Differential scanning calorimetry (DSC) is one of the few techniques that allow direct determination of enthalpy values for binding reactions and conformational transitions in biomolecules. It provides the thermodynamics information of the biomolecules which consists of Gibbs free energy, enthalpy and entropy in a straightforward manner that enables deep understanding of the structure function relationship in biomolecules such as the folding/unfolding of protein and DNA, and ligand bindings. This review provides an up to date overview of the applications of DSC in biomolecular study such as the bovine serum albumin denaturation study, the relationship between the melting point of lysozyme and the scanning rate. We also introduce the recent advances of the development of micro-electro-mechanic-system (MEMS) based DSCs.

在大型飞机装配过程中,三维轮廓扫描对于装配质量检测具有关键作用。为实现大型飞机零部件高反光曲面轮廓的扫描测量,本文提出一种兼顾精度与效率的非接触式自动化测量系统和方法。首先,以距离传感器辅助摄影测量,建立一种非接触式三维坐标复合测量系统,避免被测表面高反光对摄影测量精度的影响。同时,建立一种蕴含距离传感器一维测距信息与视觉全局转换关系的复合式坐标测量模型,高精度解算被测量点的三维坐标。其次,构建一种轮廓信息驱动的形面自动扫描方法和策略,在距离传感器有效量程内实现形面的非接触快速扫描与轮廓重建。最后,在某型号飞机平尾升降舵(尺寸约1760 mm × 460 mm)装配过程中对所提系统及方法进行现场试验与精度分析。实验表明:整个测量过程用时仅208 s,形面轮廓重建精度优于0.121 mm,因此,鉴于大型飞机装配过程中形面轮廓的高精度和高效率测量要求,所提系统及方法具有广阔应用前景。

现代微电网的重要特征是其核心的分布式能源和控制系统普遍依赖网络通信和软件系统。信息与物理系统的集成使得微电网获得了极佳的分布可控性、可扩展性和可观性;然而,恶意网络攻击者由此亦可以利用微电网信息物理系统中各种潜在的漏洞对微电网实施破坏。本文提出一种可编程自适应安全扫描(PASS)技术,用以保护电力电子化微电网系统免受各类电力机器人(power bot)的攻击。这一新技术尤其可以有效抵御三种危害性较大的攻击,即控制器操纵攻击、重放攻击和注入攻击。可编程自适应扫描融合软件定义网络与新的协同检测方法;这一新的安全措施可以使得微电网的互联具有超高的弹性和安全性、低成本与高度自动化等优点。协同检测结合了主动同步扫描和混沌检测两类新技术,可以有效识别电力机器人攻击的类型并对各类攻击快速定位,且不会中断或影响互联微电网的正常运行。可编程自适应安全扫描技术的有效性和实用性在大量实验中得到了确证。

The kinematic assumptions upon which the Euler-Bernoulli beam theory is founded allow it to be extended to more advanced analysis. Simple superposition allows for three-dimensional transverse loading. Using alternative constitutive equations can allow for viscoelastic or plastic beam deformation. Euler-Bernoulli beam theory can also be extended to the analysis of curved beams, beam buckling, composite beams and geometrically nonlinear beam deflection. In this study, solving the nonlinear differential equation governing the calculation of the large rotation deviation of the beam (or column) has been discussed. Previously to calculate the rotational deviation of the beam, the assumption is made that the angular deviation of the beam is small. By considering the small slope in the linearization of the governing differential equation, the solving is easy. The result of this simplification in some cases will lead to an excessive error. In this paper nonlinear differential equations governing on this system are solved analytically by Akbari-Ganji’s method (AGM). Moreover, in AGM by solving a set of algebraic equations, complicated nonlinear equations can easily be solved and without any mathematical operations such as integration solving. The solution of the problem can be obtained very simply and easily. Furthermore, to enhance the accuracy of the results, the Taylor expansion is not needed in most cases via AGM manner. Also, comparisons are made between AGM and numerical method (Runge-Kutta 4th). The results reveal that this method is very effective and simple, and can be applied for other nonlinear problems.

In the present paper, three complicated nonlinear differential equations in the field of vibration, which are Vanderpol, Rayleigh and Duffing equations, have been analyzed and solved completely by Algebraic Method (AGM). Investigating this kind of equations is a very hard task to do and the obtained solution is not accurate and reliable. This issue will be emerged after comparing the achieved solutions by numerical method (Runge-Kutte 4th). Based on the comparisons which have been made between the gained solutions by AGM and numerical method, it is possible to indicate that AGM can be successfully applied for various differential equations particularly for difficult ones. The results reveal that this method is not only very effective and simple, but also reliable, and can be applied for other complicated nonlinear problems.
