Evaluation of Cutting Performance of Diamond Saw Machine Using Artificial Bee Colony (ABC) Algorithm
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/...
experimental investigation of the surface roughness in grinding of bk7 optical glass in brittle mode
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...
مقدمه : impingement syndrome یکی از بیماریهای شایع است که با درد شانه ومحدودیت حرکت در مفصل شانه همراه می باشد. با توجه به اهمیت این موضوع و لزوم دستیابی به روشی مطمئن جهت درمان مبتلایان به این بیماری، در این مطالعه به بررسی میزان اثربخشی استفاده از glyceril trinitrate بصورت موضعی در درمان مبتلایان بهimpingement syndrome پرداختیم. مواد و روشها: در این مطالعه که از نوع مداخله ای-تحلیلی میباشد60...
