The study is carried out to examine the interrelationship among the capital formation mechanism, formal socialization, informal socialization and the supply chain rational outcome. The study has used the social capital theory to conceptualize interrelationship among the capital formation mechanism, formal socialization, informal socialization and the supply chain rational outcome. The study has employed the SEM-PLS to answer the questions raised in the study.

Requirements engineering is often the first stage in the software process to understand the problem statement. Finding mistakes earlier in requirements helps reduce the development cost. This paper presents a classification approach of functional and non-functional requirements in Vietnamese using different supervised machine learning techniques.

The study stands on the standpoint that there exist close and essential relationships between real-world structures and their information provided to human beings in reality. The study gives a survey to summarize specific distinguishing fundamental features of HA-formalism, its applicability in problem-solving, and its performance and advantages.

In the paper "A verification framework for specification centered developments", we propose a verification framework for specification centered developments. In this framework, we firstly focus on improve the quality of specification then use such high-quality specification to drive the verification of the design and the implementation. This framework could be applied in domain of reactive systems with high automation, adaptation, and practicality.

Chapter 17 describes the use of general mathematical notations used in software engineering to specify and analyze abstract descriptions of interactive systems. In the previous chapter we looked at the specification of dialog. In this chapter we will look at ways of modeling the semantics of an interactive system. The dialog just tells us about what user actions are legal at any point, but here we will be interested in what the user’s actions do to the system.

This chapter has focussed on modeling the deeper semantic behavior of an interactive system. To design a usable system one needs to know what it does! We began by looking at different kinds of software engineering formalisms that can be used to specify the behavior of specific systems.

. In this paper, after redefining and developing simple formal definition for Composable Application Model (CAM), we present a matchmaking method that could be useful for verifying the correctness of software composition as well as for checking the correct deployment of a software composition on specified cloud platforms. As an illustration, we experimentally transform the cloud application model achieved by our matchmaking method into TOSCA-based specification template, which is known as a standard representation for multi-cloud applications.
