Subjective Assessment of Image Compression Artefacts on Stereoscopic Display
… with a flicker paradigm were undertaken to do a subjective assessment of the visibility of compression artefacts of two sets of images with two codecs viewed on a stereoscopic display. For one set of images the result shows that artefacts can be silenced in some stereo images relative to 2D while …

An investigation on subjective assessments of workload and postural stability under conditions of joint mental and physical demands
… has been no work towards developing a single subjective method of evaluation. Select subjective assessment methodologies were evaluated quantitatively during laboratory-based experiments. Concurrent execution of mental and physical activity was required at various levels, since it was desired …

Active sampling, scaling and dataset merging for large-scale image quality assessment
The field of subjective assessment is concerned with eliciting human judgements about a set of stimuli. Collecting such data is costly and time-consuming, especially when the subjective study is to be conducted in a controlled environment and using a specialized equipment. Thus, data from these …

An Economic Theory of Insurance Regulation
… the type of rate regulatory law in effect and a subjective assessment of the restrictiveness of administration of regulation in a state. The four theories tested are capture theory, minimization of conflict, maximization of political support, and agency theory. The analysis is based on private …

Development of a model to predict discomfort in a vehicle due to vibration
… provides Health guidance caution zones for risk assessment. The human discomfort threshold limits are not given in this standard. Human discomfort, in general, is defined by measurements based on a shaker table and seat combination. These results when used for “in vehicle situations” may not …

Fixed Crown Prosthetic Treatment in Childhood – Functional Aspects /// Неснемаемо коронково протезиране в детска възраст – функционални аспекти
… in frontal sectors of the dentition. By the subjective assessment of the children and their parents from the prosthetic treatment, the final result of the crown prosthesis was evaluated on the three medio-biological indicators - prophylaxis, function, and aesthetics. On the basis of an …

Data-driven path filtering in ConceptNet
… to predict path quality from crowdsourced human assessments. Since a generic task-independent notion of quality is concerned, human participants are asked to rank paths according to their subjective assessment of the paths' naturalness, without being given specific definitions or guidelines. …

Differentiation of Central Auditory Processing Disorder and Attention-Deficit Hyperactivity Disorder in Children and Adolescents
… one another on the basis of both objective and subjective assessment of attention and behavior. First, children and adolescents diagnosed with ADHD, CAPD, and concomitant ADHD/CAPD were compared to participants with emotional problems on measures of attention/concentration, depression, anxiety, …

When the cat's (far) away... the effect of control centralization and compensation interdependence on performance misreporting
… likely to reduce sensitivity to differences in subjective assessment of a control’s detection likelihood resulting from control centralization. Consistent with this reasoning, I find that the difference in the extent of performance misreporting between a centralized and decentralized control is …

An evaluation of five physical activity assessment methods in a group of women
… five different methods of physical activity assessment in a group of adult females, aged 20 to 65 years. Perceived physical activity was obtained by completion of self- and interviewer-administered seven-day activity recall surveys. Within three weeks, self report diary and motion sensing …

Development of an artificial neural network model to predict expert judgement of leather handle from instrumentally measured parameters
… to investigate the relationship between the subjective assessment of leather handle and its measureable physical characteristics. Two collections of commercial leather samples provided by TFL and PITTARDS were studied in this project. While the handle of the TFL collection covered a varied …

Advanced Algorithmic Approaches for Improving Image Quality in 2D and 3D Holographic Displays
… image quality. Extensive objective and subjective assessment of experimentally reconstructed images reveal that the perceived quality improves considerably should the appropriate IQM loss be selected. Finally, the gradient descent method is extended to 3D hologram generation. While …

Measuring the value of workspace architectural design : construction of the Workspace Communication Suitability Index (WOCSIT)
… assumes a suitability rating as a result of subjective assessment of what range of values is acceptable for it to be "suitable" or relevant to ICP. Evaluation schemata, scoring devices derived from the index, can then be used to generate scores for different workspace artifacts and can either …

Evaluation of GLEAMS considering parameter uncertainty
… from the GLEAMS nonpoint source pollution model. Assessment of both the procedure and model was made by comparing absolute and relative predictions made with both probabilistic and deterministic procedures. Field data used came from a study of pesticide fate and transport in both no-till and …

A quantitative analysis and assessment of the performance of image quality metrics
Image quality assessment addresses the distortion levels and the perceptual quality of a restored or corrupted image. A plethora of metrics has been developed to that end. The usual mean of success of an image quality metric is their ability to agree with the opinions of human subjects, often …

Effects of In-Vehicle Information Systems (IVIS) Tasks on the Information Processing Demands of a Commercial Vehicle Operations (CVO) Driver
… performance, secondary task performance, and subjective assessment. The findings of this study strongly suggest that paragraphs should not be used under any circumstance to present information to the driver while the vehicle is in motion. On the other hand, the Graphics with Icons represent …

Human response to vibration from earthmoving machines.
… survey of drivers was completed to obtain their subjective assessment of vibration received. Analysis and cross correlation of measured and survey data confirm that discomfort and fatigue will be experienced by the drivers of these machines. The study also provided evidence that the large …

Effect of the number of breakfasts and the amount of breakfast consumed by 4th grade children on total daily nutrient and energy intake
… Methods: The Spears Point of Sale Dietary Assessment Tool (Spears POS-DAT) was used to determine which subjective dietary assessment tool was most accurate: 24-hour recall or food record. Breakfast and lunch was collected for 7 school days at an elementary school with the Spears POS-DAT. …
