Model deficiencies, despite their negative influences on assessment of modeling and simulation (M&S) applications, carry a large amount of insightful information, which can be used to measure different aspects of the M&S development process and its verification and validation (V&V). Although there already exist various categorizations of model deficiencies, none of which can be used as...
The accurate estimation of environment is a precursor to awareness of the situation around subject(s) of interest. It is imperative that awareness leads to better, improved and safer surroundings and in many cases averts disasters. Following clues from human cognitive nature there have been a significant progress in the development of situation awareness (SAW) models and its implementation in wide...
In this paper, a modelling and measurement technique for propagation of indoor wireless communication considering the building's structure and human bodies residing in the building is presented. First, an effective model for simulating and measuring electromagnetic waves propagating inside inhabited buildings was suggested. Next, electric field distribution were numerically analysed and compared with...
A Fuzzy Preference Framework for the Graph Model for Conflict Resolution is employed to analyze the sustainable development conflict in order to gain strategic insights. This framework is a novel methodology to identify outcomes favorable for all parties in a multiple-participant multiple-objective decision making setting with both certain and uncertain preference information. When applied to the...
Methods that use the underlying (influencing, contributing, performance-shaping, etc.) factors in human operator error analysis, in general, inadequately incorporate them into the operator's model of erroneous action. This paper describes the method of error analysis in which the factors of the operator's performance and the underlying factors are considered to be coherent on all stages of the erroneous...
Breakdowns in complex systems often occur as a result of system elements interacting in ways unanticipated by analysts or designers. The use of task behavior as part of a larger, formal system model is potentially useful for analyzing such problems because it allows the ramifications of different human behaviors to be verified in relation to other aspects of the system. A component of task behavior...
We have observed increasing interest in visual analytics tools and their applications in investigative analysis. Despite the growing interest and substantial studies regarding the topic, understanding the major roadblocks of using such tools from novice users' perspectives is still limited. Therefore, we attempted to identify such “visual analytic roadblocks” for novice users in an investigative analysis...
Wireless networks growing popularity coupled with a wide availability of wireless-enabled personal devices is today the basis for user-centric Internet architectures to evolve. Central to this new paradigm of user-centricity is the fact that today the Internet end-user exhibits a highly nomadic behavior, where most of the portable devices are carried by humans. The thesis proposed relates to the recent...
Safety critical systems can suffer severe and even fatal consequences due to aberrant behavior of human operators. Human operators are unique in their decision making capability, judgment and nondeterminism. There is a need for analyzing the interactions among computer systems and human operators where the operators are allowed to deviate from their prescribed behaviors for executing a task. In this...
Human-automation interaction, including erroneous human behavior, is a factor in the failure of complex, safety-critical systems. This paper presents a method for automatically generating task analytic models encompassing both erroneous and normative human behavior from normative task models by manipulating modeled strategic knowledge. Resulting models can be automatically translated into larger formal...
Automated systems are increasingly complex, making it hard to design interfaces for human operators. Human-machine interaction (HMI) errors like automation surprises are more likely to appear and lead to system failures or accidents. In previous work, we studied the problem of generating system abstractions, called mental models, that facilitate system understanding while allowing proper control of...
This study builds upon previous work regarding people's attitudes toward robot workers, identifying the characteristics of occupations for which people believe robots are qualified and desired. This research updates prior research and adds a new dimension of respondent expertise in the domain of robotics (N=392, which includes 134 robotics experts and 258 non-experts). We deployed a web-based survey...
Threat trees are notable tools in the security analysis process called "threat modeling"'. The trees are used to identify how and under what condition threats can be realized, which will help proper estimation of risks and planning of countermeasures. However, it is difficult for an average analyst to construct adequate trees, because security expertise, particularly from an attacker's perspective,...
In this paper, a quantitative risk analysis (QRA) model incorporating human and organizational factor is presented by integrating Fault Tree (FT) with Bayesian Network (BN). FT is used to model the factors how to contribute to the final failures. BN extends the causal chain of basic events to potential human and organizational roots and provides a more precise quantitative links between the event...
Cold standby system is a typical system in reliability engineering which reflects the reliability logic in a wide range of engineering structures. For practical engineering multi-unit standby system with unreliable switch, logic simulation is established and generic simulation process is proposed by analyzing structure model, switch failure model and control mode model of different people. Finally,...
The analysis of sets of degraded documents, like historical ones, is error-prone and requires human help to achieve acceptable quality levels. However, human interaction raises 3 main issues when processing important amounts of pages: none of the user or the system should wait for work, information provided by a human operator should not be restricted to local isolated corrections, but rather produce...
In the new rural programming and construction advancement, it needs protecting the unique nature landscape of rural settlement, and probing into its evolvement and development medel. By analysis the status quo of traditional rural settelment and point out its existing problems afterward, expounding objective and significant of protecting and updating traditional rural settelment, then point out the...
The article to human role in the movie' Hollywood movies Avatar mechanical AMP modeling analysis and process of setting a model for the object of study, explore design idea of directors through reverse analysis and design concept and in accordance with the Director to set the background, respond to the challenge of mechanics theory on the basis of using 3DSMAX AMP of three — dimensional cartoon technology...
Through analyzing the characteristics of human daily behavior based on contact data of students in the real world, and combining the complex network theory, a student social contact networks model was proposed. The basic statistical distribution results show that the model has the property of small world network. The analysis of human contact process is helpful to identify the human behavior law.
Practical experience suggests that use and understanding of UML diagrams is greatly affected by the quality of their layout. However, existing experimental evidence for this effect is been weak and inconclusive. In this paper, we explore two explanations. Firstly, we observe that the visual qualities of diagrams are more prominent in earlier life cycle phases so that the impact of layout quality should...
