We are developing online interactive materials that allow students to adapt their text and homework to their own needs and interests. For example, students may specify topic areas of interest and then selected mathematics homework word problems are adapted to those areas. Using proper data management, their work can be hand-graded with feedback for the students and allowances for students to correct...
In the ever growing literature on countering the cyber threat, the so-called JDL model of data fusion, well established in the information fusion community, has been applied to characterize the inner structure of problems within cyber defence and their mutual relationship. The overarching goal is to provide contributions to comprehensive cyber situational awareness by producing timely situation pictures...
Communication in online social networks has been analyzed for some time regarding the expression of sentiments. So far, very little is known about the relationship between sentiments and network emergence, dissemination patterns and possible differences between positive and negative sentiments. The dissemination patterns analyzed in this study consist of network motifs based on triples of actors and...
The Command and Control (C2) system that provide information to the actors in a conflict has always been a key target for technology advancement. The ongoing development of automated digital military information systems has enabled, and is demanding the development of specific functional area support systems. The focus of communication systems and methods is shifting away from human to human communication...
To investigate the influence of information about fellow group members in a constrained decision-making context, we develop four two-armed bandit tasks in which subjects freely select one of two options ( or ) and are informed of the resulting reward following each choice. Rewards are determined by the fraction of past choices by two functions (unknown to the subject) which...
The focus of the work in this paper is a systems-theoretic construction, analysis, and evaluation of a deterministic model of human decision making relative to experimental data. In sequential two-alternative forced choice decision tasks, a human subject is presented with two choices at every time step, is given finite time to select one of the choices, and receives a reward after a choice is made...
Due to the complex and relatively unpredictable nature of human behavior, customer service-based processes such as those featured in call centers, restaurants, and hotels can be challenging to model. The present study provides an example of using established theories of customer behavior, in combination with primary data collection, in a time and cost efficient way to model customer decision-making...
In recent years scientific workflows have been used for conducting data-intensive and long running simulations. Such simulation workflows have processed and produced different types of data whose quality has a strong influence on the final outcome of simulations. Therefore being able to monitor and analyze quality of this data during workflow execution is of paramount importance, as detection of quality...
This paper presents an empirical study of the learning organisation culture in Malaysian manufacturing companies. A survey, called the Dimensions of Learning Organisation Questionnaire (DLOQ), was used to collect data from employees of selected manufacturing companies. The data were analysed to assess the reliability and validity of the score of the DLOQ. The data were also analysed to determine the...
Engineering for the development, application, and recycling of products is recently supported by fully integrated model of product. Prototyping is moving to virtual by the application of sophisticated product models for complex simulations. Simulations rely upon knowledge representing experience, expertise and intelligence of engineers in knowledge wares. Increasing proportion of this knowledge is...
Competency Definition data objects are used to specify competencies, skills and learning objectives in a Learning Management System and in Competency Profiles. This paper presents the main standardization works in this area, covering specifications like the IEEE Reusable Competency Definition, the IMS Reusable Definition of Competency or Educational Objective and the outcomes from official standardization...
Humans make decisions on the basis of their situation awareness and it is well-known that insufficient situation awareness leads to incorrect decisions. The challenge of an advanced surveillance system for supporting situation awareness of a human decision maker is therefore to detect and assess complex situations that evolve over time. In this article, we present a conceptual framework for automatic...
In this paper, we propose a software prototype to simulate the human behavior in a domestic space. Our simulation takes into consideration the household structure and data about its residents lifestyle. The proposed system uses a multi-thread architecture, for each household's resident we deploy a single thread. The household resources management is based on the constraints propagation. We develop...
This paper presents an extension to the Rule-Based Similarity (RBS) model a novel rough set approach to the problem of learning a similarity relation from data. The original model, proposed in [1], applied the notion of Tversky's feature contrast model in a rough set framework to facilitate an accurate case-based classification. In the dynamic RBS model, a dynamic reducts technique is used to broaden...
Reduction techniques are important tools in machine learning and pattern recognition. In this article, we demonstrate how a kernel-based density estimator can be used as a tool for understanding human category representation. Despite the dominance of exemplar models of categorization, there is still ambiguity about the number of exemplars stored in memory. Here, we illustrate that by omitting exemplars...

During the recent years, a great change in engineering was replacing the conventional CAD/CAM/CAE systems with highly integrated product lifecycle management (PLM) systems. Earlier concentrations on specific fields of engineering replaced by a product concentration where an integrated product model has capability to accommodate all information needed during the lifecycle of the product from the first...
During the past decade, engineering moved into virtual spaces in the leading industries and product model became a medium between communicating engineers. This change motivated the authors of this paper to make a development on currently prevailing product representations where human intent, engineering objective are not included in product models. Lack of this decision background information makes...
Engineering requires vast amount of highly related information about products, production environments, application environments, etc. at development, production, application, and recycling of products in advanced computer systems. During lifecycle of product, engineers and other humans have influence on product information according to their role within a project team or outside of it. Short innovation...
Poor communication between engineer and engineer controlled product model data generation procedure has become a critical concern in virtual space based product development. Engineer does not able to communicate elements of thinking process at decision making on engineering objects and their relationships simply because current product modeling is not suitable for this purpose. This classical style...
