In this article we consider a certain sub class of Integer Equal Flow problem, which are known NP hard. Currently there exist no direct solutions for the same. It is a common problem in various inventory management systems. Here we discuss a local minima solution which uses projection of the convexspaces to resolve the equal flows and turn the problem into a known linear integer programming or constraint satisfaction problem which have reasonable known solutions and can be effectively solved using simplex or other standard optimization strategies

The analysis of literary works has experienced a surge in computer-assisted processing. To obtain insights into the community structures and social interactions portrayed in novels the creation of social networks from novels has gained popularity. Many methods rely on identifying named entities and relations for the construction of these networks, but many of these tools are not specifically created for the literary domain. Furthermore, many of the studies on information extraction from literature typically focus on 19th century source material. Because of this, it is unclear if these techniques are as suitable to modern-day science fiction and fantasy literature as they are to those 19th century classics. We present a study to compare classic literature to modern literature in terms of performance of natural language processing tools for the automatic extraction of social networks as well as their network structure. We find that there are no significant differences between the two sets of novels but that both are subject to a high amount of variance. Furthermore, we identify several issues that complicate named entity recognition in modern novels and we present methods to remedy these.

This GI-Dagstuhl seminar addressed the problem of visualizing performance-related data of systems and the software that they run. Due to the scale of performance-related data and the open-ended nature of analyzing it, visualization is often the only feasible way to comprehend, improve, and debug the performance behaviour of systems. The rise of cloud and big data systems, and the rapidly growing scale of the performance-related data that they generate, have led to an increased need for visualization of such data. However, the research communities behind data visualization, performance engineering, and high-performance computing are largely disjunct. The goal of this seminar was to bring together young researchers from these research areas to identify cross-community collaboration and to set the path for long-lasting collaborations towards rich and effective visualizations of performance-related data.

Background: This paper reports the results of an evaluation of the Software Sustainability Institute’s Fellowship Programme, which focused on identifying and categorising the benefits that the fellowship has afforded its recipients, via a series of open questions. Methods: The evaluation took the form of a survey open to people awarded Fellowships between 2012 and 2016, which asked people to report the effect that the programme had had on them, their institutions, their research domains and their careers. Results: The results show that the Fellowship plays a wide-ranging role in supporting communities of best practice and skills transfer, and that a significant benefit is the way it has raised the profile of software in research, and those people who develop and advocate for it. Conclusions: The evaluation of the programme has shown the need to support research software in situ and credit the engineers and researchers who are working in this important area that supports reproducibility, reuse and the integrity of research investments.

According to predictions bases on a climate-driven large-scale model the areas surrounding Lake Léman and, to some extent, the Swiss Plateau are suitable for the spread of Ae. albopictus North of the Alps, while other areas in Switzerland (e.g., the city of Zürich) seem currently too cold in winter for the survival of eggs. However, this model does not take into account particular micro-climate conditions in urban areas where the specie thrives. Climate conditions in urban micro-habitats (in particular catch basins) increase the probability of the survival of diapausing eggs in the winter season favoring the colonization of new cities that were thought to be too cold for the survival of the eggs. Therefore, there is an urgent need for appropriate monitoring tools and risk-based surveillance of Ae. albopictus populations. In 2018 a multidisciplinary group of researchers from the University of Applied Sciences and Arts of Southern Switzerland (SUPSI) has joined launching the project ALBIS (Albopictus Integrated System). The designed system focuses on the monitoring of urban catch basins, primarily on micro-climate environmental sensing, data transmission, data acquisition and data dissemination. The gathered data are the input for an empirical machine learning model for the prediction of spatial and temporal distribution of the Ae. albopictus. The first real time monitoring tests are in progress in the pilot area in the city of Lugano in the Canton Ticino. Fully functional prototypes have been engineered by the Institute of Earth Science in collaboration with a local electronics manufacturer (TECinvent) combined with the Open Source istSOS OGC Sensor Observation Service software for data acquisition and dissemination, and in the first tests cases have demonstrated good quality in terms of energy efficiency, data quality and data transmission reliability. The first results demonstrated that temperature in catch basins can be different from outside temperature that is detected by traditional terrain measures: in February 2018 during a period of cold air temperature in Canton Ticino of down to -8°C, the prototype sensor monitoring the catch basins' wall surface shows temperatures up to 6°C higher. Considering that one of the Ae. albopictus establishment thresholds is to have a mean January temperature of >0°C to allow egg overwintering, taking into account this micro-climate environments could lead to more realistic predictions.

