provenance studies of archaeological ceramics fromMar-Takla (Ain-Minin, Syria) using radioisotope X-rayfluorescence method

引用

Nuclear Science and Techniques 2001年第2期12卷 149-153页

作者： BAKRAjI Elias Hanna, oTHMAN I, KARAjoU j (Atomic Energy Commission, p.o. Box 6091, Damascus, Syria) Atomic Energy Commission of Syria 叙利亚

The radioisotope X-ray fluorescence method was applied to studies of the provenance of the ceramics fragments originated from the Mar-Takla site in Syria. The samples were irradiated 1000s by a 109Cd radioisotope source and 13 elements (Ca, Ti, Mn, Fe, Zn, Ga, As, Rb, Sr, Y, Zr, Nb, and pb) were determined in 35 samples. The data were subjected to two multivariate statistical methods, cluster and principal components analysis (pCA). It was shown from the combination of the statistical techniques and the determination of elemental composition of the samples that 94% of the ceramic samples analyzed can be considered to be manufactured using two sources of raw materials.

Entropy, Fisher Information and Variance with Frost-Musulin potenial

引用

Communications in Theoretical physics 2016年第9期65卷 269-274页

作者： j.o.A.Idiodi C.A.onate physics Department University of Benin

This study presents the Shannon and Renyi information entropy for both position and momentum space and the Fisher information for the position-dependent mass Schr¨odinger equation with the Frost-Musulin potential. The analysis of the quantum mechanical probability has been obtained via the Fisher information. The variance information of this potential is equally computed. This controls both the chemical properties and physical properties of some of the molecular systems. We have observed the behaviour of the Shannon entropy. Renyi entropy, Fisher information and variance with the quantum number n respectively.

Immersion in the Design: Design-for-assembly of Cable Harnesses

厦门大学学报（自然科学版） 2002年第S1期41卷 205-206页

Approaches to efficiency in manufacturing and assem bl y over the past 100 years have concentrated frequently on the twin themes of div iding jobs done by people into defined segments and to automating as many of tho se segments as possible. This approach to manufacturing engineering may be char acterised as one of deconstruction and replacement so far as the role of the hum an being is concerned. More recently design engineering has been approached in a similar light with research into ’intelligent’ methods involving, for example, expert systems or genetic algorithms to handle an increasing proportion of desi gn tasks. Expert systems are predicated on the idea that it is possible to capture and systemise significant amounts of professional knowledge: a task that has proved with experience to be much more difficult than when such systems wer e first proposed. Genetic algorithms, notwithstanding considerable research eff ort, have yet to make significant inroads into the practise of design and manufa cture. This paper will draw on new and previous experimental work carried out with supp ort from industry to propose an alternative approach that is enabled by the prod ucts of modern information technology. In this paradigm it is recognised that t he involvement of the human design expert is, for the time being at least, inevi table. Rather than seeking to reduce or even eliminate the " expert" with his or her tacit knowledge, the aim is to provide the expert with interactive to ols including immersive virtual reality so that implicit, human expertise can be applied effectively in the design cycle. The proposed approach is considered in the context of a particularly costly and difficult task, namely the design and planning for manufacture and assembly of c able harnesses for use in electro-mechanical artefacts. The efficient and reli able manufacture of cabling systems for many such products in the aerospace, aut omotive and IT sectors provides diverse challenges to des
