The area of unihabited aerial vehicles is receiving increasing attention with the associated technological advances in communication, computing and electronic infrastructure. Unihabited aerial vehicles are defined as aircraft without the on-board presence of pilot or aircrew. The role of humans is primarily on of supervisory control from remote locations. Issues such as systematic approaches to allocating functions between humans and automation, and coordination between remote operators and intelligent controls in the uninhabited vehicles under realistic scenarios are important problems. there is a need for an interactive modeling and simulator environment to support analysis of human/system issues in uninhabited air vehicles. This article describes Uninhabited Aerial Vehicles modeling and Analysis Simulator Testbed (UMAST), a web-based modeling and simulation architecture, useful to emulate characteristics of uninhabited aerial vehicles for studying human/system interaction. The architecture, implemented in Java, is extensible and facilitates concurrent, multi-user interactive simulations through a web browser with high-fidelity user interfaces. This paper outlines the architectural design, implementation, and application of UMAST in the context of a prototypical a military mission.

This study presents an interactive web-based approach for modeling rainfall-induced landslide susceptibility using Free Open Source Software (FOSS). The design is based on the R statistical framework and Shiny package coupled with the shallow slope stability model (SHALSTAB) from SAGA GIS. The easy-to-use real-time appli-cation extends the potential of current modeling efforts to non-expert R and GIS users and can also be used in an educational context for classroom teaching activity and enabling research-informed learning. The parsimonious approach (i.e. few parameter inputs) is accomplished in two sequential steps including modeling and validation by the use of site-specific datasets. The approach was tested in a case study on the Clearwater National Forest and the results from the validation showed an overall accuracy of 0.894, kappa of 0.789 and AUC from ROC curve was 0.715. The modeled landslide potential may be used as a decision-support tool for local planning.

This paper describes a study conducted in the context of chemistry education reforms in Israel. The study examined a new biochemistry learning unit that was developed to promote in-depth understanding of 3D structures and functions of proteins and nucleic acids. Our goal was to examine whether, and to what extent teaching and learning via model-based learning and animations of biomolecules affect students' chemical understanding. Applying the mixed methods research paradigm, pre- and post-questionnaires as well as class-observations were employed in the collection, analysis, and interpretation of data. The research population included 175 grade twelve students, divided into three research groups: (a) hands-on exploration of animations, (b) teacher's demonstrations of animations, (c) traditional learning using textbooks. Findings indicated that the integration of model-based learning and 3D animations enhanced students' understanding of proteins' structure and function and their ability to transfer across different levels of chemistry understanding. Findings also indicated that teachers' demonstrations of animations may enhance students' 'knowledge'aEuro"a low order thinking skill;however, in order to enhance higher levels of thinking, students should be able to explore 3D animations on their own. Applying constructivist and interpretative analysis of the data, three themes were raised, corresponding to cognitive, affective, and social aspects of learning while exploring web-based models and animations.
