The study investigated the synergistic effects of green tea extract (GTE) and black rice extract (BRE) on total phenolic content, flavonoid content, antioxidant activities and angiotensin-converting enzyme (ACE) inhibition. The influence of GTE concentrations (14.64–85.36 % w/w) and pH levels (3.59–6.41) was analyzed by regression and response surface methodology. Optimized conditions of synergistic effect (85.36 % w/w GTE and 14.64 % of BRE at pH 6.0) yielded the highest antioxidant activities (DPPH IC₅₀ = 0.112±0.015 mg/mL, ABTS = 89.14±1.58 mmol TE/100 g, FRAP = 373.66±3.42 mmol Fe²⁺/100 g), the highest total phenolic (120.98±1.60 mmol GAE/100 g), flavonoid contents (15.28±1.07 mmol QE/100 g) and ACE inhibitory activity (IC₅₀ = 6.125±0.106 μg/mL). Therefore, this condition was selected to produce the combined extract for determining the combination index (CI). The CI was 0.349±0.075 for DPPH and 0.505±0.019 for ACE inhibition, indicating confirmation of a synergistic effect. These findings suggest that the combined extract could serve as a valuable functional ingredient, enhancing access to bioactive-rich resources for nutritionally supportive and sustainable diets. With potential applications in food systems and healthcare, this agro-ingredient may contribute to improved access to resources for blood pressure management and non-communicable disease (NCDs) prevention, aligning with broader goals in nutrition and health equity. © 2025

With a glulam-based post-beam building system, a variety of building solutions is offered on the market for multi-story buildings. The building system must be adaptable to the demands of each project. However, short lead-time, efficient manufacturing and assembly must be ensured. The use of product platforms has been acknowledged as an enabler to manage external (customer) and internal (production) efficiency. The building system cannot be locked to a set of standard components as a high level of customisation is required. A set of methods and tools is needed to support the design work and to ensure that solutions stay inside the boundaries of the platform definition. The aim of this work is to map the state-of-practice in the design phase for a glulam building system from a platform theory perspective and outline a path forward for applying a sustainable platform development in companies where a component-based product platform does not suffice. Empirical data were gathered from an on-going product platform development including interviews and document analysis. The results show the lack of definition in platform-based product development from a theoretical perspective and need for development of support methods for design that align with different production strategies. © IGLC 2018 - Proceedings of the 26th Annual Conference of the International Group for Lean Construction: Evolving Lean Construction Towards Mature production Management Across Cultures and Frontiers.

Business survival and growth is critically dependent upon the ability to develop new products and services, yet there has been a distinct scarcity of educational programs whose overarching focus is product development. With support from the NSF and the Center for Innovation in product development (CIPD) at MIT, a university consortium was formed in 1998 to disseminate a Master of Science program focused on product development leadership. This paper reviews the evolution of "PD21", the "Education Consortium for product development Leadership in the 21st Century," from creation of the template Master's degree program at MIT and formation of the consortium, to the transfer of curriculum to three other member schools (RIT, the University of Detroit-Mercy, and the Naval Postgraduate School), to the future of the consortium.1 Attention is given to the complexities and challenges associated with collaboration within and between universities.

2003 ASEE Annual Conference and Exposition: Staying in Tune with engineering Education

作者： Watkins, Todd A. Ochs, John B. Snyder, Drew M. College of Business and Economics Lehigh University Department of Mechanical Engineering Lehigh University Department of Art Lehigh University Lehigh University Intgd. Product Development Program Department Art

This paper discusses one part of our attempts at Lehigh University to put active, inquiry-based, collaborative, multidisciplinary experiences at the center of undergraduate education, starting in the freshman year. We briefly outline the goals, history, structure, and our evaluation of our Integrated Business and engineering Freshman Workshop, a team-project-based learning course emphasizing entrepreneurial product development. The main goal of the Workshop, and the interdisciplinary curricula which it leads into, is to enable graduates to move more rapidly along their chosen career paths, graduating both competent in their functional disciplines - whether business or engineering - and better prepared for long-term success. Freshmen, by and large, come as a blank slate in terms of disciplinary biases and expectations about college "coursework." By working in teams on original entrepreneurial, multi-disciplinary product development projects from the first year, students not only become multi-functional, self-directed and team-oriented, but better understand the context of the latter courses in their curricula. The program emphasizes higher-order skill development, including: problem and task identification in ill-defined problems;decision making under uncertainty and lack of information;integrating, connecting, and reflecting on diverse areas of knowledge;and written and oral communication. We also evaluate our progress based on several related sources of qualitative and quantitative assessment information. The paper concludes by exploring the major issues and lessons learned in program implementation.

