The formal verification of compilers and related programming tools depends crucially on the availability of appropriate mechanized semantics for the source, intermediate and target languages. In this invited talk, I review various forms of operational semantics and their mechanization, based on my experience with the formal verification of the CompCert C compiler. What does this program do, exa...

The following outline summarizes some suggestions about ways in which translation may be mechanized that were worked out by the authors in 19481952. The treatment is not exhaustive, and many modifications in detail would certainly be necessary should the ideas here mooted be put into active operation. It is considered, however, that it would be serviceable to describe the techniques here envisa...

Formal, modular, and mechanized verification of realistic systems code is desirable but challenging. Verification of machine context management (a basis of multi-tasking) is one representative example. With context operations occurring hundreds to thousands of times per second on every computer, their correctness deserves careful examination. Given the small and stable code bases, it is a commo...

Currant is a technological, fast-growing, high-yielding crop with high content of vitamins in the fruit. The intensification production provides for an increase productivity plantings and reduction cost due to introduction new cultivation technologies. main expenses are connected harvest. authors this paper present first modern berry harvesters that reduce ensure automated labor. prospect using...

ion in AI and CS In the early days of CS, algorithms were often seen as an abstract formulation of procedures. Nowadays, this workshop illustrates well that category theory is associated to an abstract formulation of CS. The example of computer algebra teaches us that such methodologies do not amount to a full abstraction paradigm. Giunchiglia and Walsh introduced theories of abstraction for me...

The successful establishment of agricultural crops depends on sowing quality, machinery performance, soil type and conditions, among other factors. This study evaluates the operational quality of mechanized peanut sowing in three soil types (sand, silt, and clay) with variable moisture contents. The experiment was conducted in three locations in the state of São Paulo, Brazil. The track-samplin...

A major barrier to more common use of mechanical theorem provers in verifying software designs is the signi cant distance between proof styles natural to humans and proof styles supported by mechanical provers. To make mechanical provers useful to software designers with some mathematical sophistication but without expertise in mechanical provers, the distance between hand proofs and their mech...
