Survivability is an important component in the requirements in elastic optical networks (EONs). We examine here the significance of network survivability design against multiple-link failures under dedicated protection, shared risk link group (SRLG) and bandwidth squeezing schemes. The proposed mixed integer linear programming (MILP) formulation seeks to derive some different types of protection considering routing, spectrum assignment, grooming, modulation format as well as shared risk link group constraints. The proposed MILP provides efficient survivability results and resource savings (in terms of spectrum) for a full design of modern EONs. © 2020 IEEE.

In this paper we present work towards automating two process steps supporting the optimization of the runnable-to-task mapping in automotive multi-core control units. We describe these steps in close relation to the AUTOSAR methodology to facilitate the integration with existing design processes. The first step is the automated generation of an initial configuration that balances the core utilization using constraint programming. The second step is the optimization of an existing configuration based on dynamic system behavior using an evolutionary algorithm. An abstract intermediate representation provides interoperability with existing AUTOSAR tools. We use a small case study to evaluate the feasibility of our approach.

In the last two decades, the importance of research on block-based programming education has grown. The use of block-based programming tools is receiving attention not only in computer science courses, but also in robotics education. The effects of such programming on children’s learning outcomes have been examined, but the results have been inconclusive. The purpose of this meta-analysis was to examine the mean effect of block-based programming compared with traditional instruction (i.e., text-based programming) on children’s learning outcomes, including problem-solving skills, programming skills, computational thinking and motivation. The effect size and effects of moderators (publication year, sample size, publication sources and study region) were also examined. The database search yielded 19 publications with 31 effect sizes (n = 1369). Block-based programming had a significantly larger effect size than did traditional instruction for overall learning outcomes. More specifically, we found a large effect size for problem-solving skills, small effect sizes for programming skills and computational thinking, and a trivial effect size for motivation. No moderating effect was detected. Effect sizes for outcomes were large in research conducted in the Americas and Asia, medium in studies conducted in Europe and trivial in studies conducted in the Middle East. No evidence of publication bias in the studies was detected. These study findings support the benefits of block-based programming education for children’s learning outcomes, especially their problem-solving skills. Future research should examine additional dependent variables. © 2020, Springer Nature Switzerland AG.

This paper introduces an application design named Planty Go which encourages young people to exchange their planting harvests in big cities to relieve anxiety. To achieve this target Planty Go offer youngsters a place to learn planting skills, exchange harvest, and make friends with people who also like planting. This paper also includes the process of the application design from research to evaluation. Different from other planting applications, Planty Go focuses on supporting the emotions of youngsters and planting experience. So this paper introduces how to identify the problem through primary research and how to solve those problems with the Planty Go. Finally, this paper introduced a Heuristic Evaluation which helps designers improve this design continually. © 2020, Springer Nature Switzerland AG.

This paper presents our contract-based design technique for formalizing requirements during the design phase of a complicated and safety-critical automotive component. In our approach, contracts are created using property specification patterns to eliminate ambiguous unstructured natural language requirements, which could lead to misinterpretations or mismatched interfaces in the integration phases of the design *** patterns are then automatically transformed into Signal Temporal logic (STL) formulas. The STL formulas are verified on a modeled system of the component, utilizing the Matlab® toolbox Breach. This approach validates the industrial requirements described in the contracts, and can help achieve the requirement-based testing demanded by automotive safety standard ISO 26262.

In 2018, at the 22nd international AIDS conference (AIDS 2018), the international AIDS Society (IAS)–Lancet Commission “Advancing global health and strengthening the HIV response in the era of the Sustainable Development Goals” laid out a bold vision for expansion of the HIV agenda with greater engagement and synergy between the movements for universal health care, non-communicable diseases, and more integrated responses to the pandemics of HIV, tuberculosis, and malaria.1,2 Our vision was challenging for many across these vital domains. In the USA, for example, the three public health leaders for COVID-19, Anthony Fauci of the US National Institutes of Health, Deborah Birx of the US President's Emergency Plan for AIDS Relief, and Robert Redfield of the US Centers for Disease Control and Prevention, are all distinguished HIV researchers and leaders. [...]to ensure full access to COVID-19-specific programming for global communities, those sessions will be made publicly available and free of charge.

In this paper, we describe techniques and considerations for using emoji effectively in educational programming tools. Introducing emoji gives users access to more than 3,000 different image assets for game and other application development. Since the font files installed in the user’s computer vary by its operating software and device vendor, it is preferable that programming tools bundle common emoji font files for users. Emojis have a variety of gender and skin color patterns, which reduces the artist’s effort to bring diversity to the illustrations of the people. Some emojis contain violent or vulgar expressions. Tool providers can filter some emojis to prevent children from accessing inappropriate emojis in schools, or they can adjust visuals to mitigate aggressiveness. Advanced visuals and applications can be obtained by extracting contour and geometry information or adding shadows. In order to help users quickly find the emoji they are looking for from many emojis, a utility system should be implemented that classifies emojis by category, searches for emojis by word, and suggests random emojis. © Springer Nature Switzerland AG 2020.
