Argumentation and trust models have been increasingly used in multi-agent systems research, with applications in several domains such as e-commerce. Negotiation is a form of interaction in which argumentation and trust can play a relevant role. Argumentation in a negotiation context has been defined as a way of interaction between trading parties that enables them to exchange information in order...
A major tenet of the US Army's data-to-decision initiative and a primary challenge for military commanders and their staff is the ability to shorten the cycle time from data gathering to decisions. Today, military operations require information from an unprecedented number of sources resulting in an unprecedented volume of collected data. Required are decision support technologies to improve the synthesis...
Changes in students' personal epistemology are especially important for engineering educators to examine because they may affect the way students learn and their ability to adapt to engineering education learning environments and culture. Despite the large amount of theoretical research that has been done concerning students' conceptual change, little research has been done concerning their epistemological...
On the base of simple emblematic example we analyze and explain the inconsistent and inadequate behavior of Dempster-Shafer's rule of combination as a valid method to combine sources of evidences. We identify the cause and the effect of the dictatorial power behavior of this rule and of its impossibility to manage the conflicts between the sources. For a comparison purpose, we present the respective...
Decision makers are required to make critical decisions throughout all stages of a life-cycle in large-scale projects. These decisions are important as they impact upon the outcome and the success of projects. In this paper we present an evidential reasoning framework to aid decision-makers in the decision making process. This approach utilizes the Dezert-Smarandache Theory (DSm) to fuse heterogeneous...
Self-organising systems have become important relatively recently. It is frequently claimed that their complex nature necessitates new formalisms to express and reason about them. In this paper the opposite view is taken. Following Back's use of action systems to express a distributed system as an initialised possibly nonterminating loop, here two simple but representative case studies of self-organising...
Standard complex system reliability computation is an important topic for system engineers. Current approaches for reliability analysis are fault tree analysis, true value table or minimal path sets. FTA can not solve many complex problems. This paper introduces the method of Bayesian networks for reliability estimation. The complex systems bayesian networks can be built by a new method. Using the...
In order to overcome the limitation of traditional maintenance support and adapt to the development of the maintenance support for armored equipment, this paper puts forward the idea of constructing a maintenance support system for armored equipment based on PHM technology, emphatically analyses the key technology of the system, such as data acquisition and sensor technology, data mining and information...
There is a lack of a neuroimaging biomarker for HIV-Associated Neurocognitive Disorder. We report magnetoencephalography (MEG) data from patients with HIV disease and risk-group appropriate controls that were collected to determine the MEG frequency profile during the resting state, and the stability of the profile over 24 weeks. 17 individuals (10 HIV+, 7 HIV−) completed detailed neurobehavioral...
With the rapid development of the information technology, it is inevitable that the distributed mobile computing will evolve to the pervasive computing gradually whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. To achieve this goal, one of the problems is how to continuously monitor/capture and interpret the...
The existence of self-serving bias in the customers' responsibility attribution of service outcomes in which they participate has never been empirically tested. As an important branch in service management, extant research on emotion management of service employees mainly draws on the theory of emotional contagion, but goes silent on how service employee's emotions affect customers' cognitive judgments...
This study aims to understand guests' perception of spa hotels relationships of brand cognition, service quality, leisure experience and repurchase intension. Survey system targeted on Miaoli County Tai District's most advanced spas, Tyan Hot Spring Resort, for the study area, and to the field to the Taian hot spring area hotel accommodations were targeted in the spring during peak season (December...
authentication of web service combination is the key to ensure the normal working of the combination service. Many methods of current web service combination are half-formalization, which can come out many errors and not easy to be detected, so the correctness is hard to be ensured. The paper introduces the Transfer matrix to analyze the deadlock problem in web service combination, and adopt Incidence...
Emerging technologies such as the Internet of Things generate huge amounts of network traffic and data which lead to significant challenges in a) ensuring availability of resources on-demand, b) recognizing emergent and abnormal behavior, and c) making effective decisions for efficient network operations. Network traffic data exhibit spatiotemporal patterns. Learning and maintaining the currently...
User attitudes are a major predictor of the endogenous variables in ICT adoption models. However it is known in the community that the predictive validity of user attitudes on behavioral intention to adopt ICT suffers from inconsistencies. Being a basic predictor of behavioral intention in models like TRA or TPB, user attitudes turned out not to be predictive of behavior in other studies [1]. Some...
Knowledge has become the most important source of competition in the knowledge era. Organizations establish knowledge teams with knowledge workers who have different specialties to accomplish specific tasks. Knowledge integration combines individual knowledge to achieve synergy and is important to knowledge teams. This study adopts a transactive memory perspective to understand if knowledge integration...
In this paper, we address the problem of merging argumentation systems (AS) in a multi-agent setting. Each agent's system may be built from different sets of arguments and/or different interactions between these arguments. The merging process must lead to solve conflicts between the agents and to identify ASs representing the knowledge of the group of agents. Previous work [6] has proposed a two-step...
Localisation has become a standard feature in many mobile applications. Numerous techniques for both indoor and outdoor location tracking are available today, providing a diversity of ways positioning information can be delivered to a mobile application (e.g., a location-based service). Such factors as the variation of precision over time and covered areas or the difference in quality and reliability...
Consumers' brand loyalty begins with brand cognition, so it has theoretical and practical significance to study the impact of brand recognition on brand loyalty. Based on literature searching, this paper divides brand cognition into brand association, brand image and perceived quality, builds conceptual model of impact of brand recognition on brand loyalty, and combines the model with the data. The...
This paper presents the modeling approach, methodologies, and initial results of setting up a multi-layer, hierarchical information management system (IMS) for the smart grid. The IMS allows its users to analyze the data collected by multiple control and communication networks to characterize the states of the smart grid. Abnormal, corrupted, or erroneous measurement data and outliers are detected...
