- This paper reports on a cross-cultural analysis of central accreditation requirements for engineering programs—focusing especially on issues related to social impact, social responsibility, and social analysis—in four different countries: Australia, China, Sweden and the United States. Upon comparing and contrasting the accreditation requirements documents and their treatment of “social” capabilities, we found that: I. Accreditation requirements in all four countries are similarly oriented to specific student-learning outcomes, where technical and social capabilities represent roughly equal proportions of the total number of requirements. II. Social capabilities represent a wide range of competencies, including very high-order social-analytic competencies (e.g., understanding the relationship between engineering and its social context). III. Important variations can be identified in how social capabilities are understood, with four distinct categories emerging: Social capabilities 1) as constraints, 2) as awareness, 3) as responsibility, and 4) as cultivation. After reviewing, categorizing, and analyzing the key ways social-analytic competencies are articulated and understood in the four countries’ accreditation documents, we identify key opportunities and challenges facing those seeking better integration of social competencies in engineering education. We conclude the paper with a review of our findings and our next steps.

Forskningsöversikt (refereegranskat)abstract
- Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative efforts, scientific breakthroughs can be made sooner and capitalized for the betterment of humanity.

Technical-Social Integration in Engineering Education: Comparing Accreditation Requirements in Australia, China, Sweden, and the United States
- 2012

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This project analyzes accreditation documents in four countries—Australia, China, Sweden, and the US—as a way to explore opportunities for and barriers to integrating technical and social aspects of engineering education. The cross-national comparison also seeks to shed light on the following two questions: 1. How can accreditation facilitate the education of socially competent engineers through encouraging the integration of technical and social aspects of engineering education? 2. What capabilities do different nations expect from engineers?

Experimental study on immersion phase change cooling of lithium-ion batteries based on R1233ZD(E)/ethanol mixed refrigerant

Tidskriftsartikel (refereegranskat)abstract
- To improve heat dissipation and temperature uniformity for the lithium-ion battery module of electric vehicle, the immersion phase change cooling characteristics of R1233ZD(E)/Ethanol mixed refrigerant were studied experimentally in a staggered battery module, which is composed of 50 batteries. At 101.3 kPa saturated vapor pressure, coupled wall boiling and forced convection heat transfer was analyzed under different discharge rates (1 C, 2 C, and 3 C), filling volume fractions of R1233ZD(E) (0.463, 0.540, 0.630, 0.735, and 0.857), and inlet volume flow rates (652.0, 1086.0, 1521.0, and 2172.0 mL min- 1). Meanwhile, the outlet vapor quality of the two-phase flow was calculated according to energy conservation. The results show that the heat generation of the battery was dominated by the operating current. With the decrease of the output power of the battery, the heat generation first increases rapidly, then increases gently, and finally decreases sharply. When low boiling point R1233ZD(E) was mixed into ethanol, wall boiling heat transfer was effectively enhanced, and the temperature uniformity of the battery module could be improved by up to 57.0\%. However, the outlet vapor quality of the two-phase flow showed that when the volume fraction of R1233ZD(E) exceeded 0.803, wall boiling departed from the nucleate boiling regime as well as heat transfer and temperature quantities changed accordingly. Forced convection heat transfer of liquid-phase played a leading role in reducing the temperature rise of the battery module, and its contribution increased with the increase of refrigerant inlet flow rate. When the inlet flow rate increased from 652.0 mL min- 1 to 1086.0 mL min- 1, the module temperature rise decreased by 14.8%. Nevertheless, forced convection of liquid-phase weakened battery wall boiling, which adversely affected the temperature uniformity of the battery module.
