Mining Potential Requirements by Calculation of User Operations

This study proposes a method for mining potential user requirements from users’ nonverbal behaviors by analyzing their operational problems, since human behaviors reflect emotions and operational bottlenecks in human-machine interactions. Taking a single daily operation task as an example, three key steps were included in the method: first, modeling users’ operation and constructing the operation chain; second, finding emotional or physical problems in the operation chain, where the problems were defined mathematically as an emotional or physical load at each suboperation; and third, defining and obtaining potential user requirements by improving the operational problems when performing a task. Furthermore, a daily operation task was introduced to demonstrate and validate the method of mining user potential requirements. The results indicate that it is effective to discover the potential needs for a specific product and provide satisfactory solutions by calculating and optimizing operational problems.

Topology optimization using PETSc: a Python wrapper and extended functionality

This paper presents a Python wrapper and extended functionality of the parallel topology optimization framework introduced by Aage et al. (Topology optimization using PETSc: an easy-to-use, fully parallel, open source topology optimization framework. Struct Multidiscip Optim 51(3):565–572, 2015). The Python interface, which simplifies the problem definition, is intended to expand the potential user base and to ease the use of large-scale topology optimization for educational purposes. The functionality of the topology optimization framework is extended to include passive domains and local volume constraints among others, which contributes to its usability to real-world design applications. The functionality is demonstrated via the cantilever beam, bracket and torsion ball examples. Several tests are provided which can be used to verify the proper installation and for evaluating the performance of the user’s system setup. The open-source code is available at https://github.com/thsmit/, repository $$\texttt {TopOpt\_in\_PETSc\_wrapped\_in\_Python}$$ TopOpt _ in _ PETSc _ wrapped _ in _ Python .

A Longitudinal Study of Pervasive Display Personalisation

Widespread sensing devices enable a world in which physical spaces become personalised in the presence of mobile users. An important example of such personalisation is the use of pervasive displays to show content that matches the requirements of proximate viewers. Despite prior work on prototype systems that use mobile devices to personalise displays, no significant attempts to trial such systems have been carried out. In this article, we report on our experiences of designing, developing and operating the world’s first comprehensive display personalisation service for mobile users. Through a set of rigorous quantitative measures and 11 potential user/stakeholder interviews, we demonstrate the success of the platform in realising display personalisation, and offer a series of reflections to inform the design of future systems.

A reflection on the design and user acceptance of Tamil talk

Tamil talk is a speech to text application and was designed from a perspective of language and philosophy. This paper takes an indigenous approach in reflecting on the design and user acceptance of Tamil talk. The paper makes use of literature in critically reflecting on the design and the potential user acceptance of the application. It takes a multi-disciplinary approach and explores the influence of factors like language shift, language maintenance and philosophy in the context of user acceptance of speech to text. The application may appeal to a section of the native Tamil speakers as suggested in the literature but there are complex challenges that needs further research. Further research shall be in developing the application that conforms to the conceptual framework and widely test with the native speakers to arrive at a more precise prediction of user acceptance.

Child-resistant features of pharmaceutical packaging in the egyptian and global market; a comparative study

Child-Resistant packaging is substantial requirement especially when it is related to pharmaceuticals. Children under five years old are the most groups in risk of drug poisoning, as a result of their constant passion and attracting their attention to medicines, especially the distinctive color and small size. Due to the presence of medicines for adults, especially chronic diseases that require the presence of the drug always at home with exciting properties for the passion of a young child who is affected by colors and the small size which they can insert easily into their mouths. The child-resistant features attached to packages may present a problem (e.g., how to open the package) to its potential user (child or adult). Many of these features are used with the primary packaging and less for the secondary ones. Are these features efficient with available cost or not. Evaluation of each one might be varied according to package structure, level and child behavior. Therefore, the importance of adding some features in the pharmaceutical packaging Child-Resistant, in order to achieve the safety of children with a targeted age (children under 5 years old). By adding these special properties to the pharmaceutical packaging it will affect the design of the pharmaceutical packaging. Finally, this paper aimed to review and evaluate the child resistant features & securing methods that are used with pharmaceutical products in the Egyptian market, with which are available globally, then make a comparison between them by description and analysis.

How Users Responded to a Responsive Dictionary

The Thesaurus of Modern Slovene is a responsive dictionary: it is compiled automatically from existing language resources while further developments of the dictionary include user participation. Many of the features introduced by the responsive model are new to the Slovene language community (e.g. data is extracted automatically and includes some errors; nonexperts are involved in dictionary compilation; the resource is never truly finished). With financial support from the Slovene Ministry of culture, a survey was conducted to gauge (potential) user opinions on the new features. The paper presents the results of the survey (n = 671) including statistical analyses of dependencies between the respondents’ opinions and their reported familiarity with the new dictionary, their age, and their professional occupation.

The Solar Orbiter Heliospheric Imager (SoloHI)

Aims. We present the design and pre-launch performance of the Solar Orbiter Heliospheric Imager (SoloHI) which is an instrument prepared for inclusion in the ESA/NASA Solar Orbiter mission, currently scheduled for launch in 2020.Methods. The goal of this paper is to provide details of the SoloHI instrument concept, design, and pre-flight performance to give the potential user of the data a better understanding of how the observations are collected and the sources that contribute to the signal.Results. The paper discusses the science objectives, including the SoloHI-specific aspects, before presenting the design concepts, which include the optics, mechanical, thermal, electrical, and ground processing. Finally, a list of planned data products is also presented.Conclusions. The performance measurements of the various instrument parameters meet or exceed the requirements derived from the mission science objectives. SoloHI is poised to take its place as a vital contributor to the science success of the Solar Orbiter mission.
