The automotive seat market is positioned to significantly grow over the next five years. Research into how sensor implementation in every day driver cars can enhance driver wellness is becoming increasingly popular and visible in the automotive seat industry. However, in the competitive race car industry,?drivers prioritize driving ability over wellness. To further examine this phenomenon, the Human-Machine Interaction?Lab at the Georgia Institute of Technology took a unique approach to developing strong use cases for implementing sensor technology to improve driving ability for race car drivers by combining qualitative and quantitative research data obtained through modern design research and planning methodology. Following a process relying heavily on user-centered design methods, the authors developed a business case concept?for?a sensor-based seat accessory that acts as a competitive racer’s?driving coach?that is able to identify the mechanics of braking, turning, and accelerating through pressure sensors in the driver’s seat pan surface. This technology allows drivers to precisely understand when and how hard to brake, turn, or accelerate out of turns, thus reducing heat times and financial burden for drivers. 展开更多

The integration of academic research methodologies into design thinking processes presents a transformative approach to addressing complex challenges in group housing,fostering inclusive,sustainable,and user-centered solutions.This research explores how methodologies such as Participatory Action Research,post-occupancy evaluations,and Research through Design can be systematically embedded within design thinking to bridge the gap between academic rigor and empathy-driven,iterative design practices.By synthesizing these paradigms,the study proposes a framework for group housing design that prioritizes co-design processes,empathy-based data collection,and participatory evaluation,while emphasizing adaptability through sociocultural insights and user feedback.Case studies analysis demonstrate the effectiveness of flexible,community-driven design,while emerging technologies like IoT-enabled cohousing signal new opportunities for innovation.Challenges,including scalability,long-term validation,and reconciling user autonomy with professional expertise,are critically analyzed.Ultimately,this research advances a hybrid methodology to redefine the conceptualization,implementation,and assessment of group housing,offering actionable pathways to achieve affordable,inclusive,and context-sensitive housing solutions. 展开更多

Purpose:Learning to do research has been understudied in the context of professional development in postgraduate programs.This exploratory study investigated the agency and experiences of five Chinese students who learned to design their research project in a Master of Education program at an English-medium university in Hong Kong SAR.Design/Approach/Methods:We obtained the data from semi-structured interviews and documents to establish data triangulation.Findings:The findings revealed that(1)the students’agency in research design and proposal writing was associated with their personal/professional backgrounds,(2)their English proficiency affected their agency in the proposal writing,(3)the supervisors’feedback would stimulate students’agency in changing/refining their research design,and(4)ineffective supervision and learning resources would impede students’achievement of agency on their way to creating a robust research design.Originality/Value:This study adds empirical evidence to the field of research training through the lens of learner agency.It demonstrates the applicability of using the ecological framework of agency in theoretically interpreting the contextual facilitators and constraints in making postgraduate students active agents. 展开更多

A new kind of cutting movement trajectory is gi ven whose actual cutting efficiency is near to 100%. It can reduce the energy w earing greatly, and the surface quality of the product is improved to the utmost extent. The design mechanism of the optimal cutting movement trajectory system structure is analyzed incisively. At the same time, the principle of the complex movement of horizontal movement and swing is researched. The optimal design scheme of th e cutting movement trajectory system structure is set up. The choice method to g et the superior value of the movement system structure is found. The mathematics function formula is established which exhibits the relationship between the par ameter of the complex movement structure and that of the system movement structu re. By the formula, the precision value of the offset can be figured out. The r ule is adapted to different types of energy-saving stone-sawing machines. The complex movement structure of horizontal movement and swing is designed to f ulfill the cutting movement. It can make the saw frame move up with the hanging pod deviating from the vertical direction. At the same time, the saw frame have a down-movement. Then the sum of the two movements is near to zero, and the saw blade and the stone can keep in touch during the whole horizontal cutting. The result is that the actual cutting efficiency is 100%. Also, when the hanging pod moves to the limited position, the saw frame can keep the original inertia, and continue to swing up. It makes the back-cutting have high energy-storing. The optimal design of the eccentricity balance wheel is done. The mathematics fo rmula for expressing the movement system structure is deduced. The calculation m ethod and formula is set up which is used to get the value of important componen ts such as offset. The choice method and formula of elasticity distortion coeffi cient is set up when the saw frame moves smoothly. It is concluded that the offs et is the key dimension to actualize the optimal cutting movement trajectory. The resolving of the technical problems discussed above offers a theoretic and technical basis for optimal design of energy-saving stone-sawing machines. 展开更多

Alzheimer’s disease and related dementias have made a considerable impact on society, and can take a significant toll on familial caregivers. Recent successful caregiving interventions suggest a promising future, though informed research design, a priori, is paramount in ensuring quality results that the Government and public may use to make informed policy and personal healthcare decisions. Research designs including basic science, randomized controlled trials (RCTs), qualitative, and quasi-experimental designs serve as the primary basis for discussion with literary examples and caveats. 展开更多

Safety systems, built on state-of-the-art technology, are essential for achieving acceptable levels of plant safety to minimize hazards to the reactor and the general public. The second shutdown system(SSS) as an engineered safety feature and a part of the reactor protection system(RPS) is a means for rapidly shutting down a nuclear reactor, keeping it in a subcritical state and serving as a backup to the first shutdown system(FSS). In this research, one SSS with two types of optimum chamber designs is proposed that take into account the main current characteristic features of the Tehran research reactor with improvements over earlier designs. They are based on a liquid neutron absorber injection that is preferably different, diverse, and independent from the FSS based on the rod drop mechanism. The major design characteristics of this SSS with two different chambers were investigated using MCNPX 2.6.0 code. The performed calculations showed that the designed SSS is a reliable shutdown system, assuring an appropriate shutdown margin and injection time, with no significant effects on the effective delayed neutron fraction while causing minimal variations to the core structure. Further, the reasonable financial cost and the prolongation of the operation cycle are additional advantages of this design. 展开更多
