<span>Much effort has been spent on developing and producing multimedia systems, with insufficient attention to ensure their quality This paper discusses different aspects of quality evaluation of multimedia systems, covering both cognitive and technical issues. The evaluation is viewed from three main perspectives: the product itself, how the product is used and the impacts of the product. Some relevant evaluation models for effective learning - in particular, objective-based, decision-based, value-based and naturalistic approaches - are examined and adapted for the purpose.</span>

The main research objective of the chapter is to provide an analysis of the technological quality evaluation models and make a proposal for a method suitable for the multiple criteria evaluation (decision making) and optimization of the components of e-learning systems (i.e. learning software), including Learning Objects, Learning Object Repositories, and Virtual Learning Environments. Both the learning software ‘internal quality’ and ‘quality in use’ technological evaluation criteria are analyzed in the chapter and are incorporated into comprehensive quality evaluation models. The learning software quality evaluation criteria are further investigated in terms of their optimal parameters, and an additive utility function based on experts’ judgements, including multicriteria evaluation, numerical ratings, and weights, is applied to optimize the learning software according to particular learners’ needs.

Cloud manufacturing is emerging as a new intelligent and collaborative manufacturing model. With the development of virtualization technology, the manufacturing resources can be encapsulated as manufacturing cloud services (MCSs). The accuracy of service quality evaluation is the key to selecting a MCS from many available ones with similar functions but different QoS, but existing QoS evaluation models only focuses on common service attributes, which cannot meet user needs. Hence, this paper presents an execution framework for domain-oriented QoS evaluation for MCSs. Four function modules for domain-oriented QoS evaluation of MCSs were analyzed, and the involving key technologies were discussed as well.

The article considers the use of smart technologies in the training of future professionals. The functions of smart-technologies are covered. It is emphasized that smart-technologies are successfully used in the field of education and training. A special place is occupied by computer educational multimedia systems, which allow to deepen knowledge, reduce the duration of training, increase the number of students per teacher. Improving the effectiveness of training in modern free economic education is impossible without the introduction of smart-technologies in the organization of the educational process. The function of smart-technologies and multimedia technologies is that they use a source of new content information, take on certain functions of both teacher and student, have the characteristics of different types of visualization. If interactive information is presented through a multimedia projector on an interactive whiteboard, the effectiveness of learning is significantly improved Multimedia systems are successfully used today in the field of education and training. A special place is occupied by computer educational multimedia systems, which allow to deepen knowledge, reduce the duration of training, increase the number of students per teacher. Improving the efficiency of education in modern free economic education is impossible without the introduction of new forms of organization of the educational process. Thus, future professionals will constantly use multimedia technologies in their professional activities. It is important to teach students to use them correctly, to acquaint them with the maximum benefits of these learning tools and valuable information resources. High school teachers need to be clear that multimedia technology is a powerful and effective learning tool that allows for more diversified methods of involving students in education.

The paper proposes a design and construction of a special plated capacitor exhibiting very good high-frequency characteristics. The capacitor is designed to minimize the parasitic parameters like ESR (equivalent series resistance) and ESL (equivalent series inductance) and to be suitable for power industry applications. The paper describes the fabrication process and discusses technical issues related to technology of manufacturing and assembling. It also provides an experimental verification and the quality evaluation based on frequency characteristics compared to existing commercial high-quality capacitor.

Multiformat and modality interfaces have become popular and effective tools for presenting information in training and instructional systems. Technological innovation, however, has far surpassed researchers’ understanding of how and under what circumstances these technologies are useful towards information gathering. Some recent research has begun to characterize the cognitive mechanisms that may be responsible for the comprehension and memory advantages typically seen with multimedia learning, as well as the role of individual differences in this process. Other work has defined effective pedagogical practices, such as instructional content and organization, for producing engaging and effective learning experiences. This chapter attempts to bridge these two research areas and provides concrete design recommendations for current instructional practice and directions for future research.

At present, the usual image definition evaluation methods are poor in focusing precision and have a lot of calculations. In view of these problems, the paper analyzed the factors affecting an image quality evaluation, and proposed two evaluation models based on an image contrast change rate and an autocorrelation function. These methods avoided efficiently the phenomenon of partial peaks of focusing-function curves for noise disturbing. The stimulant test proves that the focusing curve of the evaluation model in the paper has many advantages, such as good focusing performance, strong antijamming ability, good real time and so on.
