面粉厂车间楼定向倾倒爆破

该楼体为框架结构,是车间楼和办公楼的结合体,由于加工面粉设备流程的需要,该楼同时承受动荷载和静荷载。楼体按照伸缩缝分为3部分,每部分的结构不相同,同部分不同层结构也各异。在爆破过程中严格控制各种参数,并采取有效的减振与防护措施,使此爆破工程在安全和质量上都达到了预期效果。     

Gluten-free cakes with walnut flour: a technological,sensory, and microstructural approach

Walnut flour (WF), a by-product of walnut oil production, is characterised by high polyunsaturated fatty acids, proteins, and fibre contents and presents suitability for bakery products. However, when using non-traditional ingredients, it is essential to evaluate the effect on the quality properties of the final product. So, this work aimed to assess the impact of WF on the technological, physicochemical, and sensory properties of gluten-free (GF) cakes. WF was added at a flour blend (cassava (CS) and maize (MS) starches and rice flour) at 0, 10%, 15%, and 20%. The results showed that WF modified starch gelatinisation, increased amylose–lipid complex (ALC) content, and made crumbs easier to chew. Besides, the total dietary fibre (TDF) and protein content significantly increased. Cakes with 15% WF presented the highest specific volume (SV) and no differences in overall acceptability with respect to control. Hence, WF is a suitable ingredient for gluten-free bakery products.     

Green Measurements for Software Product Based on Sustainability Dimensions

Software is a central component in the modern world and vastly affects the environment’s sustainability. The demand for energy and resource requirements is rising when producing hardware and software units. Literature study reveals that many studies focused on green hardware; however, limited efforts were made in the greenness of software products. Green software products are necessary to solve the issues and problems related to the long-term use of software, especially from a sustainability perspective. Without a proper mechanism for measuring the greenness of a particular software product executed in a specific environment, the mentioned benefits will not be attained. Currently, there are not enough works to address this problem, and the green status of software products is uncertain and unsure. This paper aims to identify the green measurements based on sustainable dimensions in a software product. The second objective is to reveal the relationships between the elements and measurements through empirical study. The study is conducted in two phases. The first phase is the theoretical phase, where the main components, measurements and practices that influence the sustainability of a software product are identified. The second phase is the empirical study that involved 103 respondents in Malaysia investigating current practices of green software in the industrial environment and further identifying the main sustainability dimensions and measurements and their impact on achieving green software products. This study has revealed seven green measurements of software product: Productivity, Usability, Cost Reduction, Employee Support, Energy Efficiency, Resource Efficiency and Tool Support. The relationships are statistically significant, with a significance level of less than 0.01 (p = 0.000). Thus, the hypothesised relationships were all accepted. The contributions of this study revolve around the research perspectives of the measurements to attain a green software product.

食用槟榔货架期内品质控制研究

目的：探究食用槟榔返卤返白的原因。方法：主要通过搜集2000—2020年涉及食用槟榔卤水专利，以及相关工厂案例进行研究与分析。结果：在食用槟榔卤水的制备过程中原料的粒径大小、环境温度与湿度的高低、样品中水分含量及设备的自动化程度均可能造成食用槟榔返卤返白。结论：加工槟榔时应采取以严格控制水分、复配添加剂使用为主，工艺包装调整为辅,给予低温贮藏市售环境的方法，抑制返卤返白的产生。     

基于宇宙量子算法的微小零件尺寸检测

通过建立主、从式宇宙空间结构改善了量子算法的运行效率,非正交二次B样条小波和最小二乘小波支持向量回归机对零件边缘进行检测,给出了微小零件尺寸检测流程。试验仿真显示该算法对微小零件尺寸测量数据波动范围较小,方差值相比其他方法值较低,其中UQ算法测量的外轮直径测量方差值比HI、MM、AIT、IF、IGR算法分别减少了75.29%,78.40%,64.47%,60.95%,52.15%;UQ算法测量的内轮直径测量方差值比HI、MM、AIT、IF、IGR算法分别减少了72.89%,76.75%,62.66%,59.22%,50.13%,提高了微小零件的精度测量。     

单自由度八杆仿生机构构型与尺度同步设计方法

单自由度八杆仿生机构杆长参数较多，是仿生机器人领域研究的难点之一。为提高设计效率，提出一种构型与尺度同步设计方法。在选定的运动链和机架的基础上，以不等式形式分步给出运动可行性及外形约束条件，使得上一步的杆长可作为下一步求解的已知值。通过该过程，在得到八杆仿生机构构型的同时，快速得到所有杆长的初步可行域。循环上述过程，逐步缩小约束条件的范围，可使得八杆机构的杆长快速接近目标值。在此基础上，分类讨论了连杆搭接顺序、约束条件及基本运动链的差异对求解难度及构型结果的影响。利用所提出的单自由度八杆仿生机构的设计方法，在对初始条件进行合理选取的前提下，可在初步得到构型的同时将杆长限定在较小范围内，实现了构型与尺度的同步设计。该方法还可应用于其他单自由度机构的设计当中，具有较好的借鉴意义。     

一种军棋机器博弈的多棋子协同博弈方法

针对在军棋博弈不完全信息对弈中，面对棋子不同价值、不同位置、不同搭配所产生的不同棋力，传统的单子意图搜索算法，不能满足棋子之间的协同性与沟通性，同时也缺乏对敌方的引诱与欺骗等高级对抗能力。本文提出一种结合UCT搜索策略的高价值棋子博弈方法，实现高价值棋子协同博弈的策略。实战经验表明:高价值多棋子军棋协同博弈策略优于单棋子军棋博弈策略。
