We describe a tool that improves the process of verifying relations between descriptions of a distributed algorithm at different levels of abstraction using interactive proof assistants. The tool automatically translates algorithms, written in the IOA language, into first-order logic, expressed in the Larch Shared Language, in a style that facilitates reasoning with a theorem prover. The transl...

The face is one of the most important stimuli carrying social meaning. Thanks to the fast analysis of faces, we are able to judge physical attractiveness and features of their owners' personality, intentions, and mood. From one's facial expression we can gain information about danger present in the environment. It is obvious that the ability to process efficiently one's face is crucial for surv...

Abstract Little is known about sex and gender differences in the daily life activities of early medieval Avar populations. Of particular interest habitual horse‐riding, which assumed to be typical for these Importantly, fundamental changes “Avar lifestyle” occurred over time this may have led less horse‐riding. This study identifies possible chronological prevalence metric nonmetric traits indi...

We show how to use a decision procedure for WS1S (the MONA tool) to give automated correctness proofs of a sliding window protocol under assumptions of unbounded window sizes, buffer sizes, and channel capacities. We also verify a version of the protocol where the window size is fixed. Since our mechanized target logic is WS1S, not the finite structures of traditional model checking, our method...

Air pollution sources and the hazards of high particulate matter 2.5 (PM2.5) concentrations among air pollutants have been well documented. Shipping emissions identified as a source pollution; therefore, it is necessary to predict pollutant manage seaport quality. However, prediction models rarely consider shipping emissions. Here, PM2.5 Busan North New Ports were predicted using recurrent neur...

Since more than twenty years, Internet evolves as well as users’ needs. and the users’ needs too. The need of bandwidth growths every day with the new usages. In this context, with megabit per second count. There is a real business behind our free access to web site. From a group of island, the economy of bandwidth can be a major challenge. Installing a Regional Internet eXchange Point (RIXP) c...

Nowadays email has become the most widely used means in daily communication on the net and is increasingly used in place of ordinary mail. Certified email protocols aim to provide additional properties to the standard email service. In this paper we provide a novel optimistic protocol for certified email satisfying nine of the most important properties usually considered in the literature. We g...

Atlantic Salmon (Salmo salad redds were exanuned in t.he upperSusqueherma River during November of 1992 and 1993 at Cooperstown, W{, In 1993, ten redds were composed of 10% boulder, 12% cobble, 52% pebble, 18% gravel and 8% sand. Five redds in 1992 had a composition of 42% cobble, 36% gravel and 10% sand. Fish were sampled with a fine rnesh drift net to provide ages, lengths, weights and sex. A...

The 2dF Galaxy Redshift Survey is the first to observe more than 100,000 redshifts. This allows precise measurements of many of the key statistics of galaxy clustering, in particular redshift-space distortions and the large-scale power spectrum. This paper presents the current 2dFGRS results in these areas. Redshift-space distortions are detected with a high degree of significance, confirming t...
