications, we have to provide an executable program (i.e. a binary or script file) that can invoke the Prolog interpreter, load a given program and run it. For ....

....meanings. We have used the framework defined in [39, 40] and represented the meaning of system predicates in terms of edges and nodes in the graph. This framework can be customised to any language. For the sake of brevity, in this paper we have employed only a subset of Prolog system predicates [9, 21, 35] consisting of = 2, is 2, 2 and 2. 9 5.1 Detecting Potential Changes via Modes In order to build the term dependence graph we need to know which computations may have taken place in each literal.

....of the original subgoal) We now turn our attention to system predicate is 2, employed to perform arithmetics. This predicate works by evaluating the contents (an arithmetic expression) of the variable on its right hand side and unifying the result with the variable on its left hand side [9, 35, 21]. The following formula addresses is 2 subgoals: TGraph G ( hc; l; x is yi 0 ; fx ( yg) changes(x; 0 ) 5) That is, data has flowed from y to x. Contrary to = 2, the reverse situation need not be represented: predicate is 2 does not allow values to be passed on to its right hand ....

....The work in this thesis has a foot in both these areas, which share common ground. We develop an object oriented semantics (based upon a constructive, easy to understand, state transition system model) The abstract data type (ADT) part of LOTOS (Language Of Temporal Ordering Specifications) see [15, 112, 113, 68, 117], is used to implement the requirements models which are defined using this semantics. Then, full LOTOS (LOTOS with the ADT and process algebra parts) is used to model the requirements in a more concrete framework. In the thesis, LOTOS specifications are constructed using object oriented ....

Software process assessment is based on the ISO 15504 for software process assessment 1 [3].

Consequently, it can be used at both ends of the software development spectrum. Its natural division into ADT part (based on ACT ONE [21] and process algebra part (similar to CSP [27] and CCS ....

What are the basic components of communications services and protocols The OSI Basic Reference Model ([2]) defines some static components (e.g. service access point, layer, and title) and some dynamic components (e.g. multiplexing, segmentation, and flow control) However, these concepts are informally (and sometimes fuzzily) defined, and are still quite high level. Some recent work [15] has focussed ....

Elementary interactions between a user and the provider are termed service primitives which are taken as the building blocks for service definitions [ISO92]. Service primitives occur at abstract interfaces called SAPs (service access points) each of which is distinguished by means of a unique address.