A Reynolds-Averaged Navier-Stokes (RANS) method has been employed in conjunction with a chimera moving grid approach to provide accurate resolution of four-quadrant propeller flows under both the design and off-design conditions. Time-domain simulations were performed first for the DTRC 4118 propeller under ahead, bollard-pull, crash-ahead, crash-astern, and backing conditions and compared with the available experimental data. Preliminary numerical results were also presented for the DTRC 4383 propeller to illustrate the applicability of the chimera RANS method for highly skewed propellers.

Modern urban planning not only has to coordinate the needs of many different inhabitants and traffic participants, but also faces other challenges such as modal shift towards sustainable transportation. A comprehensive database of historical traffic, which would facilitate a decision based on data, is lacking in many cities. This became clear in consultation with our partners from the city of Krefeld. A novel method is the use of public available traffic information such as traffic colors or travel time data from navigation providers. In this contribution a method is applied to estimate the travel duration from the traffic colors on city level. Here we show for the first time how it can be applied cost-effectively and how the accuracy can be estimated in combination with a validation of the database by test drives for urban streets. It will also be investigated, whether speed variation has an influence on the estimation of driving time. We found out that this influence is negligible for the investigated example and the mean deviation of estimation accuracy from the measured values is less than six percent. Based on these promising results, it is possible to build up a database for improved urban and traffic planning at low cost. This can lead to better information for all traffic participants, thus, an improved traffic flow control could result in a reduction of car traffic emissions in the end.

In competitive segments like automobile and bus manufacturing industries, quality of vehicles need to be improved constantly to meet internal and external market demands. Compliance with international standard regulations for electronic equipment require expensive tests as part of the design and certification processes. In this work, a methodology to simulate electromagnetic compatibility tests is proposed, enabling cost reduction during certification, and consequently reducing development time. Two different printed-circuit-board layouts of a DC/DC-converter case study are compared through measurements and simulations to validate the methodology. © 2019 IEEE.

Despite decades of disaggregated initiatives aimed at improving the well-being and quality of life of its employees, their families, communities and stakeholders, many high-technology firms are still struggling to develop an integrated approach to address the triple bottom line aspects of sustainability. In particular how sustainability is being integrated into the product development process, and the challenges that result, is of interest to this work. A literature review into the role of internal factors of how a firm implements a sustainability strategy revealed that it was too normative to guide the implementation of a corporate sustainability strategy at the level of the product development value chain. Therefore, to better understand how senior and mid-level managers actually implement such a strategy, a case study was conducted at two business divisions of two different large, multinational firms that are relatively early in their development of an integrated sustainability strategy. The findings provide insight into the role of internal factors at the level of a business division as it attempts to incorporate sustainability into its product development value chain. © 2009 by ASME.

One of the most challenging issues for a self-sustaining robotic system is how to use its limited resources to accomplish a large variety of tasks. The scope of such tasks could include transportation, exploration, construction, inspection, maintenance, in-situ resource utilization, and support for astronauts. This paper proposes a modular and reconfigurable solution for this challenge by allowing a robot to support multiple modes of locomotion and select the appropriate mode for the task at hand. This solution relies on robots that are made of reconfigurable modules. Each locomotion mode consists of a set of characteristics for the environment type, speed, turning-ability, energy-efficiency, and recoverability from failures. This paper demonstrates a solution using the SuperBot robot that combines advantages from M-TRAN, CONRO, ATRON, and other chain-based and lattice-based robots. At the present, a single real SuperBot module can move, turn, sidewind, maneuver, and travel on batteries up to 500 m on carpet in an office environment. In physics-based simulation, SuperBot modules can perform multimodal locomotions such as snake, caterpillar, insect, spider, rolling track, H-walker, etc. It can move at speeds of up to 1.0 m/s on flat terrain using less than 6 W per module, and climb slopes of no less 40 degrees.

The demand for high speed electrical machines has increased recently, mainly in the electric or hybrid vehicles applications. Speeds as high as 13.000 rpm may be required, demanding new grades of electrical steels with improved magnetic properties. Such magnetic properties are typically characterized using parameters such as B50 and W10/400. However, improvements in these parameters do not necessarily translate into improvements of practical significance. This paper focuses on the performance improvements from newly developed electrical steels for high speed motors. Prototype motors were built for practical validation of the performance of these steels. Practical tests and finite element analysis are used to support the conclusions of this research work. © 2014 IEEE.
