A group of multidisciplinary Purdue students are working together to design, assemble, and install a Biowall in the Children’s section of the West Lafayette Public Library. A Biowall is a plant-based filter that improves Indoor Environmental Quality by cleaning indoor air and adding a natural aesthetic to the building space. Purdue has been developing Biowall technology since 2012, and this project involves redesigning it to fit into the available space at the library. The new Biowall design incorporates a watering mechanism that allows for children to get actively involved in maintaining the Biowall and learning about sustainability. This project also allowed university students to participate in the design process, manufacturing, and commissioning of the Biowall. Future add-ons to the design include a display to show current Indoor Environmental Quality, buttons to light different sections of the Biowall for an immersed learning experience. The project involved the participation of two student organizations, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and Boiler Green Initiative (BGI). The students from these organizations were able to learn about the designing and assembly process, while also learning how a Biowall works. The team involved in the project includes Ph.D., Masters, and Undergraduate students. The students involved came from Mechanical Engineering, Mechanical Engineering Technology, Environmental Engineering, and Construction Management Technology. The project involves working with a community partner, West Lafayette Public Library, and working with Purdue Facilities Service Building (PSFB) to assemble the equipment. An undergraduate class also benefitted from the Biowall by leaning the commissioning process by taking measurements of the different components in the Biowall. Once assembled and tested at the Environmental Chamber in the Applied Energy Lab located at the Knoy Building, the Biowall will be moved and installed in the West Lafayette Public Library. The location allows for the public to learn about the research done by Purdue, the Biowall will be a tool for everyone to learn about the importance of Indoor Environmental Quality, contaminants in the indoor air, and plants that improve Indoor Air Quality. A website which includes more information about the Biowall will also be active with the installation of the Biowall, the website provides for more outreach opportunities. Detailed documentation will be provided to the Library with Standard Operating Procedures.

In the new stage for intelligent manufacturing of traditional Chinese medicine(TCM) from pilot demonstration to in-depth application and comprehensive promotion, how to raise the degree of intelligence for the process quality control system has become the bottleneck of the development of TCM production process control technology. This article has sorted out 226 TCM intelligent manufacturing projects that have been approved by the national and provincial governments since the implementation of the "Made in China 2025" plan and 145 related pharmaceutical enterprises. Then, the patents applied by these pharmaceutical enterprises were thoroughly retrieved, and 135 patents in terms of intelligent quality control technology in the production process were found. The technical details about intelligent quality control at both the unit levels such as cultivation, processing of crude herbs, preparation pretreatment, pharmaceutical preparations, and the production workshop level were reviewed from three aspects, i.e., intelligent quality sensing, intelligent process cognition, and intelligent process control. The results showed that intelligent quality control technologies have been preliminarily applied to the whole process of TCM production. The intelligence control of the extraction and concentration processes and the intelligent sensing of critical quality attributes are currently the focus of pharmaceutical enterprises. However, there is a lack of process cognitive patent technology for the TCM manufacturing process, which fails to meet the requirements of closed-loop integration of intelligent sensing and intelligent control technologies. It is suggested that in the future, with the help of artificial intelligence and machine learning methods, the process cognitive bottleneck of TCM production can be overcome, and the holistic quality formation mechanisms of TCM products can be elucidated. Moreover, key technologies for system integration and intelligent equipment are expected to be innovated and accelerated to enhance the quality uniformity and manufacturing reliability of TCM.

The issues of additive technology in relation to combined methods of tool manufacturing using electromagnetic and other types of fields as an influence on the process are considered. It is shown that the use of additive technologies in mechanical engineering is most promising for flexible-structured industries, where the products are in a state of constant improvement and updating, and are produced in a limited series. In this case, it is required systematic replacement of the tool, which ensures the receipt of parts with the required configuration and quality level. 1. The paper proposes a new approach to the use of additive technologies in combined processing methods, where the concept of a traditional tool in the form of a solid body having a mirror image of the working part relative to the treated surface is expanded to non-contact and non-force contact effects, in which the removal of the allowance and the change in operational characteristics occurs due to thermal, chemical, magnetic influences or their combinations with mechanical factors. 2. The ways of solving the problem of managing operational characteristics by creating parts from conjugate layers, the properties of which are formed by optimizing technological modes, are proposed. 3. The field of effective use of the technology of sequential layer-by-layer build-up or changing the properties of layers during contact and contactless processing on serial equipment without time-consuming readjustment or modernization of technological equipment by designing a software product for modern computing equipment is disclosed. 4.

Introduction A vast amount of applied technology relating to noise and vibration control has emerged over the last twenty years or so. It would be an impossible task to attempt to cover all this material in a text book aimed at providing the reader with a fundamental basis for noise and vibration analysis, let alone in a single chapter! This chapter is therefore only concerned with some of the more important fundamental considerations required for a systematic approach to engineering noise and vibration control, the main emphasis being the industrial environment. The reader is referred to Harris 4.1 for a detailed engineering-handbook-type coverage of existing noise control procedures, and to Harris and Crede 4.2 for a detailed engineering-handbook-type coverage of existing shock and vibration control procedures. Beranek 4.3 also covers a wide range of practical noise and vibration control procedures. Some of the more recent advances relating to specific areas of noise and vibration control are obviously not available in the handbook-type literature, and one has to refer to specialist research journals. A list of major international journals that publish research and development articles in noise and vibration control is presented in Appendix 1. This chapter commences with a discussion on noise and vibration measurement units. The emphasis is on the fundamental principles involved with the selection of objective and subjective sound measurement scales, vibration measurement scales, frequency analysis bandwidths, and the addition and subtraction of decibels.
