We describe the mechanization of recent examples of compositional reasoning, due to Charpentier and Chandy [4]. The examples illustrate a new theory for composition proposed by Chandy and Sanders [2, 3], based on the so-called existential and universal properties. We show that, while avoiding hand proof mistakes, a such compositional reasoning can be mechanized quite straightforwardly. We also ...

Civil-military relations are characterized by a fundamental dilemma. To lower coup risk, leaders frequently empower the military, which satisfies armed forces with status quo and enables them to fight against threats challenging civilian leadership. Simultaneously, too powerful military itself constitutes potential threat that is capable of overthrowing government. Our research adds this debate...

A mean mechanization index of 0.59 and a total machinery energy of 477.78 MJ/ha were recorded for the direct seeding paddy cultivation in Malaysia. Highest mechanization index and machinery energy were obtained in the harvesting operation (0.99 and 336.81 MJ/ha) while the lowest values were in pesticides operations (0.19 and 3.97 MJ/ha). The benefit-cost ratios for an average farmer with and wi...

The most powerful tools for analysis of formal speci cations are general-purpose theorem provers and model checkers, but these tools provide scant methodological support. Conversely, those approaches that do provide a well-developed method generally have less powerful automation. It is natural, therefore, to try to combine the better-developed methods with the more powerful general-purpose tool...
