Abstract: The US Department of Defense, including the Army, Air Force, Navy, and Defense Advanced Research Projects Agency (DARPA) has engaged in cognitive enhancement research and development for over a century, exploring novel pharmaceutical, dietary, neuroscientific, instructional, technological, and sleep-related enhancement strategies. The overall objective of this work is to identify safe, reliable, and robust strategies and technologies to help military personnel achieve dominance through enhanced skill acquisition, vigilance and threat detection, situation awareness, decision-making, teamwork, and emotional control. The present review provides an introductory overview of recent and current US Army research examining several approaches to cognitive enhancement. These include approaches aimed at specifically targeting neural mechanisms and processes directly responsible for enhanced task performance and include transcranial electrical stimulation (tES), augmented reality (AR), and targeted skills training. Also considered are approaches targeting nth-order mechanisms and processes that relatively indirectly affect perception, cognition, and/or emotion and include nutritional and dietary intervention, resilience, cognitive and teamwork training, peripheral nerve stimulation, and sleep modification. We detail several promising approaches and provide an overview of forward-looking research objectives pursued by the US Army. Finally, we provide an overview of some of the ethical, regulatory, methodological, technological, doctrinal, and reliability challenges facing cognitive enhancement research and constraining its immediate application to military training and operations.

Abstract: Augmented Reality (AR) has been shown to enable several construction tasks and supplement the use of Building Information Modeling (BIM) on construction sites. However, little effort has been made to evaluate the effect of specific task attributes and model-related factors on the accuracy and performance of current generation AR devices. To address this knowledge gap, the authors identified a commonly used AR device and conducted an experiment related to electrical construction point layout tasks. Furthermore, the effects of several task attributes and content variations were explored. The results suggest that the AR device can display content with a locational accuracy of five centimeters from intended design, equally distributed along the X-axis and Y-axis on the design plane. The location of the content is more accurate the closer it is to the paper marker used to locate content in space. Additionally, increased amounts of content shown and variations in types of content displayed significantly affect the accuracy of the points along the Y-axis (elevation). This paper provides an empirical understanding of certain capabilities and limitations of current AR devices using industry practitioners. The research enables practitioners to better plan for the use of AR in different construction and engineering tasks, and guide future research to develop use cases around the strengths of the technology.

Abstract: The purpose of this research is to determine the effect of course material developed with augmented reality (AR) technology in teaching subjects related to coding on students' academic achievement, their level of permanence in learning and their opinions on the process. The mixed method was used in the study. In the quantitative dimension of the research, semi-experimental design with pretest-posttest control group, and in qualitative dimension phenomenology pattern were preferred. The quantitative data of the research were collected with the achievement test and the qualitative data were collected with a semi-structured interview form. The study group consists of 64 students attending a university in Computer Programming department in Turkey. There are 34 students in the experimental group and 30 students in the control group. The prepared achievement test was applied to the students as pretest, posttest and permanence test. After the application, interviews were made with 15 students selected from the experimental group. As a result of the research, it is seen that the academic achievement and permanence levels of students in the experimental group using AR course material for teaching coding education are higher than the students in the control group. According to the results obtained from the qualitative dimension of the research, it has been determined that AR technology provides many advantages such as efficiency, permanence, comprehensibility and convenience on learning; accordingly, it has been suggested that it should be expanded in different courses and fields.

Abstract: This study presents a model of a tool for spatial visualization of processes occurring in the stakeholder environment concerning relationship management according to the ISO standards for management systems. Spatial visualization is based on cartographic methodology extended with technological capabilities used in GIS (Geographic Information Systems) systems. Thanks to the method, different types of issues using environment maps can be presented. This paper proposes a model of a tool enabling multi-criteria spatial visualization of states, phenomena, processes and plans taking place in the discussed environment. The proposed model of visualization is to be used in the future to present the results of research in the discussed field. They concern stakeholder relationship management according to the ISO management systems. Appropriate technology is required for the application of the model. The study is part of a stream of works aimed at using the concept of space to describe various sections of reality. It may have both theoretical implications (visualizations based on spatial models), as well as practical ones related to popularizing the use of various types of space to describe phenomena and planning. The originality of this study is that the present model-based visualization features selected stakeholders within the ISO standards. As part of the visualization example, heuristic spaces were defined, on which objects representing different types of stakeholders were placed, their significance as part of the ISO standard being determined according to each of the features: power, interest and predictability. The data was obtained in a branch of an international corporation operating in the packaging industry.

