Abstract:

Vehicle dynamics quality is generally evaluated by two approaches: subjective evaluations using driver ratings and objective measurements of vehicle dynamics characteristics. In both approaches it is important to define features of vehicle dynamics in order to cover all aspects, but without redundancy. For this reason, the first part of the paper tries to summarize the principal qualities and to how they might be organized. In the second part, the paper describes those procedures that can be used to obtain objective quality indices. First of all, criteria used in subjective testing (questionnaire design, jury selection, etc.) are described. Then it is determined which manoeuvres can be performed, and which physical quantities should be considered, in order to obtain objective parameters that correlate with subjective evaluation. After this, the paper briefly describes the statistical technique used to identify which measured variables best correlate with vehicle dynamics qualities. In the third part, the paper contains a practical application of the objective index identification procedure regarding handling quality. Some examples are given about how these indices are used in different phases of a new car development, from target setting to target deployment, and in target achievement and verification during final tuning.

Abstract:

Quality of life and life satisfaction are topics that currently receive a great deal of attention across the globe. Many approaches exist, which use both qualitative and quantitative methods, to capture these phenomena. Historically, quality of life was measured exclusively by economic indicators. However, it is indisputable that other factors influence people’s life satisfaction, which is captured by subjective survey-based data. By contrast, objective data can easily be obtained and cover a wider range, in terms of population and area. In this research, the multiple fuzzy linear regression model is applied in order to explain the relationship between subjective life satisfaction and selected objective indicators used to evaluate quality of life. The great advantage of the fuzzy model lies in its ability to capture uncertainty, which is undoubtedly associated with the vague concept of subjective life satisfaction. The main outcome of the paper is the detection of indicators that have a statistically significant relationship with life satisfaction. Subsequently, a pan-European sub-national prediction of life satisfaction after the consideration of the most relevant input indicators was proposed, including the uncertainty associated with the prediction of such a phenomenon. The study revealed significant regional differences and similarities between the originally reported satisfaction of life and the predicted one. With the help of spatial and non-spatial statistics supported by visual analysis, it is possible to assess life satisfaction more precisely, while taking into account the ambiguity of the perception of life satisfaction. Additionally, predicted values supplemented with the uncertainty measure (fuzzy approach) and the synthesis of results in the form of European typology help to compare and contrast the results in a more useful manner than in existing studies.

Abstract:

The paper discusses how visual research methods that draw on ethnomethodology and conversation analysis can help sociologists to reveal how optometrists’ assess the clarity of their clients’ distance vision. It argues that the detailed analysis of video-recorded interactions in optometric consultation rooms can help reveal the practical organization of the ‘routine’ work through which optometrists examine and assess their clients’ sight. Save for the contribution of the paper to methodological discussions about the use of visual data for the analysis of the practical work of optometrists, the paper also demonstrates how video-based research can add to recent debates in organizational sociology, workplace studies, and practice theory as well as to discussions about service quality and quality of care in health-service settings.

Abstract:

This paper presents a summary of recent progress in compression, subjective assessment and objective quality measures of point cloud representations of three dimensional visual information. Different existing point cloud datasets, as well as discusses the protocols that have been proposed to evaluate the subjective quality of point cloud data. Several geometry and attribute point cloud data objective quality measures are also presented and described. A case study on the evaluation of subjective quality of point clouds in two laboratories is presented. Six original point clouds degraded with G-PCC and V-PCC point cloud compression and five degradation levels were subjectively evaluated, showing high inter-laboratory correlation. Furthermore, performance of several geometry-based objective quality measures applied to the same data are described, concluding that the highest correlation with subjective scores is obtained using point-to-plane measures. Finally, several current challenges and future research directions on point clouds compression and quality evaluation are discussed.

Abstract:

In recent years, people’s daily lives have become inseparable from a variety of electronic devices, especially mobile phones, which have undoubtedly become necessity in people’s daily lives. In this paper, we are looking for a reliable way to acquire visual quality of the display product so that we can improve the user’s experience with the display product. This paper proposes two major contributions: the first one is the establishment of a new subjective assessment database (DPQAD) of display products’ screen images. Specifically, we invited 57 inexperienced observers to rate 150 screen images showing the display product. At the same time, in order to improve the reliability of screen display quality score, we combined the single stimulation method with the stimulation comparison method to evaluate the newly created display products’ screen images database effectively. The second one is the development of a new no-reference image quality assessment (IQA) metric. For a given image of the display product, first our method extracts 27 features by analyzing the contrast, sharpness, brightness, etc., and then uses the regression module to obtain the visual quality score. Comprehensive experiments show that our method can evaluate natural scene images and screen content images at the same time. Moreover, compared with ten state-of-the-art IQA methods, our method shows obvious superiority on DPQAD.

Abstract:

PurposeThe purpose of this paper is to estimate and compare the service quality of the city bus service measured by two different approaches which are subjective service quality dimensions and objective service quality dimensions.Design/methodology/approachThe objective service quality dimensions have been estimated based on the benchmarking technique provided by the Ministry of Urban Development, India. For the analysis of subjective service quality dimensions, a questionnaire survey has been conducted to measure the users’ satisfaction and dissatisfaction about the service. The questionnaire consists of users’ socioeconomic characteristics and 23 questions related to city bus service quality dimensions. Questionnaire data have been analyzed by factor analysis, regression analysis and path analysis to find out the indicators representing subjective service quality dimensions. Finally, the overall service quality of the bus service has been determined based on both the measures.FindingsThe study indicates that the overall service quality of the bus service is different for subjective and objective analyses. While the objective measures show that the service quality is very good, the subjective measures indicate that the service is not doing well.Research limitations/implicationsThe analysis of the subjective dimensions is complicated. Analysis of the subjective dimensions needed more expertise and resources than the objective analysis.Originality/valueIn this study, the estimated service quality of the bus service is more reliable than the other methods as it comprises of both operators’ perspective and passengers’ expectations from the service.

