DD-Pose: A large-scale Driver Head Pose Benchmark
No full textWe introduce DD-Pose, the Daimler TU Delft Driver Head Pose Benchmark, a large-scale and diverse benchmark for image-based head pose estimation and driver analysis. It contains 330k measurements from multiple cameras acquired by an in-car setup during naturalistic drives. Large out-of-plane head rotations and occlusions are induced by complex driving scenarios, such as parking and driver-pedestrian interactions. Precise head pose annotations are obtained by a motion capture sensor and a novel calibration device. A high resolution stereo driver camera is supplemented by a camera capturing the driver cabin. Together with steering wheel and vehicle motion information, DD-Pose paves the way for holistic driver analysis. Our experiments show that the new dataset offers a broad distribution of head poses, comprising an order of magnitude more samples of rare poses than a comparable dataset. By an analysis of a state-of-the-art head pose estimation method, we demonstrate the challenges offered by the benchmark. The dataset and evaluation code are made freely available to academic and non-profit institutions for non-commercial benchmarking purposes

Light-activated modulation and coupling in integrated polymer-liquid crystal systems
No full textWe explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device. The electrical properties and the strength of modulation are investigated as a function of the incident light intensity as well as the frequency and amplitude of the applied voltage, for two LCs with very different electrical conductivity. A simplified electrical model of the cell is proposed, demonstrating that the LC conductivity is a key factor determining the beam-coupling strength
Evidence for B-0 -> D+D- and observation of B-->(DD-)-D-0 and B-->(DD*-)-D-0 decays
No full textWe report evidence for B-0 -> D+D- and the first observation of the decay modes B-->(DD-)-D-0 and B-->(DD*-)-D-0 based on a sample of 152x10(6) B (B) over bar events collected by the Belle detector at KEKB. The branching fractions for B-0 -> D+D-, B-->(DD-)-D-0, and B-->(DD*-)-D-0 are found to be (1.91 +/- 0.51 +/- 0.30)x10(-4), (4.83 +/- 0.78 +/- 0.58)x10(-4), and (4.57 +/- 0.71 +/- 0.56)x10(-4), respectively. Charge asymmetries in the B-->(DD-)-D-0 and B-->(DD*-)-D-0 channels are consistent with zero
The Influence of Intellectual/Developmental Disabilities (I/DD) Curriculum Content on Career Interests for Social Work Students
No full textThis study examines how curriculum content on Intellectual/Developmental Disabilities (I/DD) impacts the career interests of social work students. With the growing demand for social workers proficient in I/DD services, it is crucial to understand how educational experiences shape career choices. Using a QUANT→Qual mixed-method approach, this quasi-experimental pre/post-test survey combined quantitative data (N 66 [experimental group]; N =103 [control group] and open-ended survey questions (N = 66 [experimental group]; N =103 [control group] from social work students.
The author-constructed survey assessed student attitudes, perceptions, preparedness, ability to identify I/DD, knowledge of I/DD, and willingness to practice with individuals with I/DD before and after exposure to I/DD-focused curriculum content over a 15-week period. The quantitative findings indicated that exposure to I/DD-focused curriculum content significantly improved students’ preparedness, ability to identify I/DD, knowledge about I/DD, and willingness to work with this population. Qualitative findings indicated that students who completed the I/DD courses reported increased confidence and interest in pursuing careers involving I/DD roles. The study findings emphasize the importance of including dedicated I/DD content in social work education to better equip future practitioners
Comparison of magnetic couplers for IPT-based EV charging using multi-objective optimization
No full textInductive power transfer (IPT) is becoming increasingly popular in stationary electric vehicle (EV) charging systems. In this paper, the influence of the different IPT coupler geometries on the performance factors such as efficiency, power density, misalignment tolerance, and stray field is studied. Four different coupler topologies, namely the circular, rectangular, double-D (DD-DD), and the double-D transmitter with double-D-quadrature receiver (DD-DDQ) are considered in this study. The electromagnetic behavior of the couplers is modeled using three-dimensional finite-element method, which is validated by experiments on a laboratory prototype. A multi-objective optimization (MOO) framework is developed to analyze the Pareto tradeoffs between conflicting performance metrics for the couplers. Optimization results depict that the circular topology performs best among the selected topologies regarding higher coupling coefficient, and efficiency for similar active mass and coupler area. Circular and rectangular couplers perform better than the polarized couplers like DD-DD and DD-DDQ regarding stray field exposure in both vertical and lateral direction of the coupler position in the EV. However, polarized couplers show more tolerance toward misalignment compared to circular and rectangular couplers. Thus, this study provides information regarding the specific strengths and weaknesses of different coupler topologies, which can be used during the initial design phase.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.DC systems, Energy conversion & Storag
Structure, (governance) and health: An unsolicited response
No full textBackground: In a recently published article, it was suggested that governance was the significant
structural factor affecting the epidemiology of HIV. This suggestion was made notwithstanding the
observed weak correlation between governance and HIV prevalence (r = .2). Unfortunately, the
paper raised but left unexamined the potentially more important questions about the relationship
between the broader health of populations and structural factors such as the national economy and
physical infrastructure.
Methods: Utilizing substantially the same data sources as the original article, the relationship
between population health (healthy life expectancy) and three structural factors (access to
improved water, GDP per capita, and governance) were examined in each of 176 countries.
Results: Governance was found to be significantly correlated with population health, as were GDP
per capita, and access to improved water. They were also found to be significantly correlated with
each other.
Conclusion: The findings are discussed with reference to the growing interest in structural factors
as an explanation for population health outcomes, and the relatively weak relationship between
governance and HIV prevalence
