AbstractThe use of matrix algebra has expanded considerably in the last 25-30 years, in parallel with computer technology evolution. Introducing of matrix notation leads to simple and concise formulation of highly complex applications. In the first instance, a linear model can be developed or if the model is nonlinear, it can be linearized in first approximation, once or every step of a solving iterative process. In this paper, the authors will present two methods used to solve linear equations systems. First methods will be solved by manual calculation and the second method will be solved using a computer program, SISLIN, developed in Power Systems Department of the Politehnica University Timisoara. Methods are presented to students who are asked to apply the methods for case studies. Volume calculation is large, for which the authors analyze student’s concentration and attention degree.

This research addresses the types of assessment tasks, the assessment criteria, instruments and procedures of communicative competence used by primary school teachers in Andalusia. This multiple-case study drew on the experiences of teachers from four schools in the south of Spain. The data source has been the focus groups in which the teachers took part. The transcripts were analysed thematically by three researchers who devised a system of categories designed through an iterative process. The findings reveal the paucity of tasks used to assess reading, listening and oral expression. The study also shows the diverse problems faced by teachers when it comes to evaluating communicative competence. This paper highlights the need to rethink the curricular contents and the methods applied to assess communicative competence in primary schools.

Common Understanding

In this paper, we address the evolution of coordination between multiple and diverse partners in a complex R&D innovation project. Because common understanding is crucial to help coordination in complex and uncertain contexts, we performed an in-depth case study of a large European project aiming to investigate the interaction between common understanding and coordination mechanisms during the life cycle of a complex product systems (CoPS) multi-party project. We found that coordination mechanisms are combined according to different stages of the project and create common understanding by managing tasks and roles as the project unfolds. Moreover, to cope with high interdependent tasks and many diverse partners, it seems crucial to implement an iterative process where tasks and roles evolve and mature progressively, and problems are identified earlier, leading to a validated and consistent result.

High Dimensional Clustering

This paper develops a process whereby a high-dimensional clustering problem is solved using a neural network and a low-dimensional cluster diagram of the results is produced using the Mapper method from topological data analysis. The low-dimensional cluster diagram makes the neural network's solution to the high-dimensional clustering problem easy to visualize, interpret, and understand. As a case study, a clustering problem from a diabetes study is solved using a neural network. The clusters in this neural network are visualized using the Mapper method during several stages of the iterative process used to construct the neural network. The neural network and Mapper clustering diagram results for the diabetes study are validated by comparison to principal component analysis.

Conceptual synthesis is a creative, iterative process which allows nurse theorists to rigorously clarify the boundaries, nature, and attributes of a phenomenon. This challenging process is difficult and may be hindered if a linear approach is taken. Using metaphor as the lens through which conceptual synthesis is viewed, a cognitive whole among related ideas is seen. The purpose of this paper is to describe the use of metaphor as an enhancement to a traditional conceptual synthesis process to facilitate discovery. A case study and personal reflections illuminate the process and product. Implications for nursing practice, research, and theory construction are presented.

This article inductively builds theory on how transaction costs may be alleviated and institutional voids bridged in developing economies, based on the case study of successful migrant entrepreneurial involvement in Nigerian agriculture: Shonga Farms. We argue that the iterative process of building conditions of trust through long-term commitment, involvement of regional government, appropriate modes of financial contracts and the gradual transitioning of controlling interests to private actors are factors of success. We draw additional lessons by contrasting our case study with other similar migrant schemes that have failed.

Statistical Tolerance

Abstract This paper focuses on exploring an iterative method of statistical tolerance design to guide designers to select tolerances more economically and effectively. After having identified the assembly functional requirement (FR) and the functional elements (FEs) of corresponding tolerance chain, the expression of a unified Jacobian–Torsor model can be derived. Monte Carlo simulation is employed to generate random variables simulating the variations of small displacement torsor associated with the FE pairs with all the generated random values being within the intervals constrained by the corresponding tolerance zones. Then, the real multiplication operations are repeatedly executed to this model, a large number of real torsor component values of FR will be obtained and we can perform statistical analysis for these simulated data to get the statistical limits of the assembly FR in the desired direction. The tolerances of critical FEs may need to be adjusted to satisfy the assembly FR imposed by the designer, and the percentage contribution of each FE to the assembly FR can help determine these critical tolerances that need to be tightened or loosened. Once the calculated FR is in close agreement with the imposed FR, the iterative process can be stopped, and the statistical tolerance redesign is achieved. The effectiveness of the proposed method is illustrated with a case study. Compared with the deterministic tolerancing method, the results show that the proposed method is more economical and that can relax significantly the precision required, manufacturing and inspection costs can then be reduced considerably.

Purpose – This paper aims to describe a case study of how an unexpected event created an opportunity to reconsider and rewrite the methodology chapter in the author’s PhD thesis. Design/methodology/approach – The approach that the author used that assisted her to change her methodology involved a combination of reflective and reflexive reading, thinking and writing. It was a slow and thorough process through which the author considered widely the choices that she was making. Through an iterative process of writing, reading and talking, and then re-writing, the author was able to establish a position or standpoint from which she felt confident about the underpinnings of her study. Findings – The author came to understand herself ontologically in a new way. The author could see how she had moved significantly from a positivist view of static bodies of knowledge creation to a paradigm involving a more dynamic knowledge creation. Correspondingly, the author was able to revise and focus her methodology, and in the course of the process, she learnt and grew as a person and as a researcher. The author understood her values, assumptions and beliefs about the world much more clearly. The author also became much more aware of her own PhD journey, how she was developing personally and how her identity was evolving. Originality/value – This paper will be useful for those who are embarking on their PhD journey and attempting to critique and/or rethink their methodological approach in the qualitative or interpretivist paradigm.

This paper proposes a new bid based redispatching method to relieve congestion in a pool type market, based on bilateral generation exchanges between generation units. Sensitivity analysis is used to find and implement the cheapest consecutive bilateral exchanges that would remove congestion in an iterative process. Congestion cost is calculated as exchange cost during congestion removal and is divided between congested parts using load flow results in each iteration. Divided cost is recovered from consumers, based on their relative contributions on congested parts using generalized load distribution factors. IEEE 39 and 118 bus test systems are used for case study to evaluate the merits of proposed method and the results are discussed in comparison with other conventional methods.
