CAx Integration and Its Design Application Based on Feature Extension of Sensor Components

In order to improve the information and product originality level of intelligent manufacturing industry based on sensor technology, this paper summarizes the current situation of CAx integration based on sensor technology and its design application and analyzes the shortcomings of existing CAx integration, aiming at accurate, complete, timely, and barrier-free transfer of sensor product data and information between CAx system and MRPII/ERP management information system. The concept and information model of feature extension of sensor components oriented to the whole process of sensor intelligent manufacturing is presented. Taking feature extension of sensor components as the integration link, CAx integration framework structure and its design application mode based on feature extension are established, while key technologies and implementation ideas to realize the integration and the design application are put forward, which provides an effective path to realize the sensor integration of CAx and management information systems such as MRPII/ERP.

Analysis and calculation of wooden framework structure by using Structural Analysis Program (SAP)-2000 and method of joint

Find out the force of the structure wooden framework is one indication in determining the dimensions of compression chord, tension chord, diagonal chord, and vertical chord. The value of each chord force is the main requirement in the planning dimension and joints connections in the structure planning of the wooden framework. Analysis/calculation of each of the chord forces in the wooden framework (tension chord, compression chord, vertical chord, and diagonal chord) using a method of joint and Structural Analysis Program (SAP-2000). Wooden framework span is 7 m, (α) = 30°, and the number of compression chord is 6. Results of the two methods will show the value of each of the chord force structures, the value of the chord force compared to see the accuracy of the structural analysis program. Analysis and calculation found the ratio of maximum and minimum value for each chord force using a method of joint and structural analysis program are 0.15 and 0. Based on research results, a Structural Analysis Program (SAP-2000) can be used to design and analyze a wooden framework, to simplify and save time in planning the structure of the wooden framework.

Sensing Properties of NH2-MIL-101 Series for Specific Amino Acids via Turn-On Fluorescence

Metal–organic frameworks (MOFs) have been demonstrated to be desired candidates for sensing definite species owing to their tunable composition, framework structure and functionality. In this work, the NH2-MIL-101 series was utilized for sensing specific amino acids. The results show that cysteine (Cys) can significantly enhance the fluorescence emission of NH2-MIL-101-Fe suspended in water, while NH2-MIL-101-Al exhibits the ability to sense lysine (Lys), arginine (Arg) and histidine (His) in aqueous media via turn-on fluorescence emission. Titration experiments ensure that NH2-MIL-101-Fe and NH2-MIL-101-Al can selectively and quantitatively detect these amino acids. The sensing mechanism was examined and discussed. The results of this study show that the metal centers in MOFs are crucial for sensing specific amino acids.