In a digital world in the making, digital natives develop new learning profiles, interests, and way of working. Simultaneously teachers are facing students with lack of engagement and motivation with quite traditional learning process that has probably to be reframed considering the effects of digital transformation in the education sector. This issue is acute when it comes to complex subject of study, such as SQL geospatial to manipulate the geospatial characteristic of data. Indeed, some common difficulties have been identified by teachers from HEIG-VD university both in Media Engineering and Geomatics fields of study. The user-centered approach aims at creating digital products highly responding to the user’s needs through techniques improving the user experience. Various aspects have to be considered, including emotions. In education, gamification, along with user experience, interface design and usability best practices is one promising approach able to increase the learner's engagement, interest and motivation. It aims to implement game mechanics within non-game context, in order to motivate the learner to accomplish a task and increase the ability to learn new skills. Using a gamification layer within a given context, being digital or not, act as a motivational trigger. It helps giving meaningful, enjoyable and empowering experience. SQL Island is a project from Kaiserslautern University of Technology which illustrates very well a gamified learning experience of the SQL special-purpose programming language. The GeoSQL Journey project goes further, tackling SQL geospatial to learn in a fun way how to manipulate the geospatial characteristic of data. It is a gamified pedagogical application to introduce the students to the practice of SQL geospatial during the first hours or days of the course. Serving as an initiation, it is designed to focus on intrinsic motivation (personal development, quest, challenge and fulfillment) with learning objectives determined and integrated with an engaging and coherent game world and narrative. This paper describes the early work of conceptual design of the GeoSQL Journey project. Game mechanics and game interface has been conceived and brought together according to the literature in the domain and best practices on this matter. The following step for this project is to elaborate a testing method without yet having to develop an application prototype (e.g. organizing a fairly raw tabletop game associated with a classic SQL console) so as to challenge the design with students and teachers to get their feedbacks. Also, it is envisioned to evaluate how existing open source gamification tools and frameworks would be suitable to develop the first prototype planned for the 2019-2020 academic year.

This paper presents the design, realization and evaluation of a Map Design course conducted using an open source GIS (QGIS) to students of the bachelor in Visual Communication. The specific challenge was teaching approaches from Social Science and Humanities (SSH) and Science, Technology, Engineering and Mathematics (STEM) disciplines to integrate rigorous cartographic methodologies for map production with aesthetic visual aspects. This was successfully addressed with an hybridization approach that discuss themes from the two disciplines point of view and a goal-oriented course organization that produced as an output real map products. The general evaluation of this new course by students and teachers was positive. Despite the main criticism was related to the complexity of the used tools with respect to the course duration, the quality of the outputs demonstrated a very good capacity of students in learning and fusing of STEM and SSH concepts.

GeoWall is an innovative interactive physical wall based on advanced Open technologies that enables the dissemination of scientific contents to a wide public. The system, in line with Open Science principles, aims to promote the link between science, local impacts, education and global context so that the intrinsic value of university is clearly communicated and understood to citizens. GeoWall is though to be an interactive panel that combines touch technology, web services, visualization on maps, multimedia contents and digital graphics in a lightweight kinetic structure realized with digital manufacturing techniques. In the front a touch screen and multiple moving screens will display the information while in the back a panel worked with the numeric control milling machine will represents the scientific data element. The system is designed to use open technologies as much as possible including Open Software and Open Hardware. The touch screen enables user interaction by selecting global challenges and local impacts represented on a dynamic map. When interaction is activated additional information is communicated trough smaller moving screens representing different multimedia sources and formats. Although the system is not yet completed, the first tests are very promising and already give clear indications on the appropriateness of the selected concept and realized hardware and software.

This paper describes a method that uses georeferenced landscape pictures extracted from open picture collections for the determination of the population's interest in spatial features. The automated method takes into account the coordinates of the camera position as well as the azimuth angle, the focal length and the crop factor in order to calculate a field of view using a digital terrain model (DTM). This field of view can thereafter be used for the determination of interest in spatial features. In a case study involving more than 3'000 georeferenced pictures we investigate the potential of the method.

In a case study involving more than 3'000 georeferenced pictures we investigate the potential of the method.","PeriodicalId":93040,"journal":{"name":"PeerJ preprints","volume":"13 1","pages":"e27234"},"PeriodicalIF":0.0,"publicationDate":"2018-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88914037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
