Abstract
Cervical cancer remains a significant cause of mortality in low-income countries. However, it can often be cured by removing the affected tissues when detected in early stages. Therefore, it is relevant to provide universal and efficient access to cervical screening programs, being digital colposcopy an inexpensive technique with high potential of scalability. The development of computer-aided diagnosis systems for the automated processing of digital colposcopies has gained the attention of the computer vision and machine learning communities in the last decade, giving origin to a wide diversity of tasks and computational solutions. However, there is a lack of a unified framework to discuss the main tasks and to assess their performance. Thus, in this paper, we studied the core research lines surrounding the automated analysis of digital colposcopies and built a topology of problems and techniques, including their key properties, advantages, and limitations. Also, we discussed the open challenges in the area and released a database that serves as a common basis to evaluate such systems.

Abstract
Though equal access to all digital devices, content and applications should be ensured by default in the Digital Age, reality has yet to match this ideal, despite the numerous efforts to raise awareness of the problem. For the visually impaired, the existence of e-accessibility issues represents a barrier that, in the majority of situations, cannot be overcome. Nevertheless, this group of individuals still insists on using digital devices, to carry out tasks from their daily lives, such as reading and writing e-mails, reading news and weather websites, and using social networks. This assumption has been validated through a survey completed by 29 blind or partially sighted individuals. Considering that the lack of depth of knowledge in developers constitutes one of the most significant constraints to the development of accessibility software and digital content, the proposal for “slide 0” to be included as an educational resource, when developers are learning how to engineer software, is discussed later in the paper. This contribution, if precisely focused on the various types of software projects, would represent a novel addition to the existing scientific literature, but also a comprehensive aid to the inclusion of e-accessibility when lecturing experts on software engineering. © 2018, Springer International Publishing AG, part of Springer Nature.

Abstract
The paper presents extension of model-based disturbance rejection method based on Magnitude optimum method. The original method requires the pre-chosen values of controller and compensator filter values, which might result in a relatively noisy process input signals that are not tolerated in practice. In order to keep the process input noise under control, the proposed tuning method requires user-defined controller and compensator noise gain for high frequencies, instead. The experiments on process models show that the proposed approach is successful even though the actual and the identified process models do not match.

Abstract
The aim of this paper is to analyse Brazil's tourism destination image taking into account travel agents and tour operators' perspectives. This paper thus seeks to complement previous research carried out based on travellers' viewpoints. This research, more specifically, sought to analyse the antecedents of Brazil's overall image from the perspective of Portuguese travel intermediaries. For that cognitive image, affective image and marketing communications were analysed as antecedents of Brazil's overall image, and visitation influence was modelled as a mediator. Based on a questionnaire completed by 132 Portuguese travel agents and tour operators, the results show that the total (direct and indirect) effect of both cognitive image and marketing communications are more important than the total effect of affective image. Moreover, the visitation influence exerts no mediation at all between affective image and overall destination image, although there is a mild partial mediation effect involving the other two antecedents (cognitive image and marketing communications).
