On Being Conservative

رابطه وجود و ماهیت در رساله ‏‎"on being and essence"‎‏

هدف عمده ای که من در رساله خود تعقیب می کنم بررسی رابطه وجود و ماهیت از نظر توماس آکوئینی در رساله معروف خود تحت همین نام، است، که نام لاتین آن ‏‎de ente et essentia‎‏ می باشد و ترجمه انگلیسی آن تحت عنوان ‏‎"on being and essence"‎‏ است که ترجمه معمول آن به فارسی ((وجود و ماهیت)) می باشد. البته بهترین ترجمه فارسی واژه ‏‎ente‎‏، ((موجودیت)) است ولی ما مطابق رسم آنرا رساله ((درباره وجود و ماهیت)) ...

Timing the Untimed: Terminating Successfully While Being Conservative

There have been several timed extensions of ACP-style process algebras with successful termination. None of them, to our knowledge, are equationally conservative (ground-)extensions of ACP with successful termination. Here, we point out some design decisions which were the possible causes of this misfortune and by taking different decisions, we propose a spectrum of timed process algebras order...

The Role of Informative Priors in Zero-Numerator Problems: Being Conservative Versus Being Candid

The “Rule of Three” gives an approximation for an upper 95% conŽ dence bound for a proportion in a zero-numerator problem, which occurs when the observed relative frequency is zero. We compare the results from the Rule of Three with those from a Bayesian approach with noninformative and informative priors. Informative priors are especiallyvaluable in zero-numerator problems because they can rep...

On Exactly Conservative Integrators

Traditional explicit numerical discretizations of conservative systems generically predict arti cial secular drifts of nonlinear invariants. These algorithms are based on polynomial functions of the time step. We discuss a general approach for developing explicit algorithms that conserve such invariants exactly. We illustrate the method by applying it to the truncated two-dimensional Euler equa...