Abstract: The 20th century brought about major social challenges related to civil and human rights, triggering changes in urban environments and gradually adjusting the spatial and functional performances of cities to the needs of all users. In this article, the concept of Universal Urban Design (i.e., “Design for All”) is regarded as a sustainable placemaking process which enables the higher accessibility and usability of cities for all people, regardless of their age or (dis)abilities. The pilot project “Creating Accessible Pedestrian Corridors by the Limitless GIS Application” conduced in Serbia from 2017 to 2019 by the Faculty of Architecture at the University of Belgrade and the Non-Governmental Organization (NGO) Limitless proposes an innovative approach to urban design. Based on information and communication technology (ICT) adaptation, it is focused on the alternative concept-design of buildings, provision of ICT-based infrastructure, socioeconomic integration of all users, and ultimately on overall urban sustainability. The main outcome of the project was the development of a Geographic Information System (GIS) android application and an e-platform for adaptive placemaking. The project also provides a set of accessibility criteria based on Universal Urban Design, criteria that enable the mapping of locations based on the type of use, a set of recommendations for identified problems, as well as a brief analysis of the latest technological solutions for overcoming detected physical barriers. The Limitless GIS android application differs from the existing ones since it primarily identifies two target groups: (1) people with disabilities who could upload necessary data by established criteria; and (2) employees in the public sector (city authorities and municipalities) in charge of planning alternative routes and setting priorities and investment costs based on the identified problems. Pilot results of the project have revealed that in the current Serbian practice, there is still a lack of planned, consistent and continuous movement routes in urban areas. Terrain configuration represents a serious limitation for people with disabilities, while lifting platforms are recognized as a better solution than ramps (both for paraplegics and quadriplegics), due to their higher efficiency and minimized spatial requirements. Therefore, the android application and e-platform presented in this article contribute to the detection of actual problems at the local level as well as to the overall improvement of planning/design practice in Serbian cities.

Abstract: The time required to recognize that two perspective drawings portray objects of the same three-dimensional shape is found to be (i) a linearly increasing function of the angular difference in the portrayed orientations of the two objects and (ii) no shorter for differences corresponding simply to a rigid rotation of one of the two-dimensional drawings in its own picture plane than for differences corresponding to a rotation of the three-dimensional object in depth.

Abstract: A method for identifying clusters of points in a multidimensional Euclidean space is described and its application to taxonomy considered. It reconciles, in a sense, two different approaches to the investigation of the spatial relationships between the points, viz., the agglomerative and the divisive methods. A graph, the shortest dendrite of Florek etal. (1951a), is constructed on a nearest neighbour basis and then divided into clusters by applying the criterion of minimum within cluster sum of squares. This procedure ensures an effective reduction of the number of possible splits. The method may be applied to a dichotomous division, but is perfectly suitable also for a global division into any number of clusters. An informal indicator of the "best number" of clusters is suggested. It is a"variance ratio criterion" giving some insight into the structure of the points. The method is illustrated by three examples, one of which is original. The results obtained by the dendrite method are compared with those...

Abstract: Directional data is ubiquitious in science. Due to its circular nature such data cannot be analyzed with commonly used statistical techniques. Despite the rapid development of specialized methods for directional statistics over the last fifty years, there is only little software available that makes such methods easy to use for practioners. Most importantly, one of the most commonly used programming languages in biosciences, MATLAB, is currently not supporting directional statistics. To remedy this situation, we have implemented the CircStat toolbox for MATLAB which provides methods for the descriptive and inferential statistical analysis of directional data. We cover the statistical background of the available methods and describe how to apply them to data. Finally, we analyze a dataset from neurophysiology to demonstrate the capabilities of the CircStat toolbox.
