Abstract We present hypersequent calculi for the strongest logics in Lewis’ family of conditional systems, characterized by uniformity and total reflexivity. first a non-standard calculus, which allows syntactic proof cut elimination. then introduce standard calculi, sequents are enriched additional structures to encode plausibility formulas diamond formulas. Proof search using these is termina...

Artificial Intelligence (AI) techniques are used for solving the intractable engineering problems. In this study, it is aimed to study the application of artificial bee colony algorithm for predicting the performance of circular diamond saw in sawing of hard rocks. For this purpose, varieties of fourteen types of hard rocks were cut in laboratory using a cutting rig at 5 mm depth of cut, 40 cm/...

surface roughness is a significant parameter which determines the efficiency of optical components. surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. it is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. in this study, a cup diamond wheel (d64) is used in grinding pr...

We report the systematic studies on the fabrication of aligned, uniform, and highly dense diamond nanostructures from diamond films of various granular structures. Self-assembled Au nanodots are used as a mask in the self-biased reactive-ion etching (RIE) process, using an O2/CF4 process plasma. The morphology of diamond nanostructures is a close function of the initial phase composition of dia...

not all values of literary texts should be sought for in their artistic aspects . there have been many lower-ranked literary texts that have shed light on numerous scientific, historical, social, and cultural issues. although poetic views are involved while raising such issues, it needs to be taken into account that not all poets have perceived the scientific principles of the topics tackled in...

like other valuable consideration marriage contracts are permissible provided the acceptability of any particular problem, but the marriage contracts, and have initiated some work on it should be welcoming as it is. including conditions in the marriage if there is no sex.some respected researchers in the licensing documents such condition as not warrant deference to be, were considered. to prov...

The Ultra-nanocrystalline diamond (UNCD) was synthesized by the detonation of a high explosive mixture in water confinement. The presence of a diamond phase was revealed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). X-ray line broadening (XRLB) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. The micro st...

We report the discovery of vertically aligned nano-scale diamond tips grown on the polycrystalline diamond substrates in a CH4/N2/H2 mixed plasma. The best diamond quality occurs at the top part of the nanotip, which is single crystalline diamond. The quality of the diamond nanotip is justified by the diamond characteristic peak at 1332 cm 1 in the Raman spectrum, the discrete electron diffract...

we prove that the limit of a sequence of pettis integrable bounded scalarly measurable weak random elements, of finite weak norm, with values in the dual of a non-separable banach space is pettis integrable. then we provide basic properties for the pettis conditional expectation, and prove that it is continuous. calculus of pettis conditional expectations in general is very different from the c...

researchers of language teaching believe that teaching method has a lot of impact on the speed and depth of learning. the importance of this is so obvious on teaching some persian language structures which are syntactically and semantically complicated. one of these structures is conditional sentences which has been considered in this study. here we tried to teach conditional sentences via both...
