Challenges and Opportunities in 4D Printing -An Application Perspective

Over the last ten years, 3D printing technology has played a pivotal role in transforming the manufacturing industry. A recent advancement within the realm of 3D printing has introduced time as a fourth dimension, enabling the creation of 4D printing components. While a 3D-printed design remains static, a 4D-printed design has the remarkable ability to change its shape in response to environmental conditions. This paper also examines various applications of 4D printing across diverse fields such as electronics, renewable energy, aerospace, food, healthcare, and fashion. The review addresses research gaps, the current obstacles in 4D printing, and the future prospects of this technology

A Model-Based Approach to Comprehensive Risk Management for Medical Devices

The European medical technology industry consists of around 27,000 companies, more than 95% of them small and medium-sized enterprises (SMEs), with over 675,000 employees [MEDT17]. In the European Union (EU) alone, medical devices constituted by far the biggest part of the medical technology (MedTech) sector with a market of 95 billion euros in annual sales in 2015 [EURO15].The European medical technology industry consists of around 27,000 companies, more than 95% of them small and medium-sized enterprises (SMEs), with over 675,000 employees [MEDT17].

A critical review of the research literature on Six Sigma, Lean and StuderGroup's Hardwiring Excellence in the United States: the need to demonstrate and communicate the effectiveness of transformation strategies in healthcare

<p>Abstract</p> <p>Background</p> <p>U.S. healthcare organizations are confronted with numerous and varied transformational strategies promising improvements along all dimensions of quality and performance. This article examines the peer-reviewed literature from the U.S. for evidence of effectiveness among three current popular transformational strategies: Six Sigma, Lean/Toyota Production System, and Studer's Hardwiring Excellence.</p> <p>Methods</p> <p>The English language health, healthcare management, and organizational science literature (up to December 2007) indexed in Medline, Web of Science, ABI/Inform, Cochrane Library, CINAHL, and ERIC was reviewed for studies on the aforementioned transformation strategies in healthcare settings. Articles were included if they: appeared in a peer-reviewed journal; described a specific intervention; were not classified as a pilot study; provided quantitative data; and were not review articles. Nine references on Six Sigma, nine on Lean/Toyota Production System, and one on StuderGroup meet the study's eligibility criteria.</p> <p>Results</p> <p>The reviewed studies universally concluded the implementations of these transformation strategies were successful in improving a variety of healthcare related processes and outcomes. Additionally, the existing literature reflects a wide application of these transformation strategies in terms of both settings and problems. However, despite these positive features, the vast majority had methodological limitations that might undermine the validity of the results. Common features included: weak study designs, inappropriate analyses, and failures to rule out alternative hypotheses. Furthermore, frequently absent was any attention to changes in organizational culture or substantial evidence of lasting effects from these efforts.</p> <p>Conclusion</p> <p>Despite the current popularity of these strategies, few studies meet the inclusion criteria for this review. Furthermore, each could have been improved substantially in order to ensure the validity of the conclusions, demonstrate sustainability, investigate changes in organizational culture, or even how one strategy interfaced with other concurrent and subsequent transformation efforts. While informative results can be gleaned from less rigorous studies, improved design and analysis can more effectively guide healthcare leaders who are motivated to transform their organizations and convince others of the need to employ such strategies. Demanding more exacting evaluation of projects consultants, or partnerships with health management researchers in academic settings, can support such efforts.</p

Reliability Analysis of On-Demand High-Speed Machining

Current trends in high-speed machining aim to increase manufacturing efficiency by maximizing material removal rates and minimizing part cycle times. This project explores three related technologies and presents a system design for rapid production of custom machined parts. First a reliability analysis in high-speed machining of thin wall features is put forth with experimental results. Second an implementation of on-demand manufacturing is presented with emphasis on flexibility and automation. Finally innovative manufacturing cell design is used to drive costs down by optimizing material and information flow. The resulting high-speed on-demand machining cell design employs effective techniques to reduce production time, meet changing customer needs, and drive down costs

Annual Report 2017

Dear Friends, I am pleased to say the College of Engineering and Science (COES) at Louisiana Tech University is breaking new ground in a variety of ways. We are thrilled to announce that our new Integrated Engineering and Science Education building will likely start construction at the beginning of next year. The new 128,000 square-foot facility will greatly enhance our ability to provide an unparalleled education to our students and help attract the best faculty and staff to support our College’s future growth. We are also breaking new ground in our College’s academic programs. Our newest bachelor’s degree program, Instrumentation and Control Systems Engineering Technology, started this fall and now provides our engineering technology students a project-based, hands-on freshman curriculum similar to the Living with Lab curriculum that is taken by our first-year engineering majors. Our first in the nation bachelor’s degree program in Cyber Engineering is off to a solid start and continues to grow while it undergoes its initial accreditation review by ABET this year. We have recently expanded our online programs to offer a master’s degree in industrial engineering, as well as a graduate certificate in Six Sigma Black Belt training. As you will read in this report, our students are leading the way by establishing new student organizations like our Aerospace Engineering Club, creating new products and services through innovation and serving the people of our community. Our faculty are passionate about working with these students to help them become our country’s future leaders in engineering and science. We are particularly excited to have 19 new faculty in the College bringing their new ideas and energy to help us expand our efforts. As we continue to break new ground in preparing the BEST engineers and scientists for tomorrow, I would encourage you to stay connected with us, and I invite you to visit us in Ruston and see the impact that our students, faculty and staff are making in this world. Best Regards, Hisham Hegab, Ph.D.Dean and Thigpen Professorhttps://digitalcommons.latech.edu/coes-annual-reports/1003/thumbnail.jp
