Augmented Reality (AR) technology has become increasingly popular due to its potential use in an indoor environment. AR technology enables virtual information, such as navigation instructions, to be merged into the actual environment via a mobile screen. Using an AR-based Indoor Navigation speeds uptime while also being interactive in searching for a particular building location. Every year when new semester students enrol in the university, some students will have difficulty finding a particular location on the campus. The most searched for building upon arrival at the university is the student halls of residence. While searching for it, students waste time asking others for information or looking for a nearby campus map. Therefore, this project investigates the requirements needed for an AR-based indoor navigation application to be applied within the student halls of residence and identifies technical issues through a small-scale prototype development within a small navigational area. Seventy-one students participated in the feasibility study by responding to a set of questionnaires related to the Student Residence AR indoor navigation application. At the same time, four users with and without previous experience with AR applications evaluated the prototype application. The results identified that the more the students have difficulty searching, the more they require additional time to reach their destination and seek help from others, an excellent reason to implement the Student Residence AR indoor navigation. In addition, the prototype evaluation results discussed issues related to arrow path confusion, distance accuracy, assistive guideline, and software development challenges in AR development that could be beneficial to future developers and researchers.

This paper presents small-scale low-speed maneuvering tests with an oceanographic research vessel and the comparison with mathematical model using the real time maneuvering simulator developed by the University of São Paulo (USP). The tests are intended to verify the behavior of the vessel and the mathematical model under transient and low speed tests. The small-scale tests were conducted in deep and shallow waters, with a depth-draft ratio equal to 1.28, in order to verify the simulator ability to represent the vessel maneuverability on both depth conditions. The hydrodynamic coefficients used in the simulator model were obtained by CFD calculations and wind tunnel model tests carried out for this vessel. Standard turning circle and accelerating turn maneuvers were used to compare the experimental and numerical results. A fair agreement was achieved for shallow and deep water. Some differences were observed mainly in the initial phase of the accelerating turn test.

Mobile Augmented Reality (MAR) Technology in combination with Interactive Storytelling (IS) enables the design of new kinds of technology enhanced learning and entertainment applications. The existing pedagogical research as well as the available Interactive Storytelling MAR (ISMAR) Serious Games are rather limited. This is mainly because of the difficulties of MAR applications development and the complexity of IS authoring. The paper works on the direction to improve this situation exploring the combination of a) rapid prototype development methodology based on MAR authoring tools and b) the definition of IS genres which could serve as templates and guide the ISMAR design. In the paper, key concepts are presented, existing successful examples of MAR Serious Games are analyzed in order to extract their narration genre features, available tools for MAR rapid authoring are introduced, and afterwards the design, development and first evaluation of a prototype ISMAR Serious Game is presented. The paper contributes to the bridging of learning design, IS, and AR technology research communities and facilitates feature interdisciplinary research.

Many parts of the western US is rural in nature and consequently do not have electrical distribution lines in many parts of farms and ranches. Distribution line extension costs can run from $15,000 to $25,000 per mile, thereby making availability of electricity to small water pumping projects economically unattractive. Solar photo-voltaic (PV) powered water pumping is more cost effective in these small scale applications. Many western states including Wyoming are passing through fifth year of drought with the consequent shortages of water for many applications. Wyoming State Climatologist is predicting a possible 5–10 years of drought. Drought impacts the surface water right away, while it takes much longer to impact the underground aquifers. To mitigate the effect on the livestock and wildlife, Wyoming Governor Dave Freudenthal initiated a solar water pumping initiative in cooperation with the University of Wyoming, County Conservation Districts, Rural Electric Cooperatives, and ranching organizations. Solar water pumping has several advantages over traditional systems; for example, diesel or propane engines require not only expensive fuels, they also create noise and air pollution in many remote pristine areas. Solar systems are environment friendly, low maintenance and have no fuel cost. In this paper the design, installation and performance monitoring of the solar system for small scale remote water pumping will be presented.

<p><strong>Abstract.</strong> The identification of geographical phenomena and relations between them are most frequently visualized, analyzed and interpreted indoor by the display screen. The difficulties with capturing basic spatial relations significant in the process of teaching cartography become the main problem. The objective of teachers from the Department of Cartography and Geomatics was to enrich typical classes carried out in computer rooms by adding the outdoor academic classes that would encourage students to observe those relations directly in the field. In October 2018 the outdoor station of the area of 15&amp;thinsp;&amp;times;&amp;thinsp;20&amp;thinsp;m by the university campus next to <i>Collegium Geographicum</i> was handed over to the disposal of students. The projects of the elements of the station were created on the basis of the lecturers experience as a part of subjects on the following courses: topographical cartography, survey techniques, cartographic design, virtual and augmented reality in cartography, geovisualization and geomatics. Sets of several constructions that can be used either separately, as tools for explaining specific principles or together, as instruments for teaching subsequent measurement, location and visualization relations occurring in cartography and geomatics, were placed on the premises of the station.</p><p>In order to study historical ways of marking borders, the erratic, a replica of the boundary stone from 1653 with the triangle engraved in the place in which three countries connect, was placed in the field. Contemporary ways of the stabilization of the border points and points of the grid reference are farther located. The point marked on the metal horizontal plate, on the spot in which the meridian and the parallel of latitude cross, inform about multiple ways of recording the exact location in space. The values of coordinates were calculated for that point and engraved on the board in several nation and global reference systems. Students, standing on other three plates with the points marked where meridians cross parallels of latitude, create basic elements of the grid of latitude and longitude of 0.2''.</p><p>On a single plate three directions of the north, i.e. the geographic, topographic and magnetic one, are visible. One of the meridians marks the line of analemmatic sundial to 12:00&amp;thinsp;a.m. and the student standing on the area of the specific month becomes a gnomon whose shadow indicates the hour of the local meridian. Two surveyor's levelling rods with two values differing by approximately 16&amp;thinsp;cm demonstrate different values of contour lines on topographic maps worked out in Poland. Properly oriented topographic table shows the same fragment of space in four ways: on the classic, north-oriented topographic map, on the orthophotomap at 1&amp;thinsp;:&amp;thinsp;10&amp;thinsp;000 scale, on the simplified visualization of a few layers from the national topographic base at enlarged 1&amp;thinsp;:&amp;thinsp;2&amp;thinsp;000 scale and on the 3D printout on which the height of buildings was determined from the attribute table.</p><p>Authors of the Academic Outdoor Station in Poznan prepared for the conference guests the multimedia presentation with the explanations of the aforementioned constructions and other elements, i.e. the wall of cartographic visualizations with perspective and optical illusions presented on 2D boards, virtual and augmented reality table, triangular signal, and others. We hope to receive feedback from cartographers and hear some ideas concerning new constructions for our station.</p>

