With the evaluation of a next-generation human–machine interface (HMI) concept for excavators, this study aims to discuss the HMI quality measurement based on usability and user experience (UUX) metrics. Regarding the digital transformation of construction sites, future work environments will have to be capable of presenting various complex visual data and enabling efficient and safe interactivity while working. The evaluated HMI focused on introducing a touch display-based interface, providing advanced operation functions and different interaction modalities. The assessment of UUX should show whether the novel HMI can be utilised to perform typical tasks (usability) and how it is accepted and assessed in terms of non-instrumental qualities (user experience, UX). Using the collected data, this article also aims to contribute to the general discussion about the role of UX beyond usability in industrial applications and deepen the understanding of non-instrumental qualities when it comes to user-oriented process and machine design. The exploratory study examines insights into the application of elaborated UUX measuring tools like the User Experience Questionnaire (UEQ) on the interaction with industrial goods accompanied by their rating with other tools, namely System Usability Scale (SUS), Intuitive Interaction Questionnaire (INTUI) and the National Aeronautics and Space Administration (NASA) Task Load Index (NASA-TLX). Four goals are pursued in this study. The first goal is to compare in-depth two different ways of interaction with the novel HMI—namely one by a control pad on the right joystick and one by touch. Therefore, a sample of 17 subjects in total was split into two groups and differences in UUX measures were tested. Secondly, the performances of both groups were tested over the course of trials to investigate possible differences in detail. The third goal is to interpret measures of usability and user experience against existing benchmark values. Fourth and finally, we use the data gathered to analyse correlations between measures of UUX. The results of our study show that the different ways of interaction did not impact any of the measures taken. In terms of detailed performance analysis, both groups yielded differences in terms of time per action, but not between the groups. The comparison of UUX measures with benchmark values yielded mixed results. The UUX measures show some relevant significant correlations. The participants mostly reported enjoying the use of the HMI concept, but several practical issues (e.g., efficiency) still need to be overcome. Once again, the study confirms the urge of user inclusion in product development. Especially in the course of digitalisation, as big scale advancements of systems and user interfaces bring uncertainty for many manufacturers regarding whether or how a feature should be integrated.

The slicer control system designed for production plants to manufacture flap disks was investigated using programmable logic controller (PLC) and servo. This system has been mainly developed to achieve the automatic flaps’ cutting and setting. It is implemented by a PLC, a human-machine interface(HMI), a positioning module, and senors, as well as servo amplifiers and motors. In the present work, the effect of response time on multi-axis synchronization has been studied. It was shown that the use of parameter adjustment allows the obtainment of reliable operating characteristic and permits one to enormously improve the accuracy of feeding length and rotation angle. The control system has been provided for industrial applications.

In order to avoid the shortage of subjective judgment, carrying on the human-machine interface layout scientifically, this paper put forward that the genetic algorithm was applied to the layout design of oil rig driller console. Using real number coding, combining with human-machine interface layout principles to establish the mathematical model, genetic algorithm was adopted to optimize the layout. Developed an intelligent layout optimization system on basis of VB, and took the layout scheme formation process of the manipulators which on the right hand area of driller console as an example to explain the system. Theory and example analysis showed that the algorithm could generate the layout scheme quickly and effectively, solved the problem that layout principles were difficult to be quantize in the traditional layout design and the quality of layout was hard to judge, and to a certain extent, has realized automatic layout.

This research article focuses on the theme of violence and its representation by the characters of the novel “This Savage Song” by Victoria Schwab. How violence is transmitted through genes to next generations and to what extent socio- psycho factors are involved in it, has also been discussed. Similarly, in what manner violent events and deeds by the parents affect the psychology of children and how it inculcates aggressive behaviour in their minds has been studied. What role is played by the parents in grooming the personality of children and ultimately their decisions to choose the right or wrong way has been argued. In the light of the theory of Judith Harris, this research paper highlights all the phenomena involved: How the social hierarchy controls the behaviour. In addition, the aggressive approach of the people in their lives has been analyzed in the light of the study of second theorist Thomas W Blume. As the novel is a unique representation of supernatural characters, the monsters, which are the products of some cruel deeds, this research paper brings out different dimensions of human sufferings with respect to these supernatural beings. Moreover, the researcher also discusses that, in what manner the curse of violence creates an inevitable vicious cycle of cruel monsters that makes the life of the characters turbulent and miserable.

Feminist critics have celebrated Kate O'Brien's pioneering approach to gender and sexuality, yet there has been little exploration of her innovations of the coming-of-age narrative. Creating a modern Irish reworking of the Bildungsroman, O'Brien's heroines represent an idealized model of female identity-formation which stands in sharp contrast to the nationalist state's vision of Irish womanhood. Using Franco Moretti's theory of the Bildungsroman, a framing of the genre as a thoroughly ‘modern’ form of the novel, this article applies a critical Marxist lens to O'Brien's output. This reading brings to light the ways in which the limitations of the Bildungsroman work to constrain O'Brien's subversive politics. Their middle-class status remains an integral part of the identity of her heroines, informing the forms of liberation they seek. Fundamentally, O'Brien's idealization of aristocratic culture, elitist exceptionalism and ‘detachment of spirit’ restricts the emancipatory potential of her vision of Irish womanhood.
