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...

Recent work has shown a convergence between the Human Factors and Formal Methods communities that opens promising new directions for collaborative work in calculating, predicting, and analyzing the behavior of complex aeronautical systems and their operators. Previously it has been shown that fully automatic, finitestate verification techniques can be used to identify likely sources of mode con...

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...

environmental optimizing of pest management strategies and improving theirs trends towards minimum environmental risks programs is a matter of considerable concern of food scientists particularly in developing countries. this study evaluates the environmental impacts of pesticides consumption based on environmental impact quotient (eiq) model in different sugar beet (beta vulgaris l.) productio...