The Ecosystem Approach to Fisheries (EAF) management, recognising complexity, aims for the holistic, sustainable management of fisheries to promote healthy marine ecosystems and sustainable livelihoods. Effective implementation of the EAF has been problematic as we continue to grapple with issues of scale, knowledge integration and meaningful stakeholder engagement. Scenario-planning approaches in marine social ecological systems (SES) can address some of these challenges. Using systems-thinking, scenario-planning presents the opportunity to address challenges simultaneously at different scales of interaction by addressing the needs at smaller and larger decision-making scales. We here present a prototype scenario-based approach in which we used structured decision-making tools (SDMTs) in an iterative and interactive research process with marginalised stakeholders in a small-scale fishery in South Africa’s southern Cape. Using this approach presented an opportunity for fishers to consider pathways for future responses to change while enhancing personal and local adaptive capacity. At the same time, these marginalised fishers were provided with an important opportunity to freely air their views while engaging with tools new to them. The process did not only benefit fishers, but also provided valuable insights into how they view and experience their marine SES. The use of these tools has provided a means to integrate different knowledge streams, identifying ways in which challenges presented by scale in SES is better addressed. As a next step in the prototype development, expansion to more diverse stakeholders in the biogeographical region relevant for this fishery is recommended. We highlight how this approach can contribute to multi-level governance. When considering EAF implementation, we highlight how engaging marginalised stakeholders need not mean losing the reproducible, transparent processes required for modern management. Lastly, we discuss how multi-scalar flow of information could improve the implementation of an EAF in a developing society, such as that of South Africa.

Mobile Ict

The study is aimed at theoretical substantiation, development and experimental testing of methods of applying mobile technologies by university students. The objectives of the study imply adapting mobile testing systems and mobile means of multimedia development for using in the classroom environment at universities. The research object is application of mobile ICT to the educational process. The research subject is methods of applying mobile testing systems and mobile means to conduct practical classes at the University. The studies of Ukrainian and foreign researchers dedicated to the question of using mobile ICT for the university educational process were analyzed. Mobile testing systems are defined as a variety of mobile software support aimed firstly to measure students’ academic results, which enables to automatize the process of both current and final control through applying modern testing means, and secondly to intensify the educational process comprehensively. It is found that mobile means of multimedia development are to fulfill the principles of multimedia, space vicinity, time contiguity, coherence, modality, excessiveness, personalization, interactivity signalization and individual distinctions. The authors have developed the methods of applying mobile testing systems by taking Plickers system, as the one providing the opportunity to arrange a rapid feedback between a lecturer and both an academic group and an individual student. The system also allows conducting mobile surveys, in- class general questioning and instant control of students’ attendance. The authors have developed methods of applying mobile tools of multimedia development through using augmented reality. The comparative assessment of functionality of mobile testing systems and mobile means of developing augmented reality multimedia was held. Efficiency of the developed technology was experimentally tested and confirmed.

Due to the undesirable effects of the gap between citizens to access and use information and communication technologies (ICT), most researchers have been paying much attention to the threat of a digital divide. Unfortunately an amazingly large number of people do not have the abilities to use the ICTs in a proper way and, therefore, cannot draw advantages from its usage. As a result, digital divide is commonly regarded as a potential barrier for participation in the information society. This study measure the digital divide in Saudi Arabia by analyzing the results of a small-scale study conducted at the University KAU, regarding students’ and university members’ perceptions toward the usage of ICT. This analysis measure the digital divide concerning some factors like gender, educational level using a questionnaire. The analysis shows that KAU has no digital divide. Key words: digital divide, information and communications technology, ICT, diffusion of technology, second order effects.

Small Scale Irrigation

AbstractSmall-scale irrigation schemes (SSIS) have been considered a solution to viability challenges in drought-stricken farming areas in developing countries. However, the schemes face severe constraints. In this paper, relevant constraints are identified and ranked in terms of how serious the limitations are from the perspective of stakeholders in drought-prone areas of the Chipinge District in Zimbabwe. Information for the study was gained through a questionnaire and focus group discussions with small-scale irrigation farmers as well as key informant interviews with government irrigation officials, irrigation managers and members of the local community leadership. The information was garnered between August and December in 2017 with the analysis conducted using descriptive statistics and thematic analysis, guided by the Theory of Constraints and classified in the political, economic, social, technological, environmental and legal (PESTEL) framework. Results indicated that SSIS are important in the drought-prone areas of the Chipinge District regarding food security and income generation. However, technical issues bedevilling the schemes are considered to be the most challenging limitations. The most important constraints—ranked in descending order of gravity—are technical, economic, social, environmental, legal and political challenges. Based on these findings, the research strongly recommends modernising small-scale irrigation schemes’ infrastructure, among other issues, as a priority in Zimbabwe's drought-prone areas.
