Traditional works of public goods game focus on the situation that agents play the games in simplex networks in which social interactions are of the same type. However, due to multiple types of interactions in reality, agents always have to allocate the limited resources according to different interactions, such as the agents allocate the limited time to work with colleagues or accompany family members...
The network distance education is a new form of further education based on computer information technology, its advantages lie in breaking the limits of time and space, besides stimulating students the initiative of learning. However, it influenced by traditional academic education, so the advantages of the above model don't get fully exerted. The text analyzes from these above problems, it based...
This paper discusses the recommender models and methods for crowd sourcing platforms. These models are based on modern methods of data analysis of object-attribute data, such as Formal Concept Analysis and biclustering. In particular, the paper is focused on the solution of two tasks - idea and antagonists recommendation - on the example of crowd sourcing platform Witology.
The task of tracing what underlies the transition from kinship tribes to nation states continues to remain an important challenge for interdisciplinary study. Multi-agent simulation can shed light on these evolutionary processes by examining the emergent social behaviour that arises from individual agent interactions. In this paper, we build a model based on existing observational and simulation studies...
Enterprise knowledge cooperation network is established as an integration of knowledge nodes and cooperation connection links among those nodes. The nodes represent knowledge used in enterprise business process. The links represent cooperation connections based on analysis of business time-sequence relation. Gantt chart is applied to describe the time-sequence relation of knowledge nodes during their...
While common task models in real-time analysis assume a task as being activated by a single event and producing a single outgoing event after its full completion, the event dependency analysis extended the model to allow for multiple outgoing events to occur already during the run-time of a single job. It uses the structure of a timing-annotated control flow graph to calculate the maximal densities...
IT has changed business model and business process, and has become an essential ingredient for the competitive advantage. Under such circumstances, a conventional requirements engineering methodology is not sufficient. We propose an IT-driven business model design methodology in order to take advantage of innovative information technologies. The proposed methodology includes XBMC (eXtended BMC), an...
This paper proposed an optimization algorithm based on information flow testability modeling to optimize the selection of TPs. This method is an improved particle swarm intelligence algorithm based on the traditional fuzzy particle swarm algorithm. And improvements were made according to the features of dependence matrix. Software simulation was made to proof this methods.
As a newly popularized online social network, micro-blog has been facilitating numerous social interactions and communications in our daily life. Websites serving as micro-blog share certain characteristics of scale-free network with a fractal dimension macroscopically, and a faster spread of information has emerged by the hand of the least entropy generation principle through this complex system...
A combined method based on grey relational analysis and entropy method was used to propose an evaluation model for organizational health, in which the entropy method was introduced to determine the weight of each indicator for organizational health, and the grey relational analysis method was introduced to evaluate and rank the degree of health for each organization. Then we used the evaluation model...
Free vibration analysis of a double-walled carbon nanotube (DWCNT) is performed where the surrounding medium has been modeled employing a Winkler model. The nonlinear differential equation of motion is derived for both layers of the nanotube by using an analytical method. In order to solve the coupled nonlinear differential equations of the system, the variational iteration method is utilized. By...
This paper shows efficacy of an algorithm detecting man-made objects area by measuring and analyzing wave scattering from its models. The algorithm uses the co-polarized correlation coefficient in LR circularization basis and its normalized one, and switch these coefficients for detecting the man-made objects not only normally but also obliquely alignment to the radar illumination direction. For setting...
To provide seamless Source mobility support in the NDN (Named Data Networking) architecture, we propose a Proxy Based Mobility support Approach, dubbed PBMA. In this approach, we deploy a Proxy to maintain the mobility status of the Source, and suppose the Proxy is continuously active in transmitting or caching Interest packets in the person of the Source. For that, we assign a layered ID to each...
Behavioral scientists have historically relied on static modeling methodologies. The rise in mobile and wearable sensors has made intensive longitudinal data (ILD) — behavioral data measured frequently over time — increasingly available. Consequently, analytical frameworks are emerging that seek to reliably quantify dynamics reflected in these data. Employing an input-output perspective, dynamical...
The dynamic performance requirements of the developed school bus was introduced. The forward-facing vehicle simulation model was established and used to simulate four powertrain configurations in three driving cycles. Simulation results shows merits and faults of four powertrain configurations in dynamic performance, all-electric range, fuel consumption and electricity consumption. A series plug-in...
Effective planning is the key management function of any enterprise. Planning is the process of determining organizational aims, developing actions in condition of the current environment, selecting the course of action, initiating activities required to transform plans into action, and evaluating the outcome. Planning is possible at various levels of detail actions: strategic, tactical and operational...
Secure communication in Wireless Sensor Networks (WSN) is usually based on symmetric cryptographic approaches, whose robustness relies on an efficient key management protocol. Most of the reported key management protocols follow either a centralized approach where a single node has the authority of distributing the global shared key, or a partially collaborative approach where key distribution is...
Study on energy consumption in wireless systems becomes attractive recently. The worldwide organization 3GPP has established a series of standards to help reduce energy consumption in wireless systems. However, the utilization of green related techniques is still in theoretical way. To reduce energy consumption in cellular networks, the effective and common method is to shut down idle base stations...
A novel permanent-magnet (PM) linear motor which composes of two isolated movers and one single stator is proposed in this paper. It is suitable for tasks requiring multiple drive motors. Each mover can produce independent force and flexible motions by interacting with the stator poles. Compared with conventional multi-motor driven system, it achieves more compact size, and thus increases the system...
To improve the BDS positioning precision, the model of the BDS static positioning errors is presented by using time series analysis. The error series is verified to be non-stationary, so the non-stationary components, including the trend component and the periodic component, should firstly be extracted, and then we can build an AR (2) model to fit the residual stationary random component, parameters...
