Modern mobile communication networks provide a variety of voice and data services. The latest set of mobile technology specifications by the 3rd Generation Partnership Project (3GPP) is referred to as Long Term Evolution (LTE). In this paper, the performance of a wireless network where LTE is used at the Medium Access Control (MAC) layer is evaluated. User Datagram Protocol (UDP) traffic is con...
Innovation occurs in network environments. Identifying the important players in the innovative process, namely “the innovators”, is key to understanding the process of innovation. Doing this requires flexible analysis tools tailored to work well with complex datasets generated within such environments. One such tool, cluster analysis, organizes a large data set into discrete groups based ...
In this paper the immune network system was presented by the sequence of species with new immunological components allowing more plausible to reflect the immune response processes. The mathematical model oriented to the describing of the more realistic immune processes in the dynamics allowed to organize the computational experiment in the first to demonstrate a possible very complex behavior i...
The crowdfunding industry is growing rapidly worldwide and poses new challenges on how to understand investment behavior. Indeed, a key challenge in this area is how to measure the similarity of an investor and a company, or the interest of an investor in a company. Tremendous effort has been made in previous research regarding the single effective factor or homogeneous network model based on l...
We address the problem of message transfer in a communication network. The network consists of nodes and links, with the nodes lying on a two-dimensional lattice. Each node has connections with its nearest neighbors, whereas some special nodes, which are designated as hubs, have connections to all the sites within a certain area of influence. The degree distribution for this network is bimodal ...
Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...
In this research, artificial neural network (ANN) and genetic algorithm (GA) were used in order to produce and develop the NiAl intermetallic coating with the best wear behavior and the most value of hardness. The effect of variations of current, voltage and gas flow on the hardness and wear resistance were optimized by ANN and GA. In the following, the optimum values of current, voltage and g...
In this study a modified entropy-based measure is presented for evaluating the serviceability level of water distribution networks in which the hydraulic uncertainties (flow rates in pipes) as well as the uncertainties due to mechanical parameters (failure probabilities of links) are considered simultaneously. In the proposed entropy calculation method, the connectivity order of the network dem...
Risks generally lead to Protecting Behavior. However, it is still unknown which specific Protecting Behavior results from Perceived Privacy Risk in Social Network Sites (SNSs). In this article, we draw from the Protection Motivation Theory to postulate an influence of Perceived Privacy Risk (Threat Appraisal) on six Privacy Protecting Behaviors SNS members can use, which we identified in the li...
We develop a minimal time-continuous model for use-dependent synaptic short-term plasticity that can account for both short-term depression and short-term facilitation. It is analyzed in the context of the spike response neuron model. Explicit expressions are derived for the synaptic strength as a function of previous spike arrival times. These results are then used to investigate the behavior ...
