Here we report findings from experiments that examine the efficacy of adding temperature information to the multimodal complex known to be of benefit in simulations. In the first experiment, Peltier tiles added thermal information to the kinesthetic feedback given by a hand-worn exoskeletal device and this increased ratings for 'presence' during interactions with simulated objects. In an experiment in which exploratory movements across surfaces of differing temperatures were either active or passive-guided, the degree of 'coldness' felt at the fingertip was reported as less intense when movement was active, suggesting that intentionality of movement plays a role in the attenuation of the thermal stimulus. Other work reported here suggests that the perception of temperature is not influenced by a simultaneously presented colour. For example, the perception of coldness is not enhanced when it is processed in conjunction with a blue colour. We discuss the potential value of thermal information within the context of the hypothesis that presence in simulated environments is enhanced by multisensory inputs that include redundant information.","PeriodicalId":311979,"journal":{"name":"Int.

A major challenge with such operations is the sheer size of the area to patrol. One way to address this problem is by noting that pirates are more likely to operate under favourable environmental conditions and to focus patrols in areas where such conditions prevail by generating maps of piracy risk based on environmental forecast. This contribution presents a system that invokes a multi-objective optimiser with each new forecast to help the decision makers plan operations over the course of days, weeks or months. Implemented using web-based technologies to mitigate for potential resource limitations at the client site, the resulting decision support system is demonstrated for a counter-piracy operation conducted off the coast of Somalia.","PeriodicalId":311979,"journal":{"name":"Int.

The stability analysis with a deterministic mathematical model based on differential equation yields the proper range of the parameters. A roadmap of connected cities, where the shortest path between a source-destination pair is to be determined, is taken as a problem environment. Exhaustive simulations confirm that the proposed deposition rule, with properly chosen parameter values, outperforms the traditional one with large margin both in terms of solution quality and algorithm convergence.","PeriodicalId":311979,"journal":{"name":"Int.

The efforts have been two folded, where the first effort was two NATO groups having an experiment demonstrating interoperability between the UGVs and OCUs available within the group. The Belgium contribution is done in the EU project ICARUS. Both efforts used the Joint Architecture for Unmanned Systems (JAUS) with the interoperability profile (IOP) to successfully enable interoperability between the systems. The trials showed that it is possible to extend the systems quite easily and achieve compliance with parts of the standard in a relatively short time.","PeriodicalId":311979,"journal":{"name":"Int.

Atop the uncertainty, ranking in the presence of multiple criteria, multiple agents, and heterogeneous sources of information is often the main task to accomplish by the analysts in the Intelligence Community (IC). Soft metrics are attributes of decision criteria that cannot be expressed numerically. These metrics are at the core of a computational engine that is perception-based, with computational 'atoms' expressed in natural language (NL). The soft metrics approach as a basis for natural language-based computing contributes to fast analyses and an efficient use of human resources in contemporary decision making such as: intelligence data analysis, the Global Strike (target pairing), risk analysis, threat assessment, strategic interactions, conflict analysis, and the strategic deterrence assessment.","PeriodicalId":311979,"journal":{"name":"Int.

Our schemes comprise of three steps. Firstly, MATLAB edge detection operator converts a grey scale image into a binary one. Our schemes are then applied on this binary image to detect closed loops. Finally, these closed loops are tested for different geometric shapes. The schemes with incredible time and memory efficiency can detect both intersecting and non intersecting regular shapes.","PeriodicalId":311979,"journal":{"name":"Int. J. Intell. Def.

Behavioural aspects range from those who create a plan to those who gather supplies for developing the devices to those who passively look the other way. Developing computational approaches to understanding such behaviour necessitates either a decomposition of behavioural activity into smaller, manageable behaviours or generalising larger, group behaviour where gross trends are observed. This may suffice for particular applications; however, additional consideration can be given to developing more comprehensive approaches. Specifically, for those seeking to understand terrorism, a number of social, cultural and behavioural perspectives are being developed by experts worldwide. These perspectives may complement each other or they may be in conflict, but they equally contribute to a broader understanding. Our research is developing computational methods to analyse and experiment with differing views and perspectives of potential influences on adversarial behaviour at this system-level.","PeriodicalId":311979,"journal":{"name":"Int.

An important objective is digital targeting focusing on target development and timely prosecution. The need to coordinate geographically distributed assets and personnel throughout a theatre of combat is constantly in tension with the need to prosecute quickly. This study provides an empirical comparison of digital targeting using baseline and potential future Command and Control (C2) systems as two experimental conditions. While CAGE IIIA demonstrated the benefits of a coalition human-in-the-loop experiment across multiple sites, we learned valuable lessons to improve this scientific endeavour. Technical failures and confounding factors have threatened the validity of this complex experiment, inevitably weakening our understanding of potential capabilities. For future work, we identify the need to consider the human dimension and extant processes for effective system integration.","PeriodicalId":311979,"journal":{"name":"Int. J. Intell. Def.