Abstract:

Quality of life assessment has been proposed as a possible research tool for evaluating the life experiences of individuals in different cultures. The bulk of the literature on quality of life recognizes the existence of two separate but related measures of quality of life: objective measures (tangible and observable measures) and subjective measures (cognitive assessment or satisfaction with existing tangibles). The question is whether the subjective and objective measure of general quality of life of one culture can be used to assess or predict the quality of life in another. The current investigation suggests quality of life is best assessed within the context of the culture in which the individual resides and makes recommendations for social work education to reinforce cultural sensitivity through study abroad in order to prepare future social workers to meet the social service demands in a globalized world.

Abstract:

The interior noise samples from four cars at different positions and different speeds were selected as the evaluation objects. The subjective evaluation test of sound quality preference was carried out with paired comparison method. Several objective psycho-acoustical parameters of these samples were calculated. By way of linear correlation and multi-dimensional regression analysis, an equation between the subjective evaluation of noise preference and the objective psycho-acoustical parameters was established. The results indicate that the vehicle interior sound quality preference under the good highway and the constant-velocity driving conditions is affected mainly by two psycho-acoustical parameters Loudness and Sharpness.

Abstract:

During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. Subjective assessment has been based on the GRBAS scale. Objective assessment of the vocal organ used the HSDI technique (High Speed Digital Imaging). In the laryngeal visualization, high-speed camera (HS) using rigid endoscope with 90 ° optics has been used. Vibration of vocal folds has been recorded during phonation of vowel "e" at 4000 frames / sec. The glottal closure (GTs), symmetry, regularity and synchronization of vocal folds vibration have been assessed. In estimating the degree of glottal insufficiency, kymography of the larynx has been performed by analyzing the value of Open Quotient (OQ). Objective acoustic evaluation of voice has been also conducted using DiagnoScope Specjalista Program. Hoarseness has been observed in 15 pregnant women, whereas voice fatigability in 20 patients. Using HSDI, the edema of vocal folds in part of the group has been observed. Decreased MPT has been found in all examined women in the third trimester of pregnancy. Hoarseness and fatigability of voice are the most frequent subjective symptoms of voice organ in the third trimester of pregnancy. Decreased MPT is recorded objectively, as well as edema and insufficiency of vocal folds using HSDI technique.

Abstract:

This paper deals with the delay, delay variation - jitter, packet loss rate and bandwidth as quality of service parameters, in the form of four types of video quality degradations. The impact of defined levels of degradation on subjective impressions (given as mean opinion scores) is analyzed. ReTRiEVED video dataset with publicly available subjective scores is used in the analysis. Three full-reference measures are used for objective assessment of video quality. The degree of consistency of subjective and objective quality scores is shown through scatter plots and quantitative measures (linear correlation coefficient and correlation of the ranks). Based on the interpolation functions, quality of service parameters are mapped to subjective experience. We show that jitter is a much more destructive effect than other degradation types.

Abstract:

Objective object segmentation visual quality evaluation is an emergent member of the visual quality assessment family. It aims to develop an objective measure instead of a subjective survey to evaluate the object segmentation quality in agreement with human visual perception. It is an important benchmark for assessing and comparing the performances of object segmentation methods in terms of visual quality. Despite its essential role, sufficient study compared with other visual quality evaluation studies is still lacking. In this article, we propose a novel full-reference objective measure that includes a two-level single object segmentation visual quality measure and a pooling method for multiple object segmentation overall visual quality. The single object segmentation visual quality measure combines a pixel-level sub-measure and a region-level sub-measure for evaluating the similarity of area, shape, and object completeness between the segmentation result and the ground truth in terms of human visual perception. For the proposed multiple object segmentation overall visual quality pooling method, the rank of each object’s segmentation quality as a novel factor is integrated into the weighted harmonic mean to evaluate the overall quality. To evaluate the performance of our proposed measure, we tested it on an object segmentation subjective visual quality assessment database. The experimental results demonstrate that our proposed two-level measure and pooling method with good robustness perform better in matching subjective assessments compared with other state-of-the-art objective measures.

Abstract:

Abstract Broadcasting services seek to optimize their use of bandwidth in order to maximize user’s quality of experience. They aim to transmit high-quality digital speech and music signals at the lowest bitrate. They intend to offer the best quality under available conditions. Due to bandwidth limitations, audio quality is in conflict with the number of transmitted radio programs. This paper analyzes whether the quality of real-time digital DAB+ broadcasted radio programs surpasses the quality offered by analog FM radio. We also perform a subjective and objective quality assessment comparative study of the HE-AAC v2 audio codec used in DAB+. The subjective studies were carried out using the MOS test methodology, whereas the objective tests were realized using the ViSQOLAudio metric. These studies were followed by a questionnaire concerning the migration from analog to digital radio domain.

Abstract:

During any synchromesh development programme, reliable methods for evaluating and assessing the gear-shift quality are necessary. In order to overcome the reliance on a trained driver and associated subjective judgement, methods have been investigated to describe the gear-shift characteristics using objective, rather than subjective measures This paper describes the measurement and calculation of objective measures that relate to perceived shift quality. Examples are given on the use of these measures to evaluate the effect of production variability on shift quality, and to allow comparisons of shift quality to be made between competitive vehicles
