In contrast to text-independent speaker verification, which has received significant attention from researchers and has many competitions dedicated to it, text-dependent speaker verification (TdSV) has been less explored recently. The TdSV Challenge 2024 was organized to analyze and explore novel methods for this type of speaker verification and aims to motivate participants to develop new approaches to TdSV, conduct comprehensive analyses, and investigate advanced techniques such as self-supervised learning. This challenge builds on the achievements of the short-duration speaker verification (SdSV) Challenges held in 2020 and 2021 and focuses specifically on TdSV in two distinct scenarios. The first scenario involves conventional TdSV, while the second focuses on speaker enrollment using user-defined passphrases. This paper provides a detailed description of both tasks, introduces the evaluation rules, and presents a comprehensive analysis of the results obtained from this challenge. © 2025 IEEE.

Driver state sensing technologies, such as vehicular systems, start to be widely considered by automotive manufacturers. To reduce the cost and minimize the intrusiveness towards driving, the majority of these systems rely on the in-cabin camera(s) and other optical sensors. With their great capabilities in detecting and intervening of driver distraction and inattention,these technologies may become key components in future vehicle safety and control systems. However, to the best of our knowledge,currently, there is no common standard available to objectively compare the performance of these technologies. Thus, it is imperative to develop one standardized process for evaluation *** this paper, we propose one systematic and standardized evaluation process after successfully addressing three difficulties:1) defining and selecting the important influential individual and environmental factors, 2) countering the effects of individual differences and randomness in driver behaviors, and 3) building a reliable in-vehicle driver head motion tracking tool to collect ground-truth motion data. We have collected data on a large scale on a commercial driver state-sensing platform. For each subject, 30 to 40 minutes of head motion data was collected and included variables, such as lighting conditions, head/face features,and camera locations. The collected data was analyzed based on a proposed performance measure. The results show that the developed process can efficiently evaluate an individual camerabased driver state sensing product, which builds a common base for comparing the performance of different systems.

Developing good research questions is a skill that develops over time and is often difficult for students. More often than not, it is up to the student to determine what to research. Where do I start? What do I look for? Is this a good research question? These are just a few of the questions students ask and should ask in the early stages of their research process. This work describes a progressive plan for developing research questions using a series of four design activity worksheets to guide students through the cognitive and metacognitive processes of choosing topics, asking questions, identifying an appropriate problem and locating adequate data sources. The worksheets are introduced in a linear manner and completed in order. This progressive path is intended to provide a logical and methodical approach for developing research questions. However, each worksheet can be completed independently. The worksheets can also be used as a pedagogical approach to introduce research methods into the classroom. The design activity worksheets have been used in multiple venues: undergraduate and graduate data visualization courses, workshops and more recently, a graduate seminar designed to help students identify their thesis topics in partial fulfillment of their graduate degree. In this work, we describe the development and characteristics of the worksheets and report some preliminary results of a study designed to assess their perceived impact and usefulness from a student's perspective. © American Society for Engineering Education 2020.

Visual conventions are perceptually efficient graphic agreements with common-sense like referents and are commonly used in what we interact with in daily life. It becomes a studying-worthy issue on whether such conventions can enhance performances and reduce cognitive load when we perceive and reason about new knowledge. Furthermore, whether the visual conventions can affect experts, who have prior knowledge and design experience about different visual encoding principles the same degree as novice who have no background knowledge in this area, is another research focus in this study. Our research is carried out according to action features when we read visualizations. Four task features are extracted, based on which behavioral and eye-tracking measurement were conducted, that is data localization, simple and complex data comparison, and knowledge inference. Both expert and novice participants were enrolled in our experiment. The result indicates that conventional elements in visualizations can hugely improve performances in more complex tasks involving higher-level cognition, like making comparisons and reasoning about new knowledge. The performance improvement can be seen from shorter response time on achieving conclusions and higher accuracy rates. Meanwhile, cognitive load, which can be measured from shorter total fixation duration and fewer fixation counts in AOIs, is reduced through applying visually conventional features. No statistically significant difference is found in comparing perceptual and inferential outputs of expert and novice group. We draw conclusions that visual conventions in visualizations can better performance in relatively complex activities, and it can be equally perceived and acquired regardless of the user’s knowledge background is. What we conclude in this study can be extended to areas of dynamic data visualization and layout design in the digital interface domain. © Springer International Publishing AG 2017.

This is a research paper. Investigating the use of design strategies is one of the most important approaches in understanding the design thinking processes of students in engineering design. Understanding students' use of design strategies-specifically, generating ideas, conducting experiments, revising and iterating, and troubleshooting-allows educators to better help students improve in their design thinking processes. In this study, we aimed to investigate and characterize students' use of four design strategies while they were designing with an educational CAD tool. Using students' captured videos and think-aloud transcripts, we have identified and characterized patterns of students' four design strategies. In this study, we have classified students into five categories based on their design patterns and descriptively identified the least and most prominent patterns students implemented. © American Society for Engineering Education 2020.

Automotive spark-ignition engines are great platforms for studying a variety of sensors, actuators, and control algorithms, but the size, expense, and maintenance required for an automotive engine coupled with a dynamometer test cell are impractical for many engineering and engineering technology programs. This paper proposes a portable engine-dynamometer test cell using a one-cylinder all-terrain vehicle (ATV) engine driving a set of high-current alternators. Engine loading is to be accomplished with a set of electric resistance heaters and a power switching array. Although associated with a large university, this project is being undertaken by a satellite campus with limited space and financial resources. The plan is to implement the Engine-Dyno Project in phases over a period of years using primarily undergraduate students working on directed projects. The planned phases at this time are as follows: 1. Build a sturdy but portable cart to hold the engine, load cell, accessories, and controls. (This phase is complete.) 2. Install the engine and get it running with no load (complete). 3. Construct a thermoelectric loading system and test the engine using manual switching of the electrical load. 4. Implement and test an electronic control system to dynamically adjust loading. 5. Implement and test a dynamometer control and data acquisition system to perform automated test runs while recording data. 6. Convert the engine to electronic ignition and fuel injection and run baseline tests. 7. Design and implement an engine control system with user-programmable ignition and fuel system parameters, and appropriate test points for monitoring sensor data and controlling actuators. 8. Develop labs for the following courses: Introduction to Automotive Electronics, ECET 38501 (lecture) and ECET 38502 (lab), Heat and Power, MET 22000, and Applied Thermodynamics, MET 32000. The paper begins with background information about how the Engine-Dyno project came about along with a high-
