Global analyzers traditionally read and analyze the entire program at once, in a non-incremental way. However, there are many situations which are not well suited to this simple model and which instead require reanalysis of parts of a program which has already been analyzed. In these cases, it appears ineecient to perform the analysis of the program again from scratch, as needs to be done with ...

interpretation is a technique for ow analysis widely used in the area of logic programming. Until now it has been used only for the global compilation of Prolog programs. But the programming language Prolog enables the programmer to change the program during run time using the built-in predicates assert and retract. To support the generation of eecient code for programs using these dynamic data...

723 well prepared to fight new communicable diseases. Biologists will be key collaborators in this battle but they need to be guided by good epidemiological data. Methodology is the glue that binds epidemiologists together whether we work in public health epidemiology, clinical epidemiology or genetic epidemiology. There is no contradiction between taking an interest in global public health and...

As the size of a formal model increases, state space analysis becomes more complex in terms of time or space or both. This complexity means that state space analysis of a formal model is often practically impossible, even for a modest sized system. Recently techniques to reduce the complexity have done so by taking advantage of the structure built into the model by the designer (e.g. [16]). In ...

We present the first fully general approach to the problem of incremental lexical analysis. Our approach utilizes existing generators of (batch) lexical analyzers to derive the information needed by an incremental run-time system. No changes to the generator’s algorithms or run-time mechanism are required. The entire pattern language of the original tool is supported, including such features as...

distribution of label in the IEA patterns of the SON fractions was not affected by the addition of serum carrier, it seems unlikely that nonspecific binding of radioactive material to serum proteins occurs to any appreciable extent. There is the possibility that highly radioactive material in the SON fraction migrating with the same electrophoretic mobility is trapped and concentrated in the im...

One of the aims of the IEA Greenhouse Gas R&D Programme (IEA GHG) is to understand how to facilitate the introduction of technologies capable of making deep reductions in CO2 emissions, for example capture and geological storage of CO2. This technology faces a number of barriers to its introduction, such as the high cost of capture of CO2 from power plant. This high cost arises from the amount ...

The Slow Feature Analysis (SFA) unsupervised learning framework extracts features representing the underlying causes of the changes within a temporally coherent high-dimensional raw sensory input signal. We develop the first online version of SFA, via a combination of incremental Principal Components Analysis and Minor Components Analysis. Unlike standard batch-based SFA, online SFA adapts alon...

Semantic analysis is a central part of the compilation process. The main subproblems include name analysis, type checking, and detection of static-semantic errors. In an interactive programming environment it is useful to perform the semantic analysis incrementally, keeping the staticsemantic information up to date while the program is edited. This allows advanced browsing and editing facilitie...
