Recently, few studies have investigated the relationships between advice seeking and giving network densities and IT system use. To fill the gap, this study explores IT system use by drawing on theories of advice networks, user adaptation and IT system use. Specifically, four types of user adaptation are examined, including IT adaptation, task adaptation, positive reappraisal and emotional vent...

THIS PAPER IS ELIGIBLE FOR THE STUDENT PAPER AWARD. Maddah-Ali and Niesen (MAN) in 2014 surprisingly showed that it is possible to serve an arbitrarily large number of cache-equipped users with a constant number of transmissions by using coded caching in shared-link broadcast networks. This paper studies the tradeoff between the user’s cache size and the file download time for combination netwo...

This paper proposes a new approach for computing probabilities of events in Bayesian networks. The idea is to replace the outward phase of the propagation algorithm by a second (partial) inward propagation phase. The benefit of this idea is that the attention can be focussed on optimizing the inward phase.

Motivated by a strongly growing interest in anonymizing social network data, we investigate the NP-hard Degree Anonymization problem: given an undirected graph, the task is to add a minimum number of edges such that the graph becomes k-anonymous. That is, for each vertex there have to be at least k − 1 other vertices of exactly the same degree. The model of degree anonymization has been introdu...

We propose an algorithm to detect community structure in complex networks based on data field theory. The efficiency and accuracy of the algorithm for computer-simulated and real networks make it feasible to be used for the accurate detection of community structure in complex networks. Using the conductance fluctuating signals measured from gas-liquid two-phase flow dynamic experiments, we cons...

The essence of the Electro Droplet-Jet Technology (EDJT) consists of the production of a linear sequence of monodisperse droplets of a fluid, separated from each other by equal distances. Numerical simulation of a liquid jet dispersion and a two-phase droplet flow problem were performed. The effect of the computational mesh on the predictions was investigated; in particular, the influence of th...

This paper describes two innovations that improve the efficiency and effectiveness of a genetic programming approach to object detection problems. The approach uses genetic programming to construct object detection programs that are applied, in a moving window fashion, to the large images to locate the objects of interest. The first innovation is to break the GP search into two phases with the ...

We studied a three-node quantum network that enables bidirectional communication between two nodes with a half-duplex relay node for transmitting classical messages. A decode-and-forward protocol is used to perform the communication in two phases. In the first phase, the messages of two nodes are transmitted to the relay node. The capacity of the first phase is well-known by previous works. In ...

To reveal information hiding in link space of bibliographical networks, link analysis has been studied from different perspectives in recent years. In this paper, we address a novel problem namely citation prediction, that is: given information about authors, topics, target publication venues as well as time of certain research paper, finding and predicting the citation relationship between a q...
