Use of quantum rods for display applications

We examined the use of quantum rods (QRs) in two configurations for display applications, including the backlight and emissive color pixels for liquid crystal and organic light‐emitting diode displays, respectively. For the backlight, we used an electrospun nanofiber sheet embedded with QRs, and found the nanofiber‐aligned sheet showed polarized emission with a very high outcoupling efficiency. We then fabricated emissive color pixels with QRs using an inkjet printer, and evaluated their optical properties. The color gamut area size was 82% of the BT2020 standard and the overlap with it was 69%.     

Satisfying quality requirements in the design of a partition‐based,distributed stock trading system

Although quality requirements (QRs) have become a major drive in today's software development, there have been very few real‐world examples in the literature that demonstrate how to meet these requirements. This paper presents such an example. Specifically, the paper describes the design of a partition‐based distributed stock trading service system that satisfies a set of QRs related to resource utilization, performance, scalability and availability. The paper evaluates this design through detailed experiments and discusses some design alternatives and the lessons learned. Central to this design are a static load distribution strategy and a dynamic load balancing strategy. The first strategy is to achieve an initial balanced workload on the system's server cluster during the system initialization time, whereas the second strategy is to maintain this balanced workload throughout the system execution time. Together, these two strategies work in unison to ensure that the server resources are efficiently utilized; the user requests are processed with the required speed; the application is partitioned with sufficient room to scale; and the system is highly available.

Developing and validating a physical product e-tailing systems success model

The study attempts to develop and validate a physical product e-tailing systems success model based on the existing information systems/e-commerce systems success models and consumer behavior literature. The proposed e-tailing success model describes the interrelationships among nine dimensions: Information Quality, System Quality, Service Quality, Product Quality, Perceived Price, Perceived Value, User Satisfaction, Intention to Reuse, and Electronic Word-of-Mouth. Data collected from 258 valid respondents are tested against the research model using the partial least squares approach. The results indicate that Information Quality, System Quality, Service Quality, Product Quality, and Perceived Price (i.e. e-tailers’ quality and price attributes) have a significant influence on both Perceived Value and User Satisfaction, and that Perceived Value significantly affects both Intention to Reuse and eWOM (i.e. customers’ loyalty) directly or indirectly through the mediation of User Satisfaction. The results of this study provide several important theoretical and practical implications for e-tailing systems success.     

Integrated Inspection of QoM,QoP, and QoS for AOI Industries in Metaverses

With the rapid development of information technologies such as digital twin, extended reality, and blockchain, the hype around "metaverse" is increasing at astronomical speed. However, much attention has been paid to its entertainment and social functions. Considering the openness and interoperability of metaverses, the market of quality inspection promises explosive growth. In this paper, taking advantage of metaverses, we first propose the concept of Automated Quality Inspection (AutoQI), which performs integrated inspection covering the entire manufacturing process, including Quality of Materials, Quality of Manufacturing (QoM), Quality of Products, Quality of Processes (QoP), Quality of Systems, and Quality of Services (QoS). Based on the scenarios engineering theory, we discuss how to perform interactions between metaverses and the physical world for virtual design instruction and physical validation feedback. Then we introduce a bottom-up inspection device development workflow with productivity tools offered by metaverses, making development more effective and efficient than ever. As the core of quality inspection, we propose Quality Transformers to complete detection task, while federated learning is integrated to regulate data sharing. In summary, we point out the development directions of quality inspection under metaverse tide.

The impact of Quality Indicators on the rating of Multi-objective Evolutionary Algorithms

Evaluating and comparing multi-objective optimizers is an important issue. But, when doing a comparison, it has to be noted that the results can be influenced highly by the selected Quality Indicator. Therefore, the impact of individual Quality Indicators on the ranking of Multi-objective Optimizers in the proposed method must be analyzed beforehand. In this paper the comparison of several different Quality Indicators with a method called Chess Rating System for Evolutionary Algorithms (CRS4EAs) was conducted in order to get a better insight on their characteristics and how they affect the ranking of Multi-objective Evolutionary Algorithms (MOEAs). Although it is expected that Quality Indicators with the same optimization goals would yield a similar ranking of MOEAs, it has been shown that results can be contradictory and significantly different. Consequently, revealing that claims about the superiority of one MOEA over another can be misleading.

Object oriented programming approach for quality improvement based on systematic diagram method

Systematic Diagram Method is a useful tool for many phases of Quality Control. The Systematic Diagram (SD) displays the means necessary to achieve specific goals and objectives, clarifies the essence of the problem by making the subject matter visible, and searches for the most suitable means of realizing objectives. The SD either breaks down the main subject into its basic elements and depicts goals or systematically shows the means and procedures necessary to successfully implement a given plan. In order to devise the SD, a thoroughly methodized information and its execution are necessary. Object-Oriented Programming (OOP) approach is proposed as the tool for this purpose. In this paper, we discuss how OOP can be used in implementing the SD method to improve quality in three phases of quality control, i.e., Quality Design, Quality Assurance and Quality Improvement.     

A quality management based on the Quality Model life cycle

Managing quality is a hard and expensive task that involves the execution and control of processes and techniques. For a good quality management, it is important to know the current state and the objective to be achieved. It is essential to take into account with a Quality Model that specifies the purposes of managing quality. QuEF (Quality Evaluation Framework) is a framework to manage quality in MDWE (Model-driven Web Engineering). This paper suggests managing quality but pointing out the Quality Model life cycle. The purpose is to converge toward a quality continuous improvement by means of reducing effort and time.

Quality evaluation for Model-Driven Web Engineering methodologies

ContextThere are lots of approaches or methodologies in the Model-Driven Web Engineering (MDWE) context to develop Web Applications without reaching a consensus on the use of standards and scarcity of both, practical experience and tool support.ObjectiveModel-Driven Web Engineering (MDWE) methodologies are constantly evolving. Moreover, Quality is a very important factor to identify within a methodology as it defines processes, techniques and artifacts to develop Web Applications. For this reason, when analyzing a methodology, it is not only necessary to evaluate quality, but also to find out how to improve it. The main goal of this paper is to develop a set of Quality Characteristics and Sub-Characteristics for MDWE approaches based on ISO/IEC standards.MethodFrom the software products context, some widely standards proposed, such as ISO/IEC 9126 or ISO/IEC 25000, suggest a Quality Model for software products, although up to now, there are no standard methods to assess quality on MDWE methodologies. Such methodologies can be organized into Properties, thus, a methodology has artifacts, processes and techniques. Then, each item is evaluated through a set of appropriate Quality Characteristics, depending on its nature. This paper proposes to evaluate a methodology as a product itself.ResultsThis paper recommends a set of Quality Characteristics and Sub-Characteristics based on these standards in order to evaluate MDWE methodologies quality. Additionally, it defines an agile way to relate these Quality Sub-Characteristics to Properties with the sole purpose of not only analyzing, but also assessing and improving MDWE methodologies.ConclusionsThe application of these Quality Characteristics and Sub-Characteristics could promote efficiency in methodologies since this kind of assessment enhances both the understanding of strengths and weaknesses of approaches.
