Towards perceptual metrics for audio quality assessment
… use different evaluation methodologies and metrics when reporting results, making a direct comparison to other systems difficult. Furthermore, in the case of objective metrics, the perceptual relevance and meaning of the reported metrics in most cases is unknown, prohibiting any conclusive …

Correlation of subjective and objective handling of vehicle behaviour
… find links between driver subjective ratings and objective measures of vehicle handling. The experimental data used in this project has been made available from a previous research project. The experimental data was collected using a prototype vehicle which was used in 16 different configurations. …

Quality and compressibility analysis of checkerboard-based digital halftoning algorithms
… is assessed using human surveys and statistical objective metrics. Correlations (or lack of) between the subjective and objective data are also observed. Image compressibility is studied via the C/C++ implementation of two new and original run length encoding (RLE) methods (Villarreal, 2001). …

Modelling the perception of percussive low frequency instruments in rooms
… topic. However, despite this, agap between objective metrics and subjective results is still prevalent, thus resultingin a limited understanding of perceived bass quality.Previous work has suggested a group of perceptual attributes that are useful indescribing the effect of room acoustics on …

Development of a Multi-Body Nonlinear Model for a Seat-Occupant System
… the ride comfort can be evaluated by a series of objective metrics in the dynamic response of the occupant. From previous studies it is well known that the dynamic behavior of a seat-occupant system is greatly affected by soft nonlinear viscoelastic materials used in the seat cushion. Therefore, …

Beyond the Bootstrap: Social and Cultural Capital in Hispanic Entrepreneurship
… human bias in lending and investment, using objective metrics as a social proxy for trust. Ultimately, I introduce the Beyond the Bootstrap Model. This framework shifts the community narrative from necessity-based entrepreneurship toward generational correction. A central discovery of this …

Context Dependent Gaze Metrics for Evaluation of Laparoscopic Surgery Manual Skills
… and qualification of laparoscopic skills through objective assessment has become critical. While eye-gaze and instrument motion analyses have demonstrated promise in producing objective metrics for skill assessment in laparoscopic surgery, three areas deserve further research attention. First, …

Computational Modeling Approaches For Task Analysis In Robotic-Assisted Surgery
… of technical skills earlier in training. Thus metrics for the skills, especially objective metrics, become crucial. One field of surgery where such techniques can be developed is robotic surgery, as here all movements are already digitalized and therefore easily susceptible to analysis. Robotic …

Assessing the Quality of Synthetic Speech when using Enhanced Speech as Training Data
… from noisy or enhanced speech using eleven objective quality metrics was also conducted. This investigation found that several common objective quality metrics used to evaluate speech enhancement also have relatively high correlations with subjective quality of utterances generated by speech …

Effects of Logic-Style Explanations and Uncertainty on Users’ Decisions
… numerous factors influencing subjective and objective metrics in the user-AI team, such as the effects of presenting AI-related information and explanations to users. Nevertheless, some factors that influence the effectiveness of explanations are still under-explored in the literature, such …

Machine learning and interactive real-time simulation for training on relevant total hip replacement skills.
… for orthopaedic surgical procedures lack objective metrics of assessment given a standard set of design requirements. Instead, most of them rely exclusively on the level of interaction and functionality provided. We propose a comparative assessment rubric based on three different …

Design and evaluation of real-time Voice-Over-IP (VOIP) systems with high perceptual conversational quality
… is a largely unexplored area. There are many objective metrics for assessing the quality of a VoIP conversation, but there is no single objective metric whose results match well with subjective results. Indiscriminate subjective testing is not feasible because it is prohibitively expensive to …

Finding perceptually optimal operating points of a real time interactive video-conferencing system
… at this point in time, there does not exist one objective quality metric that can accurately and fully describe the perceptual quality of a real time video conversation. Hence there is a need for a controlled environment to allow tests to be conducted in and in which we can study different …
