In lung cancer computer-aided diagnosis (CAD) systems, having an accurate ground truth is critical and time consuming. Due to lack of ground truth and semantic information, lung CAD systems are not progressing in the manner these are supposed to. In this study, we have explored Lung Image Database Consortium (LIDC) database containing annotated pulmonary computed tomography (CT) scans, and we have used semantic and content-based image retrieval (CBIR) approach to exploit the limited amount of diagnostically labeled data in order to annotate unlabeled images with diagnoses. We evaluated the method by various combinations of lung nodule sets as queries and retrieves similar nodules from the diagnostically labeled dataset. In calculating the precision of this system Diagnosed dataset and computer-predicted malignancy data are used as ground truth for the undiagnosed query nodules. Our results indicate that CBIR expansion is an effective method for labeling undiagnosed images in order to improve the performance of CAD systems while tested on PGIMER data. Also a little knowledge of biopsy confirmed cases can also assist the physician’s as second opinion to mark the undiagnosed cases and avoid unnecessary biopsies

We make a proposal to teach the concept of function using mobile computing. This proposal is based on research that has support in education theories such as Constructivism and Problem Solving Learning. In the first part we show the difficulties that undergraduate Computer Science students have in the first semester of Engineering while working with that mathematical concept. And application to be used by the students anywhere and anytime in mobile devices is designed that process data and is intended to show them the concept of function in a problem solving situation. The proposed activities are part of the education methodology used in the research and within this paper we show the diagnostic questionnaire as one of the methodological tools and its results supporting the designed activities and its application to mobile devices

Since its invention, robots have been developed for various purposes and needs, quite similar to personal computers in their early days. However, with the advancement of technology, it is anticipated that in near future one of the cutting-edge technologies to be used in “language teaching and learning” is robotics. Humanoid and/or animal shaped robots will soon gain more attention as a fancy tool for 1st and 2nd language teaching in mid-schools/high schools around the globe. At CEDRA, we are currently exploring the design and application of educational service robots to initiate and pioneer Robotics Assisted Language Learning (RALL) in Iranian schools. With the proliferation of computers and mobile devices, Computer Assisted Language Learning (CALL) and Mobile Assisted Language Learning (MALL) have been in the limelight for 2nd language instructional theories for about a decade or more. However, utilizing robots to support language teaching and learning can certainly enhance today's conventional techniques. Robots not only have the features and interfaces already being employed in CALL/MALL, but are also capable of autonomous movements, visual/voice recognition, and physical/ environmental interactions when equipped with various sensors. Although computers or mobile devices also can be capable of nonverbal communication employing cyber characters/videos, robots are notable in their capacity for nonverbal communication, such as facial expressions, gestures and actions, while coexisting with users in a real environment such as the home/classroom. Additionally, robots are different from computers and mobile devices in a way that they have a friendly appearance and are successfully capable of keeping social relations. This article covers an overview of the subject and our current activities/findings in the interdisciplinary field of RALL in the English as a Foreign Language (EFL) classes and as a case study in the broader filed of Social Robotics in Iran

The sector affected by surplus or scarcity of water requires proper understanding of river and landscape system behavior, what is possible to be done to prevent potential damages and losses need skilled professionals, who are familiar also with the newest IT based hydroinformatic tools and technological achievements to find the best possible solutions. An extensive programs of Water Authorities in Romania and in Hungary have been running to provide flood risk maps in all the main river basins including also those which across the both countries. The obtained results will be contribute to the better understanding and general prediction of flooding on the major river systems and assist the governments to act (in real time and space) in accordance with contingency planning based on flood risk management plans, moreover future development plans of regions and cities will get a proper guidance and platforms for future feasibility studies. However Flood Directive implementation has been ongoing in Romania and Hungary, `bridging and direct trainings` for relevant sectors as it is planned in this project have not been provided and have not been planned for future in Romania and Hungary. Based on these needs in 2011 was initiated and organized an international cooperation project financed by the European Union with the theme: “Development of knowledge canters for life-long learning by involving of specialists and decision makers in flood risk management using advanced Hydroinformatic tools” [1].

In the last few years, many applications for mobile devices have been developed to support learning experiences both in formal and informal contexts. One of the main limits of these applications concerns the development of learning materials suitable for mobile learning contexts. In fact, learning content must be usually prepared in advance by teachers and maintained during the whole lifespan of the application. In this paper, we present MeLOD, a mobile learning environment, which exploits the huge amount of dataset in the Linked Open Data (LOD) cloud to overcome the previous issue, and provides contextualized and continuously updated information based on students’ location. The position of the student sent by the mobile device is used to interlink Geonames DBpedia and Europeana datasets to provide information about all the interesting cultural heritage sites close to the student. Moreover, students social activities like voting and commenting are used to enhance the knowledge base of the environment and to provide recommendations for next students’ visits.

The development of mobile technologies and wireless networks encourages more research on Mobile Learning. Reviewing irregular verbs on a bus or organizing a training schedule on a Smartphone is becoming more common today. Mobile learning complements and enhances existing learning systems. Its development has been slowed in the early 2000s by both technical limitations and lack of dedicated teaching models. This article focuses on educational issues and proposes a solution by adopting the Method for Engineering Learning Systems MISA. Our work aims to identify basic elements, key characteristics and dimensions for developing the appropriate content for mobility. These elements are the basis for customization of the MISA method. Indeed, the different steps of MISA are governed by operating principles which ensure greater consistency and flexibility. Taking into account the specifications of Mobile learning in the development of these principles, we can adapt MISA to design a mobile learning system.

The learning difficulties of the mathematical concept of fraction is a topic that has been studied by different mathematical educators, but still is a relevant topic today, because despite the proposals that have been made to improve learning, they have not been used for all teachers besides those few that are involved in the use of the technology. Besides that there is little educational software that is based on research and is validated to be taken to the classroom.

Actor-network theory represents a way to look at things, very different from traditional approaches. Convinced that actor-networks can provide an excellent mindset to deal with innovation in engineering education we present a concise background on the topic oriented to this knowledge area. We deal with knowledge, learning, contexts, and actor networking within situated cooperative environments. We deal with the articulation of planned approaches and policies, providing ideas to explore contexts in which we can improve people’s involvement and design some innovative strategies and artifacts. We address the conciliation of sensibilities that normally wouldn’t be able to cooperate. We try to imagine a space of translations and negotiations that facilitate the formulation of problems as a combination of detours and extensions, constructing alignments to a goal

This article is derived from the research project and developed at School of Computer Sciences of the National Polytechnic Institute of Mexico. The article reports on the problems found among engineering students with respect to their resistance to using different representation registers when solving optimization problems in the Calculus Learning Unit. Use of such registers could help the students to build mathematics knowledge and to solve calculus problems. As a didactic strategy, simulations are used in an electronic environment in order to support the students by fostering their use of tabular, graphical and algebraic representation registers. Interviews are undertaken of six of the professors who gave the calculus courses, and a diagnostic questionnaire was applied to 68 students prior to and after working with the proposal. As for the theoretical framework, the work reported by Duval and Hitt is salient in this report, particularly their emphasis of the fact that working on activities by way of one single representation system is not sufficient. From the first responses provided by the students, one can conclude that the algebraic register is preferred by the majority of students. It is however used in a mechanical fashion without affording any meaning to the content of the problem and to the process of solving it. Another conclusion reported is that implementing tasks in the classroom in which the mathematics activity requires coherent use of different representations is necessary
