As predictive capabilities advance and human-model fidelity increases, so must validation of such predictions and models. However, subjective validation is sufficient only as an initial indicator; thorough, systematic studies must be conducted as well. Thus, the purpose of this paper is to validate postures that are determined using single-objective optimization (SOO) and multi-objective optimi...

The subjective visual vertical is determined when a subject judges the orientation of an indicator (e.g. a short line segment) as apparently vertical. The mechanisms that underlie this perceptual performance are usually assumed to be based predominantly on bottom-up processing of primarily vestibular and visual information. However, it is also possible that top-down processes play a role in suc...

Subjective methods are widely used to evaluate Multimedia Conferencing quality, yet when used in isolation the results can be misleading. Therefore, this research is measuring physiological indicators of stress (GSR, HR & BVP) as an indicator of the user cost of the reception quality of a multimedia conference. These measurements are taken as part of a 3-Dimensional approach, which incorporates...

Based on rural informatization connotation and five essential elements that affect rural informatization assessment, which are development environment, information infrastructure, information resource, information service system and application of information technology in rural areas, This paper designs an indicator system for rural informatization level assessment. Through AHP method, it sets...

Chills (goose bumps) have been repeatedly associated with positive emotional peaks. Chills seem to be related to distinct musical structures and the reward system in the brain. A new approach that uses chills as indicators of individual emotional peaks is discussed. Chill reactions of 95 participants in response to seven music pieces were recorded. Subjective intensity as well as physiological ...

Using perception of quality of life survey by Eurostat we construct the City Ecosystem Index (CEI) – a systemic indicator that measures subjective well-being in European cities. The purpose of the index is to inform public, policy-makers and entrepreneurs by providing a holistic view on subjective well-being across European cities. Once contrasted with the Global and Regional Systems of Entrepr...

This paper presents a preliminary study that relates the ability in performing remote control tasks with 3D video feedback and the users’ quality of experience (QoE) when users are asked to judge the video quality only. The QoE has been evaluated by means of traditional subjective quality experiments, while an objective performance indicator (alignment error) has been used in the remote control...

We investigate people’s attitudes towards the possible use of mobile negotiation support systems (NSS) in different social contexts and the consequences for their design. For that purpose we developed an online survey based on existing models of technology acceptance. In the questionnaire we showed five filmed scenarios of NSS use contexts. The data collected from 120 respondents, showed (a) th...

In this paper, we present denoising algorithm using wavelet packet transform based on VAD(Voice Activity Detection). For the purpose, the weighting parameter estimation method based on speech dominant indicator and the modified Berouti’s method are suggested. Subjective evaluation shows that the performance of the proposed algorithm with wavelet bases is better than that with Fourier basis.

Bone marrow cellularity was measured using the Quantimet 720 Image Analyser in 50 biopsy samples. In haematologically normal subjects the percentage cellularity of the marrow was between 40 and 63%. Subjective assessment of cellularity was an unreliable indicator of the quantitative measure.
