Reframing Pinterest: Information Literacy for Interior Design Students

This article discusses providing information literacy to interior design students, specifically how over a few years, and several assignment iterations, we moved from a more traditional one-shot library instruction session to a creative Association of College and Research Libraries Framework-inspired assignment using Pinterest as the medium for the students' professionally relevant research project. The outcome of our instruction relied on flexible assignment planning, collaboration as faculty and librarians changed roles, and a focus on information literacy skills needed by professional designers.

Another look at the phenomenon of phase transition

This study is motivated by the question whether there exists a characteristic feature common to the phenomenon of phase transition of properties taking place in the course of evolution of various sets of objects of different nature. A novel measure model of phase transition is presented, providing an insight into the process underlying different phase transitions. First, it is shown to conform to several famous and extensively investigated cases of phase transition. Then a few close consequences of applying the measure model are presented. It has been proved that monotone properties undergo a sharp phase transition. The measure model provides a sufficient condition of a sharp phase transition common to monotone and non-monotone properties as well. The measure model reveals that if a property Q undergoes a phase transition in the course of evolution of objects of a certain type, then there exist other secondary properties related to the measure of Q that also undergo a phase transition during the evolution.     

Integrated optimisation on flow-shop production with cutting stock

This paper addresses the integrated scheduling optimisation on flow-shop production with one-dimensional cutting stock in make-to-order environments. The upstream cutting-stock process provides the items for the downstream production, while the flow-shop production can be executed only when the required items are released. The efficient schedules on cutting plan and the production sequence should be determined in a coordinated manner to improve the overall efficiency. This study aims to find an integrated schedule to minimise the makespan of the entire manufacturing process. We develop a hybrid algorithm by integrating a local search method and some efficient strategies under the nested partitions framework. Numerical experiments show that the proposed approach is capable of achieving high-quality solutions within a reasonable time.

外撑内拉支撑体系在Y型墩施工中的应用研究

在水流湍急、地质较差的条件下进行桥梁工程施工时,为缩短Y型墩施工工期、尽量减少对环境的破坏,需对传统支撑体系进行改进与创新。提出了一套劲性骨架与外撑内拉支撑体系相结合的施工方法,并结合其工艺原理及施工过程采用有限元方法对其进行了数值模拟验证,得到了拉杆张拉力及伸长量与施工阶段的对应关系,同时对Y型墩施工过程中的线形与裂缝控制关键技术进行了总结。工程实践表明,该支撑体系具有施工操作简单、施工速度快、整体结构刚度大、适用性强等特点,可为今后类似工程施工提供借鉴。     

基于变量代换内点法的加权最小绝对值抗差状态估计

传统内点法加权最小绝对值(WLAV)抗差状态估计能够抑制坏数据影响,提高状态估计精度,但该方法模型复杂,计算效率低,限制了其工程应用价值。文中提出一种基于变量代换内点法的电力系统WLAV估计方法,该方法通过添加中间变量,将非线性量测方程分解为两步线性方程和两步非线性变换,并建立两步线性方程的WLAV估计数学模型。与传统内点法WLAV抗差状态估计相比,该方法无须形成海森矩阵,可有效提高迭代方程中系数矩阵的稀疏度,并减小矩阵的阶数,有效提高WLAV状态估计的计算速度。基于美国电气与电子工程师学会(IEEE)标准系统、波兰电网和国内某省网的仿真结果验证了所述方法的有效性,具有良好的工程应用前景。
