Smart structures and materials

A structure is an assembly that serves an engineering function. It is reasonable to expect that all engineering design should be smart, and not dumb. But one can still make a distinction between smartly designed structures and smart structures. The latter term has acquired a specific technical meaning over the last few decades. A smart structure is that which has the ability to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any changes in its own condition; the response is adaptive in the sense that two or more stimuli or inputs may be received as anticipated and yet there is a single response function as per design. Smartness ensures that the structure gives optimum performance under a variety of environmental conditions. While structures with some degree of smartness have been designed from times immemorial, the current activity and excitement in this field derives its impetus from the level of sophistication achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology, cybernetics, artificial intelligence, and biomimetics.     

Helical angle measurement of worm by a coordinate measuring machine and its uncertainty evaluation

The purpose of the study concerns the measurement of worm’s helical angle by a coordinate measurement machine in the ambient industrial environment. The novel measurement method and sampling strategy were described firstly. This method used the coordinate measurement machine to measure both of the worm gear’s left and right surfaces. The worm surface was reconstructed based on the measured data of all the sampling points. Then a middle cylinder was established to truncate the fitted worm surfaces, and the truncated spiral lines were straightened to calculate the helical angle. The measurement uncertainty of worm’s helical angle was evaluated by taking the difference of calculated helical angles along the truncated spiral lines on both the left and right side surfaces of the worm. Twenty-four measurement experiments show that the maximum measurement error of the proposed method is 0.105, and the measurement error ratios are all less than 3.5?. The result means that the measurement method can realize the precision measurement of worm’s helical angle and can be employed in the generally industrial application.

The effect of adaptivity on the reliability coefficient in adaptive comparative judgement

Comparative Judgement (CJ) is an increasingly widely investigated method in assessment for creating a scale, for example of the quality of essays. One area that has attracted attention in CJ studies is the optimisation of the selection of pairs of objects for judgement. One approach is known as adaptive comparative judgement (ACJ). It has been claimed in the literature that ACJ produces very high reliability, often higher than can be obtained by conventional marking. Bramley showed by simulation that adaptivity can substantially inflate the apparent reliability in ACJ. The empirical study described here compared an adaptive with a non-adaptive CJ study using GCSE English essays. An all-play-all set of comparisons of a subset of the essays allowed the extent of scale inflation to be quantified: the reported adaptive reliability was 0.97 whereas the deflated value was 0.84. The value from the non-adaptive study was 0.72. However, the scale from the non-adaptive study correlated slightly higher with external variables, suggesting the non-adaptive study was no less valid than the adaptive one.

戴震《毛诗补传》中的文献整理方法研究

对戴震《毛诗补传》中文献整理的三种方法——注音、训诂、校勘进行梳理：首先，《毛诗补传》通过注音来表明经文押韵的方法，有直接表明与间接表明两种；它有时又能根据押韵规律来校勘经文。其次，《毛诗补传》训诂特点主要为：注重因声求义、反对缘词生训、点明行文规律。再次，《毛诗补传》校勘内容包括校衍、脱、误、异、错位等，使用校法多样，校法有单独使用与联合使用两种。     

学术期刊论文基金项目的不当标注 ——基于林业行业学术期刊论文基金项目标注的调查统计

在学术期刊评价中,“基金论文比”是一项重要的评价指标,但个别学术论文乱标基金项目的现象一直存在。前人对此方面的研究将原因归于作者或期刊。从发现问题至今15年过去了,但这种现象并未减少。我们认为学术期刊论文基金项目不当标注的深层次原因在于:1)个别科研人员重复申请基金导致论文资助项目标注混乱;2)结题论文“一女多嫁”。以林业行业学术期刊标注基金项目调查结果为例,探讨了当前标注基金项目存在的问题,进而提出建议:1)基金管理部门要规范基金项目的重复申请监测和结项标准;2)学术期刊要正视“基金论文比”存在的真正意义和必要性,在工作中必须要求作者标注基金项目齐全。只有诚信标注基金项目,才能使基金项目真正发挥对科技的支撑作用。
