A Tutorial on Algol 68

A One Pass Algorithm for Compiling ALGOL 68 Declarations

A Space-Saving Technique for Assigning Algol 68 Multiple Values

The undghtforward way of elaborating an assignation d :its in an ALGOL 68 implementation is (1): • elaborate the destination d and the source s, yielding a name N and a value V; • assign fire value V to the Elaine N. In many cases, the elaboration of s will consist of the ovation of a copy on the working stack of an already existing value V. This value is assigned to N by copying it once more i...

On the Transformational Derivation of an Efficient Recognizer for Algol 68

During the sixties two level van Wijngaarden grammars (2vwg) were introduced for the formal definition of Algol 68. Two level van Wijngaarden grammars provide a formalism suited for writing rigorous formal definitions which read like human prose. Both the context free and context sensitive syntax of Algol 68 are defined in 2vwg. However, the specification is not executable. The Extended Affix G...

A tutorial on Quasi-experimental designs

A main step in answering a scientific hypothesis in an epidemiological study is deciding which type of study is suitable to be undertaken, considering methodology, practical considerations and budget and time limitations

Medical nanobiosensors: A tutorial review

A sensitive monitoring of biological analytes, such as biomolecules (protein, lipid, DNA and RNA), and biological cells (blood cell, virus and bacteria), is essential to assess and avoid risks for human health. Nanobiosensors, analytical devices that combine a biologically sensitive element with a nanostructured transducer, are being widely used for molecular detection of biomarkers associated ...
