Abstract
In this paper, it is described a multimedia interactive technology to enhance learning for children with learning disabilities. Developed with a user-centered design philosophy, it aims to present an easy user interaction environment to focus students on learning of reading and/or writing activities. With this purpose, it is described the solution developed and the usability assessment, through heuristics and user tests. The heuristics results revealed some minor problems in the design contents (that will be treated in a second version). However, the user tests showed children performed all tasks with success, not only in the offered time but also with no difficulty. Furthermore, they seemed satisfied and motivated to continue the interaction autonomously. © 2019 Association for Computing Machinery.

Abstract
Studies linking the use of lean practices to company performance have been increasing as markets are becoming more competitive and companies are eager for reducing waste and therefore implementing the Lean Management (LM) philosophy to improve performance. However, results from these studies have found various and different impacts and some light is needed. Extant literature was reviewed and, to achieve the research objective, a meta-analysis of correlations was carried out. The obtained results suggest a positive relationship between some lean practices and performance measures. Furthermore, the presence of moderators influencing the relationship between lean practices and performance outcomes is highlighted in our results. To our best knowledge, this is the first research that proposes a comparison of results from primary studies on Lean implementation, by analysing the linear relationship between lean practices and enterprise performance. It fills this gap and therefore represents an important contribution.

Abstract
Sustainable development has become an increasingly important theme not only in the world politics, but also an increasingly central theme for the engineering professions around the world. Software engineers are no exception as shown in various recent research studies. Despite the intensive research on green software, today’s undergraduate computing education often fails to address our environmental responsibility. In this paper, we present a module on energy efficient software that we introduced as part of an advanced course on software analysis and testing. In this module students study techniques and tools to analyze and optimize energy consumption of software systems. Preliminary results of the first four instances of this course show that students are able to optimize the energy consumption of software systems. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
Besides fuel and waste distribution, one core application of multi-compartment vehicles (MCVs) is the distribution of groceries, as they enable retailers to jointly transport products with different temperature requirements, thus reducing the number of visits to a store. Grocery stores usually define preferable time windows that depend on the temperature of products (for example, fresh products in the morning) to indicate when deliveries should occur to better plan their in-store operations. Distribution planning therefore needs to take these preferences into consideration to obtain consistent delivery times. This work extends the research on multi-compartment vehicle routing problems (MCVRPs) by tackling a multi-period setting with a product-oriented time window assignment. In this problem, a fleet of MCVs is used for distribution and a unique time window for the delivery of each product segment to each store is defined consistently throughout the planning horizon. An ALNS is proposed to solve the product-oriented time window assignment for MCVRP. Daily and weekly operators are developed respectively focusing on the improvement of routing aspects of the problem on each day and aligning the time window assignment consistently throughout the planning horizon. The approach is tested on benchmark instances from the literature to demonstrate its effectiveness. We also use direct information from retail practice and enhance this with simulated data to further generalize our findings. The numerical experiments demonstrate that planning consistent MCV distribution leads to better overall solutions than the ex-post time window assignment of daily plans, facilitating more on-time deliveries.

Abstract
This paper presents iMPAcT tool that tests recurring common behavior on Android mobile applications. The process followed combines exploration, reverse engineering and testing to automatically test Android mobile applications. The tool explores automatically the App by firing UI events. After each event fired, the tool checks if there are UI patterns present using a reverse engineering process. If a UI pattern is present, the tool runs the corresponding testing strategy (Test Pattern). During reverse engineering the tool uses a catalog of UI Patterns which describes recurring behavior (UI Patterns) to test and the corresponding test strategies (Test Patterns). This catalog may be extended in the future as needed (e.g., to deal with new interaction trends). This paper describes the implementation details of the iMPAcT tool, the catalog of patterns used, the outputs produced by the tool and the results of experiments performed in order to evaluate the overall testing approach. These results show that the overall testing approach is capable of finding failures on existing Android mobile applications.

Abstract
In this article, a self-referencing intensity-based fiber optic sensor relying on the principle of Fabry-Perot interference is proposed and demonstrated to measure curvature. The sensor is manufactured producing an air bubble cavity between two sections of multimode fiber. By detecting optical power variations at specific wavelengths, it was possible to measure curvature, enabling this sensor as a self-referencing system. For this setup, the achieved curvature sensitivity was 0.561 ± 0.014 dB/m-1, with a correlation factor up to 0.997, within the measurement range of 0.0-0.8 m-1. The proposed system has several features, including the self-referencing characteristic and its structure simplicity in terms of measuring procedure, making it a useful system. © 2017 IEEE.
